DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker used in kitchens such as restaurants, Chinese restaurants, sushi restaurants, hotels and the like.

[0002]

2. Description of the Related Art Some rice cookers include a rice washer for washing weighed rice and a plurality of rice cookers for receiving and washing rice from the rice washer. The user looks at the indicator lamps of each rice cooker to determine whether the rice cooker is cooking rice, and if there is a rice cooker that is not cooking rice, move the rice washer there by manual operation of a switch, etc. Rice was washed from the bowl and cooked.

[0003]

Therefore, in the prior art, the user has to check the rice cooker that is not cooking rice with an indicator lamp or the like and perform switch operation or the like, which is troublesome.
There was also a problem in the efficiency of rice cooking. The present invention has been made in view of the above problems, and has been made to enable efficient rice cooking without troublesome operation.

[0004]

Means for Solving the Problems The technical means of the present invention for solving this technical problem comprises a rice washer for washing the weighed rice, and a plurality of rice cookers for receiving and washing the rice from the rice washer. In rice cooker, it supports plural rice cookers
Each detection sensor detects whether it is cooking rice
A rice cooker that receives a detection signal from each of the detection sensors to determine whether or not each rice cooker is cooking rice; and a rice cooker that has determined that the rice cooker is not cooking rice. The present invention is characterized in that rice cooking control means for cooking rice and cooking the rice is provided.

[0005]

[Function] The rice cooker discriminates whether or not each rice cooker is cooking rice. The rice cooker controls the rice cooker to discharge the rice from the rice washer not being cooked to the rice cooker that is not being cooked, and sequentially cooks the rice cooker that is not cooked. Let them cook rice automatically.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 2 and 3, the apparatus main body 1 is formed in a box shape having an internal space, and a rice storage tank 2 is provided at a lower portion thereof.
Is provided, and the rice in the rice storage tank 2 can be transported to a hopper 5 with a measuring device 4 provided on the upper portion of the apparatus main body 1 by a transporting apparatus 3 provided on one side of the apparatus main body 1.

[0007] A first rice cooker 7a is provided on the lower side of the apparatus main body 1.
And the second rice cooker 7b are arranged on the gantry 8. Each of the rice cookers 7a and 7b is placed on a slide guide 9 on a gantry 8, and is detachable from the apparatus main body 1. The rice cookers 7a and 7b have an inner pot 12 removably fitted to an outer pot 11, and an inner lid 13 is openable and closable with a pin shaft 15 as a fulcrum together with an outer lid 14, and a secret state is provided by a hook or the like (not shown). Is a gas cooker that can be held in Hopper 5 with scale 4 and each rice cooker 7
A rail 16 is provided between a and 7b, and a rice washing machine 17 is movably provided on the rail 16. The rice washer 17 can be reciprocated between the rice cookers 7a and 7b on the rail 16 by driving wheels and driven wheels (not shown), and can be stopped at positions corresponding to the rice cookers 7a and 7b. Figure 1, limit switch, timer, etc.
Is connected to the motor circuit of the rice washing machine traveling motor 18 shown in FIG.

The inner pot 12 of the rice cookers 7a, 7b is shown in FIG.
And a shutter 2 at the center of the inner lid 13 as shown in FIG.
The shutter 21 is rotatably supported about a vertical axis 23, and is opened and closed by a shutter open / close motor 24 in a reciprocating rotation about the vertical axis 23. The rice washer 17 is provided with a rice washing tank 2 having a funnel section at a lower portion.
In the rice washing tank 25, there is provided a stirring member 27 rotatably driven by a stirring motor 26.
A rice discharge opening 28 at the lower end is provided with a conical valve 29 that can be opened and closed. The conical valve 29 is provided with a valve drive motor 30 shown in FIG.
Thereby, the rice discharge opening 28 is opened and closed.
Since the rice washer 17 reciprocates, a water supply hose or the like for the rice washer 17 has a moving length of the rice washer 17, and the weighing device 4 is a cut-out rotator driven by a weighing motor 32. Rice washing tank 25 via chute 31
Put metered rice into.

FIG. 1 is a block diagram of a control system. In FIG. 1, a control device 35 is for controlling the rice cookers 7a and 7b, the rice washing machine 17 and the measuring device 4, and is constituted by a microcomputer or the like. Have been. The control device 35 receives signals from a first rice cooker detection sensor 36a that detects that the first rice cooker 7a is cooking rice, a second rice cooker detection sensor 36b that detects that the second rice cooker 7b is cooking rice, and the like. , The rice washing machine running motor 18 and the shutter opening / closing motor 2
4. It outputs a control signal to the valve drive motor 30, the stirring motor 26, and the like, and has a rice cooker discriminating means 38 and a rice cooker controller 39.

[0010] The rice cooking means 38 determines whether or not each of the rice cookers 7a and 7b is cooking rice. The rice-cooking control unit 39 determines whether or not the rice-cooking determination unit 38 determines that the rice is not being cooked.
The rice is discharged from the rice washer 17 with respect to 7b to make it cooked. That is, after the rice washer 17 is moved to the rice cooker side where rice is not being cooked by the drive of the rice washer travel motor 18, the conical valve 29 is opened and closed and the shutter 21 is opened and closed by the drive of the shutter open / close motor 24 and the valve drive motor 30. ,
The rice cookers 7a and 7b are operated.

Next, the operation in the rice discharging step will be described with reference to the flowchart shown in FIG. When the rice washer 17 is on the first rice cooker 7a side, in step 1, the first rice cooker 7
It is determined whether or not a is cooking rice, and if not cooking rice, the process proceeds to step 2, and after discharging rice to the first rice cooker 7a in step 2,
In step 3, the first rice cooker 7a is operated to cook rice by gas ignition or the like. On the other hand, if the first rice cooker 7a is cooking rice, the process proceeds to step 4.

In step 4, it is determined whether or not the second rice cooker 7b is cooking rice. If not, the process proceeds to step 5,
In step 5, the rice washer 17 is moved to the second rice cooker 7b side, and in step 2, rice is discharged to the second rice cooker 7b. In step 3, the second rice cooker 7b is operated to cook rice by gas ignition or the like. On the other hand, if the second rice cooker 7b is cooking rice in step 1, the process returns to step 1.

When the rice washer 17 is located on the second rice cooker 7b side, the only difference is that the first rice cooker 7a and the second rice cooker 7b are interchanged. The same operation as in the case of the side is performed. In the above embodiment, two rice cookers 7 are provided for one rice washer 17, but three or more rice cookers 7 may be provided for one rice washer 17 instead. Good. Further, a solenoid or other driving means may be used in place of the rice washing machine traveling motor 18, the shutter opening / closing motor 24, the valve driving motor 30, and the stirring motor 26.
Alternatively, one stirring motor 26 may be shared by one motor.

In the above-described embodiment, one rice washer 17 is reciprocated with respect to two rice cookers 7, but a plurality of rice cookers 7 are reciprocated with respect to one rice washer 17 instead. It may be moved or rotated.

[0015]

According to the present invention, a plurality of rice cookers can be used.
A detection sensor to detect whether it is cooking rice.
Each provided, a rice cooker discriminating means for inputting a detection signal from each of the detection sensors to determine whether or not each rice cooker is cooking rice, and a rice cooker discriminating that the rice cooker is not cooking rice,
The rice cooker is equipped with a rice cooker control unit that discharges rice from the rice washer and cooks it. Can be automatically cooked in sequence, so that a plurality of cookers can efficiently cook rice.
