Description
Technical field
The utility model relates to a kind of refrigerator, is specifically related to that a kind of to adopt air-cooled and direct-cooled system simultaneously be Three-system Wind, the Direct cold refrigerator of refrigerator refrigeration.
Background technology
Refrigerator is to use very general household electrical appliance, fresh-keeping for satisfying, the needs of the temperature range that refrigeration (temperature range 5～-1 ℃) is different with freezing (temperature range-18 ℃ below) food, refrigerator is provided with chamber between a plurality of refrigerators usually, the chamber is by two sidewalls between refrigerator, rear wall, roof and diapire surround, be provided with in the refrigerator and comprise compressor, the cooling cycle system of evaporimeter and condenser, refrigeration system connects by circulation line, the device that freezes for chamber between refrigerator is an evaporimeter, circulation by cold-producing medium in refrigeration system, particularly in evaporimeter, expand by cold-producing medium, can absorb the heat in its surrounding air, be chamber refrigeration between refrigerator.For realizing the refrigeration of chamber between refrigerator, evaporimeter is arranged on rear wall, sidewall, roof or the diapire of chamber between refrigerator usually.Existing refrigerator refrigeration modes is two kinds, it is a kind of for evaporator of refrigerator is set directly in the wall that surrounds chamber between refrigerator, by its ambient air of evaporator cools, cold is transferred between refrigerator freezes in the chamber, this kind mode is a direct-cooled mode, and direct-cooled mode also can be set directly at evaporimeter between refrigerator in the chamber by the coil pipe mode; Another kind of mode is that evaporimeter is arranged in the wall that surrounds chamber between refrigerator, usually be arranged in the rear wall of chamber between refrigerator, in the wall that surrounds chamber between refrigerator, be provided with the air channel that links to each other with evaporimeter, in the air channel, be provided with Air Blast fan, surround the wall of chamber between refrigerator be provided with refrigerator between the air outlet that is communicated with of chamber, in chamber refrigerator, be that between refrigerator freeze in the chamber with the blow cold air of evaporimeter refrigeration by air outlet by fan.Existing refrigerator, particularly adopting the refrigerator of chamber between a plurality of refrigerators or all adopting direct-cooled mode is the refrigerator refrigeration, or all to adopt air cooling way be refrigerator refrigeration, wherein adopt the refrigerator of direct-cooled mode refrigeration, need evaporimeter be set respectively for chamber between each refrigerator, adopt the refrigerator of air cooling way refrigeration can be respectively that the chamber is provided with evaporimeter between each refrigerator, but one or more evaporimeters are set normally, adopt many with evaporimeter and refrigerator between the air channel that links to each other, chamber, blowing cold wind by Air Blast fan is chamber refrigeration between refrigerator.Freeze with respect to air cooling way, direct-cooled mode is owing to be set directly at the wall that surrounds chamber between refrigerator with evaporimeter or be arranged between refrigerator in the chamber, therefore can save the space of chamber between refrigerator, hold more food, but freeze with respect to air cooling way, direct-cooled refrigeration modes temperature range is regulated narrow, temperature range changes slow, can only be set to fresh-keeping chamber, refrigerating chamber or refrigerating chamber by certain evaporator arrangement as chamber between direct cooling refrigerator, the temperature of chamber is difficult for regulating between refrigerator, when the refrigerator user adjusts the serviceability temperature of chamber between refrigerator because of special requirement, then be difficult for realizing.Because the direct cooling refrigerator variations in temperature is slow, with respect to air-cooled refrigeration modes, the chance of food spoilage increases in the refrigerator simultaneously, and energy consumption of refrigerator is big.
Summary of the invention
The utility model is at the existing refrigerator that is provided with chamber between a plurality of refrigerators, employing direct-cooled mode refrigeration, refrigerator effectively utilizes the space big, employing air cooling way refrigeration, temperature range is regulated wide advantage, a kind of novel Three-system Wind direct cooling refrigerator is provided, in this refrigerator, the direct-cooled mode refrigeration of saving the space is adopted in the chamber between the part refrigerator, it is fast that adjustment is adopted in the chamber between the part refrigerator, and therefore the continuously adjustable air cooling way refrigeration of temperature range can make the user regulate the configuration of refrigerator as required, make full use of the useful space of refrigerator, realize that simultaneously temperature is adjustable continuously, the optimal combination that temperature regulating range is wide.
For achieving the above object, the utility model has adopted following technical proposals.
The utility model discloses a kind of Three-system Wind, Direct cold refrigerator, comprise chamber between three refrigerators, the cooling cycle system that compressor, condenser and the evaporimeter that setting is connected successively by pipeline in the refrigerator forms, the chamber is respectively arranged with evaporimeter between refrigerator, cooling cycle system is controlled by control circuit, it is characterized in that
Between at least one refrigerator the chamber adopt with air channel that evaporimeter is communicated with in fan blows cold wind in the chamber between refrigerator air cooling way be set freeze;
The direct-cooled mode refrigeration that evaporimeter directly freezes is adopted in the chamber between all the other refrigerators.
Usually be provided with refrigeration and freezing function in the refrigerator, for common refrigeration of refrigerator and freezing function are provided, and improve refrigerator simultaneously effectively utilize the space, the air cooling way refrigeration is adopted in the chamber between one of them refrigerator, the direct-cooled mode refrigeration is adopted in the chamber between all the other two refrigerators.
In the utility model, but upper, middle and lower arbitrarily dispose between three chambers of refrigerator, and are preferred:
The refrigerator of described employing air cooling way refrigeration is arranged on the middle part, and the chamber is arranged on the upper and lower part of chamber between wind cooling refrigerator between the refrigerator of employing direct-cooled mode.
Be the demand according to the refrigerator user, realize the random configuration of refrigerator functions, the temperature of chamber is controlled by control circuit between at least one refrigerator, and is adjustable continuously from refrigerated storage temperature to cryogenic temperature.Chamber between the continuously adjustable refrigerator of temperature provides the refrigerator user bigger use flexibility, and it is more free, convenient that refrigerator uses.
For realizing the kind of refrigeration cycle of three chambers of refrigerator, the evaporimeter of three chambers of refrigerator can dispose as required, and is preferred: parallel with one another between the evaporimeter of chamber between described three refrigerators.Parallel with one another between evaporimeter, by the control of stop valve, one or more in the conducting evaporimeter arbitrarily, controlling different evaporimeters respectively is chamber refrigeration between corresponding refrigerator.
Simultaneously refrigeration system can be preferred: between described two refrigerators the chamber evaporimeter with after one section connecting line is in parallel with another evaporator series.After two evaporimeter parallel connections with another evaporator series, make cold-producing medium further return compressor compresses through the evaporimeter of series connection with it through evaporimeter in parallel, therefore can save the energy of refrigeration system, and on two evaporimeters in parallel in parallel pipeline, when not needing between the refrigerator corresponding the chamber refrigeration for it with the evaporimeter of pipeline parallel connection, then it is closed by stop valve, and by the independent conducting cascade evaporation of parallel pipeline device, therefore can realize that an evaporimeter can cut out, not influence the refrigerating function of residue cooling cycle system.
