The present invention relates to a washing machine, and more particularly, to a washing machine which can prevent the liquid agent from sticking in the liquid outlet pipe and improve the flow of the liquid agent supplied to the washing tank.

4 is a perspective view of a washing machine having a conventional rinsing agent container, and FIG. 5 is an enlarged cross-sectional view of the rinsing agent area of FIG. 4. As shown in these figures, a conventional washing machine has a rectangular cylindrical casing 101 forming 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 to be bonded. The casing 101 is provided with a cylindrical outer tub provided to accommodate the wash water, and a washing tub 107 installed in the outer tub to be rotatable and driven with an accommodating part accommodating the laundry.

An opening 109 is formed in the central area of the top cover 105 for taking out and receiving laundry, and a door 111 that can be folded to open and close the opening 109 is installed at the rear edge of the opening 109. It is. An operation unit 113 provided with a plurality of operation switches is provided in the front region of the top cover 105, and a pair of water supply pipes are provided in the rear region of the top cover 105 to supply cold water and hot water into the washing tank 107. 115). The water supply pipe is provided with a pair to supply cold water and hot water, and the lower side of the water supply pipe 115 is provided with a detergent container accommodating portion 117 having one side opened toward the washing tank 107 side.

In this case, a water supply opening (not shown) is formed above the detergent container receiving portion 117 so as to communicate with the water supply pipe 115, and the detergent container receiving portion 117 is capable of sliding out along the opened side. The container 119 is provided. The detergent container 119 has a detergent accommodating part 121 in which powder detergent is accommodated, and the filter member 123 is disposed on the upper part of the detergent accommodating part 121 to block the detergent mass from flowing into the washing tank 107. Is rotatably coupled.

On the other hand, in the rear region of the top cover 105, a rinsing agent container 130 for automatically introducing the rinsing agent into the washing tank 107 is provided. The rinsing agent container 130, as shown in Figure 5, the inlet opening 131 for receiving the rinsing agent in the shape of a funnel and injecting the rinsing agent at the top, and the outlet opening downward for the outflow of the rinsing agent at the bottom 133 is formed.

One end of the outlet 133 is connected to the outlet 133, and the other end of the rinse agent outflow pipe 137 is opened to the washing tank 107. A rinsing agent valve 139 is provided at one region in the longitudinal direction of the rinsing agent discharge pipe 137 to control the outflow of the rinsing agent, and an opening opening (131) is provided at the upper input opening 131 of the rinsing agent container 130. The container cover 135 for opening and closing the 131 is provided.

By such a configuration, the user withdraws the detergent container 119 accommodated in the detergent container accommodating part 117 according to the amount of laundry, and puts an appropriate amount of powder detergent into the detergent accommodating part 121. Thereafter, when the user sets the washing course, the water supply valve (not shown) is opened to wash the water into the detergent accommodating part 121, and the injected washing water dissolves the powder detergent in the detergent accommodating part 121 in a liquid state. It is supplied to the washing tank 107. When the input of the detergent and the washing water is completed, the washing administration proceeds according to the washing course selected by the user, and when the washing is completed, a plurality of rinsing strokes which sequentially proceed with water supply, rinsing, and draining are performed.

On the other hand, if it is determined that the last rinsing stroke in the course of a plurality of rinsing stroke, the control unit (not shown) to supply the washing water by opening the water supply valve, and also, by opening the rinse agent valve 139, the rinsing agent container 130 The rinsing agent which is a fiber softener accommodated in is supplied into the washing tank 107.

However, in such a conventional washing machine, since the liquid agent such as the rinsing agent flowing out into the washing tank is relatively viscous, it may stick to the rinsing agent outflow pipe that is the liquid outflow pipe when supplying the liquid agent such as the rinsing agent. Since the flow of the liquid agent such as the rinse agent is lowered, there is a problem in that the liquid agent such as the rinse agent is not smoothly made.

Accordingly, an object of the present invention is to provide a washing machine which can prevent a relatively viscous liquid from sticking to the liquid outflow pipe and improve the flow of the liquid supplied into the washing tank.
