DETAILED DESCRIPTION

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0031] The terms "a", "an", "the", "" are used to indicate that there are one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.

[0032] The present invention provides a door structure 200 for a kitchen appliance. The kitchen appliance of the present invention is a box-type appliance for steaming and / or baking food. In a specific implementation, the kitchen appliance of the present invention can be a steamer, an oven, or a steam oven. Figure 5 The kitchen device of an embodiment of the present invention includes a cavity assembly 100 and a door structure 200. The cavity assembly 100 encloses a cooking cavity 300 with an open side. The door structure 200 is connected to the open side of the cavity assembly 100 to open or close the cooking cavity 300.

[0033] See also Figures 1 to 4The door structure 200 of the present embodiment includes a door assembly 210, a camera 220, and a cooling fan 230. The door assembly 210 includes an inner door glass 211, a middle glass 212, and an outer door glass 213 connected together. A first cavity 217 is formed between the inner door glass 211 and the middle glass 212, and a second cavity 218 is formed between the middle glass 212 and the outer door glass 213. The inner door glass 211, the middle glass 212, and the first and second cavities 217 and 218 prevent heat from being transferred out of the kitchen equipment. The door assembly 210 has an air inlet 216 and an air outlet 215. The air outlet 215 and the air inlet 216 are respectively connected to the first cavity 217. Cool air can enter the first cavity 217 from the air inlet 216 and be discharged from the air outlet 215, thereby cooling the camera 220 located in the first cavity 217 and preventing the camera 220 from overheating in its operating environment. Due to the obstruction of the inner door glass 211 , the first cavity 217 and the middle glass 212 , the temperature in the second cavity 218 can be kept relatively low, thereby meeting the working requirements of the camera 220 .

[0034] Alternatively, the air outlet 215 and the air inlet 216 can be respectively connected to the second cavity 218. Cold air can enter the second cavity 218 from the air inlet 216 and be discharged from the air outlet 215, thereby removing heat from the second cavity 218 and cooling the camera 220 to prevent the operating environment temperature of the camera 220 from being too high.

[0035] Alternatively, the air outlet 215 and the air inlet 216 are respectively connected to the first cavity 217 and the second cavity 218. The cold air entering through the air inlet 216 can pass through the first cavity 217 and the second cavity 218 before being discharged through the air outlet 215, thereby cooling the first cavity 217, the second cavity 218, and the camera 220, thereby preventing the operating environment temperature of the camera 220 from being too high.

[0036] In the embodiment of the present invention, the middle glass 212 is provided with an avoidance hole 2121. The camera 220 is arranged on the outer door glass 213, so that the camera 220 can be kept as far away as possible from the high-temperature area inside the kitchen equipment. The camera 220 extends into the first cavity 217 through the avoidance hole 2121. The avoidance hole 2121 is formed on the middle glass 212 at a position opposite to the camera 220, so that the camera 220 can extend into the first cavity 217 through the avoidance hole 2121. The camera 220 can utilize the first cavity 217 and the second cavity 218 at the same time. Compared with occupying only the first cavity 217 or the second cavity 218, the overall thickness of the door assembly 210 can be reduced, and the space occupied can be reduced. The obstruction of the middle glass 212 is reduced in front of the camera 220, which reduces the influence of the glass on the door assembly 210 on the imaging effect.

[0037] The cooling fan 230 is disposed between the inner door glass 211 and the outer door glass 213, and is located near the air inlet 216. The cooling fan 230 can input cold air through the air inlet 216, causing the cold air to flow through at least the first cavity 217 and / or the second cavity 218, and then be discharged through the air outlet 215, removing heat.

[0038] In this embodiment of the present invention, the inner door glass 211 and the middle glass 212 are double-layered for insulation, which can gradually reduce the temperature within the second cavity 218 and reduce the impact of the high temperature of the kitchen equipment on the camera 220. The middle glass 212 has an escape hole 2121, allowing the camera 220 to extend through the escape hole 2121 into the first cavity 217. The camera 220 can occupy both the first cavity 217 and the second cavity 218, thereby reducing the overall thickness of the door structure 200 and reducing the space occupied by the door structure 200. Furthermore, a cooling fan 230 allows cold air to flow through the first cavity 217 and / or the second cavity 218, removing heat and cooling the camera 220, thereby preventing the ambient temperature of the camera 220 from being too high.

[0039] See also Figure 3 and Figure 5 A handle 240 is also provided on the outer door glass 213 .

[0040] In some embodiments, the side of the middle glass 212 facing the inner door glass 211 is coated with a heat-insulating film. The heat-insulating film can enhance the heat-insulating effect of the middle glass 212 and prevent the temperature in the second cavity 218 from being too high. The heat-insulating film can be provided on the side of the middle glass 212 close to the inner door glass 211. In a specific implementation, the heat-insulating film can be a LOW-E film or other high-temperature resistant heat-insulating film. The LOW-E film can reflect part of the heat to prevent all the heat from being concentrated inside the door body assembly 210. Since the middle glass 212 is provided with an avoidance hole 2121, the camera 220 extends into the first cavity through the avoidance hole 2121, which can prevent the heat-insulating film from affecting the imaging effect of the camera 220.

[0041] In some embodiments, see Figure 2 The surface of the inner door glass 211 has an ink layer, and an observation window 2111 is opened on the ink layer. The user can directly observe the situation in the cooking cavity 300 through the observation window 2111.

[0042] In some embodiments, see Figure 2 The ink layer is provided with a camera window 2112, which is opposite to the camera 220. The camera 220 can shoot the cooking cavity 300 through the camera window 2112 to avoid affecting the imaging effect.

[0043] In some embodiments, see Figure 2The air outlet 215 is arranged above the door body assembly 210, and the air inlet 216 is arranged below the door body assembly 210. The cold air enters from the air inlet 216 below the door body assembly 210, passes through the first cavity 217, or also passes through the second cavity 218, and is discharged from the air outlet 215 above the door body assembly 210. The cold air flows from bottom to top, can better take away heat, and improves the heat dissipation effect.

[0044] In some embodiments, referring to Figure 1 and Figure 2 The door body assembly 210 further comprises a frame structure 214, two sides of the frame structure 214 are connected with the outer door glass 213 and the inner door glass 211 respectively, and a containing cavity 2140 is surrounded in the middle of the frame structure 214.

The middle layer glass 212 arranged in the containing cavity 2140 divides the containing cavity 2140 into the first cavity 217 and the second cavity 218. The air outlet 215 and the air inlet 216 are arranged on the frame structure 214. For example, the air inlet 216 is arranged on one side of the frame structure 214 at the bottom of the door body assembly 210, and the air outlet 215 is arranged on one side of the frame structure 214 at the top of the door body assembly 210, so that the cold air driven by the cooling fan flows from the bottom to the top of the door body assembly 210, and the heat inside the door body assembly 210 is taken away.

[0045] Referring to Figure 1 and Figure 2 The left and right sides of the frame structure 214 further have a secondary air outlet 219, and the total area of the secondary air outlet 219 is smaller than that of the air outlet 215. Most of the cold air is discharged from the air outlet 215 above, and a small part of the cold air can be discharged from the secondary air outlet 219.
