The present invention relates to a washing machine, and in particular, by discharging high heat from the lower side of the laundry during the drying administration of the washing machine, exhausting the hot air to the outside and drying, thereby reducing the power consumption of the drying administration time and selectively washing the laundry. It is about a washing machine that can wash and boil.

In general, a washing machine having a drying function is fixed to the inside of the main body 100, as shown in FIG. 1, to clean the predetermined amount of washing water required for washing, and to support the safety lid 210 so as to open and close. A water tank 200 having an upper end installed in a closed state, a washing tank 300 provided in the inside of the water tank 200 to perform washing and dehydrating strokes, and provided on the bottom of the washing tank 300 alternately in the forward and reverse directions. A pulsator 400 which stirs the washing water while being rotated, a driving unit 500 which selectively rotates the washing tub 300 and the pulsator 400 according to a signal from the controller, and the inside of the main body 100. It is provided with a heating unit 600 provided on the rear upper side to heat-dry the laundry finished to the dehydration stroke with a high temperature.

The heating unit 600 of the configuration is a blowing duct 610 is configured to be sealed on the rear upper side inside the main body 100, and the disc member 220 sealed to the upper end of the water tank 200 in front of the blowing duct 610. Blowing fan 630 is installed in communication with the rear upper side of the blowing fan 630 is installed in the blowing duct 610 and is rotated by receiving the driving force of the driving motor (630a) installed in the upper upper side of the blowing duct 610. And a heating member 640 installed at an internal location of the blowing guide part 620 so as to be positioned in front of the blowing fan 630 and being heated by receiving power.

In the drawings, reference numeral 700 denotes an overflow pipe, and 800 denotes a drain valve. The washing machine having such a drying function receives a predetermined amount of washing water and detergent required for washing into the water tank 200 through a water inlet not shown, and the pulsator 400 and the washing tank 300 by a control program or user setting data. By selectively rotating the washing and rinsing, and the dehydration process is to be performed sequentially, and also the drainage of the wash water is drained through the drain by the operation of the drain valve (800).

When the dehydration stroke is completed, the pulsator rotates intermittently and turns the laundry over. At the same time, when the heating member 640 is heated, power is supplied to the driving motor 630a to drive the blower fan 630 to drive the heating member 640. The high heat generated is forced to circulate between the washing tank 400 and the water tank 200 and the washing tank 300.

Therefore, the high temperature forced circulation is introduced into the washing tank 300 through a plurality of through-holes (not shown) provided in the washing tank 300 to heat and dry the laundry, the water evaporated when the heat exchange in the water tank 300 is pulsed Between the eater 400 and the washing tub 300, and after passing through the bottom surface of the water tank 300 is discharged to the outside through the drain valve.

According to the operation principle, a washing machine having a drying function repeatedly performs water supply, washing, draining, rinsing, and dehydration drying operation according to a control program or user setting data.

However, the following problems occurred when performing the laundry administration of the laundry in the washing machine having a conventional drying function.

That is, in the drying operation of the laundry after dehydration, the pulsator 400 stirs the laundry in the wet state in the washing tank 300 by forward and reverse rotation, and at the same time, the blower fan 630 generates high heat emitted from the heating member 640. The high temperature and dry hot air introduced into the washing tank 300 in the process of forcibly flowing high temperature into the washing tank 300 and the water tank 200 and the washing tank 300 while drying the laundry by forced air blowing forms a heat exchange with the wet laundry and generates high temperature and humidity. The hot air is part of the hot air circulates in the closed water tank 200, and the remaining hot air flows back into the washing tank 300 through the drain valve and the overflow pipe, so that hot and hot air is repeatedly circulated in the hot and humid state. The drying efficiency is lowered and accordingly the drying administration time is long, the power consumption is increased.

In addition, a washing machine with a drying function does not have a separate boil function that boils steamed or oily laundry, so when washing a boiled laundry, the laundry must be boiled as a separate heating means. Another problem has arisen.

The present invention was devised in view of the above-mentioned conventional problems, and the washing machine can dry the laundry by adding hot dry hot air at the bottom of the washing tank during the drying administration, and improve the drying efficiency and reduce the power consumption due to the shortening of the drying administration time. The primary purpose of the present invention, and another object of the present invention is to provide a washing machine that can improve the washing efficiency by washing the steamed or oily laundry selectively boiled.

In order to achieve the above object, the present invention is installed on the bottom surface of the tank and the laundry irradiation, and heating means for selectively heating to a high temperature during washing and drying of the laundry, and is installed on the lower side of the tank in communication with the heating means It provides a washing machine configured to be driven only during the drying operation of the laundry and configured to blow high heat generated by the heating means into the lower portion of the washing tank.
