The powder dispenser 130 is provided with a powder introduction hole 131 into which the powder detergent is introduced and a detergent guide plate 132 for storing the powder detergent dropped through the powder injection hole 131. The detergent guide plate 132 has an inclination and is connected to the water supply pipe 111 so that the wash water flows in.

Therefore, when the washing administration is carried out, the washing water flowing through the water supply pipe 111 is moved through the detergent guide plate 132 and mixed with the powder detergent and guided to the tub 60. Reference numeral 133 is an inlet pipe one end is in communication with the detergent guide plate 132 inside the detergent housing 110, the other end is in communication with the tub 60 to guide the powder detergent or wash water to the tub (60).

One end of the housing cover 140 is hinged to the detergent housing 110 to open and close the upper portion of the detergent housing 110. The housing cover 140 prevents foreign substances from flowing into the liquid reservoir 120 and the powder introducer 130.

Dual detergent input device according to an embodiment of the present invention is further provided with a liquid lid portion 150. The liquid cover part 150 is provided with a mounting part 151 and a cover part 152, and closes the opening hole 115 to prevent the liquid detergent from solidifying due to contact with air.

The mounting portion 151 is seated on the mounting plate 112 formed in the detergent housing 110 and the liquid injection hole 153 is formed. The seating plate 112 is formed on the wall surface of the detergent housing 110 in which the opening hole 115 is formed, and protrudes toward the center of the opening hole 115. In one embodiment, the seating plate 112 has a circular shape.

One end of the cover part 152 is rotatably coupled to the mounting part 151, and the other end is detachably attached to the mounting part 151 to open and close the liquid injection hole 153.

In one embodiment, the cover portion 152 is rotated by one end coupled to the hinge 154 to the mounting portion 151. In addition, the cover part 152 is provided with a hook 156 at the other end, and the mounting portion 151 is provided with a locking groove 159 to hook the hook 156.

The mounting portion 151 is provided with a locking protrusion 157 that is inserted into the guide groove 113 of the detergent housing 110 and locked. The guide groove 113 is formed on the wall surface of the detergent housing 110 in which the opening hole 115 is formed. In one embodiment, the guide groove 113 is in communication with the vertical groove portion 113a for guiding the locking projections 157 in the vertical direction and the lower end of the vertical groove portion 113a and for guiding the locking projections 157 in the horizontal direction. The horizontal groove 113b is provided. Therefore, the locking projection 157 is guided to the vertical groove portion 113a and then rotated to guide the horizontal groove portion 113b to be locked.

The mounting part 151 is provided with a guide plate 155. The guide plate 155 is connected at the edge portion of the mounting portion 151 and guides the liquid detergent to the liquid injection hole 153. In order to smoothly move the high liquid detergent, the guide plate 155 is formed with a curvature. In one embodiment, the guide plate 155 has a funnel shape.

Referring to the operation of the dual detergent input device of the automatic washing machine having the structure as described above are as follows.

When using the powder detergent, the user rotates the housing cover 140 to expose the powder injection hole 131, and then put the powder detergent into the powder injection hole 131. Then, the powder detergent is temporarily stored in the detergent guide plate 132.

In the above state, the wash water supplied through the water supply pipe 111 is introduced into the detergent guide plate 132, mixed with the powder detergent, and then moved to the tub 60 through the inlet pipe 133.

When using the liquid detergent, the wash water supplied through the water supply pipe 111 is guided to the tub 60 through the inlet pipe 133, the liquid detergent stored in the liquid reservoir 120 by the pump 122 The tub 60 is guided by the set amount.

When the liquid reservoir 120 lacks the liquid detergent, the user rotates the housing cover 140 to open the upper portion of the detergent housing 110, and then the hook 156 of the cover portion 152 is the locking groove 159 In order to be separated from the liquid injection hole 153 is exposed.

In the above state, when the liquid detergent is introduced, the liquid detergent is guided to the liquid introduction hole 153 through the guide plate 155 and stored in the liquid reservoir 120.

On the other hand, the user can detach and attach the liquid cover part 150 to wash the solidified liquid detergent. That is, when the liquid cover part 150 is rotated to separate the liquid cover part 150, the locking protrusion 157 is positioned in the vertical groove part 113a. When the liquid cover part 150 is moved upward in the above state, the liquid cover part 150 is separated from the detergent housing 110 and can be separately washed. The process of coupling the liquid cover part 150 is performed in the reverse order of the above-described process.

In addition, the user may also wash inside the liquid reservoir 120. That is, when there is almost no liquid detergent remaining in the liquid reservoir 120 and foreign matter or solidified liquid detergent is attached to the inside of the liquid reservoir 120, the user pulls the handle 162 of the opening and closing unit 160 to wash it. By separating from the tube 123, the washing tube 123 is opened. In the above state, when the inside of the liquid reservoir 120 is washed using the washing water, the washing water is discharged through the washing tube 123, and the discharged washing water is guided to the tub 60 through the moving tube 124.

When the cleaning of the liquid reservoir 120 is completed, the cleaning tube 123 is closed by being press-fitted into the insertion unit 163 and the cleaning tube 123 of the opening and closing unit 160. Thus, even if the liquid detergent is stored in the liquid reservoir 120, the liquid detergent is not discharged through the washing tube 123.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
