[0079] This embodiment provides a wall mounted air conditioner indoor unit. Figure 1-Figure 12 Describe the indoor unit of the wall-mounted air conditioner.

[0080] The indoor unit of the wall-mounted air conditioner is a component of the air conditioner, wherein the air conditioner also includes the outdoor unit of the air conditioner.

[0081] See also Figure 1-Figure 12 The air conditioner 1000 may include a wall mounted air conditioner indoor unit 100 and an air conditioner outdoor unit 200. The wall mounted air conditioner indoor unit 100 is installed in an indoor space. The air conditioner outdoor unit 200 is installed in an outdoor space for heat exchange with an outdoor environment.

[0082] The wall-mounted air conditioner indoor unit 100 includes a main body 300, the main body 300 has a bottom and a top, the height direction of the main body 300 is from the bottom of the main body 300 to the top of the main body 300, and the main body 300 also has a length direction, wherein one side of the main body 300 in the left-right direction to the other side thereof is the length direction of the main body 300. The main body 300 has a front side and a rear side that are arranged oppositely, wherein the side of the main body 300 facing the user is the front side of the main body 300, and the front and rear direction of the main body 300 is from the front side of the main body 300 to the rear side of the main body 300.

[0083] The main body 300 may include a housing 3 , which is disposed in an indoor space. The housing 3 has a front side and a rear side that are oppositely disposed, wherein a side of the housing 3 facing a user is the front side of the housing 3 .

[0084] The main body 300 may include a heat exchange air inlet 31, which is disposed at the top of the housing 3. During cooling or heating, indoor air may enter the interior of the housing 3 through the heat exchange air inlet 31.

[0085] The main body 300 may include a first cavity formed inside the housing 3 . The first cavity is communicated with the heat exchange air inlet 31 , and indoor air may enter the first cavity through the heat exchange air inlet 31 .

[0086] The main body 300 may include a heat exchange outlet 32, which is disposed at the bottom of the housing 3, and the first cavity is respectively connected to the heat exchange inlet 31 and the heat exchange outlet 32. When cooling or heating, the indoor air flows into the first cavity through the heat exchange inlet 31 and flows into the room through the heat exchange outlet 32.

[0087] The main body 300 may include an indoor heat exchanger 1001 , which is disposed in the first cavity. The indoor heat exchanger 1001 is used to exchange heat with indoor air entering the first cavity.

[0088] In some embodiments, the main body 300 may include a base 4 , which is disposed in the first cavity and has a heat exchange air duct 41 formed in the base 4 .

[0089] In some embodiments, the main body 300 may include a heat exchange fan 5, which is disposed in the heat exchange air duct 41, and the axial direction of the heat exchange fan 5 is in the same direction as the length direction of the main body 300. Through the operation of the heat exchange fan 5, indoor air is introduced into the first cavity from the heat exchange air inlet, then flows through the indoor heat exchanger 1001, flows through the heat exchange air duct 41, and then flows into the room through the heat exchange air outlet 32.

[0090] It can be arranged that the heat exchange fan 5 is arranged on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to the air flow and increase the air intake into the room.

[0091] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space, and the air conditioner outdoor unit 200 includes a housing, a second cavity is disposed in the housing, and an outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is connected to the outdoor space and the second cavity, and the outdoor air outlet is connected to the outdoor space and the second cavity.

[0092] In some embodiments, an outdoor heat exchanger 202 is disposed in the shell, and refrigerant flows in the outdoor heat exchanger 202 . The refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air entering the second cavity and flowing through the outdoor heat exchanger 202 .

[0093] In some embodiments, a compressor 201 is disposed in the shell, the compressor 201 is disposed in the second chamber, and the compressor 201 is installed at the bottom of the air-conditioning outdoor unit 200 .

[0094] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, and may be conveniently connected to the compressor 201.

[0095] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204 and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0096] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0097] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0098] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0099] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0100] The indoor heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0101] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 is used as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 is used as a cooler in the cooling mode.

[0102] In some embodiments, the heat exchange fan 5 may include a first end 51 , which is an axial end of the heat exchange fan 5 . The first end 51 is provided with a first limiting portion 52 , and the first limiting portion 52 extends toward the axis of the heat exchange fan 5 .

[0103] In some embodiments, the main body 300 may include a driving motor 6 , which is disposed at the first end 51 of the heat exchange fan 5 , and the driving motor 6 is used to drive the heat exchange fan 5 to rotate.

[0104] In some embodiments, the driving motor 6 may include a motor housing 61 , which is fixedly connected to the base 4 , and a second limiting portion 611 is disposed at one end of the motor housing 61 .

[0105] In some embodiments, the driving motor 6 may include an outer rotor component 62, which is fixedly connected to the heat exchange fan 5, and the rotation axis of the outer rotor component 62 is coaxially arranged with the rotation axis of the heat exchange fan 5, and the outer rotor component 62 rotates synchronously with the heat exchange fan 5.

[0106] In some embodiments, the driving motor 6 may include an inner stator component 63 , which is disposed inside the motor housing 61 , and the outer rotor component 62 may rotate relative to the inner stator component 63 .

[0108] A gap is provided between the second limiting portion 611 and the first limiting portion 52. In the length direction of the main body 300, the first limiting portion 52 is arranged away from the heat exchange fan 5 relative to the second limiting portion 611. In the projection of the length direction of the main body 300, the first limiting portion 52 at least partially overlaps with the second limiting portion 611.

[0109] A distance is provided between the second limiting portion 611 and the first limiting portion 52 , so as to prevent the first limiting portion 52 from contacting the second limiting portion 611 and affecting the rotation of the heat exchange fan 5 when the heat exchange fan 5 rotates.

[0110] In the length direction of the main body 300, the first limit portion 52 is arranged away from the heat exchange fan 5 relative to the second limit portion 611. In the projection of the length direction of the main body 300, the first limit portion 52 and the second limit portion 611 at least partially overlap. That is, the second limit portion 611 is arranged between the first limit portion 52 and the heat exchange fan 5. When the heat exchange fan 5 is transported and dropped, causing the heat exchange fan 5 to move along its axial direction, the first limit portion 52 and the second limit portion 611 can abut against each other to limit the separation of the heat exchange fan 5 and the drive motor 6, avoid the separation of the drive motor 6 and the heat exchange fan 5, and improve the assembly efficiency of the heat exchange fan 5 and the drive motor 6.

[0111] A spacing is provided between the first limiting portion 52 and the second limiting portion 611. When the heat exchange fan 5 moves along its axial direction, the first limiting portion 52 and the second limiting portion 611 abut against each other. This can prevent the first limiting portion 52 and the second limiting portion 611 from contacting each other and affecting the rotation when the heat exchange fan 5 rotates normally. It can also prevent the drive motor 6 from being disconnected from the heat exchange fan 5 when the heat exchange fan 5 falls and moves along its axial direction, thereby preventing damage to the heat exchange fan 5 and the drive motor 6 and repeated assembly of the heat exchange fan 5 and the drive motor 6, thereby improving the assembly efficiency of the heat exchange fan 5 and the drive motor 6.

[0112] In some embodiments, the motor housing 61 may include a limiting rib 612 , and the limiting rib 612 is disposed at the bottom of the motor housing 61 .

The limiting groove is clamped on the limiting rib 612 to prevent the limiting rib 612 from moving along the axial direction of the heat exchange fan 5, and can limit the freedom of the motor housing 61 in the length direction of the main body 300.

[0116] In some embodiments, the heat exchange fan 5 may include a first flange 53, which is disposed at the first end 51 of the heat exchange fan 5, and the first flange 53 is disposed around the edge of the heat exchange fan 5.

[0119] The first limiting portion 52 is configured as a hook, and the first limiting portion 52 extends toward a direction close to the second flange 613 .

[0120] In the projection of the height direction of the main body 300 , the first flange 53 and the second flange 613 at least partially overlap, so that the first flange 53 and the second flange 613 can be staggered to prevent dust from falling into the interior of the motor housing 61 , thereby avoiding the loss of the drive motor 6 .

[0121] In some embodiments, the heat exchange fan 5 may include a third flange 54, which is arranged on the inner side of the first flange 53, and the third flange 54 extends along the axial direction of the heat exchange fan 5 to drive the motor 6, and the outer rotor component 62 is arranged on the inner side of the third flange 54, and the outer rotor component 62 rotates synchronously with the heat exchange fan 5.

[0122] In some embodiments, the third flange 54 is configured to be annular, the third flange 54 is coaxially configured with the first flange 53, the second flange 613 is configured between the first flange 53 and the third flange 54, the third flange 54 does not contact the first flange 53, and a gap is configured between the first flange 53, the second flange 613 and the third flange 54 to facilitate the rotation of the heat exchange fan 5.

[0123] Gaps and bends are provided between the first flange 53 , the second flange 613 and the third flange 54 , which can prevent dust and moisture from entering the interior of the motor housing 61 and avoid damaging the drive motor 6 .

[0124] In some embodiments, the main body 300 may include a first bearing 7 , which is disposed at the first end 51 of the heat exchange fan 5 , and the first bearing 7 is disposed inside the inner stator component 63 .

[0128] In the projection of the height direction of the main body 300, there is a distance between the fourth flange 614 and the first limiting portion 52, so that when the heat exchange fan 5 falls and moves along its axial direction, the first limiting portion 52 is prevented from hitting the fourth flange 614, thereby avoiding damage to the heat exchange fan 5 and the drive motor 6 components.

[0129] In some embodiments, the wall-mounted air conditioner indoor unit may further include a second bearing, which is connected to the second axial end 58 of the heat exchange fan 5. In the axial direction of the heat exchange fan 5, the second bearing is arranged opposite to the first bearing 7, and the fan shaft 56 passes through the second bearing.

The coil is wound around a bracket, and the coil is energized to make the bracket magnetic. When the drive motor 6 is energized, current flows through the coil wound around the bracket to generate an induced magnetic field, making the bracket magnetic. The induced magnetic field interacts with the magnetic field generated by the outer rotor member 62, which is set as a permanent magnet, so that the outer rotor member 62 rotates relative to the inner stator member 63, and the rotation of the outer rotor member 62 drives the heat exchange fan 5 to rotate synchronously.

[0132] In some embodiments, the inner stator 63 may include a covering portion, which wraps around the periphery of the bracket and the coil, and the covering portion is integrally formed with the bracket and the coil. When installing the inner stator 63, the bracket, the coil and the covering portion are assembled as a whole.

[0133] In some embodiments, the heat exchange fan 5 may include a fan body 55 , which is cylindrical in shape, and the first flange 53 and the second flange 613 are respectively connected to the axial ends of the fan body 55 .

[0134] In some embodiments, the heat exchange fan 5 may include an anti-collision rib 57, which is arranged at the axial end of the fan body 55. The anti-collision rib 57 is arranged to protrude from the fan body 55 along the axial direction of the heat exchange fan 5. A spacing is provided between the anti-collision rib 57 and the first bearing 7 so that the heat exchange fan 5 can run a certain distance relative to the first bearing 7 when it falls, thereby playing a buffering role and avoiding the interference of the first bearing 7 with the heat exchange fan 5 when the heat exchange fan 5 rotates normally.

[0135] In some embodiments, the first bearing 7 is configured as a sliding rubber bearing.

[0136] In some embodiments, the minimum spacing between the fourth flange 614 and the first limiting portion 52 is the first spacing s, and the minimum spacing between the anti-collision rib 57 and the first bearing 7 is b, wherein s>b, so that when the heat exchange fan 5 slides along its axial direction due to falling, the anti-collision rib 57 can impact and contact the first bearing 7, and the first bearing 7 made of rubber material can buffer the anti-collision rib 57, and then buffer the heat exchange fan 5, thereby preventing the fan from colliding with the inner stator component 63, thereby avoiding damage to the heat exchange fan 5.

[0137] s>b can ensure that when the anti-collision rib 57 collides with the first bearing 7, the first limiting portion 52 and the fourth flange 614 do not contact each other, thereby avoiding damage to the first limiting portion 52 and the fourth flange 614 caused by the collision, thereby avoiding damage to the heat exchange fan 5.

[0138] In some embodiments, the shortest distance between the fan body 55 and the inner stator component 63 is a, where a>b, so that the fan body 55 and the inner stator component 63 do not contact each other when the anti-collision rib 57 collides with the first bearing 7, thereby avoiding damage to the fan body 55 and the inner stator component 63 caused by the collision, thereby avoiding damage to the heat exchange fan 5 and the drive motor 6.

[0139] In some embodiments, the distance between the first limiting portion 52 and the second limiting portion 611 is n, where n>b, so that when the anti-collision rib 57 collides and contacts the first bearing 7, the first limiting portion 52 and the second limiting portion 611 do not contact each other, thereby avoiding damage to the first limiting portion 52 and the second limiting portion 611 caused by the collision, thereby avoiding damage to the heat exchange fan 5 and the drive motor 6.

[0140] In some embodiments, the minimum distance between the first limit portion 52 and the second flange 613 is f, where f>1mm, and the first limit portion 52 can prevent dust and moisture from entering the interior of the motor housing 61. When f≤1mm, the distance between the first limit portion 52 and the second flange 613 is too small, and when the heat exchange fan 5 rotates, the first limit portion 52 and the second flange 613 may interfere with each other and affect the rotation of the heat exchange fan 5. Therefore, f>1mm can prevent the first limit portion 52 from contacting the second flange 613 when the heat exchange fan 5 rotates, thereby preventing the heat exchange fan 5 from being damaged.

[0141] In some embodiments, the minimum distance between the second limit portion 611 and the first flange 53 is p, where p>1mm, and the second limit portion 611 can prevent dust and moisture from entering the interior of the motor housing 61. When p≤1mm, the distance between the second limit portion 611 and the first flange 53 is too small, and when the heat exchange fan 5 rotates, the second limit portion 611 and the first flange 53 may interfere with each other and affect the rotation of the heat exchange fan 5. Therefore, when p>1mm, the second limit portion 611 can be prevented from contacting the first flange 53 when the heat exchange fan 5 rotates, thereby preventing the heat exchange fan 5 from being damaged.
