(a) Consists of a casing with an opening and a function to automatically wash dishes, and a door that opens and closes this opening.

(b) A control member shall be installed at the end of the door to control the work procedure for washing dishes.

(c) The control member shall be covered by a protrusion that protrudes from the housing when the door is closed.

[Function] The dishwasher having the above configuration can be used as follows.

Open the door and store the dishes to be washed inside the cabinet.
The work procedure for washing dishes is controlled by operating a control member provided at the end of the door. Then, by closing the door, the dishwasher operates according to the above operating procedure. During operation of the dishwasher, the control member is covered by the projection so that it cannot be operated accidentally.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 2 to 4.

A is a dishwasher, which is composed of a housing 1 having a workbench 2 on the top and a door 3 on the front opening. This dishwasher A is interlocked so that it automatically stops operating when the door 3 is opened. The only control member provided on the front panel 3a of the door 3 is the on/off switch 7. This on/off switch 7 can stop the electrical operation of the dishwasher A without opening the door 3. The workbench 2 has a protruding part 5 formed by protruding the front part thereof on the door 3 side, and the protruding part 5 is formed so as to cover the upper end part 4 of the door 3. A control member 8 is provided at the upper end portion 4 covered by the protrusion 5 . To explain the upper end portion 4 in more detail with reference to FIG. 3, a step recess 14 is formed in the upper end 4 of the door 3 covered by the protrusion 5, and the lower surface of the step recess 14 touches the control panel 4a. Configure. A control member 8 is provided on this control panel 4a. The control member 8 has a plurality of push buttons 10 for controlling the dishwashing procedure and a switch 16 operated by the push buttons 10. That is, the control panel 4a is provided with a plurality of circular holes 12a that communicate with a space 17 formed in the door 3 at predetermined intervals, and a peripheral wall 12 that stands upright along the circular holes 12a. The switch 16 is housed within this space 17. The push button 10 consists of an upper wall 10b having a top surface 10a to be pressed, a peripheral wall 10c provided below the periphery of the upper wall 10b, and a bearing boss portion 10d protruding from the back surface of the upper wall 10b. The stem 11 is fitted into this bearing boss portion 10d. The lower end of the stem 11 of the push button 10 passes through the circular hole 12a and comes into contact with the upper end of the switch 16 so that the top surface 10a of the push button 10 is flush with the upper end 4 of the door 3.
The upright peripheral wall 12 is loosely fitted into an annular groove 13 formed around d. Furthermore, a cover (not shown) having a transparent portion through which the indicator can be seen may be attached to the push button 10.

Since one embodiment of the present invention has the above configuration, it can be used as follows.

Open door 3 when dishwasher A is not running,
A switch 16 is controlled via a plurality of push buttons 10 to select a dishwashing procedure. Dishwasher A is
Since the operation is automatically stopped when the door 3 is opened, even if it is in operation, the operation is temporarily interrupted, and preferably the door 3 should not be opened while it is in operation. When the door 3 is closed after selecting the above dishwashing procedure, the insulation is released and the machine is ready for operation at any time. At this time, the plurality of push buttons 10 cannot be touched because they are covered by the protrusion 5, and depending on the design of the door 3 or the push buttons 10, these may be covered or hidden. , or only partially visible. Next, the on/off switch 7 provided on the front panel 3a of the door 3 is turned on to release the electrical insulation of the dishwasher A, thereby allowing the dishwasher A to operate. Dishwasher A will operate according to the dishwashing procedure controlled by switch 16. Since the push button 10 has a configuration in which the peripheral wall 10c thereof covers the upright peripheral wall 12 of the control panel 4a, even if water spills on the control panel 4a, the water will flow from there to the lower switch 1.
6 or flow into the space 17.

The configuration of the preferred embodiment shown in FIG.
AUSTRALIA (Australian Standards Association) Test Specification 3184-1972 electrical test.
There is no need for rubber seals which normally show wear with continuous use.

Furthermore, compared to providing a control member on the front panel of the door, the lack of a control member makes it easier to wipe the front panel clean, and the overall appearance of the dishwasher is good.

In accordance with SAA specification 3184, this dishwasher A was placed on a horizontal surface and 200 cm ³ of water was poured onto the center of the control panel 4a for 15 seconds. According to subsequent tests,
Water is not found in electrically active or insulating parts, and
The electrical resistance did not fall below the permissible limit (1 megohm at 500V).

In addition, an inclined surface 15 is provided at the front part of the upper part of the step recessed part 14.
An auxiliary panel 15 may be provided to prevent water from flowing into the surface of the stepped recess 14, that is, the control panel 4a. This auxiliary panel 15
is formed integrally with the front panel 3a,
Of course, it may be configured to become a part of the front panel 3a.

Further, for example, if a band-shaped recess is formed in the upper end 4 of the door 3 and the control member 8 is installed in the recess, the control member 8 cannot be seen from the outside when the door 3 is closed, but the upper end of the front panel 3a If the band-shaped areas in the vicinity of 4 are made transparent or semi-transparent, the operating state can be seen from the outside, which is very convenient. That is, a band-shaped area near the upper end 4 of the front panel 3a may be made into a transparent or semi-transparent part, so that the control state of the control member 8 can be confirmed through this transparent or semi-transparent part. Furthermore, a display section 18 for displaying the operating status of the dishwasher A in use is provided at the rear of the push button 10, and if the display section 18 is illuminated by a known lighting means provided inside the door 3, the display section 18 can be displayed on a transparent or semi-transparent section. Confirmation of the control state of the control member 8 from the transparent part is further improved. In the case of the above embodiment, the auxiliary panel 15 may be made transparent or semi-transparent as a band-shaped region.

The door 3 does not necessarily have to be hinged at its lower end or provided with a control member 8 at its upper end. For example, the control member 8 can be provided at the side or lower end of the door 3. In this case, the protrusion formed around the front opening of the housing 1 allows
What is necessary is to cover the control member 8.

[Effects of the Invention] The dishwasher according to the present invention is provided with a control member for controlling the work procedure for washing dishes at the end of the door, and is covered by a protrusion that protrudes from the casing when the door is closed. Therefore, there is an effect that the device cannot be easily operated by a child, nor can it be operated by mistake during operation. In addition, since the control member is provided at the end of the door, there is no need to secure extra space for the control member, and the front panel has a beautiful appearance, making cleaning very easy. . Furthermore, since the control member is covered by the protrusion, there is an advantage that there is less of a disadvantage that water is directly splashed onto the control member. In particular, when the control member is provided at the upper end of the door, the control member can be easily operated and water is less likely to come into contact with the control member.

In addition, by making the front panel of the door near the position where the control member is transparent or semi-transparent, the control member can be seen through the transparent or semi-transparent part, and furthermore, the control member can be seen through the transparent or semi-transparent part. This has the effect that the display section that displays the control status of the door can be seen more clearly by means of the light emitting or illuminating means provided on the door. Furthermore, since the switch operating member constituting the control member is shaped to cover the entire hole formed in the control panel, there is an effect that the risk of water entering the inside of the door is extremely reduced.
