Abstract
The present invention relates to a refrigerator which comprises a freezing chamber, a refrigerating chamber and a soft freezing chamber, the temperature of the freezing chamber is-18 DEG C, the temperature of the refrigerating chamber is maintained from 0 to 10 DEG C, and the temperature of the soft freezing chamber is maintained from-9 to-5 DEG C or-18 DEG C. Food frozen in the soft freezing chamber can be effectively preserved for 20 days, and can not need to be defrozen, and therefore, the present invention avoids the nutrition drain because of repeating defreezing, and simultaneously saves the consumptive electric energy of microwavetempering.
Description
Technical field
The present invention relates to a kind of refrigerator.
Background technology
Existing refrigerator is made up of refrigerating chamber and refrigerating chamber usually, and the evaporimeter of refrigerating chamber and the evaporimeter of refrigerating chamber are in parallel.The temperature of refrigerating chamber is-18 ℃, and the temperature of refrigerating chamber remains on 0～10 ℃.Find that after tested the refrigeration term of validity of food in the time of 3 ℃ is 5 days, the effective shelf-life in the time of 0 ℃ is 7 days, and the effective shelf-life in the time of-3 ℃ is 10 days, and the shelf-life-7 ℃ the time is 20 days.Show that according to investigation the meat product cooling time is accounted for 72% in 2 weeks with interior, and the fish food pot-life accounts for 82% in 2 weeks with interior to the user.Under current state, the user generally be this type of food preservation in-18 ℃ refrigerating chamber, caused a large amount of wastes of energy, and because freezing excessive, when edible, need thaw, cause the loss of nutritional labeling.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of refrigerator with soft freezing chamber is provided, the food of preserving within it need not to thaw when edible, instant cutting, and laborsaving convenient again during cutting, can also save energy simultaneously, avoid the food nutrient composition loss.
The present invention is achieved in that it comprises refrigerating chamber and refrigerating chamber, comprises a soft freezing chamber again.
The temperature of soft freezing chamber can remain on-9 ℃～-5 ℃; Also can adjust to-25～--any one temperature between 5 ℃.
Soft freezing chamber refrigerating chamber relatively independently exists, and refrigerating chamber is following, and refrigerating chamber is last, and soft freezing chamber is placed in the middle; Also can be that refrigerating chamber, refrigerating chamber and soft freezing chamber are compatible; The evaporimeter of refrigerating chamber and the evaporimeter of soft freezing chamber are in parallel, and the one end links to each other with condenser, compressor by magnetic valve, and the other end is connected with the evaporimeter and the compressor of refrigerating chamber, form refrigerant circuit; The evaporimeter of soft freezing chamber is arranged on the top and the periphery of soft freezing chamber, and the bottom of soft freezing chamber is provided with cold storage box, fills the cold-storage material in the cold storage box; Refrigerating chamber and soft freezing chamber are carried out temperature control respectively.
Adopt the present invention, do not need very long food for the preservation time, place it in carry out in the soft freezing chamber soft freezing, when needs are edible, needn't thaw on the one hand, can directly cut or cook, avoided on the other hand repeating to thaw and the nutrition leak that brings, saved the electric energy that microwave thawing consumed simultaneously; In addition, vegetables and fruit are carried out soft freezing, not only can prolong the freshness date of food, and can make the taste of vegetables and fruit more delicious.In addition, soft when freezing when not needing to carry out, also can the temperature of soft freezing chamber be adjusted to consistently by temperature controller with the temperature of refrigerating chamber, promptly-18 ℃, use as refrigerating chamber.
Description of drawings

Fig. 2 is a refrigeration system principle schematic of the present invention.
The specific embodiment
Referring to accompanying drawing, the present invention is applicable to derect refrigerated refrigerator, and it comprises refrigerating chamber 12, refrigerating chamber 11 and soft freezing chamber 13, and the temperature of refrigerating chamber is-18 ℃, and the temperature of refrigerating chamber remains on 0～10 ℃, and the temperature of soft freezing chamber remains on about-9 ℃～-5 ℃; Refrigerating chamber 12 is following, refrigerating chamber 11 is last, soft freezing chamber 13 is placed in the middle, the evaporimeter 31 of refrigerating chamber is installed in the top in the refrigerating chamber, the evaporimeter 32 of refrigerating chamber is installed in the refrigerator backboard, the evaporimeter 33 of soft freezing chamber is arranged on the top and the periphery of soft freezing chamber, be under the dividing plate between soft freezing chamber 13 and the refrigerating chamber 11, bottom at soft freezing chamber, be that cold storage box 7 is set on the dividing plate between soft freezing chamber and the refrigerating chamber, fill the cold-storage material in the cold storage box 7, the cold-storage material can be salt solution, calcium chloride water etc.; Temperature control equipment is set respectively in refrigerating chamber and soft freezing chamber; The compressor 1 of refrigerator, capillary, magnetic valve 6 etc. are installed in the bottom or cabinet insulation layer of refrigerator.
The evaporimeter 31 of refrigerating chamber is in parallel with the evaporimeter 33 of soft freezing chamber, and the one end links to each other with condenser 2, compressor 1 by magnetic valve 6, and the other end is connected with the evaporimeter 32 and the compressor 1 of refrigerating chamber, forms refrigerant circuit.
The present invention has two refrigerating circuits, controlled by freezing room temperature control device and soft freezing chamber temperature controller.During start just, freeze simultaneously in two loops, and magnetic valve 6 two-way are all opened, and a route compressor 1, condenser 2, device for drying and filtering 4, magnetic valve 6, capillary 51, refrigerator evaporator 31 and freezer evaporator 32 are got back to compressor 1; Another route compressor 1, condenser 2, device for drying and filtering 4, magnetic valve 6, capillary 53, soft freezing chamber evaporimeter 33 and freezer evaporator 32 are got back to compressor 1.
When freezer temperature raises, magnetic valve 6 is opened a refrigerating circuit, close another refrigerating circuit, its refrigerating circuit of opening is for to get back to compressor 1 by compressor 1, condenser 2, device for drying and filtering 4, magnetic valve 6, capillary 51, refrigerator evaporator 31 and freezer evaporator 32.
When the soft freezing chamber temperature raises, magnetic valve 6 is opened a refrigerating circuit, close another refrigerating circuit, its refrigerating circuit of opening is for to get back to compressor 1 by compressor 1, condenser 2, device for drying and filtering 4, magnetic valve 6, capillary 53, soft freezing chamber evaporimeter 33 and freezer evaporator 32.When the soft freezing chamber temperature descended, the cold storage box in the soft freezing chamber is cold-storage simultaneously, when freezer temperature reaches setting, compressor stops refrigeration, then cold storage box discharges refrigerating capacity, makes soft freezing chamber remain on-9 ℃～-5 ℃, guarantees soft freezing stable performance.
The present invention also can pass through temperature controller, the temperature of soft freezing chamber is adjusted to consistent with the temperature of refrigerating chamber, promptly-18 ℃, uses as refrigerating chamber.
