Be understood that, the evaporator designs of this multisystem refrigerator, electrical control designs all more complicated, and relative cost is than higher.
Summary of the invention
In view of above-mentioned deficiency, the object of the present invention is to provide a kind of three-door refrigerator, to simplify the evaporator designs of three-door refrigerator, simplify electrical control simultaneously, reduce its manufacturing cost.
The utility model provides a kind of three-door refrigerator, comprise the compressor, condenser, the evaporimeter that connect successively, evaporimeter comprises first, second portion, third part and the 4th part that links to each other successively at least, evaporimeter first is arranged in the refrigerating chamber, the evaporimeter second portion is arranged in the refrigerating chamber, the evaporimeter third part is arranged in the soft freezing chamber, and evaporimeter the 4th part is arranged in the refrigerating chamber, and evaporimeter the 4th part links to each other with the compressor input.
Optionally, also be provided with evaporimeter the 5th part in the described soft freezing chamber, be connected between evaporimeter first and the second portion.
Preferable, also comprise the temperature monitoring system of controlling the compressor operating time, be arranged in the refrigerating chamber.
Wherein, also comprise device for drying and filtering, be arranged between condenser and the evaporator pipeline.Also comprise defrosting pipe, be arranged between compressor and the condenser pipe
As seen from the above, three-door refrigerator of the present utility model, each chamber has adaptive with it evaporimeter, by optimize cold-producing medium flow through each chamber evaporimeter order, cooperate and adjust disengagement area, thereby only needing to have realized a temperature conditioning unit, just can satisfy refrigerating chamber, refrigerating chamber, soft freezing compartment temperature requirement, simplify the electrical control of three-door refrigerator greatly, reduce the manufacturing cost of refrigerator.
Be that three-door refrigerator of the present utility model is by optimizing the design of evaporimeter, only use a temperature monitoring system just can realize temperature controlling, removed a plurality of temperature monitoring systems and correspondent control circuits from, do not need triple valve, simplify circuit, reduced the cost of manufacture of refrigerator.
And, evaporimeter in the refrigerating chamber is divided into designing two portions, can effectively reduce the temperature of refrigerating chamber, help the fast cooling of temperature of refrigerating chamber again, the device for monitoring temperature of having avoided traditional design to cause detects the higher problem that causes opening for a long time compressor of temperature of refrigerating chamber for a long time.
Description of drawings
Fig. 1 is the evaporation structure schematic diagram of three-door refrigerator of the present utility model.
Fig. 2 is another example structure schematic diagram of evaporimeter of three-door refrigerator of the present utility model.
The specific embodiment
The present invention has optimized the flow through order of cold-producing medium on each evaporimeter, cooperates and adjusts the disengagement area of flowing through, and by a temperature monitoring system temperature of refrigerating chamber, refrigerating chamber, soft freezing chamber is controlled, and reaches the normal refrigerating function of refrigerator.Be elaborated referring to the three-door refrigerator evaporation structure schematic diagram of the present utility model shown in Fig. 1:
Three-door refrigerator comprises refrigerating chamber, refrigerating chamber, soft freezing chamber, evaporimeter comprises at least four parts among Fig. 1, first 5, second portion 8, third part 7, the 4th part 6, series connection successively, and with device for drying and filtering 1, condenser 2, defrosting pipe 3, compressor 4 by the capillary formation loop that links to each other.Because device for drying and filtering 1, defrosting pipe 3 are related with the utility model not quite, this paper no longer gives unnecessary details these two parts.Cold-producing medium in the described loop circulates with the order of compressor, condenser, evaporimeter.
Wherein, evaporimeter first 5 is arranged in the cold compartment of refrigerator, the second portion 8 that links to each other with first 5 is arranged in the refrigerating chamber, the third part 7 that links to each other with second portion 8 is arranged in the soft freezing chamber, the 4th part 6 that links to each other with third part 7 is arranged in the refrigerating chamber, and the 4th part 6 links to each other with the compressor input.
Under the essentially identical situation of each chamber volume, the gross area of described evaporimeter first 5 and the 4th part 6 is less than third part 7, and the area of evaporimeter third part 7 is less than second portion 8.Especially, when the temperature that will make refrigerating chamber, soft freezing chamber and refrigerating chamber maintain 0～5 ℃, subzero 3 ℃ respectively, during subzero 18 ℃ of left and right sides, the area ratio of the gross area of described evaporimeter first 5 and the 4th part 6, third part 7, second portion 8 can be set to 1: 1～1.5: 2.5.Certainly, according to the difference of the thermic load of each chamber of reality, can change what of each chamber evaporator area.
Because it is the most sufficient to flow through the cold-producing medium that comes from condenser 2, and the refrigerant temperature of outflow evaporator to compressor 4 is the highest.Therefore, the refrigeration system pipeline order is designed to: cold-producing medium is introduced into refrigerating chamber (evaporimeter first 5), enter refrigerating chamber (evaporimeter second portion 8) after the outflow again, enter soft freezing chamber (evaporimeter third part 7) then, enter refrigerating chamber (evaporimeter the 4th part 6) at last again, after refrigerating chamber flows out, enter compressor.Such design can guarantee that refrigerating chamber, soft freezing chamber, refrigerating chamber satisfy design temperature simultaneously under different environment temperatures.
Temperature monitoring system is arranged in the refrigerating chamber.Evaporimeter is divided into two parts in refrigerating chamber: first 5 and the 4th part 6; such design can make the temperature of a temperature monitoring system perception refrigerating chamber; by control compressor start, downtime, just can realize the temperature of chamber between three is controlled and the design temperature of chamber between satisfied three simultaneously.Refrigerator evaporator is divided into the temperature that designing two portions both can effectively reduce refrigerating chamber, the fast cooling that helps temperature of refrigerating chamber again, the device for monitoring temperature of avoiding traditional design to cause detect the higher problem that causes opening for a long time compressor of temperature of refrigerating chamber for a long time.And can open compressor for a long time, and unfavorable to the power consumption of refrigerator, also unfavorable service life to compressor.
Be understood that,, also can as shown in Figure 2 one section evaporimeter be set in soft freezing chamber, be called evaporimeter the 5th part 9 herein, be connected between evaporimeter first 5 and the second portion 8 in order to realize the fast cooling of soft freezing chamber.Under the essentially identical situation of each chamber volume, the evaporimeter first and the tetrameric gross area are less than the gross area of third part and the 5th part, and the gross area of third part and the 5th part is less than second portion.Certainly, according to the difference of each chamber volume size of reality, can change what of each room evaporator area.
The above only is preferred embodiment of the present invention; not in order to restriction the present invention; within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement, refrigerator volume and between the increase, minimizing etc. of chamber, all should be included within protection scope of the present invention.
