[0035] In the prior art, please refer to Figure 6 and Figure 7For an air conditioner with a fresh air function, a heat exchanger 110 and a fresh air module 200 are usually arranged in the casing, wherein a main wind wheel 120 is installed in the air duct formed by the heat exchanger 110, and the main wind wheel 120 rotates under the drive of the main wind wheel motor 520, so that the heat on the heat exchanger 110 flows out from the air outlet of the air duct along with the air flow, thereby achieving the effect of indoor heat exchange. In addition, the fresh air module 200 includes a fresh air shell, a fresh air wheel 210 and a fresh air wheel motor 510, a fresh air duct is formed in the fresh air shell, the fresh air wheel 210 is installed in the fresh air duct, and rotates under the drive of the fresh air wheel motor 510, thereby transporting the outdoor fresh air to the room through the fresh air outlet 220 of the fresh air duct, thereby achieving the fresh air function. The main wind wheel 120 is connected to the main wind wheel motor 520, and the fresh air wind wheel 210 is connected to the fresh air wind wheel motor 510, so as to realize independent control of the main wind wheel 120 and the fresh air wind wheel 210. However, the two motors make the air conditioner heavier and larger in size. The independent operation of the two motors inevitably leads to the moment when they run at the same time. At this time, the operating noise of the two motors is relatively large, which brings a poor user experience.

[0036] The utility model provides an air conditioner.

[0037] Please refer to Figures 1 to 3 In one embodiment of the utility model, the air conditioner comprises:

[0038] A casing 100, wherein a main wind wheel 120 is disposed in the casing 100;

[0039] A fresh air module 200 is installed in the housing 100 . The fresh air module 200 is located at the end of the main wind wheel 120 . The fresh air module 200 is provided with a fresh air wind wheel 210 ; and

[0040] The driving motor 300 is located between the main wind wheel 120 and the fresh air wind wheel 210 , and is drivingly connected to the main wind wheel 120 and the fresh air wind wheel 210 , and is used to control the working states of the main wind wheel 120 and the fresh air wind wheel 210 .

[0041] The technical solution of the utility model sets a driving motor 300 drivingly connected to the main wind wheel 120 and the fresh air wind wheel 210 to realize the control of the rotation state of the main wind wheel 120 and the fresh air wind wheel 210. When the main wind wheel 120 and the fresh air wind wheel 210 need to rotate, the driving motor 300 runs, thereby driving the main wind wheel 120 and the fresh air wind wheel 210 to rotate. When the main wind wheel 120 and the fresh air wind wheel 210 do not need to rotate, the driving motor 300 stops running, so that the main wind wheel 120 and the fresh air wind wheel 210 stop rotating. In addition, the driving motor 300 is located between the main wind wheel 120 and the fresh air wind wheel 210, and the existing space between the main wind wheel 120 and the fresh air wind wheel 210 is used to reduce the volume of the air conditioner increased by arranging the driving motor 300 there. In this way, by setting up a driving motor 300, the operating status of the main wind wheel 120 and the fresh air wind wheel 210 can be controlled, the air outlet control of the air conditioner equipped with the fresh air function can be realized, the weight and volume of the air conditioner can be reduced, and the noise generated by the air conditioner can be reduced.

[0042] It can be understood that a main air duct is formed in the housing 110, and a heat exchanger 110 is arranged upstream or downstream of the main wind wheel 120. When the air conditioner is in cooling mode, the heat exchanger 110 is an evaporator for generating cold air. When the air conditioner is in heating mode, the heat exchanger 110 is a condenser for generating hot air. During the rotation of the main wind wheel 120, a negative pressure is formed at the main wind wheel 120, and the air flow passing through the heat exchanger 110 is transported to the room through the main air duct, thereby achieving indoor air conditioning. Of course, the air conditioning referred to here is not limited to temperature regulation. In the case where the housing 100 has a humidity module, the main wind wheel 120 can also transport the humidified gas to the room through the main air duct. Similarly, a fresh air duct is formed in the fresh air module 200, and the air inlet of the fresh air duct is connected to the outside. After being processed in the fresh air module 200 or processed by outdoor equipment, the fresh air is transported to the room from the fresh air outlet 220 through the fresh air duct.

[0043] Among them, compared with the fresh air impeller 210 and the main impeller 120 being driven by two power components respectively, this embodiment reduces one power component and meets the noise reduction requirements. As for the driving relationship between the drive motor 300 and the main impeller 120 and the fresh air impeller 210, the output end of the drive motor 300 can be configured as two to achieve independent control of the fresh air impeller 210 and the main impeller 120, or the output end of the drive motor 300 can also be configured as one, outputting power through the main transmission circuit and the transmission branch circuit, the main transmission circuit is connected to one of the fresh air impeller 210 or the main impeller 120, and the transmission branch circuit is connected to the other. In addition, only components such as the heat exchanger 110 and the main impeller 120 can be set in the casing 100, and the fresh air module 200 is connected in parallel with the casing 100, or the fresh air module 200 is installed in the casing 100. Furthermore, the drive motor 300 can be installed in the casing 100 , or the drive motor 300 can also be installed in the fresh air module 200 , or the drive motor 300 is connected to both the casing 100 and the fresh air module 200 to ensure the installation stability of the drive motor 300 .

[0044] It should be noted that, in this embodiment, please refer to Figures 2 to 4 The drive motor 300 is located in the space between the main wind wheel 120 and the fresh air wind wheel 210. The axes of the three can be coaxially arranged or eccentrically arranged. It can be understood that the drive motor 300 and the fresh air module 200 are located at the same end of the main wind wheel 120. The output end of the drive motor 300 can be arranged toward the fresh air module 200 or toward the main wind wheel 120, or has two output ends, which are arranged toward the fresh air wind wheel 210 and the main wind wheel 120 respectively, so as to shorten the power transmission path of the drive motor 300, reduce the volume of the air conditioner, ensure the driving force of the drive motor 300 on the fresh air wind wheel 210 and the main wind wheel 120, and also facilitate the installation of the drive motor 300. In one embodiment, please refer to Figures 2 to 4, the output shaft of the driving motor 300 is connected to one of the fresh air rotor 210 and the main wind rotor 120 by transmission, and the driving motor 300 is also connected to the other of the main wind rotor 120 and the fresh air rotor 210 by transmission structure. The driving motor 300 can directly drive one of the fresh air rotor 210 and the main wind rotor 120 to rotate by rotating the output shaft. During the operation of the driving motor 300, the driving motor 300 also drives the other of the fresh air rotor 210 and the main wind rotor 120 to rotate by the transmission structure. Among them, the driving motor 300 can be provided with only one output shaft, which directly drives one of the wind rotors to rotate, and also drives the other wind rotor to rotate through the transmission structure; or, the driving motor 300 can also form two output shafts at opposite ends, one output shaft directly drives one wind rotor to rotate, and the other output shaft drives the other wind rotor to rotate through the transmission structure, so as to realize the control of different speeds of the main wind rotor 120 and the fresh air rotor 210, and adapt to the driving force requirements of the main wind rotor 120 and the fresh air rotor 210.

[0045] In this embodiment, please refer to Figures 2 to 4 , the first output shaft 310 and the second output shaft 320 are respectively provided at the opposite ends of the driving motor 300, the second output shaft 320 is connected to the main wind wheel 120 by transmission, and the first output shaft 310 is connected to the fresh air wind wheel 210 by a transmission structure. It should be noted that the first output shaft 310 and the second output shaft 320 of the driving motor 300 can rotate at the same time, and here, one of the first output shaft 310 or the second output shaft 320 is provided with a clutch 410 to realize independent control of the main wind wheel 120 and the fresh air wind wheel 210, or the first output shaft 310 and the second output shaft 320 of the driving motor 300 can also rotate independently, thereby realizing independent control of the main wind wheel 120 and the fresh air wind wheel 210. The first output shaft 310 controls the fresh air wind wheel 210 to rotate through the transmission structure, and the second output shaft 320 is directly connected to the main wind wheel by transmission, and the transmission ratio is changed by the transmission structure to meet the requirements of different rotation speeds and driving forces of the main wind wheel 120 and the fresh air wind wheel 210.

[0046] Of course, in other embodiments, the drive motor 300 can directly drive one of the fresh air wheel 210 or the main wind wheel 120 through an output shaft, and then be connected to the output shaft through a transmission structure to drive the other one, including: in another embodiment, a transmission wheel is provided on the only output shaft of the drive motor 300, and two transmission shafts are transmission-connected on both radial sides of the transmission wheel, and the two transmission shafts are transmission-connected to the fresh air wheel 210 and the main wind wheel 120 respectively, wherein the two transmission shafts and the transmission wheel can be a fixed transmission connection, and can also be selectively transmission-connected through a clutch to realize independent control of the fresh air wheel 210 and the driving wheel 311; or, in another embodiment, one end of the only output shaft of the drive motor 300 is connected to the drive motor 300, and the other end is connected to the main wind wheel 120, and the transmission structure The rotating shaft is connected to the fresh air wheel 210, and the output shaft and the transmission rotating shaft are transmitted through a transmission member, so as to realize the main control of the main wind wheel 120 and the secondary control of the fresh air wheel 210, which meets the starting frequency requirements of the air conditioner for the main wind wheel 120 and the fresh air wheel 210; or, in another embodiment, the only output shaft of the driving motor 300 is divided into two sections, one section is connected to the driving motor 300, and the other section is connected to the fresh air wheel 210 or one of the main wind wheel 120, and the transmission rotating shaft is connected to the other section, and the two sections of the output shaft can be selectively connected in transmission under the action of the clutch, and the transmission rotating shaft can also be selectively connected in transmission to any section of the output shaft through the transmission member, or the transmission member can also be selectively connected in transmission to the transmission rotating shaft through the clutch, so as to realize independent control of the fresh air wheel 210 and the main wind wheel 120.

[0047] Further, in this embodiment, please refer to Figures 2 to 4 The transmission structure includes a transmission shaft 420 parallel to the first output shaft 310, the first output shaft 310 and the transmission shaft 420 are connected by a transmission member, and the transmission shaft 420 is connected by a transmission member to the fresh air impeller 210. It can be understood that the transmission shaft 420 rotates simultaneously with the first output shaft 310 under the action of the transmission member, thereby pulling the fresh air impeller 210 to rotate, wherein the transmission member can be controlled not to be connected by transmission with the first output shaft 310 or the transmission shaft 420, so that the second output shaft 320 can drive the main impeller 120 to rotate alone, thereby realizing that a single drive motor 300 controls the operation of the fresh air impeller 210 and the main impeller 120, and simplifying the complexity of the transmission structure, reducing the volume of the air conditioner, and facilitating the installation and design of the air conditioner.

[0048] Further, in this embodiment, please refer to Figures 3 to 5, the first output shaft 310 is provided with a driving wheel 311, and the transmission shaft 420 is provided with a driven wheel 421, and the driving wheel 311 and the driven wheel 421 are connected to each other through a transmission member. Without loss of generality, the diameters of the driving wheel 311 and the driven wheel 421 can be selected to form different transmission ratios, so as to achieve transmission between the output shaft 310 and the transmission shaft 420 according to a preset transmission ratio, thereby allocating the power output by the output shaft 310 and the transmission shaft 420 to adapt to the power and speed requirements of driving the fresh air wheel 210 and the main wind wheel 120. Among them, the driving wheel 311 can be movably mounted on the first output shaft 310, and the driven wheel 421 can also be movably mounted on the transmission shaft 420 to achieve independent control of the first output shaft 310 or the transmission shaft 420, thereby independently controlling the fresh air wheel 210 and the main wind wheel 120. It can be understood that the driving wheel 311 and the driven wheel 421 are connected to each other through a transmission member. In one embodiment, Figures 2 to 4 As shown, the transmission member can be configured as a belt 430, which not only ensures stable transmission of the driving wheel 311 and the driven wheel 421, but also reduces the number of parts of the transmission structure and reduces the weight; or, in another embodiment, the transmission member is configured as a gear set, and the transmission ratio is adjusted by the gear set to achieve the function of speed change to control the air outlet efficiency of the main air duct and the fresh air duct, and also ensures the stability of the transmission between the driving wheel 311 and the driven wheel 421.

[0049] In one embodiment, please refer to Figures 3 to 5The transmission structure also includes a clutch 410 disposed on the first output shaft 310 or the transmission shaft 420. The clutch 410 is used to control the transmission relationship between the first output shaft 310 and the fresh air impeller. It can be understood that the clutch 410 can control the transmission connection relationship between the first output shaft 310 and the driving wheel 311. When the clutch 410 is not working, the first output shaft 310 and the driving wheel 311 do not interfere with each other, and the first output shaft 310 and the second output shaft 320 rotate synchronously, but the driving wheel 311 does not transmit power to the transmission member. When the clutch 410 is working, the first output shaft 310 and the driving wheel 311 rotate synchronously, thereby pulling the transmission shaft 420 to rotate, so as to realize the main wind wheel 120 and The fresh air impeller 210 operates simultaneously and independently; when the clutch 410 is not working, the transmission shaft 420 and the driven wheel 421 do not interfere with each other, the first output shaft 310 and the second output shaft 320 rotate synchronously, but the driven wheel 420 does not transmit power to the transmission wheel 420. When the clutch 410 is working, the driven wheel 421 and the transmission shaft 420 rotate synchronously, thereby pulling the fresh air impeller 210 to rotate, so as to realize the simultaneous operation and independent operation of the main impeller 120 and the fresh air impeller 210. In this way, the main impeller 120 and the fresh air impeller 210 are driven independently through the control of the clutch 410. Among them, the clutch 410 can be configured as an electromagnetic clutch 410, a hydraulic clutch 410 or a mechanical clutch 410. Of course, in other embodiments, the first output shaft 310 and the transmission shaft 420 can be independently configured with the clutch 410 to realize independent configuration.

[0050] Specifically, in this embodiment, please continue to refer to Figure 4 and Figure 5The clutch 410 includes an electromagnetic component (not shown) disposed on the transmission shaft 420 and a magnetic component (not shown) disposed on the driven wheel 421. The magnetic component is connected to an elastic component. When the electromagnetic component is energized, the electromagnetic component and the magnetic component are magnetically attracted to each other. When the electromagnetic component is de-energized, the elastic component can separate the magnetic component and the electromagnetic component. When the electromagnetic component is energized, the electromagnetic component generates a magnetic attraction force to make the magnetic component and the electromagnetic component magnetically attracted to each other, thereby pulling the driven wheel 421 and the transmission shaft 420 to fit closely. At this time, the first output shaft 310 rotates, and the power is transmitted from the driving wheel 311 to the driven wheel 421, and then from the driven wheel 421 to the transmission shaft 420, so as to realize independent control of the fresh air impeller 210. After the electromagnetic component is powered off, the magnetism of the electromagnetic component is weak or non-magnetic, so that the electromagnetic component and the magnetic component are no longer magnetically attracted. Under the action of the elastic component, the magnetic component is elastically reset, thereby pulling the driven wheel 421 to separate from the transmission shaft 420. At this time, the rotation of the first output shaft 310 is no longer transmitted to the driven wheel 421, and the transmission shaft 420 no longer rotates with the first output shaft 310, thereby realizing independent control of the fresh air wheel 210. In another embodiment, a clutch 410 may also be provided at the connection between the first output shaft 310 and the driving wheel 311 to realize the selective transmission control of the fresh air wheel 210 by the first output shaft 310, or a clutch 410 may also be provided at the connection between the second output shaft 320 and the main wind wheel 120 to realize the selective transmission control of the second output shaft 320 to the main wind wheel 210, thereby ensuring the reliability and stability of the independent control of the fresh air wheel 210 and the main wind wheel 120 by the drive motor 300.

[0051] In one embodiment, please refer to Figures 3 to 5 , the axis of the fresh air wheel 210 and the axis of the main wind wheel 120 are arranged in an off-axis manner. It can be understood that the first output shaft 310 and the transmission shaft 420 are arranged in parallel, that is, the two are arranged in an off-axis manner. In this case, the axis of the fresh air wheel 210 and the axis of the main wind wheel 120 are arranged in an off-axis manner, so that the second output shaft 320 is directly connected to the main wind wheel 120, and the transmission shaft 420 is directly connected to the fresh air wheel 210 to provide connection space and ensure the convenience of connection operation. Of course, in other embodiments, the axis of the fresh air wheel 210 and the axis of the main wind wheel 120 can also be on the same axis, and the first output shaft 310 and the second output shaft 320 are also on the same axis, and are respectively connected to the fresh air wheel 210 and the main wind wheel 120, so that one drive motor 300 can control the operating status of the fresh air wheel 210 and the main wind wheel 120.

[0052] In one embodiment, please refer to Figures 3 to 5, the transmission shaft 320 is arranged through the axis of the fresh air wheel 210 and can drive the fresh air wheel 210 to rotate, and the second output shaft 320 is arranged through the axis of the main wind wheel 120 and can drive the main wind wheel 120 to rotate. It can be understood that in the case where the axis of the fresh air wheel 210 and the axis of the main wind wheel 120 are arranged in different axes, the first output shaft 310 and the transmission shaft 420 are also arranged in parallel, so that the second output shaft 320 and the axis of the main wind wheel 120, the transmission shaft 420 and the axis of the fresh air wheel 210 can be coaxially connected, which reduces the complexity of the transmission structure and improves the assembly convenience of the air conditioner. In the case where the axis of the fresh air wheel 210 and the axis of the main wind wheel 120 are coaxially distributed, the first output shaft 310 and the second output shaft 320 can also be coaxially distributed and are on the same axis as the axis of the fresh air wheel 210 and the axis of the main wind wheel 120. In this way, it is ensured that the power of the driving motor 300 can be stably transmitted to the fresh air wheel 210 via the first output shaft 310, and stably transmitted to the main wind wheel 120 via the second output shaft 320, thereby ensuring the reliability of the control of the main wind wheel 120 and the fresh air wheel 210.

[0053] In one embodiment, please refer to Figure 3 , the fresh air module 200 is provided with an installation frame 230, the transmission structure is located in the installation frame 230, and the drive motor 300 is connected to the fresh air module 200. The installation frame 230 is formed outside the shell of the fresh air module 200, and forms a protective function and a guiding function of the installation position for the transmission structure composed of the transmission shaft 420, the transmission member, the driving wheel 311, the driven wheel 421 and the clutch 410, thereby improving the installation convenience of the transmission structure and the drive motor 300, and ensuring the use stability of the transmission structure.
