Description

Drying apparatus and drying method

The present invention relates to a drying apparatus and method, and in more detail, to improve the problem that the laundry is damaged due to high heat, and relates to a more efficient drying apparatus and method.

1 is a structural diagram schematically showing a conventional drying apparatus.

Referring to Figure 1, a conventional drying apparatus includes a drum (10) containing laundry to be dried; A fan (20) for suction-circulating medium-temperature wet air in the drum (10) due to the laundry; A heat exchanger (30) for converting the sucked middle temperature wet air into dry air; A heater 40 for heating the low temperature dry air and converting the low temperature dry air into high temperature dry air; It consists of an air pipe 80 that serves as the passage of air.

In more detail, the drum 10 is a member for storing laundry to be dried, and a baffle is formed therein so that the laundry can be lifted by rotation.

The fan 20 is a member that causes the flow of air by rotation, and mainly uses the fan motor 50 as a driving source for high speed rotation. In addition, when the fan 20 and the fan motor 50 are spaced apart by a certain degree, the fan 60 is connected using the belt 60.

The heat exchanger 30 is a member that sucks outside air to cool the middle temperature wet air of the drum 10 introduced by the fan 20 to cool the middle temperature wet air. Cooling fan 31 is provided to suck the water. At this time, the driving source for rotating the cooling fan 31 is to serve as the fan motor 50.

The heater 40 is a member for heating the low temperature dry air dehumidified in the heat exchanger 30 to convert the high temperature dry air.

The air pipe 80 is a member that serves as a passage through which air is circulated, and a drain hole for draining water generated in the heat exchanger 30 is formed, and a drip tray 70 receiving the drained water is separately installed. .

Referring to the operation of the conventional drying apparatus having such a structure, first, the fan 20 rotates at a high speed to suck air in the drum 10. The air is dehumidified while passing through the heat exchanger 30 and becomes hot air by the heater 40 to be supplied to the drum 10 again. At this time, the laundry in the drum 10 is lifted by the baffles formed therein and falls off from the top due to the slow rotation. At this time, the moisture is evaporated by the hot air and the moisture is discharged through the exhaust port.

However, such a drying method has a problem that the production cost is increased by using a heater of a very high temperature, not only the drying efficiency is lowered and the fabric is damaged, but also internal heat resistant material must be used.

In addition, since its use is incompatible with the drum, there are many problems in application.

The present invention has been made to improve the above problems, and an object of the present invention is to provide a drying apparatus and method which can dry laundry more efficiently at a lower temperature than a heater and can be variously applied.

Referring to FIG. 2, the drying apparatus according to the present invention includes an evaporator 210 for converting air of a predetermined space into low temperature dry air, a condenser 230 for converting low temperature dry air into high temperature dry air, and the various states. The fan 250 for circulating the air is provided, and generally consists of the refrigeration means 200 is modular so that the laundry can be used alone to separate from the drum 100 containing the laundry.

In more detail, the evaporator 210 is a member in which a low temperature low pressure liquid refrigerant is converted into a low temperature low pressure gas refrigerant, and thus absorbs ambient heat when the refrigerant evaporates, resulting in lowering the ambient temperature. do. At this time, the air introduced by the fan 250 is present, the temperature is lowered due to the evaporator 210 and the relative humidity is raised to form water. As a result, dehumidification occurs and the incoming air is replaced with cold, dry air.

The condenser 230 is a member in which the high temperature and high pressure gas refrigerant is converted into a medium temperature and high pressure liquid refrigerant, and emits heat to the surroundings when the temperature of the refrigerant decreases, thereby increasing the ambient temperature. At this time, there is a low-temperature dry air passed through the evaporator 210, the temperature rises due to the condenser 210 is changed to high-temperature dry air.

The evaporator 210 and the condenser 230 should be continuously supplied with air to be used for heat exchange, and for this purpose, an evaporation fan and a condensation fan are required.
