Description

Technical Field

[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] When the driving motor is set as an outer rotor motor, the outer rotor motor includes an outer rotor component and an inner stator component. The outer rotor component is fixed on the heat exchange fan, and the inner stator component is fixed on the base. A rotation gap is set between the outer rotor component and the inner stator component, and there is no fixed connection between the outer rotor component and the inner stator component.

[0004] During the actual rotation process, the heat exchange fan tends to be pulled axially and move toward the drive motor. For example, when the heat exchange fan adopts a helical tooth fan structure, the noise can be effectively reduced. However, the helical tooth fan structure has tangential pressure, which will cause the fan to be forced to move in the axial direction. The different magnetic attraction forces of the opposite sides of the outer rotor to the inner stator will cause the heat exchange fan to move left and right.

[0005] In view of this, this application is filed. Utility Model Content

DETAILED DESCRIPTION

[0078] 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.

[0079] This embodiment provides a wall mounted air conditioner indoor unit. Figure 1-Figure 15 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 5 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.

The coil is wound around the bracket 631, and the coil is energized to make the bracket 631 magnetic. When the drive motor 6 is energized, current flows through the coil wound around the bracket 631 to generate an induced magnetic field, so that the bracket 631 has magnetism. 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.

[0135] In some embodiments, the inner stator 63 may include a covering portion, which wraps around the bracket 631 and the outer periphery of the coil, and the covering portion is integrally formed with the bracket 631 and the coil. When installing the inner stator 63, the bracket 631, the coil and the covering portion are assembled as a whole.

[0136] In some embodiments, the drive motor may include a shock absorber 66, which is disposed between the inner stator component and the motor housing. The shock absorber 66 is interference fit with the inner stator component and the motor housing, respectively, to press the inner stator component and the motor housing together to reduce vibration between the inner stator component and the motor housing.

[0137] The shock absorbing member 66 is arranged 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.

[0138] In some embodiments, the shock absorbing member 66 may be configured as a rubber member.

[0139] 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. The card plate 65 can press the shock absorber 66 to prevent the shock absorber from falling out along the length direction of the main body.

[0140] In some embodiments, the card board may include a first connection portion 634, which is arranged at the edge of the card board. A second connection portion 615 is provided at the end of the motor housing away from the heat exchange fan 5. The first connection portion 634 and the second connection portion 615 are detachably connected to fix the inner stator component to the motor housing. The motor housing is fixed on the base, and the inner stator component can be fixedly connected to the base.

[0141] In some embodiments, the second connection portion 615 can be configured as a latch hole, and the first connection portion 634 can be latched into the latch hole.

[0142] See also Figure 16-Figure 17 In some embodiments, the heat exchange fan 5 is subjected to an axial force moving toward the drive motor when rotating.

[0143] In some embodiments, the fan is provided with blades that are tilted relative to the direction of the main body. When the driving motor drives the heat exchange fan 5 to rotate, the air enters the first cavity and the heat exchange air duct through the heat exchange air inlet, and flows out through the heat exchange air outlet under the drive of the heat exchange fan 5. When the air flows through the tilted blades, radial force and axial force that push the heat exchange fan can be generated, so that the fan will be subjected to an axial force moving toward the driving motor. In the length direction of the main body, the different magnetic attraction forces of the opposite sides of the outer rotor part 62 on the inner stator part 63 will cause the heat exchange fan 5 to move left and right.

[0144] In some embodiments, the outer rotor component 62 may include a third magnetic ring portion 93, which is disposed on the periphery of the inner stator component 63. The third magnetic ring portion 93 is magnetized so that the third magnetic ring portion 93 has a magnetic attraction force, which can act on the inner stator component 63.

[0145] In some embodiments, the outer rotor 62 may include a fourth magnetic ring portion 94 , which is connected to the third magnetic ring portion 93 . The fourth magnetic ring portion 94 is located on a side of the third magnetic ring portion 93 close to the heat exchange fan 5 .

[0146] In some embodiments, the outer rotor component 62 may include a fifth magnetic ring portion 95, which is connected to the fourth magnetic ring portion 94, and the fifth magnetic ring portion 95 is located on a side of the fourth magnetic ring portion 94 close to the heat exchange fan 5, and the fifth magnetic ring portion 95 is fixedly connected to the heat exchange fan 5.

[0147] The third magnetic ring portion 93 can generate a third magnetic attraction force on the bracket 631, the fourth magnetic ring portion 94 does not generate a magnetic attraction force on the bracket 631, and the fifth magnetic ring portion 95 can generate a fifth magnetic attraction force on the bracket 631, and the third magnetic attraction force is greater than the fifth magnetic attraction force.

[0148] In some embodiments, the magnetic field strength of the third magnetic ring portion 93 is greater than the magnetic field strength of the fifth magnetic ring portion 95 , and the magnetic field strength of the fifth magnetic ring portion 95 is greater than the magnetic field strength of the fourth magnetic ring portion 94 .

[0149] In some embodiments, the third magnetic ring portion 93 is arranged in a circular ring shape so that the third magnetic attraction force of the third magnetic ring portion 93 is relatively balanced in all directions of the bracket 631, so that the magnetic force exerted on the heat exchange fan 5 when rotating is uniform, avoiding vibration.

[0150] In some embodiments, the fifth magnetic ring portion 95 may be magnetized so that the fifth magnetic ring portion 95 has a weak magnetic force.

[0151] In some embodiments, in the length direction of the main body, the bracket 631 is arranged on a side of the fifth magnetic ring away from the heat exchange fan.

[0152] The bracket 631 can be made of silicon steel sheet, which has good magnetic conductivity.

[0153] The weak magnetic force of the fifth magnetic ring portion 95 can magnetically attract the bracket 631 , thereby facilitating the driving motor to be pulled closer to the side close to the heat exchange fan 5 .

[0154] In some embodiments, the fourth magnetic ring portion 94 is fixedly connected to the heat exchange fan 5 , and the fourth magnetic ring portion 94 and the heat exchange fan 5 are integrally formed by injection molding.

[0155] In some embodiments, the fifth magnetic ring portion 95 is fixedly connected to the heat exchange fan 5 , and the fifth magnetic ring portion 95 and the heat exchange fan 5 are integrally formed by injection molding.

[0156] In some embodiments, the third magnetic ring portion 93 may form a magnetic field, and the third magnetic ring portion 93 is used to provide driving force for the driving motor.

[0157] In some embodiments, the fourth magnetic ring portion 94 is configured to not generate magnetic attraction on the bracket 631. The fourth magnetic ring portion 94 is made of non-magnetic material. The fourth magnetic ring portion 94 can serve to isolate the magnetic field between the third magnetic ring portion 93 and the fourth magnetic ring portion 94, thereby preventing the magnetic field formed by the third magnetic ring portion 93 from interfering with the magnetic field of the fifth magnetic ring portion 95, thereby avoiding the magnetic attraction of the magnetic field of the fifth magnetic ring portion 95 on the circumference of the bracket 631 due to an unbalanced effect, thereby avoiding the problem of vibration and noise generated by the rotation of the heat exchange fan 5.

[0158] The fifth magnetic ring portion 95 generates a fifth magnetic attraction force on the bracket 631 , that is, the bracket 631 generates a reaction pulling force on the fifth magnetic ring portion 95 . The pulling force is in the same direction as the axial force on the heat exchange fan 5 , thereby preventing the heat exchange fan 5 from moving left and right.

[0159] In some embodiments, in the projection of the height direction of the main body, the third magnetic ring portion 93 and the bracket 631 at least partially overlap, so that the third magnetic ring portion 93 can maintain a stable state with the bracket 631 through magnetic attraction.

[0160] In some embodiments, in the projection of the height direction of the main body, the center of the third magnetic ring portion 93 coincides with the center of the bracket 631, and the symmetry center of the third magnetic ring portion 93 coincides with the symmetry center of the bracket 631, so that in the length direction of the main body, the third magnetic ring portions 93 on the left and right sides of the bracket 631 exert equal forces on the bracket 631, so that the third magnetic ring portion 93 can rotate stably corresponding to the center position of the bracket 631, thereby allowing the heat exchange fan 5 to rotate stably.

[0161] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the third magnetic ring portion 93 is m, and m can be any value between 16mm-19mm. m can be 16mm, that is, m≥16mm, which can ensure that the size of the third magnetic ring portion 93 is not too small, and can ensure that the third magnetic ring portion 93 generates sufficient magnetic attraction force on the bracket 631, thereby improving the torque and work efficiency of the drive motor.

[0162] In some embodiments, m can be 19 mm, that is, m≤19 mm, which can prevent the size of the third magnetic ring portion 93 from being too large, thereby avoiding the size of the main body in the length direction being too large to affect the appearance, and avoiding the size of the third magnetic ring portion 93 being too large to effectively utilize the magnetic force of the third magnetic ring portion 93. m≤19 mm can reduce costs.

[0163] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the fourth magnetic ring portion 94 is n, and n can be any value between 2mm-4mm. n can be 2mm, that is, n≥2mm, which can ensure that the size of the fourth magnetic ring portion 94 is not too small, thereby ensuring the magnetic isolation effect of the fourth magnetic ring portion 94 and improving the connection strength of the fourth magnetic ring portion 94 connecting the third magnetic ring portion 93 and the fifth magnetic ring portion 95.

[0164] In some embodiments, n can be 4 mm, that is, n≤4 mm, so that the size of the fourth magnetic ring portion 94 will not be too large, avoiding the size of the main body in the length direction being too large to affect the appearance, and avoiding the size of the fourth magnetic ring portion 94 being too large to cause cost waste. n≤4 mm can reduce costs.

[0165] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the fifth magnetic ring portion 95 is p, and p can be any value between 5mm-7mm. p can be 5mm, that is, p≥5mm, which can prevent the size of the fifth magnetic ring portion 95 from being too small, increase the area of ​​the fifth magnetic ring portion 95 combined with the heat exchange fan 5, and improve the structural strength of the fifth magnetic ring portion 95 after being combined with the heat exchange fan 5.

[0166] In some embodiments, p can be 7mm, that is, p≤7mm, which can prevent the size of the fifth magnetic ring portion 95 from being too large, avoiding the size of the main body in the length direction being too large to affect the appearance, and avoiding the size of the fifth magnetic ring portion 95 being too large to cause cost waste. p≤7mm can reduce costs.

[0167] In some embodiments, in the projection in the height direction of the main body, the single-sided protruding bracket 631 of the third magnetic ring part 93 has a first parameter value, and the first parameter value can be set to 3mm-5mm. The first parameter value can be set to 5mm, that is, the first parameter value is less than or equal to 5mm, so as to prevent the third magnetic ring part 93 from being too large in the length direction of the main body and affecting the appearance, and to avoid the third magnetic ring part 93 being too large and unable to effectively utilize the magnetic force of the third magnetic ring part 93. The first parameter value is less than or equal to 5mm to reduce costs.

[0168] In some embodiments, the fifth magnetic attraction force is set to 1 / 10 of the third magnetic attraction force, which can improve the effect of the fifth magnetic attraction force in balancing the axial force exerted on the heat exchange fan 5 and prevent the heat exchange fan 5 from moving back and forth in the length direction of the main body.

[0169] In some embodiments, the fifth magnetic ring portion 95 is magnetized by a Halbach magnetization method.

[0170] In some embodiments, the third magnetic ring portion 93 is magnetized by a Halbach magnetization method. The Halbach magnetic field waveform is sinusoidal and has no harmonic magnetic field, which can improve noise.

[0172] In some embodiments, the angle between the planes of adjacent permanent magnets is 30°-45°, so that the electromagnetic force curve converges on one side of the inner surface of the outer rotor 62, which can enhance the magnetic field. One side of the outer surface of the outer rotor 62 does not converge the magnetic field, and a magnetic conductive ring is not required.
