Abstract

PROBLEM TO BE SOLVED: To automatically supply rice by a compact device by fitting a cylindrical body housing a conical valve pressurized upwards by a spring and made freely vertically openable and closable to the upper lid of a rice cooker and driving the conical valve to be opened and closed by the rice discharge valve of an automatic rice washing machine. SOLUTION: An automatic rice cooker 3 provided with this automatic rice supply device 4 is arranged right below the rice washing tank 1 for a rice storage, a hollow cylindrical body 18 holding annular packing 16 is provided on the upper lid 2 and a shaft 19 to which the conical valve 12 is freely slidably attached through the spring 15 is supported and fixed to the lower part. The conical valve 12 pressurizes the annular packing 16 at the outer edge part of a circumference and tightly closes the rice cooker 3 at an upper limit position. Then, when rice washing and water adjustment are ended inside the rice washing tank 1, the rice discharge valve 6 at a tightly closing position 9 is rapidly dropped to an open position 10 through a shaft 5, the conical valve 12 at the tightly closing position 11 is pushed up by the rice discharge valve 6 and opened to the open position 13 simultaneously and the rice and rice cooking water are supplied to the inner pot of the rice cooker 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rice feeder necessary for realizing a fully automatic rice cooker for automatically processing all steps from rice storage, weighing, washing, water control, immersion, rice cooking and steaming. It concerns the device.

[0002]

2. Description of the Related Art Many proposals have been made for realizing a smaller automatic rice cooker than before. However, in reality, problems such as sales costs, external dimensions or technical difficulties, water supply and drainage, etc. have not been solved, and there has been no commercial product.

[0003]

A conventional fully automatic rice cooker for home use has a hopper-shaped rice storage at the top, a meter and a rice washing tank at the bottom, and a rice cooker at the bottom. The mainstream was configured by each. In the above configuration, the self-standing type has a large overall height of about 1 m, and the structure is extremely complicated. In addition, since it is a floor-standing type, there is a major problem in terms of manufacturing costs in addition to the difficulty of water supply and drainage.

[0004]

[Means for Solving the Problems] The present inventor has filed Japanese Patent Application No. 7-3.
The compact automatic rice cooker equipped with the automatic rice feeding device of the present invention is mounted on the small automatic rice washing device proposed in Japanese Patent No. 17610, so that all conventional problems can be solved. It is possible to provide.

[0005] The apparatus of the present invention comprises an automatic rice cooker having an upper lid in which the rice feed port of the present invention is fitted immediately below a rice discharge port provided at the bottom of a rice washing tank of a small automatic rice washing apparatus.
The rice cooker is mounted on a drawer that can be pulled out with the top lid closed, and the rice feed port is configured to be concentric with the rice discharge port when inserted into the apparatus.

Further, the apparatus of the present invention is configured so that it can be opened and closed in conjunction with a rice discharge valve that automatically opens and closes the rice discharge port of the rice washing tank arranged at the top, so that no special drive source is required. The operation can be ensured, and the configuration can be made inexpensively and compactly.

[0007]

[Operation] In FIG. 1, an automatic rice cooker (3) having an upper lid (2) hermetically sealed immediately below a rice washing tank (1) is provided. It is arranged to be coaxial with the axis of the rice washing tank. At the bottom of the rice washing tank, there is arranged a rice discharging valve (6) configured to be openable and closable up and down via a shaft (5), and has a small gap with the upper end of the cylindrical portion (7) of the rice feeding device. (8).

[0008] When the rice washing and water leveling are completed in the rice washing tank (1), the rice discharging valve (6) provided at the closed position (9) is opened by the cam mechanism (not shown) via the shaft (5). Fall rapidly to (10). At the same time, the conical valve (12) in the closed position (11) is pushed down by the rice discharging valve to open to the open position (13), and forms a flow path shown by a dotted line (14) in the figure to form an inner pot of the rice cooker. Is supplied with rice and cooking water.

When the rice discharge from the rice washing tank is completed, the rice discharge valve returns to the closed position by the cam mechanism to seal the tank. At the same time, the conical valve returns to the origin by the built-in spring (15), compresses the annular packing (16), and seals the rice feed port. With an extremely simple mechanism as described above,
It is possible to supply rice and cooking water from the rice washing tank to the rice cooker without opening and closing the top lid of the rice cooker, and it is possible to automatically start rice cooking after the immersion time has elapsed.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, the apparatus is an automatic rice cooker (3) shown in FIG.
A hollow cylindrical body (18) having an annular packing (16) at its lower end, and a bottom plate (20) suspended and fixed below the cylindrical body to support and fix a shaft (19). And a conical valve (12) slidably fitted to the shaft via a spring (15).

Since the valve body of the conical valve (12) is formed in a conical shape, the conical flow path is smoothly formed when the rice and water flow into the conical valve, and the rice is formed in the inner pot (21) in a donut shape. Can be deposited. In the upper limit position,
The rice cooker can be hermetically closed by pressing the annular packing (16) at the outer periphery of the circumference.

The outer periphery of the annular member (22) has an inner lid (2).
3) is inserted. The rice cooker (3) that can be pulled out and the rice washing device fixedly arranged on the upper part are arranged with a small gap, and are configured so that their axes coincide.

FIG. 2 shows an embodiment of a fully automatic rice cooker equipped with the automatic rice feeder of the present invention, in which a rice washing tank (1) is suspended and fixed through an inclined bottom plate portion of a rice storage (24). And
Just below the rice washing tank, an automatic rice cooker (3) having an automatic rice feeding device (4) on an upper lid (2) is mounted on a stand (25) that can be pulled out.

At the rear of the automatic rice cooker (3), a rice storage (2)
A meter (26) communicating with 4) and a suction hopper (27) for milled rice are provided respectively. In addition, a blower (28) for conveying the milled rice, which communicates with the rice washing tank, is provided at the upper rear of the rice storage (24).

[0015]

Since the apparatus of the present invention is constructed as described above, an automatic rice cooker provided with the rice feeding apparatus according to the present invention is disposed directly under the automatic rice washing apparatus so as to be able to be drawn out, and the whole can be extremely easily constructed. An automatic rice cooker can be realized.

An automatic rice cooker provided with the apparatus of the present invention;
By combining with the small automatic rice washing device proposed in Japanese Patent Application No. 7-317610, it is possible to realize a compact and inexpensive fully automatic rice cooking device having a total height of about 1/2 as compared with the conventionally proposed device.

A fully automatic rice cooker equipped with the apparatus of the present invention comprises:
Water supply and drainage, which has been considered a problem since it can be used in a kitchen as a tabletop type, is a revolutionary invention that has many advantages such as the ability to use the sink as it is and has high industrial utility value. It is.
