Description

Technical Field

[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] Usually, the outer rotor component and the heat exchange fan are fixedly connected by integral injection molding. When the heat exchange fan and the outer rotor component expand and contract due to heat, the bonding force between the two materials changes, and the high-speed outer rotor component and the heat exchange fan may slide relative to each other.

[0005] After the connection strength is improved by structurally designing the connection between the heat exchange fan and the outer rotor, there is an uneven gap between the outer rotor and the inner stator, and the magnetic attraction of the outer rotor to the inner stator is also uneven, causing vibration and noise when the outer rotor rotates.

[0006] In view of this, this application is filed. Utility Model Content

DETAILED DESCRIPTION

[0077] 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.

[0078] This embodiment provides a wall mounted air conditioner indoor unit. Figure 1-Figure 15 Describe the indoor unit of the wall-mounted air conditioner.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] The main body 300 may include a housing 3 , which is disposed in the 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 the user is the front side of the housing 3 .

[0083] 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.

[0084] 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 . Indoor air may enter the first cavity through the heat exchange air inlet 31 .

[0085] 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.

[0086] The main body 300 may include an indoor heat exchanger 1001 , which is disposed in the first cavity and is used to exchange heat with indoor air entering the first cavity.

[0087] 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 .

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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 .

[0092] 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 .

[0093] 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.

[0094] 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.

[0095] 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 .

[0096] 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.

[0097] 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.

[0098] 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 .

[0099] 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.

[0100] 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.

[0101] See also Figure 4-Figure 15 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.

[0102] In some embodiments, the driving motor 6 may include a motor housing 61 , and the motor housing 61 is fixedly connected to the base 4 .

[0103] 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.

[0104] In some embodiments, the driving motor 6 may include an inner stator component 63 , which is disposed inside the outer rotor component 62 , and the outer rotor component 62 may rotate relative to the inner stator component 63 .

[0105] 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 .

[0106] 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 penetrates the inner stator component 63 along the length direction of the main body.

[0108] In some embodiments, the first bearing 7 may include a sleeve 71 , which cooperates with the assembly cavity 64 to restrict the first bearing 7 within the assembly cavity 64 .

[0109] 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.

[0110] In some embodiments, the first bearing 7 may include a sliding member 72 , and the sliding member 72 is disposed inside the sleeve 71 .

[0111] 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 spacing 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 against the closed end 711. This can prevent the fan shaft 56 and the closed end 711 from contacting each other and affecting the rotation when the heat exchange fan 5 rotates normally, and can also prevent the fan shaft 56 and the closed end 711 from contacting each other and affecting the rotation when the heat exchange fan 5 is dropped and moves along its axial direction, and the fan shaft 56 can abut against the closed end 711, and the closed end 711 can provide a buffering force for the fan shaft 56 to prevent the heat exchange fan 5 from being damaged by collision, and can also prevent the heat exchange fan 5 from hitting the drive motor or the base and causing damage to the drive motor and the base.

[0112] 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.

The second matching portion 714 protrudes toward the periphery of the sleeve 71 , and the second matching portion 714 abuts against the second assembly portion 642 .

[0119] The second assembly portion 642 is configured as a concave cavity, and the second matching portion 714 is configured as a flange. The second matching portion 714 is arranged close to the heat exchange fan 5 relative to the second assembly portion 642, so that when the sleeve 71 moves in a 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 a direction away from the heat exchange fan 5 and disengaging from the assembly cavity 64.

[0120] 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 .

[0121] 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 .

[0122] In some embodiments, the base 4 may include a first limiting member 43 , which is disposed in the motor cavity 42 , and the first limiting member 43 cooperates with the limiting rib 612 to limit the axial movement of the motor housing 61 .

[0123] 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.

[0124] 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 , is disposed around the edge of the heat exchange fan 5 , and extends axially toward the drive motor 6 of the heat exchange fan 5 .

[0125] 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.

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 caused by the entry of dust.

[0127] 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 substantially cylindrical, and the first flange 53 is connected to the axial end of the fan body 55 .

[0129] 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. 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. 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.

[0130] In some embodiments, the fan shaft 56 is disposed 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.

[0131] 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 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.

[0132] In some embodiments, the inner stator component 63 may include a bracket 631 , which may be configured as an iron core, and the bracket 631 is disposed inside the enclosed annular portion of the outer rotor component 62 .

[0133] 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 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] In some embodiments, the shock absorbing member 66 may be configured as a rubber member.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] See also Figure 16-17 In some embodiments, the outer rotor component 62 may include a first magnetic ring portion 91, which is disposed on the periphery of the inner stator component 63. The first magnetic ring portion 91 is magnetized so that the first magnetic ring portion 91 has magnetic force, and the magnetic force can act on the inner stator component 63.

[0142] In some embodiments, the outer rotor component 62 may include a second magnetic ring portion 92, which is connected to the first magnetic ring portion 91, and the second magnetic ring portion 92 is located on a side of the first magnetic ring portion 91 close to the heat exchange fan 5, and the second magnetic ring portion 92 is fixedly connected to the heat exchange fan 5.

[0143] The first magnetic ring portion 91 can generate a first magnetic attraction force on the bracket 631 , while the second magnetic ring portion 92 does not generate a first magnetic attraction force on the bracket 631 .

[0144] In some embodiments, the second magnetic ring portion 92 is not magnetized, so that the second magnetic ring portion 92 has no magnetic force or only weak magnetic force.

[0145] In some embodiments, the first magnetic ring portion 91 is arranged in a circular ring shape so that the first magnetic force of the first magnetic ring portion 91 is uniform, so that the magnetic force received by the heat exchange fan 5 when rotating is uniform, thereby avoiding vibration.

[0146] In some embodiments, in order to improve the connection strength between the heat exchange fan 5 and the outer rotor 62 and avoid the problem of relative sliding between the heat exchange fan 5 and the outer rotor 62 due to changes in the bonding force between the heat exchange fan 5 and the outer rotor 62 caused by thermal expansion and contraction, the portion where the second magnetic ring portion 92 is combined with the heat exchange fan 5 can be set to a concave-convex shape to avoid affecting the connection strength due to the excessive smoothness of the portion where the heat exchange fan 5 and the outer rotor 62 are combined, thereby avoiding relative sliding between the heat exchange fan 5 and the outer rotor 62.

[0147] In some embodiments, the second magnetic ring portion 92 may include a protrusion 921 , which is disposed on a side of the second magnetic ring portion 92 away from the first magnetic ring portion 91 , and the protrusion 921 is connected to the heat exchange fan 5 so that the protrusion 921 is fixed to the heat exchange fan 5 .

[0148] In some embodiments, the protrusion 921 is integrally formed with the heat exchange fan 5 , and the protrusion 921 of the second magnetic ring and the heat exchange fan 5 are injection molded as one body through an injection molding process, so that when the outer rotor component 62 rotates, the heat exchange fan 5 rotates synchronously with the outer rotor component 62 .

[0149] Due to the setting of the protrusion 921, the second magnetic ring part 92 will generate a magnetic attraction force on the bracket 631 when it has magnetic force. The different distances between the protrusion 921 set around the second magnetic ring part 92 and the bracket 631 will cause the magnetic attraction force generated by the second magnetic ring part 92 on the bracket 631 to affect the normal rotation of the heat exchange fan 5, thereby generating noise and vibration.

[0150] In this embodiment, the second magnetic ring portion 92 is set to have no magnetic force, so that the second magnetic ring portion 92 does not generate magnetic attraction to the bracket 631, and the protrusion 921 has no magnetic force. During the rotation of the fan, the protrusion 921 does not generate a magnetic field and does not generate magnetic attraction to the bracket 631, thereby not affecting the rotation of the heat exchange fan 5, and at the same time improves the bonding strength between the heat exchange fan 5 and the outer rotor 62.

[0151] In some embodiments, the magnetic field strength of the first magnetic ring portion 91 is greater than the magnetic field strength of the second magnetic ring portion 92 .

[0152] In some embodiments, the second magnetic ring portion 92 may have a weak magnetic force, and the magnetic attraction force generated by the first magnetic ring portion 91 on the bracket 631 is defined as the first magnetic attraction force, and the magnetic attraction force generated by the second magnetic ring portion 92 on the bracket 631 is defined as the second magnetic attraction force, and the first magnetic attraction force is greater than the second magnetic attraction force.

[0153] The first magnetic attraction force is greater than the second magnetic attraction force, so that the first magnetic force generated by the second magnetic ring part 92 with weak magnetic force is insufficient to affect the rotation of the heat exchange fan 5. The first magnetic attraction force generated by the first magnetic ring part 91 on the bracket 631 can ensure that the outer rotor part 62 rotates around the same axis, avoiding the problem of vibration and noise of the heat exchange fan 5 due to the setting of the protrusion 921.

[0154] In some embodiments, in the projection of the height direction of the main body, the first magnetic ring portion 91 and the bracket 631 at least partially overlap, so that the first magnetic ring portion 91 can maintain a stable state with the bracket 631 through magnetic attraction.

[0155] In some embodiments, in the projection of the height direction of the main body, the center of the first magnetic ring portion 91 coincides with the center of the bracket 631, and the symmetry center of the first magnetic ring portion coincides with the symmetry center of the bracket 631, so that in the length direction of the main body, the first magnetic ring portions 91 on the left and right sides of the bracket 631 exert equal forces on the bracket 631, so that the first magnetic ring portion 91 can rotate stably corresponding to the center position of the bracket 631, thereby allowing the heat exchange fan 5 to rotate stably.

[0156] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the first magnetic ring portion 91 is c, and c can be any value between 16mm-19mm. c can be 16mm, that is, c≥16mm, which can ensure that the value of c is not too small, and can ensure that the first magnetic ring portion 91 generates sufficient magnetic attraction on the bracket 631, thereby improving the work efficiency of the drive motor.

[0157] In some embodiments, c can be 19 mm, that is, c≤19 mm, so that the value of c will not be too large, thereby avoiding the main body being too large in length and affecting the appearance, and avoiding the first magnetic ring part 91 being too large and unable to effectively utilize the magnetic force of the first magnetic ring part 91, thereby reducing costs.

[0158] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the second magnetic ring portion 92 is d, and d can be any value between 5 mm and 10 mm. d can be 5 mm, that is, d ≥ 5 mm, which can prevent the size of d from being too small, thereby increasing the area of ​​the second magnetic ring portion 92 combined with the heat exchange fan 5, and improving the structural strength of the second magnetic ring portion 92 after being combined with the heat exchange fan 5.

[0159] In some embodiments, d can be 10 mm, that is, d≤10 mm, so that the size of the second magnetic ring portion 92 in the length direction of the main body is not too large, avoiding the main body being too large in the length direction and affecting the appearance. On the other hand, d≤10 mm can reduce costs.

[0160] In some embodiments, in the projection of the height direction of the main body, the distance between the two farthest points of the outer rotor component 62 is j, and j can be any value between 16 mm and 25 mm. j can be 16 mm, that is, j ≥ 16 mm, which can prevent the size of the outer rotor component 62 in the length direction of the main body from being too small, thereby improving the work efficiency of the drive motor.

[0161] In some embodiments, j can be 25mm, that is, j≤25mm, which can prevent the outer rotor 62 from being too large in the length direction of the main body, thereby avoiding the main body being too large in the length direction and affecting the appearance of the wall-mounted air-conditioning indoor unit. On the other hand, j≤25mm can reasonably reduce costs.

[0162] In some embodiments, the first magnetic ring portion 91 is magnetized by a Halbach magnetization method, and the Halbach magnetic field waveform is sinusoidal and has no harmonic magnetic field, which can improve noise.

[0163] In some embodiments, a plurality of permanent magnets are disposed inside the outer rotor member 62 . The plurality of permanent magnets are disposed around the outer rotor member 62 , and permanent magnets of different magnetic poles are disposed in sequence and spaced apart from each other and around the outer rotor member 62 .

[0164] 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.
