Description

Wall mounted air conditioner indoor unit

Technical Field

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

Background Art

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 heat exchange 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 from the heat exchange air inlet, and flow to the indoor room from the heat exchange air outlet after heat exchange in the heat exchanger. The drive motor is connected to the heat exchange fan to drive the heat exchange fan to rotate.

In some wall-mounted air conditioner indoor units, the driving motor is usually set as an inner rotor motor, which includes a stator and a rotor, and the stator of the inner rotor motor is set outside the rotor. When the inner rotor motor is powered on, the rotor rotates inside the inner rotor motor, thereby driving the heat exchange fan to rotate.

The inner rotor motor needs to be fixed by rubber rings installed on both sides of the rotor. Since two rubber rings need to be set, there is a large distance between the two rubber rings. The two rubber rings also need to occupy a larger space in the length direction of the main body, which results in a larger installation space required for the inner rotor motor in the length direction inside the main body, which is not conducive to the miniaturization design of the whole machine and cost optimization.

In view of this, this application is filed.

In this embodiment, the air conditioner includes a wall mounted indoor air conditioner and an outdoor air conditioner.

1 to 13 , the wall-mounted air conditioner indoor unit includes a main body 100 , and the main body 100 includes a casing 1 , an indoor heat exchanger and a heat exchange fan.

The main body 100 has a top and a bottom, and the height direction of the main body 100 is from the top of the main body 100 to the bottom of the main body 100; the main body 100 also has a length direction, and the length direction of the main body 100 is from one side of the main body 100 in the left-right direction to the other side of the main body 100. The main body 100 has a front side and a rear side that are arranged oppositely, and the side of the main body 100 facing the user is the front side of the main body 100, and the side opposite to the front side of the main body 100 is the rear side of the main body 100. The front side of the main body 100 to the rear side of the main body 100 is the front-back direction of the main body 100.

The main body 100 at least includes the main body 100 and a heat exchange chamber 1102 and a fresh air chamber 1101 located in the main body 100 , wherein the heat exchange chamber 1102 and the fresh air chamber 1101 are arranged side by side in the length direction of the main body 100 .

The casing 1 is arranged at the top of the room or the upper space of the room, and the casing 1 includes a heat exchange inlet 15, a heat exchange outlet 16, a fresh air outlet and a fresh air inlet, wherein the heat exchange inlet 15 is connected to the heat exchange cavity 1102, the heat exchange outlet 16 is connected to the heat exchange cavity 1102, and the fresh air inlet and the fresh air outlet are connected to the fresh air cavity 1101.

The housing 1 has a front side and a rear side that are opposite to each other, wherein the side of the housing 1 facing the user is the front side of the housing 1 .

The heat exchange air inlet 11 and the heat exchange air outlet 12 extend along the length direction of the casing 1. When the hanging type air conditioner indoor unit is installed on a wall, the direction of the hanging type air conditioner indoor unit parallel to the wall in the horizontal direction is the length direction of the casing 1, that is, the left and right direction of the casing 1 is the length direction of the casing 1.

The heat exchange air inlet 11 is opened at the top of the casing 1, and the heat exchange air outlet 12 is opened at the front side of the casing 1 and arranged near the bottom of the casing 1. Indoor air enters the casing 1 through the heat exchange air inlet 11 and flows back into the room through the heat exchange air outlet 12.

The fresh air inlet is opened at the side of the casing 1, and the fresh air outlet is opened at the top of the casing 1. In other embodiments, the fresh air inlet can be opened at the top of the casing, and the fresh air outlet can also be opened at the side of the casing 1. The opening positions of the fresh air inlet and the fresh air outlet can be reasonably set according to specific scenarios to meet design and use requirements.

The indoor heat exchanger is disposed in the heat exchange cavity 1102 , and is used to exchange heat with the indoor air entering the heat exchange cavity 1102 .

The heat exchange fan 3 is arranged in the heat exchange chamber 1102, and the heat exchange fan 3 is located below the indoor heat exchanger 1104. The heat exchange fan 3 is arranged as a cross-flow fan. The axial direction of the heat exchange fan 3 is arranged in the same direction as the length direction of the main body 100. The heat exchange fan 3 is used to provide power for the flow of indoor air.

Driven by the heat exchange fan 3, the indoor air enters the heat exchange chamber 1102 through the heat exchange air inlet 15 to exchange heat with the indoor heat exchanger 1104, and the indoor air after heat exchange is discharged from the heat exchange chamber 1102 through the heat exchange air outlet 16 to flow into the room.

The indoor unit of the wall mounted air conditioner is usually installed on a wall surface of the room, etc. The outdoor unit 200 of the air conditioner is usually installed outdoors for heat exchange in the outdoor environment.

The outdoor unit of the air conditioner includes an outdoor casing, an outdoor heat exchanger and an outdoor fan.

An outdoor housing is provided in the outdoor housing, wherein an outdoor fan and an outdoor heat exchanger are arranged in the outdoor housing space.

The outdoor housing is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are connected to the outdoor accommodation space. The outdoor air inlet is used to introduce outdoor air into the outdoor accommodation space, and the outdoor air outlet is used to lead the air in the outdoor accommodation space out of the outdoor accommodation space.

Driven by the outdoor fan, outdoor air enters the outdoor accommodation space from the outdoor air inlet and exchanges heat with the outdoor heat exchanger. The outdoor air after heat exchange flows out of the outdoor accommodation space from the outdoor air outlet.

The air conditioner also includes a compressor and a throttling device, wherein the throttling device is used for throttling. The compressor is arranged in the outdoor accommodation space, and the throttling device is also arranged in the outdoor accommodation space.

The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

The compressor 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 exhausted refrigerant gas flows into the condenser.

The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

Among the indoor heat exchanger 1104 and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1104 is used as a condenser, the air conditioner is used as a heater in the heating mode, and when the indoor heat exchanger 1104 is used as an evaporator, the air conditioner is used as a cooler in the cooling mode.

In addition, the air conditioner is equipped with a controller to control the operation of various components in the air conditioner so that the various components of the air conditioner can operate to achieve various predetermined functions of the air conditioner. Among them, the air conditioner is also equipped with a control device. For example, the control device is specifically configured as a remote controller, which has the function of communicating with the controller using infrared or other communication methods. The remote controller is used for the user to control the air conditioner in various ways and realize the interaction between the user and the air conditioner.

The wall-mounted air conditioner indoor unit further includes a driving motor and a first bearing 1103 . The driving motor is disposed at one end of the axial direction of the heat exchange fan 3 , and the driving motor is used to drive the heat exchange fan 3 to rotate.

The driving motor is configured as an outer rotor motor, and the driving motor comprises an outer rotor component 51 and an inner stator component 52 .

The outer rotor 51 is disposed at one axial end of the heat exchange fan 3, and is connected to the heat exchange fan 3. The rotation axis of the outer rotor 51 is coaxially disposed with the rotation axis of the heat exchange fan 3. When the outer rotor 51 rotates, it can drive the heat exchange fan 3 to rotate synchronously.

The inner stator 52 is disposed inside the outer rotor 51, and the outer rotor 51 can rotate relative to the inner stator 52. The inner stator 52 is provided with a bearing hole 5211, and the bearing hole 5211 is disposed on the rotation axis of the inner stator 52.

The first bearing 1103 is disposed in the bearing hole 5211 , the first bearing 1103 is slidably connected to the stator component, and one end of the heat exchange fan 3 in the axial direction is rotatably connected to the first bearing 1103 .

After the drive motor is powered on, the inner stator 52 generates an induced magnetic field, which interacts with the magnetic field generated by the outer rotor 51 to cause the outer rotor 51 to rotate relative to the inner stator 52 , thereby driving the heat exchange fan 3 to rotate synchronously with the outer rotor 51 .

In this embodiment, the driving motor is set as an outer rotor motor. The existing inner rotor motor needs to be provided with two bearings in the length direction of the main body 100, while the outer rotor motor in this embodiment only needs to be connected with one bearing between the driving motor and the heat exchange fan 3, which saves one bearing compared to the inner rotor motor and reduces the cost. At the same time, the length of the heat exchange fan 3 and the driving motor after being connected is shortened in the length direction of the main body 100, which saves the setting space in the heat exchange cavity, and is conducive to reducing the size of the indoor unit of the wall-mounted air conditioner.

The first bearing 1103 is a sliding bearing, and compared with a rolling bearing, the sliding bearing can increase the load capacity of the first bearing 1103. It can be arranged that the sliding bearing is a rubber sliding bearing.

The outer rotor 51 is arranged in a ring shape to facilitate the rotation of the outer rotor 51. The outer rotor 51 is arranged as a permanent magnet, and the outer rotor 51 is connected to the heat exchange fan 3 by injection molding, which can reduce the distance between the drive motor and the heat exchange fan 3, thereby saving space in the length direction of the main body 100 after the drive motor and the heat exchange fan 3 are connected, which is conducive to reducing the appearance size of the indoor unit of the wall-mounted air conditioner, and achieving a compact and beautiful effect.

The wall mounted air conditioner indoor unit also includes a base, which is arranged in the heat exchange cavity, and a heat exchange air duct is formed between the base and the indoor heat exchanger 1104, and the heat exchange air duct is connected to the heat exchange air outlet.

The first limiting plate 22 , the second limiting plate 23 and the third limiting plate 24 are integrally formed with the base, so as to improve the structural strength of the connection between the first limiting plate 22 , the second limiting plate 23 and the third limiting plate 24 and the base.

A fan cavity 25 is defined between the first limiting plate 22 and the second limiting plate 23, and the heat exchange fan 3 is disposed in the fan cavity 25. A motor cavity 26 is defined between the third limiting plate 24 and the second limiting plate 23, and at least part of the drive motor is disposed in the motor cavity 26. The inner stator member 52 is fixedly connected to the third limiting plate 24 to fix the inner stator member 52 and prevent the inner stator member 52 from rotating when the outer rotor member 51 rotates.

The coil is wound around the metal bracket 521, and the coil can be set as a copper coil or an aluminum coil. When the drive motor is powered on, current flows through the coil wound around the metal bracket 521 to generate an induced magnetic field, making the metal bracket 521 magnetic. The induced magnetic field interacts with the magnetic field generated by the outer rotor part 51 set as a permanent magnet, so that the outer rotor part 51 rotates relative to the inner stator part 52, and the rotation of the outer rotor part 51 drives the heat exchange fan 3 to rotate synchronously.

The insulating bracket 52 is arranged between the coil and the metal bracket 521 . The insulating bracket 52 can be set as a plastic bracket. The insulating bracket 52 is set as an integral injection molding. The insulating bracket 52 can separate the coil and the metal bracket 521 to play a role in insulating the coil and the metal bracket 521 .

The insulating bracket 52 is connected to the third limiting plate 24 to fix the inner stator 52 and prevent the inner stator 52 from rotating when the outer rotor 51 rotates. The insulating bracket 52 is fixedly connected to the third limiting plate 24, and the insulating bracket 52 can also be used to support and fix the metal bracket 521 and the coil, and then support the first bearing 1103 through the metal bracket 521, and support the heat exchange fan 3 through the first bearing 1103.

The bearing hole 5211 is disposed in the middle of the metal bracket 521, and the bearing hole 5211 passes through the middle of the metal bracket 521. The first bearing 1103 matches the bearing hole 5211 and is disposed in the bearing hole 5211 near one end of the heat exchange fan 3, so that the heat exchange fan 3 is connected to the first bearing 1103.

A bearing limiting boss 5221 is provided inside the insulating bracket 52, and the bearing limiting boss 5221 is matched with the bearing hole 5211. The bearing limiting boss 5221 is inserted into the bearing hole 5211 from the end of the bearing hole 5211 away from the heat exchange fan 3. The bearing limiting boss 5221 abuts against the first bearing 1103 in the bearing hole 5211 to limit the first bearing 1103 and prevent the first bearing 1103 from moving in the length direction of the main body 100.

The bearing limiting boss 5221 is interference fit with the first bearing 1103 in the bearing hole 5211, thereby preventing the driving motor from slipping during rotation.

The wall-mounted air conditioner indoor unit also includes a second bearing 6, which is configured as a sliding bearing to improve the load capacity of the second bearing 6. The sliding bearing can be configured to be a rubber sliding bearing. The second bearing 6 is connected to one end of the axial direction of the heat exchange fan 3.
