[0035] Please combine Figures 1 to 5 As shown, the present application first provides a cleaning structure, including an inner tank 10 and a heat dissipation component 20, the heat dissipation component 20 includes an air guide plate 21 and a fan 22, the air guide plate 21 is fixed to the top of the inner tank 10 to form an exhaust cavity between the air guide plate 21 and the inner tank 10, the exhaust cavity is communicated with the inner tank 10 and the outside respectively, the fan 22 is fixed to the air guide plate 21, the cleaning structure also includes a spray component 30 and a clutch component 40, the spray component 30 includes a spray rotor 31, a spray arm 32 and a water inlet waterway 33, The spray rotor 31 passes through the top wall of the inner tank 10, the spray arm 32 is fixed to the bottom end of the spray rotor 31, and the water inlet channel 33 is connected to the top of the spray rotor 31; the clutch assembly 40 includes a fan gear 41, a spray gear 42 and a clutch gear 43, the fan gear 41 is relatively fixed to the output shaft of the fan 22, the spray gear 42 is located at the top of the inner tank 10 and is fixed to the spray rotor 31, and the clutch gear 43 is movably arranged at the top of the inner tank 10 to connect or disconnect the fan gear 41 and the spray gear 42.

[0036] In the present application, by setting up a clutch assembly 40, the fan 22 used for heat dissipation and exhaust can be used as a power source, so that it has a transmission relationship with the spray assembly 30, and different functional requirements (conventional steaming and baking or spray cleaning) can be met by controlling the engagement or disengagement of the clutch gear 43. Since there is no need to add an additional power source such as a power pump, the present application effectively reduces the equipment size and equipment cost while realizing the spray cleaning function.

[0037] Specifically, during the conventional steaming and baking process, the clutch gear 43 is disengaged, the fan gear 41 is disconnected from the spray gear 42, and the fan 22 is started to discharge the water vapor in the inner pot 10 along the exhaust cavity, thereby achieving the effect of exhaust and heat dissipation;

[0038] During spray cleaning, the fan gear 41 and the spray gear 42 are meshed through the clutch gear 43. At this time, the fan 22 starts to drive the spray arm 32 to rotate, serving as the power source for the rotation of the spray arm 32. In conjunction with the original water inlet waterway 33 of the steam function to provide water source, spray cleaning can be achieved.

[0039] In some embodiments, the fan gear 41 is fixed to the outer peripheral surface of the impeller of the fan 22 , and the spray gear 42 is fixed to the outer peripheral surface of the spray rotor 31 .

[0040] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the clutch assembly 40 further includes a slide rail 44 and a slide rod 45. The slide rail 44 is disposed at the top of the inner container 10. The clutch gear 43 is rotatably connected to the slide rod 45. The slide rod 45 is slidably connected to the slide rail 44, so that the clutch gear 43 has two states of engagement and disconnection.

[0041] In the meshing state, the clutch gear 43 is meshing with the fan gear 41 and the spray gear 42. The fan 22 drives its own impeller to rotate, and also drives the spray gear 42 to rotate through the clutch gear 43, thereby driving the spray arm 32 to rotate, and spraying and cleaning various positions inside the inner tank 10;

[0042] In the disconnected state, the clutch gear 43 is disconnected from at least one of the fan gear 41 and the spray gear 42. At this time, the rotation of the fan 22 only drives its own impeller to rotate, thereby achieving normal heat dissipation and exhaust function.

[0043] Preferably, in the disconnected state, the clutch gear 43 is disconnected from the fan gear 41 and the spray gear 42 .

[0044] Of course, in some other embodiments, the clutch gear 43 may also be other movable structures, such as moving along its own axial direction, etc. The present application does not give examples one by one here, as long as the engagement and disconnection between the fan gear 41 and the spray gear 42 can be achieved through the movement of the clutch gear 43.

[0045] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the cleaning structure also includes a trigger assembly 50, which is power-connected to the slide rod 45 to drive the slide rod 45 to reciprocate along the length direction of the slide rail 44; the slide rail 44 can limit the moving direction of the slide rod 45 to ensure the stability of the clutch gear 43 switching between the two states.

[0046] Specifically, the trigger assembly 50 can be electrically controlled by setting a motor, a pneumatic push rod, etc., or it can be manually operated by the user by setting a physical button. As long as the slide bar 45 can be controlled to move along the length direction of the slide rail 44 as needed, the present application will not give examples one by one here.

[0047] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the trigger assembly 50 includes a baking tray 51, a button 52 and a trigger push rod 53. The button 52 is arranged on the inner wall of the inner pot 10. A trigger baking tray rack 11 corresponding to the button 52 is arranged inside the inner pot 10. The baking tray 51 is detachably arranged on the trigger baking tray rack 11 and abuts against the button 52. One end of the trigger push rod 53 is fixed to the button 52, and the other end is dynamically connected to the slide rod 45.

[0048] When spray cleaning is required, the baking tray 51 is placed on the trigger baking tray rack 11, and the baking tray 51 presses the trigger button 52, and the button 52 drives the trigger push rod 53 to move backward together, thereby driving the clutch gear 43 to move to a meshing state through the sliding rod 45;

[0049] When conventional steaming and baking is required, the baking tray 51 is taken out from the trigger baking tray rack 11, the button 52 is reset and drives the trigger push rod 53 and the slide rod 45 to move together, thereby driving the clutch gear 43 to move to the disconnected state.

[0050] In some embodiments, multiple conventional baking tray racks are also provided inside the inner pot 10, and the trigger baking tray rack 11 is located at the bottom relative to other conventional baking tray racks. When spray cleaning is performed, the baking tray 51 is placed on the trigger baking tray rack 11 to obtain a larger accommodating space, and items that need to be cleaned, such as dishes and chopsticks, can be placed on the baking tray 51 and washed together.

[0051] Of course, in some other embodiments, the button 52 may also be set at other positions, such as the operation panel position on the front of the device, as long as the button 52 is connected to the slide bar 45 through the trigger push rod 53.

[0052] Please combine Figure 2 , Figure 4 as well as Figure 6As shown, in some embodiments, a rack 53a is fixed to the end of the trigger push rod 53, and the clutch assembly 40 also includes a rack slide rail 46, a transmission gear 47, a transmission rod 48 and a sliding pin 49. The rack slide rail 46 and the transmission gear 47 are both arranged on the top of the inner liner 10, the rack 53a is slidably connected to the rack slide rail 46, and the rack 53a is also meshed with the transmission gear 47, the transmission rod 48 is rotatably connected to the transmission gear 47, and the transmission rod 48 is provided with a limiting groove 48a along its own length direction, and the sliding pin 49 is fixed to the slide rod 45 and is slidably connected to the inner wall of the limiting groove 48a.

[0053] When the trigger push rod 53 moves, it drives the rack 53a along the length direction of the rack slide rail 46, thereby driving the transmission gear 47 to rotate. The transmission gear 47, the transmission rod 48, the slide rail 44 and the slide rod 45 form a crank connecting rod structure. The rotation of the transmission gear 47 can drive the slide rod 45 to move back and forth.

[0054] Of course, in some other embodiments, other commonly used transmission structures may also be used between the trigger push rod 53 and the slide rod 45, as long as a power connection can be formed between the two. This application does not give examples one by one here.

[0055] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the button 52 includes a button rod 52a and a spring 52b. The button rod 52a passes through the inner liner 10. One end of the button rod 52a located in the inner liner 10 is fixed with a button plate 52c, and the other end is fixed to the trigger push rod 53. The two ends of the spring 52b are respectively against the button plate 52c and the inner wall of the inner liner 10.

[0056] Spring 52b is a compression spring. When spray cleaning is required, the baking tray 51 is inserted into the trigger baking tray rack 11, and the baking tray 51 overcomes the elastic force of the spring 52b to squeeze the button 52; conversely, when conventional steaming and baking is required, the baking tray 51 is pulled out from the trigger baking tray rack 11, and the button 52 rebounds and resets under the elastic force of the spring 52b.

[0057] Of course, the button 52 may also be reset by a built-in magnet or other structure, as long as the button 52 can be reset and popped out when the baking tray 51 is pulled out. This application will not give examples one by one here.

[0058] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the baking tray 51 and the corresponding side of the button 52 are rotatably connected with a trigger rod 51a.

[0059] Such a configuration can meet the requirement of placing the baking tray 51 on the trigger baking tray rack 11 during conventional steaming and baking. Only the trigger rod 51a needs to be rotated until it is away from the button 52, so that the baking tray 51 will not be squeezed and triggered when it is inserted into the trigger baking tray rack 11. Conversely, the trigger rod 51a can be rotated to correspond to the button 52, so that the button 52 can be triggered when the baking tray 51 is inserted into the trigger baking tray rack 11, thereby further improving the versatility of the equipment.

[0060] Please combine Figure 5 as well as Figure 7 As shown, in some embodiments, the water inlet water circuit 33 includes a water tank 33a, a water pump 33b, a three-way joint 33c, a first valve body 33d, a second valve body 33e and a heater 33f, wherein the water tank 33a, the water pump 33b, the three-way joint 33c, the first valve body 33d and the inner tank 10 are connected in sequence to form a first water circuit, and the water tank 33a, the water pump 33b, the three-way joint 33c, the second valve body 33e, the heater 33f and the spray rotor 31 are connected in sequence to form a second water circuit.

[0061] When the first valve body 33d is opened and the second valve body 33e is closed, the first water circuit is connected, and the water inlet circuit 33 can provide water for the steaming and baking function in the inner pot 10; and when the first valve body 33d is closed and the second valve body 33e is opened, the second water circuit is connected, and the water inlet circuit 33 can provide cleaning water for the spray rotor 31 and the spray arm 32.

[0062] In addition, by increasing the temperature of the washing water through the heater 33f, the effect of the spray washing can be effectively improved.

[0063] Please refer to Figure 5 As shown, in some embodiments, the spray arm 32 includes a plurality of spray blades 32a that are circumferentially arranged at equal intervals with the spray rotor 31 as the center. The spray blades 32a are all arranged in the radial direction and connected to the spray rotor 31. Each spray blade 32a is provided with a water outlet hole 32b facing a different direction, so that the water can be sprayed in different directions after passing through the water outlet hole 32b, thereby achieving sufficient cleaning of the inside of the inner tank 10.

[0064] In some embodiments, the spray arm 32 is clamped to the spray rotor 31 via a clamping spring to facilitate installation and disassembly.

[0065] In some embodiments, the water inlet waterway 33 is connected to the spray rotor 31 through a water inlet joint. The water inlet joint is a sealing structure, and a sealed rolling bearing is provided between the water inlet joint and the spray rotor 31.

[0066] A second aspect of the present application provides a multifunctional cooking device, comprising the above-mentioned cleaning structure.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
