Description of the Related Art Conventionally, there is a dishwasher in which an operation control means is provided with a microcomputer, an operation mode is set in the microcomputer by course setting means, and the microcomputer is operated based on the set operation mode. Some items control washing, rinsing, and drying. That is, it has a plurality of operation courses in which the washing step, the rinsing step, the drying step, etc. are combined so that the time of each step is different, and based on the operation of the operation course selection switch, any one of the plurality of operation courses is selected. Is executed.

[0003] Examples of the driving courses include a speedy driving course, a standard driving course, a careful driving course, and a drying-only driving course. Speedy driving course, standard driving course, careful driving course, washing process,
This is an operation course in which a series of steps of a rinsing step and a drying step are performed, and the time of each step is determined so that the user can use the table depending on the degree of contamination of the dishes. Also, the drying-only driving course is different from the above-mentioned driving course,
This is an operation course specified so that the user can only wash the dishes and the like hand-washed by the user without performing the washing step and the rinsing step.

FIGS. 5 and 6 show the structure of a conventional operation panel. When the user sets a desired operation course in the configuration of the operation panel shown in FIG. 5, the user presses the cleaning course selection switch 43 and presses the cleaning course selection switch 43 until the desired operation course is obtained. Set. Further, when the user sets a desired driving course in the configuration of the operation panel shown in FIG. 6, the user presses any one of the driving course selection switches 52 corresponding to the desired driving course, and sets the desired driving course. Set the course.

In many cases, the same operation course is selected every time when the user uses the dishwasher and drying machine. Therefore, in the configuration of the operation panel shown in FIG. , Power on / off switch 41
When the power is turned on by pressing, the course used last time is displayed, and there is a case where the washing course selection switch 43 does not need to be pressed when the same course as the previous time is used.

[0006] However, even if the same course is used to set a series of steps of washing, rinsing, and drying steps by setting dirty dishes, it is desired to dry hand-washed dishes by performing only the drying step. In some cases or at the end of a series of steps (washing, rinsing, drying step), it may be desired to perform only the drying step again. In this case, when performing only drying, the cleaning course selection switch 43 is pressed to select the drying only course, and the operation of the drying only course is performed. When the next cleaning is performed, the previously used course is used as described above. Is displayed, only the drying course is displayed, and at this time, the desired operation course (course for performing the washing, rinsing, and drying steps) is set by pressing the cleaning course selection switch 43. There was a problem that it became troublesome.

In the configuration of the operation panel shown in FIG. 6, a switch 52 is assigned to each of a plurality of operation courses, and after the power on / off switch 51 is turned on, any one of the operation course selection switches 52 is selected. Since the driving course can be selected by pressing any of the switches, the troublesome operation of the switch of the driving course selection switch configuration as shown in FIG. 5 is eliminated.
There is a problem in that switches are assigned to a plurality of driving courses, and the number of switches increases, which causes a cost increase.

The drying only course selection switch 33 is a dedicated operation selection switch that can set “drying only”, which is a dedicated operation course that cannot be selected by the operation course selection switch. 3
Reference numeral 6 denotes a power lamp which is turned on when the power is turned on, 37 denotes a drying only course lamp which is turned on when "drying only" is selected, 38 denotes a cleaning course lamp which turns on the selected cleaning course, 3
A drying course lamp 9 turns on the selected drying course.

[0011] Also, "speedy", "standard",
The “Careful” cleaning course is a course for performing a series of operations of a washing step, a rinsing step, and a drying step, and the “drying only” course is a course for performing only a drying step. , "Hot air 60 minutes" is a course for drying for 15 minutes and 60 minutes by warm air heated by a heater, and "Blow" is a course for blowing air without heating the heater.

When the user uses the dishwasher / dryer, the dishes are set in the main body of the dishwasher / dryer, and the power on / off switch 31 is pressed to turn on the power. , 35
By pressing the start / pause switch 32 after the selection, a series of operations is started. At that time, wash,
When selecting a course for performing a series of steps of rinsing and drying, the washing course selection switch 34 is pressed until the lamp 38 of the desired washing course is turned on, and the drying course selection switch 35 is similarly turned on. The course is selected by pushing until 39 lights up.

When the operation is performed by selecting a washing / drying course and using a dishwasher on the next day or the like, when the power is turned on by pressing the power on / off switch 31, Since the previously used washing / drying course stored in the microcomputer 21 is turned on, the user presses the power on / off switch 31 to select the same washing / drying course as the previous one, and starts. It is only necessary to press the / pause switch 32.

When it is desired to dry the hand-washed tableware by performing only the drying step or to perform only the drying step once again at the end of a series of steps (washing, rinsing, drying step), “drying only” is selected. I will select and drive,
In the present invention, as shown in FIG.
In order to select the "drying only" course, the user only needs to press the power switch 31 to turn on the power, then press the drying only selection switch 33 and press the start / pause switch 35.

The washing / drying course which is turned on when the power is turned on again after executing "drying only" is set so that the setting at the time when the previous cleaning course such as the speedy course, the standard course, or the careful course is used is turned on. Therefore, when using a course that is always used ("speedy", "standard" or "careful"), it is only necessary to press the power on / off switch 31 and the start / pause switch 32.

Before describing the above operation using the flowchart of FIG. 4, the variables in FIG. 4 will be described first. The variable MODNO means the currently selected cleaning course, and the speedy course is selected. MODN if available
O = 0, MO when standard course is selected
DNO = 1, MODNO = 2 when the careful course is selected, and MODNO = 3 when the drying only course is selected. Also the variable DRYNO
Means the currently selected drying course, and if the hot air 15 minute course is selected, DRYNO = 0,
DRYNO = if the hot air 60 minute course is selected
1 and DRYN when the ventilation course is selected
O = 2.

The variable MODBF is a variable for storing the course selected by the previous cleaning selection switch.
Its value is the same as the variable MODNO, MODBF = 0 for speedy course, MODBF = 1 for standard course, MO
DBF = 2 means that the elaborate course was selected last time, and is programmed so that MODBF ≧ 3 is not satisfied. The variable DRYBF1 is a variable that stores the drying course selected by the drying selection switch when the last time other than the drying only course is selected.
BF1 = 0 means hot air 15 minutes course, DRYBF1 = 1 means warm air 60 minutes course, DRYBF1 = 2 means air blowing course has been selected, and variable DRYBF2 means dry selection when previous drying only course was selected. This is a variable that stores the drying course selected by the switch.

Next, the actual program operation will be described with reference to the flowchart of FIG. When power is supplied to the control circuit of FIG. 2, the microcomputer 21 is reset, and in step 61, the CPU 21a starts executing the program from the head address of the program stored in the ROM 21b. In the next step 62, MODBF, DR
Initial values are stored in YBF1 and DRYBF2. The numerical values stored in this step are MODBF = 0, DRYB
F = 0, DRYBF2 = 1 The washing / drying course lamp that lights up when the power is turned on for the first time is "Speedy", "Hot air 15 minutes", and turns on when "Dry only" is selected for the first time. Drying course lamp "Hot air 60
Minutes ”. Step 63 is a step of determining the input of the power on / off switch, and the processing of step 63 is repeated until there is an input of the power on / off switch.

In step 64, MODBF, DRYBF
The value stored in 1 is changed to the cleaning
Read in MODNO and DRYNO to make a drying course. In step 66, it is determined whether or not the drying only selection switch has been pressed.
If it is determined that the drying only selection switch has not been pressed, it is determined in step 67 whether or not the drying cleaning selection switch has been pressed. If the cleaning selection switch is not pressed, the process proceeds to step 72. If the cleaning selection switch is pressed, +1 is added to MODNO in step 68. If the addition result after the processing in this step becomes 3 or more, The value is returned to 0 in the processing of steps 69 and 70. These 6
Each time the cleaning course selection switch is pressed in steps 7 to 70, MODNO is sequentially changed within the range of 0 to 2. In the next step 71, the currently selected cleaning course, that is, the value of MODNO is stored in the MODBF. In step 72, where the cleaning selection switch has not been pressed, it is determined whether the drying selection switch has been pressed. If the drying selection switch has not been pressed, the process proceeds to step 77, but if the drying selection switch has been pressed, the DRYNO
When the addition result after the processing of this step of adding 1 becomes 3 or more, it is returned to 0 in the processing of steps 74 and 75. Each time the drying course selection switch is pressed in these steps 72 to 75, DRYNO is sequentially changed within the range of 0 to 2. In the next step 76, the currently selected drying course, that is, the value of DRYNO is set to DRY.
This is stored in the BF.

In step 77, when the drying selection switch is not pressed, the lamp corresponding to the currently selected cleaning / drying course, that is, MODNO or DRYNO is turned on. Step 78 is a step of judging whether or not the start / pause switch has been pressed. If the start / pause switch has been pressed, the flow proceeds to the next step 79, the cleaning step 79, the rinsing step 8
0. After the drying step 81 is sequentially executed and the drying step is completed, all lamps are turned off in step 82, the power is turned off in step 83, and the process returns to step 63. If the start / pause switch has not been pressed in step 78, the flow advances to step 66 to execute the processing in steps 66 to 78 again.

The case where the drying only selection switch is pressed in step 66 and the process proceeds to step 84 will be described below. In step 84, MODNO = 3 because the “drying only” course has been selected, and the value stored in DRYBF2, that is, the drying course selected when the “drying only” course was previously selected is set as the drying course to be displayed this time. Therefore, it is stored in DRYNO. In steps 85 to 88, DRYNO is sequentially changed each time the drying course selection switch is pressed, as in steps 72 to 75. However, the difference from steps 72 to 75 is that DRYNO ranges from 0 to 1. It is to be changed sequentially within. DRYNO when "Dry only" course is selected
The reason why the process does not become = 2 is that when only the drying step is performed, the tableware will not be dried even if only air that is not blown by the heater is blown, so that the blowing course cannot be selected. If the drying selection switch has not been pressed, the process proceeds to step 90, where the currently selected cleaning / drying course, that is, MODNO, D
The lamp corresponding to RYNO is turned on. Step 91 is a step for judging whether or not the start / pause switch has been pressed. If the start / pause switch has been pressed, the drying step 92 is executed in the next step. Then, all lamps are turned off, and the power is turned off in step 83, and the process returns to step 63.
If the start / pause switch is not pressed in step 91, the process proceeds to step 85 and steps 85 to 85
The process at 90 is executed again.

According to the flow described above, the cleaning course lamp which is turned on when the power switch is turned on is the same as the cleaning course lamp selected by the previous cleaning selection switch.
Similarly, the drying course lamp that is turned on when the power switch is turned on turns on the drying course lamp that was selected when a cleaning course other than the “drying only” course was previously selected.

In the above, an embodiment of the present invention has been described in which, in addition to the selection switch capable of selecting a plurality of cleaning courses, a switch having a drying-only course selection switch capable of selecting "drying only" is provided. The pre-washing and rinsing of the tableware may be set as such, and the dedicated operation selection switch may be a pre-washing switch for performing only the pre-washing of the tableware or a rinsing switch for performing only the rinsing. Note that the dedicated operation course is not limited to one course, and the above-mentioned “dry only”, “pre-wash only”, and “rinse only” are prepared, and the course is selected with the dedicated operation selection switch. You may be able to.

[0024]

As described above, according to the present invention, a switch for selecting a dedicated course is provided separately from a switch for selecting a normally used course, thereby providing an easy-to-use dishwasher with little cost increase. It is possible to do.
