Abstract
The utility model discloses a kind of refrigerator of having electronic expansion valve, comprise a cabinet, and be arranged on the evaporimeter in cabinet, and be arranged on electric expansion valve, compressor, condenser outside cabinet; Described compressor is connected with condenser, and evaporimeter is connected with compressor, and described electric expansion valve is arranged between condenser and evaporimeter and according to the temperature in cabinet and automatically regulates its aperture.
Description
Technical field
The utility model relates to art of refrigeration units, especially a kind of refrigerator of having electronic expansion valve.
Background technology
Refrigerator is generally divided into constant temperature refrigerator and quick-frozen refrigerator; Original constant temperature refrigerator is all opening, stopping by cabinet temperature control compressor; because the frequent starting of compressor can affect life-span of compressor; therefore the cabinet temperature control of original refrigerator all can be set a turn-on temperature; a shutdown temperature; between two temperature, there is a difference; ensure opening and stopping having cycle regular hour of compressor by this difference, thereby also cause in-cabinet temperature fluctuation larger.
And the cold that quick-frozen refrigerator needed at the initial stage of cooling is very large, so the compressor of necessary supporting larger cold, after in-cabinet temperature lowers, only needs very little cold just can maintain cabinet temperature, and on traditional quick-frozen refrigerator, after cabinet temperature drop gets off, compressor stops, when cabinet temperature exceedes the zero point of setting again, compressor starts again, so frequent start-stop, has wasted a lot of electric energy, again the service life of loss compressor.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of constant temperature or quick-frozen refrigerator of the having electronic expansion valve that prevents high frequent startup.
The technical solution adopted in the utility model is:
A refrigerator for having electronic expansion valve, comprises a cabinet, it is characterized in that: it also comprises: be arranged on the evaporimeter in cabinet, and be arranged on electric expansion valve, compressor, condenser outside cabinet; Described compressor is connected with condenser, and evaporimeter is connected with compressor, and described electric expansion valve is arranged between condenser and evaporimeter and according to the temperature in cabinet and automatically regulates its aperture.
Further, described electric expansion valve is made up of controller, valve body and the controlled drive unit, the temperature sensor that are connected with controller, valve body is connected between condenser and evaporimeter, described temperature sensor is for detection of the temperature in cabinet and temperature signal is transferred to controller, and described controller carrys out the aperture of application valve body by controlled drive unit.
Described controller is single-chip microcomputer.
Wherein, described compressor is invariable frequency compressor.
The beneficial effects of the utility model are:
On the utility model constant temperature refrigerator after applying electronic expansion valve, after cabinet temperature drop gets off, only need to detect the temperature in cabinet by temperature sensor, thereby automatically electric expansion valve is reached to the cold output of certain aperture control invariable frequency compressor according to cabinet temperature, just in-cabinet temperature can be maintained constant, and do not need to start continually compressor, extend the service life of compressor;
On the utility model quick-frozen refrigerator, after applying electronic expansion valve, after cabinet temperature drop gets off, only need detecting box temperature, automatically electric expansion valve is reached to certain aperture according to cabinet temperature, just can maintain cabinet temperature, and not need to start continually compressor, extend the service life of compressor.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Fig. 1 is the theory structure block diagram of the utility model constant temperature refrigerator and quick-frozen refrigerator;
Fig. 2 is the structured flowchart of electric expansion valve.
Detailed description of the invention
As shown in Figure 1, a kind of refrigerator of having electronic expansion valve, can be applied in constant temperature refrigerator and quick-frozen refrigerator, comprises a cabinet 10, and is arranged on the evaporimeter 20 in cabinet 10, and is arranged on electric expansion valve 30, compressor 40, condenser 50 outside cabinet 10; Described compressor 40 is connected with condenser 50, and evaporimeter 20 is connected with compressor 40, and described electric expansion valve 30 is arranged between condenser 50 and evaporimeter 20 and according to the temperature in cabinet 10 and automatically regulates its aperture.
Figure 2 shows that electric expansion valve 30, electric expansion valve 30 is made up of controller 301, valve body 302 and the controlled drive unit 303, the temperature sensor 304 that are connected with controller 301, valve body 302 is connected between condenser 50 and evaporimeter 20, described temperature sensor 304 is transferred to controller 301 for detection of the temperature in cabinet 10 and by temperature signal, and described controller 301 carrys out the aperture of application valve body 302 by controlled drive unit 303.
In the time that the utility model is applied in constant temperature refrigerator, its operation principle is, this patent is by temperature sensor 304 detecting box temperature, with the aperture of cabinet temperature control electric expansion valve 30, thereby control the refrigerating capacity output of compressor 40, do not need start-stop compressor 40, in the time that in-cabinet temperature is higher than the temperature requiring, the aperture of electric expansion valve 30 is opened greatly, otherwise in the time that in-cabinet temperature is lower than the temperature requiring, the aperture of electric expansion valve 30 is dwindled, until the aperture of electric expansion valve 30 just meets the load of cupboard, so just can maintain cabinet temperature constant.
In the time that the utility model is applied in quick-frozen refrigerator, its operation principle is, after cabinet temperature drop gets off, only need temperature sensor 304 detecting box temperature, controller 301 is worked according to the controlled drive unit 303 of cabinet temperature control, and controlled drive unit 303 application valve bodies 302 open up into certain aperture, just can maintain cabinet temperature, and do not need to start continually compressor 40, extend the service life of compressor 40.
Wherein, described controller 301 is single-chip microcomputer, and described compressor 40 is invariable frequency compressor, and temperature sensor 304 adopts occasionally thermal resistance of thermoelectricity.
The foregoing is only preferential embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
