Description

The refrigerated dehumidification dryer

The utility model relates to refrigeration and dry technology, belongs to daily necessities, is meant the refrigerated dehumidification dryer especially.

Existing dryer, generally be to adopt electrically heated hot air type dryer, be about to outside air and introduce the heating clamber of dryer, air improves temperature through heating, make air be undersaturated condition, at this moment the dividing potential drop of water in air vapour is lower than the saturated vapor pressure under synthermal, and hot-air enters the hothouse of dryer then, takes the moisture of wet wash out of dryer by the hot-air that humidity is less.Dryer according to this principle is made in order to obtain bigger drying effect, just requires higher air themperature.Drying temperature height, not only power consumption is big, and face and clothing had damage particularly for high-grade clothings such as woollen fabrics, silk goods, easily causes contraction distortion, and adverse consequences such as fiber embrittlement cause the universal of hot wind clothing dryer of Electric heating to be restricted.

The purpose of this utility model is to overcome the disadvantages of background technology part, and the refrigerated dehumidification wardrobe formula dryer of low, the closed no moisture of a kind of drying efficiency height and power consumption, simple in structure, safe in utilization, suitable any clothing is provided.

The purpose of this utility model will reach by following measure:

The refrigerated dehumidification dryer, in the closed system that the shell made from metal or plastics, insulating sandwich and hermatic door constitute, be provided with the drying chamber that has clothes hanger, dry air import and humid air outlet, be equipped with that finned refrigerant condensation is comb forms the steam condensation chamber with heating clamber axial flow blower and by servicing units such as finned refrigerant evaporation comb and separator, drip tray, water receiving jars; Heating clamber links to each other with the dry air import of drying chamber, and compressor outlet is connected with refrigerant condensation comb, and the suction side is connected with the refrigerant evaporation comb, and what communicate with an end of steam condensation chamber is the humid air passageway that links to each other with dryer humid air outlet; The other end of steam condensation chamber communicates with the axial flow blower suction inlet, is provided with dividing plate between steam condensation chamber and the compressor.

The principle of refrigerated dehumidification clothes dryer is, the high pressure refrigerant that relies on the refrigeration compressor working face to obtain becomes gaseous state through throttling expansion in the refrigerant evaporation comb, conduct heat by fin simultaneously and absorb the heat of surrounding environment, humid air temperature in the steam condensation chamber is descended, contained moisture content is supersaturation and condenses into water droplet in the air, isolate moisture through separator, dewatered dry air by axial flow blower to heating clamber.Refrigerant low-pressure gas after the expansion becomes gases at high pressure by compressor compresses, and gases at high pressure are emitted heat and are condensed into liquid coolant.This part condensation heat of emitting is passed to dry air by refrigerant condensation comb and fin thereof makes drying-air temperature reach 36～38 ℃, becomes unsaturated heated dry air, is blown into the drying chamber by the dry air import, is used for drying clothes.Moisture in the wet wash because of hot blast temperature and with dry air in the difference of different steam partial pressure evaporate, the part moisture face that dry air has carried wet wash becomes humid air, enter the humid air passageway by the humid air outlet and get back to the steam condensation chamber, constitute totally enclosed gas-circulating system.Air is constantly taken away the moisture in the wet wash through constantly circulation, transfers in the water receiving jar, reaches the purpose of drying.

The utility model is compared with background technology, and following outstanding advantage is arranged:

1, energy consumption is low.The electric energy of this machine consumption is used for drive compression machine and axial flow blower, and the power consumption of the high-power heater that adopts with the hot air type dryer differs greatly.And the heated dry air temperature that this machine adopted is low, has a narrow range of temperature with surrounding environment, and the heat loss that causes is few.And the energy loss that the high temperature air of hot air type dryer and the surrounding environment temperature difference cause greatly is also big.

2, because this dryer is full closeding state, solved the insurmountable humid air problem of environment pollution caused of hot air type dryer.

3,,, exempted clothing crumple after the tumbler dryer drying and needed the trouble of flatiron for the usefulness of clothing suspensions because the drying chamber is provided with clothes hanger.

4, with respect to the hot air type dryer, the utility model belongs to low temperature drying, avoided the damage that causes because of the high temperature air drying to clothing, particularly aging worry to high-grade clothing contraction distortions such as woollen fabrics, silk goods, embrittlement, make the dryer scope of application more extensive, accepted easilier by users.

Accompanying drawing is the structural representation of refrigerated dehumidification dryer.

With the enforcement side the utility model is described in further detail in conjunction with the accompanying drawings:

As the described refrigerated dehumidification dryer of accompanying drawing, be provided with one and have clothes hanger 3 and have dry air import 16 and the drying chamber 5 of humid air outlet 4 in the closed system that casing 1 and insulating sandwich 2 are constituted, what communicate with the drying chamber is that the refrigerant condensation comb 15 of band fin 8 and the heating clamber of axial flow blower 14 are housed.What be connected with refrigerant condensation comb is the port of export of compressor 13, the suction side of compressor 13 is connected with the refrigerant evaporation comb 7 of band fin 8, the steam condensation chamber that servicing units such as refrigerant evaporation comb 7 and separator 9, drip tray 10, water receiving jar 11 are formed.What communicate with an end of steam condensation chamber is and the dryer humid air outlet 4 humid air passageways 6 that are connected, and the other end of steam condensation chamber communicates with the axial flow blower suction inlet, and steam condensation chamber and compressor separate with heat insulation clamping plate 12.17 is hermatic door.

Connect power supply, axial flow blower 14 starts, and after refrigerant condensation comb 15 heating of dry air in heating clamber, is blown into drying chamber 5.Hot-air is taken the part moisture in the indoor wet wash of drying out of the drying chamber, becomes humid air, and humid air 6 arrives the steam condensation chambers by humid air outlet 4 through the humid air passageway.And the high pressure refrigerant liquid that links to each other with compressor 13 expands in refrigerant evaporation comb 7 and evaporates through throttling expansion, the heat around sucking simultaneously.Temperature in the steam condensation chamber is descended, and the moisture in the humid air is hypersaturated state and condenses into water droplet, and separated going out behind separator 9 breaks away from this dryer through drip tray 10 and water receiving jar 11 again.The dry air that is removed moisture is introduced heating clamber by axial flow blower 14.Refrigerant low-pressure gas after compressor will evaporate sucks, and the compressed gases at high pressure that become are emitted heat and become liquid in refrigerant condensation comb 15.The condensation heat of emitting is just passed to dry air by the refrigerant condensation comb that has fin, and drying-air temperature rises to 36～38 ℃.Enter drying chamber drying wet laundry.So constantly circulation constitutes totally enclosed gas-circulating system, constantly the moisture in the wet wash is taken away, and constantly with condensate moisture and separate, reaches the purpose of drying in the steam condensation chamber.

After washing machine dries, but 4 kilograms of wet washs were through 150～180 minutes bone dries, and total power consumption is 0.7～0.8 degree, knows the clothing with the dry same amount of existing hot air type dryer, total burn-off is 2.2～2.6 degree, adopts the utility model to economize on electricity more than 50%.
