Definitions
- the present invention relates to a drum type washing and drying machine executing washing, rinsing, dewatering and drying processes in a rotary drum.
- FIG. 11 there is illustrated a drum type washing and drying machine. The configuration thereof will now be described hereinafter.
- housing 1 accommodates therein water tub 4 supported by a plurality of suspensions 2 and dampers 3 .
- the opening of water tub 4 is opened and closed by door 5 .
- Rotary drum 6 having a generally slanted rotation axis is rotatably mounted in water tub 4 , and a number of water passing holes 7 and baffles (or vanes) 8 are provided in rotary drum 6 .
- Water supply valve for washing operation water supply means, referred to as washer water valve hereinafter
- water supply valve for drying operation referred to as dryer water valve hereinafter
- Water outlet 11 provided at water tub 4 communicates with drain pump (drain means) 12 via drain pipe 13 .
- Blower 15 functioning to blow air into water tub 4 through air injection opening 14 , heater 16 in communication with blower 15 , and heat exchanger 17 in communication with water tub 4 and blower 15 constitute a drying air circulation path.
- Water supply hose 18 supplies water from dryer water valve 10 to heat exchanger 17 .
- washer water valve 9 is opened to fill fresh water in water tub 4 up to a predetermined water level.
- rotary drum 6 is driven to rotate at about, e.g., 50 r/min, and the loaded laundry articles are subject to repeated lift-up and drop motions by baffles 8 and are washed by washing fluid with the aid of impact of dropping on a surface of the water.
- the washing fluid is drained through drain pipe 13 by driving drain pump 12 .
- the laundry articles are dewatered by rotating rotary drum 6 at a high rotation speed of about 1000 r/min.
- the dewatering operation is followed by the drying operation.
- rotary drum 6 is driven to rotate to enable the laundry articles therein to move up and down as in the washing operation and, at the same time, hot air heated by heater 16 is supplied to the laundry articles in rotary drum 6 by blower 15 through air injection opening 14 , so that moisture in the laundry article is heated and evaporated therefrom.
- the hot air containing therein water vapor is directed to heat exchanger 17 ; and then the hot air is cooled down and dehumidified by the heat exchange process induced by way of being mixed with the cooling water provided from dryer water valve 10 to heat exchanger 17 .
- the drying operation of laundry articles is executed, as the dehumidified air is re-heated by heater 16 and re-directed into rotary drum 6 , which constitutes a series of drying cycles.
- heat exchange in such heat exchanger 17 is carried out by uniformly dispersing the cooling water within the space of heat exchanger 17 with the aid of a wind pressure of the circulating air.
- the wind pressure inside heat exchanger 17 having a narrow cross sectional shape will be increased excessively. Consequently, the balance between the wind pressure and the aerially scattered cooling water is disturbed, and thus the cooling water is driven to fly upwards to reach heater 16 so that the drying efficiency is degraded considerably.
- heat exchanger 17 may be clogged, leading to a failure of the drying operation.
- an object of the present invention to provide a drum type (or front-loading) washing and drying machine capable of performing a dehumidification process by way of utilizing a large inner space of a water tub, without building a separate heat exchanger at the outside thereof, to thereby improve the dehumidification efficiency and at the same time prevent the occurrence of the prior art problems of the flying-back of cooling water and the clogging-up of the heat exchanger owing to the accumulation of lint, etc.
- a drum type washing and drying machine including: a rotary drum; a water tub including therein the rotary drum; a water supply member for supplying cooling water into the water tub; a heater for heating air; a blower for blowing the heated air into the water tub to evaporate moisture from laundry articles in the water tub; and a dehumidification means for cooling and dehumidifying air containing the evaporated moisture by the cooling water, wherein the dehumidification means is provided in a space between the water tub and the rotary drum.
