Description

[Detailed description of the invention] The present invention relates to a dishwasher with a front-opening door, and is designed to ensure that the machine operating switch is operated correctly when opening and closing the door. The purpose is to

Dishwashers with front-opening doors eject water into the washing tank, and most dishwashers use high-temperature water for washing, so when the door is opened,
It is important that the hot water in the cleaning tank stops gushing out.

However, since this type of jetting action is generally performed using a pump, even if the aircraft operation switch is turned off and the power to the motor is stopped, the inertia of the pump runner, motor, etc. will still cause the water to scatter for a while. Sometimes there is something to be done.

For this reason, when it comes to dishwashers, the user has to switch hands to turn off the switch and open the door, and the door can be opened after a short period of time after the switch is turned off. There are many things.

However, in the past, the handle and the body switch were often located close to each other because the body switch was turned on and off in conjunction with the opening and closing of the door.

Therefore, it has not been possible to sufficiently prevent water from spouting out due to the inertia of the runner as described above.

The present invention solves the above-mentioned conventional drawbacks without impairing the operability of the door and the switch for operating the aircraft, and an embodiment thereof will be described below.

In the figure, reference numeral 1 denotes a washing tank, in which water discharged from a pump (not shown) is ejected into the tank by rotation of a motor (not shown) to wash tableware.

A main body 2 surrounds the cleaning tank 1 except for its front opening.

Reference numeral 3 denotes a door whose lower end is pivotally supported by a horizontally long shaft 3a so as to open and close the front opening of the cleaning tank 1.

Reference numeral 4 denotes a lever rotatably supported on the lower part of the main body 2 of the door 3, and the shaft center portion 5 provided at one end of the lever is inserted without rotation into a rotating piece 6 having a cylindrical shape. Furthermore, this rotating piece 6 is integrally provided with a rectangular prism-shaped angle regulating part 7 and an arm part 8.
is formed.

Reference numeral 9 denotes a cover that rotatably supports the rotating piece 6 and surrounds the angle regulating portion 7, and is fixed to the main body 2.

Reference numeral 10 denotes a spring plate located inside the cover 9 and in pressure contact with the angle regulating part 7, which urges the angle regulating part 7 together with the lever 4 to rotate sharply at an angle of 90 degrees.

By rotating the lever 4, the lever 4 can be turned to face the lower front end of the door 3 to obstruct the opening and closing of the door 3, as shown in FIG. By rotating the lever 4, the lever 4 can be moved to a position where it does not face the lower front end of the door 3, so that opening and closing of the door 3 is not obstructed.

Reference numeral 11 designates a mounting portion for an aircraft operation switch 12 extending downward from the rear end of the cover 9.

The switch 12 has an operating section 12a for connecting and separating internal contacts, and this operating section 12a is connected to the arm section 8.
Correspondingly, in the position of the lever 4 as shown in FIG. 2, the operating portion 12a is pressed by the arm portion 8, the motor is started, and the cleaning water is splashed by the pump.

According to the above configuration, the lever 4 for operating the switch 12 is
It can be rotated between a position that inhibits the opening and closing of the door 3 and a position that does not inhibit the opening and closing of the door 3, and when opening the door 3, the power to the switch 12 is cut off by operating the lever 4. If not, the door 3 will be prevented from opening by the lever 4, and therefore the door 3 will be opened while making sure to turn off the switch 12.

Furthermore, when starting operation, it is possible to rotate the lever 4 and turn on the switch 12 after fully closing the door 3, and the opening/closing operation of the door 3 and the rotation operation of the lever 4 are completely separated. This prevents water from spewing out due to the inertia of motors, runners, etc., which previously occurred.

As described above, according to the present invention, the door opening/closing operation and the cleaning operation switch operation are completely separated, which eliminates the problem of cleaning water generated when the door is opened due to the inertial operation of the pump motor, runner, etc. This provides effects such as being able to reliably prevent the ejection of water, and also allowing accurate operation control of the opening/closing operation of the door with a simple configuration.
