[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. Summary of the Invention

[0003] The main objective of this invention is to propose an air conditioner that aims to improve the overall energy efficiency of the air conditioner.

[0004] To achieve the above objectives, the present invention provides an air conditioner comprising:

[0005] The housing contains the main impeller;

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

[0007] A drive motor, located between the main wind turbine and the new wind turbine, has a first drive shaft and a second drive shaft, respectively used to drive the main wind turbine and the new wind turbine; and

[0008] At least one set of transmission components, each set of transmission components including a driving wheel and a driven wheel with magnetic coupling transmission, wherein one of the main wind turbine and the new wind turbine is connected to the drive motor through the transmission components.

[0009] In one embodiment, the first drive shaft is connected to the main wind turbine via the transmission assembly, and the second drive shaft is connected to the new wind turbine.

[0010] In one embodiment, the transmission assembly is provided in two sets, one of which is connected to the first drive shaft and the main impeller, and the other is connected to the second drive shaft and the new impeller.

[0011] In one embodiment, the first drive shaft is driven to the main wind turbine, and the second drive shaft is driven to the new wind turbine through the transmission assembly.

[0012] In one embodiment, the driven wheel has a smaller diameter than the driving wheel, and the driven wheel is connected to the new air impeller via a drive mechanism.

[0013] In one embodiment, both the driving wheel and the driven wheel are magnetic wheels, and the coupling gap L formed between the driving wheel and the driven wheel satisfies: 0.1mm≤L≤2mm.

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

[0015] Alternatively, the driven wheel is located at the end of the driving wheel, and a coupling gap is formed between the two surfaces of the driving wheel and the driven wheel that are coupled together;

[0016] Alternatively, the driving wheel may have a groove for the driven wheel to be inserted into, and a coupling gap may be formed between the two surfaces of the driving wheel and the driven wheel that are coupled together.

[0017] In one embodiment, the air conditioner further includes a clutch that is drivenly connected to the driven wheel, the clutch being used to cause the driving wheel and the driven wheel to move relative to each other to have a driven position and a stopped position;

[0018] Driven by the drive motor, at the linkage position, the main impeller and the new impeller rotate synchronously through magnetic coupling, and at the stop position, the new impeller or the main impeller stops rotating.

[0020] In one embodiment, the clutch is located between the fresh impeller and the driven impeller; or the clutch is located on the side of the driven impeller away from the fresh impeller.

[0021] In one embodiment, the clutch is located between the main impeller and the driven impeller; or the clutch is located on the side of the driven impeller away from the main impeller.

[0022] In the technical solution of this invention, a drive motor is connected to one of the main fan wheel and the fresh fan wheel through a set of transmission components. The power of the drive motor is then transmitted through the transmission components, driving one of the main fan wheel and the fresh fan wheel to rotate. Furthermore, the drive motor is also connected to the other of the main fan wheel and the fresh fan wheel, driving the other of the main fan wheel and the fresh fan wheel to rotate. On the one hand, there is no need to equip a separate drive motor for the fresh fan wheel, saving the installation space required for the drive motor and contributing to a compact layout of the components within the air conditioner. Simultaneously, the drive motor can drive both the main fan wheel and the fresh fan wheel to rotate. On the other hand, the transmission components include a magnetically coupled drive wheel and a driven wheel. Through the magnetic field force between the drive wheel and the driven wheel, the power of the drive motor can be transmitted. Compared to traditional mechanical transmission, the drive wheel and the driven wheel do not need to be in direct contact, effectively avoiding friction between them during operation, reducing 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 components. Attached Figure Description

[0037] 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.

[0038] To address this technical problem, the present invention proposes an air conditioner.

[0039] Please see Figures 1 to 4In one embodiment of the present invention, the air conditioner includes a housing 13, a fresh air module 20, a drive motor 12, and at least one set of transmission components 30. The housing 13 is provided with a main fan 11. The fresh air module 20 is installed in the housing 13 and includes a fresh air wheel 21. The drive motor 12 is located between the main fan 11 and the fresh air wheel 21. The drive motor 12 has a first drive shaft 121 and a second drive shaft 122, which are respectively used to drive and connect the main fan 11 and the fresh air wheel 21. Each set of transmission components 30 includes a driving wheel 31 and a driven wheel 32 with magnetic coupling transmission. One of the main fan 11 and the fresh air wheel 21 is connected to the drive motor 12 through the transmission component 30. This arrangement helps to improve the overall energy efficiency of the air conditioner.

[0040] In the technical solution of this invention, the drive motor 12 is connected to one of the main fan 11 and the fresh fan 21 through a set of transmission components 30. The power of the drive motor 12 is then transmitted through the transmission components 30, driving one of the main fan 11 and the fresh fan 21 to rotate. Furthermore, the drive motor 12 is also connected to the other of the main fan 11 and the fresh fan 21, driving the other of the main fan 11 and the fresh fan 21 to rotate. On the one hand, there is no need to equip a separate drive motor 12 to drive the fresh fan 21, saving the installation space required for the drive motor 12 and contributing to a compact layout of the components within the air conditioner. Simultaneously, The drive motor 12 simultaneously drives the main fan wheel 11 and the fresh fan wheel 21 to rotate. On the other hand, the transmission assembly 30 includes a driving wheel 31 and a driven wheel 32 with magnetic coupling transmission. Through the magnetic field force between the driving wheel 31 and the driven wheel 32, the power of the drive motor 12 can be transmitted. Compared with traditional mechanical transmission, the driving wheel 31 and the driven wheel 32 do not need to be in direct contact, which effectively avoids friction between the driving wheel 31 and the driven wheel 32 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 assembly 30.

[0041] 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 unitary air conditioner.

[0042] The driving wheel 31 and the driven wheel 32 are driven by magnetic coupling. It is understood that both the driving wheel 31 and the driven wheel 32 are provided with magnetic structures, such as permanent magnets with at least a number of different magnetic poles, so as to use the interaction force between the magnetic poles to complete the power transmission between the driving wheel 31 and the driven wheel 32.

[0043] 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 22 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 a 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.

[0044] Because the drive motor 12 is located between the main fan wheel 11 and the fresh fan wheel 21, and the first drive shaft 121 and the second drive shaft 122 are located on opposite sides of the drive motor 12, the drive motor 12 can drive the main fan wheel 11 and the fresh fan wheel 21. This not only makes reasonable use of the installation space between the main fan wheel 11 and the fresh fan wheel 21, but also helps to improve the compactness of the main fan wheel 11, the fresh fan wheel 21 and the transmission assembly 30, thereby reliably reducing the size of the air conditioner. It also facilitates independent control of the movement of the first drive shaft 121 and the second drive shaft 122, thereby improving the control accuracy and control flexibility of the drive motor 12.

[0045] In this design, the first drive shaft 121 and the second drive shaft 122 can be two relatively independent shafts. Synchronous control of the first drive shaft 121 and the second drive shaft 122 can be achieved using a corresponding control module, clutch 40, or relay, while simultaneously controlling the rotation of the main impeller 11 and the fresh impeller 21. Alternatively, one of the main impeller 11 or the fresh impeller 21 can be controlled to rotate while the other remains stationary, or the first drive shaft 121 and the second drive shaft 122 can be controlled to rotate at a differential speed to meet user needs. However, this design is not limited to this. In other embodiments, independent control of the main impeller 11 and the fresh impeller 21 can be achieved by decoupling the magnetic coupling between the driving wheel 31 and the driven wheel 32.

[0046] Optionally, in an embodiment of the present invention, the first drive shaft 121 is connected to the main impeller 11 via the transmission assembly 30, and the second drive shaft 122 is connected to the new impeller 21. It is understood that the drive motor 12 drives the main impeller 11 to rotate via the transmission assembly 30. Specifically, the driving wheel 31 is connected to the first drive shaft 121 of the drive motor 12, and the driven wheel 32 is connected to the main impeller 11. Furthermore, through the magnetic field force between the driving wheel 31 and the driven wheel 32, the power of the drive motor 12 is transmitted to the driven wheel 32 via the driving wheel 31, thereby driving the main impeller 11 to rotate. This achieves high-precision transmission of the main impeller 11 and reduces operating noise and energy loss when controlling the rotation of the main impeller 11. Also, because the second drive shaft 122 is connected to the new impeller 21, the drive motor 12 can also drive the new impeller 21 to rotate, achieving synchronous or independent driving of the main impeller 11 and the new impeller 21 by the drive motor 12.

[0047] Furthermore, in an embodiment of the present invention, the transmission assembly 30 is provided in two sets. One of the two transmission assemblies 30 is connected to the first drive shaft 121 and the main fan wheel 11, and the other is connected to the second drive shaft 122 and the fresh fan wheel 21. It can be understood that the drive motor 12 controls the rotation of the main fan wheel 11 and the fresh fan wheel 21 respectively through the two sets of transmission assemblies 30. Since each set of transmission assemblies 30 includes the main fan wheel 11 and the fresh fan wheel 21 with magnetic coupling transmission, this arrangement facilitates high-precision transmission of the main fan wheel 11 and the fresh fan wheel 21, while reducing the operating noise and energy loss of the air conditioner, thereby reliably improving the overall energy efficiency of the air conditioner.

[0048] The two drive wheels 31 of the two sets of transmission components 30 are respectively connected to the first drive shaft 121 and the second drive shaft 122, and the two driven wheels 32 are respectively connected to the main fan wheel 11 and the fresh fan wheel 21. Thus, the power of the drive motor 12 is transmitted to the driven wheels 32 through the drive wheels 31, thereby driving the main fan wheel 11 and the fresh fan wheel 21 to rotate, thus completing the drive of the drive motor 12 to drive the main fan wheel 11 and the fresh fan wheel 21.

[0049] Please refer to 2 to 4. In the embodiments of the present invention, the first drive shaft 121 is connected to the main impeller 11, and the second drive shaft 122 is connected to the new impeller 21 through the transmission assembly 30. It can be understood that the drive motor 12 drives the new impeller 21 to rotate through the transmission assembly 30. Specifically, the driving wheel 31 is connected to the second drive shaft 122 of the drive motor 12, and the driven wheel 32 is connected to the new impeller 21. Furthermore, through the magnetic field force between the driving wheel 31 and the driven wheel 32, the power of the drive motor 12 is transmitted to the driven wheel 32 through the driving wheel 31, thereby driving the new impeller 21 to rotate. This not only achieves high-precision transmission of the new impeller 21, but also reduces the operating noise and energy loss when controlling the rotation of the new impeller 21. Also, because the first drive shaft 121 is connected to the main impeller 11, the drive motor 12 can also drive the main impeller 11 to rotate, realizing synchronous driving or independent driving of the main impeller 11 and the new impeller 21 by the drive motor 12.

[0050] Optionally, in an embodiment of the present invention, the diameter of the driven wheel 32 is smaller than the diameter of the driving wheel 31, and the driven wheel 32 is drivenly connected to the fresh air impeller 21. It is understood that by limiting the diameter of the driven wheel 32 to be smaller than the diameter of the driving wheel 31 under different positional relationships between the driving wheel 31 and the driven wheel 32, differential transmission between the driving wheel 31 and the driven wheel 32 can be achieved, thereby helping to reduce the power consumption of the drive motor 12 while meeting air treatment requirements. For example, if the rotational speed of the fresh air impeller 21 is greater than the rotational speed of the main impeller 11, the fresh air freshness of the indoor air can be effectively guaranteed. However, this design is not limited to this; in other embodiments, the diameter of the driving wheel 31 is smaller than or equal to the diameter of the driven wheel 32.

[0051] Optionally, in an embodiment of the present invention, both the driving wheel 31 and the driven wheel 32 are magnetic wheels, and the coupling gap 33L formed between the driving wheel 31 and the driven wheel 32 satisfies: 0.1mm≤L≤2mm. This coupling gap 33 is defined by the positions of the driving wheel 31 and the driven wheel 32. Therefore, while designing the positional relationship between the driving wheel 31 and the driven wheel 32, the coupling gap 33 between the driving wheel 31 and the driven wheel 32 is designed reasonably to ensure reliable power transmission between the driving wheel 31 and the driven wheel 32. At the same time, it effectively reduces the noise and wear caused by mechanical contact between the driving wheel 31 and the driven wheel 32, improves the service life of the transmission component 30, and improves the overall energy efficiency of the air conditioner and reduces maintenance costs.

[0052] The specific values ​​of the coupling gap 33 between the driving wheel 31 and the driven wheel 32 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 driven wheel 32 can be greater than 2mm or less than 0.1mm.

[0053] The following describes the positional relationship between the driving wheel 31 and the driven wheel 32.

[0054] Optionally, in one embodiment of the present invention, the driven wheel 32 is disposed on the periphery of the driving wheel 31, and a coupling gap 33 is formed between the two surfaces of the driving wheel 31 and the driven wheel 32 that are coupled together. It is understood that, since the driven wheel 32 is disposed on the periphery of the driving wheel 31, the two surfaces of the driving wheel 31 and the driven wheel 32 that are coupled together are the outer peripheral surface of the driving wheel 31 and the outer peripheral surface of the driven wheel 32, respectively. Furthermore, to avoid wear and noise caused by mechanical friction between the driving wheel 31 and the driven wheel 32, a certain coupling gap 33 is left between the outer peripheral surfaces of the driving wheel 31 and the driven wheel 32, while ensuring the transmission effect between them.

[0055] Specifically, taking the transmission assembly 30 connected between the drive motor 12 and the fresh air impeller 21 as an example, both the driving wheel 31 and the driven wheel 32 are located outside the fresh air module 20. The driving wheel 31 is connected to the drive motor 12 via the second drive shaft 122, and the driven wheel 32 is connected to the fresh air impeller 21 via a rotating shaft. Depending on the positional relationship between the main impeller 11 and the fresh air impeller 21, the driving wheel 31 can be located above, below, or behind the driven wheel 32. Furthermore, utilizing the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the driven wheel 32, the power of the drive motor 12 is transmitted to the driven wheel 32 via the driving wheel 31, causing the fresh air impeller 21 to rotate together with the driven wheel 32, drawing outdoor air 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 driven wheel 32 and / or the driving wheel 31 are located inside the fresh air module 20.

[0056] Optionally, in another embodiment of the present invention, the driven wheel 32 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 driven wheel 32 that are coupled together. It is understood that since the driven wheel 32 is disposed on the end side of the driving wheel 31, that is, the driven wheel 32 is arranged in the direction of the axial extension of the driving wheel 31, the two surfaces of the driving wheel 31 and the driven wheel 32 that are coupled together are the end face of the driving wheel 31 and the end face of the driven wheel 32, respectively. The axes of the driving wheel 31 and the driven wheel 32 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 driven wheel 32, a certain coupling gap 33 is left between the end faces of the driving wheel 31 and the driven wheel 32, while ensuring the transmission effect between them.

[0057] Specifically, taking the transmission assembly 30 connected between the drive motor 12 and the fresh air impeller 21 as an example, both the driving wheel 31 and the driven wheel 32 are located outside the fresh air module 20. The driving wheel 31 is connected to the drive motor 12 via the second drive shaft 122, and the driven wheel 32 is connected to the fresh air impeller 21 via a rotating shaft, or the driven wheel 32 is fixed to the center of the fresh air impeller 21 by embedding. Based on the positional relationship between the main impeller 11 and the fresh air impeller 21, the magnetic pole interaction force (attraction or repulsion) between the driving wheel 31 and the driven wheel 32 is used to transmit the power of the drive motor 12 to the driven wheel 32 via the driving wheel 31, causing the fresh air impeller 21 to rotate together with the driven wheel 32, and drawing outdoor air 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 driven wheel 32 is located inside the fresh air module 20, and the driving wheel 31 is located outside the fresh air module 20.

[0058] Optionally, in another embodiment of the present invention, the driving wheel 31 is provided with a groove for the driven wheel 32 to be inserted, and a coupling gap 33 is formed between the two surfaces of the driving wheel 31 and the driven wheel 32 that are coupled together. It is understood that since the driven wheel 32 is located within the groove of the driving wheel 31, the two surfaces of the driving wheel 31 and the driven wheel 32 that are coupled together are the inner circumferential surface of the driving wheel 31 and the outer circumferential surface of the driven wheel 32, respectively. The axes of the driving wheel 31 and the driven wheel 32 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 driven wheel 32, a certain coupling gap 33 is left between the inner circumferential surface of the driving wheel 31 and the outer circumferential surface of the driven wheel 32, while ensuring the transmission effect between them.

[0059] Specifically, taking the transmission assembly 30 connected between the drive motor 12 and the fresh air wheel 21 as an example, the driving wheel 31 and the driven wheel 32 are both located outside the fresh air module 20. The driving wheel 31 is connected to the drive motor 12 through the second drive shaft 122, and the driven wheel 32 is connected to the fresh air wheel 21 through a rotating shaft. According to the positional relationship between the main fan wheel 11 and the fresh air wheel 21, the power of the drive motor 12 is transmitted to the driven wheel 32 through the magnetic pole interaction force (attraction or repulsion force) between the driving wheel 31 and the driven wheel 32, so that the fresh air wheel 21 rotates together with the driven wheel 32 and drives the outdoor air into the air conditioner. At the same time, it ensures that the air conditioner maintains low noise and low wear during operation.

[0060] The coupling relationship between the driving wheel 31 and the driven wheel 32 described above also applies to the drive connection between the drive motor 12 and the main impeller 11.

[0061] Please see Figure 1 In an embodiment of the present invention, the air conditioner further includes a clutch 40 drivenly connected to the driven wheel 32. The clutch 40 is used to cause the driving wheel 31 and the driven wheel 32 to move relative to each other, having a linkage position and a stop position. Under the drive of the drive motor 12, in the linkage position, the main fan wheel 11 and the fresh fan wheel 21 rotate synchronously through magnetic coupling, and in the stop position, the fresh fan wheel 21 or the main fan wheel 11 stops rotating. This configuration can simultaneously drive the main fan wheel 11 and the fresh fan wheel 21 to rotate, thereby achieving indoor air conditioning. Furthermore, the clutch 40 can be used to release the power transmission between the driving wheel 31 and the driven wheel 32, enabling independent control of the main fan wheel 11 or the fresh fan wheel 21, thus meeting the user's needs.

[0062] The clutch 40 can be installed via screw connection, snap-fit, or other connection methods. Its installation location includes, but is not limited to, the fresh air housing 22 and the casing 13 of the fresh air module 20. To decouple the power transmission between the drive wheel 31 and the fresh air impeller 21, since the drive wheel 31 and driven wheel 32 are connected, the clutch 40 is driven by the driven wheel 32. Under the action of the clutch 40, the driven wheel 32 can move relative to the drive wheel 31, switching between the engaged position and the stopped position. When the driven wheel 32 is in the stopped position, because the gap between the drive wheel 31 and the driven wheel 32 is greater than the effective coupling gap 33, the magnetic field force between the drive wheel 31 and the driven wheel 32 is ineffective, and the power of the drive motor 12 cannot be transmitted to the driven wheel 32. That is, under the driving action of the drive motor 12, the main fan wheel 11 or the fresh air impeller 21 stops rotating. However, this design is not limited to this; in other embodiments, the clutch 40 is driven by the drive wheel 31.

[0063] Optionally, in embodiments of the present invention, the clutch 40 is configured as an electromagnetic clutch 40 to reduce the operating noise of the clutch 40. It is understood that when the clutch 40 is not energized, the two surfaces of the driving wheel 31 and the driven wheel 32 are coupled facing each other. Taking the transmission assembly 30 being driven between the drive motor 12 and the fresh air wheel 21 as an example, in one embodiment, the driven wheel 32 is connected to the fresh air wheel 21 via a rotating shaft, and the clutch 40 is located between the fresh air wheel 21 and the driven wheel 32, or the clutch 40 is located between the driving wheel 31 and the driven wheel 32. The driven wheel 32 is located away from the side of the fresh air wheel 21. The clutch 40 may be in the form of a ring and is fitted onto the rotating shaft. When the clutch 40 is energized, it generates an electromagnetic force that attracts the driven wheel 32 from the linkage position to the stop position. At this time, the driven wheel 32 is in contact with the clutch 40, and the gap between the driven wheel 32 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the driven wheel 32 and the driving wheel 31 is invalid, and the power of the drive motor 12 cannot be transmitted to the driven wheel 32 and the fresh air wheel 21.

[0064] In another embodiment, the clutch 40 is fixed to the fresh air housing 22 or the housing 13 and has a push rod extending toward the driven wheel 32. The clutch 40 is located between the fresh air wheel 21 and the driven wheel 32, or the clutch 40 is located on the side of the driven wheel 32 away from the fresh air wheel 21. When the clutch 40 is energized, the electromagnetic force generated by the clutch 40 pushes the push rod to abut against the driven wheel 32, and pushes the driven wheel 32 from the linkage position to the stop position by the applied thrust. At this time, the gap between the driven wheel 32 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the driven wheel 32 and the driving wheel 31 is invalid, and the power of the drive motor 12 cannot be transmitted to the driven wheel 32 and the fresh air wheel 21.

[0065] Taking the transmission assembly 30 connected between the drive motor 12 and the main impeller 11 as an example, in one embodiment, the driven wheel 32 is connected to the main impeller 11 through a rotating shaft. The clutch 40 is located between the main impeller 11 and the driven wheel 32, or the clutch 40 is located on the side of the driven wheel 32 away from the main impeller 11. The clutch 40 may be annular and fitted onto the rotating shaft. When the clutch 40 is energized, the clutch 40 generates electromagnetic force and attracts the driven wheel 32 from the linkage position to the stop position. At this time, the driven wheel 32 is in contact with the clutch 40, and the gap between the driven wheel 32 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the driven wheel 32 and the driving wheel 31 is invalid, and the power of the drive motor 12 cannot be transmitted to the driven wheel 32 and the main impeller 11.

[0066] In another embodiment, the clutch 40 is fixed to the fresh air housing 22 or the casing 13 and has a push rod extending toward the driven wheel 32. The clutch 40 is located between the main impeller 11 and the driven wheel 32, or on the side of the driven wheel 32 away from the main impeller 11. When the clutch 40 is energized, the electromagnetic force generated by the clutch 40 pushes the push rod to abut against the driven wheel 32, and the applied thrust moves the driven wheel 32 from the engaged position to the stopped position. At this time, the gap between the driven wheel 32 and the driving wheel 31 is greater than the effective coupling gap 33. In other words, the magnetic field force between the driven wheel 32 and the driving wheel 31 is ineffective, and the power of the drive motor 12 cannot be transmitted to the driven wheel 32 and the main impeller 11. However, this design is not limited to this. In other embodiments, the clutch 40 is configured as a mechanical clutch 40, which can also move the driven wheel 32 from the engaged position to the stopped position.

[0067] In addition, in order to ensure the synchronous rotation of the driven wheel 32 and the driving wheel 31, the air conditioner also includes a reset structure, which can be located in the clutch 40 or installed on the fresh air housing 22, for moving the driven wheel 32 from the stop position to the linkage position.

[0068] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
