Description
Technical field
The utility model relates to a kind of refrigerator, relates in particular to a kind of refrigerator with three circulating refrigerating devices, belongs to household electrical appliance technical field.
Background technology
Retrieval finds that Chinese patent discloses multiple refrigerator with three circulating refrigerating devices.This type of refrigerator has refrigeration, three memory cell spaces of freezing and many temperature (or claiming alternating temperature, soft freezing).During use, the food of general quality guarantee period in 3 days to 2 weeks can leave in the how gentle storage unit.The environment temperature of this memory cell can accurately be set with the fate of depositing according to the kind of institute's store food, generally between-1 ℃～-15 ℃.The food that takes out from many warm areas memory cell need not usually to thaw and just can cut, cook.Compare with the refrigerator that refrigerating chamber and refrigerating chamber are only arranged, the refrigerator with three circulating refrigerating devices both can be saved energy consumption, had avoided food can cause nutrition leak again when thawing, and therefore had obvious superiority.
Understand according to the applicant, the refrigeration of existing three circulating refrigerating device refrigerators, many temperature three evaporimeters freezing and refrigerating chamber have two kinds of connected modes in whole refrigeration system: the one, parallel with one another, the 2nd, refrigeration with connect with freezer evaporator again after how warm the evaporimeter of refrigerating chamber be parallel with one another.The former three evaporimeters are independently of one another, and temperature control is convenient, but has the lower shortcoming of energy utilization rate; The latter's the refrigeration and the cooling fluid of how warm freezer evaporator are back in the compressor through freezer evaporator, theoretically, help making full use of the cooling medium refrigeration, save the energy.But during actual the use, how warm the unlatching of refrigerating chamber and refrigerating chamber be frequent more than refrigerating chamber, the compressor start number of times that causes therefrom is also maximum, refrigerating chamber, how warm freezer evaporator connected with freezer evaporator has obviously increased the load of compressor, the temperature adjusting that both had been unfavorable for refrigerating chamber and Duo Wen refrigerating chamber in fact also fails to reach desirable energy-saving effect.
Summary of the invention
The purpose of this utility model is: at the shortcoming and the problem of above-mentioned prior art existence, actual behaviour in service according to refrigerator, propose the little refrigerator of a kind of energy utilization rate height, compressor operating load, thereby make its design more become reasonable with three circulating refrigerating devices.
In order to reach above purpose, the refrigerator that the utlity model has three circulating refrigerating devices comprises refrigerating chamber, refrigerating chamber, is arranged on the many greenhouses in the refrigerating chamber, and refrigerating plant.Described refrigerating plant comprise compressor, condenser, control valve and respectively with freezing, refrigeration, three evaporimeters that many greenhouses are corresponding, the entrance point of described three evaporimeters connects an end of compressor by capillary and control valve, condenser, one of two ports of export of described refrigerator evaporator and many greenhouses evaporimeter connect the entrance point of freezer evaporator, connect the entrance point of compressor after another port of export with freezer evaporator of two ports of export of described refrigerator evaporator and many greenhouses evaporimeter is in parallel.
Like this, during many greenhouses (or refrigerating chamber) evaporimeter refrigeration, cooling fluid is back in the compressor through freezer evaporator, can make full use of cooling medium, saves the energy; And evaporimeter when refrigeration of opening frequent refrigerating chamber (or many greenhouses), compressor does not have extra duty.This shows that compared with prior art, the utility model is more scientific and reasonable, the demand of more realistic use.
In addition, the utility model has also been done following further architecture advances:
A, described many greenhouses are arranged on the bottom of refrigerating chamber fruit and vegetable box.
The memory space in b, described many greenhouses is made of a drawer and sealing drawer stationary barrier suitable for reading at least.
C, described many greenhouses evaporimeter are attached on the refrigerating chamber inner bag of many warm areas bottom.
Be understood that, many greenhouses are arranged in the refrigerating chamber, simple in structure, compact, rationally distributed, can increase the utilization rate of cabinet space, reduce manufacturing cost; The refrigeration system that is adopted can accurately be set the environment temperature of refrigeration, many gentle freezing three memory cells respectively according to the kind of institute's store food and the length of shelf-life; Many greenhouses evaporimeter is attached on the refrigerating chamber inner bag of many warm areas bottom, attachment process is simple, is convenient to operation, and cooling rate is very fast.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is a refrigeration system principle schematic embodiment illustrated in fig. 1.
Fig. 3 is the refrigeration system principle schematic of another embodiment of the utility model.
The specific embodiment
Embodiment one
The nonrestrictive a kind of embodiment that provides the utility model to relate in the accompanying drawing, the utility model will be further described below in conjunction with embodiment.
By shown in Figure 1, the refrigerator that present embodiment has three circulating refrigerating devices comprises that refrigerating chamber 1 that is arranged on top and the refrigerating chamber Room 4, two that are arranged on the bottom respectively have a door of externally opening.The bottom of the fruit and vegetable box 2 in refrigerating chamber 1 is provided with many greenhouses 3, and these many greenhouses 3 are made of a drawer and sealing drawer stationary barrier suitable for reading.Therefore the refrigerator of present embodiment has the airtight cavity volume of refrigeration, many temperature and freezing three food storage.
As can be seen, the refrigerating plant 5 among Fig. 1 mainly is made up of compressor 51, condenser 53, control valve A55, control valve B58, freezer evaporator 62, refrigerator evaporator 57, many greenhouses evaporimeter 60 etc. from the principle schematic of present embodiment refrigeration system shown in Figure 2.Entrance point at above-mentioned three evaporimeters is connected with freezing capillary 61, refrigeration capillary 56 and Duo Wen capillary 59 separately.The import of condenser 53 and outlet are connected with condensation pipe 52 and device for drying and filtering 54 respectively, the other end of condensation pipe 52 links to each other with compressor 51, the other end of device for drying and filtering 54 is connected with the import of control valve A55, two outlets of control valve A55 are connected with the import of refrigeration capillary 56 and control valve B58 respectively, two outlets of control valve B58 are connected with freezing capillary 61 with how warm capillary 59 respectively, the outlet of many greenhouses evaporimeter 60 is connected by the import of muffler with freezer evaporator 62, the outlet of refrigerator evaporator 57 and freezer evaporator 62 is connected with the import of compressor 51 by muffler separately, forms parallel-connection structure.
