SUMMARY OF THE INVENTION The present invention is directed to a main body having a washing chamber formed therein, a dish basket provided in the washing chamber, a dish washing nozzle provided in the washing chamber, and a washing device. In a dishwasher equipped with a wash water circulation passage from the bottom of water to the nozzle and a pump interposed in this circulation passage and pressurizing the wash water to spray from the nozzle, a detergent container attached to the washing chamber And an operation flow path that communicates with the cleaning water circulation flow path and has an opening corresponding to the detergent container, and a cleaning water that is provided in the vicinity of the opening and is pressed into the opening so as to be retractable so as to open the detergent container. Disclosed is a dishwasher including an operating piece that can put detergent into a washing room.

That is, according to the present invention, a specific actuating piece is caused to project and move by utilizing the jetting pressure of washing water, and the detergent container is forcibly opened by the projecting movement so that the detergent can be put into the washing chamber. Therefore, the detergent injection can be automated with a very simple configuration without using a drive source such as a solenoid. More specifically, in the present invention, since the jetting pressure of washing water is used as a drive source for projecting and moving the operating piece, a solenoid is not required and
It eliminates the need for a control device and electrical components required with the use of the solenoid, and also eliminates a mechanical component for transmitting the solenoid operation. Of course, since the structure of the operating piece and the operating flow path of the present invention can be designed to be small, almost no new installation space is required, and since the structure is extremely simple, there are few failures and maintenance is easy.

Here, the detergent container is opened by the actuating piece that moves protrudingly contacting the detergent container directly or indirectly to invert the detergent container and / or open the lid or stopper of the detergent container. It will be possible. As an example in which the operating piece indirectly contacts the detergent container, as shown in the embodiment, there is a configuration in which the opening operation is transmitted to the detergent container through a contact plate (abutting plate) integrally provided in the detergent container. You can

When the detergent container is opened by reversing the detergent container, the detergent container can be rotated to a dish basket or other portion in the washing chamber (for example, an outer wall of the washing water circulation passage or the working passage). Can be mounted (freely). In this case, the detergent container and the operating piece may be arranged so as to come into contact with the detergent container when the operating piece projects and thereby be inverted so that the projecting movement of the operating piece is transmitted to the detergent container.
That is, there is no need for a mechanism for connecting the two.

On the other hand, when the detergent in the detergent container is released by opening the lid or the stopper of the detergent container, the lid or the stopper seals the bottom portion or the side portion of the detergent container, and the moving operating piece is the lid or the stopper. Abut the stopper and open it. The shape of the detergent container is not particularly limited as long as it is a container that can be filled with detergent (liquid, powder, etc.), but if the detergent container discharges the detergent by reversing, there is no lid or it can be opened and closed as in the embodiment. It is preferable to use a container with a lid.

On the other hand, if the operation piece has an injection port formed at its tip, the cleaning water can be ejected from the injection port, whereby the tableware in the table basket can be cleaned, and the operation piece serves as a nozzle for cleaning the tableware. be able to. The dishwasher according to the present invention has, as a basic configuration, a main body having a washing chamber formed therein,

The tableware basket 4 on the top can be washed.
It is possible to simplify the structure by eliminating the need to newly provide a nozzle for a. However, the ejection function of the upper tableware basket 4a may be obtained by another member (for example, a nozzle such as the arm-shaped nozzle 5 is provided above the upper tableware basket 4a).

[0017]

According to the present invention, the pressure of washing water is used to cause a specific operation piece to move in a protruding manner, and the protruding movement causes the detergent container to be forcibly opened so that the detergent can be put into the cleaning chamber. Therefore, the detergent injection can be automated with a very simple structure without using a drive source such as a solenoid. Moreover, the mechanism is simplified and the electric parts are eliminated, so that the number of failures is reduced and the maintenance management is facilitated. In addition, the detergent container is started by the rising pressure of the washing water, and the detergent is added by the supply of the washing water when the washing is started.Therefore, the detergent is surely added when washing without considering the supply timing. can do.

Further, the detergent container is rotatably attached to the tableware basket, and the detergent container is configured to be inverted by the contact of the operating piece, thereby eliminating the need for a connecting mechanism for transmitting force between the detergent container and the operating piece.
