FIELD

The present technology relates to a heating, ventilation, and air conditioning (HVAC) system, and, more particularly, to a device and method for cleaning and maintaining a condensate drain line and pan in such systems.

INTRODUCTION

This section provides background information related to the present disclosure which is not necessarily prior art.

Heating, ventilation, and air conditioning (HVAC) systems serve to control the indoor climate of various structures, providing comfort and maintaining air quality for an occupant. However, the HVAC system faces ongoing challenges related to condensation management, which can lead to various issues if not properly addressed. One of the concerns in an HVAC system involves the accumulation of condensate in a drain pan and a drain line. As warm, humid air passes over the cooling coils of an air conditioning unit, moisture condenses and collects in the HVAC drain pan, requiring efficient removal from the system to reduce overflow and water damage. Over time, the condensate drain line can become clogged with debris, algae, mold, and other microorganisms that thrive in the moist environment. The blockages can impede the drainage of condensate, leading to backups and a potential overflow situation that can damage HVAC equipment and surrounding building materials, potentially causing costly repairs and disruptions to the operation of the HVAC system.

Stagnant water in the HVAC drain pan and clogged lines creates an ideal breeding ground for bacteria and mold, which can negatively impact indoor air quality and pose health complications to building occupants. The growth of the microorganisms can also contribute to unpleasant odors and further exacerbate drainage issues. Maintenance of the HVAC system has relied on manual cleaning and periodic treatments, which can be time-consuming, labor-intensive, and often neglected. The solution often results in reactive rather than proactive maintenance, addressing problems only after they have become severe enough to cause noticeable issues.

Certain HVAC drain pan and line maintenance solutions attempt to address the aforementioned issues with microorganisms and condensate. These solutions can present their own issues, however, and can employ complex mechanisms for attachment and fluid dispensing that can be difficult to install and maintain. Solutions that rely on electronic components and power sources also introduce potential points of failure and increase overall complexity. Such a complex electronic system can introduce potential points of failure, unlike straightforward approaches that are easy to install, operate, and maintain without the need for batteries, power sources, or internet connections.

Accordingly, there is a continuing need for a simple, reliable, and effective solution for maintaining HVAC condensate drain systems that provides consistent treatment of drain pans and lines, requires minimal maintenance, and is easy to install and operate without the need for complex electronic systems or power sources, while addressing the issues of clogging, microbial growth, and overflow prevention and being adaptable to various HVAC system configurations.

DETAILED DESCRIPTION

The following description of technology is merely exemplary in nature of the subject matter, manufacture and use of one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application or in such other applications as may be filed claiming priority to this application, or patents issuing therefrom.

Regarding methods disclosed, the order of the steps presented is exemplary in nature, and thus, the order of the steps can be different in various embodiments, including where certain steps can be simultaneously performed, unless expressly stated otherwise. “A” and “an” as used herein indicate “at least one” of the item is present; a plurality of such items may be present, when possible. Except where otherwise expressly indicated, all numerical quantities in this description are to be understood as modified by the word “about” and all geometric and spatial descriptors are to be understood as modified by the word “substantially” in describing the broadest scope of the technology. “About” when applied to numerical values indicates that the calculation or the measurement allows some slight imprecision in the value (with some approach to exactness in the value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by “about” and/or “substantially” is not otherwise understood in the art with this ordinary meaning, then “about” and/or “substantially” as used herein indicates at least variations that may arise from ordinary methods of measuring or using such parameters.

Although the open-ended term “comprising,” as a synonym of non-restrictive terms such as including, containing, or having, is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more limiting terms such as “consisting of” or “consisting essentially of.” Thus, for any given embodiment reciting materials, components, or process steps, the present technology also specifically includes embodiments consisting of, or consisting essentially of, such materials, components, or process steps excluding additional materials, components or processes (for consisting of) and excluding additional materials, components or processes affecting the significant properties of the embodiment (for consisting essentially of), even though such additional materials, components or processes are not explicitly recited in this application. For example, recitation of a composition or process reciting elements A, B and C specifically envisions embodiments consisting of, and consisting essentially of, A, B and C, excluding an element D that may be recited in the art, even though element D is not explicitly described as being excluded herein.

Disclosures of ranges are, unless specified otherwise, inclusive of endpoints and include all distinct values and further divided ranges within the entire range. Thus, for example, a range of “from A to B” or “from about A to about B” is inclusive of A and of B. Disclosure of values and ranges of values for specific parameters (such as amounts, weight percentages, etc.) are not exclusive of other values and ranges of values useful herein. It is envisioned that two or more specific exemplified values for a given parameter may define endpoints for a range of values that may be claimed for the parameter. For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that Parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if Parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, 3-9, and so on.

When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The present technology provides an HVAC condensate management solution that allows for a simple, reliable, and effective way to maintain a drain pan and drain line. The present technology addresses the ongoing challenges related to condensation management in an HVAC system, including the accumulation of condensate, clogging of drain lines, and the growth of microorganisms that can impact indoor air quality. By offering a consistent and automated approach to treating a drain pan and line, the present technology reduces the need for manual cleaning and periodic treatments, which are often time-consuming, labor-intensive, and frequently neglected. Furthermore, the present technology enhances the overall efficiency and longevity of HVAC systems by militating against issues such as overflow, water damage, and equipment malfunction caused by improper condensate management. The present technology may also be provided in the form of a kit for ease of installation onsite with the HVAC system.

The present technology provides a device 100 for cleaning and maintaining a heating, ventilation, and air conditioning (HVAC) drain pan 101 in an HVAC system 103 with cleaning fluid 105, shown generally in FIGS. 1-5. The device 100 can assist with the management of condensate in the HVAC system 103 by providing consistent and controlled treatment of the HVAC drain pan 101 and lines to address common issues associated with moisture buildup. By dispensing a predetermined amount of cleaning fluid 105 (e.g., every few months), the device 100 can maintain cleanliness in both the HVAC drain pan 101 and the entire drain line over an extended period, effectively addressing the accumulation of condensate, clogging of the drain line with debris, algae and mold, and the growth of microorganisms that can negatively impact indoor air quality and pose health risks to building occupants. The device 100 can address ongoing challenges in HVAC system 103 maintenance by providing a simple, reliable solution that can reduce the need for time-consuming, labor-intensive manual cleaning and periodic treatments that are often neglected, while addressing issues such as overflow, water damage, and equipment malfunction caused by improper condensate management.

With reference to FIG. 1, the device 100 can include a container 102, a hose 104, and a clip 106. In certain embodiments, the device 100 can further include a drain line fitting 108. The container 102 can include a body 110 that serves as the housing for the cleaning fluid 105, providing a secure and reliable storage solution for the device 100. The body 110 can include an opening 112 that allows for the placement of cleaning fluid 105 into the container 102, and the body 110 can hold and store the cleaning fluid 105 during operation, ensuring continuous availability for the cleaning process. The body 110 can have a generally rectangular or cylindrical shape with dimensions that can provide sufficient capacity for the cleaning fluid 105 while maintaining a compact profile suitable for mounting on HVAC equipment. A skilled artisan can select suitable dimensions for the body 110 within the scope of the present disclosure. The body 110 can offer the advantage of easy installation in the confined space of HVAC housing while providing adequate fluid capacity. For example, the body 110 can hold at least 32 ounces of cleaning fluid 105, which can be sufficient for multiple treatment cycles spanning several months of operation.

With reference to FIG. 2, the body 110 can include various coupling mechanisms 107 for securing the container to the HVAC system 103, providing flexibility for different installation scenarios and HVAC system 103 configurations. The body 100 can have a magnetic backing 109 for removable attachment to the HVAC system 103, which provides a secure and tool-free installation method that allows the device 100 to be magnetically mounted to metal surfaces of HVAC system 103 without requiring permanent modifications. Additionally, the body 110 can include an aperture 111 or notch that allows for wall mounting using mechanical fasteners such as nails, screws, anchors, or bolts, for example, offering an alternative installation method when magnetic attachment is not feasible or preferred. A skilled artisan can select a suitable coupling mechanism for coupling the body 110 to the HVAC system 103.

The body 110 can be formed of a plastic material, which can provide the advantage of lightweight construction, corrosion resistance, and cost-effective manufacturing. For example, the body 110 can be formed from polyethylene, including both high-density polyethylene and low-density polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polycarbonate, acrylic, polyethylene terephthalate, polystyrene, and combinations thereof. Other suitable materials for forming the body 110 can include metal, composite materials, or other durable materials capable of containing cleaning fluid 105 without degradation. The choice of plastic materials can provide chemical compatibility with various cleaning solutions while maintaining structural integrity over extended periods of use. A skilled artisan can select a suitable material for the body 110 within the scope of the present disclosure.

The body 110 can be constructed as opaque, translucent, or transparent depending on the specific requirements of a user, with each option offering distinct advantages. Opaque construction can protect light-sensitive cleaning fluid 105 from degradation, while transparent or translucent materials can allow for visual monitoring of fluid levels and condition. In certain embodiments, the body 110 can include a viewing window or window slot that allows users to monitor the fluid level without opening the container 102, providing the advantage of quick visual inspection without compromising the sealed environment of the cleaning fluid 105. The viewing window can be positioned on the front or side of the body to provide clear visibility of the cleaning fluid 105 contents while maintaining the structural integrity of the container.

As shown in FIG. 1, the body can include fluid level measurement system 114, such as an ounce marking or graduation, that can allow the user to know how much cleaning fluid 105 remains in the body 110, providing the advantage of precise monitoring for maintenance scheduling and refill planning. The measurement system 114 can be graduated and can range from 4 oz to 32 oz, for example, providing an indicator for monitoring fluid consumption and determining when refilling is necessary, which can help users optimize maintenance intervals and ensure continuous operation. The graduated measurement system 114 can reduce the amount of guesswork required by the user and can enable predictive maintenance scheduling based on actual consumption rates.

With continued reference to FIG. 1, the container 102 can include a lid 116 that covers the opening 112 of the body 110. The lid 116 can keep dirt, debris, and other contaminants out of the cleaning fluid 105 during operation, ensuring the purity and effectiveness of the cleaning solution throughout the operational cycle. The ability of the lid 116 to provide contamination protection can be particularly important in HVAC environments where dust, debris, and other airborne particles are common. The lid 116 can be removably coupled to the body 110 via various mechanisms including a hinge connection 118. The hinge connection 118 can allow the lid 116 to pivot open and closed, offering the advantage of a tethered that should not be misplaced during refilling operations. Alternative coupling methods can include snap-fit connections, threaded connections, or other suitable fastening mechanisms that can provide secure closure while allowing for easy removal when refilling is required. A skilled artisan can select a suitable connection means within the scope of the present disclosure.

With continued reference to FIG. 1, the lid 116 can include an integrated breather 120 that can allow air to enter the container as cleaning fluid 105 leaves the body 110 via a valve 122. The integrated breather 120 can maintain optimal atmospheric pressure within the container 102 and can facilitate smooth fluid flow without creating a vacuum that could impede the dispensing operation, providing the advantage of consistent and reliable fluid delivery throughout the operational cycle. The integrated breather 120 can reduce the need for a separate venting component, reducing system complexity and potential failure points while ensuring that the cleaning fluid 105 can flow freely under gravity feed without pressure-related flow interruptions.

As shown in FIGS. 1-3, the container 102 can include the valve 122 configured as a ball valve 124. The ball valve 124 can be threadably coupled to the body 110 opposite the opening 112 to allow gravity to move the cleaning fluid 105 from the container 102 through the hose 104. In this way, the device 100 can move the cleaning fluid 105 through the device 100 without requiring an external pumping mechanism. The gravity-fed ball valve 124 can provide reliable fluid delivery while maintaining the simplicity of the overall device by reducing the need for complex pumping equipment or electrical components. It should be appreciated that the ball valve 124 can include a straight neck or an angled neck. For example, the angled neck can be disposed at an angle between 0° and 180°. In a particular embodiment, the neck can be angled an approximately 90°. A skilled artisan can select a suitable neck for the ball valve 124 within the scope of the present disclosure.

The ball valve 124 can serve as the primary control mechanism for regulating the release of cleaning fluid 105 from the container 102, allowing for precise control over when and how much fluid is dispensed. In a particular embodiment, the ball valve 124 can include a manual ball valve that allows the user to manually actuate the ball valve 124 to control fluid flow. The manual operation can provide the advantage of allowing the user to clean the HVAC drain pan 101 and drain lines outside of scheduled maintenance intervals if the user observes that additional cleaning fluid 105 is needed, such as when visual inspection reveals increased algae growth, debris accumulation, or other conditions that would benefit from additional treatment.

The manual control capability of the ball valve 124 can give the user the flexibility to respond to changing conditions in the HVAC system 103 and can ensure optimal performance regardless of seasonal variations or unusual circumstances that might require more frequent treatment.

Additionally, the ball valve 124 can be particularly effective with militating against the cleaning fluid 105 leaking from the container 102 due to the ball valve 124 being able to efficiently stop cleaning fluid flow 105.

It should be appreciated that the ball valve 124 can be constructed from various materials depending on the specific application requirements and chemical compatibility with the cleaning fluid 105 being used. The valve 122 components can be formed from brass, stainless steel, plastic materials such as PVC or polypropylene, or other materials that can provide durability and resistance to corrosion from cleaning solutions. The valve 122 can include internal ball and seat components that can be manufactured from materials that maintain sealing properties over extended periods of exposure to cleaning fluid 105, ensuring reliable operation throughout the service life of the device 100. A skilled artisan can select suitable materials for the valve 122 within the scope of the present disclosure.

The ball valve 124 can include a rubber seal or gasket where coupled to the body 110 to militate against leaking and ensure a secure, fluid-tight connection. The rubber seal can be positioned at the threaded connection point or coupling interface between the valve 122 and the body 110, providing a reliable barrier against fluid leakage that can compromise the effectiveness of the device 100 and/or create unwanted dripping. The rubber seal can be made from materials such as EPDM, nitrile, or other elastomeric compounds that can maintain sealing properties when exposed to cleaning fluid 105 and can accommodate thermal expansion and contraction cycles typical in HVAC environments. A skilled artisan can select a suitable material for the seal within the scope of the present disclosure. The sealing arrangement can ensure that all cleaning fluid 105 is directed through the intended flow path to the HVAC drain pan 101 rather than being lost through leakage, maximizing the efficiency of the cleaning operation while maintaining a clean and professional installation appearance.

With reference to FIGS. 1 and 3-4, the device 100 can include the hose 104. The hose 104 can be coupled to the valve 122 of the container 102 and to the drain line fitting 108, providing a fluid pathway for transporting the cleaning fluid 105 from the container to the HVAC drain pan. In certain embodiments, where the fitting 108 is not coupled to the hose 104, the hose 104 can rest within the HVAC drain pan 101 itself. The hose 104 can serve as the conduit that connects the valve-controlled fluid release mechanism to the point of application in the HVAC drain pan 101, ensuring that cleaning fluid 105 reaches the intended destination without loss or spillage.

The hose 104 can be constructed from various materials suitable for conveying cleaning fluid 105, including clear or white tubing material. In certain embodiments, the clear tubing can allow for visual confirmation of fluid flow. The hose 104 can have dimensional characteristics that facilitate optimal flow rates, with the hose 104 capable of accommodating the cleaning fluid 105 volumes dispensed by the ball valve while maintaining appropriate flow characteristics for gravity-fed operation. For example, the hose 104 can include â…ś inch diameter tubing in a particular embodiment. A skilled artisan can select a suitable tubing and tubing diameter within the scope of the present disclosure.

It should be noted that the hose 104 can be flexible to allow the hose 104 to be shaped and positioned according to the specific installation requirements of the HVAC system 103. The flexibility can allow the device 100 to accommodate variations in equipment layout, available mounting space, and routing requirements that differ between residential and commercial installation. The flexible nature of the hose 104 can enable a technician to customize the installation to achieve optimal fluid delivery while maintaining a neat and organized appearance that does not interfere with other HVAC components or maintenance access.

With reference to FIG. 3, the hose 104 can utilize one or more clips 106 for securing and organizing the hose 104 to the HVAC system 103 to maintain a neat installation, which can help organize and secure the hose 104 while militating against tangling and promoting a professional appearance. The clips 106 can be positioned on various surfaces of the HVAC system 103 to route the hose 104 in an orderly manner that avoids interference with other system components. In certain embodiments, the clip 106 can be magnetic to allow for the device 100 to be quickly and easily installed and repositioned should the pathway of the hose 104 require changing. Alternatively, the clip 106 can include a mechanical fastener such as a screw or a bolt, a hook and loop attachment, a suction cup attachment, a stick on attachment, and combinations thereof. A skilled artisan can select a suitable attachment between the clip 106 and the HVAC system 103 within the scope of the present disclosure.

It should be appreciated that the visual transparency of hose 104 can provide the additional benefit of allowing technicians and users to confirm that cleaning fluid 105 is flowing through the device 100, which can aid in troubleshooting and ensuring optimal operation of the device 100. The visual confirmation capability can be particularly valuable during initial installation testing and routine maintenance checks to verify that the device 100 is functioning as intended.

With reference to FIG. 3, the clip 106 can have a connector 126 for holding the hose 104, which can facilitate easy assembly and disassembly of device 100. The connector 126 can allow for quick connection of the hose 104 to the clip during installation but can also enable rapid removal of the hose 104 if necessary for maintenance, service, or reconfiguration of the device 100. The connector 126 can reduce the need for tools or complex procedures when connecting or disconnecting the hose 104, making the device 100 more user-friendly for both the installation technician and end user who may need to perform routine maintenance.

In certain embodiments, the connector 126 can include a push-in connector 128 having a substantially C-shaped cross-section to allow for the hose to be pushed into the clip 106 and for the clip 106 to hold the hose 104 securely while still permitting easy insertion and removal, as shown in FIG. 1. The C-shaped configuration can provide a gripping action that can cradle the hose 104 along a portion of a circumference of the hose 104, creating sufficient retention force to keep the hose in position during normal operation while allowing for manual insertion and extraction when needed. The C-shaped configuration can also accommodate slight variations in hose diameter and can provide flexibility to account for thermal expansion or contraction of the hose material. Alternatively, the connector 126 can include a hinged clamp, a twist-lock retention, a sliding gate mechanism, a spring-loaded jaw, an elastic retention band, and combinations thereof. In certain embodiments, the hose 104 and the clip 106 can be integrated such that the connector 126 can be fixed on the hose 104. In a further embodiment, the connector 126 can be a closed loop such that the connector 126 is threaded onto the hose 104 and moved positionally on the hose 104 to the desired location for installation. A skilled artisan can select a suitable connector 126 within the scope of the present disclosure.

As shown in FIGS. 3 and 5, the device 100 can include the drain line fitting 108. The drain line fitting 108 can be coupled to the hose 104 opposite the valve 122. The drain line fitting 108 can be inserted into the HVAC drain pan 101, providing an interface between the device 100 and the point of application within the HVAC system 103. The drain line fitting 108 can serve as a terminal component of the device 100, ensuring that the cleaning fluid 105 is delivered to the HVAC drain pan 101 where the cleaning fluid 105 can perform the intended function of addressing algae growth, debris accumulation, and microbial buildup that can occur in the HVAC system 103.

It should be appreciated that the device 100 can include various drain line fittings 108 to allow the user to select the optimal drain line fitting for the specific HVAC system 103 configuration. In certain embodiments, the drain line fitting 108 can be selected from the group including a Y-fitting, a straight fitting, an L-plug-in, a T-fitting, and an L butt-joint. Each of the drain line fittings 108 can provide flexibility to accommodate the wide variety of HVAC systems 103 and installation requirements encountered in both residential and commercial applications.
