Description

Noise reduction structure rack with enlarged exhaust containing cavity

Technical Field

The utility model relates to a compressor technical field specifically is an exhaust appearance chamber adds big structure frame of making an uproar that falls.

Background

Inside the compressor, an S-pipe is usually provided for suction and a frame, the inlet section of the S-pipe communicating with a chamber in the frame. The traditional frame sealing chamber is generally provided with a cover plate at the top by adopting bolt threads so as to achieve the sealing effect. However, with this type of seal, a raised threaded connection is required within the chamber for connection to the screw. As shown in fig. 1, 6 in fig. 1 is a sealing chamber on an existing rack, 5 is a threaded connection portion for connecting a cover plate of the sealing chamber in the prior art, and due to the existence of 5, a space in the sealing chamber becomes smaller, so that the noise generated during the operation of the compressor is relatively high, the operating environment of the compressor is affected, and the noise generated during the operation of the refrigerator is relatively high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a to prior art not enough, the utility model provides a structure frame of making an uproar falls in exhaust appearance chamber increase can reduce the noise of compressor during operation after the use.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a noise reduction structure frame that exhaust appearance chamber enlarges, includes frame body and sets up the exhaust appearance chamber on the frame body, the open-top department in exhaust appearance chamber is provided with sealed lid, and shown sealed lid adopts the mode of metal punching press sealed fixed with the exhaust appearance chamber between.

Preferably, a sealing gasket is arranged between the sealing cover and the exhaust cavity, and the sealing gasket is a steel gasket.

Preferably, the top of the sealing cover is arc-shaped, and a flange part is arranged inside the exhaust cavity.

The utility model provides a structure frame of making an uproar falls that exhaust appearance chamber increases possesses following beneficial effect: this exhaust holds the structure frame of making an uproar that falls that the chamber increases, compare in traditional frame mechanism, remove the bolted connection part in the exhaust holds the intracavity, increased the space in exhaust holds the intracavity, because of the exhaust holds the chamber and is the closed condition, makes it become the resonant cavity to the purpose of making an uproar falls in the time of having reached the air admission and exhausting, reduces the noise of compressor during operation, has optimized the operational environment of compressor.

In the figure: the air compressor comprises a frame body 1, an exhaust accommodating cavity 2, a sealing cover 3, a sealing washer 4, a threaded connecting part 5, a sealing cavity structure of a traditional frame 6, a sealing cover mechanism on a traditional frame 7, a threaded connecting column on a traditional frame 8, a compressor shell 9, a 10S pipe, a silencer 11, a compressor driving mechanism 12, a pressure pumping mechanism 13 and an air outlet cavity 14.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Please refer to fig. 6, which is a schematic view of an assembly structure of the compressor. In the figure: 9 is the casing of compressor, the inside of frame body 1 installation and compressor casing 9 to muffler 11 sets up in one side of frame body 1, and during operation, drives through compressor actuating mechanism 12 and takes out pressure mechanism 13 with gas suction muffler 11, and gas enters into the exhaust after muffler 11 through the pipeline and holds 2 insides in the chamber and carry out the amortization and fall the noise after the improvement. In the conventional art, both exhaust plenum chambers 2 are used for intake air while simultaneously drawing in air. After improvement, the exhaust cavity 2 is a closed cavity, when the exhaust cavity 2 passes through, the volume of the exhaust cavity 2 is increased, so that the noise reduction effect can be effectively achieved, and then gas enters the inside of the gas outlet cavity 14 through a pipeline and finally enters the inside of the S pipe.

The utility model provides a technical scheme: a noise reduction structure rack with an enlarged exhaust containing cavity comprises a rack body 1 and an exhaust containing cavity 2 arranged on the rack body 1. The traditional exhaust cavities 2 are different from each other, work independently and are used for air suction. In this scheme, adopt one to exhaust and hold 2 chambeies and breathe in, another exhaust holds the mode of chamber amortization, can reduce the noise of compressor during operation under the prerequisite that does not influence compressor performance, has reached the purpose that the amortization was fallen and is made an uproar. The frame body 1 is made of metal material. The top opening of the exhaust containing cavity 2 is provided with a sealing cover 3, and the sealing cover 3 and the exhaust containing cavity 2 are sealed and fixed in a metal stamping mode.

A sealing washer 4 is arranged between the sealing cover 3 and the exhaust containing cavity 2, and the sealing washer 4 is a steel washer. The steel pad replaces the traditional paper pad, and the leakproofness is better to life is also longer. The sealing cover 3 is fixed on the top of the exhaust cavity 2 in a stamping mode.

The top of the sealing cover 3 is formed in an arc shape, and a flange portion is provided inside the exhaust receiving chamber 2.

The utility model discloses having removed the traditional threaded rod fixed part that exhausts and having held the chamber 2, having increased the container that the chamber 2 was held in the exhaust, like this can the effectual reduction compressor noise at the during operation. When the silencer is in work, gas enters one of the exhaust containing cavities 2 with the threaded rod fixing parts removed through the silencer, the gas forms a resonance effect in the exhaust containing cavities 2 to achieve the purpose of noise reduction, then reaches the inside of the gas outlet cavity 14 through a pipeline, and then is output through the S pipe.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
