[0002] The wall-mounted air conditioner indoor unit includes a main body, with the height extending from top to bottom and the length extending from left to right. A first cavity is formed within the main body. The main body includes a housing, a heat exchange inlet and a heat exchange outlet communicating with the indoor air. A heat exchange fan is disposed within the housing and is used to draw indoor air into the housing through the heat exchange inlet and flow it into the indoor air through the heat exchange outlet. A drive motor is connected to the heat exchange fan to drive its rotation.

[0003] When the drive motor is configured as an outer rotor motor, it consists of an outer rotor component and an inner stator component. The outer rotor component is fixed to the heat exchange fan, and the inner stator component is fixed to the base.

DETAILED DESCRIPTION

[0086] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0087] This embodiment provides a wall mounted air conditioner indoor unit. Figures 1-19 Describe the indoor unit of a wall-mounted air conditioner.

[0088] The wall-mounted air conditioner indoor unit is a component of the air conditioner, which also includes an air conditioner outdoor unit.

[0089] See also Figure 1-Figure 5 The air conditioner 1000 may include a wall-mounted indoor air conditioner unit 100 and an outdoor air conditioner unit 200. The wall-mounted indoor air conditioner unit 100 is installed in an indoor space. The outdoor air conditioner unit 200 is installed in an outdoor space for exchanging heat with an outdoor environment.

[0090] The wall-mounted air conditioner indoor unit 100 includes a main body 300, which has a bottom and a top. The height of the main body 300 is from the bottom to the top of the main body 300. The main body 300 also has a length, where the length of the main body 300 is from one side to the other side in the left-right direction. The main body 300 has a front side and a rear side that are oppositely disposed. The side of the main body 300 facing the user is the front side of the main body 300, and the front-to-back direction of the main body 300 is from the front side to the rear side of the main body 300.

[0091] 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 opposite to each other, wherein a side of the housing 3 facing a user is the front side of the housing 3 .

[0092] The main body 300 may include a heat exchange air inlet 31, which is disposed on 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.

[0093] 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 .

[0094] The main body 300 may include a heat exchange outlet 32 ​​disposed at the bottom of the housing 3. The first chamber is connected to the heat exchange inlet 31 and the heat exchange outlet 32. During cooling or heating, indoor air flows into the first chamber through the heat exchange inlet 31 and then into the room through the heat exchange outlet 32.

[0095] The main body 300 may include an indoor heat exchanger 1001 . The indoor heat exchanger 1001 is disposed in the first cavity. The indoor heat exchanger 1001 is configured to exchange heat with the indoor air entering the first cavity.

[0096] 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 therein.

[0097] In some embodiments, the main body 300 may include a heat exchange fan 5, which is disposed within the heat exchange air duct 41. The axial direction of the heat exchange fan 5 is aligned with the longitudinal direction of the main body 300. As the heat exchange fan 5 operates, indoor air is introduced into the first chamber through the heat exchange air inlet, then flows through the indoor heat exchanger 1001, through the heat exchange air duct 41, and finally through the heat exchange air outlet 32 ​​to the indoor room.

[0098] 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.

[0099] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space and includes a housing having a second cavity disposed therein, and an outdoor air inlet and an outdoor air outlet disposed on the housing. The outdoor air inlet communicates with the outdoor space and the second cavity, and the outdoor air outlet communicates with the outdoor space and the second cavity.

[0100] In some embodiments, an outdoor heat exchanger 202 is provided 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.

[0101] In some embodiments, a compressor 201 is disposed in the shell, the compressor 201 is disposed in the second cavity, and the compressor 201 is installed at the bottom of the air-conditioning outdoor unit 200 .

[0102] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is arranged 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 can be arranged on the leeward side of the outdoor heat exchanger 202, which can be easily connected to the compressor 201.

[0103] 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.

[0104] The compressor 201 compresses the low-temperature, low-pressure refrigerant gas and discharges the high-temperature, high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0105] 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.

[0106] 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.

[0107] 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 .

[0108] 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.

[0109] 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 functions as a condenser and the outdoor heat exchanger 202 functions as an evaporator, the air conditioner 1000 functions as a heater in the heating mode. When the indoor heat exchanger 1001 functions as an evaporator and the outdoor heat exchanger 202 functions as a condenser, the air conditioner 1000 functions as a cooler in the cooling mode.

[0110] See also Figure 4-Figure 15 In some embodiments, the main body 300 may include a drive motor 6 , which is disposed at the first end 51 of the heat exchange fan 5 , and the drive motor 6 is used to drive the heat exchange fan 5 to rotate.

[0111] In some embodiments, the driving motor 6 may include a motor housing 61 , which is fixedly connected to the base 4 .

[0112] In some embodiments, the drive motor 6 may include an outer rotor 62, which is fixedly connected to the heat exchange fan 5. The rotation axis of the outer rotor 62 is coaxially arranged with the rotation axis of the heat exchange fan 5, and the outer rotor 62 rotates synchronously with the heat exchange fan 5.

[0113] In some embodiments, the driving motor 6 may include an inner stator 63 , which is disposed inside the outer rotor 62 , and the outer rotor 62 may rotate relative to the inner stator 63 .

[0114] The inner stator component 63 is detachably connected to the motor housing 61 . The motor housing 61 is connected to the base 4 . The inner stator component 63 is connected to the motor housing 61 to fix the inner stator component 63 .

[0115] In some embodiments, an assembly cavity 64 is provided inside the inner stator component 63 , and the assembly cavity 64 is configured as a through cavity that passes through the inner stator component 63 along the length direction of the main body.

[0116] In some embodiments, the main body may include a first bearing 7 disposed in the assembly cavity 64 .

[0117] In some embodiments, the first bearing 7 may include a sleeve 71 , which cooperates with the assembly cavity 64 to confine the first bearing 7 within the assembly cavity 64 .

[0118] The end of the sleeve 71 away from the heat exchange fan 5 is a closed end 711, and the end of the sleeve 71 close to the heat exchange fan 5 is an open end 712, that is, in the length direction of the main body, the end of the sleeve 71 away from the heat exchange fan 5 is set to a closed structure.

[0119] In some embodiments, the first bearing 7 may include a sliding member 72 , which is disposed inside the sleeve 71 .

[0120] A fan shaft 56 is provided at the end of the heat exchange fan 5. The fan shaft 56 passes through the open end 712 and the sliding member 72. A gap is provided between the fan shaft 56 and the closed end 711. That is, when the heat exchange fan 5 rotates normally, the fan shaft 56 does not abut the closed end 711. This prevents the fan shaft 56 and the closed end 711 from contacting each other during normal rotation, thus preventing the fan shaft 56 and the closed end 711 from contacting each other and affecting the rotation. In addition, when the heat exchange fan 5 is dropped and moves along its axial direction, the fan shaft 56 can abut against the closed end 711. The closed end 711 can provide a buffering force for the fan shaft 56, preventing damage to the heat exchange fan 5 caused by impact. It can also prevent the heat exchange fan 5 from hitting the drive motor or the base, thereby damaging the drive motor and the base.

[0121] In some embodiments, the first bearing 7 is configured as a sliding rubber bearing. The rubber material can provide a better buffering effect for the heat exchange fan 5.

[0122] In some embodiments, the closed end 711 can prevent dust from entering the first bearing 7 , thereby preventing dust from damaging the first bearing 7 .

[0123] In some embodiments, the assembly cavity 64 may include a first assembly portion 641 . The first assembly portion 641 is disposed inside the assembly cavity 64 , and the first assembly portion 641 is recessed toward the center of the assembly cavity 64 .

[0124] In some embodiments, the shaft sleeve 71 may include a first matching portion 713 . The first matching portion 713 is protruding toward the periphery of the shaft sleeve 71 , and the first matching portion 713 abuts against the first assembly portion 641 .

[0125] The first assembly portion 641 is set as a concave cavity, and the first matching portion 713 is set as a flange. The first matching portion 713 is set close to the heat exchange fan 5 relative to the first assembly portion 641, so that when the first matching portion 713 moves in a direction away from the heat exchange fan 5, the first matching portion 713 can press the first assembly portion 641 to prevent the sleeve 71 from moving in a direction away from the heat exchange fan 5 to disengage from the assembly cavity 64.

[0126] In some embodiments, the assembly cavity 64 may include a second assembly portion 642 , which is provided at an opening of the assembly cavity 64 close to the heat exchange fan 5 , and is recessed toward the periphery of the assembly cavity 64 .

[0127] In some embodiments, the sleeve 71 includes a second fitting portion 714 , which is disposed at the open end 712 of the sleeve 71 and protrudes toward the periphery of the sleeve 71 . The second fitting portion 714 abuts against the second assembly portion 642 .

[0128] The second assembly portion 642 is set as a concave cavity, and the second matching portion 714 is set as a flange. The second matching portion 714 is set close to the heat exchange fan 5 relative to the second assembly portion 642, so that when the sleeve 71 moves in the direction away from the heat exchange fan 5, the second matching portion 714 can press the second assembly portion 642 to prevent the sleeve 71 from moving in the direction away from the heat exchange fan 5 to disengage from the assembly cavity 64.

[0129] In some embodiments, the drive motor may include a card plate 65, which is arranged at one end of the motor housing away from the heat exchange fan 5. The card plate 65 is detachably connected to the motor housing, and the inner stator component 63 is confined to the inner side of the card plate 65 and the motor housing.

[0130] In some embodiments, the motor housing 61 may include a limiting rib 612 , which is disposed at the bottom of the motor housing 61 .

[0131] In some embodiments, the base 4 may include a motor cavity 42 , which is disposed on one side of the heat exchange air duct 41 , and the drive motor 6 is disposed in the motor cavity 42 .

[0132] In some embodiments, the base 4 may include a first limiting member 43 , which is disposed in the motor cavity 42 . The first limiting member 43 cooperates with the limiting rib 612 to limit the axial movement of the motor housing 61 .

[0133] The first limiting member 43 can be set as a limiting groove, and the limiting rib 612 can be inserted into the limiting groove. 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.

[0134] In some embodiments, the heat exchange fan 5 may include a first flange 53, which is arranged at the first end 51 of the heat exchange fan 5, the first flange 53 is arranged around the edge of the heat exchange fan 5, and the first flange 53 extends along the axial direction of the heat exchange fan 5 toward the drive motor 6.

[0135] In some embodiments, the motor housing 61 may include a second flange 613 extending toward the heat exchange fan 5 along the length direction of the main body.

[0136] The second flange 613 is arranged on the inner side of the first flange 53. In the projection in 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 damage to the drive motor 6 caused by the entry of dust.

[0137] In some embodiments, the heat exchange fan 5 may include a fan body 55 , which is located in the heat exchange air duct. The fan body 55 is cylindrical, and the first flange 53 is connected to the axial end of the fan body 55 .

[0138] In some embodiments, the fan shaft 56 is disposed at the end of the fan body, and the fan shaft 56 passes through the first bearing 7 .

[0139] In some embodiments, the heat exchange fan 5 may include an anti-collision rib 57, which is arranged at one end of the fan body 55 close to the first bearing 7. The anti-collision rib 57 is arranged to protrude from the fan body 55 along the axial direction of the heat exchange fan 5. There is a distance 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. After the anti-collision rib contacts the first bearing 7, the first bearing 7 acts as a buffer for the anti-collision rib and the heat exchange fan 5, thereby preventing damage to the heat exchange fan 5 or the drive motor due to impact.

[0140] In some embodiments, the fan shaft 56 is provided through the first bearing 7, and the fan shaft 56 can rotate relative to the first bearing 7. The first bearing 7 can limit the fan shaft 56 to rotate around the same rotation axis.

[0141] In some embodiments, the wall-mounted air conditioner indoor unit may further include a second bearing connected to the second axial end 58 of the heat exchange fan 5. The second bearing is disposed opposite the first bearing 7 in the axial direction of the heat exchange fan 5, and the fan shaft 56 passes through the second bearing. The first bearing 7 and the second bearing define the center of rotation of the heat exchange fan 5, preventing radial shaking of the heat exchange fan 5 during rotation.

[0142] In some embodiments, the inner stator component 63 may include a bracket 631 . The bracket 631 may be configured as an iron core. The bracket 631 is disposed inside the annular portion enclosed by the outer rotor component 62 .

[0143] In some embodiments, the inner stator 63 may include a coil, which may be a copper or aluminum coil. The coil is wound around a bracket 631, and current is applied to the coil to induce magnetism in the bracket 631. When the drive motor 6 is energized, current flows through the coil around the bracket 631, generating an induced magnetic field, which imparts magnetism to the bracket 631. This induced magnetic field interacts with the magnetic field generated by the outer rotor 62, which is configured as a permanent magnet, causing the outer rotor 62 to rotate relative to the inner stator 63. This rotation of the outer rotor 62 in turn drives the heat exchange fan 5 to rotate synchronously.
