Abstract
The utility model discloses a multi-loop controlled refrigeration loop refrigerator, which comprises a refrigerator body, a control circuit arranged on the refrigerator body, and a compressor, wherein, an exhaust opening of the compressor is orderly connected with a condenser and a molecular sieve through pipelines, and n refrigerating zones (n is not less than 3) are arranged between a molecular sieve outlet and a compressor inlet; each refrigerating zone is composed of a capillary and an evaporator, capillary inlets of the n refrigerating zones are orderly connected by n-1 two-position and three-way valves, and each refrigerating zone outlet is connected with a compressor suction opening in parallel by a pipeline. As the utility model is provided with a plurality of the refrigerating zones which are composed of capillaries and evaporators, the inlet ends of each two adjacent branches are communicated by the two-position and a three-way electromagnetic valve, and thereby, an independent multi-loop refrigerating circulating system can be realized; the temperature of each refrigerating zone of a refrigerator can be accurately controlled manually or automatically, or some refrigerating zone is closed mannually or automatically.
Description
Technical field
The utility model relates to a kind of refrigerator, specifically relates to the controlled refrigerating circuit refrigerator of a kind of many circulations.
Background technology
Common derect refrigerated refrigerator is made up of single refrigeration cycle, this structure is compressor, condenser, capillary, refrigeration, the refrigerating evaporator that connects successively, as seen, refrigeration, refrigerating evaporator are cascaded, can not control respectively refrigeration evaporator and refrigerating evaporator, especially more like this to the refrigerator that a plurality of refrigerations, refrigerating chamber are arranged at present.After the Specifeca tion speeification of refrigerator was determined, the configuration of refrigeration system is also corresponding determined that the surplus of adjusting is little.And the user is because the user demand difference, require the refrigerator refrigeration area can carry out certain adjusting, and the refrigerating chamber of above-mentioned direct cooling refrigerator and refrigerating chamber are owing to be cascaded and can not separately work independently, make and to regulate temperature relatively independently, user's ask for something be can not satisfy, refrigeration or freezer temperature etc. regulated as required voluntarily as the user.Though also have in the market a kind of can be to refrigeration, the refrigerator controlled separately of freeze space, this refrigerator is to adopt two cover refrigeration systems, makes this refrigerator cost height, is equivalent to the cost of two refrigerators.
The utility model content:
The purpose of this utility model is the deficiency that exists at above-mentioned prior art and provides a kind of many circulations controlled refrigerating circuit refrigerator.
For achieving the above object, the utility model can be taked following technical proposals:
The utility model comprises refrigerator body, be arranged on the control circuit on the described refrigerator body, compressor, described exhaust outlet of compressor is connected with condenser, molecular sieve in turn by pipeline, between described molecular sieve outlet and compressor air suction mouth, be provided with n refrigeration area, n 〉=3; Each refrigeration area is made up of capillary, evaporimeter; The capillary inlet of a described n refrigeration area is connected successively by n-1 two position three-way valve, and the outlet of each refrigeration area by pipeline and compressor air suction mouth mutually and connect.
Described n=3, the two position three-way valve at the place, capillary inlet of first refrigeration area link to each other with an inlet of described molecular sieve outlet and the two position three-way valve that is arranged on place, the second refrigeration area capillary inlet respectively; Another outlet of two position three-way valve that is arranged on the second refrigeration area capillary place links to each other with the 3rd refrigeration area inlet capillaceous.
For realizing automatic control, described two position three-way valve is the electromagnetic type structure and is electrically connected with the refrigerator temperature controller.
The utility model is owing to be provided with a plurality of refrigeration areas of being made up of capillary, evaporimeter, and the entrance point of described adjacent two branch roads is connected by two-position three way magnetic valve, thereby realize the independently multiple-loop refrigeration circulatory system, can pass through the temperature of manual or accurate automatically each refrigeration area of control refrigerator, or close certain refrigeration area.Its advantage mainly shows one, some user wishes that cryogenic temperature is too low, like this during food consumption or fresh-keeping, perhaps cutting well, thawing time is short again, can control described magnetic valve by temperature controller and reduce the specific freezing refrigeration area working time, to improve the refrigeration area cryogenic temperature; Two, when user's frozen food not for a long time, can only use a specific freezing refrigeration area, reach the using electricity wisely purpose; Three, when the user does not need frozen food, can only use the refrigeration district, close other refrigeration area, play further using electricity wisely purpose; Four, in the winter time, because temperature is lower, the user can close the refrigeration district, only uses other refrigeration area, is beneficial to economize on electricity
Description of drawings:
Fig. 1 is the refrigerating system figure of refrigerator described in the utility model.
The specific embodiment:
As shown in the figure, the utility model comprises refrigerator body, be arranged on the control circuit on the described refrigerator body, compressor 1, described compressor 1 exhaust outlet is connected with condenser 2, molecular sieve 3 in turn by pipeline, be provided with 3 refrigeration areas between described molecular sieve 3 outlets and compressor 1 air entry, the two-position three way magnetic valve 6 of capillary 4 porch of first refrigeration area links to each other with an inlet of described molecular sieve 3 outlets and the two-position three way magnetic valve 6 that is arranged on the second refrigeration area capillary, 4 porch respectively; Two-position three way magnetic valve 6 another outlets that are arranged on the second refrigeration area capillary, 4 places link to each other with the inlet of the 3rd refrigeration area capillary 4; The outlet of 3 refrigeration areas by pipeline and compressor 1 air entry mutually and connect.
