Abstract
The utility model discloses a refrigerator refrigeration circulating device, which comprises a compressor, an accumulator, a magnetic valve, a device for drying and filtering and a condenser, wherein the magnetic valve is a bistability magnetic valve, the accumulator is connected with a three-way pipe, two branch lines are connected between the magnetic valve and the three-way pipe, one branch line is connected with a partial freezing evaporator, a second cold storage evaporator, a first cold storage evaporator and a cold storage capillary tube, and the other branch line is connected with a freezing evaporator and a freezing capillary tube. The freezing and the cold storage functions of the utility model are fully independently controlled and are not mutually affected, the micro-freezing chamber is capable of being arranged in a refrigerating chamber, thereby the utility model has an energy-saving effect.
Description
Technical field
The utility model relates to a kind of refrigerator refrigerating cycle apparatus.
Background technology
In the market the refrigerating circulatory device of most refrigerator by a compressor as executing agency, series connection refrigeration, freezing two evaporimeters in kind of refrigeration cycle, refrigerating evaporator guarantees freezer temperature about-18 ℃, and refrigeration evaporator guarantees that temperature of refrigerating chamber is about 5 ℃.Because two evaporimeters are under the same operating mode, can not regulate respectively, can only be from designing the ratio of their refrigerating capacity of coupling rationally, to satisfy refrigeration, the requirement of refrigerating chamber refrigeration.Fig. 1 has provided a kind of improved refrigerator refrigerating cycle apparatus, and it comprises the refrigerating evaporator 14, refrigeration evaporator 11 of compressor 1, series connection, magnetic valve 8, refrigerating chamber temperature controller 13, refrigerating chamber temperature controller 12, capillary 9, evaporimeter 4, dew eliminating tube 3, evaporimeter heating tube 5.In the ordinary course of things, magnetic valve often leaves, refrigerating evaporator 14, the refrigeration evaporator 11 of refrigerant through connecting, and after temperature of refrigerating chamber reaches predetermined value, closed electromagnetic valve, all refrigerants are only by refrigerating evaporator 14.After adopting magnetic valve, can realize the snap frozen mode, promptly close magnetic valve at the very start, all the refrigerating capacity of refrigerants is used for refrigerating chamber, implements snap frozen when making it, and opens magnetic valve again after freezing, allows a small amount of refrigerant enter refrigeration evaporator, refrigerates.Just can realize two temperature controls that could realize with a compressor like this by two compressors.But refrigerating chamber can not be closed separately, can't realize that freezing, refrigeration closes arbitrarily between two Room.In order to solve meat product through-18 ℃ of problems that are difficult to cut after freezing, the refrigerator that has at present is provided with-7 ℃ refrigerating chamber in refrigerating chamber.Because the basic storing mode of most of town users eats for a long time with a large amount of storages by the past, changes storage in a small amount into, the short time is edible.And short time storage food only needs little freezing get final product, therefore-18 ℃ refrigerating chamber and being of little use, and the user uses refrigerating chamber always on the other hand, can the temperature of refrigerating chamber be impacted, and is unfavorable for energy-conservation.
Summary of the invention
The purpose of this utility model is for a kind of freezing, fully independent control of refrigeration being provided, being independent of each other, and refrigerating chamber can be arranged in the refrigerating chamber, has more the refrigerator refrigerating cycle apparatus of energy-saving effect.
Main technical schemes of the present utility model is: this refrigerator refrigerating cycle apparatus comprises compressor, reservoir, magnetic valve, device for drying and filtering, the condenser that connects successively, wherein magnetic valve is a bistable electromagnetic valve, reservoir is connected with three-way pipe, between magnetic valve and three-way pipe, be connected two branch roads, be connected with little evaporimeter, second refrigeration evaporator, first refrigeration evaporator, refrigeration capillary of freezing on the branch road; Be connected with refrigerating evaporator, freezing capillary on another branch road.
The utility model is complete independently by switching respectively the work of refrigerating evaporator and refrigeration evaporator of bistable electromagnetic valve, they are independent of each other, and can realize three kinds of duties: first kind is normal operating conditions, timesharing by magnetic valve is switched, can guarantee that cold compartment of refrigerator, refrigerating chamber, refrigerating chamber reach normal working temperature, and under this kind state,, can realize functions such as quick-frozen when refrigerating chamber, when refrigerating chamber closes; Second kind of state is closing cold room and refrigerating chamber, only keeps the refrigerating evaporator loop, only opens refrigerating chamber.The third state is to close refrigerating chamber, only uses refrigerating chamber, refrigerating chamber.The utility model has not only that aforementioned series connection dual-cycle plant refrigerating capacity is big, all advantages of wide climate zone, original refrigerator evaporator surface temperature can be improved simultaneously, have more energy-saving effect.The utility model is arranged on refrigerating chamber and has not only solved in the refrigerating chamber because refrigeration evaporator is little, and cold-producing medium can not be vaporized in evaporimeter fully, needs to rely on reservoir to vaporize, and power consumption is bigger.Can avoid simultaneously because of use refrigerating chamber often opens refrigerating chamber, thereby reduce power consumption.
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 existing series connection double round robin device for cooling;
Fig. 2 is the structural representation of an embodiment of the utility model.
The specific embodiment
As shown in Figure 2, present embodiment comprises compressor 1, reservoir 16, magnetic valve 8, device for drying and filtering 7, the condenser 3 that connects successively, wherein magnetic valve 8 is bistable electromagnetic valves, one end of reservoir 16 is connected with three-way pipe 15, between magnetic valve 8 and three-way pipe 15, be connected two branch roads, be connected with little evaporimeter 13, second refrigeration evaporator 12, first refrigeration evaporator 11, refrigeration capillary 9 of freezing on the branch road; Be connected with refrigerating evaporator 14, freezing capillary 10 on another branch road.The other end of reservoir 16 is connected with compressor 1 formation through low pressure muffler 17.
