Automatic dispensing device for detergent and rinse aid in the dishwasher

The present invention relates to an apparatus for automatically inserting detergent and rinse aid for a dishwasher, and more particularly, to a detergent and rinse aid for a dishwasher, in which the amount of detergent and rinse aid to be used in connection with the dishwasher can be constantly input to increase washing efficiency. and to a rinse aid automatic dispensing device.

BACKGROUND ART In general, a dishwasher is a device for washing dishes by spraying high-pressure washing water onto the dishes, and generally undergoes preliminary washing, main washing, rinsing, and drying steps.

In the preliminary washing step, washing water is sprayed without detergent to remove dishware residues, and in the main washing process, washing water is sprayed and detergent is injected by the detergent supply device at the same time to wash the dishes.

In a conventional dishwasher, when washing dishes, the dishwasher is operated by opening the door and inserting the detergent by hand using a dedicated spoon before the dishwasher operates, then closing the door and operating the dishwasher.

In the conventional dishwasher, the amount of detergent used once is not constant depending on the user, and when the user wants to add detergent while the dishwasher is in operation, be sure to stop the operation of the dishwasher and then open the door to open the detergent. It was troublesome to add and operate again.

In the conventional dishwasher, only the detergent has to be manually inserted in the dishwasher, which automatically washes the dishes, so whenever the user uses the dishwasher, the user has to put the detergent on his hand, and after use, the remaining detergent must be stored safely in a designated place. There was a drawback with the inconvenience of having to store it.

Invented from the above point of view, there may be mentioned "automatic detergent input device for dishwasher" (hereinafter referred to as prior art) of Public Notice Utility Model No. 20-1989-0004037.

In the prior art, as shown in FIG. 11, the connection port 6, 6 of the lid 5 to the fixture 4, 4' of the main body 3 in which the detergent storage unit 1 and the detergent outlet 2 are formed. ') is coupled and fixed by fixing pins (7) (7'), and in the center of the body (3), the shaft of the DC motor (9) mounted on the motor holder (8) fixed to one side is inserted through and fixed. The rotary roller 11 on which the detergent container part 10 of the size is molded is installed.

In the prior art, a cam 13 having a locking groove 12 formed on the other side of the rotary roller 11 is inserted into the penetrating end portion and fixed by a fixing washer 14, and the main body 3 is lowered by the cam 13. The link 18 is inserted into the guide cap 23 attached to the surface, but on the lower surface of the link 18, the fixing pin 7 " ), the guide pin 17 for operating the operating plate 16 coupled to the fitting is fixed.

In addition, in the prior art, a spring 20 installed on an auxiliary plate 19 obliquely attached to the surface of the body 3 is in close contact with the lower portion of the operation plate 16 , and a support plate that controls the operation of the operation plate 16 is attached to the upper portion of the operation plate 16 . (21) is attached to the surface of the main body (3) obliquely, and it is used by using the fixing piece 22 in a part of a conventional dishwasher.

However, in the prior art, although the lid 5 is opened and the detergent is filled, there was a cumbersome point in use, such as a portion of the detergent flowing down to the edge of the detergent storage unit 1 in the process of filling the detergent.
