[0077] Some embodiments of the present utility model provide a wall-mounted air conditioner.

[0078] 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.

[0079] 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.

[0080] The compressor is configured to compress the refrigerant to form high-pressure refrigerant from low-pressure refrigerant.

[0081] 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 releases heat to the outdoor air through the outdoor heat exchanger to condense. The outdoor heat exchanger works as an evaporator in the heating mode of the air conditioner, so that the refrigerant after pressure reduction absorbs the heat of the outdoor air through the outdoor heat exchanger to evaporate.

[0082] In some embodiments, the outdoor heat exchanger can include heat exchange fins to expand the contact area between the outdoor air and the refrigerant transferred in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0083] The outdoor fan is configured to suck the outdoor 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.

[0084] 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 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 to adjust the flow rate and pressure of the refrigerant flowing through the throttling device.

[0085] In some schemes, 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.

[0086] The indoor heat exchanger is configured to exchange heat between the indoor air and the refrigerant transferred 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 transferred in the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0087] The heat exchange fan is configured to suck the indoor air into the indoor unit and send the indoor air after heat exchange with the indoor heat exchanger to the indoor, and the heat exchange fan provides power for the flow of the indoor air.

[0088] 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 some control devices 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.

[0089] 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 a program stored in a non-transitory computer readable medium coupled to the control device.

[0090] The non-transitory computer readable storage medium can include a magnetic storage device (e.g., a hard disk, a floppy disk, or a tape), a smart card, or a flash memory device (e.g., an erasable programmable read-only memory (EPROM), a card, a stick, or a key drive).

[0091] At present, most 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. After the user turns on the air conditioner for a long time, if he feels that the indoor air is relatively dirty and stuffy, he needs to open the window for ventilation, which is not only troublesome to operate, 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.

[0092] Some fresh air air conditioners in the related art suck fresh air from the outside through a fresh air fan, and in this process, the outdoor air is purified by a purification element. However, since a protective net is provided between the chamber where the purification element is located and the chamber where the fresh air fan is located, it will increase the airflow resistance, and if the protective net is removed, there is a safety hazard when the user takes out or puts in the purification element.

[0093] To solve the above problems, some embodiments of the utility model provide a wall-mounted air conditioner, by setting movable shielding element at the installation port of the purification element, after taking out the purification element, the shielding element shields at least part of the installation port, prevents the user's fingers or foreign matter from extending into the volute assembly, damaged by the fresh air fan, or damage the fresh air conditioner, eliminates the safety hazard.

[0094] For example, the wall-mounted air conditioner is a kind of indoor unit. The wall-mounted air conditioner is usually installed on the wall, for example, can be installed in the upper region of indoor wall.

[0095] The following will be described in detail Figures 1-17 Detailed description of wall-mounted air conditioner 10000 according to embodiments of the present application.

[0096] Referring to Figure 1 And Figure 2According to the wall-mounted air conditioner 10000, the main body 1000 comprises a shell 1, an accommodation cavity V1 is formed in the shell 1, and a heat exchange air inlet 101 and a heat exchange air outlet 102 are formed on the shell 1. The shell 1 can play a protective role and constitute the overall appearance structure of the wall-mounted air conditioner 10000.

[0097] Generally, the shell 1 is a long strip-shaped shell body, and the length direction of the shell 1 is arranged along the horizontal direction, that is, the shell 1 is arranged on the wall along the transverse direction. In actual products, in order to discharge condensate water, the shell 1 in some embodiments is arranged on the wall along the transverse direction and forms a small angle with the horizontal plane.

[0098] Referring to Figure 3 and Figure 4 , the main body 1000 further comprises an indoor heat exchanger 2 arranged in the accommodation cavity V1. As described above, the indoor heat exchanger 2 is a loop in the refrigerant circuit, the inside of the indoor heat exchanger 2 circulates refrigerant, and is used for refrigerating or heating air circulating on the surface of the indoor heat exchanger 2. In the wall-mounted air conditioner 10000, the indoor heat exchanger 2 is generally arranged along the length direction of the shell 1.

[0099] 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.

[0100] Referring to Figures 3-5 , the main body 1000 further comprises a base 3 arranged in the accommodation cavity V1. The base 3 is a mounting and supporting structure inside the main body 1000, and the indoor heat exchanger 2 can be mounted on the base 3. For example, a volute tongue air duct V03 is formed on the base 3, and indoor air entering the shell 1 is guided in the flow direction through the volute tongue air duct V03, so that the indoor air has a small resistance when flowing through the indoor heat exchanger 2.

[0101] Referring to Figures 4-5 , the wall-mounted air conditioner 10000 further comprises a heat exchange fan 41 arranged in the volute tongue air duct V03. When the heat exchange fan 41 rotates, air can be exchanged between the inside of the air conditioner and the indoor space.

[0102] 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 uniformly distributed along the axial direction of the cross-flow fan, which is beneficial to increasing the air supply distance and the air supply range. Moreover, 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 driven air flow can flow through the entire indoor heat exchanger 2, thereby balancing the heat exchange efficiency of each position of the indoor heat exchanger 2.

[0103] By setting the heat exchange air inlet 101 and the heat exchange air outlet 102 in the casing 1, the heat exchange fan 41 can suck indoor air from the heat exchange air inlet 101 into the casing 1 when operating. After the indoor air exchanges heat with the indoor heat exchanger 2, the heat exchanged air is sent to the indoor space from the heat exchange air outlet 102.

[0104] In this way, the adjustment of the indoor environment temperature can be realized. The indoor heat exchanger 2 can act as an evaporator to provide a refrigeration air flow toward the indoor space from the heat exchange air outlet 102, or the indoor heat exchanger 2 can act as a condenser to provide a heating air flow toward the indoor space from the heat exchange air outlet 102.

[0105] 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 can be sucked from the top. 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 the 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 heat exchange air from the bottom, the blown heat exchange air is not easily blocked by the roof or 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] Referring to Figure 1 and Figure 2 , the heat exchange air inlet 101 is located above the heat exchange air outlet 102, and the heat exchange air inlet 101 can suck air from the top, so that air is not sucked from the heat exchange air outlet 102, and the heat exchange air blown from the heat exchange air outlet 102 is not directly sucked into the heat exchange air inlet 101, thereby reducing the idle circulation of the heat exchange air and avoiding the heat exchange air from participating in the indoor heat exchange process.

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

[0109] In some embodiments, the heat exchange air outlet 102 is located in front of the casing 1, i.e., 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 that when the heat exchange air outlet 102 is located in front of the casing 1, the air is blown away from the wall, and the air blowing resistance is small and the air blowing range is wide.

[0111] In some embodiments, the heat exchange air outlet 102 is located at the front side of the casing 1 and close to the bottom, for example, the heat exchange air outlet 102 is located at the front lower corner of the casing 1. In this case, the heat exchange air blown by the heat exchange air outlet 102 flows forward while flowing downward, so that the heat exchange air can be sent to a certain distance, and then the heat exchange air can sink and fall on the person or object on the ground, so that the person or object on the ground can be in the suitable indoor environment as soon as possible.

[0112] With reference to Figures 3-5 , the wall-mounted air conditioner 10000 further comprises a motor 42, the motor 42 is arranged in the accommodating cavity V1, and the motor 42 is located at one end in the length direction of the heat exchange fan 41. In this way, the installation and maintenance of the motor 42 are facilitated, and the overall height and thickness of the main body 1000 do not need to be increased due to the arrangement of the motor 42. 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.

[0113] In some embodiments, the motor 42 is an outer rotor motor. In other embodiments, the motor 42 is an inner rotor motor.

[0114] In some embodiments, the wall-mounted air conditioner 10000 can comprise a motor support, the motor support can be fixed on the base 3, and the motor support is used to fix the motor 42, so that the motor 42 can be firmly installed on the main body 1000.

[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 FIG. 1. Figures 1-3

[0116] With reference to Figure 5 , the wall-mounted air conditioner 10000 further comprises a fresh air fan 6, the fresh air fan 6 is an axial inlet and radial outlet centrifugal fan, and the fresh air fan 6 is located at the other end in the length direction of the heat exchange fan 41, i.e. the fresh air fan 6 is located on the side away from the motor 42 of the heat exchange fan 41.

[0117] The centrifugal fan itself has the characteristics of compact structure, large air volume, low noise, and the fan noise decreases obviously when the rotating speed decreases, so the fresh air fan 6 selects a centrifugal fan with a smaller size to meet the demand of large air volume. The centrifugal fan has small vibration noise and is not easy to resonate with the indoor heat exchanger 2, which is beneficial to reduce the vibration and noise of the whole wall-mounted air conditioner 10000.

[0118] With reference to Figures 6-8 ​The wall-mounted air conditioner 10000 further comprises a volute assembly 9, a fresh air duct V01 is formed in the volute assembly 9, and a fresh air inlet 801 and a fresh air outlet are formed on the volute assembly 9 and communicate with the fresh air duct V01.

[0119] The fresh air fan 6 is arranged in the fresh air duct V01, and rotation of the fresh air fan 6 can make outdoor air enter the fresh air duct V01 from the fresh air inlet 801 and make the outdoor air in the fresh air duct V01 enter the indoor environment from the fresh air outlet. The fresh air fan 6 is used to drive air flow to be sucked from the fresh air inlet 801 and discharged to the indoor environment through the fresh air outlet. The operation of the fresh air fan 6 provides power for the flow of fresh air.

[0120] Therefore, by arranging the fresh air duct V01 in cooperation with the fresh air fan 6, when the air in the indoor environment 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 air flow environment in the indoor environment.

[0121] In some embodiments, with reference to Figure 8 The fresh air duct V01 comprises a fresh air cavity V012 and a volute cavity V011 which are communicated, the fresh air fan 6 is arranged in the volute cavity V011, and the fresh air cavity V012 has a mounting port 803.

[0122] The wall-mounted air conditioner 10000 further comprises a purification component 11 which is arranged in the fresh air cavity V012 through the mounting port 803, so that the purification component 11 can be conveniently disassembled for maintenance or replacement when the purification component 11 is damaged or saturated. Rotation of the fresh air fan 6 can make outdoor air enter the fresh air cavity V012 from the fresh air inlet 801, and make the outdoor air in the fresh air cavity V012 blow through the purification component 11, then enter the volute cavity V011 and enter the indoor environment from the fresh air outlet.

[0123] For example, the purification component 11 is arranged in the fresh air cavity V012 and located at the axial air inlet end of the fresh air fan 6. The purification component 11 is connected with the volute assembly 9, so that the assembly of the purification component 11 is facilitated and interference between the purification component 11 and the fresh air fan 6 is avoided. Rotation of the fresh air fan 6 can make outdoor air enter the fresh air cavity V012 from the fresh air inlet 801, and make the outdoor air in the fresh air cavity V012 blow through the purification component 11, then enter the volute cavity V011 and enter the indoor environment from the fresh air outlet.

[0124] In this way, the fresh air flow can almost vertically blow through the purification component 11, the fresh air inlet consumption can be further reduced, and thus the fresh air flow rate is increased. 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 purification component 11 when the air flows through the purification component 11, and thus the blowing of the condensate water from the fresh air outlet is avoided.

[0125] wherein, referring to Figure 8 and Figure 9 an adjustable shielding piece 121 is arranged at the mounting port 803, for shielding at least part of the mounting port 803 after the purification piece 11 is taken out from the fresh air cavity V012.

[0126] According to the wall-mounted air conditioner 10000 of the embodiments of the present application, by arranging the adjustable shielding piece 121 at the mounting port 803 of the purification piece 11, after the purification piece 11 is taken out, the shielding piece 121 can shield at least part of the mounting port 803, preventing the user's fingers or foreign matters from extending into the volute assembly 9 and being damaged by the fresh air fan 6, or damaging the fresh air fan 6, and eliminating the safety hazard.

[0127] Referring to Figure 8 and Figure 9 and in combination with Figure 10 and Figure 11 in some embodiments of the present application, the shielding piece 121 is adjustable between a first position and a second position, in the first position, the shielding piece 121 opens the mounting port 803 and avoids the purification piece 11, in the second position, the shielding piece 121 shields at least part of the mounting port 803.

[0128] In the state that the purification piece 11 is installed in place, the shielding piece 121 is in the first position, so that the shielding piece 121 avoids the purification piece 11, after the purification piece 11 is taken out from the fresh air cavity V012, the shielding piece 121 is in the second position, so that the shielding piece 121 shields at least part of the mounting port 803.

[0129] Therefore, by limiting the shielding piece 121 to be adjustable between the first position and the second position, the activity range of the shielding piece 121 is limited, which is beneficial to the layout of the internal structure of the volute assembly 9, and makes the structure more compact.

[0130] Referring to Figure 12 and Figure 13 in some embodiments of the present application, in the second position, the gap L between the shielding piece 121 and the edge of the mounting port 803 is less than 12 mm. For example, the gap L between the shielding piece 121 and the edge of the mounting port 803 can be 1 mm, 5 mm, 8 mm, 10 mm, etc.

[0131] When the shielding piece 121 is in the second position, if the gap L between the shielding piece 121 and the edge of the mounting port 803 is too large, the user's fingers or foreign matters are easy to extend into the volute assembly 9, so as to be damaged by the fresh air fan 6, or damage the fresh air fan 6, and there is a safety hazard.

[0132] Therefore, in the above technical solution, by limiting the gap L between the shielding piece 121 and the edge of the mounting port 803 to be less than 12 mm, after the purification piece 11 is taken out, the shielding piece 121 shields at least part of the mounting port 803, more effectively preventing the user's fingers or foreign matter from extending into the volute assembly 9, avoiding being damaged by the fresh air fan 6, or damaging the fresh air fan 6, eliminating the safety hazard.

[0133] Referring to Figures 8-11 In some embodiments of the present application, the wall-mounted air conditioner 10000 further comprises an elastic piece 122 cooperating with the shielding piece 121 and the volute assembly 9, and the elastic piece 122 is adapted to drive the shielding piece 121 to move towards the second position after the purification piece 11 is taken out from the fresh air cavity V012.

[0134] When the purification piece 11 is taken out from the fresh air cavity V012, the shielding piece 121 can move towards the second position under the driving of the elastic piece 122 to shield at least part of the mounting port 803, that is, when the purification piece 11 is taken out from the fresh air cavity V012, the automatic shielding of the mounting port 803 can be achieved instantaneously.

[0135] Therefore, by providing the elastic piece 122, the shielding piece 121 can automatically shield the mounting port 803 instantaneously after the purification piece 11 is taken out from the fresh air cavity V012, the reaction is rapid, the safety is higher, the safety hazard is effectively eliminated, the user does not need to operate alone, which is beneficial to improve the user's use experience, and the structure of the elastic piece 122 is simple and the cost is low, which is beneficial to reduce the production cost of the whole machine.

[0136] Referring to Figures 8-11 In some embodiments of the present application, the shielding piece 121 can move in a translational manner between the first position and the second position. The shielding piece 121 is arranged to open and close the mounting port 803 in a translational manner, so that the shielding piece 121 does not need to swing in or out of the fresh air cavity V012 during movement, which is suitable for the narrow space inside the fresh air cavity V012, and is beneficial to improve the space utilization rate of the fresh air cavity V012.

[0137] In some embodiments of the present application, the volute assembly 9 is provided with a guide piece, and the shielding piece 121 moves linearly between the first position and the second position under the guidance of the guide piece.

[0138] The guide piece can guide the shielding piece 121 to move linearly between the first position and the second position, so that the shielding piece 121 can move more stably, thereby improving the use reliability of the shielding piece 121.

[0139] Referring to Figure 10 and Figure 11In some embodiments of the present application, the guide is a sliding column 931 arranged in the fresh air cavity V012, and the blocking member 121 is provided with a sliding block 1211 on one side facing the fresh air cavity V012, and the sliding block 1211 is in sliding cooperation with the sliding column 931.

[0140] In some embodiments of the present application, the elastic member 122 is a spring, and the spring is sleeved on the outside of the sliding column 931 and abuts against the sliding block 1211.

[0141] Specifically, when the purification member 11 is arranged in the fresh air cavity V012, the blocking member 121 is moved to the first position and abuts against one side of the purification member 11, at this time the spring is compressed to store elastic potential energy; when the purification member 11 is taken out from the fresh air cavity V012, the acting force of the purification member 11 on the blocking member 121 disappears, and the blocking member 121 can be driven by the spring to move towards the second position, so as to block at least part of the mounting port 803.

[0142] In some embodiments not shown in the drawings of the present application, the blocking member 121 can be rotatably moved between the first position and the second position. Since the space occupied by the blocking member 121 when rotating overlaps with the space occupied when the purification member 11 is taken out and placed, but does not conflict in time, the blocking member 121 is arranged to open and close the mounting port 803 by rotating, which can reduce the internal space of the fresh air cavity V012, and is conducive to realizing the design of small structure.

[0143] In some embodiments of the present application, the elastic member 122 is a torsion spring.

[0144] For example, the blocking member 121 and the volute assembly 9 can be rotatably connected through a rotating shaft, and the torsion spring can be sleeved on the rotating shaft and abut against the blocking member 121 and the volute assembly 9. When the purification member 11 is arranged in the fresh air cavity V012, the blocking member 121 is rotated to the first position and abuts against the purification member 11, at this time the torsion spring generates a torque or a rotating force to store elastic potential energy; when the purification member 11 is taken out from the fresh air cavity V012, the acting force of the purification member 11 on the blocking member 121 disappears, and the blocking member 121 can be rotated towards the second position under the action of the torsion spring, so as to block at least part of the mounting port 803.

[0145] In some embodiments not shown in the drawings of the present application, the wall-mounted air conditioner 10000 further comprises an electric drive member (not shown in the drawings), which is connected with the blocking member 121 and used to drive the blocking member 121 to move between the first position and the second position.

[0146] For example, the wall-mounted air conditioner 10000 can comprise an in-place detection member (not shown in the drawings), which can detect the in-place state of the purification member 11 in the fresh air cavity V012.

[0147] Specifically, when the in-place detection member detects that the purification member 11 is located in the fresh air cavity V012, the electric drive member does not work, and the shielding member 121 is kept in the first position; when the in-place detection member detects that the purification member 11 is not in the fresh air cavity V012, that is, the in-place detection member detects that the purification member 11 is taken out from the fresh air cavity V012, the control electric drive member works, and the electric drive member can drive the shielding member 121 to move towards the second position, so as to shield at least part of the installation port 803 by using the shielding member 121.

[0148] Therefore, by arranging the electric drive member, the position of the shielding member 121 can be controlled in real time according to the in-place state of the purification member 11 in the fresh air cavity V012, the safety hazard is effectively eliminated, the electric drive member is convenient to control and easy to implement, does not need to be operated by the user alone, and is favorable to improve the user experience.

[0149] Reference Figure 12 and Figure 13 In some embodiments of the present application, one of the volute assembly 9 and the shielding member 121 is provided with a clamping groove 932, and the other is provided with a clamping buckle 1212.

[0150] In this way, after the purification member 11 is taken out from the fresh air cavity V012, the shielding member 121 moves to the position where the clamping buckle 1212 and the clamping groove 932 are clamped, so as to keep the shielding member 121 in the second position.

[0151] Therefore, by arranging the clamping groove 932 and the clamping buckle 1212, the shielding member 121 can be kept in the second position, that is, kept in the position of shielding at least part of the installation port 803, so as to prevent the user's fingers or foreign matters from extending into the volute assembly 9, and eliminate the safety hazard.

[0152] In some embodiments of the present application, as shown in Figure 11 The purification member 11 includes a filter screen, the filter screen covers the entire air inlet end of the fresh air fan 6, the filter screen has a large coverage area and a large filtering area, and has a good filtering effect. The arrangement of the filter screen helps to ensure sufficient contact area with the flowing air, and has a light weight and a small air flow noise. For example, the filter screen is a Hepa screen, and thus has strong adsorption force and strong filtering effect on dust in the air.

[0153] In some embodiments of the present application, the filter screen is plate-shaped, so that the filter screen as a whole is thin and does not occupy a too thick size when placed in the bidirectional ventilation assembly.

[0154] In some embodiments of the present application, the filter screen is square-shaped, so that the positioning and installation of the filter screen are facilitated.

[0155] Specifically, the fresh air cavity V012 is provided with a sliding rail 933, and the square frame of the filter screen can be matched with the sliding rail 933. The extension direction of the sliding rail 933 can be perpendicular to the axis of the fresh air fan 6, so that the axis of the fresh air fan 6 is perpendicular to the filter screen; or the extension direction of the sliding rail 933 is arranged to be inclined relative to the axis of the fresh air fan 6, so that the axis of the fresh air fan 6 is arranged to be inclined relative to the filter screen, for example, the filter screen is gradually inclined to the fresh air fan 6 in a direction away from the mounting port 803.

[0156] In some embodiments of the present application, with reference to Figure 8 , a part of the fresh air cavity V012 constitutes an empty cavity V0121, the empty cavity V0121 is located on the side of the purification member 11 away from the fresh air fan 6, and the fresh air inlet 801 communicates with the empty cavity V0121.

[0157] For example, the purification member 11 is arranged in the fresh air cavity V012 close to the fresh air fan 6, and the part of the fresh air cavity V012 away from the fresh air fan 6 is the empty cavity V0121, that is, between the face wind of the purification member 11 and the inner surface of the fan cover 93 is the empty cavity V0121, so that the empty cavity V0121 is in a negative pressure state when the fresh air fan 6 operates, so that the airflow can automatically flow into the empty cavity V0121 from the fresh air inlet 801, reducing the air flow resistance.

[0158] The empty cavity V0121 corresponds to the air inlet negative pressure cavity of the fresh air fan 6, and the air inlet negative pressure cavity has many advantages:

[0159] 1. Improve the air inlet efficiency. For example, by arranging the negative pressure cavity to increase the buffer space of the fresh air fan 6 on the air suction side, the fresh air fan 6 can more easily suck air, thereby increasing the air inlet amount of the fresh air fan 6. Moreover, the existence of the negative pressure cavity allows the fresh air to be buffered and adjusted in the negative pressure cavity before entering the fresh air fan 6, thereby reducing the fluctuation and turbulence of the airflow, which is beneficial to improve the air inlet stability of the fresh air fan 6. If there is no empty cavity V0121 and no buffer space, the flow resistance will increase, and the operating power consumption of the fresh air fan 6 will increase.

[0160] 2. Optimize the airflow distribution. For example, by buffering and guiding the negative pressure cavity, the airflow can be guided to be sucked into the fresh air fan 6 along the axial direction.

[0161] 3. Reduce airflow impact and absorb noise.

[0162] In this way, while improving the air inlet amount of the fresh air device, the overall air inlet reliability and stability can be improved.

[0163] In some embodiments of the present application, in combination with Figures 2-3 , Figure 12As shown, in the front-rear direction of the main body 1000, the mounting port 803 is located on the front side of the main body 1000, and the purification element 11 can be removed without interference from the fresh air inlet 801 and the exhaust air outlet 922. For example, the front side of the casing 1 is provided with a panel 15 that can be opened and closed. When the panel 15 is opened or the panel 15 is turned upward, the mounting port 803 can be exposed, facilitating the removal of the purification element 11.

[0164] It is also not excluded that in some schemes, the mounting port 803 is arranged at the bottom of the main body 1000.

[0165] In some embodiments, the number of fresh air outlets can be one.

[0166] In some embodiments, the number of fresh air outlets can be multiple, for example, two, three, four or more. By arranging multiple fresh air outlets, the amount of air can be increased.

[0167] In some embodiments, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in the same direction.

[0168] In some embodiments, the number of fresh air outlets is multiple, and the multiple fresh air outlets are arranged in different directions.

[0169] In some embodiments, the fresh air outlet includes a first fresh air outlet 802 and a second fresh air outlet 808, and the first fresh air outlet 802 and the second fresh air outlet 808 are both in communication with the fresh air duct V01. The rotation of the fresh air fan 6 can cause outdoor air to enter the fresh air duct V01 from the fresh air inlet 801, and the outdoor air entering the fresh air duct V01 can enter the indoor space from the first fresh air outlet 802 and the second fresh air outlet 808.

[0170] Referring to Figures 2-4 , Figure 6 and Figure 12 In some embodiments, the first fresh air outlet 802 is located below the main body 1000 to guide the fresh air to flow forward and downward to the indoor space. Thus, the air blown out of the first fresh air outlet 802 can be directly blown to the user.

[0171] Specifically, the first fresh air outlet 802 can discharge air to the indoor space through the heat exchange air outlet 102, so that it is not necessary to re-open the casing air outlet, simplifying the processing technology of the casing 1. Moreover, the first fresh air outlet 802 and the heat exchange air outlet 102 have overlapping air outlet areas, which is conducive to the mixing of fresh air and indoor air after heat exchange, on the one hand, improving the uniformity of the mixed fresh air in the indoor air, on the other hand, the fresh air can absorb the cold or heat of the indoor air after heat exchange, so that the temperature of the fresh air tends to the indoor temperature, improving the air blowing comfort.

[0172] Alternatively, the casing 1 is provided with a casing air outlet, which is spaced apart from the heat exchange air outlet 102, and the first fresh air outlet 802 can discharge fresh air to the indoor environment through the casing air outlet. The casing air outlet can be correspondingly arranged below the casing 1.

[0173] Since the heat exchange air inlet 101 is located above the heat exchange air outlet 102, the heat exchange air outlet 102 is relatively low on the casing 1. Thus, the first fresh air outlet 802 blows fresh air from below, so that the fresh air outlet area of the casing air outlet is close to or even partially overlaps the fresh air outlet area of the heat exchange air outlet 102. This is conducive to mixing fresh air with indoor air after heat exchange, on the one hand, to improve the uniformity of the mixed fresh air in the indoor air, and on the other hand, to absorb the cold or heat of the indoor air after heat exchange, so that the temperature of the fresh air tends to the indoor temperature, and the blowing comfort is improved.

[0174] The first fresh air outlet 802 is opposite to the air inlet direction of the heat exchange air inlet 101, so that the fresh air blown from the first fresh air outlet 802 cannot be sucked into the heat exchange air inlet 101, reducing the proportion of fresh air in the heat exchange air inlet 101, and increasing the total air volume of the wall-mounted air conditioner 10000, and improving the overall circulation efficiency of the indoor air.

[0175] The first fresh air outlet 802 is located below the main body 1000, close to the space where people move, and convenient for people to observe the fresh air outlet condition. Thus, the fresh air outlet is visualized, which is conducive to improving the experience and observation of people.

[0176] When the first fresh air outlet 802 is located below the main body 1000, it is usually located on the front side below the main body 1000, so that the fresh air can flow forward and downward, ensuring that the fresh air can reach the ground and that the fresh air can reach a sufficient distance.

[0177] Referring to Figures 2-4 , Figure 6 and Figure 12 , in some embodiments, the second fresh air outlet 808 is located at the top of the main body 1000 to guide the fresh air to flow upward to the indoor environment. When the wall-mounted air conditioner 10000 is in a cooling mode, the air blown from the second fresh air outlet 808 can sink from top to bottom, thereby providing a top-to-bottom showering air experience for the user, the user feels cooler, and the indoor temperature can be lowered faster.

[0178] Referring to Figures 2-4 , in some embodiments, the number of the second fresh air outlet 808 is one.

[0179] Referring to Figure 6 and Figure 12In some embodiments, the number of the second fresh air outlets 808 is at least two, and the at least two second fresh air outlets 808 are arranged in the front-rear direction of the main body 1000.

[0180] With reference to Figures 6-11 The wall-mounted air conditioner 10000 further comprises an exhaust fan 7, which is an axial-inlet and radial-outlet centrifugal fan.

[0181] The exhaust fan 7 is located between the fresh air fan 6 and the heat exchange fan 41. In other words, the exhaust fan 7 is closer to the heat exchange fan 41 than the fresh air fan 6.

[0182] When the wall-mounted air conditioner 10000 is in cooling or heating, the heat exchange fan 41 is operated to drive the indoor air entering the casing 1 from the heat exchange air inlet 101 to flow through the indoor heat exchanger 2. The exhaust fan 7 is close to the heat exchange fan 41, and the inlet end of the exhaust fan 7 is close to the inlet end of the heat exchange fan 41, so the exhaust fan 7 can suck air from the inlet end of the heat exchange fan 41.

[0183] That is, when the exhaust fan 7 rotates, it can suck the indoor air entering the casing 1 from the heat exchange air inlet 101 to the exhaust fan 7, so that it is not necessary to additionally open a hole in the casing 1 to separately introduce air to the exhaust fan 7, thereby reducing the number of openings in the casing 1, simplifying the machining and manufacturing process of the casing 1, and increasing the aesthetic degree. In addition, the heat exchange air inlet 101 is generally large, so the amount of indoor air sucked into the casing 1 through the heat exchange air inlet 101 is large, which increases the air volume reaching the exhaust fan 7 and accelerates the exhaust efficiency.

[0184] In addition, in some embodiments, the fresh air fan 6 is arranged on the side of the exhaust fan 7 away from the indoor heat exchanger 2. When there is condensate water on one side of the indoor heat exchanger 2, the condensate water is less likely to reach the fresh air fan 6, reducing the risk of water accumulation and bacterial growth at the fresh air fan 6.

[0185] Both the fresh air fan 6 and the exhaust fan 7 are centrifugal fans, and the directions of the air flow of the fresh air fan 6 and the exhaust fan 7 can be reasonably arranged. For example, the fresh air fan 6 is axial-inlet and radial-outlet, the exhaust fan 7 is axial-inlet and radial-outlet, the fresh air fan 6 and the exhaust fan 7 are both inlet from the two ends away from each other, and then the fresh air and the exhaust air are both driven to be radial-outlet. The flow paths of the fresh air and the exhaust air do not need to overlap in the axial direction, and the paths do not need to intersect. This helps to reduce the design of the avoidance corner of the fresh air and exhaust air paths, reduce air resistance and energy consumption, ensure air volume, and reduce noise.

[0186] With reference to Figures 6-8, the exhaust air duct V02 is formed in the volute assembly 9, and the exhaust air inlet 921 and the exhaust air outlet 922 are formed on the volute assembly 9 and communicate with the exhaust air duct V02. The exhaust air fan 7 is configured to drive the indoor air to flow from the exhaust air inlet 921 to the exhaust air outlet 922.

[0187] The exhaust air fan 7 is arranged in the exhaust air duct V02, and rotation of the exhaust air fan 7 can drive the indoor air to flow from the exhaust air inlet 921 to the exhaust air outlet 922.

[0188] Therefore, by arranging the exhaust air duct V02 and the exhaust air fan 7, when the indoor air is relatively dirty or the air quality is poor, the exhaust air fan 7 can be used to suck and exhaust the dirty air in the indoor space. After the amount of indoor air is reduced, fresh air can be sucked from the outdoor or other rooms through doors and windows, so as to reduce the degree of dirtiness of the indoor air.

[0189] The fresh air fan 6, the exhaust air fan 7, and the volute assembly 9 form a bidirectional air exchange assembly, which is arranged in the main body 1000. The bidirectional air exchange assembly can provide fresh air for the indoor space and can exhaust the indoor air to the outdoor space.

[0190] It should be noted that, in the wall-mounted air conditioner 10000, the operation mode of the bidirectional air exchange assembly can be set according to actual use requirements.

[0191] In some embodiments, the bidirectional air exchange assembly can simultaneously operate in the fresh air mode and the exhaust air mode, that is, the fresh air duct V01 and the exhaust air duct V02 can be simultaneously opened, so that the dirty air in the indoor space can flow to the outdoor space, and at the same time, fresh air from the outdoor space can flow into the indoor space. By using the combination of the air inlet and the air outlet, the air flow improvement efficiency of the indoor space can be improved, so that the user demand can be met in time when the user needs to exhaust or update the indoor air.

[0192] In addition, since the indoor air is exhausted to the outdoor space while the fresh air from the outdoor space is supplemented to the indoor space, the amount of indoor air is sufficient, and the indoor air is more easily sucked. For example, when there is a leakage of irritating gas (such as gas released by home decoration materials), coal gas, or other gas, the bidirectional air exchange assembly can be set to simultaneously operate in the fresh air mode and the exhaust air mode, so as to achieve rapid air exchange. Compared with the conventional fresh air structure that only introduces fresh air, the bidirectional air exchange assembly in some embodiments has a larger purification flow rate per unit time, a higher air exchange efficiency, and a better purification effect.

[0193] And avoid the indoor temperature changes sharply when ventilation, avoid causing indoor personnel because of temperature sudden rise or sudden drop of discomfort. And the main body 1000 is located higher, the ventilation position will not cause discomfort because of too close to people.

[0194] In some embodiments, the bidirectional ventilation assembly can be realized by means of a valve to run the new air mode and exhaust mode, that is, the bidirectional ventilation assembly opens the new air mode and closes the exhaust mode, at this time only the new air duct V01 is ventilated, and the exhaust air duct V02 is not ventilated. Or the bidirectional ventilation assembly opens the exhaust mode and closes the new air mode, at this time the new air duct V01 is not ventilated, and the exhaust air duct V02 is ventilated.

[0195] It can be understood that when the wall-mounted air conditioner 10000 is in a cooling state, the bidirectional ventilation assembly inhales fresh air from the outdoor to the indoor, and the cold energy generated by the wall-mounted air conditioner 10000 can still remain in the indoor, and the cold energy loss is small. The indoor air is discharged to the outdoor through the exhaust air duct V02, and by setting the exhaust air volume to be less than the fresh air volume, the cold energy loss can be reduced.

[0196] The bidirectional ventilation assembly is arranged at one end of the length direction of the heat exchange fan 41, and compared with the main body 1000 without the bidirectional ventilation assembly, only the transverse length is increased, and the height and thickness of the main body 1000 can be basically unchanged or slightly changed, so that the main body 1000 is light and thin in appearance, and when hung on the wall, it will not be too conspicuous to affect the indoor space layout, and will not be too heavy to cause difficulty in fixing the wall-mounted air conditioner 10000, thereby reducing the risk of falling off the wall. The wall-mounted air conditioner 10000 is still a light and thin model as a whole, which is not only beautiful when hung on the wall, but also controllable in weight.

[0197] Referring to Figure 4 and Figure 5 In some embodiments, the motor 42 drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate synchronously in the working state.

[0198] The fresh air fan 6 and the exhaust fan 7 are both centrifugal fans, and the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are all driven by the same motor 42, which not only saves the number of motors 42, reduces the overall size and saves cost, but also keeps the three fans stacked along the axial direction of the motor 42.

[0199] In addition, the centrifugal fan itself is relatively flat in the axial direction, and the fresh air fan 6 and the exhaust fan 7 are thus stacked to reduce the overall axial size occupied, so that the length of the main body 1000 does not need to be too long. Since the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are all driven by the same motor 42, the three fans rotate synchronously, and the fresh air fan 6 and the exhaust fan 7 are in step with each other, so that the fresh air fan 6 and the exhaust fan 7 do not need to be separated by a large gap, and the axial distance between the fresh air fan 6 and the exhaust fan 7 can be arranged relatively close.

[0200] The motor 42, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are arranged in the length direction of the main body 1000 instead of being 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.

[0201] In the above technical solution, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 share the same motor 42, so that the overall size can be reduced, the number of motors 42 can be reduced, and the cost can be saved. The architecture of the wall-mounted air conditioner 10000 is as follows from right to left: the motor 42, the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6, and the exhaust fan 7 is between the heat exchange fan 41 and the fresh air fan 6. The heat exchange fan 41 is on the side close to the motor 42, the heat exchange fan 41 is longer, and the heat exchange fan 41 close to the motor 42 makes the overall dynamic balance performance of the architecture better and the overall integration higher.

[0202] The heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are driven by the same motor 42, so that they can be started and stopped at the same time and have the same speed. In the related art, the fresh air fan 6 is driven by a separate motor 42 and the exhaust fan 7 is driven by a separate motor 42, which causes high cost. The mode of driving three fans by one motor 42 in the present application can save two motors 42 and greatly reduce the cost.

[0203] In some embodiments of the present application, with reference to Figure 5 , Figures 14-15 The motor 42 includes an output shaft 421, and the heat exchange fan 41 is fixedly connected with the output shaft 421. The output shaft 421 drives the heat exchange fan 41 to rotate when rotating.

[0204] In some embodiments of the present application, with reference to Figure 14 and Figure 15 The wall-mounted air conditioner 10000 further includes a transmission shaft 43, and the transmission shaft 43 is adapted to be fixedly connected with the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6. When the output shaft 421 drives the heat exchange fan 41 to rotate, the heat exchange fan 41 drives the exhaust fan 7 and the fresh air fan 6 to rotate synchronously through the transmission shaft 43. Thus, one motor 42 drives the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 to rotate, the number of motors 42 is small, and the cost is saved.

[0205] In some embodiments of the present application, with reference to Figure 14 and Figure 15 The output shaft 421 and the transmission shaft 43 are coaxially arranged.

[0206] In some embodiments of the present application, the transmission shaft 43 is adapted to be formed in one piece with one of the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6, and the other two of the heat exchange fan 41, the exhaust fan 7 and the fresh air fan 6 are fixedly installed on the transmission shaft 43.

[0207] For example, the transmission shaft 43 is formed in one piece with the heat exchange fan 41, and the exhaust fan 7 and the fresh air fan 6 are fixedly installed on the transmission shaft 43. The transmission shaft 43 and the heat exchange fan 41 can be fixed by welding or be an integrally injection molded piece. The exhaust fan 7 and the transmission shaft 43, and the fresh air fan 6 and the transmission shaft 43 can be non-circular surface fit or interference fit to prevent relative rotation between the exhaust fan 7 and the transmission shaft 43, and between the fresh air fan 6 and the transmission shaft 43.

[0208] For another example, the transmission shaft 43 is formed in one piece with the exhaust fan 7, and the heat exchange fan 41 and the fresh air fan 6 are fixedly installed on the transmission shaft 43. The transmission shaft 43 and the exhaust fan 7 can be fixed by welding or be an integrally injection molded piece. The heat exchange fan 41 and the transmission shaft 43, and the fresh air fan 6 and the transmission shaft 43 can be non-circular surface fit or interference fit to prevent relative rotation between the heat exchange fan 41 and the transmission shaft 43, and between the fresh air fan 6 and the transmission shaft 43.

[0209] For another example, the transmission shaft 43 is formed in one piece with the fresh air fan 6, and the exhaust fan 7 and the heat exchange fan 41 are fixedly installed on the transmission shaft 43. The transmission shaft 43 and the fresh air fan 6 can be fixed by welding or be an integrally injection molded piece. The exhaust fan 7 and the transmission shaft 43, and the heat exchange fan 41 and the transmission shaft 43 can be non-circular surface fit or interference fit to prevent relative rotation between the exhaust fan 7 and the transmission shaft 43, and between the heat exchange fan 41 and the transmission shaft 43.

[0210] In some embodiments of the present application, as shown in Figs. Figure 5 , Figure 14 and Figure 15 , the wall-mounted air conditioner 10000 further comprises a first bearing seat 131 and a first bearing 132, the first bearing seat 131 is arranged on the base 3, the first bearing 132 is arranged in the first bearing seat 131, and the first bearing 132 is used to support the transmission shaft 43.

[0211] The motor 42, the heat exchange fan 41, the transmission shaft 43, the exhaust fan 7 and the fresh air fan 6 constitute a one-shaft three-fan structure, and by arranging the first bearing 132, the stability of the one-shaft three-fan structure is improved, and the runout of the one-shaft three-fan structure is reduced.

[0212] In some embodiments of the present application, as shown in Figs. Figure 15As shown, the wall-mounted air conditioner 10000 further comprises a second bearing 133, which is arranged between the exhaust fan 7 and the fresh air fan 6 and is used to support the transmission shaft 43.

[0213] By arranging the second bearing 133, the stability of the one-shaft three-fan structure can be further improved, and the runout of the one-shaft three-fan structure can be reduced. In particular, since the exhaust fan 7 and the fresh air fan 6 are far away from the motor 42, when the rotation of the output shaft 421 of the motor 42 is transmitted to the exhaust fan 7 and the fresh air fan 6, the exhaust fan 7 and the fresh air fan 6 will generate a large runout, which will affect the air volume and generate noise. In order to solve this problem, the second bearing 133 is arranged between the exhaust fan 7 and the fresh air fan 6 to support the transmission shaft 43. The second bearing 133 can significantly reduce the runout of the exhaust fan 7 and the fresh air fan 6 and alleviate the runout problem of the exhaust fan 7 and the fresh air fan 6. The second bearing 133 can correct the concentricity of the exhaust fan 7 and the fresh air fan 6.

[0214] Referring to Figures 6-8 , Figure 10 In some embodiments of the present application, the volute assembly 9 comprises a fresh air volute 91 located at the other end of the length direction of the heat exchange fan 41, and a volute cavity V011 is formed in the fresh air volute 91.

[0215] The volute assembly 9 further comprises a fan cover 93 which is detachably connected to the side of the fresh air volute 91 away from the heat exchange fan 41, and a fresh air cavity V012 is formed in the fan cover 93.

[0216] The volute assembly 9 further comprises an exhaust volute 92 which is detachably connected to the side of the fresh air volute 91 facing the heat exchange fan 41, and an exhaust air duct V02 is formed in the exhaust volute 92.

[0217] When installing the bidirectional ventilation assembly on the main body 1000, the fresh air fan 6 can be placed in the fresh air volute 91 first, the exhaust fan 7 can be placed in the exhaust volute 92, the exhaust fan 7 and the fresh air fan 6 can be connected together through the transmission shaft 43, then the fresh air volute 91 and the exhaust volute 92 can be connected and fixed through fasteners, the fresh air volute 91 and the fan cover 93 can be connected and fixed through fasteners, and finally the transmission shaft 43 and the heat exchange fan 41 can be connected together and installed on the base 3.

[0218] Optionally, the fastener can be a bolt, a screw, etc., which can firmly connect two parts.

[0219] Therefore, by dividing the volute assembly 9 into at least the fresh air volute 91, the fan cover 93, and the exhaust volute 92 for separate machining, the manufacturing and assembly difficulty can be reduced, and the quality control of such a complex shell can be facilitated after separate manufacturing.

[0220] The new air volute 91 is open at one end towards the fan cover 93, the fan cover 93 is open at one end towards the new air volute 91, and the open end of the new air volute 91 and the open end of the fan cover 93 are connected.

[0221] That is, in the embodiment of the present application, the protective net between the new air volute 91 and the fan cover 93 is cancelled, that is, the protective net between the new air fan 6 and the purification component 11 is cancelled, so that the air flow resistance can be reduced, and the air suction effect of the new air fan 6 can be improved.

[0222] Based on this, in the embodiment of the present application, the movable shielding piece 121 is arranged at the installation opening 803, so that after the purification component 11 is taken out, the shielding piece 121 can shield at least part of the installation opening 803, prevent the user's fingers or foreign matters from entering the volute assembly 9 and being damaged by the new air fan 6, or damaging the new air conditioner, eliminate the safety hidden danger, and ensure the safety after the purification component 11 is taken out.

[0223] Referring to Figures 6-8 , Figure 10 and Figure 12 , in some embodiments of the present application, the new air volute 91 comprises: a first volute half 911 and a second volute half 912, the second volute half 912 is arranged above the first volute half 911, and the second volute half 912 is detachably connected with the first volute half 911, the first volute half 911 and the second volute half 912 are both detachably connected with the exhaust air volute 92, and a volute cavity V011 is formed in the first volute half 911 and the second volute half 912.

[0224] The fan cover 93 is located at a side of the first volute half 911 and the second volute half 912 away from the heat exchange fan 41, and is detachably connected with the first volute half 911 and the second volute half 912.

[0225] It can be understood that the second volute half 912 is detachably connected with the first volute half 911, which can be fixed and connected by a fastener or a buckle 1212 structure. The first volute half 911 and the second volute half 912 are both detachably connected with the exhaust air volute 92, which can be fixed and connected by a fastener or a buckle 1212 structure. The fan cover 93 is detachably connected with the first volute half 911 and the second volute half 912, which can be fixed and connected by a fastener or a buckle 1212 structure.

[0226] The second volute half 912 is detachably connected with the first volute half 911, the first volute half 911 and the second volute half 912 are both detachably connected with the exhaust volute 92, and the fan cover 93 is detachably connected with the first volute half 911 and the second volute half 912, so that assembly is facilitated, and subsequent adjustment and maintenance are facilitated.

[0227] In the technical solution, the fresh air volute 91 is divided into the first volute half 911 and the second volute half 912 for separate machining, so that manufacturing and assembly difficulty is reduced, and quality control is facilitated after separate machining.

[0228] With reference to Figure 10 and Figure 12 In some embodiments of the present application, the fresh air inlet 801 and the mounting port 803 are formed on the fan cover 93. The fresh air inlet 801 and the mounting port 803 are both in communication with the fresh air cavity V012, so that the purification member 11 can be mounted into the fresh air cavity V012 through the mounting port 803, outdoor air can enter the fresh air cavity V012 through the fresh air inlet 801, flow through the purification member 11, and then enter the volute cavity V011 to be discharged into the room through the fresh air outlet.

[0229] With reference to Figure 10 and Figure 12 In some embodiments of the present application, the first volute half 911 and the fan cover 93 enclose the first fresh air outlet 802. The first fresh air outlet 802 enclosed by the first volute half 911 and the fan cover 93 is in communication with the volute cavity V011, so that indoor air in the volute cavity V011 can be discharged into the room through the first fresh air outlet 802, and manufacturing difficulty of the first fresh air outlet 802 is reduced, and quality control is facilitated.

[0230] With reference to Figure 10 and Figure 12 In some embodiments of the present application, the second volute half 912 and the fan cover 93 enclose the second fresh air outlet 808. The second fresh air outlet 808 enclosed by the second volute half 912 and the fan cover 93 is in communication with the volute cavity V011, so that indoor air in the volute cavity V011 can be discharged into the room through the second fresh air outlet 808, and manufacturing difficulty of the second fresh air outlet 808 is reduced, and quality control is facilitated.

[0231] With reference to Figure 10 and Figure 12 In some embodiments of the present application, the exhaust air inlet 921 is formed on the exhaust volute 92.

[0232] The air exhaust inlet 921 can be opposite to the axial air inlet end of the air exhaust fan 7, so that the air exhaust fan 7 has small air resistance when taking in air from the air exhaust inlet 921, and the air exhaust amount can be ensured. When the air exhaust amount is relatively large, a smaller air exhaust fan 7 can be selected, and the size of the bidirectional air exchange assembly can be further reduced.

[0233] The air exhaust inlet 921 is axially directed to the indoor heat exchanger 2, that is, the air inlet area of the air exhaust inlet 921 is directed to the indoor heat exchanger 2. In this way, the air exhaust inlet 921 is close to the heat exchange air inlet 101, the air inlet amount at the heat exchange air inlet 101 is large, and part of the air entering the casing 1 from the heat exchange air inlet 101 can enter the air exhaust duct V02 through the air exhaust inlet 921, so that the air amount at the air exhaust inlet 921 is sufficient.

[0234] In some embodiments, as shown in Figures 2-4 The heat exchange air inlet 101 and the air exhaust inlet 921 form a first communication duct V04, the indoor air is taken into the first communication duct V04 by the rotation of the air exhaust fan 7, and the indoor air enters the air exhaust duct V02 through the air exhaust inlet 921.

[0235] That is, the heat exchange air inlet 101 and the air exhaust inlet 921 do not need to be connected by a solid pipe, and the air flow is only taken in from the top by air pressure.

[0236] Referring to Figure 10 and Figure 12 In some embodiments of the present application, the air exhaust volute 92 and the first volute half 911 enclose the air exhaust outlet 922. The air exhaust outlet 922 enclosed by the air exhaust volute 92 and the first volute half 911 can communicate the air exhaust outlet 922 with the air exhaust duct V02, so that the indoor air entering the air exhaust duct V02 can be discharged to the indoor space through the air exhaust outlet 922, and can also reduce the manufacturing difficulty of the air exhaust outlet 922 and facilitate quality control.

[0237] In some embodiments, the air exhaust fan 7 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the air exhaust fan 7 can also be a resin part, a metal part, etc.

[0238] In some embodiments, the fresh air fan 6 can be a plastic part, so as to be light in weight and low in cost. In some embodiments, the fresh air fan 6 can also be a resin part, a metal part, etc.

[0239] Similarly, the air exhaust volute 92 can be a plastic part, so as to be light in weight and low in cost. For example, the air exhaust volute 92 can be an injection molded part. In some embodiments, the air exhaust volute 92 can also be a resin part, a metal part, etc.

[0240] The new air volute 91 can be a plastic part, thereby being light in weight and low in cost. For example, the new air volute 91 can be an injection molded part. In some embodiments, the new air volute 91 can also be a resin part, a metal part, or the like.

[0241] The fan cover 93 can be a plastic part, thereby being light in weight and low in cost. For example, the fan cover 93 can be an injection molded part. In some embodiments, the fan cover 93 can also be a resin part, a metal part, or the like.

[0242] In some embodiments of the present application, the fan cover 93 is formed with a purification air inlet for communicating with the room. The rotation of the new air fan 6 can cause the indoor air to enter the new air cavity V012 from the purification air inlet, pass through the purification part 11 for purification, and then enter the volute cavity V011 from the new air outlet and enter the room. In this way, the indoor air can enter the new air duct V01 from the purification air inlet, pass through the purification part 11, and then enter the room from the new air outlet.

[0243] In this way, when the indoor air is polluted, the circulation of the indoor air can be achieved, and the purification can be performed in the circulation. In this way, the indoor air can be purified without introducing outdoor fresh air, thereby improving the cleanliness. Since no outdoor fresh air is introduced, the cold or hot air from the outdoor without heat exchange is not suddenly blown into the room during the purification of the indoor air, thereby avoiding the discomfort caused by the sudden change of the indoor temperature.

[0244] In some embodiments of the present application, the purification air inlet can communicate with the heat exchange air inlet 101, and no connecting pipe is needed between the purification air inlet and the heat exchange air inlet 101, thereby reducing the number of parts, reducing the occupied volume, and facilitating the layout.

[0245] In some embodiments of the present application, the purification air inlet is located at the bottom of the fan cover 93 and is arranged downward. It can be understood that the new air inlet 801 is located below the main body 1000, and the new air inlet 801 and the purification air inlet are both located at the bottom of the fan cover 93 and extend downward, thereby facilitating the molding. Moreover, in use, one of the two is opened. At this time, the new air inlet 801 and the purification air inlet are both located at the bottom of the fan cover 93, thereby facilitating the centralized arrangement of the switches to select one of the air inlets to be opened, and reducing the number of switches.

[0246] In some embodiments, the air inlet direction of the purification air inlet is perpendicular to the length direction of the heat exchange fan 41. It can be understood that the air inlet direction of the purification air inlet is perpendicular to the length direction of the heat exchange fan 41, the purification air inlet is far away from the air inlet 921, thereby avoiding excessive air suction energy consumption caused by the close distance between the purification air inlet and the air inlet 921. Moreover, the different directions of the purification air inlet and the air inlet 921 help to expand the negative pressure area, help a large amount of indoor air to flow into the negative pressure area, and ensure the air volume of the exhaust air and the indoor new air.

[0247] In some embodiments of the present application, the fresh air inlet 801 is located below the main body 1000 in the height direction of the main body 1000. It can be understood that the fresh air inlet 801 needs to be connected to a pipeline to introduce outdoor air, which is referred to as a fresh air introduction pipe herein. The fresh air introduction pipe can be a part of the wall-mounted air conditioner 10000, or a fresh air introduction pipe configured by the user after purchasing the wall-mounted air conditioner 10000.

[0248] By arranging the fresh air inlet 801 below the main body 1000, the fresh air introduction pipe can be connected to the fresh air inlet 801 from below, and the connection extends generally in the up-down direction rather than in the front-back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0249] Referring to Figure 6 and Figure 7 In some embodiments, the exhaust air outlet 922 is located below the main body 1000 in the height direction of the main body 1000. Similarly, the exhaust air outlet 922 needs to be connected to a pipeline to guide indoor air to the outside, which is referred to as an exhaust air introduction pipe herein. The exhaust air introduction pipe can be a part of the wall-mounted air conditioner 10000, or an exhaust air introduction pipe configured by the user after purchasing the wall-mounted air conditioner 10000.

[0250] By arranging the exhaust air outlet 922 below the main body 1000, the exhaust air introduction pipe can be connected to the exhaust air outlet 922 from below, and the connection extends generally in the up-down direction rather than in the front-back direction to make the main body 1000 too thick, so that the wall-mounted air conditioner 10000 can still maintain a light and thin appearance.

[0251] In some embodiments, the wall-mounted air conditioner 10000 can include a fresh air introduction pipe connected to the fresh air inlet 801, and an exhaust air introduction pipe connected to the exhaust air outlet 922, as shown in Figure 1 and Figure 2 As shown, the side wall of the cabinet 1 is provided with a pipe avoiding opening 104, and the fresh air introduction pipe is bent to extend transversely after being connected to the fresh air inlet 801 from below the main body 1000, and then extends out of the pipe avoiding opening 104 on the side wall of the cabinet 1, and then extends to the outside. The exhaust air introduction pipe is bent to extend transversely after being connected to the exhaust air outlet 922 from below the main body 1000, and then extends out of the pipe avoiding opening 104 on the side wall of the cabinet 1, and then extends to the outside.

[0252] The fresh air introduction pipe and the exhaust air introduction pipe are two independent pipes, which can help the fresh air flow path and the exhaust air flow path to be separated from each other, without crossing each other, reducing the risk of air leakage caused by mutual cross flow.

[0253] It can be understood that the main body 1000 is usually provided 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 with the compressor and the outdoor heat exchanger. The drain pipe is used to drain the condensate water generated in the wall-mounted air conditioner 10000.

[0254] The guide pipe avoiding opening 104 is arranged on the side wall of the casing 1, and then the fresh air inlet pipe and the exhaust air outlet pipe are transversely arranged and then led out. At least one of the fresh air inlet pipe and the exhaust air outlet pipe is arranged in parallel 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 outside the parallel pipes, so that the plurality of pipes are in the shape of one pipe in appearance. Therefore, the wall-mounted air conditioner 10000 has a small number of connecting pipes and a simple appearance after installation, which is convenient for assembly and avoids the risk of knocking the plurality of pipes.

[0255] In some embodiments of the present application, as shown in Figure 6 and Figure 7 The exhaust air outlet 922 of the exhaust air duct V02 and the first fresh air outlet 802 of the fresh air duct V01 are arranged in a staggered manner on the outer periphery of the bidirectional air exchange assembly. In this way, on the one hand, the exhaust air outlet pipe connected to the exhaust air outlet 922 and the fresh air inlet pipe connected to the fresh air inlet 801 are arranged in a staggered manner, which avoids interference caused by the close distance between the two pipe joints. On the other hand, the flow paths of the fresh air and the exhaust air in the bidirectional air exchange assembly are not crossed.

[0256] In some embodiments, the exhaust direction of the exhaust air outlet 922 is downward, and the exhaust direction of the first fresh air outlet 802 is forward. In this way, the pipe connection positions of the exhaust air outlet 922 and the first fresh air outlet 802 are directly staggered. The downward exhaust direction of the exhaust air outlet 922 facilitates the connection of the exhaust air outlet pipe and the wall installation of the exhaust air outlet pipe. The forward exhaust direction of the first fresh air outlet 802 facilitates the forward delivery of the fresh air, which increases the fresh air delivery range.

[0257] For example, the exhaust air outlet 922 is located at the rear side of the exhaust air volute 92, and the exhaust direction of the exhaust air outlet 922 is downward. In this way, when the exhaust air outlet pipe is connected to the exhaust air outlet 922, the exhaust air outlet pipe does not excessively lengthen the wall-mounted air conditioner 10000. In addition, the exhaust air outlet 922 is arranged on the wall side of the exhaust air volute 92, which facilitates the formation of a rear wide and front narrow shape of the main body 1000.

[0258] When the main body 1000 is formed in a rear wide and front narrow shape, the wider back is installed against the wall. When people observe the wall-mounted air conditioner 10000, they see the narrower front, which is conducive to creating a lighter and thinner impression of the wall-mounted air conditioner 10000. In this way, the thickness of the wall-mounted air conditioner 10000 is reduced, which further reduces the oppressive feeling caused by the wall-mounted air conditioner 10000 installed on the wall.

[0259] Referring toFigure 6 And Figure 7 In some embodiments, the first fresh air outlet 802 is downwardly inclined while the air outlet direction is downward. In this way, the wall-mounted air conditioner 10000 can send fresh air forward, ensuring that the fresh air can reach the ground and that the fresh air can be sent to a sufficient distance.

[0260] For example, the first fresh air outlet 802 is located on the front side of the exhaust air outlet 922, so that the first fresh air outlet 802 is staggered with the exhaust air outlet 922 at a greater distance, which is more conducive to reducing mutual interference and facilitating pipe connection.

[0261] In some embodiments, in the height direction of the main body 1000, the fresh air inlet 801 is located below the main body 1000, and in the length direction of the heat exchange fan 41, the first fresh air outlet 802 is located between the fresh air inlet 801 and the exhaust air outlet 922. In this way, the fresh air inlet 801, the first fresh air outlet 802, the exhaust air outlet 922, and the pipe connection position are compact, which is conducive to reducing the overall size.

[0262] Referring to Figure 3 In some embodiments of the present application, the wall-mounted air conditioner 10000 further comprises an end plate 31, which is located at one end of the indoor heat exchanger 2 close to the exhaust air fan 7, and the end plate 31 is connected with the indoor heat exchanger 2. The end plate 31 is used to mount the indoor heat exchanger 2 on the base 3.

[0263] The wall-mounted air conditioner 10000 further comprises a heat exchanger outlet pipe connected to one end of the indoor heat exchanger 2 facing the motor 42.

[0264] In the length direction of the main body 1000, the motor 42 and the heat exchanger outlet pipe at least partially overlap. In this way, the total length of the motor 42 and the heat exchanger outlet pipe in the length direction of the main body 1000 can be saved.

[0265] Referring to Figure 3 And Figure 4 In some embodiments of the present application, the axis of the exhaust air inlet 921 is directed towards the indoor heat exchanger 2, and a gap is provided between the end plate 31 and the volute assembly 9. Specifically, a gap is provided between the end plate 31 and the exhaust air volute 92, which forms a passage for indoor air from the heat exchange air inlet 101 to the exhaust air inlet 921. Specifically, when the exhaust air fan 7 rotates, indoor air can be sucked into the casing 1 through the heat exchange air inlet 101. At least part of the indoor air in the casing 1 can enter the exhaust air inlet 921 through the gap, and then enter the exhaust air duct V02.

[0266] The exhaust air inlet 921 is close to the end plate 31, and the gap between the end plate 31 and the volute assembly 9 can be used for air inlet circulation, without separately reserving an air inlet gap. The exhaust air fan 7 is a lateral air inlet centrifugal fan, and this air inlet mode requires a certain air inlet gap on the air inlet side to reduce the air inlet resistance. The exhaust air fan 7 is arranged on the side close to the heat exchange fan 41, and the gap between the end plate 31 and the volute assembly 9 can be used for air inlet.

[0267] Referring to Figure 16 and Figure 17 In some embodiments of the present application, the fresh air fan 6 includes a fresh air disc 61 and a fresh air blade 62, the fresh air blade 62 is located at the outer edge of the fresh air disc 61, and the fresh air blade 62 extends along the axial direction of the fresh air disc 61. The total thickness of the fresh air disc 61 and the fresh air blade 62 in the axial direction is h1. Here, the fresh air disc 61 on the fresh air fan 6 can be one or at least two spaced apart along the axial direction. h1 is the maximum size of the fresh air fan 6 in the axial direction of the fresh air fan 6.

[0268] The exhaust air fan 7 includes an exhaust air disc 71 and an exhaust air blade 72, the exhaust air blade 72 is located at the outer edge of the exhaust air disc 71, and the exhaust air blade 72 extends along the axial direction of the exhaust air disc 71. The total thickness of the exhaust air disc 71 and the exhaust air blade 72 in the axial direction is h2. Here, the exhaust air disc 71 on the exhaust air fan 7 can be one or at least two spaced apart along the axial direction. h2 is the maximum size of the exhaust air fan 7 in the axial direction of the exhaust air fan 7.

[0269] Wherein, h2 < h1. In this way, while ensuring that the fresh air volume is greater than the exhaust air volume, the main body 1000 part of the fresh air fan 6 has a larger axial thickness, so that the structural strength is larger and can bear a larger torque. The exhaust air fan 7 requires less air volume, and the smaller axial thickness of the main body 1000 part can appropriately reduce the exhaust air volume, while reducing the axial size of the bidirectional ventilation assembly.

[0270] Referring to Figure 16 and Figure 17 In some embodiments of the present application, the exhaust air fan 7 is a single-suction centrifugal fan with single-side air suction, and the exhaust air blade 72 extends along the axial direction of the exhaust air disc 71 away from the fresh air fan 6. In this way, the exhaust air blade 72 can reduce the competition for the air volume in the fresh air duct V01 when the exhaust air fan 7 rotates.

[0271] In some embodiments of the present application, the fresh air fan 6 is a single-suction centrifugal fan with single-side air suction, and the fresh air blade 62 includes a first fresh air blade 621, which extends along the axial direction of the fresh air disc 61 away from the exhaust air fan 7. In this way, the fresh air blade 62 can reduce the competition for the air volume in the exhaust air duct V02 when the fresh air fan 6 rotates.

[0272] Referring to Figure 16 and Figure 17 In some embodiments of the present application, the fresh air fan 6 is a double-suction centrifugal fan, the fresh air blades 62 include a first fresh air blade 621 and a second fresh air blade 622, the first fresh air blade 621 extends along the axial direction of the fresh air impeller disc 61 to a direction away from the exhaust fan 7, and the second fresh air blade 622 extends along the axial direction of the fresh air impeller disc 61 to a direction close to the exhaust fan 7.

[0273] In some embodiments of the present application, the outer diameter of the fresh air fan 6 is greater than the outer diameter of the heat exchange fan 41, so that the fresh air volume is not too small. For example, in an embodiment, the outer diameter of the fresh air fan 6 is 137 mm, and the outer diameter of the heat exchange fan 41 is 94 mm.

[0274] In some embodiments of the present application, the outer diameter of the exhaust fan 7 is greater than the outer diameter of the heat exchange fan 41, so that the exhaust volume is not too small. For example, in an embodiment, the outer diameter of the exhaust fan 7 is equal to the outer diameter of the fresh air fan 6, the outer diameter of the fresh air fan 6, the outer diameter of the exhaust fan 7 are all 137 mm, and the outer diameter of the heat exchange fan 41 is 94 mm.

[0275] As shown in Figure 17 In some embodiments of the present application, the outer diameter of the fresh air fan 6 is D1, and in the front-rear direction of the main body 1000, the thickness dimension of the main body 1000 is T, D1:T≥1:1.7, and D1:T≤1:1.3.

[0276] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness dimension of the main body 1000 is greater than or equal to 1:1.7, that is, D1:T≥1:1.7. When D1:T<1:1.7, the outer diameter of the fresh air fan 6 is too small, and the fresh air volume is too small, and the effect of introducing fresh air into the room is not good. By setting D1:T≥1:1.7, the outer diameter of the fresh air fan 6 will not be too small, the fresh air volume will not be too small, and the effect of introducing fresh air into the room will be better.

[0277] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness dimension of the main body 1000 is less than or equal to 1:1.3, i.e., D1:T≤1:1.3. When D1:T>1:1.3, the outer diameter of the fresh air fan 6 is too large, which occupies the space of the logarithmic spiral of the fresh air volute 91, causing the logarithmic spiral of the fresh air volute 91 to be incomplete or unable to be designed according to the maximum fresh air volume, resulting in too small fresh air volume and poor effect of introducing fresh air into the room. In the front-rear direction of the main body 1000, the outer diameter of the fresh air fan 6 plus the limit size of the logarithmic spiral of the reasonable fresh air volute 91 is equal to the thickness dimension of the main body 1000. By setting D1:T≤1:1.3, the outer diameter of the fresh air fan 6 is not too large, which does not excessively occupy the space of the logarithmic spiral of the fresh air volute 91, the logarithmic spiral of the fresh air volute 91 is complete, and can be designed according to the maximum fresh air volume, thereby ensuring that the fresh air volume is not too small and the effect of introducing fresh air into the room is good.

[0278] For example, D1:T can be 1:1.3, 1:1.4, 1:1.5, 1:1.6, 1:1.7, etc., and can also be other values between 1:1.7 and 1:1.3, which are not listed one by one here.

[0279] In some embodiments, the ratio of the outer diameter of the fresh air fan 6 to the thickness dimension of the main body 1000 is equal to 1:1.5, i.e., D1:T=1:1.5. The outer diameter of the fresh air fan 6 is not too small, and the fresh air volume is not too small, and the effect of introducing fresh air into the room is good. The outer diameter of the fresh air fan 6 is not too large, which does not excessively occupy the space of the logarithmic spiral of the fresh air volute 91, the logarithmic spiral of the fresh air volute 91 is complete, and can be designed according to the maximum fresh air volume, thereby ensuring that the fresh air volume is not too small and the effect of introducing fresh air into the room is good.
