Abstract
The utility model relates to an electric refrigerator and belongs to the refrigeration equipment technical field, wherein, a refrigeration circuit comprises a compressor, a condenser, capillary tubes, a cooling chamber evaporator and a freezing chamber evaporator which are connected with each other in turn through pipelines; an outlet of the freezing chamber evaporator is connected with an inlet of the compressor; a three-way valve is arranged on a pipeline connecting an outlet of the condenser and an inlet of a capillary tube through series connection; a capillary tube is connected between the other valve hole of the three-way valve and a pipeline connecting an outlet of the cooling chamber evaporator and an inlet of the freezing chamber evaporator; the three-way valve is an electromagnetic valve. The utility model can work in the mode of general refrigerator and also can work in the closed mode of the cooling chamber.
Description
Technical field
The utility model belongs to technical field of refrigeration equipment, particularly a kind of refrigerator that works in general refrigerator pattern or refrigerating chamber " shut " mode".
Background technology
Common derect refrigerated refrigerator is made up of single refrigeration cycle, and this refrigerating circuit comprises compressor, condenser, capillary, refrigerator evaporator, the freezer evaporator that connects successively by pipeline, and the freezer evaporator outlet links to each other with compressor inlet.Be connected in series in this loop, start each time that compressor all can drive refrigeration evaporator and refrigerating evaporator is worked simultaneously, can not control respectively refrigerating chamber and refrigerating chamber.For the high latitude cold district, winter, temperature was low, and cold storage chamber of refrigerator is in useless state substantially in winter, but for above-mentioned reasons, refrigerating chamber can't be closed.Bring big energy waste thus.Be head it off, the someone designs can be to refrigerating chamber and the independent respectively refrigerator of controlling of refrigerating chamber.Because this kind refrigerator has adopted two cover refrigeration systems respectively refrigerating chamber and refrigerating chamber to be freezed, the refrigerator production cost is higher.
The utility model content
The utility model purpose is to provide a kind of refrigerator that works in general refrigerator pattern or refrigerating chamber " shut " mode".
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of refrigerator, its refrigerating circuit comprises compressor, condenser, capillary, refrigerator evaporator, the freezer evaporator that connects by pipeline successively, the freezer evaporator outlet connects compressor inlet, series connection one triple valve on the pipeline that connects condensator outlet and capillary import, another valve opening of triple valve with is connected that refrigerator evaporator exports and the pipeline of freezer evaporator import between connection one capillary.
Triple valve is a magnetic valve.
The utility model is only by the triple valve of connecting on pipeline between the capillary of current refrigerator refrigeration cycle and the condenser, and between triple valve and refrigeration evaporator and refrigerating evaporator connecting pipeline, be connected a capillary, utilize original refrigeration system to set up two cover refrigeration cycles, by adjusting triple valve, both can make refrigerator be in normal mode of operation, and also can make refrigerator be in the refrigerating chamber " shut " mode".Utilize a cover cooling cycle system can realize two kinds of working mode change.For the refrigerator with big refrigerating chamber, the situation that the refrigerating chamber bottom freezes can not appear in state of temperature that can more any control refrigerating chamber.For the high latitude cold district, after closing, refrigerating chamber can avoid energy waste.Behind closing cold room, can also carry out accurately adjusting control in a big way simultaneously to freezer temperature further to reach the purpose of power and energy saving.

Fig. 2 is the utility model refrigeration cycle schematic diagram.
The specific embodiment
Embodiment, a kind of refrigerator, its refrigerating circuit comprises compressor 1, condenser 5, capillary 4, refrigerator evaporator 3, the freezer evaporator 2 that connects by pipeline successively, freezer evaporator 2 outlets connect compressor 1 import, series connection one three-way magnetic valve 6 on the pipeline that connects condenser 5 outlets and capillary 4 imports, three-way magnetic valve 6 another valve openings be connected that refrigerator evaporator 3 exports and the pipeline of freezer evaporator 2 imports between connection one capillary 7.
Claims (2)
1, a kind of refrigerator, its refrigerating circuit comprises compressor, condenser, capillary, refrigerator evaporator, the freezer evaporator that connects by pipeline successively, the freezer evaporator outlet connects compressor inlet, it is characterized in that, series connection one triple valve on the pipeline that connects condensator outlet and capillary import, another valve opening of triple valve with is connected that refrigerator evaporator exports and the pipeline of freezer evaporator import between connection one capillary.
2, refrigerator as claimed in claim 1 is characterized in that, triple valve is a magnetic valve.
