[0050] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0051] This embodiment provides a cooking device, which can realize automatic door opening and closing control of the cooking device, improve the safety and reliability of the cooking device, and enhance the performance of the cooking device. The cooking device is a cooking device with a steam cooking function, which can be but not limited to an electric steamer, a steam oven, etc.
[0052] like Figures 1 to 5 As shown, in this embodiment, the cooking device includes a machine body, a machine door 10 and a door lock device 1. The machine body includes a chassis 6, an inner pot 30 located inside the chassis 6, and a fan 2 and a heat dissipation fan 5 located on the top of the inner pot 30. The fan 2 has an exhaust air duct 23 connected to the inner cavity of the inner pot 30, and the heat dissipation fan 5 guides the external cooling air flow to the exhaust air duct 23; the machine door 10 is movably installed on the front side of the machine body and a lock component 9 is arranged on the top; the door lock device 1 includes a door lock drive component 11 and a door lock component 13 connected in a transmission manner. The door lock drive component 11 is arranged in the machine body, and the door lock component 13 partially extends out of the front side of the fan 2. The door lock drive component 11 drives the door lock component 13 to lock or unlock with the lock component 9.
[0053] That is, during the cooking process of the cooking device, the door lock assembly 13 and the lock component 9 cooperate to achieve the locking of the machine door 10 relative to the machine body, thereby preventing the steam in the inner pot 30 from leaking out; when the hot steam in the inner pot 30 needs to be discharged during the cooking process or after cooking, the hot steam is discharged into the exhaust duct 23 and discharged outwardly through the exhaust duct 23. At the same time, since the heat dissipation fan 5 guides the external cooling air flow into the exhaust duct 23, it can be beneficial to condense and cool the hot steam in the exhaust duct 23, thereby reducing the steam discharge temperature, thereby preventing the discharged hot steam from scalding the user.
[0054] In this embodiment, the cooking device further includes an air guiding structure, which at least partially extends into the exhaust air duct 23 to guide part of the cooling air flow in the exhaust air duct 23 to blow toward the door lock drive assembly 11.
[0055] The cooking device provided by the present invention guides the cooling airflow in the exhaust air duct 23 to the door lock drive assembly 11 by arranging an air guide structure, so that the cooling airflow can dissipate heat and cool down the door lock drive assembly 11, avoid heat accumulation at the door lock drive assembly 11, and improve the safety and reliability of the door lock drive assembly 11; at the same time, since the cooling airflow guided by the air guide structure is the cooling airflow formed by the original air hood 2 and the heat dissipation fan 5 of the cooking device, the original structure in the cooking device can be effectively used to dissipate heat and cool down the door lock drive assembly 11, thereby 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, in order to simplify the exhaust structure of the cooking device, an exhaust port 25 is formed on the front side of the hood 2, and the front end of the exhaust duct 23 is connected to the exhaust port 25. Specifically, the chassis 6 also includes a front frame arranged around 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 the front end, a door frame arranged around the outside of the front frame, and a housing 61 forming the outer shell of the machine body, and the hood 2 is installed above the top support plate 62. The machine body also includes a control panel 8, which is installed on the front side of the upper end of the door frame through a panel bracket 81, and the rear side of the lower end of the control panel 8 overlaps the rear side of the front end of the hood 2.
[0057] The control panel 8 extends forward from the front side of the inner pot 30. When the door 10 is closed, the top of the door 10 is spaced apart from the lower side of the control panel 8 and an exhaust gap is formed between the two. The exhaust port 25 is arranged opposite to the exhaust gap. Preferably, a plurality of exhaust ports 25 are spaced apart in the left-right direction. Further, the cooking device includes a main control panel 20, which is installed above the fan cover 2, and the control panel 8 and the door lock drive assembly 11 are both connected to the main control panel 20 for communication.
[0058] The door lock assembly 13 is installed in the middle position of the machine body along the left-right direction, and the lock component 9 is set in the middle position of the machine door 10 along the left-right direction, which is conducive to improving the force balance and stability of the machine door 10 when opening and closing the door. The door lock drive assembly 11 is preferably installed at one end of the machine body along the left-right direction to avoid the problem of more parts in the middle area of the top of the machine body due to the door lock drive assembly 11 being installed in the middle, which is easy to cause interference, and improve the rationality of the structural layout in 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 unlocking position and the locking position through the transmission assembly 12. The transmission assembly 12 extends in the left-right direction.
[0059] In this embodiment, the door lock device 1 includes a lock seat 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 can be rotatably installed on the lock seat 15 around its own axis and the lower end passes through the panel bracket 81 downward, so that the door hook is located at the front side of the wind hood 2 and below the control panel 8, so as to facilitate 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 the door hook is located in the top cavity and is rotatably installed on the lock seat 15, and the front end of the door hook passes through the lower side of the panel bracket 81 to be located at the front side of the wind 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 repeated here.
[0060] The door lock device 1 includes a drive seat 14, which is installed inside the body, and the door lock drive assembly 11 is installed on the drive seat 14. The drive seat 14 and the lock seat 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 assembly 12 connected between the door lock drive assembly 11 and the door lock assembly 13. The door lock drive assembly 11 drives the transmission assembly 12 to move in the left and right directions to push the door lock assembly 13 to rotate around an axis to achieve the switching of the door lock assembly 13 from a locked position to an unlocked position.
[0062] In this embodiment, the door lock drive assembly 11 includes a door lock drive assembly 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, and 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 and right directions toward the door lock assembly 13, thereby driving the connecting rod 122 to move, so as to 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 member, 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 above-mentioned transmission assembly 12 and door lock drive assembly 11 are only exemplary structures. Any structure in the prior art that can realize the door lock drive assembly 11 driving the transmission assembly 12 to activate the door lock assembly 13 to rotate can be applied to the present invention. This is not the focus of improvement of the present invention and will not be repeated here.
[0064] Furthermore, the panel bracket 81 includes a bracket front plate 812 arranged vertically, a bracket bottom plate 811 connected to the lower side of the bracket front plate 812, a bracket top plate connected to the upper side of the bracket front plate 812, and bracket side plates connected to the left and right sides of the bracket front plate 812, and the bracket side plates are connected to the door frame. In this embodiment, the rear end of the bracket bottom plate 811 is laid on the upper side of the front end of the wind hood 2, the lock seat 15 is installed on the bracket bottom plate 811, and the lock shaft passes through the bracket bottom plate 811 downward.
[0065] In order to further improve the wind-guiding and heat-dissipating effect of the door lock drive assembly 11, the drive seat 14 has a mounting cavity 143, and the door lock drive assembly 11 is at least partially located in the mounting cavity 143, and the wind-guiding structure guides the cooling airflow to blow toward the mounting cavity 143. By providing the mounting cavity 143 in the drive seat 14, and allowing the wind-guiding structure to guide the cooling airflow to blow toward the mounting cavity 143, the cooling airflow flowing out of the wind cover 2 can be concentrated to prevent the cooling airflow flowing out of the wind cover 2 from flowing to other positions.
[0066] Furthermore, a detection sensor 40 is also disposed in the installation cavity 143 , and the detection sensor 40 is used to detect the operating status of the door lock drive assembly 11 to better meet the control requirements of the door lock device 1 .
[0067] The drive seat 14 is installed above the hood 2, and a heat dissipation vent 1421 is provided at the bottom of the installation cavity 143. The heat dissipation vent 1421 is directly connected to the air inlet 221, and the upper side of the hood 2 is correspondingly provided with an air inlet 221. The air guide structure is at least partially provided through the heat dissipation vent 1421 and the air inlet 221, and guides the cooling air flow to sequentially pass through the air inlet 221 and the heat dissipation vent 1421 and enter the installation cavity 143. By partially providing the air guide structure through the heat dissipation vent 1421 and the air inlet 221, the cooling air flow in the exhaust air duct 23 can be better guided to flow into the installation cavity 143, thereby improving the guiding effect of the air guide structure on the cooling air flow, and further improving the cooling effect of the cooling air flow on the door lock drive assembly 11.
[0068] In order to improve the installation convenience of the door lock drive assembly 11, the drive seat 14 includes a base 142 and an upper cover 141. The base 142 has an open groove, and the upper cover 141 is set at the notch of the groove. The upper cover 141 and the base 142 are surrounded to form an installation cavity 143. The upper cover 141 is detachably connected to the base 142, so that the internal structure of the installation cavity 143 can be disassembled and assembled by disassembling the upper cover 141 relative to the base 142. The base 142 is detachably mounted on the body.
[0069] Furthermore, a vent 1411 is provided on the upper side of the drive seat 14, and the door lock drive assembly 11 includes a door lock drive motor 111. The door lock drive motor 111 is installed on the outer side of the drive seat 14, and the output shaft of the door lock drive motor 111 extends into the installation cavity 143 through the vent 1411, and the heat dissipation vent 1421 is arranged vertically opposite to the vent 1411. The transmission assembly 12 is partially located in the installation cavity 143 to cooperate with the motor shaft of the door lock drive motor 111. By installing the door lock drive motor 111 on the outer side of the drive seat 14, the space requirement for the installation cavity 143 can be reduced, and the heat dissipation of the door lock drive motor 111 can be more convenient; at the same time, by providing the vent 1411 on the upper cover 141, the cooling air flow flowing into the installation cavity 143 can flow upward through the vent 1411, thereby dissipating the heat of the main structure of the door lock drive motor 111.
[0070] To ensure the heat dissipation effect, the aperture of the vent 1411 is at least four times larger than the diameter of the output shaft, so that there is a sufficient path for cooling air flow between the side wall of the vent 1411 and the output shaft, thereby ensuring the cooling effect on the door lock drive motor 111.
[0071] Furthermore, the wind guide structure includes a wind guide plate assembly 3, and the wind guide plate assembly 3 includes a first wind guide plate 31. The first wind guide plate 31 is inserted into the heat dissipation outlet 1421 and the air inlet 221. The upper end of the first wind guide plate 31 is located in the installation cavity 143 and the lower end extends into the exhaust air duct 23. The first wind guide plate 31 is inclined from top to bottom toward the incoming flow direction of the cooling airflow. By setting the wind guide structure to include the first wind guide plate 31, the setting of the wind guide structure can be simplified and the processing difficulty of the wind guide structure can be reduced. Specifically, the first wind guide plate 31 extends from top to bottom toward the middle of the body. The angle of the first wind guide plate 31 relative to the vertical direction is 30° to 60°, so as to ensure the wind guiding effect.
[0072] The wind guide structure also includes a second wind guide plate 32, a first end of the second wind guide plate 32 is connected to the lower end of the first wind guide plate 31, a second end of the second wind guide plate 32 extends in the direction of the incoming flow, and an angle between the second wind guide plate 32 and the horizontal plane is smaller than an angle between the first wind guide plate 31 and the horizontal plane. By providing the second wind guide plate 32 and extending in the direction of the incoming flow, the wind guiding and drainage effect on the cooling airflow can be further enhanced. Furthermore, the angle between the second wind guide plate 32 and the horizontal direction is less than 10°. The second wind guide plate 32 is integrally formed with the first wind guide plate 31.
[0073] Furthermore, the air guide plate assembly 3 also includes a third air guide plate 33, which extends vertically and has a lower end connected to an upper end of the first air guide plate 31. The third air guide plate 33 can further guide the cooling airflow to flow 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, and the bottom of the mounting cavity 143 is provided with mounting ears protruding on opposite sides of the heat dissipation outlet 1421, and the two ends of the mounting shaft 34 are respectively passed through the mounting ears, and the upper end of the first air guide plate 31 and the lower end of the third air guide plate 33 are both installed on the mounting shaft 34, thereby simplifying the installation structure of the first air guide plate 31 and the third air guide plate 33, and ensuring the installation convenience and installation stability of the air guide structure in the mounting cavity 143.
[0075] like Figures 6 to 8 As shown, the exhaust air duct 23 includes a condensation air duct 231 and a heat dissipation air duct 232 which are separated and arranged. The front ends of the condensation air duct 231 and the heat dissipation air duct 232 are both connected to the exhaust port 25. The inner cavity of the inner tank 30 is connected to the condensation air duct 231. The air outlet of the heat dissipation fan 5 is connected to the heat dissipation air duct 232.

Specifically, the front end of the hood 2 has a front panel 26, and the exhaust port 25 is arranged on the front panel 26.
[0076] Furthermore, a condensing device 4 is provided inside the wind hood 2, and the condensing device 4 divides the exhaust air duct 23 into a heat dissipation air duct 232 and a condensation air duct 231. The condensing device 4 is used to condense and dissipate the steam in the condensation air duct 231, and the cooling air flow is used to dissipate the heat of 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 air flow flowing through the condensing device 4.
[0077] Specifically, the condensing device 4 includes a condensing plate 41 and a radiator 42 disposed on the condensing plate 41. The condensing plate 41 is installed inside the hood 2 and divides the inner cavity of the hood 2 into a condensing air duct 231 and a heat dissipation air duct 232, wherein the condensing air duct 231 is located at the lower side of the condensing plate 41, and the radiator 42 is located in the condensing air duct 231. An exhaust pipe 27 is disposed on the hood 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 out of the hood 2 and is connected to the inner cavity of the liner 30. An air outlet 411 is disposed at the front end of the condensing plate 41, and 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 hood 2 through the air outlet 411 and merges with the cooling air flow in the heat dissipation air duct 232, and is discharged from the exhaust port 25 together. That is, in this embodiment, an air outlet duct 233 for merging steam and cooling airflow is formed at the front end of the air hood 2 , and the air outlet duct 233 is communicated with the exhaust port 25 .
[0078] The specific structure of the condensing device 4 and its installation structure in the wind cover 2 can be set with reference to the prior art. This is not the focus of the present invention and will not be described in detail here.
[0079] In this embodiment, the air guide structure also includes an internal drainage structure 24, which guides part of the cooling air in the heat dissipation duct 232 to the air inlet 221, thereby making the airflow flowing to the door lock drive assembly 11 a steam-free airflow, thereby avoiding the influence of steam on the operation of the door lock drive assembly 11. While achieving heat dissipation and cooling of the door lock drive assembly 11, the operating reliability and safety of the door lock drive assembly 11 are guaranteed.
[0080] Since the door lock drive assembly 11 is arranged close to the front side of the machine body, in order to further prevent the steam discharged from the inner tank 30 from flowing to the air inlet 221, in this embodiment, the air guide structure includes an inner guide structure 24 located in the wind cover 2, and the inner guide structure 24 is surrounded by an air guide duct 242, the air guide duct 242 is separated from the condensation duct 231, and the rear end of the air guide duct 242 is connected to the heat dissipation duct 232, and the air inlet 221 is located in the air guide duct 242. Therefore, by separating the air guide duct 242 from the condensation duct 231, the air flow in the condensation duct 231 can be prevented from flowing to the air inlet 221, thereby further ensuring the safety and reliability of the use of the door lock drive assembly 11.
[0081] Furthermore, the heat dissipation duct 232 includes a middle duct 2321 located at the lower side of the condensation duct 231 and side ducts 2322 located at the left and right sides of the condensation duct 231, and the rear end of the air guide duct 242 is connected to the side duct 2322. This arrangement can improve the convenience of connection between the air guide duct 242 and the heat dissipation duct 232 and simplify the connection structure between the air guide duct 242 and the heat dissipation duct 232.
[0082] In this embodiment, the air hood 2 includes a main hood body 21, and the front ends of the main hood body 21 are provided with extension hood parts 22 extending outwardly in the left and right directions. The door lock drive assembly 11 is installed at the extension hood part 22. This arrangement is conducive to achieving the wind induction and flow diversion effects through the extension hood part 22; at the same time, the arrangement of the extension hood part 22 enables the width of the front end of the air hood 2 in the left and right directions to be roughly consistent with the width of the panel bracket 81, which is conducive to the coordination between the air hood 2 and the panel bracket 81, and avoids the formation of a gap between the air hood 2 and the panel bracket 81.
[0083] Specifically, in the present embodiment, the drive seat 14 is straddled on the upper side of the extension cover portion 22, and the front end of the drive seat 14 is supported on the panel bracket 81 and detachably fastened to the panel bracket 81 by a front fastener, and a support column portion is extended downwardly from the rear end of the drive seat 14, and the support column portion is supported on the top support plate 62, and the support column portion 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 being able to reduce the number of openings on the surface of the wind cover 2.
[0084] In this embodiment, the internal air guide structure 24 includes two air guide ribs 241 that are opposite and spaced apart, and the two air guide ribs 241 enclose an air guide duct 242; the rear end of one air guide rib 241 extends into the side duct 2322, and the rear end of the other air guide rib 241 extends into the side duct 2322 or is connected to the duct wall of the side duct 2322; and / or, the front ends of the two air guide ribs 241 both extend to the front side wall of the hood 2. The structure of enclosing the air guide duct 242 by arranging the air guide ribs 241 is simple in structure, easy to implement, and easy to implement the processing of the hood 2.
[0085] Further, in this embodiment, two wind guide ribs 241 are formed by the upper side of the wind cover 2 protruding downward, and the lower side of the wind guide rib 241 is in contact with the top support plate 62, so that the upper side wall of the wind cover 2, the top support plate 62 and the two wind guide ribs 241 are formed to enclose the wind guide duct 242, simplifying the structure of the wind guide duct 242. The wind guide rib 241 is integrally formed with the wind cover 2. In other embodiments, the wind guide rib 241 can also be separately provided from the wind cover 2.
[0086] For convenience of description, one wind guide rib 241 is called the first rib 241a, and the other wind guide rib 241 is called 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 a side wall of the side duct 2322 away from the middle 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 to the inside of the side duct 2322, and the front end of the second rib 241b is connected to the front panel 26 of the hood 2.
[0087] In order to further improve the air guiding effect, the air guiding duct 242 at least partially forms a constricted duct portion 2421, and the duct width of the constricted duct portion 2421 gradually decreases in the direction toward the air inlet 221. Thus, the setting of the constricted duct portion 2421 can increase the flow rate of the cooling airflow flowing from the side duct 2322 to the air inlet 221, and is conducive to increasing the air volume of the cooling airflow flowing to the air inlet 221, thereby improving the flow effect of the airflow.
[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 rib portion and the third rib portion both extend from the back to the front, the second rib portion extends in the left-right direction, the front end of the third rib portion is connected to the front side wall of the hood 2, the third rib portion, the second rib portion, and the front side wall of the hood 2 are surrounded to form a transverse channel portion 2422, the constricted air duct portion 2421 is located upstream of the transverse channel portion 2422, the air inlet 221 is arranged downstream of the transverse channel portion 2422, and the constricted air duct portion 2421 is formed between the first rib portion and the front portion of the second rib 241b. Further, the front end of the second rib 241b has an air guide rib portion 241b1, the air guide rib portion 241b1 extends from the front end to the back in the direction toward the longitudinal center of the hood 2, and the constricted air duct portion 2421 is formed between the air guide rib portion 241b1 and the first rib portion.
[0089] In order to further reduce the impact of steam on the door lock drive assembly 11, a dehumidification device 7 is provided inside the air hood 2. The dehumidification device 7 is located in the air guide duct 242 and on the flow path of the cooling air flow to the air inlet 221. Thus, the air flow to the air inlet 221 can be dried and dehumidified by the dehumidification device 7, ensuring that the air flowing to the door lock drive assembly 11 is dry air.
[0090] In this embodiment, the dehumidification device 7 includes a semiconductor refrigeration device, a humidity detection component is provided in the air guide duct 242, the humidity detection component is located downstream of the semiconductor refrigeration device, and both the semiconductor refrigeration device and the humidity detection component are communicatively connected to the main control board 20. This arrangement can determine whether the cooling airflow needs to be dehumidified by the humidity value detected by the humidity detection component, thereby avoiding the dehumidification device 7 from always running, ensuring the dehumidification effect while also reducing the cost of the cooking equipment.
[0091] In order to better ensure the dehumidification effect of the dehumidification device 7 on the airflow, a separation rib 243 is provided in the air guide duct 242, and the two ends of the separation rib 243 extend to the opposite side duct walls of the air guide duct 242 respectively. The separation rib 243 separates the air guide duct 242 into an upstream duct and a downstream duct. A connecting port is provided on the separation rib 243, and the connecting port connects the upstream duct and the downstream duct. The dehumidification device 7 is installed at the connecting port.

Preferably, the dehumidification device 7 is directly opposite to the air inlet of the constricted duct portion 2421.
[0092] The upper side of the fan cover 2 is provided with a mainboard heat dissipation port 211, which is located in the air guide duct 242. Therefore, part of the cooling airflow entering the air guide duct 242 from the side duct 2322 flows upward to the main control board 20 through the mainboard heat dissipation port 211, thereby dissipating the heat of the main control board 20 and ensuring the operating reliability of the electrical components on the main control board 20.
