Abstract
The utility model provides a compressor, freezer and refrigerating system, wherein the compressor includes the compressor main part and establishes the compressor main part is outer and be used for controlling the control valve that the compressor main part was admitted air. The utility model discloses can control admitting air of compressor, under the condition that the compressor does not have the admission, the compressor idles, reduces the pressure differential between high-pressure chamber and the low-pressure chamber in the pump body of compressor, has also just reduced the resistance that the compressor starts to shorten the activation time of compressor.
Description
Technical field
The utility model relates to compressor field, more specifically a kind of compressor, refrigerator and its refrigeration system.
Background technique
In refrigerator industry, the requirement of storage diversification, especially to being worth higher food materials, to storage temperature require compared with
Height, so the temperature control requirement stored to it is more accurate, this is for freezing and refrigeration compression mechanism, it is meant that using often
There is the case where short-term frequent starting, this will propose higher requirement to compressor.
As shown in figure 3, label is air entry 11, exhaust outlet 19, crankshaft 17, roller 14, cylinder 15, slide plate 10, electricity respectively
Direction 13, the pump housing resistance torque direction 16 of machine staring torque, after compressor shutdown, there are high-low pressure chamber in pump housing cylinder,
When compressor start, the pressure difference of high-low pressure chamber is reduced rapidly.By the fit clearance of the pump housing pressure difference on both sides is subtracted at present
Small needs take a long time, and effect is bad.
Therefore, this field quickly reduces pressure difference in pump housing method after needing searching to shut down, develops and adapts to frequently open
Dynamic desired compressor is a trend of reach in freezer industry development.
Utility model content
The purpose of the utility model is to provide a kind of compressor, refrigerator and refrigeration system, which can reduce compression
The pressure difference of height chamber in machine makes pump housing moment of resistance when compressor start become smaller, to reach the effect of quick start compressor
Fruit.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of compressor, including compressor main body, the compressor main body are also connected with for controlling the compression owner
The control valve of body air entry switch state.
It preferably, further include dispenser, the gas outlet of the dispenser is connect with the air entry of the compressor main body.
Preferably, the control valve is located between the gas outlet of the dispenser and the air entry of the compressor main body.
Preferably, the control valve is connect with the air inlet of the dispenser.
Preferably, the control valve is solenoid valve.
Preferably, cylinder, crankshaft, roller and slide plate, the roller and slide plate handle are additionally provided with inside the compressor main body
The inside of cylinder is separated into two chambers.
A kind of refrigerator including above-mentioned compressor.
Preferably, the compressor is closed after the control valve has been closed.
Preferably, the compressor interior closing of 3S after the control valve has been closed.
A kind of refrigeration system, including above-mentioned refrigerator.
Compared with prior art, the utility model at least has the advantages that
The utility model compressor can control the switch state of the air entry of compressor, in feelings of the compressor without air inlet
Under condition, compressor idle running, to reduce the pressure difference of high pressure chest and low pressure chamber in compressor pump body, reduce the pump housing to booting
Resistance when starting, so as to shorten the starting time of compressor.
Detailed description of the invention
Fig. 1 is the schematic diagram of an embodiment；
Fig. 2 is the schematic diagram of another embodiment；
Interior view when Fig. 3 is compressor start.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
Shown in referring to Fig.1, a kind of compressor provided for an embodiment, including compressor main body 1 and one are used to control
The control valve 2 of the air entry switch state of compressor main body, as long as control valve 2 is closed, the air entry of compressor main body 1 would not
There is gas sucking, the pump housing of such compressor will be evacuated, so that pumping the pressure balance of intracorporal high-low pressure chamber, work as compression
On startup, the moment of resistance of the pump housing becomes smaller machine, so that it may so that the starting of compressor is more rapid.
In the present embodiment, the main body of compressor is also connect with a dispenser 3, the gas outlet of dispenser 3 and compressor
The air entry of main body 1 connects, and control valve 2 is located between the gas outlet of dispenser and the air entry of compressor main body, is closing in this way
After closing control valve, compressor controls the air inlet of compressor to reach there will be no gas entrance.Control valve is preferred
It is more convenient by control of this solenoid valve to the air inlet of compressor for solenoid valve, rapidly.Gas is additionally provided in compressor main body
The inside of cylinder is separated into two chambers (such as Fig. 3) by cylinder 15, crankshaft 17, roller 14 and slide plate 10, roller 14 and slide plate 10,
After compressor operation, the two are intracavitary to generate draught head, so that low pressure chamber 12 and high pressure chest 18 are formed, the side of its moment of resistance
To be it is contrary with the starting up of compressor, in this way booting when, the starting of compressor will be hindered, when control valve close
After closing air-breathing, compressor idle running will make the draught head balance that two pressures are intracavitary, to reduce what compressor was again started up
Time.
Referring to shown in Fig. 2, in another embodiment, control valve 2 is located at the air inlet of dispenser 3, it can be controlled
The air inlet of dispenser, and the gas in compressor main body comes from dispenser, so controlling dispenser, that is, controls
The air-breathing of the air entry of compressor main body, this scheme can also serve the same role, and can equally make the pump housing of compressor
It vacuumizes, makes air pressure balance in high pressure chest and the low pressure chamber in compressor, to realize quick start compressor.
It includes the refrigerator for having the compressor of control valve that the utility model, which is also protected a kind of,.Control valve has been set in this refrigerator
The switch state of air-breathing for controlling compressor first closes control valve before close compressor, it is ensured that will not be into compressor
Gas vacuumizes the pump housing of compressor, so that the draught head for reaching the high-low pressure chamber in compressor reduces, this also allows for compressing
Pump housing moment of resistance when machine starts becomes smaller, so that compressor effect can quickly be started by reaching.Compressor is closed in control valve
Delay is shut down afterwards, and the time for the shutdown that is delayed is within 3S, so that it may achieve the effect that it is above-mentioned, do not need to allow compressor idle running too
Long, excessive electric energy is wasted.
The utility model also protects a kind of refrigeration system, this refrigeration system includes the refrigerator with control valve compressor,
It can be with quick start compressor.
The utility model is described in detail above by specific embodiment, these detailed description are only limited to
The content of the utility model is helped skilled in the art to understand, the limit to scope of protection of the utility model can not be interpreted as
System.Those skilled in the art should all wrap various retouchings, the equivalent transformation etc. that above scheme carries out under the utility model design
It is contained in the protection scope of the utility model.
