[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] In the related art, the food cooking device usually stops working immediately after cooking is finished. However, at the end of cooking, since the heating source of the food cooking device has just stopped heating the food, the internal cavity of the food cooking device may still maintain a relatively high temperature for a certain period of time. However, at this time, the fan of the food cooking device has stopped working and cannot dissipate the heat of the camera inside the cavity which is still at a relatively high temperature, which may cause damage to the camera.

[0034] In response to the above-mentioned problems of food cooking equipment, especially embedded food cooking equipment, some related technologies provide an oven door air duct on the oven door of the embedded food cooking equipment, which is connected to the exhaust device of the embedded food cooking equipment, so as to use the suction force generated by the exhaust fan in the exhaust device during operation to force the outside cold air to enter the oven door air duct to cool the oven door. However, the cooling effect achieved by this cooling method is limited, and there is still a risk of the oven door being too hot and scalding the user, and it is impossible to specifically cool down the camera.

[0035] Based on any of the above technical problems, the present application provides a camera component, which additionally adds an independent fan to utilize the independent fan to specifically cool and dissipate heat of the camera.

[0036] See also Figure 1 , Figure 1 It is a schematic diagram of a camera assembly in some embodiments of the present application. The camera assembly 10 of this embodiment is arranged on a food cooking device, and the food cooking device 100 has a cavity for placing food.

[0037] Specifically, the camera assembly 10 at least includes a camera assembly 101, a heat dissipation channel 102 and a fan 103. The camera assembly 101 is located on the cavity and is used to photograph the food in the cavity; for example, the camera assembly 101 is arranged above the cavity, that is, the camera assembly 101 is located above the food in the cavity to photograph the food.

[0038] One end of the heat dissipation channel 102 is connected to the camera assembly 101; the fan 103 is arranged at the other end of the heat dissipation channel 102 and is arranged on the shell of the food cooking device 100, so that the fan 103 draws air from outside the food cooking device 100 and dissipates the heat of the camera assembly 101 through the heat dissipation channel 102.

[0039] Among them, the fan 103 is arranged on the shell of the food cooking device 100, so that the fan 103 can absorb air from outside the food cooking device 100; and the fan 103 is connected to the other end of the heat dissipation channel 102 to transmit the absorbed air to the camera component 101 through the heat dissipation channel 102, thereby achieving heat dissipation of the camera component 101.

[0040] In some embodiments, the food cooking device 100 may be an air fryer, an oven, or other kitchen appliances, which are not limited here.

[0041] In some embodiments, the fan 103 may be a centrifugal fan, an axial flow fan, a mixed flow fan, a centrifugal blower or others, which are not limited here.

[0042] The camera assembly 10 provided in some embodiments of the present application is arranged on a food cooking device 100. The food cooking device 100 has a cavity for placing food. The camera assembly 10 specifically includes: a camera assembly 101, a heat dissipation channel 102, and a fan 103. Among them, the camera assembly 101 is located on the cavity and is used to shoot the food in the cavity; one end of the heat dissipation channel 102 is connected to the camera assembly 101; the fan 103 is arranged at the other end of the heat dissipation channel 102 and is arranged on the housing of the food cooking device 100, so that the fan 103 draws air from outside the food cooking device 100 and dissipates the heat of the camera assembly 101 through the heat dissipation channel 102. Through the above method, on the one hand, the heat dissipation of the camera assembly 101 can be achieved, the damage rate of the camera assembly 101 can be reduced, and the cost can be saved; on the other hand, the fan 103 is arranged on the housing of the device, and the fan 103 can use the air outside the food cooking device 100 to dissipate the heat of the camera assembly 101, which is more convenient.

[0043] In some embodiments, see Figure 2 , Figure 2 2 is a schematic diagram of a camera assembly in some embodiments of the present application. The camera assembly 101 of this embodiment includes a camera 201 , a temperature detector 202 and a controller 203 .

[0044] The temperature detector 202 is coupled to the camera 201 , and is used to detect the temperature of the camera 201 . The temperature detector 202 may be a temperature probe, a thermometer, or other temperature measuring equipment, which is not limited here.

[0045] The controller 203 is coupled to the camera 201, the temperature detector 202 and the fan 103 respectively, and is used to generate a control signal based on the temperature of the camera 201, and control the fan 103 to operate through the control signal, so that the fan 103 draws air from outside the food cooking device 100. In addition, the controller 203 can also be used to control the camera 201 to shoot food.

[0046] The camera assembly 101 provided in some embodiments of the present application can dynamically control the operation of the fan 103 according to the temperature of the camera 201, that is, when the temperature of the camera 201 increases / decreases, the wind force of the fan 103 can be synchronously increased / decreased, and the fan 103 can be used purposefully to reduce the waste of power resources. In addition, the fan 103 can be dynamically controlled according to the temperature of the camera 201 to improve the efficiency of the fan 103.

[0047] In some embodiments, the temperature detector 202 can monitor the real-time temperature of the camera 201 in real time, and send the real-time temperature of the camera 201 to the controller 203, so that the controller 203 can adjust the working parameters of the fan 103 in real time, and make the fan 103 work based on the adjusted working parameters. The working parameters include at least the running time and the rotation speed.

[0048] In one application scenario, the camera assembly 101 integrates the camera 201, the temperature probe and the controller 203. The temperature probe monitors the temperature of the camera 201 in real time, and sends the acquired real-time temperature to the controller 203. The controller 203 collects the control signal corresponding to the real-time temperature based on the received real-time temperature, and controls the fan 103 to work according to the preset rules. The fan 103 draws air from outside the food cooking device and dissipates the heat of the camera assembly 101 through the heat dissipation channel 102. Based on this, closed-loop control is realized, that is, when the temperature of the camera 201 is monitored, the camera can be fully cooled to ensure that the camera 201 can work within a safe temperature range.

[0049] In some embodiments, the preset rule is related to the control signal, and the corresponding instruction can be determined based on the control signal, and the fan 103 can be controlled to work based on the corresponding instruction. For example, the instruction corresponding to the control signal is to work at a speed of 3r / s (i.e., three revolutions per second), and the fan 103 will rotate at a speed of 3r / s; for another example, the instruction corresponding to the control signal is to rotate at a frequency of 50Hz, and the fan 103 will rotate at a frequency of 50Hz.

[0050] In some embodiments, the control signal includes the running time and the rotation speed of the fan 103; the controller 203 controls the operation of the fan 103 based on the running time, and controls the operation of the fan 103 based on the rotation speed.

[0051] The running time and speed of the fan 103 can be determined according to the temperature of the camera 201 detected by the temperature detector 202. At this time, the fan 103 can be started to work at the same time when the food cooking device 100 is started, or it can be started to work when the temperature of the camera 201 detected by the temperature detector 202 exceeds a preset threshold, wherein the value of the preset threshold can be determined through multiple experiments, and it is worth noting that the preset threshold is related to the safe working temperature of the camera 201. In one application scenario, the preset threshold is equal to the safe working temperature.

[0052] Alternatively, the running time and speed of the fan 103 can also be determined according to parameters such as the cooking time and cooking power used to cook the food in the cavity, that is, the running time and speed of the fan 103 can be determined by the user setting. At this time, the fan 103 can be started to work at the same time when the food cooking device 100 is started, or it can be started to work when the temperature of the camera 201 detected by the temperature detector 202 exceeds a preset threshold, wherein the value of the preset threshold can be determined through multiple experiments, and it is worth noting that the preset threshold is related to the safe working temperature of the camera 201. In one application scenario, the preset threshold is equal to the safe working temperature.

[0053] In some embodiments, due to different manufacturers, even if the same type of products are manufactured, there will be differences in performance. Therefore, the safe temperature range corresponding to the camera 201 used in this application is determined according to actual conditions. For example, the safe operating temperature range of the camera 201 is 50-60°C, that is, the operating temperature of the camera 201 is 50°C, 51°C, 52°C, 54°C, 55°C or 60°C, etc.; for another example, the safe operating temperature range of the camera 201 is 70-80°C, that is, the operating temperature of the camera 201 is 70°C, 71°C, 72°C, 74°C, 75°C or 80°C, etc.

[0054] In some embodiments, see Figure 3 , Figure 3 1 is a schematic diagram of a food cooking device 100 in some embodiments of the present application, specifically a left view of the food cooking device 100, the food cooking device 100 includes an oven door 1001, food is placed in a cavity A through the oven door 1001, a camera 201 is arranged close to the oven door 1001, and the camera 201 forms an angle X with the oven door 1001, and the angle of the angle X is an acute angle. That is, the angle range of the angle X is (0°, 90°), for example, the angle is 10°, 15°, 20°, 30°, 45°, 65°, 70°, 80°, etc.

[0055] In one application scenario, the camera 201 is arranged above the cavity A and has a certain inclination. The camera 201 and the furnace door 1001 do not contact each other. Along the extension direction of the camera 201, an angle X is obtained between the camera 201 and the furnace door 1001, and the angle X is 30°. In another application scenario, the camera 201 is arranged above the cavity A and has a certain inclination. The camera 201 and the furnace door 1001 do not contact each other. Along the extension direction of the camera 201, an angle X is obtained between the camera 201 and the furnace door 1001, and the angle X is 60°.

[0056] It is worth noting that when the camera 201 is set above the cavity A, the inclination of the camera 201 needs to be considered based on the user's observation angle, that is, it is necessary to ensure that the picture taken by the camera 201 is consistent with the food observed by the user through the window on the oven door 1001 of the food cooking device 100. For example, when the food cooking device 100 is placed far below the height of the user, the user needs to bend down to observe, or stand up straight and look diagonally downward. If the user stands up straight and looks diagonally downward, the angle X between the camera 201 and the oven door 1001 will approach 0°; if the user bends down to observe, the user and the food cooking device 100 are basically level in the horizontal direction, and the angle X between the camera 201 and the oven door 1001 will approach 90°.

[0057] In some embodiments, the user can set the inclination of the camera 201 through the operation panel of the food cooking device 100, that is, set the angle X between the camera 201 and the oven door 1001. For example, the angle X is set to 15°, 30°, 45° or 65°.

[0058] In some embodiments, Figure 3 As shown, the camera assembly 101 is arranged above the cavity A, the camera assembly 101 is arranged close to the furnace door 1001, and the camera assembly 101 forms an angle Y with the furnace door 1001, and the angle Y is an obtuse angle. That is, the angle range of the angle Y is (90°, 180°), for example, the angle is 95°, 100°, 110°, 120°, 145°, 165°, 170°, etc.

[0059] In one application scenario, the camera assembly 101 is arranged above the cavity A and has a certain inclination. The camera assembly 101 and the furnace door 1001 do not contact each other. Along the extension direction of the camera assembly 101, an angle Y between the camera assembly 101 and the furnace door 1001 is obtained, and the angle Y is 120°. In another application scenario, the camera assembly 101 is arranged above the cavity A and has a certain inclination. The camera assembly 101 and the furnace door 1001 do not contact each other. Along the extension direction of the camera assembly 101, an angle Y between the camera assembly 101 and the furnace door 1001 is obtained, and the angle Y is 60°.

[0060] It is worth noting that when the camera assembly 101 is set above the cavity A, the setting of the camera assembly 101 needs to ensure that the picture taken by the camera 201 in the camera assembly 101 is consistent with the food observed by the user through the window on the oven door 1001 of the food cooking device 100.

[0061] In some embodiments, Figure 3As shown, there are shielding objects between the camera assembly 101 and the fan 103. These shielding objects may be components such as a bottom plate, a motor or a magnetron, which makes the shape of the heat dissipation channel 102 bend to a certain extent, and it is impossible to directly connect the camera assembly 101 and the fan 103 in a straight line. In addition, when the camera assembly 101 is arranged above the cavity A, there is a certain inclination, which also makes it impossible for the heat dissipation channel 102 to directly connect the camera assembly 101 and the fan 103 in a straight line.

[0062] In other embodiments, without considering the user's perspective, the camera 201 is disposed close to the oven door 1001, and the camera 201 can be parallel to the oven door 1001, that is, the camera 201 can shoot the food at an angle perpendicular to the food in the cavity A. At this time, if there is no obstruction between the camera assembly 101 and the fan 103, the shape of the heat dissipation channel 102 can be a straight path without any bends.

[0063] In some embodiments, see Figure 3 The fan 103 is arranged on the side of the housing, and the side of the housing is arranged opposite to the oven door 1001. In an application scenario, the oven door 1001 is arranged on the front of the food cooking device 100, and the fan 103 is arranged on the back of the food cooking device 100.

[0064] In other embodiments, the fan 103 is also disposed on the right side wall or the left side wall of the food cooking device 100 , and in this case, the right side wall or the left side wall is in contact with the oven door 1001 .

[0065] The fan 103 in the camera assembly 10 provided in some embodiments of the present application is only used to cool down the camera 201 in the camera assembly 101. The fan 103 used at this time can be a low-power fan to reduce power consumption. In addition, to a certain extent, the noise generated by the low-power fan when working is less than that of the high-power fan. Therefore, when the fan 103 in the camera assembly 10 is a low-power fan, on the one hand, the power is small, the resources consumed are also small, which can save resources and costs; on the other hand, the noise generated is small, which can improve the user experience.

[0066] In some embodiments, see Figure 4 The heat dissipation channel 102 includes a first air duct 401, a second air duct 402 and a third air duct 403 which are connected in sequence. The first air duct 401 is connected to the fan 103, and the third air duct 403 is connected to the camera assembly 101. A first angle Z1 is formed between the first air duct 401 and the second air duct 402, and a second angle Z2 is formed between the second air duct 402 and the third air duct 403.

[0067] In some embodiments, the magnitudes of the first angle Z1 and the second angle Z2 can be determined according to the placement of the camera assembly 101 and the fan 103. For example, the camera assembly 101 and the fan 103 are located on the same horizontal line, and there is no other obstruction in the heat dissipation channel 102 between the two. At this time, the first air duct 401, the second air duct 402, and the third air duct 403 included in the heat dissipation channel 102 can form a "1"-shaped structure, and the first angle Z1 and the second angle Z2 approach 0°.

[0068] For another example, the camera assembly 101 and the fan 103 are located at the same horizontal line, and the heat dissipation channel 102 between the two is blocked by other objects, such as components such as motors. The existence of the blocking object makes it impossible for the heat dissipation channel 102 to be located at the same horizontal line as the camera assembly 101 and the fan 103. In this case, Figure 4 As shown, the first air duct 401, the second air duct 402 and the third air duct 403 included in the heat dissipation channel 102 can form an "arch bridge" structure, the first angle Z1 ranges from 0 to 90 degrees, and the second angle Z2 ranges from 90 to 180 degrees.

[0069] For another example, the camera assembly 101 and the fan 103 are not on the same horizontal line. For example, the camera assembly 101 is lower than the fan 103. At this time, the first air duct 401, the second air duct 402 and the third air duct 403 included in the heat dissipation channel 102 can form a "Z"-shaped structure, and the value range of the first angle Z1 is 0 to 90°, and the value range of the second angle Z2 is 0 to 90°.

[0070] In some embodiments, the materials, lengths, widths, and other data used by the first air duct 401, the second air duct 402, and the third air duct 403 can be determined according to actual conditions. For example, the distance between the camera assembly 101 and the closest obstruction (denoted by a) is set to the length of the third air duct 403, the distance between the fan 103 and the closest obstruction (denoted by b) is set to the length of the first air duct 401, and the distance between obstruction a and obstruction b is set to the length of the second air duct 402. Among them, obstruction a is the obstruction between the camera assembly 101 and the fan 103 that is closest to the camera assembly 101, and obstruction b is the obstruction between the camera assembly 101 and the fan 103 that is closest to the fan 103.

[0071] In some embodiments, the first air duct 401, the second air duct 402 and the third air duct 403 included in the heat dissipation channel 102 are integrally formed, and the three are made of the same material; the first air duct 401, the second air duct 402 and the third air duct 403 included in the heat dissipation channel 102 are made of different materials.

[0072] In some embodiments, the heat dissipation channel 102 includes an air duct, which is arc-shaped and is used for circulating air.

[0073] In some embodiments, see Figure 5 , Figure 5 1 is a schematic diagram of a food cooking device 100 in some embodiments of the present application, specifically a top view of the food cooking device 100, a fan 103 is arranged in the middle part of the back of the food cooking device 100, the fan 103 is placed on the fan bottom plate, and in space, the camera assembly 101 is arranged above the cavity A opposite to the middle part of the oven door 1001. The fan 103 and the camera assembly 101 are arranged opposite to each other, and the heat dissipation channel 102 therebetween is in the shape of "1", but in the side view, the heat dissipation channel 102 may be in the shape of "1", "arch bridge", "Z" or other structures.

[0074] In some embodiments, Figure 5 As shown, there is a shielding object H above the cavity A and below the heat dissipation channel 102, and the shielding object H may be a motor, a sensor or other devices.

[0075] The camera assembly 10 provided in some embodiments of the present application can achieve heat dissipation for the camera assembly 101, reduce the damage rate of the camera assembly 101, and thus save costs; the fan 103 is arranged on the housing of the device, and the fan 103 can use the air outside the food cooking device 100 to dissipate heat for the camera assembly 101, which is more convenient.

[0076] In addition, it is worth noting that, in addition to the fan 103 in the camera assembly 10, the food cooking device 100 also includes a fan B (not shown in the figure, to distinguish it from the fan 103, it is represented by "B" in the description), and the fan B can be set on the oven door 1001, on the side of the shell, or other parts of the food cooking device 100. When the food cooking device 100 is started, the fan B also starts to start, and when the food cooking device 100 is shut down, the fan B is also shut down synchronously, that is, the fan B is used to cool down and dissipate heat for the camera 201 when the food cooking device 100 cooks the food placed in the cavity A.

[0077] In other words, the fan B will dissipate heat to the camera 201 only when the food cooking device 100 is working. However, after the food cooking device 100 is turned off, the temperature in the cavity A will drop after a period of time, rather than immediately, and the camera 201 is still in a high temperature environment.

[0078] Based on this, the fan 103 in the camera assembly 10 provided in some embodiments of the present application is an independent fan, which can cool down and dissipate heat for the camera 201 in the camera assembly 101 after the food is cooked, thereby solving the problem of overheating of the camera 201. In addition, in some embodiments of the present application, the independent fan has low power and noise and is located on the side of the housing of the food cooking device 100, which can not only improve the user experience, but also save resources and costs.

[0079] See also Figure 6 , Figure 6 1 is a schematic diagram of a food cooking device in some embodiments of the present application, wherein the food cooking device 100 comprises a housing 601 and a camera assembly 10. The housing 601 is provided with a cavity A, and the cavity A is used to place food; the camera assembly 10 is provided in the cavity A, and is used to photograph the food in the cavity A. The camera assembly 10 is the same or similar to the camera assembly 10 described in any of the above embodiments, and will not be described in detail here.

[0080] In some embodiments, the food cooking device 100 further includes an oven door 1001 ; one end of the camera assembly 10 is close to the oven door 1001 , and the other end of the camera assembly 10 is close to a side surface of the food cooking device 100 , wherein the side surface is arranged opposite to the oven door 1001 .

[0081] In other embodiments, the food cooking device 100 may also include sensors, motors, operation panels, steam generators and other devices, which are not described in detail here.

[0082] In summary, the camera assembly 10 provided in the present application can achieve heat dissipation for the camera assembly 101, reduce the damage rate of the camera assembly 101, and thus save costs; further, the fan 103 is arranged on the housing of the device, and the fan 103 can use the air outside the food cooking device 100 to dissipate heat for the camera assembly 101, which is more convenient.
