Description

Technical Field

[0001] The present application relates to the technical field of air energy heat pumps, and in particular to a low-noise air energy heat pump. Background Art

[0002] With the development of air energy heat pump technology, air energy heat pumps are increasingly used in heating, cooling and other fields. However, during the operation of existing air energy heat pumps, due to unreasonable air duct design, it often leads to poor circulation and produces loud noise, which affects the user experience. Therefore, it is necessary to provide a new host silent air duct structure to reduce operating noise and improve user experience. In the prior art, the solution to fan noise is mostly to install an external sound insulation cover, but this method has limited effect and high cost. Therefore, an effective noise reduction solution is urgently needed. Utility Model Content

[0003] The embodiment of the present application provides a low-noise air energy heat pump. When the low-noise air energy heat pump is in operation, the airflow is discharged to the outside through the main unit air duct with little noise.

[0004] The embodiment of the present application provides a low-noise air energy heat pump, including a main unit, a condenser, fan blades and a conical air guide cover;

[0005] A host air duct is arranged inside the host, and the condenser is arranged at one end of the host air duct away from the air outlet of the host air duct and is fixedly connected to the host shell, wherein the outer surface of the condenser and the inner wall of the host shell are both provided with sound insulation materials;

[0006] The fan blades are arranged in the air duct of the host, between the condenser and the air outlet, wherein the fan blades are fixedly connected to the housing of the host through a driving device;

[0007] The conical air deflector is arranged at the air outlet and fixed to the main housing through a grid net, wherein a sound absorbing material is arranged on the surface of the conical air deflector facing the air outlet, and the sound absorbing material is arranged on the grid net.

[0008] In the low-noise air-source heat pump described in the embodiment of the present application, the driving device is a motor.

[0009] In the low-noise air-energy heat pump described in the embodiment of the present application, the motor is fixed to the main housing by sheet metal and screws.
