Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a rice washing apparatus, particularly in a kitchen of a rice supplier such as a restaurant or sushi restaurant, which is arranged in a limited space and suitable for providing rice by cooking a relatively small amount of rice at short intervals. This relates to a rice washing apparatus.
[0002]
[Prior art]
Conventionally, in commercial kitchens such as general hotels, restaurants, sushi restaurants, etc., in order to wash a large amount of rice efficiently and with stable quality without manual labor, Automatic rice preparation equipment, automatic rice cooking equipment, etc. are used. As an example of such an apparatus, for example, as disclosed in Japanese Patent Application Laid-Open No. 53-115866, storage of milled rice, weighing and sorting, feeding into the rice washing section, water supply, washing, sharpening, An automatic rice washing device that automatically executes various processes such as wastewater separation drainage, metered water supply for rice cooking water, and discharge and input of rice washing and rice cooking water into a rice cooking container is known and put into practical use.
[0003]
The automatic rice washing apparatus described in the above publication has a structure in which a rice storage is provided at the lower part, a rice washing part is provided at the upper part, and a placing table for placing a rice cooking container or a rice cooker is disposed between them. At the bottom of the rice storage is a rice weighing and sorting means consisting of a rotating cylinder and a small hopper. Rice from this small hopper is introduced into a depressurized rice washing container through a feeding pipe, and the rice washing container The rice is washed inside, and water for cooking rice is metered and discharged into a rice cooking container or rice cooker.
[0004]
Moreover, in the apparatus disclosed by Unexamined-Japanese-Patent No. 47-22271, it is the structure which arrange | positioned the rice storage in the upper part, arrange | positioned the rice cooking container or the rice cooker in the lower part, and provided the rice-washing part among them. .
However, in the case where the rice storage is provided in the apparatus as described above, the structure is usually complicated and the cost is increased.
[0005]
On the other hand, in the type having a rice cooker in the apparatus, gas piping or electric wiring is necessary to supply heat for rice cooking, and its movement is not easy due to its large weight, and therefore It is usually a rice cooker stationary type.
However, while the time required for washing the rice is about 5 minutes, for example, the total time required for the rice cooking process in a series of steps such as soaking, rice cooking, and steaming is very long. The efficiency is low and the rice cooking process cannot be performed frequently at short intervals.
[0006]
Moreover, in a large-sized automatic rice cooking apparatus, there is a case where a small amount of rice cannot be cooked, and the minimum amount of rice cooking cannot be made sufficiently small.
[0007]
On the other hand, recently, due to intensifying competition in the restaurant industry, demand for not only cost but also flavor quality of cooked rice has increased, and the time from cooking to provision as a product has been shortened. In order to prevent the deterioration and stabilize the quality of cooked rice, the tendency to reduce the amount of cooked rice in each cooked rice by shortening the time interval of cooked rice is large. For example, about 1 kg of packed rice (packaging) in one cooked rice There is also an example where rice is packed or sealed in a bag and then cooked at 10-minute intervals.
In particular, in the final rice cooking process, in order to reduce the remaining amount of cooked rice, there is a case where one packed rice should be further divided and processed. It is necessary to provide a large number of small rice cookers.
[0008]
In kitchens where small rice washing devices such as those mentioned above are used, for example, in the case of the large-scale restaurant industry that has a large number of chain stores, there is a rice storage warehouse because its own small packed rice is used. It is often not provided, and in this case, it is necessary to perform a considerably heavy work to open the packed rice every time the rice is washed and to introduce the rice into the inlet of the rice washing container. There are also advantages.
[0009]
In other words, since no rice storage, rice metering device, rice feeding device, etc. are required, the rice washing device can be made small and light, and the packed rice is small so that it can be stored temporarily. Space can be used, and the rice is sealed in a packaging bag so that it is not easily altered and hygienic. Furthermore, the number of rice cooking processes and the total amount of processing can be easily managed. This is a great advantage in business management.
[0010]
In addition, packed rice generally has high weighing accuracy, and if necessary, it is possible to check the quantity before processing, and the inventory quantity can be easily checked visually, so it is easy to manage on-site, and if necessary, It is easy to change the type, and further, since the weighing process and the rice feeding process are unnecessary, the generated noise is extremely low and the contamination in the apparatus is also small.
[0011]
As a commercial rice washing apparatus that utilizes the advantages of such packed rice, one having the configuration shown in FIG. 15 has been conventionally used.
The rice washing preparation device 80 includes a gantry 81 supported on the floor surface FL, and the gantry 81 has a placing portion 83 for placing a rice washing receiving container or a rice cooker. A rice washing container 90 is provided at an upper portion of the column 82 rising from the rear portion of the gantry 81 so as to be positioned above the placement unit 83. The entire rice washing container 90 has a substantially cylindrical shape, and a drive mechanism housing portion 91 is provided at an upper portion thereof so as to be slightly displaced in the rear direction (rightward in the drawing). A rice hopper 93 that expands upward while being connected to the opening formed at the top is provided, and a rice inlet 94 is formed by the upper end opening of the rice hopper 93. 94A is a cover plate of the rice inlet 94.
[0012]
In the drive mechanism accommodating part 91, a part of drive means for a water supply means and a stirring means is arrange | positioned, for example.
The rice washing container 90 is provided with rice discharging means 96 through a truncated cone-shaped portion 95 at the lower part, and the rice washing receiving container 100 is placed on the mounting portion 83 of the gantry 81 so as to be located immediately below the rice discharging port facing downward. Placed in.
85 is a water distribution pipe extending in the horizontal direction from the lower end of the rice washing container 90, and 86 is a drainage box having a drain valve connected to the water distribution pipe 85 and supported by a support 82.
[0013]
FIG. 16 shows a conventional rice washing device of a desktop type compatible with packed rice. In this example, the gantry is configured in a mere flat plate shape, and is different from the above in that it is a placing portion 83. 15 is the same as the apparatus shown in FIG. 15, and the rice inlet 94 is constituted by a rice hopper 93. Reference numeral 98 denotes an operation panel.
[0014]
In the conventional rice washing apparatus as described above, it is important to hold the rice washing container or rice cooker that receives the washed rice and rice cooking water at a height position where good workability is obtained. The height position of the rice input port 94 becomes a considerable height from the floor surface FL, so that it is not always easy to reliably input the rice from the packaging bag into the rice input hopper 93. is there.
[0015]
In addition, since the rice throwing hopper 93 is disposed at the front position of the drive mechanism accommodating portion 91, the position of the operation panel 98 provided on the front surface of the drive mechanism accommodating portion 91 is usually higher than the rice throwing hopper 93. Therefore, operation of the operation panel 98 becomes difficult. Further, since the rice inlet 94 is narrow, it is almost impossible to check the state of the rice washing container 90 or clean the inside of the rice washing container 90 through the rice inlet 94. It is necessary to form a confirmation window and an openable / closable cleaning opening on the wall of the rice washing container 90. Reference numeral 97 denotes a transparent front cover that closes such a window or opening.
[0016]

Embodiments of the present invention will be described below with reference to the drawings based on specific examples.
[0028]
【Example】
<Example 1>
FIG. 1 is a side view for explaining the rice washing apparatus according to the first embodiment of the present invention. In the rice washing apparatus 10 of this example, a pair of support legs 11 extending in the horizontal direction for supporting the entire apparatus on the horizontal floor surface FL are arranged in the left and right lateral directions (in FIG. In a direction perpendicular to the direction). A support substrate 13 extending forward in the horizontal direction is supported on the upper end of the support column 12 rising upward from the rear portion of the support leg 11, and the rice washing container 14 is suspended on the support substrate 13 so as to hang downward. A drive mechanism housing portion 15 is provided so as to be supported and to protrude above the support substrate 13. In addition, a rice wash receiving container placing plate 18 for supporting the rice wash receiving container 100 is fixed to the column 12 so as to be positioned below the rice wash container 14.
[0029]
2 is a plan view for explaining the apparatus of FIG. 1, FIG. 3 is a sectional view for explaining the apparatus of FIG. 1, and FIG. 4 is an enlarged view of a rice washing container portion of the apparatus of FIG.
As shown in FIG. 3, the rice washing container 14 has a conical cylinder shape which will be described later in detail, and a rice discharging means 20 is provided at the lower end portion thereof. This rice discharging means 20 has an on-off valve 21 that moves up and down to open and close the lower end opening of the rice washing container 14, and the upper end of the drive rod 22 that extends in the rice washing container 14 above the on-off valve 21 is the drive mechanism housing portion 15. It is provided in a state extending inward.
[0030]
In addition, rod-shaped stirring means 25 having a rod-shaped portion extending along the inclined inner peripheral surface of the rice-washing container 14 is provided around the axis extending in the vertical direction of the rice-washing container 14. It is arranged to rotate. Specifically, the agitation means 25 is fixed to a drive sleeve 26 that is rotatably provided around the drive rod 22, and the drive sleeve 26 is provided so as to extend into the drive mechanism housing portion 15. ing.
Furthermore, water supply means (not shown) for supplying cleaning water and rice cooking water is provided in the rice cleaning container 14.
[0031]
Further, at the lower end portion of the rice washing container 14, washing sewage drainage means for separating and discharging the washing sewage from the rice is provided. As shown in FIG. 4, this washing wastewater drainage means communicates with a chamber 40 in which the on-off valve 21 moves up and down, and has a water distribution pipe 41 projecting outward in the horizontal direction therefrom, and a drain connected to the water distribution pipe 41. It is composed of a box 42. A drainage channel extending from an overflow water discharge unit, which will be described later, extends to the drainage box 42 and is connected to the drainage pipe 41, and a switching valve (not shown) is interposed. Reference numeral 43 denotes a front door of the drainage box 42.
[0032]
The drive mechanism housing portion 15 is provided in a region that covers a rear side portion that occupies a majority other than the front side portion of the upper end opening of the rice washing container 14. In the drive mechanism housing portion 15, a valve opening / closing motor 27 for driving the opening / closing valve 21 of the rice discharging means 20, a connecting mechanism for connecting this to the drive rod 22, and a stirring motor 28 for driving the stirring means 25. In addition, a connecting mechanism that connects the drive sleeve 26 to this, a control mechanism (not shown) for water supply means, and the like are accommodated.
[0033]
A front side portion of the upper end opening of the rice washing container 14, for example, a portion of about 1/3 of the total opening area is used as the rice inlet 30, and a lid member 31 for opening and closing the rice inlet 30 is provided at the rear end. Is hinged at the front end of the drive mechanism housing 15 so as to be pivotable up and down.
A lid member opening / closing detection means 33 is provided around the rice inlet 30. When the lid member 31 is opened, a stirring motor in the drive mechanism housing portion 15 is detected by a detection signal from the lid member opening / closing detection means 33. 28 is stopped, and the rotation of the stirring means 25 is stopped. At this time, it is preferable that the stirring motor 28 is stopped over a period of 1 to 2 seconds by being decelerated in a geometric series, thereby avoiding a trouble due to a sudden stop.
[0034]
In the apparatus of this embodiment, the rice washing container 14 has a conical cylindrical shape as a whole, and the angle (elevation angle) of the inclined inner peripheral surface with respect to the horizontal direction is, for example, 62 degrees. A range of degrees is preferred. Above this conical cylindrical portion, a cylindrical portion 35 is continuous so as to extend upward from the upper end of the sloped inner peripheral surface to reach the support substrate 13, and at the upper end of the sloped inner peripheral surface, The overflow water discharge part 36 is opened. As described above, a space is formed above the overflow water discharge portion 36 by the cylindrical portion 35, and this space is necessary as a spout space defined by the Water Supply Law.
[0035]
  Here, the diameter of the upper end opening of the rice washing container 14 is at least 300 mm or more, particularly preferably 360 mm or more.
  If a larger internal space is required, the length of the cylindrical portion 35 may be increased. However, in the present invention, the space where the washing is actually performed isConical rice washing spaceOnly.
[0036]
  As shown in FIG. 2, when the diameter a of the upper end opening of the rice washing container 14 is, for example, 360 mm, the front edge of the drive mechanism housing portion 15.soThe size of the arc-shaped rice input port 30 to be separated can have a width b of, for example, about 320 mm. Therefore, the rice input port 30 can very easily serve rice from, for example, a commercially available pack containing 1 to 5 kg. It becomes the size that can be thrown into.
[0037]
The conventional rice washing apparatus shown in FIG. 15 has a conical cylindrical portion 95 at the lower portion of the rice washing container 90, but the main body is the upper cylindrical portion, and the washing of the rice is performed inside. If the capacity of this rice washing container 90 is equivalent to, for example, the rice washing container 14 of Example 1, the diameter of the upper end opening in the rice washing container 90 is 270 mm, so that the region more than half of the upper end opening is used as the rice inlet. However, in this case, since the rice input port is narrow, the intended rice input operation is not easy as it is, and therefore the rice input hopper 93 is required.
[0038]
FIG. 5 is a comparative view for explaining the above situation. In the case of a rice washing container of the same capacity, the rice washing container 14 having a substantially conical cylindrical shape as in the first embodiment mainly has a cylindrical portion. Compared with the container 90, the height of the rice washing container itself can be significantly reduced, and the conventional rice washing container 90 is further provided with a rice hopper 93, so that the actual rice inlet level The position is very high.
Accordingly, in the conventional rice washing apparatus, not only is it difficult for a short worker to introduce rice, but it is not possible to inspect and clean the inside of the rice washing container 90 from the rice introduction port 94 of the rice introduction hopper 93. It was possible.
[0039]
However, in the rice washing container 14 of the present invention, the level position of the rice input port 30 is low and the opening area of the rice input port 30 is large, so that the rice input operation can be performed easily and reliably without using a hopper. can do. In addition, since there is no rice hopper and a wide rice inlet 30 is formed, inspection and cleaning of the inside of the rice washing container 14 can also be performed via the rice inlet 30. If the lid member 31 is opened for the introduction, the inside of the rice washing container 14 is inevitably seen from the rice introduction port 30, so that troubles such as excessive introduction of rice can be prevented.
[0040]
In the above, if the inclined inner peripheral surface of the cone-shaped rice washing container 14 has an elevation angle of, for example, 55 degrees or more, this angle is a limit for generating residual rice attached to the inner peripheral surface. Since the slope is larger than the angle (so-called angle of repose), no residual rice is produced. In the rice washing container 14 having a large elevation angle, the remaining rice is more preferable, but the height of the rice washing container 14 is increased in order to obtain a necessary internal volume. From this point of view, the elevation angle is preferably in the range of 55 to 67 degrees, particularly in the range of 60 to 65 degrees, and in particular, approximately 62 degrees is the most suitable angle, thereby increasing the diameter of the upper end opening. However, the level position of the rice inlet 30 can be set to a low position.
[0041]
For example, the diameter a of the upper end opening of the rice washing container 14 can be 360 mm, and the height d (see FIG. 1) of the rice inlet 30 from the floor surface FL can be about 1100 mm. On the other hand, in the conventional apparatus of FIG. 15 having the same capacity, the diameter of the upper end opening is 270 mm, the height c of the rice inlet 84 is about 1300 mm, and the level position of the rice inlet is as low as 200 mm. Can do.
Of course, the present invention is not limited to the above numerical values, and various modifications can be made as necessary.
[0042]
  Further, in the above-mentioned conical tube-shaped rice washing container 14,TheIn the step of stirring the rice, the rice is pressed against the inner peripheral surface of the inclined surface by the action of the centrifugal force by the stirring means 25, and then moved upward along the inner peripheral surface of the inclined surface. This behavior aids the sharpening effect as well as the stirring effect of the rice, so that the rice is sharpened and washed uniformly and with high efficiency. it can.
[0043]
Furthermore, since the rice introduced from the rice inlet 30 is immediately received by the slanted inner peripheral surface of the rice washing container 14 without sliding a large distance and slides down, the rice grains are prevented from receiving a large impact force. In addition, the generation of crushed rice can be greatly reduced, and noise is low. These effects are particularly remarkable when the rice-washing container 14 is formed of a synthetic resin material.
[0044]
In the above rice washing apparatus, an operation panel 45 is provided on the front surface of the drive mechanism housing portion 15. 6 and 7 show the operation panels in a state where the cover is closed and in an opened state, respectively, (A) is a front view and (B) is a side view. As shown in these drawings, a display unit 46 and an operation unit 48 are formed on the operation panel 45, and a cover 47 that can be opened and closed up and down is provided on the operation unit 48. Are formed with a hole 49A and a hole 50A for exposing the power switch 49 and the start button 50 even in the closed state. The operation unit 48 is provided with another operation button 51 that can be operated with the cover 47 opened.
Thus, by providing the openable / closable cover 47, it is possible to prevent erroneous operation due to unintended contact. The cover 47 can also cover the power switch and the start button.
[0045]
The entire lid member 31 of the rice inlet 30 can be seen through to some extent such as a transparent synthetic resin material such as polyvinyl chloride resin or polycarbonate resin, or polyethylene or acrylonitrile budadien resin (ABS). It is preferable to form with a semitransparent synthetic resin material.
According to such a configuration, since the operator can visually recognize the inside of the rice washing container 14 with the lid member 31 closed, troubles such as double throwing of rice can be prevented in advance. It can be discovered when something abnormal happens.
[0046]
When the lid member 31 is formed of a material that cannot be seen through, it is preferable to form a see-through window 31A made of a transparent or semi-transparent synthetic resin, for example, at the center of the lid member 31 as shown in FIG. . In this case, since the range of selection of the material of the lid member 31 is increased, it is possible to use a material excellent in sufficient strength, scratch resistance, contamination resistance, and the like.
[0047]
Thus, in the above embodiment, since there is no rice throwing hopper in front of the drive mechanism housing portion 15, the level position of the operation panel 45 can be lowered by the absence of the rice throwing hopper. Therefore, the display unit 46 of the operation panel 45 on the front surface of the drive mechanism housing unit 15 can be reliably recognized, and the operation unit 48 can be easily and reliably operated. It can be completely prevented.
[0048]
Further, in the above rice washing apparatus, water supply means including a water supply control valve and a flow rate sensor are accommodated in the drive mechanism accommodating portion 15, so that the degree of freedom of configuration in the water supply means is large. For example, unlike the case where the rearward region of the rice washing container 90 in FIG. 15 is arranged vertically along the support 82, the flow rate sensor can be arranged horizontally, which improves the weighing accuracy, Appearance is also good.
[0049]
  In the rice washing apparatus of the above embodiment, since the front area of the upper end opening of the cone-shaped rice washing container 14 is the rice inlet 30 as it is, the height direction required for the rice washing container 14 itself.ofThe length may be small and a rice hopper is unnecessary, and therefore the level position of the rice discharge means 20 can be increased while lowering the level position of the rice input port 30 as described above. .
[0050]
As a result, the level position of the upper surface of the rice-washing container receiving plate 18 on which the rice-washing receiving container 100 should be placed can be increased. Specifically, in the example of FIG. 1, the distance f from the floor surface FL to the upper surface of the rice-washing container receiving plate 18 can be about 500 mm, so that a heavy inner pot containing rice and water can be used. Workability, such as arrangement | positioning or movement of such a rice washing receiving container 100, can be improved significantly.
On the other hand, in the conventional rice washing device shown in FIG. 15, the position of the lower end of the rice discharging means 96 is at a low level due to the level position of the rice input port. The height e of the mounting portion 83 was about 440 mm, and the workability was low.
[0051]
In the rice washing apparatus of the present invention, the level position of the rice washing receiving container placing plate 18 is preferably variable. By comprising in this way, according to actual various working conditions, the level position of the rice-washing receiving container mounting plate 18 can be made the optimal height for work. For example, as shown in FIGS. 8 (a) to 8 (c), when the height of each of the rice washing receptacles 100A to 100C is different, the level of the rice washing receptacle receiving plate 18 is accordingly changed. The position can be changed.
[0052]
Specifically, as shown in FIG. 9, in each of the left and right support columns 12, mounting plate mounting holes 55 are provided at several level positions (five level positions in the example in the figure) at different heights. Two pieces are drilled forward and backward, and both side portions of the base end side portion of the rice-washing receiving container placing plate 18 are fixed to the front and rear portions by bolts. Therefore, by selecting the level position of the mounting plate mounting hole 55 to be mounted, the rice washing receiving container mounting plate 18 can be installed at the target level position. In this case, it goes without saying that the number of level positions where the mounting plate mounting hole 55 is formed, the actual height, and the like can be changed as required.
[0053]
In addition, the washing plate receiving plate 18 is supported in a state in which the height thereof is variable by other means, not by the means for forming the loading plate mounting hole 55 as described above at a plurality of level positions. Can be fixed.
[0054]
The rice washing apparatus of the above Example 1 does not have a rice cooking means, and puts the washed rice discharged from the rice discharging means and the weighed rice cooking water into a rice washing receiving container such as an inner pot, and separate rice cooking means. Although it is used when cooking rice, this invention is not limited to this, It is also possible to set it as the structure which mounted the rice cooker instead of the rice-washing receiving container.
[0055]
A drainage box 42 connected to a drainage pipe 41 extending from the chamber 40 at the lower end of the rice washing container 14 includes washing sewage separated from the rice by the drainage pipe 41 and the overflow water discharge part 36 described above (see FIG. 3). It is a relay means for joining the overflow washing sewage from and discharging it to the drainage part outside the apparatus. The drainage box 42 is provided with a valve mechanism (not shown) required for storing water in the rice washing container 14. However, in order to maintain the function of the valve and drainage, the drainage box 42 is necessary. It is necessary to open the front door 43 and perform cleaning or repair.
[0056]
In the rice washing apparatus described above, as shown in FIG. 10 (a), the drainage box 42 is based on the lateral direction of the apparatus (the direction in which the operation panel 45 extends, the direction perpendicular to the paper surface of FIG. 1) (0 degree). Is positioned in the angle region of 135 degrees in the horizontal plane with respect to the front (the left side in FIG. 1) as the reference (0 degree). .
Here, the arrangement position of the drainage box 42 should just be arrange | positioned in the angle area | region of 105-140 degree | times on the basis of a front direction, and it is preferable that it is especially in the angle area | region of 120-135 degree | times. Since the left and right directions may be any as long as they are within this angle region, they can be selected according to the actual situation.
[0057]
According to the configuration in which the drainage box 42 is disposed at such a rear position, for example, as shown in FIG. 10 (b), the problem that occurs when the drainage box 42 is disposed in a state of protruding in the lateral direction. Is resolved. Specifically, when the rice-washing receiving container 100 is carried in and out, an accident that collides with the drainage box 42 and damages the water-washing container 42 or spills water in the rice-washing receiving container 100 can be reliably avoided.
On the other hand, in the conventional apparatus of FIG. 15, the drainage box 86 is arranged in the rear region of the rice washing container 90, but in such a configuration, it is very difficult to clean and repair the drainage box, It may not be possible.
[0058]
In the rice washing apparatus of the present invention, as shown in FIG. 11, when the lid member 31 that opens and closes the rice inlet 30 is in a closed state, the lid member 31 is supported along a horizontal plane, thereby The upper surface of the packaging bag can form a temporary placement surface for the rice package P in which rice is filled in the packaging bag, which is very convenient in actual work.
Alternatively, the ceiling plate 15A of the drive mechanism housing portion 15 may be in a state of extending in the horizontal direction so that the temporary placement surface of the rice package P is formed by the upper surface thereof.
[0059]
In these cases, it is preferable to form a low ridge edge on the outer peripheral edge of the lid member 31 or the ceiling plate 15A of the drive mechanism housing portion 15, thereby making the support of the rice package P stable. it can.
[0060]
