[0086] Some embodiments of the present application provide a wall-mounted air conditioner 10000.

[0087] Generally, the air conditioner is a split type air conditioner, including an indoor unit and an outdoor unit, the indoor unit and the outdoor unit are connected by a pipeline to transmit refrigerant, the indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 41.

[0088] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan and a throttling device, the compressor, the outdoor heat exchanger, the throttling device and the indoor heat exchanger 2 connected in sequence form a refrigerant circuit, the refrigerant circulates in the refrigerant circuit, and the outdoor heat exchanger and the indoor heat exchanger 2 respectively exchange heat with air to realize the cooling mode or the heating mode of the air conditioner.

[0089] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form high-pressure refrigerant.

[0090] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transmitted in the outdoor heat exchanger, for example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor is condensed by emitting heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the refrigerant after pressure reduction is evaporated by absorbing the heat of the outdoor air through the outdoor heat exchanger.

[0091] In some embodiments, the outdoor heat exchanger can include heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0092] The outdoor fan is configured to suck the outdoor air into the outdoor unit and send the outdoor air after heat exchange with the outdoor heat exchanger to the outside, and the outdoor fan provides power for the flow of outdoor air.

[0093] The throttling device is connected between the outdoor heat exchanger and the indoor heat exchanger 2, and is used to adjust the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2, so as to adjust the flow of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger 2. The flow and pressure of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger 2 will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger 2, and the throttling device can be a throttling pipe, an electronic valve, etc. When the throttling device is an electronic valve, the opening degree of the throttling device is adjustable to adjust the flow and pressure of the refrigerant flowing through the throttling device.

[0094] In some schemes, the air conditioner can include a four-way valve connected in the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit to make the air conditioner execute the cooling mode or the heating mode.

[0095] The indoor heat exchanger 2 is configured to exchange heat between indoor air and refrigerant transmitted in the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 can include heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0096] The heat exchange fan 41 is configured to suck indoor air into the indoor unit and send the indoor air after heat exchange with the indoor heat exchanger 2 to the indoor. The heat exchange fan 41 provides power for the flow of indoor air.

[0097] The air conditioner can include a control device mainly used to control the working frequency of the compressor, the opening degree of the throttling member, and some control devices can also control the rotation speed of the outdoor fan and the rotation speed of the heat exchange fan 41, etc. The control device is connected with the compressor, the throttling member, the motor driving the rotation of the outdoor fan and the common motor 42 driving the rotation of the heat exchange fan 41 through data lines to transmit communication information.

[0098] The control device includes a processor, which can include a central processing unit (CPU), a microprocessor, an application specific integrated circuit (ASIC), and can be configured to perform the corresponding operations described in the control device when the processor executes the program stored in the non-transitory computer readable medium coupled to the control device.

[0099] The non-transitory computer readable storage medium can include a magnetic storage device (for example, a hard disk, a floppy disk or a magnetic tape), a smart card or a flash memory device (for example, an erasable programmable read-only memory (EPROM), a card, a stick or a keyboard driver).

[0100] Most of the wall-mounted air conditioners are limited by volume and weight, and the functions that can be realized are relatively limited, and usually only indoor air can be cooled or heated. If the user turns on the air conditioner for a long time, he feels that the indoor air is relatively dirty and stuffy, and needs to open the window for ventilation, which is not only troublesome to operate, but also the indoor cold or warm air will quickly flow out of the window during the opening of the window, affecting people's comfort.

[0101] Some fresh air air conditioners in the related art suck fresh air from the outdoor through a fresh air device and discharge indoor air through an exhaust device. However, the heat exchange fan, the fresh air device and the exhaust device all need separate motors to drive, resulting in high cost and large volume of the wall-mounted air conditioner.

[0102] To solve the above problems, some embodiments of the utility model provide a wall -hanging air conditioner 10000, through make heat exchange fan, exhaust fan and fresh air fan share same motor, can reduce overall size, reduce motor quantity, save the cost.

[0103] For example, wall -hanging air conditioner 10000 is a kind of indoor unit. Wall -hanging air conditioner 10000 is usually installed on wall, for example, can be installed in the upper region of indoor wall.

[0104] The wall -hanging air conditioner 10000 according to the embodiments of the application is described in detail below. Figures 1-21 The wall -hanging air conditioner 10000 according to the embodiments of the application is described in detail below.

[0105] Referring to Figure 1 And Figure 2 As shown, the wall -hanging air conditioner 10000 according to the embodiments of the application includes a main body 1000, and the main body 1000 includes a casing 1, the inside of the casing 1 is formed with a receiving cavity V1, and the casing 1 is formed with a heat exchange air inlet 101 and a heat exchange air outlet 102. The casing 1 can play a protective role and constitute the overall appearance structure of the wall -hanging air conditioner 10000.

[0106] Generally, the casing 1 is a long strip-shaped shell, and the length direction of the casing 1 is arranged along the horizontal direction, that is, the casing 1 is installed on the wall along the transverse direction. In actual products, in order to discharge condensate water, the casing 1 in some embodiments is installed on the wall along the transverse direction and forms a small angle with the horizontal plane.

[0107] Referring to Figure 2 And Figure 3 The main body 1000 further includes an indoor heat exchanger 2 arranged in the receiving cavity V1. As described above, the indoor heat exchanger 2 is a ring in the refrigerant circuit, the inside of the indoor heat exchanger 2 circulates refrigerant, and is used for refrigerating or heating the air circulating on the surface of the indoor heat exchanger 2. In the wall -hanging air conditioner 10000, the indoor heat exchanger 2 is usually arranged along the length direction of the casing 1.

[0108] For example, the indoor heat exchanger 2 is a two-fold or three-fold heat exchanger, and each fold of the indoor heat exchanger 2 is a plate-shaped structure extending along the length direction.

[0109] Referring to Figures 3-5 The main body 1000 further includes a base 3 arranged in the receiving cavity V1. The base 3 is a mounting and supporting structure inside the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. For example, the base 3 is formed with a volute tongue air duct, and after the indoor air enters the casing 1, the indoor air is guided in the flow direction through the volute tongue air duct, so that the indoor air can flow through the indoor heat exchanger 2 with smaller resistance.

[0110] Referring to Figures 4-5The wall-mounted air conditioner 10000 further comprises a heat exchange fan 41 arranged in the volute tongue air duct. When the heat exchange fan 41 rotates, the air inside the air conditioner can be exchanged with the indoor space.

[0111] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which has low noise and large air volume, and the air outlet speed of the cross-flow fan is distributed more uniformly along the axial direction of the cross-flow fan, which is beneficial to increasing the air supply distance and range. Moreover, in the case of using a cross-flow fan and arranging the cross-flow fan along the length direction of the heat exchange fan 41, the airflow driven can flow through the entire indoor heat exchanger 2, thereby ensuring the balance of heat exchange efficiency at each position of the indoor heat exchanger 2.

[0112] By arranging the heat exchange air outlet 102 and the heat exchange air inlet 101 in the casing 1, the heat exchange fan 41 can suck indoor air into the casing 1 when operating. After the indoor air is heat exchanged with the indoor heat exchanger 2, the heat exchanged air is sent to the indoor space from the heat exchange air outlet 102.

[0113] In this way, the adjustment of the indoor environment temperature can be realized. The indoor heat exchanger 2 can act as an evaporator to provide a refrigeration airflow toward the indoor space from the heat exchange air outlet 102, or the indoor heat exchanger 2 can act as a condenser to provide a heating airflow toward the indoor space from the heat exchange air outlet 102.

[0114] In some embodiments, in the height direction of the main body 1000, the heat exchange air inlet 101 is located above the heat exchange air outlet 102, so that the air can be inhaled from the top and blown out from the bottom.

[0115] For example, the height direction of the main body 1000 is the up-down direction.

[0116] It can be understood that the main body 1000 is usually installed on the wall, and in order to avoid interfering with people's daily life, the main body 1000 is usually hung at a high position. By arranging the main body 1000 to blow out the heat exchange air from the bottom, the blown-out heat exchange air is not easily blocked by the roof and the ground, so that the heat exchange air has small resistance consumption during the blowing process and has a wide blowing range, so that the heat exchange air can flow to the entire indoor space as soon as possible, thereby improving the heat exchange efficiency.

[0117] Referring to Figure 1 and Figure 2 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air inlet 101 can inhale air from the top, so that air is not inhaled from the heat exchange air outlet 102, and the heat exchange air blown out from the heat exchange air outlet 102 is not directly sucked into the heat exchange air inlet 101, thereby reducing the heat exchange air idling without participating in the indoor heat exchange process.

[0118] In some embodiments, the heat exchange air inlet 101 is located at the top of the casing 1, i.e. in a region that is not visible to the user, thereby hiding the heat exchange air inlet 101 and improving the appearance of the wall-mounted air conditioner 10000.

[0119] In some embodiments, the heat exchange air outlet 102 is located at the front of the casing 1, i.e. the heat exchange air outlet 102 blows air to the front side of the main body 1000.

[0120] It will be appreciated that the side of the main body 1000 that is connected to the wall is generally referred to as the back or rear side, and the side opposite the rear side is generally referred to as the front side. Therefore, when the heat exchange air outlet 102 is located at the front of the casing 1, the air blown by the heat exchange air outlet 102 is away from the wall, and the air blowing resistance is small, and the air blowing range is wide.

[0121] In some embodiments, the heat exchange air outlet 102 is located at the front side of the casing 1 and close to the bottom, for example, the heat exchange air outlet 102 is located at the front lower corner of the casing 1. In this case, the heat exchange air blown by the heat exchange air outlet 102 flows forward and downward at the same time, so that the heat exchange air can sink and fall on a person or object on the ground after being sent to a certain distance, so that the person or object on the ground can be in the suitable indoor environment as soon as possible.

[0122] With reference to Figures 4-6 , the wall-mounted air conditioner 10000 further comprises a common motor 42, which is arranged in the accommodating cavity V1 and located at one end of the heat exchange fan 41 in the length direction. In this way, the installation and maintenance of the common motor 42 are facilitated, and the overall height and thickness of the main body 1000 do not need to be increased due to the arrangement of the common motor 42. Here, the height direction of the main body 1000 is consistent with the up-down direction, and the thickness direction of the main body 1000 is consistent with the front-rear direction.

[0123] In some embodiments, the wall-mounted air conditioner 10000 can comprise a motor support, which can be fixed on the base 3 and used to fix the common motor 42, so that the common motor 42 can be firmly installed on the main body 1000.

[0124] It will be appreciated that the wall-mounted air conditioner 10000 is generally in a long strip shape, and the length direction of the heat exchange fan 41 is the same as the length direction of the main body 1000, which is the left-right direction shown in Figures 1-4 .

[0125] With reference to Figure 5 , Figures 10-11 , Figures 17-19The wall-mounted air conditioner 10000 further comprises a fresh air fan 6, which is an axial-inlet and radial-outlet centrifugal fan. The fresh air fan 6 is located at the other end of the heat exchange fan 41 in the length direction, i.e., the fresh air fan 6 is located at the end of the heat exchange fan 41 away from the common motor 42.

[0126] With reference to Figure 5 , Figures 12-15 , Figures 20-21 The wall-mounted air conditioner 10000 further comprises an exhaust fan 7, which is an axial-inlet and radial-outlet centrifugal fan.

[0127] The exhaust fan 7 is located at the end of the heat exchange fan 41 away from the common motor 42, the common motor 42 is located at the same end of the heat exchange fan 41 as the exhaust fan 7, and the common motor 42 is located between the exhaust fan 7 and the heat exchange fan 41. The common motor 42 drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate synchronously in the working state.

[0128] The centrifugal fan itself has the characteristics of compact structure, large air volume and low noise, and the fan noise decreases significantly when the rotating speed decreases. Therefore, the fresh air fan 6 and the exhaust fan 7 can meet the demand of large air volume by selecting a centrifugal fan with a smaller size. The centrifugal fan has small vibration noise and is not easy to resonate with the indoor heat exchanger 2, which is conducive to reducing the vibration and noise of the wall-mounted air conditioner 10000 as a whole.

[0129] The fresh air fan 6 and the exhaust fan 7 both adopt centrifugal fans, and the air directions of the fresh air fan 6 and the exhaust fan 7 can be reasonably arranged. For example, the fresh air fan 6 is an axial-inlet and radial-outlet centrifugal fan, the exhaust fan 7 is an axial-inlet and radial-outlet centrifugal fan, the fresh air fan 6 and the exhaust fan 7 are both axial-inlet, and then the fresh air and the exhaust air are driven to be radial-outlet. The flow paths of the fresh air and the exhaust air do not need to overlap radially, and the paths do not need to intersect. This helps to reduce the design of the avoidance corner of the fresh air and exhaust air paths, reduce the air resistance and energy consumption, ensure the air volume, and reduce the noise.

[0130] In some embodiments, with reference to Figures 5-6 , Figures 10-11 The fresh air fan 6 is located at the left end of the heat exchange fan 41, the common motor 42 is located at the right end of the heat exchange fan 41, and the exhaust fan 7 is located at the right end of the common motor 42. When the wall-mounted air conditioner 10000 is cooling or heating, the heat exchange fan 41 operates to drive the indoor air entering the casing 1 from the heat exchange air inlet 101 to flow through the indoor heat exchanger 2.

[0131] The exhaust fan 7 and the heat exchange fan 41 are separated only by a common motor 42 and a motor bracket. The air inlets of the exhaust fan 7 and the heat exchange fan 41 are relatively close, allowing the exhaust fan 7 to draw air from the heat exchange fan 41. In other words, when the exhaust fan 7 rotates, it draws indoor air from the heat exchange inlet 101 into the casing 1 and directs it to the exhaust fan 7. This eliminates the need for additional openings on the casing 1 to allow separate airflow to the exhaust fan 7, reducing the number of openings on the casing 1, simplifying its manufacturing process, and increasing its aesthetic appeal. Furthermore, the heat exchange inlet 101 is generally quite large, resulting in a larger volume of indoor air drawn into the casing 1 through it. This leads to a larger airflow reaching the exhaust fan 7, thus accelerating the exhaust process.

[0132] In some embodiments, both the fresh air fan 6 and the exhaust fan 7 are centrifugal fans, and the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are all driven by the same motor. This not only saves the number of motors, reduces the overall size and saves costs, but also maintains the three fans stacked along the axial direction of the common motor 42.

[0133] In some embodiments, the centrifugal fan itself is relatively flat in the axial direction, and the coaxial arrangement of the fresh air fan 6 and the exhaust fan 7 can reduce the overall axial dimension occupied, so that the length of the main body 1000 does not need to be too long. Since the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are all driven by the same motor, the three fans rotate synchronously and in unison.

[0134] The fresh air fan 6, heat exchange fan 41, common motor 42 and exhaust fan 7 are arranged along the length of the main body 1000, rather than along the thickness or height of the main body 1000, so that the main body 1000 of the wall-mounted air conditioner 10000 has a slender shape and a thin and light appearance.

[0135] In some embodiments, the common motor 42 is an external rotor motor.

[0136] In other embodiments, the common motor 42 is an internal rotor motor.

[0137] Reference Figures 7-11 The wall-mounted air conditioner 10000 also includes a fresh air volute 8, within which a fresh air duct V01 is formed. A fresh air fan 6 is installed inside the fresh air volute 8, and a fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air volute 8. Rotation of the fresh air fan 6 allows outdoor air to enter the fresh air volute 8 through the fresh air inlet 801, and allows outdoor air entering the fresh air volute 8 to enter the room through the fresh air outlet 802.

[0138] In other words, the fresh air fan 6 is arranged in the fresh air duct V01, and the fresh air fan 6 rotates to allow outdoor air to enter the fresh air duct V01 from the fresh air inlet 801 and to allow the outdoor air in the fresh air duct V01 to enter the indoor environment from the fresh air outlet 802. The fresh air fan 6 is used to drive the air flow to be sucked from the fresh air inlet 801 and discharged to the indoor environment through the fresh air outlet 802. The operation of the fresh air fan 6 provides the driving force for the fresh air flow.

[0139] Therefore, by arranging the fresh air duct V01 in cooperation with the fresh air fan 6, when the air in the indoor environment is relatively dirty or the air quality is poor, the relatively fresh outdoor air can be driven by the fresh air fan 6 to enter the indoor environment to improve the air flow environment in the indoor environment.

[0140] In some embodiments, the number of fresh air outlets 802 can be one.

[0141] In some embodiments, the number of fresh air outlets 802 can be multiple, for example, two, three, four or more. By arranging multiple fresh air outlets 802, the air discharge amount can be increased.

[0142] In some embodiments, the number of fresh air outlets 802 is multiple, and the multiple fresh air outlets 802 are arranged in the same direction, for example, the multiple fresh air outlets 802 are all arranged to discharge air to the top of the main body 1000.

[0143] In some embodiments, the number of fresh air outlets 802 is multiple, and the multiple fresh air outlets 802 are arranged in different directions, for example, some fresh air outlets 802 are arranged to discharge air to the top of the main body 1000, some fresh air outlets 802 are arranged to discharge air to the bottom of the main body 1000, and some fresh air outlets 802 are arranged to discharge air to the front of the main body 1000.

[0144] Referring to Figures 12-16 , the wall-mounted air conditioner 10000 further comprises an exhaust volute 90 located at the end of the common motor 42 away from the heat exchange fan 41, an exhaust air duct V02 is formed in the exhaust volute 90, and an exhaust fan 7 is arranged in the exhaust volute 90. The exhaust volute 90 is formed with an exhaust air inlet 901 and an exhaust air outlet 902. The exhaust fan 7 rotates to allow indoor air to enter the exhaust volute 90 from the exhaust air inlet 901 and to allow the indoor air in the exhaust volute 90 to be discharged to the outdoor environment from the exhaust air outlet 902.

[0145] In other words, the exhaust fan 7 is arranged in the exhaust air duct V02, and rotation of the exhaust fan 7 can cause indoor air to enter the exhaust air duct V02 from the exhaust air inlet 901 and to be exhausted to the outside from the exhaust air outlet 902. The exhaust fan 7 is configured to drive air flow to be sucked in from the exhaust air inlet 901 and exhausted to the outside from the exhaust air outlet 902. The operation of the exhaust fan 7 provides power for the flow of the dirty air.

[0146] Therefore, by arranging the exhaust air duct V02 in cooperation with the exhaust fan 7, when the indoor air is relatively dirty or the air quality is poor, the dirty air flow in the indoor space can be sucked away and exhausted by the exhaust fan 7. After the amount of indoor air is reduced, fresh air can be sucked in from the outside or from other rooms through doors and windows, so as to reduce the degree of dirtiness of the indoor air.

[0147] The fresh air fan 6 and the fresh air volute 8 constitute a fresh air device, and the exhaust fan 7 and the exhaust volute 90 constitute an exhaust device, which are arranged in the main body 1000. The fresh air device can provide fresh air for the indoor space, and the exhaust device can exhaust indoor air to the outside.

[0148] It should be noted that in the wall-mounted air conditioner 10000, the operation mode of the fresh air device and the exhaust device can be set according to actual use requirements.

[0149] In some embodiments, the fresh air device and the exhaust device together constitute a bidirectional ventilation assembly, which can simultaneously operate in a fresh air mode and an exhaust mode, i.e., the fresh air duct V01 and the exhaust air duct V02 are simultaneously opened, so that the dirty air flow in the indoor space is exhausted to the outdoor space at the same time as the fresh air flow from the outdoor space is introduced into the indoor space, and the in-out air flow driving combination is beneficial to increasing the improvement efficiency of the air flow in the indoor space, so as to timely meet the user's demand when the user urgently needs to exhaust or update the indoor air.

[0150] Moreover, since the indoor air is exhausted to the outdoor space at the same time as the fresh air from the outdoor space is introduced into the indoor space, the amount of indoor air is kept sufficient, so that it is easier to suck away the indoor air. For example, when there is a leakage of irritating gas (such as gas released by home decoration materials), coal gas or other gas in the indoor space, the bidirectional ventilation assembly can be simultaneously operated in the fresh air mode and the exhaust mode to achieve rapid ventilation, and compared with the conventional fresh air structure which simply introduces fresh air, the bidirectional ventilation assembly in some embodiments of the present application has a larger purification flow per unit time, a higher ventilation efficiency and a better purification effect.

[0151] Moreover, when ventilating, the ventilation is not too fast to cause a sharp change in the indoor temperature, so as to avoid causing discomfort of the indoor personnel due to a sharp rise or drop in the temperature. Moreover, the main body 1000 is located at a higher position, and the ventilation position will not cause discomfort due to being too close to the people.

[0152] In some embodiments, the bidirectional ventilation assembly can realize the one-or-the-other operation of the fresh air mode and the exhaust air mode by means of a valve, that is, when the bidirectional ventilation assembly is turned on in the fresh air mode, the exhaust air mode is turned off, at this time, only the fresh air duct V01 is ventilated, and the exhaust air duct V02 is not ventilated. Or when the bidirectional ventilation assembly is turned on in the exhaust air mode, the fresh air mode is turned off, at this time, the fresh air duct V01 is not ventilated, and the exhaust air duct V02 is ventilated.

[0153] It can be understood that when the wall-mounted air conditioner 10000 is in a cooling state, the bidirectional ventilation assembly inhales fresh air from the outdoor to the indoor, and the cold energy generated by the wall-mounted air conditioner 10000 can still remain in the indoor, and the loss of cold energy is small. The indoor air is discharged to the outdoor through the exhaust air duct V02, and by setting the exhaust air volume to be less than the fresh air volume, the loss of cold energy can be reduced.

[0154] The bidirectional ventilation assembly is arranged in the length direction of the heat exchange fan 41, and compared with the main body without the bidirectional ventilation assembly, only the transverse length is increased, and the height and thickness of the main body 1000 can be substantially unchanged or slightly changed, so that the main body 1000 is light and thin in appearance, and the wall-mounted air conditioner 10000 hung on the wall does not affect the indoor space layout due to being too conspicuous, and the wall-mounted air conditioner 10000 does not cause difficulty in fixation due to being too heavy, and the risk of falling off from the wall is reduced. The wall-mounted air conditioner 10000 is still a light and thin model, which is not only beautiful when hung on the wall, but also controllable in weight.

[0155] According to the wall-mounted air conditioner 10000 of the embodiment of the present application, the heat exchange fan 41, the exhaust air fan 7 and the fresh air fan 6 share the same motor, which can reduce the overall size, reduce the number of motors and save costs. The architecture of the wall-mounted air conditioner 10000 is arranged from right to left as follows: the exhaust air fan 7, the common motor 42, the heat exchange fan 41 and the fresh air fan 6, and the common motor 42 is between the heat exchange fan 41 and the exhaust air fan 7. The common motor 42 is close to the heat exchange fan 41 and the exhaust air fan 7, so that the radial runout of the heat exchange fan 41 and the exhaust air fan 7 is small, and the wall-mounted air conditioner 10000 runs stably and quietly.

[0156] Compared with the layout mode that the common motor 42 is arranged in the order of the common motor 42, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 from right to left, in the present application, the order is the exhaust fan 7, the common motor 42, the heat exchange fan 41 and the fresh air fan 6 from right to left, and the exhaust fan 7 and the fresh air fan 6 are respectively located at two ends of the common motor 42, which can reduce the length of the whole machine. If the exhaust fan 7 and the fresh air fan 6 are all located on the same side of the common motor 42, the gap size between the fan and the fan volute is affected by the cumulative tolerance and is increased. In addition, when the exhaust fan 7 and the fresh air fan 6 are all located on one side, the overall fan jump is large during high-speed rotation due to the fan gravity and the radial runout, which is not conducive to stable operation. The layout of the exhaust fan 7 and the fresh air fan 6 in the present application is better in stability, and the gap size between the fan and the fan volute is less affected by the cumulative tolerance. Therefore, the gap between the exhaust fan 7 and the exhaust volute 90 can be made smaller, and the gap between the fresh air fan 6 and the fresh air volute 8 can be made smaller, so as to reduce the length of the whole machine to the maximum extent.

[0157] In addition, if the layout mode that the common motor 42 is arranged in the order of the common motor 42, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 from right to left is adopted, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 need to be separately injection molded during forming, and then the injection molded fan is embedded in the next fan mold for secondary injection molding, and so on. The three injection moldings are needed to form, three positioning corrections of concentricity are needed, there are multiple positioning errors, cumulative errors are increased, and the manufacturing process is difficult, that is, the more the series connection, the greater the difficulty. Since the exhaust fan 7 is fixed with the common motor 42 in the layout mode of the present application that the exhaust fan 7, the common motor 42, the heat exchange fan 41 and the fresh air fan 6 are arranged in the order from right to left, the exhaust fan 7 does not need to be injection molded synchronously with other fans, so the production process difficulty is reduced.

[0158] The heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are driven by the same motor, can rotate and stop synchronously, and the rotating speed is consistent. In the related art, the fresh air fan is driven by a separate motor, and the exhaust fan is driven by a separate motor, which causes high cost. The mode that one motor drives three fans to rotate in the present application can save two motors, and greatly reduces the cost.

[0159] In some embodiments of the present application, as shown in FIG. 4, Figures 4-6 The common motor 42 includes a first output shaft 421, the exhaust fan 7 is fixedly connected with the first output shaft 421, and the first output shaft 421 drives the exhaust fan 7 to rotate in the working state of the common motor 42. The non-circular surface cooperation or interference fit between the exhaust fan 7 and the first output shaft 421 can prevent relative rotation between the exhaust fan 7 and the first output shaft 421.

[0160] In some embodiments of the present application, with reference to Figures 4-6 As shown in the figure, the common motor 42 includes a second output shaft 422, and the heat exchange fan 41 is fixedly connected with the second output shaft 422. In the working state of the common motor 42, the second output shaft 422 drives the heat exchange fan 41 to rotate, and the heat exchange fan 41 drives the fresh air fan 6 to rotate. The heat exchange fan 41 and the second output shaft 422 can be non-circular surface matched or interference fitted to prevent relative rotation between the heat exchange fan 41 and the second output shaft 422.

[0161] The wall-mounted air conditioner 10000 further includes a transmission shaft 43, the common motor 42 includes a first output shaft 421 and a second output shaft 422, the exhaust fan 7 is fixedly connected with the first output shaft 421, the heat exchange fan 41 is fixedly connected with the second output shaft 422, the fresh air fan 6 is fixedly connected with the transmission shaft 43, and the heat exchange fan 41 has a fan shaft 411. The transmission shaft 43 and the fan shaft 411 are connected through a shaft coupling 44, so that when the second output shaft 422 drives the heat exchange fan 41 to rotate, the transmission shaft 43 drives the fresh air fan 6 to rotate. In this way, the second output shaft 422 does not have to be fixedly connected with the fresh air fan 6 after passing through the heat exchange fan 41, and the second output shaft 422 does not have to be made too long, and the common motor 42 has better dynamic balance. At this time, in the working state of the common motor 42, the first output shaft 421 drives the exhaust fan 7 to rotate, the second output shaft 422 drives the heat exchange fan 41 to rotate synchronously, the heat exchange fan 41 drives the transmission shaft 43 to rotate, and the transmission shaft 43 drives the fresh air fan 6 to rotate. The fresh air fan 6 and the transmission shaft 43 can be non-circular surface matched or interference fitted to prevent relative rotation between the fresh air fan 6 and the transmission shaft 43.

[0162] In this way, one common motor 42 drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate, the number of motors is small, and the cost is saved.

[0163] In some embodiments not shown in the figure, the common motor 42 includes a first output shaft 421 and a second output shaft 422, the exhaust fan 7 is fixedly connected with the first output shaft 421, and the heat exchange fan 41 and the fresh air fan 6 are both fixedly connected with the second output shaft 422. The exhaust fan 7 and the first output shaft 421 can be non-circular surface matched or interference fitted to prevent relative rotation between the exhaust fan 7 and the first output shaft 421, the heat exchange fan 41 and the second output shaft 422 can be non-circular surface matched or interference fitted to prevent relative rotation between the heat exchange fan 41 and the second output shaft 422, and the fresh air fan 6 and the second output shaft 422 can be non-circular surface matched or interference fitted to prevent relative rotation between the fresh air fan 6 and the second output shaft 422.

[0164] In some embodiments not shown in the drawings, the wall-mounted air conditioner 10000 further comprises a transmission shaft 43, which is adapted to be fixedly connected with the heat exchange fan 41 and the fresh air fan 6. When the second output shaft 422 drives the heat exchange fan 41 to rotate, the heat exchange fan 41 drives the fresh air fan 6 to rotate synchronously through the transmission shaft 43, thereby saving the motor and reducing the cost.

[0165] In some embodiments of the present application, the second output shaft 422 is coaxially arranged with the transmission shaft 43.

[0166] In some embodiments of the present application, the transmission shaft 43 is adapted to be formed in one piece with one of the heat exchange fan 41 and the fresh air fan 6, and the other one of the heat exchange fan 41 and the fresh air fan 6 is fixedly installed on the transmission shaft 43.

[0167] For example, the transmission shaft 43 is formed in one piece with the heat exchange fan 41, and the fresh air fan 6 is fixedly installed on the transmission shaft 43. The transmission shaft 43 and the heat exchange fan 41 can be fixedly connected by welding or be an integrally injection-molded piece. The fresh air fan 6 and the transmission shaft 43 can be non-circular surface matched or interference fitted to prevent relative rotation between the fresh air fan 6 and the transmission shaft 43.

[0168] For another example, the transmission shaft 43 is formed in one piece with the fresh air fan 6, and the heat exchange fan 41 is fixedly installed on the transmission shaft 43. The transmission shaft 43 and the fresh air fan 6 can be fixedly connected by welding or be an integrally injection-molded piece. The heat exchange fan 41 and the transmission shaft 43 can be non-circular surface matched or interference fitted to prevent relative rotation between the heat exchange fan 41 and the transmission shaft 43.

[0169] In some embodiments of the present application, as shown in Figures 3-4 , Figures 12-16 The exhaust volute 90 comprises an exhaust volute half 9 located at the end of the common motor 42 away from the heat exchange fan 41.

[0170] In some embodiments of the present application, the exhaust volute 90 further comprises an exhaust volute part 122 adapted to be detachably connected with the exhaust volute half 9. The exhaust volute part 122 and the exhaust volute half 9 form an exhaust air duct V02 therein, and the exhaust fan 7 is installed in the exhaust air duct V02. The detachable connection between the exhaust volute part 122 and the exhaust volute half 9 facilitates the installation and dismounting of the exhaust fan 7 in the exhaust volute 90.

[0171] In some embodiments of the present application, the exhaust volute half 9 and the exhaust volute part 122 enclose an exhaust air inlet 901, and an exhaust air outlet 902 is arranged on the exhaust volute half 9.

[0172] In some embodiments of the present application, the air exhaust air inlet 901 includes a first air exhaust air inlet 9011 and a second air exhaust air inlet 9012. The first air exhaust air inlet 9011 is arranged on the side of the air exhaust volute 90 facing the common motor 42, and the second air exhaust air inlet 9012 is arranged on the side of the air exhaust volute 90 away from the common motor 42. As shown in Figures 12-13 , the left side of the air exhaust volute 90 is provided with the first air exhaust air inlet 9011, and the right side of the air exhaust volute 90 is provided with the second air exhaust air inlet 9012. Thus, when the air exhaust device is exhausting air, air can be simultaneously introduced into the air exhaust volute 90 from both sides of the air exhaust volute 90, thereby improving the air intake efficiency.

[0173] In some embodiments of the present application, as shown in Figure 16 , Figures 20-21 , the air exhaust fan 7 includes an air exhaust wheel disc 71 fixedly connected with the first output shaft 421. When the first output shaft 421 rotates, it drives the air exhaust wheel disc 71 to rotate, thereby realizing the rotation of the air exhaust fan 7.

[0174] In some embodiments of the present application, the air exhaust fan 7 includes air exhaust blades 72 extending along the axial direction of the air exhaust wheel disc 71 towards the heat exchange fan 41. When the air exhaust fan 7 rotates, the air exhaust blades 72 are used to stir air to generate air flow.

[0175] In some embodiments of the present application, the air exhaust wheel disc 71 is formed with air exhaust wheel disc holes 712 penetrating through the air exhaust wheel disc 71 along the axial direction of the air exhaust fan 7. Air on one side of the air exhaust wheel disc 71 can reach the other side of the air exhaust wheel disc 71 through the air exhaust wheel disc holes 712.

[0176] In some embodiments of the present application, the distance from the air exhaust wheel disc holes 712 to the center of the air exhaust wheel disc 71 is less than the distance from the air exhaust blades 72 to the center of the air exhaust wheel disc 71. Thus, the air exhaust wheel disc holes 712 can better realize the air communication between the two sides of the air exhaust wheel disc 71, so that air on one side of the air exhaust wheel disc 71 can reach the other side of the air exhaust wheel disc 71 more quickly through the air exhaust wheel disc holes 712.

[0177] In some embodiments of the present application, the air exhaust wheel disc 71 at least partially extends towards the heat exchange fan 41 to form an air exhaust recess 711. This can adjust the center of gravity of the air exhaust fan 7 to the middle, which is beneficial to improve the unbalance of the air exhaust fan 7 when it rotates.

[0178] In some embodiments of the present application, as shown in Figures 3-4 , Figures 7-11 , the fresh air volute 8 includes a first volute half 81 located on the side of the heat exchange fan 41 away from the common motor 42.

[0179] In some embodiments of the present application, the new air volute 8 further comprises a new air volute part 121, which is detachably connected with the first volute half 81 and forms a part of the new air duct V01 in the first volute half 81. Figures 3-4 、 Figures 7-11 The new air volute part 121 and the exhaust air volute part 122 are separate parts. When the bidirectional ventilation assembly is installed on the main body 1000, the exhaust air fan 7, the common motor 42, the heat exchange fan 41 and the new air fan 6 are assembled into a motor fan assembly first, then the first volute half 81 and the exhaust air volute half 9 are installed on the base 3, and then the motor fan assembly is installed on the main body 1000 so that the new air fan 6 is located in the first volute half 81 and the exhaust air fan 7 is located in the exhaust air volute half 9. Finally, the new air volute part 121 is connected and fixed with the first volute half 81 by fasteners, and the exhaust air volute part 122 is connected and fixed with the exhaust air volute half 9 by fasteners, so that the new air volute part 121 covers the new air fan 6 and the exhaust air volute part 122 covers the exhaust air fan 7.

[0180] In some embodiments, as shown in Figures 3-4 、 Figures 7-16 The new air volute part 121 and the exhaust air volute part 122 are separate parts. When the bidirectional ventilation assembly is installed on the main body 1000, the exhaust air fan 7, the common motor 42, the heat exchange fan 41 and the new air fan 6 are assembled into a motor fan assembly first, then the first volute half 81 and the exhaust air volute half 9 are installed on the base 3, and then the motor fan assembly is installed on the main body 1000 so that the new air fan 6 is located in the first volute half 81 and the exhaust air fan 7 is located in the exhaust air volute half 9. Finally, the new air volute part 121 is connected and fixed with the first volute half 81 by fasteners, and the exhaust air volute part 122 is connected and fixed with the exhaust air volute half 9 by fasteners, so that the new air volute part 121 covers the new air fan 6 and the exhaust air volute part 122 covers the exhaust air fan 7.

[0181] Optionally, the fasteners can be bolts, screws, etc., which can firmly connect two parts.

[0182] Optionally, the new air volute part 121 and the first volute half 81 can also be connected and fixed by a buckle structure, and the exhaust air volute part 122 and the exhaust air volute half 9 can also be connected and fixed by a buckle structure.

[0183] In some embodiments, as shown in Figure 3 A part of the first exhaust air inlet 9011 is formed on the exhaust air volute half 9, another part is formed on the exhaust air volute part 122, and the axial direction of the first exhaust air inlet 9011 is arranged along the length direction of the heat exchange fan 41. The first exhaust air inlet 9011 is opposite to the axial air inlet end of the exhaust air fan 7, so that the air resistance at the first exhaust air inlet 9011 is small, which is beneficial to ensure the exhaust air inlet amount. When the exhaust air inlet is easy, a smaller size exhaust air fan 7 can be selected to further reduce the size of the exhaust air volute 90.

[0184] The first exhaust air inlet 9011 is axially directed to the indoor heat exchanger 2, so that the air inlet area of the first exhaust air inlet 9011 is directed to the indoor heat exchanger 2, the first exhaust air inlet 9011 is closer to the heat exchange air inlet 101, the air volume at the heat exchange air inlet 101 is larger, and part of the air entering the casing 1 from the heat exchange air inlet 101 can enter the exhaust air duct V02 through the first exhaust air inlet 9011, so that the air volume at the first exhaust air inlet 9011 is sufficient.

[0185] In some embodiments, as shown in Figure 3 , a part of the second exhaust air inlet 9012 is formed on the exhaust air volute half 9, another part is formed on the exhaust air volute portion 122, and the axial direction of the second exhaust air inlet 9012 is arranged along the length direction of the heat exchange fan 41. The second exhaust air inlet 9012 is opposite to the axial air inlet end of the exhaust air fan 7, so that the air resistance at the second exhaust air inlet 9012 is small, which is beneficial to ensure the exhaust air inlet volume. When the exhaust air inlet is relatively easy, a smaller size exhaust air fan 7 can be selected to further reduce the size of the exhaust air volute 90. Part of the air entering the casing 1 from the heat exchange air inlet 101 can enter the exhaust air duct V02 through the second exhaust air inlet 9012. Thus, the first exhaust air inlet 9011 and the second exhaust air inlet 9012 simultaneously inlet air, which improves the air inlet efficiency.

[0186] In some embodiments, the heat exchange air inlet 101 and the first exhaust air inlet 9011 form a first communication air duct, the indoor air is driven by the rotation of the exhaust air fan 7 to enter the first communication air duct from the heat exchange air inlet 101, and the indoor air enters the exhaust air duct V02 through the first exhaust air inlet 9011.

[0187] In some embodiments, the heat exchange air inlet 101 and the second exhaust air inlet 9012 form a second communication air duct, the indoor air is driven by the rotation of the exhaust air fan 7 to enter the second communication air duct from the heat exchange air inlet 101, and the indoor air enters the exhaust air duct V02 through the second exhaust air inlet 9012.

[0188] That is, the heat exchange air inlet 101 and the first exhaust air inlet 9011, the heat exchange air inlet 101 and the second exhaust air inlet 9012 do not need to be connected by a pipe, and the airflow is only sucked from the top by air pressure.

[0189] In some embodiments of the present application, referring to Figures 3-4 , Figures 7-11 , the fresh air volute 8 further includes a second volute 82, the second volute 82 is located on the side of the first volute half 81 away from the heat exchange fan 41, and the second volute 82 is detachably connected with the first volute half 81.

[0190] In some embodiments of the present application, the second volute 82 comprises a second volute half 821 located on the side of the first volute half 81 away from the heat exchange fan 41, and the second volute half 821 is detachably connected with the first volute half 81. The second volute half 821 is provided with an axial air vent 8211. The second volute half 821, the fresh air volute part 121 and the first volute half 81 form a volute cavity V011 in which the fresh air fan 6 is located.

[0191] In some embodiments of the present application, the second volute 82 further comprises a fan cover 822 located on the side of the second volute half 821 away from the heat exchange fan 41, and the fan cover 822 is detachably connected with the second volute half 821. The cavity enclosed by the fan cover 822 and the second volute half 821 is a fresh air cavity V012.

[0192] In some embodiments of the present application, the second volute half 821 and the fan cover 822 enclose a fresh air inlet 801, and the fresh air outlet 802 is formed on the fresh air volute part 121.

[0193] In some embodiments not shown in the drawings, the fresh air inlet 801 is formed on the fan cover 822, and the second volute half 821 and the fresh air volute part 121 enclose the fresh air outlet 802.

[0194] By machining the fresh air volute 8 into at least the first volute half 81, the second volute half 821, the fan cover 822 and the fresh air volute part 121 respectively, and machining the exhaust air volute 90 into at least the exhaust air volute half 9 and the exhaust air volute part 122 respectively, the manufacturing and assembly difficulty can be reduced. Moreover, the quality control of such a complex shell can be facilitated after being manufactured in parts. The detachable connection between the parts facilitates assembly and subsequent adjustment and maintenance.

[0195] It can be understood that the detachable connection between the two parts can be achieved by fasteners or by a buckle structure.

[0196] In some embodiments, the exhaust air fan 7 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the exhaust air fan 7 can also be a resin part, a metal part, etc.

[0197] In some embodiments, the fresh air fan 6 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the fresh air fan 6 can also be a resin part, a metal part, etc.

[0198] Similarly, the exhaust air volute half 9 can be a plastic part, so as to be light in weight and low in cost. For example, the exhaust air volute half 9 can be an injection molded part. In some embodiments, the exhaust air volute half 9 can also be a resin part, a metal part, etc.

[0199] Similarly, the exhaust volute 122 can be made of plastic, thus being lightweight and low-cost. For example, the exhaust volute 122 can be an injection-molded part. In some embodiments, the exhaust volute 122 can also be made of resin, metal, etc.

[0200] The first volute half 81 can be made of plastic, thus being lightweight and low-cost. For example, the first volute half 81 can be an injection-molded part. In some embodiments, the first volute half 81 can also be a resin part, a metal part, etc.

[0201] The fresh air volute 121 can be made of plastic, thus being lightweight and low-cost. For example, the fresh air volute 121 can be an injection-molded part. In some embodiments, the fresh air volute 121 can also be made of resin, metal, etc.

[0202] The second volute 82 can be made of plastic, thus being lightweight and low-cost. For example, the second volute 82 can be an injection-molded part. In some embodiments, the second volute 82 can also be a resin part, a metal part, etc.

[0203] In some embodiments of this application, reference is made to Figures 2-5 , Figures 7-11 The wall-mounted air conditioner 10000 also includes a purification component 11, which is installed in the fresh air duct V01 to purify the fresh air blown into the room and improve the cleanliness of the indoor air.

[0204] For example, the purification component 11 is installed inside the fresh air cavity V012, located at the axial air inlet end of the fresh air fan 6. The purification component 11 is connected to the second volute 82, which facilitates the assembly of the purification component 11 and prevents it from interfering with the fresh air fan 6. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air cavity V012 from the fresh air inlet 801, and allows the outdoor air entering the fresh air cavity V012 to pass through the purification component 11, then enter the volute cavity V011, and enter the room from the fresh air outlet 802.

[0205] In this way, the fresh airflow can blow almost vertically over the purification component 11, further reducing the consumption of fresh air intake and thus increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in cooling mode, causing condensation to form in the fresh air, the condensation can remain on the purification component 11 as the air flows through it, further preventing water from being blown out when the fresh air device is venting.

[0206] In some embodiments not shown in the figure, the fresh air outlet 802 includes a first fresh air outlet and a second fresh air outlet, both of which are connected to the fresh air duct V01. Thus, outdoor air entering the volute cavity V011 enters the room through the first and second fresh air outlets.

[0207] In some embodiments of this application, such asFigure 11 As shown, the purifying member 11 includes a filter screen (not shown in the figure) covering the axial air vent 8211. The filter screen covers the entire air inlet end of the fresh air fan 6, and has a large coverage area and a large filtration area, thus having a good filtration effect. The provision of the filter screen helps to ensure sufficient contact area with the airflow, and has a light weight and low air flow noise. For example, the filter screen is a Hepa screen, thus having strong adsorption force and strong filtration effect on dust in the air.

[0208] In some embodiments of the present application, the filter screen is plate-shaped, so that the filter screen as a whole is thin and does not occupy too much space when placed in the bidirectional ventilation assembly.

[0209] In some embodiments of the present application, the filter screen is square-shaped, thus facilitating positioning and installation of the filter screen.

[0210] In some embodiments of the present application, the filter screen is a square screen, and the side length of the filter screen is greater than the diameter of the axial air vent 8211. The square screen is convenient to position when fixed, is not easy to shake after being fixed, and is easy to process, thus generating less waste. The side length of the filter screen is greater than the diameter of the axial air vent 8211, so that all the fresh air flowing into the axial air vent 8211 can flow through the filter screen, thus having high filtration cleanliness.

[0211] In some embodiments of the present application, with reference to Figure 10 , a part of the fresh air cavity V012 constitutes an empty cavity V0121, the empty cavity V0121 is located on the side of the purifying member 11 away from the fresh air fan 6, and the fresh air inlet 801 communicates with the empty cavity V0121.

[0212] For example, the purifying member 11 is arranged at a position close to the fresh air fan 6 in the fresh air cavity V012, and the part of the fresh air cavity V012 away from the fresh air fan 6 is the empty cavity V0121, i.e. the space between the face of the purifying member 11 and the inner surface of the fan cover 822 is the empty cavity V0121, so that the empty cavity V0121 is in a negative pressure state when the fresh air fan 6 operates, enabling the airflow to automatically flow into the empty cavity V0121 from the fresh air inlet 801, thus reducing the air flow resistance.

[0213] The empty cavity V0121 corresponds to an air inlet negative pressure cavity of the fresh air fan 6, and the provision of the air inlet negative pressure cavity has many advantages:

[0214] I. Improving the air inlet efficiency. For example, the provision of the negative pressure cavity increases the buffer space of the fresh air fan 6 on the air suction side, making it easier for the fresh air fan 6 to suck air, thus increasing the air inlet amount of the fresh air fan 6. Moreover, the presence of the negative pressure cavity enables the fresh air to be buffered and adjusted in the negative pressure cavity before entering the fresh air fan 6, thus reducing the fluctuation and turbulence of the fresh air flow, which is conducive to improving the air inlet stability of the fresh air fan 6. If there is no empty cavity V0121 and no buffer space, the flow resistance will increase, and the operating power consumption of the fresh air fan 6 will rise.

[0215] Second, optimize air flow distribution. For example, through the buffering and guiding of the negative pressure cavity, the air flow is guided to be sucked into the fresh air fan 6 along the axial direction.

[0216] Third, reduce air flow impact and absorb noise.

[0217] In this way, while improving the air intake amount of the fresh air device, the overall air intake reliability and stability are improved.

[0218] In some embodiments of the present application, with reference to Figure 11 , the fresh air volute 8 is further provided with a mounting port 803, and the purification component 11 is detachably assembled in the mounting port 803. In this way, when the purification component 11 is damaged or saturated, the purification component 11 can be disassembled for convenient maintenance or replacement.

[0219] For example, as shown in Figure 11 , the mounting port 803 is surrounded by the fan cover 822 and the second volute half 821, and in combination with Figures 10-11 , the purification component 11 is detachably assembled in the fresh air cavity V012 through the mounting port 803. In this way, the size of the mounting port 803 can be set larger to facilitate the installation of a larger size purification component 11. When the size of the mounting port 803 is larger, the mounting port 803 is surrounded by the fan cover 822 and the second volute half 821, and the fan cover 822 and the second volute half 821 respectively form open half-ports, which is convenient for processing or demolding and has low waste product rate.

[0220] In some embodiments of the present application, in combination with Figures 2-5 , Figure 11 , in the front-rear direction of the main body 1000, the mounting port 803 is located on the front side of the main body 1000, and the purification component 11 can be disassembled without interference from the pipes connected at the fresh air inlet 801 and the exhaust air outlet 902, which facilitates disassembly. For example, the front side of the casing 1 is provided with an openable panel 15, and when the panel 15 is opened or the panel 15 is turned upward, the mounting port 803 can be exposed, which facilitates the disassembly of the purification component 11.

[0221] It is also not excluded that in some schemes, the mounting port 803 is arranged at the bottom of the main body 1000.

[0222] In some embodiments of the present application, Figure 8 , Figure 10As shown, the second volute 82 is formed with a purification air inlet 804 for communicating with the room. The fresh air fan 6 rotates to enable the indoor air to enter the fresh air cavity V012 from the purification air inlet 804 to pass through the purification member 11 for purification, and enable the indoor air entering the fresh air cavity V012 to blow through the purification member 11 and then enter the volute cavity V011 and from the fresh air outlet 802 into the room. In this way, the indoor air can enter the fresh air duct V01 from the purification air inlet 804, pass through the purification member 11, and then enter the room from the fresh air outlet 802.

[0223] In this way, when the indoor air is polluted, the indoor air can be circulated and purified. In this way, the indoor air can be purified without introducing outdoor fresh air, thereby improving the cleanliness. Since no outdoor fresh air is introduced, the indoor air is not suddenly blown into the outdoor air without heat exchange, thereby avoiding the discomfort caused by the sudden change of indoor temperature.

[0224] In some embodiments of the present application, the purification air inlet 804 can be in communication with the heat exchange air inlet 101, and no connecting pipe is needed between the purification air inlet 804 and the heat exchange air inlet 101, thereby reducing the number of parts, reducing the occupied volume, and facilitating the layout.

[0225] In some embodiments of the present application, as shown in Figure 8 The purification air inlet 804 is located at the bottom of the second volute 82 and is arranged downward. It can be understood that the fresh air inlet 801 is located below the main body 1000, and the fresh air inlet 801 and the purification air inlet 804 are both located at the bottom of the fresh air volute and extend downward, which is convenient for processing and forming. Moreover, in use, one of them is opened. At this time, the fresh air inlet 801 and the purification air inlet 804 are both located at the bottom of the fresh air volute 8, which is convenient for centralized arrangement of the switch to select one of the air inlets to be opened, thereby facilitating the reduction of the number of switches.

[0226] In some embodiments, as shown in Figure 4 , Figure 8 The air inlet direction of the purification air inlet 804 is perpendicular to the length direction of the heat exchange fan 41. It can be understood that the air inlet direction of the purification air inlet 804 is perpendicular to the length direction of the heat exchange fan 41, the purification air inlet 804 is far away from the air inlet 901, thereby avoiding excessive air suction energy consumption caused by the close distance between the purification air inlet 804 and the air inlet 901. Moreover, the different directions of the purification air inlet 804 and the air inlet 901 help to expand the negative pressure area, help a large amount of indoor air to flow into the negative pressure area, and ensure the air volume of the exhaust air and the indoor fresh air.

[0227] In some embodiments of the present application, the fresh air inlet 801 is located below the main body 1000 in the height direction of the main body 1000. It can be understood that the fresh air inlet 801 needs to be connected to a pipeline to introduce outdoor air, which is referred to as a fresh air introduction pipe 83 herein. The fresh air introduction pipe 83 can be a part of the wall-mounted air conditioner 10000, or it can be a fresh air introduction pipe 83 configured by the user after purchasing the wall-mounted air conditioner 10000.

[0228] By arranging the fresh air inlet 801 below the main body 1000, the fresh air introduction pipe 83 can be connected to the fresh air inlet 801 from below, and the connection extends generally in the up-down direction rather than in the front-back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0229] The part of the fresh air volute structure enclosed by the fresh air volute part 121 and the first volute half 81 for mounting the fresh air fan 6 is circular, and the axis of the fresh air fan 6 extends in the length direction of the heat exchange fan 41, so that there is a space at the bottom of the front side and the rear side of the circle. This space can be used to arrange the fresh air inlet 801 to connect the fresh air introduction pipe 83, so that the connection between the fresh air introduction pipe 83 and the fresh air inlet 801 can be placed in this space without occupying additional space, so that the height of the main body 1000 can be controlled.

[0230] In some embodiments, the exhaust air outlet 902 is located below the main body 1000 in the height direction of the main body 1000. Similarly, the exhaust air outlet 902 needs to be connected to a pipeline to guide indoor air to the outside, which is referred to as an exhaust air outlet pipe. The exhaust air outlet pipe can be a part of the wall-mounted air conditioner 10000, or it can be an exhaust air outlet pipe configured by the user after purchasing the wall-mounted air conditioner 10000.

[0231] By arranging the exhaust air outlet 902 below the main body 1000, the exhaust air outlet pipe can be connected to the exhaust air outlet 902 from below, and the connection extends generally in the up-down direction rather than in the front-back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0232] The part of the exhaust air volute structure enclosed by the exhaust air volute portion 122 and the exhaust air volute half 9 for mounting the exhaust air fan 7 is circular, extends along the length direction of the heat exchange fan 41 based on the axis of the exhaust air fan 7, so that there is a free space on the front side and the rear side of the bottom, and based on the characteristics of the exhaust air fan 7 that air is taken in axially and discharged radially, the diffuser section of the exhaust air volute half 9 can be arranged in the up-down direction and can be placed in the free space on the front side or the rear side. The exhaust air outlet 902 is provided here to connect the exhaust air leading pipe, so that the connection between the exhaust air leading pipe and the exhaust air outlet 902 can be placed in the free space without occupying additional space, so that the height dimension of the main body 1000 can be controlled.

[0233] In some embodiments, the wall-mounted air conditioner 10000 can include a fresh air leading pipe connected to the fresh air inlet 801, an exhaust air leading pipe connected to the exhaust air outlet 902, as shown in Figures 1-2 The right side wall of the casing 1 is provided with a leading pipe first avoiding opening 104, and the left side wall of the casing 1 is provided with a leading pipe second avoiding opening 105. After the fresh air leading pipe 83 is connected to the fresh air inlet 801 from below the main body 1000, it is bent and extends horizontally to the left, and then extends out of the leading pipe second avoiding opening 105 on the left side wall of the casing 1, and then extends to the outside. After the exhaust air leading pipe is connected to the exhaust air outlet 902 from below the main body 1000, it is bent and extends horizontally to the right, and then extends out of the leading pipe first avoiding opening 104 on the right side wall of the casing 1, and then extends to the outside. The fresh air leading pipe and the exhaust air leading pipe are led out on different sides, which is convenient for leading out nearby.

[0234] In some embodiments, the wall-mounted air conditioner 10000 can include a fresh air leading pipe connected to the fresh air inlet 801, an exhaust air leading pipe connected to the exhaust air outlet 902, as shown in Figures 1-2 The right side wall of the casing 1 is provided with a leading pipe first avoiding opening 104. After the fresh air leading pipe is connected to the fresh air inlet 801 from below the main body 1000, it is bent and extends horizontally to the right, and then extends out of the leading pipe first avoiding opening 104 on the right side wall of the casing 1, and then extends to the outside. After the exhaust air leading pipe is connected to the exhaust air outlet 902 from below the main body 1000, it is bent and extends horizontally to the right, and then extends out of the leading pipe first avoiding opening 104 on the right side wall of the casing 1, and then extends to the outside. The fresh air leading pipe and the exhaust air leading pipe are led out on the same side, which is convenient for management.

[0235] The fresh air leading pipe and the exhaust air leading pipe are two independent pipe fittings, which help to separate the fresh air flow path and the exhaust air flow path, and there is no cross, reducing the risk of air leakage caused by mutual cross flow.

[0236] It can be understood that the main body 1000 is usually provided with a refrigerant pipe and a drain pipe at one end in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 with the compressor and the outdoor heat exchanger. The drain pipe is used to drain the condensate water generated in the wall-mounted air conditioner 10000.

[0237] The first avoiding opening 104 of the guide pipe is arranged on the side wall of the casing 1, and then the fresh air inlet pipe and the exhaust air outlet pipe are transversely arranged and then led out from the first avoiding opening 104 of the guide pipe, so that at least one of the fresh air inlet pipe and the exhaust air outlet pipe is arranged together with the drain pipe and the refrigerant pipe. In this way, the multiple pipes are covered by the outer beam pipe or the beam belt outside the multiple pipes arranged together, so that the multiple pipes have the appearance of one pipe, thereby reducing the number of connected pipes on the wall-mounted air conditioner 10000 after installation and simplifying the appearance, which is convenient for assembly and avoids the risk of multiple pipe collisions.

[0238] In some embodiments not shown in the drawings, the fresh air outlet 802 is located below the main body 1000 to guide the fresh air to flow forward and downward to the indoor. Thus, the air blown from the fresh air outlet 802 can be directly blown to the user.

[0239] In some embodiments not shown in the drawings, the fresh air outlet 802 can be arranged to blow air to the indoor through the heat exchange air outlet 102, so that it is not necessary to re-open the casing air outlet, thereby simplifying the machining process of the casing 1. In addition, the air outlet area of the fresh air outlet 802 is overlapped with the air outlet area of the heat exchange air outlet 102, which is beneficial to the mixing of the fresh air and the indoor air after heat exchange. On the one hand, the uniformity of the mixed fresh air in the indoor air is improved, and on the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, so that the temperature of the fresh air tends to the indoor temperature, thereby improving the air blowing comfort.

[0240] In some embodiments not shown in the drawings, the casing 1 is provided with a casing air outlet, and the casing air outlet is spaced apart from the heat exchange air outlet 102. The fresh air outlet 802 can blow air to the indoor through the casing air outlet. The casing air outlet can be correspondingly arranged below the casing 1.

[0241] Because the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air outlet 102 is positioned relatively low on the casing 1, the fresh air outlet 802 blows fresh air from below. This makes the air outlet area of ​​the casing close to, or even partially overlap with, the air outlet area of ​​the heat exchange air outlet 102. This facilitates the mixing of fresh air with the indoor air after heat exchange, improving the uniformity of the mixed fresh air in the indoor air. Furthermore, the fresh air can absorb the cold or heat from the indoor air after heat exchange, causing the fresh air temperature to approach the indoor temperature, thus improving airflow comfort. Simultaneously, the air outlet direction of the fresh air outlet 802 is opposite to the air inlet direction of the heat exchange air inlet 101. The fresh air blown out from the fresh air outlet 802 will not be drawn into the heat exchange air inlet 101, reducing the proportion of fresh air intake at the heat exchange air inlet 101. This results in a larger total airflow from the wall-mounted air conditioner 10000, improving the overall circulation efficiency of the indoor air.

[0242] In addition, the fresh air outlet 802 is located below the main body 1000, close to the people's activity space, making it convenient for people to observe the fresh air supply. This achieves a visual effect of fresh air supply, which helps to improve people's experience.

[0243] When the fresh air outlet 802 is located below the main body 1000, it is usually located on the front side below the main body 1000. This allows the fresh air to flow forward and downward, ensuring that the fresh air can reach the ground and also reach a sufficiently long distance.

[0244] In some embodiments of this application, the housing 1 has an air outlet grille to adjust the direction of fresh air flow.

[0245] In some embodiments of this application, such as Figures 1-4 As shown, the fresh air outlet 802 is located at the top of the main body 1000 to guide fresh air upwards into the room. When the wall-mounted air conditioner 10000 is in cooling mode, the air blown out from the fresh air outlet 802 can descend from top to bottom, thus giving the user a top-down shower breeze experience, making the user feel cooler and reducing the indoor temperature more quickly.

[0246] In some embodiments of this application, such as Figures 7-11 , Figures 17-19 As shown, the fresh air fan 6 includes a fresh air impeller 61 and fresh air blades 62. The fresh air blades 62 are located on the outer edge of the fresh air impeller 61 and extend along the axial direction of the fresh air impeller 61. The total axial thickness of the fresh air impeller 61 and the fresh air blades 62 is h1. Here, the fresh air impeller 61 on the fresh air fan 6 can be one or at least two distributed at intervals along the axial direction. Each fresh air impeller 61 can have only one ring of fresh air blades 62 on one side or one ring of fresh air blades 62 on each side. h1 is the maximum dimension of the fresh air fan 6 in the axial direction.

[0247] As shown in Figures 12-16 , Figure 18 , the exhaust fan 7 includes an exhaust wheel disc 71 and an exhaust blade 72, the exhaust blade 72 is located at the outer edge of the exhaust wheel disc 71, and the exhaust blade 72 extends along the axial direction of the exhaust wheel disc 71, and the total thickness of the exhaust wheel disc 71 and the exhaust blade 72 in the axial direction is h2. Here, the exhaust wheel disc 71 on the exhaust fan 7 can be one or at least two distributed along the axial direction. A set of exhaust blades 72 can be arranged on only one side of each exhaust wheel disc 71 in the axial direction, or a set of exhaust blades 72 can be arranged on both sides of each exhaust wheel disc 71. h2 is the maximum dimension of the exhaust fan 7 in the axial direction of the exhaust fan 7.

[0248] Wherein, h2 < h1. In this way, while ensuring that the fresh air volume is greater than the exhaust air volume, the axial thickness of the main part of the fresh air fan 7 is greater, so that the structural strength is greater, and a greater torque can be borne. While the exhaust fan 7 requires less air volume, the smaller axial thickness of the main part can appropriately reduce the exhaust air volume, while reducing the axial size of the bidirectional ventilation assembly.

[0249] In some embodiments of the present application, the fresh air fan 6 includes a fresh air wheel disc 61, which is coaxially arranged with the common motor 42 and fixedly connected with the transmission shaft 43. When the transmission shaft 43 rotates, it drives the fresh air wheel disc 61 to rotate, thereby realizing the rotation of the fresh air fan 6.

[0250] In some embodiments of the present application, the fresh air fan 6 includes a fresh air blade 62, which is used to stir air and generate airflow when the fresh air fan 6 rotates. The fresh air blade 62 includes a first fresh air blade 621, which extends from the fresh air wheel disc 61 towards the direction away from the heat exchange fan 41.

[0251] In some embodiments of the present application, the fresh air blade 62 further includes a second fresh air blade 622, which extends from the fresh air wheel disc 61 towards the direction close to the heat exchange fan 41. The fresh air fan 6 is a double-suction centrifugal fan, which is beneficial to improve the air suction volume.

[0252] In some embodiments of the present application, in the axial direction of the fresh air fan 6, the length h12 of the second fresh air blade 622 is less than the length h11 of the first fresh air blade 621. Here, the first fresh air blade 621 is towards the axial air inlet end, so the axial length of the first fresh air blade 621 is greater, which is beneficial to obtain a greater fresh air inlet volume by using the first fresh air blade 621. The use of a shorter second fresh air blade 622 is beneficial to realize the supplement of fresh air inlet. Moreover, the first fresh air blade 621 on the windward side is longer, which is beneficial to reduce noise while ensuring fresh air volume.

[0253] In some embodiments of the present application, the new air wheel disc 61 is formed with a wheel disc hole 612 which penetrates the new air wheel disc 61 along the axial direction of the new air fan 6. The side where the second new air blade 622 is located can suck in air from the side where the first new air blade 621 is located through the wheel disc hole 612.

[0254] In some embodiments of the present application, the distance from the wheel disc hole 612 to the center of the new air wheel disc 61 is less than the distance from the new air blade 62 to the center of the new air wheel disc 61. In this way, the wheel disc hole 612 can better realize the air communication between the two sides of the new air wheel disc 61, so that the side where the second new air blade 622 is located can suck in air from the side where the first new air blade 621 is located through the wheel disc hole 612 more quickly.

[0255] In some embodiments of the present application, the new air wheel disc 61 at least partially extends away from the heat exchange fan 41 to form a new air recess 611. In this way, the gravity center of the new air fan 6 can be adjusted to the middle, which is beneficial to improve the unbalance of the new air fan 6 during rotation.

[0256] In some optional embodiments of the present application, the new air fan 6 is a single-suction centrifugal fan with single-side air suction, which is simple in structure. In some embodiments of the present application, the exhaust fan 7 is a single-suction centrifugal fan with single-side air suction, which is simple in structure.

[0257] In some embodiments of the present application, the exhaust fan 7 is a double-suction centrifugal fan with double-side air suction, which is beneficial to improve the air suction volume.

[0258] In some embodiments of the present application, as shown in Figures 5-6 the outer diameter of the new air fan 6 is greater than the outer diameter of the heat exchange fan 41, so that the new air volume is not too small. For example, in an embodiment, the outer diameter of the new air fan 6 is 137 mm, and the outer diameter of the heat exchange fan 41 is 94 mm.

[0259] In some embodiments of the present application, as shown in Figures 5-6 the outer diameter of the exhaust fan 7 is greater than the outer diameter of the heat exchange fan 41, so that the exhaust air volume is not too small. For example, in an embodiment, the outer diameter of the exhaust fan 7 is equal to the outer diameter of the new air fan 6, and the outer diameter of the new air fan 6, the outer diameter of the exhaust fan 7 are both 137 mm, and the outer diameter of the heat exchange fan 41 is 94 mm.

[0260] In some embodiments of the present application, as shown in Figures 5-6 the outer diameter of the new air fan 6 is greater than the outer diameter of the exhaust fan 7. In this way, while ensuring that the new air volume is greater than the exhaust air volume, the main part of the new air fan 7 has a greater radial thickness, so that the structural strength is greater and can bear a greater torque.

[0261] In some embodiments, the air outlet direction of the air outlet 902 is downward, for example, the air outlet 902 is located at the rear side of the exhaust volute half 9, and the air outlet direction of the air outlet 902 is downward. In this way, when the exhaust air outlet 902 is connected with the exhaust air outlet pipe, the exhaust air outlet pipe will not make the wall-mounted air conditioner 10000 too long as a whole, and the exhaust air outlet 902 is left on the side of the exhaust volute half 9 close to the wall, which facilitates the formation of the main body 1000 into a shape of wide back and narrow front.

[0262] When the main body 1000 is formed into a shape of wide back and narrow front, the wider back is installed close to the wall, and people see the narrower front when observing the wall-mounted air conditioner 10000, which is conducive to creating a lighter and thinner impression of the wall-mounted air conditioner 10000. In this way, the thick and heavy feeling of the wall-mounted air conditioner 10000 can be reduced, and the oppressive feeling caused by the wall-mounted air conditioner 10000 installed on the wall can be reduced.

[0263] In some embodiments, as shown in Figures 2-4 , the wall-mounted air conditioner 10000 further comprises an end plate 31, the end plate 31 is located at one end of the indoor heat exchanger 2 away from the exhaust fan 7, and the end plate 31 is connected with the indoor heat exchanger 2, and the end plate 31 is used to install the indoor heat exchanger 2 on the base 3.

[0264] The wall-mounted air conditioner 10000 further comprises a heat exchanger outlet pipe 21, the heat exchanger outlet pipe 21 is connected with one end of the indoor heat exchanger 2 facing the exhaust fan 7.

[0265] Among them, in the length direction of the main body 1000, the common motor 42 at least partially overlaps with the heat exchanger outlet pipe 21. In this way, the total length of the common motor 42 and the heat exchanger outlet pipe 21 in the length direction of the main body 1000 can be saved.

[0266] In some embodiments of the present application, as shown in Figures 3-4 , the wall-mounted air conditioner 10000 further comprises an electric control box 13, the electric control box 13, the exhaust fan 7 and the common motor 42 are located at the same transverse end of the heat exchange fan 41, and the electric control box 13 is located at the side of the exhaust fan 7 away from the common motor 42. The electric control box 13 and the common motor 42 are located at the same transverse end of the heat exchange fan 41, so that the wire between the electric control box 13 and the common motor 42 is short, the reliability of the connection between the electric control box 13 and the common motor 42 is improved, and the messy and easy-to-break situation caused by the long wire is avoided.

[0267] In some embodiments of the present application, the air inlet 901 comprises a first air inlet 9011 and a second air inlet 9012, the first air inlet 9011 is arranged to face the common motor 42, and the second air inlet 9012 faces the electric control box 13. As shown in Figure 3 , Figures 12-13As shown, the air exhaust device has double-side air inlet, and the air volume is larger. The two sides of the air exhaust device are the public motor 42 and the electric control box 13 respectively, and the air flow can well cool the public motor 42 and the electric control box 13, which is beneficial to increase the service life and stability of the public motor 42 and the electric control box 13.

[0268] In some embodiments of the present application, as shown in Figures 1-2 As shown, the wall-mounted air conditioner 10000 further comprises a panel 15, one end of the panel 15 is pivotally connected with the shell 1, for example, the upper end of the panel 15 is pivotally connected with the shell 1. The panel 15 can rotate relative to the shell 1. When the panel 15 is rotated to the open state, the purification member 11 is exposed, and the user can disassemble the filter screen in the purification member 11. When the panel 15 is rotated to the closed state, the purification member 11 is blocked, at this time, the panel 15 is an appearance part, and the appearance of the wall-mounted air conditioner 10000 is neat.

[0269] In some embodiments of the present application, as shown in Figures 1-2 As shown, the wall-mounted air conditioner 10000 further comprises a baffle 16, the left and right ends of the baffle 16 are pivotally connected with the shell 1. The baffle 16 can rotate relative to the shell 1. When the baffle 16 is rotated to the open state, the heat exchange air outlet 102 is exposed, and the air outlet from the heat exchange air outlet 102 is facilitated. When the baffle 16 is rotated to the closed state, the heat exchange air outlet 102 is blocked, which prevents sundries, flying insects and the like from entering the interior of the wall-mounted air conditioner 10000 through the heat exchange air outlet 102 when the wall-mounted air conditioner 10000 is not working.

[0270] In some embodiments, as shown in Figure 11 As shown, the wall-mounted air conditioner 10000 further comprises a fresh air valve motor 1210, which is used to drive the fresh air valve 1220 to translate.

The fresh air motor body 1211 is installed outside the fresh air volute 8, so that the fresh air motor body 1211 does not occupy the internal space of the fresh air volute 8, and thus does not occupy the space of the fresh air duct V01, and further does not affect the air volume in the fresh air duct V01. The fresh air motor shaft 1212 is rotatably arranged in the fresh air motor body 1211, and at least partially extends into the fresh air volute 8, and the fresh air motor shaft 1212 is used to drive the fresh air valve 1220 to open or close the fresh air inlet 801. Specifically, the fresh air motor shaft 1212 is rotatable relative to the fresh air motor body 1211, and the fresh air motor shaft 1212 is rotatable to drive the fresh air valve 1220 to move, so as to open or close the fresh air inlet 801.

For details, refer to Figures 1-4 、 Figure 11 As shown, the moving direction of the fresh air valve 1220 is the front-back direction of the main body 1000, so that the space of the bidirectional ventilation assembly in the front-back direction of the main body 1000 can be fully utilized; the axial direction of the fresh air valve motor 1210 and the axial direction of the common motor 42 are both the left-right direction of the main body 1000, so that the fresh air motor shaft 1212 can drive the fresh air valve 1220 to move in the front-back direction.

[0273] In some embodiments, as shown in Figure 11 The air inlet direction of the fresh air inlet 801 is perpendicular to the axial direction of the fresh air valve motor 1210, and the moving direction of the fresh air valve 1220 is perpendicular to the air inlet direction of the fresh air inlet 801. Specifically, the air inlet direction of the fresh air inlet 801 is the upward direction, and the moving direction of the fresh air valve 1220 is the front-back direction of the main body 1000, so that the fresh air valve 1220 can open or close the fresh air inlet 801 in the shortest moving distance range, which is conducive to energy saving.

[0274] In some embodiments, as shown in Figure 11As shown, the wall-mounted air conditioner 10000 further comprises a fresh air transmission mechanism 1230, the fresh air valve motor 1210 and the fresh air valve 1220 are connected in transmission through the fresh air transmission mechanism 1230, the fresh air transmission mechanism 1230 comprises a fresh air gear 1231 and a fresh air rack 1232, the fresh air gear 1231 is located inside the fresh air volute 8, and the fresh air gear 1231 is coaxially arranged with the fresh air motor shaft 1212, the fresh air motor shaft 1212 drives the fresh air gear 1231 to rotate, the fresh air rack 1232 is fixed on the fresh air valve 1220, and the fresh air rack 1232 is fixed on the side of the fresh air valve 1220 facing the fresh air gear 1231, so as to facilitate the direct engagement of the fresh air gear 1231 and the fresh air rack 1232, the length direction of the fresh air rack 1232 is perpendicular to the axis direction of the common motor 42, the fresh air gear 1231 is engaged with the fresh air rack 1232, so that the fresh air valve motor 1210 drives the fresh air valve 1220 to translate in the length direction of the fresh air rack 1232 when the fresh air gear 1231 rotates.

When the fresh air gear 1231 rotates, it drives the fresh air rack 1232 to move along the length direction of the fresh air rack 1232, and the fresh air rack 1232 drives the fresh air valve 1220 to move synchronously when the fresh air rack 1232 moves.

[0276] Optionally, the fresh air rack 1232 and the fresh air valve 1220 can be connected by bolt assembly, welding, bonding and the like; or optionally, the fresh air rack 1232 can be integrally formed with the fresh air valve 1220, which can reduce the assembly steps between the fresh air rack 1232 and the fresh air valve 1220 and reduce the number of parts.

The part of the fresh air motor shaft 1212 extending into the inside of the second volute 82 is used to drive the fresh air valve 1220 to act, so as to open or close the fresh air inlet 801.

[0279] In some embodiments, the fresh air motor body 1211 is mounted on the fan cover 822. Specifically, the fresh air motor body 1211 is mounted on the outside of the fan cover 822, without occupying the space inside the fan cover 822 and without affecting the air volume inside the fan cover 822.
