Description

Dishwasher Dispenser

The present invention relates to a dispenser of detergent for washing household appliances, in particular a dishwasher, and has been developed in connection with a dispenser having a sliding detergent lid 31.

Household appliances, especially dishwashers, for cleaning typically have a device for dispensing the cleaning agent. In general, the cleaning devices are provided with two other cleaning agents in liquid form (detergent and liquid rinse additive) at different moments in the dishwashing cycle. Provided for dispensing.

According to the most widely known method, a chamber for introducing a cleaning agent into the body of the dispenser is formed. The chamber has an airtight cover, and the airtight cover is configured to be opened and closed manually by the user after the detergent is dispensed. Opening in the interior is properly controlled by the program of the household appliance opening of the cover

According to a known method, the closure lid is slidably constrained to the body of the dispenser so that it can slide along a substantially linear or at least partially inclined or curved path between the closed position and the open position.

To this end, corresponding sliding guides are provided which interact between the body of the dispenser and the body of the lid. Publication No. 10-2016-0040552 (2016, 4, 1) Publication No. 10-2018-0019659 (2018, 2, 26) discloses devices of this type.

However, this prior art (FIG. 3), while the chamber cover slides along the sliding guide provided in the body, should be slide-mounted to the upper side of the chamber without damaging the rubber packing installed on the bottom of the chamber cover and at the same time maintain the detergent sealing property. The chamber cover must be pushed by hand to the sliding guide curved groove of the body (curved down) to unlock the chamber cover. Complex structure needed

The object of the present invention is basically made to solve the problems as described above. In this regard, a feature of the present invention is to eliminate the inconvenience of manually pushing the detergent cover closed by locking and by simply pressing the switch button To effectively provide a detergent dispensing dispenser device that is properly controlled by using a drive motor to provide automatic opening of the detergent sealing lid in the manual opening and closing of the automatic dispensing cycle (Fig. 4, Fig. 5, Fig. 6).

In order to achieve the above object, the dishwasher dispenser opening and closing device of the present invention has a dispenser body 30 and the body 30 having chambers 30-1 and 30-5 for receiving and dispensing detergent and rinse. The chamber cover slide device 31 for opening and closing the detergent in the chamber while sliding the reciprocating motion in the sliding guide portions 30-2 and 30-3 of the). A device for reciprocating the slide (Fig. 4, Fig. 5) Rinse storage tank carver 46 attached to the rinse cover attached to the rinse (Rinse) storage space is provided in the lower portion of the body 30, the appropriate cycle rinse Dishwasher dispenser equipped with a solenoid device (Fig. 6) for controlling the dispensing valve unit

Dishwasher dispenser device according to an embodiment of the present invention is to be made automatically the conventional structure in which the detergent chamber cover is opened and closed by a manual operation. The dishwasher dispenser device according to the present invention provides the following effects.

First, the present invention can easily open and close the chamber cover of the detergent part automatically by simple pressing operation of the switch button. The conventional manual operation method is a structure that slides the chamber cover by hand and causes sliding locking, resulting in very inconvenience in operability.

Second, the conventional chamber cover opening and closing device has a problem that the manufacturing cost increases due to a difficult process of installing the rubber packing on the slide surface because the rubber packing is mounted on the lower part of the chamber cover to maintain the sealing of the detergent. The rubber packing is damaged during the slide operation. The present invention provides automatic driving of the chamber cover and surface contact (polishing) sliding friction between the upper surface of the chamber part of the body and the lower surface of the chamber cover. No parts such as packing are needed (Figure 7)

Third, the surface of the detergent is sealed by the surface contact, but the surface is compressed by the leaf springs provided on both sides of the body slide part and the upper part of the chamber cover, and the detergent is very easily sealed by the adhesion of the detergent. Surface friction of each slide surface is made very easy by rolling ball bearings installed in the upper left and right corners of the chamber cover in order to reduce the friction (Figs. 8 and 9).
