Description

  The present invention relates to a weight measuring device that measures the weight of an object and calculates and displays an amount related to a specific component included in the measured object based on the measurement result.

  In the weight measuring apparatus, a relational expression between the weight of a specific type of object and the amount of the specific component included in the object is stored, and the amount of the specific component is calculated and displayed based on the measurement result of the weight of the object. There is a thing of the composition that made it possible.

  For example, Patent Document 1 describes a weight measuring device that measures the weight of food and calculates and displays the amount of food components from the measurement result. Specifically, there is a description of a technique for calculating the amount of heat from the weight of rice.

  By the way, normally, a sticky object such as rice is put on a weight measuring device in a state in which it is put in a container. In Patent Document 1, the weight of the rice is measured by subtracting the weight of the container, so-called taring. From the result, it is estimated that a technique for calculating the amount of heat is provided.

JP 2013-140092 A

  Although there is no direct description in Patent Document 1, in the technique of taring and calculating and displaying the component amount from the measurement result, if the measurement object is removed from the weight measurement device for each container, no special processing is required. Normally, the calculation result of the component amount is displayed as a negative number.

  However, as described above, the amount of the specific component is displayed as a negative number based on the weight of the container that is not of the kind to be applied in the relational expression between the stored weight and the amount of the specific component. Thus, the amount of the specific component is calculated. In addition, the amount of the specific component included in the measurement object cannot be a negative value.

  As described above, the amount of the specific component contained in the measurement object cannot be negative. Therefore, it is not correct that the amount of the specific component is displayed as a negative number in this way. The user of the weight measuring device is confused.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a weight measuring apparatus that solves the above-described problems, displays information that is not possible in practice, and does not confuse the user.

  The weight measuring apparatus according to claim 1 of the present invention includes a placement unit for placing a measurement object, a measurement unit for measuring the weight of the measurement object placed on the placement unit, and a weight of the measurement object. And a display unit that displays the calculation result of the amount of the specific component contained in the measurement object, and the measurement result of the weight of the measurement object is displayed on the display unit by subtracting the weight of the container of the measurement object. When the specific component amount calculation is performed together with the tare subtraction process, the specific component amount calculation that calculates the amount of the specific component based on the measurement result of the weight of the measurement object, and the tare subtraction process, When the calculation result of the amount of the specific component is a negative number, the display unit displays zero as the display of the amount of the specific component and displays the weight measurement result of the measurement unit as a negative number It is characterized by having a control unit that performs processing

  When the weight of the measurement object is subtracted by subtracting the weight of the container and the amount of the specific component is calculated based on the measurement result, if the measurement object is removed from the placement part for each container, the measurement result of the quantity is calculated. Although it is a negative number, according to the weight measuring device of the present invention, even if the amount of the specific component is a negative number in calculation, without an unclear indication that the amount is a negative number, By displaying that an inappropriate calculation result is displayed, it is possible to prevent the user from being confused.

  Reference numeral 7 denotes a control unit (microchip), which is weight calculation upon receiving measurement data from the measurement unit 6, tare processing, display processing for sending display data to the display unit 3, and rice mode. Based on the measured weight of rice (white rice), it has a function to perform weight / heat amount and carbohydrate amount conversion calculation to convert to calorie and carbohydrate amount, and controls the mode switching by the changeover switch 5 in an integrated manner .

  Moreover, the control part 7 is provided with the memory function which stored the relational expression of the weight of rice (white rice), calorie | heat amount, and the amount of carbohydrates as a computing equation.

  The display unit 3 includes a liquid crystal display that displays the measured value (g) of the weight and the calculated values of the calorie (kcal) and the carbohydrate amount (g) by the calculation of the weight / heat amount and the carbohydrate amount conversion in the control unit 7.

  Hereinafter, the operation of the scale mode and the rice mode will be described.

  First, the operation of the balance mode will be described with reference to a flowchart showing the entire processing procedure of FIGS. 4 and 5 and a series of flowcharts of the usage state of FIG. In the scale mode, only the weight of the object is measured. Further, (A), (B), (C), and (D) in FIG. 4 are respectively connected to (A), (B), (C), and (D) in FIG.

  As shown in FIG. 6A, when the switching button 5 is pressed, the control unit 7 switches between the balance mode and the rice mode (S1). Then, as shown in FIG. 6B, when the power button 4 is pressed, the power is turned on (S2), and weighing in the balance mode is performed (YES in S3, S4). In a state where nothing is placed on the placement unit 1, zero (0) is displayed on the display unit 3.

  As shown in FIG. 6C, when taring and measuring the weight (YES in S5), first, only the container A is placed on the placing portion 1 (S6). Then, the weight of the container A is converted into data by weight calculation in the control unit 7, and the data is displayed and displayed on the display unit 3 (91.5 g in this example). Next, as shown in FIG. 6D, when the power button 4 is pressed (S7), a taring process is performed in the control unit 7, and the weight measurement value is displayed by subtracting the weight of the container A ( In this case, since there is no content, 0g) is performed (S8).

  As shown in FIG. 6E, for example, when a part of the measuring object SG such as sugar is put into the container A with the spoon SP (S9), the weight of a part of the measuring object SG is obtained by weight calculation in the control unit 7. The data is subjected to display processing and displayed on the display unit 3 (92.1 g in this example). Even if the power button 4 is pressed at this time, the tare subtraction process is not performed again in the control unit 7, and the weight subtracted by the tare subtraction does not change (S10).

  As shown in FIG. 6 (f), when all the remaining objects SG are placed in the container A (S11), the weight of all objects to be measured is converted into data by the weight calculation in the control unit 7 in the control unit 7, and the data Is displayed and displayed on the display unit 3 (164.4 g in this example) (S12). If the power button 4 is pressed for a long time, the power is turned off (S13).

  As shown in FIG. 6G, when the measurement object is directly placed on the placement unit 1 without being tared in step S5 of FIG. 4 (S14), the weight of the measurement object OR is weighted by the control unit 7. It is converted into data by calculation, the data is subjected to display processing, and displayed on the display unit 3 (82.7 g in this example) (S12).

  Next, the operation of the rice mode will be described with reference to the flowcharts of FIG. 4 and FIG. 5 and a series of flowcharts of the use state of FIG. In the rice mode, we first measure the weight of rice (white rice), then calculate the amount of heat and carbohydrate from the measured value of rice (white rice), and finally the weight of rice (white rice) and the amount of heat / carbohydrate. Is displayed on the display unit 3.

  As shown in FIG. 7A, when the switching button 5 is pressed, the control unit 7 switches between the balance mode and the rice mode (S1). As shown in FIG. 7 (b), when the power button 4 is pressed, the power is turned on in the rice mode (NO in S2, S3, S15), and nothing is placed on the placement unit 1, The display unit 3 displays zero.

  First, when only the container B is placed on the placement unit 1, as shown in FIG. 7C, the weight of the container B is converted into data by weight calculation in the control unit 7, and the data is subjected to display processing and display. It is displayed on the lower right of the part 3 (115 g in this example) (S16).

  Then, as shown in FIG. 7D, when the power button 4 is pressed (S17), the control unit 7 performs a taring process, and a weight measurement value obtained by subtracting the weight of the container B is displayed. (In this example, since the weight of the container B is subtracted, it is zero (0)) (S18).

  Here, as shown in FIG. 7 (e), when the container B is removed from the mounting portion (YES in S19), the weight is displayed as negative, and the calorie and the carbohydrate amount are negative in the weight / heat amount and carbohydrate amount conversion calculation. However, the display is processed in the control unit 7 and the display of the amount of heat and the amount of carbohydrate is inadequate without performing the negative display (zero “0” in this example). (S20).

  Examples of the display indicating that the calculation result is inappropriate include zero (0), “unsuitable” characters, a plurality of side-by-side hyphens (−−), and the like.

  From the above state, as shown in FIG. 7 (f), after the rice RC is put into the container B (S21), when the container B is placed on the placing portion 1 (S22), the weight of the rice (white rice) RC is increased. In the control part 7, it converts into data by weight calculation, and weight / heat amount and carbohydrate amount conversion calculation is performed based on the data.

  Further, the weight data and the calculation result data are displayed, and the weight of rice (white rice) RC (lower right of FIG. 7 (f): 160 g) and the amount of heat (upper of FIG. 7 (f): 269 kcl), The amount of carbohydrates (lower left in FIG. 7 (f): 59 g) is displayed on the display unit 3 (S23). Then, when the power button etc. is pressed long, the power is turned off (S13).

  4 and FIG. 5 and a series of flowcharts of the use state of FIG. 8 will explain that rice (white rice) RC is put into the container B without removing the container B from the placing portion. This operation flow is from step (NO in S19), and steps (S1) to (S3), (S15) to (S18), and FIGS. 7 (a) to (d) are the same as those already described. Therefore, explanation is omitted.

  That is, as shown in FIG. 8 (e), when a portion of the rice (white rice) RC to be measured is put into the container B (S24) by rice scoop SH or the like, the weight of the portion of the rice (white rice) RC to be measured is The controller 7 converts the data into data by weight calculation, and the data is subjected to weight / heat amount and carbohydrate amount conversion calculation.

  Further, the weight data and the calculation result data are displayed, and the weight (lower right of FIG. 8 (e): 140 g), calorie (upper part of FIG. 8 (e): 235 kcl), carbohydrate amount (FIG. 7 ( The lower left of f): 51 g) is displayed on the display unit 3, and even if the power button 4 is pressed at this time, the tare subtraction process is not performed again in the control unit 7, and the weight subtracted by the tare subtraction does not change. (S25).

  As shown in FIG. 8 (f), when all of the rice (white rice) RC to be weighed is put into the container B (S26), the same procedure as when a part of the rice (white rice) RC is added is processed. The weight (160 g), the amount of heat (269 kcl), and the amount of carbohydrate (59 g) of the rice (white rice) RC to be weighed are displayed on the display unit 3 (S23).

  It should be noted that the shape, arrangement and installation of each member in the above embodiment need to be selected and determined as appropriate according to the specifications and the like during implementation.

  The present invention is useful as a weight measuring device that measures and displays the weight of various objects, calculates the amounts of various specific components belonging to the object based on the weight of the object, and displays them.
