Technical Field
The invention relates to the field of domestic appliances, in particular to a compressor and an air conditioner.
Background
The electric compressor is the core part of refrigeration equipment, and the electric compressor work can produce vibration noise, and among the correlation technique, the suction hole of electric compressor compression portion directly links to each other with motor portion cavity, and along with the intake air flow noise that produces when the compressor operation easily arouses the cavity natural frequency of generator portion and produces the sympathetic response noise, brings the vehicle air conditioning system noise problem.
Disclosure of Invention
The present invention is directed to solving at least one of the problems of the prior art. Therefore, an object of the present invention is to provide a compressor which has low noise, does not easily excite the natural frequency of the cavity of the generator, does not generate resonance, and has a long service life.
The invention also provides an air conditioner with the compressor.
The compressor according to the present invention includes: the air inlet is arranged on the shell; the compression part is arranged in the shell and is provided with an air suction hole, and the air suction hole is communicated with the air inlet hole; wherein a silencer is also arranged in the shell and is positioned between the air suction hole and the air inlet hole.
According to the compressor, the silencer is arranged between the air suction hole and the air inlet hole, when airflow flows through the silencer, energy of a part of the airflow is consumed, so that noise is reduced, meanwhile, the silencer is arranged between the air suction hole and the air inlet hole, the structure of the inner cavity of the compressor is changed, the natural frequency of the inner cavity of the compressor is further changed, the airflow and the cavity of the compressor cannot resonate, vibration and noise of the compressor are reduced, the service life of parts in the compressor is prolonged, and the reliability of the compressor is improved.
According to an embodiment of the present invention, a suction side cavity communicating with the suction hole and the intake hole, respectively, is provided inside the housing, and the muffler is provided in the suction side cavity.
According to an embodiment of the present invention, the compressor further comprises: the main bearing is arranged in the air suction side cavity and sleeved on a rotating shaft of the compressor, and a through hole communicated with the air suction hole is formed in the main bearing; the motor part is arranged in the air suction side cavity, the motor part and the part, provided with the through hole, of the main bearing are arranged at intervals to form a silencing cavity, and the silencer is arranged in the silencing cavity.
According to an embodiment of the invention, the main bearing comprises: the body part is sleeved on the rotating shaft, the installation part is arranged at the end part, close to the compression part, of the body part and extends towards the inner peripheral wall of the shell, the free end of the installation part abuts against the inner peripheral wall of the shell, the through hole is formed in the installation part, and the installation part and the motor part are spaced to form the silencing cavity.
According to an embodiment of the present invention, the muffler is sleeved on the body portion, and an outer periphery of the muffler abuts against an inner peripheral wall of the housing.
According to one embodiment of the invention, the silencer is constructed as a plate-like structure and is provided with silencing holes.
According to one embodiment of the present invention, the silencer is configured as an annular plate, the silencing holes are plural and are provided on the annular plate at intervals.
According to one embodiment of the invention, the muffling hole is selectively opened and closed.
According to one embodiment of the invention, the muffling hole is a circular hole or a semicircular hole.
An air conditioner according to the present invention will be briefly described below.
The air conditioner is provided with the compressor of the embodiment, and the air conditioner is provided with the compressor of the embodiment, so that the air conditioner is low in noise, the compressor cannot resonate with air flow, and the service life of the compressor is long.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
