Abstract

A washing machine circulates washing water for washing and rinsing. A wash-and-dehydration basket for receiving the laundry is rotatably received in a water-receiving tub and is driven by a motor. A pump chamber is formed in an inner face of the water-receiving tub. The washing water between the wash-and-dehydration basket and the water-receiving tub is collected in the pump chamber by virtue of the rotation of the wash-and-dehydration basket and is pumped upwardly through the circulating path connected to the pump chamber. Since a small amount of water is employed for circulating and washing, precious water resources can be saved, and the washing performance can be further improved because highly concentrated washing water is employed for washing.

Description

591154 A7 _________B7_V. Description of the Invention (1) ‘Technical Field 坺 The present invention relates to a washing machine which circulates a washing bar water for washing and cleaning. BACKGROUND ART A conventional washing machine is shown in FIG. The water storage tank 17 encloses a washing and dewatering tank 18 provided in a freely rotatable manner, and is suspended from a washing machine casing 20 by a boom 19. The motor 21 rotates and drives the washing and dewatering tank 18 through the reduction mechanism 22, and the water supply valve 23 supplies water to the washing and dewatering tank 18. The water level detecting device 24 detects the water level in the water storage tank 17. The drain valve 25 discharges the washing water in the water storage tank 17. The control device 26 controls the motor 21, the water supply valve 23, the drain valve 25, and the like, and sequentially controls the steps of washing, washing, and dehydration. The operation of the above-mentioned washing machine will be described. When the laundry and the detergent are put into the washing and dewatering tank 18 and the operation is started, the control device 26 operates the water supply valve 23 to supply water to the washing and dewatering tank 18. Water level detecting device 24-Once a predetermined water level is detected, a signal is sent to the control device 26, and the control device 26 stops the operation of the water supply valve 23. Thereafter, the motor 21 is operated by the control device 26, and the washing and dewatering tank 18 is rotated. As shown in FIG. 11, the centrifugal force generated by the rotation of the washing and dewatering tank 18 is used to rotate the water surface of the washing water in the water storage tank 17 into a spider shape, that is, between the washing bar and the dewatering tank 18 and the water storage tank 17. The water surface rises and the central part drops. If the rotation speed of the washing and dewatering tank 18 is increased, the centrifugal force increases, and the water level between the outside of the washing and dewatering tank 18 and the water storage tank 17 gradually increases. Finally, the water level of the washing water exceeds the height of the upper end portion of the washing and dewatering tank 18, and water is scattered into the washing and dewatering tank 18 to circulate the washing water. In this way, the amount of water is stored in the water storage tank 17 (please read the notes on the back before filling this page)

By rotating the washing and dewatering tank 18 at a predetermined rotation speed, the washing water can be scattered and circulated. In addition, the circulation of the bar washing water promotes the dissolution of the knee wash. In this way, the washing water is dissolved and saturated before the point of the washing process, so that the detergent ingredients effectively act on the soiled parts of the laundry, thereby improving the cleaning performance of the laundry. Furthermore, with this structure, even in the circulation of the washing water, 'the mechanical force is not directly applied to the laundry' and the laundry is not damaged. In such a conventional washing machine, the centrifugal force generated by the rotation of the washing and dewatering tank 18 is used to form a mortar-shaped water surface of the purified water in the water storage tank π. Therefore, in order to disperse water from the water surface beyond the height of the upper end of the washing and dewatering tank 18, the minimum amount of washing water must also fill the space between the washing and dewatering tank 丨 8 and the water storage tank 17 plus the amount of water present in the washing and dewatering The total amount of water in the central portion of the water tank 丨 8 does not scatter water even when the rotation speed is increased when the water amount is below it. That is, in order to spread the water inwardly beyond the height of the upper end portion of the washing and dewatering tank 18, the water level of the washing water must be higher than a predetermined water level, which is disadvantageous for saving water resources. In addition, if a certain amount of detergent is added to a small amount of washing water, the washing water will have a high concentration, and although the washing power can be increased, the increase in washing power is also limited because it is disadvantageous for saving water resources. In addition, because this cycle of washing is only a direct cycle, the cotton thieves found in the washing water cannot be recovered. The washing machine of the present invention includes: a washing tank for accommodating laundry; a water storage tank for rotatably storing the washing tank in the interior; the size of the paper driven by the rotary drive washing tank is applicable to the Chinese National Standard (CNS) A4 specification (2 〖〇 > < 297mm） ^?
