Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to a panel translation and flipping device and a cooking device. Background Technology

[0002] The control panel components of cooking appliances such as microwave ovens and ovens are mostly fixed to the body. If the electronic components on the control panel components are damaged, the outer shell needs to be removed and the control board or electronic components taken out from the inside for replacement or repair. The repair is difficult and the workload is large, especially for built-in products.

[0003] In addition, as users' demands for products continue to increase, microwave ovens and ovens with steam baking, steam cooking or steam humidification functions are gradually entering more and more homes. Products with steam baking, steam cooking or steam humidification functions all have water tanks. The water tank being placed outside would affect the consistency of the product's appearance. Therefore, the water tank is usually installed inside the outer shell. However, it is inconvenient to add water or clean the built-in water tank. Utility Model Content

[0004] In view of this, the present invention provides a panel translation and flipping device and a cooking device to solve the problems of inconvenient maintenance of the panel components of the cooking device in the prior art, and inconvenient water tank filling or cleaning.

[0005] In a first aspect, this utility model provides a panel translation and flipping device, comprising:

[0006] Panel components;

[0007] The drive device includes a drive assembly and a transmission assembly disposed between the drive assembly and the panel assembly. The transmission assembly includes a transmission gear and a transmission rack. The transmission gear includes a first external tooth and a second external tooth that are coaxial and move synchronously. The transmission rack includes a first rack and a second rack.

[0008] The first external tooth meshes with the first rack and is adapted to drive the first rack to move at a first speed; the second external tooth meshes with the second rack and is adapted to drive the second rack to move at a second speed, wherein the second speed is greater than the first speed;

[0009] The first rack is movably connected to the first connection point of the panel assembly. The transmission assembly also includes a connecting rod, one end of which is movably connected to the second connection point of the second rack, and the other end of which is movably connected to the third connection point of the panel assembly. The first connection point, the second connection point, and the third connection point form a triangle.

[0010] When the drive device is working, the drive component drives the transmission gear to rotate, and the transmission rack drives the panel assembly to move under the drive of the transmission gear. During the movement, the panel assembly will rotate around the first connection point as the center of rotation under the action of the speed difference between the first rack and the second rack.

[0011] Beneficial effects: When components on the panel assembly are damaged or water needs to be added to the water tank, the drive component rotates the transmission gear, which in turn drives the transmission rack to move the control panel assembly outward. During this movement, the panel assembly flips upward under the speed difference between the first and second racks. The flipped-out panel assembly is easier to disassemble, inspect, and replace, improving the convenience of control panel maintenance. Furthermore, the flipped-out panel assembly makes it easier to remove the water tank hidden behind it, facilitating water changes or cleaning. This enhances the user experience, increases the product's market competitiveness, and solves the problems of inconvenient panel assembly maintenance and inconvenient water tank filling or cleaning in existing cooking equipment. In addition, this embodiment uses a coaxial and synchronously moving first and second external gear design for the transmission gear. The speed difference between the first and second racks, driven by the coaxial gear, drives the panel assembly to flip during translation. This results in higher precision, faster response, higher reliability, lower cost, and a simpler overall device structure, occupying less space and facilitating installation and layout.

[0012] In one alternative implementation, the panel assembly has an initial state and a flipped state, wherein when the panel assembly is in the initial state, the first connection point is higher than the third connection point.

[0013] Beneficial effect: Under normal conditions, the first connection point is located above the third connection point, so that when the first external tooth and the second external tooth drive the first rack and the second rack to move the panel assembly away from the transmission gear, they can simultaneously flip upwards, thereby opening the opening of the outer shell.

[0014] In one optional embodiment, the first external tooth and the second external tooth have the same module, the number of teeth of the first external tooth is z1, the number of teeth of the second external tooth is z2, and z1 < z2.

[0015] Alternatively, the first external tooth and the second external tooth have the same number of teeth, the module of the first external tooth is m1, the module of the second external tooth is m2, and m1 < m2.

[0016] Beneficial effect: By adopting a design where the number of teeth of the first external tooth is less than the number of teeth of the second external tooth, or the module of the first external tooth is less than the module of the second external tooth, the moving speed of the first rack can be less than the moving speed of the second rack, ensuring that the panel assembly can rotate synchronously under the action of the speed difference between the first rack and the second rack during the translation process.

[0017] In one alternative embodiment, the first rack is hinged to the panel assembly, and the connecting rod is hinged to the second rack and the panel assembly, respectively.

[0018] Beneficial effects: The first rack and panel assembly, as well as the connecting rod and the second rack and panel assembly, are all connected by hinges, which is highly reliable and flexible. This effectively avoids mechanical jamming of the panel assembly during movement and flipping, and improves the flexibility and smoothness of the entire device's movement.

[0019] In one alternative implementation, the first rack includes:

[0020] Base;

[0021] The meshing transmission part is fixedly mounted on the base;

[0022] The hinged connection is fixedly installed at one end of the base near the panel assembly;

[0023] The hinged connection part has a first hinge hole at its end and a second hinge hole on the panel assembly. The first hinge hole and the second hinge hole are connected by a first hinge shaft.

[0024] Beneficial effects: The base, meshing transmission part, and hinge connection part are integrated structures. The base is a strip frame structure, the meshing transmission part is a strip plate structure with several racks, the meshing transmission part is fixedly installed on one side of the base, and the hinge connection part is a connecting rod fixedly installed on the end of the base. One end of the connecting rod is integrally connected to the base, and the other end is provided with a first hinge hole. The panel assembly and the first rack are hinged through the first hinge shaft. The reliability and flexibility of the connection are relatively high.

[0025] In one alternative embodiment, the transmission assembly further includes:

[0026] A transmission bracket, with the first and second racks slidably connected to it, and a position switch provided on the transmission bracket;

[0027] A trigger part is provided on the first or second rack. When the panel assembly moves to the set position, the trigger part triggers the position switch.

[0028] Beneficial effects: By setting position switches and triggers, when the panel assembly moves to the set open or closed position, a corresponding trigger signal is issued, and the control device stops driving, so that the panel assembly is kept in the preset position or angle, avoiding mechanical damage caused by continued driving, and the controllability and safety are higher.

[0029] In one alternative embodiment, the transmission assembly has two sets, which are distributed on both sides of the panel assembly.

[0030] Beneficial effects: By setting two sets of transmission components on both sides of the panel assembly, it is possible to drive the panel assembly to move and flip in a more balanced and stable manner from both sides.

[0031] In one alternative embodiment, the drive device further includes:

[0032] The transmission rod is connected between the two transmission gears of the two sets of transmission components. The drive component is connected to the transmission rod and is suitable for driving the transmission rod to rotate so as to drive the two transmission gears to rotate synchronously.

[0033] Beneficial effects: By setting a transmission rod between the two transmission gears, it is convenient to drive the two transmission gears to rotate synchronously through a set of drive components, thereby ensuring the synchronous movement of the two sets of transmission components. This makes the synchronicity and consistency of the movement of the two sets of transmission components higher, thus effectively ensuring the balance and stability of the panel assembly during movement.

[0034] In one alternative implementation, the driving component includes:

[0035] A drive motor, with a drive gear mounted on its output shaft;

[0036] The reduction gear assembly includes a first reduction gear and a second reduction gear. The first reduction gear meshes with a drive gear, and the second reduction gear is driven between the first reduction gear and the drive gear.

[0037] Beneficial effect: The reduction gear assembly can reduce the high speed of the drive motor output shaft to a set speed range, ensuring that the panel assembly can open and close smoothly.

[0038] Secondly, this utility model also provides a cooking device, comprising:

[0039] The outer casing has an opening on one side;

[0040] The water tank is located inside the outer casing and at the opening.

[0041] In any of the above embodiments of the panel translation and flipping device, the panel assembly is disposed at the opening, and the driving device is disposed inside the housing. The driving device is adapted to drive the panel assembly to flip to open or close the opening. Attached Figure Description

[0066] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0067] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0068] According to an embodiment of the present invention, in one aspect, the present invention provides a panel translation and flipping device, including a panel assembly 1, a driving device, the driving device including a driving component 3, and a transmission component 2 disposed between the driving component 3 and the panel assembly 1, the transmission component 2 including a transmission gear 21 and a transmission rack, the transmission gear 21 including a first external tooth 211 and a second external tooth 212 that are coaxial and move synchronously, the transmission rack including a first rack 22 and a second rack 23; the first external tooth 211 meshes with the first rack 22, adapted to drive the first rack 22 to move at a first speed; the second external tooth 212 meshes with the second rack 23, adapted to drive the second rack 23 to move at a second speed, wherein the second... The speed is greater than the first speed; the first rack 22 is movably connected to the first connection point 101 of the panel assembly 1, and the transmission assembly 2 also includes a connecting rod 24, one end of which is movably connected to the second connection point 102 of the second rack 23, and the other end is movably connected to the third connection point 103 of the panel assembly 1. The first connection point 101, the second connection point 102, and the third connection point 103 form a triangle; when the drive device is working, the drive assembly 3 drives the transmission gear 21 to rotate, and the transmission rack drives the panel assembly 1 to move under the drive of the transmission gear 21. During the movement, the panel assembly 1 will rotate around the first connection point 101 as the center of rotation under the action of the speed difference between the first rack 22 and the second rack 23.

[0069] The above embodiment provides a panel sliding and flipping device that allows the control panel assembly 1 to flip outward. When the components on the panel assembly 1 are damaged or water needs to be added to the water tank 5, the drive assembly 3 rotates through the drive transmission gear 21, driving the transmission rack to move the control panel assembly 1 outward. During the movement, the panel assembly 1 will flip upward under the action of the speed difference between the first rack 22 and the second rack 23. The flipped-out panel assembly 1 is more convenient to disassemble, repair, and replace, improving the convenience of maintenance of the control panel 11. Moreover, the flipped-out panel assembly 1 also makes it easier to remove the water tank 5 hidden behind it, making it convenient to change the water in the water tank 5 or clean the water tank 5. This improves the user experience of the product, increases the market competitiveness of the product, and solves the problems of the inconvenience of repairing the panel assembly 1 of existing cooking equipment and the inconvenience of adding water or cleaning the water tank 5. Furthermore, in this embodiment, the transmission gear 21 adopts a design with coaxial and synchronously moving first external teeth 211 and second external teeth 212, and achieves the flipping of the drive panel assembly 1 during translation by using the speed difference between the first rack 22 and the second rack 23 driven by the coaxial gear. The synchronous movement of the first rack 22 and the second rack 23 has higher precision, faster response speed, higher reliability, and lower cost. Moreover, the overall device structure is simpler, occupies less space, and is more convenient for installation and layout.

[0070] Specifically, in this embodiment, the panel assembly 1 includes a control panel 11 and a panel bracket 12. The control panel 11 is detachably mounted on the panel bracket 12, and electronic components such as an electronic control board are installed between the control panel 11 and the panel bracket 12. The transmission assembly 2 is movably connected to the panel bracket 12. The movable connection includes, but is not limited to, hinged, elastic, and flexible connections. Preferably, the first rack 22 is hinged to the panel assembly 1, and the connecting rod 24 is hinged to the second rack 23 and the panel assembly 1.

[0071] Furthermore, when the transmission gear 21 is driven by the drive assembly 3 to rotate in the first direction, the first rack 22 and the second rack 23 drive the panel assembly 1 to move away from the transmission gear 21, and the panel assembly 1 flips upward with the first connection point 101 as the center; when the transmission gear 21 is driven by the drive assembly 3 to rotate in the second direction, the first rack 22 and the second rack 23 drive the panel assembly 1 to move closer to the transmission gear 21, and the panel assembly 1 flips downward with the first connection point 101 as the center.

[0072] Furthermore, both the first rack 22 and the second rack 23 are connected to the panel assembly 1. The transmission gear 21 has teeth on both sides, namely the first external tooth 211 and the second external tooth 212. The first external tooth 211 and the second external tooth 212 are integrally set and separated by a cam. The first external tooth 211 and the second external tooth 212 drive the first rack 22 and the second rack 23 to move respectively. The first rack 22 and the second rack 23 move at different speeds. The first external tooth 211 drives the panel assembly 1 to move outward, and the second rack 23 drives the panel assembly 1 to rotate around the connection point between the first gear and the panel assembly 1 as the rotation center, so that the control panel 11 flips up. Under the action of the speed difference between the first rack 22 and the second rack 23, the panel assembly 1 synchronously completes the action of translating and flipping outward.

[0073] In some embodiments, the panel assembly 1 has an initial state and a flipped state, wherein when the panel assembly 1 is in the initial state, the first connection point 101 is higher than the third connection point 103.

[0074] In the above embodiment, under normal conditions, the first connection point 101 is located above the third connection point 103, so that when the first external tooth 211 and the second external tooth 212 drive the first rack 22 and the second rack 23 to move the panel assembly 1 away from the transmission gear 21, they can simultaneously flip upwards, thereby opening the opening of the entire housing.

[0075] In some embodiments, the first external tooth 211 and the second external tooth 212 have the same module, the number of teeth of the first external tooth 211 is z1, the number of teeth of the second external tooth 212 is z2, and z1 < z2; or, the first external tooth 211 and the second external tooth 212 have the same number of teeth, the module of the first external tooth 211 is m1, the module of the second external tooth 212 is m2, and m1 < m2.

[0076] In the above embodiments, by adopting a design where the number of teeth of the first external tooth 211 is less than the number of teeth of the second external tooth 212, or the module of the first external tooth 211 is less than the module of the second external tooth 212, the moving speed of the first rack 22 is less than the moving speed of the second rack 23, ensuring that the panel assembly 1 can rotate synchronously under the action of the speed difference between the first rack 22 and the second rack 23 during the translation process.

[0077] In the example of the first embodiment described above, the ratio of the number of teeth z2 of the second external tooth 212 to the number of teeth z1 of the first external tooth 211 is between 1 and 5, that is, 1 < z2 / z1 < 5, preferably 1.1 < z2 / z1 < 5.

[0078] In the example of the second embodiment of the above embodiment, the number of teeth on both sides of the gear is different. The ratio of the module m2 of the second external tooth 212 to the module m1 of the first external tooth 211 is between 1 and 5, that is, 1 < m2 / m1 < 5. Preferably, 1.1 < m2 / m1 < 5.

[0079] In some embodiments, the first rack 22 is hinged to the panel assembly 1, and the connecting rod 24 is hinged to the second rack 23 and the panel assembly 1 respectively.

[0080] In the above embodiments, the first rack 22 and the panel assembly 1, as well as the connecting rod 24 and the second rack 23 and the panel assembly 1, are all connected by hinges, which has high reliability and high flexibility. This can effectively prevent the panel assembly 1 from mechanically jamming during movement and flipping, and improve the flexibility and smoothness of the entire device's movement.

[0081] In some embodiments, the first rack 22 includes a base 221, a meshing transmission part 222, and a hinge connection part 223. The meshing transmission part 222 is fixedly disposed on the base 221. The hinge connection part 223 is fixedly disposed at one end of the base 221 near the panel assembly 1. A first hinge hole is provided at the end of the hinge connection part 223, and a second hinge hole is provided on the panel assembly 1. The first hinge hole and the second hinge hole are connected by a first hinge shaft.

[0082] In the above embodiment, the base 221, the meshing transmission part 222, and the hinge connection part 223 are an integral structure. The base 221 is a strip-shaped frame structure, the meshing transmission part 222 is a strip-shaped plate structure with several racks, the meshing transmission part 222 is fixedly installed on one side of the base 221, and the hinge connection part 223 is a connecting rod fixedly installed on the end of the base 221. One end of the connecting rod is integrally connected to the base 221, and the other end is provided with a first hinge hole. The panel assembly 1 and the first rack 22 are hinged through the first hinge shaft, and the reliability and flexibility of the connection are relatively high.

[0083] Specifically, the hinge connection part 223 is vertically arranged, while the base 221 and the meshing transmission part 222 are both horizontally arranged. The hinge connection part 223 includes two connecting rods spaced apart, and the ends of the two connecting rods are respectively provided with first hinge holes. The panel assembly 1 is provided with a hinge part, which includes two hinge plates arranged opposite each other. The two hinge plates are respectively provided with second hinge holes, which form a first connection point 101. The space between the two hinge plates can accommodate the installation space of the hinge connection part 223. The first rack 22 is provided with one end of the hinge connection part 223 extending into the space between the two hinge plates. The first hinge holes on the two connecting rods correspond to the second hinge holes on the two hinge plates and are connected by a first hinge shaft.

[0084] In some embodiments, reinforcing ribs are provided between the hinged connection 223 and the base 221, and between the hinged connection 223 and the base 221, to increase the structural strength of the first rack 22. Reinforcing ribs may also be provided on the second rack 23 to increase its own structural strength.

[0085] In some embodiments, the transmission assembly 2 further includes a transmission bracket 25, a first rack 22 and a second rack 23 are slidably connected to the transmission bracket 25, and a position switch 251 is provided on the transmission bracket 25; a trigger part 224 is provided on the first rack 22 or the second rack 23, and when the panel assembly 1 moves to a set position, the trigger part 224 triggers the position switch 251.

[0086] In the above embodiment, by setting the position switch 251 and the trigger part 224, when the panel assembly 1 moves to the set open position or closed position, a corresponding trigger signal can be issued, and the control device will stop driving, so that the panel assembly 1 is kept in the preset position or angle, avoiding mechanical damage caused by continued driving, and the controllability and safety are higher.

[0087] Specifically, the position switch 251 can be a micro switch or a position sensor. The position switch 251 is fixedly mounted on the transmission bracket 25, which is fixed inside the machine body. The trigger part 224 is a protrusion, which can be a protruding rod, a protruding bulge, a protruding block, or a protruding rib. Preferably, the trigger part 224 is integrally formed with the first rack 22, and the bottom wall of the first rack 22 protrudes downward to form the trigger part 224. More specifically, the bottom wall portion of the base 221 of the first rack 22 protrudes downward to form the trigger part 224.

[0088] In some embodiments, a trigger part 224 is provided on the first rack 22, and there are two position switches 251, including a first position switch 2511 and a second position switch 2512. The first position switch 2511 is used to detect whether the panel assembly 1 is fully opened, and the second position switch 2512 is used to detect whether the panel assembly 1 is fully closed. The two position switches 251 are spaced apart along the length direction of the transmission bracket 25. The first rack 22 and the second rack 23 are both slidably connected to the transmission bracket 25 along the length direction of the transmission bracket 25.

[0089] In some alternative embodiments, the first rack 22 is provided with two triggering parts 224, and the transmission bracket 25 is provided with a position switch 251. The triggering of the two triggering parts 224 and the position switch 251 respectively represent the signals of the lid being opened and the lid being closed.

[0090] In some alternative embodiments, the trigger 224 may also be disposed on the second rack 23.

[0091] In some embodiments, the transmission assembly 2 has two sets, which are distributed on both sides of the panel assembly 1.

[0092] In the above embodiments, by providing two sets of transmission components 2 on both sides of the panel assembly 1, it is possible to drive the panel assembly 1 to move and flip in a more balanced and stable manner from both sides.

[0093] Furthermore, the transmission bracket 25 is provided in two sets, and the two sets of transmission brackets 25 are respectively arranged on both sides of the panel assembly 1.

[0094] In some embodiments, the drive device further includes a transmission rod 4, which is connected between two transmission gears 21 of the two sets of transmission components 2. The drive component 3 is connected to the transmission rod 4 and is adapted to drive the transmission rod 4 to rotate so as to drive the two transmission gears 21 to rotate synchronously.

[0095] In the above embodiment, the transmission rod 4 set between the two transmission gears 21 facilitates the synchronous rotation of the two transmission gears 21 by a set of driving components 3, thereby ensuring the synchronous movement of the two sets of transmission components 2, making the synchronicity and consistency of the movement of the two sets of transmission components 2 higher, thus effectively ensuring the balance and stability of the panel assembly 1 during the movement process.

[0096] Specifically, the two ends of the transmission rod 4 are respectively interference-fitted into the inner holes of the two transmission gears 21 to achieve a fixed connection between the transmission rod 4 and the two transmission gears 21.

[0097] In some embodiments, the drive assembly 3 includes a drive motor 31, and a drive gear 32 is disposed on the output shaft of the drive motor 31; the drive assembly 3 also includes a reduction gear assembly, which includes a first reduction gear 33 and a second reduction gear 34. The first reduction gear 33 meshes with the drive gear 32, and the second reduction gear 34 is driven between the first reduction gear 33 and the transmission gear 21. The reduction gear assembly enables the high speed of the output shaft of the drive motor 31 to be reduced to a set speed range, ensuring that the panel assembly 1 can open and close smoothly.

[0098] In some preferred embodiments, a first reduction gear 33 and a second reduction gear 34 are connected. The first reduction gear 33 meshes between the drive gear 32 and the second reduction gear 34. The second reduction gear 34 is mounted on the transmission rod 4 and engages with the transmission rod 4 in the circumferential direction.

[0099] In the above embodiment, the second reduction gear 34 is mounted on the transmission rod 4 and engages with the transmission rod 4 in the circumferential direction, thereby enabling the synchronous driving of two sets of transmission gears 21 by the same drive motor 31, saving driving costs, and improving the consistency and synchronicity of the movement of the two sets of transmission gears 21.

[0100] Furthermore, the first reduction gear 33 has a third external tooth 331 and a fourth external tooth 332 coaxially arranged. The third external tooth 331 meshes with the drive gear 32, and the fourth external tooth 332 meshes with the second reduction gear 34. The second reduction gear 34 is sleeved on the transmission rod 4, and the two are in upper limit engagement in the circumferential direction to ensure that they can rotate synchronously. In a specific example, the outer circumferential cross-sectional shape of the transmission rod 4 is hexagonal, and the inner cross-sectional shape of the second reduction gear 34 is also hexagonal to achieve synchronous rotation. Preferably, the second reduction gear 34 is located at the middle position of the transmission rod 4.

[0101] Of course, in other alternative embodiments, the cross-sectional shape of the outer periphery of the transmission rod 4 and the inner hole cross-section of the second reduction gear 34 can also be set as a quadrilateral, a triangle, etc. Alternatively, a key can be set in one of the outer periphery of the transmission rod 4 and the inner hole of the second reduction gear 34, and a keyway can be set in the other, so that the circumferential connection can be achieved through the key and the keyway.

[0102] In some alternative implementations, the transmission rod 4 can be omitted, and the transmission components 2 on both sides can be driven by two sets of drive components 3 respectively.

[0103] Furthermore, the drive assembly 3 also includes a motor bracket 35, which is fixedly installed in the body. The drive motor 31 is mounted on the motor bracket 35, and the first reduction gear 33 is rotatably connected to the motor bracket 35. Preferably, the motor bracket 35 is provided with a through hole through which the transmission rod 4 can pass. The transmission rod 4 can rotate freely in the through hole. This arrangement can improve the compactness of the drive device structure, and the motor bracket 35 can also provide a certain support and limiting effect for the transmission rod 4.

[0104] Furthermore, the transmission bracket 25 includes a bracket body and two mounting plates disposed on opposite sides of the bracket body. An installation space for accommodating the transmission rack is formed between the two mounting plates. Preferably, the two mounting plates extend upward by a predetermined length corresponding to the position of the transmission gear 21 to form an extension protrusion 252. The two extension protrusions 252 form an installation space for installing the transmission gear 21. The transmission gear 21 is placed in the installation space formed between the two extension protrusions 252. The two extension protrusions 252 are respectively provided with connecting holes, and the transmission rod 4 is rotatably connected to the connecting holes of the two extension protrusions 252.

[0105] In some alternative implementations, the speed reduction gear assembly can be mounted together with the drive motor 31, hidden inside the drive motor 31, and output after speed reduction.

[0106] In some alternative implementations, the motor bracket 35 can be omitted, and both the drive motor 31 and the first speed reduction gear can be mounted on the transmission bracket 25.

[0107] In some alternative implementations, the panel translation and flipping device in this embodiment can also be changed to manual, and the panel assembly 1 can be opened or closed by hand.

[0108] According to an embodiment of the present invention, another aspect provides a cooking device, including a housing, a water tank 5, and a panel translation and flipping device according to any of the above embodiments. The housing has an opening on one side; the water tank 5 is disposed inside the housing and located at the opening; the panel assembly 1 is disposed at the opening; and a driving device is disposed inside the housing. The driving device is adapted to drive the panel assembly 1 to flip to open or close the opening.

[0109] Preferably, the cooking device is a microwave oven or an oven. More preferably, the cooking device is a microwave oven or an oven with steam baking, steam cooking, or steam humidification functions.

[0110] The panel sliding and flipping assembly provided in this embodiment includes a drive motor 31, a motor bracket 35, a drive gear 32, a speed reduction gear assembly, a transmission gear 21, a first rack 22, a second rack 23, a panel assembly 1, a position switch 251, a transmission rod 4, a transmission bracket 25, a connecting rod 24, and a water tank 5. The drive motor 31 is mounted on the motor bracket 35 after being fitted with the drive gear 32. The speed reduction gear assembly includes a first reduction gear 33 rotatably mounted on the motor bracket 35, and the drive gear 32 and the first reduction gear 33 are connected by a third external tooth 331. The speed reduction gear assembly also includes a second reduction gear 34 mounted on the transmission rod 4, and the second reduction gear 34 meshes with the fourth external tooth 332 of the first reduction gear 33.

[0111] Furthermore, the transmission gear 21, the first rack 22, the second rack 23, and the position switch 251 are all mounted on the transmission bracket 25. The first external tooth 211 and the second external tooth 212 on the transmission gear 21 are respectively connected to the first rack 22 and the second rack 23 through tooth meshing. The first hinge hole on the first rack 22 is movably connected to the first connection point 101 of the panel assembly 1. The two ends of the connecting rod 24 are movably connected to the second connection point 102 of the second rack 23 and the third connection point 103 of the panel assembly 1. The water tank 5 is placed behind the panel assembly 1. The ratio of the number of teeth of the second external tooth 212 to the number of teeth of the first external tooth 211 is between 1 and 5, with 1.1 to 1.5 being optimal. The number of gear pairs in the speed reduction gear assembly can be 1 to 3. The drive motor 31 drives the transmission gear 21 to rotate through the drive gear 32 and the speed reduction gear assembly. The first external tooth 211 and the second external tooth 212 on the transmission gear 21 drive the first rack 22 and the second rack 23 to move, respectively. The first rack 22 drives the panel assembly 1 to move outward, and the second rack 23 drives the panel assembly 1 to move outward through the connecting rod 24. Because the speed of the second rack 23 is greater than that of the first rack 22, the panel assembly 1 will rotate around the first connection point 101. The panel assembly 1 can be moved outward and flipped to facilitate the removal of the water tank 5 hidden behind the panel assembly 1. It also makes it easy to remove the control panel 11 of the panel assembly 1 for replacement, rework or repair of the components inside the panel assembly 1. When the first rack 22 moves to the set position, the trigger part 224 of the first rack 22 triggers the first position switch 2511, and the motor stops working. Conversely, when the drive point of the first rack 22 triggers the second position switch 2512, the motor stops working and the panel assembly 1 is closed. The panel assembly 1 can also be opened and closed by pushing and pulling by hand, and the water tank 5 can be removed and placed, and the panel assembly 1 can be disassembled and repaired.

[0112] This application, while ensuring the consistency of product appearance, allows for the removal and replacement of the water tank 5 hidden behind the panel assembly 1 by shifting and flipping the panel assembly 1. This also facilitates the rework and repair of the panel assembly 1, solving the problems of inconvenience in removing and placing the hidden water tank 5 and inconvenience in reworking and repairing the control panel 11, thereby improving the product's market competitiveness.

[0113] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
