DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of an operation / display section of a control panel showing an embodiment of the present invention. FIG. 1A shows a state when a course is selected and FIG. 1C shows a cleaning process, FIG. 1C shows a rinsing process, FIG. 1D shows a drying process, and FIG. 1E shows an end of the course. FIG. 2 is a block diagram of a control unit that controls the operation / display unit.

In FIG. 1, reference numeral 23 denotes a course indicator lamp, which comprises a standard course indicator lamp 4 for washing ordinary dirt and a firm course indicator lamp 5 for indicating a course of firm washing for washing heavy oil stains and the like. Reference numeral 6 denotes a course selection button for selecting either a standard or solid cleaning course, and reference numeral 7 denotes a start button for starting / pausing the selected course. Reference numeral 24 denotes a process display lamp for displaying each process of the selected course, and includes the cleaning process display lamp 11, the rinsing process display lamp 12, and the drying process display lamp. Reference numeral 14 denotes an operation / display unit having a display lamp and a bonder as described above. A control unit 21 and a display lamp drive circuit 22, which will be described later, are provided on the back of the operation / display unit. Thus, a control panel is composed of the operation / display unit 14, the control panel control unit 21 and the display lamp drive circuit 22.

In FIG. 2, reference numeral 21 denotes a course selection button 6
A command signal for turning on the course display lamp 23 is output to the display lamp drive circuit 22 in accordance with the cleaning course selected by the input of the command, and a command signal for turning on the process display lamp 24 is sent to the display lamp drive circuit 22. And outputs a start command signal for starting the cleaning course selected by inputting the start / pause button 7 to the main body control device (not shown), and according to the current process. Thus, the control device outputs a blinking signal of the process display lamp 24 to the display lamp drive circuit 22. 22 turns on the course indicator lamp 23 based on the lighting command signal of the controller 21, turns on the process indicator lamp 24 based on the lighting command signal, and blinks the process indicator lamp 24 based on the flashing command signal. This is a display lamp drive circuit.

Next, the operation will be described. The user
First, the course selection button 6 is used to select a standard course for washing ordinary dirt or a firm course for washing heavy oil stains. The control device 21 includes a course selection button 6
, An instruction signal for turning on the course display lamp 23 is output to the display lamp drive circuit 22 in accordance with the selected cleaning course, and the display lamp drive circuit 22 performs the standard course of the course display lamp 23. The display lamp 4 or a selected one of the course display lamps 5 is lit. At the same time, the control device 21 outputs a lighting instruction signal for the process display lamp 24 to the display lamp drive circuit 22, and the display lamp drive circuit 22 turns on all the process display lamps of the process display lamp 24. FIG. 1 shows a case where the standard course is selected, and the display lamp 4 of the standard course is turned on as shown in FIG.

Next, when the start button 7 is pressed, the control device 21 outputs a start command signal for starting the selected cleaning course (standard) to the main body control device, and the standard course starts. . At the same time, according to the current process, a blinking signal of the cleaning process display lamp 24 is sent to the display lamp driving circuit 2.
Output to 2. The display lamp driving circuit 22 blinks the process display lamp 24 based on the blink signal. As shown in FIG. 8, the cleaning process is performed by continuously performing the cleaning process, the rinsing process, and the drying process, and ends.

The display state in each of the above cleaning steps will be described with reference to FIGS. 1 (b), (c), (d) and (e). In FIG. 1B, the cleaning process lamp 11 blinks to indicate that the current process is in the cleaning process. In FIG. 1C, the rinsing process lamp 12 flashes to indicate that the current process is in the rinsing process. In FIG. 1D, the drying process lamp 13 blinks to indicate that the current process is in the process of drying. Next, when all the standard courses are completed, the process display lamp 24 changes to lighting as shown in FIG. The course display lamp indicating the selected process is turned on, the process display lamps of all the processes to be executed are turned on, and the process display lamps in operation are blinked.For example, dirty dishes are added during operation. If it is desired to wash the dishes, it must be performed during the washing process, and if the dishes are to be hand-washed in advance and only drying is to be performed, they must be performed during the drying process. Is displayed, it is possible to achieve excellent usability without losing the timing of storing tableware.

After the start of cleaning, pressing the start / pause button 7 causes a pause, and pressing the button again restarts the operation. In the display in this case, the process display lamp 24 is turned on during a temporary stop, and after restarting, the process display lamp 24 blinks.
