Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a hanging type air conditioner. Background Art

[0002] At present, in some indoor units of wall-mounted air conditioners, the left and right sweeping function is realized by a sweeping assembly. The sweeping assembly includes a plurality of sweeping blades, which are arranged on a base and can swing left and right. According to the swinging method of the sweeping blades, they can be divided into manual and automatic. The automatic sweeping blades are driven by a sweeping motor to swing automatically.

[0003] In the prior art, the sweeping motors are mostly arranged on the left and right sides of the air outlet of the air conditioner, which not only increases the length of the indoor unit to a certain extent, but also the length of the sweeping assembly is relatively long, which makes the torque required by the sweeping motor larger. Therefore, the probability of failure of the electric sweeping motor will increase.

[0004] In addition, in the related art, the wind-sweeping motor is mostly installed on the base through a motor fixing seat. If the motor fixing seat only plays the role of fixing the wind-sweeping motor and does not shield the wind-sweeping motor, the wind-sweeping motor and some wind-sweeping components connected to it are exposed to the outside, which are easily affected by dust and foreign objects and cause obstacles to movement; if the motor fixing seat covers the wind-sweeping motor and is connected to the side of the base, the wind-sweeping motor is located in the cavity formed between the motor fixing seat and the side of the base, the heat generated by the wind-sweeping motor in the cavity cannot be dissipated in time, and there is a risk of motor failure during long-term operation, affecting the user experience. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent. To this end,

[0006] The utility model provides a hanging type air conditioner, comprising:

[0007] A housing comprising:

[0008] A base having an air outlet duct formed thereon;

[0009] An outer cover is arranged on the base and forms a heat exchange cavity with the base, an air-conditioning inlet communicating with the heat exchange cavity is provided on the top of the outer cover, an air-conditioning outlet is provided on the front bottom of the shell, and the heat exchange cavity is communicated with the air-conditioning outlet through the air outlet duct;

[0010] An indoor heat exchanger is disposed in the heat exchange cavity and is used to perform heat exchange on the indoor air in the heat exchange cavity;

[0013] A recessed portion is formed on the base, and a mounting cavity is formed between the recessed portion and the outer cover;

[0014] A through hole is formed on the base, wherein the through hole connects the mounting cavity and the air outlet duct;

[0015] A shaft sleeve connected to the wind sweeping assembly, the shaft sleeve being rotatably inserted into the through hole;

[0016] A wind sweeping motor is installed in the installation cavity, and a driving shaft of the wind sweeping motor is connected to the shaft sleeve to drive the wind sweeping blade to swing left and right;

[0017] At least one heat dissipation hole is formed on the recessed portion to connect the installation cavity with the indoor environment.

At the same time, when the wall-mounted air conditioner is working and the sweeping blades are swept and swung left and right, the air outlet duct is under negative pressure, and the installation cavity area is relatively under high pressure. Affected by the pressure difference, the wind near the sweeping motor will flow to the air outlet duct through the gap between the shaft sleeve and the through hole. By setting the heat dissipation holes, the indoor air can flow into the installation cavity through the heat dissipation holes, thereby forming a loop. The flow of indoor air will take away the heat generated by the sweeping motor, thereby improving the heat dissipation effect of the sweeping motor.

At the same time, when the wall-mounted air conditioner is working and the wind sweeping blades are swept and swung left and right, the air outlet duct is in negative pressure, and the installation cavity area is relatively in high pressure. Affected by the pressure difference, the wind near the wind sweeping motor will flow to the air outlet duct through the gap between the shaft sleeve and the through hole. By providing heat dissipation holes, indoor air can flow into the installation cavity through the heat dissipation holes, thereby forming a loop.

[0033] In some embodiments of the present application, the diameter of the heat dissipation hole is a, a≥1mm, a≤7mm; the heat dissipation holes within this diameter size range avoid the heat dissipation holes being too small to affect processing while ensuring the structural strength of the base.

[0034] In some embodiments of the present application, the diameter of the heat dissipation hole is a, where a>7mm and a≤15mm; the diameter of the heat dissipation hole is set to be no greater than 15mm to avoid the heat dissipation hole having a too large diameter that affects the structural strength of the base.

[0035] In some embodiments of the present application, the base includes a volute, which forms the lower wall of the air outlet duct, the recessed portion is located below the volute, and the through hole and the wind sweeping assembly are arranged on the volute to ensure that the wind sweeping motor has sufficient installation space.

The wall mounted air conditioner includes an air conditioner indoor unit, which is arranged indoors and used to exchange heat with the indoor environment. The wall mounted air conditioner may include an air conditioner outdoor unit, which is usually arranged outdoors and used to bring indoor heat to the outdoors.

[0068] refer to Figure 1 to Figure 3 In this embodiment, the air conditioner indoor unit includes a housing 1. The housing 1 is installed indoors, and the housing 1 forms the overall appearance of the air conditioner indoor unit.

[0069] Continue to refer Figure 1 The housing 1 is roughly rectangular. The housing 1 has a top and a bottom, and the top and the bottom of the housing 1 are two opposite ends of the housing 1 in the height direction. The left side of the housing 1 and the right side of the housing 1 are two opposite sides of the housing 1 in the length direction, and the front side of the housing 1 and the rear side of the housing 1 are two opposite sides of the housing 1 in the thickness direction.

[0070] The shell 1 is arranged on the top of the room or in the upper space of the room, the front side of the shell 1 is arranged toward the user, and the rear side of the shell 1 is arranged toward the wall, suitable for being connected to the wall.

[0071] It should be noted that the direction described in the article is based on the direction in which the user faces the air-conditioning indoor unit, wherein the side of the air-conditioning indoor unit facing the user when in use is defined as the front side, the opposite side is defined as the rear side, and the left and right sides are distinguished based on the direction in which the user faces the air-conditioning indoor unit.

[0072] refer to Figure 3 In some embodiments of the present application, the housing 1 may include a base 11. The base 11 forms the rear side of the air conditioner indoor unit 100, and the base 11 is suitable for being hung on a wall.

[0073] refer to Figure 5 The housing 1 may include an outer cover 12. The outer cover 12 is disposed on the base 11, and a heat exchange chamber 18 is formed between the outer cover 12 and the base 11.

[0074] The heat exchange chamber 18 is used to accommodate and fix various components in the air-conditioning indoor unit 100, which can prevent foreign objects from colliding with the various components in the shell 1, thereby improving the reliability of the air-conditioning indoor unit 100 during transportation or installation.

[0075] The outer cover 12 is roughly in the shape of a rectangular parallelepiped frame. The rear side of the outer cover 12 is open, and the outer cover 12 is arranged on the front side of the base 11 and connected with the base 11 to form the housing 1.

[0076] In some embodiments of the present application, the housing 1 may include an air-conditioning air inlet 13 .

[0077] The air-conditioning air inlet 13 is in communication with the heat exchange chamber 18 , and serves as an inlet for the external air to flow into the housing 1 , allowing the indoor air to enter the heat exchange chamber 18 through the air-conditioning air inlet 13 .

[0078] In some embodiments of the present application, the housing 1 may include an air-conditioning outlet 14 .

[0079] The air conditioning outlet 14 is in communication with the heat exchange cavity 18 , and serves as an outlet for the air flow in the shell 1 , allowing the air flow in the heat exchange cavity 18 to flow out through the air conditioning outlet 14 .

[0080] Among them, reference Figure 4 , Figure 5 The air inlet 13 of the air conditioner can be opened at the top of the outer cover 12. The air outlet 14 of the air conditioner can be opened at the front side of the outer cover 12 and arranged close to the bottom of the outer cover 13, that is, the air outlet 14 of the air conditioner is located at the bottom of the front side of the outer cover 12. In this embodiment, when the air conditioner indoor unit is working, the air conditioner indoor unit 100 takes in air from the upper side and discharges air toward the front side, which is convenient for arrangement.

[0081] The air-conditioning outlet 14 may be in a long strip shape, and the air-conditioning outlet 14 may be extended along the length direction of the housing 1 , thereby improving the aesthetics of the air-conditioning indoor unit 100 .

[0082] In some embodiments of the present application, reference Figure 6 The air conditioner indoor unit 100 may include an indoor heat exchanger 2. The indoor heat exchanger 2 extends along the length direction of the housing 1, and the indoor heat exchanger 2 is arranged in the heat exchange cavity 18 for performing heat exchange with the indoor air in the heat exchange cavity 18.

[0083] In some embodiments of the present application, the air-conditioning indoor unit 100 may include a heat exchange fan 3. The heat exchange fan 3 is a cross-flow fan.

[0084] The heat exchange fan 3 is arranged in the heat exchange chamber 18, and the axial direction of the heat exchange fan 3 extends along the length direction of the shell 1, and is used to drive the indoor air outside the shell 1 to enter the heat exchange chamber 18 in the shell 1 through the air inlet. The heat exchange fan 3 drives the air in the heat exchange chamber 18 to flow along the air-conditioning inlet 13 toward the air-conditioning outlet 14.

[0085] Continue to refer Figure 6 The indoor heat exchanger 2 and the heat exchange fan are both installed on the base 11, and the heat exchange fan 3 is arranged below the indoor heat exchanger 2.

[0086] The indoor heat exchanger 2 may be located inside the air conditioning inlet 13. The heat exchange fan 3 may be located on a side of the indoor heat exchanger 2 away from the air conditioning inlet 13. That is, in the airflow direction in the housing 1, the heat exchange fan 3 is located downstream relative to the indoor heat exchanger 2.

[0087] When the air-conditioning indoor unit 100 is running, driven by the heat exchange fan 3, the indoor air enters the heat exchange chamber 18 through the air-conditioning air inlet 13, and the indoor air in the heat exchange chamber 18 flows through the indoor heat exchanger 2 for heat exchange. The heat exchange airflow (air-conditioning air) after heat exchange is discharged to the room through the air-conditioning air outlet 14, so that the air conditioner can cool and heat, play a role in regulating the indoor temperature to achieve a comfortable temperature for the user.

[0088] In some embodiments of the present application, the outer cover 12 may be provided in one piece. Of course, in some other embodiments, the outer cover 12 may be provided in separate pieces.

[0095] The air conditioner outdoor unit may include an outdoor heat exchanger. The outdoor heat exchanger may be arranged in an outdoor heat exchange air duct.

[0096] The air conditioner outdoor unit may include an outdoor fan. The outdoor fan may be arranged in an outdoor heat exchange air duct.

[0097] The rotation of the outdoor fan causes the outdoor air to enter the outdoor heat exchange duct from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor heat exchange duct from the outdoor air outlet.

[0098] The air conditioner may include a compressor, which is arranged in an outdoor heat exchange air duct.

[0099] The air conditioner may include a throttling device. The throttling device is used for throttling. The throttling device may be provided in an indoor unit of the air conditioner or an outdoor unit of the air conditioner.

[0100] The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0101] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state, and the discharged refrigerant gas flows into the condenser.

[0102] The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0103] The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0104] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0105] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0106] Of the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0107] Continue to refer Figure 2 , Figure 6 An air outlet duct 17 is formed on the base 11. The air outlet duct 101 connects the heat exchange chamber 18 with the air outlet 14 of the air conditioner. The heat exchange airflow in the heat exchange chamber 18 enters the air outlet duct 17 under the action of the heat exchange fan 3, and flows to the air outlet 14 of the air conditioner through the air outlet duct 17, and finally flows into the room from the air outlet 14 of the air conditioner.

[0108] In some embodiments of the present application, reference Figure 7 to Figure 9 The wall mounted air conditioner may include a wind sweeping assembly 4. The wind sweeping assembly 4 is disposed on the base 11, and the wind sweeping assembly 4 is located in the air outlet duct 17 to adjust the wind direction in the air outlet duct 17.

[0109] The wind sweeping assembly 4 may include a plurality of wind sweeping blades, wherein the wind sweeping blades may be swingably arranged on the base 11 along the length direction of the housing, and the wind sweeping blades are located in the air outlet duct 17 to achieve left and right swing wind sweeping.

[0110] In some embodiments of the present application, reference Figure 8 The hanging air conditioner may include a recessed portion 5. The recessed portion 5 is formed on the base 11.

[0111] In some embodiments of the present application, the base 11 has a base front side and a base back side. The base front side is the side of the base facing the outer cover, that is, the base front side is closer to the outer cover than the base back side.

[0112] refer to Figure 8 The recessed portion 5 is formed by a portion of the front side of the base being recessed toward the back side of the base. This arrangement allows the wind sweeping motor 8 to be embedded inside the housing, thereby avoiding increasing the length of the entire machine.

[0113] refer to Fig. 9 A mounting cavity 19 is formed between the recessed portion 5 and the outer cover 12. The mounting cavity 19 is used to mount the wind sweeping motor 8. In this embodiment, the mounting cavity 19 and the heat exchange cavity 18 are independent of each other.

[0114] The base 11 is provided with a mounting portion, and the wind sweeping motor 8 is fastened and mounted on the mounting portion by fasteners. In this embodiment, the mounting portion can be a mounting column with a threaded hole, and the wind sweeping motor 8 is fixedly mounted on the mounting column by mounting bolts, which is simple and easy to operate.

It can be understood that the shaft sleeve 7 has a shaft hole, and the driving shaft 81 of the wind sweeping motor 8 is fixedly sleeved in the shaft hole to drive the wind sweeping motor 8 and the wind sweeping assembly 4.

[0121] In this embodiment, the wind sweeping motor 8 is installed in the installation cavity 19, so that the wind sweeping motor 8 is embedded in the shell, avoiding the wind sweeping motor 8 and the connection between the drive shaft 81 and the sleeve 7 from being exposed to the outside, thereby improving the aesthetics of the whole machine and preventing it from being affected by dust and foreign matter and causing obstruction to the movement of the wind sweeping component 4.

[0122] In some embodiments of the present application, the wall mounted air conditioner may include at least one heat dissipation hole 9. The at least one heat dissipation hole 9 is provided on the recessed portion 5 to connect the installation cavity 19 with the indoor environment.

[0123] By providing the heat dissipation holes 9 , indoor air in the indoor environment can enter the installation cavity 19 through the heat dissipation holes 9 , thereby achieving heat dissipation of the air sweeping motor 8 .

[0124] Specifically, in this embodiment, when the wall-mounted air conditioner is working and the sweeping blades sweep and swing left and right, air is blown at high speed from the air outlet duct 17 to the outside, i.e., in the direction of the air outlet 14 of the air conditioner, so that the air outlet duct 17 is in negative pressure, and the installation cavity 19 area is in high pressure relative to the air outlet duct 17. According to fluid theory, the high pressure near the sweeping motor 8 will flow to the low pressure.

[0125] Due to the clearance between the sleeve 7 and the through hole 6, affected by the pressure difference, the wind near the wind sweeping motor 8 will flow to the air outlet duct 17 through the clearance between the sleeve 7 and the through hole 6, and can be blown out together with the air conditioning wind. In this embodiment, by providing the heat dissipation hole 9, the indoor air can flow into the installation cavity 19 through the heat dissipation hole 9, thereby forming a loop. Fig.12 , Fig.12 The red solid line depicted in the figure is used to represent the flow path of the airflow in the loop, and the arrows attached to the red solid line are used to represent the flow direction of the airflow in the loop.

[0126] After the indoor air enters the installation cavity 19 through the heat dissipation hole 9, it will flow through the sweeping motor 8. After the flow of the indoor air takes away the heat generated by the sweeping motor 8, it will flow into the air outlet duct 17, thereby improving the heat dissipation effect of the sweeping motor 8 and avoiding the risk of failure of the sweeping motor 8 caused by the heat of the sweeping motor 8 in the installation cavity 19 not being dissipated in time after long-term operation.

[0127] In this embodiment, as long as the indoor unit of the wall-mounted air conditioner is running, there is an air flow pressure difference, which can realize air flow movement and then realize the heat dissipation of the air sweeping motor 8. The structure is simple and convenient and efficient.

[0128] In some embodiments of the present application, reference Figure 8 The recessed portion 5 is formed on the front side of the base 11. The front side of the base 11 is the side of the base facing the air outlet 14 of the air conditioner.

[0129] By forming the recessed portion 5 on the front side of the base 11, the recessed portion 5 and the front outer cover 12 form a mounting cavity 19. Compared with the prior art solution in which the air sweeping motor 8 is mounted on both sides of the air outlet 14 of the air conditioner, the size of the air conditioner indoor unit is saved, and the structural space is saved.

[0130] In some embodiments of the present application, the area where the wind sweeping motor 8 is projected on the recessed portion 5 is the projection area, and the heat dissipation hole 9 is located in the projection area.

[0131] In this embodiment, the projection of the wind sweeping motor 8 on the recessed portion 5 is defined as a projection area. By arranging the heat dissipation holes 9 in the projection area, the flowing airflow will penetrate the body of the wind sweeping motor 8, thereby more effectively improving the heat dissipation efficiency.

[0132] refer to Figure 15 to Figure 17 , which is a structural diagram of the wind sweeping component 4 in an illustrative embodiment of a wall-mounted air conditioner.

[0133] Specifically, refer to Figure 15 to Figure 17 The wind sweeping component 4 may include a base 41. The base 41 is installed on the base 11.

[0134] The wind sweeping blade may include a plurality of driven blades 43. The plurality of driven blades 43 are integrally formed on the base 41, and the plurality of driven blades 43 are distributed on the base 41 at intervals.

[0135] The wind sweeping blade may include an active blade 41. The active blade 41 is fixedly connected to the shaft sleeve 7, and the driving shaft 81 of the wind sweeping motor 8 rotates to drive the active blade 41 to rotate synchronously.

[0136] The wind sweeping assembly 4 may include a connecting rod 44. The connecting rod 44 is integrally formed on the plurality of driven blades 43, and one end of the connecting rod 44 is rotatably connected to the active blade 41. This arrangement enables the active blade 41 to rotate and drive the connecting rod 44 to move.

[0137] In this embodiment, the plurality of driven blades 43 are integrally formed on the base 41, so that the plurality of driven blades 43 and the base 41 form a whole, which is convenient for the installation of the wind sweeping assembly 4. In addition, the connecting rod 44 is integrally formed on the plurality of driven blades 43, so that the base 41, the plurality of driven blades 43 and the connecting rod 44 form an integrated structure, and the number of installed parts can be reduced, so that the assembly of the wind sweeping assembly 4 can be more convenient, the assembly efficiency can be improved, and of course, the overall manufacturing cost of the driven blades 43 can be reduced to a certain extent.

[0138] The driven blade 43 is a deformable blade structure. Specifically, the driven blade 43 includes a deformation portion 431. When the connecting rod 44 moves, the wind guide blade moves with the connecting rod 44 through the deformation of the deformation portion 431. When the connecting rod 44 swings left and right, the driven blade 43 can swing left and right with the connecting rod 44 through the deformation of the deformation portion 431, so that the left and right wind sweeping effect of the driven blade 43 can be achieved.

[0139] In this embodiment, the wind sweeping assembly 4 includes a base 41, driven blades 43, a connecting rod 44 and an active blade 41. When the wind sweeping motor 8 drives the active blade 41 to rotate, the connecting rod 44 is driven to operate, thereby driving the driven blade 43 to swing left and right.

[0140] Of course, in some other embodiments, the wind sweeping component 4 may be other structures in the prior art, and the specific structure of the wind sweeping component 4 is not limited here.

[0141] In order to allow the shaft sleeve 7 to be rotatably disposed in the through hole 6 , it can be understood that there is a clearance fit between the shaft sleeve 7 and the through hole 6 .

[0142] In some other embodiments of the present application, in the radial direction of the sleeve 7, the single-sided gap between the through hole 6 and the sleeve 7 is b, and b>0.

[0143] The unilateral gap b cannot be too small. If it is too small, the clearance fit between the two cannot be guaranteed, and the airflow in the installation cavity 19 cannot enter the air outlet duct 17 to achieve the heat dissipation function. In order to ensure clearance fit and ventilation and heat dissipation, the unilateral gap should be a first parameter value greater than 0. For example, the first parameter value can be 0.1mm, 0.15mm, or 0.2mm. Consider selecting a suitable and specific parameter in the specific design.

[0144] In some other embodiments of the present application, in the radial direction of the sleeve 7, the single-side gap between the through hole 6 and the sleeve 7 does not exceed 1 mm.

[0145] The unilateral gap b cannot be too large. In this embodiment, the wind sweeping motor 8 is connected to the active blade 41 through the shaft sleeve 7. If the unilateral gap b is too large, the stability of the active blade 41 will deteriorate. At the same time, too much indoor air will enter the air outlet duct 17 without passing through the indoor heat exchanger 2 for heat exchange, affecting the cooling and heating performance. In order to improve the structural stability, the unilateral gap b should not exceed the second parameter value. For example, the second parameter value can be 1mm, 0.95mm, or 0.9mm. Consider selecting a suitable and specific parameter in the specific design.

[0146] In some embodiments of the present application, the diameter of the heat dissipation hole 9 is a. a≤15 mm.

[0147] The diameter a of the heat dissipation hole 9 cannot be too large, otherwise it will affect the structural strength of the recessed portion 5 and the base 11. In order to ensure the structural strength, the diameter a of the heat dissipation hole 9 is set not to exceed the third parameter value. For example, the third parameter value can be 15mm, 14mm, or 13mm. Consider selecting a suitable specific parameter in the specific design.

[0148] In some embodiments of the present application, the diameter of the heat dissipation hole 9 is a. a≥1 mm.

[0149] The diameter a of the heat dissipation hole 9 cannot be too small, otherwise it will be inconvenient to process. In order to facilitate the processing of the heat dissipation hole 9, the diameter a of the heat dissipation hole 9 is set to be not less than the fourth parameter value. For example, the fourth parameter value can be 1 mm, 1.5 mm, or 2 mm. Consider selecting a suitable and specific parameter in the specific design.

[0150] In some embodiments of the present application, the diameter of the heat dissipation hole 9 is a. 1mm≤a≤15mm.

[0151] By setting the diameter of the heat dissipation hole 9 to any value between 1 and 15 mm, the processing and forming of the heat dissipation hole 9 is facilitated while ensuring the structural strength of the recessed portion 5 and the base 11 .

[0152] In some embodiments of the present application, the diameter of the heat dissipation hole is a. a≥1mm. a≤7mm; by setting the diameter of the heat dissipation hole to any value between 1mm and 7mm, the heat dissipation hole is prevented from being too small, the processing of the heat dissipation hole is facilitated, and sufficient structural strength of the base and the recessed portion is ensured.

[0153] In some embodiments of the present application, the diameter of the heat dissipation hole is a. a>7mm. a≤15mm. Setting the diameter of the heat dissipation hole to any value between 7mm and 15mm increases the ventilation volume while preventing the diameter of the heat dissipation hole from being too large to affect the structural strength of the base.

[0154] In some embodiments of the present application, reference Fig.18 , Fig.19 The base 11 may include a volute tongue 111. The volute tongue 111 forms an upper wall of the air outlet duct 17.

[0155] The base 11 may include a volute 112. The volute 112 forms a lower wall of the air duct 17. That is, the air duct 17 is formed between the volute tongue 111 and the volute 112.

[0156] The recessed portion 5 is located below the volute 112. Fig.19 The installation cavity 19 and the air outlet duct 17 are separated by the volute 112 .

[0157] In this embodiment, the through hole 6 is provided in the volute 112, and the wind sweeping assembly 4 is provided on the volute 112. By providing the recessed portion 5 below the volute 112, it is ensured that the wind sweeping motor 8 has sufficient installation space. Among them, the installation portion for installing the motor can also be provided on the volute 112.

[0158] In some embodiments of the present application, reference Fig.17 , Fig. 20 The wall mounted air conditioner may include a first stopper 71. The first stopper 71 is convexly disposed on the outer peripheral wall of the shaft sleeve 7.

[0159] The wall mounted air conditioner may include a second stopper 72. The second stopper 72 is convexly disposed on the outer peripheral wall of the sleeve 7. The first stopper 71 and the second stopper 72 are spaced apart in the axial direction of the sleeve 7.

[0160] The first stopper 71 and the second stopper 72 are convexly arranged on the outer peripheral wall of the sleeve 7 at intervals, so as to limit the sleeve 7 from escaping from the through hole 6 along its axial direction, thereby improving the connection stability of the sleeve 7 and the wind sweeping assembly 4. With this arrangement, when the wind sweeping motor 8 is disassembled or repaired, the sleeve 7 can be installed in the through hole 6, and the wind sweeping assembly 4 can be stably connected to the base 11, thereby improving the connection stability of each component.

[0161] In some embodiments of the present application, the second stopper 72 is located in the mounting cavity 19. Fig.17 , two second stoppers 72 are provided. The two second stoppers 72 are spaced apart along the outer circumference of the shaft sleeve 7 .

[0162] The two second stoppers 72 arranged at intervals can effectively limit the shaft sleeve 7 while preventing the airflow in the installation cavity 19 from entering the through hole 6 and affecting the heat dissipation effect.

[0163] In some embodiments of the present application, a limiting portion 10 is provided on the volute 112 .

[0164] refer to Fig.19 , Fig. 20 The limiting portion 10 is arranged around the edge of the through hole 6 facing the air outlet 14 of the air conditioner. The first stopper 71 is arranged on the side of the limiting portion 10 away from the volute 112, and the first stopper 71 is spaced apart from the limiting portion 10. In this embodiment, by spaced apart from the first stopper 71 and the limiting portion 10, the limiting portion 10 is prevented from interfering with the rotation of the shaft sleeve 7.

[0165] Continue to refer Fig.19 , a plurality of channels 101 are arranged at intervals on the limiting part 10. Among them, the channel 101 connects the through hole 6 and the channel 101 of the air outlet duct 17. This arrangement allows the airflow in the installation cavity 19 to flow out toward the air outlet 14 through the through hole 6 and the channel 101 in sequence, and is mixed with the air conditioning wind and blown out from the air outlet 14.

[0166] The wall-mounted air conditioner provided by the utility model embeds the sweeping motor 8 in the shell to avoid the sweeping motor 8 being exposed to the outside, thereby improving the aesthetics of the whole machine. At the same time, when the wall-mounted air conditioner is working and the sweeping blades are swept and swung left and right, the air outlet duct 17 blows air at high speed toward the air outlet 14 of the air conditioner. At this time, the air outlet duct 17 is under negative pressure, and the installation cavity 19 area is relatively under high pressure. Therefore, affected by the pressure difference, the wind near the sweeping motor 8 will flow to the air outlet duct 17 through the gap between the shaft sleeve 7 and the through hole 6. By providing the heat dissipation holes 9, the indoor air can flow into the installation cavity 19 through the heat dissipation holes 9, thereby forming a loop. The flow of indoor air will take away the heat generated by the sweeping motor 8, thereby improving the heat dissipation effect of the sweeping motor 8, and has the advantages of saving structural space, not increasing costs, and convenient and efficient heat dissipation.
