[0002] This application claims priority to the patent application filed on March 17, 2025, with application number 202510314703.X, entitled "Wall-mounted Air Conditioner", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air conditioning technology, and more specifically, to a wall-mounted air conditioner. Background Technology

[0004] With the advancement of technology and the improvement of people's living standards, air conditioners have gradually entered people's lives and become an indispensable item in people's work and life.

[0005] An air conditioner consists of an indoor unit and an outdoor unit, which are installed indoors and outdoors respectively, connected by corresponding pipes and wires. Typically, to improve indoor air quality, air conditioners also include a fresh air intake system for ventilation. However, in some technologies, users cannot directly perceive the fresh air, resulting in a poor user experience. Summary of the Invention

[0006] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, this application proposes a wall-mounted air conditioner that allows users to directly experience fresh air.

[0007] The wall-mounted air conditioner according to an embodiment of this application includes a main body, the main body including a casing, an accommodating cavity formed inside the casing, and a heat exchange air inlet and a heat exchange air outlet formed on the casing. The casing can protect the components inside the accommodating cavity and constitutes the overall external structure of the wall-mounted air conditioner.

[0008] The main body also includes an indoor heat exchanger, which is disposed within the accommodating cavity. The indoor heat exchanger is a link in the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger to cool or heat the air flowing through its surface.

[0009] The main body also includes a heat exchange fan, which is configured to draw indoor air into the main body from the heat exchange inlet and send the indoor air after heat exchange with the indoor heat exchanger to the room through the heat exchange outlet. The heat exchange fan provides power for the flow of indoor air.

[0010] The main body also includes a first motor, which is disposed in the accommodating cavity. The first motor is used to drive the heat exchange fan to rotate so that the air inside the air conditioner exchanges heat with the indoor heat exchanger.

[0011] The main body also includes a panel, which is mounted on the front side of the casing. The panel is the main exterior surface of the wall-mounted air conditioner and can shield the casing and components inside the housing.

[0012] The wall-mounted air conditioner also includes a second motor, which is located at one end of the length direction of the main body, and the second motor is an external rotor motor.

[0013] The second motor includes a stator and a rotor. The rotor is arranged radially around the outside of the stator. Choosing an external rotor motor for the second motor is advantageous not only because of its simple structure, but also because the rotor is arranged radially around the outside of the stator, allowing for a larger rotor diameter and thus greater torque. This makes it suitable for low-speed, high-torque, and direct-drive applications. In other words, when the second motor outputs power, a speed reducer is not needed for torque amplification, saving space occupied by a speed reducer.

[0014] The second motor also includes a motor housing, which supports and protects the main body of the second motor. The motor housing is fixedly connected to the rotor, and the motor housing and rotor can rotate synchronously. This allows the rotor to be mounted through the motor housing, facilitating connection to external structures.

[0015] The second motor also includes an output shaft, which is fixedly connected to the motor housing.

[0016] The wall-mounted air conditioner also includes a fresh air fan, which is a diagonal-flow fan connected to the output shaft of the second motor. When the output shaft rotates, it drives the fresh air fan to rotate synchronously.

[0017] The wall-mounted air conditioner also includes a fresh air housing, within which a fresh air duct is formed. A fresh air fan is installed inside the fresh air housing, and a fresh air inlet and a fresh air outlet are formed on the fresh air housing. Both the fresh air inlet and the fresh air outlet are connected to the fresh air duct. Outdoor air enters the fresh air duct through the fresh air inlet and is blown into the indoor space through the fresh air outlet.

[0018] The rotation of the fresh air fan allows outdoor air to enter the fresh air housing through the fresh air inlet, and allows outdoor air entering the fresh air housing to enter the room through the fresh air outlet. The rotation of the fresh air fan provides driving force for the airflow.

[0019] The panel is equipped with an air outlet, and the fresh air outlet is connected to the panel air outlet. Outdoor air inside the fresh air housing can be blown forward through the fresh air outlet and the panel air outlet, so that the outdoor air entering the fresh air housing can be exhausted from the front of the main body. In this way, the fresh air blown forward from the panel air outlet can directly blow on the user, or give the user a top-down shower breeze experience. The user can intuitively feel the fresh air, resulting in a better user experience.

[0020] According to the wall-mounted air conditioner of the present application embodiment, by connecting the fresh air outlet with the panel air outlet, air can be vented forward from the panel, allowing users to intuitively feel the fresh air, which is beneficial to improving the user experience.

[0021] In this application, the fresh air fan adopts an oblique flow fan, and the exhaust air undergoes both centrifugal and axial motion. That is, the movement of the air discharged from the fresh air outlet into the room combines both axial and centrifugal motion. Among them, the axial motion of the air is conducive to sending the air further, while the centrifugal motion of the air is conducive to the air spreading around the panel outlet after being discharged, thereby expanding the air supply area.

[0022] According to some embodiments of this application, the fresh air fan includes a fresh air hub, which is connected to the output shaft. When the output shaft rotates, it drives the fresh air hub to rotate, thereby driving the entire fresh air fan to rotate.

[0023] The fresh air fan also includes a fan outer cylinder, which is arranged radially around the outside of the fresh air hub. A first airflow channel is formed between the fan outer cylinder and the fresh air hub. One end of the first airflow channel is a first airflow inlet, and the other end is a first airflow outlet. The first airflow outlet is connected to the panel air outlet. Outdoor air entering the fresh air duct from the fresh air inlet can flow into the first airflow channel from the first airflow inlet, then flow from the first airflow outlet to the fresh air outlet, and then to the panel air outlet, flowing into the indoor space through the panel air outlet.

[0024] The fresh air fan also includes fresh air blades located within the first airflow channel, connecting the fresh air hub and the fan outer cylinder. When the fresh air fan rotates, the fresh air blades propel the airflow, accelerating it and increasing the volume of air passing through them, thus enhancing the amount of fresh air supplied to the room by the fresh air device.

[0025] According to some embodiments of this application, the wall-mounted air conditioner further includes an air outlet guide, which is disposed in the accommodating cavity and located between the fresh air fan and the panel air outlet. The air outlet guide is provided with a second airflow channel, which communicates with the first airflow channel to guide the air in the fresh air housing to the panel air outlet.

[0026] In the airflow path, the second airflow channel is located between the first airflow outlet and the panel air outlet. Outdoor air entering the fresh air duct from the fresh air inlet can flow into the first airflow channel from the first airflow inlet, then into the second airflow channel from the first airflow outlet, and then flow to the panel air outlet, and then into the indoor space through the panel air outlet.

[0027] The air outlet deflector can rectify the airflow leaving the fresh air fan, making the airflow smoother, reducing airflow turbulence and eddies, improving the outlet pressure and efficiency of the fresh air fan, and also helping to reduce noise.

[0028] According to some embodiments of this application, the air outlet guide includes: an inner guide cylinder, an outer guide cylinder, and guide vanes. In the radial direction of the air outlet guide, the outer guide cylinder is disposed around the outside of the inner guide cylinder, forming a second airflow channel between the outer guide cylinder and the inner guide cylinder. The guide vanes are located within the second airflow channel and connect the inner guide cylinder and the outer guide cylinder. The guide vanes can divide the second airflow channel into multiple smaller channels, resulting in multiple streams of airflow being blown out, thereby improving the user's perceived comfort when fresh air is blown out. This avoids the discomfort caused to the user when a single stream of air is blown out directly without being divided into multiple streams.

[0029] The front end of the second airflow channel faces the air outlet of the panel, and the rear end of the second airflow channel faces the fresh air fan. When the fresh air fan rotates, outdoor air enters the fresh air housing from the fresh air inlet, passes through the first airflow channel and the fresh air outlet in sequence, reaches the second airflow channel, and is then blown forward through the air outlet of the panel.

[0030] According to some embodiments of this application, the inner circumferential surface of the outer guide cylinder and the outer circumferential surface of the inner guide cylinder both extend along the axial direction of the second motor to axially guide the airflow within the second airflow channel. This causes the airflow to be blown out along the axial direction of the second motor, i.e., forward in a direction perpendicular to the panel. The blown airflow is more concentrated and less prone to dispersion, which helps to improve the user's perception of fresh air flow.

[0031] According to some embodiments of this application, the fresh air blades are spiral blades. Thus, when the fresh air fan rotates, the fresh air blades can push the airflow, increasing the air speed and thus increasing air volume. Furthermore, the spiral blades have good wind pressure capability.

[0032] According to some embodiments of this application, the stator portion of the second motor is connected to the air outlet guide. The stator portion is fixed relative to the air outlet guide.

[0033] According to some embodiments of this application, the wall-mounted air conditioner further includes a motor bracket, which is located radially inside the inner guide cylinder and connected to the air outlet guide. The motor bracket is used to mount a second motor.

[0034] The stator is mounted on the motor bracket, and at least a portion of the output shaft, the rotor, the stator, and the motor housing are located between the motor bracket and the fresh air hub. This allows for full utilization of the space between the motor bracket and the fresh air hub, which helps to reduce the axial dimension of the fresh air system.

[0035] According to some embodiments of this application, the fresh air hub is open at one end facing the air outlet of the panel, and the air outlet guide further includes a reinforcing ring connected to the inner guide cylinder. At least a portion of the stator, the rotor, and the motor housing is located within the reinforcing ring. Thus, the second motor can occupy the space within the reinforcing ring, reducing the axial dimension of the fresh air device and making the wall-mounted air conditioner more compact in the front-to-back direction.

[0036] According to some embodiments of this application, the reinforcing ring is located within the fresh air hub. This can further reduce the axial dimension of the fresh air device.

[0037] According to some other embodiments of this application, the reinforcing ring is located outside the fresh air hub, and the end of the reinforcing ring is disposed opposite to the end of the fresh air hub. The outer peripheral surface of the reinforcing ring is a guide surface, and the outer peripheral surface of the hub expansion portion and the guide surface form an almost continuous and smooth guide structure. When the airflow flows from the first airflow channel to the second airflow channel, the airflow can flow sequentially over the outer peripheral surface of the hub expansion portion and the guide surface, thereby preventing abrupt changes in the airflow path.

[0038] According to some embodiments of this application, in the fresh air fan, the fresh air hub and the fresh air blades are integrally injection molded parts, while the fan outer cylinder is a separate part, and the fan outer cylinder is fixedly connected to the fresh air blades. This simplifies the processing and manufacturing difficulty of the fresh air fan.

[0039] According to some embodiments of this application, the inner wall of the fan outer cylinder is provided with a locking hole, and the blade edge of the fresh air blade is provided with a locking block, which is inserted into the locking hole. The fresh air blade is locked and fixed to the fan outer cylinder, which is convenient and quick to operate and helps to save the processing and manufacturing time of the fresh air fan.

[0040] According to some embodiments of this application, the fresh air fan includes a first baffle ring. The first baffle ring is arranged radially around and connected to the outer side of the fan outer cylinder. A first baffle groove is formed between the first baffle ring and the fan outer cylinder, and the opening of the first baffle groove faces the direction of the first airflow inlet. When airflow passes over the outer side of the fan outer cylinder, the first baffle ring can block the airflow, thereby reducing airflow noise. The airflow can briefly linger in the first baffle groove, further achieving a noise reduction effect. When the airflow attempts to flow towards the periphery of the fresh air fan, the airflow is blocked in the first baffle groove, increasing flow resistance and thus reducing the possibility of leakage.

[0041] According to some embodiments of this application, the fresh air housing includes a second air baffle ring disposed on the inner wall of the fresh air duct and surrounding the outer side of the fan outer cylinder. At least a portion of the second air baffle ring is located within the first air baffle groove. Thus, a near-sealed structure is formed between the second air baffle ring and the first air baffle ring. When airflow passes over the outer side of the fan outer cylinder, the second air baffle ring and the first air baffle ring can perform multi-stage obstruction of the airflow, further increasing the flow resistance and thereby further achieving a noise reduction effect.

[0042] According to some embodiments of this application, the flow area of ​​the first airflow channel decreases in the direction from the first airflow inlet to the first airflow outlet. Therefore, the first airflow channel has a significant converging effect on the airflow, making it less likely for the airflow to disperse. This results in a higher wind speed at the first airflow outlet than at the first airflow inlet. When the airflow is blown out from the fresh air outlet, the wind speed is higher, which helps to enhance the user's perception of fresh air and improve the user experience.

[0043] According to some embodiments of this application, the wall-mounted air conditioner further includes a purification component installed within the fresh air duct. The purification component purifies the fresh air blown into the room, improving the cleanliness of the indoor air. The purification component is connected to the fresh air housing and is located at the axial air inlet end of the fresh air fan. Rotation of the fresh air fan allows outdoor air to enter the fresh air housing from the fresh air inlet, and also allows the outdoor air entering the fresh air housing to pass through the purification component before entering the room from the fresh air outlet and the panel outlet, thereby improving the cleanliness of the indoor air.

[0044] According to some embodiments of this application, the purification component is vertically arranged and located behind the fresh air fan. This allows the fresh airflow to pass almost vertically over the purification component, further reducing fresh air intake consumption and increasing the fresh air volume. Furthermore, when the indoor heat exchanger is in cooling mode, causing condensation in the fresh air, the condensate can remain on the purification component as the air flows through it, further preventing water from being blown out of the fresh air unit.

[0045] According to some embodiments of this application, the fresh air housing is provided with a first mounting port, and the purification component is detachably assembled into the fresh air housing through the first mounting port. This facilitates the disassembly of the purification component when it is damaged or saturated, making maintenance or replacement convenient.

[0046] According to some embodiments of this application, the bottom of the housing is provided with a second mounting port facing the first mounting port, and the purification component is detachably assembled into the housing through the second mounting port. This allows the purification component to be installed and removed directly from the bottom of the housing without opening the panel, improving the convenience of replacing or repairing the purification component.

[0047] According to some embodiments of this application, the fresh air housing includes a first housing portion, the front of the first housing portion is open, and the bottom of the first housing portion is provided with the fresh air inlet.

[0048] The fresh air housing also includes a second housing portion connected to the front of the first housing portion. The fresh air fan is located inside the second housing portion. The front of the second housing portion is open to form the fresh air outlet and is positioned directly opposite the panel outlet.

[0049] By setting the fresh air housing into multiple shell sections, the processing and manufacturing of the fresh air housing can be facilitated, as well as the installation and disassembly of the internal components of the fresh air housing.

[0079] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0080] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0081] Some embodiments of the present invention provide a wall-mounted air conditioner 10000.

[0082] Typically, air conditioners are split-type air conditioners, which include an indoor unit and an outdoor unit. The indoor and outdoor units are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0083] 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 are connected in sequence to 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, respectively, to achieve the air conditioner's cooling mode or heating mode.

[0084] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0085] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0086] In some embodiments, the outdoor heat exchanger may include heat exchange fins to increase the contact area between outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0087] The outdoor fan is configured to draw in outside air into the outdoor unit and expel the outdoor air, which has been heated by the outdoor heat exchanger, to the outside. The outdoor fan provides power for the flow of outdoor air.

[0088] A throttling device connects the outdoor and indoor heat exchangers. It regulates the refrigerant pressure flowing through both devices, thereby controlling the refrigerant flow rate between them. The flow rate and pressure of the refrigerant between the outdoor and indoor heat exchangers affect their heat exchange performance. The throttling device can be a throttling tube, an electronic valve, etc. When the throttling device is an electronic valve, its opening is adjustable to regulate the refrigerant flow rate and pressure.

[0089] In some designs, the air conditioner may include a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform a cooling mode or a heating mode.

[0090] An indoor heat exchanger is configured to exchange heat between indoor air and a refrigerant transported within the indoor heat exchanger. In some embodiments, the indoor heat exchanger may include heat exchange fins to increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0091] The heat exchange fan is configured to draw indoor air into the indoor unit and deliver the indoor air, after heat exchange with the indoor heat exchanger, into the room, providing power for the flow of indoor air.

[0092] An air conditioner may include a control unit, which is mainly used to control the operating frequency of the compressor and the opening degree of the throttling device. Some control units can also control the speed of the outdoor fan and the heat exchange fan. The control unit is connected to the compressor, the throttling device, the motor driving the outdoor fan, and the motor driving the heat exchange fan via data cables to transmit communication information.

[0093] 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.

[0094] Non-transitory computer-readable storage media may include magnetic storage devices (e.g., hard disks, floppy disks, or magnetic tapes), smart cards, or flash memory devices (e.g., erasable programmable read-only memory, cards, sticks, or keyboard drives).

[0095] Currently, most wall-mounted air conditioners are limited by size and weight, and their functions are relatively limited, usually only able to cool or heat indoor air. If users feel that the indoor air is stale and stuffy after running the air conditioner for a long time, they need to open the windows for ventilation. This is not only inconvenient, but also causes the cool or warm air to escape quickly through the windows, affecting people's comfort.

[0096] Some air-conditioning systems using fresh air intake technology draw in fresh air from outdoors. However, users cannot directly perceive the fresh air, resulting in a poor user experience.

[0097] To address the aforementioned issues, some embodiments of the present invention provide a wall-mounted air conditioner 10000, which allows users to directly experience fresh air and enhances the user experience.

[0098] For example, the wall-mounted air conditioner 10000 is an indoor unit. The wall-mounted air conditioner 10000 is typically installed on a wall, for example, in the upper area of ​​an interior wall.

[0099] The following is combined Figures 1-21 Detailed description of the wall-mounted air conditioner 10000 according to an embodiment of this application.

[0100] Reference Figures 1-3 As shown, the wall-mounted air conditioner 10000 according to an embodiment of this application includes a main body 1000, the main body 1000 includes a casing 1, the casing 1 has an internal cavity V1, and the casing 1 has a heat exchange air inlet 101 and a heat exchange air outlet 102. The casing 1 can protect the components inside the cavity V1 and constitute the overall external structure of the wall-mounted air conditioner 10000.

[0101] Typically, the housing 1 is a long, rectangular shell, with its length positioned horizontally, meaning it is mounted on the wall laterally. In actual products, to drain condensate, in some embodiments the housing 1 is mounted horizontally on the wall at a small angle to the horizontal plane.

[0102] Reference Figures 4-6 The main body 1000 also includes an indoor heat exchanger 2, which is disposed within the accommodating cavity V1. As described above, the indoor heat exchanger 2 is a loop in the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger 2 to cool or heat the air flowing from the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is typically arranged to extend along the length of the casing 1.

[0103] 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.

[0104] The main body 1000 also includes a base, which is disposed within the accommodating cavity V1, and a volute-shaped air duct is formed on the base. The base is an internal mounting support structure of the main body 1000. The indoor heat exchanger 2 can be installed on the base. After the indoor air enters the casing 1, the flow direction is guided by the volute-shaped air duct to ensure that the resistance encountered by the indoor air when flowing through the indoor heat exchanger 2 is small.

[0105] Reference Figures 5-6 The main body 1000 also includes a heat exchange fan 41, which is disposed within a volute duct. The heat exchange fan 41 is configured to draw indoor air into the main body 1000 from the heat exchange inlet 101, and to deliver the indoor air, after heat exchange with the indoor heat exchanger 2, to the room via the heat exchange outlet 102, specifically through the volute duct and the heat exchange outlet 102. The heat exchange fan 41 provides power for the airflow within the room.

[0106] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which has low noise and large air volume, and the air velocity of the cross-flow fan is more uniformly distributed along the axial direction of the cross-flow fan, which is beneficial to increasing the air delivery distance and air delivery range. Moreover, when a cross-flow fan is used and the cross-flow fan is arranged along the length direction of the heat exchange fan 41, it is beneficial for the driven airflow to flow through the entire indoor heat exchanger 2, ensuring the balance of heat exchange efficiency of each part of the indoor heat exchanger 2.

[0107] The main body 1000 also includes a first motor, which is located in the accommodating cavity V1. The first motor is used to drive the heat exchange fan 41 to rotate so that the air can exchange heat with the indoor heat exchanger 2 inside the air conditioner.

[0108] By providing a heat exchange outlet 102 and a heat exchange inlet 101 in the casing 1, the heat exchange fan 41 can draw indoor air into the casing 1 through the heat exchange inlet 101 when it is running. After the indoor air exchanges heat with the indoor heat exchanger 2, the heat-exchanged air is sent back into the room through the heat exchange outlet 102.

[0109] Therefore, the indoor ambient temperature can be regulated. The indoor heat exchanger 2 can be used as an evaporator to provide cooling airflow to the indoor space through the heat exchange outlet 102, or the indoor heat exchanger 2 can be used as a condenser to provide heating airflow to the indoor space through the heat exchange outlet 102.

[0110] In some embodiments, the heat exchange air inlet 101 is located above the heat exchange air outlet 102 in the height direction of the main body 1000, so that air can be drawn in from the top and discharged from the bottom.

[0111] For example, the height direction of the main body 1000 is the vertical direction.

[0112] Understandably, the main unit 1000 is usually installed on the wall, and to avoid interfering with people's daily lives, it is typically hung at a high position. By setting the main unit 1000 to blow out heat exchange air from below, the blown heat exchange air is less likely to be blocked by the roof or ground. This results in less resistance and energy loss during the air blowing process, a wider air delivery range, and allows the heat exchange air to flow throughout the entire indoor space as quickly as possible, thus improving heat exchange efficiency.

[0113] Reference Figure 1 and Figure 4 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 prevent the heat exchange air from being blown out of the heat exchange air outlet 102 and directly sucked into the heat exchange air inlet 101, thus reducing the process of heat exchange air idling without participating in the indoor heat exchange.

[0114] In some embodiments, such as Figure 1As shown, the heat exchange air inlet 101 is located at the top of the casing 1, that is, in an area that the user cannot see. Hiding the heat exchange air inlet 101 can improve the appearance of the wall-mounted air conditioner 10000.

[0115] In some embodiments not shown in the figure, the heat exchange outlet 102 is located directly in front of the housing 1, that is, the heat exchange outlet 102 blows air towards the front of the main body 1000.

[0116] It is understandable that the side of the main body 1000 that is connected to the wall is usually called the back or rear side, while 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 air resistance is small, and the air delivery range is wide.

[0117] In some embodiments, the heat exchange outlet 102 is located on the front side of the housing 1 and near the bottom, for example, as Figure 4 As shown, the heat exchange air outlet 102 is located at the lower front corner of the casing 1. In this case, the heat exchange air blown out of the heat exchange air outlet 102 flows forward and downward at the same time, so that after being delivered to a certain distance, the heat exchange air can sink and fall onto people or objects on the ground, so that people or objects on the ground can be in a suitable indoor environment as soon as possible.

[0118] In some embodiments, 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 is understood that the heat exchange fan 41 is a power drive component that drives the indoor air to exchange heat with the indoor heat exchanger 2 by rotation, and is also a power drive component for air supply.

[0119] By placing the heat exchange fan 41 on the side of the indoor heat exchanger 2 away from the heat exchange inlet 101, the aerodynamic force generated when the heat exchange fan 41 rotates can be evenly distributed. Part of it is distributed to the air inlet side, so that the air drawn in can overcome the wind resistance generated by the indoor heat exchanger 2 when it flows into the volute air duct. The other part is distributed to the air outlet side, so that the air after heat exchange can be transported a longer distance when it is blown out from the heat exchange outlet 102.

[0120] In some embodiments, the first motor is located at one end of the heat exchange fan 41 along its length, such as the right end. This facilitates the installation and maintenance of the first motor, and the main body 1000 does not need to become excessively tall or thick due to the placement of the first motor. Here, the height direction of the main body 1000 is consistent with the vertical direction, and the thickness direction of the main body 1000 is consistent with the front-to-back direction.

[0121] It is understandable that wall-mounted air conditioners 10000 generally have a long, narrow structure, and the length of the heat exchange fan 41 is the same as the length of the main body 1000. Figure 1-Figure 2 , Figures 5-6 The left and right directions are shown.

[0122] The main body 1000 also includes a panel 12, which is installed on the front side of the housing 1. The panel 12 is the main exterior surface of the wall-mounted air conditioner 10000 and can cover the housing 1 and the components inside the accommodating cavity V1.

[0123] The wall-mounted air conditioner 10000 also includes a second motor 5, which is located at one end of the length of the main body 1000, in conjunction with... Figures 5-6 , Figure 9 , Figure 11 , Figures 18-21 The second motor 5 is located inside the accommodating cavity V1, at the left end of the length direction of the main body 1000. In this way, the first motor and the second motor 5 are located at opposite ends of the length direction of the heat exchange fan 41. On the one hand, the two motors are separated and far apart, resulting in less electromagnetic interference between them. On the other hand, the two motors are arranged at opposite ends of the length direction of the heat exchange fan 41, 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 have a slender shape, making it thin and light.

[0124] Reference Figure 9 , Figure 11 , Figures 18-21 As shown, the second motor 5 is an external rotor motor.

[0125] The second motor 5 includes a stator 51 and a rotor 52, with the rotor 52 arranged radially around the outside of the stator 51.

[0126] The stator section 51 and the rotor section 52 constitute the main body of the second motor 5. The stator section 51 has wound coils, which generate an alternating magnetic field when alternating current is applied, and the rotor section 52 is induced in the alternating magnetic field and rotates.

[0127] For example, the rotor section 52 can be a magnetic ring or a magnetic tile. For instance, if the rotor section 52 is a magnetic ring, leakage flux loss can be reduced, magnetic flux enhanced, and the power output efficiency of the second motor 5 improved. Furthermore, using a magnetic ring results in a more uniform magnetic field distribution, better anti-interference performance, and higher mechanical precision.

[0128] The second motor 5 is an external rotor motor. Not only is the external rotor motor simple in structure, but since the rotor part 52 is arranged radially around the outside of the stator part 51, the diameter of the rotor part 52 is large, which can obtain a large torque. It can be used in scenarios such as low speed and high torque, direct drive, etc. That is, when the second motor 5 outputs power outward, there is no need to set a reducer to reduce speed and increase torque, saving the space occupied by the reducer.

[0129] In addition, the rotor section 52 is located radially outside the stator section 51, with a larger heat dissipation area and better heat dissipation performance, which is beneficial to the stable operation of the second motor 5. Moreover, with this arrangement, the diameter of the second motor 5 can be controlled to be smaller, without encroaching on the airflow channel space.

[0130] Reference Figures 18-21 As shown, the second motor 5 also includes a motor housing 53, which supports and protects the main body of the second motor 5. The motor housing 53 is fixedly connected to the rotor portion 52, and the motor housing 53 and the rotor portion 52 can rotate synchronously. This allows the rotor portion 52 to be mounted through the motor housing 53, facilitating connection to external structures.

[0131] The second motor 5 also includes an output shaft 54, which is fixedly connected to the motor housing 53.

[0132] In the front-rear direction of the wall-mounted air conditioner 10000, one end of the output shaft 54 ​​extends rearward along the axial direction of the motor housing 53.

[0133] Reference Figures 9-16 As shown, the wall-mounted air conditioner 10000 also includes a fresh air fan 6, which is a diagonal flow fan. The fresh air fan 6 is connected to the output shaft 54 ​​of the second motor 5. When the output shaft 54 ​​rotates, it can drive the fresh air fan 6 to rotate synchronously.

[0134] In a mixed-flow fan, the airflow direction is at a certain angle (not 0 degrees) to the impeller axis. Air enters from the inlet along the axial direction, but the exhaust direction is along the diagonal direction of the axial and perpendicular axes. This gives the mixed-flow fan airflow and pressure characteristics between those of an axial fan and a centrifugal fan, providing both high airflow and a certain level of pressure capability. Mixed-flow fans operate with lower noise, offering better noise reduction compared to axial fans. Utilizing optimized blade design and fluid dynamics principles, mixed-flow fans improve ventilation efficiency and reduce energy consumption. Furthermore, their compact design, small size, and light weight facilitate installation and maintenance.

[0135] When the diagonal flow fan rotates, the airflow is mixed radially and laterally by the work done by the diagonal flow fan, which reduces airflow separation and turbulence, thereby reducing aerodynamic noise.

[0136] Reference Figures 5-11 As shown, the wall-mounted air conditioner 10000 also includes a fresh air housing 8, within which a fresh air duct V01 is formed. A fresh air fan 6 is installed inside the fresh air housing 8. A fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air housing 8. Both the fresh air inlet 801 and the fresh air outlet 802 are connected to the fresh air duct V01. Outdoor air enters the fresh air duct V01 through the fresh air inlet 801 and is blown into the indoor space through the fresh air outlet 802.

[0137] The rotation of the fresh air fan 6 allows outdoor air to enter the fresh air housing 8 through the fresh air inlet 801, and allows outdoor air entering the fresh air housing 8 to enter the room through the fresh air outlet 802. The rotation of the fresh air fan 6 provides driving force for the airflow.

[0138] In some embodiments, the fresh air housing 8 and the fresh air fan 6 are configured as a fresh air device. The fresh air fan 6 is disposed within the fresh air duct V01 and is used to drive airflow to be drawn in from the fresh air inlet 801 and discharged into the room through the fresh air outlet 802. The operation of the fresh air fan 6 provides the power for the flow of fresh air.

[0139] Therefore, by setting up a fresh air duct V01 in conjunction with a fresh air fan 6, when the indoor air is relatively polluted or the air quality is poor, the fresh air fan 6 can drive relatively fresh outdoor air into the indoor environment to improve the indoor airflow environment. The fresh air device can provide fresh air to the room.

[0140] A valve may be installed at least at one of the fresh air inlet 801 or fresh air outlet 802. By opening or closing the valve, the fresh air duct V01 can be opened or closed. Opening the fresh air duct V01 enables the fresh air mode; closing the fresh air duct V01 enables the fresh air mode to be closed.

[0141] In this application, the fresh air device of the wall-mounted air conditioner 10000 includes at least a fresh air fan 6, a second motor 5, and a fresh air housing 8. The fresh air device no longer uses a centrifugal fan, but adopts a diagonal flow fan structure, and the traditional volute structure is eliminated.

[0142] In the oblique flow fan of the fresh air device, the gas is drawn into the fresh air duct V01 and enters the fresh air fan 6. It rotates along the fresh air blades 62 of the fresh air fan 6 and generates wind pressure through the constraint and guidance of the fresh air housing 8.

[0143] Unlike centrifugal fans, which draw air in axially and expel it radially, diagonal-flow fans utilize an axial-in, axial-out path. This results in less impact on the fresh air blades 62 and the fresh air casing 8, reducing both power consumption and noise. Diagonal-flow fans also have a higher flow coefficient than centrifugal fans, allowing for a greater air volume.

[0144] Reference Figures 1-3 , Figure 9 As shown, panel 12 is provided with panel air outlet 121, and fresh air outlet 802 is connected to panel air outlet 121. Outdoor air inside fresh air housing 8 can be blown forward through fresh air outlet 802 and panel air outlet 121, so that the outdoor air entering fresh air housing 8 can be discharged from the front of main body 1000. In this way, the fresh air blown forward from panel air outlet 121 can directly blow on the user, or give the user a top-down shower breeze experience, resulting in a better user experience.

[0145] Panel 12 faces the user directly, and the panel air outlet 121 is a visible air outlet. By increasing the diameter of the panel air outlet 121, the air volume exiting from the panel air outlet 121 per unit time can be increased. Visualizing the fresh air can enhance the user's understanding of the fresh air device and allow them to experience the fresh air through their senses.

[0146] In some embodiments, the fresh air outlet 802 may also adopt a large diameter design, thereby reducing the wind speed appropriately when the air volume is constant, thus reducing the discomfort when the air is directly blown on the user.

[0147] In some embodiments, a mesh cover may also be provided on the panel 12. The mesh cover is provided over the air outlet 121 of the panel to block the air outlet 121 of the panel and prevent external dust and debris from falling into the fresh air outlet 802 through the air outlet 121 of the panel. The mesh cover has mesh holes that connect the air outlet 121 of the panel with the space outside the panel 12 so that the air at the air outlet 121 of the panel can be blown into the room through the mesh holes.

[0148] In this application, the fresh air fan 6 uses a diagonal-flow fan, so the exhausted air undergoes both centrifugal and axial motion. That is, the movement of the air exhausted from the fresh air outlet 802 into the room combines both axial and centrifugal motion. Axial motion helps to deliver air further, while centrifugal motion helps the exhausted air diffuse around the fresh air outlet 802, expanding the air delivery area. Therefore, when the panel outlet 121 is located on the panel 12, some fresh air is blown towards the front of the air conditioner and diffuses further, while some fresh air diffuses under centrifugal force, thus allowing fresh air to be distributed to a wider area.

[0149] Specifically, the part of the fresh air system that houses the diagonal flow fan is cylindrical in shape, has a compact structure, and occupies relatively little space.

[0150] According to the wall-mounted air conditioner 10000 of the present application embodiment, by connecting the fresh air outlet 802 with the panel outlet 121, air can be vented forward from the panel 12, and users can intuitively feel the fresh air, which is conducive to improving the user experience.

[0151] In some embodiments of this application, reference is made to Figures 9-16 As shown, the fresh air fan 6 includes a fresh air hub 61, which is connected to the output shaft 54. When the output shaft 54 ​​rotates, it drives the fresh air hub 61 to rotate, thereby driving the entire fresh air fan 6 to rotate.

[0152] The fresh air fan 6 also includes a fan outer cylinder 63. The fan outer cylinder 63 is arranged radially around the outside of the fresh air hub 61, forming a first airflow channel 64 between the fan outer cylinder 63 and the fresh air hub 61. One end of the first airflow channel 64 is a first airflow inlet 641, and the other end is a first airflow outlet 642, which connects to the panel air outlet 121. In the airflow path, the fresh air outlet 802 is located between the first airflow outlet 642 and the panel air outlet 121. Outdoor air entering the fresh air duct V01 from the fresh air inlet 801 can flow from the first airflow inlet 641 into the first airflow channel 64, then from the first airflow outlet 642 to the fresh air outlet 802, and finally to the panel air outlet 121, flowing into the indoor space through the panel air outlet 121.

[0153] Specifically, in the front-to-back direction of the wall-mounted air conditioner 10000, the rear end of the first airflow channel 64 is the first airflow inlet 641, and the front end of the first airflow channel 64 is the first airflow outlet 642.

[0154] The fresh air fan 6 also includes fresh air blades 62, which are located within the first airflow channel 64 and connect the fresh air hub 61 and the fan outer cylinder 63. When the fresh air fan 6 rotates, the fresh air blades 62 push the airflow, which can accelerate the airflow and increase the amount of air passing through the fresh air blades 62, thus improving the amount of fresh air supplied to the room by the fresh air device.

[0155] The first airflow channel 64 between the fresh air hub 61 and the fan outer cylinder 63 forms an annular channel, which can constrain and guide the circumferential flow of air. In this way, when the fresh air blades 62 drive the airflow to move axially, they can drive the airflow to move centrifugally. After the centrifugally moving airflow is constrained by the fresh air hub 61 and the fan outer cylinder 63, it can increase the airflow pressure and form a driving force to blow the airflow.

[0156] The fan outer casing 63 provides a stable channel for airflow, guiding it to flow in the designed direction. This allows the air to undergo both centrifugal and axial motion within the fresh air fan 6, achieving oblique flow. The fan outer casing 63 encloses the fresh air hub 61 and the fresh air blades 62, forming a relatively enclosed space. This effectively prevents airflow leakage from the periphery of the oblique flow fan, reduces airflow loss, and increases pressure and air volume output, enabling the fresh air fan 6 to more effectively deliver gas to the required locations.

[0157] The fresh air hub 61 also provides a stable channel for airflow, guiding it to flow in the designed direction. This allows airflow to pass more smoothly through the fresh air fan 6, reducing airflow turbulence and eddy currents, which helps improve the efficiency and performance of the fresh air fan 6, allowing the air to undergo both centrifugal and axial motion, achieving oblique flow.

[0158] The fresh air hub 61, the fan outer cylinder 63, and the fresh air blades 62 work together to change the speed and direction of the airflow, converting the kinetic energy of the airflow into static pressure energy. This increases the static pressure at the fresh air outlet 802, enhances the air delivery capacity of the fresh air fan 6, and enables the fresh air fan 6 to deliver air to a greater distance or overcome greater resistance.

[0159] Reference Figures 12-15 As shown, the fresh air hub 61 is provided with a mounting hole 6113, and the output shaft 54 ​​passes through the mounting hole 6113.

[0160] Reference Figure 12 As shown, the fresh air hub 61 includes a hub body portion 611, and a mounting hole 6113 is provided on the hub body portion 611, so that the hub body portion 611 is connected to the output shaft 54.

[0161] Reference Figure 12 As shown, the fresh air hub 61 also includes a hub expansion portion 612, which is connected to the outside of the hub body portion 611, and the fresh air blades 62 are disposed on the hub expansion portion 612.

[0162] The hub expansion portion 612 is tapered, with its smaller diameter end facing the fresh air inlet 801 and its larger diameter end facing the fresh air outlet 802. An accommodating space is formed within the hub expansion portion 612 to accommodate at least a portion of the structure of the second motor 5.

[0163] The hub body 611 includes a base plate 6111 and a mounting sleeve 6112. The mounting sleeve 6112 is connected to the base plate 6111, and a mounting hole 6113 is formed in the mounting sleeve 6112. The output shaft 54 ​​extends into the mounting hole 6113.

[0164] The hub body 611 also includes a rib 6114. The mounting sleeve 6112 and the base plate 6111 are connected by the rib 6114 to increase the overall strength of the fresh air hub 61. When the fresh air hub 61 is connected to the output shaft 54 ​​of the second motor 5, the power of the second motor 5 can be better transmitted to the fresh air hub 61, and the fresh air hub 61 is not easily deformed or damaged.

[0165] In some embodiments of this application, at least the fresh air hub 61 on the fresh air fan 6 is an integral injection molded part, and the output shaft 54 ​​is fixedly connected to the fresh air hub 61 by injection molding.

[0166] Reference Figures 12-15As shown, the fresh air hub 61 has a mounting hole 6113. The output shaft 54 ​​extends into the mounting hole 6113, and then the output shaft 54 ​​is fixedly connected to the mounting hole 6113 by injection molding, thus connecting the output shaft 54 ​​and the fresh air fan 6. Therefore, the connection between the output shaft 54 ​​and the fresh air fan 6 is firm, and they are unlikely to detach. This eliminates the need for periodic checks on whether the output shaft 54 ​​and the fresh air fan 6 are loose, reducing the chance of wear and tear on the fresh air fan 6 due to loosening.

[0167] In other embodiments, the output shaft 54 ​​passes through the mounting hole 6113 and is screwed onto the nut. Specifically, the output shaft 54 ​​passes through the mounting hole 6113 and has an external thread section. After the output shaft 54 ​​passes through the mounting hole 6113, the external thread section is screwed onto the nut, thereby better connecting and fixing the output shaft 54 ​​to the fresh air fan 6 and preventing the output shaft 54 ​​from disengaging from the fresh air fan 6. In the front-rear direction of the wall-mounted air conditioner 10000, the nut is located at the rear end of the fresh air fan 6.

[0168] Reference Figure 15 As shown, the fan outer casing 63 includes a first guide section 632 and a second guide section 633, which are connected to each other. Both the first guide section 632 and the second guide section 633 are conical cylinders. In the front-rear direction of the wall-mounted air conditioner 10000, the first guide section 632 is located behind the second guide section 633. The rear end of the first guide section 632 is the large-diameter end, and the front end of the first guide section 632 is the small-diameter end. The rear end of the second guide section 633 is the small-diameter end, and the front end of the second guide section 633 is the large-diameter end.

[0169] The rear end of the first guide section 632 is close to the fresh air inlet 801. In this way, the first guide section 632 can be used to guide airflow, making it easier for air from the fresh air inlet 801 to enter the first guide section 632. The large-diameter end of the first guide section 632 is designed to be streamlined, guiding the airflow smoothly into the fresh air fan 6.

[0170] The front end of the second guide section 633 is close to the fresh air outlet 802. In this way, the second guide section 633 can be used to guide the air, so that the air in the first airflow channel 64 can more easily reach the fresh air outlet 802.

[0171] In some embodiments of this application, reference is made to Figures 7-11 , Figure 17 As shown, the wall-mounted air conditioner 10000 also includes an air outlet guide 7, which is disposed in the accommodating cavity V1 and located between the fresh air fan 6 and the panel air outlet 121. The air outlet guide 7 is provided with a second airflow channel 74, which is connected to the first airflow channel 64 to guide the air in the fresh air housing 8 to the panel air outlet 121.

[0172] In the airflow path, the second airflow channel 74 is located between the first airflow outlet 642 and the panel air outlet 121. Outdoor air entering the fresh air duct V01 from the fresh air inlet 801 can flow into the first airflow channel 64 from the first airflow inlet 641, then into the second airflow channel 74 from the first airflow outlet 642, and then flow to the panel air outlet 121, and then into the indoor space through the panel air outlet 121.

[0173] In the front-to-back direction of the wall-mounted air conditioner 10000, the first airflow channel 64 is located at the rear end of the second airflow channel 74.

[0174] The air outlet guide 7 can rectify the airflow leaving the fresh air fan 6, making the airflow smoother, reducing airflow turbulence and eddies, improving the outlet pressure and efficiency of the fresh air fan 6, and also helping to reduce noise.

[0175] In some embodiments of this application, the air outlet guide 7 includes: an inner guide cylinder 71, an outer guide cylinder 73, and guide vanes 72. In the radial direction of the air outlet guide 7, the outer guide cylinder 73 is disposed around the outside of the inner guide cylinder 71, forming a second airflow channel 74 between the outer guide cylinder 73 and the inner guide cylinder 71. The guide vanes 72 are located within the second airflow channel 74, connecting the inner guide cylinder 71 and the outer guide cylinder 73. The guide vanes 72 can divide the second airflow channel 74 into multiple smaller channels, resulting in multiple streams of airflow being blown out, thereby improving the user's perceived comfort when fresh air is blown out. This avoids the discomfort caused to the user when a single stream of air is blown out directly without being divided into multiple streams.

[0176] The front end of the second airflow channel 74 faces the panel air outlet 121, and the rear end of the second airflow channel 74 faces the fresh air fan 6. When the fresh air fan 6 rotates, outdoor air enters the fresh air housing 8 from the fresh air inlet 801, passes through the first airflow channel 64 and the fresh air outlet 802, reaches the second airflow channel 74, and is then blown forward through the panel air outlet 121. This arrangement allows for a compact layout of the fresh air fan 6 and the air outlet guide 7, shortens the air outlet path, and reduces wind resistance.

[0177] The guide vanes 72 are designed to streamline and guide turbulent airflow, ensuring it flows smoothly and stably along the designed direction and path, thus reducing eddies and turbulence. The inner guide cylinder 71 and outer guide cylinder 73 form an annular second airflow channel 74, providing a stable channel for the airflow and guiding it to flow in the designed direction.

[0178] In this way, by rectifying the airflow, the airflow enters the room in a more ideal state, reducing the energy loss of the airflow during the flow process, thereby improving the overall efficiency of the diagonal flow fan.

[0179] The air outlet deflector 7 typically includes multiple guide vanes 72, which are evenly distributed around the first airflow outlet 642 of the fresh air fan 6. This even distribution ensures that the airflow is uniformly guided and rectified across the entire outlet cross-section, preventing airflow deviation or local turbulence.

[0180] In some embodiments of this application, reference is made to Figures 7-11 As shown, the inner circumferential surface of the outer guide cylinder 73 and the outer circumferential surface of the inner guide cylinder 71 both extend along the axial direction of the second motor 5 to guide the airflow within the second airflow channel 74 axially. In other words, the inner circumferential surface of the outer guide cylinder 73 and the outer circumferential surface of the inner guide cylinder 71 are both cylindrical surfaces, defining an annular channel extending along the axial direction of the second motor 5 between them. This allows the airflow to be blown out along the axial direction of the second motor 5, i.e., forward in a direction perpendicular to the panel 12. The blown airflow is more concentrated and less prone to dispersion, which helps to improve the user's perception of the fresh airflow.

[0181] In some embodiments of this application, reference is made to Figures 7-8 , Figure 11 As shown, the air outlet angle of the guide vane 72 is 0 degrees. In other words, the air outlet end of the guide vane 72 is parallel to the airflow direction at that location, so that the airflow blows forward in a direction perpendicular to the panel 12, making the blown airflow more concentrated and less prone to dispersion, which helps to improve the user's perception of fresh air.

[0182] In addition, the 0-degree outlet angle of the guide vane 72 can minimize the additional eddies and turbulence caused by the guiding effect of the guide vane 72 on the airflow, so that the airflow remains in a stable and orderly flow state, thereby reducing mutual interference and collision between airflows, reducing airflow noise, and making the diagonal flow fan run more quietly.

[0183] Specifically, the air inlet angle of the guide vane 72 is matched with the structural dimensions of the fresh air fan 6. Optionally, the air inlet angle of the guide vane 72 is 30 degrees to 50 degrees, and more preferably, the air inlet angle of the guide vane 72 is 40 degrees.

[0184] Optionally, the spacing d1 between adjacent guide vanes 72 can be 10mm-20mm, depending on the diameter ratio. (See reference here.) Figure 7A reference circle is drawn with the axis of the air outlet guide vane 7 as its center line. The arc length of this reference circle between two adjacent guide vanes 72 is the spacing d1. Typically, the spacing d1 between adjacent guide vanes 72 obtained on reference circles of different diameters will be unequal. For example... Figure 7 In the example shown, the spacing d1 between adjacent guide vanes 72 gradually increases in the radially outward direction.

[0185] Limiting the spacing d1 between adjacent guide vanes 72 to between 10mm and 20mm can match the structural parameter limitations of the fresh air unit in the wall-mounted air conditioner 10000. On the one hand, it ensures that the guide vanes 72 have a sufficient number of blades to better guide and rectify the airflow, and on the other hand, it leaves enough spacing between adjacent guide vanes 72 to reduce wind resistance.

[0186] In some embodiments of this application, reference is made to Figure 16 As shown, the fresh air blade 62 is a spiral blade. In this way, when the fresh air fan 6 rotates, the fresh air blade 62 can push the airflow, increase the air speed, which is conducive to increasing the air volume, and the spiral blade has good wind pressure capacity.

[0187] The fresh air blade 62 features an airfoil design with a spiral blade structure, allowing it to better adapt to airflow and reduce noise generated by airflow impact.

[0188] In some embodiments of this application, the stator 51 of the second motor 5 is connected to the air outlet guide 7. The stator 51 and the air outlet guide 7 may be directly connected or indirectly connected, and the stator 51 is fixed relative to the air outlet guide 7.

[0189] It is understandable that the air outlet guide 7 is installed on the fresh air housing 8, and the fresh air housing 8 is installed on the base. Installing the second motor 5 on the air outlet guide 7 is equivalent to indirectly installing it on the base, which can ensure the stability of the second motor 5 and reduce shaking.

[0190] Furthermore, the air outlet guide 7 is located at the air outlet end of the fresh air fan 6. The center of the air outlet end of the fresh air fan 6 is a windless zone. Therefore, by installing the second motor 5 on the air outlet guide 7, the second motor 5 can be positioned within the windless zone of the fresh air fan 6. On one hand, the second motor 5 does not need to be installed at the air inlet end of the fresh air fan 6, avoiding it becoming an obstruction to airflow. On the other hand, utilizing the windless zone allows the second motor 5 to be positioned closer to the fresh air fan 6, avoiding the formation of a large bending moment, reducing the swaying of the fresh air fan 6, and thus reducing the operating noise of the fresh air fan 6.

[0191] In some embodiments of this application, reference is made to Figure 9 , Figure 11As shown, the wall-mounted air conditioner 10000 also includes a motor bracket 91, which is located radially inside the air guide inner cylinder 71 and is connected to the air outlet guide 7. The motor bracket 91 is used to install the second motor 5.

[0192] The stator 51 is mounted on the motor bracket 91, and at least a portion of the output shaft 54, the rotor 52, the stator 51, and the motor housing 53 are located between the motor bracket 91 and the fresh air hub 61. This allows for full utilization of the space between the motor bracket 91 and the fresh air hub 61, which helps to reduce the axial dimension of the fresh air unit.

[0193] Reference Figure 9 , Figure 11 As shown, the second motor 5 is located at the rear of the air outlet guide 7, and the motor bracket 91 is located at the front of the air outlet guide 7. A first screw is passed through the first mounting hole on the motor bracket 91 and then tightened into the threaded hole on the air outlet guide 7 to fix the motor bracket 91 onto the air outlet guide 7. A second screw is passed through the second mounting hole on the motor bracket 91 and then tightened into the threaded hole 511 on the stator portion 51 to mount the stator portion 51 onto the motor bracket 91.

[0194] In some alternative embodiments, the second motor 5 is located on the rear side of the air outlet guide 7, and the motor bracket 91 is located on the front side of the air outlet guide 7. The stator portion 51 is mounted on the motor bracket 91 by using screws to pass through the mounting holes on the motor bracket 91 and the mounting holes on the air outlet guide 7 and then fastening them to the threaded holes 511 on the stator portion 51.

[0195] In some embodiments of this application, the motor bracket 91 is an integrally injection-molded metal bracket and vibration-damping rubber. Thus, after the second motor 5 is mounted on the motor bracket 91, the motor bracket 91 can dampen the vibration of the second motor 5 during operation.

[0196] In some embodiments of this application, reference is made to Figures 9-11 As shown, the fresh air hub 61 is a cylindrical body, specifically a conical body. The fresh air hub 61 is open at one end facing the air outlet 121 of the panel, and an accommodating space is formed inside the fresh air hub 61.

[0197] At least a portion of the second motor 5 is located within the fresh air hub 61. This saves on the axial dimension of the fresh air unit, reduces its axial space occupation, and prevents the wall-mounted air conditioner 10000 from becoming too thick. Furthermore, since at least a portion of the output shaft 54 ​​is located within the fresh air hub 61, the output shaft 54 ​​does not need to be excessively long, and the bending moment generated during rotation can be relatively small, thereby improving the dynamic stability of the fresh air fan 6.

[0198] It should be noted that when describing the internal structure of the fresh air device, the terms "axial", "radial", and "circumferential" are all based on the axial, radial, and circumferential directions of the second motor 5. That is, the direction parallel to the extension direction of the output shaft 54 ​​of the second motor 5 is the axial direction, the direction perpendicular to the extension direction of the output shaft 54 ​​is the radial direction, and the direction around the output shaft 54 ​​is the circumferential direction.

[0199] In some embodiments of this application, reference is made to Figure 9 , Figure 17 As shown, the air outlet guide 7 also includes a reinforcing ring 75, which connects to the inner guide cylinder 71. At least a portion of the stator 51, rotor 52, and motor housing 53 is located within the reinforcing ring 75. For example, at least a portion of one of the stator 51, rotor 52, and motor housing 53 may be located within the reinforcing ring 75; at least a portion of two of the stator 51, rotor 52, and motor housing 53 may be located within the reinforcing ring 75; or at least a portion of the stator 51, rotor 52, and motor housing 53 may all be located within the reinforcing ring 75. Therefore, the second motor 5 can occupy the space within the reinforcing ring 75, reducing the axial dimension of the fresh air unit and making the wall-mounted air conditioner 10000 more compact in the front-to-back direction.

[0200] In some embodiments not shown in the figures, the reinforcing ring 75 is located within the fresh air hub 61. This allows for a further reduction in the axial dimension of the fresh air unit.

[0201] In other embodiments of this application, reference is made to Figure 9 As shown, the reinforcing ring 75 is located outside the fresh air hub 61, and the end of the reinforcing ring 75 is positioned opposite to the end of the fresh air hub 61.

[0202] Combination Figure 9 , Figure 12 , Figure 17 The outer peripheral surface of the reinforcing ring 75 is the guide surface 751. The outer peripheral surface of the hub expansion portion 612 and the guide surface 751 form an almost continuous and smooth guide structure. When the airflow flows from the first airflow channel 64 to the second airflow channel 74, the airflow can flow through the outer peripheral surface of the hub expansion portion 612 and the guide surface 751 in sequence, thereby preventing abrupt changes in the airflow path.

[0203] In some embodiments of this application, reference is made to Figure 16 As shown, on the fresh air fan 6, the fresh air hub 61 and the fresh air blades 62 are integrally injection molded parts, while the fan outer cylinder 63 is an independent part, which is fixedly connected to the fresh air blades 62. This simplifies the processing and manufacturing difficulty of the fresh air fan 6.

[0204] Understandably, the fresh air hub 61 is connected to the second motor 5, serving as the power source for the fresh air fan 6. The fresh air blades 62, used to drive airflow, are the point of power consumption on the fresh air fan 6 and bear the greatest torque. Therefore, using a single injection molding process for the fresh air hub 61 and the fresh air blades 62 minimizes the risk of them becoming detached. Furthermore, making the fan outer cylinder 63 an independent component and processing it separately reduces the manufacturing difficulty of the fresh air fan 6 and lowers the scrap rate.

[0205] In some embodiments of this application, reference is made to Figure 16 As shown, the inner wall of the fan outer casing 63 has a locking hole 631, and the blade edge of the fresh air blade 62 has a locking block 621, which is inserted into the locking hole 631. The fresh air blade 62 is locked and fixed to the fan outer casing 63, which is convenient and quick to operate and helps to save the processing and manufacturing time of the fresh air fan 6. The number of locking blocks 621 on each fresh air blade 62 can be one or more, and the locking hole 631 corresponds one-to-one with the locking block 621. When there are multiple locking blocks 621 on each fresh air blade 62, the lengths of the multiple locking blocks 621 can be equal or unequal. For example, in Figure 16 In the middle, each fresh air blade 62 has two clips 621, and the lengths of the two clips 621 are not equal.

[0206] During assembly, assembly tools can be used to squeeze the fresh air blades 62 connected to the fresh air hub 61 into the fan outer cylinder 63, at which time the fan outer cylinder 63 is slightly stretched and deformed. When the block 621 is inserted into the locking hole 631, the fan outer cylinder 63 returns to its original shape and locks the fresh air blades 62.

[0207] Of course, the structure of the fresh air fan 6 is not limited to this, and the oblique flow fan structure known in the existing technology can also be adopted.

[0208] Specifically, the fresh air fan 6 can be made of plastic, thus being lightweight and low-cost. In some embodiments, the fresh air fan 6 can also be made of resin, metal, etc.

[0209] Specifically, the fresh air housing 8 can be made of plastic, thus being lightweight and low-cost. In some embodiments, the fresh air housing 8 can also be made of resin, metal, etc.

[0210] In some embodiments of this application, reference is made to Figures 9-10As shown, the fresh air fan 6 includes a first wind-blocking ring 65. The first wind-blocking ring 65 is arranged radially around the outside of the fan outer cylinder 63 and is connected to the fan outer cylinder 63. A first wind-blocking groove 66 is formed between the first wind-blocking ring 65 and the fan outer cylinder 63, and the opening of the first wind-blocking groove 66 faces the direction of the first airflow inlet 641. When the airflow passes over the outside of the fan outer cylinder 63, the first wind-blocking ring 65 can block the airflow, thereby reducing airflow noise. The airflow can briefly linger within the first wind-blocking groove 66, further achieving a noise reduction effect.

[0211] Furthermore, the first air baffle 66 effectively prevents airflow from flowing around the periphery of the fresh air fan 6, effectively preventing leakage from the high-pressure area of ​​the fresh air fan 6 to the low-pressure area, reducing gas leakage, and improving the efficiency and performance of the fresh air fan 6. When airflow attempts to flow towards the periphery of the fresh air fan 6, the airflow is blocked within the first air baffle 66, increasing flow resistance and thus reducing the possibility of leakage.

[0212] Optionally, the number of first air-blocking rings 65 can be one, two, or more. Such multiple barriers further increase flow resistance and further reduce the possibility of leakage. In addition, when the airflow passes through multiple first air-blocking slots 66, it is divided into multiple smaller airflows. These smaller airflows collide and rub against each other within the channel, causing the energy of the airflow to be consumed and attenuated to a certain extent, thereby reducing the noise generated by the airflow.

[0213] In some embodiments of this application, the fresh air housing 8 includes a second wind-blocking ring 83, which is disposed on the inner wall of the fresh air duct V01 and surrounds the outer side of the fan outer cylinder 63. At least a portion of the second wind-blocking ring 83 is located within the first wind-blocking groove 66. Thus, the second wind-blocking ring 83 and the first wind-blocking ring 65 form a multi-layered labyrinth structure. When airflow passes over the outer side of the fan outer cylinder 63, the second wind-blocking ring 83 and the first wind-blocking ring 65 can obstruct the airflow in multiple stages, reducing the gap between the outdoor fresh air entering the fresh air fan 6 and the fresh air housing 8, thereby reducing aerodynamic noise and further achieving a noise reduction effect.

[0214] The labyrinthine structure formed by the first air-blocking ring 65 and the second air-blocking ring 83 consists of multiple intersecting annular channels, further increasing the tortuosity of the airflow channels surrounding the fresh air fan 6. This causes the airflow to constantly change direction within the tortuous channels, further increasing flow resistance and thus reducing the possibility of leakage.

[0215] In some embodiments of this application, the flow area of ​​the first airflow channel 64 decreases in the direction from the first airflow inlet 641 to the first airflow outlet 642. Therefore, the first airflow channel 64 has a significant converging effect on the airflow, making it less likely for the airflow to disperse. This results in a higher wind speed at the first airflow outlet 642 than at the first airflow inlet 641. When the airflow exits from the fresh air outlet 802, the wind speed is higher, which helps to enhance the user's perception of fresh air and improve the user experience.

[0216] In some embodiments of this application, the flow area of ​​the second airflow channel 74 decreases in the direction from the first airflow channel 64 to the panel air outlet 121. Therefore, the second airflow channel 74 has a significant airflow-gathering effect, preventing the airflow from easily dissipating. This results in a higher wind speed at the outlet of the second airflow channel 74 than at its inlet. Consequently, the airflow exiting the panel air outlet 121 has a higher wind speed, which enhances the perceived fresh air flow and improves the user experience.

[0217] The air outlet guide 7 guides the high-speed rotating airflow accelerated by the oblique flow fan in the flow channel to be discharged towards the panel 12, optimizing the airflow characteristics and making the airflow direction more concentrated, continuous and stable.

[0218] The airflow exhausted by the fresh air system is in the form of a high-speed spiral diffusion. Based on the oblique flow fan, it can generate a large air volume and wind speed. The large exhaust area of ​​the air outlet is conducive to air diffusion, making it easier to mix with indoor air to form a more uniform airflow distribution, thereby improving the ventilation effect and reducing noise in the home environment.

[0219] By employing a diagonal flow fan and an air outlet guide 7, the exhaust noise is reduced, the wind speed is lower, the airflow noise is less, and the environment is quieter.

[0220] In some embodiments of this application, the wall-mounted air conditioner 10000 further includes a purification component 11, see reference. Figure 3 , Figure 9 , Figure 11 As shown, the purification component 11 is installed in the fresh air duct V01. The purification component 11 is used to purify the fresh air blown into the room and improve the cleanliness of the indoor air.

[0221] In some embodiments of this application, the purification component 11 is connected to the fresh air housing 8, which facilitates the assembly of the purification component 11 and prevents interference between the purification component 11 and the fresh air fan 6.

[0222] The purification component 11 is located at the axial air intake end of the fresh air fan 6. When the fresh air fan 6 rotates, outdoor air can enter the fresh air housing 8 from the fresh air inlet 801, and the outdoor air entering the fresh air housing 8 can be blown through the purification component 11 and then enter the room from the fresh air outlet 802 and the panel outlet 121, thereby improving the cleanliness of the indoor air.

[0223] In some embodiments of this application, the purification element 11 is vertically arranged and located behind the fresh air fan 6. This allows the fresh airflow to pass almost vertically over the purification element 11, further reducing fresh air intake consumption and increasing the fresh air volume. Furthermore, when the indoor heat exchanger 2 is in cooling mode, causing condensation in the fresh air, the condensation can remain on the purification element 11 as the air flows through it, further preventing water from being blown out of the fresh air unit.

[0224] For example, the purification component 11 includes a filter screen 111, such as Figure 3 The diagram shows the removal of filter 111 from the fresh air housing 8. When filter 111 is installed inside the fresh air housing 8, it covers the entire air intake end of the fresh air fan 6. Filter 111 has a large coverage area, resulting in a large filtration area and good filtration effect. The design of filter 111 helps ensure sufficient contact area with the flowing air, and it is lightweight and produces low noise. For example, filter 111 is made of HEPA mesh, thus possessing strong adsorption capacity and a strong filtration effect for dust in the air.

[0225] For example, filter 111 is plate-shaped, which makes filter 111 thinner overall, which helps to save on the axial dimensions of the fresh air system.

[0226] For example, the filter screen 111 is square, which makes it easy to position and install the filter screen 111. After it is fixed, it is not easy to shake and is easy to process, with less processing waste.

[0227] In some embodiments, the filter screen 111 is a square mesh. A square mesh is easy to position during fixing, does not easily shake after fixing, and is easy to process with minimal processing waste. The filter screen 111 covers the first airflow inlet 641 of the fresh air fan 6. The side length of the filter screen 111 is greater than the diameter of the first airflow inlet 641, ensuring that all fresh air entering the first airflow channel 64 flows through the filter screen 111 beforehand, resulting in high filtration cleanliness.

[0228] In some embodiments of this application, the fresh air housing 8 is provided with a first mounting port 803, through which the purification component 11 can be detachably mounted inside the fresh air housing 8. This facilitates the removal of the purification component 11 when it is damaged or saturated, making it convenient for repair or replacement.

[0229] In some embodiments of this application, reference is made to Figures 3-4 As shown, the bottom of the housing 1 is provided with a second mounting port 106, which is directly opposite the first mounting port 803. The purification component 11 is detachably assembled into the housing 1 through the second mounting port 106. The purification component 11 is installed radially inside the fresh air housing 8 along the second motor 5.

[0230] In related technologies, fresh air conditioners are limited by the centrifugal volute structure, with the purification component perpendicular to the base. This means that replacing the fresh air filter requires opening the panel, pulling out the filter holder, removing the old filter, replacing it with a new one, reinstalling the filter holder, and then closing the panel. This cumbersome filter replacement process leads some users to not replace their fresh air filters on time, resulting in poor fresh air performance. The wall-mounted air conditioner 10000 of this application allows for direct installation and removal of the purification component 11 and filter replacement from the bottom of the casing 1, without opening the panel 12, thus improving the convenience of replacing or repairing the purification component 11.

[0231] The wall-mounted air conditioner 10000 of this application adopts a brand-new architectural form. The purification component 11 is installed inside the fresh air housing 8 along the radial direction of the second motor 5. The diagonal flow fan is installed on the front side of the purification component 11 along the axial direction of the second motor 5. The air outlet direction of the entire fresh air device is the axial direction of the second motor 5. The purification component 11 can be perpendicular to the base. The filter can be replaced by pulling out the purification component 11 from the second installation port 106 without opening the panel 12. The time for replacing the filter is shortened from 3 minutes to 20 seconds, and the maintenance efficiency is improved by 15 times.

[0232] In some embodiments of this application, reference is made to Figures 1-4 As shown, the front of the casing 1 is provided with a casing air outlet 105. The fresh air outlet 802, the casing air outlet 105, and the panel air outlet 121 are connected to each other so that air can be discharged forward through the casing air outlet 105 and the panel air outlet 121. In a plane perpendicular to the front and rear direction of the wall-mounted air conditioner 10000, the projections of the inner peripheral walls of the fresh air outlet 802, the casing air outlet 105, and the panel air outlet 121 on this plane at least partially overlap, thereby allowing air to be discharged forward smoothly.

[0233] Panel 12 can be opened or closed. When panel 12 is open, the air outlet 105 of the casing can be exposed.

[0234] In some embodiments, the panel 12 can be detached from the housing 1 to open the panel 12.

[0235] In other embodiments, panel 12 can be opened by pushing or pulling.

[0236] In some other embodiments, the panel 12 is rotatably connected to the housing 1, and the panel 12 can be opened by rotating upwards.

[0237] In some embodiments of this application, the fresh air housing 8 includes a first housing portion 81, the front of the first housing portion 81 is open, and the bottom of the first housing portion 81 is provided with a fresh air inlet 801.

[0238] The cavity formed by the first shell 81 is located at the air inlet of the fresh air fan 6. This cavity can be used to contain air, allowing air to enter the fresh air fan 6 vertically along the axial direction from the first shell 81, thereby improving the air intake efficiency of the fresh air fan 6 and reducing air intake loss.

[0239] When the wall-mounted air conditioner 10000 includes the purification component 11, the purification component 11 is installed inside the first housing 81. This separate installation facilitates assembly.

[0240] The fresh air housing 8 also includes a duct connector 84. The bottom of the first housing 81 is provided with an interface 811, and the duct connector 84 is connected to the interface 811. The air inlet of the duct connector 84 can be formed as a fresh air inlet 801.

[0241] In some embodiments, the wall-mounted air conditioner 10000 may include: a fresh air inlet pipe (not shown) connected to the duct connector 84, and a duct clearance opening (not shown) provided on the side wall (e.g., the right side wall or the left side wall) of the housing 1. After the fresh air inlet pipe is connected to the fresh air inlet 801 from the bottom of the main body 1000, it bends and extends laterally, then extends out from the duct clearance opening on the side wall of the housing 1, and then extends to the outside.

[0242] In some embodiments, the fresh air inlet 801 is located at the bottom of the main body 1000 and is positioned near the rear side, so that after the fresh air inlet 801 is connected to the fresh air introduction pipe, it is convenient for the fresh air introduction pipe to be arranged close to the wall.

[0243] It is understandable that the main body 1000 is usually equipped with a refrigerant pipe and a drain pipe at one end in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 to the outdoor compressor and outdoor heat exchanger, and the drain pipe is used to drain the condensate generated inside the wall-mounted air conditioner 10000.

[0244] The duct clearance opening is located on the side wall of the casing 1. Then, the fresh air inlet duct is laid horizontally and led out, making it easy to place at least one of the fresh air inlet ducts alongside the drain pipe and refrigerant pipe. In this way, the multiple pipes are wrapped with an external bundle or strap, so that the multiple pipes appear as a single pipe. This reduces the number of connecting pipes on the wall-mounted air conditioner 10000 after installation, resulting in a simple appearance. This not only facilitates assembly but also avoids the risk of multiple pipes bumping into each other.

[0245] The fresh air housing 8 also includes a second housing portion 82, which is connected to the front of the first housing portion 81. The fresh air fan 6 is located inside the second housing portion 82. The front of the second housing portion 82 is open to form a fresh air outlet 802, which is positioned directly opposite the panel outlet 121.

[0246] In some embodiments of this application, such as Figures 9-11As shown, the first shell portion 81 includes a first half-shell 812 and a second half-shell 813. The first half-shell 812 is located behind the second half-shell 813 and is connected to it. The first mounting opening 803 can be formed by the first half-shell 812 and the second half-shell 813, or it can be located on one of the first half-shell 812 and the second half-shell 813. By configuring the first shell portion 81 as a two-half-shell structure, the manufacturing of the first shell portion 81 can be facilitated.

[0247] For example, the first half-shell 812 and the second half-shell 813 are detachably connected. This detachable connection facilitates assembly and subsequent adjustments and maintenance.

[0248] In some embodiments of this application, such as Figures 9-11 As shown, the second shell portion 82 includes a third half-shell 821 and a fourth half-shell 822. The third half-shell 821 is located behind the fourth half-shell 822. The third half-shell 821 is connected to the second half-shell 813, and the third half-shell 821 is connected to the fourth half-shell 822. The fourth half-shell 822 is connected to the air outlet guide 7. By configuring the second shell portion 82 as a two-half-shell structure, the manufacturing of the second shell portion 82 can be facilitated.

[0249] For example, the third half-shell 821 is detachably connected to the second half-shell 813, the third half-shell 821 is detachably connected to the fourth half-shell 822, and the fourth half-shell 822 is detachably connected to the air outlet guide 7. The detachable connection method facilitates assembly and subsequent adjustment and maintenance.

[0250] By setting the fresh air housing 8 into multiple housings, it is convenient to process and manufacture the fresh air housing 8, and also convenient to install and disassemble the internal components of the fresh air housing 8.

[0251] The two parts mentioned in this application can be detachably connected using a bolt structure, a snap-fit ​​structure, or other detachable methods, which will not be listed here.

[0252] In some embodiments of this application, such as Figure 1-Figure 2 As shown, the wall-mounted air conditioner 10000 also includes an air guide plate 13, the left and right ends of which are pivotally connected to the casing 1. The air guide plate 13 is rotatable relative to the casing 1. When the air guide plate 13 is rotated to the open state, the heat exchange air outlet 102 is exposed, facilitating airflow from the heat exchange air outlet 102. When the air guide plate 13 is rotated to the closed state, the heat exchange air outlet 102 is blocked, preventing debris, flying insects, etc., from entering the interior of the wall-mounted air conditioner 10000 when the heat exchange air outlet 102 is exposed when the wall-mounted air conditioner 10000 is not in operation.
