Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and in particular to an integrated fan blade system and cooking equipment. Background Technology

[0002] Cooking equipment refers to various devices used in the kitchen for processing, preparing and cooking food. Cooking equipment includes ovens, steam ovens, integrated stoves, stove-steam-grill combination machines, steam-grill combination machines, microwave-steam combination machines, microwave-grill combination machines, steam-grill-fry combination machines, or microwave-steam-grill combination machines. Different types of cooking equipment can meet the needs of different scenarios. A microwave-steam-grill combination machine is a kitchen appliance that integrates microwave, steam and baking functions. A microwave-steam-grill combination machine can perform multiple cooking methods such as steam cooking and baking.

[0003] Cooking equipment using related technologies, such as microwave-steam-grill combos, includes an inner cavity, cooling fan blades, and heating fan blades. Since microwave-steam-grill combos generate a lot of heat during operation, the cooling fan blades are mainly responsible for heat dissipation during operation, helping the heat inside the machine to dissipate quickly and protecting the machine's electronic components and internal structure. During baking, the heating fan blades rotate and agitate to create diffused convection hot air inside the inner cavity, allowing the heat to evenly cover the inside of the inner cavity, thereby improving heating efficiency.

[0004] However, the cooling fan blades and the heating fan blades require two separate motors to drive their rotation, and this setup takes up a significant amount of installation space. Summary of the Invention

[0005] This application provides an integrated fan blade system and cooking device to solve the technical problem that the heat dissipation fan blade and the heating fan blade of the related technology need to be driven by two independent motors, thus occupying a large installation space.

[0006] In a first aspect, embodiments of this application provide an integrated fan blade system, including:

[0007] A driving device is provided for driving one of the heat dissipation fan blades and the heating fan blades of the cooking equipment to rotate in the forward or reverse direction. The heat dissipation fan blades are used to blow the heat generated inside the cooking equipment to the outside of the cooking equipment, and the heating fan blades are used to form diffused convection hot air inside the inner pot of the cooking equipment.

[0008] A speed-changing device is provided, which is used to be disposed between the cooling fan blade and the heating fan blade to link the cooling fan blade and the heating fan blade. The speed-changing device is used to adjust the speed ratio between the cooling fan blade and the heating fan blade before and after the switching when one of the cooling fan blade and the heating fan blade switches between forward and reverse rotation.

[0009] In some embodiments, the speed change device includes:

[0010] An active mechanism is provided on one of the cooling fan blades and the heating fan blades, and rotates synchronously with one of the cooling fan blades and the heating fan blades;

[0011] A driven mechanism is provided on the other of the cooling fan blades and the heating fan blades, and drives the other of the cooling fan blades and the heating fan blades to rotate;

[0012] A switching mechanism is connected between the driving mechanism and the driven mechanism. When the driving mechanism switches between forward and reverse rotation, the switching mechanism adjusts the speed ratio of the driven mechanism before and after the switch.

[0013] In some embodiments, the switching mechanism includes:

[0014] A ratchet assembly is disposed between the driving mechanism and the driven mechanism. When the driving mechanism rotates in the forward direction, the ratchet assembly drives the driven mechanism to rotate. When the driving mechanism rotates in the reverse direction, the ratchet assembly stops driving the driven mechanism to rotate.

[0015] A gear reduction assembly is disposed between the driving mechanism and the ratchet assembly. When the driving mechanism rotates in the reverse direction, the gear reduction assembly drives the driven mechanism to rotate and adjusts the speed ratio of the driven mechanism before and after the switch.

[0016] In some embodiments, the ratchet assembly includes:

[0017] The first pawl is rotatably mounted on the active mechanism;

[0018] A ratchet is connected to the driven mechanism. When the driving mechanism rotates in the forward direction, the first pawl engages with the ratchet so that the ratchet drives the driven mechanism to rotate. When the driving mechanism rotates in the reverse direction, the first pawl disengages from the ratchet so that the ratchet drives the first pawl to rotate multiple times at the hinge point on the driving mechanism, thereby stopping the driving mechanism from rotating.

[0019] In some embodiments, the gear reduction assembly includes:

[0020] A center wheel is mounted on the ratchet to rotate synchronously with the ratchet.

[0021] The traveling wheel meshes with the central wheel;

[0022] A speed reduction component is disposed on the traveling wheel;

[0023] When the active mechanism rotates in the forward direction, the ratchet drives the center wheel to rotate in the forward direction, and the reducer drives the walking wheel to move circumferentially along the axis of the driven mechanism, so as to drive the driven mechanism to rotate in the forward direction. When the active mechanism rotates in the reverse direction, the reducer drives the walking wheel to rotate in the same position in the reverse direction, so that the walking wheel drives the center wheel to rotate in the forward direction, thereby causing the driven mechanism to rotate in the forward direction.

[0024] In some embodiments, the speed reducer includes a gear ring and a locking part. The gear ring is disposed on the driving mechanism, and the locking part is disposed between the driven mechanism and the traveling wheel. The locking part is used to restrict or disengage the traveling wheel from rotating in the same position. The traveling wheel engages between the center wheel and the gear ring.

[0025] When the active mechanism rotates in the forward direction, the locking part disengages from restricting the traveling wheel, the ratchet drives the center wheel to rotate in the forward direction, and the active mechanism drives the gear ring to rotate in the forward direction, so that the traveling wheel moves circumferentially along the axis of the driven mechanism; when the active mechanism rotates in the reverse direction, the locking part restricts the traveling wheel, so that the gear ring drives the traveling wheel to rotate in the reverse direction at the same position, so that the traveling wheel drives the center wheel to rotate in the forward direction.

[0026] In some embodiments, the locking portion includes:

[0027] The second pawl is rotatably mounted on the mounting bracket of the driven mechanism;

[0028] A locking rod is sleeved on and rotatably mounted on the driven mechanism, and a limiting rod is provided on the traveling wheel and rotatably mounted on the locking rod;

[0029] When the active mechanism rotates in the forward direction, the gear ring rotates in the forward direction, and the traveling wheel moves circumferentially along the axis of the driven mechanism. The traveling wheel drives the limiting rod to move circumferentially along the axis of the driven mechanism, and the limiting rod drives the locking rod to rotate in the forward direction, so that the locking rod abuts against the second pawl multiple times, and drives the second pawl to rotate at the hinge on the mounting bracket to disengage from restricting the traveling wheel. When the active mechanism rotates in the reverse direction, the gear ring rotates in the reverse direction, and the limiting rod drives the locking rod to engage with the second pawl to prevent the limiting rod from moving circumferentially along the axis of the driven mechanism, so that the traveling wheel drives the limiting rod to rotate in the reverse direction on the locking rod, thereby driving the traveling wheel to rotate in the same position in the opposite direction.

[0030] In some embodiments, the active mechanism is provided with a receiving port, the first pawl is hinged to the inner wall of the receiving port, and the ratchet is rotatably disposed inside the receiving port.

[0031] In some embodiments, the driving device is used to drive the cooling fan blades to rotate in the forward or reverse direction. When the cooling fan blades rotate, the speed change device drives the heating fan blades to rotate and switches the speed ratio between the cooling fan blades and the heating fan blades.

[0032] In some embodiments, the system includes an inner liner and a fan blade system integrated on the inner liner.

[0033] Secondly, embodiments of this application provide a cooking device, including an inner pot and an integrated fan blade system disposed on the inner pot.

[0034] In some embodiments, it also includes:

[0035] A duct structure is provided on the inner liner, and the duct structure is provided with an air inlet and an air outlet.

[0036] Cooling fan blades, wherein the cooling fan blades are disposed inside the air duct structure;

[0037] Heated fan blades, wherein the heated fan blades are disposed inside the inner liner;

[0038] The drive device is located outside the air duct structure, and the speed change device is located inside or outside the air duct structure.

[0039] The integrated fan blade system provided in this application employs a drive unit and a speed-changing device. When cooking, the drive unit rotates one of the cooling and heating fan blades in either the forward or reverse direction. The speed-changing device, in conjunction with the cooling and heating fan blades, enables the other fan blade to rotate synchronously. Synchronous driving of the cooling and heating fan blades can be achieved with a single drive unit and speed-changing device, eliminating the need for two independent motors and reducing the installation space required for the integrated fan blade system. When the drive unit rotates one of the cooling and heating fan blades in the forward direction, the speed-changing device can drive the other fan blade to rotate, allowing the heating fan blade to rotate at a low speed to heat the inner liner. The internal airflow is slightly agitated to achieve a uniform temperature field without causing adverse effects on food cooking due to excessive airflow, thus improving cooking quality. At this time, the cooling fan blades can rotate synchronously to remove heat from the machine's interior, preventing overheating and damage to components. The drive device drives one of the cooling fan blades and the heating fan blades to rotate in opposite directions. The speed change device can drive the other fan blade to rotate and adjust the speed ratio after switching between forward and reverse rotation. By driving the heating fan blade to rotate at high speed, the airflow is enhanced, thereby achieving rapid heating and cooking of food. At the same time, the cooling fan blades rotate synchronously and remove heat from the machine's interior, improving cooking efficiency. Attached Figure Description

[0057] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] In related technologies, a microwave-steam-grill combo includes an inner cavity, cooling fan blades, and heating fan blades. During operation, the internal electronic components and heating devices generate a large amount of heat. The cooling fan blades, through forced convection, quickly expel the hot air accumulated around key components such as circuit boards and power modules from the machine body, thereby ensuring that various electronic components and internal mechanical structures are always within the preset safe operating temperature range. This not only ensures the stability of the entire machine during long-term operation but also significantly improves the service life and safety performance of the equipment. When the baking function is activated, the heating fan blades begin to operate. By rotating and stirring the airflow, the heating fan blades continuously and evenly blow the high-temperature air generated by the heating element or heating plate to all areas of the inner cavity. This active hot air circulation mechanism allows heat to fully coat the surface of the food, effectively improving heat exchange efficiency and promoting even heating of the food. This shortens the heating time while improving the color and texture of the food.

[0060] However, since the cooling fan blades and heating fan blades need to be driven by separate motors, the structural design is complex, requiring different control systems and occupying more internal space, which poses a challenge to the overall compact and lightweight design.

[0061] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0062] Combination Figures 1 to 7 This application provides an integrated fan blade system, including:

[0063] The driving device 100 is used to drive one of the heat dissipation fan blade 500 and the heating fan blade 600 of the cooking equipment to rotate in the forward or reverse direction. The heat dissipation fan blade 500 is used to blow the heat generated inside the cooking equipment to the outside of the cooking equipment, and the heating fan blade 600 is used to form diffused convection hot air inside the inner liner 300 of the cooking equipment.

[0064] The speed change device 200 is used to be set between the cooling fan blade 500 and the heating fan blade 600 to link the cooling fan blade 500 and the heating fan blade 600. The speed change device 200 is used to adjust the speed ratio between the cooling fan blade 500 and the heating fan blade 600 before and after switching between forward and reverse rotation when one of the cooling fan blade 500 and the heating fan blade 600 switches between forward and reverse rotation.

[0065] By adopting the above technical solution, the drive device 100 is used to drive the cooling fan blades 500 to rotate forward or backward, and the speed change device 200 is used to synchronize the rotation of the heating fan blades 600 when the cooling fan blades 500 rotate. When the drive device 100 drives the cooling fan blades 500 to rotate forward, the speed change device 200 drives the heating fan blades 600 to rotate synchronously in the forward direction. At this time, the speeds of the cooling fan blades 500 and the heating fan blades 600 are the same. When the drive device 100 drives the cooling fan blades 500 to rotate in the reverse direction, the speed change device 200... The device 200 drives the heating fan blade 600 to rotate in the forward direction. At this time, the rotation speed of the heating fan blade 600 is higher than that of the cooling fan blade 500. When the cooling fan blade 500 rotates in the reverse direction, the rotation speed of the heating fan blade 600 is higher than that of the heating fan blade 600 rotating in the forward direction. The rotation speeds of the cooling fan blade 500 in the forward and reverse directions are the same. When it is necessary to slowly heat the food, the cooling fan blade 500 is driven to rotate in the forward direction. When it is necessary to quickly cook the food, the cooling fan blade 500 is driven to rotate in the reverse direction.

[0066] In other embodiments, the speed of the cooling fan blade 500 can also be changed by the speed change device 200. For example, the speed of the cooling fan blade 500 when rotating forward can be higher than the speed of the cooling fan blade 500 when rotating backward, so that the cooling fan blade 500 can meet different heat dissipation requirements under different speed conditions.

[0067] When cooking food, the drive unit 100 drives the cooling fan blades 500 to rotate forward, and the speed change device 200 drives the heating fan blades 600 to rotate forward. The heating fan blades 600 rotate at low speed to evenly cover the interior of the inner liner 300 with hot air, achieving slow and even heating of the food. At the same time, the cooling fan blades 500 can remove heat from the inside of the machine to prevent overheating and damage to parts. When the drive unit 100 drives the cooling fan blades 500 to rotate in the opposite direction, the speed change device 200 drives the heating fan blades 600 to rotate forward. The heating fan blades 600 rotate at high speed to quickly heat the food. The rotation and stirring of the heating fan blades 600 creates diffused convection hot air in the inner liner 300, ensuring even heat coverage and improving heating efficiency. The synchronous driving of the cooling fan blades 500 and the heating fan blades 600 is achieved by a single drive unit 100 and a speed change device 200, eliminating the need for two independent motors and reducing the installation space required for the integrated fan blade system.

[0068] In this embodiment, the drive device 100 is a motor. The motor is connected to the cooking equipment and is positioned above the cooling fan blade 500. The output shaft of the motor is connected to the shaft of the cooling fan blade 500. The motor can rotate in both directions, thereby driving the cooling fan blade 500 to rotate synchronously in either direction.

[0069] In other embodiments, the drive unit 100 may be replaced by a hydraulic motor and a pneumatic motor, which are connected to the cooking equipment, and the shaft of the cooling fan blade 500 is connected to the drive end of the hydraulic motor and the pneumatic motor, so that the hydraulic motor and the pneumatic motor can also drive the cooling fan blade 500 to rotate forward or backward.

[0070] The transmission device 200 includes:

[0071] The active mechanism 210 is mounted on one of the cooling fan blades 500 and the heating fan blades 600, and rotates synchronously with one of the cooling fan blades 500 and the heating fan blades 600.

[0072] Driven mechanism 220 is disposed on the other of cooling fan blade 500 and heating fan blade 600, and drives the other of cooling fan blade 500 and heating fan blade 600 to rotate.

[0073] The switching mechanism 230 is connected between the driving mechanism 210 and the driven mechanism 220. When the driving mechanism 210 switches between forward and reverse rotation, the switching mechanism 230 adjusts the speed ratio of the driven mechanism 220 before and after the switch.

[0074] In this embodiment, the active mechanism 210 is mounted on the cooling fan blade 500 and rotates synchronously with the cooling fan blade 500. The driven mechanism 220 is mounted on the heating fan blade 600 and drives the heating fan blade 600 to rotate. The driven mechanism 220 is configured as the drive shaft of the heating fan blade 600. When the driving device 100 drives the cooling fan blade 500 to rotate in the forward direction, the active mechanism 210 rotates synchronously with the cooling fan blade 500, and the driven mechanism 220 drives the heating fan blade 600 to rotate synchronously in the forward direction through the switching mechanism 230. At this time, the heating fan blade 600 is in a low-speed rotation state. When the driving device 100 drives the cooling fan blade 500 to rotate in the reverse direction, the active mechanism 210 rotates synchronously with the cooling fan blade 500, and the driven mechanism 220 drives the heating fan blade 600 to rotate in the forward direction through the switching mechanism 230. At this time, the heating fan blade 600 is in a high-speed rotation state.

[0075] In this embodiment, the active mechanism 210 consists of an active wheel 211, a driven wheel 212, and a belt 213. The active wheel 211 is connected to the shaft of the cooling fan blade 500. The switching mechanism 230 is disposed between the driven wheel 212 and the drive shaft of the heating fan blade 600. The belt 213 is wound between the active wheel 211 and the driven wheel 212. When the active wheel 211 rotates synchronously with the cooling fan blade 500, it can drive the driven wheel 212 to rotate through the belt 213, thereby driving the drive shaft of the heating fan blade 600 to rotate through the switching mechanism 230, so as to realize the driving of the heating fan blade 600.

[0076] In other embodiments, the active mechanism 210 can also be replaced by a first gear, a second gear, and a chain. By connecting the first gear to the shaft of the heat dissipation fan blade 500, setting the switching mechanism 230 between the second gear and the drive shaft of the heating fan blade 600, and winding the chain between the first gear and the second gear, the driving of the heating fan blade 600 can also be achieved.

[0077] By adopting the above technical solution, when cooking food, the drive device 100 drives the cooling fan blades 500 to rotate forward, and the drive wheel 211 rotates synchronously with the cooling fan blades 500. The drive wheel 211 drives the driven wheel 212 to rotate via the belt 213, which in turn drives the driven mechanism 220 to rotate via the switching mechanism 230. The driven mechanism 220 drives the heating fan blades 600 to rotate forward. By rotating the heating fan blades 600 at low speed, hot air is evenly distributed inside the inner pot 300, achieving even and slow heating of the food. At the same time, the cooling fan blades 500 can remove heat from inside the machine, preventing damage to parts due to overheating. The drive device 100 also drives the cooling fan blades 500 to rotate in the opposite direction to dissipate heat. The fan blade 500 drives the drive wheel 211 to rotate in the opposite direction. The drive wheel 211 drives the driven wheel 212 to rotate via the belt 213, which in turn drives the driven mechanism 220 to rotate via the switching mechanism 230. This, in turn, drives the heating fan blade 600 to rotate in the forward direction. The high-speed rotation of the heating fan blade 600 achieves rapid and uniform heating of food, improving heating efficiency. The elasticity of the belt 213 itself can effectively absorb the impact and vibration generated when the motor starts, reduce transmission noise, and extend the service life of the motor and other components such as the fan blade. When the cooling fan blade 500 is accidentally jammed, the belt 213 may slip, thereby cutting off the power transmission and effectively preventing the motor from burning out due to overload, thus improving the safety and reliability of the system.

[0078] Switching mechanism 230 includes:

[0079] Ratchet assembly 231 is disposed between the driving mechanism 210 and the driven mechanism 220. When the driving mechanism 210 rotates in the forward direction, the ratchet assembly 231 drives the driven mechanism 220 to rotate. When the driving mechanism 210 rotates in the reverse direction, the ratchet assembly 231 stops driving the driven mechanism 220 to rotate.

[0080] The gear reduction assembly 232 is disposed between the driving mechanism 210 and the ratchet assembly 231. When the driving mechanism 210 rotates in the opposite direction, the gear reduction assembly 232 drives the driven mechanism 220 to rotate and adjusts the speed ratio of the driven mechanism 220 before and after switching.

[0081] By adopting the above technical solution, when the drive device 100 drives the cooling fan blade 500 to rotate in the forward direction, the active mechanism 210 rotates synchronously with the cooling fan blade 500. The active mechanism 210 drives the ratchet assembly 231 to rotate, the ratchet assembly 231 drives the driven mechanism 220 to rotate, and the driven mechanism 220 drives the heating fan blade 600 to rotate in the forward direction. At this time, the heating fan blade 600 is rotating at a low speed, and the cooling fan blade 500 and the heating fan blade 600 rotate at the same speed. When the drive device 100 drives the cooling fan blade 500 to rotate in the reverse direction, the cooling fan blade 500 drives the active mechanism 210 to rotate in the forward direction, the ratchet assembly 231 stops driving the driven mechanism 220 to rotate, and the gear reduction assembly 232 drives the driven mechanism 220 to rotate. The ratchet assembly 231 and gear reduction assembly 232 are used to drive the heating fan blade 600 to rotate in the forward direction. At this time, the rotation speed of the heating fan blade 600 is higher than that of the cooling fan blade 500. When the cooling fan blade 500 rotates in the reverse direction, the rotation speed of the heating fan blade 600 is higher than that of the cooling fan blade 500 rotating in the forward direction. When food needs to be heated slowly, the cooling fan blade 500 is driven to rotate in the forward direction. When food needs to be cooked quickly, the cooling fan blade 500 is driven to rotate in the reverse direction. By using the ratchet assembly 231 and gear reduction assembly 232, the structure is simple, the driving effect of the heating fan blade 600 is improved, and the ratchet assembly 231 and gear reduction assembly 232 do not occupy a large installation space, thus reducing the space occupied by the integrated fan blade system.

[0082] Ratchet assembly 231 includes:

[0083] The first pawl 2311 is rotatably mounted on the active mechanism 210;

[0084] Ratchet 2312 is connected to driven mechanism 220. When driven mechanism 210 rotates in the forward direction, first pawl 2311 engages with ratchet 2312, so that ratchet 2312 drives driven mechanism 220 to rotate. When driven mechanism 210 rotates in the reverse direction, first pawl 2311 disengages from ratchet 2312, so that ratchet 2312 drives first pawl 2311 to rotate multiple times at the hinge on driven mechanism 210, thereby stopping the drive of driven mechanism 220 to rotate.

[0085] In this embodiment, the first pawl 2311 is rotatably connected to the driven wheel 212 of the active mechanism 210, and the ratchet 2312 is sleeved on the drive shaft that is fixedly connected to the heating fan blade 600.

[0086] By adopting the above technical solution, when the driving device 100 drives the cooling fan blades 500 to rotate in the forward direction, the cooling fan blades 500 drive the driving wheel 211 to rotate. The driving wheel 211 drives the driven wheel 212 to rotate via the belt 213. When the first pawl 2311 rotates with the driven wheel 212, the first pawl 2311 engages in the tooth groove of the ratchet 2312 to drive the ratchet 2312 to rotate, thereby causing the ratchet 2312 to drive the driven mechanism 220 to rotate, so that the driven mechanism 220 drives the heating fan blades 600 to rotate in the forward direction. Through the low-speed rotation of the heating fan blades 600, the food is slowly and evenly heated. When the driving device 100 drives the cooling fan blades 500 to rotate in the reverse direction, the driving wheel 211 rotates synchronously with the cooling fan blades 500. The belt 213 drives the driven wheel 212 to rotate, thereby causing the first pawl 2311 to slide on the ratchet 2312. At this time, the first pawl 2311 can rotate on the driven wheel 212, so that the first pawl 2311 will not engage with the tooth groove, thus preventing the first pawl 2311 from driving the ratchet 2312 to rotate, and causing the ratchet 2312 to stop driving the driven mechanism 220 to rotate. When the driven wheel 212 rotates forward, the first pawl 2311 engages with the ratchet 2312 and drives the ratchet 2312 to rotate synchronously. When the driven wheel 212 rotates in reverse, the first pawl 2311 automatically disengages from the ratchet 2312, thereby stopping the drive of the ratchet 2312 to rotate. This process achieves unidirectional transmission through the mechanical characteristics of the mechanism itself, without the need for additional control devices.

[0087] Gear reduction assembly 232 includes:

[0088] The center wheel 2321 is mounted on the ratchet 2312 so as to rotate synchronously with the ratchet 2312;

[0089] The traveling wheel 2322 meshes with the center wheel 2321.

[0090] The speed reduction component 2323 is mounted on the traveling wheel 2322;

[0091] When the driving mechanism 210 rotates in the forward direction, the ratchet 2312 drives the center wheel 2321 to rotate in the forward direction, and the reducer 2323 drives the traveling wheel 2322 to move circumferentially along the axis of the driven mechanism 220, so as to drive the driven mechanism 220 to rotate in the forward direction. When the driving mechanism 210 rotates in the reverse direction, the reducer 2323 drives the traveling wheel 2322 to rotate in the reverse direction at the same position, so that the traveling wheel 2322 drives the center wheel 2321 to rotate in the forward direction, thereby making the driven mechanism 220 rotate in the forward direction.

[0092] In this embodiment, the center wheel 2321 is sleeved and fixedly connected to the drive shaft of the heating fan blade 600, and the center wheel 2321 is located below the ratchet 2312.

[0093] In this embodiment, the diameter of ratchet 2312 is larger than the diameter of center wheel 2321, and the diameter of center wheel 2321 is larger than the diameter of travel wheel 2322.

[0094] By adopting the above technical solution, the drive device 100 drives the cooling fan blades 500 to rotate in the forward direction. The cooling fan blades 500 drive the drive wheel 211 to rotate. When the drive wheel 211 drives the driven wheel 212 to rotate via the belt 213, the driven wheel 212 can drive the center wheel 2321 to rotate, thereby driving the heating fan blades 600 to rotate in the forward direction. At the same time, the reducer 2323 drives the traveling wheel 2322 to move circumferentially along the drive shaft of the heating fan blades 600, realizing slow and uniform heating of the food. The drive device 100 drives the cooling fan blades 500 to rotate in the reverse direction, and the drive wheel 211 drives the driven wheel 212 to rotate via the belt 213. The belt 213 drives the driven wheel 212 to rotate in the opposite direction, and the reducer 2323 drives the traveling wheel 2322 to rotate in the same position in the opposite direction. The traveling wheel 2322 drives the center wheel 2321 to rotate in the forward direction, thereby driving the driven mechanism 220 to rotate in the forward direction. The driven mechanism 220 drives the heating fan blade 600 to rotate in the forward direction, realizing rapid heating of food. When the driven wheel 212 rotates in the forward or reverse direction, the driven mechanism 220 is driven to rotate through the pure mechanical linkage of the reducer 2323, the traveling wheel 2322 and the center wheel 2321, without the need for additional control devices.

[0095] The speed reducer 2323 includes a gear ring 2324 and a locking part 2325. The gear ring 2324 is disposed on the driving mechanism 210, and the locking part 2325 is disposed between the driven mechanism 220 and the traveling wheel 2322. The locking part 2325 is used to restrict or release the traveling wheel 2322 from rotating in the same position. The traveling wheel 2322 is engaged between the center wheel 2321 and the gear ring 2324.

[0096] When the driving mechanism 210 rotates in the forward direction, the locking part 2325 disengages from restricting the traveling wheel 2322, the ratchet 2312 drives the center wheel 2321 to rotate in the forward direction, and the driving mechanism 210 drives the gear ring 2324 to rotate in the forward direction, so that the traveling wheel 2322 moves circumferentially along the axis of the driven mechanism 220; when the driving mechanism 210 rotates in the reverse direction, the locking part 2325 restricts the traveling wheel 2322, so that the gear ring 2324 drives the traveling wheel 2322 to rotate in the reverse direction at the same position, so that the traveling wheel 2322 drives the center wheel 2321 to rotate in the forward direction.

[0097] In this embodiment, the toothed ring 2324 is connected to the driven wheel 212, and the toothed ring 2324 and the driven wheel 212 are coaxially arranged.

[0098] By adopting the above technical solution, the drive device 100 drives the cooling fan blades 500 to rotate in the forward direction. The cooling fan blades 500 drive the drive wheel 211 to rotate. The drive wheel 211 drives the driven wheel 212 to rotate via the belt 213. The first pawl 2311 drives the ratchet 2312 to rotate. The ratchet 2312 drives the center wheel 2321 to rotate, thereby driving the heating fan blades 600 to rotate in the forward direction. At this time, the locking part 2325 disengages from the restricting wheel 2322. The center wheel 2321, the wheel 2322, and the gear ring 2324 rotate synchronously, and there is no relative rotation between the three. The wheel 2322 can move circumferentially along the axis of the drive shaft of the heating fan blades 600. The drive device 100 drives the cooling fan blades 500 to rotate in the reverse direction. The driving wheel 211 drives the driven wheel 212 to rotate in the opposite direction via the belt 213. At this time, the locking part 2325 can restrict the traveling wheel 2322 to the same position, so that the traveling wheel 2322 rotates in the same position. The traveling wheel 2322 can drive the center wheel 2321 to rotate in the forward direction, thereby driving the heating fan blade 600 to rotate in the forward direction, realizing rapid heating of food. The center wheel 2321, the traveling wheel 2322 and the gear ring 2324 are meshed, and power transmission is achieved through rigid meshing between the tooth profiles, resulting in high transmission efficiency. The meshing between the teeth ensures a strict speed ratio relationship, and the output speed and torque are stable and controllable, with high positioning accuracy and good repeatability. At the same time, the gear has strong load-bearing capacity, good impact resistance, compact overall structure and long service life, and is suitable for power transmission needs under high load, high precision and harsh working conditions.

[0099] Locking unit 2325 includes:

[0100] The second pawl 2326 is rotatably mounted on the mounting bracket 700 of the driven mechanism 220;

[0101] A locking rod 2327 is sleeved on and rotatably mounted on the driven mechanism 220. A limiting rod 2328 is provided on the traveling wheel 2322 and rotatably mounted on the locking rod 2327.

[0102] When the driving mechanism 210 rotates in the forward direction, the gear ring 2324 rotates in the forward direction, and the traveling wheel 2322 moves circumferentially along the axis of the driven mechanism 220. The traveling wheel 2322 drives the limiting rod 2328 to move circumferentially along the axis of the driven mechanism 220. The limiting rod 2328 drives the locking rod 2327 to rotate in the forward direction, so that the locking rod 2327 abuts against the second pawl 2326 multiple times, and drives the second pawl 2326 to rotate at the hinge on the mounting bracket 700 to disengage from the traveling wheel 2322. When the driving mechanism 210 rotates in the reverse direction, the gear ring 2324 rotates in the reverse direction, and the limiting rod 2328 drives the locking rod 2327 to engage with the second pawl 2326 to prevent the limiting rod 2328 from moving circumferentially along the axis of the driven mechanism 220. This causes the traveling wheel 2322 to drive the limiting rod 2328 to rotate in the reverse direction on the locking rod 2327, so that the traveling wheel 2322 rotates in the same position in the reverse direction.

[0103] In this embodiment, the mounting bracket 700 is connected to the inner pot 300 of the cooking equipment, the drive shaft of the heating fan blade 600 passes through and is rotatably connected to the mounting bracket 700, and the mounting bracket 700 is disposed between the driven wheel 212 and the heating fan blade 600; the locking rod 2327 is sleeved and rotatably connected to the drive shaft of the heating fan blade 600.

[0104] By adopting the above technical solution, the first pawl 2311 on the driven wheel 212 drives the ratchet 2312 to rotate, the ratchet 2312 drives the center wheel 2321 to rotate in the forward direction, and the center wheel 2321 drives the driven mechanism 220 to rotate. At this time, the traveling wheel 2322 moves circumferentially along the axis of the drive shaft of the heating fan blade 600. The traveling wheel 2322 drives the locking lever 2327 to repeatedly abut against the second pawl 2326, so that the second pawl 2326 rotates continuously on the mounting bracket 700, so that the second pawl 2326 will not prevent the locking lever 2327 from moving circumferentially along the axis of the drive shaft of the heating fan blade 600, so that the ratchet 2312 and the center wheel 2321 drive the heating fan blade 600 to rotate. When the driven wheel 212 rotates in the reverse direction, the gear ring 2324 drives the traveling wheel 2322 to rotate in the reverse direction. At this time, the second pawl 2326 abuts against the locking lever 2327, preventing the locking lever 2327 from rotating. 327 moves circumferentially along the axis of the drive shaft of the heating fan blade 600, thereby causing the locking lever 2327 to restrict the travel wheel 2322 to rotate in the same position. This causes the travel wheel 2322 to drive the center wheel 2321 to rotate the heating fan blade 600 in the forward direction. Since the diameter of the toothed ring 2324 is larger than the diameter of the travel wheel 2322, the travel wheel 2322 rotates multiple times when the toothed ring 2324 rotates once, thereby accelerating the rotation speed of the heating fan blade 600. When the driven wheel 212 rotates in the forward direction, the locking lever 2327 and the second pawl 2326 disengage, allowing the travel wheel 2322 to move circumferentially. When the driven wheel 212 rotates in the reverse direction, the locking lever 2327 and the second pawl 2326 restrict the travel wheel 2322 to be fixed in the same position, so that the input reverse force is converted into the reverse force of the travel wheel 2322 itself, and the center wheel 2321 is kept rotating in the forward direction.

[0105] The active mechanism 210 is provided with a receiving port 400, the first pawl 2311 is hinged to the inner wall of the receiving port 400, and the ratchet 2312 is rotatably disposed inside the receiving port 400.

[0106] In this embodiment, the receiving port 400 is disposed on the driven wheel 212 of the active mechanism 210. The receiving port 400 is circular. The ratchet 2312 is coaxially disposed with the receiving port 400. The ratchet 2312 and the receiving port 400 have the same thickness. The upper surface of the ratchet 2312 is flush with the upper edge of the receiving port 400, and the lower surface of the ratchet 2312 is flush with the lower edge of the receiving port 400.

[0107] By adopting the above technical solution, by setting the first pawl 2311 and ratchet 2312 inside the receiving port 400, the first pawl 2311 and ratchet 2312 can utilize the space of the driven wheel 212, thereby reducing the space occupied by the driven wheel 212, the first pawl 2311 and ratchet 2312, and the space occupied by the driven wheel 212, the first pawl 2311 and ratchet 2312 installed in the cooking device, and indirectly reducing the overall space occupied by the cooking device.

[0108] In this embodiment, the integrated fan blade system further includes a first reset component, which is disposed between the first pawl 2311 and the driven wheel 212. The first reset component is a first torsion spring, which is sleeved on the rotating shaft of the first pawl 2311. One end of the first torsion spring is connected to the first pawl 2311, and the other end of the first torsion spring is connected to the driven wheel 212.

[0109] By adopting the above technical solution and by setting the first reset member, when the driven wheel 212 rotates in the forward direction, the first pawl 2311 can cooperate with the ratchet 2312 by relying on the elastic force of the first reset member, preventing the first pawl 2311 from disengaging from the ratchet 2312 when driving the ratchet 2312 to rotate, thereby improving the cooperation strength between the first pawl 2311 and the ratchet 2312; when the driven wheel 212 rotates in the reverse direction, the ratchet 2312 can drive the first pawl 2311 to rotate on the inner wall of the receiving port 400 against the elastic force of the first reset member, so that when the driven wheel 212 rotates in the reverse direction, it will not drive the ratchet 2312 to rotate synchronously.

[0110] In other embodiments, the first reset member can also be replaced by a first tension spring. One end of the first tension spring is connected to the first pawl 2311, and the other end of the first tension spring is connected to the driven wheel 212. When the driven wheel 212 rotates forward, the first tension spring is in its natural state, and the first pawl 2311 engages with the teeth of the ratchet 2312 to drive the ratchet 2312 to rotate. When the driven wheel 212 rotates in reverse, the first pawl 2311 follows the rotation of the driven wheel 212. The first pawl 2311 continuously abuts against the ratchet 2312, causing the first tension spring to be continuously stretched. The first pawl 2311 will not engage with the ratchet 2312, thus not driving the ratchet 2312 to rotate.

[0111] In this embodiment, the integrated fan blade system further includes a second reset component, which is disposed between the second pawl 2326 and the mounting bracket 700. The second reset component is a second torsion spring, which is sleeved on the rotating shaft of the second pawl 2326. One end of the second torsion spring is connected to the second pawl 2326, and the other end of the second torsion spring is connected to the mounting bracket 700.

[0112] By adopting the above technical solution and by setting the second reset member, when the driven wheel 212 rotates in the forward direction, the gear ring 2324 rotates in the forward direction, and the traveling wheel 2322 moves circumferentially along the axis of the driven mechanism 220. The traveling wheel 2322 drives the limiting rod 2328 to move circumferentially along the axis of the driven mechanism 220. The limiting rod 2328 drives the locking rod 2327 to rotate in the forward direction, so that the locking rod 2327 abuts against the second pawl 2326 multiple times, and drives the second pawl 2326 to resist the elastic force of the second reset member and rotate at the hinge on the mounting bracket 700 to disengage from the limiting traveling wheel 2322; the driven wheel 212 rotates in the reverse direction. When rotating, the gear ring 2324 rotates in the opposite direction, and the limiting rod 2328 drives the locking rod 2327 to engage with the second pawl 2326. The second pawl 2326 can prevent the limiting rod 2328 from moving circumferentially along the axis of the driven mechanism 220 by the elastic force of the second reset member. This causes the traveling wheel 2322 to drive the limiting rod 2328 to rotate in the opposite direction on the locking rod 2327, thereby driving the traveling wheel 2322 to rotate in the opposite direction at the same position. This indirectly improves the engagement strength between the second pawl 2326 and the locking rod 2327 when the driven wheel 212 rotates in the opposite direction, preventing the second pawl 2326 and the locking rod 2327 from disengaging.

[0113] In other embodiments, the second reset member can be replaced by a second tension spring, one end of which is connected to the second pawl 2326, and the other end of which is connected to the mounting bracket 700. When the driven mechanism 220 rotates forward, the second tension spring is in its natural state, and the second pawl 2326 engages with the toothed groove of the locking rod 2327 to drive the locking rod 2327 to rotate. When the driven mechanism 220 rotates in reverse, the second pawl 2326 follows the driven mechanism 220 to rotate, and the second pawl 2326 continuously abuts against the locking rod 2327, causing the second tension spring to be continuously stretched. The second pawl 2326 will not engage with the locking rod 2327, thus preventing the locking rod 2327 from rotating.

[0114] This application also provides a cooking device, including an inner pot 300 and an integrated fan blade system disposed on the inner pot 300.

[0115] The specific structure of the integrated fan blade system has been described in detail in the above embodiments, and will not be repeated here.

[0116] In this embodiment, the cooking device is a microwave-steam-grill combination machine. In other embodiments, the cooking device may also be an oven, a steam oven, an integrated stove, a stove-steam-grill combination machine, a steam-grill combination machine, a microwave-steam combination machine, a microwave-grill combination machine, or a steam-grill-fry combination machine, etc.

[0117] Cooking equipment also includes:

[0118] The air duct structure 800 is installed on the inner liner 300, and the air duct structure 800 is provided with an air inlet 810 and an air outlet 820.

[0119] Cooling fan blade 500 is installed inside the air duct structure 800;

[0120] Heated fan blade 600, which is located inside the inner liner 300;

[0121] The drive unit 100 is located outside the air duct structure 800, and the speed change unit 200 is located inside or outside the air duct structure 800.

[0122] In this embodiment, when the transmission device 200 is located inside the air duct structure 800, the cooling fan blades 500 rotate to introduce cold air from the outside through the air inlet 810, and the heat generated by the drive wheel 211, driven wheel 212, belt 213 and other components is discharged from the air outlet 820 through the air duct structure 800; when the transmission device 200 is located outside the air duct structure 800, it can dissipate heat on its own without the need for an additional heat dissipation channel.

[0123] The cooking equipment provided in this application adopts an integrated fan blade system. When food needs to be cooked, the drive device 100 drives the cooling fan blades 500 to rotate forward. The cooling fan blades 500 drive the drive wheel 211 to rotate. The drive wheel 211 drives the driven wheel 212 to rotate via the belt 213. The first pawl 2311 on the driven wheel 212 drives the ratchet 2312 to rotate. The ratchet 2312 drives the center wheel 2321 to rotate forward. The center wheel 2321 drives the driven mechanism 220 to rotate. When the traveling wheel 2322 moves circumferentially along the axis of the drive shaft of the heating fan blade 600, the traveling wheel 2322 drives the locking lever 2327 to repeatedly abut against the second pawl 2326, causing the second pawl 2326 to rotate continuously on the mounting bracket 700. This ensures that the second pawl 2326 does not prevent the locking lever 2327 from moving circumferentially along the axis of the drive shaft of the heating fan blade 600, so that the ratchet 2312 and the center wheel 2321 drive the heating fan blade 600 to rotate in the forward direction. Low-speed rotation ensures that hot air evenly covers the interior of the inner liner 300, achieving uniform and slow heating of the food. The drive device 100 drives the cooling fan blades 500 to rotate in the opposite direction. The cooling fan blades 500 drive the drive wheel 211 to rotate. The drive wheel 211 drives the driven wheel 212 to rotate in the opposite direction via the belt 213. The gear ring 2324 drives the traveling wheel 2322 to rotate in the opposite direction. At this time, the second pawl 2326 abuts against the locking rod 2327, preventing the locking rod 2327 from moving circumferentially along the axis of the drive shaft of the heating fan blade 600. This restricts the traveling wheel 2322 from rotating in the same position, allowing the traveling wheel 2322 to drive the center wheel 2321 to rotate the heating fan blade 600 in the forward direction. The high-speed rotation of the heating fan blade 600 achieves rapid and uniform heating of the food, improving heating efficiency. The cooling fan blades 500 and the heating fan blades 600 are driven synchronously by a single drive device 100, eliminating the need for two independent motors and reducing the installation space of the integrated fan blade system.

[0124] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein.
