At present, the direct cooling refrigerator on market, usually adopt two kinds of refrigeration systems: 1) refrigeration evaporator and alternating temperature evaporimeter are in parallel, and simultaneously, refrigeration evaporator is connected outlet and is connected with the import of refrigerating evaporator with the alternating temperature evaporimeter; 2) refrigeration evaporator, alternating temperature evaporimeter and refrigerating evaporator are in parallel.
The applicant finds, adopts the first refrigeration system, because the temperature requirement of refrigerating chamber is low, need to reach-18 ℃, realizes that the cryogenic temperature of setting is very difficult.Adopt the second refrigeration system, realize that not only the cryogenic temperature of setting is difficult, the longevity of service of while compressor, Homes Using TV is high.
The built-in wire-tube evaporator of the many employings of the refrigerating chamber of current refrigerator, the technique of this refrigeration and control mode is simple, and technology maturation easily realizes.In the refrigerator work process, evaporation coil surface directly and the air in freezing compartment carry out exchange heat, although can reduce rapidly the temperature in freezing compartment, but because room temperature is poor larger, very easily in the inner bag of refrigerating chamber surface and the surperficial frosting of evaporation coil, frosting position skewness is difficult for defrosting.
Simultaneously, understand according to the applicant, the general built-in evaporator of existing refrigerating chamber refrigeration uses wire-and-tube evaporator, but built-in evaporator not only can occupy the certain space volume, in an indoor or easy frosting, is difficult for defrosting.
Further, the applicant finds, because the hot gas in refrigerating chamber rises, therefore the upper temp of refrigerating chamber is higher, and when therefore using refrigerating evaporator that refrigerating chamber is lowered the temperature, the temperature distributing disproportionation in refrigerating chamber is even, therefore frosting position skewness, be difficult for defrosting.
Summary of the invention
The technical problem to be solved in the present invention is, and is not enough for prior art, and the frosting that proposes a kind of refrigerating chamber is evenly distributed and easy three refrigeration systems that are used for refrigerator of defrosting.
the present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of three refrigeration systems for refrigerator, comprise compressor, the condenser that is connected with the outlet of compressor, the first refrigerating evaporator, refrigeration evaporator, alternating temperature evaporimeter and dynamoelectric switching valve, the outlet of described condenser is connected with the import of dynamoelectric switching valve, the outlet of described dynamoelectric switching valve is respectively by the refrigeration capillary, alternating temperature capillary and freezing capillary and refrigeration evaporator, the alternating temperature evaporimeter be connected the import of refrigerating evaporator and connect, described refrigeration evaporator is connected outlet and is connected with the import of the first refrigerating evaporator with the alternating temperature evaporimeter, also be provided with the second refrigerating evaporator in described refrigerating chamber, the outlet of described the first refrigerating evaporator is connected with the import of the second refrigerating evaporator, the outlet of described the second refrigerating evaporator is connected with the import of compressor, described the first refrigerating evaporator be located between current refrigerator thermal insulation layer and freezing chamber courage and uniform winding on the border sidewall in the freezing chamber courage outside around pipe, described the second refrigerating evaporator is located at freezing chamber the courage inboard and side top relative with refrigerator open.
The present invention adopts the beneficial effect of technique scheme to be: 1) by be provided with the second refrigerating evaporator in refrigerating chamber, with the first refrigerating evaporator be located between current refrigerator thermal insulation layer and freezing chamber courage and uniform winding on the border sidewall in the freezing chamber courage outside around pipe, the second refrigerating evaporator is located at freezing chamber courage inboard and the side top relative with refrigerator open, make the cooling of refrigerating chamber more even, realized that the frosting of refrigerating chamber is evenly distributed and easily defrosting; 2) due to the first refrigerating evaporator be located between current refrigerator thermal insulation layer and freezing chamber courage and uniform winding on the border sidewall in the freezing chamber courage outside around pipe, therefore the first refrigerating evaporator does not take the refrigerating chamber space, has saved the space.
Improvement of the technical scheme is: be connected with dew eliminating tube and device for drying and filtering between described condenser and dynamoelectric switching valve in turn.
Improvement of the technical scheme is: described the second refrigerating evaporator is wire-tube evaporator.
Improvement of the technical scheme is: described the second refrigerating evaporator is plate pipe evaporator.
Improvement of the technical scheme is: described refrigeration evaporator is located on the sidewall of the refrigeration chamber courage outside.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram of three refrigeration systems that are used for refrigerator of the embodiment of the present invention.
Fig. 2 is the structural representation of the first refrigerating evaporator of Fig. 1.
Fig. 3 is the structural representation of the second refrigerating evaporator of Fig. 1.
The specific embodiment
Embodiment
Three refrigeration systems that are used for refrigerator of the present embodiment, as shown in Figure 1, comprise compressor, the condenser that is connected with the outlet of compressor, the first refrigerating evaporator, be used for the refrigerating chamber cooling refrigeration evaporator, be used for alternating temperature evaporimeter and the dynamoelectric switching valve of temperature-changing chamber cooling.Compressor is located in the compressor bin of rear side lower part of refrigerator body.Refrigeration evaporator generally is located on the sidewall of the refrigeration chamber courage outside.Certainly, also refrigeration evaporator can be located on refrigeration chamber courage inside side walls.The alternating temperature evaporimeter generally is located on the sidewall of the alternating temperature chamber courage outside.Certainly, also the alternating temperature evaporimeter can be located on alternating temperature chamber courage inside side walls.
The outlet of condenser is connected with the import of dynamoelectric switching valve, and the outlet of dynamoelectric switching valve is respectively by refrigeration capillary 1, alternating temperature capillary 2 be connected capillary 3 and refrigeration evaporator, alternating temperature evaporimeter and the import of refrigerating evaporator of being connected and be connected.Refrigeration evaporator is connected outlet and is connected with the import of the first refrigerating evaporator with the alternating temperature evaporimeter.
