Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment, and particularly to an air conditioner. Background Art

[0002] An air conditioner, i.e., an air regulator, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in a building or structure. To meet the needs in real life, some air conditioners have a fresh air function, which can transmit outdoor air into the room.

[0003] In the prior art, an air conditioner includes a housing, and an indoor heat exchanger, an indoor fan, and a motor are arranged inside the housing. The motor drives the indoor fan to rotate so that the air flow after heat exchange through the indoor heat exchanger is input into the room, thereby realizing the adjustment of the indoor temperature.

[0004] However, in the prior art, the motor needs to be arranged at one end of the indoor fan, and the motor is connected to the indoor fan through its own output shaft. Therefore, a certain gap needs to be left between the indoor fan and the motor. In addition, some motors use external rotor motors, and the rotor is sleeved on the stator. In an external rotor motor, due to the way it winds the magnetic induction lines, in order to ensure the torque of the motor, the axial length of the rotor will increase. In summary, the motors in the prior art are usually large in size. Therefore, the overall volume of the air conditioner is also large, which affects the user experience. Summary of the Utility Model

[0005] The present utility model solves at least one of the technical problems in the related art to a certain extent.

[0006] To this end, the present application aims to provide an air conditioner, which is safe, simple, and fast in the installation process. The axial magnetic ventilation machine tangential magnetic focusing rotor and the air conditioner fan are integrally injection-molded, eliminating the complex positioning structure for installing the air conditioner fan, and reducing the processing cost of the air conditioner. And in this design, since the rotor is arranged at one axial end of the stator, the axial length of the stator can be set shorter, and the volume of the air conditioner can be reduced.

[0007] To achieve the above object, the present utility model provides an air conditioner, including:

[0008] A housing, on which an indoor air outlet is provided;

[0009] An indoor heat exchanger, which is arranged inside the housing;

[0010] An indoor fan, which is arranged inside the housing;

[0011] An installation shell, which is arranged inside the housing and located at one end of the indoor fan; the installation shell has a first chamber;

[0012] A second chamber is provided at one end of the indoor fan facing the mounting housing; the second chamber is opposite to and communicates with the first chamber;

[0013] A stator is disposed in the first chamber; the axial direction of the stator is the same as that of the indoor fan; the stator is connected to the mounting housing;

[0014] A rotor is disposed in the second chamber; the rotor is connected to the indoor fan; the rotor is located at one end of the axial direction of the stator.

[0015] In the technical solution, the rotor and the stator are separated and arranged axially. The installation process is safe, simple and fast. The tangential magnetic focusing rotor of the axial magnetic ventilator and the air-conditioning fan are integrally injection-molded, eliminating the complex positioning structure for installing the air-conditioning fan, and reducing the processing cost of the air conditioner. And in this design, since the rotor is disposed at one axial end of the stator, the axial length of the stator can be set shorter, reducing the volume of the air conditioner.

[0016] In some embodiments of the present application, a rotating shaft is coaxially provided at one end of the indoor fan facing the stator, and a shaft hole for inserting the rotating shaft is coaxially provided on the stator.

And during installation, the worker only needs to place the rotor in the accommodating cavity, which is convenient for installation and improves the installation efficiency.

[0020] In some embodiments of the present application, a vibration damping member is provided between the stator and the mounting housing.

[0021] In the technical solution, through the design of the vibration damping member, the vibration generated during the operation of the rotor and the stator is effectively absorbed and isolated, reducing the influence of the vibration on the overall structure of the air conditioner, reducing the noise level, and improving the user comfort.

[0022] In some embodiments of the present application, the mounting housing includes a housing and an end cover; the first chamber penetrates through the housing, and the end cover is used to close one end of the first chamber.

[0023] In the technical solution, the first chamber penetrates through the housing, and one end of it is closed by an end cover, which not only ensures the sealing performance, but also facilitates manual installation and production, and is also convenient for overhauling or replacing the stator.

[0024] In addition, the present application also provides an air conditioner, which includes:

[0031] A rotor disposed within the first chamber; the rotor is connected to the installation shell; the rotor is located at one end of the stator in the axial direction.

[0032] In the technical solution, the rotor and the stator are separated and arranged axially. The installation process is safe, simple, and fast. The axial magnetic ventilation fan tangentially magnet-concentrating rotor and the air conditioner fan are integrally injection-molded, eliminating the complex positioning structure for installing the air conditioner fan, which can reduce the processing cost of the air conditioner. And in this design, because the rotor is disposed at one axial end of the stator, the axial length of the stator can be set shorter, which can reduce the volume of the air conditioner.

[0033] In some embodiments of the present application, a rotating shaft is coaxially disposed on the stator, and a shaft hole for inserting the rotating shaft is coaxially opened on the rotor.

[0034] In the technical solution, by inserting the rotating shaft into the shaft hole, this design improves the concentric stability of the rotation of the indoor fan, simplifies the assembly process, improves the reliability and stability of the connection, and reduces the noise and vibration problems caused by loose connection.

[0035] In some embodiments of the present application, a rotating shaft is coaxially disposed on the rotor, and a shaft hole for inserting the rotating shaft is coaxially opened on the stator.
