Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly to a wall-mounted air conditioner. Background Art

[0002] With the progress of technology and the improvement of people's living standards, air conditioners have gradually entered people's lives and become an indispensable item in people's work and life.

[0003] An air conditioner includes an indoor unit and an outdoor unit, which are respectively installed indoors and outdoors and are connected by corresponding pipelines and electric wires. Usually, in order to improve indoor air quality, the air conditioner also has a fresh air device and an exhaust device for ventilation. In related technologies, each of the fresh air device and the exhaust device requires a motor for driving, resulting in a large overall structure and an increase in cost. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the related technologies. For this purpose, some embodiments of the utility model provide a wall-mounted air conditioner, which can share the same motor for the fresh air fan and the exhaust fan while realizing simultaneous exhaust and air intake indoors, capable of reducing the overall size and saving costs.

[0005] The wall-mounted air conditioner according to some embodiments includes: a main body. The main body includes: a housing, an accommodation cavity is formed inside the housing, and a heat exchange air inlet and a heat exchange air outlet are formed on the housing; a base, disposed in the accommodation cavity, on which a volute tongue air duct is formed; a heat exchange fan, disposed in the volute tongue air duct; a first motor, disposed in the accommodation cavity and located at one end in the length direction of the heat exchange fan, for driving the heat exchange fan to rotate so that air can perform heat exchange between the inside of the air conditioner and the indoor space.

[0006] The wall-mounted air conditioner further includes: a second motor, disposed in the accommodation cavity and located at the other end in the length direction of the heat exchange fan, the second motor is an outer rotor motor, and the second motor includes: a stator part, on which a wound coil is provided; a rotor part, in the radial direction of the stator part, the rotor part is disposed around the outside of the stator part; a motor housing, the motor housing is fixedly connected to the rotor part; an output shaft, the output shaft is fixedly connected to the motor housing.

[0007] Wherein, the second motor is located between the fresh air fan and the heat exchange fan.

[0008] The wall-mounted air conditioner further includes: a fresh air fan, the fresh air fan is a centrifugal fan with axial air intake and radial air outlet, and the fresh air fan is fixedly connected to the output shaft of the second motor.

[0009] The wall-mounted air conditioner further includes: an exhaust fan, which is a centrifugal fan with axial air intake and radial air outlet. The exhaust fan is sleeved on the radial outer side of the motor housing and is fixedly connected to the motor housing.

[0010] The exhaust fan is located between the fresh air fan and the heat exchange fan. When the second motor is in the working state, it drives the fresh air fan and the exhaust fan to rotate synchronously. The fresh air fan and the exhaust fan share the same motor, which can reduce the overall size and save costs.

[0011] The wall-mounted air conditioner further includes: a fresh air volute. A fresh air duct is formed inside the fresh air volute. The fresh air fan is installed inside the fresh air volute. A fresh air inlet and a fresh air outlet are formed on the fresh air volute. When the fresh air fan rotates, outdoor air can enter the fresh air volute from the fresh air inlet, and the outdoor air entering the fresh air volute can enter the room from the fresh air outlet.

[0012] The wall-mounted air conditioner further includes: an exhaust volute, which is located on the side of the fresh air volute facing the second motor. An exhaust duct is formed inside the exhaust volute. The exhaust fan is installed inside the exhaust volute. An exhaust inlet and an exhaust outlet are formed on the exhaust volute. When the exhaust fan rotates, indoor air can enter the exhaust volute from the exhaust inlet, and the indoor air entering the exhaust volute can be discharged to the outside from the exhaust outlet.

[0013] The wall-mounted air conditioner according to some embodiments can improve the cleanliness of the inhaled fresh air while realizing simultaneous exhaust and air intake in the room.

[0014] The second motor, the fresh air fan, the exhaust fan, the fresh air volute and the exhaust volute constitute a two-way ventilation component. By using an outer rotor motor for the second motor, sleeving the exhaust fan on the radial outer side of the motor housing, partially embedding the second motor in the motor housing in the exhaust fan, and partially embedding it in the fresh air fan on the output shaft, the second motor almost overlaps with the exhaust fan and the fresh air fan in the length direction of the heat exchange fan, so that the parts of the exhaust fan and the fresh air fan located outside the second motor in the axial direction are less, making the overall axial dimension of the two-way ventilation component close to the axial dimension of the second motor, thereby controlling the length dimension of the main body.

[0015] The main body of the second motor is located inside the exhaust fan rather than the fresh air fan, which can leave more air flow space for the fresh air duct, facilitating the intake of fresh air, making the exhaust air volume less than the fresh air volume, and reducing the loss of indoor cooling or heating capacity. Since the second motor uses an external rotor motor that can adapt to scenarios such as low-speed high torque and direct drive, a speed reducer does not need to be set, and the exhaust fan can be directly sleeved on the radial outside of the motor housing. This not only avoids the increase in the overall axial dimension by the speed reducer but also avoids the increase in the difficulty of structural layout by the speed reducer. Just by fixedly connecting the exhaust fan to the motor housing and connecting the fresh air fan to the output shaft of the second motor, the exhaust fan and the fresh air fan can be arranged coaxially and stacked, rotating synchronously and maintaining a small gap without a large interval.

[0016] The exhaust fan is located between the fresh air fan and the heat exchange fan. In other words, the exhaust fan is closer to the heat exchange fan than the fresh air fan. When the wall-mounted air conditioner is cooling or heating, the heat exchange fan operates to drive the indoor air entering the housing from the heat exchange air inlet to flow through the indoor heat exchanger. The exhaust fan is close to the heat exchange fan, and the air inlet end of the exhaust fan is close to the air inlet end of the heat exchange fan. The exhaust fan can suck air from the air inlet end of the heat exchange fan. That is to say, when the exhaust fan rotates, it can suck the indoor air sucked into the housing from the heat exchange air inlet to the exhaust fan, so there is no need to separately open a hole on the housing to supply air to the exhaust fan, thereby reducing the number of openings on the housing, simplifying the processing and manufacturing process of the housing, and increasing the aesthetic degree. In addition, the heat exchange air inlet is generally set relatively large, so the amount of indoor air sucked into the housing through the heat exchange air inlet is large, making the air volume reaching the exhaust fan also large, and accelerating the exhaust efficiency. In addition, the fresh air fan is arranged on the side of the exhaust fan away from the heat exchange fan. When there is condensate on the indoor heat exchanger near the heat exchange fan, the condensate is not likely to reach the fresh air fan, reducing the risk of water accumulation and bacteria breeding at the fresh air fan.

[0063] Some embodiments of the present utility model provide a wall-mounted air conditioner 10000.

[0064] 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 pipelines to transmit refrigerant. The indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 41.

[0065] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling member. The compressor, the outdoor heat exchanger, the throttling member, and the indoor heat exchanger 2 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with air through the outdoor heat exchanger and the indoor heat exchanger 2 respectively to achieve the cooling mode or the heating mode of the air conditioner.

[0066] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0067] The outdoor heat exchanger is configured to exchange heat between the outdoor air and the refrigerant flowing in the outdoor heat exchanger. For example, the outdoor heat exchanger operates as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor dissipates heat to the outdoor air through the outdoor heat exchanger and condenses. The outdoor heat exchanger operates as an evaporator in the heating mode of the air conditioner, so that the decompressed refrigerant absorbs the heat of the outdoor air through the outdoor heat exchanger and evaporates.

[0068] In some embodiments, the outdoor heat exchanger may include heat exchange fins to increase the contact area between the outdoor air and the refrigerant flowing in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0069] The outdoor fan is configured to suck external air into the outdoor unit and send the outdoor air that has exchanged heat with the outdoor heat exchanger to the outside. The outdoor fan provides power for the flow of the outdoor air.

[0070] The throttling member is connected between the outdoor heat exchanger and the indoor heat exchanger 2. The throttling member is used to adjust the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2 to adjust the refrigerant flow rate flowing between the outdoor heat exchanger and the indoor heat exchanger 2. The flow rate and pressure of the refrigerant flowing 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. The throttling member can be a throttle tube, an electronic valve, etc. When the throttling member is an electronic valve, the opening degree of the throttling member is adjustable to adjust the flow rate and pressure of the refrigerant flowing through the throttling member.

[0071] In some solutions, the air conditioner may include a four-way valve. The four-way valve is connected in the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner executes the cooling mode or the heating mode.

[0072] The indoor heat exchanger 2 is configured to exchange heat between the indoor air and the refrigerant flowing through the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 may include heat exchange fins to increase the contact area between the indoor air and the refrigerant flowing through the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0073] The heat exchange fan 41 is configured to suck the indoor air into the indoor unit and send the indoor air that has exchanged heat with the indoor heat exchanger 2 back into the room, and the heat exchange fan 41 provides power for the flow of the indoor air.

[0074] The air conditioner may include a control device, which is mainly used to control the operating frequency of the compressor and the opening degree of the throttle member. 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 to the compressor, the throttle member, the motor driving the outdoor fan to rotate, and the first motor 42 driving the heat exchange fan 41 to rotate through data lines to transmit communication information.

[0075] The control device includes a processor, and the processor may include a central processing unit (CPU), a microprocessor, and an application specific integrated circuit (ASIC), and may be configured to perform the corresponding operations described in the control device when the processor executes a program stored in a non-transitory computer-readable medium coupled to the control device.

[0076] The non-transitory computer-readable storage medium may include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a thumb drive).

[0077] Currently, most wall-mounted air conditioners are limited by their volume and weight, and the functions they can achieve are relatively limited. Usually, they can only cool or heat the indoor air. After the user has turned on the air conditioner for a long time, if they feel that the indoor air is dirty and stuffy and need to open the window for ventilation, it is not only troublesome to operate, but also the indoor cold air or warm air will quickly escape from the window during the window-opening period, affecting people's comfort.

[0078] Some fresh air air conditioners in the related art suck fresh air from the outside through a fresh air device and discharge the indoor air through an exhaust device. However, due to factors such as unreasonable structural design, the quality of the fresh air blown into the room by the fresh air device is low, and the purpose of improving the indoor air quality cannot be achieved.

[0079] To solve the above problems, some embodiments of the present utility model provide a wall-mounted air conditioner 10000. By adjusting and setting the structures and relative positions of components such as the second motor, the exhaust fan, and the motor housing, it is possible to improve the cleanliness of the inhaled fresh air while achieving simultaneous exhaust and intake of air in the room.

[0080] For example, the wall-mounted air conditioner 10000 is an indoor unit. The wall-mounted air conditioner 10000 is usually installed on a wall, for example, it can be installed in the upper area of an indoor wall.

[0081] The wall-mounted air conditioner 10000 according to some embodiments will be described below with reference to the accompanying drawings.

[0082] The wall-mounted air conditioner 10000 of some embodiments, as Figure 1 and Figure 2 shown, includes: a main body 1000.

[0083] The main body 1000 includes: a housing 1. As Figure 20 shown, an accommodation cavity V1 is formed inside the housing 1, and a heat exchange air inlet 101 and a heat exchange air outlet 102 are formed on the housing 1. The housing 1 can play a protective role and constitute the overall external shape structure of the wall-mounted air conditioner 10000.

[0084] Generally, the housing 1 is an elongated housing as a whole, and the length direction of the housing 1 is arranged along the horizontal direction, that is, the housing 1 is installed horizontally on the wall. In actual products, in order to drain condensed water, in some embodiments, the housing 1 is installed horizontally on the wall as a whole and forms a small angle with the horizontal plane.

[0085] Referring to Figure 3 and Figure 4 , the main body 1000 further includes: an indoor heat exchanger 2, and the indoor heat exchanger 2 is disposed in the accommodation cavity V1. As described above, the indoor heat exchanger 2 is a part of the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger 2, which is used to cool or heat the air flowing through the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 usually extends along the length direction of the housing 1.

[0086] 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-like structure extending along the length direction.

[0087] Referring to Figure 3 and Figure 4, the main body 1000 further includes a base 3, and the base 3 is disposed in the accommodation cavity V1. The base 3 is an installation and support structure inside the main body 1000, and the indoor heat exchanger 2 can be installed on the base 3. For example, a volute tongue air duct V03 is formed on the base 3. After the indoor air enters the casing 1, the flow direction is guided through the volute tongue air duct V03, ensuring that the resistance suffered by the indoor air when flowing through the indoor heat exchanger 2 is small.

[0088] Referring to Figure 4 , the main body 1000 further includes: a heat exchange fan 41, and the heat exchange fan 41 is disposed in the volute tongue air duct V03.

[0089] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which has low noise and a large air volume, and the air outlet speed of the cross-flow fan is relatively evenly distributed along the axial direction of the cross-flow fan, which is beneficial to increasing the air supply distance and the air supply range. Moreover, when a cross-flow fan is adopted and the cross-flow fan is arranged along the length direction of the heat exchange fan 41, it is beneficial to drive the air flow to flow through the entire indoor heat exchanger 2, ensuring the balance of the heat exchange efficiency at each position of the indoor heat exchanger 2.

[0090] Referring to Figure 4 , the main body 1000 further includes: a first motor 42, and the first motor 42 is disposed in the accommodation cavity V1. The first motor 42 is used to drive the heat exchange fan 41 to rotate, so that air can perform heat exchange between the inside of the air conditioner and the indoor space.

[0091] By providing a heat exchange air outlet 102 and a heat exchange air inlet 101 in the casing 1, when the heat exchange fan 41 operates, the indoor air can be sucked into the casing 1 from the heat exchange air inlet 101. After the indoor air exchanges heat with the indoor heat exchanger 2, the heat-exchanged air is sent to the indoor from the heat exchange air outlet 102.

[0092] Thus, the adjustment of the indoor environmental temperature can be realized. The indoor heat exchanger 2 can be used as an evaporator to provide a cooling air flow towards the indoor space from the heat exchange air outlet 102, or the indoor heat exchanger 2 can be used as a condenser to provide a heating air flow towards the indoor space from the heat exchange air outlet 102.

[0093] 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 air can be introduced from above and discharged from below.

[0094] For example, the height direction of the main body 1000 is the up and down direction.

[0095] It can be understood that the main body 1000 is usually installed on the wall. To avoid interfering with people's daily lives, the position where the main body 1000 is hung is usually relatively high. By setting the main body 1000 to blow out the heat exchange air from below, the blown heat exchange air is not easily blocked by the roof or the ground. In this way, the resistance consumed during the blowing process of the heat exchange air is small, and the air supply range is wide, so that the heat exchange air can flow to the entire indoor space as soon as possible, improving the heat exchange efficiency.

[0096] Referring to Figure 1 and Figure 2 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102. The heat exchange air inlet 101 can intake air from above, which can avoid intake air from the heat exchange air outlet 102, preventing the heat exchange air from being directly sucked into the heat exchange air inlet 101 after being blown out from the heat exchange air outlet 102, and reducing the process of the heat exchange air idling without participating in indoor heat exchange.

[0097] In some embodiments, the heat exchange air inlet 101 is located at the top of the casing 1, that is, in an area that is not visible to the user, hiding the heat exchange air inlet 101 can improve the aesthetic appearance of the wall-mounted air conditioner 10000.

[0098] In some embodiments, the heat exchange air outlet 102 is located directly in front of the casing 1, that is, the heat exchange air outlet 102 blows air towards the front side of the main body 1000.

[0099] It can be understood that the side where the main body 1000 is connected to the wall is usually referred to as the back or the rear side, and the side opposite to the rear side is referred to as the front side. Therefore, when the heat exchange air outlet 102 is located directly in front of the casing 1, the air outlet is away from the wall, and the blowing resistance is small, and the air supply range is wide.

[0100] 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, while the heat exchange air blown out from the heat exchange air outlet 102 flows forward, it will also flow downward, so that after the heat exchange air is sent to a certain distance, it can sink and fall on people or objects on the ground, enabling people or objects on the ground to be in a suitable indoor environment as soon as possible.

[0101] In some embodiments, the heat exchange fan 41 is located on the side of the indoor heat exchanger 2 that is far from the heat exchange air inlet 101. It can be understood that the heat exchange fan 41 is a power driving part that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotating, and is also a power driving part for air supply.

[0102] The heat exchange fan 41 is placed on one side of the indoor heat exchanger 2 away from the heat exchange air inlet 101, which can evenly distribute the aerodynamic force generated when the heat exchange fan 41 rotates. Part of it is distributed to the air inlet side, so that when the inhaled air flows into the volute tongue air duct V03, it can overcome the air resistance generated by the indoor heat exchanger 2. The other part is distributed to the air supply side, so that when the heat-exchanged air is blown out from the heat exchange air outlet 102, the conveying distance is relatively long.

[0103] In some embodiments, as Figure 4 shown, the first motor 42 is located at one end of the heat exchange fan 41 in the length direction. In this way, it is convenient to install and maintain the first motor 42, and the overall body 1000 does not need to become too high and thick due to the setting of the first motor 42. Here, the height direction of the body 1000 is the same as the up and down direction, and the thickness direction of the body 1000 is the same as the front and back direction.

[0104] It can be understood that the wall-mounted air conditioner 10000 is generally of a long strip structure, and the length direction of the heat exchange fan 41 is the same as the length direction of the body 1000, both being Figures 1 - 2 、 Figure 19 the left and right directions shown in

[0105] In some embodiments, as Figure 8 shown, the wall-mounted air conditioner 10000 further includes a second motor 5. The second motor 5 is disposed in the accommodation cavity V1 and is located at the other end of the heat exchange fan 41 in the length direction.

[0106] In this way, the first motor 42 and the second motor 5 are located at both ends of the heat exchange fan 41 in the length direction. On the one hand, the two motors are separated and far apart, and the mutual electromagnetic interference is small. On the other hand, the two motors are arranged at both ends of the heat exchange fan 41 in the length direction, rather than in the thickness or height direction of the body 1000, making the shape of the body 1000 of the wall-mounted air conditioner 10000 slender, with a slender, thin and light appearance.

[0107] Referring to Figure 9 and Figure 10 , the second motor 5 includes: a stator part 51 and a rotor part 52. The stator part 51 and the rotor part 52 are the main parts of the second motor 5. The stator part 51 has a wound coil. After the coil is energized with alternating current, an alternating magnetic field is generated, and the rotor part 52 generates induction and rotates in the alternating magnetic field.

[0108] For example, the rotor part 52 can be a magnetic ring or a magnetic tile. For example, when the rotor part 52 is a magnetic ring, the magnetic leakage loss can be reduced, the magnetic flux can be enhanced, and the power output efficiency of the second motor 5 can be improved. Moreover, when a magnetic ring is used, the magnetic field distribution is uniform, the anti-interference performance is good, and the mechanical precision is higher.

[0109] The second motor 5 is an outer-rotor motor. In the radial direction of the stator part 51, the rotor part 52 is arranged around the outside of the stator part 51. The second motor 5 selects an outer-rotor motor. Not only is the structure of the outer-rotor motor simple, but also since the rotor part 52 is arranged around the outside of the stator part 51 in the radial direction of the stator part 51, the diameter size of the rotor part 52 is large, and a larger torque can be obtained. It can be used in scenarios such as low-speed high-torque and direct drive. That is, when the second motor 5 outputs power outward, a speed reducer does not need to be set to reduce speed and increase torque, saving the space occupied by the speed reducer.

[0110] In addition, the rotor part 52 is located on the radial outside of the stator part 51, with a relatively large heat dissipation area and good heat dissipation performance, which is beneficial to the stable operation of the second motor 5. And after being arranged in this way, the diameter size of the second motor 5 can be controlled to be relatively small, without occupying the space of the air flow channel.

[0111] Refer to Figure 9 and Figure 10 , the second motor 5 further includes: a motor housing 53, and the motor housing 53 can support and protect the main part of the second motor 5.

[0112] The motor housing 53 is fixedly connected to the rotor part 52, and the motor housing 53 rotates synchronously with the rotor part 52. In this way, the rotor part 52 can be fixed through the motor housing 53, which is convenient for connecting with external structures.

[0113] The second motor 5 further includes: an output shaft 532, the output shaft 532 is fixedly connected to the motor housing 53, and one end of the output shaft 532 extends along the axial direction of the motor housing 53 toward the side away from the heat exchange fan 41. That is to say, the main part of the second motor 5 is separated from the indoor heat exchanger 2 and the heat exchange fan 41 by a certain distance, reducing the vibration transmitted from the operation of the second motor 5 to the indoor heat exchanger 2 and the heat exchange fan 41.

[0114] Refer to Figure 8 , the wall-mounted air conditioner 10000 further includes: a fresh air fan 6, the fresh air fan 6 is a centrifugal fan with axial air inlet and radial air outlet, the fresh air fan 6 is located on the side of the heat exchange fan 41 away from the first motor 42, and the fresh air fan 6 is fixedly connected to the output shaft 532 of the second motor 5.

[0115] Refer to Figure 8 , the wall-mounted air conditioner 10000 further includes: an exhaust fan 7, the exhaust fan 7 is a centrifugal fan with axial air inlet and radial air outlet, the exhaust fan 7 is sleeved on the radial outside of the motor housing that 53, and the exhaust fan 7 is fixedly connected to the motor housing 53. For example, when the second motor 5 is in the working state, it drives the fresh air fan 6 and the exhaust fan 7 to rotate synchronously.

[0116] The characteristics of the centrifugal fan itself include a compact structure, a large air volume, and low noise. Moreover, when the rotational speed decreases, the fan noise decreases significantly. Therefore, for the fresh air fan 6 and the exhaust fan 7, selecting a centrifugal fan with a smaller size can meet the requirement of a large air volume. The centrifugal fan has small vibration noise and is not prone to resonance with the indoor heat exchanger 2, which is beneficial to reducing the overall vibration and noise of the wall-mounted air conditioner 10000.

[0117] Both the fresh air fan 6 and the exhaust fan 7 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 takes in air axially and discharges air radially, and the exhaust fan 7 takes in air axially and discharges air radially. The fresh air fan 6 and the exhaust fan 7 take in air from two ends far away from each other, and then the fresh air and the exhaust air are driven to discharge air radially after passing through the drive. The flow paths of the fresh air and the exhaust air do not need to overlap axially and do not need to cross. This helps to reduce the avoidance corner design of the fresh air and exhaust air paths, reduce wind resistance and energy consumption, ensure the air volume, and reduce noise.

[0118] In some embodiments, referring to Figure 8 , the exhaust fan 7 is located between the fresh air fan 6 and the heat exchange fan 41. In other words, the exhaust fan 7 is closer to the heat exchange fan 41 than the fresh air fan 6. 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. The exhaust fan 7 is close to the heat exchange fan 41, and the air inlet end of the exhaust fan 7 is relatively close to the air inlet end of the heat exchange fan 41. The exhaust fan 7 can suck air from the air inlet end of the heat exchange fan 41. That is to say, when the exhaust fan 7 rotates, it can suck the indoor air sucked into the casing 1 from the heat exchange air inlet 101 to the exhaust fan 7, so that there is no need to separately open a hole in the casing 1 to supply air to the exhaust fan 7. Thereby, the number of openings in the casing 1 is reduced, the processing and manufacturing process of the casing 1 is simplified, and the aesthetic degree is increased. In addition, the heat exchange air inlet 101 is generally set to be relatively large, so the amount of indoor air sucked into the casing 1 through the heat exchange air inlet 101 is large, so that the air volume reaching the exhaust fan 7 is also large, accelerating the exhaust efficiency.

[0119] In addition, in some embodiments, the fresh air fan 6 is arranged on the side of the exhaust fan 7 away from the indoor heat exchanger 2. When there is condensed water on one side of the indoor heat exchanger 2, the condensed water is not likely to reach the fresh air fan 6, reducing the risk of water accumulation and bacteria breeding at the fresh air fan 6.

[0120] Referring to Figures 5 - 8, the wall-mounted air conditioner 10000 further includes: a fresh air volute 8. A fresh air duct V01 is formed inside the fresh air volute 8. The fresh air fan 6 is installed inside the fresh air volute 8. A fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air volute 8. When the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802.

[0121] Referring to Figures 5 - 8 , the wall-mounted air conditioner 10000 further includes: an exhaust volute 9. The exhaust volute 9 is located on the side of the fresh air volute 8 facing the second motor 5. An exhaust duct V02 is formed inside the exhaust volute 9. The exhaust fan 7 is installed inside the exhaust volute 9. An exhaust inlet 901 and an exhaust outlet 902 are formed on the exhaust volute 9. When the exhaust fan 7 rotates, indoor air can enter the exhaust volute 9 from the exhaust inlet 901, and the indoor air entering the exhaust volute 9 can be discharged to the outside from the exhaust outlet 902.

[0122] In some embodiments, the fresh air volute 8 and the fresh air fan 6 constitute a fresh air device. The fresh air fan 6 is arranged inside the fresh air duct V01 and is used to drive the air flow to be sucked in from the fresh air inlet 801 and discharged to the room through the fresh air outlet 802. The operation of the fresh air fan 6 provides the power for the fresh air flow.

[0123] Thus, by setting the cooperation of the fresh air duct V01 and the fresh air fan 6, when the air in the room is relatively dirty or the air quality is poor, the relatively fresh outdoor air can be driven into the indoor environment by the fresh air fan 6 to improve the indoor air flow environment.

[0124] In some embodiments, the exhaust volute 9 and the exhaust fan 7 constitute an exhaust device. The exhaust fan 7 is arranged inside the exhaust duct V02 and is used to drive the air flow to be sucked in from the exhaust inlet 901 and discharged from the exhaust outlet 902 out of the room. The operation of the exhaust fan 7 provides the power for the dirty air flow.

[0125] Thus, by setting the cooperation of the exhaust duct V02 and the exhaust fan 7, when the air in the room is relatively dirty or the air quality is poor, the dirty air flow in the indoor space can be sucked away and discharged by the exhaust fan 7. After the indoor air volume is reduced in this way, fresh air will be inhaled from the outside or from other rooms through doors and windows, etc., to reduce the dirtiness of the indoor air.

[0126] The second motor 5, the fresh air fan 6, the exhaust fan 7, the fresh air volute 8 and the exhaust volute 9 constitute a two-way ventilation component. The two-way ventilation component is arranged inside the main body 1000. The two-way ventilation component can provide fresh air for the room and can discharge the indoor air to the outside.

[0127] It should be noted that in the wall-mounted air conditioner 10000, the operation mode of the two-way ventilation component can be set according to actual usage requirements.

[0128] In some embodiments, the two-way ventilation component can operate in the fresh air mode and the exhaust mode simultaneously, that is, the fresh air duct V01 and the exhaust duct V02 can be opened simultaneously. While the indoor polluted air flows towards the outdoor space, the fresh air outdoors can also enter the indoor space. Through the combination of one-in and one-out air flow driving, it is beneficial to increase the improvement efficiency of the air flow in the indoor space, so as to meet the user's needs in time when the user urgently needs to discharge or update the indoor air.

[0129] Moreover, since while discharging the indoor air to the outside, fresh outdoor air is supplemented into the indoor, keeping the indoor air volume sufficient and making it easier to suck away the indoor air. For example, when there are irritating gases (such as gases released by home improvement materials), gas leaks of gas or other gases indoors, the two-way ventilation component can be set to operate in the fresh air mode and the exhaust mode simultaneously to achieve rapid ventilation. And compared with the design of simply introducing fresh air in the conventional fresh air structure, the two-way ventilation component in some embodiments has a larger purification flow rate per unit time, higher ventilation efficiency and better purification effect.

[0130] Moreover, during ventilation, it avoids the situation of too rapid ventilation like directly opening a window, which may cause a drastic change in the indoor temperature and discomfort to the indoor personnel due to sudden temperature rise or fall. And the position of the main body 1000 is relatively high, and the ventilation position will not cause discomfort due to being too close to people.

[0131] In some embodiments, the two-way ventilation component can operate in the fresh air mode and the exhaust mode alternatively, that is, when the two-way ventilation component turns on the fresh air mode, the exhaust mode is shut down. At this time, only the fresh air duct V01 is ventilated, and the exhaust duct V02 is not ventilated. Or when the two-way ventilation component turns on the exhaust mode, the fresh air mode is shut down. At this time, the fresh air duct V01 is not ventilated, and the exhaust duct V02 is ventilated.

[0132] In some embodiments, a two-way ventilation component is provided in the wall-mounted air conditioner 10000, such as Figure 8 shown, the two-way ventilation component includes: a second motor 5, a fresh air fan 6, an exhaust fan 7, a fresh air volute 8 and an exhaust volute 9.

[0133] In some embodiments, the second motor 5 is an external rotor motor. The second motor 5 includes: a stator part 51, a rotor part 52, a motor housing 53 and an output shaft 532. The stator part 51 has a wound coil. Radially of the stator part 51, the rotor part 52 is arranged around the outside of the stator part 51. The motor housing 53 is fixedly connected to the rotor part 52. The output shaft 532 is fixedly connected to the motor housing 53, and one end of the output shaft 532 extends axially along the motor housing 53 towards the side away from the heat exchange fan 41.

[0134] In some embodiments, the second motor 5 is located at an end of the heat exchange fan 41 in the length direction, and the axial direction of the second motor 5 is arranged along the length direction of the heat exchange fan 41. The second motor 5 is a common power source for the fresh air device and the exhaust air device of the two-way ventilation assembly. To ensure the operation of the fresh air device and the exhaust air device, the second motor 5 needs to have sufficient operating power to drive a sufficient amount of air flow. Based on the power requirement of the second motor 5, the second motor 5 needs to be of a sufficiently large size.

[0135] In some embodiments, on the premise that the size parameters of the second motor 5 are generally determined, when arranging the fresh air device and the exhaust air device at this time, what is considered is how to utilize the space where the second motor 5 is located and occupy as little additional space as possible.

[0136] In some embodiments, both the fresh air fan 6 and the exhaust air fan 7 adopt centrifugal fans and are connected to the same motor. This not only saves the number of motors, reduces the overall size, and saves costs, but also keeps the two centrifugal fans arranged in a stacked manner along the axial direction of the second motor 5, that is, the two centrifugal fans are arranged in a stacked manner along the length direction of the heat exchange fan 41.

[0137] In some embodiments, the centrifugal fan itself is relatively flat in the axial direction. Stacking the fresh air fan 6 and the exhaust air fan 7 in this way can reduce the overall occupied axial dimension, so that the length of the main body 1000 does not need to be too long. Since the fresh air fan 6 and the exhaust air fan 7 are connected to the same motor and rotate synchronously, they are in step with each other and do not need to have too large a gap between them. The axial distance between the fresh air fan 6 and the exhaust air fan 7 can be arranged relatively close.

[0138] It should be noted that when referring to "axial direction", "radial direction", and "circumferential direction" in describing the internal structure of the two-way ventilation assembly, they are all based on the axial direction, radial direction, and circumferential direction of the motor, that is, the direction parallel to the extension direction of the output shaft 532 of the second motor 5 is the axial direction, the direction perpendicular to the extension direction of the output shaft 532 is the radial direction, and the direction around the output shaft 532 is the circumferential direction.

[0139] In the above solution, by using an outer rotor motor for the second motor 5, the exhaust air fan 7 is sleeved on the radial outside of the motor housing 53, a part of the second motor 5 in the motor housing 53 is embedded in the exhaust air fan 7, and a part of the output shaft 532 is embedded in the fresh air fan 6, so that the second motor 5 almost overlaps with the exhaust air fan 7 and the fresh air fan 6 in the length direction of the heat exchange fan 41, and the parts of the exhaust air fan 7 and the fresh air fan 6 located outside the second motor 5 in the axial direction are less, making the overall axial dimension of the two-way ventilation assembly close to the axial dimension of the second motor 5, so that the length dimension of the main body 1000 is controllable.

[0140] For example, the main body of the second motor 5 is located inside the exhaust fan 7 instead of the fresh air fan 6, which can leave more air flow space for the fresh air duct V01 and is beneficial to the intake of fresh air. It can be understood that when the wall-mounted air conditioner 10000 is in the cooling state, the fresh air device sucks fresh air from the outside to the inside, and the cold generated by the wall-mounted air conditioner 10000 can still remain indoors with little cold loss.

[0141] In some embodiments, the indoor air is discharged outdoors through the exhaust device. By setting the exhaust air volume to be less than the fresh air volume, the cold loss can be reduced. Therefore, squeezing the space of the exhaust duct V02 by the second motor 5 and leaving more space for the fresh air duct V01 is beneficial to ensuring a larger fresh air volume.

[0142] Moreover, since the second motor 5 uses an outer rotor motor that can adapt to scenarios such as low-speed high torque and direct drive, a speed reducer does not need to be set. The exhaust fan 7 can be directly sleeved on the radial outside of the motor housing 53. This not only avoids the speed reducer increasing the overall axial dimension but also avoids the speed reducer increasing the difficulty of structural layout. Just fixedly connecting the exhaust fan 7 to the motor housing 53 and connecting the fresh air fan 6 to the output shaft 532 of the second motor 5 can make the exhaust fan 7 and the fresh air fan 6 arranged coaxially and stacked, rotate synchronously and maintain a small gap without too large an interval. In this way, it also ensures that the overall axial dimension of the two-way ventilation component is close to the axial dimension of the second motor 5, and the length dimension of the main body 1000 is controllable.

[0143] In some embodiments, the fresh air device and the exhaust device are effectively integrated, enabling the two devices to rationally utilize their respective structural and space characteristics to complete a flat design. This not only reduces the overall size and weight of the two-way ventilation component, making the two-way ventilation component overall light and the air ducts not interfering with each other. The two-way ventilation component is arranged at one end in the length direction of the heat exchange fan 41. Compared with the main body without the two-way heat exchange component, only the lateral length is increased, and the height and thickness of the main body 1000 can generally remain unchanged or change little, making the main body 1000 thin and light in shape. When hung on the wall, it will not affect the indoor space layout too obtrusively and will not be difficult to fix due to excessive weight, reducing the risk of falling off the wall. The wall-mounted air conditioner 10000 as a whole is still a thin and light model, which is not only beautiful when hung on the wall but also has a controllable weight.

[0144] In some embodiments, as Figures 8 - 10 shown, a part of the output shaft 532 is located inside the stator portion 51, and the output shaft 532 is rotatably connected to the stator portion 51. In this way, the output shaft 532 can be supported by the stator portion 51, improving the axial and radial bending moment bearing capacity on the output shaft 532 and enhancing the rotational stability of the output shaft 532.

[0145] For example, asFigure 10 As shown, a part of the motor housing 53 is located radially outside the rotor part 52, increasing the connection area and achieving stable fixation of the rotor part 52.

[0146] In some embodiments, the motor housing 53 and the exhaust fan 7 are integrally injection-molded parts, thereby reducing the processing steps and improving the connection firmness between the motor housing 53 and the exhaust fan 7.

[0147] In some embodiments, the outer surface of the stator part 51 is an insulating and waterproof surface. In this way, even if the air entering the exhaust air duct V02 from the exhaust air inlet 901 carries a part of moisture, due to the protection of the insulating and waterproof surface for the stator part 51, this part of moisture will not erode the stator part 51, and further the second motor 5 has high working reliability. For example, when there is condensed water on the indoor heat exchanger 2, or when there is condensed water attached to the surface of the parts near the indoor heat exchanger 2 in the accommodation cavity V1, the condensed water is sucked into the exhaust air duct V02 by the exhaust fan 7. Even if the condensed water enters the second motor 5, it will not cause damage to the second motor 5.

[0148] For example, the stator part 51 includes a stator body 511 and a base body 512. The base body 512 is coated outside the stator body 511. Thus, the stator body 511 is not exposed. The base body 512 can be made of plastic material and has good insulating and waterproof functions. Due to the coating of the base body 512 on the stator body 511, moisture will not erode the stator part 51, and further the second motor 5 has high working reliability.

[0149] In some embodiments, the stator body 511 and the base body 512 are injection-molded as one body.

[0150] In some embodiments, the base body 512 is attached to the outside of the stator body 511.

[0151] In some embodiments, referring to Figure 19 As shown, the wall-mounted air conditioner 10000 further includes an end plate 31. The end plate 31 is located at one end of the indoor heat exchanger 2 close to the exhaust fan 7, and the end plate 31 is connected to the indoor heat exchanger 2. The end plate 31 is used to mount the indoor heat exchanger 2 on the base 3.

[0152] A gap V31 is provided between the end plate 31 and the exhaust air volute 9. The gap V31 is used to form a channel for indoor air to flow from the heat exchange air inlet 101 to the exhaust air inlet 901. Specifically, when the exhaust fan 7 rotates, indoor air can be sucked into the housing 1 through the heat exchange air inlet 101. At least a part of the indoor air in the housing 1 can enter the exhaust air inlet 901 through the gap V31, and thus enter the exhaust air duct V02.

[0153] The end plate 31 includes an end plate body 311 and an end plate convex portion 312. The end plate convex portion 312 protrudes towards the exhaust air volute 9 relative to the end plate body 311. In the length direction of the heat exchange fan 41, the distance between the end plate body 311 and the exhaust air volute 9 is T, where T≥10mm and T≤30mm.

[0154] In some embodiments, the end plate convex portion 312 and the end plate body 311 may be an integral part or a fixed connection structure.

[0155] The distance T between the end plate body 311 and the exhaust air volute 9 refers to: in the length direction of the heat exchange fan 41, the distance between the point on the end plate body 311 closest to the exhaust air volute 9 and the point on the exhaust air volute 9 closest to the end plate body 311.

[0156] In some embodiments, in the length direction of the heat exchange fan 41, the distance T between the end plate body 311 and the exhaust air volute 9 is not less than 10mm, that is, T≥10mm. When the distance T between the end plate body 311 and the exhaust air volute 9 is less than 10mm, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is too close, the gap V31 is too small, and the air volume between the exhaust air volute 9 and the end plate body 311 is small, resulting in a small air volume entering the exhaust air inlet 901, making it difficult to meet the exhaust demand. By setting the distance T between the end plate body 311 and the exhaust air volute 9 to be not less than 10mm, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is not too close, the air volume in the gap V31 is sufficient, and the air volume entering the exhaust air inlet 901 is large, thus meeting the exhaust demand.

[0157] In some embodiments, in the length direction of the heat exchange fan 41, the distance T between the end plate body 311 and the exhaust air volute 9 is not greater than 30mm, that is, T≤30mm. When the distance T between the end plate body 311 and the exhaust air volute 9 is greater than 30mm, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is too far, the gap V31 is too large, resulting in an increase in the overall length of the wall-mounted air conditioner 10000, occupying a large space, which is not conducive to the miniaturized design of the structure. By setting the distance T between the end plate body 311 and the exhaust air volute 9 to be not greater than 30mm, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is not too far, the overall length of the wall-mounted air conditioner 10000 is not too long, the wall-mounted air conditioner 10000 occupies a small space, which is conducive to the miniaturized design of the structure. At the same time, the air volume in the gap V31 is sufficient, and the air volume entering the exhaust air inlet 901 is large, thus meeting the exhaust demand.

[0158] For example, the distance T between the end plate body 311 and the exhaust air volute 9 can be 11 mm, 13 mm, 15 mm, 18 mm, 20 mm, etc.

[0159] In some embodiments, in the length direction of the heat exchange fan 41, the distance T between the end plate body 311 and the exhaust air volute 9 is 13 mm. In this way, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is not too close, and the air volume in the gap V31 is sufficient, so that the air volume entering the exhaust air inlet 901 is large, thus meeting the exhaust air demand. At the same time, the distance between the exhaust air inlet 901 of the exhaust air volute 9 and the end plate body 311 is not too far, the overall length of the wall-mounted air conditioner 10000 is not too long, the space occupied by the wall-mounted air conditioner 10000 is small, which is beneficial to the miniaturized design of the structure.

[0160] In some embodiments, in the height direction of the main body 1000, the fresh air inlet 801 is located below 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. Here, this pipeline is called the fresh air introduction pipe. The fresh air introduction pipe can be a part of the wall-mounted air conditioner 10000, or a fresh air introduction pipe separately configured by the user after purchasing the wall-mounted air conditioner 10000.

[0161] By arranging the fresh air inlet 801 below the main body 1000, the fresh air introduction pipe can be connected to the fresh air inlet 801 from below, and the connection part extends substantially in the up-down direction, rather than extending in the front-back direction to make the main body 1000 too thick. Thus, the wall-mounted air conditioner 10000 can still maintain a thin and light appearance. Moreover, the part of the fresh air volute 8 where the fresh air fan 6 is installed is circular. Based on the axis of the fresh air volute 8 extending in the length direction of the heat exchange fan 41, there is free space on both the front side and the rear side of the bottom of the circle. This part of the space can be used to arrange the fresh air inlet 801 to connect the fresh air introduction pipe. Thus, the connection part between the fresh air introduction pipe and the fresh air inlet 801 can be placed in this free space without occupying additional space, so that the height dimension of the main body 1000 can be controlled.

[0162] In some embodiments, in the height direction of the main body 1000, the exhaust air outlet 902 is located below the main body 1000. It can be understood that the exhaust air outlet 902 needs to be connected to a pipeline to guide the indoor air to the outside. Here, this pipeline is called the exhaust air lead-out pipe. The exhaust air lead-out pipe can be a part of the wall-mounted air conditioner 10000, or an exhaust air lead-out pipe separately configured by the user after purchasing the wall-mounted air conditioner 10000.

[0163] The exhaust air outlet 902 is arranged below the main body 1000, so that the exhaust air lead-out pipe can be connected to the exhaust air outlet 902 from below, and the connection part extends generally in the vertical 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 thin and light shape. Moreover, the part of the exhaust air volute 9 where the exhaust air fan 7 is installed is circular. Based on the axis of the exhaust air volute 9 extending along the length direction of the heat exchange fan 41, there is free space on both the front side and the rear side at the bottom of the circle. And based on the characteristics of the axial air intake and radial air outlet of the exhaust air fan 7, the diffuser section of the exhaust air volute 9 can be arranged generally in the vertical direction and can be placed in the above-mentioned front or rear free space.

[0164] An exhaust air outlet 902 is arranged here to connect the exhaust air lead-out pipe, so that the connection part between the exhaust air lead-out pipe and the exhaust air outlet 902 can be placed in this free space without occupying additional space, so that the height dimension of the main body 1000 can be controlled.

[0165] In some embodiments, the wall-mounted air conditioner 10000 may include: a fresh air inlet pipe connecting the fresh air inlet 801 and an exhaust air lead-out pipe connecting the exhaust air outlet 902. A pipe avoidance opening is provided on the bottom wall of the casing 1, and the fresh air inlet pipe and the exhaust air lead-out pipe are passed through the pipe avoidance opening and extend out of the main body 1000 from below. The fresh air inlet pipe and the exhaust air lead-out pipe are two independent pipe components, which helps to separate the fresh air flow path and the exhaust air flow path from each other, without crossing, and reduces the risk of air leakage caused by mutual cross-flow.

[0166] A pipe avoidance opening is arranged on the bottom wall of the main body 1000, which is convenient for installing the above pipelines and ensures the beautiful appearance of the main body 1000. The fresh air inlet pipe and the exhaust air lead-out pipe are connected from below the main body 1000, which does not affect the upper area after the wall-mounted air conditioner 10000 is hung on the indoor wall, that is, the fresh air inlet pipe and the exhaust air lead-out pipe will neither interfere with the rear wall nor with the upper roof, and the wall-mounted air conditioner 10000 is more convenient and fast to install.

[0167] In some embodiments, the air inlet direction of the fresh air inlet 801 is set upward. For example, the air inlet direction of the fresh air inlet 801 is perpendicular to the length direction of the heat exchange fan 41. In this way, after the two-way ventilation component is arranged at the end of the wall-mounted air conditioner 10000, when the fresh air inlet pipe is connected to the fresh air inlet 801, the fresh air inlet pipe will not make the whole wall-mounted air conditioner 10000 overly elongated.

[0168] In some embodiments, the fresh air inlet 801 is located at the bottom of the main body 1000 and is arranged close to the rear side. In this way, after the fresh air inlet pipe is connected to the fresh air inlet 801, it is convenient for the fresh air inlet pipe to be arranged against the wall.

[0169] In some embodiments, the air outlet direction of the exhaust air outlet 902 is set downward. For example, the air outlet direction of the exhaust air outlet 902 is perpendicular to the length direction of the heat exchange fan 41. In this way, after the two-way ventilation component is arranged at the end of the wall-mounted air conditioner 10000, when the exhaust air outlet pipe is connected to the exhaust air outlet 902, the exhaust air outlet pipe will not cause the overall length of the wall-mounted air conditioner 10000 to be overly elongated.

[0170] In some embodiments, the exhaust air outlet 902 is located at the bottom of the main body 1000 and is arranged close to the rear side. In this way, after the exhaust air outlet pipe is connected to the exhaust air outlet 902, it is convenient for the exhaust air outlet pipe to be arranged along the wall.

[0171] Of course, some embodiments are not limited to this. For example, Figure 1 As shown, the pipe avoidance port 104 can also be arranged on the side wall of the casing 1. After the fresh air inlet pipe is connected to the fresh air inlet 801 from below the main body 1000, it bends and extends horizontally, then extends out from the pipe avoidance port 104 on the side wall of the casing 1, and then extends to the outside. After the exhaust air outlet pipe is connected to the exhaust air outlet 902 from below the main body 1000, it bends and extends horizontally, then extends out from the pipe avoidance port 104 on the side wall of the casing 1, and then extends to the outside.

[0172] It can be understood that the refrigerant pipe and the drain pipe are usually arranged at one end of the main body 1000 in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 with the compressor and the outdoor heat exchanger outside, and the drain pipe is used to discharge the condensed water generated in the wall-mounted air conditioner 10000.

[0173] The pipe avoidance port 104 is arranged on the side wall of the casing 1, and then the fresh air inlet pipe and the exhaust air outlet pipe are arranged horizontally and then led out, which is convenient for at least one of the fresh air inlet pipe and the exhaust air outlet pipe to be arranged side by side with the drain pipe and the refrigerant pipe. Then, the multiple pipes arranged side by side are covered by an outer bundle pipe or a strap, so that the multiple pipes are formed into one pipe in appearance, so that the number of connecting pipes on the wall-mounted air conditioner 10000 after installation is small and the appearance is simple. This not only facilitates assembly but also avoids the risk of multiple pipes bumping into each other.

[0174] In some embodiments, for example, Figure 8 and Figure 11 As shown, the exhaust fan 7 forms an accommodation groove V07 at the radial center, and at least a part of the stator part 51, at least a part of the rotor part 52, and at least a part of the motor casing 53 of the second motor 5 are accommodated in the accommodation groove V07.

[0175] For example, the hub of the exhaust fan 7 forms the accommodation groove V07. At this time, the main body part (i.e., the stator part 51 and the rotor part 52) of the second motor 5 and the motor casing 53 can be placed at the center of the exhaust fan 7, which will not hinder the flow of the exhaust air, and can make full use of the hub space of the exhaust fan 7 to reduce the occupied space of the second motor 5 outside.

[0176] Moreover, after the hub of the exhaust fan 7 is sleeved outside the second motor 5, it has a protective effect and can also make the center of mass of the exhaust fan 7 as close as possible to the center of the rotor part 52. As a result, the bending moment generated by the exhaust fan 7 on the second motor 5 is small, the exhaust fan 7 has little shaking during rotation, the exhaust fan 7 operates stably and has low energy consumption.

[0177] In some embodiments, as Figure 1 shown, a housing air outlet 105 is provided on the housing 1. The housing air outlet 105 is arranged corresponding to the fresh air outlet 802 of the fresh air volute 8, so that the fresh air discharged from the fresh air outlet 802 is discharged from the housing air outlet 105.

[0178] In some embodiments, the fresh air outlet 802 is located directly in front of the main body 1000, and the housing air outlet 105 can correspondingly be arranged on the front side of the housing 1, so as to facilitate outputting fresh air directly in front of the main body 1000. When the wall-mounted air conditioner 10000 is installed on a wall, especially at a high position on the wall, there are fewer obstacles directly in front, and blowing air from directly in front can ensure a relatively large air supply area for fresh air.

[0179] In some embodiments, the fresh air outlet 802 is located at the top of the main body 1000, and the housing air outlet 105 can correspondingly be arranged on the top wall of the housing 1. In this way, the fresh air blown out from the fresh air outlet 802 towards the roof can utilize the roof to guide the flow direction of the fresh air, so that the fresh air flows along the roof and the air supply area is expanded.

[0180] Moreover, since the heat exchange air inlet 101 is located above the heat exchange air outlet 102 and the position of the heat exchange air inlet 101 on the housing 1 is relatively high, part of the fresh air blown out from the fresh air outlet 802 at the top can be re-inhaled into the accommodation cavity V1 through the heat exchange air inlet 101 and flow through the indoor heat exchanger 2.

[0181] Such an arrangement is beneficial in that on the one hand, it helps the fresh air to quickly reach the room temperature and improves the comfort when the fresh air is blown in, and on the other hand, it is beneficial for the fresh air to be fully mixed with the indoor air flowing through the indoor heat exchanger 2, so that the air blown into the room from the heat exchange air outlet 102 is overall fresh, improving the uniformity of the fresh air distribution in the room.

[0182] In some embodiments, the fresh air outlet 802 is located below the main body 1000 to guide the fresh air to flow forward and downward into the room. The housing air outlet 105 can correspondingly be arranged on the lower part of the housing 1.

[0183] Since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the position of the heat exchange air outlet 102 on the housing 1 is relatively lower, the fresh air outlet 802 blows out fresh air from below, making the air outlet area of the housing air outlet 105 close to or even partially overlapping with the air outlet area of the heat exchange air outlet 102. This is beneficial for the fresh air to mix with the indoor air after heat exchange. On the one hand, it improves the uniformity of the fresh air mixed in the indoor air. On the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, making the temperature of the fresh air tend to the indoor temperature and improving the blowing comfort.

[0184] Moreover, the air outlet direction of the fresh air outlet 802 is opposite to the air inlet direction of the heat exchange air inlet 101, so that the fresh air will not be sucked into the heat exchange air inlet 101, reducing the proportion of the fresh air inlet volume at the heat exchange air inlet 101, making the total air outlet volume of the wall-mounted air conditioner 10000 larger and improving the overall circulation efficiency of the indoor air.

[0185] Moreover, the fresh air outlet 802 is located below the main body 1000 and is close to the people's activity space, which is convenient for people to observe the fresh air outlet condition. This achieves the visual effect of fresh air outlet and is beneficial to improving people's experience perception.

[0186] For example, when the fresh air outlet 802 is located below the main body 1000, it is usually located at the front side below the main body 1000, so that the fresh air can flow forward and downward, ensuring both that the fresh air can reach the ground and that the fresh air can reach a sufficient distance.

[0187] For example, as Figure 1 and Figure 3 shown, a grille 16 is provided at the housing air outlet 105 of the housing 1 to adjust the air outlet direction of the fresh air.

[0188] In some embodiments, as Figure 3 shown, the exhaust air inlet 901 is formed on the exhaust air volute 9, and the axial direction of the exhaust air inlet 901 is set along the length direction of the heat exchange fan 41. That is to say, the exhaust air inlet 901 is directly opposite to the axial air inlet end of the exhaust fan 7, making the air inlet resistance of the exhaust fan 7 from the exhaust air inlet 901 small and beneficial to ensuring the exhaust air inlet volume. When the exhaust air inlet is relatively easy, a smaller-sized exhaust fan 7 can be selected to further reduce the size of the two-way ventilation component.

[0189] For example, the axial direction of the exhaust air inlet 901 faces the indoor heat exchanger 2, that is, the air inlet area of the exhaust air inlet 901 faces the indoor heat exchanger 2. In this way, the exhaust air inlet 901 is relatively close to the heat exchange air inlet 101, and the air inlet volume at the heat exchange air inlet 101 is relatively large. A part of the air entering the housing 1 from the heat exchange air inlet 101 can enter the exhaust air volute 9 through the exhaust air inlet 901, making the air volume at the exhaust air inlet 901 sufficient.

[0190] In some embodiments, as Figure 1 shown, a first continuous ventilation duct V04 is formed between the heat exchange air inlet 101 and the exhaust air inlet 901. The rotation of the exhaust fan 7 drives the indoor air to enter the first continuous ventilation duct V04 from the heat exchange air inlet 101, and makes the indoor air enter the exhaust volute 9 through the exhaust air inlet 901.

[0191] That is to say, there is no need to connect a physical pipe between the heat exchange air inlet 101 and the exhaust air inlet 901, and the air flow is only sucked in from the top by the wind pressure.

[0192] In some embodiments, the exhaust fan 7 can be made of plastic, so that it is light in weight and low in cost. Of course, in some embodiments, this is not limited, and the exhaust fan 7 can also be made of resin, metal, etc.

[0193] In some embodiments, the exhaust fan 7 can be made of plastic, so that it is light in weight and low in cost. In some embodiments, the exhaust fan 7 can also be made of resin, metal, etc.

[0194] In some embodiments, the fresh air fan 6 can be made of plastic, so that it is light in weight and low in cost. In some embodiments, the fresh air fan 6 can also be made of resin, metal, etc.

[0195] Similarly, the exhaust volute 9 can be made of plastic, so that it is light in weight and low in cost. For example, the exhaust volute 9 can be an injection molded part. In some embodiments, the exhaust volute 9 can also be made of metal, etc.

[0196] The fresh air volute 8 can be made of plastic, so that it is light in weight and low in cost. For example, the fresh air volute 8 can be an injection molded part. In some embodiments, the fresh air volute 8 can also be made of metal, etc.

[0197] In some embodiments, the area of the outer circular surface of the fresh air fan 6 is S1, and the area of the outer circular surface of the exhaust fan 7 is S2. It satisfies that S1 > S2.

[0198] For example, S1 = πD1×h1, where D1 is the outer diameter of the fresh air fan 6, and h1 is the total thickness of the fresh air wheel disc 61 and the fresh air blades 62 of the fresh air fan 6 in the axial direction.

[0199] The fresh air fan 6 includes: a fresh air wheel disc 61 and fresh air blades 62. The fresh air blades 62 are located at the outer edge of the fresh air wheel disc 61, and the fresh air blades 62 extend along the axial direction of the fresh air wheel disc 61. The total thickness of the fresh air wheel disc 61 and the fresh air blades 62 in the axial direction is h1. Here, the fresh air wheel disc 61 on the fresh air fan 6 can be one, or at least two axially spaced apart. On each axial side of each fresh air wheel disc 61, only one circle of fresh air blades 62 can be arranged on one side, or one circle of fresh air blades 62 can be arranged on each side. h1 is the maximum dimension of the fresh air fan 6 in the axial direction of the fresh air fan 6.

[0200] S2 = πD2×h2, where D2 is the outer diameter of the exhaust fan 7, and h2 is the total axial thickness of the exhaust wheel disc 71 and the exhaust blades 72 on the exhaust fan 7.

[0201] The exhaust fan 7 includes an exhaust wheel disc 71 and exhaust blades 72. The exhaust blades 72 are located at the outer edge of the exhaust wheel disc 71 and extend along the axial direction of the exhaust wheel disc 71. The total axial thickness of the exhaust wheel disc 71 and the exhaust blades 72 is h2. Here, the exhaust wheel disc 71 on the exhaust fan 7 can be one, or at least two spaced apart along the axial direction. On either side of the axial direction of each exhaust wheel disc 71, only one circle of exhaust blades 72 can be provided on one side, or one circle of exhaust blades 72 can be provided on each side. When all the exhaust wheel discs 71 and the exhaust blades 72 are projected perpendicularly onto the axis of the exhaust fan 7, the distance between the two farthest points in the projection is equal to h2.

[0202] With such a setting, the outer circular surface area of the fresh air fan 6 is large, and the outer circular surface area of the exhaust fan 7 is small, which is beneficial to achieving a large fresh air volume under the condition of limited overall machine space size.

[0203] For example, according to the structural and functional requirements designed in some embodiments, the outer diameter D1 of the fresh air fan 6 is greater than the outer diameter D2 of the exhaust fan 7, which is beneficial to making the area swept by the fan blades of the fresh air fan 6 when rotating larger than the area swept by the fan blades of the exhaust fan 7 when rotating. In this way, the fresh air volume is greater than the exhaust air volume, meeting the design requirements of the wall-mounted air conditioner 10000. That is, air is inhaled from the infinite outdoor space and sent into the room, which consumes less energy compared to sucking air from the relatively enclosed indoor space and discharging it outdoors. Moreover, the air freshness in the outdoor environment is high, and inhaling air from the outdoor and blowing it into the room is more conducive to supplementing fresh air in the indoor space, replenishing the oxygen content and reducing the carbon dioxide content in the indoor air.

[0204] The exhaust air outlet 902 of the exhaust air duct V02 and the fresh air outlet 802 of the fresh air duct V01 are staggeredly arranged on the outer periphery of the two-way ventilation component. On the one hand, this facilitates connecting an exhaust air leading pipe to the exhaust air outlet 902 and a fresh air inlet pipe to the fresh air inlet 801. On the other hand, it is easy to ensure that the flow paths of fresh air and exhaust air in the two-way ventilation component do not cross. The exhaust air outlet 902 and the fresh air outlet 802 are staggeredly arranged, resulting in the outer diameter D2 of the exhaust fan 7 being smaller than the outer diameter D1 of the fresh air fan 6.

[0205] For example, as Figure 7 shown, the fresh air volute 8 has a fresh air diffuser section 805, and the fresh air outlet 802 is located at the end of the fresh air diffuser section 805. That is to say, the part of the fresh air volute 8 from its volute tongue to the fresh air outlet 802 is the fresh air diffuser section 805.

[0206] For example, the volute tongue of the fresh air volute 8 and the volute tongue of the exhaust air volute 9 are staggered in the circumferential direction of the second motor 5 .

[0207] In this way, it is easy to stagger the exhaust outlet 902 of the exhaust duct V02 and the fresh air outlet 802 of the fresh air duct V01 on the outer periphery of the two-way ventilation component, which is convenient for connecting the exhaust outlet 902 to the exhaust air outlet and the fresh air inlet 801 to the fresh air inlet pipe, avoiding interference caused by the close distance between the two pipe joints, which is not only convenient for assembly but also convenient for sealing.

[0208] Furthermore, in some embodiments, the exhaust outlet 902 is positioned downward, while the fresh air outlet 802 is positioned forward. This not only allows the pipe connections of the exhaust outlet 902 and the fresh air outlet 802 to be directly staggered, but also facilitates the connection of the exhaust outlet 902 with the fresh air inlet pipe, allowing them to be positioned against a wall. The forward-facing fresh air outlet 802 allows the fresh air to be delivered forward, expanding the fresh air supply range.

[0209] For example, the exhaust outlet 902 is located at the rear side of the exhaust volute 9, and the air outlet direction of the exhaust outlet 902 is set downward. In this way, when the exhaust outlet 902 is connected to the exhaust outlet duct, the exhaust outlet duct will not excessively stretch the entire wall-mounted air conditioner 10000. In addition, the exhaust outlet 902 is left on the side of the exhaust volute 9 that is close to the wall, making it easier to make the main body 1000 have a shape that is wider at the back and narrower at the front.

[0210] When the main body 1000 is designed to be wide at the back and narrow at the front, with the wider back portion mounted against the wall, people viewing the wall-mounted air conditioner 10000 will see the narrower front portion, creating the impression that the wall-mounted air conditioner 10000 is thinner and lighter. This can reduce the perceived heaviness of the wall-mounted air conditioner 10000, thereby alleviating the feeling of oppression that may arise from hanging the wall-mounted air conditioner 10000 on the wall.

[0211] In some embodiments, the fresh air outlet 802 is arranged to be downward and tilted forward, which is conducive to allowing the wall-mounted air conditioner 10000 to discharge fresh air forward, ensuring that the fresh air can be delivered to the ground and to a sufficiently long distance.

[0212] For example, the fresh air outlet 802 is located in front of the exhaust air outlet 902, so that the fresh air outlet 802 and the exhaust air outlet 902 are staggered at a greater distance, which is more conducive to reducing mutual interference and facilitating takeover.

[0213] In some embodiments, the outer diameter D1 of the fresh air fan 6 is larger than the outer diameter D2 of the exhaust fan 7 to ensure that the fresh air volume is larger than the exhaust air volume.

[0214] Suitable, such asFigure 14 As shown, the fresh air volute 8 includes a first volute shroud 812 surrounding the radially outer side of the fresh air fan 6, and the exhaust air volute 9 includes a second volute shroud 906 surrounding the radially outer side of the exhaust air fan 7. The diameter of the first volute shroud 812 is larger than that of the second volute shroud 906. This can make the component parts compact and reduce the overall occupied space.

[0215] Moreover, more space can be vacated on the radially outer side of the second volute shroud 906, enabling air to flow in the space on the radially outer side of the exhaust air volute 9 inside the casing 1. In this way, when the exhaust air volute 9 sucks in air from the exhaust air inlet 901, more air can enter, which is beneficial to increasing the exhaust air intake volume.

[0216] In some embodiments, in the height direction of the main body 1000, the fresh air inlet 801 is located below the main body 1000, and in the length direction of the heat exchange fan 41, the fresh air outlet 802 is located between the fresh air inlet 801 and the exhaust air outlet 902. With such an arrangement, the fresh air inlet 801, the fresh air outlet 802, the exhaust air outlet 902, and the connection pipe positions are compact, which is beneficial to reducing the overall size.

[0217] In some embodiments, as Figure 1 shown, an air outlet 105 is provided on the casing 1, and the air outlet 105 of the casing is arranged corresponding to the fresh air outlet 802. As Figure 3 shown, the wall-mounted air conditioner 10000 may include: an expansion pipe 19 connected between the air outlet 105 of the casing and the fresh air outlet 802, and the flow-through area of the expansion pipe 19 increases in the direction towards the air outlet 105 of the casing. That is to say, the expansion pipe 19 enables the fresh air to undergo a further pressure boosting process, thereby further increasing the fresh air pressure and further expanding the air supply range.

[0218] For example, the exhaust air outlet 902 and the fresh air inlet 801 are located below the main body 1000 and close to the rear side, so that there will be no excessive interference with the expansion pipe 19 after connection.

[0219] In some embodiments, in the length direction of the heat exchange fan 41, the size L3 of the air outlet 105 of the casing (as Figure 1 shown) is larger than the sum of the thicknesses of the fresh air fan 6 and the exhaust air fan 7. Here, as Figures 11 - 12 shown, the thickness of the fresh air fan 6 in the length direction of the heat exchange fan 41 is h1, and the thickness of the exhaust air fan 7 in the length direction of the heat exchange fan 41 is H20. The sum of h1 and H20 is less than the length L3 of the air outlet 105 of the casing. The purpose of this device is to make the air outlet 105 of the casing longer in the length direction of the heat exchange fan 41 and make full use of the spare space provided by the two-way ventilation component in this direction. This is beneficial to elongating the fresh air outlet in this direction, expanding the fresh air outlet width, and sending the fresh air to a wider area.

[0220] In some embodiments, as Figure 11 shown, on the exhaust fan 7, the total axial thickness of the exhaust wheel disc 71 and the exhaust blades 72 is h2, as Figure 12 shown, on the fresh air fan 6, the total axial thickness of the fresh air wheel disc 61 and the fresh air blades 62 is h1. For example, h2 < h1. With such a setting, while ensuring that the fresh air volume is greater than the exhaust air volume, the axial thickness of the main body part of the fresh air fan 7 is made larger, so that the structural strength is greater and it can bear a greater torque. The exhaust air volume requirement of the exhaust fan 7 is small, and the smaller axial thickness of the main body part can appropriately reduce the exhaust air volume and at the same time reduce the axial dimension of the two-way ventilation component.

[0221] In some embodiments, as Figure 10 shown, the total axial thickness of the stator part 51, the rotor part 52 and the motor housing 53 is h3. The exhaust fan 7 includes an exhaust wheel disc 71 and exhaust blades 72. The exhaust blades 72 are located at the outer edge of the exhaust wheel disc 71 and extend along the axial direction of the exhaust wheel disc 71. The total axial thickness of the exhaust wheel disc 71 and the exhaust blades 72 is h2. It satisfies h3 > h2. It can be understood that the second motor 5 needs to drive the fresh air fan 6 and the exhaust fan 7 at the same time. Although the exhaust air volume is designed to be small, the fresh air volume is designed to be large. Therefore, the total axial thickness of the stator part 51, the rotor part 52 and the motor housing 53 is set to be greater than the axial thickness of the main body part of the exhaust fan 7 to ensure that the second motor 5 can support the rotation of the two fans and improve the sufficient supporting force of the second motor 5.

[0222] For example, the exhaust fan 7 may include a protrusion 74. The protrusion 74 is provided on the exhaust wheel disc 71. The center of the protrusion 74 is located on the axis of the exhaust fan 7, and the protrusion 74 extends in the direction towards the fresh air fan 6 relative to the exhaust wheel disc 71, so that a receiving groove V07 for the second motor 5 is formed on the side of the protrusion 74 close to the second motor 5, and at least a part of the stator part 51 and at least a part of the rotor part 52 are received in the receiving groove V07.

[0223] Due to the limited overall length dimension of the machine, the axial dimension of the two-way ventilation component is limited. To ensure the power efficiency, the axial thickness of the second motor 5 is certain. To increase the fresh air volume, the fresh air blades 62 of the fresh air fan 6 extend towards the second motor 5, resulting in a depression in the central area of the fresh air blades 62. To avoid the fresh air blades 62 of the fresh air fan 6, the exhaust blades 72 of the exhaust fan 7 are arranged in a direction away from the fresh air blades 62 relative to the exhaust wheel disc 71, and a protrusion 74 is formed on the exhaust wheel disc 71. The protrusion 74 extends into the depression space in the central area where the fresh air blades 62 appear, thereby reducing the axial dimension of the two-way ventilation component.

[0224] In some embodiments, the total thickness of the stator portion 51, the rotor portion 52 and the motor housing 53 in the axial direction is h3, and the total thickness of the fresh air wheel disc 61 and the fresh air blades 62 on the fresh air fan 6 in the axial direction is h1, where h1 > h3. This also ensures a large fresh air volume, and the second motor 5 does not need to occupy too much duct space.

[0225] In some embodiments, as Figure 11 and Figure 14 shown, the exhaust fan 7 includes an exhaust wheel disc 71 and exhaust blades 72. The exhaust blades 72 are located at the outer edge of the exhaust wheel disc 71, and the exhaust blades 72 extend along the axial direction of the exhaust wheel disc 71 in a direction away from the fresh air fan 6.

[0226] Referring to Figure 5 and Figure 15 , the fresh air volute 8 includes: a first volute 81 and a second volute 82. The first volute 81 is located on the side of the exhaust volute 9 away from the heat exchange fan 41, and the first volute 81 is detachably connected to the exhaust volute 9. The second volute 82 is located on the side of the first volute 81 away from the heat exchange fan 41, and the second volute 82 is detachably connected to the first volute 81. The first volute 81 is located between the exhaust volute 9 and the second volute 82.

[0227] Referring to Figure 14 , the first volute 81 includes a first volute end plate 811 and a first volute shroud 812. The first volute shroud 812 is formed by extending along the edge of the first volute end plate 811 in a direction away from the exhaust fan 7.

[0228] For example, a recessed portion 813 is formed in the central portion area of the first volute end plate 811. The recessed portion 813 is recessed towards the fresh air fan 6, and a perforated portion 814 is provided at the center of the recessed portion 813. At least a part of the protruding portion 74 is located in the recessed portion 813, and the output shaft 532 is connected to the fresh air fan 6 through the perforated portion 814.

[0229] In some embodiments, dividing the fresh air volute 8 into at least the first volute 81 and the second volute 82 for separate processing along the axial direction can reduce the manufacturing and assembly difficulties. Moreover, for such a complex housing, separate manufacturing facilitates quality control. Detachably connecting the first volute 81 to the exhaust volute 9 and detachably connecting the second volute 82 to the first volute 81 facilitates assembly and also subsequent adjustment and maintenance.

[0230] A raised portion 74 is provided at the center of the exhaust air wheel disc 71, and a recessed portion 813 is formed at the center of the first volute end plate 811. On the one hand, the hub of the exhaust air fan 7 is used to form the raised portion 74 to accommodate the second motor 5, and the raised portion 74 can improve the structural strength of the exhaust air fan 7. On the other hand, the main body portion of the second motor 5 is assembled within the raised portion 74, occupying more of the exhaust air duct V02 and less of the fresh air duct V01, which matches the design where the fresh air volume is greater than the exhaust air volume. Only the output shaft 532 passes through the first volute end plate 811, which helps with sealing, reduces the chance of mutual leakage between fresh air and exhaust air, and reduces air flow disturbance.

[0231] In some embodiments, to make the wall-mounted air conditioner 10000 more reliable, the external dimensions of the main body 1000 are strictly controlled. In this way, not only are the internal part clearances small and not easily loosened, but also each air duct can be designed to be shorter, the size of the housing 1 is reduced, thereby reducing the overall weight of the main body 1000 and making it visually thinner and lighter.

[0232] When controlling the size of the main body 1000, the key is how to reduce the structural size of the two-way ventilation component. Among the two-way ventilation components, it is necessary to first ensure that the second motor 5 can output sufficient power to meet the requirements of the exhaust air volume and fresh air volume. Therefore, the thickness dimension of the second motor ⑤, especially the total axial thickness h3 of the stator portion 51, the rotor portion 52 and the motor housing 53 needs to be large enough, and the total axial thickness h3 of the stator portion 51, the rotor portion 52 and the motor housing 53 is greater than the axial thickness h2 of the main body portion of the exhaust air fan 7.

[0233] After the second motor 5 occupies a certain thickness dimension, in order to prevent the structural size of the two-way ventilation component from expanding excessively, when optimizing the exhaust air fan 7, a raised portion 74 is provided at the center of the exhaust air wheel disc 71. The raised portion 74 extends in the direction of the fresh air fan 6 relative to the exhaust air wheel disc 71, so that a receiving groove V07 for the second motor 5 is formed on the side of the raised portion 74 close to the second motor 5. At least a part of the stator portion 51 and at least a part of the rotor portion 52 are accommodated in the receiving groove V07, and a central partial area of the first volute end plate 811 of the first volute 81 is formed into a recessed portion 813 facing the inside of the fresh air fan 6, so that at least a part of the raised portion 74 is located in the recessed portion 813.

[0234] With such a setting, it is also beneficial to reduce the distance between the main body portion of the second motor 5 and the fresh air fan 6, thereby facilitating the reduction of the axial distance between the fresh air fan 6 and the main body portion of the second motor 5, reducing the bending moment generated by the fresh air fan 6 on the output shaft 532. When the second motor 5 is in motion, the coaxiality of the fresh air fan 6 and the exhaust air fan 7 is relatively high, not easily shaken, and can avoid abrasion and vibration caused by friction with the volute.

[0235] In some embodiments, referring to Figure 8, the fresh air fan 6 includes a fresh air recess 63 provided on the fresh air wheel disc 61. The fresh air recess 63 extends in a direction away from the exhaust fan 7 relative to the fresh air wheel disc 61, and at least a part of the recess 813 is located within the fresh air recess 63. With this arrangement, it is beneficial to further reduce the distance between the main body part of the second motor 5 and the fresh air fan 6, thereby facilitating the reduction of the axial distance between the fresh air fan 6 and the main body part of the second motor 5, reducing the bending moment generated by the fresh air fan 6 on the output shaft 532. When the second motor 5 operates, the fresh air fan 6 and the exhaust fan 7 have a high coaxiality, are not prone to shaking, and can avoid wear and vibration caused by friction with the volute casing.

[0236] In some embodiments, referring to Figure 8 , the exhaust volute 9 and the fresh air volute 8 are connected, sharing the first volute end plate 811 therebetween, and the fresh air duct V01 and the exhaust duct V02 are separated by the first volute end plate 811. This arrangement eliminates the need for an intervening gap between the exhaust volute 9 and the fresh air volute 8, further reducing the axial dimension of the two-way ventilation assembly and the occupied space within the wall-mounted air conditioner 10000, which is beneficial for the overall thin and light design of the wall-mounted air conditioner 10000.

[0237] For example, the first volute end plate 811 is a single-layer plate, which simplifies the structure and is beneficial for reducing the overall axial dimension.

[0238] In some embodiments, referring to Figure 8 、 Figure 11 and Figure 14 , the exhaust fan 7 includes: an exhaust wheel disc 71 and exhaust blades 72. The exhaust wheel disc 71 is coaxially arranged with the second motor 5 and is connected to the motor housing 53 of the second motor 5. There are multiple exhaust blades 72, which are provided on the exhaust wheel disc 71 and extend only in a direction away from the fresh air fan 6. The multiple exhaust blades 72 are arranged circumferentially on the exhaust wheel disc 71. For example, the exhaust fan 7 includes single-layer centrifugal blades. In this way, while meeting the requirement of small air volume, the exhaust fan 7 has a simple structure and low cost. Moreover, the blade cylinder formed by the circumferential arrangement of the exhaust blades 72 on the exhaust wheel disc 71 is open on the side facing the axial air inlet end, facilitating the inhalation of air, reducing the air suction resistance, and ensuring the air intake volume of the exhaust.

[0239] In some embodiments, referring to Figure 8 、 Figure 12 and Figure 14, the fresh air fan 6 includes: a fresh air impeller 61 and fresh air blades 62. The fresh air impeller 61 is coaxially arranged with the second motor 5, and the fresh air impeller 61 is connected to the output shaft 532 of the second motor 5. The fresh air blades 62 include first fresh air blades 621, and the first fresh air blades 621 extend from the fresh air impeller 61 in a direction away from the exhaust fan 7. The blade cylinder formed after the first fresh air blades 621 are arranged circumferentially is open on the side facing the axial air inlet end, which is convenient for air flow to be inhaled, reduces the air suction resistance, and ensures the fresh air intake volume.

[0240] For example, referring to Figure 8 , Figure 12 and Figure 14 , the fresh air blades 62 may include second fresh air blades 622, and the second fresh air blades 622 extend from the fresh air impeller 61 in a direction close to the exhaust fan 7. In this way, the fresh air fan 6 includes double-layer centrifugal blades. Thus, in the case of meeting the large air volume requirement, the double-layer centrifugal blade structure design helps to increase the overall structural strength of the centrifugal fan.

[0241] In some embodiments, 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 faces the axial air inlet end, so the axial length of the first fresh air blade 621 is larger, which is beneficial to obtaining a larger fresh air intake volume by using the first fresh air blade 621. And by using the shorter second fresh air blade 622, it is beneficial to make up for the fresh air intake. Moreover, the first fresh air blade 621 on the windward side is longer, which is beneficial to reducing noise while ensuring the fresh air volume.

[0242] In some embodiments, a wheel disc hole 612 is formed on the fresh air impeller 61, and one side of the second fresh air blade 622 can inhale air through the wheel disc hole 612, and the distance from the wheel disc hole 612 to the center of the fresh air impeller 61 is less than the distance from the fresh air blade 62 to the center of the fresh air impeller 61.

[0243] For example, the wheel disc hole 612 is closer to the center of the fresh air impeller 61 than the fresh air blade 62. In this way, it is beneficial for the second fresh air blade 622 to guide the air flow to be inhaled axially into the space where the second fresh air blade 622 is located when inhaling air from the wheel disc hole 612, and reduces the turbulent flow generated by competing for air with the first fresh air blade 621.

[0244] In some embodiments, referring to Figure 5 , Figure 8 and Figure 15, the second volute 82 includes: a second volute half 821 and a blower housing 822. The second volute half 821 is located on the side of the first volute 81 away from the exhaust fan 7, and the second volute half 821 is detachably connected to the first volute 81. An axial ventilation opening 8211 is provided at the radial center of the second volute half 821. A volute cavity V011 is formed between the second volute half 821 and the first volute 81. The fresh air fan 6 is located in the volute cavity V011, and the axial air inlet end of the fresh air fan 6 is arranged towards the axial ventilation opening 8211. The second volute half 821 and the first volute 81 jointly define a fresh air outlet 802.

[0245] In some embodiments, the volute cavity V011 and the indoor heat exchanger 2 are separated by the exhaust volute 9. In this way, the distance between the indoor heat exchanger 2 and the volute cavity V011 is far, and the ability of the indoor heat exchanger 2 to reduce the air temperature in the volute cavity V011 decreases, and the air in the volute cavity V011 is not likely to be supercooled to generate condensate.

[0246] The blower housing 822 is located on the side of the second volute half 821 away from the exhaust fan 7, and the blower housing 822 is detachably connected to the second volute half 821. Refer to Figure 8 , the cavity enclosed by the blower housing 822 and the second volute half 821 is the fresh air cavity V012, and the blower housing 822 and the second volute half 821 enclose a fresh air inlet 801.

[0247] After being arranged like this, a fresh air cavity V012 is formed at the air inlet end of the fresh air fan 6. The formed fresh air cavity V012 can cover the axial air inlet end of the fresh air fan 6, and the fresh air cavity V012 can be used to accommodate air, so that the air can enter the fresh air fan 6 vertically along the axis from the fresh air cavity V012, thereby improving the air suction efficiency of the fresh air fan 6 and reducing the air suction loss.

[0248] For example, the blower housing 822 is located on the side of the second volute half 821 away from the indoor heat exchanger 2, so that the fresh air cavity V012 can be separated from the indoor heat exchanger 2. The distance between the indoor heat exchanger 2 and the fresh air cavity V012 is far, and the ability of the indoor heat exchanger 2 to reduce the air temperature in the fresh air cavity V012 decreases, and the air in the fresh air cavity V012 is not likely to be supercooled to generate condensate.

[0249] In some embodiments, refer to Figure 3 , the wall-mounted air conditioner 10000 may include: a purification member 11, refer to Figure 8 , the purification member 11 is arranged in the fresh air duct V01 and is used to purify the fresh air blown into the room to improve the cleanliness of the indoor air.

[0250] For example, the purification component 11 is installed in the fresh air cavity V012. For example, the purification component 11 is located at the axial air inlet end of the fresh air fan 6. When the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can be blown through the purification component 11 and then enter the room from the fresh air outlet 802.

[0251] In this way, the fresh air flow can almost vertically pass through the purification component 11, and the fresh air intake consumption can be further reduced, thereby increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in the cooling state and condensing water is generated in the fresh air, the condensing water can remain on the purification component 11 when the air flows through the purification component 11, further avoiding the situation of water blowing when the fresh air device blows out air.

[0252] In some embodiments, the purification component 11 is connected to the second volute 82, which facilitates the assembly of the purification component 11 and prevents interference with the fresh air fan 6.

[0253] For example, as Figure 15 shown, the purification component 11 includes a filter net 111, and the filter net 111 covers the axial ventilation opening 8211. The filter net 111 covers the entire air inlet end of the fresh air fan 6. The filter net 111 has a large coverage area, a large filtering area, and good filtering effect. The setting of the filter net 111 helps to ensure sufficient contact area with the flowing air, and it is light in weight and has low air passing noise. For example, the filter net 111 is a HEPA net, so it has a strong adsorption force and a strong filtering effect on dust in the air.

[0254] For example, the filter net 111 is plate-shaped, so that the overall filter net 111 is relatively thin and will not occupy too much thickness when placed in the two-way ventilation component.

[0255] For example, the filter net 111 is square, which facilitates the positioning and installation of the filter net 111.

[0256] In some embodiments, the filter net 111 is a square net, and the side length of the filter net 111 is greater than the diameter of the axial ventilation opening 8211. The square net is convenient for positioning during fixation, is not easy to shake after fixation, and is easy to process with less processing waste. Making the side length of the filter net 111 greater than the diameter of the axial ventilation opening 8211 enables all the fresh air flowing through the axial ventilation opening 8211 to flow through the filter net 111, resulting in high filtering cleanliness.

[0257] In some embodiments, referring to Figure 8 , a part of the fresh air cavity V012 forms an empty cavity V0121. The cavity V0121 is located on the side of the purification component 11 away from the fresh air fan 6, and the fresh air inlet 801 is communicated with the cavity V0121.

[0258] For example, a purification member 11 is provided at a position in the fresh air chamber V012 close to the fresh air fan 6. The part of the fresh air chamber V012 away from the fresh air fan 6 is a cavity V0121, that is, the cavity V0121 exists between the oncoming wind of the purification member 11 and the inner surface of the fan cover 822. In this way, when the fresh air fan 6 operates, the cavity V0121 is in a negative pressure state, enabling the air flow to automatically flow into the cavity V0121 from the fresh air inlet 801, reducing the air flow resistance.

[0259] The cavity V0121 is equivalent to the air inlet negative pressure chamber of the fresh air fan 6, and the setting of the air inlet negative pressure chamber has many advantages:

[0260] First, improve the air inlet efficiency. For example, by setting the negative pressure chamber, the buffer space on the air suction side of the fresh air fan 6 is increased, making it easier for the fresh air fan 6 to suck air, thereby increasing the air intake of the fresh air fan 6. Moreover, due to the existence of the negative pressure chamber, the fresh air is buffered and adjusted in the negative pressure chamber before entering the fresh air fan 6, reducing the fluctuation and turbulence of the fresh air flow, which is beneficial to improving the air inlet stability of the fresh air fan 6. If there is no cavity V0121 and no buffer space, the flow resistance increases, and the operating power consumption of the fresh air fan 6 will rise.

[0261] Second, optimize the air flow distribution. For example, through the buffering and guiding of the negative pressure chamber, it is beneficial to guide the air flow to be sucked into the fresh air fan 6 along the axis.

[0262] Third, reduce the air flow impact and absorb noise.

[0263] In this way, while increasing the air intake of the fresh air device, it is beneficial to improve the overall air inlet reliability and stability.

[0264] In some embodiments, the fresh air volute 8 is further provided with an installation opening 803, and the purification member 11 is detachably assembled in the installation opening 803. This facilitates the disassembly of the purification member 11 when it is damaged or saturated, facilitating maintenance or replacement.

[0265] For example, as Figure 15 shown, the installation opening 803 is formed between the fan cover 822 and the second volute half 821, and the purification member 11 is detachably assembled in the fresh air chamber V012 through the installation opening 803. In this way, the size of the installation opening 803 can be set relatively large, facilitating the installation of a purification member 11 with a larger size. When the size of the installation opening 803 is large, the installation opening 803 is formed by enclosing between the fan cover 822 and the second volute half 821. The open half-ports are respectively formed on the fan cover 822 and the second volute half 821, which is convenient for processing or demolding, and the forming scrap rate is low.

[0266] For example, as Figure 3As shown, the mounting opening 803 is located on the front side of the main body 1000 in the front-to-back direction. When the purification element 11 is removed, it can be free from interference with the pipes connected to the fresh air inlet 801 and the exhaust outlet 902, thus facilitating removal. For example, a retractable panel (not shown) is provided on the front side of the housing 1. When the panel is opened or rotated upward, the mounting opening 803 is exposed, facilitating removal of the purification element 11.

[0267] It is also possible that in some solutions, the installation port 803 is set at the bottom of the main body 1000.

[0268] In some embodiments, as Figure 6 As shown, the fresh air volute 8 is formed with a purified air inlet 804 for communicating with the room. The fresh air fan 6 rotates to allow indoor air to enter the fresh air volute 8 from the purified air inlet 804 to be purified by the purification element 11, and allows the indoor air entering the fresh air volute 8 to enter the room from the fresh air outlet 802. In this way, the indoor air can enter the fresh air duct V01 from the purified air inlet 804, be purified, and then enter the room from the fresh air outlet 802.

[0269] This setup allows for the indoor air to circulate and purify when it becomes polluted. This purifies the indoor air, improving cleanliness, without the need for fresh air. Because no fresh air is introduced, the indoor air purification process prevents sudden influx of unheated cold or hot air from outside, preventing discomfort caused by sudden changes in indoor temperature.

[0270] For example, the accommodating cavity V1 in the housing 1 forms a first cavity V11 and a second cavity V12 through the internal structure. Figure 2 shown.

[0271] like Figure 4 In some of the embodiments shown, an end plate 31 is provided on the base 3 near the exhaust volute 9, the heat exchange fan 41 and the indoor heat exchanger 2 are located on one side of the end plate 31, and the exhaust volute 9 with the exhaust air inlet 901 is located on the other side of the end plate 31.

[0272] The arrangement of the first chamber V11 and the second chamber V12 here can also be directly formed by the housing 1 in other embodiments. For example, a partition is integrally formed in the housing 1 to separate the accommodating chamber V1 into the first chamber V11 and the second chamber V12.

[0273] At this time, at least a part of the second motor 5, the exhaust fan 7, the exhaust volute 9, and the fresh air volute 8 are located in the second chamber V12. For example, the purification air inlet 804 and the exhaust air inlet 901 are located on the same side of the air separation structure. When the fresh air fan 6 rotates, indoor air can enter the second chamber V12 from the heat exchange air inlet 101, and then enter the fresh air volute 8 from the purification air inlet 804 to be purified by the purification member 11, and the indoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. In this way, the purification air inlet 804 can be hidden in the second chamber V12, improving the aesthetic appearance of the wall-mounted air conditioner 10000. Moreover, there is no need to connect a physical pipeline between the purification air inlet 804 and the heat exchange air inlet 101, reducing the number of parts, the occupied volume, and facilitating the layout. For example, as Figure 6 shown, the purification air inlet 804 is located at the bottom of the fresh air volute 8 and is arranged with the direction facing downwards. It can be understood that the fresh air inlet 801 is located below the main body 1000, and both the fresh air inlet 801 and the purification air inlet 804 are located at the bottom of the fresh air volute 8 and extend in the downward direction, which is convenient for processing and forming. Moreover, in use, one of them is selected to be opened. At this time, both the fresh air inlet 801 and the purification air inlet 804 are placed at the bottom of the fresh air volute 8, which is convenient for centrally arranging switches to select one of the air inlets to be opened, reducing the number of switches.

[0274] In some embodiments, as Figure 6 shown, 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 by making the air inlet direction of the purification air inlet 804 perpendicular to the length direction of the heat exchange fan 41, the air suction area of the purification air inlet 804 is far from the exhaust air inlet 901, avoiding excessive air suction energy consumption caused by the purification air inlet 804 being too close to the exhaust air inlet 901. Moreover, the different directions of the purification air inlet 804 and the exhaust air inlet 901 help to expand the negative pressure area, which helps a large amount of indoor air to flow into the negative pressure area, ensuring the exhaust air volume and the indoor fresh air volume.

[0275] In some embodiments, as Figure 5 and Figure 8 shown, the exhaust volute 9 includes a wind guide ring 91, and the area surrounded by the wind guide ring 91 forms the exhaust air inlet 901. The setting of the wind guide ring 91 can effectively collect the dispersed air flow, converge it into a relatively concentrated air flow and send it to the exhaust fan 7, making the air inlet smoother and more efficient, and improving the air inlet volume of the exhaust fan 7.

[0276] Moreover, after the air guide ring 91 is reasonably designed in shape and angle, the air flow can enter the exhaust blades 72 of the exhaust fan 7 at an optimal angle, improving the working efficiency of the exhaust fan 7. When unstable air flow fluctuations are inhaled, the air guide ring 91 can play a role in stabilizing the air flow, reducing the turbulence and fluctuations of the air flow, enabling the exhaust fan 7 to operate more smoothly. It can reduce noise and vibration and extend the service life of the exhaust fan 7.

[0277] For example, the air guide ring 91 is in the shape of a circular tube and is easy to process.

[0278] For example, the diameter of the air guide ring 91 decreases in the direction towards the fresh air fan 6, and the diameter of the air guide ring 91 decreases in the direction towards the exhaust fan 7. As the diameter of the air guide ring 91 decreases, the passage for the air flowing through the air guide ring 91 becomes narrower. According to the principle of fluid mechanics, at the same flow rate, the narrowing of the passage will increase the air flow velocity, thereby increasing the wind speed and the air volume. The air guide ring 91 with a decreasing diameter is also beneficial for concentrating the relatively dispersed air volume upstream, making the air flow blow directly towards the center of the exhaust fan 7. When the air is gathered and then radially driven by the exhaust blades 72, it is more labor-saving, and the gathered air flow is also beneficial for the stability of the air flow.

[0279] For example, as Figure 8 shown, the exhaust fan 7 includes: an exhaust wheel disc 71 and exhaust blades 72. The exhaust wheel disc 71 is connected to the motor housing 53 of the second motor 5, and the exhaust blades 72 are connected to the side of the exhaust wheel disc 71 away from the fresh air fan 6. A plurality of exhaust blades 72 are arranged circumferentially along the exhaust wheel disc 71.

[0280] As Figure 8 and Figure 11 shown, the edge of the exhaust blade 72 away from the exhaust wheel disc 71 is the blade side edge 721, and at least part of the blade side edge 721 is a tapered section 7212. In the direction radially inwards of the exhaust fan 7, the distance between the tapered section 7212 and the exhaust wheel disc 71 decreases, and all the exhaust blades 72 form a side edge depression 73 at the tapered section 7212. The end of the air guide ring 91 is located within the side edge depression 73.

[0281] For example, the exhaust blades 72 of the exhaust fan 7 are concave blades, and both the air guide ring 91 and the concave blades are recessed towards the fresh air fan 6, and the air guide ring 91 partially enters the side edge depression 73 formed by the concave blades. With such a setting, the air guide ring 91 and the exhaust fan 7 can have partial overlap in the axial direction, and without increasing the axial dimension of the exhaust volute 9 on the premise of setting the air guide ring 91.

[0282] Moreover, after the exhaust fan 7 rotates, the surface swept by the exhaust blade 72 at the tapered section 7212 forms a funnel surface with a decreasing diameter, which is beneficial for the air flow to concentrate towards the center and reduce the energy loss caused by air flow disturbance.

[0283] In some embodiments, as Figure 17 As shown, the blade side edge 721 may include a straight section 7211, which is perpendicular to the axis of the exhaust fan 7 and connected to the end of the gradient section 7212 away from the axis of the exhaust fan 7. For example, the exhaust blade 72 has a larger axial dimension near the outer edge, which can fully utilize the space within the exhaust duct V02 to drive the airflow, thereby helping the airflow to obtain greater kinetic energy.

[0284] For example, the gradient section 7212 and the straight section 7211 are connected by a circular arc transition, and the gradient section 7212 and the surface of the exhaust disk 71 are also connected by a circular arc transition. This reduces stress concentration and the risk of fracture at the junctions between the gradient section 7212 and the straight section 7211, and between the gradient section 7212 and the surface of the exhaust disk 71. Furthermore, the circular arc transition between the gradient section 7212 and the surface of the exhaust disk 71 allows the transition to directly face the end of the air guide ring 91, reducing the risk of scratching.

[0285] In some embodiments, the revolving surfaces of the blade side edges 721 of all exhaust blades 72 overlap, and the revolving surface is the surface swept by the blade side edges 721 around the axis of the exhaust fan 7. In this way, when the airflow flows axially toward the center of the exhaust fan 7, excessive radial turbulence caused by the sweeping of individual exhaust blades 72 with inconsistent shapes is avoided, thereby improving the stability of the airflow.

[0286] For example, Figure 17 As shown, the axial spacing between the air guide ring 91 and the gradient section 7212 increases in the direction away from the axis of the exhaust fan 7. It is understandable that when the second motor 5 rotates to drive the exhaust fan 7, the exhaust fan 7 will inevitably produce a small amount of shaking due to wear. When the exhaust fan 7 shakes, the farther away from the axis of the exhaust fan 7, the greater the shaking amplitude. Therefore, increasing the axial spacing between the air guide ring 91 and the gradient section 7212 in the direction away from the axis of the exhaust fan 7 is beneficial to reducing the risk of friction caused by contact between the exhaust fan 7 and the air guide ring 91 during shaking.

[0287] In some embodiments, as Figure 17As shown, the axial dimension of the air guide ring 91 is Z1, which satisfies 2mm≤Z1≤12mm. It is understandable that when the axial dimension Z1 of the air guide ring 91 is less than 2mm, the flow path is too short when gathering, and the airflow enters the exhaust fan 7 before it is gathered. The gathering effect of the airflow is not obvious, and the airflow is easy to disperse. The exhaust fan 7 needs to consume more energy to introduce the dispersed airflow into the center. When the axial dimension Z1 of the air guide ring 91 is greater than 12mm, the air guide ring 91 occupies too much axial space in the exhaust volute 9, resulting in less space available to the exhaust fan 7, resulting in a reduction in the exhaust air volume. Therefore, the axial dimension Z1 of the air guide ring 91 is limited to between 2mm and 12mm, so that the air guide ring 91 gathers the airflow while ensuring that the exhaust fan 7 reaches a sufficient exhaust air volume, thereby achieving a larger exhaust air volume with lower power consumption.

[0288] For example, the axial dimension Z1 of the air guide ring 91 can be 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, 12 mm, etc.

[0289] For example, the axial dimension Z1 of the air guide ring 91 is 5 mm. Thus, the air guide ring 91 is more suitable for converging the airflow at the exhaust inlet 901, effectively converging the airflow. Furthermore, the air guide ring 91 does not excessively occupy the axial space within the exhaust volute 9, allowing the exhaust fan 7 to utilize a larger space, thereby ensuring that the exhaust fan 7 can achieve a sufficient exhaust air volume and achieve a larger exhaust air volume with lower power consumption.

[0290] In some embodiments, as Figure 17 As shown, the axial distance between the end of the air guide ring 91 and the exhaust blade 72 is Z2, which satisfies 1mm≤Z2≤5mm.

[0291] When the axial spacing Z2 between the end of the air guide ring 91 and the exhaust blades 72 is less than 1mm, the exhaust blades 72 are likely to collide with the air guide ring 91 during rotation, which not only generates friction loss, but also causes the exhaust fan 7 to be subjected to unbalanced force after the collision, potentially causing greater shaking and leading to a more serious collision. When the axial spacing Z2 between the end of the air guide ring 91 and the exhaust blades 72 is greater than 5mm, not only is the axial clearance between the end of the air guide ring 91 and the exhaust blades 72 wasteful, but the uncollected portion of the incoming air is likely to flow into the exhaust duct V02 from the axial clearance between the end of the air guide ring 91 and the exhaust blades 72. This unworked airflow will crowd out the flow path of the working airflow, reducing the operating efficiency of the exhaust fan 7.

[0292] Therefore, limiting the axial spacing Z2 between the end of the air guide ring 91 and the exhaust blade 72 to between 1 mm and 5 mm is beneficial for ensuring the reliability and efficiency of the exhaust fan 7. For example, the axial spacing Z2 between the end of the air guide ring 91 and the exhaust blade 72 can be 1 mm, 2.5 mm, 3 mm, 3.5 mm, 5 mm, etc.

[0293] For example, the axial distance Z2 between the end of the air guide ring 91 and the exhaust blade 72 can be 3 mm. In this way, the exhaust blade 72 is not likely to touch the air guide ring 91 during rotation, thus avoiding the greater shaking and more serious collision that may be caused by the unbalanced force on the exhaust fan 7 after the exhaust blade 72 collides with the air guide ring 91. At the same time, the axial clearance from the end of the air guide ring 91 to the exhaust blade 72 is not wasted too much. The amount of air flowing into the exhaust air duct V02 from the axial clearance from the end of the air guide ring 91 to the exhaust blade 72 is small, and more incoming air reaches the exhaust fan 7, ensuring the operating efficiency of the exhaust fan 7.

[0294] In some embodiments, as Figures 16 - 17 shown, the wall-mounted air conditioner 10000 may include: a fixed bracket 17 and a connecting arm 175. The fixed bracket 17 is located at the exhaust air inlet 901. In other words, the fixed bracket 17 is provided at the exhaust air inlet 901. The fixed bracket 17 is used to fix the second motor 5. The fixed bracket 17 is connected to the exhaust air volute 9 through a plurality of connecting arms 175, and the second motor 5 is installed on the fixed bracket 17. In this way, the fixed position of the second motor 5 has a small axial distance from the fresh air fan 6 and the exhaust fan 7, and the bending moment borne by the second motor 5 during operation is small, which is beneficial to improving the rotational stability of the fresh air fan 6 and the exhaust fan 7.

[0295] For example, as Figure 17 shown, the fixed bracket 17 includes a bracket end plate 171 and a bracket surrounding plate 172. The bracket surrounding plate 172 is formed by extending along the edge of the bracket end plate 171 in the direction towards the exhaust fan 7. The bracket end plate 171 is connected to the exhaust air volute 9. An installation cavity 174 is defined between the bracket surrounding plate 172 and the bracket end plate 171, and a part of the second motor 5 is accommodated in the installation cavity 174. For example, the fixed bracket 17 provides the installation cavity 174 with a simple structure, which not only increases the supporting area for the second motor 5, that is, both the bracket end plate 171 and the bracket surrounding plate 172 can support the second motor 5, improving the installation firmness of the second motor 5, but also the installation cavity 174 can protect the electronic connector at the end of the second motor 5.

[0296] For example, as Figure 17 shown, the bracket end plate 171 may be provided with a wire passing hole. The wire passing hole is assembled and connected to the wire harness of the second motor 5, and the connection part of the wire harness and the second motor 5 is located in the installation cavity 174. In this way, when introducing the wire harness connected to the second motor 5 from the outside, the wire harness can be directly introduced from the side of the fixed bracket 17 away from the exhaust fan 7. Compared with the scheme of leading the wire from other sides of the fixed bracket 17, the scheme provided by some embodiments is beneficial to reducing the length of the wire harness, avoiding the wire harness being too long and easily getting stuck in the exhaust fan 7, and the connection part of the wire harness and the second motor 5 is hidden in the installation cavity 174, which is not only beautiful but also can improve the reliability of the connection part, avoiding the situation of poor contact caused by the connection part being touched by foreign objects.

[0297] In some embodiments, referring to Figure 5 , the wall-mounted air conditioner 10000 may include: an insulating sleeve, which is sleeved on the wire harness and connected at the wire passing hole. The setting of the insulating sleeve buffers and protects the wire harness when it is connected to the wire passing hole, avoiding wire harness wear and resulting in electric leakage when this place is impacted. Moreover, to a certain extent, the insulating sleeve can seal the wire passing hole, reducing the entry of condensed water and moisture into the installation cavity 174 and reducing the risk of moisture and damage to the electronic connectors at the end of the second motor 5.

[0298] In some embodiments, at least one of the fresh air fan 6 and the exhaust fan 7 includes: a wheel disc and blades, the blades are connected to the wheel disc, and a transition fillet structure is provided at the connection between the blades and the wheel disc.

[0299] For example, the exhaust fan 7 includes: an exhaust wheel disc 71 and exhaust blades 72, the exhaust blades 72 are connected to one side of the exhaust wheel disc 71 away from the heat exchange fan 41, and the exhaust blades 72 are multiple and arranged circumferentially. A transition fillet structure is provided at the connection between the exhaust blades 72 and the exhaust wheel disc 71. This can reduce the concentrated stress at the connection between the exhaust blades 72 and the exhaust wheel disc 71 and improve the overall strength. In addition, when the air flow flows axially towards the exhaust wheel disc 71, the air flow can be guided by the transition fillet structure under the drive of the pressure difference, and there is less turbulence when the air flow turns, which is beneficial to reducing energy consumption.

[0300] For example, the fresh air fan 6 includes: a fresh air wheel disc 61 and fresh air blades 62, the fresh air blades 62 are connected to the fresh air wheel disc 61, and the fresh air blades 62 are multiple and arranged circumferentially. A transition fillet structure is provided at the connection between the fresh air blades 62 and the fresh air wheel disc 61. This can reduce the concentrated stress at the connection between the fresh air blades 62 and the fresh air wheel disc 61 and improve the overall strength. In addition, when the air flow flows axially towards the fresh air wheel disc 61, the air flow can be guided by the transition fillet structure under the drive of the pressure difference and flow more smoothly towards the fresh air blades 62, which is beneficial to reducing energy consumption.

[0301] In some embodiments, the accommodation cavity V1 in the housing 1 forms a first chamber V11 and a second chamber V12 through internal structure cooperation, as shown by the dashed line box in Figure 2 . The indoor heat exchanger 2 and the heat exchange fan 41 are located in the first chamber V11, and at least part of the two-way ventilation assembly is arranged in the second chamber V12. The heat exchange air inlet 101 and the heat exchange air outlet 102 on the housing 1 are correspondingly arranged for the first chamber V11, and a housing air outlet 105 can be provided on the housing 1 to communicate with the second chamber V12.

[0302] The rotation of the exhaust fan 7 allows indoor air to enter the first chamber V11 from the heat exchange air inlet 101. The air in the first chamber V11 can further enter the second chamber V12 and then enter the exhaust volute 9 from the exhaust air inlet 901.

[0303] In some embodiments, as Figure 18 shown, the base 3 includes: a first pedestal 301 and a second pedestal 302 arranged in sequence along the length direction of the heat exchange fan 41, and an end plate 31 is located between the first pedestal 301 and the second pedestal 302. A volute tongue air duct V03 is formed on the first pedestal 301. The indoor heat exchanger 2 and the heat exchange fan 41 are installed on the first pedestal 301, and the fresh air volute 8 and the exhaust volute 9 are installed on the second pedestal 302. For example, the two-way air exchange assembly is also installed on the base 3. Supported by the base 3, the overall integrity of the above structure is strong, which helps to avoid excessive vibration caused by loose parts.

[0304] For example, as Figure 5 and Figure 6 shown, at least one of the front ends of the fresh air volute 8 and the exhaust volute 9 is provided with a first hanging ear 806, and at least one of the rear ends of the fresh air volute 8 and the exhaust volute 9 is provided with a second hanging ear 807. The first hanging ear 806 and the second hanging ear 807 are respectively hung on the second pedestal 302, and the first hanging ear 806 and the second hanging ear 807 are detachably connected to the second pedestal 302. For example, when placing the fresh air volute 8 and the exhaust volute 9 on the second pedestal 302, then hanging the first hanging ear 806 and the second hanging ear 807 on the front end and the rear end of the second pedestal 302 respectively, and then fixing the first hanging ear 806 and the second hanging ear 807 on the second pedestal 302 with mounting bolts. With such a setting, not only is the assembly easy, but even if the bolts are loose, the fresh air volute 8 and the exhaust volute 9 are supported by the first hanging ear 806 and the second hanging ear 807 and will not fall.

[0305] For example, the first hanging ear 806 and the second hanging ear 807 are respectively provided with mounting holes for connecting the second pedestal 302, and there is an included angle between the axes of the mounting holes on the first hanging ear 806 and the second hanging ear 807. In this way, the contact surface between the first hanging ear 806 and the second pedestal 302 and the contact surface between the second hanging ear 807 and the second pedestal 302 have an included angle between the two contact surfaces, realizing double-sided limiting, not easy to loosen, and with higher positioning accuracy.

[0306] For example, as Figure 18 shown, the bottom of the second pedestal 302 is provided with a mating port 3021, and the lower ends of the fresh air volute 8 and the exhaust volute 9 are located at the mating port 3021. The mating port 3021 can be used to set the pipes connecting the fresh air volute 8 and the exhaust volute 9. This can not only greatly reduce the weight of the second pedestal 302, but also utilize the lower parts of the fresh air volute 8 and the exhaust volute 9 surrounded by the second pedestal 302 to improve the anti-impact and anti-vibration capabilities.

[0307] In some embodiments, in combination with Figure 2 and Figure 4 As shown, the wall-mounted air conditioner 10000 may include an electric control box 13, the electric control box 13 is located at a lateral end of the heat exchange fan 41, and the two-way ventilation assembly is located at the other lateral end of the heat exchange fan 41. For example, the two-way ventilation assembly and the electric control box 13 are located at the lateral two ends of the heat exchange fan 41, and the operation of the two-way ventilation assembly has less interference with the electric control box 13.

[0308] In some embodiments, the wall-mounted air conditioner 10000 may include an electric control box 13, the electric control box 13 and the two-way ventilation assembly are located at the same lateral end of the heat exchange fan 41, and the electric control box 13 is located on top of the two-way ventilation assembly. With such an arrangement, it is further beneficial to control the length of the wall-mounted air conditioner 10000.

[0309] In some embodiments, referring to Figure 6 , Figures 14 - 15 As shown, the wall-mounted air conditioner 10000 may further include: a fresh air valve 122, the fresh air valve 122 is installed inside the fresh air volute 8, and the fresh air valve 122 is used to open or close the fresh air inlet 801; when the fresh air valve 122 opens the fresh air inlet 801 and the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. When the fresh air valve 122 closes the fresh air inlet 801, outdoor air cannot enter the fresh air volute 8 from the fresh air inlet 801, and the air inside the fresh air volute 8 cannot be discharged to the outside from the fresh air inlet 801. By controlling the state of the fresh air valve 122, the opening or closing of the fresh air inlet 801 can be achieved.

[0310] By installing the fresh air valve 122 inside the fresh air volute 8, it is not necessary for the components outside the fresh air volute 8 to consider avoiding the fresh air valve 122. The action of the fresh air valve 122 opening and closing the fresh air inlet 801 will not touch the components outside the fresh air volute 8, and the fresh air volute 8 has a protective effect on the fresh air valve 122, which is beneficial to extending the service life of the fresh air valve 122.

[0311] In some embodiments, referring to Figure 6 , Figure 14As shown, the wall-mounted air conditioner 10000 may further include: an exhaust valve 152, which is installed inside the exhaust volute 9 and is used to open or close the exhaust air outlet 902; when the exhaust valve 152 opens the exhaust air outlet 902 and the exhaust fan 7 rotates, indoor air can enter the exhaust volute 9 from the exhaust air inlet 901, and the indoor air entering the exhaust volute 9 can be discharged to the outside through the exhaust air outlet 902. When the exhaust valve 152 closes the exhaust air outlet 902, the indoor air in the exhaust volute 9 cannot be discharged to the outside through the exhaust air outlet 902, and the outdoor air cannot enter the room through the exhaust air outlet 902. By controlling the state of the exhaust valve 152, the opening or closing of the exhaust air outlet 902 can be achieved.

[0312] By installing the exhaust valve 152 inside the exhaust volute 9, it is not necessary for the components outside the exhaust volute 9 to consider avoiding the exhaust valve 152. The opening and closing actions of the exhaust valve 152 for the exhaust air inlet 901 will not touch the components outside the exhaust volute 9, and the exhaust volute 9 has a protective effect on the exhaust valve 152, which is beneficial to extending the service life of the exhaust valve 152.

[0313] When the wall-mounted air conditioner 10000 is turned off, the wall-mounted air conditioner 10000 does not work. The fresh air valve 122 closes the fresh air inlet 801, and the exhaust valve 152 closes the exhaust air outlet 902 to prevent outdoor air from entering the room through the fresh air inlet 801 and the exhaust air outlet 902, and to prevent the indoor air from exchanging with the outdoor air through the two-way ventilation component.

[0314] In the related art, people's requirements for fresh air are constantly increasing, and the demand for fresh air volume is getting larger and larger. When the traditional air intake and exhaust module introduces outdoor fresh air into the room, it will also discharge the indoor air to the outside, resulting in large fluctuations in indoor temperature and affecting the user experience. When the two-way ventilation component of the wall-mounted air conditioner 10000 in this application is in the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, and the exhaust valve 152 closes the exhaust air outlet 902. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, outdoor air enters the fresh air duct V01 through the fresh air inlet 801, and then blows into the room through the fresh air outlet 802. The exhaust fan 7 only idles inside the exhaust volute 9. Since the exhaust duct V02 is closed at the exhaust air outlet 902, the air in the exhaust duct V02 does not flow, which will reduce the operating noise of the two-way ventilation component. At the same time, the indoor air cannot be discharged to the outside through the exhaust air outlet 902, resulting in small changes in indoor temperature and better user experience.

[0315] In the related art, people's requirements for fresh air are constantly increasing, and the demand for fresh air volume is getting larger. In low-temperature or high-temperature weather, such as in winter and summer, when outdoor fresh air is introduced into the room, due to the large temperature difference between indoor and outdoor air, the entry of outdoor fresh air into the room will cause large fluctuations in indoor temperature, affecting the user experience. When the two-way ventilation component of the wall-mounted air conditioner 10000 of the present application is in the exhaust mode, the fresh air valve 122 closes the fresh air inlet 801, and the exhaust valve 152 opens the exhaust outlet 902. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, indoor air enters the exhaust air duct V02 through the exhaust air inlet 901, and then blows to the outside through the exhaust air outlet 902. The fresh air fan 6 only idles in the fresh air volute 8. Since the fresh air duct V01 is closed at the fresh air inlet 801, the air in the fresh air duct V01 does not flow, which will reduce the operating noise of the two-way ventilation component. At the same time, the air in this room is discharged to the outside, and the air in this room is supplemented by the air in the remaining rooms. Since the temperature difference between the air in the remaining rooms and the air in this room is small, the indoor temperature changes little, and the user experience is better.

[0316] When the two-way ventilation component of the wall-mounted air conditioner 10000 is in the exhaust-fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, and the exhaust valve 152 opens the exhaust outlet 902. The exhaust-fresh air mode can be turned on when the temperature difference between indoor and outdoor air is small to meet the user's multi-scenario needs. At this time, when the second motor 5 drives the fresh air fan 6 and the exhaust fan 7 to rotate simultaneously, outdoor air enters the fresh air duct V01 through the fresh air inlet 801, and then blows into the room through the fresh air outlet 802. Indoor air enters the exhaust air duct V02 through the exhaust air inlet 901, and then blows to the outside through the exhaust air outlet 902.

[0317] In some embodiments, the two-way ventilation component has a fresh air inlet 801 and an exhaust outlet 902. The fresh air valve 122 is used to open or close the fresh air inlet 801, and the exhaust valve 152 is used to open or close the exhaust outlet 902. The wall-mounted air conditioner 10000 has a fresh air mode. In the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801 and the exhaust valve 152 closes the exhaust outlet 902.

[0318] In the exhaust mode, the fresh air valve 122 closes the fresh air inlet 801 and the exhaust valve 152 opens the exhaust outlet 902. [[ID=eleven]]

[0319] In the exhaust-fresh air mode, the fresh air valve 122 opens the fresh air inlet 801 and the exhaust valve 152 opens the exhaust outlet 902.

[0320] The wall-mounted air conditioner 10000 according to the embodiment of the present application can control the opening and closing of the fresh air inlet 801 by setting the fresh air valve 122, and can control the opening and closing of the exhaust air outlet 902 by setting the exhaust air valve 152, so that the fresh air and exhaust air processes of the wall-mounted air conditioner 10000 are controllable.

[0321] In some embodiments, referring to Figure 6 、 Figures 14 - 15 As shown, the wall-mounted air conditioner 10000 further includes a fresh air valve motor 121 and an exhaust air valve motor 151. The fresh air valve motor 121 is used to drive the fresh air valve 122 to translate, and the exhaust air valve motor 151 is used to drive the exhaust air valve 152 to translate. The axial direction of the fresh air valve motor 121 is parallel to the axial direction of the exhaust air valve motor 151.

[0322] In some embodiments, referring to Figure 6 、 Figure 15 As shown, the fresh air valve motor 121 includes a fresh air motor body 1211 and a fresh air motor shaft 1212. The fresh air motor body 1211 is installed outside the fresh air volute 8. In this way, 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, so as not to affect the air volume in the fresh air duct V01. The fresh air motor shaft 1212 is rotatably disposed in the fresh air motor body 1211. The fresh air motor shaft 1212 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 122 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. When the fresh air motor shaft 1212 rotates, it can drive the fresh air valve 122 to act, so that the fresh air valve 122 opens or closes the fresh air inlet 801.

[0323] In some embodiments, the fresh air valve 122 is a baffle. The fresh air valve motor 121 is used to drive the fresh air valve 122 to move. The moving direction of the fresh air valve 122 is perpendicular to the axial direction of the second motor 5, and the axial direction of the fresh air valve motor 121 is parallel to the axial direction of the second motor 5. Referring to Figures 1 - 4 、 Figure 6 、 Figure 15 As shown, the moving direction of the fresh air valve 122 is the front-back direction of the main body 1000, so that the space of the two-way ventilation component in the front-back direction of the main body 1000 can be fully utilized; the axial directions of both the fresh air valve motor 121 and the second motor 5 are the left-right direction of the main body 1000, which is convenient for the fresh air motor shaft 1212 to drive the fresh air valve 122 to move in the front-back direction.

[0324] In some embodiments, referring to Figures 1 - 4 、 Figure 6 、 Figure 15As shown, the air inlet direction of the fresh air inlet 801 is perpendicular to the axial direction of the fresh air valve motor 121, and the movement direction of the fresh air valve 122 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 from bottom to top, and the movement direction of the fresh air valve 122 is the front-to-back direction of the main body 1000. In this way, the fresh air valve 122 can open or close the fresh air inlet 801 within the shortest movement distance, which is beneficial to energy saving.

[0325] In some embodiments, reference Figure 6 、 Figure 15 As shown, the wall-mounted air conditioner 10000 also includes a fresh air transmission mechanism 123, the fresh air valve motor 121 and the fresh air valve 122 are connected to each other through the fresh air transmission mechanism 123, the fresh air transmission mechanism 123 includes 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, and the fresh air rack 1232 is fixed On the fresh air valve 122, the fresh air rack 1232 is fixed on the side of the fresh air valve 122 facing the fresh air gear 1231, so that the fresh air gear 1231 and the fresh air rack 1232 are directly engaged. The length direction of the fresh air rack 1232 is perpendicular to the axial direction of the second motor 5. The fresh air gear 1231 and the fresh air rack 1232 are engaged, so that the fresh air valve motor 121 drives the fresh air valve 122 to translate in the length direction of the fresh air rack 1232 when the fresh air gear 1231 rotates.

[0326] Specifically, the length direction of the fresh air rack 1232 is the front-to-back direction of the main body 1000, and the movement direction of the fresh air valve 122 is the same as the length direction of the fresh air rack 1232. 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 when the fresh air rack 1232 moves, it drives the fresh air valve 122 to move synchronously.

[0327] Optionally, the fresh air rack 1232 and the fresh air valve 122 can be connected by bolt assembly, welding, bonding, etc.; or optionally, the fresh air rack 1232 can also be integrally formed with the fresh air valve 122, which can reduce the assembly steps between the fresh air rack 1232 and the fresh air valve 122 and reduce the number of parts.

[0328] The fresh air transmission mechanism 123, which comprises a fresh air gear 1231 and a fresh air rack 1232, has a simple structure and reliable power transmission. Furthermore, the fresh air gear 1231 is directly mounted on the fresh air motor shaft 1212, eliminating the need for an intermediate transmission shaft. This simplifies the fresh air transmission mechanism 123 and reduces the number of components, space occupied, and cost.

[0329] In some embodiments, the fresh air inlet 801 is located on the second volute 82. The fresh air motor body 1211 is installed on the second volute 82, and the fresh air motor shaft 1212 at least partially extends into the interior of the second volute 82. The fresh air motor body 1211 is located outside the second volute 82, does not occupy the space inside the second volute 82, and does not affect the air volume inside the second volute 82. The part of the fresh air motor shaft 1212 extending into the interior of the second volute 82 is used to drive the fresh air valve 122 to open or close the fresh air inlet 801.

[0330] In some embodiments, the fresh air motor body 1211 is installed on the blower housing 822. Specifically, the fresh air motor body 1211 is installed outside the blower housing 822, does not occupy the space inside the blower housing 822, and does not affect the air volume inside the blower housing 822. The fresh air motor shaft 1212 extends into the interior of the blower housing 822.

[0331] In some embodiments, the fresh air gear 1231 is sleeved on the fresh air motor shaft 1212. A support hole may also be provided on the second volute half 821, and the end of the fresh air motor shaft 1212 extends into the support hole. Thus, the rotation of the fresh air motor shaft 1212 is more stable.

[0332] In some embodiments, referring to Figure 6 、 Figure 15 As shown, the blower housing 822 includes a housing plate 8222. The housing plate 8222 includes a housing plate body 82221 and a housing plate flange 82222. The housing plate flange 82222 is connected to the housing plate body 82221, and the housing plate flange 82222 protrudes downward relative to the housing plate body 82221. The housing plate flange 82222 extends downward relative to the housing plate body 82221 to the lower part of the main body 1000. The housing plate flange 82222 and the second volute half 821 enclose the fresh air inlet 801. By providing the housing plate flange 82222, it is convenient to connect the fresh air inlet pipe, and the fresh air inlet pipe can be separated from the housing plate body 82221. Optionally, the fresh air inlet pipe and the housing plate flange 82222 can be connected by means of a clamp, thread, etc.

[0333] The fresh air valve 122 is located on the side of the housing plate body 82221 facing away from the housing plate flange 82222. The side of the housing plate body 82221 facing away from the housing plate flange 82222 is the interior of the fresh air volute 8. In this way, the fresh air valve 122 is located inside the fresh air volute 8. Components outside the fresh air volute 8 do not need to consider avoiding the fresh air valve 122. The operation of opening and closing the fresh air inlet 801 by the fresh air valve 122 will not touch the components outside the fresh air volute 8, and the fresh air volute 8 has a protective effect on the fresh air valve 122, which is beneficial to extending the service life of the fresh air valve 122.

[0334] The fresh air valve 122 and the cover plate body 82221 are both configured as flat structures, and the fresh air valve 122 is parallel to the cover plate body 82221. When the fresh air valve 122 moves, it moves within a plane parallel to the cover plate body 82221, so as not to cause excessive interference to the air volume inside the fresh air volute 8.

[0335] In some embodiments, there are multiple positions where the fresh air valve 122 opens the fresh air inlet 801 to adjust the air volume at the fresh air inlet 801.

[0336] In some embodiments, referring to Figure 6 、 Figure 14 As shown, the wall-mounted air conditioner 10000 further includes an exhaust valve motor 151. The exhaust valve motor 151 includes an exhaust motor body 1511 and an exhaust motor shaft 1512. The exhaust motor body 1511 is installed outside the exhaust volute 9. In this way, the exhaust motor body 1511 does not occupy the internal space of the exhaust volute 9, nor does it occupy the space of the exhaust air duct V02, and thus does not affect the air volume in the exhaust air duct V02. The exhaust motor shaft 1512 is rotatably provided on the exhaust motor body 1511, and the exhaust motor shaft 1512 is used to drive the exhaust valve 152 to open or close the exhaust air outlet 902.

[0337] In some embodiments, the exhaust valve 152 is a baffle. The exhaust valve motor 151 is used to drive the exhaust valve 152 to move. The moving direction of the exhaust valve 152 is perpendicular to the axial direction of the second motor 5, and the axial direction of the exhaust valve motor 151 is parallel to the axial direction of the second motor 5. Referring to Figure 3 and Figure 14 As shown, the moving direction of the exhaust valve 152 is the front-back direction of the main body 1000, so that the space of the two-way ventilation component in the front-back direction of the main body 1000 can be fully utilized; the axial directions of both the exhaust valve motor 151 and the second motor 5 are the left-right direction of the main body 1000, which facilitates the exhaust motor shaft 1512 to drive the exhaust valve 152 to move in the front-back direction.

[0338] In some embodiments, referring to Figures 1 - 4 、 Figure 6 、 Figure 14 As shown, the air outlet direction of the exhaust air outlet 902 is perpendicular to the axial direction of the exhaust valve motor 151, and the moving direction of the exhaust valve 152 is perpendicular to the air outlet direction of the exhaust air outlet 902. Specifically, the air outlet direction of the exhaust air outlet 902 is the direction from top to bottom, and the moving direction of the exhaust valve 152 is the front-back direction of the main body 1000. In this way, the exhaust valve 152 can open or close the exhaust air outlet 902 within the shortest moving distance range, which is beneficial to energy conservation.

[0339] In some embodiments, referring to Figure 14As shown, the wall-mounted air conditioner 10000 also includes an exhaust transmission mechanism 153, and the exhaust valve motor 151 and the exhaust valve 152 are connected to each other through the exhaust transmission mechanism 153. The exhaust transmission mechanism 153 includes an exhaust gear 1531 and an exhaust rack 1532. The exhaust gear 1531 is engaged with the exhaust rack 1532, so that the exhaust valve motor 151 drives the exhaust valve 152 to translate in the length direction of the exhaust rack 1532 when the exhaust gear 1531 rotates.

[0340] The exhaust gear 1531 is located inside the exhaust volute 9. The exhaust gear 1531 is coaxially arranged with the exhaust motor shaft 1512. The exhaust motor shaft 1512 drives the exhaust gear 1531 to rotate. The exhaust rack 1532 is fixed on the exhaust valve 152, and the exhaust rack 1532 is fixed on the side of the exhaust valve 152 facing the exhaust gear 1531, so that the exhaust gear 1531 and the exhaust rack 1532 are directly engaged. The length direction of the exhaust rack 1532 is perpendicular to the axial direction of the second motor 5.

[0341] Specifically, the length direction of the exhaust rack 1532 is the front-to-back direction of the main body 1000, and the movement direction of the exhaust valve 152 is the same as the length direction of the exhaust rack 1532. When the exhaust gear 1531 rotates, it drives the exhaust rack 1532 to move along the length direction of the exhaust rack 1532, and when the exhaust rack 1532 moves, the exhaust valve 152 moves synchronously.

[0342] Optionally, the exhaust rack 1532 and the exhaust valve 152 can be connected by bolt assembly, welding, bonding, etc.; or optionally, the exhaust rack 1532 can also be integrally formed with the exhaust valve 152, which can reduce the assembly steps between the exhaust rack 1532 and the exhaust valve 152 and reduce the number of parts.

[0343] The exhaust transmission mechanism 153, which comprises an exhaust gear 1531 and an exhaust rack 1532, has a simple structure and reliable power transmission. Furthermore, the exhaust gear 1531 is directly mounted on the exhaust motor shaft 1512, eliminating the need for an intermediate transmission shaft. This simplifies the exhaust transmission mechanism 153 and reduces its component count, space requirements, and cost.

[0344] In some embodiments, the exhaust valve 152 opens the exhaust outlet 902 at multiple positions to adjust the air volume at the exhaust outlet 902.

[0345] In some embodiments, reference Figure 6 、 Figure 14As shown, the exhaust air volute 9 includes a main volute 92 and a secondary volute 93. The secondary volute 93 is detachably connected to the first volute 81, and the main volute 92 is adapted to be detachably connected to the first volute 81 and the secondary volute 93. The exhaust air valve motor 151 is installed on the secondary volute 93, and the exhaust air valve 152 is movably arranged in the space enclosed by the main volute 92 and the secondary volute 93. In this way, the relative position between the exhaust air gear 1531 and the exhaust air rack 1532 is easily adjusted. When the exhaust air valve motor 151 drives the exhaust air valve 152 to move, the power of the exhaust air valve motor 151 can be better transmitted to the exhaust air valve 152, and the exhaust air gear 1531 and the exhaust air rack 1532 will not get stuck, making the actions of opening and closing the exhaust air outlet 902 by the exhaust air valve 152 more reliable. Dividing the exhaust air volute 9 into at least the main volute 92 and the secondary volute 93 for separate processing can reduce the manufacturing and assembly difficulties, and for such a complex housing, it is convenient to carry out quality control after separate manufacturing. Detachably connecting the main volute 92 to the first volute 81, detachably connecting the secondary volute 93 to the first volute 81, and detachably connecting the main volute 92 to the secondary volute 93 is convenient for assembly and also convenient for subsequent adjustment and maintenance.

[0346] In some embodiments, referring to Figure 6 、 Figure 15 As shown, a purification air inlet 804 for communicating with the interior is formed on the cover plate body 82221. When the fresh air valve 122 opens the purification air inlet 804 and the fresh air fan 6 rotates, the indoor air can enter the fresh air volute 8 from the purification air inlet 804, and the indoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. That is to say, both the fresh air inlet 801 and the purification air inlet 804 are located on the cover plate body 82221, which is convenient for the fresh air valve 122 to block one of the purification air inlet 804 and the fresh air inlet 801 and open the other. By moving the fresh air valve 122, the fresh air valve 122 can block the purification air inlet 804 and open the fresh air inlet 801, or the fresh air valve 122 can block the fresh air inlet 801 and open the purification air inlet 804.

[0347] In some embodiments, the purification air inlet 804 and the fresh air inlet 801 are arranged at intervals along the moving direction of the fresh air valve 122. The air inlet directions of the purification air inlet 804 and the fresh air inlet 801 are the same, which facilitates the fresh air valve 122 to open one of the purification air inlet 804 and the fresh air inlet 801 and close the other when translating. Specifically, the fresh air valve 122 is adapted to translate in a direction perpendicular to the axis of the second motor 5 to block one of the purification air inlet 804 and the fresh air inlet 801 and open the other. Thus, by using one fresh air valve 122, the opening and closing states of the purification air inlet 804 and the fresh air inlet 801 can be switched, so that when one of the purification air inlet 804 and the fresh air inlet 801 is open, the other is in the closed state. There is no need to set two valves, saving the number of valves and the corresponding number of motors, which is beneficial to cost reduction.

[0348] The front-back direction of the main body 1000 is perpendicular to the direction of the axis of the second motor 5. In the front-back direction of the main body 1000, the purification air inlet 804 and the fresh air inlet 801 are arranged at intervals. For example Figure 6 、 Figure 15 As shown, the purification air inlet 804 can be located in front of the fresh air inlet 801, that is, the purification air inlet 804 is located on the side of the fresh air inlet 801 away from the wall. In some other embodiments, the purification air inlet 804 can also be located behind the fresh air inlet 801, that is, the purification air inlet 804 is located on the side of the fresh air inlet 801 close to the wall.

[0349] In some embodiments, referring to Figure 8 , the wall-mounted air conditioner 10000 further includes a purification member 11. The purification member 11 is installed in the fresh air chamber V012. The purification member 11 is connected to the second volute 82. When the fresh air valve 122 opens the fresh air inlet 801 and the fresh air fan 6 rotates, outdoor air can enter the fresh air volute 8 from the fresh air inlet 801, and the outdoor air entering the fresh air volute 8 can be blown through the purification member 11 and then enter the room from the fresh air outlet 802. When the fresh air valve 122 opens the purification air inlet 804 and the fresh air fan 6 rotates, indoor air can enter the fresh air volute 8 from the purification air inlet 804, be purified by the purification member 11, and the indoor air entering the fresh air volute 8 can enter the room from the fresh air outlet 802. The fresh air valve 122 alternatively opens the fresh air inlet 801 or the purification air inlet 804, thereby switching between the fresh air mode and the purification mode to meet different usage requirements of users.

[0350] In some embodiments, the fresh air inlet 801 and the purified air inlet 804 are both located at the bottom of the fresh air volute 8, so that air flows from bottom to top through the fresh air inlet 801 or the purified air inlet 804 into the interior of the fresh air volute 8. Furthermore, since the fresh air inlet 801 and the purified air inlet 804 are both located at the bottom of the fresh air volute 8, a single fresh air valve 122 can be used to achieve phased opening of the fresh air inlet 801 or the purified air inlet 804, thereby reducing the number of valves and saving costs.

[0351] In some embodiments, reference Figure 6 、 Figure 15 As shown, the fresh air valve 122 opens or closes the fresh air inlet 801 by translation, and the exhaust valve 152 opens or closes the exhaust outlet 902 by translation. Specifically, the fresh air volute 8 is provided with a fresh air inlet 801 and a purified air inlet 804. Both the fresh air inlet 801 and the purified air inlet 804 are provided at the bottom of the fresh air volute 8, and the opening direction of the fresh air inlet 801 and the purified air inlet 804 are both downward.

[0352] By configuring the fresh air valve 122 to open or close the fresh air inlet 801 by translation, the fresh air valve 122 can simultaneously open and close the fresh air inlet 801 and the purified air inlet 804. Specifically, the fresh air valve 122 opens the fresh air inlet 801 while simultaneously closing the purified air inlet 804, and closes the fresh air inlet 801 while simultaneously opening the purified air inlet 804. In this way, the fresh air inlet 801 and the purified air inlet 804 share the same fresh air valve 122, eliminating the need for separate valves at the fresh air inlet 801 and the purified air inlet 804. This reduces the number of valves, and the switching operation principle of the fresh air valve 122 between the fresh air inlet 801 and the purified air inlet 804 is simple and easy to operate.

[0353] In some embodiments, the two-way ventilation component has a fresh air inlet 801, a purified air inlet 804 and an exhaust outlet 902. The fresh air valve 122 is used to open one of the fresh air inlet 801 and the purified air inlet 804, and close the other of the fresh air inlet 801 and the purified air inlet 804. The exhaust valve 152 is used to open or close the exhaust outlet 902.

[0354] In some embodiments, the wall-mounted air conditioner 10000 also includes a fresh air valve motor 121 and an exhaust valve motor 151. The fresh air valve motor 121 is used to drive the fresh air valve 122 to move horizontally, and the exhaust valve motor 151 is used to drive the exhaust valve 152 to rotate. The axial direction of the fresh air valve motor 121 is perpendicular to the axial direction of the exhaust valve motor 151.

[0355] In some embodiments, the axial direction of the fresh air valve motor 121 is parallel to the axial direction of the second motor 5, such that the axial direction of the fresh air valve motor 121 is perpendicular to the length extension direction of the fresh air rack 1232. In this way, when the fresh air valve motor 121 rotates, the fresh air valve motor 121 can better drive the fresh air rack 1232 to translate along the length extension direction of the fresh air rack 1232, thereby driving the fresh air valve 122 to translate synchronously.

[0356] In some embodiments, the axial direction of the exhaust air valve motor 151 is perpendicular to the axial direction of the second motor 5. In this way, the exhaust air valve 152 can use the axis of the exhaust air valve motor 151 as the center line of rotation, so as to open or close the exhaust air outlet 902.

[0357] In some embodiments, the exhaust air valve 152 opens or closes the exhaust air outlet 902 by rotating. Setting the exhaust air valve 152 to open or close the exhaust air outlet 902 by rotating can save the occupied space of the exhaust air valve 152, so that the structure of the exhaust air volute 9 at the exhaust air outlet 902 does not have to be made very large, and the rotation action of the exhaust air valve 152 is simple and easy to implement.

[0358] In some embodiments, the wall-mounted air conditioner 10000 includes an exhaust air valve motor 151. The exhaust air valve motor 151 includes an exhaust air motor body 1511 and an exhaust air motor shaft 1512. The exhaust air motor body 1511 is installed outside the exhaust air volute 9, and the exhaust air motor shaft 1512 is rotatably disposed in the exhaust air motor body 1511. The exhaust air motor shaft 1512 is used to drive the exhaust air valve 152 to open or close the exhaust air outlet 902.

[0359] In some embodiments, the exhaust air valve 152 is a baffle, and the exhaust air valve motor 151 is used to drive the exhaust air valve 152 to rotate at the exhaust air outlet 902 to open or close the exhaust air outlet 902. Specifically, the exhaust air motor shaft 1512 at least partially extends into the exhaust air volute 9, and the exhaust air motor shaft 1512 is used to drive the exhaust air valve 152 to rotate at the exhaust air outlet 902.

[0360] Specifically, with reference to Figure 21 As shown, the exhaust air valve 152 is fixedly connected to the exhaust air motor shaft 1512. Optionally, the exhaust air valve 152 and the exhaust air motor shaft 1512 are an integral part, or optionally, the exhaust air valve 152 and the exhaust air motor shaft 1512 are fixedly connected through assembly.

[0361] In some embodiments, when the exhaust valve 152 rotates outwards, that is, rotates in the air outlet direction of the exhaust air outlet 902, the exhaust valve 152 opens the exhaust air outlet 902. In this way, when exhausting air at the exhaust air outlet 902, the wind force will not push the exhaust valve 152 to rotate in the reverse direction, but will keep the exhaust valve 152 in the open state.

[0362] The wall-mounted air conditioner 10000 has a fresh air mode, an exhaust-fresh air mode, an exhaust-purification mode, and a purification mode.

[0363] In the fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, closes the purification inlet 804, and the exhaust valve 152 closes the exhaust air outlet 902.

[0364] In the exhaust-fresh air mode, the fresh air valve 122 opens the fresh air inlet 801, closes and opens the purification inlet 804, and the exhaust valve 152 opens the exhaust air outlet 902.

[0365] In the exhaust-purification mode, the fresh air valve 122 opens the purification inlet 804, closes the fresh air inlet 801, and the exhaust valve 152 opens the exhaust air outlet 902.

[0366] In the purification mode, the fresh air valve 122 opens the purification inlet 804, closes the fresh air inlet 801, and the exhaust valve 152 closes the exhaust air outlet 902.
