Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a weighed rice bite and a weigh adjuster for a weighed rice bite. More specifically, a weighing rice meter having a weighing unit for weighing a certain amount of rice stored in the rice storage room, and an operation means for operating the weighing unit, and for changing the amount of measurement by the weighing unit. It relates to the weighing adjuster.
[0002]
[Prior art]
There are various weighing methods in today's weighing rice bins, but basically, a weighing space that receives a certain amount of rice falling through a pit provided at the bottom of the rice storage room, such as a weighing mass, A measuring section including means for opening and closing the dropping opening of the measuring space, and an operating means such as a take-out lever linked to the measuring section, and when the operating means is not operated, the drop opening is opened and the measuring space is opened. When the operation means is pressed, only the rice in the weighing space is dropped.
[0003]
The amount of this measuring space (weighing mass, etc.) is normally set to 1 unit (about 180cc), and the water scale of the rice cooker is also displayed in units corresponding to one unit of rice. If you read the scale according to the amount of rice weighed, the amount of water will be optimal.
[0004]
[Problems to be solved by the invention]
Among the rice that has recently been marketed, there is so-called non-washed rice in which rice bran is removed from conventional white rice. This washing-free rice is about 5% more than conventional white rice as the weight even if it is a weighing space of the same volume as the rice cake is removed, so the appropriate ratio of rice to water when cooking this is The water needs to be increased by about 5% compared to normal white rice. To do so, the amount of rice should be as measured by the measuring rice vat and the amount of water should be slightly higher than the scale of the rice cooker, or the amount of rice should be adjusted instead of matching the amount of water to the scale of the rice cooker. It is necessary to make adjustments such as 5% reduction from the amount measured by the measuring rice bottle. Naturally, if this adjustment is not made, the amount of water is insufficient with respect to the amount of rice, so that hard rice is cooked.
[0005]
However, in order to make such an adjustment accurately, it is necessary to properly measure 5% increase or 5% decrease with rice or water using measuring cups, etc. There is no other way but to get it done.
In any case, after all, the original function of accurate weighing, which is the greatest advantage of weighing rice, cannot be fully utilized.
[0006]
In order to solve this problem, for example, it is considered that the measuring unit of the measuring rice bin has a function of adjusting the amount of the measuring space, or a scale for washing-free rice is added to the water amount of the rice cooker. However, the former is a very complicated solution because the structure of the weighing section becomes extremely complex and the cost of rice is soaring, and those who have existing weighing rice must replace their rice. Must not. Moreover, even in the latter case, the existing rice cooker must be replaced, and there is a risk that the handling will be confused as the types of water scales increase.
[0007]
The present invention has been made in view of the above-described problems, and selectively changes the amount of rice entering the measuring space of the measuring unit without changing the structure of the measuring unit, the take-out lever, or the like. It is an object of the present invention to provide an innovative weighing rice bin that can be appropriately weighed according to the type of rice.
In addition, the present invention can selectively change the amount of rice entering the weighing space of the weighing unit simply by attaching it to an existing weighing rice bin that is configured to perform weighing corresponding to conventional white rice. An object of the present invention is to provide a weighing adjuster for measuring rice bottles that can be appropriately weighed according to the type of rice.
[0008]
[Means for Solving the Problems]
  to this end,Of the present inventionThe weighing rice bin has a cabinet having a rice storage chamber provided with a mouthpiece at the bottom, a weighing space for containing a certain amount of rice falling through the mouthlet, a mouthlet opening / closing means for opening and closing the mouthlet, A weighing unit having a means for opening and closing a dropping port for dropping rice, a weighing unit operating means for operating the weighing unit, and a detachable attachment to the weighing unit or the weighing unit operating means, etc. It is equipped with a weighing adjuster that reduces the amount of rice entering.
[0009]
Therefore, according to the present invention, when normal rice such as white rice is stored, it is used without being equipped with a weighing adjuster, so that it is weighed according to the scale of the weighing space, and is not washed rice. If the same amount of rice that weighs more than normal rice is stored, attach a weighing adjuster to reduce the effective amount in the weighing section by the amount corresponding to the weighing adjuster. Since it is possible to use it selectively, it is possible to adjust the amount of water per unit of white rice as it is without washing the rice that has been weighed with the rice bottle and further adjusted with a measuring cup. Of water.
[0010]
Moreover, since the weighing adjuster in the present invention is a structure that is detachably attached to the weighing unit or the weighing unit operating means in the rice vine body, the main body structure of the weighing rice jar does not require any special treatment. For existing weighing rice bins that are configured to perform weighing corresponding to conventional white rice, the effective amount by the weighing unit of the rice bottle can be selectively set, and an appropriate amount according to the type of rice can be selected. Weighing can be performed.
[0011]
  The form of the weighing adjuster according to the present invention can be detachably mounted without modifying or disassembling the weighing unit, the weighing unit operating means, the cabinet, or the like.1And claims9If it is configured to be mounted using the weighing unit operating means as in this invention, anyone can easily attach and detach the weighing adjuster.
[0012]
  That is, the claim1The measuring rice bit listed inA cabinet having a rice storage chamber provided with a dropper at the bottom, a weighing space for containing a certain amount of rice falling through the dropper, a dropper opening / closing means for opening and closing the dropper, and dropping the rice in the weighing space A weighing unit having means for opening and closing the dropping port; a weighing unit operating unit for operating the weighing unit; and a weighing adjuster that is detachably attached to the weighing unit operating unit to reduce the amount of rice entering the weighing space. The weighing unit operating means protrudes outward through the lever protruding port of the cabinet and when the operated portion is at an initial position, the dropping port opening / closing means fully opens the dropping port and moves in the operation direction when the operation is taken out. A take-out lever that interlocks with the weighing unit and a spring that urges the take-out lever toward an initial position so that the drop opening is opened when it is tilted; The spacer is attached to the operated part of the take-out lever or the lever projecting port in a detachable manner and has a spacer, and when the measuring adjuster is installed, the spacer unit is located between the edge of the lever projecting port and the take-out lever. The return of the dropper opening / closing means to the dropper opening direction is prevented at a position where the dropper is partially opened, thereby reducing the amount of rice entering the weighing space.It is characterized by this.
  The weighing rice bit according to claim 2 is the weighing rice bit according to claim 1, wherein the weighing unit has the weighing position in which the dropping port is fully opened by directing the opening toward the dropping port and the opening substantially downward. It is characterized by comprising a weighing mass that is moved between the directing drop position.
[0013]
  Claim9The measuring adjuster for the measuring rice container described in 1) includes a cabinet having a rice storage chamber provided with a dropper at the bottom, a weighing space in which a certain amount of rice falls through the dropper, and a dropper opening / closing means for opening and closing the dropper. A weighing unit having a means for opening and closing a dropping port for dropping rice in the weighing space, and when the operated part protrudes outward through a lever protruding port of the cabinet and comes to an initial position, the dropping port opening and closing unit Is equipped with a take-out lever that interlocks with the weighing unit so that the drop-out port opens when the drop-out opening is fully opened and is tilted in the operation direction during take-out, and a spring that biases the take-out lever toward the initial position. A weighing adjuster for a rice bin, which is detachably attached to the operated part or lever protruding port of the take-out lever and has a spacer part. In this state, the spacer portion is sandwiched between the operated portion and the edge of the lever protruding port, and the return to the dropping port opening direction of the dropping port opening / closing means is prevented at the position where the dropping port is left partially opened, As a result, the amount of rice entering the weighing space is reduced.
[0014]
  Claim1Weighing rice bites or claims9If the weighing adjuster is not attached to the take-out lever or lever projection, the take-out lever can return to its original initial position. The mouth opening / closing means is also returned to the position where the dropper is opened to the original open state, and the original bulk of rice falls into the measuring space, and the measuring adjuster is taken out and attached to the lever or lever protruding port. In this state, since the return to the initial position of the take-out lever is blocked halfway by the spacer part, the dropper opening / closing means of the measuring part is also blocked before the position where the dropper is opened to the original open state. As a result, the amount of rice falling into the weighing space is small enough not to fully open the pit.
[0015]
  Therefore, if the size of the spacer is set so that the amount of weighing in the state where the outlet is not opened and fully opened is suitable for, for example, washing-free rice, when the weighing adjuster is attached Weighing is carried out with an amount suitable for washing-free rice, and when the weighing adjuster is not attached, weighing with an amount suitable for general white rice is carried out. In particular, this claim1And9Since the measuring adjuster is attached to the take-out lever or the lever projection opening, it can be attached even after the rice is stored in the rice storage chamber, so that it is not necessary to select the time of attachment.
[0016]
  These claims1And9The spring according to the invention may be incorporated in a form in which the take-out lever is directly urged, or may be incorporated in a form in which the operation member of the measuring unit, for example, the measuring mass is directly urged. In addition, there are various means for attaching this measuring adjuster. For example, the type to be attached to the operated portion of the take-out lever is, for example, a main portion that covers the operated portion, a spacer portion, and a take-out lever at least from below. So-called one-touch attachment / detachment can be realized by forming the engaging latching claw to be integrally formed of plastic. In addition, as a type to be mounted on the lever protrusion, the clip part that elastically sandwiches the edge of the lever protrusion and the spacer part that protrudes toward the operated part of the take-out lever are integrally formed of plastic. If so, this can also be achieved by so-called one-touch attachment / detachment.

And the direction toward the lower left is the left side.) Is provided only in the portion corresponding to the rice storage chamber 5, and the take-out chamber 6 has an open front surface.
The portion of the front wall 7 that is vertically elongated at the position near the lower end is a recess 8 that is recessed to a certain extent so as to protrude into the rice storage chamber 5, and a horizontally-long rectangular lever on the back wall of the recess 8. A protruding port 8a is formed.
In the take-out chamber 6, a take-out case 9 having a box shape with an open top is accommodated so as to be freely put in and out, and the rice in the rice storage chamber 5 is taken out into the take-out case 9 for each amount measured by a rotary weighing mass described later. It is.
[0021]
[A-2. (Partition plate and dropper) (Figs. 1-3, 5, etc.)
The partition plate 4 has a bottom top portion 11 at a portion slightly ahead of the middle in the front-rear direction, and an intermediate portion in the left-right direction of the bottom top portion 11 serves as a drop port 11a.
Measuring mass support walls 15 and 16 that are parallel to each other protrude from the front and rear ends of the bottom top portion 11 in a drooping manner, and a measuring auxiliary wall 18 and a stopper 19 are provided across the weighing mass support walls 15 and 16. Yes. The measuring auxiliary wall 18 is a part that demarcates a measuring space in cooperation with a rotating measuring mass, which will be described later. The measuring auxiliary wall 18 has a substantially horizontally inverted shape extending in the front-rear direction. The arc is continuous and the arc is centered on the shaft support holes 15a and 16a formed in the weighing mass support walls 15 and 16, and the lower end is located slightly to the left of the shaft support holes 15a and 16a. It's over.
The stopper 19 extends along the right edge of the drop port 11a from below.
[0022]
Further, from the front side portion of the partition plate 4, lever support walls 21 that face each other in parallel protrude from the partition plate 4, and the lever support shaft 22 is attached in a horizontal posture so as to span the lever support walls 21. Yes.
[0023]
[A-3. Rotating weighing mass] (FIGS. 1-3, 5, etc.)
Reference numeral 31 denotes a rotary weighing mass. The rotary weighing mass 31 has a horizontally long, generally cylindrical shape with both front and rear surfaces closed, and the peripheral wall 33 has a substantially C-shaped cross section so that an opening 39 is provided in a part of the peripheral surface. Yes.
The peripheral wall 33 is seen in a cross section from the front side (see FIG. 5), and extends in an arc shape in a range extending from the one end 33a in the clockwise direction by about 160 ° in the clockwise direction. The portion 33b is formed in a substantially flat plate shape and is bent inward, and a narrow sheet-like sweeper 35 extending in the front-rear direction is attached to the tip of the other end portion 33b.
The rotary weighing mass 31 is formed with a circular protrusion 34 protruding rearward at the center of the front plate, and the protrusion 34 is formed with a coupling hole 34a having a square cross section with an open front surface. Further, a measurement position stop claw 37 and a drop position stop claw 38 are provided so as to protrude from the outer peripheral edges of the front plate and the rear plate.
[0024]
Reference numeral 41 denotes a weighing mass support shaft, and a bevel gear 43 is attached to the front end portion thereof. The bevel gear 43 is integrally formed with a boss 44 projecting rearward from the bottom surface of the cone, and the rear half of the boss 44 is a connecting portion 44a having a square cross section.
The rotating weighing mass 31 is rotatably supported by the weighing mass support walls 15 and 16 via the boss 44 of the bevel gear 43 and the weighing mass support shaft 41. That is, in a state where the rotary weighing mass 31 is placed between the weighing mass support walls 15 and 16, the through holes and the support walls 15 and 16 formed at the center of the front and rear walls of the rotary weighing mass 31 are provided. The weighing mass support shaft 41 is passed through the shaft support holes 15a and 16a, the front end portion of the weighing mass support shaft 41 is passed through the through-holes of the bevel gear 43 and the boss 44, and the connecting portion 44a of the boss 44 is passed through the rotating weighing mass 31. Is fitted into the coupling hole 34a.
[0025]
Accordingly, the rotary weighing mass 31 is arranged so as to be freely rotatable under the drop port 11a in a state of rotating integrally with the bevel gear 43.
As shown by a solid line in FIG. 5, the rotation range of the rotary weighing mass 31 includes a measuring position where the measuring position stop pawl 37 is in contact with the lower end of the measuring auxiliary wall 18, and a dropping position as indicated by a two-dot chain line in FIG. The stop claw 38 is regulated between the dropping position where it comes into contact with the stopper 19.
[0026]
In the state where the rotary weighing mass 31 is at the weighing position, as can be seen from FIG. 5, the positions of the one end 33a of the peripheral wall 33 and the right edge of the drop port 11a are aligned, and the sweeper 35 is placed in the weighing auxiliary wall 18. It is in close proximity or lightly in contact with the armpit position from the middle part of the inner peripheral surface. Therefore, in this state, a part of the opening 39 of the rotary weighing mass 31 is directed to the whole of the dropping port 11a, so that the dropping port 11a is fully opened, and other than the dropping port 11a is connected to the rotary weighing mass 31 and the weighing assistance. A substantially cylindrical measuring space 46 (see FIGS. 5 and 9) closed with the wall 18 is defined.
Therefore, when rice remains in the rice storage chamber 5, the rice falls into the weighing space 46 when the rotary weighing mass 31 comes to the weighing position.
The size of each part is set so that the capacity of the measurement space 46 is about 1 (180 cc).
[0027]
Further, when the rotary weighing mass 31 rotates from the measuring position toward the dropping position, the peripheral wall 33 closes the dropping port 11a and drops when one end 33a thereof is aligned with the left edge of the dropping port 11a. The mouth 11 a is completely closed, and at the same time, the tip of the sweeper 35 is disengaged from the lower end of the measuring auxiliary wall 18. Therefore, when rice is contained in the measurement space 46, the dropping of the rice starts from this point. When the rotary weighing mass 31 reaches the dropping position, the sweeper 35 is greatly separated from the lower end of the weighing auxiliary wall 18 to the right side, and the opening 39 of the rotary weighing mass 31 is lowered with the same size as the dropping port 11a. Since it faces, the rice that has entered the weighing space 46 is completely dropped into the take-out case 9.
[0028]
[A-4. (Lever) (FIGS. 1-3, 7, 8)
Reference numeral 51 denotes a take-out lever. The take-out lever 51 is for rotating the rotary weighing mass 31, and has a structure in which an operated portion 53, an interlocking arm 54, a cylindrical fulcrum boss 55, and the like are integrally formed of plastic.
The operated portion 53 has a thin box shape, and the interlocking arm 54 projects rearward from the rear end of the right side wall, and a columnar fulcrum boss 55 is horizontally extended to the left from the intermediate portion of the interlocking arm 54. A fan-like gear portion 56 is formed on the left side surface of the rear end portion of the interlocking arm 54 so as to project from the left side. The teeth of the gear portion 56 are arranged on an arc centered on the axis of the fulcrum boss 55.
The lower portion of the back wall of the operated portion 53 extends to some extent below the remaining portion to form a hidden flap 53a, and is inclined slightly rearward from the rear end of the upper surface portion of the operated portion 53. Another hidden flap 53b extends.
[0029]
The take-out lever 51 is rotatably supported by the lever support shaft 22 when the lever support shaft 22 is inserted into the fulcrum boss 55, and the gear portion 56 is positioned on the right side of the bevel gear 43. To mesh. As a result, the rotary weighing mass 31 and the take-out lever 51 are coupled to each other so that the rotation range of the take-out lever 51 is restricted by the rotation range of the rotary weighing mass 31. That is, the rotation range of the take-out lever 51 includes an initial position that is a position when the rotary weighing mass 31 comes to the weighing position, and a push-down completion position that is a position when the rotary weighing mass 31 comes to the dropping position. Be regulated during. This initial position is a position where the operated portion 53 is inclined slightly upward from the horizontal as shown by a solid line in FIG. 3, and the pressed down position is operated as shown by a two-dot chain line in the same figure. This is a position where the portion 53 is inclined slightly downward from the horizontal.
[0030]
The take-out lever 51 is biased by a torsion spring 58 in the counterclockwise direction as viewed from the left. Therefore, unless the take-out lever 51 is pushed in the clockwise direction, the lever 51 is always held at the initial position, and accordingly, the rotary weighing mass 31 is held at the weighing position. In addition, when the take-out lever 51 is pushed downward from this state, the rotary weighing mass 31 is rotated toward the drop position, and at the same time the take-out lever 51 reaches the push-down completion position. Thus, it is prevented from rotating downward.
[0031]
When the take-out lever 51 is pushed down while rice is in the weighing space 46, the rice is dropped into the take-out case 9, and when the push-down to the take-out lever 51 is released from this state, the take-out lever 51 is moved to the initial position. And the rotary weighing mass 31 is returned to the weighing position, and the drop port 11a is fully opened.
[0032]
Nearly the entire operated portion 53 of the take-out lever 51 protrudes forward from the lever protrusion 8a.
The lever protrusion 8 a of the cabinet 3 is somewhat larger than the length of the operated portion 53 in the vertical direction in order to allow the above-described movement of the take-out lever 51, and has a certain gap below or above the operated portion 53. However, this gap is hidden behind by the hidden flaps 53a, 53b of the take-out lever 51.
As can be seen from FIG. 3, this gap is also left on the upper side of the operated portion 53 by the width w when the takeout lever 51 is in the initial position.
[0033]
[B. First Form of Weighing Adjuster] (FIGS. 6 to 8)
Reference numeral 61 denotes a weighing adjuster according to the first embodiment. This measuring adjuster 61 is used by being attached to the take-out lever 51 as required, and the main portion 62, the spacer projection 63, the hooking claw 64 and the locking claw 65 are integrally formed of plastic. It has a structured.
[0034]
The main portion 62 is formed in a box shape having an open bottom surface and a back surface, and is sized so as to be able to fit almost the front half of the operated portion 53 of the take-out lever 51 from the rear end of the top surface portion. Most of the part extending horizontally rearward is a spacer protrusion 63 shaped like a plateau that rises upward with respect to the remaining part. The length H (see FIG. 6) of the spacer protrusion 63 is about twice the gap w.
A hooking claw 64 having an inverted V shape when viewed from the side is formed on the rear side of the spacer projection 63, and small locking claws 65 are formed from the lower ends of the middle portions of the left and right side walls of the main portion 62. Projecting toward each other. The left and right side walls of the main portion 62 can be bent in the left-right direction relatively easily by forming a window for stealing meat at a portion above the locking claw 65.
[0035]
The measuring adjuster 61 is attached to the take-out lever 51 as shown in FIGS. That is, when the main hook 62 is pushed down a little strongly so as to cover the operated portion 53 while being hooked on the hidden flap 53 b on the upper side of the take-out lever 51, the locking claw 65 is moved to the side wall of the operated portion 53. Engage to hold it from below. As a result, the weighing adjuster 61 is attached to the operated portion 53 of the take-out lever 51.
Note that this attachment can be performed without removing the front wall 7 if the take-out lever 51 is pushed down to the push-down completion position.
[0036]
When the weighing adjuster 61 is mounted in this manner, the weighing position of the rotary weighing mass 31 is slightly shifted as shown in FIG. 9 without pressing the take-out lever 51, and the drop port 11a is about one third. It will be left unopened. That is, when the weighing adjuster 61 is attached to the take-out lever 51, as shown in FIG. 8, the spacer projection 63 is located between the operated portion 53 of the take-out lever 51 and the upper edge of the lever protrusion 8a. When the take-out lever 51 returns toward the initial position, the spacer protrusion 63 comes into contact with the upper edge of the lever protrusion 8a before it reaches the initial position, thereby preventing further movement. The position at which the take-out lever 51 is blocked in this way is a position that leaves the same distance as the gap w described above up to the original initial position. Accordingly, in this case, the rotary weighing mass 31 is also prevented from returning to the original weighing position, and as shown in FIG. 9, the peripheral wall 33 waits at the corrected weighing position where the drop port 11a is left open by about one third. become.
[0037]
[C. Second form of measuring adjuster] (FIGS. 10 to 13)
71 shows the measurement adjuster which concerns on a 2nd form. The measuring adjuster 71 is used by being mounted in the rotating measuring mass 31 as necessary, and has a structure in which a main portion 72 and two mounting arms 73 and 73 'are integrally formed of plastic. It has become.
[0038]
The main portion 72 has a strip shape that is long in the front-rear direction, and its cross section is bent in an arc shape. The curvature of the arc is the arc-shaped portion of the peripheral wall 33 of the rotary measuring mass 31. It is almost the same as the curvature of the inner peripheral surface. The length in the front-rear direction is substantially equal to the distance between the front and rear walls of the rotary weighing mass 31.
An extremely small ridge 72a extending in the front-rear direction is provided at the center of the surface of the main portion 72 that swells, and the cross section of the ridge 72a has an isosceles triangle shape.
A rectangular finger hooking hole 72b is formed on both sides of the protrusion 72a.
[0039]
The two mounting arms 73 and 73 'are both formed in a flat plate bent in a narrow shape, projecting in parallel from the front and rear ends of the main portion 72, and on the side edges around the bent portion of the dog-leg shape. Semicircular cutouts 73a and 73'a are formed. The centers of these notches 73a and 73'a are coaxial with each other, and the notch 73a of the front mounting arm 73 is formed with a diameter substantially the same as the outer diameter of the projection 34 of the rotary weighing mass 31, and the rear side A notch 73 ′ a of the mounting arm 73 ′ is formed with a diameter approximately the same as the thickness of the weighing mass support shaft 41.
[0040]
The weighing adjuster 71 is mounted in the rotating weighing mass 31 as shown in FIGS. That is, as shown by a two-dot chain line in FIG. 11, when the weighing adjuster 71 is gripped by placing a fingertip on the finger-holding hole 72b and inserted into the rotary weighing mass 31 through the drop port 11a, the mounting arms 73, 73 ' Overlaps with the front and rear walls of the rotary weighing mass 31, respectively, the rear notch 73'a engages with the weighing mass support shaft 41, and the front notch 73a engages with the projection 34, and simultaneously with this engagement, The swelled surface of the portion 72 is located on the extension of the arc of the peripheral wall 33 of the rotary weighing mass 31 or at a position slightly inside it. From this state, when the side edge of the finger hooking hole 72b and the side edge of the main portion 72 are pushed to the right, the measuring adjuster 71 rotates around the measuring mass support shaft 41, and the main portion 72 is shown by a solid line in FIG. As shown in FIG. 2, it fits on the peripheral wall 33 so as to overlap from the inside.
[0041]
This rotation is performed until the left edge of the main portion 72 is aligned with the one end 33 a of the peripheral wall 33. At this time, the protrusion 72 a is pressed against the peripheral wall 33 by being relatively pressed by the inner peripheral surface of the peripheral wall 33. As a result, the weighing adjuster 71 is mounted in a form that is press-fitted between the peripheral wall 33 of the rotary weighing mass 31 and the support shaft 41.
[0042]
When the measurement adjuster 71 is mounted in this manner, the effective volume of the measurement space 46 is reduced by the volume of the measurement adjuster 71. The volume of the metering adjuster 71 is designed so that the effective volume of the metering space 46 is reduced by approximately 5% from the original volume.
Therefore, when this weighing adjuster 71 is attached, 5% less rice is weighed compared to the state where it is not attached.
[0043]
[D. How to use etc.)
Next, how to use the weighing rice container 1 and the weighing adjusters 61 and 71 will be described.
[D-1. Normal rice weighing] (Figure 5)
When rice that is not washed is stored in the rice storage chamber 5, the measuring adjusters 61 and 71 are used without being attached. Therefore, in this case, when the take-out lever 51 is not pushed, the rotary weighing mass 31 stands by at the original weighing position, so that exactly one rice is contained in the weighing space 46 as shown in FIG. An amount of rice is taken out into the take-out case 9 each time the take-out lever 51 is pushed down.
[0044]
[D-2. (Measurement of wash-free rice)
When storing unwashed rice in the rice storage chamber 5, the weighing adjuster 61 or 71 is attached for use. The weighing adjuster 61 may be mounted after the rice is stored in the rice storage chamber 5, but the weighing adjuster 71 is mounted before the rice is stored.
[0045]
[D-2-a. When using the first weighing adjuster] (FIGS. 8 and 9)
When the weighing adjuster 61 is mounted, as described above, when the rotary weighing mass 31 returns to the weighing position, it can be stopped at the corrected weighing position where the drop port 11a is left open by about one third. As shown, it becomes difficult for rice to fall immediately below the unopened portion, and an empty space 71 is inevitably generated here.
The height H of the spacer protrusion 63 of the measuring adjuster 61 is set so that the capacity of the empty space 71 is approximately 5% of the measuring space 46.
[0046]
Therefore, when the weighing adjuster 61 is mounted, an amount of rice that is less than about 5% per unit falls in the weighing space 46, and this amount of rice falls into the take-out case 9 each time the take-out lever 51 is pushed down. It is taken out.
Thus, when washing-free rice is stored, if the weighing adjuster 61 is used, the amount is about 5% less than one unit, but the weight of one unit is automatically weighed. Therefore, the amount of water should be considered with the same standard as in the case of non-washed rice.
[0047]
[D-2-b. When using the second weighing adjuster] (FIGS. 11 and 13)
When the weighing adjuster 71 is attached, as described above, the effective volume of the weighing space 46 is reduced by the volume of the weighing adjuster 71. % Of rice is weighed, and this amount of rice is dropped into the take-out case 9 each time the take-out lever 51 is operated. Therefore, in this case as well, the water level can be considered with the same standard as in the case of rice that is not washed.
[0048]
When removing the attached measuring adjuster 71, as shown in FIG. 13, a fingertip, chopsticks or the like are inserted from the dropper 11a and the lower ends 73b and 73'b of the mounting arms 73 and 73 'are pushed downward. The measuring adjuster 71 rotates and the main portion 72 of the metering adjuster 71 comes out about half of the drop opening 11a.
[0049]
