However, detailed description of the structure is omitted.

In the front of the washing room 1, an entrance 5 for opening and closing tableware a is opened so as to protrude toward the front, and a door 6 is provided at the entrance 5. This door 6
A protruding wall 7 is provided along a peripheral edge on the inner surface side, and a lower edge (not shown) is swingably supported by a lower edge side of the entrance 5. Then, as shown in FIG. 2, the upper edge side is opened by pulling forward and tilting the upper edge side, and when the upper edge side is raised, as shown in FIG. And is airtightly closed via a packing 8 attached thereto. Tableware a to be washed is placed on a tray or the like from the entrance 5 and is put in and out of the washing room 1.

An operation panel 10 is provided above the entrance 5 at the front of the washing room 1. The operation panel 10 is formed in an elongated box shape in the left-right direction, and various electric components 11 necessary for controlling a cleaning process are mounted on the substrate 12 and accommodated therein. .

The bottom plate 14 of the operation panel 10 has an inclined surface whose rear surface is inclined obliquely downward. The rear edge of the bottom plate 14 is suspended by a certain dimension over the entire width, and further extends rearward in parallel with the bottom plate 14. As a result, the mounting piece 15 is formed. On the other hand, a bracket 17 is attached to a position immediately above the entrance 5 on the front surface of the cleaning room 1. The bracket 17 has a substantially L-shaped cross section in which a mounting plate 19 whose front end side is inclined obliquely upward is provided at the upper edge of the rising plate 18, and the rising plate 18 is applied to the entire surface of the cleaning chamber 1. It is fixed. Then, the mounting piece 15 of the operation panel 10 is applied to the lower surface of the mounting plate 19 of the bracket 17, and the operation panel 10 is stopped by screws 20 at three convenient positions at both ends and a center in the length direction. 10 is mounted so as to be flush with the front surface of the door 6 whose front surface is closed. Various switches (not shown) are provided on the front surface of the operation panel 10. A top plate 22 extends from the upper surface of the operation panel 10 to above the cleaning chamber 1.

Now, the bottom plate 14 of the operation panel 10 described above.
A steam contact prevention plate 24 is arranged between the tableware a and the entrance 5 of the tableware a. As shown in FIG. 3, the steam contact prevention plate 24 has a length substantially equivalent to the width of the operation panel 10, is formed in a stepped shape bent in the middle in the width direction, and has a front side. An abutting portion 25 for steam having a width substantially equal to the depth of the operation panel 10 is provided, and a rear portion is an attachment portion 26. The front end of the abutting portion 25 is folded back on the upper surface side and overlapped. On the other hand, the mounting portion 26 is cut out at both ends in the longitudinal direction and at a central portion so as to open to the rear edge. An insertion hole 27 of the screw 20 having a long hole shape is formed.

When attaching the steam contact preventing plate 24, first, as shown in FIG.
Temporarily fasten with the book screw 20. Then, the mounting portion 26 of the steam contact prevention plate 24 is inserted as shown by the arrow in the same figure with the insertion hole 27 aligned with the screw 20, and then the screws 20 are fully tightened and so-called jointly tightened. Thereby, the operation panel 10 and the steam contact prevention plate 24 are fixed together with the bracket 17. At this time, as shown in FIGS. 1 and 2, the abutting portion 25 of the steam contact preventing plate 24 assumes a forwardly inclined oblique posture parallel to the bottom plate 14 of the operation panel 10.
Further, the abutting portion 25 blocks the entire lower surface of the bottom plate 14 of the operation panel 10. A fixed space is provided between the abutting portion 25 of the steam contact prevention plate 24 and the bottom plate 14 of the operation panel 10, and an air layer 29 serving as a heat insulating layer is formed therebetween.

This embodiment has the above structure, and its operation will be described below. When cleaning the tableware a, first, the door 6 is pulled forward and opened, and then the tableware a to be cleaned is placed on a tray or the like and stored in the cleaning room 1 from the entrance 5 and then the door 6 is opened. Raise and seal. In such a state,
Washing is performed by spraying washing water from the washing nozzle 2 toward the tableware a, and then, as shown in FIG. Rinsing is performed by being sprayed. At this time, high-temperature steam is contained in the cleaning chamber 1.

After the rinsing is completed, the door 6 is opened to take out the tableware a. Thereby, as shown in FIG. 2, the steam m in the cleaning chamber 1 rises out of the entrance 5 and rises, but the steam m strikes the butting portion 25 of the steam contact preventing plate 24, and this abutting portion 25 Since the steam m is inclined obliquely upward, the steam m quickly flows toward the distal end along the slope without stagnating on the lower surface of the abutting portion 25, and the distal end of the abutting portion 25 is Of the operation panel 10 from the tip of the abutment 25.
It is discharged toward the front side of. In addition, the steam contact prevention plate 2
4 and the bottom plate 14 of the operation panel 10 are spaced apart from each other, and an air layer 29 is formed between them, so that the air layer 29 functions as a heat insulating layer and makes contact with steam. The transfer of the heat of the steam m on the lower surface of the prevention plate 24 to the operation panel 10 is effectively prevented.

As described above, according to the present embodiment, the steam m rising from the entrance 5 when the door 6 is opened hits the abutting portion 25 of the steam contact prevention plate 24 and escapes in front of the operation panel 10. As a result, direct contact with the operation panel 10 is prevented, and no heat is trapped on the lower surface side of the steam contact prevention plate 24.
By providing the heat insulating layer between the heat insulating layer 24 and the heat insulating layer 0, the operation panel 10 is also prevented from receiving the heat of the steam m from the lower surface side of the steam contact preventing plate 24 as much as possible. Thereby, the operation panel 1
0 is exposed to a high temperature and steam is prevented from entering the panel 10.
1 is prevented from deteriorating, and the maintenance burden is greatly reduced. When the operation panel 10 is made of synthetic resin, the panel 10 is prevented from being deteriorated or discolored, and its commercial value is maintained for a long period of time.

Further, the structure of the mounting portion of the steam contact preventing plate 24 is such that the mounting piece 15 of the operation panel 10 is overlapped on the lower surface of the mounting plate 19 of the bracket 17, and the mounting portion 26 of the steam contact preventing plate 24 is further stacked. Since the screw 20 is screwed together, if the hole for inserting the screw 20 of the steam contact prevention plate 24 is merely a circular hole or a long hole, the hole is inserted into the screw hole of the operation panel 10 and the bracket 17. Since the screws 20 must be screwed through the three plates,
Work is extremely difficult. In this regard, in this embodiment, since the insertion hole 27 of the screw 20 of the steam contact prevention plate 24 is formed as a cutout opening on the rear edge side, as described above, the operation panel 10 is attached to the bracket 17 first. After temporary fixing at 20, the steam contact preventing plate 24 may be inserted and fully tightened, so that the steam contact preventing plate 24 can be easily attached.
