[Prior art]
A dishwasher that automatically cleans dishes such as dishes, teacups, cups and the like that have been used for eating and drinking has been installed in a kitchen such as a coffee shop or a restaurant, or a general household, and is preferably used. In this dishwasher, a rack storage portion is defined inside the main body, and in this storage portion, a nozzle set consisting of a cleaning nozzle and a rinsing nozzle is vertically spaced apart from each other. In a state where the rack containing the tableware is stored between the nozzle sets, the tableware is washed and rinsed by the cleaning water and the rinsing water sprayed from each nozzle.
[0003]
In the dishwasher, an operation unit for controlling the operation of the washing machine is disposed in a main body below the rack entrance with respect to the rack storage unit. FIG. 5 shows an arrangement site of a conventional operation unit, in which a case body 14 is inserted through an opening 12 formed in a main body 10 of the washing machine. The case body 14 is housed and arranged with a control board 16 on which operation parts such as switches and display parts such as lamps are arranged, and is fitted to the front side of the rear case 18 and the rear case 18 opened to the front side. The front case 20 is constructed. The front case 20 includes a rectangular frame 20a that can be inserted into the opening 12 and an operation panel 22 that is disposed in an inclined state inside the frame 20a, and includes a rear end portion of the frame 20a. Is fitted to the front end of the rear case 18. Further, an outwardly extending flange 20b is formed at the front end edge of the frame body 20a, and the case body 14 is positioned by the flange 20b coming into contact with the surface of the main body 10.
[0004]
A through hole 22a is formed in the operation panel 22 at a position corresponding to an operation component and a display component disposed on the control board 16, and the rear case 18 is formed on the front surface of the panel 22 from the through hole 22a. An operation label 24 is attached to prevent water droplets or foreign matter from entering. The operator is configured to operate the operation component via the operation label 24 and to confirm the lighting of the display component from the front side of the label 24.
[0005]
[Problems to be solved by the invention]
As described above, in the dishwasher in which the operation unit is disposed below the rack entrance, when the rack is taken in and out of the rack storage unit, the water droplets attached to the tableware and the rack fall and the surface of the main body 10 is removed. It is inevitable that it will be hung. In such a situation, since the operation label 24 that prevents intrusion of water droplets or the like from the through hole 22a is only attached to the operation panel 22, the operation panel 22 is easily peeled off over time. In some cases, a gap is formed between the two, and the water droplets or the like may enter from the gap. At this time, rust is generated on the metal portion of the control board 16, or malfunction or failure is caused.
[0006]
Further, in the structure in which the case body 14 is divided into the front case 20 and the rear case 18, water drops on the surface of the main body 10 flow on the surface of the main body 10 and the flange 20 b and the main body 10 of the case body 14. May enter the inside from the abutting portion and enter the rear case 18 from the fitting portions of the front and rear cases 18, 20, leading to the same problem as described above.
