Detailed implementation manners

[0076] The following will clearly and completely describe some embodiments of the present disclosure with reference to the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0077] This embodiment provides a wall-mounted air conditioner indoor unit, which will be described below with reference to Figures 1 - 13 the wall-mounted air conditioner indoor unit.

[0078] The wall-mounted air conditioner indoor unit is a component of the air conditioner. Among them, the air conditioner further includes an air conditioner outdoor unit.

[0079] See Figures 1 - 13 , 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 the indoor space. The air conditioner outdoor unit 200 is installed in the outdoor space for heat exchange with the outdoor environment.

[0080] The wall-mounted air conditioner indoor unit 100 includes a main body 300. The main body 300 has a bottom and a top. The direction from the bottom to the top of the main body 300 is the height direction of the main body 300. The main body 300 further has a length direction. Among them, the direction from one side part to the other side part of the main body 300 in the left-right direction is the length direction of the main body 300. The main body 300 has a front side and a rear side which are oppositely arranged. Among them, the side of the main body 300 facing the user is the front side of the main body 300. The direction from the front side to the rear side of the main body 300 is the front-rear direction of the main body 300.

[0081] The main body 300 may include a housing 3 disposed in an indoor space. The housing 3 has a front side and a rear side disposed opposite to each other, wherein the side of the housing 3 facing the user is the front side of the housing 3.

[0082] The main body 300 may include a heat exchange air inlet 31 disposed at the top of the housing 3. When cooling or heating, indoor air can enter the interior of the housing 3 through the heat exchange air inlet 31.

[0083] The main body 300 may include a first chamber formed inside the housing 3. The first chamber is in communication with the heat exchange air inlet 31, and indoor air can enter the first chamber through the heat exchange air inlet 31.

[0084] The main body 300 may include a heat exchange air outlet 32 disposed at the bottom of the housing 3. The first chamber is in communication with both the heat exchange air inlet 31 and the heat exchange air outlet 32. When cooling or heating, indoor air flows from the heat exchange air inlet 31 to the first chamber and then flows to the indoor through the heat exchange air outlet 32.

[0085] The main body 300 may include an indoor heat exchanger 1001 disposed in the first chamber. The indoor heat exchanger 1001 is used for heat exchange with the indoor air entering the first chamber.

[0086] In some embodiments, the main body 300 may include a base 4 disposed in the first chamber. A heat exchange air duct 41 is formed inside the base 4.

[0087] In some embodiments, the main body 300 may include a heat exchange fan 5 disposed in the heat exchange air duct 41. The axial direction of the heat exchange fan 5 is the same as the length direction of the main body 300. By operating the heat exchange fan 5, indoor air is introduced from the heat exchange air inlet into the first chamber, then flows through the indoor heat exchanger 1001, flows through the heat exchange air duct 41, and then flows to the indoor through the heat exchange air outlet 32.

[0088] It can be set that the heat exchange fan 5 is disposed on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to air flow and increase the air intake volume into the indoor.

[0089] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space. The air conditioner outdoor unit 200 includes a housing. A second chamber is disposed inside the housing. An outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is in communication with the outdoor space and the second chamber, and the outdoor air outlet is in communication with the outdoor space and the second chamber.

[0090] In some embodiments, an outdoor heat exchanger 202 is disposed inside the housing. A refrigerant flows through the outdoor heat exchanger 202. The refrigerant in the outdoor heat exchanger 202 can be used for heat exchange with the air entering the second chamber and flowing through the outdoor heat exchanger 202.

[0091] In some embodiments, a compressor 201 is disposed inside the housing. The compressor 201 is located in the second chamber and is installed at the bottom of the air conditioner outdoor unit 200.

[0092] In some embodiments, the air conditioner outdoor unit 200 may include a throttling device 204. The throttling device 204 is disposed in the second chamber 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, which is convenient for connection to the compressor 201.

[0093] The air conditioner 1000 performs the 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.

[0094] The compressor 201 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. The discharged refrigerant gas flows into the outdoor heat exchanger 202.

[0095] 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.

[0096] The throttling device 204 expands the liquid refrigerant in a high-temperature and high-pressure state condensed in the outdoor heat exchanger 202 into a low-pressure liquid refrigerant.

[0097] 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.

[0098] The indoor heat exchanger 1001 can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0099] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one of them 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 serves 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 serves as a cooler in the cooling mode.

[0100] See Figures 4 - 13 , in some embodiments, the main body 300 may include a driving motor 6. The driving motor 6 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.

[0101] In some embodiments, the drive motor 6 may include a motor housing 61, and the motor housing 61 is fixedly connected to the base 4.

[0102] In some embodiments, the drive motor 6 may include an outer rotor member 62, and the outer rotor member 62 is fixedly connected to the heat exchange fan 5. The rotation axis of the outer rotor member 62 is coaxially arranged with the rotation axis of the heat exchange fan 5, and the outer rotor member 62 rotates synchronously with the heat exchange fan 5.

[0103] In some embodiments, the drive motor 6 may include an inner stator member 63, and the inner stator member 63 is disposed inside the outer rotor member 62. The outer rotor member 62 is rotatable relative to the inner stator member 63.

[0104] The inner stator member 63 is detachably connected to the motor housing 61. The motor housing 61 is connected to the base 4, and the inner stator member 63 is connected to the motor housing 61 to fix the inner stator member 63.

[0105] In some embodiments, an assembly cavity 64 is provided inside the inner stator member 63, and the assembly cavity 64 is provided as a through cavity that penetrates the inner stator member 63 along the length direction of the main body.

[0106] In some embodiments, the main body may include a first bearing 7, and the first bearing 7 is disposed inside the assembly cavity 64.

[0107] The end of the heat exchange fan 5 is provided with a fan shaft 56. The fan shaft penetrates the first bearing 7 along the length direction of the main body, and the assembly cavity penetrates the inner stator member 63 in the length direction of the main body.

[0108] The assembly cavity 64 penetrates the inner stator member 63 in the length direction of the main body, so that the fan shaft does not contact the inner stator member 63 in the length direction of the main body, avoiding mutual contact between the fan shaft 56 and the inner stator member and affecting rotation. Also, when the heat exchange fan 5 is dropped and the heat exchange fan 5 moves axially, the fan shaft slides along the length direction of the main body in the assembly cavity, and the fan shaft 56 does not contact the inner stator member, preventing the heat exchange fan 5 shaft from hitting the inner stator member and causing damage to the heat exchange fan 5, and also preventing the heat exchange fan 5 from hitting the drive motor or the base and causing damage to the drive motor 6 and the base 4.

[0109] In some embodiments, there is a spacing between the end face of the inner stator member 63 away from the heat exchange fan 5 and the fan shaft 56. When the heat exchange fan 5 rotates normally, the fan shaft does not contact the inner stator member, enabling the fan to rotate normally. Also, when the heat exchange fan 5 is dropped and moves axially along its axis, the heat exchange fan can slide a certain distance within the spacing between the end face of the inner stator member and the fan shaft, preventing the fan shaft from contacting the inner stator member and preventing the fan shaft from hitting the inner stator member and damaging the heat exchange fan 5. It can also prevent the heat exchange fan 5 from hitting the drive motor or the base and damaging the drive motor and the base.

[0110] In some embodiments, the first bearing 7 may include a bushing 71, and the bushing 71 is fitted with the assembly cavity 64 to limit the first bearing 7 within the assembly cavity 64.

[0111] The two opposite ends of the bushing 71 are respectively provided as open ends 712. That is, in the length direction of the main body, the fan shaft passes through the open end of the bushing 71 close to the heat exchange fan 5 to connect the first bearing.

[0112] In some embodiments, the bushing 71 may penetrate or partially penetrate the open end 712 away from the heat exchange fan 5.

[0113] In some embodiments, the first bearing 7 may include a sliding member 72, and the sliding member 72 is disposed inside the bushing 71.

[0114] The fan shaft passes through the open end of the bushing 71 close to the heat exchange fan 5 and the sliding member, and the fan shaft can rotate relative to the sliding member.

[0115] In some embodiments, the first bearing 7 is provided as a sliding rubber bearing.

[0116] In some embodiments, the assembly cavity 64 may include a first assembly portion 641, and the first assembly portion 641 is disposed inside the assembly cavity 64 and is recessed toward the center of the assembly cavity 64.

[0117] In some embodiments, the bushing 71 may include a first mating portion 713, and the first mating portion 713 protrudes toward the periphery of the bushing 71, and the first mating portion 713 abuts against the first assembly portion 641.

[0118] The first assembly portion 641 is provided as a concave cavity, and the first mating portion 713 is provided as a flange. The first mating portion 713 is disposed closer to the heat exchange fan 5 relative to the first assembly portion 641. So that when the first bearing moves away from the heat exchange fan 5, the first mating portion 713 can press the first assembly portion 641 to prevent the bushing 71 from moving away from the heat exchange fan 5 and disengaging from the assembly cavity 64.

[0119] In some embodiments, the assembly cavity 64 may include a second assembly portion 642. The second assembly portion 642 is disposed at an opening of the assembly cavity 64 near the heat exchange fan 5, and the second assembly portion 642 is recessed toward the periphery of the assembly cavity 64.

[0120] In some embodiments, the bushing 71 includes a second mating portion 714. The second mating portion 714 is disposed at the open end 712 of the bushing 71, and the second mating portion 714 protrudes toward the periphery of the bushing 71. The second mating portion 714 abuts against the second assembly portion 642.

[0121] The second assembly portion 642 is configured as a concave cavity, and the second mating portion 714 is configured as a flange. The second mating portion 714 is disposed closer to the heat exchange fan 5 than the second assembly portion 642. When the bushing 71 moves away from the heat exchange fan 5, the second mating portion 714 can press the second assembly portion 642 to prevent the bushing 71 from moving away from the heat exchange fan 5 and disengaging from the assembly cavity 64.

[0122] In some embodiments, the inner stator member is detachably connected to the motor housing, eliminating the need for a snap plate to connect and fix the inner stator member. This can reduce the installation of components within the drive motor, thereby reducing installation precision errors and avoiding noise and vibration generated by the rotation of the heat exchange fan.

[0123] In some embodiments, the inner stator member 63 may include a bracket. The bracket can be configured as an iron core and is disposed inside the annular region enclosed by the outer rotor member 62.

[0124] In some embodiments, the inner stator member 63 may include a coil. The coil can be configured as a copper coil or an aluminum coil. The coil is wound around the bracket, and when the coil is energized, the bracket generates magnetism. When the drive motor 6 is powered on, current flows through the coil wound around the bracket to generate an induced magnetic field, causing the bracket to have magnetism. The induced magnetic field interacts with the magnetic field generated by the outer rotor member 62 configured as a permanent magnet, causing the outer rotor member 62 to rotate relative to the inner stator member 63. The rotation of the outer rotor member 62 then drives the heat exchange fan 5 to rotate synchronously.

[0125] In some embodiments, the inner stator member 63 may include a covering portion 633. The covering portion 633 wraps around the periphery of the bracket and the coil, and the covering portion 633 is integrally formed with the bracket and the coil. When installing the inner stator member 63, the bracket, the coil, and the covering portion 633 are assembled as a whole.

[0126] In some embodiments, the covering portion 633 may include a first connecting portion 634. The first connecting portion 634 is disposed at one end of the covering portion 633 away from the heat exchange fan. A second connecting portion 615 is provided at one end of the motor housing away from the heat exchange fan. The first connecting portion 634 is detachably connected to the second connecting portion 615 to facilitate fixing the inner stator member to the motor housing. The motor housing is fixed to the base, and thus the inner stator member can be fixedly connected to the base.

[0127] In some embodiments, the motor housing 61 may include a limiting rib 612. The limiting rib 612 is disposed at the bottom of the motor housing 61.

[0128] In some embodiments, the base 4 may include a motor cavity 42. The motor cavity 42 is disposed on one side of the heat exchange air duct 41. The driving motor 6 is disposed in the motor cavity 42.

[0129] In some embodiments, the base 4 may include a first limiting member 43. The first limiting member 43 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.

[0130] The first limiting member 43 may be set as a limiting groove. The limiting rib 612 may be inserted into the limiting groove in cooperation. The limiting groove engaging with the limiting rib 612 can prevent the limiting rib 612 from axially moving along the heat exchange fan 5, and can limit the freedom degree of the motor housing 61 in the length direction of the main body 300.

[0131] In some embodiments, the driving motor may include a shock absorber 66. The shock absorber 66 is disposed between the inner stator member and the motor housing. The shock absorber 66 is in interference fit with the inner stator member and the motor housing respectively to press the inner stator member and the motor housing tightly, and reduce the vibration between the inner stator member and the motor housing.

[0132] The shock absorber 66 is disposed on the periphery of the inner stator member, which can reduce the vibration of the inner stator member caused by the rotation of the heat exchange fan, avoid transmitting the vibration of the inner stator member to the motor housing and the base, and improve the user experience.

[0133] In some embodiments, the shock absorber 66 may be set as a rubber member.

[0134] In some embodiments, the base may include fixing columns 46. The fixing columns 46 are disposed on the side wall at the edge of the motor cavity. The fixing columns 46 protrude from the base. The number of the fixing columns 46 may be set to at least two for easy positioning.

[0135] In some embodiments, the motor housing may include fixing holes 616 that cooperate with fixing posts 46. The number of fixing holes 616 corresponds one-to-one with the number of fixing posts 46. The fixing posts 46 are inserted into the fixing holes 616 to position the motor housing and prevent the motor housing from rotating relative to the base.

[0136] In some embodiments, the heat exchange fan 5 may include a first flange 53. The first flange 53 is disposed 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 extends axially along the heat exchange fan 5 towards the drive motor 6.

[0137] In some embodiments, the motor housing 61 may include a second flange 613. The second flange 613 extends towards the heat exchange fan 5 along the length direction of the main body.

[0138] The second flange 613 is disposed inside 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 intersect, preventing dust from falling into the interior of the motor housing 61, and further avoiding the loss of the drive motor 6 caused by the ingress of dust.

[0139] In some embodiments, the heat exchange fan 5 may include a fan body 55. The fan body 55 is located in the heat exchange air duct. The fan body 55 is generally cylindrical, and the first flange 53 is connected to the end of the fan body 55 in the axial direction.

[0140] In some embodiments, a fan shaft 56 is provided at the end of the fan body 55, and the fan shaft 56 passes through the first bearing 7.

[0141] In some embodiments, the heat exchange fan 5 may include anti-collision ribs 57. The anti-collision ribs 57 are provided at one end of the fan body 55 close to the first bearing 7. The anti-collision ribs 57 protrude axially from the fan body 55. There is a gap between the anti-collision ribs 57 and the first bearing 7, so that when the heat exchange fan 5 drops, it can run a certain distance relative to the first bearing 7. After the anti-collision ribs contact the first bearing 7, the first bearing 7 plays a buffering role on the anti-collision ribs and the heat exchange fan 5, preventing damage to the heat exchange fan 5 or the drive motor caused by impact.

[0142] In some embodiments, the fan shaft 56 is arranged to pass 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 rotation of the fan shaft 56 around the same rotation axis.

[0143] In some embodiments, the wall-mounted air conditioner indoor unit may further include a second bearing, which is connected to the second end 58 in the axial direction of the heat exchange fan 5. In the axial direction of the heat exchange fan 5, the second bearing is disposed opposite to the first bearing 7, and the fan shaft 56 passes through the second bearing. The first bearing 7 and the second bearing can define the rotation center of the heat exchange fan 5, avoiding the radial wobbling when the heat exchange fan 5 rotates.
