Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a cabinet door structure and an oven. BACKGROUND

[0002] At present, cameras are gradually applied to the cabinet door structure of an oven to meet the needs of intelligent cooking. The harsh temperature environment in the oven body is a great test for the service life of the camera. The heat in the oven body will be conducted to the camera installation area of the cabinet door through the cabinet door glass. Therefore, the flow field of the camera installation area needs to be designed to make the temperature around the camera below the allowable temperature of the camera.

[0003] In the related art, when the oven is working, the camera is fixedly installed at the upper middle part of the cabinet door of the oven, and a heat dissipation fan is arranged on the cabinet door. When the camera is shooting the internal environment of the oven body, the heat dissipation fan drives the airflow in the cabinet door to flow, thereby dissipating heat for the camera. However, the above structure has the following disadvantages. First, the shooting height of the camera is single and limited. Users need to consciously place the food in the coverage area of the camera, and it is difficult to achieve accurate shooting of the food at each layer in the oven. Second, the airflow is relatively dispersed when the airflow is used to dissipate heat for the camera only by the heat dissipation fan, and it is difficult to concentrate on dissipating heat for the camera. Therefore, the heat dissipation effect is poor. The above two disadvantages reduce the user experience and are difficult to meet the market demand. SUMMARY

[0045] At present, cameras are gradually applied to oven cabinet door structures to meet the needs of intelligent cooking. The harsh temperature environment in the oven body is a great test for the service life of the camera. The heat in the oven body will be conducted to the camera installation area of the cabinet door through the cabinet door glass, and the flow field of the camera installation area needs to be designed to keep the temperature around the camera below the allowable temperature of the camera.

[0046] In the related art, when the oven is working, the camera is fixedly installed in the upper middle of the oven cabinet door, and a heat dissipation fan is arranged on the cabinet door. When the camera is shooting the internal environment of the oven body, the heat dissipation fan drives the airflow in the cabinet door to flow, and the camera is cooled. However, the above structure has the following disadvantages: first, the shooting height of the camera is single and limited, and the user needs to consciously place the food in the coverage area of the camera, which is difficult to realize accurate shooting of each layer of food in the oven; second, the airflow is relatively dispersed by only driving the airflow to cool the camera through the heat dissipation fan, and it is difficult to concentrate on cooling the camera, and the cooling effect is poor. The above two disadvantages reduce the user experience and are difficult to meet market demand.

[0047] Based on this, one or more embodiments of the present application provide a cabinet door structure. Through the cooperation of the cabinet door, the image acquisition assembly, and the flow guide piece, the image acquisition assembly can move in the height direction for shooting work, and the cooking state of each layer of food in the cooking cavity can be obtained in real time. At the same time, whether the image acquisition assembly is in a moving shooting work state or a stationary shooting work state, the flow guide piece can relatively centrally cool and reduce the temperature of the image acquisition assembly and the inner door body through the guiding effect of the airflow, effectively reducing the risk of damage to the image acquisition assembly and the inner door body caused by high temperature, and indirectly reducing the risk of damage to the outer door body caused by high temperature. In this way, the overall structural reliability and service life of the image acquisition assembly and the cabinet door are improved, the user's use experience is improved, and the market demand is effectively met.

[0048] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the present application provides a cabinet door structure, which includes a cabinet door 100, an image acquisition assembly 200, and a flow guide piece 300.

[0049] The cabinet door 100 includes an inner door body 110 and an outer door body 120. The inner door body 110 and the outer door body 120 are oppositely arranged and form a heat dissipation ventilation channel 130 extending along the height direction Z of the cabinet door 100 therebetween. A light transmission area R is formed on the inner door body 110, and the extension direction of the light transmission area R is consistent with the extension direction of the heat dissipation ventilation channel 130.

[0050] The image acquisition assembly 200 and the flow guide piece 300 are both installed in the heat dissipation ventilation channel 130. The image acquisition assembly 200 is arranged on the flow guide piece 300, and the shooting end of the image acquisition assembly 200 faces the light transmission area R. The flow guide piece 300 is slidingly connected to the cabinet door 100 to drive the image acquisition assembly 200 to move along the heat dissipation ventilation channel 130. The flow guide piece 300 is also used to guide the airflow entering the heat dissipation ventilation channel 130 to the image acquisition assembly 200 and the inner door body 110.

[0051] It should be noted that the cabinet door structure of the present application can be applied to, but is not limited to, ovens, air fryers, dishwashers, and other household electrical appliances.

[0052] Exemplarily, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7When the cabinet door structure is arranged in an oven, the oven comprises a cabinet 500 and the cabinet door structure, the cabinet 500 has a cooking cavity 510, one side of the cabinet 500 has an opening 520 which is in communication with the cooking cavity 510, and the cabinet door 100 is arranged at the opening 520 and used to open or close the opening 520, and the shooting end of the image acquisition assembly 200 faces the cooking cavity 510.

[0053] The cabinet door 100 can be rotatably arranged at the opening 520 of the cabinet 500 of the oven, so as to rotatably open or close the opening 520 of the cabinet 500. The height direction Z of the cabinet door 100 is consistent with the height direction Z of the cabinet 500 of the oven, and the light transmission area R of the inner door body 110 covers the opening of the cabinet 500, so that the light emitted by the shooting end of the image acquisition assembly 200 can pass through the light transmission area R and enter the cabinet 500, and the cooking state of the food in the cabinet 500 can be accurately captured and acquired.

[0054] The function of the cabinet door structure will be further described below by taking the oven as an example.

[0055] In the present application, the cabinet door 100 can further comprise a door frame, and the inner door body 110 and the outer door body 120 are both arranged on the door frame, and the inner door body 110 and the outer door body 120 can be parallel and spaced apart along the thickness direction of the cabinet door 100, so that a heat dissipation and ventilation channel 130 extending in the height direction Z of the cabinet door 100 is formed between the inner door body 110 and the outer door body 120.

[0056] The cabinet 500 is provided with a fan (not shown in the figure) near the inlet or outlet of the heat dissipation and ventilation channel 130, the fan introduces the airflow with lower external temperature into the heat dissipation and ventilation channel 130, and the airflow flows from bottom to top along the heat dissipation and ventilation channel 130, so as to realize heat dissipation and cooling of the inner door body 110, the outer door body 120 and the image acquisition assembly 200 in the heat dissipation and ventilation channel 130, and reduce the risk of damage of the inner door body 110, the outer door body 120 and the image acquisition assembly 200 caused by heat. Of course, the fan can also be directly arranged at the inlet or outlet of the heat dissipation and ventilation channel 130.

[0057] The inner door body 110 can be a glass door, and the extension surface of the inner door body 110 forms the light transmission area R. Since the inner door body 110 directly faces the cooking cavity 510 of the cabinet 500, the heat insulation requirement of the inner door body 110 is higher, and the inner door body 110 can be arranged as a hollow glass door, and the air layer or vacuum layer in the hollow glass door is used for heat insulation, so that the inner door body 110 has good heat resistance and heat insulation performance, and the heat conduction from the cabinet 500 of the oven to the inner door body 110 and the outer door body 120 is reduced.

[0058] The outer door body 120 can also be a glass door. Since the outer door body 120 directly faces the user, the outer door body 120 also needs to be heat-insulated. A heat-insulating layer can be coated on the surface of the outer door body 120 to reduce the temperature of the outer door body 120 during use, thereby reducing the risk of the user being scalded by the outer door body 120 and improving the use safety of the cabinet door structure.

[0059] It should be noted that, in the present application, the extension direction of the light-transmitting area R is consistent with the extension direction of the heat dissipation ventilation channel 130 can be understood as that the shape and size of the inner door body 110 or the light-transmitting area R are equal to those of the heat dissipation ventilation channel 130, or the orthographic projection of the heat dissipation ventilation channel 130 on the surface of the inner door body 110 or the light-transmitting area R of the inner door body 110 is coincident with the surface of the inner door body 110 or the light-transmitting area R of the inner door body 110. For example, the inner door body 110 and the outer door body 120 are both rectangular bodies, and the heat dissipation ventilation channel 130 corresponds to a rectangular body.

[0060] For the image acquisition assembly 200, it is a general optical camera assembly, such as a CCD camera. For the flow guide 300, it can be a special-shaped flow guide plate, such as an inverted V-shaped flow guide plate, an arched flow guide plate, etc. A guide rail can be arranged on the surface of the inner door body 110 facing the heat dissipation ventilation channel 130 or the surface of the outer door body 120 facing the heat dissipation ventilation channel 130. The flow guide 300 is slidingly connected to the guide rail through a sliding block or a pulley, and the image acquisition assembly 200 is detachably arranged on the flow guide 300.

[0061] In this way, the flow guide 300 drives the image acquisition assembly 200 thereon to slide up and down on the heat dissipation ventilation channel 130, so that the image acquisition assembly 200 can shoot the images of each layer of food materials in the cooking cavity 510 of the box body 500 through the light-transmitting area R of the inner door body 110, and the user can obtain the cooking state of each layer of food materials in real time through the food material images, such as the color of the food materials and the maturity of the food materials.

[0062] During the use of the oven, the cabinet door 100 can isolate part of the heat in the cooking cavity 510, but during the cooking process, the cabinet door 100 also has a problem of temperature rise under the action of heat conduction and heat radiation. Long-time cooking can also cause damage to the image acquisition assembly 200. In addition, the inner door body 110 directly faces the cooking cavity 510, and its temperature is obviously higher than that of the outer door body 120, so the risk of being damaged by heat is larger.

[0063] Based on this, by slidingly connecting the guide member 300 to the cabinet door 100 and arranging the image acquisition assembly 200 on the guide member 300, the guide member 300 drives the image acquisition assembly 200 to slide up and down along the heat dissipation air duct 130, so that the image acquisition assembly 200 can capture the cooking state of each layer of food in the cooking cavity 510. At the same time, during the image acquisition assembly 200 capturing process, by using the flow guiding effect of the guide member 300, the guide member 300 can guide the airflow entering the heat dissipation air duct 130 to the image acquisition assembly 200 and the inner door body 110, so that the airflow can more concentratedly dissipate heat to the image acquisition assembly 200 and the inner door body 110, relatively concentratedly reduce the temperature of the image acquisition assembly 200 and the inner door body 110, effectively reduce the risk of high-temperature damage to the image acquisition assembly 200 and the inner door body 110, and indirectly reduce the heat conduction from the inner door body 110 to the outer door body 120, thereby also reducing the risk of high-temperature damage to the outer door body 120.

[0064] In addition, when the user does not need to use the image acquisition assembly 200 for shooting, in the image acquisition assembly 200 is in the shutdown state, the guide member 300 can also drive the image acquisition assembly 200 to slide up and down along the heat dissipation air duct 130, and by using the flow guiding effect of the guide member 300, the airflow in the heat dissipation air duct 130 can be guided by the guide member 300 to uniformly dissipate heat to each part of the inner door body 110, thereby relatively uniformly reducing the heat of the inner door body 110 and reducing the risk of local overheating damage to the inner door body 110.

[0065] It can be understood that the cabinet door structure described above, by cooperating the cabinet door 100, the image acquisition assembly 200 and the guide member 300, can make the image acquisition assembly 200 move in the height direction for shooting, and can real-time acquire the cooking state of each layer of food in the cooking cavity 510. At the same time, whether the image acquisition assembly 200 is in the moving shooting state or the static shooting state, by using the flow guiding effect of the guide member 300, the image acquisition assembly 200 and the inner door body 110 can be relatively concentratedly dissipated heat, the temperature of the image acquisition assembly 200 and the inner door body 110 can be relatively concentratedly reduced, the risk of high-temperature damage to the image acquisition assembly 200 and the inner door body 110 can be effectively reduced, and the risk of high-temperature damage to the outer door body 120 can be indirectly reduced, thereby improving the overall structural reliability and service life of the image acquisition assembly 200 and the cabinet door 100, improving the user's experience, and effectively meeting the market demand.

[0066] Referring to Figure 9 and Figure 10 , wherein, Figure 9 is the velocity field streamline diagram and the temperature cloud diagram of the inside of the cabinet door of the embodiment of the present application, and Figure 9In the middle, from left to right, the outer door body 120, the flow guide piece 300 provided with the image acquisition assembly 200, and the inner door body 110 are sequentially distributed, the gray depth corresponds to the temperature, the darker the gray, the higher the temperature, the lighter the gray, the lower the temperature, and the curve with an arrow corresponds to the airflow. Figure 10 For the velocity field simulation cloud chart of the inside of the cabinet door of the embodiment of the present application, in Figure 10 In the middle, the cloud chart gray depth corresponds to the airflow velocity, the darker the gray, the more airflow distribution, the larger the airflow velocity, the lighter the gray, the less airflow distribution, and the smaller the airflow velocity.

[0067] Based on Figure 9 and Figure 10 , it is not difficult to see that the cabinet door structure of the embodiment of the present application, through the cooperation of the cabinet door 100, the image acquisition assembly 200, and the flow guide piece 300, the airflow relatively concentrates to the image acquisition assembly 200 and the inner door body 110, so that the image acquisition assembly 200 and the inner door body 110 are cooled to a higher degree than the outer door body 120, and the temperature of the image acquisition assembly 200 is lower than that of the inner door body 110 and the outer door body 120, which can directly reflect that the above-mentioned structure can relatively concentrate heat dissipation of the image acquisition assembly 200 and the inner door body 110, relatively concentrate the temperature reduction of the image acquisition assembly 200 and the inner door body 110, and effectively reduce the risk of damage of the image acquisition assembly 200 and the inner door body 110 by high temperature.

[0068] In some embodiments of the present application, referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the flow guide piece 300 extends obliquely from the bottom end to the top end of the flow guide piece 300 towards the inner door body 110, and the image acquisition assembly 200 is arranged at the top end of the flow guide piece 300.

[0069] Specifically, the flow guide piece 300 can be configured as an inverted V-shaped flow guide plate, and the image acquisition assembly 200 is arranged at the top end of the inverted V-shaped flow guide plate. Alternatively, the flow guide piece 300 can be configured as an arched flow guide plate, and the image acquisition assembly 200 is also arranged at the top end of the arched flow guide plate.

[0070] The above-mentioned structure, referring to 5 and Figure 6 , the bottom end and the top end of the flow guide piece 300 are close to the outer door body 120 and the inner door body 110 respectively, the airflow can flow from bottom to top along the inclined profile of the flow guide piece 300 to the direction close to the inner door body 110 and the image acquisition assembly 200, so that more airflow more concentrates heat dissipation of the inner door body 110 and the image acquisition assembly 200, improves the cooling efficiency of the inner door body 110 and the image acquisition assembly 200, and further reduces the risk of damage of the image acquisition assembly 200 and the inner door body 110 by high temperature.

[0071] In some embodiments of the present application, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the flow guide 300 comprises a bearing segment 310 and two flow guide segments 320, the two flow guide segments 320 are respectively connected to opposite ends of the bearing segment 310; the flow guide segment 320 extends obliquely from its bottom end to its top end towards the direction of the inner door body 110 to be connected to the bearing segment 310, the image acquisition assembly 200 is arranged on the bearing segment 310, and the bearing segment 310 or at least one flow guide segment 320 is slidingly connected to the cabinet door 100.

[0072] Specifically, the bearing segment 310 and the two flow guide segments 320 are an integrally formed structure. With the cabinet door 100 as a reference system, the top end to the bottom end of the flow guide segment 320 extends from the middle of the heat dissipation ventilation channel 130 to the end close to the width direction Y of the heat dissipation ventilation channel 130.

[0073] The cabinet door structure further comprises a guide rail 400, the guide rail 400 is arranged on one side surface of the inner door body 110 close to the outer door body 120, and the guide rail 400 extends along the height direction Z of the inner door body 110, and the flow guide 300 is slidingly connected to the guide rail 400.

[0074] Specifically, the one side surface of the inner door body 110 close to the outer door body 120 is provided with the guide rail 400 at opposite ends along the width direction Y, the guide rail 400 extends along the height direction Z of the inner door body 110, and the two bearing segments 310 are respectively slidingly connected to the corresponding guide rail 400 through pulleys (not shown in the figure). The bearing segment 310 is suspended in the heat dissipation ventilation channel 130 by the support of the two flow guide segments 320.

[0075] The cabinet door structure further comprises a driving member (not shown in the figure), a driving end of the driving member is connected to the flow guide 300, so as to drive the flow guide 300 to slide up and down along the guide rail 400, thereby driving the image acquisition assembly 200 to slide up and down to take pictures. The driving member can be a pneumatic cylinder, a linear motor, etc.

[0076] Alternatively, referring to Figure 2 、 Figure 3 and Figure 4 , in other embodiments, the guide rail 400 is a rack, the two bearing segments 310 are respectively provided with a gear 410, the gear 410 engages the corresponding guide rail 400, the driving member is fixed on one of the bearing segments 310 or the driving member is fixed on the flow guide segment 320, and the driving member is a motor, the motor is drivingly connected to one of the gears 410. In this way, the motor rotates, and the flow guide 300 slides up and down along the guide rail 400 under the meshing transmission of the guide rail 400 and the gear 410.

[0077] The structure described above, whether the image acquisition assembly 200 carried by the flow guide 300 slides up and down along the heat dissipation air duct 130 or the flow guide 300 and the image acquisition assembly 200 thereon are at a certain position in the heat dissipation air duct 130, the airflow in the heat dissipation air duct 130 can be relatively concentrated from bottom to top along the inclined profile of the flow guide section 320 to the bearing section 310, thereby relatively concentratedly dissipating heat for the image acquisition assembly 200, and in the process of airflow flowing from bottom to top along the flow guide section 320, the airflow gradually approaches the inner door body 110, thereby dissipating heat for the inner door body 110.

[0078] Here, the bearing section 310 is suspended in the heat dissipation air duct 130 by the support of the two flow guide sections 320 connected at both ends thereof, and the airflow distributed in the width direction Y of the heat dissipation air duct 130 can be gathered to the bearing section 310 from bottom to top along the inclined profile of the corresponding flow guide section 320, thereby more concentratedly dissipating heat for the image acquisition assembly 200 and rapidly reducing the temperature of the image acquisition assembly 200.

[0079] Further, referring again to Figure 2 、 Figure 3 and Figure 4 , the two flow guide sections 320 are symmetrically distributed relative to the bearing section 310.

[0080] Specifically, the top end of the flow guide section 320 is connected to one end of the bearing section 310 along the width direction Y thereof, and the connection mode can be arc transition connection to reduce the wind resistance of the surface of the flow guide 300, and the flow guide section 320 extends from the middle of the width direction Y of the heat dissipation air duct 130 to the end of the width direction Y of the heat dissipation air duct 130 from the top end to the bottom end thereof.

[0081] That is, the flow guide 300 as a whole is an axisymmetric structure, and the axis of symmetry is inclined at a certain angle relative to the height direction of the cabinet door 100, and at the same time, the flow guide 300 as a whole is arranged across the width direction Y of the heat dissipation air duct 130.

[0082] In this way, the overall width of the flow guide 300 can cover the overall width of the heat dissipation air duct 130, further enabling the airflow distributed in the width direction Y of the heat dissipation air duct 130 to be gathered to the bearing section 310 from bottom to top along the inclined profile of the flow guide sections 320 at both ends of the bearing section 310, thereby more concentratedly dissipating heat for the image acquisition assembly 200, rapidly reducing the temperature of the image acquisition assembly 200, and further reducing the risk of damage to the image acquisition assembly 200 by high temperature.

[0083] In addition, the airflow distributed in the width direction Y of the heat dissipation air duct 130 can gradually flow to each part of the height direction Z of the inner door body 110 along the inclined profile of the flow guide section 320 at both ends of the bearing section 310, so that the inner door body 110 can be evenly cooled, the temperature of each part of the inner door body 110 can be reduced more evenly and quickly, the probability of local overheating damage of the inner door body 110 can be reduced, and the risk of damage of the inner door body 110 by high temperature can be further reduced.

[0084] Further, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the bearing section 310 extends obliquely from the bottom end to the top end of the bearing section 310 towards the inner door body 110.

[0085] Specifically, the image acquisition assembly 200 includes a camera 210 and a circuit board 220, the position of the camera 210 on the bearing section 310 is higher than the position of the circuit board 220 on the bearing section 310, and the position of the camera 210 on the flow guide 300 is closer to the inner door body 110 than the position of the circuit board 220 on the flow guide 300, so as to shorten the distance between the camera 210 and the cooking cavity 510, but the camera 210 is heated more than the circuit board 220.

[0086] Based on this, by setting the bearing section 310 to extend obliquely from the bottom end to the top end of the bearing section 310 towards the inner door body 110, the airflow gathered from the bottom to the top of the bearing section 310 will continue to concentrate on the camera 210 with higher temperature along the inclined profile of the bearing section 310, so as to more concentratedly cool the camera 210 and reduce the risk of damage of the camera 210 by high temperature. Similarly, in the process of moving of the airflow along the inclined profile of the bearing section 310 towards the camera 210, the airflow will first cool the circuit board 220 to ensure the structural reliability of the circuit board 220.

[0087] It can be understood that the above structure can make the camera 210 of the image acquisition assembly 200 closer to the cooking cavity 510 to more accurately acquire the image of the food material, while the airflow can be gathered and concentrated at the camera 210, so as to efficiently cool the camera 210 and avoid damage of the camera 210 by high temperature.

[0088] Further, referring to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7The bottom end of the flow guide section 320 is formed with a first avoiding section 321, which is spaced apart from the outer door body 120 and is arc-shaped bent towards the inner door body 110 from the top end to the bottom end.

[0089] The top end of the flow guide section 320 is formed with a second avoiding section 322, which is spaced apart from the inner door body 110 and is bent towards the outer door body 120 from the bottom end to the top end.

[0090] Specifically, the first avoiding section 321 has the same extension length as the bottom end of the flow guide section 320, and the first avoiding section 321 is arc-shaped transitionally connected with the bottom end of the flow guide section 320.

[0091] Similarly, the second avoiding section 322 has the same extension length as the top end of the flow guide section 320, and the second avoiding section 322 is arc-shaped transitionally connected with the top end of the flow guide section 320.

[0092] The camera 210 and the circuit board 220 of the image acquisition assembly 200 are located on the upper surface of the bearing section 310, the camera 210 is closer to the inner door body 110 than the circuit board 220 on the upper surface of the flow guide 300, and the shooting end of the camera 210 is penetrated or embedded into the lower surface of the bearing section 310, so as to directly shoot the food material image in the cooking cavity 510 through the light transmission area R.

[0093] Therefore, by setting the above structure, the gap space for the airflow to pass through is formed between the first avoiding section 321 and the outer door body 120, and the gap space for the airflow to pass through is formed between the second avoiding section 322 and the inner door body 110. Under the driving of the fan, the airflow flows from bottom to top to the flow guide 300 and is divided into two parts under the shunting effect of the first avoiding section 321. One part of the airflow flows to the upper surface of the flow guide section 320 under the guidance of the arc-shaped first avoiding section 321 and flows to the circuit board 220 and the camera 210 on the bearing section 310 along the upper surface of the flow guide section 320. The other part of the airflow directly flows to the shooting end of the camera 210 on the bearing section 310 along the lower surface of the flow guide section 320.

[0094] In this way, the airflow is divided into two parts while flowing along the inclined profile of the flow guide 300 as a whole from bottom to top, one part of the airflow successively cools the circuit board 220 and the camera 210, and the other part of the airflow successively cools the shooting end of the camera 210 and the camera 210, so that each part of the image acquisition assembly 200 is evenly cooled, and the cooling efficiency of the image acquisition assembly 200 is further improved.

[0095] In some embodiments of the present application, referring to Figure 2 ,Figure 3 、 Figure 6 、 Figure 7 and Figure 8 , the cabinet door 100 is formed with an air inlet 150 and an air outlet 160, the air inlet 150 and the air outlet 160 are communicated with opposite ends of the heat dissipation air duct 130 respectively; and a wind guide grille 140 is arranged at the air inlet 150 and divides the air inlet 150 into a plurality of air inlet channels 151.

[0096] Specifically, the heat dissipation air duct 130 is a rectangular body channel, the upper end of the heat dissipation air duct 130 is the air outlet 160, and the lower end is the air inlet 150. The wind guide grille 140 covers the air inlet 150, and the air inlet 150 is divided into a plurality of air inlet channels 151 by the grille openings of the wind guide grille 140.

[0097] The above structure can adaptively adjust the size of each air inlet channel 151 based on the temperature distribution of each part of the image acquisition assembly 200 in the heat dissipation air duct 130, so that the air inlet channel 151 with a larger area is opposite to the part (such as the camera 210) with a relatively high temperature on the image acquisition assembly 200, and the air inlet channel 151 with a smaller area is opposite to the part (such as the circuit board 220) with a relatively low temperature on the image acquisition assembly 200. The image acquisition assembly 200 is cooled in a targeted and directional manner, the difficulty of cooling the image acquisition assembly 200 due to the large temperature difference of each part of the image acquisition assembly 200 is reduced, the image acquisition assembly 200 is effectively cooled quickly, and the service life of the image acquisition assembly 200 as a whole is improved.

[0098] Further, referring to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the image acquisition assembly 200 includes a camera 210 and a circuit board 220, the camera 210 is in communication connection with the circuit board 220, and the position of the camera 210 on the flow guide 300 is closer to the inner door body 110 than the position of the circuit board 220 on the flow guide 300.

[0099] The air inlet channel 151 opposite to the camera 210 in all air inlet channels 151 is defined as a first opposite area S1, the air inlet channel 151 opposite to the circuit board 220 in all air inlet channels 151 is defined as a second opposite area S2, and the orthogonal projection area of the first opposite area S1 on the air inlet 150 is greater than the orthogonal projection area of the second opposite area S2 on the air inlet 150.

[0100] Specifically, the air guide grille 140 divides the air inlet 150 into a plurality of air inlet channels 151 distributed along the length direction X of the heat dissipation air duct 130, the air inlet channels 151 close to the inner door body 110 form the first directly facing area S1, the air inlet channels 151 close to the outer door body 120 form the second directly facing area S2, the orthographic projection of the camera 210 on the air inlet 150 is in the first directly facing area S1, and the orthographic projection of the circuit board 220 on the air inlet 150 is in the second directly facing area S2.

[0101] In this way, the air flow of the first directly facing area S1 is greater than that of the second directly facing area S2, and the air flow flowing to the camera 210 is greater than that flowing to the circuit board 220, thereby ensuring heat dissipation of the circuit board 220 while relatively concentrating heat dissipation of the camera 210 and the inner door body 110, and further improving the heat dissipation efficiency of the image acquisition assembly 200 and the inner door body 110.

[0102] It should be noted that, referring to Figure 5 , Figure 6 , Figure 7 and Figure 8 , in order to reduce the installation space occupied by the image acquisition assembly 200, the orthographic projection of the camera 210 on the air inlet 150 and the orthographic projection of the circuit board 220 on the air inlet 150 partially overlap, that is, the first directly facing area S1 and the second directly facing area S2 can partially overlap.

[0103] Similarly, referring to Figure 9 and Figure 10 , based on Figure 9 and Figure 10 , it is not difficult to see that the cabinet door structure of any of the above embodiments, in use, the air flow will relatively concentrate to the image acquisition assembly 200 and the inner door body 110, so that the image acquisition assembly 200 and the inner door body 110 are cooled to a higher degree than the outer door body 120, and the temperature of the image acquisition assembly 200 is lower than that of the inner door body 110 and the outer door body 120, which can directly reflect that the above structure can relatively concentrate heat dissipation of the image acquisition assembly 200 and the inner door body 110, relatively concentrate the temperature reduction of the image acquisition assembly 200 and the inner door body 110, and effectively reduce the risk of damage to the image acquisition assembly 200 and the inner door body 110 by high temperature.

[0104] In addition, referring to Figure 1 , Figure 2 and Figure 5 , the present application also provides an oven, which comprises an oven body 500 and the cabinet door structure of any of the above embodiments.

[0105] The box body 500 has a cooking cavity 510, and one side of the box body 500 has an opening 520 in communication with the cooking cavity 510. The cabinet door 100 is arranged at the opening 520 and is used to open or close the opening 520. The shooting end of the image acquisition assembly 200 is inclined at a preset angle towards the bottom end of the cooking cavity 510.

[0106] Specifically, the cabinet door 100 can be hinged to the box body 500 by a hinge to rotate to open or close the opening 520. A plurality of layers of carriers (not shown in the figure) are arranged in the cooking cavity 510 along the height direction Z, and the carriers are used to carry food materials. The camera 210 of the image acquisition assembly 200 is inclined at a preset angle towards the bottom end of the cooking cavity 510, so that the shooting range of the camera 210 can cover each layer of carriers and can move the shooting operation in the height direction Z under the driving of the flow guide 300 to obtain the cooking state of each layer of food materials in the cooking cavity 510 in real time.

[0107] It can be understood that the oven of the embodiment of the present application has the same technical effects as the cabinet door structure, that is, the image acquisition assembly 200 can move the shooting operation in the height direction to obtain the cooking state of each layer of food materials in the cooking cavity 510 in real time. At the same time, whether the image acquisition assembly 200 is in a moving shooting operation state or a stationary shooting operation state, the image acquisition assembly 200 and the inner door body 110 can be relatively concentratedly cooled and relatively concentratedly reduced in temperature by the guiding effect of the flow guide 300 on the airflow, effectively reducing the risk of damage of the image acquisition assembly 200 and the inner door body 110 by high temperature, indirectly reducing the risk of damage of the outer door body 120 by high temperature, thereby improving the overall structural reliability and service life of the image acquisition assembly 200 and the cabinet door 100, improving the user's use experience, effectively meeting the market demand.

[0108] 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 exist contradictions, they should be considered as the scope of the present disclosure.

[0109] 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 noted 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 within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
