Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for keeping warm rice.

[0002]

2. Description of the Related Art In a conventional warm rice cooker, a heat-retaining storage box is loaded into the kitchen from the outside and placed on the rice descent path of the box with the rice cooker, and the bottom of the storage box is opened to pass through the descent path. Since the capacity was measured with a container, smooth measurement was difficult, and there was a defect that uneven measurement was caused.

In addition, due to the difference from the outside temperature during transportation, water droplets are generated especially on the lower surface of the closing lid at the upper end opening, which affects the quality of the stored rice. Also, it took a lot of effort to wash the rice attached to the inner wall of the warm storage container.

[0004]

[0006]

In the present invention, the bottom plate 6 "of the heat retaining container 6 is closed,
After opening the heat-retaining lid 6'and accommodating the rice 13 in the hopper 8, the lid 6'is closed and transported from the rice cooking factory to the kitchen, and the rice descent of the rice cooker box 1 arranged in the kitchen. The bottom plate 6 ″ of the storage box 6 is brought into contact with the upper opening of the passage 2 and the storage box 6 is placed on the machine box 1.

In this state, the bottom plate 6 "is pulled in the horizontal direction to open the bottom as shown in the solid line position in FIG. 1 or the phantom line position in FIG. 5, and the rotating blades 4 and 4'for lowering the rice are rotated to open and close the shutter 3. 1 or 7 is opened from the solid line position to the imaginary line position, the warm rice 13 in the hopper 8 descends through the descending passage 2 and is supplied onto the carry-out conveyor 10.

By rotating the carry-out conveyor 10 in the direction of arrow a, the warm rice 13 on the conveyor 10 is supplied into the container 14 on the mounting table 11. Then, the weight of the supplied rice is measured by the weight electronic measuring instrument 5 ', and the control device 1
The measurement signal b is sent to 2.

Then, the measured value is compared with a set value set in the control device 12, and when the set value is reached, the control signal c
Is emitted to operate the driving device 15a of the shutter 3 to close the shutter 3, and the residual rice 13 'on the conveyor 10 is accommodated in the container 14 by the rotation of the conveyor 10 and is fixed in the container 14. It holds a large amount of rice. Since the amount of the residual rice 13 'is almost constant, this is calculated in advance and the set value is determined.

When the storage case 6 becomes empty, the storage case 6 is separated from the machine box 1 and returned to the rice cooking factory, the lid 6'is removed, and the storage hopper 8 is separated from the storage case 6 and washed. .

In the rice cooking factory, the bottom plate 6 "is closed, water and rice are supplied into the pan 6, the lid 6'is closed to cook rice, and after the rice is cooked, it is conveyed to the kitchen as a rice cooker 9 and the bottom plate 6" is opened. Then, the arrangement can be performed as described above.

EXAMPLE The inner wall surface 7 of the heat retaining container 6 filled with the heat retaining material 15 is formed in a funnel shape, and the heat retaining rice accommodating hopper 8 can be detachably attached through the gap t formed by the projections 7 ', 7'. To support.

A gear chamber 18 for accommodating a hollow external gear 16 and a small gear 17 meshing with the hollow external gear 16 is provided in the lower part of the storage case 6, and an inflow / outflow chamber 19 for the openable / closable bottom plate 6 "is provided under the gear chamber 18. The bottom support plate 20 is provided, and the center opening of the support plate 20 is aligned with the upper end opening of the rice descending passage 2 of the rice cooker-equipped machine box 1 so that the storage bin 6 is fixed on the machine box 1. It is placed on and self-holding its position.

The upper end opening of the passage 2 is formed by the hollow portion of the lower hollow external gear 16 ', and the small gear 17' meshing with the external gear 16 'and the small gear 17 in the gear chamber 18 are removable. Are fixedly connected in the rotational direction by the common shaft 21 of the above, and the upper and lower hollow external gears 16, 16 'have the same number of teeth, and the upper and lower small gears 17, 17' also have the same number of teeth. is there.

The lower external hollow gear 16 '(on the side of the machine box 1)
A rotating blade 4 for descending the rice is provided on the inner periphery of the above, and a stirring blade 22 inside the hopper 8 is provided on the inner periphery of the hollow outer gear 16 on the upper side (on the side of the gear chamber 18).

The opening / closing shutter 3 is slidably arranged in contact with the lower surface of the lower hollow external gear 16 ', and the driving device 15a of the shutter 3 is formed by a crank 15 "provided on the output shaft of the half-rotation motor 15'. , The hollow outer gear 16 ″ is supported in contact with the lower surface of the shutter 3 and the hollow portion forms the lower part of the rice descending passage 2, and the inner periphery of the outer gear 16 ″ is for descending the rice by the stirring blade shown in FIG. A rotary blade 4'is provided, and a small gear 17 "that meshes with the external gear 16" is provided.

A rice carry-out conveyor 10 is provided just below the rice descending passage 2, a belt is rotated in the direction of arrow a by a drive motor 23, and a table 11 for placing a rice bowl 14 such as a bowl is provided just below the end of the conveyor 10. Is provided, and the platform 11 is supported by a weight electronic measuring instrument 5 ′ such as a load cell. The measuring signal b from the measuring instrument 5 ′ is sent to the control device 12 and compared with the weight set value set in the control device 12. The counter rotation motor 15 'of the shutter 3 is operated by the calculation and the signal c thereof is operated, whereby the shutter 3 can be closed from the phantom line position in FIG. 1 to the solid line position.

At the time when the shutter 3 is closed, the residual rice 13 'on the conveyor 10 is conveyed in the direction of arrow a by the conveyor 10 and is stored in the container 14.
After that, when the container 14 is gripped and unloaded from the mounting table 11, the electronic measuring instrument 5'detects this, the control device 12 is operated by the signal b, and the drive motor 23 of the conveyor 10 by the signal c '. Is to stop.

The upper end opening of the heat retaining container 6 is a heat retaining material 15.
It is formed so that it can be opened and closed by a heat-retaining lid 6'with a built-in
As a result, there is no difference between the inside temperature and the outside temperature, and the agglomeration of water drops on the lower surface of the lid 6'is eliminated.
