The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 is the front elevation that cold air supply device is set, and Fig. 4 is the refrigerator cross-sectional side view of Fig. 3.By Fig. 3 and Fig. 4 as can be known, the refrigerator of the dehydrating unit of setting of the present invention be by casing 1, by with casing 1 form refrigerating chamber 10 and refrigerating chamber 20, the refrigerating chamber door 11 that is arranged on casing 1 front switch refrigerating chamber 10 and switch refrigerating chamber 20 that the dividing plate 16 of one divides cold sotrage door 21, provide the freezing cycle device of cold air to constitute for refrigerating chamber 10 and refrigerating chamber 20.
Refrigerating chamber 10 comprises the cooling chamber 2 of screen board 14 divisions that are arranged on refrigerating chamber door 11 rightabout rear sides, in cooling chamber 2 inner space width and the corresponding big or small inner space of thickness, evaporimeter 3 is set, and the required cold air of generation refrigerator inside, blowing fan 13 is arranged on the upside of evaporimeter 3, the cold air forced flow that evaporimeter 3 is produced, at the flow of the front of blowing fan 13 control cooler, and the delivery outlet grid that communicates with refrigerating chamber of setting.
The a plurality of interlayer boards 22 of refrigerating chamber 20 usefulness are arranged to sandwich construction, for in refrigerating chamber 20, placing food, cold air guiding channel 15 is located at the back side of refrigerating chamber 20, the cold air that guiding evaporimeter 3 produces is by refrigerating chamber delivery outlet 15a, output to refrigerating chamber 20 inside, the back side that cold air suction passage 23 is located at refrigerating chamber 20 sucks cold air, and cold air is guided to evaporimeter 3 sides cools off, dehydrating unit 24 is arranged on the inside of cold air suction passage 23, removes the moisture in the cold air.
After the refrigerator energising, be arranged on the inner compressor that constitutes kind of refrigeration cycle the gas refrigerant of low-temp low-pressure is compressed into the gas refrigerant of HTHP, and the gas refrigerant of this HTHP is condensed into the liquid refrigerant of HTHP during by condenser.
The liquid refrigerant of HTHP is through becoming the liquid refrigerant of low-temp low-pressure behind the expansion valve, be evaporated through becoming the gas refrigerant of low-temp low-pressure behind the evaporimeter 3 again, and, make ambient air by heat exchange by the evaporation of evaporimeter 3, produce cold air thereby become cold air.
As above the cold air of Chan Shenging by the rotation of the blowing fan 13 that is arranged on casing 1 back side upside, forces to deliver to the cold air distributor chamber.Be fed in the refrigerating chamber 10 by refrigerating chamber outlet 12a afterwards, the food that cooling is preserved is to uniform temperature, and remaining cold air flows into the cold air guiding channel 15 at refrigerating chamber 20 back sides by screen board 14 guiding, is fed to refrigerating chamber 20 inside by refrigerating chamber delivery outlet 15a.
The cold air that flows into from delivery outlet 15a, the food in the refrigerating chamber is cooled to uniform temperature after, flow into the back side suction inlet 23a of refrigerating chamber 20 back underside, flow into once more in the cooling chamber by cold air suction passage 23, cool off again by evaporimeter.Be drawn into the moisture that contains the food of the preserving discharge of refrigerating chamber 20 inner institutes in the cold air in the cold air suction passage 23.
The cold air that contains moisture is through cold air suction passage 23 time because temperature difference, with cold air suction passage 23 join the side of white plate 24a coagulate frost, reduced humidity.And the steam vapour amount on white plate 24a is when acquiring a certain degree, and Defrost heater 24b is being arranged on white plate 24a inside, and Defrost heater 24b starts and produces heat, defrost, and defrost water flows to the outside by storing up white water tray 24c.
In the present invention, after the refrigerated compartment 20 interior foods, when the cold air that temperature and humidity all rises to some extent passes through cold air suction passage 23, the steam that contains in the cold air coagulate frost in cold air suction passage 23 join white plate 24a, through behind the certain hour, Defrost heater 24b starts, and the steam on the white plate 24a is become white water, and flowing to the outside by white water tray, the moisture that therefore arrives in the cold air of cooling chamber 2 decreases.Thus, the cold air that reduces moisture contacts with evaporimeter 3, has reduced the steam vapour amount on the evaporimeter 3, has prolonged defrosting cycle, has improved cooling effectiveness.
