The cooking apparatus 1 may include a magnetron 40 configured to generate microwaves. The cooking apparatus 1 may cook food by using frictional heat generated by translational motion of water molecules contained in food by irradiating the food with microwaves generated by the magnetron 40. The cooking apparatus 1 may be a microwave oven.

The cooking apparatus 1 may include an inlet 50 to draw in external air.

The inlet 50 may include a first inlet 51 formed at the front 11 of the main body 10 and a second inlet 52 formed at the bottom 12 of the main body 10.

The first inlet 51 may be formed below the door 20 at a region where the front 11 of the main body 10 is formed. In other words, the first inlet 51 may be formed at the front 11 of the main body 10 between the door 20 and the bottom 12 of the main body 10.

The first inlet 51 may be formed in a long shape along the widthwise direction of the main body 10. That is, the first inlet 51 may be formed long in the horizontal direction in the front 11 of the main body 10. The first inlet 51 may be formed in a horizontally extending slit shape. The first inlet 51 may be formed in various shapes. For example, the first inlet 51 may be formed in an oval or polygonal shape.

The first inlet 51 may be formed in the form of a single slit as shown in the drawing or multiple slits. For example, two inlets are arranged in parallel along the widthwise direction that is the lateral direction of the main body 10.

A filter (not shown) or a grill (not shown) for removing foreign substances contained in the air being drawn in may be installed in the first inlet 51.

The second inlet 52 may be formed in a rectangular shape at the bottom 12 of the main body 10. Two second inlets 52 may be arranged in parallel in the lateral direction. A filter 53 for filtering foreign substances contained in the air being drawn in may be installed in the second inlet 53.

The cooking apparatus 1 may include an exhaust port 60. The exhaust port 60 may be located at the top 13 of the main body 10. The exhaust port 60 may be provided to exhaust air drawn in from the inlet 50 to the outside. The exhaust port 60 may be connected to an exhaust duct (not shown) communicating with the outside and may be disposed at a rear region of the top 13 for easy connection to the exhaust duct.

The cooking apparatus 1 may include a connecting duct (not shown) connecting the inlet 50 with the exhaust port 60. The connecting duct may be disposed in the main body 10.

The cooking apparatus 1 may include a blower (not shown) configured to generate a blowing force to draw in external air from the inlet 50 and exhaust air through the exhaust port 60.

Air may be drawn in through the first inlet 51 and the second inlet 52 by one blower, or separate air intake devices to draw in the air may be provided respectively at the first inlet 51 and the second inlet 52. The blower may be disposed in the connecting duct.

The cooking apparatus 1 may include a flow guide 100. The flow guide 100 may be disposed adjacent to the first inlet 51.

The flow guide 100 may be arranged in a long shape along the first inlet 51, and thus the flow guide 100 may be formed in a long shape along the first inlet 51 parallel to the front 11 of the main body 10.

The flow guide 100 may be formed to have a width corresponding to a length of the first inlet 51 in the widthwise direction or a length of the front 11 of the main body 10 in the widthwise direction.

FIG. 4 is a diagram illustrating that a flow guide is located at a first position to guide contaminated air into an inlet in the cooking apparatus of FIG. 2. FIG. 5 is a diagram illustrating that the flow guide is located at a second position to cover the inlet in the cooking apparatus of FIG. 4.

Referring to FIG. 4, the flow guide 100 may be located below the first inlet 51. Although the flow guide 100 is located below the first inlet 51, the flow guide 100 may be coupled not to the bottom 12 of the main body 10 but to the front 11 or an edge between the front 11 and the bottom 12.

The flow guide 100 may be arranged to be inclined downward in the forward direction in a state of being coupled to the edge between the front 11 and the bottom 12. For example, the rear end of the flow guide 100 may be coupled to the edge between the front 11 and the bottom 12, and the front end of the flow guide 100 may be arranged at a lower position than the rear end to be arranged in a downward slope overall.

While contaminated air is drawn in through the first inlet 51 in a state where the flow guide 100 is arranged below the first inlet 51 to be inclined downward in the forward direction, the flow guide 100 may guide the inflow of contaminated air into the first inlet 51. A process of guiding the contaminated air by the flow guide 100 will be described below in detail.

The flow guide 100 may have a first surface 110 arranged at the top and a second surface 120 located at the bottom opposite to the first surface 110 in a state of being arranged to be inclined downward in the forward direction.

In the state where the flow guide 100 is inclined downward in the forward direction, the first surface 110 may be formed convexly upward. For example, the first surface 110 may be formed to have a shape of the upper surface of an airfoil.

Therefore, the first surface 110 may include a leading edge that is a front portion formed as a rounded surface, a middle portion with a gentler curve than the leading edge, and a tailing edge that is a sharp end portion.

On the contrary, in the state where the flow guide 100 is inclined downward, the second surface 120 may be formed as a flat surface facing downward.

Therefore, as the first surface 110 as the upper surface meets the second surface 120 as the lower surface, the flow guide 100 may have an overall airfoil shape that is a streamlined shape.

The main body 10 may include a recession 17 recessed to correspond to the convex shape of the first surface 110.

The recession 17 may be formed at the front of the main body 10 around the first inlet 51. In the state where the flow guide 100 is inclined downward, the recession 17 may constitute the front of the main body 10 in a recessed shape.

The flow guide 100 may be pivotably coupled to the main body 10. For example, the rear end of the flow guide 100 may be pivotably coupled to the edge between the front 11 and the bottom 12. Therefore, the flow guide 100 may pivot about the edge between the front 11 and the bottom 12 and pivot between the first position in which the flow guide 100 is inclined downward and the second position in which the flow guide 100 is arranged to cover the first inlet 51.

Referring to FIG. 5, in a state where the flow guide 100 pivots to the second position, the first surface 110 of the flow guide 100 may be completely accommodated in the recession 17 because the recession 17 is formed to correspond to the first surface 110.

Therefore, in the case where the flow guide 100 is located at the second position, the first inlet 51 is covered with the first surface 110 not to be exposed to the outside, and the second surface 120 may constitute the exterior appearance of the main body 10.

As such, in the case where the flow guide 100 is located at the second position, the second surface 120 may be arranged on the same plane as the front 11 of the main body 10 arranged above the recession 17 without a step and may constitute the front of the main body 10.

In the case where the flow guide 100 is located at the second position, the first inlet 51 may be closed by the flow guide 100, and in this case, the inflow of foreign substances into the first inlet 51 may be blocked by the flow guide 100.

FIG. 6 is a diagram illustrating that a flow guide is located at a first position to guide an inflow of air in a cooking apparatus according to an embodiment. FIG. 7 is a diagram illustrating that the flow guide is located at a second position where the second surface of the flow guide is in contact with the bottom of the main body in the cooking apparatus of FIG. 6.

The cooking apparatus 1 may include a first inlet 51 to draw in contaminated air at the front 11 of the main body 10. The first inlet 51 may be formed below the door 20 at a region where the front 11 of the main body 10 is formed. In other words, the first inlet 51 may be formed at the front 11 of the main body 10 between the door 20 and the bottom 12 of the main body 10, and the front 11 of the main body 10 may be formed as a vertical plane without a recessed structure.

The first inlet 51 may be formed in a long shape along the widthwise direction of the main body 10. That is, the first inlet 51 may be formed lone in the horizontal direction. The first inlet 51 may be formed in a horizontally extending slit shape.

A filter (not shown) or a grill (not shown) for removing foreign substances contained in the air being drawn in may be installed at the first inlet 51.

The flow guide 100 may have a first surface 110 arranged at the top and a second surface 120 located at the bottom opposite to the first surface 110 in a state of being inclined downward in the forward direction.

In the state where the flow guide 100 is inclined downward, the first surface 110 may be formed convexly upward. For example, the first surface 110 may be formed to have a shape of the upper surface of an airfoil.

Therefore, the first surface 110 may include a leading edge that is a front portion formed as a rounded surface, a middle portion with a gentler curve than the leading edge, and a tailing edge that is a sharp end portion.

On the contrary, in the state where the flow guide 100 is inclined downward, the second surface 120 may be formed as a flat surface facing downward.

Therefore, as the first surface 110 as an upper surface meets the second surface 120 as a lower surface, the flow guide 100 may have an overall airfoil shape that is a streamlined shape.

The flow guide 100 may be pivotably coupled to the main body 10. For example, the rear end of the flow guide 100 may be pivotably coupled to the edge between the front 11 and the bottom 12.

The flow guide 100 may pivot about the edge between the front 11 and the bottom 12 to the first position where the flow guide 100 is arranged to be inclined downward. While the contaminated air is drawn in through the first inlet 51 in a state where the flow guide 100 is located at the first position, the flow guide 100 may guide the inflow of contaminated air through the first inlet 51.

In the case where the guiding of the inflow of contaminated air is not required due to cessation of the intake of the contaminated air, the flow guide 100 may pivot to the second position.

In the case where the flow guide 100 is located at the second position, the second surface 120 may be arranged to be in contact with the bottom 12 of the main body 10. While the flow guide 100 is located at the second position, the second surface 120 may be located to face upward in a state of facing the bottom 12 of the main body 10, and the first surface 110 may be located to face downward.

FIG. 8 is a side cross-sectional view of a cooking apparatus in which the flow guide shown in FIG. 4 is arranged.

The flow guide 100 may be pivotably coupled to the main body 10. The cooking apparatus 1 may include a hinge that pivotably supports the flow guide 100 relative to the main body 10.

The hinge 130 may be located at the edge between the front 11 and the bottom 12 of the main body 10. Accordingly, the flow guide 100 may pivot about the edge between the front 11 and the bottom 12 while being pivotably supported by the hinge 130 and pivot between the first position where the flow guide 100 is arranged to be inclined downward and the second position where the flow guide 100 is arranged to cover the first inlet 51.

The hinge 130 may consist of a torque hinge to maintain a stationary state at a desired position and an angle hinge to stop at a specific angle. Therefore, the user may move the flow guide 100 to the first position and the second position by pivoting the flow guide 100, and the hinge 130 may maintain the first position in which the flow guide 100 guides the intake of contaminated air.

In the case where the flow guide 100 is located at the first position, the first surface 110 may be arranged to be inclined downward. In this state, in the case where the air intake through the first inlet 51 occurs, an intake of contaminated air around the flow guide 100 may be guided by the first surface 110 into the first inlet 51.

In the state where the flow guide 100 is inclined downward, the first surface 110 may be formed convexly upward, for example, the first surface 110 may be formed to have a shape of the upper surface of an airfoil as described above.

As the first surface 110 is formed as a convex curve, the intake of contaminated air around the flow guide 100 into the first inlet 51 may be guided by the Coanda effect.

The Coanda effect refers to a tendency of a fluid such as air or water flowing along a curved surface to flow in a state of being attached to the curved surface without being separated therefrom. This effect is noticeable, particularly, when a fluid stream is directed to a curved surface, and may be represented as a phenomenon in which the fluid stream flows along the curvature in a state of being attached to the surface.

Therefore, contaminated air around the flow guide 100 is not separated from the convex first surface 110, but the flow thereof is guided along the first surface 110 toward the first inlet 51.

The Coanda effect may be maximized in the shape of an airfoil which is the cross-sectional shape of an airplane wing, and the flow guide 100 may be formed to have an airfoil shape to guide the airflow by the Coanda effect.

At the tip of the flow guide 100, the contaminated air is divided into the first surface 110 and the second surface 120, the air flowing along the first surface 110 is guided to move into the first inlet 51, and contaminated air guided by the second surface 120 may be guided to be drawn in through a second inlet 52 (See FIG. 3).

To maximize the guiding effect by the flow guide 100, the flow guide 100 may be arranged at an appropriate angle. For example, the flow guide 100 may be arranged such that a vertical angle between the second surface 120 and the front 11 of the main body 10 is from 40° to 50°.

A length L of the flow guide 100 in the forward-backward direction may be smaller than a height H of the front 11 of the main body 10. Therefore, the flow guide 100 may move to the second position covering the recession 17 without interfering with the door 20.

FIG. 9 is a partial side cross-sectional view of a cooking apparatus according to an embodiment.

The cooking apparatus 1 may include a driving device 200 configured to drive the flow guide 100.

The driving device 200 may be located adjacent to the hinge 130 pivotably supporting the flow guide 100. The driving device 200 may be arranged adjacent to the edge between the front 11 and the bottom 12 of the main body 10.

The driving device 200 may include a driving motor 210 configured to generate a driving force. The driving motor 210 may include a driving shaft 211 that rotates by the driving force.

Upon operation of the driving motor 210, the driving shaft 211 may transmit the driving force to the outside of the driving motor 210 while rotating.

The driving motor 210 may include a driving pulley 220. The driving pulley 220 may be coupled to the driving shaft 211 to rotate together with the driving shaft 211.

The driving device 200 may include a driven pulley 230. The driven pulley 230 may be coupled to the hinge shaft 131 of the hinge 130. The hinge shaft 131 may serve as a rotation axis of the flow guide 100.

The driving device 200 may include a driving belt 240. The driving belt 240 may be connected between the driving pulley 220 and the driven pulley 230. Therefore, the driving force of the driving motor 210 is transmitted to the hinge shaft 131 through the driving pulley 220, the driving belt 240, and the driven pulley 230, thereby allowing the flow guide 100 to pivot.

The flow guide 100 may pivot between the first position where the flow guide 100 is arranged to be inclined downward and the second position where the flow guide 100 is arranged to cover the first inlet 51, by the driving device 200. In the state where the flow guide 100 is located at the second position, the first surface 110 may be accommodated in the recession 17.

The operation of the driving device 200 may be controlled by a controller (not shown). For example, in the case where the power of the cooking apparatus 1 is turned off, the controller may control the driving device 200 to move the flow guide 100 to the second position. In the case where the power of the cooking apparatus 1 is turned on, the controller may control the driving device 200 to move the flow guide 100 to the first position where the flow guide 100 guides the inflow of contaminated air.

The flow guide 100 may be controlled by the driving device 200 to move to the first position only when the air intake device (not shown) operates in the cooking apparatus 1. For example, once the air intake device operates, the controller may control the driving device 200 to move the flow guide 100 to the first position. Once the air intake device is turned off, the controller may control the driving device 200 to move the flow guide 100 to the second position.

Therefore, in the case where an intake of contaminated air by the cooking apparatus 1 is required without a user's direct intervention, the flow guide 100 may automatically move to the first position to guide the air intake. In the case where the intake of contaminated air is not required, the flow guide 100 may automatically move to the second position.

The driving device 200 may include a driven pulley 230. The driven pulley 230 may be coupled to the hinge shaft 131 of the hinge 130. The hinge shaft 131 may serve as a rotation axis of the flow guide 100.

The driving device 200 may include a driving belt 240. The driving belt 240 may be connected between the driving pulley 220 and the driven pulley 230. Therefore, the driving force of the driving motor 210 may be transmitted to the hinge shaft 131 through the driving pulley 220, the driving belt 240, and the driven pulley 230, thereby allowing the flow guide 100 to pivot.

The flow guide 100 may pivot between the first position where the flow guide 100 is arranged to be inclined downward and the second position where the second surface of the flow guide 100 is in contact with the bottom 12 of the main body 10.

The operation of the driving device 200 may be controlled by a controller (not shown). For example, in the case where the power of the cooking apparatus 1 is switched off, the controller may control the driving device 200 to move the flow guide 100 to the second position. In the case where the power of the cooking apparatus 1 is turned on, the controller may control the driving device 200 to move the flow guide 100 to the first position where the flow guide 100 guides the inflow of contaminated air.

The flow guide 100 may be controlled by the driving device 200 to move to the first position only when the air intake device (not shown) operates in the cooking apparatus 1. For example, once the air intake device operates, the controller controls the driving device 200 to move the flow guide 100 to the first position. Once the air intake device is turned off, the controller controls the driving device 200 to move the flow guide 100 to the second position.

Therefore, in the case where an intake of contaminated air by the cooking apparatus 1 is required without a user's direct intervention, the flow guide 100 may automatically move to the first position to induce the air intake. In the case where the intake of contaminated air is not required, the flow guide 100 may automatically move to the second position.
