The control method comprises the following steps: an axial flow fan is started when the temperature of a refrigerating chamber is higher than 4 DEG C; air in the refrigerating chamber is sucked by the axial flow fan through a normally open valve body of an air-inlet two-position three-way electromagnetic reversing valve; then, the sucked air is supplied to metal cold-scattering U-shaped pipes where evaporator coils are wrapped, so as to melt frost on the outer surfaces of the metal cold-scattering U-shaped pipes; water vapor in the air supplied to the metal cold-scattering U-shaped pipes is cooled and condensed into water, and a lot of heat is released; condensate water flows into a water collecting tank through a water drainage pipe; cold air from all the metal cold-scattering U-shaped pipes enters a refrigerating chamber air-inlet pipe and the refrigerating chamber through a plastic air-outlet main and a normally open valve body of an air-outlet two-position three-way electromagnetic reversing valve, so as to cool the air in the refrigerating chamber; when the temperature of the refrigerating chamber is lowered to 0 DEG C, the two two-position three-way electromagnetic reversing valves are powered on; and the cold air in the metal cold-scattering U-shaped pipes is supplied by the axial flow fan to a foamed plastic heat-preservation layer.
Description
Technical field：
The present invention relates to a kind of energy-saving electric refrigerator cold scattering defroster and control method.
Background technology：
Samsung of Korea S has applied for patent of invention in nineteen ninety-five《The defroster of refrigerator and its control method》.It
Structure is as follows：Equipped with an electric fan in left side interlayer between refrigerator inner casing and shell, refrigerating chamber inner left wall has one
Bar horizontal gap, inwall on the right side of refrigerating chamber also has a horizontal gap, in the left side of be aligned three anxious jelly room evaporator coil
Three horizontal gaps are had on wall, the right side inwall of be aligned three anxious jelly room evaporator coil also has three horizontal gaps.Electric ice
Horizontal gap from refrigerating chamber inner left wall for the electric fan in left side interlayer between case inner casing and shell is 4 DEG C in refrigerating chamber
Hot-air is extracted out, and three horizontal gaps from three anxious inner left wall freezing room evaporator coil of be aligned are blown into suddenly freezes room,
Three anxious frost fusings frozen on the evaporator coil of room, then suddenly freeze the indoor cold air less than 0 DEG C and suddenly freeze rooms for three from be aligned
Three horizontal gaps on the right side inwall of evaporator coil enter in right entrance right side wall interlayer, then inwall on the right side of refrigerating chamber
On horizontal gap enter refrigerating chamber.Existing have the artificial defrosting of each moon of white refrigerator once：The anxious food freezing in room
Transfer in refrigerating chamber, pull out the power-line plug of refrigerator, allow refrigerator to have a power failure 12 hours, three anxious jelly room evaporator plates
Manage all to melt with the frost on cold scattering wing bar and fall in three anxious jelly room boxes, fall into the water suddenly freezing in the box of room more than one
Jin.Namely three urgency freeze the frost that on room evaporator coils and cold scattering wing bar, every day is tied 20 grams, does not carry on a shoulder pole in summer
Heart compressor each and every one hour every is run once, and the frost that frozen each time is close to two grams.The heat of fusion of frost be 80 cards/gram.Fusing
Two grams of frosts need 160 card heats.Less than one cubic metre, the proportion of air is 1.29 grams every cubic metre to the volume of refrigerating chamber, cold
Hide indoor air less than one gram.The specific heat of air be 0.7 card/gram, in refrigerating chamber, 4 DEG C of air drops to 0 DEG C of heat being discharged
Amount is less than 3 cards.After compressor for refrigeration runs once, the electric fan in left side interlayer between refrigerator inner casing and shell runs ten
The air of 44 DEG C in secondary, refrigerating chamber drop to 0 DEG C ten times, do not melt compressor for refrigeration yet and run and once anxious freeze rooms at three
Frost is frozen on evaporator coil and cold scattering wing bar close to two grams.It is to rely on that the existing refrigerating chamber having white refrigerator reduces temperature
One connection refrigerating chamber and the hole of anxious one centimetre of diameter freezing room, refrigerate the indoor hot-air higher than 0 DEG C and are less than 0 DEG C with anxious jelly room
Cold air convection carry out heat exchange.When the temperature of refrigerating chamber is more than 4 DEG C, just start the compressor of refrigerator, Zhi Daoleng
It is just out of service that the temperature of Tibetan room is reduced to 0 DEG C of compressor for refrigeration.The absolute humidity of the air in refrigerating chamber is higher than anxious jelly room
In air absolute humidity, so the air of refrigerating chamber enters anxious after freezing room, a part of water vapour in air can coagulate to the cold
Form water fall three anxious freeze on room evaporator coils and cold scattering wing bar, then further three anxious freeze room evaporator coils and
Frost, the refrigerating capacity of consumption refrigerator are formed on cold scattering wing bar, one gram of water vapour forms the heat of frost release more than 400 cards heat
Amount.After the relative air humidity of refrigerating chamber reduces, just have the food in refrigerating chamber and evaporate water vapour as supplement, make food
Become dry, lose feeling of freshness.
