Description

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

Conventional Structure and Problems The structure of a conventional clothes dryer will be explained with reference to FIGS. 1 and 2.

In the figure, 101 is the main body of the clothes dryer, 102 is a front door that opens and closes the input port 103 into which clothes are input, and 104 is a drum that stores the clothes input through the input port 103.
105 is a motor that rotates the drum, 106 is a bearing that helps rotate the drum 104, 107 is a fixture that fixes the bearing 106, 108 is a transmission device that transmits the rotational force of the motor 106 to the drum 104, 109 a fan 110 that is rotated by the motor 105 and sucks air inside the drum 104;
111 is an intake port, and 111 is a connection from the intake port tio to the drum 1.
04 Electric heater that heats the air introduced into the interior, 11
2 is a protective net that prevents clothing from coming into direct contact with the electric heater 111; 113 is a vent hole that allows the air inside the drum 104 sucked by the fan 109 to pass through;
114 is a filter that prevents the ventilation port 113 from being blocked by dust, etc.; 115 is the filter 1;
14 to the drum 104;
Reference numeral 116 denotes an exhaust port for discharging air from the drum 104 sucked by the fan 109 to the outside of the main body 101.

In the above configuration, the motor 105 is driven and 5 fans 1
When the drum 09 rotates, the air inside the drum 104 flows through the ventilation port 113.
The drum 104 is also exhausted to the outside of the main body 101 through the exhaust port 116, the inside of the drum 104 becomes negative pressure, air is sucked from the intake port, and the sucked air is heated by the electric heater 111. When the drum 104 rotates, the drum 104
The clothes inside are exposed to air heated by the electric heater 111, and the heated air removes moisture from the clothes and dries them.

However, the conventional configuration has the problem that the amount of air that can be introduced into the drum 104 is limited because the air is heated using the electric heater 111, and that drying takes a long time. When you think about it, the problem is that it is inefficient because energy that has been converted into electrical energy is directly converted into thermal energy.

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 which a compressor, a condenser, a throttling device, and an evaporator are connected in an annular manner in the main body of a clothes dryer, and the air in the drum is and a blower device for sucking air outside the main body.

With this configuration, the blower sends out the high temperature and humidity air inside the drum to the outside of the main unit, sucks the low temperature and low humidity air outside the main unit into the drum, and the heat pump refrigeration cycle creates high temperature and low humidity heated air. It removes moisture from clothing.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In the figure, 1 is the main body of the clothes dryer, and 2 is a drum for storing clothes. 3 is a compressor, 4 is a condenser, 5 is a throttling device, 6 is an evaporator, and 7 is a receiver, which constitute a heat pump type refrigeration cycle. 6 is a motor that rotates the drum 2; 9 is a sirocco fan that sucks and blows out the air outside the main body jet as well as the air inside the drum 2; 9 is an intake port; 11 is a vent; 12 is the vent a filter for preventing the blockage of the mouth 11; 13 is a filter cover; 1
4 is an air guide, 15 is a water tray for receiving condensed water generated in the evaporator 6, 16 is a clothing inlet, 17 is a front door for opening and closing the inlet 16, and 1Ej is provided in the front of the evaporator 6. There is a suction grill. .

In the above configuration, when the heat pump type refrigeration cycle is operated and the sirocco fan 9 rotates, air outside the main body 1 is sucked into the main body 1 from the suction grill 18, heat is removed by the evaporator 6, and the air is drawn into the air outlet grill. 14 in the direction of arrow 19, and the air inside the drum 2 passes through the filter 12 and the vent 11 to the air guider 14.

It is blown out along. When the air inside the drum 2 is sucked, air outside the main body 1 is sucked in from the intake port 10 in the direction of the arrow 20, heated by the condenser 4, and introduced into the drum 2. The clothes in the drum 2 rotated by the drum 8 are evenly exposed and dried.

Therefore, by producing heated air to dry 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 increases and the drying time is increased. This has the effect of shortening the time and improving usability.

Effects of the Invention As is clear from the above embodiments, the present invention produces heated air using the condenser of a heat pump type refrigeration cycle and increases the amount of air introduced into the drum, thereby improving energy efficiency and drying. This has the effect of reducing the time required for the process and improving usability.
