Description

Technical Field

[0001] This invention relates to the field of electrical appliance technology, and more particularly to a cooking device. Background Technology

[0002] Household appliances such as dishwashers and steam ovens typically consist of a body with an inner cavity and a door that is mounted on the body. The door allows for the selective opening and closing of items inside the cavity. To prevent the appliance from being opened arbitrarily while in use, the body is usually equipped with a door lock device, and the door has a locking mechanism. When the door is closed, the locking mechanism engages with the door lock device to lock the door.

[0003] To achieve automatic door opening and closing, existing door lock devices typically include a drive motor and a locking mechanism. The locking mechanism cooperates with a locking component on the door, and the drive motor drives the locking mechanism to switch between an unlocked position (unlocked from the locking component) and a locked position (disengaged from the locking component). Since the drive motor generates heat during operation, if this heat is not dissipated in time, it can easily accumulate, affecting the reliability of the drive motor and consequently the safety of the door lock device.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0048] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0050] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0051] This embodiment provides a cooking device that enables automatic door opening and closing control while improving the safety and reliability of the cooking device and enhancing its performance. The cooking device is a steam cooking device, which may be, but is not limited to, an electric steamer or a steam oven.

[0052] like Figures 1 to 5 As shown, in this embodiment, the cooking equipment includes a body, a door 10, and a door lock device 1. The body includes a casing 6, an inner liner 30 located inside the casing 6, a fan shroud 2 and a cooling fan 5 located on top of the inner liner 30. The fan shroud 2 has an exhaust duct 23 communicating with the inner cavity of the inner liner 30. The cooling fan 5 guides external cooling airflow towards the exhaust duct 23. The door 10 is movably mounted on the front side of the body and has a locking component 9 at its top. The door lock device 1 includes a door lock drive assembly 11 and a door lock assembly 13 connected by a transmission connection. The door lock drive assembly 11 is located inside the body, and the door lock assembly 13 partially extends out from the front side of the fan shroud 2. The door lock drive assembly 11 drives the door lock assembly 13 to lock or unlock with the locking component 9.

[0053] During the cooking process, the door lock assembly 13 and the lock component 9 work together to lock the door 10 relative to the body, preventing steam from leaking out of the inner pot 30. When it is necessary to release the hot steam in the inner pot 30 during or after cooking, the hot steam is released into the exhaust duct 23 and discharged outward through the exhaust duct 23. At the same time, the cooling fan 5 guides the external cooling airflow into the exhaust duct 23, which helps to condense and cool the hot steam in the exhaust duct 23, thereby reducing the steam discharge temperature and preventing the discharged hot steam from scalding the user.

[0054] In this embodiment, the cooking device also includes an air guide structure that extends at least partially into the exhaust duct 23 to guide a portion of the cooling airflow in the exhaust duct 23 toward the door lock drive assembly 11.

[0055] The cooking device provided by the present invention guides the cooling airflow in the exhaust duct 23 to the door lock drive assembly 11 through a wind-guiding structure. This allows the cooling airflow to dissipate heat and cool the door lock drive assembly 11, preventing heat accumulation and improving the safety and reliability of the door lock drive assembly 11. At the same time, since the cooling airflow guided by the wind-guiding structure is formed by the original air shroud 2 and cooling fan 5 of the cooking device, it can effectively utilize the original structure of the cooking device to dissipate heat and cool the door lock drive assembly 11, reducing the improvement cost and difficulty of the cooking device, simplifying the structure of the cooking device, and improving the structural compactness of the cooking device.

[0056] In this embodiment, to simplify the exhaust structure of the cooking equipment, an exhaust port 25 is formed on the front side of the fan hood 2, and the front end of the exhaust duct 23 communicates with the exhaust port 25. Specifically, the casing 6 also includes a front frame surrounding the front side of the inner pot 30, a top support plate 62 installed on the top of the inner pot 30 and connected to the front frame at its front end, a door frame surrounding the outside of the front frame, and a casing 61 forming the outer shell of the machine body. The fan hood 2 is installed above the top support plate 62. The machine body also includes a control panel 8, which is installed on the upper front side of the door frame via a panel bracket 81, and the lower rear side of the control panel 8 overlaps with the front rear side of the fan hood 2.

[0057] The control panel 8 extends forward from the front of the inner pot 30. When the door 10 is closed, the top of the door 10 is spaced below the control panel 8, forming an exhaust gap between them. The exhaust port 25 is positioned directly opposite the exhaust gap. Preferably, multiple exhaust ports 25 are spaced apart along the left-right direction. Furthermore, the cooking equipment includes a main control board 20, which is mounted above the fan hood 2. The control panel 8 and the door lock drive assembly 11 are both communicatively connected to the main control board 20.

[0058] The door lock assembly 13 is installed in the middle of the machine body along the left-right direction, and the lock component 9 is located in the middle of the door 10 along the left-right direction. This improves the force balance and stability of the door 10 when opening and closing. The door lock drive assembly 11 is preferably installed at one end of the machine body along the left-right direction to avoid interference problems caused by having too many components in the middle area of ​​the top of the machine body, thus improving the rationality of the structural layout within the cavity at the top of the machine body. The door lock drive assembly 11 drives the door lock assembly 13 to switch between the unlocked and locked positions via the transmission assembly 12. The transmission assembly 12 extends along the left-right direction.

[0059] In this embodiment, the door lock device 1 includes a lock base 15, and the door lock assembly 13 includes a vertically arranged lock shaft and a door hook connected to the lower end of the lock shaft. The lock shaft is rotatably mounted on the lock base 15 around its own axis, and its lower end extends downward through the panel bracket 81, so that the door hook is located on the front side of the hood 2 and below the control panel 8, which facilitates the cooperation between the door lock assembly 13 and the lock component 9. In other embodiments, the door lock assembly 13 includes a door hook, the rear end of which is located in the top cavity and rotatably mounted on the lock base 15, and the front end of which extends through the lower side of the panel bracket 81 to be located on the front side of the hood 2. The specific structure of the door lock assembly 13 can adopt the door lock structure in the prior art, which is not the focus of this embodiment and will not be described in detail here.

[0060] The door lock device 1 includes a drive base 14, which is installed inside the body, and the door lock drive assembly 11 is installed on the drive base 14. The drive base 14 and the lock base 15 are separately arranged to facilitate the modular arrangement of the door lock device 1.

[0061] The door lock device 1 also includes a transmission component 12 connected between the door lock drive component 11 and the door lock component 13. The door lock drive component 11 drives the transmission component 12 to move in the left and right direction to push the door lock component 13 to rotate around an axis, so as to realize the switching of the door lock component 13 from the locked position to the unlocked position.

[0062] In this embodiment, the door lock drive assembly 11 includes a door lock drive component 11 and a cam 112. The transmission assembly 12 includes a slider 121 and a connecting rod 122. The motor shaft of the door lock drive motor 111 is connected to the cam 112 to drive the cam 112 to rotate. The slider 121 is slidably mounted on the drive seat 14. The two ends of the connecting rod 122 are respectively hinged to the slider 121 or the door lock assembly 13. The rotation of the cam 112 pushes the slider 121 to slide in the left-right direction towards the door lock assembly 13, thereby driving the connecting rod 122 to move and push the door lock assembly 13 from the locked position to the unlocked position. A connecting plate is provided at the upper end of the lock shaft, and the connecting rod 122 is connected to the connecting plate. Further, the door lock device 1 includes a door lock reset component, which is used to cause the door lock assembly 13 to return from the unlocked position to the locked position.

[0063] It is worth noting that the specific structures of the transmission component 12 and the door lock drive component 11 described above are merely exemplary structures. Any existing structure that enables the door lock drive component 11 to drive the transmission component 12 to rotate and thus the door lock component 13 can be applied to this invention. However, this is not the focus of the improvement of this invention and will not be elaborated here.

[0064] Furthermore, the panel bracket 81 includes a vertically arranged front bracket plate 812, a base bracket plate 811 connected to the lower side of the front bracket plate 812, a top bracket plate connected to the upper side of the front bracket plate 812, and side bracket plates connected to the left and right sides of the front bracket plate 812. The side bracket plates are connected to the door frame. In this embodiment, the rear end of the base bracket plate 811 is mounted on the upper front end of the hood 2, the lock seat 15 is installed on the base bracket plate 811, and the lock shaft extends downward through the base bracket plate 811.

[0065] To further improve the airflow and heat dissipation effect of the door lock drive assembly 11, the drive base 14 has a mounting cavity 143, in which the door lock drive assembly 11 is at least partially located. The airflow guide structure directs the cooling airflow toward the mounting cavity 143. By providing the mounting cavity 143 within the drive base 14 and directing the cooling airflow toward the mounting cavity 143, the cooling airflow exiting the air shroud 2 can be concentrated, preventing the cooling airflow exiting the air shroud 2 from flowing to other locations.

[0066] Furthermore, a detection sensor 40 is also provided in the installation cavity 143. The detection sensor 40 is used to detect the operating status of the door lock drive assembly 11 in order to better meet the control requirements of the door lock device 1.

[0067] The drive base 14 is mounted above the fan cover 2. A heat dissipation vent 1421 is provided at the bottom of the mounting cavity 143. The heat dissipation vent 1421 and the air intake vent 221 are directly opposite each other and connected. A corresponding air intake vent 221 is provided on the upper side of the fan cover 2. At least part of the air guiding structure passes through the heat dissipation vent 1421 and the air intake vent 221, guiding the cooling airflow sequentially through the air intake vent 221 and the heat dissipation vent 1421 and into the mounting cavity 143. By partially inserting the air guiding structure through the heat dissipation vent 1421 and the air intake vent 221, the cooling airflow in the exhaust duct 23 can be better guided to flow into the mounting cavity 143, thereby improving the guiding effect of the air guiding structure on the cooling airflow and thus improving the cooling effect of the cooling airflow on the door lock drive assembly 11.

[0068] To improve the ease of installation of the door lock drive assembly 11, the drive base 14 includes a base 142 and a top cover 141. The base 142 has an open groove, and the top cover 141 covers the opening of the groove. The top cover 141 and the base 142 together form an installation cavity 143. The top cover 141 is detachably connected to the base 142, thereby allowing the disassembly and assembly of the internal structure of the installation cavity 143 by removing and installing the top cover 141 relative to the base 142. The base 142 is detachably mounted on the main body.

[0069] Furthermore, a ventilation opening 1411 is provided on the upper side of the drive base 14. The door lock drive assembly 11 includes a door lock drive motor 111, which is mounted on the outside of the drive base 14. The output shaft of the door lock drive motor 111 extends into the mounting cavity 143 through the ventilation opening 1411. The heat dissipation vent 1421 is arranged vertically opposite to the ventilation opening 1411. The transmission assembly 12 is partially located inside the mounting cavity 143 to cooperate with the motor shaft of the door lock drive motor 111. By mounting the door lock drive motor 111 on the outside of the drive base 14, the space requirement of the mounting cavity 143 can be reduced, and the heat dissipation of the door lock drive motor 111 is more convenient. At the same time, by providing a ventilation opening 1411 on the upper cover 141, the cooling airflow flowing into the mounting cavity 143 can flow upward through the ventilation opening 1411, thereby dissipating heat from the main structure of the door lock drive motor 111.

[0070] To ensure effective heat dissipation, the diameter of the vent 1411 is at least four times the diameter of the output shaft, so that there is a sufficient path for cooling airflow between the side wall of the vent 1411 and the output shaft, thus ensuring effective cooling of the door lock drive motor 111.

[0071] Furthermore, the air guiding structure includes an air guide plate assembly 3, which includes a first air guide plate 31. The first air guide plate 31 passes through the heat dissipation vent 1421 and the air intake vent 221. The upper end of the first air guide plate 31 is located in the mounting cavity 143, and the lower end extends into the exhaust duct 23. The first air guide plate 31 is inclined from top to bottom towards the direction of the incoming cooling airflow. By setting the air guiding structure to include a first air guide plate 31, the setting of the air guiding structure can be simplified, and the processing difficulty of the air guiding structure can be reduced. Specifically, the first air guide plate 31 extends from top to bottom towards the middle of the machine body. The angle between the first air guide plate 31 and the vertical direction is 30° to 60° to ensure the air guiding effect.

[0072] The air guiding structure also includes a second air guide plate 32. The first end of the second air guide plate 32 is connected to the lower end of the first air guide plate 31, and the second end of the second air guide plate 32 extends in the direction of incoming flow. The angle between the second air guide plate 32 and the horizontal plane is smaller than the angle between the first air guide plate 31 and the horizontal plane. By providing the second air guide plate 32, and ensuring that it extends in the direction of incoming flow, the air guiding effect on the cooling airflow can be further enhanced. Furthermore, the angle between the second air guide plate 32 and the horizontal direction is less than 10°. The second air guide plate 32 and the first air guide plate 31 are integrally formed.

[0073] Furthermore, the air guide plate assembly 3 also includes a third air guide plate 33, which extends vertically and its lower end is connected to the upper end of the first air guide plate 31. The third air guide plate 33 can further guide the cooling airflow upward, thereby enhancing the heat dissipation effect on the door lock drive motor 111.

[0074] In this embodiment, the air guide plate assembly 3 also includes a mounting shaft 34. The bottom of the mounting cavity 143 protrudes from opposite sides of the heat dissipation vent 1421 and is provided with mounting ears. The two ends of the mounting shaft 34 are respectively inserted into the mounting ears. The upper end of the first air guide plate 31 and the lower end of the third air guide plate 33 are both mounted on the mounting shaft 34. This simplifies the installation structure of the first air guide plate 31 and the third air guide plate 33 and ensures the convenience and stability of the air guide structure in the mounting cavity 143.

[0075] like Figures 6 to 8 As shown, the exhaust duct 23 includes a condensing duct 231 and a cooling duct 232 separated from each other. The front ends of both the condensing duct 231 and the cooling duct 232 are connected to the exhaust port 25. The inner cavity of the inner liner 30 is connected to the condensing duct 231, and the air outlet of the cooling fan 5 is connected to the cooling duct 232. The cooling airflow condenses and dissipates heat from the gas in the condensing duct 231. Specifically, the front end of the fan shroud 2 has a front panel 26, and the exhaust port 25 is disposed on the front panel 26.

[0076] Furthermore, a condensing device 4 is provided inside the hood 2. The condensing device 4 divides the exhaust air duct 23 into a heat dissipation air duct 232 and a condensing air duct 231. The condensing device 4 is used to condense and dissipate heat from the steam in the condensing air duct 231. The cooling airflow is used to dissipate heat from the condensing device 4. That is, the heat of the hot steam is first conducted to the condensing device 4 and then carried away by the cooling airflow flowing through the condensing device 4.

[0077] Specifically, the condensing device 4 includes a condensing plate 41 and a radiator 42 mounted on the condensing plate 41. The condensing plate 41 is installed inside the fan shroud 2, dividing the inner cavity of the fan shroud 2 into a condensing air duct 231 and a cooling air duct 232. The condensing air duct 231 is located below the condensing plate 41, and the radiator 42 is located within the condensing air duct 231. An exhaust pipe 27 is provided on the fan shroud 2. One end of the exhaust pipe 27 is connected to the condensing air duct 231, and the other end of the exhaust pipe 27 extends outside the fan shroud 2 and is connected to the inner cavity of the inner liner 30. An air outlet 411 is provided at the front end of the condensing plate 41. The air outlet 411 is located in front of the radiator 42. The steam condensed and cooled by the radiator 42 enters the front end of the fan shroud 2 through the air outlet 411 and merges with the cooling airflow in the cooling air duct 232, and is discharged together from the exhaust port 25. That is, in this embodiment, the front end of the hood 2 is formed with an air outlet duct 233 for converging steam and cooling airflow, and the air outlet duct 233 is connected to the exhaust port 25.

[0078] The specific structure of the condenser 4 and its installation structure in the shroud 2 can be set with reference to the existing technology. This is not the focus of this invention and will not be described in detail here.

[0079] In this embodiment, the air guiding structure also includes an inner flow guiding structure 24, which guides part of the cooling airflow in the heat dissipation air duct 232 to the air inlet 221. This ensures that the airflow to the door lock drive assembly 11 is a steam-free airflow, thus preventing steam from affecting the operation of the door lock drive assembly 11. While achieving heat dissipation and cooling of the door lock drive assembly 11, the reliability and safety of the door lock drive assembly 11 are guaranteed.

[0080] Since the door lock drive assembly 11 is located near the front of the machine body, to further prevent steam discharged from the inner liner 30 from flowing to the air vent 221, in this embodiment, the air guiding structure includes an inner flow guiding structure 24 located inside the fan shroud 2. The inner flow guiding structure 24 surrounds and forms an air guiding duct 242, which is separated from the condensation duct 231. The rear end of the air guiding duct 242 is connected to the heat dissipation duct 232, and the air vent 221 is located inside the air guiding duct 242. Thus, by separating the air guiding duct 242 from the condensation duct 231, the airflow in the condensation duct 231 is prevented from flowing to the air vent 221, thereby further ensuring the safety and reliability of the door lock drive assembly 11.

[0081] Furthermore, the heat dissipation duct 232 includes a central duct 2321 located below the condensation duct 231 and side ducts 2322 located on the left and right sides of the condensation duct 231. The rear end of the air guide duct 242 is connected to one of the side ducts 2322. This arrangement improves the ease of connection between the air guide duct 242 and the heat dissipation duct 232 and simplifies the connection structure between them.

[0082] In this embodiment, the hood 2 includes a main hood body 21, with extended hood portions 22 extending outward in the left-right direction from both sides of the front end of the main hood body 21. The door lock drive assembly 11 is installed at the extended hood portions 22. This arrangement facilitates airflow and air guiding through the extended hood portions 22; simultaneously, the extended hood portions 22 ensure that the width of the front end of the hood 2 in the left-right direction is approximately consistent with the width of the panel support 81, facilitating the fit between the hood 2 and the panel support 81 and preventing gaps from forming between them.

[0083] Specifically, in this embodiment, the drive seat 14 is mounted on the upper side of the extension cover 22, and the front end of the drive seat 14 is supported on the panel bracket 81 and is detachably fastened to the panel bracket 81 by a front fastener. The rear end of the drive seat 14 extends downward to a support column, which is supported on the top support plate 62. The support column and the top support plate 62 are detachably connected by a rear fastener to ensure the installation stability and reliability of the drive seat 14, while reducing the number of openings on the surface of the wind cover 2.

[0084] In this embodiment, the internal airflow structure 24 includes two air guide ribs 241 arranged opposite to each other and spaced apart, which together form an airflow duct 242. The rear end of one air guide rib 241 extends into the side airflow duct 2322, and the rear end of the other air guide rib 241 extends into the side airflow duct 2322 or is connected to the airflow duct wall of the side airflow duct 2322; and / or, the front ends of both air guide ribs 241 extend to the front side wall of the hood 2. By setting the air guide ribs 241 to form the airflow duct 242, the structure is simple, easy to implement, and easy to process the hood 2.

[0085] Furthermore, in this embodiment, two air guide ribs 241 are formed by protruding downwards from the upper side of the shroud 2, and the lower side of the air guide ribs 241 abuts against the top support plate 62. The upper sidewall of the shroud 2, the top support plate 62, and the two air guide ribs 241 together form an enclosing air guide duct 242, simplifying the structure of the air guide duct 242. The air guide ribs 241 are integrally formed from the shroud 2. In other embodiments, the air guide ribs 241 can also be separately formed from the shroud 2.

[0086] For ease of description, one air guide rib 241 is referred to as the first rib 241a, and the other air guide rib 241 is referred to as the second rib 241b. The first rib 241a is located on the side of the second rib 241b away from the center line of the hood 2. The rear end of the first rib 241a is connected to the front end of the side wall of the side air duct 2322 away from the central air duct 2321, and the front end of the first rib 241a is connected to the front side wall of the hood 2. The rear end of the second rib 241b extends into the interior of the side air duct 2322, and the front end of the second rib 241b is connected to the front panel 26 of the hood 2.

[0087] To further enhance the airflow guiding effect, the airflow duct 242 is at least partially formed with a narrowed airflow duct section 2421, the width of which gradually decreases along the direction towards the air intake 221. This narrowed airflow duct section 2421 increases the velocity of the cooling airflow flowing from the side airflow duct 2322 to the air intake 221, and also increases the air volume of the cooling airflow towards the air intake 221, thereby improving the airflow effect.

[0088] In this embodiment, the first rib 241a includes a first rib portion, a second rib portion, and a third rib portion connected in sequence. The first and third rib portions extend from back to front, the second rib portion extends in a left-right direction, and the front end of the third rib portion is connected to the front sidewall of the hood 2. The third rib portion, the second rib portion, and the front sidewall of the hood 2 form a transverse channel portion 2422. A narrowed air duct portion 2421 is located upstream of the transverse channel portion 2422, and an air inlet 221 is located downstream of the transverse channel portion 2422. The narrowed air duct portion 2421 is formed between the front portions of the first rib portion and the second rib 241b. Further, the front end of the second rib 241b has a guide rib portion 241b1, which extends from the front end to the rear in a direction toward the longitudinal center of the hood 2. The narrowed air duct portion 2421 is formed between the guide rib portion 241b1 and the first rib portion.

[0089] To further reduce the impact of steam on the door lock drive assembly 11, a dehumidification device 7 is installed inside the fan shroud 2. The dehumidification device 7 is located inside the air duct 242 and on the flow path of the cooling airflow towards the air inlet 221. This allows the dehumidification device 7 to dry the airflow towards the air inlet 221, ensuring that the airflow towards the door lock drive assembly 11 is dry.

[0090] In this embodiment, the dehumidification device 7 includes a semiconductor refrigeration device, and a humidity detection element is installed in the air duct 242. The humidity detection element is located downstream of the semiconductor refrigeration device, and both the semiconductor refrigeration device and the humidity detection element are communicatively connected to the main control board 20. This arrangement allows the humidity value detected by the humidity detection element to determine whether dehumidification of the cooling airflow is necessary, thereby avoiding the dehumidification device 7 from running continuously, ensuring the dehumidification effect while also reducing the cost of the cooking equipment.

[0091] To better ensure the dehumidification effect of the dehumidification device 7 on the airflow, a dividing rib 243 is provided inside the air duct 242. The two ends of the dividing rib 243 extend to the opposite sides of the air duct wall of the air duct 242, dividing the air duct 242 into an upstream air duct and a downstream air duct. A connecting opening is provided on the dividing rib 243, connecting the upstream and downstream air ducts. The dehumidification device 7 is installed at the connecting opening. This arrangement ensures that all cooling airflow from the upstream air duct to the downstream air duct passes through the dehumidification device 7, thereby ensuring the dehumidification effect of the dehumidification device 7 on the cooling airflow. Preferably, the dehumidification device 7 is directly opposite the air inlet of the constricted air duct section 2421.

[0092] A motherboard heat dissipation vent 211 is provided on the upper side of the fan cover 2, and the motherboard heat dissipation vent 211 is located inside the air guide duct 242. As a result, part of the cooling airflow entering the air guide duct 242 from the side air duct 2322 flows upward through the motherboard heat dissipation vent 211 to the main control board 20, thereby dissipating heat from the main control board 20 and ensuring the operational reliability of the electrical components on the main control board 20.

The cooking device provided in this embodiment has the same basic structure as the cooking device provided in Embodiment 1, with only some differences in settings. This embodiment will not elaborate on the structure that is the same as that in Embodiment 1.

[0095] In this embodiment, the drive seat 14 is installed above the fan cover 2, and the bottom of the mounting cavity 143 is provided with a heat dissipation vent 1421. The upper side of the fan cover 2 is provided with a corresponding air intake vent 221. The heat dissipation vent 1421 and the air intake vent 221 are directly connected and aligned vertically.

[0096] The air guiding structure includes an air guide plate, and the cooking equipment includes an air guiding drive component. The air guiding drive component drives the air guide plate to switch between an air guiding position and a closed position. When the air guide plate is in the air guiding position, the air guide plate passes through the heat dissipation vent 1421 and the air intake vent 221, and guides the cooling airflow to enter the installation cavity 143 in sequence through the air intake vent 221 and the heat dissipation vent 1421. When the air guide plate is in the closed position, the air guide plate closes the heat dissipation vent 1421 or the air intake vent 221.

[0097] A temperature sensor is installed in the cavity 143. The cooking equipment has a controller. The temperature sensor and the air guide drive are both connected to the controller. The controller controls the operation of the air guide drive based on the temperature detected by the temperature sensor. And / or, a humidity sensor is installed in the exhaust duct 23. The humidity sensor is located near the air inlet 221. The humidity sensor is connected to the controller.
