DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a heat pump type clothes dryer for drying damp clothes such as washed clothes.

The construction of a conventional example and its problems will be explained with reference to FIGS. 3 and 4 regarding the purchase of a conventionally known clothes dryer.

04 is an exhaust port for discharging internal air to the outside of the main body 101.

When the motor 105 is driven and the engine 109 rotates, the air inside the drum 104 is exhausted to the outside of the main body 101 through the ventilation port 113 and the exhaust port 116, and the inside of the drum 104 is exhausted. The air becomes negative pressure and is sucked from the intake port, and the sucked air is sent to the electric heater 111.
heated by. As the drum 104 rotates, the clothes in the drum 104 are exposed to air heated by the electric heater 111, which draws moisture from the clothes and dries them.

However, in the conventional configuration, since the air is heated using the electric heater 111, the amount of air that can be introduced into the drum 104 is limited, and drying takes a long time. There is a problem in that efficiency is at stake because energy that has been converted into electrical energy is directly converted into thermal energy. Furthermore, since air that has been heated and humidified and has a high enthalpy is exhausted as is, there is a problem of poor energy efficiency.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and aims to improve energy efficiency, shorten drying time, and improve usability.

Structure of the Invention In order to achieve this object, the present invention provides a heat pump type refrigeration cycle and a drum in the main body of the clothes dryer, and sucks the air inside the drum and the air outside the main body into the back of the drum. A blower device for blowing air to the outside of the main body is provided, and the evaporator in the heat pump type refrigeration cycle is provided at an intermediate portion between an intake port and an exhaust port provided at the back of the main body.

With this arrangement, the evaporator recovers energy from the exhausted air and the condenser produces heated air that draws moisture from the clothing.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is the main body, 2 is a drum for storing clothes,
3, 4, and 5 are a compressor, a condenser, and an evaporator, respectively, which constitute a heat pump type refrigeration cycle, and 6 is a liquid receiver. 7
8 is an input port for putting in clothes, 8 is a front door with all input ports, 9 is a front air intake port, and 1o is a filler attached to the front air intake port 9. 11 is a motor that rotates the drum 2; 12 is a fixing plate that fixes the motor; 13
14 is a ventilation hole provided in the drum 2, 14 is a filler provided along the ventilation hole 13, 15 is a filter fixing frame of the filler 14, 16 is a back intake port, and 17 is a back intake port 16. and a blower device provided across the evaporator 5 from the ventilation hole 13; 18 is an exhaust port;
Reference numeral 9 denotes a water tray for receiving condensed water generated in the evaporator.

In the above configuration, when the blower device 17 is operated, air outside the main body 1 is sucked into the main body 1 from the front intake port 9 and the rear intake port 16, and the air introduced from the front intake port 9 is transferred to the drum 2. , the air vent 13 and the evaporator 5 to the outside of the main body 1 from the exhaust port 18, and the air introduced from the rear intake port 16 passes through the evaporator 5 and is discharged from the exhaust port 18.

When the heat pump type refrigeration cycle is operated, the air passing through the front intake port 9 is heated by the condenser 4, and the air exiting from the drum 2 through the ventilation hole 13 is converted into energy by the evaporator 5. be taken away. As the motor 11 rotates, the clothes in the drum 2 have time to remain in the air and are exposed to the heated air created by the condenser 4.

Therefore, by creating heated air and drying clothes using a heat pump type refrigeration cycle, energy efficiency is improved, and assuming the same human power as the heater, the amount of air that can be introduced into the drum 2 can be increased. This has the effect of shortening drying time and improving usability.

Furthermore, since the energy of the air discharged from the drum 2 is recovered by the evaporator 5, energy efficiency is improved.

Effects of the Invention As is clear from the example, the present invention includes a pump-type refrigeration cycle and a drum in the main body of the clothes dryer, generates heated air using a condenser, removes humidity from the clothes, and generates high-temperature air. Since the heat is recovered from the highly humid air using the evaporator, the output for the same amount of human power is increased compared to the evaporator, and a large amount of air can be introduced into the drum, making it easier to dry. This has the effect of reducing the time required, improving usability, and improving energy efficiency.
