[0002] For air conditioners with fresh air function, the main fan wheel and the fresh air wheel are usually driven by corresponding motors to realize the circulation and regulation of the indoor air conditioner. However, this not only increases the number of parts and the size and weight of the whole unit, but also the existing transmission methods often use mechanical connections, such as belt drive or gear drive. These transmission methods will generate large vibrations and friction during operation, resulting in noise generation and energy loss. Utility Model Content

[0003] The main purpose of this utility model is to propose an air conditioner that aims to improve the energy efficiency of the air conditioner, while also achieving flexible control of the rotation of the main fan wheel and the fresh fan wheel.

[0004] To achieve the above objectives, the air conditioner proposed in this utility model includes:

[0005] The housing contains the main impeller;

[0006] A fresh air module is connected to the housing, and the fresh air module includes a fresh air impeller;

[0007] The drive motor and transmission assembly include a magnetically coupled drive wheel, a first driven wheel, and a second driven wheel. The drive wheel is driven by the drive motor, the first driven wheel is driven by the main wind turbine, and the second driven wheel is driven by the fresh wind turbine.

[0008] A first clutch, driven and connected to the first driven wheel, is used to cause relative movement between the driving wheel and the first driven wheel, resulting in a engaged position and a stopped position; and

[0009] The second clutch is driven and connected to the second driven wheel, and is used to make the driving wheel and the second driven wheel move relative to each other to have a linkage position and a stop position.

[0010] In one embodiment, the first driven wheel is disposed on the periphery of the driving wheel, and a coupling gap is formed between the two outer peripheral surfaces of the driving wheel and the first driven wheel that are coupled together.

[0013] In one embodiment, the end of the driving wheel away from the drive motor is provided with a groove for the second driven wheel to be inserted, and a coupling gap is formed between the two surfaces of the driving wheel and the second driven wheel that are coupled together.

[0014] In one embodiment, the first driven wheel is disposed on the end side of the driving wheel, and a coupling gap is formed between the two surfaces of the driving wheel and the first driven wheel that are coupled together.

[0015] In one embodiment, the second driven wheel is disposed on the periphery of the driving wheel, and a coupling gap is formed between the two outer peripheral surfaces of the driving wheel and the second driven wheel that are coupled together.

[0016] In one embodiment, the fresh air module includes a fresh air housing, and the drive motor is disposed inside the fresh air housing and arranged at intervals from the fresh air impeller.

[0017] In one embodiment, the diameters of the first driven wheel and the second driven wheel are both smaller than the diameter of the driving wheel.

[0018] In one embodiment, the driving wheel, the first driven wheel, and the second driven wheel are all magnetic wheels, and the coupling gap L formed between the driving wheel and the first driven wheel, and between the driving wheel and the second driven wheel, all satisfy: 0.1mm≤L≤2mm.

[0021] In one embodiment, both the first clutch and the second clutch are electromagnetic clutches.

[0022] In the technical solution of this utility model, the drive motor is driven and connected to the active wheel. The power of the drive motor is transmitted to the main fan and the fresh fan through the magnetic force between the active wheel and the first driven wheel, and between the active wheel and the second driven wheel. On the one hand, there is no need to equip an additional drive motor to drive the fresh fan, saving the installation space required for the drive motor and helping to achieve a compact layout of various components in the air conditioner. At the same time, the drive motor can drive the main fan and the fresh fan to rotate simultaneously. On the other hand, the transmission component includes an active wheel and a driven wheel with magnetic coupling transmission. The power of the drive motor can be transmitted through the magnetic force between the active wheel and the driven wheel. Compared with traditional mechanical transmission, there is no need for direct contact between the active wheel and the driven wheel, which effectively avoids friction between the active wheel and the driven wheel during operation, reduces the operating noise and energy loss of the air conditioner, thereby improving the overall energy efficiency of the air conditioner. It can also, to a certain extent, ensure the service life and high-precision transmission of the transmission component.

[0023] By connecting the first clutch to the first driven wheel and the second clutch to the second driven wheel, the power transmission between the drive motor and the first and / or second driven wheels can be effectively released under the action of the first and / or second clutches.

[0039] For air conditioners with fresh air function, the main fan wheel and the fresh air wheel are usually driven by corresponding motors to realize the circulation and regulation of the indoor air conditioner. However, this not only increases the number of parts and the size and weight of the whole unit, but also the existing transmission methods often use mechanical connections, such as belt drive or gear drive. These transmission methods will generate large vibrations and friction during operation, resulting in noise generation and energy loss.

[0040] To solve this technical problem, this utility model proposes an air conditioner.

[0041] Please see Figures 1 to 5 In one embodiment of this utility model, the air conditioner includes a housing 13, a fresh air module 20, a drive motor 12, a transmission assembly 30, a first clutch 41, and a second clutch 42. The housing 13 houses a main fan wheel 11. The fresh air module 20 is connected to the housing 13 and includes a fresh air wheel 21. The transmission assembly 30 includes a magnetically coupled drive wheel 31, a first driven wheel 321, and a second driven wheel 322. The drive wheel 31 is driven by the drive motor 12, and the first driven wheel 321 is connected to the main fan wheel 11. 1. A transmission connection is established, wherein the second driven wheel 322 is drivenly connected to the fresh air wheel 21; a first clutch 41 is drivenly connected to the first driven wheel 321, used to enable the driving wheel 31 and the first driven wheel 321 to move relative to each other to have a linkage position and a stop position; a second clutch 42 is drivenly connected to the second driven wheel 322, used to enable the driving wheel 31 and the second driven wheel 322 to move relative to each other to have a linkage position and a stop position; this configuration improves the energy efficiency of the air conditioner, and at the same time, enables flexible control of the rotation of the main fan wheel 11 and the fresh air wheel 21.

[0042] In the technical solution of this utility model, the drive motor 12 is driven and connected to the drive wheel 31. Through the magnetic field force between the drive wheel 31 and the first driven wheel 321, and between the drive wheel 31 and the second driven wheel 322, the power of the drive motor 12 is transmitted to the main fan wheel 11 and the fresh fan wheel 21. On the one hand, there is no need to equip an additional drive motor 12 to drive the fresh fan wheel 21 separately, saving the installation space required for the drive motor 12 and helping to achieve a compact layout of various components in the air conditioner. At the same time, the drive motor 12 can drive the main fan wheel 11 and the fresh fan wheel 21 to rotate simultaneously. On the other hand, the transmission component 30 includes the drive wheel 31 and the driven wheel with magnetic coupling transmission. Through the magnetic field force between the drive wheel 31 and the driven wheel, the power of the drive motor 12 can be transmitted. Compared with the traditional mechanical transmission, the drive wheel 31 and the driven wheel do not need to be in direct contact, effectively avoiding friction between the drive wheel 31 and the driven wheel during operation, reducing the operating noise and energy loss of the air conditioner, thereby improving the overall energy efficiency of the air conditioner, and also ensuring the service life and high-precision transmission of the transmission component 30 to a certain extent.

[0043] By connecting the first clutch 41 to the first driven wheel 321 and the second clutch 42 to the second driven wheel 322, the power transmission between the drive motor 12 and the first driven wheel 321 and / or the second driven wheel 322 can be effectively released under the action of the first clutch 41 and / or the second clutch 42. This enables the stop control of the main fan wheel 11 and / or the fresh fan wheel 21, and allows for flexible control of the rotation of the main fan wheel 11 and the fresh fan wheel 21, while also meeting the user's usage needs.

[0044] It should be noted that the air conditioner can be configured as an indoor unit of a split-type air conditioner, which can be a wall-mounted indoor unit or a floor-standing indoor unit; the air conditioner can also be configured as a packaged air conditioner.

[0045] The driving wheel 31 and the first driven wheel 321, as well as the driving wheel 31 and the second driven wheel 322, are all driven by magnetic coupling. It is understood that the driving wheel 31, the first driven wheel 321, and the second driven wheel 322 are all equipped with magnetic structures, such as permanent magnets with at least multiple different magnetic poles, so that the interaction force between the magnetic poles can be used to complete the power transmission between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322. The transmission assembly 30 is located on the side of the main fan 11 facing the fresh fan 21, which facilitates the efficient use of the installation space near the fresh fan 21, helping to reduce the size of the air conditioner and achieve miniaturization.

[0046] Specifically, the air conditioner includes a casing 13, which includes at least a chassis and a front frame. The chassis can be used to install the main fan 11 and the fresh air module 20, so that the air conditioner has a main fan 11 and a fresh air wheel 21. When the main fan 11 rotates, it can drive airflow into the air conditioner. After air treatment such as heat exchange or dehumidification, the airflow is sent into the room to achieve indoor air conditioning. The fresh air casing of the fresh air module 20 can be connected to the casing 13 to complete the assembly of the fresh air module 20 in the air conditioner, ensuring that the air conditioner has a fresh air function. The fresh air module 20 is provided with a fresh air duct and a fresh air wheel 21 located in the fresh air duct. The fresh air duct is connected to the outside through the fresh air pipe and has a fresh air vent connected to the room. When the fresh air wheel 21 rotates, it can drive outdoor air into the fresh air duct and send it into the room through the fresh air vent to achieve indoor air renewal and improve indoor air freshness.

[0047] The first clutch 41 or the second clutch 42 can be installed using screw connections, snap-fit ​​connections, or other connection methods. Their installation locations include, but are not limited to, the fresh air housing and the unit housing 13 of the fresh air module 20. To disengage the power transmission between the drive wheel 31 and the fresh air wheel 21, since the drive wheel 31 is connected to the first driven wheel 321 and the second driven wheel 322, the first clutch 41 is driven by the first driven wheel 321, and the second clutch 42 is driven by the second driven wheel 322. Therefore, under the action of the first clutch 41, the first driven wheel 321 moves relative to the drive wheel 31, switching between a driven position and a stopped position. When the first driven wheel 321 is in the stopped position, its position can be adjusted to allow it to interact with the drive wheel 31. The position ensures that the magnetic field force between the driving wheel 31 and the first driven wheel 321 is invalidated, and the power of the drive motor 12 cannot be transmitted to the first driven wheel 321 and the main impeller 11. That is, under the driving action of the drive motor 12, the main impeller 11 cannot rotate. Under the action of the second clutch 42, the second driven wheel 322 moves relative to the driving wheel 31, switching between the linkage position and the stop position. When the second driven wheel 322 is in the stop position, the position of the second driven wheel 322 can be made to exceed the position where it can interact with the driving wheel 31, ensuring that the magnetic field force between the driving wheel 31 and the second driven wheel 322 is invalidated, and the power of the drive motor 12 cannot be transmitted to the second driven wheel 322 and the new impeller 21. That is, under the driving action of the drive motor 12, the new impeller 21 cannot rotate.

[0048] Optionally, in an embodiment of this utility model, the first driven wheel 321 is disposed on the periphery of the driving wheel 31, and a coupling gap 33 is formed between the two outer peripheral surfaces of the driving wheel 31 and the first driven wheel 321 that are coupled together. It can be understood that, since the first driven wheel 321 is disposed on the periphery of the driving wheel 31, the two surfaces of the driving wheel 31 and the first driven wheel 321 that are coupled together are the outer peripheral surface of the driving wheel 31 and the outer peripheral surface of the first driven wheel 321, respectively. Furthermore, to avoid wear and noise caused by mechanical friction between the driving wheel 31 and the first driven wheel 321, a certain coupling gap 33 is left between the outer peripheral surfaces of the driving wheel 31 and the first driven wheel 321 while ensuring the transmission effect between them.

[0049] like Figures 2 to 5 As shown, the first driven wheel 321 is connected to the main fan wheel 11 via the first rotating shaft, and the driving wheel 31 is connected to the drive shaft of the drive motor 12. Depending on the positional relationship between the drive motor 12 and the main fan wheel 11, the driving wheel 31 can be located above, below, or behind the first driven wheel 321. Then, by utilizing the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the first driven wheel 321, the power of the drive motor 12 is transmitted sequentially to the first driven wheel 321 and the main fan wheel 11 via the driving wheel 31, so that the main fan wheel 11 rotates together with the first driven wheel 321 and drives the airflow into the air conditioner. At the same time, it ensures that the air conditioner maintains low noise and low wear during operation.

[0050] Optionally, in one embodiment of this utility model, the second driven wheel 322 is disposed on the periphery of the driving wheel 31, and a coupling gap 33 is formed between the two outer peripheral surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together. It can be understood that, since the second driven wheel 322 is disposed on the periphery of the driving wheel 31, the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together are the outer peripheral surface of the driving wheel 31 and the outer peripheral surface of the driven wheel 322, respectively. Furthermore, to avoid wear and noise caused by mechanical friction between the driving wheel 31 and the second driven wheel 322, a certain coupling gap 33 is left between the outer peripheral surfaces of the driving wheel 31 and the second driven wheel 322 while ensuring the transmission effect between them.

[0051] like Figures 2 to 5As shown, the second driven wheel 322 is connected to the fresh air wheel 21 via the second rotating shaft, and the driving wheel 31 is connected to the drive shaft of the drive motor 12. Depending on the positional relationship between the drive motor 12 and the fresh air wheel 21, the driving wheel 31 can be located above, below, or behind the second driven wheel 322. Then, by utilizing the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the second driven wheel 322, the power of the drive motor 12 is transmitted sequentially to the second driven wheel 322 and the fresh air wheel 21 via the driving wheel 31, so that the fresh air wheel 21 rotates together with the second driven wheel 322 and drives the airflow into the air conditioner. At the same time, it ensures that the air conditioner maintains low noise and low wear during operation. Specifically, in this embodiment, the driving wheel 31 is spaced between the first driven wheel 321 and the second driven wheel 322. However, this design is not limited to this. In other embodiments, without interfering with the rotation of the first driven wheel 321 and the second driven wheel 322, the first driven wheel 321 and the second driven wheel 322 can be arranged on the same side of the driving wheel 31.

[0052] Optionally, in another embodiment of this utility model, the driving wheel 31 is located between the drive motor 12 and the second driven wheel 322, and a coupling gap 33 is formed between the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together. It is understood that the second driven wheel 322 is located along the axial extension direction of the driving wheel 31. In this case, the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together are the end face of the driving wheel 31 and the end face of the second driven wheel 322, respectively. The axes of the driving wheel 31 and the second driven wheel 322 may coincide or be staggered; this is not limited here. To avoid wear and noise caused by mechanical friction between the driving wheel 31 and the second driven wheel 322, a certain coupling gap 33 is left between the end face of the driving wheel 31 and the end face of the second driven wheel 322, while ensuring the transmission effect between the driving wheel 31 and the second driven wheel 322.

[0053] Specifically, the driving wheel 31 is connected to the drive shaft of the drive motor 12, and the second driven wheel 322 is connected to the fresh air wheel 21 through the second rotating shaft, or the second driven wheel 322 is fixed to the center of the fresh air wheel 21 by embedding. According to the positional relationship between the drive motor 12 and the fresh air wheel 21, the power of the drive motor 12 is transmitted to the second driven wheel 322 and the fresh air wheel 21 in sequence through the driving wheel 31 by the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the second driven wheel 322, so that the fresh air wheel 21 rotates together with the second driven wheel 322 and drives the airflow into the air conditioner. At the same time, it ensures that the air conditioner maintains low noise and low wear during operation.

[0054] Optionally, in another embodiment of this utility model, the end of the driving wheel 31 facing away from the drive motor 12 is provided with a groove for the second driven wheel 322 to be inserted, and a coupling gap 33 is formed between the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together. It can be understood that since the second driven wheel 322 is located in the groove of the driving wheel 31, the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together are the inner circumferential surface of the driving wheel 31 and the outer circumferential surface of the second driven wheel 322, respectively. The axes of the driving wheel 31 and the second driven wheel 322 may coincide or be offset; this is not limited here. To avoid wear and noise caused by mechanical friction between the driving wheel 31 and the second driven wheel 322, a certain coupling gap 33 is left between the inner circumferential surface of the driving wheel 31 and the outer circumferential surface of the second driven wheel 322, while ensuring the transmission effect between the driving wheel 31 and the second driven wheel 322.

[0055] Specifically, the driving wheel 31 is connected to the drive shaft of the drive motor 12, and the second driven wheel 322 is connected to the fresh air wheel 21 via a second rotating shaft. Based on the positional relationship between the drive motor 12 and the fresh air wheel 21, the magnetic interaction force (attraction or repulsion) between the driving wheel 31 and the second driven wheel 322 transmits the power of the drive motor 12 sequentially to the second driven wheel 322 and the fresh air wheel 21 via the driving wheel 31. This causes the fresh air wheel 21 to rotate together with the second driven wheel 322, driving airflow into the air conditioner. Simultaneously, this ensures that the air conditioner maintains low noise and low wear during operation. However, this design is not limited to this; in other embodiments, the driving wheel 31 is connected to the second driven wheel 322 via a third driven wheel.

[0056] Optionally, in an embodiment of this utility model, the first driven wheel 321 is disposed on the end side of the driving wheel 31, and a coupling gap 33 is formed between the two surfaces of the driving wheel 31 and the first driven wheel 321 that are coupled together. It can be understood that the first driven wheel 321 is disposed in the direction extending along the axis of the driving wheel 31. In this case, the two surfaces of the driving wheel 31 and the first driven wheel 321 that are coupled together are the end face of the driving wheel 31 and the end face of the first driven wheel 321, respectively. The axes of the driving wheel 31 and the first driven wheel 321 may coincide or be offset; this is not limited here. To avoid wear and noise caused by mechanical friction between the driving wheel 31 and the first driven wheel 321, a certain coupling gap 33 is left between the end faces of the driving wheel 31 and the first driven wheel 321, while ensuring the transmission effect between them.

[0057] Specifically, the drive wheel 31 is connected to the drive shaft of the drive motor 12, and the first driven wheel 321 is connected to the main fan wheel 11 through the first rotating shaft, or the first driven wheel 321 is fixed to the center of the main fan wheel 11 by embedding. According to the positional relationship between the drive motor 12 and the main fan wheel 11, the power of the drive motor 12 is transmitted to the first driven wheel 321 and the main fan wheel 11 in sequence through the drive wheel 31 by the magnetic pole interaction force (attraction or repulsion) between the drive wheel 31 and the first driven wheel 321, so that the main fan wheel 11 rotates together with the first driven wheel 321 and drives the airflow into the air conditioner. At the same time, it ensures that the air conditioner maintains low noise and low wear during operation.

[0058] Optionally, in an embodiment of this utility model, the second driven wheel 322 is disposed on the periphery of the driving wheel 31, and a coupling gap 33 is formed between the two outer peripheral surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together. It can be understood that, since the second driven wheel 322 is disposed on the periphery of the driving wheel 31, the two surfaces of the driving wheel 31 and the second driven wheel 322 that are coupled together are the outer peripheral surface of the driving wheel 31 and the outer peripheral surface of the driven wheel 322, respectively. Furthermore, to avoid wear and noise caused by mechanical friction between the driving wheel 31 and the second driven wheel 322, a certain coupling gap 33 is left between the outer peripheral surfaces of the driving wheel 31 and the second driven wheel 322, while ensuring the transmission effect between them.

[0059] Specifically, the second driven wheel 322 is connected to the fresh air wheel 21 via a second rotating shaft, and the driving wheel 31 is connected to the drive shaft of the drive motor 12. Depending on the positional relationship between the drive motor 12 and the fresh air wheel 21, the driving wheel 31 can be located above, below, or behind the second driven wheel 322. Then, utilizing the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the second driven wheel 322, the power of the drive motor 12 is transmitted sequentially from the driving wheel 31 to the second driven wheel 322 and the fresh air wheel 21, causing the fresh air wheel 21 to rotate together with the second driven wheel 322, driving airflow into the air conditioner. Simultaneously, this ensures that the air conditioner maintains low noise and low wear during operation. However, this design is not limited to this; in other embodiments, the driving wheel 31 is connected to the second driven wheel 322 via a third driven wheel.

[0060] Optionally, in an embodiment of this utility model, the fresh air module 20 includes a fresh air housing, and the drive motor 12 is disposed inside the fresh air housing and arranged at intervals from the fresh air impeller 21. It can be understood that both the fresh air impeller 21 and the drive motor 12 are disposed inside the fresh air housing of the fresh air module 20, making full use of the internal space of the fresh air housing, saving the space occupied by the drive motor 12 on the housing 13, thereby improving the compactness of the fresh air module 20 and the main impeller 11, and helping to shorten the axial dimension of the air conditioner on the main impeller 11 and reduce the volume of the air conditioner.

[0061] With the first driven wheel 321 and the arrangement on the end side of the driving wheel 31, in order to ensure the transmission effect between the driving wheel 31 and the first driven wheel 321, in one embodiment, the driving wheel 31 can be arranged inside the fresh air wheel 21 along with the drive motor 12; in another embodiment, the driving wheel 31 is arranged outside the fresh air casing.

[0062] Optionally, in an embodiment of this utility model, the diameters of the first driven wheel 321 and the second driven wheel 322 are both smaller than the diameter of the driving wheel 31. It is understood that, with the different positional relationships of the driving wheel 31, the first driven wheel 321, and the second driven wheel 322, by limiting the diameters of the first driven wheel 321 and the second driven wheel 322 to be smaller than the diameter of the second driven wheel 322, differential transmission can be achieved between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322. This helps reduce the power consumption of the drive motor 12 while meeting air handling requirements, such as the fresh air impeller 21 rotating at a higher speed than the main air impeller 11, effectively ensuring the freshness of indoor air. However, this design is not limited to this; in other embodiments, the diameter of the first driven wheel 321 is greater than or equal to the diameter of the driving wheel 31.

[0063] Optionally, in an embodiment of this utility model, the driving wheel 31, the first driven wheel 321, and the second driven wheel 322 are all magnetic wheels. The coupling gaps 33L formed between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322, all satisfy: 0.1mm≤L≤2mm. With this setting, while designing the positional relationship between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322, the coupling gaps 33 between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322 are reasonably designed. This ensures reliable power transmission between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322. At the same time, it effectively reduces noise and wear caused by mechanical contact between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322, improves the service life of the transmission component 30, and improves the overall energy efficiency of the air conditioner, while reducing maintenance costs.

[0064] The specific values ​​of the coupling gap 33 between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322, include, but are not limited to, 0.1mm, 0.2mm, 0.4mm, 0.5mm, 0.6mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 1.9mm, and 2mm. However, in other embodiments, under the condition of meeting noise reduction and transmission requirements, the coupling gap 33 between the driving wheel 31 and the first driven wheel 321, and between the driving wheel 31 and the second driven wheel 322, can be greater than 2mm or less than 0.1mm.

[0065] Optionally, in an embodiment of this utility model, both the first clutch 41 and the second clutch 42 are electromagnetic clutches, which helps to reduce the operating noise of the first clutch 41 and the second clutch 42. It is understood that when neither the first clutch 41 nor the second clutch 42 is energized, the two surfaces of the driving wheel 31 coupled with the first driven wheel 321 are arranged facing each other, and the two surfaces of the driving wheel 31 coupled with the second driven wheel 322 are arranged facing each other.

[0066] The first clutch 41 is disposed between the main impeller 11 and the first driven wheel 321; or the first clutch 41 is disposed on the side of the first driven wheel 321 away from the main impeller 11; furthermore, in one embodiment, such as Figures 2 to 5 As shown, when the first driven wheel 321 is connected to the main impeller 11 through the first rotating shaft, the first clutch 41 can be in the form of a ring structure and fitted onto the first rotating shaft. Then, when the first clutch 41 is energized, the first clutch 41 generates electromagnetic force and attracts the first driven wheel 321 from the linkage position to the stop position. At this time, the first driven wheel 321 and the first clutch 41 are in contact, and the gap between the first driven wheel 321 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the first driven wheel 321 and the driving wheel 31 is invalid, and the power of the drive motor 12 cannot be transmitted to the first driven wheel 321 and the main impeller 11.

[0067] In another embodiment, the first clutch 41 is fixed to the housing 13 and has a push rod extending toward the first driven wheel 321. When the first clutch 41 is energized, the electromagnetic force generated by the first clutch 41 pushes the push rod to abut against the first driven wheel 321 and pushes the first driven wheel 321 from the linkage position to the stop position by the applied thrust. At this time, the gap between the first driven wheel 321 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the first driven wheel 321 and the driving wheel 31 fails, and the power of the drive motor 12 cannot be transmitted to the first driven wheel 321 and the main impeller 11.

[0068] The second clutch 42 is disposed between the fresh air impeller 21 and the second driven wheel 322; or the second clutch 42 is disposed on the side of the second driven wheel 322 away from the fresh air impeller 21; furthermore, in one embodiment, such as Figures 2 to 5 As shown, when the second driven wheel 322 is connected to the fresh air wheel 21 through the second rotating shaft, the second clutch 42 can be in the form of a ring structure and fitted onto the second rotating shaft. Then, when the second clutch 42 is energized, the second clutch 42 generates electromagnetic force and attracts the second driven wheel 322 from the linkage position to the stop position. At this time, the second driven wheel 322 and the second clutch 42 are in contact, and the gap between the second driven wheel 322 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the second driven wheel 322 and the driving wheel 31 is invalid, and the power of the drive motor 12 cannot be transmitted to the second driven wheel 322 and the fresh air wheel 21.

[0069] In another embodiment, the second clutch 42 is fixed to the housing 13 or the fresh air housing and has a push rod extending toward the second driven wheel 322. When the second clutch 42 is energized, the electromagnetic force generated by the second clutch 42 pushes the push rod to abut against the second driven wheel 322, and through the applied thrust, pushes the second driven wheel 322 from the engaged position to the stopped position. At this time, the gap between the second driven wheel 322 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the second driven wheel 322 and the driving wheel 31 is ineffective, and the power of the drive motor 12 cannot be transmitted to the second driven wheel 322 and the fresh air wheel 21. However, this design is not limited to this. In other embodiments, the first clutch 41 and / or the second clutch 42 are configured as mechanical clutches, which can also move the first driven wheel 321 and / or the second driven wheel 322 from the engaged position to the stopped position.

[0070] In addition, in order to ensure the synchronous rotation of the first driven wheel 321, the second driven wheel 322 and the driving wheel 31, the air conditioner also includes a reset structure. The reset structure can be located in the corresponding clutch or installed on the fresh air casing or the housing 13, so as to move the first driven wheel 321 and the second driven wheel 322 from the stop position to the linkage position.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
