Description

[0002] At present, most wall-mounted air conditioners are limited by volume and weight, and the functions that can be realized are relatively limited. Usually, they can only cool or heat the indoor air. After the user turns on the air conditioner for a long time, if they feel that the indoor air is dirty and stuffy, the general operation is to open the window for ventilation, which is rather troublesome for manual operation.

[0003] In the existing technical solutions, there are some fresh air air conditioners. The motor drives the fresh air fan of the fresh air module and the exhaust fan of the exhaust module to rotate, so that the fresh air module sucks fresh air from the outside, and the exhaust module discharges the indoor air. However, the number of fans is relatively large, which is not conducive to the installation and disassembly operations and will lead to a relatively high failure rate. Therefore, there is still room for improvement. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0087] The solution of this application introduces the structure of a wall-mounted air conditioner 10000.

[0088] Before that, the structure of a common air conditioner is introduced first. A common air conditioner is a split-type air conditioner, which includes an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected through pipelines to transfer refrigerant. The indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 41.

[0089] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan and a throttling element. The compressor, the outdoor heat exchanger, the throttling element 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 heating mode of the air conditioner.

[0090] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0091] 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.

[0092] In some embodiments, the outdoor heat exchanger further includes heat exchange fins to increase the contact area between the outdoor air and the refrigerant flowing through the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0093] 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, and the outdoor fan provides power for the flow of the outdoor air.

[0094] 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.

[0095] In some solutions, the air conditioner further includes 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 can execute a refrigeration mode or a heating mode.

[0096] 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 further includes 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.

[0097] 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 into the room, and the heat exchange fan 41 provides power for the flow of the indoor air.

[0098] The air conditioner further includes a control device, which is mainly used to control the operating frequency of the compressor and the opening degree of the throttling member. Some control devices can also control the rotational speed of the outdoor fan and the rotational speed of the heat exchange fan 41, etc. The control device is connected to the compressor, the throttling member, the outdoor fan, and the heat exchange fan 41 through a data line to transmit communication information.

[0099] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor, or 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.

[0100] 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 key drive).

[0101] A wall-mounted air conditioner 10000 proposed by the present utility model 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.

[0102] The wall-mounted air conditioner 10000 according to an embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0103] The wall-mounted air conditioner 10000 according to an embodiment of the present utility model, as Figure 1 and Figure 2 shown, includes: a main body 1000.

[0104] The main body 1000 includes: a housing 1. 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 structure of the wall-mounted air conditioner 10000.

[0105] 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 condensate, in some embodiments, the housing 1 is installed horizontally on the wall and forms a small angle with the horizontal plane.

[0106] Referring to Figure 3 and Figure 4, the main body 1000 further includes: an indoor heat exchanger 2, which is disposed in the accommodation cavity V1. As described above, the indoor heat exchanger 2 is a part of the refrigerant circuit, with refrigerant flowing inside, and is used to cool or heat the air flowing over the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is usually arranged to extend along the length direction of the casing 1. 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.

[0107] Referring to Figure 3 and Figure 4 , the main body 1000 further includes: a base 3, which is disposed in the accommodation cavity V1. The base 3 is an installation support structure inside the main body 1000, and the indoor heat exchanger 2 can be installed on the base 3. Specifically, a volute tongue air duct V03 is formed on the base 3, and 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.

[0108] Referring to Figure 4 , the main body 1000 further includes: a heat exchange fan 41, which is arranged in the volute tongue air duct V03. In the solution of the present application, the heat exchange fan 41 can be selected as 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 air supply range. Moreover, by using a cross-flow fan and arranging the cross-flow fan along the length direction of the main body 1000, 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.

[0109] Referring to Figure 4 , the main body 1000 further includes: a first motor 42, which is disposed in the accommodation cavity V1. The first motor 42 is used to drive the heat exchange fan 41 to rotate, so that heat exchange between the air inside the air conditioner and the indoor space can be carried out.

[0110] By providing a heat exchange air outlet 102 and a heat exchange air inlet 101 on the casing 1, when the heat exchange fan 41 operates, the indoor air is sucked into the casing 1 from the heat exchange air inlet 101, and after heat exchange with the indoor heat exchanger 2, the heat-exchanged air is sent to the indoor through the heat exchange air outlet 102.

[0111] Thus, the adjustment of the indoor environmental temperature is realized. The indoor heat exchanger 2 can be used as an evaporator to provide a cooling air flow towards the indoor space through 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 through the heat exchange air outlet 102.

[0112] In the solution of the present application, in the height direction of the main body 1000, the heat exchange air inlet 101 is located above the heat exchange air outlet 102, which facilitates air intake from above and air outlet from below. In the present application, the height direction of the main body 1000 is the up-and-down direction.

[0113] 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 consumption 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.

[0114] Refer 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 and prevent 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, reducing the process of the heat exchange air idling without participating in indoor heat exchange.

[0115] In some specific 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.

[0116] 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. 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.

[0117] In some other embodiments, the heat exchange air outlet 102 is located at the front side of the casing 1 and close to the bottom, or it can be said that the heat exchange air outlet 102 is located at the front lower corner of the casing 1. At this time, the heat exchange air blown out by the heat exchange air outlet 102 will flow downward while flowing forward. In this way, after the heat exchange air is sent to a certain distance, the heat exchange air can sink and fall on people or objects on the ground, enabling people or objects on the ground to be in a comfortable indoor environment as soon as possible.

[0118] In the solution of the present application, the heat exchange fan 41 is located on the side of the indoor heat exchanger 2 away 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 rotation, and is also a power driving part for air supply.

[0119] The heat exchange fan 41 is placed on the 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. A part of it is distributed to the air inlet side, so that the inhaled air can overcome the air resistance generated by the indoor heat exchanger 2 when flowing into the volute tongue air duct V03, and 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 transmission distance is relatively long.

[0120] In the solution of this application, as Figure 4 shown, the first motor 42 is located at one end of the main body 1000 in the length direction. This facilitates the installation and maintenance of the first motor 42, and the overall main body 1000 does not need to become too high or too thick due to the setting of the first motor 42. Here, the height direction of the main body 1000 is consistent with the up and down direction, and the thickness direction of the main body 1000 is consistent with the front and back direction.

[0121] In the solution of this application, the wall-mounted air conditioner 10000 further includes a second motor 5 (as Figure 8 shown), the second motor 5 is arranged in the accommodation cavity V1, and the second motor 5 is located at the other end of the main body 1000 in the length direction.

[0122] In this way, the first motor 42 and the second motor 5 are located at both ends of the main body 1000 in the length direction. On the one hand, the two motors are separated and the distance is far, so the electromagnetic interference between them is small. On the other hand, the two motors are arranged at both ends of the main body 1000 in the length direction, rather than in the thickness or height direction of the main body 1000, making the main body 1000 of the wall-mounted air conditioner 10000 slender in shape, with a slender, thin and light appearance.

[0123] Referring to Figure 8 , the wall-mounted air conditioner 10000 may further include: an integrated fan 60, and the second motor 5 drives the integrated fan 60 to rotate in the working state. In other words, the second motor 5 is used to provide power for the rotation of the integrated fan 60.

[0124] Referring to Figure 8 , Figures 11 - 16 , the integrated fan 60 may include: a fresh air fan part 6, the fresh air fan part 6 is a centrifugal fan part with axial air inlet and radial air outlet, and the fresh air fan part 6 is located on the side of the heat exchange fan 41 away from the first motor 42.

[0125] Referring to Figure 8 , Figures 11 - 16 , the integrated fan 60 may include: an exhaust fan part 7, the exhaust fan part 7 is a centrifugal fan part with axial air inlet and radial air outlet, and in the length direction of the main body 1000, the exhaust fan part 7 is located on the side of the fresh air fan part 6 facing the second motor 5.

[0126] The characteristics of the centrifugal fan unit itself include being structurally compact, having a large air volume, low noise, and the fan noise decreasing significantly when the rotational speed drops. Therefore, for the fresh air fan unit 6 and the exhaust air fan unit 7, a centrifugal fan unit with a smaller size can be selected to meet the large air volume requirement. The centrifugal fan unit has small vibration and noise, and is not prone to resonance with the indoor heat exchanger 2, effectively controlling the vibration and noise of the overall wall-mounted air conditioner 10000.

[0127] Both the fresh air fan unit 6 and the exhaust air fan unit 7 adopt centrifugal fan units, and the air directions of the fresh air fan unit 6 and the exhaust air fan unit 7 can be reasonably arranged. Specifically, the fresh air fan unit 6 takes in air axially and discharges air radially, and the exhaust air fan unit 7 takes in air axially and discharges air radially. The fresh air fan unit 6 and the exhaust air fan unit 7 take in air from both ends away from each other, and then after being driven, the fresh air and the exhaust air are both discharged radially. 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.

[0128] In some embodiments, the exhaust air fan unit 7 and the fresh air fan unit 6 are integrally formed. "Integrally formed" means that the exhaust air fan unit 7 and the fresh air fan unit 6 can be an integral part connected by welding or bonding, or can be an integral part formed by integral casting, injection molding, or machining.

[0129] Refer 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 unit 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. The rotation of the integrated fan 60 can cause outdoor air to enter the fresh air volute 8 from the fresh air inlet 801, and can cause the outdoor air entering the fresh air volute 8 to enter the room from the fresh air outlet 802.

[0130] Refer to Figures 5 - 8 , the wall-mounted air conditioner 10000 further includes: an exhaust air volute 9, located on the side of the fresh air volute 8 facing the second motor 5. An exhaust air duct V02 is formed inside the exhaust air volute 9. The exhaust air fan unit 7 is installed inside the exhaust air volute 9. An exhaust air inlet 901 and an exhaust air outlet 902 are formed on the exhaust air volute 9. The rotation of the integrated fan 60 can cause indoor air to enter the exhaust air volute 9 from the exhaust air inlet 901, and can cause the indoor air entering the exhaust air volute 9 to be discharged to the outside from the exhaust air outlet 902.

[0131] In the solution of this application, a fresh air volute 8 and a fresh air fan unit 6 form a fresh air module. The fresh air fan unit 6 is arranged in a fresh air duct V01 and is used to drive air flow to be inhaled from a fresh air inlet 801 and discharged into the room through a fresh air outlet 802. The operation of the fresh air fan unit 6 provides the power for the fresh air to flow. Thus, by setting the cooperation of the fresh air duct V01 and the fresh air fan unit 6, when the air in the room is relatively dirty or the air quality is average, the relatively fresh air outdoors can be driven into the indoor environment by the fresh air fan unit 6 to improve the air flow environment in the room.

[0132] In the solution of this application, an exhaust volute 9 and an exhaust fan unit 7 form an exhaust module. The exhaust fan unit 7 is arranged in an exhaust duct V02 and is used to drive air flow to be inhaled from an exhaust inlet 901 and discharged out of the room through an exhaust outlet 902. The operation of the exhaust fan unit 7 provides the power for the dirty air flow to flow.

[0133] Thus, by setting the cooperation of the exhaust duct V02 and the exhaust fan unit 7, when the air in the room is relatively dirty or the air quality is average, the dirty air flow in the indoor space can be sucked away and discharged by the exhaust fan unit 7. After the indoor air volume decreases in this way, fresh air will be inhaled from outdoors or from other rooms through doors and windows, etc., to reduce the dirtiness of the indoor air.

[0134] A second motor 5, an integrated fan 60, a fresh air volute 8 and an exhaust volute 9 form a two-way ventilation component, and the two-way ventilation component is arranged in a main body 1000. The two-way ventilation component can provide fresh air for the room and can discharge the indoor air outdoors.

[0135] It should be noted that the operation mode of the two-way ventilation component in the wall-mounted air conditioner 10000 can be set according to actual usage requirements. In some embodiments, the two-way ventilation component can simultaneously operate in a fresh air mode and an exhaust mode, that is, the fresh air duct V01 and the exhaust duct V02 can be opened simultaneously. While the dirty air flow in the room flows to the outdoor space, the fresh air outdoors can also enter the indoor space. Through the combination of the in-and-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.

[0136] Moreover, since while discharging the indoor air outdoors, fresh air outdoors is supplemented into the room to keep the indoor air volume sufficient, it is easier to suck away the indoor air. For example, when there are irritating gases (such as gases released by home improvement materials), gas leakage of gas or other gases in the room, the two-way ventilation component can be set to simultaneously operate in the fresh air mode and the exhaust mode 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 of this application has a larger purification flow rate per unit time, a higher ventilation efficiency, and a faster purification effect.

[0137] Moreover, when ventilating, 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 occupants due to the sudden rise or fall in temperature. Also, the position of the main body 1000 is relatively high, so the ventilation position will not cause discomfort due to being too close to people.

[0138] In some other 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.

[0139] In some embodiments, a two-way ventilation component is provided inside the wall-mounted air conditioner 10000, such as Figure 8 shown, the two-way ventilation component includes: a second motor 5, an integrated fan 60, a fresh air volute 8, and an exhaust volute 9. The second motor 5 drives the integrated fan 60 to rotate synchronously in the working state.

[0140] In this embodiment, the fresh air fan part 6 is a centrifugal fan part with axial air intake and radial air outlet, and the fresh air fan part 6 is located on the side of the heat exchange fan 41 away from the first motor 42.

[0141] In this embodiment, the exhaust fan part 7 is a centrifugal fan part with axial air intake and radial air outlet. In the length direction of the main body 1000, the exhaust fan part 7 is located on the side of the fresh air fan part 6 facing the second motor 5.

[0142] In this embodiment, as Figure 8 shown, a fresh air duct V01 is formed inside the fresh air volute 8, and the fresh air fan part 6 is installed inside the fresh air volute 8. As Figure 6 shown, a fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air volute 8. The rotation of the fresh air fan part 6 can make the outdoor air enter the fresh air volute 8 from the fresh air inlet 801, and can make the outdoor air entering the fresh air volute 8 enter the room from the fresh air outlet 802.

[0143] In this embodiment, as Figure 8 shown, 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 part 7 is installed inside the exhaust volute 9. An exhaust inlet 901 and an exhaust outlet 902 are formed on the exhaust volute 9. The rotation of the exhaust fan part 7 can make the indoor air enter the exhaust volute 9 from the exhaust inlet 901, and can make the indoor air entering the exhaust volute 9 be discharged to the outdoor from the exhaust outlet 902.

[0144] In this embodiment, the second motor 5 is located at the end of the main body 1000 in the length direction, and the axial direction of the second motor 5 is arranged along the length direction of the main body 1000. The second motor 5 is the common power source for the fresh air module and the exhaust air module of the two-way ventilation component. To ensure the operation of the fresh air module and the exhaust air module, the second motor 5 needs to have sufficient operating power to drive sufficient air volume to flow. Based on the power requirement of the second motor 5, the second motor 5 needs to have a sufficiently large size.

[0145] In this embodiment, on the premise that the size parameters of the second motor 5 are generally determined, when arranging the fresh air module and the exhaust air module 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. Among them, in this embodiment, both the fresh air fan part 6 and the exhaust air fan part 7 adopt centrifugal fan parts and are integrally formed to form an integrated fan 60. The integrated fan 60 is connected to the second motor 5, which not only saves the number of motors, but also keeps the two centrifugal fan parts arranged in layers along the axial direction of the second motor 5, that is, the two centrifugal fan parts are arranged in layers along the length direction of the main body 1000.

[0146] In this embodiment, the centrifugal fan part itself is relatively flat in the axial direction. The fresh air fan part 6 and the exhaust air fan part 7 are stacked in this way, which can reduce the overall occupied axial dimension and make the length of the main body 1000 not need to be too long. Since the integrated fan 60 is connected to the second motor 5, the fresh air fan part 6 and the exhaust air fan part 7 can keep rotating synchronously and their paces are consistent.

[0147] In this embodiment, the fresh air fan part 6 is arranged on the side of the exhaust air fan part 7 facing the indoor heat exchanger 2, which can reduce the cold or heat loss in the room and improve the comfort when the fresh air is blown into the room. Specifically, the fresh air module where the fresh air fan part 6 is located is close to the indoor heat exchanger 2. The fresh air inhaled from the outside can absorb the cold or heat released by the indoor heat exchanger 2 before being blown into the room, so that the fresh air is as close as possible to the indoor temperature before being blown into the room.

[0148] In this way, when the wall-mounted air conditioner 10000 cools down, the fresh air absorbs the cold of the indoor heat exchanger 2, and the temperature of the blown fresh air decreases, avoiding blowing the outdoor hot air directly into the room. When the wall-mounted air conditioner 10000 heats up, the fresh air absorbs the heat of the indoor heat exchanger 2, and the temperature of the blown fresh air rises, avoiding blowing the outdoor cold air directly into the room. And the exhaust air module where the exhaust air fan part 7 is located is far from the indoor heat exchanger 2, and the cold or heat absorbed from the indoor heat exchanger 2 after absorbing air from the room is less, and the cold or heat loss discharged to the outside is less.

[0149] In this embodiment, the fresh air fan unit 6 is arranged on the side of the exhaust fan unit 7 facing the indoor heat exchanger 2, and when the indoor heat exchanger 2 is cooled, the condensed water can also be reduced from entering the air duct. Specifically, the exhaust volute 9 of the exhaust module, its exhaust air inlet 901 takes in air from the room, and the exhaust fan unit 7 takes in air along the axial direction, so the exhaust air inlet 901 is located on the side of the exhaust volute 9 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 easily sucked into the exhaust duct V02 by the exhaust module, reducing the risk of water accumulation and bacterial growth in the exhaust duct V02. When the fresh air module rotates, the fresh air fan unit 6 takes in air from the outside, and at this time, the condensed water on the indoor heat exchanger 2 will not be sucked into the fresh air duct V01, reducing the risk of water accumulation and bacterial growth in the fresh air duct V01.

[0150] In addition, in this embodiment, the exhaust fan unit 7 is located on the side of the fresh air fan unit 6 away from the indoor heat exchanger 2. For the exhaust fan unit 7 that needs to take in air from the indoor room, the air intake energy consumption it needs to consume is also low. Specifically, when the wall-mounted air conditioner 10000 is cooling or heating, the heat exchange fan 41 operates to drive the indoor air intake to flow through the indoor heat exchanger 2. The exhaust fan unit 7 is located at the end of the main body 1000, and the air intake end of the exhaust fan unit 7 is far from the air intake end of the heat exchange fan 41. The exhaust fan unit 7 does not need to draw air from the air intake end of the heat exchange fan 41, and the air intake energy consumption of the exhaust fan unit 7 can be reduced, so that sufficient exhaust air volume can be guaranteed, and sufficient indoor air can flow through the indoor heat exchanger 2 to obtain sufficient heat exchange air, so that the overall energy consumption of the wall-mounted air conditioner 10000 will not be too high.

[0151] In this embodiment, the fresh air module and the exhaust module are effectively integrated, so that the two modules can reasonably utilize their respective structural characteristics and spatial characteristics to complete the flat design, which not only reduces the overall size and weight of the two-way ventilation assembly, but also makes the two-way ventilation assembly as a whole light and the air ducts do not interfere with each other. The two-way ventilation assembly is arranged at one end in the length direction of the main body 1000. Compared with the main body without a two-way heat exchange assembly, only the horizontal length is increased. The height and thickness of the main body 1000 can remain roughly unchanged or change little, so that the main body 1000 has a light and thin appearance. Hanging it on the wall will not affect the indoor space layout because it is too abrupt, and it will not be difficult to fix the wall-mounted air conditioner 10000 due to excessive weight, which reduces the risk of falling off the wall. The wall-mounted air conditioner 10000 is still a light and thin model as a whole. It is not only beautiful when hung on the wall, but also has controllable weight and is safe to use.

[0152] According to the wall-mounted air conditioner 10000 of the embodiment of the utility model, an integrated fan 60 is used to realize the ventilation function of sucking fresh air from the outside into the room and exhausting the indoor air to the outside. The number of fans is small, so that the steps for assembling or disassembling the fan and the second motor 5 are reduced, which simplifies the assembly and disassembly operations, saves labor hours, and helps to reduce the failure rate of the wall-mounted air conditioner 10000.

[0153] In some embodiments, reference Figures 11 - 12 The integrated fan 60 includes a fan barrel 70, and the fresh air fan unit 6 and the exhaust air fan unit 7 are connected through the fan barrel 70. In the axial direction of the integrated fan 60, a fan gap V06 is formed between the fresh air fan unit 6 and the exhaust air fan unit 7. By setting the fan gap V06, the fresh air fan unit 6 can be completely located in the fresh air volute 8, and the exhaust air fan unit 7 can be completely located in the exhaust air volute 9. When the integrated fan 60 rotates, the fresh air fan unit 6 is not easy to hit the fresh air volute 8, and the exhaust air fan unit 7 is not easy to hit the exhaust air volute 9, which is conducive to improving the service life of the integrated fan 60. When the second motor 5 drives the integrated fan 60 to rotate, the integrated fan 60 will jump a little. If the fan gap V06 is not set, the fresh air fan unit 6 and the exhaust air fan unit 7 are close to each other in the axial direction of the integrated fan 60 without gap, which will cause a part of the fresh air fan unit 6 to enter the exhaust air volute 9, or cause a part of the exhaust air fan unit 7 to enter the fresh air volute 8, affecting the effect of fresh air suction and turbid air exhaust. For example, when a part of the fresh air fan unit 6 enters the exhaust volute 9, the fresh air fan unit 6 rotates to easily bring the fresh air in the fresh air volute 8 into the exhaust volute 9, thereby causing the turbid air discharged to the outside to be mixed with the fresh air, resulting in a waste of fresh air. When a part of the exhaust fan unit 7 enters the fresh air volute 8, the exhaust fan unit 7 rotates to easily bring the turbid air in the exhaust volute 9 into the fresh air volute 8, thereby causing the fresh air entering the room to be mixed with turbid air, resulting in impure fresh air.

[0154] In some embodiments, in combination Figures 11 - 12 , the axial length of the fan gap V06 is a1, the outer diameter of the fan tube 70 is a2, and a1<a2. The axial length of the fan gap V06 refers to the minimum distance between the fresh air fan unit 6 and the exhaust air fan unit 7 in the axial direction of the integrated fan 60. Figures 11 - 16As shown, the fresh air fan unit 6 includes a fresh air impeller disk 61 and fresh air blades 62. The fresh air blades 62 are provided on the fresh air impeller disk 61, and the fresh air blades 62 extend along the axial direction of the fresh air impeller disk 61 in a direction away from the exhaust air fan unit 7. The exhaust air fan unit 7 includes an exhaust air impeller disk 71 and exhaust air blades 72. The exhaust air blades 72 are provided on the exhaust air impeller disk 71, and the exhaust air blades 72 extend along the axial direction of the exhaust air impeller disk 71 in a direction away from the fresh air fan unit 6. The surface of the fresh air impeller disk 61 facing the exhaust air impeller disk 71 is the fresh air impeller disk surface, and the surface of the exhaust air impeller disk 71 facing the fresh air impeller disk 61 is the exhaust air impeller disk surface. The fan gap V06 refers to the minimum distance between the fresh air impeller disk surface and the exhaust air impeller disk surface.

[0155] In some embodiments, the fresh air impeller disk surface and the exhaust air impeller disk surface are arranged in parallel, and the fan gap V06 refers to the distance between the fresh air impeller disk surface and the exhaust air impeller disk surface.

[0156] In some embodiments, a1 and a2 satisfy: 0.1 < a1 / a2. Refer to Figure 8 and Figure 16 As shown, 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 the direction of the heat exchange fan 41. A volute perforation 815 is provided in the central partial area of the first volute end plate 811. The fan cylinder 70 passes through the volute perforation 815. The fresh air fan unit 6 is located on the side of the first volute end plate 811 facing the heat exchange fan 41, and the exhaust air fan unit 7 is located on the side of the first volute end plate 811 away from the heat exchange fan 41. When a1 / a2 ≤ 0.1, a1 is too small, which will cause the distance between the fresh air fan unit 6 and the first volute end plate 811 to be too close, and the distance between the exhaust air fan unit 7 and the first volute end plate 811 to be too close. When the integrated fan 60 rotates, the fresh air fan unit 6 is likely to touch the first volute end plate 811, resulting in damage to the fresh air fan unit 6, and the exhaust air fan unit 7 is likely to touch the first volute end plate 811, resulting in damage to the exhaust air fan unit 7. By setting 0.1 < a1 / a2, a1 is not too small, so as to ensure that the distance between the fresh air fan unit 6 and the first volute end plate 811 is appropriate, and the distance between the exhaust air fan unit 7 and the first volute end plate 811 is appropriate. When the integrated fan 60 rotates, the fresh air fan unit 6 is not likely to touch the first volute end plate 811, and the exhaust air fan unit 7 is not likely to touch the first volute end plate 811, which is beneficial to improving the service life of the integrated fan 60.

[0157] In some embodiments, a1 and a2 satisfy: a1 / a2 < 0.4. When a1 / a2 ≥ 0.4, a1 is too large, which will cause the fresh air fan part 6 and the exhaust air fan part 7 to be at a relatively large distance. When ensuring the fresh air volume and the exhaust air volume, the axial lengths of the fresh air fan part 6 and the exhaust air fan part 7 cannot be too short, which makes the overall axial dimension of the integrated fan 60 too large and is not conducive to the axial thinning of the two-way ventilation component. By setting a1 / a2 < 0.4, a1 is not too large, so as to ensure that the distance between the fresh air fan part 6 and the exhaust air fan part 7 is appropriate, and the overall axial dimension of the integrated fan 60 is not too large, which is conducive to the axial thinning of the two-way ventilation component.

[0158] In some embodiments, a1 and a2 satisfy: 0.1 < a1 / a2 < 0.4. At this time, a1 is not too large and not too small, and it is not easy for the fresh air fan part 6 and the exhaust air fan part 7 to touch the first volute end plate 811. The overall axial dimension of the integrated fan 60 is relatively appropriate, which is conducive to the axial thinning of the two-way ventilation component.

[0159] In some embodiments, a1 satisfies: 6 mm ≤ a1. When a1 < 6 mm, a1 is too small, which will cause the distance between the fresh air fan part 6 and the first volute end plate 811 to be too close and the distance between the exhaust air fan part 7 and the first volute end plate 811 to be too close. When the integrated fan 60 rotates, the fresh air fan part 6 is likely to touch the first volute end plate 811, resulting in damage to the fresh air fan part 6, and the exhaust air fan part 7 is likely to touch the first volute end plate 811, resulting in damage to the exhaust air fan part 7. By setting 6 mm ≤ a1, a1 is not too small, so as to ensure that the distance between the fresh air fan part 6 and the first volute end plate 811 is appropriate and the distance between the exhaust air fan part 7 and the first volute end plate 811 is appropriate. When the integrated fan 60 rotates, the fresh air fan part 6 is not likely to touch the first volute end plate 811, and the exhaust air fan part 7 is not likely to touch the first volute end plate 811, which is conducive to improving the service life of the integrated fan 60.

[0160] In some embodiments, a1 satisfies: a1 ≤ 12 mm. When a1 > 12 mm, a1 is too large, which will cause the fresh air fan part 6 and the exhaust air fan part 7 to be at a relatively large distance. When ensuring the fresh air volume and the exhaust air volume, the axial lengths of the fresh air fan part 6 and the exhaust air fan part 7 cannot be too short, which makes the overall axial dimension of the integrated fan 60 too large and is not conducive to the axial thinning of the two-way ventilation component. By setting 6 mm ≤ a1, a1 is not too large, so as to ensure that the distance between the fresh air fan part 6 and the exhaust air fan part 7 is appropriate, and the overall axial dimension of the integrated fan 60 is not too large, which is conducive to the axial thinning of the two-way ventilation component.

[0161] In some embodiments, a1 satisfies: 6 mm ≤ a1 ≤ 12 mm. At this time, a1 is neither too large nor too small. It is not easy for the fresh air fan part 6 to touch the first volute end plate 811, and it is not easy for the exhaust air fan part 7 to touch the first volute end plate 811. The overall axial dimension of the integrated fan 60 is relatively appropriate, which is beneficial to the axial thinning of the two-way ventilation component.

[0162] Optionally, a1 can be 6 mm, 8 mm, 10 mm, 12 mm, etc., or other values between 6 mm and 12 mm, which will not be listed one by one here.

[0163] In some embodiments, as Figures 11 - 16 shown, the fresh air fan part 6 includes a fresh air wheel disc 61 and fresh air blades 62. The fresh air blades 62 are arranged on the fresh air wheel disc 61, and the fresh air blades 62 extend along the axial direction of the fresh air wheel disc 61 in a direction away from the exhaust air fan part 7. The blade cylinder formed after the fresh air blades 62 are arranged circumferentially is open towards the axial air inlet end, which is convenient for air flow to be inhaled, reduces the air suction resistance, and ensures the air intake volume of the fresh air. The fresh air blades 62 include single-layer centrifugal blades. In this way, under the condition of meeting the air volume, the structure of the fresh air fan part 6 is simple and the cost is low.

[0164] In some embodiments, as Figures 11 - 16 shown, the exhaust air fan part 7 includes an exhaust air wheel disc 71 and exhaust air blades 72. The exhaust air blades 72 are arranged on the exhaust air wheel disc 71, and the exhaust air blades 72 extend along the axial direction of the exhaust air wheel disc 71 in a direction away from the fresh air fan part 6. The exhaust air fan part 7 includes single-layer centrifugal blades. In this way, under the condition of meeting the small air volume, the structure of the exhaust air fan part 7 is simple and the cost is low. Moreover, the blade cylinder formed after the exhaust air blades 72 are arranged circumferentially is open towards the axial air inlet end, which is convenient for air flow to be inhaled, reduces the air suction resistance, and ensures the air intake volume of the exhaust air.

[0165] In some embodiments, referring to Figures 11 - 12 shown, a fan gap V06 is formed between the exhaust air wheel disc 71 and the fresh air wheel disc 61.

[0166] In some embodiments, there are multiple exhaust air blades 72, and the multiple exhaust air blades 72 are arranged circumferentially on the exhaust air wheel disc 71. Further, the exhaust air blades 72 are located at the edge of the exhaust air wheel disc 71. Compared with the scheme of arranging the exhaust air blades 72 at the center of the exhaust air wheel disc 71, arranging the exhaust air blades 72 at the edge of the exhaust air wheel disc 71 is more likely to generate eddy currents.

[0167] In some embodiments, referring to Figures 11 - 12 shown, the ends of the multiple exhaust air blades 72 away from the exhaust air wheel disc 71 are separated from each other, and no rim is provided, so that the overall weight of the exhaust air fan 7 can be reduced.

[0168] In some embodiments, one end of each of the plurality of exhaust blades 72 away from the exhaust wheel disc 71 is connected to the exhaust wheel rim. The exhaust wheel rim is separated from the exhaust wheel disc 71. An air passage gap is formed between two adjacent exhaust blades 72 and the exhaust wheel disc 71 and the exhaust wheel rim. The exhaust blades 72 can better push air to form a vortex. The exhaust wheel rim is used to increase the connection strength of the plurality of exhaust blades 72. When the exhaust fan 7 rotates, it prevents the end of the plurality of exhaust blades 72 away from the exhaust wheel disc 71 from having a relatively large displacement, so as to avoid breaking the root of the end of the exhaust blade 72 connected to the exhaust wheel disc 71.

[0169] In some embodiments, referring to Figures 11 - 12 As shown, there are a plurality of fresh air blades 62, and the plurality of fresh air blades 62 are arranged circumferentially on the fresh air wheel disc 61. Further, the fresh air blades 62 are located at the edge of the fresh air wheel disc 61. Compared with the scheme of arranging the fresh air blades 62 at the center of the fresh air wheel disc 61, arranging the fresh air blades 62 at the edge of the fresh air wheel disc 61 is more likely to generate a vortex.

[0170] In some embodiments, as Figures 11 - 12 shown, one end of each of the plurality of fresh air blades 62 away from the fresh air wheel disc 61 is connected through a first wheel rim 63. The first wheel rim 63 is separated from the fresh air wheel disc 61. An air passage gap is formed between two adjacent fresh air blades 62 and the fresh air wheel disc 61 and the first wheel rim 63. The fresh air blades 62 can better push air to form a vortex. The first wheel rim 63 is used to increase the connection strength of the plurality of fresh air blades 62. When the fresh air fan 6 rotates, it prevents the end of the plurality of fresh air blades 62 away from the fresh air wheel disc 61 from having a relatively large displacement, so as to avoid breaking the root of the end of the fresh air blade 62 connected to the fresh air wheel disc 61.

[0171] In some embodiments, one end of each of the plurality of fresh air blades 62 away from the fresh air wheel disc 61 is separated from each other without arranging a wheel rim, which can reduce the overall weight of the fresh air fan 6.

[0172] In some embodiments, referring to Figure 4 、 Figures 11 - 12 , the fan cylinder 70 includes a fan cylinder body 701 and a fan cylinder end plate 702. Both the fresh air wheel disc 61 and the exhaust wheel disc 71 are connected to the fan cylinder body 701. The fan cylinder end plate 702 is arranged at one end of the fan cylinder body 701 facing the heat exchange fan 41.

[0173] In some embodiments, referring to Figure 4 、 Figures 11 - 12 , in the axial direction of the integrated fan 60, the fan cylinder end plate 702 is located on the side of the fresh air wheel disc 61 facing the heat exchange fan 41, and the height that the fan cylinder end plate 702 protrudes axially from the fresh air wheel disc 61 is not greater than the height that the fresh air blade 62 protrudes axially from the fresh air wheel disc 61. Specifically, in Figure 12Among them, the height by which the fan cylinder end plate 702 protrudes axially from the fresh air wheel disc 61 is h4, and the height by which the fresh air blade 62 protrudes axially from the fresh air wheel disc 61 is h5, satisfying h4 < h5. In this way, the fan cylinder end plate 702 will not protrude outward beyond the outer end face of the fresh air blade 62, and the total axial dimension of the integrated fan 60 is defined by the axial two ends of the fresh air fan part 6 and the exhaust air fan part 7.

[0174] In some embodiments, referring to Figure 9 and Figure 10 , the second motor 5 includes: a stator part 51 and a rotor part 52, and 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, and an alternating magnetic field is generated after alternating current is passed through the coil. The rotor part 52 generates induction and rotates in the alternating magnetic field.

[0175] Optionally, the rotor part 52 can be a magnetic ring or a magnetic tile. The rotor part 52 is preferably a magnetic ring, so that magnetic leakage loss can be reduced, 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 ability is good, and the mechanical precision is higher.

[0176] 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. Selecting the outer rotor motor for the second motor 5 not only has a simple structure, but also because 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, which 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.

[0177] In addition, the rotor part 52 is located radially outside the stator part 51, with a larger heat dissipation area and better heat dissipation performance, which is beneficial to the stable operation of the second motor 5. And after being arranged like this, the diameter size of the second motor 5 can be controlled to be smaller, and it will not occupy the air flow channel space.

[0178] Referring 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.

[0179] 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 connection with external structures.

[0180] The second motor 5 further includes: an output shaft 532, which 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 towards the side of the heat exchange fan 41, and the other end of the output shaft 532 extends into the stator portion 51. That is to say, the main body 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.

[0181] It should be noted that when referring to "axial direction", "radial direction", and "circumferential direction" in the description of the internal structure of the two-way ventilation component, 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 surrounding the output shaft 532 is the circumferential direction.

[0182] In some embodiments, the fan cylinder 70 is sleeved on the radial outer side of the motor housing 53, and the fan cylinder 70 is fixedly connected to the motor housing 53. A part of the second motor 5 in the motor housing 53 is embedded in the fan cylinder 70, so that in the length direction of the main body 1000, the second motor 5 almost overlaps with the integrated fan 60, making the part of the integrated fan 60 located outside the second motor 5 in the axial direction less, and making the overall axial dimension of the two-way ventilation component close to the axial dimension of the second motor 5, so that the length dimension of the main body 1000 can be controlled.

[0183] Refer to Figure 8 As shown, the main body part of the second motor 5 is more located in the exhaust fan part 7 and the fan cylinder 70, rather than in the fresh air fan part 6, which can leave more air flow space for the fresh air duct V01 and is beneficial to the inhalation of fresh air. It can be understood that when the wall-mounted air conditioner 10000 is in the cooling state, the fresh air module inhales 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.

[0184] In this embodiment, the indoor air is discharged to the outside through the exhaust module. 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 air duct V02 by the second motor 5 and leaving more fresh air ducts V01 is beneficial to ensuring a larger fresh air volume.

[0185] Moreover, since the second motor 5 adopts 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 provided, and the fan cylinder 70 can be directly sleeved on the radial outer side 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. By simply fixedly connecting the fan cylinder 70 to the motor housing 53, connecting the fresh air fan part 6 to the fan cylinder 70, and connecting the exhaust fan part 7 to the fan cylinder 70, the exhaust fan part 7 and the fresh air fan part 6 can be arranged coaxially and stacked, and the two can rotate synchronously. 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.

[0186] In some embodiments, as Figure 8 and Figure 11 shown, a receiving groove V07 is formed at the center of the fan cylinder 70 in the radial direction, 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 housing 53 of the second motor 5 are received in the receiving groove V07. Specifically, the main body part (i.e., the stator part 51 and the rotor part 52) of the second motor 5 and the motor housing 53 can be placed at the center of the fan cylinder 70, which will not hinder the exhaust air flow and can make full use of the central space of the integrated fan 60, reducing the occupied space of the second motor 5 outside.

[0187] Moreover, after the fan cylinder 70 is sleeved outside the second motor 5, it has a protective effect and can also make the center of mass of the exhaust fan part 7 as close as possible to the center of the rotor part 52. As a result, the bending moment generated by the fresh air fan part 6 and the exhaust fan part 7 on the second motor 7 is small, the integrated fan 60 shakes less when rotating, the integrated fan 60 operates stably, and the energy consumption is low.

[0188] In some embodiments, as Figures 10 - 11 shown, the total axial thickness of the stator part 51, the rotor part 52, and the motor housing 53 is h3, and the axial thickness of the fresh air fan part 6 is h1, where h1 > h3. Specifically, the total axial thickness of the fresh air wheel disc 61 and the fresh air blades 62 on the fresh air fan part 6 is h1. In this way, it also ensures a relatively large fresh air volume, and the second motor 5 does not need to occupy too much air duct space.

[0189] In some embodiments, the total axial thickness of the stator portion 51, the rotor portion 52 and the motor housing 53 is h3, and the axial thickness of the exhaust fan portion 7 is h2, where h3 > h2. Specifically, the exhaust fan portion 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 can be understood that the second motor 5 needs to drive the integrated fan 60. 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 portion 51, the rotor portion 52 and the motor housing 53 is set to be greater than the axial thickness of the main body portion of the exhaust fan portion 7 to ensure that the second motor 5 can support the rotation of the integrated fan 60 and improve the sufficient supporting force of the second motor 5.

[0190] In some embodiments, the axial thickness of the exhaust fan portion 7 is h2, and the axial thickness of the fresh air fan portion 6 is h1, where h2 < h1. As Figure 11 shown, on the exhaust fan portion 7, the total axial thickness of the exhaust wheel disc 71 and the exhaust blades 72 is h2, and on the fresh air fan portion 6, the total axial thickness of the fresh air wheel disc 61 and the fresh air blades 62 is h1, where 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 portion 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 portion 7 is small, and the smaller axial thickness of the main body portion can appropriately reduce the exhaust air volume and at the same time reduce the axial dimension of the two-way ventilation component.

[0191] 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 141 (as Figure 2 shown). The fresh air introduction pipe 141 can be a part of the wall-mounted air conditioner 10000, or can be a fresh air introduction pipe 141 additionally configured by the user after purchasing the wall-mounted air conditioner 10000.

[0192] The fresh air inlet 801 is arranged below the main body 1000. In this way, the fresh air inlet pipe 141 can be connected to the fresh air inlet 801 from below, and the connection part extends generally in the vertical direction instead of in the front-rear 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 unit 6 is installed is circular. Based on the fact that the axis of the fresh air volute 8 extends along the length direction of the main body 1000, there is free space on both the front side and the rear side at the bottom of this circle. This part of the space can be used to arrange the fresh air inlet 801 to connect the fresh air inlet pipe 141. Thus, the connection part between the fresh air inlet pipe 141 and the fresh air inlet 801 can be placed in this free space without occupying additional space, so as to control the height dimension of the main body 1000.

[0193] In the solution of this application, 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 pipe to guide the indoor air to the outside. Here, this pipe is called the exhaust air outlet pipe 142 (as Figure 2 shown). The exhaust air outlet pipe 142 can be a part of the wall-mounted air conditioner 10000, or an exhaust air outlet pipe 142 additionally configured by the user after purchasing the wall-mounted air conditioner 10000.

[0194] The exhaust air outlet 902 is arranged below the main body 1000. In this way, the exhaust air outlet pipe 142 can be connected to the exhaust air outlet 902 from below, and the connection part extends generally in the vertical direction instead of in the front-rear 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 exhaust air volute 9 where the exhaust air fan unit 7 is installed is circular. Based on the fact that the axis of the exhaust air volute 9 extends along the length direction of the main body 1000, there is free space on both the front side and the rear side at the bottom of this circle. And based on the characteristics that the exhaust air fan unit 7 has axial air inlet and radial air outlet, the volute tongue of the exhaust air volute 9 can be arranged generally in the vertical direction and can be placed in the front-side or rear-side free space mentioned above.

[0195] Here, the exhaust air outlet 902 is arranged to connect the exhaust air outlet pipe 142. Thus, the connection part between the exhaust air outlet pipe 142 and the exhaust air outlet 902 can be placed in this free space without occupying additional space, so as to control the height dimension of the main body 1000.

[0196] In some specific embodiments, such as Figure 2As shown, the wall-mounted air conditioner 10000 further includes: a fresh air inlet pipe 141 connected to the fresh air inlet 801, and an exhaust outlet pipe 142 connected to the exhaust outlet 902. An avoidance opening 104 for the pipes is provided on the bottom wall of the housing 1. The fresh air inlet pipe 141 and the exhaust outlet pipe 142 pass through the avoidance opening 104 for the pipes and extend out of the main body 1000 from below. The fresh air inlet pipe 141 and the exhaust outlet pipe 142 are two independent pipe components, which helps to separate the fresh air flow path and the exhaust air flow path from each other, without intersection, and reduces the risk of air leakage caused by cross-flow.

[0197] The avoidance opening 104 for the pipes is provided on the bottom wall of the main body 1000, which facilitates the installation of the above pipes and ensures the aesthetic appearance of the main body 1000. The fresh air inlet pipe 141 and the exhaust outlet pipe 142 are connected from below the main body 1000, without affecting the upper area after the wall-mounted air conditioner 10000 is hung on the indoor wall, that is, the fresh air inlet pipe 141 and the exhaust outlet pipe 142 will neither interfere with the rear wall nor with the upper roof. The wall-mounted air conditioner 10000 is more convenient and fast to install.

[0198] Further, the air inlet direction of the fresh air inlet 801 is set upward. Specifically, the air inlet direction of the fresh air inlet 801 is perpendicular to the length direction of the main body 1000. In this way, after the two-way ventilation component is provided at the end of the wall-mounted air conditioner 10000, when the fresh air inlet pipe 141 is connected to the fresh air inlet 801, the fresh air inlet pipe 141 will not cause the overall length of the wall-mounted air conditioner 10000 to be overly elongated. Furthermore, the fresh air inlet 801 is located at the bottom of the main body 1000 and close to the rear side. In this way, after the fresh air inlet pipe 141 is connected to the fresh air inlet 801, it is convenient for the fresh air inlet pipe 141 to be arranged close to the wall.

[0199] Further, the air outlet direction of the exhaust outlet 902 is set downward. Specifically, the air outlet direction of the exhaust outlet 902 is perpendicular to the length direction of the main body 1000. In this way, after the two-way ventilation component is provided at the end of the wall-mounted air conditioner 10000, when the exhaust outlet pipe 142 is connected to the exhaust outlet 902, the exhaust outlet pipe 142 will not cause the overall length of the wall-mounted air conditioner 10000 to be overly elongated. Furthermore, the exhaust outlet 902 is located at the bottom of the main body 1000 and close to the rear side. In this way, after the exhaust outlet pipe 142 is connected to the exhaust outlet 902, it is convenient for the exhaust outlet pipe 142 to be arranged close to the wall.

[0200] Of course, the solution of the present application is not limited to this, such as Figure 1As shown, the pipe guiding avoidance opening 104 can also be arranged on the side wall of the casing 1. After the fresh air inlet pipe 141 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 guiding avoidance opening 104 on the side wall of the casing 1, and then extends to the outside. After the exhaust outlet pipe 142 is connected to the exhaust outlet 902 from below the main body 1000, it bends and extends horizontally, then extends out from the pipe guiding avoidance opening 104 on the side wall of the casing 1, and then extends to the outside.

[0201] It can be understood that a refrigerant pipe and a 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 outdoor compressor and outdoor heat exchanger, and the drain pipe is used to discharge the condensed water generated in the wall-mounted air conditioner 10000.

[0202] The pipe guiding avoidance opening 104 is arranged on the side wall of the casing 1, and then the fresh air inlet pipe 141 and the exhaust outlet pipe 142 are arranged horizontally and then led out, which is convenient for arranging at least one of the fresh air inlet pipe 141 and the exhaust outlet pipe 142 side by side with the drain pipe and the refrigerant pipe. Then, the juxtaposed multiple pipes are covered by an outer bundle pipe or a band, so that the multiple pipes are in the shape of 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, which not only facilitates assembly but also avoids the risk of multiple pipes bumping.

[0203] 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 arranged along the length direction of the main body 1000. That is to say, the exhaust air inlet 901 faces the axial air inlet end of the exhaust air fan part 7, so that the air inlet resistance of the exhaust air fan part 7 from the exhaust air inlet 901 is small, which is beneficial to ensuring the exhaust air intake. When the exhaust air intake is relatively easy, a smaller-sized exhaust air fan part 7 can be selected to further reduce the size of the two-way ventilation component.

[0204] In some embodiments, the area of the outer circular surface of the fresh air fan part 6 is S1, and the area of the outer circular surface of the exhaust air fan part 7 is S2, satisfying S1 > S2. Among them, S1 = πD1*h1, where D1 is the outer diameter of the fresh air fan part 6 and h1 is the thickness of the fresh air fan part 6. The outer diameter D1 of the fresh air fan part 6 refers to the maximum distance of the connection line between two points on the fresh air fan part 6 along the radial direction of the integrated fan 60 and passing through the axis of the integrated fan 60. The fresh air fan part 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 extend along the axial direction of the fresh air wheel disc 61. The thickness of the fresh air fan part 6 is the total thickness of the fresh air wheel disc 61 and the fresh air blades 62 in the axial direction, which is h1. Here, the fresh air wheel disc 61 on the fresh air fan part 6 can be one or at least two axially spaced apart. On each side of the axial direction of each fresh air wheel disc 61, only one circle of fresh air blades 62 can be provided on one side, or one circle of fresh air blades 62 can be provided on each side. When all the fresh air wheel discs 61 and fresh air blades 62 are projected vertically on the axis of the fresh air fan part 6, the distance between the two farthest points in the projection is equal to h1.

[0205] S2 = πD2*h2, where D2 is the outer diameter of the exhaust air fan part 7 and h2 is the thickness of the exhaust air fan part 7. The outer diameter D2 of the exhaust air fan part 7 refers to the maximum distance of the connection line between two points on the exhaust air fan part 7 along the radial direction of the integrated fan 60 and passing through the axis of the integrated fan 60. The exhaust air fan part 7 includes an exhaust air wheel disc 71 and exhaust air blades 72. The exhaust air blades 72 are located at the outer edge of the exhaust air wheel disc 71 and extend along the axial direction of the exhaust air wheel disc 71. The thickness of the exhaust air fan part 7 is the total thickness of the exhaust air wheel disc 71 and the exhaust air blades 72 in the axial direction, which is h2. Here, the exhaust air wheel disc 71 on the exhaust air fan part 7 can be one or at least two axially spaced apart. On each side of the axial direction of each exhaust air wheel disc 71, only one circle of exhaust air blades 72 can be provided on one side, or one circle of exhaust air blades 72 can be provided on each side. When all the exhaust air wheel discs 71 and exhaust air blades 72 are projected vertically on the axis of the exhaust air fan part 7, the distance between the two farthest points in the projection is equal to h2.

[0206] With such a setting, the area of the outer circular surface of the fresh air fan part 6 is large, and the area of the outer circular surface of the exhaust air fan part 7 is small, which is beneficial to achieving a large fresh air volume under the condition of limited overall machine space size.

[0207] Optionally, according to the structural and functional requirements designed in this application, the outer diameter D1 of the fresh air fan part 6 is greater than the outer diameter D2 of the exhaust air fan part 7, which is beneficial to making the area swept by the fan blades of the fresh air fan part 6 when rotating larger than the area swept by the fan blades of the exhaust air fan part 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 indoors, 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 indoor is more conducive to supplementing fresh air in the indoor space, supplementing the oxygen content and reducing the carbon dioxide content in the indoor air.

[0208] Moreover, by setting the outer diameter D2 of the exhaust air fan part 7 to be smaller than the outer diameter D1 of the fresh air fan part 6, it is easy to arrange the exhaust air outlet 902 of the exhaust air duct V02 and the fresh air outlet 802 of the fresh air duct V01 to be misaligned on the outer periphery of the two-way ventilation component. On the one hand, it is convenient to connect the exhaust air lead-out pipe 142 to the exhaust air outlet 902 and the fresh air inlet pipe 141 to the fresh air outlet 802. On the other hand, it is easy to ensure that the flow paths of the fresh air and the exhaust air in the two-way ventilation component do not cross.

[0209] Correspondingly, the outer diameter of the exhaust air volute 9 is smaller than the outer diameter of the fresh air volute 8. In this way, it is easy to arrange the exhaust air outlet 902 of the exhaust air duct V02 and the fresh air outlet 802 of the fresh air duct V01 to be misaligned on the outer periphery of the two-way ventilation component, facilitating the connection of the exhaust air lead-out pipe 142 to the exhaust air outlet 902 and the fresh air inlet pipe 141 to the fresh air outlet 802, and avoiding interference caused by the too-close distance between the two pipe joints, which is not only convenient for assembly but also for sealing.

[0210] In addition, by setting the outer diameter of the exhaust air volute 9 to be relatively small, more space can be vacated on the outer side of the exhaust air volute 9 in the radial direction, enabling air to flow in the space inside the casing 1 on the radial outer side of the exhaust air volute 9. In this way, when the exhaust air volute 9 inhales air from the exhaust air inlet 901, more air can enter, which is beneficial to increasing the exhaust air intake volume.

[0211] In some embodiments, referring to Figure 5 and Figure 17 , 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 air volute 9 facing the heat exchange fan 41 and is detachably connected to the exhaust air volute 9. The second volute 82 is located on the side of the first volute 81 facing the heat exchange fan 41 and is detachably connected to the first volute 81. The first volute 81 is located between the exhaust air volute 9 and the second volute 82.

[0212] In this application, the fresh air volute 8 is axially divided into at least a first volute 81 and a second volute 82 for separate processing, which can reduce the manufacturing and assembly difficulties. Moreover, for such a complex housing, separate manufacturing facilitates quality control. The first volute 81 is detachably connected to the exhaust air volute 9, and the second volute 82 is detachably connected to the first volute 81, which is convenient for assembly and subsequent adjustment and maintenance.

[0213] In some embodiments, referring to Figure 5 , Figure 8 and Figure 17 , the second volute 82 includes: a second volute half 821 and a fan cover 822. The second volute half 821 is located on the side of the first volute 81 facing the heat exchange fan 41 and is detachably connected to the first volute 81. The second volute half 821 is provided with an axial ventilation opening 8211 at the center in the radial direction. A volute cavity V011 is formed between the second volute half 821 and the first volute 81. The fresh air fan part 6 is located in the volute cavity V011, and the axial air inlet end of the fresh air fan part 6 is arranged facing the axial ventilation opening 8211. The second volute half 821 and the first volute 81 enclose a fresh air outlet 802.

[0214] The fan cover 822 is located on the side of the second volute half 821 facing the heat exchange fan 41 and is detachably connected to the second volute half 821. The cavity enclosed by the fan cover 822 and the second volute half 821 is the fresh air cavity V012, and the fan cover 822 and the second volute half 821 enclose a fresh air inlet 801.

[0215] After such an arrangement, 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 vertically enter the fresh air fan 6 axially from the fresh air cavity V012, thereby improving the air suction efficiency of the fresh air fan 6 and reducing the air suction loss.

[0216] Among them, the fan cover 822 is located on the side of the second volute half 821 facing the indoor heat exchanger 2, so that the volute cavity V011 can be spaced apart from the indoor heat exchanger 2. When the indoor heat exchanger 2 refrigerates, the indoor heat exchanger 2 can absorb the heat in the fresh air cavity V012, gradually reducing the fresh air temperature. And due to the interval of the fan cover 822, the indoor heat exchanger 2 is far from the volute cavity V011, and the cooling capacity of the indoor heat exchanger 2 to the air in the volute cavity V011 decreases, and the air in the volute cavity V011 is not likely to be supercooled to generate condensed water.

[0217] In this way, even if the inhaled fresh air is cooled, it will not be too cold to generate condensed water. Moreover, even if condensed water is generated in the fresh air chamber V012, the condensed water is likely to remain in the fresh air chamber V012 and is not likely to enter the volute chamber V011 and then be blown into the room, avoiding the situation of water blowing from the fresh air module. When the indoor heat exchanger 2 is heating, the indoor heat exchanger 2 can absorb the cold in the fresh air chamber V012, gradually increasing the temperature of the fresh air. Subsequently, the heated air enters the volute chamber V011 and is fully mixed, making the hot air blown out from the fresh air module milder.

[0218] In some embodiments, referring to Figure 3 , the wall-mounted air conditioner 10000 further includes: a purification component 11, referring to Figure 8 , the purification component 11 is provided in the fresh air duct V01, so that the fresh air blown into the room is purified, improving the cleanliness of the indoor air.

[0219] Specifically, the purification component 11 is installed in the fresh air chamber V012, that is to say, the purification component 11 is located at the axial air inlet end of the fresh air fan part 6. The rotation of the fresh air fan part 6 can enable outdoor air to enter the fresh air volute 8 from the fresh air inlet 801, and can enable the outdoor air entering the fresh air volute 8 to blow through the purification component 11 and then enter the room from the fresh air outlet 802.

[0220] In this way, the fresh air flow can almost vertically blow through the purification component 11, further reducing the fresh air inlet consumption, thereby increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in the cooling state and condensed water is generated in the fresh air, the condensed 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 module blows out air.

[0221] Furthermore, the purification component 11 is connected to the second volute 82, so that the assembly of the purification component 11 is convenient and there is no interference with the fresh air fan part 6.

[0222] Optionally, 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 part 6. The filter net 111 has a large coverage area, a large filtering area, and a good filtering effect. The setting of the filter net 111 helps to ensure sufficient contact area with the flowing air, and has a light weight and low air passing noise. Optionally, 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.

[0223] Optionally, the filter net 111 is plate-shaped, so that the filter net 111 is relatively thin as a whole and will not occupy too thick a size when placed in the two-way ventilation component.

[0224] Optionally, the filter net 111 is square, so that the positioning and installation of the filter net 111 are convenient.

[0225] Furthermore, the filter screen 111 is a square mesh, and the side length of the filter screen 111 is greater than the diameter of the axial ventilation opening 8211. The square mesh is convenient for positioning during fixation, is not easily shaken after fixation, is easy to process, and produces less processing waste. Making the side length of the filter screen 111 greater than the diameter of the axial ventilation opening 8211 enables all fresh air flows entering the axial ventilation opening 8211 to pass through the filter screen 111, resulting in a high filtration cleanliness level.

[0226] Even further, 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 member 11 away from the fresh air fan portion 6, and the fresh air inlet 801 communicates with the cavity V0121.

[0227] That is to say, the purification member 11 is arranged at a position in the fresh air cavity V012 close to the fresh air fan portion 6, and the part of the fresh air cavity V012 away from the fresh air fan portion 6 is the 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 portion 6 operates, the cavity V0121 is in a negative pressure state, enabling the air flow to automatically flow from the fresh air inlet 801 into the cavity V0121, reducing the air flow resistance.

[0228] The cavity V0121 is equivalent to the air inlet negative pressure cavity of the fresh air fan portion 6, and the setting of the air inlet negative pressure cavity has many advantages:

[0229] 1. Improve the air inlet efficiency. Specifically, by setting the negative pressure cavity, the buffer space on the air suction side of the fresh air fan portion 6 is increased, making it easier for the fresh air fan portion 6 to suck air, thereby increasing the air intake of the fresh air fan portion 6. Moreover, due to the existence of the negative pressure cavity, the fresh air is buffered and adjusted in the negative pressure cavity before entering the fresh air fan portion 6, reducing the fluctuations and turbulences of the fresh air flow, which is beneficial to improving the air inlet stability of the fresh air fan portion 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 portion 6 will rise.

[0230] 2. Optimize the air flow distribution. Specifically, through the buffering and guiding of the negative pressure cavity, it is beneficial to guide the air flow to be axially sucked into the fresh air fan portion 6.

[0231] 3. Reduce air flow impact and absorb noise.

[0232] In this way, while increasing the air intake of the fresh air module, it is beneficial to the overall air inlet reliability and stability.

[0233] In some embodiments, a positioning boss 8221 is formed on one side of the blower housing 822 facing the indoor heat exchanger 2. The base 3 has an end plate 31 at one end adjacent to the blower housing 822, and the end plate 31 is used to mount the indoor heat exchanger 2 and the heat exchange fan 41. A positioning recess 311 is formed on the end plate 31, and the positioning boss 8221 and the positioning recess 311 are inserted and mated with each other so that the blower housing 822 and the base 3 at least partially overlap in the lateral direction.

[0234] In this way, on the one hand, the positioning boss 8221 and the positioning recess 311 are inserted and mated with each other to form the positioning of the two-way ventilation assembly, and on the other hand, the overall lateral dimension can be reduced so that the wall-mounted air conditioner 10000 will not be too long.

[0235] In some embodiments, an installation opening 803 is further provided on the fresh air volute 8, and the purification member 11 is detachably assembled in the installation opening 803. This facilitates the disassembly of the purification member 11 when the purification member 11 is damaged or saturated, which is convenient for maintenance or replacement.

[0236] Specifically, as Figure 15 shown, the installation opening 803 is formed by enclosing between the blower housing 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 larger, which is convenient for installing 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 blower housing 822 and the second volute half 821, and the open half-ports are respectively formed on the blower housing 822 and the second volute half 821, which is convenient for processing or demolding, and the forming rejection rate is low.

[0237] Specifically, as Figure 3 shown, in the front-rear direction of the main body, the installation opening 803 is located on the front side of the main body 1000. When the purification member 11 is disassembled, it can be free from the interference of the pipes connected to the fresh air inlet 801 and the exhaust outlet 902, so that the disassembly is convenient for operation. Optionally, a switchable panel (not shown in the figure) is provided on the front side of the housing 1. When the panel is opened or rotated upward, the installation opening 803 can be exposed, which is convenient for the disassembly of the purification member 11.

[0238] It is not excluded that in some solutions, the installation opening 803 is provided at the bottom of the main body 1000.

[0239] In some embodiments, as Figure 6As shown, a purified air inlet 804 for connecting to the room is formed on the fresh air volute 8, and the integrated fan 60 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.

[0240] This arrangement can realize the circulation of indoor air when the indoor air is polluted, and purify it during the circulation. In this way, the indoor air can be purified without introducing outdoor fresh air, improving the cleanliness. Since no outdoor fresh air is introduced, the indoor air will not suddenly blow into the unheated cold or hot air from the outside during the indoor air purification, avoiding the discomfort caused by the sudden change of indoor temperature.

[0241] Specifically, Figure 6 As shown, the purification air inlet 804 is located at the bottom of the fresh air volute 8 and is set downward. It can be understood that the fresh air inlet 801 is located below the main body 1000, and the fresh air inlet 801 and the purification air inlet 804 are both located at the bottom of the fresh air volute 8 and are facing downward, which is convenient for processing and molding. And in use, one of the two is selected to open. At this time, the fresh air inlet 801 and the purification air inlet 804 are both placed at the bottom of the fresh air volute 8, which is convenient for centrally setting switches to select one of the air inlets to open, reducing the number of switches.

[0242] Furthermore, if Figure 6 As shown, the air inlet direction of the purification air inlet 804 is perpendicular to the length direction of the main body 1000. It can be understood that by making the air inlet direction of the purification air inlet 804 perpendicular to the length direction of the main body 1000, the air suction area of ​​the purification air inlet 804 is far away from the exhaust air inlet 901, avoiding the purification air inlet 804 and the exhaust air inlet 901 being too close to generate excessive air suction energy consumption. Moreover, the different directions of the purification air inlet 804 and the exhaust air inlet 901 help to expand the negative pressure area, help a large amount of indoor air flow into the negative pressure area, and ensure the exhaust and indoor fresh air volume.

[0243] In some embodiments, the first volute 81 is provided with a volute through hole 815, the integrated fan 60 is provided through the volute through hole 815, the outer diameter of the exhaust fan unit 7 is smaller than the diameter of the volute through hole 815, and the outer diameter of the fresh air fan unit 6 is larger than the diameter of the volute through hole 815. Figure 8 and Figure 11 The outer diameter of the exhaust fan unit 7 is D2, which is smaller than the diameter D0 of the volute through hole 815, and the outer diameter of the fresh air fan unit 6 is D1, satisfying D2<D0<D1. In this way, the exhaust fan unit 7 can pass through the volute through hole 815, while the fresh air fan unit 6 cannot pass through the volute through hole 815. Figure 8, when assembling the two-way ventilation component, the integrated fan 60 is first assembled with the second motor 5 to form a component, and then this component is assembled with the fresh air volute. The exhaust fan part 7 passes through the volute perforation 815 from right to left, the fresh air fan part 6 is located inside the fresh air volute 8, and the exhaust fan part extends leftward outside the fresh air volute 8. Then the exhaust volute 9 is assembled with the fresh air volute 8, and finally the second motor 5 is fixedly installed on the exhaust volute 9.

[0244] It should be noted that the outer diameter D1 of the fresh air fan part 6 refers to the maximum distance between two points on the fresh air fan part 6 along the radial direction of the integrated fan 60 passing through the axis of the integrated fan 60. The outer diameter D2 of the exhaust fan part 7 refers to the maximum distance between two points on the exhaust fan part 7 along the radial direction of the integrated fan 60 passing through the axis of the integrated fan 60. The diameter D0 of the volute perforation 815 refers to the maximum distance between two points on the hole wall of the volute perforation 815 along the radial direction of the volute perforation 815 passing through the axis of the volute perforation 815.

[0245] Refer to Figure 16 , 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 towards the heat exchange fan 41, and the volute perforation 815 is formed in the central partial area of the first volute end plate 811.

[0246] In some embodiments, refer to Figure 8 , the exhaust volute 9 and the fresh air volute 8 are connected, and the first volute end plate 811 is shared between them, and the fresh air duct V01 and the exhaust air duct V02 are separated by the first volute end plate 811. Such a setting enables there to be no need for an interval gap between the exhaust volute 9 and the fresh air volute 8, further reducing the axial dimension of the two-way ventilation component, decreasing the occupied space in the wall-mounted air conditioner 10000, and being beneficial to the overall thin and light design of the wall-mounted air conditioner 10000.

[0247] Optionally, the first volute end plate 811 is a single-layer plate, which makes the structure simple and is beneficial to reducing the overall axial dimension.

[0248] In some embodiments, as Figure 5 and Figure 8 shown, the exhaust volute 9 includes a wind guide ring 91. The wind guide ring 91 is in the shape of a circular tube, and the diameter of the wind guide ring 91 gradually decreases in the direction towards the heat exchange fan 41. The area surrounded by the wind guide ring 91 forms an 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 into the exhaust fan part 7, making the air intake smoother and more efficient, and improving the air intake volume of the exhaust fan part 7.

[0249] 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 unit 7 at the best angle, improving the working efficiency of the exhaust fan unit 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 unit 7 to operate more smoothly. It can reduce noise and vibration and extend the service life of the exhaust fan unit 7.

[0250] 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. The distance between the part of the blade side edge 721 close to the second motor 5 and the exhaust wheel disc 71 decreases, and all the exhaust blades 72 form a side edge depression 73 at the place where the distance of the blade side edge 721 decreases; the end of the air guide ring 91 is located in the side edge depression 73.

[0251] That is to say, the exhaust blades 72 of the exhaust fan unit 7 are concave blades, and both the air guide ring 91 and the concave blades are recessed towards the fresh air fan unit 6. The air guide ring 91 partially enters the side edge depression 723 formed by the concave blades. With such a setting, the air guide ring 91 and the exhaust fan unit 7 can have partial overlap in the axial direction, and it is not necessary to increase the axial dimension of the exhaust volute 9 on the premise of setting the air guide ring 91.

[0252] In some alternative embodiments, as Figure 6 shown, the wall-mounted air conditioner 10000 further includes: a first valve assembly 12 for opening or closing the fresh air inlet 801. In this way, the fresh air inlet 801 can be selectively opened and closed.

[0253] In some embodiments, the first valve assembly 12 includes: a fresh air valve, the fresh air valve is installed on the fresh air volute 8, and the fresh air valve is used for opening or closing the fresh air inlet 801; when the fresh air valve opens the fresh air inlet 801 and the integrated fan 60 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. The specific structure of the fresh air valve is not limited here.

[0254] In some embodiments, the first valve assembly 12 further includes: a fresh air valve motor, the fresh air valve motor is installed on the fresh air volute 8 and is used for driving the fresh air valve to open or close the fresh air inlet 801.

[0255] In some embodiments, the fresh air valve is used to switch between opening and closing the fresh air inlet 801 and the purification inlet 804. Specifically, the fresh air valve can selectively open one of the fresh air inlet 801 and the purification inlet 804, and close the other one of the fresh air inlet 801 and the purification inlet 804.

[0256] In some embodiments, such as Figure 6 shown, the wall-mounted air conditioner 10000 further includes: a second valve assembly 15 for opening or closing the exhaust air outlet 902. In this way, the exhaust air outlet 902 can be selectively opened and closed.

[0257] In some embodiments, the second valve assembly 15 includes: an exhaust valve, which is installed in the exhaust volute 9 and is used for opening or closing the exhaust air outlet 902; when the exhaust valve opens the exhaust air outlet 902 and the integrated fan 60 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 from the exhaust air outlet 902. The specific structure of the exhaust valve is not limited here.

[0258] In some embodiments, the second valve assembly 15 further includes: an exhaust valve motor, which is installed in the exhaust volute 9 and is used for driving the exhaust valve to open or close the exhaust air outlet 902.

[0259] In some embodiments, such as Figure 1 shown, an air outlet 105 is provided on the housing 1. The air outlet 105 of the housing corresponds to the fresh air outlet 802 of the fresh air volute 8, so that the fresh air discharged from the fresh air outlet 802 can be discharged from the air outlet 105 of the housing.

[0260] In some specific embodiments, the fresh air outlet 802 is located in the front of the main body 1000, and correspondingly, the air outlet 105 of the housing can be provided on the front side of the housing 1, so as to facilitate the output of fresh air from the front of the main body 1000. When the wall-mounted air conditioner 10000 is installed on the wall, especially at a high position on the wall, there are fewer obstacles in the front, and blowing air from the front can ensure a larger air supply area for fresh air.

[0261] In some other specific embodiments, the fresh air outlet 802 is located at the top of the main body 1000, and correspondingly, the air outlet 105 of the housing can be provided on the top wall of the housing 1, so that the fresh air is blown towards the roof, and the roof can be used 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.

[0262] Moreover, since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, the position of the heat exchange air inlet 101 on the housing 1 is relatively high. In this way, part of the fresh air blown out from the top of the fresh air outlet 802 can be inhaled again into the accommodation cavity V1 through the heat exchange air inlet 101 and flow through the indoor heat exchanger 2.

[0263] Such a setting is beneficial to the fresh air quickly reaching the room temperature and improving the comfort when the fresh air is blown in on the one hand, and on the other hand, it is beneficial to the fresh air being 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, and the uniformity of the fresh air distribution in the room is improved.

[0264] In some other specific 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. Correspondingly, the casing air outlet 105 can be arranged below the casing 1.

[0265] 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 casing 1 is relatively low, the fresh air outlet 802 blows fresh air from below, making the air outlet area of the casing air outlet 105 close to or even partially overlapping with the air outlet area of the heat exchange air outlet 102. This is beneficial to the mixing of fresh air and 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.

[0266] 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 relatively large, and improving the overall circulation efficiency of the indoor air.

[0267] Moreover, the fresh air outlet 802 is located below the main body 1000, close to the activity space of people, which is convenient for people to observe the fresh air outlet condition. This achieves the visual effect of fresh air outlet, which is beneficial to improving people's experience perception.

[0268] Specifically, 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 that the fresh air can reach the ground and also ensuring that the fresh air can reach a sufficient distance.

[0269] Optionally, as Figure 1 and Figure 3 shown, a wind deflector grille 16 is provided at the casing air outlet 105 of the casing 1 to adjust the air outlet direction of the fresh air.

[0270] In some embodiments, as Figure 1 shown, a casing air inlet 103 is provided at one end of the casing 1 where the second motor 5 is located, and the casing air inlet 103 is located at the top of the main body 1000. A first continuous ventilation duct V04 is formed between the casing air inlet 103 and the exhaust air inlet 901. The exhaust air fan part 7 rotates to drive the indoor air to enter the first continuous ventilation duct V04 from the casing air inlet 103, and makes the indoor air enter the exhaust air volute 9 through the exhaust air inlet 901.

[0271] That is to say, there is no need to connect a physical pipeline between the chassis air inlet 103 and the exhaust air inlet 901. Only relying on the wind pressure, the air flow is sucked in from the top. The chassis air inlet 103 is located at the top of the chassis 1, that is, in the area that the user cannot see. Hiding the chassis air inlet 103 can improve the appearance beauty.

[0272] In some other embodiments, a chassis air inlet 103 is provided at one end of the chassis 1 where the second motor 5 is located, and the chassis air inlet 103 is located on the side of the main body 1000. The exhaust fan part 7 rotates to drive the indoor air to enter the interior of the chassis 1 from the chassis air inlet 103, and the indoor air enters the exhaust volute 9 through the exhaust air inlet 901. That is to say, there is no need to connect a physical pipeline between the chassis air inlet 103 and the exhaust air inlet 901, and the chassis air inlet 103 is located on the side of the main body 1000 and can be directly opposite to the exhaust air inlet 901.

[0273] In this way, on the one hand, the air inlet path from the chassis air inlet 103 to the exhaust air inlet 901 becomes shorter, and the air inlet path from the chassis air inlet 103 to the exhaust air inlet 901 is generally arranged along the axial direction of the exhaust fan part 7. When the indoor air flows along this air inlet path to the exhaust fan part 7, the air flow does not need to change the flow direction multiple times. In this way, the air inlet resistance of the exhaust can be further reduced to ensure the exhaust air intake.

[0274] In some embodiments, the integrated fan 60 can be a plastic part, so that it is light in weight and low in cost. Of course, the solution of this application is not limited to this, and the integrated fan 60 can also be a resin part, a metal part, etc.

[0275] Similarly, the exhaust volute 9 can be a plastic part, so that it is light in weight and low in cost. Optionally, the exhaust volute 9 can be an injection molded part. Of course, the solution of this application is not limited to this, and the exhaust volute 9 can also be a metal part, etc.

[0276] The fresh air volute 8 can be a plastic part, so that it is light in weight and low in cost. Optionally, the fresh air volute 8 can be an injection molded part. Of course, the solution of this application is not limited to this, and the fresh air volute 8 can also be a metal part, etc.

[0277] In some embodiments, the accommodation cavity V1 in the main body 1000 is divided into a first chamber V11 and a second chamber V12, as Figure 2 shown by the dotted line frame. The indoor heat exchanger 2 is located in the first chamber V11, and at least part of the two-way ventilation component is arranged in the second chamber V12. The heat exchange air inlet 101 and the heat exchange air outlet 102 on the chassis 1 are arranged corresponding to the first chamber V11, and the chassis air inlet 103 and the chassis air outlet 105 on the chassis 1 are arranged corresponding to the second chamber V12.

[0278] With such a setting, the accommodation cavity V1 is partitioned into a first chamber V11 and a second chamber V12. The airflow inside the second chamber V12 will not be affected by the driving of the heat exchange fan 41. The exhaust air inlet 901 can directly intake air from the second chamber V12, and there is no need to connect a pipe between the casing air inlet 103 and the exhaust air inlet 901. This not only reduces the space occupied by the pipe body, but also allows the position of the casing air inlet 103 to be flexibly selected.

[0279] In the solution of the present application, a vertically arranged partition plate can be provided inside the casing 1 to separate the first chamber V11 and the second chamber V12, or the first chamber V11 and the second chamber V12 can be separated by the fresh air volute 8 or the base 3, or the cooperation of the two.

[0280] For example Figure 4 In some specific embodiments as shown, the indoor heat exchanger 2 and the heat exchange fan 41 are installed on the base 3. End plates 31 are provided at both lateral ends of the base 3. Both ends of the indoor heat exchanger 2 are installed on the two end plates 31, and both ends of the heat exchange fan 41 are installed on the two end plates 31.
