Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully-automatic rice cooker, which is used for restaurants and sushi restaurants.

[0002]

2. Description of the Related Art A rice-cooking unit for receiving discharged rice from the rice-washing unit and cooking rice is provided at the bottom of the rice-washing unit for washing measured rice, and the rice-washing unit opens and closes a rice-discharging port and the rice-discharging port at the bottom thereof. The rice cooker is provided with a free rice discharge valve, and the rice cooker is an outer pot on a pedestal that is movable in the lateral direction between a rice cook position located below the rice discharge port and an extract position pulled out from the rice cook position. A fully-automatic rice cooker equipped with a rice cooker in which an inner pot is removably combined is known from Japanese Patent Application Laid-Open No. 62-13020.

[0003]

In the above-mentioned prior art,
It was not possible to determine whether or not the inner pot was set in the outer pot, and there was a risk that rice would be discharged from the rice washing section despite the absence of the inner pot. In view of this, the present invention detects the set position of the gantry that allows the rice cooker to be freely put in and taken out, judges the presence or absence of the inner pot by this detection signal, and allows rice to be discharged only when the inner pot is present. It is an object to provide a device.

[0004]

According to the present invention, a rice cooking section 10 for receiving discharged rice from the rice washing section 4 to cook rice is provided below a rice washing section 4 for washing measured rice. A rice discharging port 5 and a rice discharging valve 6 for opening and closing the rice discharging port 5 are provided at the bottom, and the rice cooking unit 10 is pulled out from the rice cooking position located below the rice discharging port 5 and this rice cooking position. The outer pot 14 and the inner pot 1 are mounted on a pedestal 16 which is movable laterally between the take-out position and the take-out position.
In order to achieve the above-mentioned object in a fully-automatic rice cooker equipped with a rice cooker 15 in which 3 are detachably combined,
The following technical measures are taken.

That is, according to the present invention, a detecting means 18 for detecting the rice cooking position of the gantry 16 is provided, and a judging means 19 for deciding the presence or absence of the inner pot 13 by the detection signal of the detecting means 18 is provided. It is characterized in that means 9 for opening the rice discharge valve 6 is provided at the rice cooking position and when the inner pot 13 is set.

[0006]

Operation: The rice cooker 15 is set on the pedestal 16 and the pedestal 16 is placed so that the rice cooker 15 is located at the rice cooking position directly below the rice washing section 4.
Push in the direction of arrow A. Then, when the detection means 18 detects the rice cooking position, the determination means 19 operates to determine the presence or absence of the inner pot 13 based on the signal.

When the inner pot 13 is present, the valve opening means 9 is operated to put a predetermined amount of rice into the inner pot 13 to shift to the rice cooking process. On the other hand, when the inner pot 13 is empty, the valve opening means 9
Does not operate, the pedestal 16 is pulled out in the B direction, and the inner hook 13 is set.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 and FIG. 2, the fully-automatic rice cooker 1 comprises a rice storage hopper 2 provided at an upper portion, a rotary-type weighing cutout body 3 provided at a lower portion of the hopper 2, and a funnel-shaped rice washing tank. The rice washing part 4 is provided, and the rice discharging port 5 formed in the lower part of the rice washing part 4 is provided with a rice discharging valve 6 which can be opened and closed by vertical movement.

The rice washing section 4 is provided with a rice washing stirring means 7 and a water supply means 8 for the rice washing section 4.
The rice discharge valve 6 is provided with valve opening means 9 above the valve rod for moving the valve rod up and down by a motor, a crank or the like. A rice cooker 10 is provided below the rice discharge port 5, and the rice cooker 10 is provided with a lid 12 that moves up and down by a lid opening / closing means 11 and an inner pot 13 that can be inserted into and removed from an outer pot 13. A rice cooker 15 is provided, and the rice cooker 15 is placed on a pedestal 16 which can be pulled out in the directions A and B shown by arrows.

The lid 12 is provided with a shutter 17 which can be opened and closed at the center thereof, and an opening portion which is opened and closed by the shutter 17 is located directly below the rice discharge port 5 so that the inner pot 13 can be covered. Since the frame 16 can be pulled out in the directions A and B,
The rice cooker 15 is movable in the lateral direction (front and back) with the lid 12 left between the rice cooking position immediately below the rice discharge port 5 and the pulled-out position.

Detecting means 18 for detecting that the gantry 16 is at the rice cooking position is provided, and the judging means 19 for judging the presence or absence of the inner pot 13 by the detection signal from this detecting means 18 is operable. The detection means 18 is composed of an elastic actuator 18A, a microswitch 18B, etc.
When the outer pot 14 comes into contact with and is pushed in, the switch 18B is turned on.

The judging means 19 may be a circuit for judging the presence or absence of the inner pot 13 based on the current value when the rice cooker 15 is of the electromagnetic induction type, and it is turned on when the inner pot 13 is set.
It may be a micro switch. Further, the front side of the rice storage hopper 2 is a control unit 20 for automatically controlling each process from the start to the cooking shown in FIG. 1, and the control unit 20 and the control unit of the rice cooker 15 are connected to each other. Can perform the communication shown in FIG.

[0013] Next, the outline of the fully automatic control will be described. When starting, a series of control of weighing, washing rice, raising a colander, adding and removing water, discharging rice, soaking, cooking rice, wiping, and cooking up is performed. The detection means 18 detects whether or not the gantry 16 is at the rice cooking position (a rail set in the figure) between the strainer raising and the water addition and between the water addition and the rice removal, and the detection signals thereof. Is operated so that the presence / absence of the inner pot 13 is judged by the judging means 19, so that the water addition and the rice discharge are operated respectively.

That is, when the gantry 16 is at the rice cooking position and the inner pot 13 is set, the valve opening means 9 is operated to supply the rice with a predetermined amount of water to the inner pot 13. It is possible to cover the inner pot 13 with the lid 12 and close the shutter 17 of the lid 12 to perform the soaking step and then the rice cooking step. After the cooking process, the lid 12 is lifted and the gantry 16 is moved in the B direction, and the cooked rice in the inner pot 13 is carried to a predetermined location.

[0015]

As described in detail above, according to the present invention, the detecting means 18 for detecting the rice cooking position of the gantry 16 is provided, and the judging means 19 for judging the presence or absence of the inner pot 13 by the detection signal of the detecting means 18. Is provided, and the gantry 16 is at the rice cooking position and the inner pot 1
Since the means 9 for opening the rice discharge valve 6 at the time of setting 3 is provided, no extra alarm due to vibration such as the withdrawal operation of the gantry 16 is emitted, and rice is discharged and cooked for the first time at the regular position. It is possible to shift to the process.
