As described above, the cleaning display setting unit 85 can individually set the number of operations at a plurality of cleaning locations.
The cleaning display command unit 86 corresponds to the number of operations when the actual number of operations (actual number of operations) in the rice washing device 3 (rice cooker 1) matches the number of operations set by the cleaning display setting unit 85. A cleaning indication is given to the cleaning portion.
For example, as shown in FIG. 4A, the number of operations actually performed after setting the number of operations of the rice washing tank 20 is counted, and the number of actual operations is set in the cleaning display setting unit 85. When the number of operations (70 times) is reached, the cleaning display command unit 86 displays on the display unit 70 that the time for cleaning the rice washing tank 20 has come. Also, as shown in FIG. 4 (c), when the number of operations actually performed after setting the number of drain hose operations is counted, and the number of actual operations reaches the number of drain hose operations (100 times). The cleaning display command unit 86 displays on the display unit 70 that it is time to clean the drainage hose. In this way, when the number of operations determined corresponding to each cleaning location reaches the actual number of operations, a display prompting cleaning is displayed for each cleaning location. In addition, the cleaning display by the cleaning display command unit 86 is, for example, when the rice cooker 1 is turned on or when the number of operations determined corresponding to each cleaning portion becomes the actual number of operations and the operation ends (next) Before starting operation).

The 1st reset part 87 resets the actual driving | running number counted corresponding to each cleaning location to zero, respectively. That is, when the actual number of operations matches the number of operations set by the cleaning display setting unit 85, the cleaning display for the cleaning portion is performed. When this cleaning display is performed, the first reset unit 87, for example, When the cancel key 75 is pressed, the actual number of operations for the cleaning portion indicated by the cleaning is set to zero.
The operation permission unit 89 permits the operation when the actual operation number is reset by the first reset unit 87. For example, when the cancel key 75 is pressed in a state where the cleaning display is displayed on the display unit 70, the actual operation number is reset to zero, but the operation permission unit 89 permits the operation after this reset is performed.

FIG. 8 shows the operation of the control unit 16 in the cleaning display.
In the following description, it is assumed that the number of operations for displaying the cleaning is set for each cleaning location, and the actual number of operations is counted from the time when the number of operations is set for each cleaning location.
First, the control unit 16 determines whether or not there is a cleaning part where the actual operation number has reached the number of operations in each cleaning part set by the cleaning display command part 86 (S1). When there is a cleaning location where the actual number of operations reaches the number of operations in each cleaning location, a cleaning display for prompting the cleaning display is performed for the cleaning location that has reached the number of operations by the cleaning display command unit 86 after the operation ends (S2). For example, when the number of actual operations of the rice washing tank 20 reaches 70, when the operation is completed, the display unit 70 displays that the cleaning time of the rice washing tank 20 has come. At this time, the operation permission unit 89 accepts the input of the cancel key 75, but does not accept the input for the other keys. Unless the cancel key 75 is pressed, the processing of the display unit 70 or the processing of the rice washing device 3 is performed. Do not advance.

  It is determined whether or not the cancel key 75 is pressed in a state where the cleaning display is performed on the display portion 70 (S3). If the cancel key 75 is not pressed, the process enters a standby state. If the cancel key 75 is pressed (S3, Yes), the process proceeds to the next process. When the cancel key 75 is pressed, the actual number of operations corresponding to the cleaning location where the cleaning display has been performed by the first reset unit 87 is made zero (S4). For example, when the cleaning display of the rice washing tank 20 is performed, and the actual number of operations of the rice washing tank 20 at the time of processing S2 is 70, it corresponds to the rice washing tank 20 when the cancel key 75 is pressed. The actual number of operations is 0.

Next, it is determined whether there is any other cleaning location where the actual operation number has reached the preset number of operations other than the above-described cleaning location (1 cleaning location) (S5). When there is no other cleaning part where the actual operation number reaches the preset operation number (S5, No), the display of the display unit 70 is changed to the menu set screen B or the initial screen A, and the operation is permitted by the operation permission unit 89. Allow (S6).
If there is another cleaning location where the actual number of operations has reached the preset number of operations (S5, Yes), the cleaning indication command unit 86 will clean the other cleaning locations that have reached the number of operations following the previous cleaning display. Display is performed (S7). For example, when the actual operation number of the drainage hose is 70 times, the cleaning indication of the drainage hose is displayed on the display unit 70 after the cleaning indication of the rice washing tank 20 is turned off. As in the case of the rice washing tank 20, the operation permission unit 89 accepts input of the cancel key 75, but does not accept input for the other keys. Unless the cancel key 75 is pressed, processing of the display unit 70 or The processing of the rice washing apparatus 3 is prevented from proceeding.

  It is determined whether or not the cancel key 75 has been pressed in a state where a cleaning display at another cleaning location is being performed on the display unit 70 (S8). If the cancel key 75 is not pressed, a standby state is entered. If the cancel key 75 is pressed (S8, Yes), the process proceeds to the next process. When the cancel key 75 is pressed, the actual number of operations corresponding to the other cleaning places where the cleaning display has been performed by the first reset unit 87 is made zero (S9). For example, if the drain hose cleaning display is performed and the actual number of drain hose operations at the time of processing S5 is 70, the actual number of operations corresponding to the drain hose when the cancel key 75 is pressed. Is 0 times.

Next, it is determined whether there is another cleaning location where the actual operation number has reached the preset operation number (S10). When there is no other cleaning portion where the actual operation number reaches the preset number of operations (S10, No), the display of the display unit 70 is set to the menu set screen B or the initial screen A, and the operation is permitted by the operation permission unit 89. Allow (S11). If there is another cleaning location where the actual operation number has reached the preset number of operations (S11, Yes), a cleaning display for the cleaning location that is determined to have a cleaning location in the process is performed in S7.
FIG. 9 shows a modification of the control unit 16 in the cleaning display.

  The control unit 16 in FIG. 9 includes a second reset unit 88. The second reset unit 88 has a predetermined difference between the displayed number of actual operations at one cleaning location and the actual number of operations at another cleaning location different from the one cleaning location at the time when the cleaning indication is made. When the value is equal to or less than the value (for example, 5 times), the actual operation number corresponding to another cleaning location is also reset to zero. For example, it is assumed that the actual operation number in the rice washing tank 20 is 70 times and the actual operation number in the drainage jacket 13 is 75 times. Here, when the number of actual operations of the rice washing tank 20 becomes 70 and the cleaning indication of the rice washing tank 20 is made, a predetermined value (5) that is different from the actual number of operations of the rice washing tank 20 (70 times) is defined in advance. The actual number of operations of the drainage jacket 13 is set to zero by the second reset unit 88.

  In this embodiment, as described above, the rice washing tank 20 cannot be removed unless the drainage jacket 13 is removed, and the drainage jacket 13 is inevitably cleaned when the rice washing tank 20 is cleaned. Therefore, the second reset unit 88 has one (one) cleaning part (for example, the rice washing tank 20) and the other (the other) cleaning part (for example, a drain jacket) when there are cleaning parts to be simultaneously cleaned in this way. When the number of actual operations with 13) is equal to or less than a predetermined value, the number of actual operations of both is zero. When the difference between the actual number of operations at one cleaning location and the actual number of operations at other cleaning locations is equal to or less than a predetermined value, the second reset unit 88 also calculates the actual number of operations corresponding to other cleaning locations. Although it is reset to zero, it is preferable that one cleaning spot and the other cleaning spot have a relationship of being removed at the same time as cleaning like the relation between the rice washing tank 20 and the drainage jacket 13, It is preferable that the second reset unit 88 resets the actual number of operations to zero with respect to other cleaning portions when it is inevitably removed simultaneously when cleaning one cleaning portion.

FIG. 10 shows the operation of the control unit 16 in the modified example.
First, the control unit 16 determines whether or not there is a cleaning part where the actual operation number has reached the number of operations in each cleaning part set by the cleaning display command part 86 (S20). If there is a cleaning location where the actual operation number has reached the number of operations in each cleaning location, the cleaning display command unit 86 performs a cleaning display for prompting the cleaning display for the cleaning location that has reached the number of operations after the end of the operation (S21).
It is determined whether or not the cancel key 75 is pressed in a state where the cleaning display is being performed on the display portion 70 (S22). If the cancel key 75 is not pressed, the standby state is entered. If the cancel key 75 is pressed (S22, Yes), the process proceeds to the next process.

  Next, when the cleaning display is performed by the cleaning display command unit 86, the difference between the actual number of operations already displayed at the cleaning location and the actual number of operations at another cleaning location different from the cleaning location is equal to or less than a predetermined value. It is determined whether or not there is something that is (S23). If there is no difference between the actual operation number at the already displayed cleaning point and the actual operation number at the other cleaning point (S23, No), the actual operation number at the already displayed cleaning point is first reset. It is made zero by the part 87 (S24). Here, it is preferable that one cleaning location for resetting and another cleaning location have a relationship such as removal at the same time during cleaning.

  When there is a difference between the actual operation number at the already displayed cleaning location and the actual operation number at another cleaning location or less (S23, No), the actual operation number at the already displayed cleaning location and other Both the actual number of operations at the cleaning point (the actual number of other cleaning points related to the already displayed cleaning point) are set to zero by the first reset unit 87 and the second reset unit 88 (S25). For example, in S25, when the already displayed cleaning location is the rice washing tank 20 or the drainage jacket 13, and the actual operation number of both is equal to or less than a predetermined value, the actual operation number of the rice washing tank 20 and the drainage jacket 13 are displayed. It is made zero by the second reset unit 88 with the actual operation number.

When the second reset unit 88 resets the actual number of operations in other cleaning locations to zero, the display of the cleaning portion for other cleaning locations to be reset on the display unit 70 under the control of the control unit 16 is performed. preferable.
In addition to the already displayed cleaning location (1 cleaning location), it is determined whether there is another cleaning location where the actual operation number has reached the preset number of operations (S26). When there is no other cleaning portion where the actual number of operations reaches the preset number of operations (S26, No), the display of the display unit 70 is changed to the menu set screen B or the initial screen A, and the operation is permitted by the operation permission unit 89. Allow (S27).

If there is another cleaning location where the actual number of operations has reached the preset number of operations (S26, Yes), the cleaning indication command unit 86 cleans the other cleaning locations that have reached the number of operations following the previous cleaning display. Display is performed (S28). It is determined whether or not the cancel key 75 has been pressed in a state where a cleaning display at another cleaning location is being performed on the display unit 70 (S29). If the cancel key 75 is not pressed, the standby state is entered. If the cancel key 75 is pressed (S29, Yes), the process proceeds to the next process.
It is determined whether or not there is a difference between the actual number of operations at the cleaning location already displayed in S28 and the actual number of operations at another cleaning location different from the cleaning location that is equal to or less than a predetermined value (S30). When there is no difference between the actual operation number at the cleaning location already displayed in S28 and the actual operation number at the other cleaning location below a predetermined value (S30, No), the actual operation number at the cleaning location already displayed in S28. Is made zero by the first reset unit 87 (S31).

If there is a difference between the actual operation number at the cleaning location already displayed at S28 and the actual operation number at other cleaning locations below a predetermined value (S30, No), the actual operation at the cleaning location already displayed at S28 will be described. Both the number of operations and the actual number of operations at other cleaning locations are made zero by the first reset unit 87 and the second reset unit 88 (S32).
In addition to the cleaning locations already displayed in S21 and S28, it is determined whether there are other cleaning locations where the actual operation number has reached the preset number of operations (S33). When there is no other cleaning portion where the actual number of operations reaches the preset number of operations (S33, No), the display of the display unit 70 is changed to the menu set screen B or the initial screen A, and the operation is permitted by the operation permission unit 89. Allow (S34).

  According to the present invention, the cleaning display setting unit 85 that sets the number of operations for performing a cleaning display that prompts cleaning for each cleaning location, and the actual number of operations set to the number of operations set by the cleaning display setting unit 85. And a cleaning display command unit 86 for performing a cleaning display on the cleaning portion corresponding to the number of times of operation. Thereby, according to the frequency | count of driving | operation of the rice-washing apparatus 3, the location which needs cleaning can be automatically notified, and it can prevent forgetting cleaning of the cleaning location. And since the frequency | count of a driving | operation for performing a cleaning display in a some cleaning location is decided separately, the cleaning display according to the dirt condition of each cleaning location can be performed.

A first reset unit 87 that resets the actual number of operations counted corresponding to each cleaning location to zero, and an operation permission unit 89 that permits operation when the actual number of operations is reset by the first reset unit 87; It has. Accordingly, since the operation cannot be started unless the actual operation number is reset, the cleaning display of the cleaning portion can be surely confirmed at the time of the reset operation.
The difference between the number of actual operations at one cleaning location and the number of actual operations corresponding to other cleaning locations for other cleaning locations different from the one cleaning location at the time when the cleaning indication is given by the cleaning display command unit 86 When it is less than or equal to the predetermined value, a second reset unit 88 is provided that resets the actual operation number corresponding to another cleaning location to zero. One (one) cleaning location is the rice washing tank 20, and the other (other) cleaning location is set in the drainage jacket 13. Thus, if the drainage jacket 13 is not removed, the rice washing tank 20 cannot be removed, and the drainage jacket 13 is necessarily cleaned when the rice washing tank 20 is cleaned. When the actual operation number of the tank 20 and the drainage jacket 13 is equal to or less than a predetermined value, the continuous cleaning display can be omitted by setting the actual operation number of both to zero. For example, if the actual operation number of the rice washing tank 20 is 70 times and the actual operation number of the drainage jacket 13 is 71 times, if there is no second reset unit 88, in the next operation of the cleaning display of the rice washing tank 20, Although the cleaning display of the drainage jacket 13 will be performed and the cleaning display may be performed even though the drainage jacket 13 has been cleaned, such a situation can be prevented by the second reset unit.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
