The structure of the utility model is characterized in that the utility model is composed of an air passage, an air passage door, and a cold storage device; the air passage passes through a partition plate between a cold storage chamber and a freezing chamber to communicate the cold storage chamber and the freezing chamber; the air passage door is positioned at an air passage outlet of one side of the freezing chamber; the air passage door is connected with a control terminal of a thermostat of a refrigerator, and is controlled by the thermostat; the cold storage device is positioned at the upper part of the freezing chamber, the cold storage device can store cold and release cold, or the cold storage device is composed of two parts which are respectively positioned at the upper part of the freezing chamber and the side of an evaporator of the cold storage chamber. The utility model has the advantages that the structure is simple; the cost increases less; the utility model can refrigerate food, and the utility model has no noises; the utility model is suitable for placing a refrigerator at any indoor place, such as living rooms, bedrooms, etc.
Description
The utility model relates to a kind of refrigerator attemperator, and particularly a kind of refrigerator is shut down attemperator.The noise reduction technology field that belongs to refrigerator.
In China and other developing countries, present most of people's living space is less, particularly kitchen area is less, a refrigerator is not put in slight kitchen, a lot of people are placed in refrigerator in parlor or the bedroom, because refrigerator can produce noise in running, this noise is especially obvious in the dead of night, and the interference people sleep and have a rest.Though the manufacturer of refrigerator make great efforts to reduce the noise of refrigerator, as long as refrigerator has start, stopping process, or compressor is in running status, and the noise of Chan Shenging all can exist therefrom, have only when compressor really out of service, could thorough elimination noise.Because the refrigerating chamber and the refrigerating chamber of prior art refrigerator all do not store up cool equipment; the cold of food storage is very limited in the refrigerating chamber; the insulating foam layer unreasonable structure, the heat insulation effect that add refrigerator are bad; therefore with the refrigerator dump; after the compressor shutdown; the temperature of refrigerating chamber will rise to very soon and be higher than design temperature, and the food of refrigeration indoor storage will degenerate.Given this, how to make to keep the temperature set in freezer compartment of refrigerator or the refrigerating chamber long period, can not produce noise again, just become the difficult problem that refrigerator system merchant presses for solution.
The purpose of this utility model; be to refrigerate the shortcoming that indoor temperature can not reach design temperature after freezer compressor is shut down in the prior art in order to overcome; provide refrigerating chamber after a kind of compressor shutdown, freezing indoor temperature to keep set temperature value for a long time, muting refrigerator is shut down attemperator.
The purpose of this utility model can reach by taking following measure: refrigerator is shut down attemperator; be positioned at the inner chamber of refrigerator; its design feature is: by ventilating duct; air channel door and regenerator are formed; ventilating duct passes the demarcation strip of refrigerating chamber and refrigerating chamber; be communicated with refrigerating chamber and refrigerating chamber; the air channel door is positioned at the wind passage mouth of refrigerating chamber one side; this air channel door is connected with the control end of the temperature controller of refrigerator and controlled by temperature controller; regenerator is positioned at the top of refrigerating chamber; can save; release cold; perhaps regenerator is made up of two parts, lays respectively at the top of refrigerating chamber; the next door of refrigerator evaporator.
Ventilating duct is with refrigerating chamber, refrigerating chamber is communicated with, when refrigerator energising work, liquid in the regenerator is converted into solid and discharges heat, the savings cold, after refrigerator outage compressor quits work, the temperature that temperature controller detects refrigerating chamber is higher than when setting value, temperature controller control air channel door is opened, because there are the temperature difference in refrigerating chamber and refrigerating chamber, therefore the cold air of refrigerating chamber flows into refrigerating chamber by ventilating duct under the self gravitation effect, and the temperature of refrigerating chamber is descended, when the temperature that detects refrigerating chamber when temperature controller drops to setting value, temperature controller control air channel door is closed, stop cold air to continue to flow into refrigerating chamber, so move in circles, the temperature constant of Keep cool chamber.Owing to regenerator is set in the refrigerating chamber, so refrigerating chamber can continue for some time the supply cold, the size decision of length during this period of time or short storage cold ability by regenerator.
The purpose of this utility model also can reach by taking following measure:
Refrigerator is shut down attemperator, is made up of ventilating duct, air channel door, regenerator and extractor fan, and this extractor fan is connected, is subjected to temperature controller to control with the control end of the temperature controller of refrigerator, and the air channel door is opened, stopped and closing with extractor fan with extractor fan work.
Increase the thickness of the insulating foam layer of refrigerating chamber, refrigerating chamber.
Ventilating duct is arranged at the junction of rear portion, demarcation strip and rear wall of demarcation strip or the junction of demarcation strip and left and right sidewall.
The built-in computer program of refrigerator utilizes this control program to control the downtime of refrigerator.
Compared with prior art, the utlity model has following outstanding advantage:
1. set up regenerator and connect refrigerating chamber, the ventilating duct of refrigerating chamber, air channel door at the inner chamber of the single control of existing two temperature refrigerator, it is structural change, simple in structure, cost increases few, the temperature of refrigerating chamber can keep the design temperature quite a while after compressor quit work, not only can reach the purpose of chilled food, and noiseless, refrigerator can be placed parlor, bedroom etc. Anywhere indoor, and not influence people's sleep, rest.
2. the regenerator that is provided with of refrigerating chamber and refrigerating chamber; it is the basic condition that guarantees to keep for a long time after refrigerator is shut down design temperature; length during this period of time or short except outside the Pass the cold-storage ability with regenerator has; also relevant with the thickness of the insulating foam layer of refrigerator body; if the cold-storage ability of regenerator insulating power enough big, insulating foam layer is strong, just can makes refrigerator shut down the back refrigerating chamber and keep design temperature to reach more than 8 hours.
