[0002] Embedded kitchen electrical products such as steam and oven integrated machines with multiple functions are increasingly favored by consumers, and with the development of home integration, the appearance integration of household appliances is also improved. The common embedded steam and oven integrated machine generally adopts an appearance design of separating the display panel and the door assembly upward and downward, which causes obvious segmentation in vision and affects the overall aesthetic appearance of the product.

[0003] In order to improve the appearance integration, some steam and oven integrated machines integrate the display screen on the handle of the door body, which makes the shape of the door handle become bulky and affects the overall visual aesthetic of the product.

[0004] In order to improve the appearance integration of the cooking device, it is considered to integrate the display screen on the door body, but in the existing technology, in the door body structure and appearance design of the steam and oven integrated machine, it is difficult to ensure that the electronic elements of the display screen embedded in the door body can achieve good heat dissipation effect and stable operation while maintaining the basic functions of the door body such as heat preservation, heat insulation and effective vapor isolation. This is because: when the steam and oven integrated machine is in the baking mode, the highest temperature of the inner container generally exceeds 200 degrees Celsius, and the door body opposite to the inner container bears the functions of heat preservation and heat insulation, so that the internal temperature of the door body is high when the baking function works, which is not conducive to the normal operation of the electronic elements in the display screen. Only the oven with baking function, the oven door body usually increases the heat dissipation holes around the oven door body to improve the air convection between the inside and outside of the door body, and increase the heat dissipation effect of the inside of the door body. But when the steam and oven integrated machine is in the steaming mode, there is a lot of hot steam in the inner container for steaming food, and the door body needs to isolate the water vapor in addition to the functions of heat preservation and heat insulation, so as to avoid the water vapor from spreading to the outside and burning the user's skin, and also to avoid the water vapor from entering the inside of the door body and affecting the reliability of the electronic elements in the door body.

[0032] Referring to Figure 1 and Figure 2 , Figure 1 and Figure 2 The structure schematic diagram of different perspectives of the cooking equipment 100 in an embodiment of the present application is shown. The cooking equipment 100 provided by the embodiment of the present application can be a steam oven, or a steam oven or an oven.

[0033] In combination with Figure 3 shown, Figure 3 The cross-sectional schematic diagram of the cooking equipment 100 in an embodiment of the present application is shown. The cooking equipment 100 includes an inner container 110, a door body 120, a display screen 130 and a cooling water tank 140. The inner container 110 is provided with a cooking cavity 111 with an open mouth 1111, and the cooking cavity 111 is used to place and cook food materials. It can be understood that when the cooking equipment 100 cooks food materials, the temperature in the cooking cavity 111 is higher than the room temperature.

[0034] The door body 120 covers the inner container 110, and as shown in Figure 2 The door body 120 is provided with a front end face 1211 facing away from the cooking cavity 111, and the front end face 1211 includes a display area 1212 for placing the display screen 130, as shown in Figure 3 The display screen 130 is connected to the door body 120 and located inside the door body 120 to avoid the display screen 130 protruding outward and affecting the appearance of the door body 120. The display screen 130 is located at the display area 1212, so that the content displayed by the display screen 130 can be displayed at the display area 1212, and when the display screen 130 is a touch screen, the user can interact with the display screen 130 by touching the display area 1212.

[0035] As shown in Figure 3 The cooling water tank 140 is attached to the side of the display screen 130 facing the cooking cavity 111, and the cooling water tank 140 has an internal water storage space for storing water to isolate the cooking cavity 111 and the display screen 130 through the cooling water tank 140, avoiding direct heat exchange between the cooking cavity 111 and the display screen 130. Since water has a high specific heat capacity, even if the temperature in the cooking cavity 111 rises, the water temperature in the cooling water tank 140 rises less, thereby avoiding the temperature of the display screen 130 being too high to affect the normal operation of the electronic components inside the display screen 130.

[0036] As shown in Figure 3 In one embodiment, the door body 120 includes an outer plate 121 and an inner plate 122 arranged at intervals, and the space between the outer plate 121 and the inner plate 122 forms a placement space 123, and the display screen 130 and the cooling water tank 140 are both located in the placement space 123 to seal the cooking cavity 111 through the inner plate 122, avoiding the heat and moisture in the cooking cavity 111 from spreading to the outside. As shown in Figure 2 and Figure 3 The front end face 1211 is the end face of the outer plate 121 facing away from the inner plate 122, and in some embodiments, the outer plate 121 is made of glass to facilitate seeing the content displayed by the display screen 130 through the outer plate 121.

[0037] As shown in Figure 4 In one embodiment, the cooling water tank 140 is provided with a water inlet 141 and a water return port 142, and the water return port 142 is located above the water inlet 141 to avoid the water in the cooling water tank 140 flowing out completely and failing to achieve the cooling effect.

[0038] In one embodiment, the water return port 142 is located at the top of the cooling water tank 140, or as shown in Figure 4In the shown embodiment, the water return port 142 is located at the top of the side wall of the cooling water tank 140, so that the water level in the cooling water tank 140 is kept not lower than the middle of the cooling water tank 140, thereby avoiding the water level in the cooling water tank 140 being too low to affect the cooling effect.

[0039] As shown in the figures, Figure 4 The cooking device 100 includes a water inlet pipe 150 connected to the water inlet port 141 and a water return pipe 160 connected to the water return port 142, so as to form a circulating water path through which water flows into the cooling water tank 140 through the water inlet pipe 150 and then flows out through the water return pipe 160, thereby realizing the continuous flow of water in the cooling water tank 140 and avoiding the water temperature in the cooling water tank 140 rising too much to affect the normal operation of the display screen 130.

[0040] As shown in the figures, Figure 5 In one embodiment, the inner plate 122 includes a central portion 1221 covering the opening 1111 to seal the cooking cavity 111 and an edge portion 1222 located at the outer periphery of the central portion 1221. The central portion 1221 covers the opening 1111 to seal the cooking cavity 111. The edge portion 1222 is provided with an opening 1223 communicating between the placement space 123 and the outside, so as to avoid the opening 1223 affecting the sealing of the cooking cavity 111 by the inner plate 122. In this embodiment, the opening 1223 is located at the bottom of one side edge of the inner plate 122 for ease of processing, and in other embodiments, the opening 1223 does not affect the covering and sealing of the opening 1111 by the inner plate 122. Figure 5 As shown in the figures,

[0041] As shown in the figures, Figure 1 and Figure 2 In one embodiment, the cooking device 100 further includes a water storage tank 170, and the water return pipe 160 and the water inlet pipe 150 are connected to the water storage tank 170 at the ends away from the cooling water tank 140, so as to form a circulating loop through which water circulates between the water storage tank 170 and the cooling water tank 140, so that the water flow circulates between the water storage tank 170, the water inlet pipe 150, the cooling water tank 140 and the water return pipe 160. In this embodiment, the water storage tank 170 is a water tank for supplying water to the cooking cavity 111 in the steaming function of the cooking device 100. In other embodiments, the water inlet pipe 150 can be directly connected to a water source such as a faucet, and the water return pipe 160 can be directly connected to the outside to directly discharge water.

[0042] As shown in the figures, Figure 1 and Figure 2 In one embodiment, the cooking device 100 further includes a water supply pump 180 connected to the water inlet pipe 150 and acting on the water flow in the water inlet pipe 150, so as to control the flow direction of the water flow in the circulating loop.

[0043] In some embodiments, the inlet pipe 150 is also connected to a solenoid valve to cut off the water flow. The solenoid valve is opened when it is necessary to circulate the water in the storage tank 170 to prevent backflow caused by siphoning when the water level in the storage tank 170 is higher than the water level in the cooling water tank 140.

[0044] like Figure 6 As shown, in one embodiment, the water storage tank 170 includes an inlet connector 173 for connecting to the return water pipe 160, combined with... Figure 7 The water storage tank 170 also includes an inlet inner pipe 174 located inside the water storage tank 170 and connected to the inlet connector 173. One end of the inlet inner pipe 174 away from the inlet connector 173 is located at the top inside the water storage tank 170 so that the return water from the cooling water tank 140 can flow into the water storage tank 170.

[0045] like Figure 6 As shown, in one embodiment, the water storage tank 170 includes an outlet connector 175 for connecting the inlet pipe 150, combined with... Figure 7 The water storage tank 170 also includes an outlet inner pipe 176 located inside the water storage tank 170 and connected to the outlet connector 175. The end of the outlet inner pipe 176 away from the outlet connector 175 is located at the bottom inside the water storage tank 170 to avoid the water level in the water storage tank 170 being too low to supply water to the cooling water tank 140.

[0046] like Figure 6 and Figure 7 As shown, in one embodiment, the water storage tank 170 includes a tank body 171 and a top cover 172 that fit together. The top cover 172 covers the tank body 171 to form a space for storing water. An inlet inner pipe 174 and an outlet inner pipe 176 are both connected to the top cover 172. In this embodiment, the inlet inner pipe 174 and the outlet inner pipe 176 are integrally formed with the top cover 172. In other embodiments, the inlet inner pipe 174 and the outlet inner pipe 176 can be fixedly and sealingly connected to the top cover 172.

[0047] The cooking device 100 provided in the above scheme can avoid the display screen 130 protruding outward to affect the integrity and appearance of the door body 120 by arranging the display screen 130 inside the door body 120, and the cooling water tank 140 attached to the display screen 130 is arranged on the side of the display screen 130 facing the cooking cavity 111 to isolate the cooking cavity 111 and the display screen 130 through the cooling water tank 140, so as to avoid direct heat exchange between the cooking cavity 111 and the display screen 130. Since the specific heat capacity of water is high, even if the temperature in the cooking cavity 111 rises, the water temperature in the cooling water tank 140 rises less, so as to avoid the temperature of the display screen 130 being too high to affect the normal operation of the electronic components inside the display screen 130. In the above scheme, the cooling water tank 140 is also located inside the door body 120, so that the cooling water tank 140 does not damage the sealing of the inner container 110 by the door body 120, and the integrity of the door body 120, the internal cooling of the display screen 130 for normal operation, and the sealing of the inner container 110 by the door body 120 are considered at the same time, solving the problem of sacrificing the integrity and appearance of the door body 120 in the prior art in order to consider the above performances.

[0048] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0049] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
