Abstract

PROBLEM TO BE SOLVED: To prevent the erroneous operation of another worker by reporting a reserved state when work conditions are reserved and different conditions are inputted later concerning an automatic rice cooker with which every work of measuring/rice washing/rice cooking is executed at the time set in advance. SOLUTION: When operating the automatic rice cooker provided with a rice storage, washer and rice cooker, the quantity of rice to be boiled, water level and the degree of washing or the like are set by operating switches for work conditions. Next, the reserved time is set by a switch 6a for reservation. Then, an under-reservation indicator 7c is turned on, the state of 'under reservation' is displayed and the reserved time is displayed on a display 7b. At this reserved time, when the other worker inputs the rice cooking quantity switch of the switch for work condition by mistake, a microcomputer detects abnormality and sounds an alarm buzzer 14 and it is reported that the current conditions are reserved. The worker, who listens to this abnormality report, grasps the state under reservation and resets the original conditions.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice cooker for weighing, washing, and cooking rice.

[0002]

2. Description of the Related Art It is very convenient to automatically carry out work from weighing rice to cooking rice, for example, at a restaurant, by setting (reserving) when to cook in the morning of the next day to improve work efficiency. is there.

[0003]

[Problems to be Solved by the Invention] However, even if a reservation is made, if another worker inadvertently touches the operation switch or leaves the rice cooker in the pulled-out state, the reservation does not work, It may not be possible to cook rice at a specified time.

[0004]

The present invention provides an automatic rice cooker for preventing erroneous work, and has taken the following technical means. That is, in an automatic rice cooker that performs each work of weighing, washing rice, and cooking rice at a preset time, if a different condition is input after a work condition is reserved, a notification means for notifying that the reservation is made is provided. An abnormality notification device for an automatic rice cooker.

[0005]

Operation: The operator operates various switches to make a reservation.
Then, at a predetermined time before the reserved time, the work of weighing and washing rice is performed, and when the reserved time is reached thereafter, the rice cooking is completed. If another worker inadvertently operates the switch or the drawer of the rice cooker at the time of reservation, the notification means informs the worker that the reservation is being made. Can immediately know that he made a mistake.

[0006]

[Effect] Even during the reservation, the worker can know that it is necessary to perform the correction work for the original reservation, which is the next work, and it is possible to prevent the problem that the cooked rice cannot be made at the time of reservation.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. First, the structure will be described. The automatic rice cooker 1 is provided with a rice storage 3, a washer 4, and a rice cooker 5 in that order from the upper side to the lower side of the frame 2. The rice storage 3 is provided with an operation panel 8 including various switches 6 and a display 7 on the front wall in a detachable manner, and a hopper weighing roll (not shown) for storing rice. ing. The switch 6 includes a switch for work conditions such as the amount of rice cooked, a reservation switch 6a for setting a reservation time (month, day, time), and the display tool 7 is a work status display tool 7a for displaying the work status. There are a display tool 7b for displaying a reservation time, a reservation display tool 7C for indicating that a reservation is in progress, and the like. 14 is a notification buzzer.

The washer 4 is provided with a tank 4a for storing rice supplied from the metering roll and water sent through a water supply nozzle, an agitator, an elevating valve and the like. The rice cooker 5 is provided with an inner pot 9, an outer pot 10, a lid 11, a shutter 12 for opening and closing a charging opening formed in the central portion of the lid 11 by the raising / lowering action of the raising / lowering valve. I have it. The shutter 12 is opened / closed by a shutter opening / closing arm 13 operated by a drive motor (not shown).

Although not shown, each device and apparatus is controlled by a microcomputer. Next, its operation will be described. A switch for working conditions is operated to set the amount of cooked rice, water addition (hardness), cleaning degree, and the like. Then, when the input of the work condition is completed, the reservation time is set by the reservation switch 6a. Then, the in-reservation display tool 7c lights up to indicate "reservation in progress" and the reserved time is displayed on the display tool 7b.

At the time of this reservation, if another worker inadvertently inputs the rice cooking amount switch, which is a switch for working conditions, the microcomputer detects an abnormality and informs the buzzer 14 that the present condition is under reservation. Yes Abnormality is notified. Then, the worker who hears this abnormality notification can grasp that the reservation is in progress and reset the original condition.
In particular, when the rice cooking time is operated, it is possible to prevent problems such as rice not being cooked at the originally set time by resetting the reserved time.

If there is no erroneous operation, the computer outputs a work command signal by a pre-installed program when a predetermined time elapses before the completion of rice cooking.
Therefore, the weighing roll rotates to move rice from the hopper to the tank 4
When the amount of rice cooked reaches a predetermined value (number of rotations), the rotation is stopped. Subsequently, the rice is washed with the rotating stirring body and the water supplied by the water supply means. When the washing is completed, the lift valve descends to drop rice and water for cooking rice from the tank 4a, and stores the rice and rice in the inner pot 9 through the inlet of the lid 11 of the rice cooker 5. After that, since the drive motor is driven to operate the shutter opening / closing arm 13, the shutter 12 is also moved in connection with this to close the insertion opening.

Then, after a predetermined time (immediately when the immersion is completed), the ignition switch is turned on to ignite the gas and start the rice cooking operation. After the rice is cooked, the rice is cooked at the preset reservation time.
