[0001] The present application relates to the technical field of air conditioners, and in particular to a wall-mounted air conditioner indoor unit. Background Art

[0002] The indoor unit of the wall-mounted air conditioner includes a main body, the height direction of the main body is from the top to the bottom, the length direction of the main body is from the left to the right, and a first cavity is formed in the main body. The main body includes a casing, a heat exchange air inlet and a heat exchange air outlet connected to the indoor room. A heat exchange fan is arranged inside the casing, and the heat exchange fan is used to introduce indoor air into the casing through the heat exchange air inlet and flow into the indoor room through the heat exchange air outlet. A drive motor is connected to the heat exchange fan to drive the heat exchange fan to rotate.

[0003] The outside of the drive motor is usually provided with a motor cover to catch and guide the condensed water generated on the condenser tube of the indoor heat exchanger. When the condensed water continuously flows onto the motor cover, the temperature of the motor cover decreases.

DETAILED DESCRIPTION

[0082] Some embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments provided by the present disclosure are within the scope of protection of the present disclosure.

[0083] This embodiment provides a wall mounted air conditioner indoor unit. Figure 1-Figure 12 Describe the indoor unit of the wall-mounted air conditioner.

[0084] 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.

[0085] See also Figure 1-Figure 10 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.

[0086] 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.

[0087] 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 .

[0088] 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.

[0089] 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 .

[0090] 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.

[0091] 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.

[0092] 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 .

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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 .

[0097] 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 .

[0098] 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.

[0099] 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.

[0100] 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 .

[0101] 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.

[0102] 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.

[0103] 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 .

[0104] 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.

[0105] 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.

[0106] In some embodiments, the main body 300 may include a refrigerant inlet pipe 1002 , which is connected to one side of the indoor heat exchanger 1001 , and the refrigerant may flow to the indoor heat exchanger 1001 through the refrigerant inlet pipe 1002 .

[0107] 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.

[0108] In some embodiments, the main body 300 may include a motor housing, which is fixedly connected to the base, and the driving motor may be disposed inside the motor housing.

[0109] 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.

[0110] 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 .

[0111] The inner stator component 63 is detachably connected to the motor housing. The motor housing is connected to the base 4 . The inner stator component 63 is connected to the motor housing to fix the inner stator component 63 .

[0112] In some embodiments, the motor cover 8 may include a guide portion 81, which is connected to the end of the indoor heat exchanger 1001, and at least part of the refrigerant inlet pipe 1002 is arranged on the top of the guide portion 81. The guide portion 81 can be used to guide condensed water.

[0113] During cooling, the temperature of the refrigerant in the refrigerant inlet pipe is relatively low, so that the hot and humid air in the casing will produce condensation when it encounters the refrigerant inlet pipe, and the accumulated condensation will drip on the outer wall of the refrigerant inlet pipe.

[0114] The motor cover 8 can prevent the condensed water generated on the condensation pipe of the indoor heat exchanger from dripping onto the driving motor, and the guide part 81 can catch and guide the dripping condensed water.

[0115] In some embodiments, the guide portion 81 may be disposed around the outside of the driving motor, and the guide portion 81 may be configured to be arc-shaped so as to guide the condensed water.

[0116] In some embodiments, the motor cover 8 may include a thermal insulation portion 82 , which is disposed on the inner side of the air guide portion 81 . The thermal insulation portion 82 is disposed near the axis of the inner stator relative to the air guide portion 81 , and the drive motor is disposed on the inner side of the thermal insulation portion 82 .

[0117] An insulation cavity 83 is provided between the insulation portion 82 and the guide portion 81 . The insulation cavity 83 prevents the air inside the insulation portion 82 from contacting the guide portion 81 . The insulation cavity 83 can reduce the heat transfer efficiency between the surface of the guide portion 81 and the air inside the insulation cavity 83 .

[0118] When condensed water continuously flows to the guide part 81 of the motor outer cover 8, the temperature of the guide part 81 decreases, and the insulation cavity 83 can isolate the air inside the insulation part 82 from contacting the guide part 81, thereby reducing the heat transfer efficiency between the surface of the guide part 81 and the air inside the insulation cavity 83, avoiding the problem of condensed water generated by the air inside the insulation part 82 contacting the colder insulation part 82, thereby improving the reliability of the drive motor.

[0119] In some embodiments, the motor housing 8 may include a limiting rib 612 , and the limiting rib 612 is disposed at the bottom of the motor housing 8 .

[0120] 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 .

[0121] In some embodiments, the base 4 may include a first stopper 43, which is disposed in the motor cavity 42, and the first stopper 43 cooperates with the stopper rib 612 to limit the axial movement of the motor housing 8. The drive motor 6 is fixed in the motor housing 8, thereby limiting the axial movement of the drive motor 6.

[0122] 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 cover 8 in the length direction of the main body.

[0123] In some embodiments, the base 4 may include a first limit plate 44 , which is disposed at one end of the motor cavity 42 away from the heat exchange fan 5 , and the first limit plate 44 is connected to the motor cover 8 to be disposed on one side of the drive motor 6 .

[0124] In some embodiments, the first limit plate 44 is connected to the motor cover 8, and the drive motor 6 can be sealed on the inner side of the enclosed structure formed by the first limit plate 44 and the motor cover 8 in the length direction of the main body to prevent moisture and dust from entering the drive motor 6 through the gap, prevent dust from damaging the drive motor 6, and avoid moisture condensing in the drive motor 6 and damaging the drive motor 6.

[0125] In some embodiments, the base 4 may include a drainage portion 45 connected to the guide portion 81. In the height direction of the main body, the guide portion 81 is disposed above the drainage portion 45, and the guide portion 81 can guide the condensed water to the drainage portion 45.

[0126] In some embodiments, the base 4 may include a drainage hole 452 , which is disposed in the drainage portion 45 , and condensed water may be discharged from the housing through the drainage hole 452 .

[0127] At least part of the drainage portion 45 is disposed on a side of the first limiting plate 44 away from the drive motor 6 , and the first limiting plate 44 can be used to separate the condensed water from the drive motor 6 to prevent the condensed water from splashing into the drive motor 6 .

[0128] In some embodiments, the drainage portion 45 may include a first rib 451 . The first rib 451 may be configured to be plate-shaped. The first rib 451 extends toward the flow guide portion 81 .

[0129] In some embodiments, the motor cover 8 may include a second rib 84, which is connected to the bottom of the guide portion 81 and extends toward the drain portion 45. The second rib 84 is arranged on the periphery of the first rib 451 to facilitate the diversion of condensed water on the guide portion 81 to the drain portion 45, thereby preventing the condensed water on the guide portion 81 from being diverted into the gap between the guide portion 81 and the drain portion 45, thereby preventing the condensed water from flowing into the drive motor 6.

[0130] The first rib 451 can prevent condensed water from splashing into the motor housing 8 , thereby preventing the condensed water from damaging the drive motor 6 .

[0131] In some embodiments, the height of the first retaining edge 451 is greater than the first height, which can prevent the condensed water from splashing outside the drainage portion 45. When the height of the first retaining edge 451 is less than or equal to the first height, the height of the first retaining edge 451 is small and cannot effectively block the splashing of the condensed water, so that the condensed water can splash into the motor housing 8 and damage the drive motor 6. Therefore, the height of the first baffle is greater than the first height, and the first height can be set to 20 mm.

[0132] In some embodiments, the motor housing 8 may include a first flange 85. In the length direction of the main body, the first flange 85 is provided at one end of the guide portion 81, the first flange 85 is connected to the outdoor heat exchanger, and the first flange 85 extends in a direction away from the drive motor 6. The motor housing 8 can be fixed to the indoor heat exchanger by the first flange 85, and the first flange 85 can block condensed water, and prevent condensed water from splashing on the guide portion 81. The splashed condensed water splashes onto the first flange 85, and can flow along the first flange 85 to the guide portion 81 again.

[0133] In some embodiments, the motor housing 8 may include a second flange 86, which is disposed at the other end of the guide portion 81, and the second flange 86 is disposed opposite to the first flange 85 in the length direction of the main body, and the second flange 86 extends in a direction away from the drive motor 6. The second flange 86 can block condensed water, and can prevent condensed water from splashing on the guide portion 81. The splashed condensed water splashes onto the second flange 86, and can flow along the second flange 86 to the guide portion 81 again, and then flow to the drainage portion 45 through the guide portion 81.

[0134] In some embodiments, the wall-mounted air conditioner indoor unit may include an electrical box connected to the base 4. The electrical box is arranged away from the heat exchange fan 5 relative to the drive motor 6, which can reasonably utilize the space in the length direction of the main body and improve space utilization.

[0135] In some embodiments, the first limit plate 44 is provided with a wiring opening 441, one end of the motor wire is connected to the drive motor 6, and the other end of the motor wire is passed through the wiring opening 441 to connect to the electrical box, and the drive motor 6 is controlled by the circuit board in the electrical box. The size of the wiring hole can be adjusted according to the diameter of the motor wire. If the size of the wiring opening 441 is too small, the wiring of the motor wire is difficult, which is not conducive to the assembly and connection of the motor wire. Therefore, the inner diameter of the wiring opening 441 is greater than 5 mm.

[0136] When the size of the wiring opening 441 is too large, the ability of the first limiting plate 44 to block air from entering the inner side of the motor housing 8 is reduced, and the blocking effect becomes worse, so the inner diameter of the wiring opening 441 is less than 20 mm.

[0137] In some embodiments, the heat exchange fan 5 may include a first end 51 , and the first end 51 is an axial end of the heat exchange fan 5 .

[0138] In some embodiments, the inner stator component 63 is detachably connected to the motor housing 8 , the motor housing 8 is connected to the base 4 , and the inner stator component 63 is connected to the motor housing 8 to achieve fixation of the inner stator component 63 .

[0139] In some embodiments, the main body may include a first bearing 7 , the first bearing 7 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 .

[0140] In some embodiments, the first bearing 7 may be configured as a sliding rubber bearing.

[0141] In some embodiments, the heat exchange fan 5 includes a fan shaft, the fan shaft is provided with a first bearing 7, and the fan shaft can rotate relative to the first bearing 7. The first bearing 7 can limit the fan shaft to rotate around the same rotation axis.

[0142] 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 passes through the second bearing. The first bearing 7 and the second bearing can define the rotation center of the heat exchange fan 5 to prevent the heat exchange fan 5 from shaking in the radial direction when rotating.

[0143] In some embodiments, the inner stator component 63 may include a bracket, which may be configured as an iron core, and the bracket is disposed inside the enclosed annular portion of the outer rotor component 62 .

[0144] In some embodiments, the inner stator member 63 may include a coil, which may be a copper coil or an aluminum coil. 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.

[0145] 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.

[0146] , see Figure 11-Figure 12 In some embodiments, the driving motor 6 may include a motor housing 61 , which is fixedly connected to the base 4 , and the motor housing 61 is disposed inside the motor cover 8 , and the motor cover 8 covers the motor housing 61 .

[0147] The motor cover 8 can be used to guide condensed water. A temperature-insulating cavity 83 is provided between the motor cover 8 and the motor housing 61. The temperature-insulating cavity 83 prevents the air inside the motor housing 61 from contacting the motor cover 8, thereby reducing the heat transfer efficiency between the surface of the motor cover 8 and the air inside the motor housing 61, avoiding the problem of condensed water generated by the air inside the motor housing 61 contacting the cooler motor housing 61, and improving the reliability of the use of the drive motor 6.

[0148] In some embodiments, the motor cover 8 and the motor housing 61 are integrally formed to reduce parts and improve the assembly efficiency of components.
