Description
Technical field
The present invention relates to a kind of energy-saving refrigerator, belong to refrigerator refrigeration wind path circulating technology field.
Background technology
Refrigerator divides direct-cooling type and air-cooled two kinds, the refrigerator that wind cooling refrigerator adopts the cold air forced cyclic type to freeze.The wind cooling refrigerator set inside evaporimeter, evaporimeter is used fin tube type always, be placed in the interlayer between refrigerating chamber and the refrigerating chamber or case in the upper back; Utilize a small-sized fans to force the case inner air convection, through fan and air channel cold air is delivered to each position of refrigerator, to reach cooling purpose; Because evaporimeter discord food directly contacts; Can recover refrigeration after the defrosting, so we can't see the frost that it produces through heating system to the evaporimeter short-term warming at once.
And direct-cooled the rime ice case arranged, and be that food is placed directly in the evaporator surface refrigeration, in a plurality of positions of refrigerator a plurality of evaporimeters are set usually.Because its evaporimeter promptly is the inwall of refrigerator, and defrost system can't be set, so want artificial defrosting.
But the refrigerator refrigeration adopts enclosed construction basically at present, i.e. the cooling of frozen food provides cold by refrigerator refrigeration system fully; When the winter of cold, outer atmospheric temperature fully can frozen food, refrigerator was placed on the indoor consume electric power that still needs and freezes to guarantee that food meets the requirements of temperature in the refrigerator, causes the waste of the energy.
Summary of the invention
The low-temperature receiver that enough low temperatures are arranged around the objective of the invention is in the refrigerator storeroom, refrigerator itself can stop refrigeration, and low-temperature receiver cools off food in the refrigerator outside the refrigerator and utilize, thereby realize the purpose of environmental protection and energy saving.
A kind of energy-saving refrigerator based on existing frostless wind cooling refrigerator, also comprises: cold wind air inlet duct, cold wind exhaust passage, outdoor temperature sensor, air inlet duct air door, exhaust passage air door and refrigerator control panel;
At freezer compartment of refrigerator the cold wind air inlet duct is set at the back, the two ends of cold wind air inlet duct are communicated with refrigerator inside and outdoor cold air, and the cold wind air inlet duct is positioned at the outer end of casing and connects the outdoor temperature sensor, and the cold wind air inlet duct is provided with the air inlet duct air door at the casing place;
Refrigerator body lower bottom steel plate corresponding position is provided with the cold wind exhaust passage, and cold wind exhaust passage one end is communicated with refrigerating chamber, and the other end connects the exhaust passage air door, makes refrigerating chamber be communicated with extraneous air through the cold wind exhaust passage;
The refrigerator control panel connects outdoor temperature sensor, refrigeration sensor, freezing sensor, air inlet duct air door and exhaust passage air door, and the refrigeration sensor connects the refrigeration air door, and freezing sensor connects compressor and freezing blower fan;
Described refrigerator control panel is when temperature sensor detects outdoor temperature and is lower than design temperature out of doors, and the control compressor quits work, and simultaneously, opens air inlet duct air door and exhaust passage air door; Freezing blower fan rotates, and cold outdoor air is introduced from the air inlet duct air door, through the distribution of freezing blower fan; Cold air is divided into two-way, and one the tunnel gets into the refrigeration air channel, gets into refrigerating chamber then; Flow to evaporimeter in refrigerating chamber circulation back from the refrigeration air-return duct, get back to freezing blower fan place then, accomplish refrigeration cycle; Another road gets into freezing air channel, gets into refrigerating chamber then, in freezing indoor circulation, is discharged to the open air through the cold wind exhaust passage then, and refrigerator is accomplished whole wind path circulations;
When the outdoor temperature sensor detected outdoor temperature and is higher than design temperature, refrigerator control panel control air inlet duct air door and exhaust passage air door were closed, compressor starts work, and refrigerator normally freezes.
The invention has the advantages that:
The present invention makes full use of the low-temperature receiver of outdoor low temperature air as indoor refrigerator under the prerequisite that guarantees the food storing temperature, compressor quits work in the process of refrigerastion, thereby realizes that refrigerator is energy-conservation significantly, significantly reduces the product noise; In addition, when not having satisfied low temperature cold source in the external world, refrigerator still can adopt the refrigeration system of refrigerator itself to obtain low-temperature receiver as other wind cooling refrigerator.

The specific embodiment
To combine accompanying drawing and embodiment that the present invention is done further detailed description below.
A kind of energy-saving refrigerator of the present invention on the basis of existing frostless (air-cooled) refrigerator, also comprises cold wind air inlet duct 3, cold wind exhaust passage 8, outdoor temperature sensor 4, air inlet duct air door 6, exhaust passage air door 9 and refrigerator control panel 15.
In freezer compartment of refrigerator 1 back cold wind air inlet duct 3 is set; The two ends of cold wind air inlet duct 3 are communicated with refrigerator inside and outdoor cold air; Cold wind air inlet duct 3 an end of refrigerator inside be positioned at freezing blower fan 13 under, cold wind air inlet duct 3 is positioned at the outer end of casing and connects outdoor temperature sensor 4, between cold wind air inlet duct 3 and outdoor temperature sensor 4, airstrainer 5 is set; Airstrainer 5 is used to purify the cold wind that gets into refrigerator, and cold wind air inlet duct 3 is provided with air inlet duct air door 6 at casing 12 places;
