RANGE HOOD INSERT ASSEMBLY

Description

FIELD

The present disclosure relates to range hoods for ventilating food preparation locations, like kitchens. More particularly, the present disclosure relates to a range hood insert assembly for being installed in conjunction with a custom vent shell arrangement in a kitchen.

BACKGROUND

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

A range hood is a kitchen appliance that is positioned above a cooking surfaces, like a range, and configured to ventilate and remove smoke, steam, odors, and airborne grease that can be produced while cooking. Often in custom kitchen applications, a wall-mounted custom cabinet or wood feature is configured to receive and surround a range hood insert assembly, such that the assembly is able to perform its ventilation function while concealed by the cabinet feature. A standard installation method of such an assembly includes first installing a custom hood shell into a specific cabinet cutout. Next, the assembly is lifted into the hood shell and held it in place for an extended period of time while the insert is secured to the hood shell via an arrangement of fasteners. This scenario creates installation challenges due to a weight of the assembly – which often weigh anywhere from 50 to 70 lbs. Another installation process includes securing the assembly inside a custom shell using a series of L-shaped brackets and Phillips-head screws across all sides of the assembly to ensure that it is safely secured. Due to a plethora of custom shells that exist, the L-shaped bracket approach does not always work. In these instances, holes may be pre-drilled into the assembly itself, and screws may be used to secure the insert into the custom shell. Regardless of the installation method, the main challenge in installing range hood insert assemblies is dealing with the weight of the assembly. It can take several minutes to a half hour or longer to safely install the assembly, and such installs are typically a minimum a two-person job, if not more, to ensure that the assembly is satisfactorily held in place from below. Additionally, range hood insert assemblies by design put a full weight of the assembly on the custom shell, thus causing unnecessary strain, meaning custom cabinet or wood shells typically have to be built and fortified to safely withstand the weight of the assembly. Finally, only after the range hood insert assembly is successfully installed into the custom hood shell can a customer move onto the next stage of installing ducting from the top of the assembly into the ceiling of the kitchen to provide proper ventilation, all while the full weight of the assembly is leveraged against the custom shell. Once the ducting is installed, installation can be finalized by securing a custom-made chimney onto the custom shell.

The embodiments of the subject range hood insert assembly are easy to install, require little man-power, provide flexibility in hood shell designs, and are robustly connected to the adjacent wall.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

Example embodiments of a range hood insert assembly 10A, 10B, 10C, 10D, 10E and associated methods embodying the teachings of the present disclosure will now be described more fully with reference to the accompanying drawings. However, the example embodiments are only provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that the example embodiments may be embodied in many different forms that may be combined in various ways, and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.

More particularly, referring to the figures, wherein like numerals indicate corresponding parts throughout the several views, embodiments of a range hood insert assembly 10A, 10B, 10C, 10D, 10E are provided. As best illustrated in FIG. 1A, the range hood insert assembly 10A, 10B, 10C, 10D, 10E is configured to be positioned in an insert opening of a hood shell 12 for an oven. For example, the hood shell 12 may be a wall 66 mounted custom cabinet or wood feature that is configured to receive and surround a range hood insert assembly 10A, 10B, 10C, 10D, 10E, such that the range hood insert assembly 10A, 10B, 10C, 10D, 10E is able to perform its ventilation function while concealed by the hood shell 12. The hood shell 12 may be connected to the wall and insert assembly 10A, 10B, 10C, 10D, 10E in various ways.

FIGS. 1A-1F show a first embodiment of the range hood insert 10A. The range hood insert 10A has a chassis 14 that is generally box shaped, with a top wall 16, a bottom wall 18, side walls 20 between the top and bottom walls 16, 18, and front and rear walls 22, 24 between the top side walls 20. The chassis 14 defines a compartment 26. A vent 28 is defined along the bottom wall 18. As best shown in FIG. 1B, a grill 30 overlies the vent 28. A pair of lights 32 are located along the bottom wall 18 for illuminating a range below the range hood insert assembly 10A. Any number of lights 32 and slots of the vent 28 may be used. The top wall 16 of the chassis 14 defines an exhaust opening 34 which is fluidly connected to the vent 28. A rim 36 extends upwardly from the top wall 16 of the chassis 14 around the exhaust opening 34. According to the described embodiments, the exhaust opening 34 is square-shaped, and the rim 36 is comprised of four segments, but other arrangements may be used without departing from the scope of the subject disclosure. As shown, the exhaust opening 34 may be separated into any number of openings 34 by a divider.

The range hood insert assembly 10A also includes a smoke collecting box 38 that has an open bottom end 40 which is connected to the top wall 16 of the chassis 14 in alignment with the exhaust opening 34. More particularly, the bottom end 40 surrounds the rim 36 of the chassis 14. The smoke collecting box 38 also has a top surface 42 that is opposite the bottom end 40, and a front surface 44, a rear surface 46 opposite the front surface 44 and a pair of side surfaces 48 that extend between the front and rear surfaces 44, 46. A plurality of fasteners 50 connect the front, rear and side surfaces 44, 46, 48 to the rim 36 of the chassis 14 to connect the smoke collecting box 38 to the chassis 14. The smoke collecting box 38 defines an interior that is fluidly connected to the exhaust opening 34 of the chassis 14. The top surface 42 of the smoke collecting box 38 defines an outlet 52 for being coupled with a conduit 54 which ultimately extends through the shell 12 and to the atmosphere. An exhaust fan 56 (schematically shown in FIG. 1A) is located in the interior of the smoke collecting box 38 for pulling air through the vent 28, into the smoke collecting box 38 and through the conduit 54 such that it may be exhausted to the atmosphere.

As shown in FIG. 1B, a series of buttons 58 are located along the bottom wall 18 of the chassis 14 for allowing an operator to selectively activate the lights 32 and the exhaust fan 56. Any number of buttons 58 may be used, and they may serve various features. The buttons 58 may be connected to an associated controller 59 (schematically shown in FIG. 1A) which can provide variability in operation of the lights 32 and exhaust fan 56. Other input devices, e.g., a smart phone or tablet, may be used to control the lights 32 and exhaust fan 56. A control box 70 is connected to the smoke collecting box 38 adjacent to the outlet 52 for containing controlling equipment such as the controller 59 (schematically shown).

A flange 60 overlies, and is connected to the rear surface 48 of the smoke collecting box 38. The flange 60 extends beyond the top surface 42 of the smoke collecting box 38 in the vertical direction such that an exposed portion of the flange 60 is visible. The flange 60 defines a pair of orifices 62 along the exposed portion for receiving fasteners 64, e.g., bolts or screws, to connect the range hood insert assembly 10A to a wall 66. According to embodiments, the orifices 62 are spaced from one another at a distance which permits the fasteners 64 to be connected to studs 68 or other mounting features on the wall 66 (shown schematically in FIG. 1A).

FIGS. 2A-5D illustrate four additional embodiments of the range hood insert assembly 10B, 10C, 10D, 10E. These embodiments are generally structurally the same, but with smaller and/or larger features than those of the first embodiment of the range hood insert assembly 10A in order to accommodate hood shells 12 of different sizes.

As shown in FIG. 7, a method 100 for installing a range hood insert assembly 10A, 10B, 10C, 10D, 10E is also provided. The method includes 102 connecting the smoke collecting box 38 to the rim 36 of the chassis 14. This may include driving a plurality of fasteners 50, such as screws or bolts, through the smoke collecting box 38 and the rim 36 of the chassis 14. The method also includes 104 securing a pair of fasteners 64, such as screws or bolts, to the wall 66 into a pair of studs 68 or other supports in, or along the wall 66. This step may include pre-drilling holes into the studs 68 or other supports. The method also includes 106 positioning the chassis 14 and smoke collecting box 38 against the wall 66, with the orifices 62 of the flange 60 receiving the fasteners 64. This step may include one or more installers lifting and positioning the chassis 14 and smoke collecting box 38 in place. The method then includes 108 tightening the fasteners 64 to fix the chassis 14 and the smoke collecting box 38 to the wall 66. Once the chassis 14 and the smoke collecting box 38 are in place, the method includes 108 sliding a hood shell 12 around the assembled range hood insert assembly 10A, 10B, 10C, 10D, 10E.

This process not only allows an installer to fully install exhaust conduits 54/ducting without maneuvering around a custom shell 12 because the full weight of the range hood insert assembly 10A, 10B, 10C, 10D, 10E is shifted to the kitchen wall. This provides an overall sturdy mount. With the range hood insert assembly 10A, 10B, 10C, 10D, 10E successfully mounted on the wall 66, the installer can then install specifically designed hood shell 12 by easily sliding it onto the hood insert assembly 10A, 10B, 10C, 10D, 10E by crafting the shell 12 around the precise width and depth dimensions for the specific range hood insert assembly 10A, 10B, 10C, 10D, 10E. This process is fundamental for installation scenarios where an oven or stove/range is already installed below the range hood insert assembly 10A, 10B, 10C, 10D, 10E. Installation parameters often require hoods to be between 30 inches and 36 inches above the cooktop below – this exacerbates the issue of multiple people holding a heavy hood in place to insert it into a shell 12 due to having three feet or less of space with which to work.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in that particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.

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 later, or intervening element 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 described 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 foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
