[0037] Cooking appliances with steaming functions typically have a glass window on the door to allow users to easily observe the cooking process, reducing the number of times the door needs to be opened and closed, thus avoiding affecting the cooking results and preventing steam overflow and potential safety hazards. However, during steaming, the large amount of steam inside the inner pot will adhere to the cooler glass window, causing excessive condensation. This makes it difficult for users to clearly observe the cooking process, negatively impacting the user experience.

[0038] To solve the above problems, such as Figures 1 to 6 As shown, this utility model first provides a door structure that allows users to clearly observe the cooking status of the ingredients.

[0039] like Figure 1 As shown, specifically, the door structure includes a door assembly 1, a wiper assembly 2, a controller (not shown), and a sensor assembly 3, wherein: the door assembly 1 has a viewing window 11; the wiper assembly 2 includes a wiper element 21 and a drive element 22 connected to the wiper element 21, the wiper element 21 is disposed on the inner surface of the door assembly 1, and the drive element 22 can drive the wiper element 21 to reciprocate relative to the door assembly 1 within a preset range, the preset range covering the viewing window 11; the controller is electrically connected to the drive element 22 and is used to control the opening and closing of the drive element 22; the sensor assembly 3 is disposed on the door assembly 1, the sensor assembly 3 is electrically connected to the drive element 22, and is used to detect the light transmittance of the door assembly 1.

[0040] The door structure is used in the cooking equipment, which also includes an inner pot with an opening. The door structure is closable at the opening. The inner surface of the door assembly 1 is the side of the door assembly 1 facing the inner pot. The controller can be located in the inner pot or the door assembly 1, or the main controller of the cooking equipment can be used as the door structure controller.

[0041] The sensor assembly 3 can detect the light transmittance of the door body assembly 1 in real time or periodically and transmit the detection result to the controller. When the sensor assembly 3 detects that the light transmittance of the door body assembly 1 is lower than a preset value, the controller controls the driving member 22 to drive the wiper 21 to reciprocate relative to the door body assembly 1 within a preset range, so that the wiper 21 can wipe off the water mist attached to the inner surface of the window 11, and the window 11 is in a visible state. The user can clearly observe the cooking state of the food through the window 11, and the cooperation of the controller, the sensor assembly 3 and the door body assembly 1 makes the door body structure more intelligent. At the same time, the controller can also adjust the movement speed of the driving member 22 to drive the wiper 21, so as to adjust the wiping efficiency.

[0042] As shown in Figure 3 and Figure 5 , the wiper 21 comprises a sliding part 212 and a silica gel part 213 arranged on one side of the sliding part 212 facing the inner surface of the door body assembly 1. The flexibility of the silica gel part 213 makes the wiper 21 better fit the inner surface of the door body assembly 1, and it is not easy to scratch the door body assembly 1, thereby improving the wiping effect, and the silica gel part 213 has wear resistance and aging resistance, which can prolong the service life of the wiper 21.

[0043] As shown in Figures 2 to 3 , the wiper assembly 2 further comprises a guide rail 23 extending along a first preset direction and located outside the window 11. The sliding part 212 of the wiper 21 is slidably arranged on the guide rail 23 and extends along a second preset direction perpendicular to the first preset direction. The guide rail 23 located outside the window 11 can avoid affecting the user's line of sight, and also ensure that the appearance of the door body structure is regular, and the wiper 21 is preferably located outside the window 11 when it is not working. The guide rail 23 can limit the movement path and range of the wiper 21, so that the wiper 21 can reciprocate relative to the door body assembly 1 along the first preset direction, improve the stability of the wiper 21 when moving, and avoid the wiper 21 from being skewed to affect the wiping effect.

[0044] As shown in Figure 3 and Figure 5 , in the illustrated embodiment, the driving member 22 is arranged as a motor push rod, which is arranged on the inner surface of the door body assembly 1 and located outside the window 11. The main body of the motor push rod is located at one end of the guide rail 23, and the output end of the motor push rod is connected with the wiper 21. Of course, in other embodiments, the driving member 22 can also be arranged as a motor sliding rail or other driving elements capable of driving the wiper 21 to slide along the first preset direction, which is not limited in the embodiments of the present application.

[0045] As shown in Figures 1 to 2As shown, in the illustrated embodiment, the first preset direction is the width direction of the door body assembly 1, i.e. the X-axis direction, and the second preset direction is the height direction of the door body assembly 1, i.e. the Y-axis direction. In this way, the overall structure of the wiper assembly 2 is regular, facilitating processing and assembly. Of course, in other embodiments, the first preset direction can be the height direction of the door body assembly 1, and the first preset direction can also be at an angle with the X-axis direction or the Y-axis direction; or the wiper 21 can also reciprocate and rotate wiping along a preset axis perpendicular to the door body assembly 1, as long as the preset range of the wiper 21 movement can cover the window 11, which is not limited in the embodiments of the present application.

[0046] As shown in Figure 1 and Figure 4 , the number of wipers 21 is two, and the two wipers 21 are oppositely arranged along the first preset direction and can slide towards each other from the two ends of the guide rail 23. The number of driving members 22 is also two, and they are arranged one-to-one corresponding to the wipers 21. Simultaneous wiping of the two wipers 21 can improve the wiping efficiency. When the first preset direction is the width direction of the door body assembly 1, the guide rail 23 can be arranged at the top or bottom of the door body assembly 1, and the two wipers 21 are located at the two ends of the guide rail 23 when not working, and are located outside the window 11, avoiding affecting the user's view, and also ensuring the regular appearance of the door body structure. When the sensor assembly 3 detects that the light transmittance of the door body assembly 1 is lower than the preset value, the two driving members 22 are controlled to simultaneously drive the two wipers 21 to slide towards the center of the door body assembly 1, and then drive the two wipers 21 to slide to the two sides of the door body assembly 1 in directions away from each other.

[0047] As shown in Figure 3 and Figure 5 , when the cooking equipment has a baking function, the inner surface temperature of the door body assembly 1 is also high, which can reach 120℃, due to the high temperature in the inner container of the cooking equipment in the baking mode. Therefore, in order to prevent the wiper 21 from being in contact with the inner surface of the door body assembly 1 with high temperature for a long time and affecting the service life of the wiper 21, the wiper 21 is provided with a water spraying hole 211, and the door body structure further comprises a water supply assembly 4, which is arranged on the door body assembly 1 and located outside the window 11. The water supply assembly 4 comprises a water tank 41 and a water pump 42, and the inlet and outlet of the water pump 42 can respectively communicate with the water tank 41 and the water spraying hole 211. The water supply assembly 4 located outside the window 11 can avoid affecting the user's view, and also ensure the regular appearance of the door body structure. When the temperature detection element of the cooking equipment detects that the temperature in the inner container is higher than the preset temperature, the water pump 42 can be controlled to work, the water in the water tank 41 is pumped into the wiper 21 by the water pump 42, and is sprayed out through the water spraying hole 211, so as to reduce the temperature of the area near the inner surface of the door body assembly 1 in contact with the wiper 21, and also reduce the temperature of the wiper 21, thereby prolonging the service life of the wiper 21.

[0048] Specifically, when the first preset direction is the width direction of the door body assembly 1, the water tank 41 can be arranged at the top or the bottom of the door body assembly 1 to ensure the balance of the door body assembly 1 as a whole. In addition, the water outlet of the water pump 42 can be connected to the water spray hole 211 only when the wiper 21 is located at the two sides of the door body assembly 1, and the water spray hole 211 can be disconnected from the water outlet of the water pump 42 when the wiper 21 slides towards the other side. Alternatively, the water spray hole 211 and the water outlet of the water pump 42 can be connected through a water pipe or other structures, that is, the water spray hole 211 and the water outlet of the water pump 42 are always in a connected state.

[0049] As shown in Figure 3 and Figure 5 , the number of water spray holes 211 is multiple, and the multiple water spray holes 211 are arranged at intervals along the second preset direction. The multiple water spray holes 211 enable water to be sprayed to each position of the wiper 21, thereby improving the cooling effect of the wiper 21 and further prolonging the service life of the wiper 21. Specifically, the water tank 41 arranged in the sliding part 212 of the wiper 21 is provided with a water channel (not shown in the figure) extending along the second preset direction, each water spray hole 211 is connected to the water channel, and one end of the water channel can be connected to the water outlet of the water pump 42, so that each water spray hole 211 can be connected to the water outlet of the water pump 42.

[0050] As shown in Figure 4 and Figure 6As shown, the sensor assembly 3 comprises a first sensor 31 and a second sensor 32, one of which is used to emit light, and the other is used to receive light; the door body assembly 1 comprises an outer door body 12 and an inner door body 13 arranged in layers, the first sensor 31 is arranged on one side of the outer door body 12 facing the inner door body 13, and the second sensor 32 is arranged on the inner door body 13 and corresponds to the first sensor 31. For the sake of description, the following is described by taking the first sensor 31 for emitting light and the second sensor 32 for receiving light as an example. Among them, the side of the inner door body 13 away from the outer door body 12 is the inner surface of the door body assembly 1, and the second sensor 32 can be at least partially embedded in the inner door body 13, but the receiving surface of the second sensor 32 needs to be flush with the side of the inner door body 13 away from the outer door body 12, in order to ensure the detection effect of the sensor assembly 3, and also to avoid affecting the normal work of the wiper 21. The corresponding arrangement of the first sensor 31 and the second sensor 32 means that the projection of the first sensor 31 on the outer door body 12 coincides with the second sensor 32, so that the second sensor 32 can accurately receive the light emitted by the first sensor 31. When the light emitted by the first sensor 31 towards the second sensor 32 is certain, the more water mist on the inner surface of the inner door body 13, the weaker the light received by the second sensor 32, and the weaker the light transmittance of the door body assembly 1, when the sensor assembly 3 detects that the light transmittance of the door body assembly 1 is lower than the preset value, the controller controls the driving member 22 to start working. In this way, the sensor assembly 3 has a simple structure and low cost, facilitating processing and assembly.

[0051] As shown in Figure 2 , the door body assembly 1 can also comprise a middle door body 14 arranged between the outer door body 12 and the inner door body 13, to prevent the temperature of the outer door body 12 from being too high to cause the user to be scalded at will. The first sensor 31 is arranged between the outer door body 12 and the middle door body 14, and is attached to one side of the outer door body 12 facing the middle door body 14.

[0052] As shown in Figure 4 and Figure 6 , the door body structure is rectangular, and the number of sensor assemblies 3 is four, and the four sensor assemblies 3 are arranged at the four corners of the door body structure. In this way, the program of the controller can be set to control the driving member 22 to start working when at least two or three sensor assemblies 3 detect that the light transmittance of the door body assembly 1 is lower than the preset value. Avoiding that the local water mist of the door body assembly 1 is serious or the sensor assembly 3 is damaged, causing the wiper assembly 2 to repeatedly wipe, thereby prolonging the service life of the wiper assembly 2.

[0053] The embodiment of the utility model provides a kind of cooking equipment, including the door body structure of above. Specifically, cooking equipment also includes inner bag (figure is not shown), inner bag has opening, and door body structure is open and close to be located in opening.Among them, cooking equipment can be steamer, steam oven and other equipment with steaming function, the utility model embodiment does not make specific limit here.
