The lower frame 48 may be detachably provided as described above, or may be provided below the frame 5.

The block circuit of FIG. 9 will be described.
Reference numeral 37 performs arithmetic, logical and comparison operations. Among the various types of information input to the CPU 37 through the input interface 50, the main information includes the amount of rice cooked,
Washing method, soaking time, spotting time, one pot / summary / continuous,
Rice cooking information from each switch for setting the ignition (manual / automatic), power on / off information from the power switch 16, vertical position information of the rice storing section A from the limit switches 29 and 30,
Temporary stop information from the temporary stop switch 3, rice cooker withdrawal information from the limit switch 49, start switch 3
6 and the rice storage section elevating information from the elevating switch 53.

Among various kinds of information output from the CPU 37 through the output interface 51, the main information includes a drive command signal to the motors 14, 21, 25, 38 and a drive command signal to the solenoid valve. There are an opening / closing command signal, a drive command signal to the solenoid 44, and a lighting notification command signal to a notification lamp (may be sound notification, alarm sound notification, etc.) 52 provided on the operation panel 35.

Next, the operation will be described. First, when setting the working conditions, the power switch 16 is turned on to energize, and various switches such as a rice cooker switch of a switch section provided on the operation panel 35 are operated. When the amount of cooked rice, the amount of water added, how to wash, how to immerse, the time for washing, the mode of cooking rice in one pot / summary / continuous rice are set, the selected working conditions are taken into the CPU 37 via the input interface 50. .

After completing the preparations for the operation, the start switch 36
Is entered, the CPU 37 executes the control program flow.
First, a forward rotation drive command signal is output to the forward / reverse rotation motor 25 via the output interface 51. As a result, the motor shaft 24 rotates forward and moves up the screwed moving body 28.
Rice cooker A and washer B provided integrally with moving body 28
Also rises. At this time, the rollers 32 and 33 are frame 5
, The case 9 is prevented from swinging in the front-rear direction and can be lowered smoothly.

When the moving body reaches the predetermined position and turns on the limit switch 29, the CPU 37 stops outputting the drive command signal to the forward / reverse rotation motor 25.
The lifting action of the rice storing section A and the washing section B is stopped at a predetermined position. The CPU 37 outputs a drive command signal to the motor 14 via the output interface 51 to start the motor when the rice storing section A is at the uppermost position or when the rice storing section A rises. Then, the rice stored in the funnel 10 of the rice storage unit A is supplied in a fixed amount.

Therefore, there is no need to turn on the start switch 25 after the rice storage section A is moved to the predetermined position by driving the forward / reverse rotation motor 25 forward by the on operation of the elevation switch 53. In addition, the waiting time can be shortened and the working efficiency can be increased. Further, when the rice storing section A and the washing section B are integrally moved up, the work can be started from the rice supply, so that the working efficiency can be further improved.

Next, an "open" signal is output to the solenoid valve and the motor 21 is started, so that the water sent from the water supply source passes through the water supply pipe 11 and the check valve and enters the washing tank. The water is sprinkled and the stirring shaft 22 and the stirring body 23 rotate to stir and wash the water and rice. Further, since the CPU 37 outputs an excitation signal to the solenoid 44 via the output interface 51, the operating mechanism 45 operates the drain opening / closing valve 46 to open the drain 43.

At this time, the generated sewage enters the drain box 37 from the washing tank 12 through the jacket 18 and the drain port 43, and is then discharged outside the machine through the drain pipe 47. When cleaning is completed, the solenoid valve closes and the
Since the driving of the heater 14 is stopped, the water supply and the stirring are stopped.

When the sewage in the washing tank 12 is drained (controlled by time), the solenoid valve is opened, and the drain opening / closing valve 46 is moved by the excited solenoid 44 to move the drain 43
Is closed, the supplied water is supplied from the water supply pipe 11 through the check valve and supplied to and stored in the cleaning tank. Then, at a predetermined time, the solenoid valve is closed, the water supply operation is completed, and the water is adjusted.

Next, after the immersion time, the motor 38 is driven to lower the valve shaft 39 and the drop valve 20 to open the rice discharge port 19. Then, the rice and water in the washing tank 12 fall and are accommodated in the inner pot of the rice cooker 1 below, and then automatically ignited by the ignition signal output from the CPU 37, and cooked. .

In the rice cooking operation, the rice storing section A
In some cases, the funnel 10 is replenished with rice, and at this time, the elevating switch 53 is set to the descending side. Then
The CPU 37 which has received the descending signal via the input interface 51 outputs a reverse rotation command signal to the forward / reverse point motor 25 via the output interface 51. As a result, the motor shaft 24 rotates in the reverse direction to move down the screwed moving body 28. In connection with this, the rice cooker A and the washing section B provided integrally with the moving body 28 also move down. . At this time, the rollers 32 and 33 slide while rotating while holding the frame 5, so that the case 9 can be prevented from swinging in the front-rear direction and can be lowered smoothly.

When the movable body reaches the predetermined position and turns on the limit switch 30, the CPU 37 stops outputting the drive command signal to the forward / reverse rotation motor 25.
The lowering operation of the rice storing section A and the washing section B is stopped at a predetermined position. When lowering the rice storage unit A, if the stopper 2a is below the stopper receiving body 9a, the stopper 2a does not lower, so that the rice cooker 2 needs to be pulled forward to a predetermined position. Washing tank 12 by contact of
The rice cooker 1 can be prevented from being damaged.

When the up / down switch 53 is set to the up side, the CPU 37, which has input the up signal via the input interface 51, instructs the forward / reverse point motor 25 via the output interface 51 to perform forward rotation. Output a signal. Thus, the motor shaft 24 is rotated forward and screwed into the moving body 28.
In this connection, the rice cooking section A and the washing section B provided integrally with the moving body 28 also rise. At this time, the rollers 32 and 33 slide while rotating while holding the frame 5, so that the case 9 can be prevented from swinging in the front-rear direction and can be lowered smoothly.

When the mobile body reaches the predetermined position and turns on the limit switch 29, the CPU 37 stops outputting the drive command signal to the forward / reverse rotation motor 25.
The lifting action of the rice storing section A and the washing section B is stopped at a predetermined position. Since the lifting switch 53 cannot be operated to lower the rice storage unit A or the like unless the rice cooker 2 is pulled out to a predetermined position, the washing tank 12 and the rice cooker 1 are brought into contact with the washing tank 12 and the rice cooker 1. Damage can be prevented.
Further, by providing the lower frame 48, the entering operation can be performed using a foot, so that the operator can perform another operation with his / her hand, thereby improving convenience.

When the temporary stop switch 3 is turned on, the CPU 37 which has received the temporary stop information via the input interface 50 outputs a stop command signal to the forward / reverse rotation motor 25 via the output interface 51. Therefore, the raising or lowering of the rice storing unit A and the washing unit B is temporarily stopped. Therefore, the rice storage unit A and the washing unit B can be stopped urgently, and convenience can be improved.

When the pause switch 3 is turned on, the CPU 37 outputs a forward (reverse) command signal to the forward / reverse motor 25 via the output interface 51.
Since the rising (falling) of the rice storing section A and the washing section B is started, the operability can be improved. At the time of raising / lowering by operating the temporary stop switch 34, if there is an input of another switch, for example, the vertical switch 53, the temporary stop by the input of the temporary stop switch 3 is reset, so that workability is good.

When the rice cooker 2 is pulled out, the limit switch 49 does not turn on until the rice cooker 2 reaches the set position. In this state, the CPU 37 does not input the lowering even if the raising / lowering switch 53 is turned down. Forward / reverse motor 2
5 is not output. Therefore, it is possible to prevent damage caused by collision between the washing tank 12 and the rice cooker 1.
