Description

washer

The present invention relates to a washing machine, and more particularly, to a washing machine capable of automatically supplying a rinsing agent into a washing tank.

5 is a perspective view of a washing machine having a conventional detergent container, and FIG. 6 is an enlarged perspective view of the detergent container of FIG. 5. As shown in these figures, a conventional washing machine includes a casing 101 having a substantially rectangular cylindrical shape that forms an outer appearance, a top cover 103 coupled to an upper portion of the casing 101, and a lower portion of the casing 101. It has a base plate 105 coupled to.

Inside the casing 101, a cylindrical outer tub provided to accommodate the wash water and a washing tub 107 provided inside the outer tub to perform washing, rinsing, and dehydration are rotatably installed.

An opening 109 is formed in the central area of the top cover 103 to accommodate and withdraw laundry, and a rear door 111 is provided at the rear edge of the opening 109 so that the opening 109 can be opened and closed. have. An operation unit 113 having a plurality of operation switches for operating a washing machine is attached to the front region of the top cover 103, and the rear region of the top cover 103 supplies washing water from an external water supply device. Water supply line is connected. The lower side of the water supply pipe is provided with the detergent container accommodating part 115 which opened one side surface toward the washing tank 107 side.

At this time, an upper portion of the detergent container accommodating part 115 is formed with a water inlet (not shown) opened to communicate with the water supply pipe, and the detergent container accommodating part 115 is capable of sliding out along the open side of the detergent container 117. ) Is provided. The detergent container 117 is divided into a detergent accommodating part 119 for accommodating powder detergent and a rinsing accommodating part 121 for accommodating a rinsing agent. The filter member 129 is rotatably coupled to the upper portion of the detergent accommodating part 119 to block the detergent mass from flowing into the washing tank 107.

Meanwhile, the rinsing agent accommodating part 121 includes a discharge path 123 having a discharge port 125 for discharging the rinsing agent supplied from the outside to the outside, and a discharge path cover 127 provided to surround the discharge path 123. Have In addition, one region of the casing 101 is provided with a rinsing agent supply water supply valve for supplying washing water to the rinsing agent accommodating part 121 at the time of rinsing agent introduction.

According to this configuration, when washing the laundry, the detergent container 117 contained in the detergent container accommodating portion 115 is taken out according to the amount of the laundry, and the amount of washing is carried out in the detergent accommodating portion 119 and the rinsing agent accommodating portion 121. Add an appropriate amount of powder detergent and rinse agent. After the detergent and the rinsing agent are added, washing is started, and the powder detergent contained in the detergent accommodating unit 119 is dissolved in a liquid state by the washing water supplied from the water supply pipe, and is then introduced into the washing tank 107.

On the other hand, when the end of the rinsing stroke after the end of the washing stroke, the water supply valve for rinsing agent input is opened and the washing water is supplied to the rinsing water receiving unit 121, thereby rinsing housed in the rinsing water receiving unit 121 It is introduced into the washing tank 107 with the wash water supplied by me.

However, in such a conventional washing machine, in order to supply the rinsing agent to the washing tank before the last rinsing administration, the user must directly put the rinsing agent into the rinsing agent container before starting the washing, which is not only troublesome, but also the rinsing agent itself. Forgetting that happens. In addition, the rinsing agent accommodating part provided in the detergent container has a problem that the size of the rinsing agent accommodating part is small and is located on the rear side of the washing tank, so that the rinsing agent is not easily added.

Accordingly, an object of the present invention is to provide a washing machine capable of automatically supplying a rinsing agent into a washing tank.
