Description

  The present invention relates to a device for cleaning fine powders and the like adhering to the surface of cereal grains represented by so-called rice-cutting. It relates to the improvement of the grain scouring machine that realizes shortening and reduction of burden.

  Washing of grains such as washed rice is very painful by people, such as those who suffer from scratching or wiping in their hands, or those who are injured, etc. Especially in winter, it is a painful work because the hands are cold and cold.

For this reason, many manual-type rice washers have been invented so that rice washing can be performed more easily than before. Specifically, these inventions roughly include a container body for containing rice, and a rotation within the container body. (See, for example, Patent Documents 1, 2, and 3).
However, in many of these, the stirrer is rotatably supported, and most of them have only a simple stirring action of rice, and the pressure of the stirrer against the rice cannot be changed. It is difficult to say that the rice washing operation can be performed more efficiently, although the pain of exposing the hands to the rice can be removed. In addition, rice can be rotated in the same orbit by the stirring body, and there has been no grain scourer that is circulated over the entire bottom of the container body.

  The present invention has been made from such a background, and it is possible to change the pressure with which the stirring body is pressed against grains such as rice to be cleaned, and the grains to be cleaned are the container body. It is intended to realize a grain washer that is circulated throughout the bottom.

That is, the grain scourer according to claim 1 comprises a bottomed cylindrical container body having an open top surface, and a stirring body for stirring the grains placed in the container body together with water, In the equipment for cleaning grains,
The container main body has a substantially cylindrical peripheral wall and a bottom part connected to the substantially cylindrical peripheral wall, and the peripheral wall and the bottom part have a shape that smoothly curves by curving the peripheral edge of the bottom part, while the stirrer is not connected to the container main body. The stirrer is combined in a fixed state , and the stirrer is composed of a plurality of wire rod-shaped members and a circular support rod connecting the wire rod-shaped members at the upper portion, and is configured as a bowl-shaped rod as a whole. Is arranged substantially vertically from the peripheral wall of the container body with a gap between them, and is further rounded in accordance with the shape of the container body at a portion near the bottom periphery, and further rises from here to the center. is formed so as to concentrate in the center, thereby, the center of the bottom surface of the agitation body, der those comprising as a feature in that in a state floating from the concave to the container body bottom upward as viewed from below .

  In addition to the above requirements, the grain washing machine according to claim 2 has a mesh having a size that opens a drain outlet and prevents the grain from flowing out at a predetermined height of the peripheral wall of the container body. It is characterized by the stretched net.

  Furthermore, in addition to the said requirements, the said grain masher of Claim 3 is characterized by the said grain being rice.

The grain polisher of the present invention has the following effects by the means described above.
That is, according to the grain washing machine according to claim 1, the stirring action part in the stirring body uses a plurality of wire rod-like members, and the bowl shape is close to the inner shape of the bowl shape of the container body. It is formed in a shape, and the bottom center of this stirring body is recessed upward as seen from below, so put the grains together with water into the container body, and rotate and stop the stirring body When the stirring body rotates, the vortex flow caused by the stirring causes the grains to move toward the peripheral wall of the container body and be polished, and when stopped, the spiral water flow disappears, and the bowl-shaped inner surface shape of the container body and the bottom surface of the stirring body Immediate return to the center of the container body from the central recess. There is no bias in the grains to be polished by the circulation movement between the peripheral wall and the center of such grains, and the polishing is performed uniformly, and the completion of the polishing in a short time is achieved.
In addition, since the stirring body is not supported by a rotating shaft or the like, the pressing force on the rice can be adjusted freely, and the stirring portion is formed using a number of wire rod members and has elasticity. Therefore, it matches the shape of the container body more and has a high cleaning power. Such an effect is very advantageous because the present invention is intended not only for rice but also for multiple types of foods. In addition, since it has a simple structure, failure is unlikely to occur and manufacturing costs can be kept relatively low.

  According to the grain washer according to claim 2, a mesh body having a mesh size that opens the drainage port and prevents the grain from flowing out at a predetermined height of the peripheral wall of the container body. Because it is installed, the grains are washed and polished while pouring water, and the dirty polishing water is drained from the drain outlet as needed. Moreover, when draining all dirty washing water, if it drains from this drain outlet, the grains inside will not flow out.

  Further, according to the grain washing machine according to claim 3, when the grain is rice, the rice cake attached to the rice can be quickly and cleanly removed, so that the hands are not tired and the tap water is saved. It also becomes. Moreover, since it is not necessary to put a hand on water, there is also an effect of preventing and suppressing redheads and frostiness. In ordinary households, rice is washed almost once to several times every day, so the merit of using a grain scourer becomes extremely large when added over the long term.

  The best mode of the grain washing machine of the present invention is specifically described in the following examples.

The present invention will be described below based on the illustrated embodiments. What is indicated by the symbol A in the figure is a grain washing machine according to the present invention, a container body 1 having an open upper surface, and a stirring body 2 for stirring grains placed in the container body 1 together with water W. And comprising.
In the present embodiment, an example of washing white rice will be described as an example, but the grains to which the grain washing machine A of the present invention can be applied include, in addition to white rice, brown rice, soybeans, potatoes and Various things such as buckwheat berries can be applied.
Hereinafter, each member will be described in detail.

The container body 1 will be described. The container main body 1 is a container that receives grains and stirs the grains together with the water W by the stirring body 2 and cleans them.
The container body 1 has a bottomed cylindrical shape. As an example, a plurality of drainage ports 11 are opened from about a half of the peripheral wall 10 to a half circumferential surface at an upper height position. A mesh body 12 having a size to prevent the outflow of the like is stretched. Further, a handle 13 for supporting the container body 1 at the time of polishing is provided on the outer surface of the upper part of the peripheral wall 10. The handle 13 is formed in a bowl shape and can be used as a hook for hanging when not in use. On the other hand, the bottom part 14 in the container main body 1 is formed in a bowl shape having a rounded bottom periphery. Incidentally, if the drainage port 11 has sufficient strength depending on the material of the container body 1 or the like, a plurality of drainage ports 11 are not provided, but a single drainage port having a large area where three drainage ports 11 are connected. It is also preferable from the viewpoint of production.

  The stirring body 2 will be described. The stirrer 2 is installed at a stirring action portion 20 formed by a plurality of wire rod-like members 21, an annular support frame 22 that fixes and supports the wire rod-like members 21 at the upper portion, and the center of the support frame 22. A horizontal reinforcing rod 23 and a vertical reinforcing rod 24 connecting the center of the horizontal reinforcing rod 23 and the center of the bottom of the agitating portion 20. Further, on one end side of the horizontal reinforcing rod 23, a handle arm 25 is raised upward, and a handle 26 for rotating the agitator 2 is rotatably provided to the handle arm 25. ing. Incidentally, the stirring by the stirrer 2 is performed by holding the handle 26 or by rotating the horizontal reinforcing rod 23. If anything, the rotating by holding the horizontal reinforcing rod 23 is more effective for the rice R. Easy to fine-tune the pressing force. Therefore, it is preferable that the handle arm 25 is configured to be easily detachable from the horizontal reinforcing rod 23 by using a thumbscrew or the like, assuming that the handle 26 is not used.

The stirring action part 20 as a whole is formed in a bowl shape along the bowl-shaped inner surface shape of the container body 1, and as a feature of the present invention, the center of the bottom surface is recessed about 1 cm as an example upward. It has the depressed part 20a. The concave portion 20a is for urging the rice R to return to the central direction toward the peripheral wall 10 of the container body 1 during stirring. However, if the concave portion 20a is large, the returning action is large, and the stirring force and washing force are increased. On the contrary, when the recessed portion 20a is small, the returning action is weak and the stirring force and the cleaning power are strong.
Further, the stirring action part 20 is formed so that the diameter is slightly smaller than the diameter of the container main body 1, and the peripheral side part of the stirring action part 20 is brought close to the peripheral wall 10 of the container main body 1 with a small gap interval g. The diameter of the stirring action part 20 is about 2 cm smaller than the diameter of the container body 1.

  In consideration of strength and hygiene, the material of the container body 1 and the stirring body 2 is preferably made of stainless steel for many parts. For example, a synthetic resin is used for the container body 1 or the wire of the stirring body 2 is used. The rod-shaped member 21 may be implemented using a wire made of various materials, for example, a general ordinary wire obtained by applying zinc plating to iron instead of a stainless steel wire.

An example of the grain scourer A of the present invention has the above-described specific form, and this operation mode will be described below.
First, as shown in FIGS. 4A, 4 </ b> B, and 4 </ b> C, rice R is put into the container main body 1, water W is added, and the stirring body 2 is inserted into the container main body 1 and placed. In addition, the order which puts the stirring body 2, the rice R, and the water W in the container main body 1 can be performed in an appropriate order according to a user's preference. And after the preparation of the rice washing is completed as mentioned above, the stirring body 2 is stirred and the rice washing is performed.

  Specifically, the stirring mode is such that the container body 1 is supported by holding the handle 13 with one hand and the center of the horizontal reinforcing rod 23 or the handle 26 is held by the other hand with the hand as an example. Wash rice by rotating 2 forward and backward half turn. Since the stirring body 2 is not supported by the rotating shaft or the like, the pressing force on the rice R can be adjusted freely, and the stirring body 2 is elastic because of the wire rod-like member 21. The cleaning power is high as long as it conforms to the shape of the container body 1 and does not break or crush the rice R. In addition, at the time of washing the rice, water W such as tap water may be always poured into the container body 1 to wash the rice, or the water W may be poured at an appropriate interval. Moreover, it is preferable not only to rotate the stirring body 2, but also to perform an operation of pressing the rice R by moving it up and down appropriately. The rice R is rubbed between the wire rod-like member 21 and the container body 1 and stirred, so that the wrinkles attached to the surface of the rice R are removed.

  The movement of the rice R during stirring will be described in more detail. As shown in FIGS. 4 (d), 5 (a), and 5 (b), the center of the bottom of the container body 1 is centered when the stirring body 2 is being stirred. The rice R, which is swirled and stirred, approaches the peripheral wall 10 of the container body 1. Then, when stirring is stopped for several seconds, the vortex disappears and the rice R returns to the center as shown in FIGS. 4 (e), 6 (a) and 6 (b). At this time, the bottom 14 of the container body 1 is formed in a bowl shape and is inclined toward the center of the bottom, and the bottom center of the stirrer 2 is recessed upward. The return to the center of the main body 1 is fast. By the way, emphasizing the return of the rice R to the center of the container body 1 and increasing the degree of the depression excessively reduces the area of the bottom surface in contact with the rice R, which is not preferable because the polishing force and the stirring force are extremely attenuated. . When the stirring is resumed, the rice R is again stirred toward the peripheral wall 10 of the container body 1 by the vortex. The rice R is directly agitated at a large number of locations by a plurality of wire rod-shaped members 21 and the rice R is actively circulated between the peripheral wall 10 and the center side of the container body 1 by the recessed portion 20a of the agitator 2. As a result, the efficiency of washing rice is significantly higher than when stirring by hand.

  Further, at the time of cleaning, excess water W is drained from the drain port 11. And since the net body 12 is stretched in the drain outlet 11, the rice R does not flow out with the water W. In addition, the water W (togi soup) that has become cloudy is thrown away by tilting the container body 1 from the drain outlet 11 as shown in FIG. At this time, the rice R does not flow out from the drain port 11, which is economical. In addition, after use, the container main body 1 can be suitably hung at a place with a bowl-shaped handle 13 and dried.

  When the tomato soup becomes transparent and the washing is finished, as shown in FIG. 4 (g), the container body 1 is tilted with the one not provided with the drain port 11 as a lower part, and the rice R inside is cooked together with the water W for cooking rice. Move to.

  When potatoes are cleaned, a relatively small potato is placed on the stirrer 2 after the stirrer 2 is inserted and placed in the container body 1 and stirred together with the water W. In this way, when the grain washing machine A of the present invention is used for potato polishing, the potato is peeled.

It is a perspective view which shows a grain scourer of the present invention partially broken. It is a longitudinal side view same as the above. It is a perspective view same as the above. It is explanatory drawing which shows the whole action | operation aspect in the grain washer. It is a vertical side view and a transverse plan view showing an operation mode at the time of stirring in a grain scourer.
