Problems solved by technology

Therefore, in areas where the temperature is relatively low, the temperature of the water supplied to the outer tank is low, and there is a danger that the laundry cannot be washed with sufficient cleaning power.
[0004] In addition, in recent years, in order to improve the cleaning power, detergents mixed with enzymes have been popularized. However, in this enzyme, the higher the temperature, the more active it is, and the higher the cleaning power. When using such detergents for washing, If the temperature of the water supplied to the outer tank is low, the degree of improvement of the detergency of the enzyme may not be desired.

Embodiment Construction

[0030] Embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0031] figure 1 It is a longitudinal cross-sectional view of front-loading-type washing machine 1 according to an embodiment of the present invention, and shows a cross-sectional view taken along a vertical plane along the left-right direction as viewed from the front. in addition, figure 2 This is a longitudinal cross-sectional view of the front-loading washing machine 1 , which shows a cross-section taken along a vertical plane along the front-rear direction as viewed from the right side.

[0032] refer to figure 1 and figure 2 , the outer shape of the drum-type washing machine 1 is determined by a substantially rectangular parallelepiped shell 2 . On the top surface of the casing 2, an opening 4 is formed for taking in and out laundry which can be opened and closed by the outer cover 2A. Inside the case 2, an outer groove 7 is formed in such...

Abstract

This inventon provides a drum type washing machine for improving washing power with less electric power. After a washing process (step S2) is ended and water inside an outer tub is discharged (step S3) and before a spin-drying process (step S5) is started, by rotating a drum while supplying warm air into the outer tub by a drying unit, a warm air washing process is executed (step S4). In the warm air washing process, water contained in laundry after water discharge is warmed by the warm air supplied from the drying unit into the outer tub. Then, since the laundry containing the warmed water is rubbed with other laundry and the inner surface of the drum and hit to the inner surface of the drum accompanying the rotation of the drum, washing by the warm water is achieved. A relatively small amount of the water contained in the laundry after draining is warmed in a short time and washing (warm water washing) is performed.

Description

technical field [0001] The present invention relates to a drum type washing machine which receives laundry in a drum for washing. Background technique [0002] Conventionally, there has been known a drum-type washing machine in which laundry is received and washed in a cylindrical drum that rotates about a rotating shaft that extends substantially in a horizontal direction. The drum is installed inside the outer tank. When the front-loading washing machine starts to operate, water (tap water) is supplied to the inside of the outer tank from a water supply device (faucet, etc.) other than the washing machine, and a certain amount of water is stored in the outer tank. . Then, the drum is rotated, thereby repeating the following action, that is, the laundry in the drum is lifted up by the baffle plate protruding from the inner surface of the drum, and falls naturally toward the water surface from a certain height (tumbling), Thus, washing (pat washing) of the laundry is perfo...
