Description

  The present invention relates to an improvement of a rice mill, and more particularly, to an improvement of an upper lid (or a rice receiving container) installed at a brown rice input opening of the rice mill.

Patent Documents 1 and 2 describe a rice milling machine in which a hopper is installed in the upper part of the casing, an opening for feeding brown rice into the hopper is formed on the upper surface of the casing, and the introduced brown rice is polished and discharged downward. ing.
The rice milling machine described in Patent Document 1 is a so-called one-time rice milling machine, and the brown rice that has entered the milling section from the hopper is fed forward by a rotating feed roll, and the milling roll and the removal casing of the milling section are fed forward. It moves toward the discharge port at the tip while receiving friction between them, and in the process, it is refined to become polished rice, overflows from the discharge port against the pressure of the resistance lid, falls and falls into the lower rice receiving container. On the other hand, the separated soot is pulled out from the hole of the removal casing and falls and enters the lower soot receiving container.

  Further, the rice milling machine described in Patent Document 2 is a so-called circulation type rice milling machine, and the brown rice that has entered the milling section from the hopper is fed forward by a rotating rice milling roll, and friction is generated between the rice milling roll and the demolding casing. Passing through and returning to the hopper again, this cycle is repeated and gradually refined and becomes milled rice. When the milling is finished and the shutter installed in the circulation passage is opened, the milled rice enters the lower rice receiving container. On the other hand, the separated soot comes out of the hole of the demolding casing, and in this example, enters the lower soot receiving container via the cyclone device.

JP 2000-237611 A (FIG. 3) JP 2003-311165 A

In a conventional rice mill, a rice receiving container and a rice bran receiving container, and in some cases, a brown rice supply container (measuring container) are provided as a set as an accessory for each application. Naturally, the cost of each part is incurred, raising the cost of the entire rice mill.
The present invention has been made in view of the current situation of such a rice milling machine, and aims to reduce the cost of parts and reduce the cost of the rice milling machine.

  The present invention is a rice milling machine in which a hopper is installed in the upper part of the casing, an opening for introducing brown rice into the hopper is formed on the upper surface of the casing, and the opened brown rice is polished and discharged downward. The top lid installed in the plant is also used as a rice receiving container, reducing the number of accessory parts and reducing costs. More specifically, the structure of the upper lid is constituted by a ceiling wall that fits in the opening and a cylindrical wall formed thereunder, and when this is inverted, the rice receiving container having the ceiling wall as the bottom wall It was made to become. Also, a handle is formed on each of the outside of the cylindrical wall and the ceiling wall so that the handle can be held both when the upper lid is used for the original use (upper lid) and when it is used upside down as a rice receiving container. I made it.

It is preferable that the upper lid is formed by integrally molding plastic for at least the ceiling wall and the cylindrical wall (more preferably, the entire body including the handle is integrally molded). It is desirable that a flange portion protruding outward from the cylindrical wall is formed on all or part of the periphery of the cylindrical wall. When the ceiling wall of the upper lid has a flange portion, a step portion is formed at the inner edge of the opening, and when the upper lid is installed in the opening, the flange portion is locked to the step portion. It is desirable.
Further, when the upper lid is installed in the opening, the lower end of the cylindrical wall may be locked in the hopper. In this case, the stepped portion for locking the flange portion is not necessary.

  The upper lid can also be used as a brown rice supply container. In this case, if the volume of the container (the volume inside the cylindrical wall) is determined to be a predetermined value, for example, 3 or so, it becomes a substitute for a measuring instrument, or if a measuring mark is attached to the cylindrical wall, an appropriate amount We can weigh brown rice and are more convenient. By using the upper lid also as a brown rice supply container, the number of parts can be further reduced and the cost of the rice milling machine can be reduced.

Since the upper cover of the rice mill according to the present invention also serves as a rice receiving container and also serves as a brown rice supply container if necessary, the number of parts can be reduced and the cost of the rice mill can be reduced.
The upper lid does not need to be put on the opening during milled rice, and is always removed (that is, unnecessary) when brown rice is fed to the hopper, so it is used as a rice receiving container during milled rice and when brown rice is fed. There is no problem in serving as a brown rice supply container.
When the upper lid, rice receiving container and brown rice supply container are all prepared as before, for example, the upper lid and brown rice supply container which are unnecessary during milling are unnecessary and the rice receiving container and brown rice supply container which are unnecessary during storage (when not in use) However, the same parts were scattered unconsciously and sometimes dissipated, but in the present invention, as the upper lid during storage, as a rice receiving container during milled rice, and as a brown rice supply container during brown rice supply By continuing to use, it is possible to prevent the parts from being lost or lost.

It is sectional drawing of the rice milling machine which concerns on this invention. It is a top view of FIG. It is a top view of the upper lid concerning the present invention. FIG. 4 is a front view of FIG. 3. FIG. 4 is a left side view of FIG. 3.

Hereinafter, a rice mill and an upper lid according to the present invention will be described with reference to FIGS.
The rice mill shown in FIGS. 1 and 2 is a one-time rice milling machine of the same type as that of Patent Document 1, and a hopper 2, a rice milling device 3, a motor 4, and the like are arranged in a plastic casing 1.
The hopper 2 is made of plastic, is arranged at the upper part in the casing 1, and continues to an opening 5 formed on the upper surface of the casing 1. The upper half portion of the hopper 2 is an upper lid accommodating portion 2a, and is formed to have approximately the same size as the opening 5 (however, it becomes narrower as it goes downward due to a draft angle during molding). The lower half of the hopper 2 is narrowed and communicates with the inside of the rice milling apparatus 3 at the narrowed portion 2b at the lower end.

The structure of the rice milling device 3 is essentially the same as that described in Patent Document 1 or Japanese Patent Application Laid-Open No. 7-1000039, and a feed roll unit 7a in which screws opposite to each other are formed inside the milling unit 6. And a roll 7 having a fine roll part 7b is rotatably arranged. The periphery of the handling roll portion 7a and the finening roll portion 7b is surrounded by a cylindrical handling casing 6a and a finening casing 6b, and both casings 6a and 6b constitute the outer shape of the finening portion 6. A hole (passage) communicating with the narrowed portion 2b is formed in the upper portion of the operation casing 6a, and a number of holes (slits) are formed around the fine casing 6b (not shown). The precision unit 6 is supported at a predetermined position by a bracket 9 or the like which will be described later.
A resistance lid 8 is installed at the discharge outlet at the tip of the polishing casing 6b and is pressed against the tip of the polishing casing 6b with a predetermined adjustable pressure.

The motor 4 is installed on a bracket 9 fixed to the bottom of the casing 1, and its power rotates the roll 7 via the pulley 11, the belt 12 and the pulley 13.
In addition, a mill guide member 14 is disposed from the periphery of the milling casing 6b to the lower side, and a rice mill guide member 15 is disposed below the discharge port at the tip of the milling casing 6b. At the time of rice milling, a rice bran receiving container 16 is installed at a position below the rice bran guide member 14, and a rice receiving container (partially shown by a one-dot chain line in FIG. 1) is arranged below the rice milling guide member 15. .

The function of the rice milling device 3 is essentially the same as that described in Patent Document 1 or Japanese Patent Application Laid-Open No. 7-1000039, and the brown rice put into the hopper 2 is fed out from the narrowed portion 2b to the milling portion 6 6a enters and rotates forward by a rotating roll 7a, and then proceeds toward the discharge outlet at the tip while receiving friction between the finer roll 7b and the demolding casing 6b. Then, the rice becomes milled, overflows from the discharge port at the tip against the pressure of the resistance lid 8, falls by being guided by the milled rice guide member 15, and enters a rice receiving container described later.
On the other hand, the rice cake is separated from the brown rice between the milling roll portion 7b and the rice removal casing 6b, and the rice cake comes out of the hole around the rice removal casing 6b, falls while being guided by the rice cake guide member 14, and dropped into the rice cake receiving container 16 to go into.

1 and 2 show a state in which the upper lid 17 is installed in the opening 5.
The upper lid 17 is an integrally molded body of plastic, and as shown in FIGS. 3 to 5, from a ceiling wall 18, a cylindrical wall 19 formed thereunder, and a handle 21 formed outside the cylindrical wall 19. Become.
The cylindrical wall 19 has substantially the same height (depth) on the entire periphery, is given a draft on the entire periphery for convenience of molding, and is slightly inclined in a direction of spreading downward from the ceiling wall 18. Although it has a substantially rectangular tube shape in a plan view, a spout 22 is formed on the opposite side of the handle 21 so as to project on a substantially arc.
The ceiling wall 18 has a flange portion 23 that protrudes to the outer peripheral side from the cylindrical wall 19 around the entire circumference of the cylindrical wall 19, and the flange portion 23 protrudes largely in the vicinity of the handle 21 (flange portion 23 a). The handle 21 has an upper end coupled to the flange portion 23a from below, and a lower end extending to and connected to the side surface of the cylindrical wall 19. The ceiling wall is formed in a substantially flat plate shape as a whole, there is no portion projecting upward, and a handle 24 comprising a pair of depressions (portions projecting downward) is formed in a substantially central portion.

In this rice milling machine, the upper lid 17 functions as an upper lid when the ceiling wall 18 is turned up, and functions as a container when it is turned upside down (the ceiling wall 18 is lowered). When the upper lid 17 is used as an upper lid, the handle 24 may be picked from the outside, and when used as a container, the handle 21 may be picked.
An upper lid 17 indicated by a solid line in FIGS. 1 and 2 is used as an upper lid and is installed in the opening 5. A step portion 25 is formed on the entire inner edge of the opening 5, and the flange portion 23 of the ceiling wall 18 of the upper lid 17 is locked to the step portion 25, and the upper surface of the ceiling wall 18 is substantially flush with the upper surface of the casing 1. Located at the height of The cylindrical wall 19 and the handle 21 of the upper lid 17 pass through the inside of the step portion 25 and are arranged in the upper lid accommodating portion 2a of the hopper 2.

As shown in FIG. 1, the upper lid accommodating portion 2a of the hopper 2 is provided with a draft angle on the entire circumference for the sake of molding, and this draft angle is opposite to the cylindrical wall 19 of the upper lid 17 (upwardly). In the direction of spreading). Therefore, if the ceiling wall 18 of the upper lid 17 does not have the flange portion 23, a large gap is formed between the inner peripheral edge of the opening 5 and the outer peripheral edge of the ceiling wall 18, but the ceiling wall 18 has the flange portion 23. This gap S (see FIG. 2) can be set to a minimum.
In the above example, the step portion 25 is formed on the entire inner edge of the opening 5, and the flange portion 23 of the ceiling plate 18 of the upper lid 17 is locked to the step portion 25. The upper lid 17 can also be installed in the opening 5 by forming a locking portion for locking the lower end of the cylindrical wall 19 of the upper lid 17 and locking the cylindrical portion 19 to the locking portion.

An upper lid 17 indicated by a two-dot chain line (virtual line) in FIG. 1 is in a state when used as a rice receiving container. The upper lid 17 is upside down, and the ceiling wall 18 is placed on the floor.
Further, the upper lid 17 can also be used as a brown rice supply container (measuring instrument). In this case, it is desirable that a measuring mark (for example, a measuring line such as 2 or 3 go) is attached to the cylindrical wall 19.
If the volume of the brown rice supply container (upper lid 17) is smaller than the volume of the hopper 2, the brown rice overflows from the hopper 2 even if the brown rice supply container (upper lid 17) is filled with the full amount of brown rice. There is no. Moreover, since the volume of the polished rice is smaller than the volume of the brown rice, the finished polished rice does not overflow from the rice receiving container (upper lid 17).

Next, an example of usage of the upper lid 17 of the rice mill will be described.
(1) The handle 24 is picked and the upper lid 17 is removed, the upper lid 17 is turned upside down, the brown rice is weighed, the handle 21 is picked and put into the hopper 2 from the spout 22 through the opening 5. At this time, the upper lid 17 is used as a brown rice supply container.
(2) As shown by a two-dot chain line in FIG. 1, the top lid 17 is placed under the rice milling guide member 15 with the top and bottom inverted. At this time, the upper lid 17 is used as a rice receiving container.
(3) Turn on the motor 4 and start the rice milling. The milled rice falls through the milled rice guide member 15 into the upper lid 17 (rice receiving container), and the rice bran enters the basket receiving container 16 through the rice bran guide member 14.
(4) When the milling is finished, the milled rice in the upper lid 17 (rice receiving container) is transferred to the pot of the rice cooker, returned to the original position (with the ceiling wall 19 up), and the handle 24 is picked and fitted into the opening 5 Put in. From this time, the upper lid 17 is used again as the upper lid of the opening 5.

  Although the above description has been described by exemplifying a rice milling machine once, the upper lid according to the present invention can also be applied as an upper lid of a circulation type rice milling machine.
