Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a structure for supplying water to a dispenser that automatically dispenses detergent into a fully automatic washing machine.

[Technical background of the invention and its problems]

As shown in FIG. 1, in a conventional automatic detergent dispenser installed in communication with one side of a fully automatic washing machine, a detergent container 2 is installed in a main body 1 so as to be able to rise and fall, and the detergent container 2 is filled with detergent. The detergent container 2 is housed, and its tip is supported by a bar 4 that moves forward and backward by a solenoid 3. When detergent is added, the bar 4 is moved back by the excitation of the solenoid 3, and the detergent container 2 is supported by the bar 4.
rotates downward to throw the stored detergent into the main body 1. At the same time, the solenoid valve 6 of the water supply pipe 5 opens and water is sprayed from the water supply port 7 of the water supply pipe 5, which opens from the middle of the main body 1 into the detergent container 2 in the inverted position, washing away the detergent. It is introduced into the washing machine through the outlet 8. However, the bottom of the detergent container 2 in a downwardly rotated state is at a lower position than the water level of the main body 1 when it is full, and therefore the water inlet 7 of the water supply pipe 5 that sprays water onto it is also compared to the main body 1. Since the opening is close to the target water surface, detergent water may flow back from the main body 1 into the water supply pipe 7 when the main body 1 is full of water. Furthermore, the law stipulates that there must be a distance of 200 mm or more between the height of the water level and the water inlet. moreover,
Since the detergent is sprayed into the detergent container 2 from the narrow water supply port 7, it is difficult to wash away the entire surface of the container 2, causing problems such as detergent remaining and water scattering around when the water pressure is high.

[Purpose of invention]

In view of the above-mentioned problems, the present invention provides a water inlet on the main body of the detergent dosing device at least 200 mm higher than the water level when the water is full, and allows the detergent container installed in the main body to be tipped over from this water inlet. A water sprinkling guide tube with a vent opening at the top end is installed to disperse the water supply into the container at the specified location, and the water supply port is placed at a high place to prevent backflow of detergent. It is designed so that the entire inside of the container can be washed away by spreading it out.

[Summary of the idea]

The present invention consists of a detergent dispenser body that is connected to one side of a fully automatic washing machine, a detergent container that is freely tiltable on this body, and a water level that is at least 200 mm higher than the water level when the body is full. The detergent container is made up of a water supply port that is provided at a location and communicates with a water supply pipe, and a water sprinkling guide tube that is connected to the water supply port and has a vent opening at the upper end that spreads the water supply and sprays water toward the inside of the detergent container in an inverted position. This prevents backflow from inside the main body to the water supply pipe and thoroughly flushes the inside of the detergent container.

is open.

20 is a detergent container which is connected to the detergent inlet 1 of the main body 14;
The inner end is supported by a bar 21 hanging from the upper end of the main body 14 so as not to rotate downward, and the bar 21 is a solenoid provided on the main body 14. 22 so that it can move forward and backward in the vertical direction. Furthermore, a stopper 23 is provided at the lower part of the main body 14 to restrict the downward rotation of the detergent container 20 and hold it at a constant angle.

Reference numeral 24 denotes a water sprinkling guide cylinder, which has front and rear plates 25 and 26 extending in the left-right direction toward the detergent container 20, which are brought close to the front and rear of the water supply pipe 17 protruding from the upper part of the interior of the main body 14.
and both side plates 27, 27, and the lower end is formed with a water spout 28 that is elongated in the left-right direction and narrowly opened in the vertical direction toward the detergent container 20 in the inverted position that has been rotated downward, and the main body 14 is formed on one side of the upper end. A vent hole 29 that is long in the left-right direction is opened toward the input port 18. Further, a water sprinkling pipe 30 is connected to the lower end of the water supply pipe 17 opened in the water sprinkling guide cylinder 24, and is connected to the opening of the water supply pipe 17 in a T-shape and has a length parallel to the water spout 28. The rear plate 26 of the water sprinkling guide tube 24 near the lower end of the peripheral surface of the water sprinkling pipe 30
A large number of water supply holes 31, which serve as water supply ports, are opened along the axial direction at positions inclined by an angle θ toward .

Next, the operation of the above embodiment will be explained.

When a detergent input signal is issued in the middle of the washing process, the solenoid 22 is energized, the bar 21 is pulled up, the detergent container 20 is rotated downward, and is supported by the stopper 23 to be in the tilted state shown by the chain line in FIG. is thrown into the main body 14. At the same time, the solenoid valve 16 of the water supply pipe 17 is energized and water supply starts, and the water supply pipe 1
The water supplied to the water sprinkling pipe 30 from 7 spreads in the left and right direction toward the detergent container 20 in the water sprinkling pipe 30, and flows backward through a large number of water supply holes 31 inclined at an angle θ to the rear of the water sprinkling guide pipe 24. The water sprays toward the face plate 26, flows down along the rear plate 26, and reaches the water spout 2 at the lower end.
