(Configuration of input operation unit)
An input operation unit 60 including a push switch (tact switch) 71 as a command input switch for inputting a command related to operation is provided. The input operation unit 60 is a door body 9 at a location above the front end of the cleaning tank 2. Is disposed on the operation panel P disposed on the upper back side (that is, the rear side portion of the upper portion of the door body 9) (FIGS. 2, 4, 5, 7, 8A, 8B, etc.) reference).

  The input operation unit 60 has a push switch (tact switch) 71 disposed on the substrate (printed circuit board) 73 with the operation unit 72 facing upward, covers the upper side of the printed circuit board 73, and is positioned above the push switch 71. And a key top 63 that covers the opening 61 from above (see FIG. 5, FIG. 9, FIG. 10, etc.). FIG. 5 shows a cross section taken along the line AA of FIG.

An LED 74 for performing various displays on the operation panel P is disposed on the printed circuit board 73 (see FIG. 6 which is a cross section taken along line BB in FIG. 4).
On the upper surface of the cover body 62, an inclined surface 64 is formed which is inclined downward from the front end side to the rear end side of the cleaning tank 2 (see FIG. 10).

The key top 63 swings around a supported portion 66 (FIGS. 8A, 8B, and 12) supported by a support portion 65 (FIGS. 8A, 8B, and 10) provided behind the opening 61. Configured to be possible.
In FIG. 10, the key top 63 is not shown.

  A weir 67 is erected on the left and right and upper peripheral edges of the opening 61 (FIG. 10). The outer shape of the key top 63 has a first operation surface 69A, which will be described later having a substantially rectangular shape in plan view, as an upper surface (FIG. 9), and a hanging wall 77 is suspended from both sides of the left and right sides (FIG. 12). An operation surface that becomes a second operation surface 69B, which will be described later, is suspended from a rear side that is the rear side when attached to the body 62 (FIGS. 11 and 12), and the lower end of the operation surface that becomes the second operation surface 69B Constitutes the supported portion 66 (FIG. 12).

  As shown in FIGS. 11 and 12, the key top 63 is attached to the cover body 62 by inserting an operation piece 68 projecting below the key top 63 into the opening 61 from above, as shown in FIGS. 8A and 8B. The key top 63 is configured to cover the upper part of the opening 61 and the weir 67 in the range of swinging of the key top 63.

  In the range of swinging of the key top 63, the left and right hanging walls 77 are located on both sides of the left and right dam portions 67, and the key top 63 surrounds the left and right dam portions 67 and the opening 61. It is configured to cover from above.

  From the state of FIG. 8A in which the operation piece 68 does not press the operation portion 72 of the push switch (tact switch) 71, the state of FIG. 8B is reached by swinging with the supported portion 66 of the key top 63 as a fulcrum. The operation piece 68 projecting downward presses the operation part 72 of the push switch 71 to operate the push switch 71 and input it to a control part (not shown).

  Since the above-described configuration is provided, when water is applied from above the input operation unit 60, the applied water flows outside the weir portion 67 on the inclined surface 64 toward the cleaning tank. Since the key top 63 surrounds the opening 61 and covers from above, the water does not enter from the opening 61 and the push switch (tact switch) 71 does not get wet. The push switch 71 can be a small non-waterproof push switch that is generally commercially available.

  Further, when water is applied from above the input operation unit 60, the water flows toward the washing tank 2 side (the rear side of the input operation unit 60) and flows into the washing tank 2, so that the water flows into the dishwasher main body. 1 is not leaked out and can be discharged out of the machine together with hot water for cleaning by a drain pump (not shown).

By performing an operation of pressing either the first operation surface 69A or the second operation surface 69B, the key top 63 swings about the supported portion 66 as a fulcrum and the push switch (tact switch) 71 is operated.

  That is, since the push switch (tact switch) 71 is operated by swinging the supported portion 66 of the key top 63 as a fulcrum, the user can either swing the key top 63 using the supported portion 66 as a fulcrum. In the operation from the direction (operation from any direction of the first operation surface 69A or the second layer operation surface 69B), the key top 63 can be operated to input a command related to the cleaning operation to the control unit.

  As described above, since the operation surface of the key top 63 is not limited to one, the operability can be improved.

  The key top 63 is formed with a recess 75 surrounded by the operation piece 68 and the supported portion 66, and the thick wall formed on the rear side of the opening 61 when the key top 63 is attached to the cover body 62. The portion 76 fits into the recess 75 while elastically deforming the operation piece 68.

  For this reason, when the key top 63 is removed from the cover body 62, the operation piece 68 needs to be elastically deformed because the thick portion 76 comes out of the recess 75, and the key top 63 is prevented from being detached from the cover body 62. .

  Moreover, in this embodiment, when the door body 9 is attached to the front surface of the cleaning tank 2, a gap G is formed between the input operation unit 60 and the door body 9.

  Thereby, in this embodiment, the above-mentioned handle 8 is sandwiched between the front surface of the door body 9 facing the gap G and the rear surface of the door body 9 facing the gap G at the upper part of the door body 9. A different type of handle 8A can be attached. (FIGS. 13 and 14)
