Description
Technical field
The present invention relates to a kind of compressor, more particularly, relate to a kind of compressor stopper, it can prevent the collision between compression assembly and the seal container, and described compression assembly is arranged in the seal container, is used for by producing the driving force pressurized gas.
Background technique
In the modern society, be used to make the food of storage to be in the refrigerator of fresh state more and make indoor maintenance more the air conditioner of comfort conditions become necessity.In refrigerator and air conditioner, utilized the cooling cycle system that comprises compressor, condenser, capillary tube and vaporizer.
The compressor that constitutes cooling cycle system changes into kinetic energy with electric energy, and by the kinetic energy compressed refrigerant.Compressor is the core component that constitutes cooling cycle system.
According to the compressing mechanism of compressed refrigerant, compressor can be divided into rotary compressor, scroll compressor, reciprocal compressor etc.
Described compressor mainly comprises: seal container; Drive motor, it is arranged in the seal container, is used to produce driving force; And compression unit, the compressed refrigerant by the driving force that receives drive motor.
In rotary compressor, when drive motor produced rotating force, the rotor of formation compression unit received rotating force and therefore rotates in compression volume, thereby utilized running suction, compression and the refrigerant emission of blade.
In scroll compressor, when drive motor produces rotating force, constitute compression unit the moving volute receive rotating force, and therefore by carrying out the moving motion with fixing volute engagement, thus suction, compression and refrigerant emission.
In reciprocal compressor, when drive motor produced driving force, the piston that constitutes compression unit received described driving force and therefore straight line motion in cylinder space, thus suction, compression and refrigerant emission.In reciprocal compressor, have drive motor to produce the method for rotating force, and this driving force passes to piston by bent axle, and drive motor produces the linear back and forth method of driving force, and should reciprocal driving force be sent on the piston.
According to described compressor, in the process of suction, compression and refrigerant emission, the drive motor and the compression unit that are arranged in the seal container produce vibration and noise.When this vibration and noise transmission when the seal container, the vibration and the noise that leak into the outside add, and make the reliability reduction.Therefore, implemented many restrictions, in this research, adopted the spring technology mostly by being arranged on vibration that drive motor and compression unit produced in the seal container and noise transmission to the research of seal container.
The spring technology is being applied in the situation of compressor, drive motor and compression unit produce transient oscillation, and when compressor is installed in refrigerator or air conditioner or when the refrigerator that compressor is installed or air conditioner move, drive motor and compression unit and seal container bump, thereby cause parts damages and produce collision noise.
In the situation of refrigerator or air conditioner, be installed in refrigerator or air conditioner compressor be dimensioned to minimum so that the mounting zone of compressor is dropped to minimum.In order to reduce the compressor profile, the size that forms the seal container of profile is dropped to minimum.At this, the drive motor and the compression unit that are arranged in the seal container have the dimensions according to the capacity tool, and like this, the spacing between seal container and drive motor that sets within it and the compression unit just diminishes.Because said circumstances even if drive motor and compression unit produce little vibration, then also can produce collision between seal container and drive motor and the compression unit.
As shown in Figure 1, as prevent seal container and comprise drive motor and the compression assembly of compression unit between produce an embodiment of collision, the compression assembly 20 that comprises drive motor and compression unit is arranged in the seal container 10, and spring 30 is installed between the bottom and seal container 10 lower surfaces of compression assembly 20.Spring 30 is helical springs, and the two ends of spring 30 are connected respectively on the outstanding installation unit 11 of lower surfaces in the seal container 10 and from the outstanding installation unit 21 in compression assembly 20 bottoms.
And, be fixedly connected on the sidepiece of compression assembly 20 in a plurality of bar type stoppers 40 of seal container 10 inner surface bendings.Bar type stoppers 40 is utilized and is solder-connected on the inwall of seal container 10, thereby is arranged on the both sides of compression assembly 20.
According to described structure, when compressor operating or compressor moved, compression assembly 20 vibrated under by spring 30 yielding support states.When compression assembly 20 produced transient oscillation, compression assembly 20 was collided with bar type stoppers 40, thereby prevented that compression assembly 20 and seal container 10 from bumping.
But according to described structure, it is complicated respectively a plurality of bar type stoppers 40 being installed on the precalculated position of seal container 10 the insides, and has increased number of assembling steps.
Summary of the invention
Therefore, an object of the present invention is to provide a kind of stopper of compressor, it can prevent the collision between compression assembly and the seal container, and described compression assembly is arranged in the seal container, is used for by producing the driving force pressurized gas.
Another object of the present invention provides a kind of stopper of compressor, and it can simplified structure and number of assembling steps.
For realizing these purposes and other advantages and according to purpose of the present invention, as the description of comprise and broad sense here, the stopper of compressor of the present invention comprises: seal container, it has predetermined inner space; Compression assembly, it is arranged in the seal container, is used for coming pressurized gas by the driving force of drive motor; And resilient supporting unit, it is installed between seal container and the compression assembly, is used for flexibly supporting compression assembly, and described stopper comprises: moving limiting device, it is arranged on seal container and the compression assembly, is used for limit compression assembly moving in the horizontal and vertical directions.
