[0004] The present application aims to at least solve one of the above technical problems in the prior art to some extent. To this end, the present application provides a wall-mounted air conditioner, and the user can intuitively feel the fresh air.

[0005] The wall-mounted air conditioner according to an embodiment of the present application includes a main body, the main body includes a cabinet, an accommodation cavity is formed in the interior of the cabinet, and a heat exchange air inlet and a heat exchange air outlet are formed on the cabinet. The cabinet can protect the components in the accommodation cavity and constitute the overall appearance structure of the wall-mounted air conditioner.

[0006] The main body further includes an indoor heat exchanger, and the indoor heat exchanger is arranged in the accommodation cavity. The indoor heat exchanger is a ring in a refrigerant circuit, and the interior of the indoor heat exchanger circulates refrigerant, which is used to cool or heat the air circulating on the surface of the indoor heat exchanger.

[0007] The main body further includes a heat exchange fan, the heat exchange fan is configured to suck indoor air from the heat exchange air inlet into the main body and send the indoor air after heat exchange with the indoor heat exchanger to the indoor through the volute tongue air duct and the heat exchange air outlet, and the heat exchange fan provides power for the flow of the indoor air.

[0008] The main body further includes a first motor, the first motor is arranged in the accommodation cavity, and the first motor is used to drive the heat exchange fan to rotate so that the air in the air conditioner exchanges heat with the indoor heat exchanger.

[0009] The main body further includes a panel, and the panel is mounted on the front side of the cabinet. The panel is the main appearance of the wall-mounted air conditioner and can shield the cabinet and the components in the accommodation cavity.

[0010] The wall-mounted air conditioner further includes a second motor, the second motor is located at one end in the length direction of the main body, the second motor is an inner rotor motor, and the second motor includes an output shaft.

[0011] The wall-mounted air conditioner further comprises a fresh air fan, the fresh air fan is a mixed flow fan, and the fresh air fan is connected with the output shaft of the second motor. The output shaft can drive the fresh air fan to rotate synchronously.

[0012] The wall-mounted air conditioner further comprises a fresh air shell, a fresh air air duct is formed in the fresh air shell, the fresh air fan is installed in the fresh air shell, and a fresh air inlet and a fresh air outlet are formed in the fresh air shell. The fresh air inlet and the fresh air outlet are connected with the fresh air air duct, outdoor air enters the fresh air air duct through the fresh air inlet, and the outdoor air in the fresh air air duct is blown into an indoor space through the fresh air outlet.

[0013] Rotation of the fresh air fan enables outdoor air to enter the fresh air shell from the fresh air inlet and enables the outdoor air in the fresh air shell to enter the indoor space from the fresh air outlet. The fresh air fan provides driving force for air flow when rotating.

[0014] The fresh air outlet is connected with the panel outlet, and the outdoor air in the fresh air shell can be blown out of the fresh air outlet and the panel outlet to the front, so that the outdoor air in the fresh air shell is discharged from the front side of the main body. In this way, the fresh air blown out of the panel outlet can directly blow on the user or give the user a top-down showering air experience, and the user can intuitively feel the fresh air, and the user experience is better.

[0015] According to the wall-mounted air conditioner provided in the embodiments of the present application, the fresh air outlet is connected with the panel outlet, air can be discharged from the front of the panel, the user can intuitively feel the fresh air, and the user experience is improved.

[0016] In the present application, the fresh air fan is a mixed flow fan, and the discharged air performs both centrifugal motion and axial motion, that is, the motion of the air discharged from the fresh air outlet to the indoor space is a combination of axial flow and centrifugal motion. The axial motion of the air is beneficial to sending the air farther, and the centrifugal motion of the air is beneficial to diffusing the air around the panel outlet after the air is discharged, thereby expanding the air supply area.

[0017] According to some embodiments of the present application, the fresh air fan comprises a fresh air hub, and the fresh air hub is connected with the output shaft. The output shaft drives the fresh air hub to rotate, so as to drive the fresh air fan to rotate as a whole.

[0018] The fresh air fan further comprises a fan outer cylinder, which is arranged outside the fresh air hub in the radial direction of the fresh air hub, and a first air flow channel is formed between the fan outer cylinder and the fresh air hub, one end of the first air flow channel being a first air flow inlet and the other end being a first air flow outlet, and the first air flow outlet being communicated with the panel air outlet. The outdoor air entering the fresh air duct from the fresh air inlet can flow into the first air flow channel from the first air flow inlet, then flow to the fresh air outlet from the first air flow outlet, and then flow to the panel air outlet, and then flow into the indoor space through the panel air outlet.

[0019] The fresh air fan further comprises a fresh air blade, which is located in the first air flow channel and connected to the fresh air hub and the fan outer cylinder. When the fresh air fan rotates, the fresh air blade pushes the air flow to accelerate the air flow, so that the air volume passing through the fresh air blade increases, which is beneficial to increase the fresh air volume provided by the fresh air device to the indoor space.

[0020] According to some embodiments of the present application, the fresh air hub comprises a hub body part, and a mounting hole is arranged on the hub body part.

[0021] The fresh air hub further comprises a hub outer expansion part, which is connected to the outer side of the hub body part, and the fresh air blade is arranged on the hub outer expansion part. The hub outer expansion part is conical, the small-diameter end of the hub outer expansion part faces the fresh air inlet, and the large-diameter end of the hub outer expansion part faces the fresh air outlet.

[0022] According to some embodiments of the present application, the wall-mounted air conditioner further comprises an air outlet flow guide, which is arranged in the accommodating cavity and located between the fresh air fan and the panel air outlet. A second air flow channel is arranged in the air outlet flow guide, and the second air flow channel is communicated with the first air flow channel to guide the air in the fresh air shell to the panel air outlet.

[0023] In the flow path of the air flow, the second air flow channel is located between the first air flow outlet and the panel air outlet. The outdoor air entering the fresh air duct from the fresh air inlet can flow into the first air flow channel from the first air flow inlet, then flow into the second air flow channel from the first air flow outlet, and then flow to the panel air outlet, and then flow into the indoor space through the panel air outlet.

[0024] The air outlet flow guide can straighten the air flow leaving the fresh air fan, so that the air flow is more smooth, the turbulence and vortex of the air flow are reduced, the outlet pressure and efficiency of the fresh air fan are improved, and the noise is also reduced.

[0025] According to some embodiments of the present application, the air outlet flow guide comprises a flow guide inner cylinder, a flow guide outer cylinder and a flow guide blade. The flow guide outer cylinder is arranged outside the flow guide inner cylinder in the radial direction of the air outlet flow guide. A second air flow channel is formed between the flow guide inner cylinder and the flow guide outer cylinder. The flow guide blade is located in the second air flow channel and is connected to the flow guide inner cylinder and the flow guide outer cylinder. The arrangement of the flow guide blade can increase the number of small channels into which the second air flow channel is divided, and the air flow is divided into multiple air streams, thereby improving the perceived comfort of the user when the fresh air is blown out and avoiding the discomfort of the user caused by the direct blowing of a whole air stream.

[0026] The front end of the second air flow channel is arranged towards the panel air outlet, and the rear end of the second air flow channel is arranged towards the fresh air fan. When the fresh air fan rotates, outdoor air enters the fresh air shell from the fresh air inlet, passes through the first air flow channel, the fresh air outlet and the second air flow channel in sequence, and is blown out forward through the panel air outlet.

[0027] According to some embodiments of the present application, the inner circumferential surface of the flow guide outer cylinder and the outer circumferential surface of the flow guide inner cylinder extend in the axial direction of the second motor to axially guide the air flow in the second air flow channel. Thus, the air is blown out in the axial direction of the second motor, that is, the flow is blown out forward in a direction perpendicular to the panel. The blown air flow is more concentrated and less likely to disperse, which is conducive to improving the perceived fresh air wind of the user.

[0028] According to some embodiments of the present application, the fresh air blade is a spiral blade. In this way, when the fresh air fan rotates, the fresh air blade can push the air flow, which can increase the speed of the air and increase the air volume. The spiral blade has good wind pressure capacity.

[0029] According to some embodiments of the present application, the wall-mounted air conditioner further comprises a motor support, which is located on the radially inner side of the flow guide inner cylinder and is connected to the air outlet flow guide. The motor support is used to install the second motor.

[0030] The second motor comprises a stator portion, which is installed on the side of the motor support away from the fresh air hub. Thus, the motor support can hold the stator portion, thereby supporting the entire second motor. Moreover, the axial distance between the installation and fixing point of the second motor and the connection position of the fresh air fan is short, which is conducive to reducing the rotation bending moment and improving the stability.

[0031] The air outlet flow guide further comprises a support plate connected to the radially inner side of the flow guide inner cylinder. The stator portion is clamped between the motor support and the support plate. In this way, the axial ends of the stator portion are in a fixed state, which further improves the installation stability of the second motor and reduces the shaking during operation.

[0032] According to some embodiments of the present application, the new air fan, the new air hub and the new air blade are an integral injection molding part, the fan outer barrel is a separate part, and the fan outer barrel is fixedly connected to the new air blade. Thus, the processing and manufacturing difficulty of the new air fan can be simplified.

[0033] According to some embodiments of the present application, the inner wall of the fan outer barrel is provided with a clamping hole, the edge of the new air blade is provided with a clamping block, and the clamping block is inserted into the clamping hole. The new air blade is clamped and fixed with the fan outer barrel, which is convenient and quick to operate, and is beneficial to save the processing and manufacturing time of the new air fan.

[0034] According to some embodiments of the present application, the new air fan comprises a first wind resistance ring, which is arranged outside the fan outer barrel in the radial direction of the new air hub and is connected to the fan outer barrel. A first wind resistance groove is formed between the first wind resistance ring and the fan outer barrel, and the opening of the first wind resistance groove is arranged towards the direction of the first air inlet. When the airflow flows outside the fan outer barrel, the first wind resistance ring can block the airflow, thereby reducing the airflow noise. The airflow can stay in the first wind resistance groove for a short time, thereby further achieving the noise reduction effect. When the airflow tries to flow to the periphery of the new air fan, the airflow will be blocked in the first wind resistance groove, increasing the flow resistance and thereby reducing the possibility of leakage.

[0035] According to some embodiments of the present application, the new air shell comprises a second wind resistance ring, which is arranged on the inner wall of the new air duct. The second wind resistance ring is arranged outside the fan outer barrel, and at least part of the second wind resistance ring is located in the first wind resistance groove. Thus, a structure similar to a seal is formed between the second wind resistance ring and the first wind resistance ring. When the airflow flows outside the fan outer barrel, the second wind resistance ring and the first wind resistance ring can block the airflow in multiple stages, further increasing the flow resistance and thereby further achieving the noise reduction effect.

[0036] According to some embodiments of the present application, in the direction from the first air inlet to the first air outlet, the flow area of the first air flow channel shows a decreasing trend. Thus, the first air flow channel has a clear effect of gathering airflow, and the airflow is not easy to spread out, so that the wind speed at the first air outlet is greater than the wind speed at the first air inlet. When the airflow is blown out from the new air outlet, the wind speed is large, which is beneficial to improve the new air feeling experienced by the user and improve the user experience.

[0037] According to some embodiments of the present application, the wall-mounted air conditioner further comprises a purifying element installed in the fresh air duct, which is used to purify the fresh air blown into the room, thereby improving the cleanliness of the indoor air. The purifying element is connected to the fresh air casing and is located at the axial air inlet end of the fresh air fan. The fresh air fan rotates to allow outdoor air to enter the fresh air casing from the fresh air inlet, and the outdoor air entering the fresh air casing is blown through the purifying element and then enters the room from the fresh air outlet and the panel outlet, thereby improving the cleanliness of the indoor air.

[0038] According to some embodiments of the present application, the purifying element is vertically arranged and located behind the fresh air fan. In this way, the fresh air flow can almost vertically pass through the purifying element, and the fresh air inlet consumption can be further reduced, thereby increasing the fresh air volume. Moreover, when the indoor heat exchanger is in a refrigeration state and condensate water is generated in the fresh air, the condensate water can be left on the purifying element when the air flows through the purifying element, thereby further avoiding the blowing of water when the fresh air device blows out.

[0039] According to some embodiments of the present application, the fresh air casing is provided with a first mounting opening, and the purifying element is detachably assembled in the fresh air casing through the first mounting opening. In this way, when the purifying element is damaged or saturated, the purifying element can be easily disassembled for maintenance or replacement.

[0040] According to some embodiments of the present application, the bottom of the casing is provided with a second mounting opening opposite to the first mounting opening, and the purifying element is detachably assembled in the casing through the second mounting opening. In this way, the purifying element can be directly assembled and disassembled from the bottom of the casing without opening the panel, thereby improving the convenience of replacing or maintaining the purifying element.

[0041] According to some embodiments of the present application, the fresh air casing comprises a first casing portion, the front of the first casing portion is open, and the fresh air inlet is arranged at the bottom of the first casing portion.

[0042] The fresh air casing further comprises a second casing portion connected to the front of the first casing portion, the fresh air fan is located in the second casing portion, the front of the second casing portion is open to form the fresh air outlet, and the fresh air outlet is arranged opposite to the panel outlet.

[0043] By arranging the fresh air casing into multiple casing portions, the processing and manufacturing of the fresh air casing can be facilitated, and the installation and disassembly of the internal components of the fresh air casing can also be facilitated.

[0044] Additional aspects and advantages of the present application will be in part apparent and in part pointed out hereinafter. BRIEF DESCRIPTION OF DRAWINGS

[0073] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components are denoted by the same or similar reference numerals throughout the drawings. The embodiments described below are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0074] In the description of the present application, the terms "first", "second" are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0075] Some embodiments of the present application provide a wall-mounted air conditioner 10000.

[0076] Generally, the air conditioner is a split-type air conditioner, including an indoor unit and an outdoor unit, the indoor unit and the outdoor unit are connected by a pipeline to transmit refrigerant, the indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0077] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan and a throttling device, the compressor, the outdoor heat exchanger, the throttling device and the indoor heat exchanger connected in sequence form a refrigerant circuit, the refrigerant circulates in the refrigerant circuit, and the outdoor heat exchanger and the indoor heat exchanger respectively exchange heat with air to realize the cooling mode or the heating mode of the air conditioner.

[0078] The compressor is configured to compress the refrigerant to form high-pressure refrigerant by compressing low-pressure refrigerant.

[0079] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transmitted in the outdoor heat exchanger, for example, the outdoor heat exchanger works as a condenser in the cooling mode of the air conditioner, so that the refrigerant compressed by the compressor is condensed by dissipating heat to the outdoor air through the outdoor heat exchanger. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the refrigerant after pressure reduction is evaporated by absorbing the heat of the outdoor air through the outdoor heat exchanger.

[0080] In some embodiments, the outdoor heat exchanger can include heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0081] The outdoor fan is configured to suck the external air into the outdoor unit and send the outdoor air after heat exchange with the outdoor heat exchanger to the outside, and the outdoor fan provides power for the flow of the outdoor air.

[0082] The throttling device is connected between the outdoor heat exchanger and the indoor heat exchanger, and is used to adjust the pressure of the refrigerant flowing through the outdoor heat exchanger and the indoor heat exchanger, so as to adjust the flow rate of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger will affect the heat exchange performance of the outdoor heat exchanger and the indoor heat exchanger. The throttling device can be a throttling pipe, an electronic valve, etc. When the throttling device is an electronic valve, the opening degree of the throttling device is adjustable, so as to adjust the flow rate and pressure of the refrigerant flowing through the throttling device.

[0083] In some solutions, the air conditioner can include a four-way valve connected in the refrigerant circuit, and the four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit to make the air conditioner perform a cooling mode or a heating mode.

[0084] The indoor heat exchanger is configured to exchange heat between indoor air and the refrigerant transmitted in the indoor heat exchanger. In some embodiments, the indoor heat exchanger can include heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0085] The heat exchange fan is configured to suck indoor air into the indoor unit and send the indoor air exchanged with the indoor heat exchanger to the indoor, and the heat exchange fan provides power for the flow of the indoor air.

[0086] The air conditioner can include a control device mainly used to control the working frequency of the compressor, the opening degree of the throttling device, and the control device can also control the rotating speed of the outdoor fan and the rotating speed of the heat exchange fan, etc. The control device is connected with the compressor, the throttling device, the motor driving the outdoor fan to rotate, and the motor driving the heat exchange fan to rotate through data lines to transmit communication information.

[0087] The control device includes a processor, which can include a central processing unit (CPU), a microprocessor, an application specific integrated circuit (ASIC), and can be configured to perform the corresponding operations described in the control device when the processor executes the program stored in the non-transitory computer readable medium coupled to the control device.

[0088] The non-transitory computer readable storage medium can include a magnetic storage device (e.g., a hard disk, a floppy disk, or a magnetic tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory, a card, a stick, or a keyboard drive).

[0089] At present, most of the wall-mounted air conditioners are limited by volume and weight, and the functions that can be realized are relatively limited, and usually only indoor air can be cooled or heated. If the user feels that the indoor air is relatively dirty and stuffy after turning on the air conditioner for a long time, he needs to open the window for ventilation, which is not only troublesome, but also the indoor cold air or warm air will quickly flow out of the window during the opening of the window, affecting people's comfort.

[0090] Some fresh air air conditioners in the related art inhale fresh air from the outdoor through a fresh air device. However, the user cannot intuitively feel the fresh air, resulting in poor user experience.

[0091] To solve the above problems, some embodiments of the present application provide a wall-mounted air conditioner 10000, which can intuitively feel fresh air, which is beneficial to improve user experience.

[0092] For example, the wall-mounted air conditioner 10000 is a kind of indoor unit. The wall-mounted air conditioner 10000 is usually installed on the wall, for example, can be installed in the upper region of the indoor wall.

[0093] The wall-mounted air conditioner 10000 according to the embodiments of the present application is described in detail below. Figures 1-21 The wall-mounted air conditioner 10000 according to the embodiments of the present application is described in detail below.

[0094] Referring to Figures 1-3 , the wall-mounted air conditioner 10000 according to the embodiments of the present application includes a main body 1000, the main body 1000 includes a shell 1, the inside of the shell 1 forms a receiving cavity V1, and the shell 1 forms a heat exchange air inlet 101 and a heat exchange air outlet 102. The shell 1 can play a role in protecting the components in the receiving cavity V1, and constitutes the overall appearance structure of the wall-mounted air conditioner 10000.

[0095] Usually, the shell 1 is a long strip-shaped shell, the length direction of the shell 1 is arranged along the horizontal direction, that is, the shell 1 is installed on the wall along the transverse direction. In actual products, in order to discharge condensate water, the shell 1 in some embodiments is installed on the wall along the transverse direction and forms a small angle with the horizontal plane.

[0096] Referring to Figures 4-6 , the main body 1000 further includes an indoor heat exchanger 2, and the indoor heat exchanger 2 is arranged in the receiving cavity V1. As described above, the indoor heat exchanger 2 is a ring in the refrigerant circuit, the inside of the indoor heat exchanger 2 circulates refrigerant, and is used for cooling or heating the air flowing through the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is usually arranged along the length direction of the shell 1.

[0097] 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.

[0098] The main body 1000 further comprises a base arranged in the accommodating cavity V1, and a volute air duct is formed in the base. The base is a mounting and supporting structure inside the main body 1000, and the indoor heat exchanger 2 can be mounted on the base. After the indoor air enters the casing 1, the flow direction of the indoor air is guided by the volute air duct, so that the indoor air flows through the indoor heat exchanger 2 with relatively small resistance.

[0099] With reference to Figures 5-6 The main body 1000 further comprises a heat exchange fan 41 arranged in the volute air duct. The heat exchange fan 41 is configured to suck the indoor air from the heat exchange air inlet 101 into the main body 1000, and send the indoor air after heat exchange with the indoor heat exchanger 2 to the indoor space through the heat exchange air outlet 102, specifically through the volute air duct and the heat exchange air outlet 102. The heat exchange fan 41 provides power for the flow of the indoor air.

[0100] In some embodiments, the heat exchange fan 41 is, for example, a cross-flow fan, which has low noise and large air volume, and the air outlet speed of the cross-flow fan is distributed relatively uniformly along the axial direction of the cross-flow fan, which is beneficial to increase the air supply distance and range. Moreover, in the case of using the cross-flow fan and arranging the cross-flow fan along the length direction of the heat exchange fan 41, the airflow driven by the cross-flow fan can flow through the entire indoor heat exchanger 2, thereby ensuring the balance of heat exchange efficiency of the indoor heat exchanger 2 at different positions.

[0101] The main body 1000 further comprises a first motor arranged in the accommodating cavity V1, and the first motor is used to drive the heat exchange fan 41 to rotate, so that the air in the air conditioner is heat exchanged with the indoor heat exchanger 2.

[0102] By arranging the heat exchange air outlet 102 and the heat exchange air inlet 101 in the casing 1, the heat exchange fan 41 can suck the indoor air from the heat exchange air inlet 101 into the casing 1 when the heat exchange fan 41 is running. After the indoor air is heat exchanged with the indoor heat exchanger 2, the heat exchanged air is sent to the indoor space through the heat exchange air outlet 102.

[0103] Therefore, the adjustment of the indoor environment temperature can be realized. The indoor heat exchanger 2 can be used as an evaporator to provide a refrigeration airflow to the indoor space through the heat exchange air outlet 102, or the indoor heat exchanger 2 can be used as a condenser to provide a heating airflow to the indoor space through the heat exchange air outlet 102.

[0104] In some embodiments, in the height direction of the main body 1000, the heat exchange air inlet 101 is located above the heat exchange air outlet 102, so that the air is inhaled from the top and discharged from the bottom.

[0105] For example, the height direction of the main body 1000 is the up-down direction.

[0106] It can be understood that the main body 1000 is usually installed on a wall, and in order to avoid interfering with people's daily life, the main body 1000 is usually hung at a high position. By setting the main body 1000 to blow out the heat exchange air from below, the blown heat exchange air is not easily blocked by the roof and the ground, so that the heat exchange air has small resistance consumption during blowing and has a wide blowing range, so that the heat exchange air can flow to the entire indoor space as soon as possible, thereby improving the heat exchange efficiency.

[0107] With reference to Figure 1 and Figure 4 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air inlet 101 can take in air from above, so that air is not taken in from the heat exchange air outlet 102, and the heat exchange air blown out from the heat exchange air outlet 102 is not directly sucked into the heat exchange air inlet 101, thereby reducing the idle rotation of the heat exchange air and the process of not participating in indoor heat exchange.

[0108] In some embodiments, as shown in Figure 1 , the heat exchange air inlet 101 is located at the top of the casing 1, that is, in an area that cannot be seen by a user, and the heat exchange air inlet 101 is hidden, thereby improving the appearance of the wall-mounted air conditioner 10000.

[0109] In some embodiments not shown in the figure, the heat exchange air outlet 102 is located in front of the casing 1, that is, the heat exchange air outlet 102 blows air to the front side of the main body 1000.

[0110] It can be understood that the side of the main body 1000 connected to the wall is usually called the back or the rear side, and the side opposite to the rear side is called the front side, so when the heat exchange air outlet 102 is located in front of the casing 1, the air outlet is away from the wall, and the blowing resistance is small and the blowing range is wide.

[0111] In some embodiments, the heat exchange air outlet 102 is located on the front side of the casing 1 and close to the bottom, for example, as shown in Figure 4 , 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 by the heat exchange air outlet 102 flows forward and downward at the same time, so that the heat exchange air can sink and fall on a person or object on the ground after being sent to a certain distance, so that the person or object on the ground can be in the suitable indoor environment as soon as possible.

[0112] 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 can be understood that the heat exchange fan 41 is a power driven member for driving the indoor air to exchange heat with the indoor heat exchanger 2, and is also a power driven member for blowing air.

[0113] The heat exchange fan 41 is arranged at a side of the indoor heat exchanger 2 away from the heat exchange air inlet 101, so that the air power generated when the heat exchange fan 41 rotates can be evenly distributed, a part of which is distributed to the air inlet side to enable the inhaled air to overcome the air resistance generated by the indoor heat exchanger 2 when flowing into the volute tongue air duct, and another part of which is distributed to the air outlet side to enable the heat exchanged air to be blown out from the heat exchange air outlet 102 when the air is transported over a long distance.

[0114] In some embodiments, the first motor is located at one end of the heat exchange fan 41 in the length direction, for example, the right end. In this way, the installation and maintenance of the first motor are facilitated, and the main body 1000 as a whole does not need to become too high and thick due to the arrangement of the first motor. Here, the height direction of the main body 1000 is consistent with the up-down direction, and the thickness direction of the main body 1000 is consistent with the front-rear direction.

[0115] It can be understood that the wall-mounted air conditioner 10000 is generally in a long strip shape, the length direction of the heat exchange fan 41 is the same as the length direction of the main body 1000, and both are the left-right direction shown in Figures 1-2 、 Figures 5-6 .

[0116] The main body 1000 further includes a panel 12, which is arranged at the front side of the casing 1. The panel 12 is the main appearance surface of the wall-mounted air conditioner 10000 and can shield the casing 1 and the components in the accommodation cavity V1.

[0117] The wall-mounted air conditioner 10000 further includes a second motor 5, which is located at one end of the main body 1000 in the length direction, in combination with Figures 5-6 、 Figure 9 、 Figure 11 、 Figures 18-20 , the second motor 5 is arranged in the accommodation cavity V1, and the second motor 5 is located at the left end of the main body 1000 in the length direction. In this way, the first motor and the second motor 5 are located at both ends of the heat exchange fan 41 in the length direction, on the one hand, the two motors are separated and far away from each other, and the electromagnetic interference between them is small, and on the other hand, the two motors are arranged at both ends of the heat exchange fan 41 in the length direction, rather than arranged 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 shape and is thin and light.

[0118] Referring to Figure 9 、 Figure 11 、 Figures 18-20 , the second motor 5 is an inner rotor motor, and the second motor 5 includes an output shaft 54.

[0119] The second motor 5 further includes a stator portion 51 and a rotor portion 52, and the stator portion 51 is arranged around the outside of the rotor portion 52 in the radial direction of the rotor portion 52.

[0120] The stator part 51 and the rotor part 52 are main parts of the second motor 5, and the output shaft 54 is fixedly connected with the rotor part 52. The stator part 51 has a coil wound thereon, and the coil generates an alternating magnetic field after being supplied with alternating current, and the rotor part 52 generates an induction in the alternating magnetic field and rotates.

[0121] For example, the rotor part 52 can be a magnetic ring or a magnetic tile. For example, the rotor part 52 is a magnetic ring, so that the magnetic flux leakage loss can be reduced, the magnetic flux can be enhanced, and the power output efficiency of the second motor 5 can be improved. Moreover, when the magnetic ring is adopted, the magnetic field distribution is uniform, the anti-interference performance is good, and the mechanical precision is higher.

[0122] Referring to Figures 18-20 As shown in the figure, the second motor 5 further includes a motor shell 53, which can support and protect the main parts of the second motor 5. The motor shell 53 is fixedly connected with the stator part 51, so that the stator part 51 can be installed through the motor shell 53, and the second motor 5 is convenient to be fixed.

[0123] 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 rotor part 52.

[0124] Referring to Figures 9-16 As shown in the figure, the wall-mounted air conditioner 10000 further includes a fresh air fan 6, which is a diagonal flow fan, and the fresh air fan 6 is connected with the output shaft 54 of the second motor 5. The output shaft 54 can drive the fresh air fan 6 to rotate synchronously when the output shaft 54 rotates.

[0125] The airflow direction of the diagonal flow fan forms a certain angle (non-0 angle) with the impeller axis, and the air enters along the axial direction from the inlet, but the exhaust direction is along the diagonal line direction of the axial direction and the vertical axis, so that the air volume and air pressure characteristics of the diagonal flow fan are between those of the axial flow fan and the centrifugal fan, which can provide higher air volume and certain air pressure capacity. The noise of the diagonal flow fan is low when it rotates, and the diagonal flow fan has better noise reduction effect than the axial flow fan. The diagonal flow fan adopts optimized blade design and fluid dynamics principle, improves the ventilation efficiency, and reduces the energy consumption. In addition, the diagonal flow fan has compact appearance design, small size and light weight, and is convenient to install and maintain.

[0126] When the diagonal flow fan rotates, the airflow simultaneously performs radial and lateral mixing flow through the work of the diagonal flow fan, reduces airflow separation and turbulence, and thus reduces aerodynamic noise.

[0127] Referring to Figures 5-11As shown, the wall-mounted air conditioner 10000 further comprises a fresh air shell 8, a fresh air duct V01 is formed in the fresh air shell 8, the fresh air fan 6 is installed in the fresh air shell 8, and a fresh air inlet 801 and a fresh air outlet 802 are formed on the fresh air shell 8. The fresh air inlet 801 and the fresh air outlet 802 are both in communication with the fresh air duct V01, and 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.

[0128] The rotation of the fresh air fan 6 can make outdoor air enter the fresh air shell 8 from the fresh air inlet 801, and can make the outdoor air entering the fresh air shell 8 enter the indoor space from the fresh air outlet 802. The rotation of the fresh air fan 6 provides driving force for the airflow.

[0129] In some embodiments, the fresh air shell 8 and the fresh air fan 6 are constructed as a fresh air device. The fresh air fan 6 is arranged in the fresh air duct V01 and is used to drive the airflow to be sucked in from the fresh air inlet 801 and discharged to the indoor space through the fresh air outlet 802. The operation of the fresh air fan 6 provides the driving force for the fresh air flow.

[0130] Therefore, by arranging the fresh air duct V01 and the fresh air fan 6, when the air in the room is relatively dirty or the air quality is poor, the relatively fresh outdoor air can be driven by the fresh air fan 6 to enter the indoor environment, so as to improve the airflow environment in the room. The fresh air device can provide fresh air for the room.

[0131] At least one of the fresh air inlet 801 or the fresh air outlet 802 can be provided with a valve, and by opening or closing the valve, the opening or closing of the fresh air duct V01 can be realized. By opening the fresh air duct V01, the fresh air mode can be started; by closing the fresh air duct V01, the fresh air mode can be closed.

[0132] In this application, the fresh air device of the wall-mounted air conditioner 10000 at least comprises the fresh air fan 6, the second motor 5 and the fresh air shell 8. Instead of using a centrifugal fan, the fresh air device uses a mixed flow fan structure, and the traditional volute structure is cancelled.

[0133] In the mixed flow fan of the fresh air device, after the gas is sucked into the fresh air duct V01 and enters the fresh air fan 6, it rotates along the fresh air blade 62 of the fresh air fan 6, and wind pressure is generated by the constraint and guidance of the fresh air shell 8.

[0134] The mixed flow fan is not like the centrifugal fan in which air is axially sucked in and radially thrown out, but obtains a path of axial entry and axial exit, so the impact on the fresh air blade 62 and the fresh air shell 8 is smaller, not only the power consumption is reduced, but also the noise is reduced. The flow coefficient of the mixed flow fan is larger than that of the centrifugal fan, and the air volume obtained is larger than that of the centrifugal fan.

[0135] Referring toFigures 1-3 、 Figure 9 As shown in FIG. 12, the panel 12 is provided with a panel air outlet 121, and the fresh air outlet 802 is in communication with the panel air outlet 121. The outdoor air in the fresh air casing 8 can be blown out from the fresh air outlet 802 and the panel air outlet 121 to the front side, so that the outdoor air entering the fresh air casing 8 is discharged from the front side of the main body 1000. In this way, the fresh air blown out from the panel air outlet 121 can directly blow on the user or give the user a top-to-bottom showering air experience, and the user experience is better.

[0136] The panel 12 directly faces the user, and the panel air outlet 121 is a visual air outlet. By increasing the diameter of the panel air outlet 121, the air volume discharged from the panel air outlet 121 per unit time can be increased. Fresh air visualization can increase the user's understanding of the fresh air device and can be appreciated from the sense of touch.

[0137] In some embodiments, the fresh air outlet 802 can also be designed with a large diameter, so that when the air volume is constant, the air speed can be appropriately reduced, thereby reducing the discomfort when the air is directly blown on the user.

[0138] In some embodiments, a mesh cover can also be provided on the panel 12, which covers the panel air outlet 121 to prevent dust and debris from the outside from falling into the fresh air outlet 802 through the panel air outlet 121. The mesh cover has mesh holes that are in communication with the panel air outlet 121 and the space outside the panel 12, so that the air at the panel air outlet 121 can be blown to the indoor space through the mesh holes.

[0139] In the present application, since the fresh air fan 6 is a mixed flow fan, the discharged air performs both centrifugal and axial motion, that is, the motion of the air discharged from the fresh air outlet 802 to the indoor space is a combination of axial flow and centrifugal motion. The axial motion of the air is beneficial to sending the air farther, and the centrifugal motion of the air is beneficial to the diffusion of the air around the fresh air outlet 802 after being discharged, thereby expanding the air supply area. Therefore, when the panel air outlet 121 is provided on the panel 12, part of the fresh air is blown to the front side of the air conditioner and diffused far away, and part of the fresh air is diffused under the centrifugal action, so that the fresh air can be distributed to more areas.

[0140] Specifically, the part of the fresh air device provided with the mixed flow fan is in a cylindrical shape, which is compact in structure and occupies relatively small space.

[0141] According to the wall-mounted air conditioner 10000 of the embodiments of the present application, by communicating the fresh air outlet 802 with the panel air outlet 121, air can be discharged from the front side of the panel 12, and the user can directly feel the fresh air, which is beneficial to improving the user experience.

[0142] In some embodiments of the present application, with reference to Figures 9-16As shown, the fresh air fan 6 includes a fresh air hub 61 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.

[0143] The fresh air fan 6 also includes a fan outer cylinder 63, which is arranged radially outside the fresh air hub 61. The fan outer cylinder 63 and the fresh air hub 61 form a first airflow channel 64 therebetween. 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 is connected 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. The 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 flow to the fresh air outlet 802 from the first airflow outlet 642, and then flow to the panel air outlet 121, and finally flow into the indoor space through the panel air outlet 121.

[0144] Specifically, in the front-rear 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 is the first airflow outlet 642.

[0145] The fresh air fan 6 also includes a fresh air blade 62, which is located in the first airflow channel 64 and connects the fresh air hub 61 and the fan outer cylinder 63. When the fresh air fan 6 rotates, the fresh air blade 62 pushes the airflow, which can accelerate the airflow and increase the air volume passing through the fresh air blade 62, which is conducive to increasing the amount of fresh air provided by the fresh air device to the indoor space.

[0146] The first airflow channel 64 between the fresh air hub 61 and the fan outer cylinder 63 forms a ring-shaped channel that can constrain and guide the airflow to flow in a ring direction. In this way, when the fresh air blade 62 drives the airflow to move axially, it can drive the airflow to move centrifugally. The centrifugally moving airflow is constrained by the fresh air hub 61 and the fan outer cylinder 63, which can increase the air pressure of the airflow and form a driving force to blow the airflow.

[0147] The fan outer cylinder 63 provides a stable channel for the airflow and guides the airflow to flow in the designed direction, so that the air moves both centrifugally and axially inside the fresh air fan 6, achieving oblique flow. The fan outer cylinder 63 can surround the fresh air hub 61 and the fresh air blade 62 to form a relatively closed space, effectively preventing the airflow from leaking out from the periphery of the diagonal flow fan, reducing airflow loss, increasing pressure and air volume output, and enabling the fresh air fan 6 to more effectively deliver the gas to the desired location.

[0148] The new air hub 61 also provides a stable passage for the airflow, guiding the airflow to flow in the designed direction. This makes the airflow pass through the new air fan 6 more smoothly, reduces the generation of airflow turbulence and vortex, helps to improve the efficiency and performance of the new air fan 6, and makes the air do both centrifugal and axial motion to realize oblique flow.

[0149] The new air hub 61, the fan outer barrel 63 and the new air blade 62 cooperate with each other to change the speed and direction of the airflow, convert the kinetic energy of the airflow into static pressure energy, thereby increasing the static pressure at the new air outlet 802, enhancing the air supply capacity of the new air fan 6, and enabling the new air fan 6 to deliver air to a farther distance or overcome greater resistance.

[0150] Referring to Figures 12-15 , the new air hub 61 is provided with a mounting hole 6113, and the output shaft 54 penetrates the mounting hole 6113.

[0151] Referring to Figure 12 , the new air hub 61 includes a hub body part 611, and the mounting hole 6113 is arranged on the hub body part 611, so that the hub body part 611 is connected with the output shaft 54.

[0152] Referring to Figure 12 , the new air hub 61 further includes a hub flared part 612, and the hub flared part 612 is connected to the outer side of the hub body part 611, and the new air blade 62 is arranged on the hub flared part 612.

[0153] The hub flared part 612 is conical, and the small-diameter end of the hub flared part 612 faces the new air inlet 801, and the large-diameter end faces the new air outlet 802. The hub flared part 612 forms an accommodation space inside to accommodate at least part of the structure of the second motor 5. For example, the accommodation space is used to accommodate at least part of the structure of the output shaft 54.

[0154] The hub body part 611 includes a base plate 6111 and a mounting sleeve 6112, the mounting sleeve 6112 is connected with the base plate 6111, the mounting hole 6113 is arranged on the mounting sleeve 6112, and the output shaft 54 penetrates into the mounting hole 6113.

[0155] The output shaft 54 is screwed with the nut after penetrating through the mounting hole 6113. As shown in Figure 9 , Figures 18-20 , the output shaft 54 penetrates through the mounting hole 6113, and the output shaft 54 is provided with an external thread section 541. After the output shaft 54 penetrates through the mounting hole 6113, the external thread section 541 is screwed with the nut to cooperate, thereby better connecting and fixing the output shaft 54 with the new air fan 6, preventing the output shaft 54 from being separated from the new air fan 6. Wherein, in the front-rear direction of the wall-mounted air conditioner 10000, the nut is located at the rear end of the new air fan 6.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] The air outlet flow guide 7 can regulate the airflow leaving the fresh air fan 6, making the airflow more smoothly discharged, reducing the turbulence and vortex of the airflow, improving the outlet pressure and efficiency of the fresh air fan 6, and also helping to reduce noise.

[0164] In some embodiments of the present application, the air outlet flow guide 7 includes a flow guide inner cylinder 71, a flow guide outer cylinder 73, and flow guide vanes 72. In the radial direction of the air outlet flow guide 7, the flow guide outer cylinder 73 is arranged outside the flow guide inner cylinder 71, a second airflow passage 74 is formed between the flow guide inner cylinder 71 and the flow guide outer cylinder 73, the flow guide vanes 72 are located in the second airflow passage 74, and the flow guide vanes 72 connect the flow guide inner cylinder 71 and the flow guide outer cylinder 73, so that the flow guide inner cylinder 71 and the flow guide outer cylinder 73 are connected. The arrangement of the flow guide vanes 72 can increase the division of the second airflow passage 74 into multiple small passages, and the airflow is divided into multiple blowing streams, thereby improving the perceived comfort of the user when the fresh air is blown out, and avoiding the discomfort caused to the user when a whole stream of airflow is directly blown out without being divided into multiple streams.

[0165] The front end of the second airflow passage 74 is arranged towards the panel air outlet 121, and the rear end of the second airflow passage 74 is arranged towards 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, pass through the first airflow passage 64, the fresh air outlet 802, and the second airflow passage 74 in sequence, and then be blown out forward through the panel air outlet 121. In this way, the fresh air fan 6 and the air outlet flow guide 7 can be arranged compactly, the air outlet path is shortened, and the air resistance is small.

[0166] The flow guide vanes 72 are arranged to comb and guide the turbulent airflow, so that the airflow flows in a designed direction and path, becomes more smooth and stable, and the vortex and turbulence of the airflow are reduced. The flow guide inner cylinder 71 and the flow guide outer cylinder 73 function to form a ring-shaped second airflow passage 74, providing a stable passage for the airflow and guiding the airflow to flow in a designed direction.

[0167] In this way, through the regulating effect on the airflow, the airflow enters the indoor environment in a more ideal state, reducing the energy loss of the airflow in the flow process, thereby improving the overall efficiency of the diagonal flow fan.

[0168] The air outlet flow guide 7 usually includes a plurality of flow guide vanes 72, which are uniformly distributed around the circumferential direction of the first airflow outlet 642 of the fresh air fan 6. This uniform distribution can uniformly guide and regulate the airflow on the entire outlet cross section, avoiding the occurrence of airflow deflection or local turbulence.

[0169] In some embodiments of the present application, with reference to Figures 7-11As 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.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] Optionally, the spacing d1 between adjacent guide vanes 72 can be 10mm-20mm, depending on the diameter ratio. (See reference here.) Figure 7 A 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.

[0174] 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.

[0175] In some embodiments of this application, reference is made toFigure 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 air flow, increase the speed of the air, and increase the air volume. The spiral blade has good wind pressure capacity.

[0176] The fresh air blade 62 is designed in a wing shape and is configured as a spiral blade structure, so that the fresh air blade 62 can better adapt to the air flow and reduce the noise generated by the air flow impacting the fresh air blade 62.

[0177] In some embodiments of the present application, the stator part 51 of the second motor 5 is connected to the air outlet flow guide 7. The stator part 51 and the air outlet flow guide 7 can be directly connected or indirectly connected, and the stator part 51 is fixed relative to the air outlet flow guide 7.

[0178] It can be understood that the air outlet flow guide 7 is installed on the fresh air shell 8, the fresh air shell 8 is installed on the base, and the second motor 5 is installed on the air outlet flow guide 7, which is equivalent to being indirectly installed on the base. Therefore, the stability of the second motor 5 can be ensured, and the shaking can be reduced.

[0179] In addition, the air outlet flow 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 area, and the second motor 5 is installed on the air outlet flow guide 7 at this time. The second motor 5 can be arranged in the windless area of the fresh air fan 6. On the one hand, the second motor 5 does not need to be installed at the air inlet end of the fresh air fan 6, avoiding the second motor 5 from becoming an air inlet obstacle. On the other hand, the installation in the windless area allows the second motor 5 to be arranged close to the fresh air fan 6, avoiding the formation of a large bending moment and reducing the shaking of the fresh air fan 6, thereby reducing the operation noise of the fresh air fan 6.

[0180] In some embodiments of the present application, referring to Figure 9 , Figure 11 As shown, the wall-mounted air conditioner 10000 further comprises a motor support 91, the motor support 91 is located on the radially inner side of the flow guide inner cylinder 71, and the motor support 91 is connected to the air outlet flow guide 7. The motor support 91 is used to install the second motor 5.

[0181] As shown in Figure 9 , Figure 11 The stator part 51 of the second motor 5 is installed on the side of the motor support 91 away from the fresh air hub 61. It can be understood that when an inner rotor motor is used, the installation position on the stator part 51 is limited, so the stator part 51 is installed on the side of the motor support 91 away from the fresh air hub 61, so that the motor support 91 can hold the stator part 51, thereby supporting the entire second motor 5. Moreover, the axial distance between the installation fixed point position of the second motor 5 and the connection position of the fresh air fan 6 is short, which is conducive to reducing the rotating bending moment and improving the stability.

[0182] In some embodiments, as shown in Figure 9 , Figure 11 The air outlet flow guide 7 can further include a support plate 76 connected to the radially inner side of the flow guide inner cylinder 71, and the stator portion 51 of the second motor 5 is clamped between the motor support 91 and the support plate 76. In this way, the axial ends of the stator portion 51 are fixed, further improving the installation stability of the second motor 5 and reducing the shaking generated during operation.

[0183] Specifically, as shown in Figure 21 The motor support 91 can include an inner ring plate 911 and at least two connection limb plates 912 spaced apart and connected to the inner ring plate 911 in the circumferential direction, and the connection limb plates 912 are connected to the flow guide inner cylinder 71 or the support plate 76. In this way, the inner ring plate 911 can be used to fix the stator portion 51 in one full circle in the circumferential direction, and the connection of the connection limb plates 912 allows the size of the inner ring plate 911 to be reduced, thereby reducing the weight. The stator portion 51 is fixed to the air outlet flow guide 7 by the motor support 91, and the stator portion 51 does not need to be punched, and the structure of the second motor 5 does not need to be damaged.

[0184] In some embodiments of the present application, referring to Figures 9-11 The fresh air hub 61 is a cylindrical body, specifically a conical cylindrical body, and the fresh air hub 61 is open at one end facing the panel air outlet 121. The inside of the fresh air hub 61 forms a receiving space, and at least part of the output shaft 54 is located in the fresh air hub 61, so that the output shaft 54 does not need to be too long, and the bending moment generated during rotation can be relatively small, thereby improving the dynamic stability of the fresh air fan 6.

[0185] In some embodiments of the present application, referring to Figure 9 , Figure 17 The air outlet flow guide 7 further includes a reinforcing ring 75 connected to the flow guide inner cylinder 71, and at least part of the stator portion 51, the rotor portion 52, and the motor housing 53 are located in the reinforcing ring 75. For example, at least part of one of the stator portion 51, the rotor portion 52, and the motor housing 53 can be located in the reinforcing ring 75, at least part of two of the stator portion 51, the rotor portion 52, and the motor housing 53 can be located in the reinforcing ring 75, or at least part of the stator portion 51, at least part of the rotor portion 52, and at least part of the motor housing 53 can be located in the reinforcing ring 75. In this way, the second motor 5 can occupy the space in the reinforcing ring 75, reducing the axial size of the fresh air device, and making the front-to-back direction of the wall-mounted air conditioner 10000 more compact.

[0186] It should be noted that when the structure of the fresh air device is described, the "axial direction", "radial direction" and "circumferential direction" are all based on the axial direction, radial direction and circumferential direction 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.

[0187] In some embodiments of the present application, referring to FIG. 6, the reinforcing ring 75 is located outside the fresh air hub 61, and the end of the reinforcing ring 75 is arranged opposite to the end of the fresh air hub 61. Figure 9

[0188] In combination with FIGS. 6 and 7, Figure 9 , Figure 12 , Figure 17 the outer circumferential surface of the reinforcing ring 75 is a flow guide surface 751, and the outer circumferential surface of the hub flared portion 612 and the flow guide surface 751 form an almost continuous and smooth flow guide structure. When the airflow flows from the first airflow channel 64 to the second airflow channel 74, the airflow can sequentially flow through the outer circumferential surface of the hub flared portion 612 and the flow guide surface 751, thereby preventing the airflow path from suddenly changing.

[0189] In some embodiments of the present application, referring to FIG. 6, the fresh air fan 6, the fresh air hub 61 and the fresh air blade 62 are an integral injection molding part, the fan outer cylinder 63 is a separate part, and the fan outer cylinder 63 is fixedly connected to the fresh air blade 62. Therefore, the processing and manufacturing difficulty of the fresh air fan 6 can be simplified. Figure 16 It can be understood that the fresh air hub 61 is connected to the second motor 5 and is the power connection source of the fresh air fan 6. The fresh air blade 62 is used to drive the airflow to flow and is the power consumption part of the fresh air fan 6, which bears the largest torque. At this time, the fresh air hub 61 and the fresh air blade 62 are integrally injection molded to maximize the risk of separation. The fan outer cylinder 63 is arranged as a separate part and is separately processed, which can reduce the processing difficulty of the fresh air fan 6 and reduce the scrap rate.

[0190] In some embodiments of the present application, referring to FIG. 6, the inner wall of the fan outer cylinder 63 is provided with a clamping hole 631, and the blade edge of the fresh air blade 62 is provided with a clamping block 621, and the clamping block 621 is inserted into the clamping hole 631. The fresh air blade 62 is clamped and fixed with the fan outer cylinder 63, which is convenient and fast to operate and is beneficial to saving the processing and manufacturing time of the fresh air fan 6. The number of clamping blocks 621 on each fresh air blade 62 can be one or more, and the clamping hole 631 corresponds to the clamping block 621 one by one. When the number of clamping blocks 621 on each fresh air blade 62 is more than one, the lengths of the plurality of clamping blocks 621 can be equal or not equal. For example, in

[0191] Figure 16 It can be understood that the fresh air hub 61 is connected to the second motor 5 and is the power connection source of the fresh air fan 6. The fresh air blade 62 is used to drive the airflow to flow and is the power consumption part of the fresh air fan 6, which bears the largest torque. At this time, the fresh air hub 61 and the fresh air blade 62 are integrally injection molded to maximize the risk of separation. The fan outer cylinder 63 is arranged as a separate part and is separately processed, which can reduce the processing difficulty of the fresh air fan 6 and reduce the scrap rate. Figure 16 ​​In some embodiments, the number of clamping blocks 621 on each fresh air blade 62 is two, and the lengths of the two clamping blocks 621 are not equal.

[0192] During assembly, the fresh air blade 62 connected to the fresh air hub 61 can be squeezed into the fan outer cylinder 63 using an assembly tool, at which time the fan outer cylinder 63 is slightly deformed. When the blocks 621 are inserted into the clamping holes 631, the fan outer cylinder 63 returns to its original shape and clamps the fresh air blade 62.

[0193] Of course, the structure of the fresh air fan 6 can also not be limited to this, and the structure of an inclined flow fan known in the prior art can also be used.

[0194] Specifically, the fresh air fan 6 can be a plastic part, thereby being 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.

[0195] Specifically, the fresh air shell 8 can be a plastic part, thereby being light in weight and low in cost. In some embodiments, the fresh air shell 8 can also be a resin part, a metal part, etc.

[0196] In some embodiments of the present application, with reference to Figures 9-10 As shown in the drawings, the fresh air fan 6 includes a first wind-blocking ring 65, which is arranged outside the fan outer cylinder 63 in the radial direction of the fresh air hub 61, and the first wind-blocking ring 65 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 is arranged in the direction of the first air inlet 641. The first wind-blocking ring 65 can block the airflow when the airflow flows outside the fan outer cylinder 63, thereby reducing the noise of the airflow. The airflow can be temporarily stopped in the first wind-blocking groove 66, thereby further achieving the effect of reducing noise.

[0197] In addition, the arrangement of the first wind-blocking groove 66 can effectively prevent the airflow from flowing to the periphery of the fresh air fan 6, effectively prevent the high-pressure area of the fresh air fan 6 from leaking to the low-pressure area, reduce the leakage amount of the airflow, and improve the efficiency and performance of the fresh air fan 6. When the airflow attempts to flow to the periphery of the fresh air fan 6, the airflow will be blocked in the first wind-blocking groove 66, thereby increasing the flow resistance and reducing the possibility of leakage.

[0198] Optionally, the number of first wind-blocking rings 65 can be one or two or more, and such a plurality of blocking arrangements further increase the flow resistance and further reduce the possibility of leakage. In addition, when the airflow passes through a plurality of first wind-blocking grooves 66, the airflow will be divided into a plurality of small airflows, and these small airflows will collide and rub with each other in the channel, so that the energy of the airflow is consumed and attenuated to a certain extent, thereby reducing the noise generated by the airflow.

[0199] In some embodiments of the present application, the fresh air shell 8 comprises a second air blocking ring 83, which is arranged on the inner wall of the fresh air duct V01 and surrounds the outer side of the fan outer cylinder 63, and at least part of the second air blocking ring 83 is located in the first air blocking groove 66. Thus, the second air blocking ring 83 and the first air blocking ring 65 form a multi-layer labyrinth structure, and the second air blocking ring 83 and the first air blocking ring 65 can block the airflow in multiple stages when the airflow flows through the outer side of the fan outer cylinder 63, thereby reducing the gap between the outdoor fresh air and the fresh air fan 6 and the fresh air shell 8, reducing the aerodynamic noise, and further achieving the effect of reducing noise.

[0200] The labyrinth structure formed by the first air blocking ring 65 and the second air blocking ring 83 is composed of a plurality of annular channels that intersect with each other, further increasing the tortuosity of the peripheral airflow channel of the fresh air fan 6. This constantly changes direction in the tortuous channel, further increasing the flow resistance and thereby reducing the likelihood of leakage.

[0201] In some embodiments of the present 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. Thus, the first airflow channel 64 has a clear bunching effect on the airflow, which is not easy to spread out, so that the wind speed at the first airflow outlet 642 is greater than that at the first airflow inlet 641, and the airflow is blown out of the fresh air outlet 802 at a relatively high speed, which is conducive to improving the user's experience of the fresh air wind.

[0202] The air outlet guide 7 guides the high-speed rotating airflow accelerated by the diagonal flow fan in the flow channel to the panel 12 direction, optimizes the airflow characteristics, and makes the airflow direction more concentrated, continuous and stable.

[0203] The airflow discharged by the fresh air device is in the form of high-speed spiral diffusion. Based on the diagonal flow fan, a larger air volume and wind speed can be generated, and the large exhaust area of the air outlet is conducive to airflow diffusion, easy to mix with indoor air to form more uniform airflow distribution, improve the ventilation effect in the home environment and reduce noise.

[0204] By using the diagonal flow fan and the air outlet guide 7, the air outlet noise is small, the wind speed is low, and the airflow noise is small, and the environment is relatively quiet.

[0205] In some embodiments of the present application, the wall-mounted air conditioner 10000 further comprises a purification member 11, as shown in Figure 3 、 Figure 9 、 Figure 11 The purification member 11 is installed in the fresh air duct V01, and the purification member 11 is used to purify the fresh air blown into the indoor, and improve the cleanliness of the indoor air.

[0206] In some embodiments of the present application, the purifying member 11 is connected to the fresh air casing 8, so as to facilitate the assembly of the purifying member 11 and avoid interference between the purifying member 11 and the fresh air fan 6.

[0207] The purifying member 11 is located at the axial air inlet end of the fresh air fan 6. When the fresh air fan 6 rotates, outdoor air can enter the fresh air casing 8 through the fresh air inlet 801, and the outdoor air entering the fresh air casing 8 can be blown through the purifying member 11 and then enter the indoor space through the fresh air outlet 802 and the panel air outlet 121, thereby improving the cleanliness of the indoor air.

[0208] In some embodiments of the present application, the purifying member 11 is vertically arranged and located behind the fresh air fan 6. In this way, the fresh air flow can almost vertically blow through the purifying member 11, and the fresh air inlet consumption can be further reduced, thereby increasing the fresh air flow. Moreover, when the indoor heat exchanger 2 is in a refrigeration state and condensate water is generated in the fresh air, the condensate water can be left on the purifying member 11 when the air flows through the purifying member 11, thereby further avoiding the blowing of water when the fresh air device blows air.

[0209] For example, the purifying member 11 includes a filter screen 111, as shown in Figure 3 As shown in the schematic view of the filter screen 111 being detached from the fresh air casing 8, when the filter screen 111 is installed in the fresh air casing 8, the filter screen 111 covers the entire air inlet end of the fresh air fan 6. The filter screen 111 has a large coverage area and a large filtering area, and has a good filtering effect. The arrangement of the filter screen 111 helps to ensure sufficient contact area with the airflow, and the filter screen 111 has a light weight and a low airflow noise. For example, the filter screen 111 is a Hepa screen, and thus has a strong adsorption force and a strong filtering effect on dust in the air.

[0210] For example, the filter screen 111 is in a plate shape, so that the filter screen 111 is relatively thin as a whole, which is conducive to saving the axial dimension of the fresh air device.

[0211] For example, the filter screen 111 is in a square shape, so that the filter screen 111 is convenient to position and install, and is not easy to shake after being fixed. Moreover, the filter screen 111 is easy to process and has little waste.

[0212] In some embodiments, the filter screen 111 is in a square shape, so that the filter screen 111 is convenient to position and install, and is not easy to shake after being fixed. Moreover, the filter screen 111 is easy to process and has little waste. The filter screen 111 covers the first airflow inlet 641 of the fresh air fan 6, and the side length of the filter screen 111 is greater than the diameter of the first airflow inlet 641. In this way, all the fresh air flowing into the first airflow passage 64 can flow through the filter screen 111 in advance, and the filtering cleanliness is high.

[0213] In some embodiments of the present application, the fresh air shell 8 is provided with a first mounting port 803, and the purification component 11 is detachably assembled in the fresh air shell 8 through the first mounting port 803. In this way, when the purification component 11 is damaged or saturated, the purification component 11 can be disassembled for maintenance or replacement.

[0214] In some embodiments of the present application, as shown in Figures 3-4 the bottom of the cabinet 1 is provided with a second mounting port 106, which is opposite to the first mounting port 803. The purification component 11 is detachably assembled in the cabinet 1 through the second mounting port 106. The purification component 11 is installed inside the fresh air shell 8 along the radial direction of the second motor 5.

[0215] In the related art, the fresh air conditioner is limited by the centrifugal volute structure form, and the purification component is perpendicular to the base. When replacing the fresh air filter screen of the purification component, the panel needs to be opened, the filter screen support is taken out, the old filter screen is replaced with a new one, and then the filter screen support is installed back and the panel is closed. Due to the complex filter screen replacement operation, some fresh air users do not replace the fresh air filter screen in time, and the fresh air effect is not good. The wall-mounted air conditioner 10000 of the present application can directly assemble and disassemble the purification component 11 from the bottom of the cabinet 1 to replace the filter screen without opening the panel 12, thereby improving the convenience when replacing or maintaining the purification component 11.

[0216] The wall-mounted air conditioner 10000 of the present application adopts a brand-new architecture form. The purification component 11 is installed inside the fresh air shell 8 along the radial direction of the second motor 5, and the diagonal flow fan is installed in front 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 without opening the panel 12. The purification component 11 can be extracted from the second mounting port 106 to replace the filter screen. The filter screen replacement time is shortened from 3 minutes to 20 seconds, and the maintenance efficiency is improved by 15 times.

[0217] In some embodiments of the present application, as shown in Figures 1-4 the front of the cabinet 1 is provided with a cabinet air outlet 105. The fresh air air outlet 802, the cabinet air outlet 105 and the panel air outlet 121 are connected to communicate with each other to air out forward through the cabinet air outlet 105 and the panel air outlet 121. In a plane perpendicular to the front-rear direction of the wall-mounted air conditioner 10000, the inner circumferential walls of the fresh air air outlet 802, the cabinet air outlet 105 and the panel air outlet 121 at least partially overlap on the plane. Thus, the air can be smoothly air out forward.

[0218] The panel 12 can be opened or closed. When the panel 12 is opened, the cabinet air outlet 105 can be exposed.

[0219] In some embodiments, the panel 12 can be disassembled from the cabinet 1 by disassembly to open the panel 12.

[0220] In some embodiments, the panel 12 is connected to the cabinet 1 by a hinge, and the panel 12 can be opened by rotating the panel 12 upward.

[0221] In some embodiments, the panel 12 is connected to the cabinet 1 by a hinge, and the panel 12 can be opened by rotating the panel 12 upward.

[0222] In some embodiments of the present application, the fresh air housing 8 comprises a first housing part 81, the front of the first housing part 81 is open, and the bottom of the first housing part 81 is provided with a fresh air inlet 801.

[0223] The cavity formed by the first housing part 81 is located at the air inlet end of the fresh air fan 6, and can be used to accommodate air, so that the air can enter the fresh air fan 6 vertically along the axial direction from the first housing part 81, thereby improving the air suction efficiency of the fresh air fan 6 and reducing the air suction loss.

[0224] When the wall-mounted air conditioner 10000 comprises the purification member 11, the purification member 11 is installed in the first housing part 81. In this way, the installation is separated, which is convenient for assembly.

[0225] The fresh air housing 8 further comprises a wind pipe joint 84, the bottom of the first housing part 81 is provided with a transition port 811, and the wind pipe joint 84 is connected to the transition port 811. The air inlet of the wind pipe joint 84 can be formed as the fresh air inlet 801.

[0226] In some embodiments, the wall-mounted air conditioner 10000 can comprise a fresh air inlet pipe (not shown in the figure) connected to the wind pipe joint 84, and the side wall (for example, the right side wall or the left side wall) of the cabinet 1 is provided with an inlet pipe avoiding port (not shown in the figure). After the fresh air inlet pipe is connected to the fresh air inlet 801 from the bottom of the main body 1000, it is bent and extends horizontally, and then extends out of the inlet pipe avoiding port on the side wall of the cabinet 1, and then extends to the outside.

[0227] In some embodiments, the fresh air inlet 801 is located at the bottom of the main body 1000 and close to the rear side, so that after the fresh air inlet pipe is connected to the fresh air inlet 801, the fresh air inlet pipe can be arranged close to the wall.

[0228] It can be understood that the main body 1000 usually further comprises a refrigerant pipe and a drain pipe at one end in the length direction. The refrigerant pipe is used to connect the indoor heat exchanger 2 with the compressor and the outdoor heat exchanger, and the drain pipe is used to drain the condensate water generated in the wall-mounted air conditioner 10000.

[0229] The guide pipe avoiding opening is arranged on the side wall of the casing 1, and then the fresh air guide pipe is transversely arranged and then led out, so that at least one of the fresh air guide pipes is arranged together with the drain pipe and the refrigerant pipe. In this way, the plurality of pipes are covered by the outer beam pipe or the beam belt, so that the plurality of pipes have the same appearance, and the number of the pipes on the wall-mounted air conditioner 10000 is reduced after installation, and the appearance is simple, which facilitates assembly and avoids the risk of collision of the plurality of pipes.

[0230] The fresh air casing 8 further comprises a second casing portion 82 connected to the front of the first casing portion 81, the fresh air fan 6 is located in the second casing portion 82, the front of the second casing portion 82 is open to form a fresh air outlet 802, and the fresh air outlet 802 is arranged opposite to the panel air outlet 121.

By arranging the first casing portion 81 as a two-half-casing structure, the processing and manufacturing of the first casing portion 81 can be facilitated.

[0232] For example, the first half casing 812 and the second half casing 813 are detachably connected. The detachable connection facilitates assembly and subsequent adjustment and maintenance.

[0233] In some embodiments of the present application, as shown in Figures 9-11 The second casing portion 82 comprises a third half casing 821 and a fourth half casing 822, the third half casing 821 is located at the rear side of the fourth half casing 822, the third half casing 821 is connected to the second half casing 813, the third half casing 821 is connected to the fourth half casing 822, and the fourth half casing 822 is connected to the air outlet flow guide 7. By arranging the second casing portion 82 as a two-half-casing structure, the processing and manufacturing of the second casing portion 82 can be facilitated.

[0234] For example, the third half casing 821 and the second half casing 813 are detachably connected, the third half casing 821 and the fourth half casing 822 are detachably connected, and the fourth half casing 822 and the air outlet flow guide 7 are detachably connected.

The guide vane 13 can rotate relative to the casing 1. When the guide vane 13 is rotated to an open state, the heat exchange air outlet 102 is exposed, facilitating air outlet from the heat exchange air outlet 102. When the guide vane 13 is rotated to a closed state, the heat exchange air outlet 102 is shielded, preventing sundries, flying insects and the like from entering the interior of the wall-mounted air conditioner 10000 through the heat exchange air outlet 102 when the wall-mounted air conditioner 10000 is not working.
