Abstract
The utility model relates to the technical field of refrigerators in household electric appliances, in particular to a refrigerator multipath refrigerating system, wherein the multipath refrigerating system can control the simultaneous refrigeration of multiple separation chambers of a refrigerator. The multipath refrigerating system of the utility model comprises a refrigeration evaporator, a temperature-change evaporator, a freezing evaporator and a plurality of capillary tubes, wherein a first capillary tube (31) and the refrigeration evaporator (4) are connected in series to form a refrigerant first channel, a second capillary tube (32) and the temperature-change evaporator (5) are connected in series to form a refrigerant second channel, a third capillary tube (33) is a refrigerant third channel, and three channels and a freezing evaporator (7) form a channel after being connected in parallel.
Description
Technical field
The utility model relates to the technical field of refrigerator in the household electrical appliance, especially a kind of refrigerator multiplex refrigeration system.
Background technology
Present most multisystem refrigerator uses two two-bit triplet magnetic valve series connection, reach the purpose of multisystem independent cooling, but chamber refrigeration between can only when first energising can not be freezed simultaneously a plurality of chambers, multisystem does not play due effect, and client's complaint is also more.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly can control the multiplex system cooling system that freezes simultaneously in a plurality of chambers of refrigerator.
For solving the problems of the technologies described above, technical scheme of the present utility model is:
A kind of multiplex system cooling system, comprise refrigeration, alternating temperature, freezing three evaporimeters and some capillaries, described first capillary and refrigeration evaporator series connection constitute cold-producing medium first path, second capillary and alternating temperature evaporator series constitute the cold-producing medium alternate path, three capillary is cold-producing medium the 3rd path, constitutes path with refrigerating evaporator after described three path parallel connections.
Be connected with the 2/2-way magnetic valve respectively on described three paths.
The refrigeration evaporator of described first path respectively is connected a check valve with the alternating temperature evaporimeter of refrigerating evaporator and alternate path with the refrigerating evaporator junction.
The multiplex system cooling system also comprises drier, and described drier is connected with three paths of parallel connection.
The utility model with respect to the beneficial effect of prior art is:
The utility model multiplex system cooling system adopts three independently 2/2-way magnetic valves, gives three paths respectively and controls separately, also can control multichannel and move simultaneously, can be freezed simultaneously in a plurality of chambers of refrigerator.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model multiplex system cooling system.
The specific embodiment
Referring to Fig. 1, the utility model comprises refrigeration, alternating temperature, freezing three evaporimeters, some capillaries, drier, first capillary 31 and refrigeration evaporator 4 series connection constitute cold-producing medium first path, second capillary 32 and 5 series connection of alternating temperature evaporimeter constitute the cold-producing medium alternate path, three capillary 33 is cold-producing medium the 3rd path, constitute path with refrigerating evaporator 7 after three path parallel connections, drier 1 is connected with three paths of parallel connection, the refrigeration evaporator 4 that is connected with 2/2-way magnetic valve 2, the first paths on three paths respectively respectively is connected a check valve 6 with the alternating temperature evaporimeter 5 of refrigerating evaporator 7 and alternate path with refrigerating evaporator 7 junctions.
As shown in the figure, during the refrigerator refrigeration, after cold-producing medium flows through drier 1, be divided into three paths, three paths connect a 2/2-way magnetic valve 2 respectively, control by 2/2-way magnetic valve 2, on the flow direction of cold-producing medium, can walk wherein any one path separately, also can walk wherein any two paths simultaneously, even can move simultaneously by three paths, the refrigerator induction installation in perception refrigerating chamber and temperature-changing chamber temperature simultaneously with the design temperature gap when big, the refrigerator master control borad can be controlled the 2/2-way magnetic valve 2 of refrigeration and alternating temperature path and open simultaneously, and cold-producing medium enters two paths simultaneously, gives refrigerating chamber and temperature-changing chamber refrigeration respectively, even if path of isolated operation refrigeration or alternating temperature, refrigerating chamber also can freeze, and uses unidirectional stop valve 6 to prevent the mutual disturbance of cold-producing medium simultaneously, avoids occurring the not controlled situation of refrigerator room temperature degree.
