This is a space 25a for introducing a detergent for a washing stroke from the left side of FIG. 2, a space 25b for injecting a softening agent for a rinsing stroke, and a space 25c for injecting a functional detergent according to a user's needs.

The watering device 30 includes a lower cover 31 and an upper cover 32. The lower cover 31 is formed with a plurality of water injection holes 33 to inject water into each space of the detergent container 22. The upper cover 32 is coupled to the upper portion of the lower cover 31 to form a water supply passage together with the lower cover 31. As shown in FIG. 3, the watering device 30 has a plurality of space compartment ribs 34a, 34b, and 34c, and the first space 35a, the second space 35b, and the first space from the left side of FIG. It is divided into three spaces 35c. In addition, a plurality of flow path partition ribs 37a, which form flow paths 36a, 36b, 36c, and 36d for selectively supplying water to the spaces 35a, 35b, and 35c which are divided into each other in the watering device 30, 37b, 37c, and 37d are provided. The first, second, and third water supply ports 41, 42, 43 for selectively supplying water to each of the flow paths 36a, 36b, 36c, and 36d are provided behind the watering device 30. And the circumferential side of the lower cover 32 is provided with a fusion rib 38 for limiting the inner space of the sprinkler 30 and the fusion coupling of the upper cover 32 and the lower cover 31. The fusion rib 38, the space compartment ribs 34a, 34b, 34c, and the flow path ribs 37a, 37b, 37c, 37d protrude upward from the upper surface of the lower cover 31 and are fused to the lower surface of the upper cover 32. Combined.

This watering device 30 is a detergent container (by allowing the water supplied from at least one of each of the water supply ports 41, 42, 43 to selectively flow into the first to third spaces (35a, 35b, 35c) therein) Each of the spaces 25a, 25b and 25c in 22 allows for selective water supply. As such, when water is supplied, water is selectively supplied to the water supply ports 41, 42, and 43.

The rear side of the watering device 30 is provided with a silver solution supply unit 50 is integrated with the watering device (30). The water to be supplied is made of silver solution to be supplied to the water tank (11). As shown in FIG. 4, the silver solution supply device 50 includes a silver solution chamber 51 and a silver solution chamber 51 formed as a compartment by a fusion coupling between the upper cover 32 and the lower cover 31. It includes a pair of silver plates 52 and 53 spaced apart from each other and installed to be flooded. The pair of silver plates 52 and 53 are installed to enter the silver solution chamber 51 in a state in which the pair of silver plates 52 and 53 are coupled to the cover portion 54 installed on the upper cover 32 side. The upper portion of the silver solution chamber 51 is sealed by the coupling of the cover portion 54. As shown in Figs. 2 and 3, the silver solution chamber 51 is surrounded by a rhombus fusion rib 39 to be partitioned into a separate space.

One side of the silver solution chamber 51 is provided with the above-described first water supply port 41 so that water can be introduced into the inside, and the other side of the silver solution chamber 51 has an outlet 55 through which the water can be discharged. Is prepared. The discharge port 55 faces the flow path 36b associated with the first space 35a to supply water to the first space 35a of the watering device 30. This is to allow the water flowing through the first water supply port 41 to become a silver solution in the process of passing through the silver solution chamber 51. That is, by applying a current having a predetermined voltage to the pair of silver plates 52, 53, the silver ions are electrolyzed from the silver plates 52, 53 so that the silver ions are mixed with the water supplied. The silver solution prepared in this way is put into the water tank 11 to sterilize the laundry.

On the other hand, the fusion rib 38 provided along the circumferential side of the watering device 30 is composed of a layer as shown in FIG. Moreover, the fusion rib 39 surrounding the silver solution chamber 51 is also comprised by a layer. This means that the upper cover 32 and the lower cover 31 are coupled to each other by the fusion ribs 38 and 39 of the layered layer so that the coupling around the sprinkling device 30 is as strong as that. The water is not leaked toward the circumference of the device 30. In the example of FIG. 3, two layers of fusion ribs 38 and 39 are provided around the watering device 30 and around the silver solution chamber 51, but the fusion ribs may be three or more layers.

The silver solution chamber 51 is formed long in the horizontal direction (left and right width directions of the sprinkler) as shown in FIG. That is, it is formed long in the left and right directions of FIG. This minimizes the silver solution supply device 50 protruding toward the back of the sprinkler 30 so that the front and rear lengths of the upper and lower covers 32 and 31 can be as short as possible. In this way, shortening the front and rear lengths of the upper cover 32 and the lower cover 32 can reduce the imbalance of the fusion surface, thereby facilitating fusion and reducing the fusion defect.

As described above in detail, the detergent supply device of the washing machine according to the present invention is because the fusion ribs provided on the circumferential side of the sprinkler for the coupling of the lower cover and the upper cover of the sprinkler is composed of a layer of fusion of the sprinkler around the sprinkler It can increase the effect of minimizing the leakage of water from the sprinkler.

In addition, the present invention is because the fusion ribs of the layer is also provided around the silver solution chamber provided on one side of the watering device has the effect of minimizing the phenomenon that the wash water from the silver solution chamber side.

In addition, the present invention can minimize the length before and after the upper cover and the lower cover of the watering device because the silver solution chamber is formed long in the left and right width direction of the watering device. Therefore, by minimizing the imbalance between the upper cover and the lower cover fusion surface can be easily fusion and can reduce the fusion defect.
