[0089] Some embodiments of the present invention provide a wall-mounted air conditioner 10000 .

[0090] Typically, the air conditioner is a split-type air conditioner, including an indoor unit and an outdoor unit. The indoor unit and the outdoor unit are connected by a pipeline to transmit refrigerant. The indoor unit includes an indoor heat exchanger 2 and a heat exchange fan 41.

[0091] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan and a throttling device. The compressor, outdoor heat exchanger, throttling device and indoor heat exchanger 2 connected in sequence form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger 2 respectively to realize the cooling mode or heating mode of the air conditioner.

[0092] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0093] The outdoor heat exchanger is configured to exchange heat between outdoor air and the refrigerant transported through the outdoor heat exchanger. For example, in the air conditioner's cooling mode, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to condense by dissipating heat to the outdoor air through the outdoor heat exchanger. In the air conditioner's heating mode, the outdoor heat exchanger operates as an evaporator, causing the decompressed refrigerant to absorb heat from the outdoor air through the outdoor heat exchanger and evaporate.

[0094] In some embodiments, the outdoor heat exchanger may include heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0095] The outdoor fan is configured to draw outside air into the outdoor unit and send the outside air after heat exchange with the outdoor heat exchanger to the outside. The outdoor fan provides power for the flow of the outdoor air.

[0096] A throttle element is connected between the outdoor heat exchanger and the indoor heat exchanger 2. It regulates the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger 2, thereby adjusting the refrigerant flow rate 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 throttle element can be a throttle tube, an electronic valve, or the like. If the throttle element is an electronic valve, the throttle opening is adjustable to adjust the flow rate and pressure of the refrigerant flowing through the throttle element.

[0097] In some solutions, the air conditioner may include a four-way valve connected to the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner performs cooling mode or heating mode.

[0098] The indoor heat exchanger 2 is configured to exchange heat between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2. In some embodiments, the indoor heat exchanger 2 may include heat exchange fins to increase the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0099] The heat exchange fan 41 is configured to draw indoor air into the indoor unit and deliver the indoor air after heat exchange with the indoor heat exchanger 2 to the room. The heat exchange fan 41 provides power for the flow of indoor air.

[0100] The air conditioner may include a control device, which is primarily used to control the operating frequency of the compressor and the opening of the throttle element. Some control devices can also control the speed of the outdoor fan and the speed of the heat exchange fan 41. The control device is connected to the compressor, the throttle element, the motor that drives the outdoor fan, and the common motor 42 that drives the heat exchange fan 41 via a data line to transmit communication information.

[0101] The control device includes a processor, which may include a central processing unit (CPU), a microprocessor (microprocessor), or an application specific integrated circuit (ASIC), and may be configured to perform corresponding operations described in the control device when the processor executes a program stored in a non-temporary computer-readable medium coupled to the control device.

[0102] Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disk, floppy disk, or tape), smart cards, or flash memory devices (e.g., erasable programmable read-only memory (EPROM), cards, sticks, or keyboard drives).

[0103] Currently, most wall-mounted air conditioners are limited in size and weight, typically only capable of cooling or heating the indoor air. If users leave the air conditioner on for extended periods and find the indoor air stale and stuffy, they might need to open windows for ventilation. This is not only cumbersome, but also causes the indoor cooling or heating to quickly escape through the windows while they're open, impacting comfort.

[0104] Some fresh air air conditioners in the related art draw in fresh air from the outside through a fresh air device and exhaust the indoor air through an exhaust device. However, the heat exchange fan, fresh air device, and exhaust device all require separate motors to drive them, resulting in high costs and bulky wall-mounted air conditioners.

[0105] In order to solve the above problems, some embodiments of the present invention provide a wall-mounted air conditioner 10000, which can reduce the overall size, reduce the number of motors and save costs by allowing the heat exchange fan, exhaust fan and fresh air fan to share the same motor.

[0106] For example, the wall-mounted air conditioner 10000 is an indoor unit. The wall-mounted air conditioner 10000 is usually installed on a wall, for example, can be installed in the upper area of ​​an indoor wall.

[0107] The following combination Figures 1-19 The wall-mounted air conditioner 10000 according to an embodiment of the present application is described in detail.

[0108] Reference Figure 1 and Figure 2As shown, a wall-mounted air conditioner 10000 according to an embodiment of the present application includes a main body 1000, which includes a housing 1. A housing 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 serves as a protective element and constitutes the overall external structure of the wall-mounted air conditioner 10000.

[0109] Typically, the housing 1 is an elongated shell with its length running horizontally, meaning it is mounted horizontally on a wall. In actual products, to drain condensed water, the housing 1 is mounted horizontally on a wall in some embodiments at a small angle to the horizontal plane.

[0110] Reference Figure 3 and Figure 4 The main body 1000 also includes an indoor heat exchanger 2, which is disposed within the housing chamber V1. As described above, the indoor heat exchanger 2 is a link in the refrigerant circuit. Refrigerant circulates within the indoor heat exchanger 2, cooling or heating the air flowing through the surface of the indoor heat exchanger 2. In a wall-mounted air conditioner 10000, the indoor heat exchanger 2 typically extends along the length of the housing 1.

[0111] For example, the indoor heat exchanger 2 is a two-fold or three-fold heat exchanger, and each fold of the indoor heat exchanger 2 is a plate-shaped structure extending along the length direction.

[0112] Reference Figure 3-Figure 5 The main body 1000 also includes a base 3, which is disposed within the accommodating cavity V1. The base 3 serves as a mounting support structure within the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. For example, a volute-tongue air duct V03 is formed on the base 3. After indoor air enters the housing 1, it is guided by the volute-tongue air duct V03, ensuring that the indoor air encounters minimal resistance as it flows through the indoor heat exchanger 2.

[0113] Reference Figure 4-Figure 5 The wall-mounted air conditioner 10000 further includes a heat exchange fan 41, which is disposed in the volute air duct V03. When the heat exchange fan 41 rotates, the air inside the air conditioner can exchange heat with the indoor space.

[0114] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which produces low noise and high airflow. The airflow velocity of the cross-flow fan is evenly distributed along the fan's axis, facilitating a greater air delivery distance and range. Furthermore, when a cross-flow fan is used and positioned along the length of the heat exchange fan 41, the driven airflow can flow through the entire indoor heat exchanger 2, ensuring balanced heat exchange efficiency across each position within the indoor heat exchanger 2.

[0115] By providing a heat exchange outlet 102 and a heat exchange inlet 101 in the housing 1, the heat exchange fan 41 can draw indoor air into the housing 1 through the heat exchange inlet 101 when in operation. After the indoor air exchanges heat with the indoor heat exchanger 2, the heat exchanged air is delivered to the room through the heat exchange outlet 102.

[0116] In this way, the indoor ambient temperature can be regulated. The indoor heat exchanger 2 can be used as an evaporator to enable the heat exchange outlet 102 to provide cooling airflow toward the indoor space, or the indoor heat exchanger 2 can be used as a condenser to enable the heat exchange outlet 102 to provide heating airflow toward the indoor space.

[0117] In some embodiments, in the height direction of the main body 1000 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102 , so that air can enter from the top and exit from the bottom.

[0118] For example, the height direction of the main body 1000 is the up-down direction.

[0119] It is understood that the main body 1000 is usually mounted on a wall. To avoid interfering with people's daily lives, the main body 1000 is usually hung at a higher position. By setting the main body 1000 to blow out the heated air from below, the blown heated air is less likely to be blocked by the roof or the ground. In this way, the heated air encounters less resistance and consumption during the blowing process, and the air supply range is wide, so that the heated air can flow to the entire indoor space as quickly as possible, thereby improving the heat exchange efficiency.

[0120] Reference 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 take in air from above, which can avoid taking in air from the heat exchange air outlet 102, and avoid the heat exchange air being blown out from the heat exchange air outlet 102 and being directly sucked into the heat exchange air inlet 101, thereby reducing the heat exchange air idling and not participating in the indoor heat exchange process.

[0121] In some embodiments, the heat exchange air inlet 101 is located at the top of the casing 1, that is, in an area that is invisible to the user. Hiding the heat exchange air inlet 101 can improve the appearance of the wall-mounted air conditioner 10000.

[0122] In some embodiments, the heat exchange air outlet 102 is located directly in front of the housing 1 , that is, the heat exchange air outlet 102 blows air toward the front side of the main body 1000 .

[0123] It can be understood that the side of the main body 1000 connected to the wall is usually called the back or rear side, and the side opposite to the rear side is called the front side. Therefore, when the heat exchange outlet 102 is located directly in front of the casing 1, the air outlet is away from the wall, the blowing resistance is small, and the air supply range is wide.

[0124] In some embodiments, the heat exchange air outlet 102 is located on the front side of the housing 1 and near the bottom. For example, the heat exchange air outlet 102 is located at the front lower corner of the housing 1. In this case, the heated air blown out of the heat exchange air outlet 102 flows forward and downward at the same time. In this way, after the heated air is delivered to a certain distance, it can sink and fall on people or objects on the ground, so that people or objects on the ground can be placed in a suitable indoor environment as soon as possible.

[0125] Reference Figure 4-Figure 6 The wall-mounted air conditioner 10000 further includes a common motor 42, which is disposed within the accommodating cavity V1 and located at one end of the heat exchange fan 41 in the longitudinal direction. This facilitates installation and maintenance of the common motor 42, and eliminates the need for the main body 1000 to be excessively tall or thick due to the placement of the common motor 42. The height of the main body 1000 corresponds to the vertical direction, and the thickness of the main body 1000 corresponds to the front-to-back direction.

[0126] In some embodiments, as Figure 8 、 Figure 16 As shown, the wall-mounted air conditioner 10000 may include a motor bracket, which may be fixed on the base 3 . The motor bracket is used to fix the common motor 42 , thereby allowing the common motor 42 to be securely mounted on the main body 1000 .

[0127] It is understood that the wall-mounted air conditioner 10000 is generally a long strip structure, and the length direction of the heat exchange fan 41 is the same as the length direction of the main body 1000. Figure 1-Figure 3 Left-right direction shown in .

[0128] Reference Figure 8 、 Figure 10-12 The wall-mounted air conditioner 10000 also includes a fresh air fan 6, which is a centrifugal fan with axial air intake and radial air discharge. The fresh air fan 6 is located at the end of the common motor 42 away from the heat exchange fan 41, that is, the common motor 42 is located in the space between the fresh air fan 6 and the heat exchange fan 41.

[0129] Reference Figure 7 、 Figures 9-11 、 Figure 13 The wall-mounted air conditioner 10000 further includes an exhaust fan 7, which is a centrifugal fan with axial air intake and radial air discharge.

[0130] Among them, the exhaust fan 7 is located between the common motor 42 and the heat exchange fan 41. When the common motor 42 is in working state, it drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate synchronously.

[0131] Centrifugal fans offer a compact structure, high air volume, and low noise. Fan noise decreases significantly as the speed decreases. Therefore, smaller centrifugal fans can be used for fresh air fan 6 and exhaust fan 7 to meet high air volume requirements. Centrifugal fans also produce low vibration noise and are less likely to resonate with indoor heat exchanger 2, thus reducing overall vibration and noise within wall-mounted air conditioner 10000.

[0132] Both fresh air fan 6 and exhaust fan 7 utilize centrifugal fans, allowing for optimally arranged wind directions. For example, fresh air fan 6 draws air axially and discharges air radially, while exhaust fan 7 draws air axially and discharges air radially. Fresh air fan 6 and exhaust fan 7 draw air from opposite ends of the fan, each driven to discharge air radially. This eliminates the need for axial overlap or intersection of the fresh and exhaust air paths. This helps minimize the need for avoidance angles in the fresh and exhaust air paths, reducing wind resistance and energy consumption, ensuring consistent airflow, and lowering noise.

[0133] In some embodiments, reference Figure 5-Figure 6 、 Figure 10-11 , the common motor 42 is located between the fresh air fan 6 and the exhaust fan 7. The exhaust fan 7 is closer to the heat exchange fan 41 than the fresh air fan 6. When the wall-mounted air conditioner 10000 is cooling or heating, the heat exchange fan 41 operates to drive the indoor air entering the casing 1 through the heat exchange air inlet 101 to flow through the indoor heat exchanger 2. The exhaust fan 7 is close to the heat exchange fan 41, and the air inlet end of the exhaust fan 7 is close to the air inlet end of the heat exchange fan 41. The exhaust fan 7 can draw air from the air inlet end of the heat exchange fan 41. In other words, when the exhaust fan 7 rotates, it draws the indoor air drawn into the casing 1 from the heat exchange air inlet 101 to the exhaust fan 7. This eliminates the need to open additional holes in the casing 1 to separately supply air to the exhaust fan 7. This reduces the number of openings in the casing 1, simplifies the processing and manufacturing process of the casing 1, and improves the aesthetics. In addition, the heat exchange air inlet 101 is generally set to be larger, so the amount of indoor air sucked into the casing 1 through the heat exchange air inlet 101 is larger, so that the air volume reaching the exhaust fan 7 is also larger, which speeds up the exhaust efficiency.

[0134] In some embodiments, the fresh air fan 6 is disposed on the side of the exhaust fan 7 away from the indoor heat exchanger 2. When condensed water is present on one side of the indoor heat exchanger 2, the condensed water is less likely to reach the fresh air fan 6, thereby reducing the risk of water accumulation and bacterial growth on the fresh air fan 6.

[0135] In some embodiments, the fresh air fan 6 and the exhaust fan 7 are both centrifugal fans, and the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are all driven by the same motor, which not only saves the number of motors, reduces the overall size and saves costs, but also keeps the three fans arranged in a stacked manner along the axial direction of the common motor 42.

[0136] In some embodiments, the centrifugal fan itself is relatively flat in the axial direction. The coaxial arrangement of the fresh air fan 6 and the exhaust fan 7 can reduce the overall axial dimension occupied by the main body 1000, thereby reducing the length of the main body 1000. Because the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 are all driven by the same motor, the three fans rotate synchronously and in unison.

[0137] The heat exchange fan 41, exhaust fan 7, common motor 42 and fresh air fan 6 are arranged in the length direction of the main body 1000, rather than in the thickness or height direction of the main body 1000, so that the main body 1000 of the wall-mounted air conditioner 10000 has a slender, slim and thin appearance.

[0138] In some embodiments, the common motor 42 is an outer rotor motor.

[0139] In other embodiments, the common motor 42 is an inner rotor motor.

[0140] Reference Figure 7-11 The wall-mounted air conditioner 10000 further includes a fresh air volute 8, which defines a fresh air duct V01. A fresh air fan 6 is mounted within the fresh air volute 8. The fresh air volute 8 defines a fresh air inlet 801 and a fresh air outlet. The fresh air fan 6 rotates to allow outdoor air to enter the fresh air volute 8 through the fresh air inlet 801 and to allow outdoor air entering the fresh air volute 8 to enter the room through the fresh air outlet.

[0141] In other words, fresh air fan 6 is disposed within fresh air duct V01. The rotation of fresh air fan 6 allows outdoor air to enter fresh air duct V01 through fresh air inlet 801, and allows the outdoor air entering fresh air duct V01 to enter the room through the fresh air outlet. Fresh air fan 6 is used to drive airflow from fresh air inlet 801 to the fresh air outlet and into the room. The operation of fresh air fan 6 provides the driving force for the flow of fresh air.

[0142] Therefore, by setting up the fresh air duct V01 in conjunction with the fresh air fan 6, when the indoor air is relatively dirty or the air quality is poor, the fresh air outside can be driven into the indoor environment through the fresh air fan 6 to improve the indoor airflow environment.

[0143] In some embodiments, the number of the fresh air outlet may be one.

[0144] In some embodiments, the number of fresh air outlets can be multiple, for example, two, three, four or more. By providing multiple fresh air outlets, the air volume can be increased.

[0145] In some embodiments, there are multiple fresh air outlets, and the multiple fresh air outlets are arranged in the same direction.

[0146] In some embodiments, there are multiple fresh air outlets, and the multiple fresh air outlets are arranged in different directions.

[0147] In some embodiments, the fresh air outlet includes a first fresh air outlet 802 and a second fresh air outlet 808, both of which are connected to the fresh air duct V01. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air duct V01 from the fresh air inlet 801, and allows outdoor air entering the fresh air duct V01 to enter the room through the first fresh air outlet 802 and the second fresh air outlet 808.

[0148] Reference Figure 12-16 The wall-mounted air conditioner 10000 further includes an exhaust volute 90, which is located between the fresh air volute 8 and the common motor 42. An exhaust duct V02 is formed in the exhaust volute 90. An exhaust fan 7 is mounted in the exhaust volute 90. An exhaust inlet 901 and an exhaust outlet 902 are formed in the exhaust volute 90. The rotation of the exhaust fan 7 allows indoor air to enter the exhaust volute 90 through the exhaust inlet 901 and allows the indoor air entering the exhaust volute 90 to be discharged to the outside through the exhaust outlet 902.

[0149] In other words, exhaust fan 7 is located within exhaust duct V02. The rotation of exhaust fan 7 allows indoor air to enter exhaust duct V02 through exhaust inlet 901, and also allows the indoor air entering exhaust duct V02 to be discharged outdoors through exhaust outlet 902. Exhaust fan 7 is used to drive airflow from exhaust inlet 901 to exhaust outlet 902. The operation of exhaust fan 7 provides the power to move the dirty air.

[0150] Therefore, by setting up the exhaust duct V02 and cooperating with the exhaust fan 7, when the indoor air is relatively polluted or the air quality is poor, the exhaust fan 7 can suck out the polluted air in the indoor space. In this way, when the indoor air volume is reduced, fresh air will be sucked in from the outside or from other rooms through doors and windows, thereby reducing the pollution level of the indoor air.

[0151] The fresh air fan 6 and the fresh air volute 8 constitute a fresh air device, and the exhaust fan 7 and the exhaust volute 90 constitute an exhaust device. The fresh air device and the exhaust device are arranged in the main body 1000. The fresh air device can provide fresh air for the room, and the exhaust device can exhaust the indoor air to the outside.

[0152] It should be noted that, in the wall-mounted air conditioner 10000, the operating modes of the fresh air device and the exhaust device can be set according to actual usage requirements.

[0153] In some embodiments, the fresh air device and the exhaust device together constitute a two-way ventilation component. The two-way ventilation component can run the fresh air mode and the exhaust mode at the same time, that is, the fresh air duct V01 and the exhaust duct V02 can be opened at the same time. While the indoor dirty air flow flows to the outdoor space, the outdoor fresh air can also enter the indoor space. Through the one-in and one-out airflow drive combination, it is beneficial to increase the improvement efficiency of the indoor space airflow, thereby meeting the user's needs in time when the user urgently needs to exhaust or update the indoor air.

[0154] Furthermore, since fresh air is replenished into the room while exhausting indoor air, sufficient indoor air is maintained, making it easier to draw in indoor air. For example, if there is a leak of irritating gases (such as those released by home improvement materials), coal gas, or other gases indoors, a two-way ventilation assembly can be configured to operate in both fresh air and exhaust modes simultaneously, achieving rapid ventilation. Furthermore, compared to conventional fresh air structures that simply introduce fresh air, the two-way ventilation assembly in some embodiments has a greater purification flow rate per unit time, higher ventilation efficiency, and better purification effects.

[0155] Furthermore, when ventilating, the ventilation is prevented from changing too quickly, which would cause a drastic change in indoor temperature, as would be the case with directly opening a window, thereby preventing discomfort to indoor occupants due to sudden temperature rises or drops. Furthermore, the main body 1000 is located at a higher position, so the ventilation position will not be too close to people, causing discomfort.

[0156] In some embodiments, the two-way ventilation component can use a valve to selectively operate in either fresh air mode or exhaust mode. Specifically, the two-way ventilation component can activate the fresh air mode while disabling the exhaust mode, allowing only the fresh air duct V01 to be ventilated while the exhaust duct V02 remains ventilated. Alternatively, the two-way ventilation component can activate the exhaust mode while disabling the fresh air mode, allowing only the fresh air duct V01 to be ventilated while the exhaust duct V02 remains ventilated.

[0157] It is understood that when wall-mounted air conditioner 10000 is in cooling mode, the two-way ventilation assembly draws fresh air from the outside into the room, and the cooling energy generated by wall-mounted air conditioner 10000 remains indoors, minimizing cooling loss. Cooling loss can be reduced by exhausting indoor air to the outside through exhaust duct V02 and setting the exhaust air volume to be smaller than the fresh air volume.

[0158] The two-way ventilation assembly is positioned at one end of the heat exchange fan 41 in the longitudinal direction. Compared to a main body without the two-way ventilation assembly, only the horizontal length is increased, and the height and thickness of the main body 1000 can remain substantially unchanged or vary slightly. This results in a thin and light appearance for the main body 1000. Hanging it on the wall does not obtrusively affect the interior layout, nor does it make it difficult to secure the wall-mounted air conditioner 10000 due to excessive weight, thus reducing the risk of it falling off the wall. The wall-mounted air conditioner 10000 remains thin and light overall, making it aesthetically pleasing when hung on the wall while maintaining a manageable weight.

[0159] According to the wall-mounted air conditioner 10000 of the embodiment of the present application, the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6 share the same motor, which can reduce the overall size, reduce the number of motors, and save costs. The architecture of the wall-mounted air conditioner 10000, from right to left, is as follows: the heat exchange fan 41, the exhaust fan 7, the common motor 42, and the fresh air fan 6, with the exhaust fan 7 located between the heat exchange fan 41 and the common motor 42. The location of the common motor 42 between the exhaust fan 7 and the fresh air fan 6 makes the common motor 42 closer to the exhaust fan 7, and the common motor 42 closer to the fresh air fan 6. This improves the dynamic balance performance of the overall architecture, increases overall integration, reduces the radial runout of the heat exchange fan 41, the exhaust fan 7, and the fresh air fan 6, and makes operation more stable and quiet.

[0160] Compared with the layout in which the common motor 42 is set in the order from right to left: the common motor 42, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6, in the present application, from right to left: the heat exchange fan 41, the exhaust fan 7, the common motor 42 and the fresh air fan 6, so that the cumulative tolerance is smaller. In this way, the gap between the exhaust fan 7 and the exhaust volute 90 can be made smaller, and the gap between the fresh air fan 6 and the fresh air volute 8 can be made smaller, thereby minimizing the length of the entire machine.

[0161] In addition, if the layout method of the common motor 42, heat exchange fan 41, exhaust fan 7 and fresh air fan 6 is adopted from right to left, each fan of the heat exchange fan 41, exhaust fan 7 and fresh air fan 6 needs to be separately injection molded during molding, and then the molded fan is embedded in the next fan mold for secondary injection molding, and so on. A total of three injection moldings are required to form the fan. This method requires three positioning and concentricity corrections, and there are multiple positioning errors, which increases the cumulative error and makes the manufacturing process difficult. That is, the more series connections are made, the greater the difficulty. However, the layout method of the present application of the heat exchange fan 41, exhaust fan 7, common motor 42 and fresh air fan 6 from right to left is adopted. Since the fresh air fan 6 is fixed separately from the common motor 42 and does not need to be injection molded synchronously with other fans, the difficulty of the production process will be reduced.

[0162] The heat exchange fan 41, exhaust fan 7, and fresh air fan 6 are driven by the same motor, and can start and stop at the same time, with the same speed. In the related art, the fresh air fan and the exhaust fan are driven by separate motors, which is costly. The present invention uses one motor to drive three fans, which saves two motors and greatly reduces costs.

[0163] In some embodiments of the present application, reference is made to Figure 4-Figure 6As shown, the common motor 42 includes a first output shaft 421. The exhaust fan 7 and the heat exchange fan 41 are both fixedly connected to the first output shaft 421. When the common motor 42 is in operation, the first output shaft 421 drives the exhaust fan 7 and the heat exchange fan 41 to rotate synchronously. The exhaust fan 7 and the first output shaft 421, as well as the heat exchange fan 41 and the first output shaft 421, can be non-circular or interference fits to prevent relative rotation between the exhaust fan 7 and the first output shaft 421, as well as between the heat exchange fan 41 and the first output shaft 421.

[0164] In some embodiments of the present application, reference is made to Figure 4-Figure 6 As shown, the common motor 42 includes a second output shaft 422, and the fresh air fan 6 is fixedly connected to the second output shaft 422. When the common motor 42 is in operation, the second output shaft 422 drives the fresh air fan 6 to rotate. The fresh air fan 6 and the second output shaft 422 can have a non-circular fit or an interference fit to prevent relative rotation between the fresh air fan 6 and the second output shaft 422.

[0165] Thus, a common motor 42 drives the three fans, namely the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6, to rotate, and the number of motors is small, thus saving costs.

[0166] In some embodiments not shown in the figures, the wall-mounted air conditioner 10000 further includes a drive shaft, and the common motor 42 includes a first output shaft 421 and a second output shaft 422. The exhaust fan 7 is fixedly connected to the first output shaft 421, and the heat exchange fan 41 is fixedly connected to the drive shaft. The drive shaft and the first output shaft 421 are connected via a coupling, and the fresh air fan 6 is fixedly connected to the second output shaft 422. In this way, the first output shaft 421 does not need to be made excessively long, and the common motor 42 has better dynamic balance. In this case, when the common motor 42 is in operation, the first output shaft 421 drives the exhaust fan 7 to rotate, and the first output shaft 421 drives the drive shaft to rotate synchronously. The drive shaft drives the heat exchange fan 41 to rotate, and the second output shaft 422 drives the fresh air fan 6 to rotate. The exhaust fan 7 and the first output shaft 421 may have a non-circular or interference fit to prevent relative rotation between them. The heat exchange fan 41 and the drive shaft may have a non-circular or interference fit to prevent relative rotation between them. The fresh air fan 6 and the second output shaft 422 may have a non-circular or interference fit to prevent relative rotation between them.

[0167] In some embodiments of the present application, reference is made to Figure 3-Figure 4 、 Figure 12-16 As shown, the exhaust volute 900 includes: an exhaust volute half 9, and the exhaust volute half 9 is located between the common motor 42 and the heat exchange fan 41.

[0168] In some embodiments of the present application, the exhaust volute 900 further includes a second exhaust volute half 91, which is located on a side of the exhaust volute half 9 away from the heat exchange fan 41, and is detachably connected to the exhaust volute half 9. For example, the second exhaust volute half 91 and the exhaust volute half 9 can be connected and fixed to the exhaust volute half 9 by fasteners or by a snap-fit ​​structure.

[0169] In some embodiments of the present application, the exhaust volute 900 further includes an exhaust volute portion 122, which is adapted to be detachably connected to at least one of the exhaust volute half 9 and the exhaust volute second half 91. The exhaust volute portion 122 forms an exhaust duct V02 within the exhaust volute half 9 and the exhaust volute second half 91. For example, the exhaust volute portion 122 may be detachably connected only to the exhaust volute half 9, only to the exhaust volute second half 91, or simultaneously to the exhaust volute half 9 and the exhaust volute second half 91.

[0170] In some embodiments of the present application, the exhaust volute half 9 and the exhaust volute portion 122 enclose an exhaust air inlet 901 , and the exhaust volute half 9 and the exhaust volute second half 91 enclose an exhaust air outlet 902 .

[0171] In some embodiments of the present application, reference is made to Figure 3-Figure 4 、 Figure 7-11 As shown, the fresh air volute 8 includes a first volute half 81 , which is located on a side of the common motor 42 away from the exhaust fan 7 .

[0172] In some embodiments of the present application, reference is made to Figure 3-Figure 4 、 Figure 7-11 As shown, the fresh air volute 8 further includes: a fresh air volute portion 121, which is detachably connected to the first volute half 81, and the fresh air volute portion 121 and the first volute half 81 form a part of the fresh air duct V01.

[0173] In some embodiments, reference Figure 3-Figure 4 、 Figure 7-Figure 16As shown, the fresh air volute portion 121 and the exhaust air volute portion 122 are separate components. When installing the two-way ventilation component on the main body 1000, the heat exchange fan 41, the exhaust fan 7, the common motor 42 and the fresh air fan 6 can be assembled into a motor-fan assembly first, and then the first volute half 81, the exhaust volute half 9 and the exhaust volute second half 91 can be installed on the base 3, and then the motor-fan assembly can be installed on the main body 1000, so that the fresh air fan 6 is located in the first volute half 81, and the exhaust fan 7 is located in the exhaust volute half 9 and the exhaust volute second half 91. Finally, the fresh air volute part 121 is connected and fixed to the first volute half 81 by fasteners, and the exhaust volute part 122 is connected and fixed to the exhaust volute half 9 and / or the exhaust volute second half 91 by fasteners, so that the fresh air volute part 121 is covered above the fresh air fan 6, and the exhaust volute part 122 is covered above the exhaust fan 7.

[0174] Optionally, the fastener may be a bolt, a screw, etc., and the fastener may firmly connect two parts.

[0175] Optionally, the fresh air volute portion 121 and the first volute half 81 can also be connected and fixed by a snap structure, and the exhaust volute portion 122 and the exhaust volute half 9 and / or the exhaust volute second half 91 can also be connected and fixed by a snap structure.

[0176] In some embodiments, as Figure 3 As shown, exhaust inlet 901 is partially formed on exhaust volute half 9, and the other portion is formed on exhaust volute portion 122. Exhaust inlet 901 is axially arranged along the length of heat exchange fan 41. In other words, exhaust inlet 901 directly faces the axial inlet end of exhaust fan 7, minimizing wind resistance to exhaust fan 7 entering through exhaust inlet 901 and ensuring sufficient exhaust airflow. If exhaust and air intake are more convenient, a smaller exhaust fan 7 can be selected, further reducing the size of exhaust volute 90.

[0177] The axial direction of the exhaust air inlet 901 is toward the indoor heat exchanger 2. In this way, the air inlet area of ​​the exhaust air inlet 901 is toward the indoor heat exchanger 2. The exhaust air inlet 901 is close to the heat exchange air inlet 101. The air intake volume at the heat exchange air inlet 101 is large. A part of the wind entering the casing 1 from the heat exchange air inlet 101 can enter the exhaust air duct V02 through the exhaust air inlet 901, so that the air volume at the exhaust air inlet 901 is sufficient.

[0178] The air inlet side of the exhaust fan 7 is on the side close to the indoor heat exchanger 2. The air inlet of the exhaust fan 7 can utilize the gap between the exhaust volute 90 and the indoor heat exchanger 2, thereby saving the space of the entire machine.

[0179] In some embodiments, combined Figure 2-Figure 4As shown, a first connecting air duct V04 is formed between the heat exchange air inlet 101 and the exhaust air inlet 901. The exhaust fan 7 rotates to drive the indoor air from the heat exchange air inlet 101 into the first connecting air duct V04, and allows the indoor air to enter the exhaust air duct V02 through the exhaust air inlet 901.

[0180] That is to say, there is no need for a physical pipe to connect the heat exchange air inlet 101 and the exhaust air inlet 901, and the air flow is sucked in from the top only by wind pressure.

[0181] In some embodiments of the present application, reference is made to Figure 3-Figure 4 、 Figure 7-11 As shown, the fresh air volute 8 further includes a second volute 82 , which is located on a side of the first volute half 81 away from the heat exchange fan 41 , and the second volute 82 is detachably connected to the first volute half 81 .

[0182] In some embodiments of the present application, the second volute 82 includes a second volute half 821, which is located on the side of the first volute half 81 away from the heat exchange fan 41, and the second volute half 821 is detachably connected to the first volute half 81. An axial vent 8211 is provided on the second volute half 821, and a volute cavity V011 is formed between the second volute half 821, the fresh air volute portion 121 and the first volute half 81, and the fresh air fan 6 is located in the volute cavity V011.

[0183] In some embodiments of the present application, the second volute 82 also includes a fan cover 822, which is located on the side of the second volute half 821 away from the heat exchange fan 41, and the fan cover 822 is detachably connected to the second volute half 821, and the cavity enclosed by the fan cover 822 and the second volute half 821 is the fresh air cavity V012.

[0184] In some embodiments of the present application, the fresh air inlet 801 is formed on the fan cover 822, the second volute half 821 and the first volute half 81 surround the first fresh air outlet 802, and the second volute half 821 and the fresh air volute part 121 surround the second fresh air outlet 808.

[0185] Figure 19The figure shows a schematic diagram of the fresh air fan 6 in the fresh air volute portion 121 and the first volute half 81. The first volute half 81 has a first enclosing plate 811 arranged on the radially outer side of the fresh air fan 6. The fresh air volute portion 121 has a second enclosing plate 1211 arranged on the radially outer side of the fresh air fan 6. The first enclosing plate 811 and the second enclosing plate 1211 are connected to form a fresh air volute curve. Since the fresh air fan 6 is coaxially arranged with the heat exchange fan 41, and the outer diameter of the fresh air fan 6 is larger than the outer diameter of the heat exchange fan 41, and And since the thickness of the main body 1000 is certain, the arrangement of the fresh air fan 6 in the fresh air volute part 121 and the first volute half 81 is skewed, and the fresh air fan 6 cannot be located at the center of the fresh air volute curve, which leads to a reduction in the amount of air thrown out from the first fresh air outlet 802. Therefore, by setting a second fresh air outlet 808 above the fresh air fan 6, the amount of air blown out from the fresh air volute is increased, which makes up for the defect of reduced air volume due to the limitation of the position of the fresh air fan 6.

[0186] When the fresh air fan 6 is coaxially arranged with the heat exchange fan 41, the axis of the fresh air fan 6 is fixed. Conventional volute curve designs prevent expansion, limiting the work done by the blades of the fresh air fan 6 and significantly reducing air volume. When two fresh air outlets are designed, the space required for the volute curve to expand is half that of a single outlet. The blades of the fresh air fan 6 can fully expand, blowing air out of both outlets, thereby increasing air volume.

[0187] That is to say, compared with the fresh air volute 8 that only has the first fresh air outlet 802, the fresh air volute 8 of the present application has both the first fresh air outlet 802 and the second fresh air outlet 808, so that the air output is larger.

[0188] By dividing the fresh air volute 8 into at least the first volute half 81, the second volute half 821, the fan cover 822, and the fresh air volute portion 121, and processing them separately, and dividing the exhaust volute 90 into at least the exhaust volute half 9, the exhaust volute second half 91, and the exhaust volute portion 122, and processing them separately, the difficulty of manufacturing and assembly can be reduced. Moreover, the quality control of such a complex housing can be facilitated after the separate manufacturing. The separate volutes are detachably connected to facilitate assembly, and also facilitate subsequent adjustment and maintenance.

[0189] It is understandable that the two parts can be detachably connected, and the connection and fixation can be achieved by fasteners or by a snap-fit ​​structure.

[0190] In some embodiments, the exhaust fan 7 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the exhaust fan 7 can also be a resin part, a metal part, etc.

[0191] In some embodiments, the fresh air fan 6 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the fresh air fan 6 can also be a resin part, a metal part, etc.

[0192] Similarly, the exhaust volute half 9 can be a plastic part, thereby being light in weight and low in cost. For example, the exhaust volute half 9 can be an injection molded part. In some embodiments, the exhaust volute half 9 can also be a resin part, a metal part, etc.

[0193] Similarly, the exhaust volute second half 91 can be a plastic part, thereby being light in weight and low in cost. For example, the exhaust volute second half 91 can be an injection molded part. In some embodiments, the exhaust volute second half 91 can also be a resin part, a metal part, etc.

[0194] Similarly, the exhaust volute portion 122 can be a plastic part, thereby being light in weight and low in cost. For example, the exhaust volute half 9 can be an injection molded part. In some embodiments, the exhaust volute portion 122 can also be a resin part, a metal part, etc.

[0195] The first volute half 81 can be a plastic part, thereby being light in weight and low in cost. For example, the first volute half 81 can be an injection molded part. In some embodiments, the first volute half 81 can also be a resin part, a metal part, etc.

[0196] The fresh air volute 121 can be a plastic part, thereby being light in weight and low in cost. For example, the fresh air volute 121 can be an injection molded part. In some embodiments, the fresh air volute 121 can also be a resin part, a metal part, etc.

[0197] The second volute 82 can be a plastic part, thereby being light in weight and low in cost. For example, the second volute 82 can be an injection molded part. In some embodiments, the second volute 82 can also be a resin part, a metal part, etc.

[0198] In some embodiments of the present application, reference is made to Figure 2-Figure 5 、 Figure 7-11 The wall-mounted air conditioner 10000 further includes a purification component 11, which is arranged in the fresh air duct V01 and is used to purify the fresh air blown into the room to improve the cleanliness of the indoor air.

[0199] For example, the purification element 11 is installed in the fresh air cavity V012 and is located at the axial air inlet end of the fresh air fan 6. The purification element 11 is connected to the second volute 82, which facilitates the assembly of the purification element 11 and prevents interference with the fresh air fan 6. The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air cavity V012 from the fresh air inlet 801. The outdoor air entering the fresh air cavity V012 is then blown through the purification element 11, enters the volute cavity V011, and enters the room through the fresh air outlet.

[0200] In this way, the fresh air flow can be blown almost vertically through the purification element 11, and the fresh air intake consumption can be further reduced, thereby increasing the fresh air volume. Moreover, when the indoor heat exchanger 2 is in the cooling state, causing condensation in the fresh air, the condensation can be retained on the purification element 11 when the air flows through the purification element 11, further avoiding the situation where water is blown away when the fresh air device is discharged.

[0201] In some embodiments, the fresh air outlet includes a first fresh air outlet 802 and a second fresh air outlet 808, both of which are connected to the fresh air duct V01. In this way, the outdoor air entering the volute cavity V011 enters the room through the first fresh air outlet 802 and the second fresh air outlet 808.

[0202] In some embodiments of the present application, Figure 11 As shown, the purification element 11 includes a filter (not shown in the figure), which is covered on the axial vent 8211. The filter covers the entire air inlet end of the fresh air fan 6. The filter covers a large area, has a large filtration area, and has a good filtration effect. The setting of the filter helps to ensure sufficient contact area with the flowing air, and is light in weight and has low wind noise. For example, the filter is a Hepa mesh, so it has strong adsorption capacity and is effective in filtering dust in the air.

[0203] In some embodiments of the present application, the filter is in the shape of a plate, so that the filter is thin as a whole and does not occupy an excessively thick size when placed in a two-way ventilation component.

[0204] In some embodiments of the present application, the filter is square, which facilitates the positioning and installation of the filter.

[0205] In some embodiments of the present application, the filter screen is a square screen, with a side length greater than the diameter of the axial vent 8211. This square screen facilitates positioning during installation, resists shaking once secured, and is easy to process, minimizing processing waste. By making the side length of the filter screen greater than the diameter of the axial vent 8211, all fresh air entering the axial vent 8211 can flow through the filter screen, resulting in high filtration cleanliness.

[0206] In some embodiments of the present application, reference is made to Figure 10 A portion of the fresh air cavity V012 constitutes an empty cavity V0121 . The cavity V0121 is located on a side of the purification element 11 away from the fresh air fan 6 . The fresh air inlet 801 is connected to the cavity V0121 .

[0207] For example, a purification component 11 is arranged in the fresh air cavity V012 near the fresh air fan 6, and the part of the fresh air cavity V012 away from the fresh air fan 6 is a cavity V0121, that is, the cavity V0121 is between the oncoming wind of the purification component 11 and the inner surface of the fan cover 822. In this way, when the fresh air fan 6 is running, the cavity V0121 is in a negative pressure state, so that the airflow can automatically flow into the cavity V0121 from the fresh air inlet 801, thereby reducing the air flow resistance.

[0208] Cavity V0121 is equivalent to the air inlet negative pressure chamber of the fresh air fan 6. The setting of the air inlet negative pressure chamber has many advantages:

[0209] 1. Improved air intake efficiency. For example, by providing a negative pressure chamber, the buffer space on the intake side of the fresh air fan 6 is increased, making it easier for the fresh air fan 6 to draw air, thereby increasing the air intake volume of the fresh air fan 6. Furthermore, the presence of the negative pressure chamber buffers and adjusts the fresh air in the negative pressure chamber before entering the fresh air fan 6, reducing fluctuations and turbulence in the fresh air flow and improving the air intake stability of the fresh air fan 6. Without cavity V0121 and the lack of buffer space, flow resistance increases, and the operating power consumption of the fresh air fan 6 will also increase.

[0210] 2. Optimizing airflow distribution: For example, the buffering and guiding of the negative pressure chamber can help guide the airflow axially into the fresh air fan 6.

[0211] 3. Reduce airflow impact and absorb noise.

[0212] In this way, while increasing the air intake volume of the fresh air device, it is also beneficial to improve the overall air intake reliability and stability.

[0213] In some embodiments of the present application, Figure 10-11 As shown, the fan cover 822 is also provided with an installation port 803, and the purification element 11 can be detachably assembled in the fresh air cavity V012 through the installation port 803. This makes it convenient to disassemble the purification element 11 when it is damaged or saturated, and to facilitate maintenance or replacement.

[0214] In some embodiments of the present application, Figure 2-Figure 5 、 Figure 11 As shown, in the front-to-back direction of the main body 1000, the mounting opening 803 is located on the front side of the main body 1000. When the purification element 11 is removed, it can be free from interference with the pipes connected to the fresh air inlet 801 and the exhaust air outlet 902, thereby facilitating removal. For example, the front side of the housing 1 is provided with an openable panel 15. When the panel 15 is opened or rotated upward, the mounting opening 803 is exposed, facilitating removal of the purification element 11.

[0215] It is also possible that in some solutions, the installation port 803 is set at the bottom of the main body 1000.

[0216] In some embodiments of the present application, Figure 8 、 Figure 10 As shown, the second volute 82 is formed with a purified air inlet 804 for communicating with the indoor air. The rotation of the fresh air fan 6 allows indoor air to enter the fresh air chamber V012 from the purified air inlet 804 to be purified by the purification element 11. The indoor air entering the fresh air chamber V012 is blown through the purification element 11, then enters the volute chamber V011 and enters the indoor air through the fresh air outlet. 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 indoor air through the fresh air outlet.

[0217] This setup allows for the indoor air to circulate and purify when it becomes polluted. This purifies the indoor air, improving cleanliness, without the need for fresh air. Because no fresh air is introduced, the indoor air purification process prevents sudden influx of unheated cold or hot air from outside, preventing discomfort caused by sudden changes in indoor temperature.

[0218] In some embodiments, the fresh air outlet includes a first fresh air outlet 802 and a second fresh air outlet 808, both of which are connected to the fresh air duct V01. In this way, the indoor air entering the volute cavity V011 enters the room through the first fresh air outlet 802 and the second fresh air outlet 808.

[0219] In some embodiments of the present application, the purification air inlet 804 can be connected to the heat exchange air inlet 101, and no pipe is required to connect the purification air inlet 804 and the heat exchange air inlet 101, which reduces the number of parts, reduces the occupied volume, and facilitates layout.

[0220] In some embodiments of the present application, Figure 8 As shown, the purified air inlet 804 is located at the bottom of the second volute 82 and is set downward. It can be understood that the fresh air inlet 801 is located below the main body 1000. The fresh air inlet 801 and the purified air inlet 804 are both located at the bottom of the fresh air volute and extend downward, which facilitates processing and molding. Moreover, during use, one of the two can be opened. In this case, the fresh air inlet 801 and the purified air inlet 804 are both placed at the bottom of the fresh air volute 8, which makes it convenient to centrally set switches to select one of the air inlets to open, reducing the number of switches.

[0221] In some embodiments, combined Figure 4 、 Figure 8As shown, the air inlet direction of the purified air inlet 804 is perpendicular to the length of the heat exchange fan 41. It will be appreciated that by aligning the air inlet direction of the purified air inlet 804 with the length of the heat exchange fan 41, the suction area of ​​the purified air inlet 804 is further away from the exhaust air inlet 901, thus avoiding excessive suction energy consumption caused by the purified air inlet 804 being too close to the exhaust air inlet 901. Furthermore, the different directions of the purified air inlet 804 and the exhaust air inlet 901 help expand the negative pressure area, allowing a larger amount of indoor air to flow into the negative pressure area, thereby ensuring the exhaust and indoor fresh air volume.

[0222] In some embodiments of the present application, the fresh air inlet 801 is located below the main body 1000 in the height direction of the main body 1000. It is understood that the fresh air inlet 801 must be connected to a pipe to introduce outdoor air, which is referred to herein as a fresh air introduction pipe. The fresh air introduction pipe can be a component of the wall-mounted air conditioner 10000, or it can be a fresh air introduction pipe that the user configures after purchasing the wall-mounted air conditioner 10000.

[0223] The fresh air inlet 801 is set below the main body 1000, and the fresh air introduction pipe can be connected to the fresh air inlet 801 from below. The connection generally extends in the up and down direction, rather than extending in the front and back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0224] The part used to install the fresh air fan 6 in the fresh air volute structure formed by the fresh air volute part 121 and the first volute half 81 is circular, and the axis of the fresh air fan 6 extends along the length direction of the heat exchange fan 41, so that the circle has free space on the front and rear sides of the bottom. This space can be used to set the fresh air inlet 801 to connect the fresh air introduction pipe, so that the connection between the fresh air introduction pipe and the fresh air inlet 801 can be placed in the free space without occupying additional space, so that the height size of the main body 1000 can be controlled.

[0225] In some embodiments, exhaust vent 902 is located below main body 1000 in the height direction of main body 1000. Similarly, exhaust vent 902 needs to be connected to a duct to guide indoor air to the outside. This duct is referred to herein as an exhaust duct. The exhaust duct can be a component of wall-mounted air conditioner 10000 or can be configured by the user after purchasing wall-mounted air conditioner 10000.

[0226] The exhaust outlet 902 is set below the main body 1000, and the exhaust outlet pipe can be connected to the exhaust outlet 902 from below. The connection generally extends in the up and down direction, rather than extending in the front and back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0227] The portion of the exhaust volute structure formed by the exhaust volute portion 122, the exhaust volute half 9, and the exhaust volute second half 91 for mounting the exhaust fan 7 is circular. The axis of the exhaust fan 7 extends along the length of the heat exchange fan 41, so that there is free space at the front and rear sides of the bottom of the circle. Furthermore, based on the characteristics of the exhaust fan 7, which takes in air axially and discharges air radially, the diffuser sections of the exhaust volute half 9 and the exhaust volute second half 91 can be arranged generally in the vertical direction and can be placed in the aforementioned free space at the front or rear sides. An exhaust outlet 902 is provided here to connect to the exhaust duct, so that the connection between the exhaust duct and the exhaust outlet 902 can be placed in this free space without occupying additional space, thereby controlling the height of the main body 1000.

[0228] In some embodiments, the wall-mounted air conditioner 10000 may include: a fresh air introduction pipe connected to the fresh air inlet 801, an exhaust air outlet pipe connected to the exhaust air outlet 902, such as Figure 1-Figure 2 As shown, a duct avoidance opening 104 is provided on the side wall of the housing 1. The fresh air intake duct connects to the fresh air inlet 801 from the bottom of the main body 1000, bends and extends horizontally, then extends from the duct avoidance opening 104 on the side wall of the housing 1 and then extends outdoors. The exhaust air outlet duct connects to the exhaust air outlet 902 from the bottom of the main body 1000, bends and extends horizontally, then extends from the duct avoidance opening 104 on the side wall of the housing 1 and then extends outdoors.

[0229] The fresh air inlet pipe and the exhaust air outlet pipe are two independent pipes, which help to separate the fresh air airflow path and the exhaust airflow path from each other, without any intersection, and reduce the risk of air leakage caused by cross-flow.

[0230] It is understandable that a refrigerant pipe and a drain pipe are usually provided 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.

[0231] A pipe avoidance opening 104 is provided on the side wall of the housing 1. The fresh air intake pipe and the exhaust air outlet pipe are then positioned horizontally and then led outward, facilitating the juxtaposition of at least one of the fresh air intake pipe and the exhaust air outlet pipe with the drain pipe and the refrigerant pipe. This juxtaposed multi-pipe arrangement is then wrapped with an external bundle of pipes or a bundle of bands, resulting in the multiple pipes appearing as a single pipe. This reduces the number of connected pipes required after the wall-mounted air conditioner 10000 is installed, resulting in a simpler appearance. This not only facilitates assembly but also prevents the risk of multiple pipes colliding.

[0232] In some embodiments of the present application, the first fresh air outlet 802 is located below the main body 1000 to guide the fresh air to flow forward and downward into the room. Thus, the air blown out from the first fresh air outlet 802 can be blown directly to the user.

[0233] In some embodiments of the present application, the first fresh air outlet 802 can discharge air into the room through the heat exchange outlet 102. This eliminates the need to create new housing outlets, simplifying the manufacturing process of the housing 1. Furthermore, the outlet area of ​​the first fresh air outlet 802 overlaps with the outlet area of ​​the heat exchange outlet 102, which facilitates mixing of the fresh air with the heat-exchanged indoor air. This improves the uniformity of the fresh air mixed with the indoor air, and allows the fresh air to absorb the cooling or heating of the heat-exchanged indoor air, bringing the fresh air temperature closer to the indoor temperature and improving ventilation comfort.

[0234] In some embodiments of the present application, the housing 1 is provided with a housing air outlet, which is separated from the heat exchange air outlet 102, and the first fresh air outlet 802 can discharge air into the room through the housing air outlet. The housing air outlet can be correspondingly provided below the housing 1.

[0235] Since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air outlet 102 is relatively low on the casing 1, the first fresh air outlet 802 blows out fresh air from below, so that the air outlet area of ​​the casing air outlet is close to or even partially overlaps with the air outlet area of ​​the heat exchange air outlet 102, which is conducive 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 after mixing in the indoor air. On the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, so that the temperature of the fresh air tends to the indoor temperature, thereby improving the blowing comfort.

[0236] The air outlet direction of the first fresh air outlet 802 is opposite to the air inlet direction of the heat exchange inlet 101. The fresh air blown out from the first fresh air outlet 802 will not be sucked into the heat exchange inlet 101, reducing the proportion of fresh air intake at the heat exchange inlet 101, making the total air outlet of the wall-mounted air conditioner 10000 larger, and improving the overall circulation efficiency of the indoor air.

[0237] The first fresh air outlet 802 is located below the main body 1000, close to the people's activity space, making it convenient for people to observe the fresh air outlet. This achieves a visual effect of fresh air outlet, which is conducive to improving people's experience.

[0238] When the first 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 be delivered to the ground and to a sufficiently long distance.

[0239] In some embodiments of the present application, an air guide grille is provided at the air outlet of the casing 1 to adjust the outlet direction of fresh air.

[0240] In some embodiments of the present application, Figures 1-4As shown, the second fresh air outlet 808 is located at the top of the main body 1000 to guide the fresh air upward into the room. When the wall-mounted air conditioner 10000 is in cooling mode, the air blown out from the second fresh air outlet 808 can settle from top to bottom, giving the user a top-down shower experience, making the user feel cooler and quickly lowering the indoor temperature.

[0241] In some embodiments of the present application, Figure 7-11 、 Figure 17 As shown, the fresh air fan 6 includes a fresh air disc 61 and fresh air blades 62. The fresh air blades 62 are located at the outer edge of the fresh air disc 61 and extend axially along the fresh air disc 61. The total axial thickness of the fresh air disc 61 and the fresh air blades 62 is h1. Here, the fresh air fan 6 can have a single fresh air disc 61 or at least two fresh air discs spaced apart along the axial direction. h1 is the maximum axial dimension of the fresh air fan 6.

[0242] like Figure 12-16 、 Figure 18 As shown, exhaust fan 7 includes an exhaust disc 71 and exhaust blades 72. Exhaust blades 72 are located at the outer edge of exhaust disc 71 and extend axially along exhaust disc 71. The total axial thickness of exhaust disc 71 and exhaust blades 72 is h2. Exhaust fan 7 can include one exhaust disc 71 or at least two exhaust discs 71 spaced apart in the axial direction. h2 represents the maximum axial dimension of exhaust fan 7.

[0243] Here, h2 < h1. This arrangement ensures that the fresh air volume is greater than the exhaust air volume while also increasing the axial thickness of the main body of the fresh air fan 7, thereby increasing structural strength and being able to withstand greater torque. Since the exhaust fan 7 requires less air volume, the smaller axial thickness of the main body can appropriately reduce the exhaust air volume and the axial dimensions of the two-way ventilation assembly.

[0244] In some embodiments of the present application, the fresh air fan 6 is a single-suction centrifugal fan with single-side suction, and the fresh air blades 62 extend along the axis of the fresh air wheel 61 in a direction away from the exhaust fan 7. As a result, when the fresh air fan 6 rotates, the fresh air blades 62 can reduce the air volume in the exhaust duct V02 from being snatched away.

[0245] In some embodiments of the present application, the exhaust fan 7 is a single-suction centrifugal fan with single-side suction, and the exhaust blades 72 extend along the axial direction of the exhaust disc 71 in a direction away from the fresh air fan 6. As a result, when the exhaust fan 7 rotates, the exhaust blades 72 can reduce the air volume in the fresh air duct V01 from being snatched away by the air.

[0246] In some embodiments of the present application, Figure 5-Figure 6As shown, the outer diameter of the fresh air fan 6 is larger than the outer diameter of the heat exchange fan 41, so that the fresh air volume is not too small. For example, in one embodiment, the outer diameter of the fresh air fan 6 is 137 mm, and the outer diameter of the heat exchange fan 41 is 94 mm.

[0247] In some embodiments of the present application, Figure 5-Figure 6 As shown, the outer diameter of the exhaust fan 7 is larger than the outer diameter of the heat exchange fan 41, thereby preventing the exhaust volume from being too small. For example, in one embodiment, the outer diameter of the exhaust fan 7 is equal to the outer diameter of the fresh air fan 6, and the outer diameters of the fresh air fan 6 and the exhaust fan 7 are both 137 mm, while the outer diameter of the heat exchange fan 41 is 94 mm.

[0248] In some embodiments, the exhaust outlet 902 is positioned downward, while the first fresh air outlet 802 is positioned forward. This not only allows the exhaust outlet 902 and the first fresh air outlet 802 to be directly aligned, but also facilitates connection to the exhaust outlet pipe by positioning the exhaust outlet 902 downward, allowing the exhaust outlet pipe to be positioned against a wall. The forward orientation of the first fresh air outlet 802 allows fresh air to be delivered forward, expanding the fresh air delivery range.

[0249] For example, the exhaust vent 902 is located on the rear side of the exhaust volute half 9, with the air outlet direction of the exhaust vent 902 downward. This not only prevents the exhaust duct from excessively lengthening the wall-mounted air conditioner 10000 when connected to the exhaust vent 902, but also allows the exhaust vent 902 to be located on the wall-facing side of the exhaust volute half 9, making it easier to create a shape that is wider at the back and narrower at the front.

[0250] When the main body 1000 is designed to be wide at the back and narrow at the front, with the wider back portion mounted against the wall, people viewing the wall-mounted air conditioner 10000 will see the narrower front portion, creating the impression that the wall-mounted air conditioner 10000 is thinner and lighter. This can reduce the perceived heaviness of the wall-mounted air conditioner 10000, thereby alleviating the feeling of oppression that may arise from hanging the wall-mounted air conditioner 10000 on the wall.

[0251] In some embodiments, the first fresh air outlet 802 is arranged to be downwardly discharged and tilted forward, which is conducive to allowing the wall-mounted air conditioner 10000 to discharge fresh air forward, ensuring that the fresh air can be delivered to the ground and to a sufficiently long distance.

[0252] For example, the first fresh air outlet 802 is located in front of the exhaust air outlet 902, so that the first fresh air outlet 802 and the exhaust air outlet 902 are staggered at a greater distance, which is more conducive to reducing mutual interference and facilitating takeover.

[0253] In some embodiments, reference Figure 2-Figure 4As shown, the wall-mounted air conditioner 10000 also includes an end plate 31, which is located at the end of the indoor heat exchanger 2 away from the exhaust fan 7, and the end plate 31 is connected to the indoor heat exchanger 2. The end plate 31 is used to install the indoor heat exchanger 2 on the base 3.

[0254] The wall-mounted air conditioner 10000 further includes a heat exchanger outlet pipe, which is connected to one end of the indoor heat exchanger 2 facing the exhaust fan 7.

[0255] The common motor 42 and the heat exchanger outlet pipe at least partially overlap in the length direction of the main body 1000 , thereby reducing the total length of the common motor 42 and the heat exchanger outlet pipe in the length direction of the main body 1000 .

[0256] In some embodiments of the present application, the outer diameter of the fresh air fan 6 is D1, and in the front-to-back direction of the main body 1000, the thickness dimension of the main body 1000 is T, D1:T≥1:1.7, D1:T≤1:1.3.

[0257] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness of the main body 1000 is greater than or equal to 1:1.7, that is, D1:T ≥ 1:1.7. When D1:T < 1:1.7, the outer diameter of the fresh air fan 6 is too small, resulting in a small amount of fresh air, and the effect of introducing fresh air into the room is poor. By setting D1:T ≥ 1:1.7, the outer diameter of the fresh air fan 6 is not too small, the fresh air volume is not too small, and the effect of introducing fresh air into the room is better.

[0258] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness of the main body 1000 is less than or equal to 1:1.3, that is, D1:T≤1:1.3. When D1:T>1:1.3, the outer diameter of the fresh air fan 6 is too large, which will occupy the space of the logarithmic spiral of the fresh air volute, resulting in the logarithmic spiral of the fresh air volute being incomplete or unable to be designed according to the maximum fresh air volume, resulting in too small fresh air volume and poor effect of introducing fresh air into the room. In the front-to-back direction of the main body 1000, the outer diameter of the fresh air fan 6 plus the reasonable limit size of the logarithmic spiral of the fresh air volute is equal to the thickness of the main body 1000. By setting D1:T≤1:1.3, the outer diameter of the fresh air fan 6 will not be too large, will not occupy the space of the logarithmic spiral of the fresh air volute too much, the logarithmic spiral of the fresh air volute is complete, and can be designed according to the maximum fresh air volume, thereby ensuring that the fresh air volume is not too small and the effect of introducing fresh air into the room is better.

[0259] For example, D1:T can be 1:1.3, 1:1.4, 1:1.5, 1:1.6, 1:1.7, etc., and can also be other values ​​between 1:1.7 and 1:1.3, which are not listed here one by one.

[0260] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness of the main body 1000 is 1:1.5, i.e., D1:T = 1:1.5. The outer diameter of the fresh air fan 6 is not too small, and the fresh air volume is not too small, effectively introducing fresh air into the room. The outer diameter of the fresh air fan 6 is not too large, and does not occupy the space of the logarithmic spiral of the fresh air volute. The logarithmic spiral of the fresh air volute is complete and can be designed according to the maximum fresh air volume, thereby ensuring that the fresh air volume is not too small and effectively introducing fresh air into the room.

[0261] In some embodiments of the present application, Figure 1-Figure 2 As shown, wall-mounted air conditioner 10000 further includes a panel 15, one end of which is pivotally connected to housing 1. For example, the upper end of panel 15 is pivotally connected to housing 1. Panel 15 is rotatable relative to housing 1. When panel 15 is rotated to an open position, purification element 11 is exposed, allowing the user to remove the filter within purification element 11. When panel 15 is rotated to a closed position, purification element 11 is obscured. In this case, panel 15 serves as an exterior component, giving wall-mounted air conditioner 10000 a cleaner appearance.

[0262] In some embodiments of the present application, Figure 1-Figure 2 As shown, the wall-mounted air conditioner 10000 further includes a windshield 16, the left and right ends of which are pivotally connected to the housing 1. The windshield 16 is rotatable relative to the housing 1. When the windshield 16 is rotated to the open position, the heat exchange air outlet 102 is exposed, facilitating air discharge from the heat exchange air outlet 102. When the windshield 16 is rotated to the closed position, the heat exchange air outlet 102 is blocked, preventing debris, flying insects, etc. from entering the wall-mounted air conditioner 10000 through the heat exchange air outlet 102 when the wall-mounted air conditioner 10000 is not in operation.
