Description
Technical field
The present invention relates to the quick-freezing plant of the refrigerator in a kind of mechanical engineering refrigeration or cooling field refrigerator, refrigerator, cooling or the refrigerating plant, particularly relate to a kind of refrigerating chamber and mark off and be provided with the quick-frozen chamber that has the cold air guide channel in addition at refrigerator, and can improve freezing efficiency, thereby the quick quick-frozen of the food that is stored at the quick-frozen chamber can be had the quick-freezing plant (APPARATUS FOR QUICK FREEZING OFREFRIGERATOR) of the refrigerator that can better keep original taste of food and the good effect of nutritional labeling.
Background technology
Under normal conditions, refrigerator generally is to be divided into refrigerating chamber two parts of preserving the refrigerating chamber of ice maker container and frozen food and can take in the refrigeration object under the temperature of setting.Portion and be provided with freezing cycle device within it, carry out freeze cycle in four kinds of modes such as compression, condensation, expansion, evaporations, and utilize the evaporimeter in the closed circuit can absorb freezing, the frozen state that this architectural characteristic of outside heat keeps refrigerator inside.Existing traditional refrigerator generally is to adopt the frame mode that refrigerating chamber is arranged on refrigerating chamber top, and large-scale refrigerator capacious, then be to adopt the parallel construction mode (side by side type) that is provided with about refrigerating chamber and refrigerating chamber be designed to mostly, so that can preserve the more food of volume.
The freezing cycle device of refrigerator as previously discussed, it comprises: the gas shape refrigerant of compression low temperature, low pressure, and with the compressor of the gaseous state refrigerant output of high temperature, high pressure; Utilize the refrigerant of the gaseous state of high temperature that extraneous air produces above-mentioned compressor, high pressure to cool off, condensation, make it reach the condenser of liquefaction; The capillary of the refrigerant decompression output of the highly pressurised liquid state that above-mentioned condenser is produced; Introducing is absorbed heat in the low-temperature evaporation mode under low-pressure state from the refrigerant that is depressurized of above-mentioned capillary generation, constitutes and reach the evaporimeter that cools off purpose.
Particularly, air cooling formula refrigerator, it is provided with the fan used of discharging cold air, can be with the cold air drainage of above-mentioned evaporimeter periphery to above-mentioned refrigerating chamber and refrigerating chamber inside with the cooling refrigerator, and regulate temperature in the refrigerator by the driving of control device control said fans and compressor.
Refrigerator for the temperature of controlling above-mentioned refrigerating chamber and refrigerating chamber respectively, it also drives respectively and controls the fan of cold air drainage to above-mentioned refrigerating chamber and refrigerating chamber, and utilize fan with the cold air drainage around the above-mentioned evaporimeter to refrigerating chamber and refrigerating chamber, with the assigned temperature in the maintenance refrigerator.
And, because food its taste and nutritional labeling when freezing is destroyed easily, thus to carry out quick-frozen when food freezed, with taste and the nutritional labeling that keeps the food initial stage to the full extent.
Again, the temperature range of the most of moisture that can freeze in the food fully to be comprised is spent-5 degree for-1, the quality that roughly about this temperature range, can well keep food, carry out quick-frozen so dwindle as much as possible, can keep the fresh quality of food to greatest extent at this interval freeze-off time.
But, be not provided with the quick-frozen chamber that quick-frozen is used in addition because have the inside of the refrigerating chamber of traditional refrigerator now, more out of the question be provided with feedway, so can produce ruined problems such as taste of food and nutritional labeling to this other cool-air feed in quick-frozen chamber.
This shows that the refrigerating chamber of above-mentioned existing refrigerator still has many defectives, and the assistant officer treats further to be improved.
Because the defective that the refrigerating chamber of above-mentioned existing refrigerator exists, the inventor is actively studied innovation, through constantly studying, designing based on abundant practical experience and professional knowledge, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
