Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rice washing and feeding device in a rice cooking device.

・ □Conventional rice cookers have a surface water outlet at the top of the wide cone-shaped rice washing chamber, and a vertical rising pipe that is open from top to bottom, keeping a gap with the lower inner wall surface at the center of the inside. A water supply injection pipe having an upward opening was provided at the lower end of the rice washing chamber below the vertical riser pipe.

Immediately above the vertical riser pipe, a bowl-shaped reversing member with a diameter larger than the discharge pipe and wider downwardly, and a discharge pipe through which the rice water mixture is forcibly discharged, were arranged with a space therebetween.

When washing rice, water is supplied upward from the water supply injection pipe through the vertical rising pipe, and is reflected radially downward by the reversing member, causing the rice to flow together with the water and washing the rice.

When taking out the rice water mixture after washing the rice, a discharge pipe was installed instead of the above-mentioned reversing member, and the structure was such that the rice water mixture was supplied to the wooden colander through the transport pipe.

Therefore, with this device, the rice washer and wooden tray are installed separately from the colander, requiring a large space, and a separate drainage device must be installed near the rice washer, and an appropriate amount of water must be poured into the rice cooker. It was necessary to provide a separate device for feeding.

As a result, the area occupied by the device was large, and rice and water were scattered around the rice washer, making it unhygienic and wasting rice.

The present invention solves the above-mentioned drawbacks and is a rice cooking device that can wash rice, drain water, and supply water in one compact device.

An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, the rice washing chamber 1 has a cylindrical body with an open top, the lower part of which is shaped like a wide cone, and an overflow surface discharge port 1b is provided at the upper part of the peripheral wall 1a.

The lower part of the rice washing chamber 1 is connected to the rice cooking section BVc via a water supply and drainage connection section 6, a washed rice input gate valve mechanism TO, and a washed rice supply pipe 9 hanging vertically.

In the rice cooking section BVc, the pot lid B2 is connected to the pot body B1.
It can be opened and closed so that it can be raised and lowered.

A washed rice supply pipe 9 is flexibly inserted into the lid B2 and connected to the lid B2 in a tongue-tight manner via a seal packing 91.

A cylindrical vertical rising pipe 2 is installed in the center of the rice washing chamber 1.
It is fixed with a support member 2a with a predetermined gap between it and the lower inner wall surface.

A water supply pipe 3 penetrating the side wall 1a opens upwardly at the bottom of the vertical riser pipe 2 to form an injection pipe 3a.

4. is the vinegar water supply valve. □ A downward bowl-shaped reversing member 5 is set directly above the vertical rising pipe 2 with a gap therebetween via a mounting member 5a.

Water supply and drainage connection part 6 connected to the lower part of the lower wire diameter of the rice washing room 1
As shown in FIGS. 2 and 3, this is an annular block body having a rice washing through hole 6a having the same diameter as the inside diameter of the reduced diameter portion of the rice washing chamber in the center thereof.

An internal water supply/drainage port 6b is formed in an annular manner around the inside of the rice washing through hole 6a and is communicated with a water supply/drainage pipe 10 described later.

The rice washing through hole 6a and the internal water supply/drainage port 6b are separated by a filter 6c that prevents rice from passing through.

A rice washing input gate valve box 7 is connected to the lower part of the water supply and drainage connection part 6.

That is, the rice washing input gate valve box 7 has a rectangular thick plate shape, and includes a valve box upper part 71 integrally formed on the lower surface of the water supply/drainage connection part 6, and a rectangular thick plate shaped valve box integrally formed with the valve box upper part 11. lower part 7
2 and more.

The upper part 71 of the valve box has a valve inlet hole of the same diameter that communicates with the rice washing through hole 6a. , a is drilled.

Further, a valve outlet hole 7b concentric with the valve inlet hole γa is bored in the lower part 72 of the valve box, and a washed rice supply pipe 9 having an inner diameter approximately the same as that of the valve inlet hole 7a is fitted and welded into the extraction hole 7b. Ru.

Between the upper part 71 of the valve box and the lower part 72 of the valve box, a plate valve element 8 (to be described later) is fixed by means such as bolt tightening so as to maintain a slidable space.

The plate valve body 8 is made of a rectangular plate, and is allowed to move forward and backward (left and right directions in FIG. 2) by sliding in close contact between the upper part 11 and the lower part T2 of the valve box by means of a driving means 8a.

The valve body 8 is provided with a valve hole 81 that coincides with the valve hole outlet holes 7a and 7b so that the valve is opened in its most advanced position (rightward movement in FIG. 2).

In order to seal the gap between the valve box 7 and the plate valve body 8, a tenth
A ring 11 and a twentieth ring 12 can be provided.

That is, the 101st ring 11 is provided below the valve box upper part 71, concentrically with the inlet hole 7a, and at a position where the valve plate body 8 comes into sliding contact, and the 20th ring 12 is located outside the 101st ring and is spaced apart from the inlet hole 7a. They are located outside the valve hole 81 even when the valve is fully closed, and are provided on the lower side of the upper part of the valve box and on the upper side of the lower part of the valve box so as to sandwich the plate valve body 8 from above and below.

A valve fully closed sensing switch 13 and a valve fully open sensing switch 14 are arranged side by side at the upper left end of the valve box 1 via a mounting plate.

On the other hand, at the end of the plate valve body 8, both the switches 13 and 14
A plate cam 15 is disposed at a position opposite to and in contact with the sensing lever.

The water supply and drainage pipe 10 has one end communicated with the internal water supply and drainage port 6b, and the other end is branched into an external water supply port 10a and an external discharge port 10b, each of which is provided with a switching valve (not shown). .

Incidentally, reference numeral 16 in FIG. 3 is a gasket for bringing the rice washing chamber 1 and the water supply/drainage connection part 6 into close contact.

Next, the operating state will be explained.

When the valve mechanism 70 is in the closed state, the rice A settles and accumulates in the reduced-diameter lower part of the rice washing chamber 1, but when the washing water valve 4 is opened, water is ejected from the injection pipe 3a and flows along the arrow B. Reversing member 5
The object is struck by the object, and further falls in the direction of arrow C.

The above steps are repeated to wash the rice. Water contaminated by rice washing overflows from the upper drainage port 1b, and floating matter is discharged at the same time.

However, a large amount of sewage remains in the rice washing room 1.

Therefore, the pulp of the external drain port 10b of the water supply and drainage pipe 10 is opened to drain all the waste water.

In this case, sugar is also discharged, so the cooked rice is less likely to spoil.

When all the waste water has been drained, the drain port 10b is closed, and the external water supply port 10a is opened to supply clean water and drain the water again.This water supply and water supply are repeated several times to perform a rinsing action.

Thereafter, an appropriate amount of water corresponding to the amount of rice is injected into the rice washing chamber 1 from the external water supply port 10a.

Then, the valve at the water supply and drainage port is closed, the plate valve body 8 is moved by the drive means 8a to open it, and washed rice mixed with rice water or mixed rice is fed into the pot B via the supply pipe 9.

At this point, the rice being washed contains moisture and expands, and is pushed from above the plate valve body 8 to the lower part of the rice washing chamber 1 and becomes clogged, creating a crosslinked state.

Therefore, when water is supplied from the water supply and drainage pipe 10, the rice in a cross-linked state is pushed up to the lower part of the rice washing chamber by the water supplied from below the rice washing chamber 1, and the rice on the lever plate valve body 8 is also lifted up by this. leading to.

In this way, the mixing of rice and water is promoted and the rice is rapidly cleaned.

If the water supply and drainage pipe 10 is opened in a tangential direction to the outer circumferential surface of the rice washing through hole 6a, an upward vortex will be generated during water supply, which will help purify the water.

Since the valve box 7 and the plate valve body 8 are sealed with an O-ring made of two layers (eleventh and second), no water leaks from this part.

As described above, this invention places the rice washing room and rice cooker above and below,
The two are connected by a water supply and drainage connection, a washed rice input gate valve mechanism, and a washed rice supply pipe that hangs vertically. An annular internal water supply/drainage port connected to a water supply/drainage pipe is bored around the periphery, partitioned by a filter that prevents rice from being discharged, and the rice is supplied and drained after washing through the filter.

Therefore, the rice that has swollen with moisture and is in a cross-linked state near the bottom of the rice washing chamber is pushed up, and the rice and water are mixed very smoothly, resulting in a great effect on water purification.

In addition, since wastewater mixed with dirt and bran is discharged from the same annular intake and drain port, all the wastewater in the rice washing chamber is discharged.

Therefore, rice cooked with rice washed in this way is less likely to rot and has no unpleasant odor.

Moreover, since both water absorption and drainage are performed in one port, the dirt and bran that get stuck in the filter during drainage can be removed.
When water is absorbed, it is separated from the filter by a so-called backwash floating action, and the filter holes are constantly washed by water absorption.

In addition, the entire system is compact, does not require a large installation area, saves resources, and can be provided at low cost.
