[0006] The cooking appliance provided by the utility model includes a housing, a door body, a driving member, a blowing device and a wind guiding cover. The housing includes a cooking cavity and an electrical appliance compartment. The driving member is arranged in the electrical appliance compartment and is opposite to the door body. The driving member can push the door body to open the cooking cavity, and after the door body opens the cooking cavity, an exhaust gap communicated with the cooking cavity can be formed between the door body and the housing, so as to discharge the steam or moisture in the cooking cavity, thereby adjusting the humidity or the amount of steam in the cooking cavity. The blowing device is used to blow air into the electrical appliance compartment to dissipate heat from the electrical components in the electrical appliance compartment. Among them, the wind guiding cover is arranged in the electrical appliance compartment and is communicated with the blowing device. Therefore, when the blowing device is turned on, the wind guiding cover can guide air to the driving member, realizing the cooling of the driving member, improving the heat dissipation effect of the driving member, and further ensuring the working performance of the driving member. At the same time, for the cooking appliance provided in this application, the blowing device can not only dissipate heat from the electrical components in the electrical appliance compartment, but also dissipate heat from the driving member, improving the utilization rate of the blowing device, and there is no need to separately set a heat dissipation structure for the driving member, thereby reducing the use of components, reducing the manufacturing cost, and reducing the overall volume of the cooking appliance.
[0007] According to the cooking appliance provided by the present utility model, the following additional technical features may also be included:
[0008] In some embodiments, optionally, the air guide cover includes: a cover body provided with a first opening, and a driving member disposed opposite to the cover body; a cover plate located at the first opening, the cover plate being movably connected to the cover body for opening or closing the first opening; wherein, when the air supply device is turned on, the cover plate closes the first opening, and the air supply device supplies air to the driving member through the cover body; when the air supply device is turned off, the cover plate opens the first opening, and at least a part of the cover body communicates with the electrical appliance compartment outside the cover body through the first opening, and the driving member dissipates heat through the first opening.
[0009] In this embodiment, the air guide cover includes a cover body and a cover plate. The cover body is provided with a first opening, and the cover plate is movably connected to the cover body, and thus can open or close the first opening. The cover body is used to guide air to the driving member. When the air supply device is turned on, the cover plate closes the first opening, and the cover body communicates with the air supply device, so that the cover body guides air to the driving member to achieve heat dissipation of the driving member and improve the heat dissipation efficiency of the driving member. When the air supply device is turned off, the cover plate opens the first opening, so that at least a part of the cover body communicates with the electrical appliance compartment outside the cover body through the first opening, and thus the driving member can perform static heat exchange with the air in the electrical appliance compartment through the first opening, so that when the air supply device is turned off, the temperature of the driving member can be ensured not to be too high, the reliability of the driving member during operation is improved, and the situation that the driving member accidentally opens the door body due to excessive temperature rise is avoided.
[0010] In some embodiments, optionally, the top wall of the cover body is inclined towards the driving member.
[0011] In this embodiment, the top wall of the cover body is inclined towards the driving member, and thus the wind speed flowing towards the driving member can be increased to quickly take away the heat of the driving member.
[0012] In some embodiments, optionally, the cooking appliance further includes: a heat insulation plate disposed in the electrical appliance compartment, the heat insulation plate being provided with a second opening, the driving member being disposed at the bottom of the heat insulation plate and opposite to the second opening, and the air guide cover covering the second opening; wherein, when the air supply device is turned on, the air supply device supplies air to the driving member through the second opening; when the air supply device is turned off, the first opening communicates with the second opening.
[0013] In this embodiment, the cooking appliance further includes a heat insulation plate disposed in the electrical appliance compartment to prevent the heat in the cooking cavity from being transferred to the electrical appliance compartment. The heat insulation plate is provided with a second opening, and the air guide cover is disposed over the second opening. The driving member is disposed at the bottom of the heat insulation plate and opposite to the second opening. In this way, when the air supply device is turned on, the cover plate closes the first opening, so that the air supply device communicates with the second opening through the cover body, and then the air supply device supplies air to the driving member through the second opening to cool the driving member; when the air supply device is turned off, the cover plate opens the first opening, so that the second opening communicates with the first opening through the cover body, and then the driving member can exchange heat with the air flow in the electrical appliance compartment outside the cover body through the first opening and the second opening to cool the driving member. That is, the driving member can be cooled whether the air supply device is turned on or off, thus ensuring the reliability of the driving member during operation.
[0014] In some embodiments, optionally, the first opening is provided in the top wall of the cover body, the cover plate is located inside the cover body and suspended from the top wall of the cover body, and the cover plate is located between the first opening and the air supply device; when the air supply device is turned off, the cover plate hangs down along the direction of gravity or the cover plate overlaps in the second opening to communicate the first opening and the second opening.
[0015] In this embodiment, the first opening is provided in the top wall of the cover body, and the cover plate is located inside the cover body and suspended from the top wall of the cover body, so that the cover plate can open the first opening under the action of gravity. At the same time, the cover plate is located between the air supply device and the first opening. When the air supply device is turned on, under the push of the air flow, the cover plate rotates upward, and then the cover plate closes the first opening. The air flow generated by the air supply device can flow through the cover body to the second opening, thereby dissipating heat from the driving member and increasing the air flow rate flowing to the driving member; when the air supply device is turned off, the cover plate rotates downward under the action of gravity, and then the cover plate opens the first opening, and the first opening communicates with the second opening, so that the driving member can exchange heat with the electrical appliance compartment outside the cover body, which is at a lower temperature and has a larger volume. Among them, when the air supply device is turned off, the cover plate can naturally hang down under the action of gravity, or can rotate downward under the action of gravity and then overlap in the second opening, thereby ensuring the reliability of the communication between the second opening and the first opening, and also enabling the cover plate to have a guiding effect, so that the air flow at the first opening enters the second opening along the cover plate to realize heat exchange with the driving member.
[0016] In some embodiments, optionally, the heat insulation plate includes a cooling air duct that communicates with the air supply device; the cooking appliance further includes a frequency converter disposed in the cooling air duct. The air guide cover communicates with the end of the cooling air duct away from the air supply device, and the air supply device supplies air into the air guide cover through the cooling air duct.
[0017] In this embodiment, a cooling air duct is provided on the heat insulation plate. Since the frequency converter generates a large amount of heat during operation, the frequency converter is arranged in the cooling air duct, so that a part of the air flow blown by the air supply device can concentrate on passing through the frequency converter in the cooling air duct to accelerate the heat dissipation efficiency of the frequency converter. The air guide cover is arranged at one end of the cooling air duct away from the air supply device, so that the air flow in the cooling air duct flows through the air guide cover to the driving part to dissipate heat for the driving part. This setting can not only ensure the air supply volume at the position where the driving part is located, but also avoid occupying the air supply volume of other components in the electrical appliance compartment for dissipating heat for the driving part.
[0018] In some embodiments, optionally, the air supply device includes a first air supply port and a second air supply port. The cooling air duct is communicated with the first air supply port, and the second air supply port is used for supplying air to the electrical appliance compartment outside the cooling air duct.
[0019] In this embodiment, the air supply device includes a first air supply port and a second air supply port. The cooling air duct is arranged opposite to the first air supply port. Then, the air supply device supplies air into the cooling air duct through the first air supply port to increase the air supply volume in the cooling air duct; the second air supply port supplies air to the electrical appliance compartment outside the cooling air duct to realize the heat dissipation of other components in the electrical appliance compartment.
[0020] In some embodiments, optionally, the driving part includes a wax motor.

[0022] In some embodiments, optionally, the wax motor includes a push rod, the push rod is arranged opposite to the door body, and the push rod is used for pushing the door body.
[0023] In this embodiment, the wax motor includes a push rod. After the wax motor is powered on, the solid wax inside the wax motor melts and expands, thereby driving the push rod to extend. The push rod pushes the door body to open the cooking cavity to realize the moisture or steam discharge of the cooking cavity.
[0024] In some embodiments, optionally, the door body is rotatably connected to the housing, and along the rotation axis direction of the door body, the driving part is arranged close to the middle of the housing.
[0025] In this embodiment, the door body is rotatably connected to the housing, and then the cooking cavity is opened by the rotation of the door body. The driving part is arranged close to the middle of the housing along the rotation axis direction of the door body. When the driving part pushes the door body open, the situation of pushing the door with eccentric load can be avoided, and further the door body can be prevented from being deformed by the driving part. When the cooking appliance cooks by microwave, the situation of microwave leakage can be avoided.
[0026] In some embodiments, optionally, an exhaust port is provided on the housing, both the air guide cover and the electrical appliance compartment are communicated with the exhaust port, and at least a part of the driving part is located between the air guide cover and the exhaust port.
[0027] In this embodiment, both the air guide cover and the electrical appliance chamber are in communication with the exhaust port. The air flow generated by the air supply device can flow out from the exhaust port after exchanging heat with the electrical components and the driving member in the electrical appliance chamber. By arranging at least a part of the driving member between the air guide cover and the exhaust port, the driving member can be continuously cooled, ensuring the reliability of the driving member during operation.

[0029] In this embodiment, arranging the electrical appliance chamber at the top of the cooking cavity is beneficial to improving the heat dissipation effect of the components in the electrical appliance chamber.

Specific embodiments
[0044] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0045] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.
[0046] The following refers to Figures 1 to 10 Describe the cooking appliance according to some embodiments of the present utility model.
[0047] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 And Figure 8As shown, according to an embodiment of the present utility model, the present utility model provides a cooking appliance, comprising: a housing 1, the housing 1 includes a cooking cavity 10 and an electrical appliance compartment 12, and the electrical appliance compartment 12 is arranged on one side of the cooking cavity 10; a door body 2, movably connected to the housing 1 and used to open or close the cooking cavity 10; a driving member 3, arranged in the electrical appliance compartment 12 and opposite to the door body 2, the driving member 3 is used to push open the door body 2 so that an exhaust gap 4 is formed between the door body 2 and the housing 1, and the exhaust gap 4 communicates with the cooking cavity 10; a blowing device 5, arranged in the housing 1 and used to blow air into the electrical appliance compartment 12; a wind guiding cover 6, arranged in the electrical appliance compartment 12, the wind guiding cover 6 communicates with the blowing device 5, and the wind guiding cover 6 is opposite to the driving member 3 and is used to guide air to the driving member 3.
[0048] The cooking appliance provided by the present utility model includes a housing 1, a door body 2, a driving member 3, a blowing device 5 and a wind guiding cover 6. The housing 1 includes a cooking cavity 10 and an electrical appliance compartment 12. The driving member 3 is arranged in the electrical appliance compartment 12 and opposite to the door body 2. The driving member 3 can push the door body 2 to open the cooking cavity 10. After the door body 2 opens the cooking cavity 10, an exhaust gap 4 communicating with the cooking cavity 10 can be formed between the door body 2 and the housing 1, thereby realizing the discharge of steam or moisture in the cooking cavity 10 to adjust the humidity or the amount of steam in the cooking cavity 10. The blowing device 5 is used to blow air into the electrical appliance compartment 12 to realize the heat dissipation of the electrical components in the electrical appliance compartment 12. Among them, the wind guiding cover 6 is arranged in the electrical appliance compartment 12 and communicates with the blowing device 5. Therefore, when the blowing device 5 is turned on, the wind guiding cover 6 can guide air to the driving member 3, realizing the cooling of the driving member 3, improving the heat dissipation effect of the driving member 3, and further ensuring the working performance of the driving member 3. At the same time, for the cooking appliance proposed in the present application, the blowing device 5 can not only realize the heat dissipation of the electrical components in the electrical appliance compartment 12, but also realize the heat dissipation of the driving member 3, improving the utilization rate of the blowing device 5, and there is no need to separately set a heat dissipation structure for the driving member 3, thereby reducing the use of parts, reducing the manufacturing cost, and reducing the overall volume of the cooking appliance.
[0049] It can be understood that the driving member 3 is arranged in the electrical appliance compartment 12. Through the setting of the wind guiding cover 6, the function of the blowing device 5 to blow air to the driving member 3 is realized, thereby increasing the air volume blown by the blowing device 5 to the driving member 3 and improving the heat dissipation effect of the driving member 3.
[0050] Optionally, the driving member 3 is a door-pushing exhaust device. A reset member is arranged between the door body 2 and the housing 1. At least a part of the driving member 3 can extend or retract from the housing 1. When at least a part of the driving member 3 extends out of the housing 1, the driving member 3 pushes open the door body 2 so that an exhaust gap 4 is formed between the door body 2 and the housing 1; when the driving member 3 retracts into the housing 1, the door body 2 is reset under the action of the reset member to close the cooking cavity 10.
[0051] Specifically, asFigure 1 As shown, when the driving member 3 pushes open the door body 2, an exhaust gap 4 is formed between the door body 2 and the housing 1.
[0052] As Figure 6 , Figure 7 , Figure 8 and Figure 9 shown, in some embodiments, optionally, the air guide cover 6 includes: a cover body 60 and a cover plate 62.
[0053] Specifically, a first opening 602 is provided on the cover body 60, and the driving member 3 is disposed opposite to the cover body 60; the cover plate 62 is located at the first opening 602, and the cover plate 62 is movably connected to the cover body 60 for opening or closing the first opening 602; wherein, when the air supply device 5 is turned on, the cover plate 62 closes the first opening 602, and the air supply device 5 supplies air to the driving member 3 through the cover body 60; when the air supply device 5 is turned off, the cover plate 62 opens the first opening 602, and at least a part of the cover body 60 communicates with the electrical appliance bin 12 outside the cover body 60 through the first opening 602, and the driving member 3 dissipates heat through the first opening 602.
[0054] In this embodiment, the air guide cover 6 includes a cover body 60 and a cover plate 62. A first opening 602 is provided on the cover body 60, and the cover plate 62 is movably connected to the cover body 60, so as to be able to open or close the first opening 602. The cover body 60 is used to guide air to the driving member 3. As Figure 6 and Figure 7 shown, when the air supply device 5 is turned on, the cover plate 62 closes the first opening 602, and the cover body 60 communicates with the air supply device 5, so that the cover body 60 guides air to the driving member 3, realizing the heat dissipation of the driving member 3 and improving the heat dissipation efficiency of the driving member 3 (the air flow flows along the Figure 7 direction of the arrow shown). As Figure 8 and Figure 9 shown, when the air supply device 5 is turned off, the cover plate 62 opens the first opening 602, so that at least a part of the cover body 60 communicates with the electrical appliance bin 12 outside the cover body 60 through the first opening 602, so that the driving member 3 can perform static heat exchange with the air in the electrical appliance bin 12 through the first opening 602, ensuring that the temperature of the driving member 3 will not be too high even when the air supply device 5 is turned off, improving the reliability of the driving member 3 during operation, and avoiding the situation that the driving member 3 accidentally operates to open the door body 2 due to excessive temperature rise (the air flow flows along the Figure 8 direction of the arrow shown).
[0055] It can be understood that since the air supply device 5 supplies air to the electrical appliance bin 12, the ambient temperature in the electrical appliance bin 12 is relatively low when the air supply device 5 is turned off. Therefore, when the driving member 3 exchanges heat with the air in the electrical appliance bin 12 through the first opening 602, the temperature of the driving member 3 can be reduced.
[0056] In some embodiments, optionally, the top wall of the cover 60 is inclined towards the driving member 3.
[0057] In this embodiment, the top wall of the cover 60 is inclined towards the driving member 3, thereby increasing the wind speed flowing towards the driving member 3 to quickly remove the heat of the driving member 3.
[0058] It can be understood that the top wall of the cover 60 is inclined towards the driving member 3, so that the cross-sectional area of the cover 60 gradually decreases from the direction away from the driving member 3 to the direction close to the driving member 3, thereby gradually increasing the wind speed and increasing the cooling rate of the driving member 3.
[0059] As Figures 6 to 10 shown, in some embodiments, optionally, the cooking appliance further includes: a heat insulation plate 7. The heat insulation plate 7 is disposed in the electrical appliance compartment 12. A second opening 70 is provided on the heat insulation plate 7. The driving member 3 is disposed at the bottom of the heat insulation plate 7 and is disposed opposite to the second opening 70. The air guide cover 6 covers the second opening 70; wherein, when the air supply device 5 is turned on, the air supply device 5 supplies air to the driving member 3 through the second opening 70; when the air supply device 5 is turned off, the first opening 602 communicates with the second opening 70.
[0060] In this embodiment, the cooking appliance further includes a heat insulation plate 7. The heat insulation plate 7 is disposed in the electrical appliance compartment 12 to prevent the heat in the cooking cavity 10 from being transferred to the electrical appliance compartment 12. A second opening 70 is provided on the heat insulation plate 7. The air guide cover 6 covers the second opening 70. The driving member 3 is disposed at the bottom of the heat insulation plate 7 and is disposed opposite to the second opening 70. Thus, as Figure 6 and Figure 7 shown, when the air supply device 5 is turned on, the cover plate 62 closes the first opening 602, so that the air supply device 5 communicates with the second opening 70 through the cover 60, and then the air supply device 5 supplies air to the driving member 3 through the second opening 70 to realize the cooling of the driving member 3; as Figure 8 and Figure 9 shown, when the air supply device 5 is turned off, the cover plate 62 opens the first opening 602, so that the second opening 70 communicates with the first opening 602 through the cover 60, and then the driving member 3 can exchange heat with the air flow in the electrical appliance compartment 12 outside the cover 60 through the first opening 602 and the second opening 70 to realize the cooling of the driving member 3, that is, the driving member 3 can be cooled both when the air supply device 5 is turned on and off, thereby ensuring the reliability of the operation of the driving member 3.
[0061] As Figures 6 to 10As shown, in some embodiments, optionally, the first opening 602 is provided in the top wall of the cover 60, the cover plate 62 is located inside the cover 60 and is suspended from the top wall of the cover 60, and the cover plate 62 is located between the first opening 602 and the air supply device 5; when the air supply device 5 is closed, the cover plate 62 hangs down along the direction of gravity or the cover plate 62 overlaps in the second opening 70 to communicate the first opening 602 and the second opening 70.
[0062] In this embodiment, the first opening 602 is provided in the top wall of the cover 60, and the cover plate 62 is located inside the cover 60 and is suspended from the top wall of the cover 60, so that the cover plate 62 can open the first opening 602 under the action of gravity. At the same time, the cover plate 62 is located between the air supply device 5 and the first opening 602. When the air supply device 5 is turned on, under the push of the air flow, the cover plate 62 rotates upward, so that the cover plate 62 closes the first opening 602, and the air flow generated by the air supply device 5 can flow through the cover 60 to the second opening 70, thereby dissipating heat for the driving member 3 and increasing the air flow rate flowing to the driving member 3; when the air supply device 5 is closed, the cover plate 62 rotates downward under the action of gravity, so that the cover plate 62 opens the first opening 602, and the first opening 602 communicates with the second opening 70, so that the driving member 3 can exchange heat with the electrical appliance compartment 12 which is at a lower temperature, has a larger volume and is located outside the cover 60. Among them, when the air supply device 5 is closed, the cover plate 62 can naturally hang down under the action of gravity, or can rotate downward under the action of gravity and then overlap in the second opening 70, thereby ensuring the reliability of the communication between the second opening 70 and the first opening 602, and also enabling the cover plate 62 to have a guiding effect, so that the air flow at the first opening 602 enters the second opening 70 along the cover plate 62 to realize heat exchange with the driving member 3.
[0063] It can be understood that when the air supply device 5 is closed, after the air flow pushing the cover plate 62 disappears, the cover plate 62 will rotate downward under the action of gravity. Thus, the cover plate 62 can be in a state of natural hanging, or can contact with other structures (such as the heat insulation plate 7) after rotating downward, and the cover plate 62 is limited by other structures to prevent the cover plate 62 from rotating randomly.
[0064] As Figures 5 to 10 shown, in some embodiments, optionally, the heat insulation plate 7 includes a cooling air duct 72, and the cooling air duct 72 is communicated with the air supply device 5; the cooking appliance further includes a frequency converter 8, the frequency converter 8 is arranged in the cooling air duct 72, the air guiding cover 6 is communicated with one end of the cooling air duct 72 far away from the air supply device 5, and the air supply device 5 supplies air into the air guiding cover 6 through the cooling air duct 72.
[0065] In this embodiment, a cooling air duct 72 is provided on the heat insulation plate 7. Since the frequency converter 8 generates a large amount of heat during operation, the frequency converter 8 is arranged in the cooling air duct 72, so that a part of the air flow blown out by the air supply device 5 can be concentrated to pass through the frequency converter 8 in the cooling air duct 72, thereby accelerating the heat dissipation efficiency of the frequency converter 8. The air guide cover 6 is arranged at one end of the cooling air duct 72 away from the air supply device 5, so that the air flow in the cooling air duct 72 flows to the driving member 3 through the air guide cover 6 to dissipate heat from the driving member 3. This setting can not only ensure the air supply volume at the position where the driving member 3 is located, but also avoid occupying the air supply volume of other components in the electrical appliance compartment 12 for dissipating heat from the driving member 3.
[0066] Optionally, when the air supply volume of the air supply device 5 is sufficient, the air guide cover 6 can be directly aligned with the air supply device 5 alone without using the cooling air duct 72, so as to dissipate heat from the driving member 3 alone.
[0067] As Figure 10 shown, in some embodiments, optionally, the air supply device 5 includes a first air supply port 50 and a second air supply port 52. The cooling air duct 72 is communicated with the first air supply port 50, and the second air supply port 52 is used for supplying air into the electrical appliance compartment 12 outside the cooling air duct 72.
[0068] In this embodiment, the air supply device 5 includes a first air supply port 50 and a second air supply port 52. The cooling air duct 72 is arranged opposite to the first air supply port 50. Then, the air supply device 5 supplies air into the cooling air duct 72 through the first air supply port 50 to increase the air supply volume in the cooling air duct 72; the second air supply port 52 supplies air into the electrical appliance compartment 12 outside the cooling air duct 72 to dissipate heat from other components in the electrical appliance compartment 12.
[0069] It can be understood that the cooling air duct 72 and the air guide cover 6 are arranged in the electrical appliance compartment 12. The first air supply port 50 supplies air into the cooling air duct 72. Then, the air flow flows through the cooling air duct 72 to the air guide cover 6, and the heat of the frequency converter 8 and the driving member 3 is dissipated through the first air supply port 50; the second air supply port 52 supplies air into the electrical appliance compartment 12 outside the cooling air duct 72 and the air guide cover 6, and then supplies air volume to other components in the electrical appliance compartment 12 to dissipate heat from other components.
[0070] In some embodiments, optionally, the driving member 3 includes a wax motor 30.
[0071] In this embodiment, the driving member 3 includes a wax motor 30, and the wax motor 30 extends and retracts to push the door body 2.
[0072] Optionally, the core of the wax motor 30 (such as the push rod 302) is a temperature sensing element, which will extend when the temperature reaches the starting temperature of the wax motor 30. If the temperature at the location of the wax motor 30 is too high, it will cause the door body 2 to be abnormally ejected without the need to push the door to drain moisture. For the cooking appliance proposed in this application, the airflow that cools the electrical components in the electrical appliance compartment 12 is diverted to the location of the wax motor 30, thereby continuously cooling the outer shell of the wax motor 30, ensuring that the temperature of the outer shell of the wax motor 30 does not become too high, and thus avoiding the abnormal extension of the wax motor 30. At the same time, when the wax motor 30 needs to retract, the retraction speed of the wax motor 30 is increased, the closing speed of the door is increased, and the cooking efficiency is thus improved.
[0073] As Figures 6 to 9 shown, in some embodiments, optionally, the wax motor 30 includes a push rod 302. The push rod 302 is disposed opposite to the door body 2, and the push rod 302 is used to push the door body 2.
[0074] In this embodiment, the wax motor 30 includes a push rod 302. After the wax motor 30 is powered on, the solid wax inside the wax motor 30 melts and expands, thereby driving the push rod 302 to extend. The push rod 302 pushes the door body 2 to open the cooking cavity 10, realizing the moisture or steam discharge of the cooking cavity 10.
[0075] As Figure 1 and Figure 4 shown, in some embodiments, optionally, the door body 2 is rotatably connected to the housing 1, and along the rotation axis direction of the door body 2, the driving member 3 is disposed close to the middle of the housing 1.
[0076] In this embodiment, the door body 2 is rotatably connected to the housing 1, and then the cooking cavity 10 is opened by the rotation of the door body 2. The driving member 3 is disposed close to the middle of the housing 1 along the rotation axis direction of the door body 2. When the driving member 3 pushes the door body 2, the situation of pushing the door with eccentric load can be avoided, and thus the door body 2 is prevented from being deformed by the driving member 3. When the cooking appliance cooks by microwave, the situation of microwave leakage can be avoided.
[0077] As Figure 1 and Figure 4 shown, in some embodiments, optionally, an exhaust port 14 is provided on the housing 1. The air guide cover 6 and the electrical appliance compartment 12 are both communicated with the exhaust port 14, and at least a part of the driving member 3 is located between the air guide cover 6 and the exhaust port 14.
[0078] In this embodiment, the air guide cover 6 and the electrical appliance compartment 12 are both communicated with the exhaust port 14. The airflow generated by the air supply device 5 can flow out from the exhaust port 14 after exchanging heat with the electrical components and the driving member 3 in the electrical appliance compartment 12. Setting at least a part of the driving member 3 between the air guide cover 6 and the exhaust port 14 can enable the driving member 3 to be continuously cooled, ensuring the reliability of the operation of the driving member 3.
[0079] In some embodiments, optionally, the electrical appliance chamber 12 is provided at the top of the cooking chamber 10, and the driving member 3 is provided at the top of the cooking chamber 10.
[0080] In this embodiment, the electrical appliance chamber 12 is arranged at the top of the cooking chamber 10, which is beneficial to improving the heat dissipation effect of the components in the electrical appliance chamber 12. The driving member 3 is arranged at the top of the cooking chamber 10, so that the driving member 3 uses the air supply device 5 for dissipating heat from the electrical appliance chamber 12 to dissipate heat, achieving the effect of multi-purpose use of one machine and making full use of the airflow conveyed by the air supply device 5.
[0081] Optionally, the cooking appliance includes a microwave oven, a steam box, an oven, a steam oven, a microwave steam oven integrated machine, etc.
[0082] In specific applications, the cooking appliance proposed in this application utilizes the cooling air duct 72 of the frequency converter 8 to assist in cooling the wax motor 30 in real time, achieving multi-purpose use of one machine without affecting the cooling effect of the frequency converter 8, making full use of wind energy, and thus ensuring that the wax motor 30 will not cause abnormal door jamming due to excessive temperature without affecting the door-opening moisture discharge effect.
[0083] Specifically, as Figure 1 shown, when the wax motor 30 performs the door jamming operation and moisture discharge is required, the wax motor 30 is powered on, and the push rod 302 of the wax motor 30 jams the door, so that the moisture in the cooking chamber 10 is discharged from the door gap, thereby achieving the purpose of moisture discharge.
[0084] As Figure 4 shown, the wax motor 30 is placed at a position slightly to the upper left in the middle, resulting in a smaller eccentric load, so that the deformation amounts on both left and right sides of the door body 2 are smaller, preventing microwave leakage in the microwave mode caused by the deformation of the door body 2.
[0085] When the wax motor 30 is placed above the cooking chamber 10, there is a situation of excessive temperature rise. The core of the wax motor 30 is a temperature sensing element, and when the temperature reaches the starting temperature of the wax motor 30, it will abnormally extend, resulting in the abnormal ejection of the door body 2 without the need for door-opening moisture discharge. At this time, the cooling air duct 72 for dissipating heat from the frequency converter 8 is diverted to the wax motor 30, and the wax motor 30 is placed at the air outlet of the cooling air duct 72, so as to continuously cool the outer shell of the wax motor 30 in real time and ensure that the temperature of the outer shell of the wax motor 30 does not become too high.
[0086] Specifically, an inclined air guide cover 6 is adopted. Through the air guide of the air guide cover 6, the cooling air in the cooling air duct 72 of the frequency converter 8 is guided to the wax motor 30. The air guide cover 6 includes a cover body 60 and a one-way valve cover plate (such as the cover plate 62). When the micro steam oven starts to work, the cross-flow fan (such as the air supply device 5) starts, and the heat dissipation air duct is opened. At this time, due to the action of the cooling air, the air pressure in the cover body 60 is higher than the external air pressure. Through the air pressure, the one-way valve cover plate is closed with the cover body 60, so as to realize air guiding, and guide the cooling air to the position of the wax motor 30 obliquely below. Finally, the cooling air is discharged through the exhaust port 14 on the front plate of the housing 1. The wax motor 30 is continuously cooled by the cooling air, so as to ensure that the temperature rise of the wax motor 30 will not be too high and avoid the failure of the wax motor 30 function. When the whole machine stops working after cooking, since the wax motor 30 is relatively close to the cooking cavity 10, the residual heat in the cooking cavity 10 will heat the wax motor 30, resulting in the risk of too high temperature rise of the wax motor 30. After the cross-flow fan stops working, the temperature in the electrical appliance compartment 12 is relatively low. At this time, the one-way valve cover plate droops naturally, so that the wax motor 30 can exchange heat with the low-temperature area in the electrical appliance compartment 12, so as to indirectly assist in cooling the wax motor 30 and ensure that the wax motor 30 will not have abnormal temperature rise.
[0087] In the cooking appliance proposed by this application, the wax motor 30 is placed at a position slightly to the left in the middle, which can effectively reduce the occurrence of uneven load on the door body 2, and greatly improve the original deformation of the door body 2; through the cooling air duct 72 of the frequency converter 8, the wax motor 30 is effectively cooled, so that the high temperature generated in the furnace cavity during the cooking process will not be transmitted to the wax motor 30, effectively preventing the failure of the wax motor 30 function. Through the one-way conduction structure (such as the cover plate 62) of the air guide cover 6, during the cooking process, the cooling air duct 72 can discharge the cooling air in time. After cooking, the one-way conduction mechanism is opened, and the wax motor 30 can directly have effective heat convection with the air above the heat insulation plate 7, so as to ensure that the residual heat in the cooking cavity 10 will not make the temperature of the wax motor 30 too high, and further avoid the abnormal protrusion of the wax motor 30. Through the setting of the one-way valve cover plate, the automatic switching of the air guiding of the air guide cover 6 and the static heat exchange mode with the external environment is realized, so that the cooling effect of the wax motor 30 is more obvious, the problem of abnormal ejection of the door body 2 caused by too high temperature rise is solved, and at the same time, the closing speed of the wax motor 30 is increased, so as to further improve the cooking rate.
[0088] Optionally, when the power of the cross-flow fan is large and the air volume is sufficient, a heat dissipation air duct can be separately introduced to assist in cooling the wax motor 30.
