The solvent of the solvent storage tank 21 below the laundry chamber 11 is supplied to the pipeline 12 in the laundry chamber 11 by the solvent circulation pump 24 through the solvent supply pipe 22, and the pipeline 12 The solvent is injected into the laundry room 11 through a plurality of spray nozzles 13 attached to the.

The pipeline 12 installed inside the laundry room 11 is formed of a plurality of lines on the side surface, the upper and the lower surface of the laundry room 11, and the solvent is attached to the laundry through the nozzle 13 attached to the pipeline 12. It is sprayed to wash the laundry.

In the present invention, the laundry is preferably hung on a hanger provided in the laundry room.

The solvent washing the laundry in the laundry room 11 is collected by falling into the collecting plate 14 of the bottom of the laundry room 11, the solvent recovery pipe 25 connecting the collection pipe 14 and the solvent storage tank 21. It is transferred to the solvent storage tank 21 through.

After the laundry in the laundry room 11 has been washed with the solvent, the valves 25-1 and 22 of the solvent supply pipe 22 for supplying the solvent to the laundry room 11 and the solvent recovery pipe 25 for recovering the solvent are provided. -1) (22-2) and (22-3), the lock is blocked to supply the solvent, and the laundry room 11 is subjected to hot air to perform a laundry drying process, the next step.

In the present invention, the main heat source applying hot air to the laundry room is a dry air generated in the freezing cycle as the main heat source, and the electric heater 45 is used as an auxiliary heat source.

That is, the exhaust air containing the moisture discharged through the hot air exhaust pipe 41 connected to the upper laundry room 11 is partially separated through the water separator 51, and the dry air partially separated from the air is Almost most of the moisture is removed from the first heat exchanger 31 and the evaporator 32, heated through the second heat exchanger 33 and the condenser 34, and is heated through the hot air supply pipe 43. It is introduced into the pipeline 12 and injected into the nozzle 13 to dry the laundry.

As described above, the freezing cycle of the present invention for generating a dry air into the laundry room 11 and supplying hot air to the laundry room will be described in detail.

The refrigerant gas compressed by the compressor (38) is heated to about 90 to 98 ° C. (R 22), and the elevated refrigerant gas is transferred to the condenser 34 to pass through the condenser 34. The air is heat-exchanged, heated to about 50-55 ° C., supplied to the internal and external pipelines 12 through the hot air supply pipe 43, and then sprayed onto the nozzles 13 to dry the laundry in the laundry room 11. Let's go.

The refrigerant gas heat-exchanged in the condenser 34 is introduced into the first receiver 36 and then cooled while passing through the expansion valve 32-1. That is, the refrigerant gas through the expansion valve 32-1 is cooled to -10 ~ -20 ℃ at the same time as the high pressure refrigerant is reduced to low pressure is introduced into the evaporator (Evaprtator) (32).

The evaporator 32 cooled to -10 to -20 ° C aggregates moisture in the hot exhaust air in the washing chamber 11 transferred through the hot air exhaust pipe 41 to generate condensed water to convert wet air into dry air. It will remove moisture.

In addition, the condensation water generated in the evaporator 32 is collected by the condensation collecting plate 61 and is transferred to the solvent storage tank 21 through the condensation collection tube 62.

As described above, the low temperature evaporator 32 not only cools the moisture in the exhaust air but also cools the solvent gas contained in the exhaust air, aggregates it into condensation water together with the moisture, and the solvent storage tank through the condensation recovery tube 62. It is transferred to 21.

The refrigerant gas in the evaporator 32 is transferred to a compressor 38 through a second receiver (receiver) 39, is heated by compression, and is transferred to a condenser 34 to generate a refrigeration cycle. Will perform.

The temperature of the exhaust air passing through the evaporator 32 is reduced by about 30%. That is, after passing through the evaporator 32, the temperature of exhaust air to 40-42 degreeC will fall to 30-33 degreeC, and the moisture in exhaust air will condense and aggregate.

In the above, the exhaust air flowing into the evaporator 32 must be cooled in advance through the first heat exchanger 31 to lower the heat exchange rate of the refrigerant generated in the evaporator 32, thereby reducing the operating load of the compressor 23. Let's go. If the first heat exchanger 31 for cooling the evaporator 32 is not installed, an external heat exchanger for cooling the evaporator 32 is required.

As such, the wet air transferred from the laundry room 11 through the hot air exhaust pipe 41 is dried and dried while passing through the first heat exchanger 31, the evaporator 32, the second heat exchanger 33, and the condenser 34. , Heated to 50 ~ 60 ℃ is transferred to the pipeline 12 of the laundry room 11 through the hot air supply pipe 43, is sprayed to the nozzle 13 to dry the laundry.

It is installed to increase the efficiency of the refrigeration cycle.

That is, the first heat exchanger 31 installed in front of the evaporator 32 lowers the temperature of the exhaust air introduced into the evaporator 32, thereby reducing the temperature of the refrigerant on the evaporator 32, thereby allowing the compressor 38 to cool the refrigerant. Compression reduces the operating load of the compressor 38 when high heat is generated to serve to protect the compressor.

As such, when the compressor 38 compresses the refrigerant to generate high heat (90 to 98 ° C.), the compression efficiency of the compressor 38 is increased, and the first heat exchanger 31 serves as a protection of the compressor 38. Cooling the 32 to enable a high efficiency operation of the compressor, the refrigerant in the condenser 34 is to heat the exhaust temperature passed by passing the heat to 50 ~ 60 ℃ to transfer to the hot air supply pipe (43).

The exhaust air passing through the condenser 34 condenses water and solvent gas remaining therein in the second heat exchanger 33 and the evaporator 32 and aggregates into condensed water to form the second heat exchanger 33 and the evaporator 32. After being collected by the condensation collection plate 61 of the lower portion is transported to the solvent storage tank 21 by the condensation recovery pipe 62.

In the laundry room of the present invention, a plurality of ultrasonic generators 11-1 generating ultrasonic waves (1 to 3) may be fixed.

The ultrasonic generator vibrates the sprayed solvent in the laundry to increase the washing power, and serves to promote washing to quickly decompose the oil when concentrated in the laundry into the solvent by ultrasonic vibration.

As the present invention is seen in a normal washing machine, the washing process, the present invention is to perform the drying and the wrinkle removal process in the laundry at the same time or partially perform each process.

In the laundry room 11, the solvent is sprayed to the laundry to remove the water-soluble to oil-soluble foreign matter contained in the laundry, and then the refrigeration cycle is operated to supply the continuous hot air into the laundry room to supply laundry. Moisture is evaporated to carry out the drying process,

By supplying steam (steam) into the laundry room, the laundry finishing process (an ironing process) of removing the wrinkles of the laundry can be performed in a batch.

The present invention is not possible to wash at home, such as silk, silk, leather clothes can be seen that the effect of performing a high-quality cloth material was washed in a short time directly at home to the laundry.

According to the present invention, the washing process, the drying process, and the wrinkle removal process by steam may be selectively performed to selectively dry the laundry according to the type of the cloth. The effect of saving washing time can be seen.

The present invention has the effect of removing the static electricity and rinse effect of the clothes by heating the steam, the sterilization effect can be seen to be able to see the effect of obtaining sterilized clothes.
