[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a washing machine, etc., in which detergent supplied from a detergent supply section is put into a tank of the washing machine, etc. This invention relates to a detergent supply device.

(Prior Art) As a detergent supply device for this type of washing machine, a water supply passage is provided below the 1"F supply port of the detergent supply section, and a water supply passage is provided on this water supply passage from the supply port. The detergent is allowed to fall and is flushed into the tank by water supplied to the water supply passage.

(Problem to be Solved by the Invention) However, in the conventional +M configuration described in Section 2, the water supply passage opens facing the inside of the tank, so during washing operations etc., the water in the tank flows into the detergent 1 supply section. (jl) There was a problem with the detergent splashing on the inlet, solidifying the detergent at the inlet, and causing malfunction.Also, during spin-driving, etc., the vibration caused detergent 1.
There was also the problem that the detergent could fall from the 1 co-supply section of the co-supply department, and in this case, the detergent could land on the laundry in +1.!i.

In order to solve this problem, a detergent receiving member is provided below the supply port of the detergent supply section, and this detergent receiving member is used to receive the detergent that has fallen from the double-layer supply port. +L receiver 1 [can be rotated between the second position and the inclined position that guides the detergent supplied from the supply port to the tank side] I7.9
A method is being considered to make this possible. In this configuration, detergent official operations 11. The detergent receiving member 11 is rotated to an inclined position, and the detergent supplied to the detergent receiving member 11 is fed to the detergent receiving member 11 by water supplied from the water supply means.
I try to let it flow into the room.

When detergent is not added, the detergent receiving member is rotated to the receiving position to prevent water from inside the tank from splashing onto the supply opening of the detergent supply unit, and to prevent vibrations. Even if the detergent falls from the fj (feeding port), it is designed to catch it (11).

On the other hand, in the second configuration, after the end of the detergent injection operation, the supply of water to the detergent receiving member in the inclined position is stopped, and at the same time, the detergent receiving member is moved to the receiving position. Since the detergent receiving member is rotated until the detergent receiving member is in the stop position, two sides of the detergent receiving member are covered with water. For this reason, if a detergent falls from the supply port onto the detergent receiving member where such water has spilled, the detergent or the detergent receiving member H When it becomes solidified at 'double', point m occurs.

Therefore, the first object of the present invention is to prevent detergent from clumping on the surface of the detergent receiving member provided on the side of the detergent supplying section. Provide the device 1"1

After washing, the detergent receiving member 30 is kept tilted for about 5 seconds. Flowing down,
Water can be drained from the detergent receiving portion side 30. Therefore, the detergent receiver 11 member 30 filled with water is rotated to the receiving position to receive the detergent falling from the supply port 15a of the detergent supply part 15. Since there is a -C, you can make sure that the detergent or tL agent receptacle 1 [memory member 30] hardens in the second place.

[Effects of the Invention] As is clear from the above description, the present invention stops the supply of water onto the detergent receiving member at the inclined position when the detergent injection operation ends, and then restarts the detergent after a predetermined period of time has elapsed. Since the four receiving parts are rotated to the receiving position, the water from the second member of the detergent receiving part 11 can be sufficiently ejected after water is supplied. This has the excellent effect of preventing detergent from solidifying even if it falls on the upper surface of the moon.
