(4). need regular defrost, if adopt electricity-heated defrosting then to exist cost height, unsafe factor.
The present invention is directed to the shortcoming of above-mentioned direct-cooling type two-door refrigerator, designed a kind of novel two-door refrigerator refrigeration structure and electric controling mode, have following several advantage:
(1). refrigerating chamber does not have condenser, has saved cost, need not calculate two Room refrigerating capacitys simultaneously and distribute, and helps shortening the refrigerator design cycle, helps refrigerator and develops to top grade.Quality control in helping producing.
(2). winter, use need not add thermal compensation device, saved cost, reduced power consumption.
(3). overcome the shortcoming that general two-door air cooling type refrigerator refrigerating chamber and refrigerating chamber air circulate mutually, the refrigerating chamber of this structure refrigerator and the air of refrigerating chamber can not convection current, make the unlikely taint of odour of food of two Room.
(4). realized the function that refrigerating chamber and freezer temperature can be regulated respectively and control in the direct-cooling type two-door refrigerator.
(5). the mode of two probes of an available electronic temperature control device is controlled temperature, uses two mechanical thermostats to save cost than general air cooling type refrigerator.
(6). the flow through refrigerating chamber outside of the air of refrigerating chamber is equivalent to make the heating of the refrigerating chamber outside, thereby has defrosting effect.
Frame for movement, refrigeration modes and the temperature control mode of this invention are described in detail in detail below.
(1). reserve a fixed gap with the thermal insulation foaming layer and around between the condenser pipe of refrigerating chamber outer wall, the temperature and the refrigerating chamber in this space are close, and therefore, concerning refrigerating chamber, can think a cold air source,
(2). the joint of space and refrigerating chamber has air admission hole and venthole, and two holes all are provided with one-way cock, is provided with supply fan at air admission hole, and during fan work, check valve is by blowing, otherwise closes.
(3). refrigerating chamber and refrigerating chamber all are provided with the temperature controller that can regulate refrigerating chamber and temperature of refrigerating chamber separately, temperature controller is according to variation of temperature start-stop compressor in the refrigerating chamber, temperature in the condensation chamber is remained in the claimed range, according to the variations in temperature start-stop supply fan in the refrigerating chamber, make interior air of refrigerating chamber and the cold air in the above-mentioned space carry out cold and hot exchange, thereby make the refrigeration indoor temperature reach the regulation requirement.
(4). this process is to realize like this, when the refrigeration indoor temperature meets the requirements, supply fan is not worked, air inlet/outlet is closed, make the cold air in the space not carry out cold and hot exchange with the air in the refrigerating chamber, refrigerating chamber does not freeze, and when temperature of refrigerating chamber rising overshoot required, supply fan work blew the air admission hole one-way cock open, to refrigerate room air squeezes in the space, carry out cold and hot exchange back with cold air wherein and discharge from venthole, enter refrigerating chamber, the refrigeration indoor temperature descends, when temperature dropped in the claimed range, fan quit work.When fan work, compressor has work and stops two kinds of situations, and both of these case is the size of cold and hot exchange capacity and do not have the difference of essence concerning refrigerating chamber refrigeration.
