Description

Dishwasher dispenser for dishwasher {Dishwasher dispenser}

The present invention relates to a dispenser for facilitating the supply of detergent for a washing appliance, especially a dishwasher, and was developed in relation to a dispenser that opens and closes the detergent chamber cover in a rotational opening and closing type in an inner space provided in the dispenser body.

A dishwasher for dishwashing has a device for dispensing cleaning agents (detergents and rinses) at different moments of the dishwashing cycle. According to the most widely known method, a chamber for introducing a cleaning agent into the body of a dispenser is formed. The chamber has an airtight cover, and the airtight cover is configured to allow the user to open and close it manually after the detergent is dispensed. At the same time, the opening from the inside of the automatic cycle stroke of the dishwasher is driven by the solenoid provided in the dispenser by the program of the dishwasher The opening and closing operation of the sealing cover is properly controlled. According to the methods known so far in the opening and closing structure of the detergent sealing cover, there are a rotating opening and closing method and a sliding opening and closing method.

Conventional method 1 (rotating switch cover method)

The chamber cover installed on the hinge shaft on the upper surface of the dispenser body of the dispenser body rotates open and closed between the closed position and the open position. This prior art (Fig. 5: picture) has a simple structure, so the opening and closing operation is very easy. When the dispenser chamber cover was opened inside the washer, interference occurred in the internal structure of the dishwasher due to the opening height of the chamber cover, and there was a limitation in the use of the space inside the dishwasher. Dispenser of the type has been developed and used

Conventional method 2 (sliding opening and closing cover method)

A sliding guide is provided along a linear or partially inclined or bent path on the slide guide of the dispenser body of the dispenser body to open and close the chamber cover between the closed and open positions as the detergent chamber cover slides. Publication No. 10-2016- The devices of the above type are disclosed in 0040552 (2016, 4, 14), Publication No. 10-2018-0019659 (2018, 2, 26), but the prior art (Fig. 6) of this sliding cover method is a patented blue ocean technology. However, when the detergent cover slides along the sliding guide provided on the body, the slide must be seated on the top of the detergent chamber without damaging the rubber seal installed on the bottom of the detergent cover. The slide guide curved groove (sliding curve bent downward) must be forcibly pushed and locked. Locking RE has the disadvantage to presenting rubber sealing falling up sliding friction durability

The purpose of the present invention is basically made to solve the problems as described above. In this regard, the feature of the present invention is a rotating cover structure that simply opens and closes the detergent cover portion without imitating the sliding structure of the detergent cover. The purpose is to minimize the protrusion of the detergent cover so that there is no interference (Fig. 7) in the dishwasher's internal devices or dishes.

In order to achieve the above object, the dishwasher dispenser opening and closing device of the present invention comprises a detergent supply unit (FIG. 3) and a rinse supply unit (FIG. 4), and a chamber for receiving and distributing detergent in the detergent supply unit of the dispenser body 1 (FIG. 3) ) And a rotating opening / closing detergent chamber cover (2) sealing the detergent in the detergent chamber (2) consisting of a locking device (Figs. 8, 9) for manually or automatically opening and closing the detergent chamber cover, and as a solution to the problem, the height of rotation of the chamber cover In order to minimize the amount, a detergent chamber cover operating space of a deep groove is provided at the edge of the dispenser body. The rinse supply unit is provided with a rinse supply chamber (FIG. 4), a rinse chamber cover 13, and rinse storage provided on the upper part of the body 1 Body lower cover (18) for rinse distribution valve device (21 ~ 29) mounted on the body lower cover to distribute rinse in suitable cycles. Solenoid device for driving the rinse distribution valve (21 ~ 24) A sensor device (16,17,30) for detecting the rinse amount of the rinse storage tank is provided

Dispenser device for a dishwasher according to an embodiment of the present invention provides the following effects.

First, the present invention is a dishwasher by minimizing the rotational opening height of the detergent cover when the detergent chamber cover is opened in a dishwasher automatic cycle (the dishwasher door is closed) because the detergent chamber cover is mounted inside the dispenser body. Interference can be minimized to the internal device, so that when the detergent cover is opened, it can be prevented from hitting the internal structure or dishes of the dishwasher.

Second, the chamber cover opening and closing device of the conventional method is equipped with a rubber packing on the lower surface of the sliding chamber cover to maintain the airtightness of the detergent, so that the rubber packing is damaged when the chamber cover slides and the straight slide on the chamber cover sealing surface This design has a problem that needs to be seated. Since the detergent chamber cover is reciprocating and rotating, the sealing chamber is excellent in sealing performance, and the rubber packing of the detergent chamber cover is compressed without slide friction.
