PROBLEM TO BE SOLVED: To solve such inconvenience that a user adjusts a water quantity of a household rice cooker by looking a scale attached to an inner wall, however, a boundary area between the scale and a water surface is curved and becomes a lens-like shape due to the surface tension and further the inside of a pot is dark.SOLUTION: At first, a desired amount of rice is cooked at a designated water quantity according to a scale of a pot, and the water level thereof is stored in a water level comparative measurement instrument 1 according to the present invention. When cooking the rice next, a user can manage the water quantity by looking the scale of the water level comparative measurement instrument 1, thereby capable of finely adjusting the water quantity compared with the rice cooking state of the previous day.SELECTED DRAWING: Figure 1

Description

    The present invention relates to a method and apparatus for comparing and confirming the amount of water in a household rice cooker.

    Rice cookers are home appliances that have evolved rapidly with the evolution of various sensors and microcomputers, but the judgment of whether or not to cook is still incomplete. That is, it is speculated that the first cause is that there are too many subjective factors and the evaluation method is ambiguous.

    The amount of water in household rice cookers that are currently on the market and in rice cookers that are actually used is mostly inconvenient, so that the scale of the inner pot is visually confirmed.

    In order to solve this inconvenience, a cap is provided at the top of the central shaft, a slide integrated with the floating float is passed through the shaft, numbers are written on the top of the shaft, and the float is placed in water. A rice cooking water meter that stops the water when a number goes into the window at the top of the slide, and allows you to see the desired amount of rice in the upper part of the rice cooker. (See Patent Document 1) has been proposed.

    The problem to be solved is that when the scale marked on the inside of the rice cooker of the rice cooker is visually confirmed, the boundary becomes a curved surface due to the surface tension of water and the scale itself becomes difficult to see. For example, when trying to increase the amount of water by 10% in a rice cooker having a diameter of about 18 cm, it is necessary to read the change in the water level of about 1 mm, which is difficult visually.

    The present invention uses a water level measuring device independent of the scale of the rice cooker, stores the water level at the previous rice cooking in the water level measuring device, and uses that as a reference to accurately determine whether the amount of water is large or small during the next rice cooking. It is characterized by comparative measurement.

    According to the present invention, the amount of water in a household rice cooker can be more precisely controlled. That is, it is because it became possible to memorize | store the water quantity most liked from the experience by own rice cooking result, ie, the water level at that time, in a rice cooker water level comparison measuring device, and to adjust to the water level precisely from the next time.

FIG. 1 is a sectional view of an embodiment according to claim 2 of the present invention.
The float 3 is provided with protrusions 3 ′ at eight places on the top and bottom, and can move freely inside the measuring instrument body 1. The protrusion 3 ′ prevents the float 3 and the measuring instrument body 1 from coming into close contact with each other due to the surface tension of water.

    The gauge plate 2 is provided with a slit in the longitudinal direction of the central portion, the lower end is joined to the float 3, and the upper side is combined through the measuring instrument top plate 1 '. The float 3 is prevented from falling off from the measuring instrument body 1 by a stopper 5, and an adhesion prevention hole 6 is provided at the lowermost end of the measuring instrument body 1. Without this hole, when the measuring instrument body 1 is erected in the rice cooker, it will be in close contact with the bottom of the rice cooker and water will not enter.

    The index 4 includes an arrow portion, a shaft, and a pressing washer, and is fixed so as to be movable by crimping the shaft through the slits of the gauge plate 2 from both sides. It is also possible to attach the shaft with a nut with a stepped screw.

The usage is as follows. First, water is added in the same manner as before, and the index 4 is moved by hand so that the arrow part of the index 4 of the water level comparison measuring instrument at this time coincides with the indication line of the measuring instrument top plate 1 '.
This operation is a water level record to a water level comparison measuring instrument, and it becomes possible to make the water level exactly the same as the previous time by looking at this index 4 at the time of the next rice cooking.

      If the cooked rice at the first cooking is soft or firm, the position of the index 4 is moved to determine the optimum position according to one's preference.

FIG. 3 is a sectional view of an embodiment according to claim 3 of the present invention.
The lever 7 is formed by joining a stainless steel wire and a disk portion having a hole at the center serving as a fulcrum. The power point portion of the lever 7 is brought into contact with the upper surface of the float 3 and the lever 7 is operated by a force that raises the float upward. The weight of the lever 7 is distributed so as to be lowered during normal times.

    The measuring instrument body 1 has a structure that is divided into two in the vertical direction, and is integrally assembled by screws, bonding, or the like. A height adjustment screw portion 9 having a circular cross section is provided below the measuring instrument body 1 and the height adjustment foot 10 is combined with a screw. The height adjustment foot 10 moves up and down by rotation, Adjust the height position of the float. The fine adjustment within 1 unit of rice is adjusted by the vertical movement by the rotation of the height adjusting foot 10. Moreover, the length of the height adjustment screw part 9 is made constant, and by preparing several types of lengths of the height adjustment feet 10, it is possible to cope with changes in the amount of rice cooked in units of 1 rice. That is, when 3 rice is cooked with a rice cooker, it is changed to the height adjustment foot 10 for 3 go. Usually, the amount of cooked rice in a general household is almost constant and there is no inconvenience.

    The float 3 has the same configuration as the float of claim 1. In this embodiment, it has a contact prevention protrusion 3 ′ and can be freely moved up and down within the inner surface of the height adjusting screw portion 9. The measuring instrument top plate 1 'has a slit on which the action point of the lever 7 protrudes and can freely move left and right. Marks and scales such as 0, +, and − are printed on the measuring instrument top plate 1 ′, and an arrow-shaped index is fixed to the tip of the lever 7. Since the action of the action point is a circular motion, a vertical distance is generated at the left and right positions and the central portion.

    Although it is effective to provide a cover for the measuring instrument top plate 1 'with a transparent material so that the index 4 is not deformed, it does not affect the explanation of the requirements of the present invention. Is omitted.

    The embodiment of the third aspect can enlarge the change in the water level. In this embodiment, the change in the water level of 1 mm is displayed as the change in the horizontal movement of the scale of 10 mm, which is very useful.

FIG. 5 is a sectional view of an embodiment according to claim 4 of the present invention.
A digital caliper is a type that measures the depth called a depth gauge, which is closest to the present embodiment, but it is an instrument that electronically measures the distance. In the case of the present embodiment, the digital caliper 1 includes a main scale 12, a slider 13 slidable in the longitudinal direction of the main scale 12, and a float 3 integrated therewith. The slider 13 includes a displacement sensor and an electronic circuit. A display 14 for displaying a detection value as a displacement measurement result is arranged on the upper surface of the float 3.

  The important point in this embodiment is the program until it is output to the display, but it is possible to memorize it after the switch is turned off with the water level once memorized as the zero point. In other words, if the normal electronic caliper is switched off, the zero point disappears and it will start over from the beginning, but in this embodiment, the position information at the time of the water level when the rice can be cooked well is fixedly stored as the zero point. Function.

  A program that can store a plurality of zero points is desirable. That is, it is desirable to memorize a plurality of zero points when cooking 3 go rice, like when cooking 2 go rice, so that it can be selected at the time of use. In use, if it is 3 go, the zero point information of 3 go is called, and whether the current water level is large or small relative to the water level is displayed.

    According to the present invention, the amount of water in a household rice cooker can be managed easily and accurately.
