Conventional technology When adding detergent to a conventional washing machine, the detergent is put directly into the washing tub, or, for example, in a washing machine that has a circulation path using a pump-up of a rotary blade, the detergent is circulated through the detergent inlet near the lint filter. There are some structures that can be deployed along the route.

Furthermore, as shown in Japanese Utility Model Application Publication No. 59-181670, there is a washing machine in which a powder detergent dissolving device for dissolving powder detergent is provided separately from the washing machine, and the dissolved detergent water is supplied to the washing tub.

Problems that the invention aims to solve In the conventional configuration, a detergent inlet is provided in the middle of the path to capture lint and collect dust, but this detergent inlet is located on the inner wall of the washing tub and dehydration tank. Or, since it is located above the washing tub/spinner tub, it is difficult to add detergent, and the washing tub/spinner tub rotates with each operation, making it difficult to determine the position of the detergent inlet, and the user has to manually insert the detergent into the washing tub/spinner tub. This was a problem because it required rotating and moving.

In addition, in the method disclosed in Japanese Utility Model Application Publication No. 59-181670, the detergent dissolving device is provided separately from the washing machine, which causes the problem that the detergent dissolving device protrudes from the main body of the washing machine and becomes an obstacle when removing clothes. had.

In view of the above-mentioned problems, the present invention provides a detergent loading device that facilitates the removal of clothes from the washing machine.
To make it easy to take out a detergent input case and to easily clean the detergent input case.

Means for Solving the Problems In order to achieve the above object, the present invention comprises an upper frame body that constitutes the upper part of the main body of the device and has a clothes input port, and an upper frame body that is provided at the rear of the clothes input port and that extends horizontally. A water filler main body that stores a detergent dispenser case that can be freely pulled out, and a water filler spout that is provided above the detergent dispenser case and that jets water from a plurality of holes, and near an opening of the water filler main body into which the detergent dispenser case is inserted. L-shaped stoppers are formed above both inner walls of the water inlet main body, and protruding ribs corresponding to the stoppers are formed on both rear walls of the detergent dispenser case, and at the same time, a corner portion of the lower rear surface of the detergent dispenser case is formed. When the detergent dispenser case is completely pulled out, the protruding rib comes into contact with the stopper and becomes in a restrained state, and when the detergent dispenser case is removed, the detergent dispenser case is pulled out to the restrained state and the detergent dispenser case is stopped. By pulling the front part upward, the detergent injection case rotates around the stopper, and the contact between the stopper and the protruding rib is released.

Function As mentioned above, when adding detergent to the detergent case, when the detergent case is horizontally moved and pulled toward you, the detergent case becomes ready for detergent injection, and after the detergent is added, pulling and pushing it completes the storage. Furthermore, when foreign matter or the like adheres to the detergent injection case and cleaning becomes necessary, it can be easily removed by pulling it up toward you. Normally, when adding detergent, the detergent injection case is moved only horizontally, and when cleaning etc. is necessary, it is pulled up towards you.
