In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they contradict each other.

[0041] On one hand, an embodiment of the present application provides a cooking utensil, including a box body and a furnace door 1 of any embodiment of the present application.

[0042] It should be noted that the specific type of the cooking utensil is not limited here. For example, in some embodiments, the cooking utensil may be one of a microwave oven, an oven, an air fryer, and a steam oven. The present application embodiment is described by taking the cooking utensil as a microwave oven as an example.

[0043] In other embodiments, different functions can be integrated into the cooking appliance according to user needs, such as an all-in-one microwave steam oven, etc., to improve ease of use.

[0044] The housing has a cooking cavity and a take-out opening. It is understandable that the food to be cooked can enter the cooking cavity through the take-out opening, and the cooking cavity can be used to accommodate the food to be cooked.

[0045] The furnace door 1 is connected to the box body and is used to open or close the access opening.

[0046] It should be noted that the specific connection method between the oven door 1 and the box body is not limited. For example, the oven door 1 can be connected to the box body in a rotational manner, or the oven door 1 can be connected to the box body in a translational manner, as long as the oven door 1 can move relative to the box body to open or close the access opening. When the access opening is open, the user can take food into and out of the cooking cavity. When the cooking utensil is in a cooking state, the oven door 1 is in a state of closing the access opening.

[0047] Another aspect of the present application embodiment provides a cooking appliance door 1, please refer to Figures 1 to 3 The furnace door 1 includes a door body assembly 10 and a cooling device 20.

[0048] The door assembly 10 has an inner cavity (not shown in the figure). It can be understood that the inner cavity refers to the space formed by the structure of the door assembly 10 itself. When the oven door 1 closes the above-mentioned access opening, the inner cavity and the cooking cavity are not connected to each other, that is, the air in the cooking cavity will not enter the inner cavity.

[0049] It should be noted that the inner cavity can be a completely closed space, that is, the inner cavity does not exchange airflow with the external environment. In this state, the inner cavity can be filled with gas (such as air, inert gas, etc.), or it can be in a vacuum state. Of course, the inner cavity can also be connected to the external environment, that is, the inner cavity is filled with air, and the air pressure in the inner cavity is the same as the atmospheric pressure of the external environment.

[0050] The cooling device 20 is arranged in the inner cavity, and the cooling device 20 is used to accommodate the coolant. It is understandable that the cooling device 20 is located in the inner cavity, and the door body assembly 10 can provide installation space and installation position for the cooling device 20, and can also play a protective role. In addition, since the specific heat capacity of the coolant is large, it can absorb the heat of the door body assembly 10, and the temperature change of the coolant after the door body assembly 10 transfers the heat to the coolant is relatively small, which is conducive to reducing the temperature rise of the part of the door body assembly 10 near the cooling device 20 after being subjected to heat radiation.

[0051] In the related art, a heat dissipation duct and a heat dissipation fan are arranged on the furnace door, and the airflow is used to take away the heat on the furnace door to dissipate the heat of the furnace door. However, due to the sealing of the duct, this solution requires the formation of a special duct structure on the furnace door, and the structure of the furnace door needs to be customized, which not only makes the structure of the furnace door complicated, but also makes it impossible to make changes based on the existing furnace door.

[0052] The oven door 1 of the cooking appliance in the embodiment of the present application is provided with a cooling device 20 in the inner cavity of the oven door 1. By utilizing the large specific heat capacity of the coolant in the cooling device 20, the temperature of the coolant will not increase significantly after the coolant exchanges heat with the door body assembly 10, that is, the temperature rise of the coolant is small. The cooling device 20 can not only absorb the heat of the door body assembly 10, but also has a small temperature rise of its own, so that the temperature rise of the part of the door body assembly 10 located around the cooling device 20 is small when it is subjected to heat radiation. In addition, since the cooling device 20 is relatively independent, it is conducive to integrating the cooling device 20 in the inner cavity of the existing door body assembly 10, and it is convenient to install the cooling device 20 on the existing door body assembly 10, so as to realize the replacement of products on the basis of the existing door body at a lower cost.

[0053] In the oven door 1 of the cooking appliance of the embodiment of the present application, since the cooling device 20 is integrated in the inner cavity of the door body assembly 10, the cooling device 20 does not affect the appearance of the door body assembly 10. In addition, the cooling device 20 and the door body assembly 10 are integrated into a pre-assembled whole. During assembly, it is only necessary to install the pre-assembled whole on the box body. In this way, the assembly process is relatively simple, which is conducive to saving assembly time on the assembly line. It should be noted that, as a comparative example, if the pumping mechanism 21 is arranged on the outside of the door body assembly 10, for example, in the installation space inside the box body, then during assembly, it is also necessary to introduce the pipeline on the box body into the door body assembly 10, and the connection between the oven door 1 and the box body also needs to meet the pipe laying requirements, which increases the difficulty of pipe laying, increases the structural complexity and assembly difficulty, and may also affect the connection reliability between the oven door 1 and the box body.

[0054] It should be noted that the specific structure of the cooling device 20 is not limited.

[0055] In some embodiments, please refer to Figure 1 and Figure 2 The cooling device 20 includes a pumping mechanism 21 and a cooling pipeline 22 for the flow of coolant. The pumping mechanism 21 is connected to the cooling pipeline 22 to drive the coolant to flow in the cooling pipeline 22. It can be understood that the pumping mechanism 21 and the cooling pipeline 22 are both arranged in the inner cavity of the door body assembly 10. Driven by the pumping mechanism 21, the coolant can flow in the cooling pipeline 22. By utilizing the large specific heat capacity of the coolant itself, the coolant can absorb the heat of the door body assembly 10 located around the cooling device 20 during the flow process.

[0056] It should be noted that the specific structure of the pumping mechanism 21 is not limited, for example, it can be a power device such as a liquid pump.

[0057] It should be noted that the specific type of the coolant is not limited. For example, the coolant can be glycerin, alcohol, water, salt water or alkaline water.

[0058] In the embodiment of the present application, taking water as the coolant as an example, using water as the coolant is not only low-cost and easy to obtain, but also has a large specific heat capacity and is pollution-free. Even if leakage occurs, it will not endanger food safety.

[0059] In some embodiments, please refer to Figure 1 and Figure 2 The cooling device 20 includes a liquid storage tank 23, which is connected to the cooling pipeline 22 and is used to store coolant.

[0060] It can be understood that the coolant in the cooling line 22 can enter the liquid storage tank 23, and the coolant in the liquid storage tank 23 can also enter the cooling line 22. The liquid storage tank 23 can store more coolant. On the one hand, the coolant stored in the liquid storage tank 23 can be used as a supplementary liquid for the coolant flowing in the cooling line 22, so that the cooling line 22 has sufficient coolant to ensure that the cooling line 22 can continuously absorb the heat of the door body assembly 10; on the other hand, the coolant in the cooling line 22 can be mixed with the coolant in the liquid storage tank 23 after entering the liquid storage tank 23.

[0061] It should be noted that the specific shape of the liquid storage tank 23 is not limited, for example, it can be rectangular, circular or elliptical.

[0062] It should be noted that the number of the liquid storage tanks 23 is not limited. For example, the number of the liquid storage tanks 23 can be one or more, and more means two or more.

[0063] In some embodiments, please refer to Figure 1 and Figure 2 The cooling pipeline 22, the pumping mechanism 21, and the liquid storage tank 23 constitute at least a part of the coolant circulation passage. In this way, the coolant in the cooling device 20 can circulate in the cooling pipeline 22, the pumping mechanism 21, and the liquid storage tank 23, thereby improving the ability of the coolant to exchange heat, which is beneficial to reducing the temperature rise of the furnace door 1 due to heat radiation.

[0064] It should be noted that the coolant circulation passage refers to a channel in the cooling device 20 for circulating the coolant.

[0065] It should be noted that, in some embodiments, the cooling device 20 is equipped with a liquid storage tank 23, but not equipped with a cooling pipeline 22 and a pumping mechanism 21. In other embodiments, the cooling device 20 is not equipped with a liquid storage tank 23, but is equipped with a cooling pipeline 22 and a pumping mechanism 21. In still other embodiments, the cooling device 20 is equipped with a liquid storage tank 23, a cooling pipeline 22 and a pumping mechanism 21.

[0066] It should be noted that the specific type of the cooling pipeline 22 is not limited.

[0067] In some embodiments, the cooling pipe 22 is a metal pipe. It is understood that the metal pipe has a good heat transfer efficiency, which facilitates the heat exchange between the coolant in the metal pipe and the environment in the inner cavity, and facilitates the rapid removal of heat from the door assembly 10. In this embodiment, the metal pipe can be a hard pipe or a metal hose.

[0068] In some embodiments, the cooling pipe 22 is a flexible pipe. It is understandable that the flexible pipe is conducive to flexible arrangement, so that the space layout inside the furnace door 1 is compact. In addition, the flexible pipe can be bent multiple times to form an S-shaped curve arrangement, so that the cooling pipe 22 can cover as many areas as possible, so as to improve the cooling pipe 22 The effect of absorbing heat in the door assembly 10.

[0069] For example, please refer to Figures 3 to 5 The cooling pipeline 22 includes a liquid inlet pipe 222 and a liquid outlet pipe 221, the liquid storage tank 23 has a liquid outlet 23a and a liquid inlet, the pumping mechanism 21 has a pump inlet 21a and a pump outlet 21b, the liquid inlet pipe 222 connects the liquid inlet and the pump outlet 21b, and the liquid outlet 23a connects the liquid outlet 23a and the pump inlet 21a. It can be understood that the coolant flows from the liquid outlet 23a to the pump inlet 21a along the liquid outlet pipe 221, and after being driven by the pumping mechanism 21, the coolant flows from the pump outlet 21b to the liquid inlet along the liquid inlet pipe 222, and the coolant circulates back and forth in this way to form a coolant circulation passage, and absorbs the heat around the cooling pipeline 22 during the circulation process.

[0070] It should be noted that the specific routing path of the cooling pipeline 22 is not limited.

[0071] In the related art, a circuit board is arranged in the inner cavity of the oven door, and the circuit board is used to be electrically connected to the knobs, operating keys, etc. on the oven door. During the operation of the cooking appliance, the heat generated by the circuit board itself plus the heat radiated to the circuit board by the cooking cavity causes the circuit board to heat up seriously, which can easily lead to failure of the electronic components of the circuit board.

[0072] The oven door 1 of the cooking appliance of the present application embodiment, please refer to Figure 1 and Figure 2 The furnace door 1 includes a control circuit board 30 disposed in the inner cavity, and the pipe routing path of the cooling pipeline 22 passes through the control circuit board 30, which is used to cool the control circuit board 30. In this way, the coolant in the cooling pipeline 22 absorbs the heat near the control circuit board 30, so that the temperature rise of the control circuit board 30 is small, and the operation stability of the control circuit board 30 can be improved.

[0073] It should be noted that the piping path of the cooling pipe 22 passing through the control circuit board 30 means that: on the plane where the control circuit board 30 is located, the projection of the cooling pipe 22 partially overlaps with the projection of the control circuit board 30, or the projection of the cooling pipe 22 does not overlap with the projection of the control circuit board 30 and the spacing between the two is less than 10 mm.

[0074] In some embodiments, please refer to Figure 1 and Figure 2 The door assembly 10 has a light-transmitting window area. The user can observe the food in the cooking cavity through the light-transmitting window area, so that the cooking process can be visualized.

[0075] Exemplarily, the cooling pipe 22 surrounds the periphery of the light-transmitting window area. In this way, the user can hardly see the cooling pipe 22, which is also beneficial for the cooling pipe 22 to dissipate heat and cool the parts around the light-transmitting window area.

[0076] In some embodiments, please refer to Figure 3 and Figure 6 The door assembly 10 includes a door frame 11 and a panel 12, wherein the panel 12 is disposed on one side of the door frame 11 along a first direction. For example, the panel 12 is located on the front side of the door frame 11, and a user can see the panel 12. The middle area of ​​the door frame 11 has an opening 11a, and a mounting groove 11b is formed on one side of the door frame 11 facing the panel 12, and the mounting groove 11b surrounds the opening 11a.

[0077] The cooling device 20 is installed in the installation groove 11b. It is understandable that the cooling device 20 is located in the installation groove 11b, which can reasonably utilize the space of the installation groove 11b of the door assembly 10, and can minimize the increase in the thickness of the door assembly 10, thereby reducing the influence of the cooling device 20 on the appearance size of the furnace door 1.

[0078] The panel 12 covers the door frame 11 , and the panel 12 and the mounting groove 11 b form an inner cavity.

[0079] The opening 11a in the middle area of ​​the door frame 11 is located in the light-transmitting window area. It should be noted that the portion of the panel 12 corresponding to the opening 11a is light-transmitting, while the portion outside the opening 11a of the door frame 11 is light-impermeable.

[0080] It should be noted that the first direction refers to: Figure 3 The first direction is consistent with the thickness direction of the furnace door 1.

[0081] It should be noted that the specific location of the liquid storage tank 23 is not limited.

[0082] In some embodiments, the door assembly 10 further includes a handle, which is disposed on a side of the panel 12 away from the door frame 11. It is understandable that the user can apply force to the handle to drive the oven door 1 to move, so that the oven door 1 opens or closes the access opening, making it convenient for the user to take food from the cooking cavity.

[0083] For example, in the orthographic projection on the plane where the panel 12 is located, the projection of the handle overlaps at least partially with the projection of the liquid storage tank 23. It is understandable that the coolant stored in the liquid storage tank 23 can absorb heat, reduce the temperature rise of the components around the liquid storage tank 23, reduce the temperature rise of the panel 12 within the projection range of the liquid storage tank 23, and reduce the temperature rise of the connection between the panel 12 and the handle. In this way, when the user applies force to the handle, the risk of the user being scalded by the panel 12 around the handle can be reduced.

[0084] In some other embodiments, please refer to Figures 1 to 3 The local depression of the peripheral side wall of the door frame 11 forms a gripping position 11c. It is understandable that the user can apply force to the oven door 1 through the gripping position 11c to drive the oven door 1 to open or close the access opening, thereby facilitating the user to take food from the cooking cavity.

[0085] Exemplarily, the liquid storage tank 23 is located on a side of the gripping position 11c close to the inner cavity. That is, the liquid storage tank 23 is arranged near the gripping position 11c. In this way, the liquid storage tank 23 is conducive to reducing the temperature rise of the gripping position 11c after being subjected to heat radiation, thereby reducing the risk of the user being scalded when applying force to the gripping position 11c.

[0086] The cooling device 20 may be fixed in the door assembly 10 in any manner. For example, in some embodiments, bonding, bolting, or screwing may be used.

[0087] For example, in some embodiments, please refer to Figure 3 , Figure 6 and Figure 7 The door frame 11 has a pair of elastic hooks 111, and the free ends of the elastic hooks 111 have hook portions 111a, and the hook portions 111a of the pair of elastic hooks 111 face each other, and the pair of elastic hooks 111 are used to constrain at least a portion of the cooling device 20 therebetween. It can be understood that the elastic hooks 111 and the door frame 11 are an integral structure, for example, an integrally molded plastic part.

[0088] The elastic hook 111 can establish a connection between at least a portion of the cooling device 20 and the door frame 11 under the action of its own elastic force, which can reduce the possibility of the cooling device 20 being separated from the door frame 11 during the operation of the cooking appliance.

[0089] During assembly, only some parts of the cooling device 20 need to be pushed between the two pairs of elastic hooks 111, which is convenient for assembly. During disassembly, the free ends of the two elastic hooks 111 are broken apart, and some parts of the cooling device 20 can be taken out from between the two elastic hooks 111, which is convenient for disassembly.

[0090] For some specific embodiments, please refer to Figures 1 to 3 The door frame 11 has a plurality of elastic hooks 111 arranged in pairs, some of which are used to install the pumping mechanism 21, other pairs of which are used to install the liquid storage tank 23, and some pairs of which are used to install the cooling pipeline 22. In this way, the elastic hooks 111 can fix the pumping mechanism 21, the liquid storage tank 23 and the cooling pipeline 22 on the door frame 11, so as to reduce the possibility of the pumping mechanism 21, the liquid storage tank 23 and the cooling pipeline 22 being separated when the cooking appliance is running, so as to ensure the stable operation of the pumping mechanism 21, the liquid storage tank 23 and the cooling pipeline 22.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
