Description

Refrigerator

Technical field

This utility model is related to a kind of refrigerator, and in particular to a kind of air cooling type refrigerator.

Background technology

Current refrigerator possesses temperature-changing chamber, storeroom and the refrigerating chamber of multiple different temperatures bands, for being changed by single cooler Thermogenetic cold air, is blown respectively using multiple blowing units corresponding with multiple temperature-changing chambers, storeroom and refrigerating chamber.

Application No. 201310504417.7, the patent documentation of entitled refrigerator discloses a kind of multiple exhaust air flue difference Be connected between the refrigerating chamber and the plurality of compartment with by the indoor air of the freezing be sent to it is the plurality of between interior, Multiple air doors are located at the indoor respective end to close off or open the plurality of exhaust air flue of the freezing in which can turn respectively, many The technical scheme that individual air door is controlled by control module, the air door for possessing cut-out air-supply in airduct way, so implement to refrigerating chamber and Operating that cold room is cooled down simultaneously and the operating that refrigerating chamber is individually cooled down.See on existing disclosed technological document, The technical scheme and technical scheme Datong District disclosed in the file of Application No. 201310504417.7 of many airducts or air channel air-supply is little It is different, do not have cold room or refrigerating chamber with regard to improving energy saving individually to cool down the record of operating, do not have with regard to implementing cold preservation yet The record of the flowing of the cold air of cold room and refrigerating chamber when room individually cools down operating, while exist can not be accurate between different refrigeration Temperature control, the problems such as compressor continuous working period length is unfavorable for defrost.

The content of the invention

A kind of targeted above-mentioned technical problem of this utility model, there is provided temperature that can be precisely controlled each cool room, steams Sending out the cold of device can make full use of, while reducing the compressor operating time, shortening the defrost cycle, and can reduce power consumption and improve The refrigerator of efficiency grade.

This utility model solves above-mentioned technical problem, there is provided a kind of refrigerator, including control module, air channel module and and at least The cool room of more than 2, the air channel module include vaporizer, be arranged on vaporizer side blower fan, for cool room air-supply Several blowing units；Described blowing unit includes air channel, air outlet and return air inlet；Described each cool room is independent by one Blowing unit air-supply, described blowing unit all individually blown by the blower fan of an independent control.Blower fan is arranged on vaporizer Side, aspirates from cool room backflow to come and carried out the air-flow of heat exchange with vaporizer, is then fed into blowing unit In air channel, Jing air outlets enter into cool room, and each cool room has independent blowing unit, and is blown by independent blower fan, The actual demand that control unit is fed back according to cool room controls the operating of blower fan so as to adjust the conveying of cold, makes each freeze Room can flexibly control temperature.At least two during refrigeration, single cool room does not embody the beneficial effect of the technical program, Cool room is more more more can embody the beneficial effect of the technical program, and cool room can be 2, or 3, or 4 Individual even more many, several cool rooms of usual refrigerator cover cold room, refrigerating chamber and also have temperature-changing chamber.Because blower fan just can be with speed change Adjustment air quantity, blowing unit is sent to the air quantity of each cool room without the need for adjusting by air door.Blowing unit is sent by independent blower fan Wind, with respect to the whole refrigeration system of refrigerator for, realize local directed complete set so that the cold of vaporizer is fully used, press Contracting machine also can reduce the working time, therefore can also slow down the freezing time of vaporizer, and causing the cycle time of defrost also can shorten, And then greatly reduce power consumption, reducing energy consumption, improving energy efficiency grade.

Further, described cool room is respectively cold room, refrigerating chamber and temperature-changing chamber, and corresponding blowing unit is only respectively Stand as its cold preservation air-supply, freezing air-supply and alternating temperature air-supply.The temperature that cold room, refrigerating chamber and temperature-changing chamber are required respectively is different, Control module adjusts the air quantity of blowing unit according to temperature and air quantity demand, realizes the temperature requirement of different type cool room.

Further, described blower fan is centrifugal blower.Centrifugal blower has air quantity big, and axial length is short, takes up room Little the characteristics of, the air quantity of heat exchange can be increased in the narrow space of vaporizer side, improve heat exchange efficiency.

Further, described refrigeration unit is provided with multiple air outlets in refrigeration interior, and each air outlet is designed with independence The airdoor control air quantity of switch.Air outlet can be arranged on the same wall in cool room inside or on different walls, cool room It is interior that septalium can be set, one cool room is divided into into the multiple refrigeration areas with multiple temperature provinces by disposing dividing plate, The different refrigeration area of different air outlet correspondences, you can the accurate temperature controlling to the indoor difference warm area of refrigeration, is more beneficial for article Cold preservation, freezing or alternating temperature.Air door is arranged in air outlet to be only intended to freeze the fine tune temperature of indoor zones of different, relative to whole For cool room, again blower fan air output is adjusted cryogenic temperature.

Compared with prior art, this utility model enables each cool room flexibly to control temperature, allows the cold of vaporizer Amount is fully utilized, and compressor also can reduce the working time, therefore can also slow down the freezing time of vaporizer, causes defrost Cycle time also can shorten, and then greatly reduce power consumption, reducing energy consumption, improving energy efficiency grade.
