[0078] Figure 1 This is a perspective view of a cooking apparatus according to an embodiment. Figure 2 It is shown in Figure 1 A diagram showing the middle gate 20 in an open state.

[0079] The cooking device in the embodiment can be positioned above a location where a heating cooking device, such as a heated oven or a gas stove, is located vertically separated from the heating cooking device.

[0080] With this configuration of cooking equipment, users can conveniently use the cooking apparatus, which includes the cooking device. Furthermore, the cooking apparatus can function as an exhaust hood for the heating cooking device located below. In this case, the cooking apparatus may have a component that serves as an exhaust hood.

[0081] The cooking device can use microwaves, which are a type of electromagnetic wave, and / or heater heat to cook food. The cooking device may include a body 10 forming a cavity 11 and a door 20 for opening and closing the cavity 11.

[0082] Food to be cooked can be placed in the cavity 11. The door 20 can be configured in front of the cavity 11 and rotatably mounted on the main body 10, so that the cavity 11 can be opened and closed.

[0083] The cooking equipment can function as an exhaust hood to expel foreign matter in the form of gaseous substances from the heating and cooking device located below to the outside. For this purpose, a vent 13 can be provided on the upper part of the main body 10 to expel moisture, oil vapor, etc. generated from the heating and cooking device located below the cooking equipment to the outside.

[0084] The main body 10 may also include a front panel 12, which is disposed at the entrance edge of the cavity 11. When the door 20 is closed, one side of the front panel 12 is configured to face the side of the choke member 170 to close the cavity 11.

[0085] The front panel 12 can surround the entrance edge of the cavity 11 and can be configured to protrude by a specified width. Therefore, when the door 20 is closed, the edge portion of the door 20 and the cavity 11 can overlap each other.

[0086] With this structure, the front panel 12 seals the cavity 11 when the door 20 is closed, thereby preventing oil, moisture, oil vapor and other substances generated during the cooking process of food placed in the cavity 11 from flowing out to the outside through the inlet of the cavity 11.

[0087] Figure 3 Observing from another direction Figure 1 The image. Figure 4 This is a bottom view of a cooking apparatus according to an embodiment.

[0088] A suction section 14 can be provided at the lower part of the main body 10 to draw in moisture, oil vapor, etc. rising from the heating and cooking device. Therefore, the cooking device can function as an exhaust hood that draws in air discharged from the heating and cooking device located below it and discharges it to the outside.

[0089] The intake section 14 and the vent 13 are configured to communicate with each other. Gases such as oil vapor flowing into the intake section 14 can be discharged to the outside through the vent 13. The vent 13 can be configured to communicate with a pipe connected to the outside.

[0090] On the other hand, the cavity 11 of the cooking device is formed to be not connected to the suction section 14 and the vent 13, so that the oil vapor and other gases flowing in from the suction section 14 will not flow into the cavity 11, and can be directly discharged to the outside of the main body 10 through the vent 13.

[0091] A bottom panel 15 is provided at the lower part of the main body 10, and the intake part 14 can be formed to communicate with the ventilation hole 13 through the bottom panel 15.

[0092] A lighting section 25 that illuminates downwards can be formed on the bottom panel 15. This lighting can be, for example, shaped to be elongated along the side of the cooking appliance. With the illumination from the lighting section 25, the user can conveniently use the heating cooking device located on the lower side of the cooking appliance.

[0093] Figure 5 This is a perspective view showing the door 20 of a cooking appliance according to an embodiment. Figure 6 Observing from another direction Figure 5 The image.

[0094] Figure 7 This is the rear view of door 20. Figure 8 This is a perspective view showing an exploded portion of a door 20 in one embodiment. Figure 9 Observing from another direction Figure 8 The image.

[0095] The door 20 may include a display module 21, a cooling flow path 22, and a shielding part 23. The display module 21 is disposed in front of the door 20, and the user can use the display module 21 to view the interior of the cavity 11 of the cooking device.

[0096] The cooling flow path 22 is disposed behind the display module 21, and an airflow path for cooling can be formed inside it. The air flowing into the door 20 can flow inside the door 20 and cool the door 20 by utilizing the cooling flow path 22.

[0097] The shielding part 23 is disposed behind the cooling flow path part 22 and can shield electromagnetic waves generated from the main body 10. The shielding part 23 can block electromagnetic waves generated from the cavity 11 and propagating to the outside of the cooking device to protect the user.

[0098] For example, shielding part 23 can block electromagnetic waves (microwaves) generated for cooking food inside the main body 10 from being emitted to the outside of door 20.

[0099] The cooling flow path 22 is provided for cooling electrical components installed inside the door 20, including the display unit 110 installed in the display module 21. Air can flow inside the cooling flow path of the cooling door 20. The display unit 110 can be formed to be thin, and its area can occupy most of one side of the door 20.

[0100] Therefore, the display unit 110 is formed to occupy most of the front area of ​​the door 20, thereby increasing the configuration area of ​​the display unit 110 and improving the user's visibility. The user can conveniently check various information using the display unit 110 with its large screen.

[0101] Because the display unit 110 is larger, the heat generation may increase. Therefore, it is necessary to configure the display unit 110 to be effectively cooled within the door 20. In an embodiment, a cooling flow path for cooling airflow may be additionally provided.

[0102] The cooling flow path 22 is positioned behind the display unit 110 and allows cooling air to flow through it, thus effectively cooling the display unit 110. Additionally, the heat-generating components mounted on the display module 21 can also be cooled by the air flowing through the cooling flow path 22. In other words, the cooling flow path 22 can cool the display module 21, which includes the display unit 110 and various other heat-generating components.

[0103] In order to effectively cool the display unit 110, the entire display unit 110 needs to be exposed to the air flowing in the cooling flow path 22. In addition, it is necessary to form an air curtain by the airflow discharged to the outside of the door 20 through the cooling flow path 22 to block the hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment.

[0104] Therefore, the air flowing in the cooling flow path 22 can be diverted inside the cooling flow path 22 to be discharged to the upper and lower sides of the display module 21.

[0105] Since the cooling air is split inside the cooling flow path 22 and discharged to the upper and lower sides of the display module 21, the cooling air can contact and flow with the entire back side of the display unit 110, thereby effectively cooling the display unit 110.

[0106] In addition, since cooling air is discharged to the upper and lower sides of the display module 21 respectively, an air curtain is effectively formed around the display and the door 20, so that hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment can be effectively blocked by the air curtain.

[0107] The display module 21 may include a display unit 110, a camera, and other electrical components, while the cooling flow path 22 may include electrical components such as a fan 150 operated by a motor. Therefore, in order to protect the user and electrical components from electromagnetic waves, a shielding part 23 that shields electromagnetic waves generated from the main body may be provided behind the cooling flow path 22.

[0108] The display module 21 may be configured with a display section 110 and various electrical components. A cooling flow path section 22, which forms a flow path for cooling the display module 21, may be configured behind the display module 21. A shielding section 23, which shields electromagnetic waves from reaching the electrical components provided on the display module 21, may be configured behind the cooling flow path section 22.

[0109] In this embodiment, the display module 21, used to provide various information and convenience to the user, needs to be positioned on the front of the cooking appliance, i.e., at the very front of the door 20. Additionally, this embodiment requires a structure that effectively cools components such as the display section 110 housed in the display module 21, and simultaneously forms a flow path for cooling air to create an air curtain around the door 20 while effectively cooling the interior of the door 20 where the display section 110 is located, and protects the electrical components installed on the door 20 from electromagnetic waves.

[0110] To meet this requirement, the display module 21 can be positioned at the front of the door 20, the cooling flow path 22 can be positioned behind the display module 21, and the shielding part 23 can be positioned behind the cooling flow path 22.

[0111] That is, in order to realize the door structure of the aforementioned embodiment, the door 20 needs to arrange the display module 21, cooling flow path section 22, and shielding section 23, which each play their respective roles, in sequence from the front to the rear of the door 20.

[0112] The display module 21 may include a first outlet 123 and a second outlet 124. The first outlet 123 may be configured on the upper part of the display module 21, and the air flowing inside the display module 21 may be discharged to the outside through the first outlet 123.

[0113] The second outlet 124 can be configured at the lower part of the display module 21, and the air flowing inside the display module 21 can be discharged to the outside through the second outlet 124. That is, the air flowing inside the door 20 can be discharged to the outside through the first outlet 123 and the second outlet 124 respectively configured at the upper and lower parts of the door 20, so that the air can flow throughout the entire interior of the door 20, thereby effectively cooling the entire door 20.

[0114] The display module 21 may include a display unit 110 and an outer panel 120. The display unit 110 may be configured on the front of the door 20 and display images, videos, or pictures.

[0115] The display unit 110 can display and provide cooking information to the user. In addition, the display unit 110 can receive user commands via touch recognition.

[0116] On the other hand, the display unit 110 can be communicatively connected to other household appliances, as well as cameras, locking devices, etc. installed on the entrance door. In addition, the display unit 110 can be communicatively connected to external devices required by the user.

[0117] Users can receive information about the operation of home appliances, visits from outsiders, and other aspects of daily life from the display unit 110, and can also use the display unit 110 to send commands to home appliances and other devices connected to the display unit 110.

[0118] Therefore, the door 20, including the display unit 110, can serve as an Internet of Things hub that transmits information about home appliances and other devices needed for daily life to users and transmits user instructions to such devices.

[0119] The outer panel 120 is disposed behind the display unit 110, and the display unit 110 can be mounted on the outer panel 120. The outer panel 120 can be generally formed into a shape having a hollow portion 1201 and a predetermined width along the front-back direction of the door 20.

[0120] The hollow portion 1201 of the outer panel 120 can be closed by the back of the display unit 110. Air flowing inside the outer panel 120 can collide with the back of the display unit 110 exposed in the hollow portion 1201 of the outer panel 120. Thus, the air flowing inside the outer panel 120 can contact the back of the display unit 110 to cool the display unit 110.

[0121] In addition, the air passing through the fan 152 can cool heat-generating components such as the speaker 260, microphone 270, and printed circuit board that are exposed and disposed in the hollow portion 1201 of the outer panel 120.

[0122] Because the outer panel 120 has the aforementioned structure, it can have an internal space in which various components can be housed. The width of the door 20 in the front-to-back direction can be almost entirely determined by the outer panel 120.

[0123] A first through-hole 121 for air inflow can be formed at the upper end of the outer panel 120. A plurality of first through-holes 121 can be provided. Each first through-hole 121 can be arranged with a plurality of slit-shaped holes spaced apart. Using this structure, external foreign objects can be slightly suppressed from flowing into the interior of the door 20 through the first through-holes 121.

[0124] A handle 122 may be provided on one side of the outer panel 120 for use by the user when opening and closing the door 20. For example, the handle 122 may be formed by a recess in the side of the outer panel 120.

[0125] A button device 300 may be installed on one side of the outer panel 120, for example, directly below the location where the handle 122 is formed. The user can operate the button device 300 to supply power to or cut off the power supply to the cooking appliance. Detailed operation of the cooking appliance can be achieved by inputting commands to the display unit 110.

[0126] The outer panel 120 can support various components such as the display unit 110, speaker 260, microphone 270, and printed circuit boards for communication or control, and can be formed with a first through hole 121 for external air to flow in, a first outlet 123 for air to be discharged, and a second outlet 124.

[0127] On the other hand, a camera can be installed in the door 20. The images captured by the camera can be played on the display unit 110, allowing the user to observe the interior of the cavity 11 or the image below the cooking appliance using the display unit 110. The camera may include at least one of a first camera 310, a second camera 210, and a third camera 230.

[0128] The first camera 310 can be configured at the upper front of the display module 21 to capture images of the front of the cooking equipment.

[0129] The first camera 310 can capture images of the user or the interior space located in front of the cooking equipment. Therefore, the first camera 310 can be used when the user uses the display unit 110 to make video calls with others at other remote locations outside the entrance door. The first camera 310 will be described in detail later.

[0130] The second camera 210 can be mounted on the lower part of the outer panel 120 and capture images of the lower part of the door 20. The second camera 210 is mounted on the lower part of the outer panel 120 so that its line of sight is directed towards the lower part of the cooking equipment, thus allowing it to capture images of the heating and cooking device located at the lower part of the cooking equipment. Alternatively, the second camera 210 can be used to monitor the status of the heating and cooking device at the lower part of the cooking equipment.

[0131] Users can use the images captured by the second camera 210 and displayed on the display unit 110 to observe the status of the heating and cooking device and the cooking status of the food in the heating and cooking device.

[0132] The third camera 230 is mounted on the frame 160 and positioned facing the cavity 11, and can capture images of the cavity 11. That is, the line of sight of the third camera 230 can be set to face the cavity 11 and capture images of the cavity 11. The user can use the images captured by the third camera 230 to observe the food cooking process in the cavity 11.

[0133] Door 20 may include a latch 250, which is mounted on the side of frame 160 and a portion of which is formed to protrude from frame 160. The latch 250 may be configured to engage with a groove formed in the front panel 12 of door 20. The latch 250 can stably hold door 20 in a closed state.

[0134] Figure 10 This is an exploded perspective view of gate 20 in one embodiment. Figure 11 Observing from another direction Figure 10 The diagram shows that the cooling flow path 22 may include an inner panel 130, an air guide 140, and an air supply device 150.

[0135] The inner panel 130 can be disposed behind and mounted on the outer panel 120. An air guide 140, described later, can be mounted on the inner panel 130. The inner panel 130 and the air guide 140 together form a space for airflow into the interior of the door 20.

[0136] Air guide 140 is mounted on inner panel 130, which can be combined with frame 160 to provide space for airflow into the interior of door 20.

[0137] Air guide 140 can be disposed between outer panel 120 and inner panel 130, and can be combined with inner panel 130. Air guide 140 can guide the flow of air flowing from the outside into the interior of door 20, and can form a space for air flow.

[0138] The air supply device 150 can be installed on the air guide 140. The air supply device 150 can force the air flowing into the air guide 140 to flow from the rear of the air guide 140 to the front.

[0139] The shielding part 23 may include a frame 160 and a blocking member 170. The frame 160 may be disposed behind and coupled to the inner panel 130, and one side thereof may be rotatably coupled to the main body 10. As the frame 160 rotates, the door 20 may rotate to open and close the cavity 11 of the cooking device.

[0140] The frame 160 can be combined with the inner panel 130 to form a flow path for cooling air while having a shielding structure, i.e., a blocking member 170, to prevent electromagnetic wave leakage, and can form the inner side of the door 20.

[0141] The blocking member 170 can be disposed behind and combined with the frame 160, and can block the electromagnetic waves generated from the main body 10 from being emitted to the outside. The blocking member 170 can generally be formed into a quadrilateral shape with a hollow portion, and can be formed into an edge portion surrounding the frame 160.

[0142] Reference Figure 2 Inside the main body 10, an electrical chamber 14 for installing various electrical and electronic components can be provided on one side of the cavity 11. The door 20 can cover the entire front of the main body 10, including the electrical chamber 14 and the cavity 11.

[0143] In contrast, the shielding part 23 can be configured as a component to suppress the propagation of electromagnetic waves such as microwaves generated in the cavity 11 into the interior of the door 20. Therefore, the shielding part 23 can be provided in the door 20 with a size, position, and shape corresponding to the cavity 11 when the door 20 is closed.

[0144] Therefore, as Figure 2 and Figure 7 As shown, the area of ​​the shielding portion 23, including the frame 160 and the blocking member 170, can be smaller than the area of ​​the door 20. Figure 7 Based on the content shown, the shielding part 23 is arranged on the lower right side of the door 20, so that it can be located in a position corresponding to the cavity 11.

[0145] Figure 12 This is a perspective view showing an embodiment of the outer panel 120. Figure 13 Observing from another direction Figure 12 The image. Figure 14 This is a diagram showing an inner panel and air guide of one embodiment. Figure 15 yes Figure 14 An exploded 3D diagram.

[0146] Reference Figure 13 The door 20 may include a speaker 260 and a microphone 270. At least one speaker 260 may be mounted on the side of the outer panel 120. The speaker 260 may generate voice, prompts, etc., required for the operation of the cooking equipment. In addition, the speaker 260 may generate all voice, prompts, etc., for enabling the door 20, including the display 110 of the door 20, to function as an Internet of Things hub.

[0147] Microphone 270 can be mounted on the lower part of the outer panel 120 and can receive user voice. Users can use microphone 270 to input voice commands for operating the cooking equipment. Additionally, microphone 270 can serve as part of enabling door 20 to function as an IoT hub.

[0148] On the other hand, a communication unit for communication can be provided in the door. Since the door 20 functions as an Internet of Things hub, the communication unit provided in the door 20 is preferably configured to perform various types of wired or wireless communication functions.

[0149] The outer panel 120 may have a first through-hole 120c and a second through-hole 120d. The first through-hole 120c may be formed on the side of the outer panel 120. The first through-hole 120c may be located near the position where the speaker 260 is disposed. The first through-hole 120c may be formed in a mesh shape to allow the speaker 260 to communicate with the outside and to prevent the speaker 260 from being exposed to the outside.

[0150] The speaker 260 communicates with the outside of the outer panel 120 via the first through-hole 120c, thereby effectively transmitting prompts and other voice messages to the user. Since there is a pair of speakers 260, the first through-hole 120c can also be a pair and formed at positions corresponding to each speaker in the pair of speakers 260.

[0151] The second through-hole 120d can be formed to penetrate the lower part of one side of the outer panel 120. A portion of the button device 300 installed inside the outer panel 120 can be exposed to the outside of the outer panel 120 through the second through-hole 120d. The user can operate the button device 300 by touching the exposed part of the outer panel 120.

[0152] A first outlet 123 may be provided on the upper part of the outer panel 120, and a second outlet 124 may be provided on the lower part. The first outlet 123 is provided on the upper part of the outer panel 120, allowing air flowing inside the door via the air supply device 150 to be discharged to the outside. The second outlet 124 is provided on the lower part of the outer panel 120, allowing air flowing inside the door via the air supply device 150 to be discharged to the outside.

[0153] The first outlet 123 can be located adjacent to the upper end of the display unit 110, and the second outlet 124 can be located adjacent to the lower end of the display unit 110. Therefore, the air forced to flow inside the door 20 by means of the air supply device 150 can be discharged to the outside from the positions adjacent to the upper and lower ends of the display unit 110 through the first outlet 123 and the second outlet 124.

[0154] Air discharged through the first outlet 123 can form an air curtain at the top of the door 20. Additionally, air discharged through the second outlet 124 can form an air curtain at the bottom of the door 20.

[0155] An air curtain is a means of blocking external airflow from penetrating into the door 20. In an embodiment, the boundary surface or boundary region where the airflow discharged from the interior of the door 20 via the first outlet 123 and the second outlet 124 forms a boundary with the external airflow can be referred to as an air curtain.

[0156] An air curtain formed by air discharged from the interior of door 20 via the first outlet 123 and the second outlet 124 can suppress the infiltration of external air into door 20.

[0157] Because the heating cooking device is located at the bottom of the cooking equipment, the heat generated when using the heating cooking device and the oil vapor from the food being cooked may rise and penetrate into the cooking equipment.

[0158] The heat transferred from the heating element to the cooking appliance may damage components located on the door 20 of the cooking appliance. In particular, the display unit 110 and components containing circuits, components, etc., related to its operation may be susceptible to heat.

[0159] Additionally, oil vapors transferred from the food being cooked may adhere to the door 20 of the cooking appliance. Oil vapors may adhere to the surface of the display unit 110, reducing its image quality, and may also adhere to the surfaces of other components mounted on the door 20, potentially damaging them.

[0160] In an embodiment, the airflow discharged to the outside of the door 20 via the first outlet 123 and the second outlet 124 provided on the door 20 can form an air curtain, which can effectively block the hot air and oil vapor rising from the heating cooking device located at the bottom of the cooking equipment.

[0161] Therefore, it is possible to effectively prevent various electronic components, including the display unit 110, installed on the door 20 from being damaged or having their functions reduced due to hot air and oil vapor.

[0162] Reference Figure 14 The air guide 140 may include an inlet 141 and an outlet 142. The inlet 141 may be configured on the upper part of the air guide 140 to allow outside air to flow in, and at least one inlet 141 may be provided.

[0163] The inlet 141 can be configured at a position corresponding to the first through hole 121 provided on the upper part of the outer panel 120. Therefore, external air can flow into the interior of the door 20 through the first through hole 121 of the outer panel 120 and through the inlet 141.

[0164] An exhaust port 142 is formed at the lower part of the inlet 141 in the air guide 140, and a blower fan 152 can be arranged at a position that overlaps with the exhaust port 142 in the front-back direction. The exhaust port 142 can be formed to penetrate the air guide 140 in the front-back direction of the door 20.

[0165] Therefore, air can flow from the upper part to the lower part of the air guide 140 through the inlet 141, and then change direction to flow from the rear to the front of the air guide 140 through the exhaust port 142.

[0166] The air supply device 150 may include a housing 151 and an air supply fan 152. The housing 151 may be disposed at the exhaust port 142 and form a hollow portion, in which the air supply fan 152 may be installed.

[0167] The blower fan 152 is rotatably mounted on the housing 151 and allows air to flow from the rear of the air guide 140 to the front. The blower fan 152 can be powered to rotate, thereby causing air to flow inside the door 20.

[0168] With the help of the rotation of the blower fan 152, outside air can flow into the interior of the door 20 through the inlet 141 and can be discharged to the outside of the door 20 through the first outlet 123 and the second outlet 124. The exhaust port 142 of the air guide 140 is formed in the center of the housing 151 and can be formed to correspond to the position, area and shape of the hollow part in which the blower fan 152 is disposed.

[0169] Figure 16 Is Figure 5 The side sectional view of door 20 in the 16-16 direction is observed below. (Refer to the following text.) Figure 16 This specifically describes the airflow inside door 20. Figure 16 In the image, arrows are used to represent the flow of air.

[0170] As the blower fan 152 rotates, outside air can flow into the interior of the door 20 through the inlet 141 of the air guide 140, and can be discharged to the outside of the door 20 through the first outlet 123 and the second outlet 124.

[0171] Specifically, the air forced to flow by the blower fan 152 can have the following flow path.

[0172] Air can flow into the interior of the door 20 through the first through hole 121 of the outer panel 120 and the inlet 141 located thereto. The air flowing into the interior of the door 20 can flow downward toward the door 20 and into the blower fan 152.

[0173] Air can pass through the fan 152 in the front-to-back direction of the door 20. At the same time, air can pass through the exhaust port 142 of the air guide 140 while passing through the fan 152. The airflow direction can be changed from the vertical direction of the door 20 to the front-to-back direction by the fan 152.

[0174] Since the front of the exhaust port 142 is blocked by the display unit 110, the air passing through the exhaust port 142 can be diverted in the vertical direction in front of the air guide 140.

[0175] A portion of the diverted air can flow upward toward the door 20 and exit from the first outlet 123. Another portion of the diverted air can flow downward toward the door 20 and exit from the second outlet 124.

[0176] The air diverted from the first row of outlets 123 and the second row of outlets 124 can surround the entire door 20. In particular, the diverted air can surround the front part of the door 20. With this structure, the air discharged from the first row of outlets 123 and the second row of outlets 124 forms an air curtain in the door 20, thereby effectively suppressing the penetration of hot air and oil vapor generated from the heating cooking device located at the bottom of the cooking equipment into the door 20.

[0177] Furthermore, utilizing the aforementioned structure that allows air to flow inside the door 20, the air flowing into the door 20 can circulate throughout the entire interior of the door 20. For example, air can circulate throughout the entire space formed by the back of the display unit 110 and the outer panel 120.

[0178] Thus, the air flowing inside the door 20 can cool the entire back of the display unit 110, and can effectively cool the outer panel 120 and other components installed on other parts of the door 20.

[0179] In particular, heat-generating components such as a speaker 260, a microphone 270, and a printed circuit board can be installed on the outer panel 120. Such heat-generating components can be distributed throughout the entire outer panel 120. Therefore, air can effectively cool such heat-generating components while flowing throughout the entire interior of the outer panel 120.

[0180] like Figure 16 As shown, the first through-hole 121 and the inlet 141 for air inflow can be connected to each other. As the blower fan 152 rotates, external air can flow into the interior of the air guide 140 through the first through-hole 121 and the inlet 141, and can flow toward the blower device 150 through the space formed by the inner panel 130 and the air guide 140.

[0181] Air can flow from the space formed by the frame 160 toward the air supply fan 152 of the air supply device 150. The air can pass through the air supply fan 152 and collide with the back of the display unit 110 which is arranged facing the air supply fan 152, thereby cooling the display unit 110.

[0182] After passing through the fan 152 and colliding with the back of the display unit 110, the airflow can be split in the upward and downward directions of the display unit 110. The air flowing towards the upper side of the display unit 110 can be discharged to the outside of the door 20 through the first outlet 123 provided on the upper side of the outer panel 120. The air flowing towards the lower side of the display unit 110 can be discharged to the outside of the door 20 through the second outlet 124 provided on the lower side of the outer panel 120.

[0183] In this embodiment, the air flowing inside the door 20 can cool the entire front of the display unit 110 while being discharged through the first outlet 123. Additionally, the air flowing inside the door 20 can effectively cool the back of the display unit 110 and the heat-generating components installed inside the door 20.

[0184] An exhaust port 142 may be formed in the center of the air guide 140. The housing 151 may have a hollow portion corresponding to the position, size, and shape of the exhaust port 142, and a blower fan 152 may be disposed in the hollow portion. The housing 151 may be configured to be placed at a position corresponding to the exhaust port 142 of the air guide 140, and may be mounted on one side of the air guide 140.

[0185] A hollow portion 130a may be formed in the inner panel 130. Since the hollow portion 130a of the inner panel 130 is blocked by the frame 160, the air flowing in through the inlet 141 can not leak from the hollow portion 130a of the inner panel 130. Therefore, the inner panel 130 and the frame 160 can together form an airflow path for the air to flow inside the cooling door 20.

[0186] Figure 17 It is Figure 16 The diagram shows an enlarged view of part 17. The door 20 may include a front joint 24, which is disposed above the display unit 110 and protrudes towards the front of the door 20, and is attached to the outer panel 120. A gap of a predetermined size is formed between the lower part of the front joint 24 and the front of the display unit 110, which serves as a passage for the exhaust of air from the interior of the cooling door 20.

[0187] The front joint 24 may include a detection module 310 and a panel 320. The detection module 310 is disposed at the upper front of the display module 21, detects external conditions, and may have various detection devices.

[0188] The panel portion 320 can be disposed on the upper front of the display module 21. The panel portion 320 can be configured to cover the detection module 310. Since the panel portion 320 covers the detection module 310, the panel portion 320 can form the shape of the front joint portion 24. In this case, the detection module 310 can be accommodated inside the panel portion 320.

[0189] In another embodiment, the detection module 310 may also be configured behind the panel portion 320, rather than being housed inside the panel portion 320.

[0190] The panel portion 320 can be configured to overlap with the display module 21. As another embodiment, the panel portion 320 can also be configured on the upper side of the display module 21 without overlapping with the display module 21.

[0191] The panel portion 320 may protrude further forward than the display module 21. As another embodiment, the panel portion 320 may also be configured such that its front surface is on the same plane as the front surface of the display module 21, or is located further rearward than the front surface of the display module 21, without protruding relative to the display module 21.

[0192] The panel portion 320 can be formed into a rod shape that is generally long and arranged along the side of the door 20 in its length direction. The panel portion 320 can guide the flow direction of the air discharged from the first outlet 123. For example, the panel portion 320 can change the flow direction of the air discharged from the first outlet 123 to the downward direction.

[0193] For this purpose, the panel portion 320 can be positioned in front of the first row of outlets 123. The panel portion 320 can be configured to overlap with the first row of outlets 123 in the front-rear direction. Air flowing inside the door 20 can be discharged in the front direction of the door 20 through the first row of outlets 123 located at the upper part of the door 20.

[0194] At this time, the panel 320 blocks the front of the first row outlet 123, and the air discharged from the first row outlet 123 is blocked by the panel 320, so the flow direction can be changed from the front direction of the door 20 to the downward direction.

[0195] Furthermore, the lower end of the panel portion 320 can be configured to protrude further downward than the lower end of the first outlet 123. With this structure, the air discharged from the first outlet 123 collides with the panel portion 320 and is guided by the panel portion 320, thereby changing the flow path downward.

[0196] The air discharged from the first outlet 123 in the forward direction can flow downward through the panel 320.

[0197] Air discharged forward from the first outlet 123 collides with the back of the panel 320, thereby changing its direction and flowing towards the open lower portion between the panel 320 and the first outlet 123. Furthermore, since the lower end of the panel 320 protrudes further downward than the lower end of the first outlet 123, air can be guided by the lower end of the panel 320 and then continue to flow downward towards the door 20 for a period of time after leaving the door 20.

[0198] Air forced to flow by the fan 152 can flow in from the inlet 141 and flow downwards into the fan 152. It then flows along the front-back direction of the door 20 through the fan 152 and splits in the vertical direction in front of the air guide 140. Part of the air flows upwards into the door 20 and is discharged from the first outlet 123, while the other part flows downwards into the door 20 and is discharged from the second outlet 124.

[0199] At this time, the air discharged from the first row outlet 123 is guided by the panel portion 320 to flow downwards, so that at least a portion can contact the front of the display portion 110. In addition, at least a portion of the air discharged from the second row outlet 124 can flow towards the front of the door 20.

[0200] The air discharged from the second outlet 124 flows in front of the door 20, thereby preventing the oil vapor and other foreign objects rising from the heating cooking device located below the cooking equipment from adhering to the air curtain on the front of the display unit 110.

[0201] Similar to the air discharged from the second outlet 124, the air discharged from the first outlet 123 can form an air curtain to prevent oil vapor and the like from adhering to the front of the display unit 110.

[0202] In addition, the airflow direction discharged from the first row outlet 123 can be changed by the panel 320 to be discharged towards the lower side of the door 20, so that at least a part of it can come into contact with the front of the display 110.

[0203] With this structure, the air discharged from the first row outlet 123 can directly contact the front of the display unit 110 to cool the front of the display unit 110. Therefore, both the front and back of the display unit 110 are cooled by air, thereby significantly improving cooling efficiency compared to the case where only the back of the display unit 110 is cooled.

[0204] Figure 18 This is an exploded perspective view showing a portion of the components of door 20. An inner panel 130 may be disposed behind the outer panel 120. An air guide 140 may be disposed in front of the inner panel 130. Therefore, the air guide 140 is disposed between the outer panel 120 and the inner panel 130 and can be coupled to both the outer panel 120 and the inner panel 130. On the other hand, a blocking member 170 may be disposed behind the inner panel 130 and coupled to the outer panel 120.

[0205] In this embodiment, the outer panel 120 may form the shape of the door 20. A large space for accommodating other components may be formed on the inner side of the outer panel 120, and the air guide 140 may be accommodated in such a space.

[0206] In addition, an air guide 140, an inner panel 130, and a blocking member 170 may be integrated into the outer panel 120. In order to ensure that these components integrated into the outer panel 120 can be stably configured and connected, various connection means and mounting structures need to be provided on the outer panel 120.

[0207] Hereinafter, with reference to the accompanying drawings, a structure that enables the air guide 140, inner panel 130, and blocking member 170 to be stably attached to the outer panel 120 will be described in detail.

[0208] Figure 19 This is a rear view of the outer panel 120 of one embodiment. Figure 20 It is Figure 19 The 20 enlarged 3D images are shown. Figure 21 It is Figure 19 The 21 enlarged 3D images are shown. Figure 22 It is Figure 19 The 22 enlarged 3D images are shown.

[0209] A first mounting protrusion 126 may be formed on the outer panel 120. The first mounting protrusion 126 is formed on the inner side of the outer panel 120 at the edge of the outer panel 120. The end of the inner panel 130 is disposed on the first mounting protrusion 126. A plurality of first mounting protrusions 126 may be provided spaced apart from each other.

[0210] For the outer panel 120 and the inner panel 130 to be joined, a first mounting protrusion 126 may be formed on the outer panel 120. The end of the inner panel 130 is inserted into the first mounting protrusion 126, so that the inner panel 130 can be stably joined to the outer panel 120.

[0211] The first mounting protrusion 126 may include a first base 1261 and a first groove forming protrusion 1262. The first base 1261 may protrude from the inner surface of the edge of the outer panel 120.

[0212] The first groove forming protrusion 1262 can protrude rearward from the first base 1261. The first groove forming protrusion 1262 can be separated from the inner surface of the outer panel 120 to form a groove for the end of the inner panel 130 to be placed.

[0213] The end of the inner panel 130 can be bent from the edge of the inner panel 130. The bent end of the inner panel 130 can be inserted into the groove of the first placement protrusion 126 formed by the first groove forming protrusion 1262.

[0214] With this structure, if the end of the inner panel 130 is inserted into the first mounting protrusion 126 of the outer panel 120, the inner panel 130 can be stably attached to the outer panel 120 without detaching from its designed position.

[0215] A plurality of first mounting protrusions 126 may be provided at the bent portion of the edge of the outer panel 120. Thus, the plurality of first mounting protrusions 126 stably support the end of the outer panel 120, thereby allowing the inner panel 130 to be stably attached to the outer panel 120 and to maintain this attachment state and position.

[0216] The outer panel 120 may include a front panel 120a and sidewalls 120b, an upper end wall 120e, and a lower end wall 120f formed by bending from the front panel 120a. A display unit 110 may be attached to the front panel 120a. The sidewalls 120b may be bent rearward from both sides of the front panel 120a. A first mounting protrusion 126 may protrude from the inner surface of the sidewall 120b.

[0217] The upper end wall 120e can be bent rearward from the upper end of the front panel 120a. The first mounting protrusion 126 can protrude from the inner surface of the upper end wall 120e. The lower end wall 120f can be bent rearward from the lower end of the front panel 120a. The first mounting protrusion 126 can protrude from the inner surface of the lower end wall 120f.

[0218] The first mounting protrusion 126 can be arranged in a plurality of spaces between each of the side wall 120b, upper wall 120e, and lower wall 120f of the outer panel 120, thereby stably supporting the inner panel 130.

[0219] In this embodiment, the inner panel 130 can be stably attached to the outer panel 120 by forming a plurality of first mounting protrusions 126 on the inner sidewall of the outer panel 120. Therefore, the inner panel 130 can maintain its designed position. Thus, even under external impact, the inner panel 130 will not detach from its designed position. This improves the assemblability of the outer panel 120 and the inner panel 130.

[0220] Figure 23 It is Figure 19 The 23 enlarged 3D images are shown. Figure 24 It is Figure 19 The 24 enlarged 3D images are shown. Figure 25 It is Figure 19 The 25 enlarged 3D images are shown. Figure 26 It is Figure 19 The 26 enlarged 3D images are shown. Figure 27a It is Figure 19 The 27 parts are enlarged 3D images.

[0221] The blocking member 170 can be disposed behind the inner panel 130. The blocking member 170 can be coupled to the outer panel 120. In order to enable the coupling between the blocking member 170 and the outer panel 120, a second mounting protrusion 127 can be provided on the outer panel 120.

[0222] A pair of sidewalls 120b may be provided, respectively formed on both sides of the front panel 120a. A second mounting protrusion 127 may be formed on either sidewall of the pair of sidewalls 120b. The second mounting protrusion 127 is formed on the inner side of the sidewall 120b. The end of the blocking member 170 is disposed on the second mounting protrusion 127, and a plurality of second mounting protrusions 127 are spaced apart from each other.

[0223] The second mounting protrusion 127 may include a second base 1271 and a second groove forming protrusion 1272. The second base 1271 may protrude from the inner surface of the sidewall 120b. The second groove forming protrusion 1272 may protrude from the second base 1271 in a rearward direction and be spaced apart from the inner surface of the sidewall 120b to form a groove for mounting the end of the blocking member 170.

[0224] The end of the blocking member 170 can be bent from the edge of the blocking member 170. The bent end of the blocking member 170 can be inserted into the groove of the second placement protrusion 127 formed by the second groove forming protrusion 1272.

[0225] With this structure, if the end of the blocking member 170 is inserted into the second mounting protrusion 127 of the outer panel 120, the blocking member 170 can be stably attached to the outer panel 120 without detaching from its designed position.

[0226] A plurality of second mounting protrusions 127 may be provided at the bent portion of the edge of the outer panel 120. Thus, the plurality of second mounting protrusions 127 stably support the end of the outer panel 120, thereby allowing the blocking member 170 to be stably attached to the outer panel 120 and to maintain this attachment state and position.

[0227] In this embodiment, the blocking member 170 can be stably attached to the outer panel 120 via a plurality of second mounting protrusions 127 formed on the inner sidewall of the outer panel 120. Therefore, the blocking member 170 can maintain its designed position. Thus, even under external impact, the blocking member 170 will not detach from its designed position. This improves the assemblability of the outer panel 120 and the blocking member 170.

[0228] On the other hand, in the outer panel 120, the second mounting protrusion 127 can be positioned further rearward than the first mounting protrusion 126. Since the blocking member 170 is positioned behind the inner panel 130, the second mounting protrusion 127, which is coupled to the blocking member 170, can be positioned further rearward than the first mounting protrusion 126, which is coupled to the inner panel 130.

[0229] A handle 122, which is recessed from the outside to the inside, may be provided on the side wall 120b of the outer panel 120. By forming a protrusion on the side wall 120b where the handle 122 is formed, which is shorter than the first placement protrusion 126, it is possible to prevent the handle 122 and the protrusion from overlapping.

[0230] Therefore, the outer panel 120 may include a first set of mounting protrusions 126a protruding from the inner edge of the handle 122 and the inner surface of the side wall 120b. A plurality of the first set of mounting protrusions 126a may be provided spaced apart from each other.

[0231] Except for being shorter in length than the first mounting protrusion 126, the first mounting protrusion 126a is formed with a structure similar to the first mounting protrusion 126, which can stably mount the end of the inner panel 130.

[0232] To stably secure the outer panel 120 and the inner panel 130, a hook-and-loop structure may be provided on the outer panel 120 and the inner panel 130. The outer panel 120 may include a first hook protrusion 128 protruding from the inner surface of its edge.

[0233] Correspondingly, the inner panel 130 may include a hook insertion hole 131, which is formed through the inner panel 130 at a position corresponding to the first hook protrusion 128 on the edge of the inner panel 130, and the first hook protrusion 128 is inserted into the hook insertion hole 131.

[0234] The first hook protrusion 128 can be formed on at least one of the side wall 120b, the upper end wall 120e, and the lower end wall 120f. Of course, the hook insertion holes 131 can also be provided in a corresponding number at positions corresponding to the first hook protrusion 128. Therefore, the outer panel 120 and the inner panel 130 can be stably joined together.

[0235] By using the first hook protrusion 128 and the hook insertion hole 131 to fix the outer panel 120 and the inner panel 130 to each other, the outer panel 120 and the inner panel 130 can be more firmly joined together with the aforementioned placement protrusion.

[0236] Figure 27b It is shown Figure 7 A diagram of the upper part of the cross-section of section 27b-27b. Figure 27c It is Figure 27b A magnified portion of the image. Figure 27d It is Figure 27b Another enlarged portion of the image.

[0237] like Figures 27b to 27d As shown, the inner panel 130 and the blocking member 170 can be arranged spaced apart from each other along the front-back direction at the edges and placed on the outer panel 120.

[0238] Such a mounting structure can be configured such that the blocking member 170 and the inner panel 130 overlap in the front-rear direction of the door 20, and the blocking member 170 and the inner panel 130 are provided when the edge of the door 20 is joined to the outer panel 120.

[0239] This is because, as mentioned above, since the area of ​​the shield 23 with the blocking member 170 disposed at the edge is smaller than the overall area of ​​the door 20, the blocking member 170 and the inner panel 130 will not overlap along the front-back direction of the door 20 at the entire edge of the door 20.

[0240] For example, refer to Figure 7 In region A1, which is part of the lower end wall of the outer panel 120, and region A2, which is a side wall 120b of the outer panel 120, the blocking member 170 and the inner panel 130 can be simultaneously disposed on the outer panel 120.

[0241] The following describes the structure in which the blocking member 170 and the inner panel 130 are joined to the side wall 120b of the outer panel 120 in region A2. The joining structure in region A1 is substantially the same as described below, so a repetition of the description is omitted.

[0242] The blocking member 170 can be disposed on the edge of the frame 160. The frame 160 can be joined to the blocking member 170 at the edge of the blocking member 170 by form fit, and can be joined to the inner panel 130 by a joining mechanism 1000 such as screws.

[0243] At this time, the inner panel 130 can be positioned in front of the frame 160, and the blocking member 170 can be positioned behind the frame 160. Thus, the inner panel 130 and the blocking member 170 can be spaced apart from each other along the front-rear direction of the door 20 via the frame 160. The inner panel 130 can be positioned in front, and the blocking member 170 can be positioned behind.

[0244] The inner panel 130 may include a first bent portion 138 at its end, which is bent and disposed on the first mounting protrusion 126. Therefore, the first bent portion 138 may be disposed on the first mounting protrusion 126 and engaged with the first groove forming protrusion 1262 of the first mounting protrusion 126 to stably attach to the side wall 120b of the outer panel 120.

[0245] Additionally, a hook insertion hole 131 is formed in a portion of the first bend 138, and the first hook protrusion 128 is inserted into the hook insertion hole 131, so that the inner panel 130 and the outer panel 120 can be more stably joined.

[0246] The blocking member 170 may include a second bent portion 171 at its end, which is bent and disposed on the second mounting protrusion 127. Therefore, the second bent portion 171 may be disposed on the second mounting protrusion 127 and engaged with the second groove-forming protrusion 1272 of the second mounting protrusion 127 to stably attach to the side wall 120b of the outer panel 120.

[0247] With the aforementioned structure, the inner panel 130 and the blocking member 170 can be combined with the outer panel 120 at positions where they overlap in the front-back direction of the door 20.

[0248] On the other hand, when the inner panel 130 and the outer panel 120 are joined at the edge of the door 20 where the blocking member 170 is not provided, the inner panel 130 and the outer panel 120 are not joined using a joining mechanism, so they cannot be joined tightly, and the first bend 138 and the first mounting protrusion 126 may move relative to each other.

[0249] Due to this possibility of movement, even when the door 20 is assembled, the inner panel 130 and the outer panel 120 may sway relative to each other.

[0250] However, in the embodiments, as previously described, compared to the case where only the inner panel 130 and the outer panel 120 are combined, by combining the inner panel 130 and the blocking member 170 with the outer panel 120 simultaneously to overlap in the front-back direction of the door 20 in the A1 and A2 regions, the inner panel 130, the blocking member 170 and the outer panel 120 can be combined more compactly, and the possibility of movement between them can be significantly reduced.

[0251] In this embodiment, in a portion of the edge of the door 20, the inner panel 130 and the blocking member 170 can be combined with the outer panel 120 respectively in an overlapping state along the front-back direction of the door 20. This significantly reduces the mobility between the inner panel 130, the blocking member 170, and the outer panel 120, thus effectively suppressing the swaying of the inner panel 130 and the outer panel 120 relative to each other when the door 20 is assembled. This improves the operational performance of the door 20.

[0252] Figure 28a This is a front view showing the inner panel 130 and the air guide 140 in a combined state according to an embodiment.

[0253] The aforementioned first mounting protrusion 126, first secondary mounting protrusion 126a, first hook protrusion 128, and hook insertion hole 131 play a significant role in ensuring the outer panel 120 and inner panel 130 are joined together and maintained in their designed positions. Simultaneously, the outer panel 120 and inner panel 130 are joined by the joining mechanism, which provides a more secure connection between them.

[0254] Therefore, the front panel 120a may include a first fastening protrusion 120a1, which protrudes from the back of the front panel 120a toward the inner panel 130. A screw or other fastening mechanism is fastened to the first fastening protrusion 120a1, thereby engaging the first fastening protrusion 120a1 with the inner panel 130. A plurality of first fastening protrusions 120a1 may be provided.

[0255] Correspondingly, the inner panel 130 may include fastening holes 132, which are formed at positions corresponding to the first fastening protrusion 120a1 and are fastened to the first fastening protrusion 120a1 by a coupling mechanism. The fastening holes 132 may be provided in a number corresponding to the number of the first fastening protrusion 120a1.

[0256] If the coupling mechanism is fastened to the first fastening protrusion 120a1 and the fastening hole 132, the outer panel 120 and the inner panel 130 can be firmly coupled together in a way that fixes them to each other.

[0257] The outer panel 120 may include a first insertion protrusion 120a2 for holding the position of the air guide 140. The first insertion protrusion 120a2 may protrude from the back of the outer panel 120 toward the air guide 140 and may be inserted into an insertion slot 140a formed in the air guide 140.

[0258] Correspondingly, an insertion groove 140a can be formed on the air guide 140 at a position corresponding to the first insertion protrusion 120a2. A plurality of first insertion protrusions 120a2 and insertion grooves 140a can be provided.

[0259] If the air guide 140 is disposed between the outer panel 120 and the inner panel 130 and assembled with each other, the first insertion protrusion 120a2 of the outer panel 120 can be inserted into the insertion slot 140a of the air guide 140. Thus, the position between the air guide 140 and the outer panel 120 can be in the designed position, and this positional relationship can be stably maintained; the air guide 140 will not detach from the designed position.

[0260] The air guide 140 may come out of position during assembly, but such disengagement can be effectively suppressed by inserting the first insertion protrusion 120a2 into the insertion groove 140a.

[0261] Figure 28b It shows that it has been omitted. Figure 28a A diagram showing the state of the air guide 140. Figure 29 It is Figure 28b The 29 parts are enlarged 3D images. Figure 30 It is Figure 28b The 30 enlarged 3D images are shown.

[0262] like Figure 28b As shown, the inner panel 130 may include a guide piece 133, which protrudes from the front of the inner panel 130 toward the air guide 140 and is covered by the air guide 140 to guide the flow of air.

[0263] The length of the guide piece 133 can generally be arranged along the vertical direction of the inner panel 130, but a portion can be arranged in a direction that is slightly inclined to the vertical direction of the inner panel 130.

[0264] A hollow portion is formed in the inner panel 130, and a plurality of guide pieces 133 are arranged around the hollow portion and spaced apart from each other. A plurality of guide pieces 133 may be arranged spaced apart from each other along the lateral direction of the inner panel 130.

[0265] The guide plate 133 can be configured in the flow space inside the air guide 140 formed by the combination of the air guide 140 and the inner panel 130, and guide the flow of air.

[0266] The plurality of guide plates 133 are spaced apart and aligned, especially suppressing the formation of vortexes in the flow space inside the air guide 140, thereby enabling smooth airflow.

[0267] Hereinafter, with reference to the accompanying drawings, the structure in which the air guide 140 and the inner panel 130 are joined together will be described in detail.

[0268] Figure 31 It is Figure 28b The 31 enlarged 3D images are shown. Figure 32 It is Figure 28b The 32 enlarged 3D images are shown. Figure 33 It is Figure 28b The 33 parts are enlarged stereoscopic images. Figure 34 It is Figure 28b The 34 parts are enlarged stereoscopic images.

[0269] Various protrusions may be formed on the front side of the inner panel 130 to position the air guide 140 in a designed location. The lower and side ends of the air guide 140 may be bent and positioned and / or joined to the protrusions formed on the inner panel 130.

[0270] The inner panel 130 may include at least one of a first guide protrusion 134 and a second guide protrusion 135. The first guide protrusion 134 may protrude from the front of the inner panel 130 and is disposed at a position corresponding to the lower corner of the air guide 140, which guides the placement of the corner of the air guide 140.

[0271] The first guide protrusion 134 is, for example, formed in an L-shape, and the corners of the air guide 140 can be positioned on the first guide protrusion 134. Thus, the air guide 140 can be configured in a designed position relative to the inner panel 130.

[0272] The first guide protrusion 134 may be provided in pairs corresponding to a pair of lower edges of the air guide 140. The pair of first guide protrusions 134 may be formed in a shape that is symmetrical to each other with reference to the center of the inner panel 130.

[0273] The second guide protrusion 135 can protrude from the front of the inner panel 130. A pair of second guide protrusions 135 can be provided at positions corresponding to the two side edges of the air guide 140. The second guide protrusions 135 can guide the configuration position of the two side edges of the air guide 140.

[0274] The second guide protrusion 135 can be configured vertically along its length. A pair of second guide protrusions 135 can support both sides of the air guide 140. The second guide protrusions 135 can guide the air guide 140 to be positioned relative to the inner panel 130 as designed.

[0275] On the other hand, such as Figure 28b As shown, a U-shaped protrusion may also be selectively provided on the inner panel 130. The U-shaped protrusion protrudes from the front of the inner panel 130 and is formed into a U-shape corresponding to the edge of the air guide 140, guiding the configuration position of the air guide 140.

[0276] The inner panel 130 may include at least one of a third mounting protrusion 136 and a second hook protrusion 137. The third mounting protrusion 136 protrudes from the front of the inner panel 130 and its end is bent upward, and the lower end of the air guide 140 may be mounted on the third mounting protrusion 136.

[0277] A plurality of third mounting protrusions 136 may be disposed between and spaced apart from a pair of first guide protrusions 134. The lower end of the air guide 140 is inserted into the third mounting protrusion 136 and thus can be supported by the third mounting protrusion 136. The third mounting protrusion 136, together with the first guide protrusions 134, can guide the positioning of the lower edge of the air guide 140.

[0278] The second latch protrusion 137 can protrude from the front of the inner panel 130. A pair of second latch protrusions 137 can be provided at positions corresponding to the two side edges of the air guide 140. The second latch protrusions 137 can engage the air guide 140 and the inner panel 130.

[0279] On the other hand, a hole for engaging the second hook protrusion 137 can be formed at the bent end of the air guide 140 at a position corresponding to the second hook protrusion 137.

[0280] The second hook protrusion 137 engages with the hole in the air guide 140, allowing the air guide 140 to be attached to the inner panel 130 without the need for additional fastening mechanisms such as screws. Therefore, assembling the air guide 140 and the inner panel 130 becomes easier.

[0281] In an embodiment, at least one of a first guide protrusion 134, a second guide protrusion 135, a third mounting protrusion 136, and a second hook protrusion 137 may be provided on the inner panel 130. The air guide 140 is disposed and / or engaged with such protrusions, thereby allowing it to be engaged with the inner panel 130 at a designed position. This facilitates the assembly of the inner panel 130 and the air guide 140.

[0282] As described above, the present invention has been illustrated with reference to the accompanying drawings. However, the present invention is not limited to the embodiments and drawings disclosed in this specification, and it is obvious that those skilled in the art can make various modifications within the scope of the technical concept of the present invention. Furthermore, even when the embodiments of the present invention are described above, the effects of the configuration according to the present invention are not explicitly stated, but the effects that can be predicted through the corresponding configuration should be recognized.
