In the present embodiment, two AA batteries are used for the power supply unit 19, but there is no problem even if different power sources such as a solar panel is provided on the grip unit 1.

  FIG. 3 is a block diagram of the measuring spoon in the first embodiment, FIG. 4 is a schematic diagram showing the information content stored in the information storage unit of the measuring spoon in the first embodiment, and FIG. 5 is the present embodiment. It is a schematic diagram which shows the display content of the display part of the measuring spoon in the form 1. The operation of the measuring spoon according to the first embodiment will be described in detail below with reference to FIGS.

  When the power switch 15 is pressed by the user, the power supply unit 19 is connected to the measurement control unit 11. The weighing controller 11 can latch (hold) the power ON state by turning on the semiconductor switch 20 earlier than the power switch 15 is opened. With this configuration, when not in use, the power supply unit 19 is completely cut off from the circuit and does not wear out. Further, power is supplied to the measurement unit 10 via the measurement control unit 11.

  Thereafter, the measurement control unit 11 performs an initialization process. In the initialization process, the measurement control unit 11 supplies power from the grip unit power transmission unit 7 to the tray unit power reception unit 8 in a non-contact manner, and supplies power to the tray unit transmission / reception unit 6 and the information storage unit 5. Furthermore, the measurement control unit 11 transmits an information transmission request from the grip unit transmission / reception unit 9 to the saucer unit transmission / reception unit 6 in a non-contact manner. The saucer transmission / reception unit 6 reads the information in the information storage unit 5 shown in FIG. 4, and corresponding menu name, calorie amount per unit weight, weight g (gram) per unit output voltage of strain gauge, initial display unit and No. Is transmitted to the grip part transmission / reception part 9, and the measurement control part 11 stores the information received by the grip part transmission / reception part 9. Further, the weighing control unit 11 regards the current loading amount of the tray unit 2 as zero, performs zero point adjustment, and displays zero on the display unit 12. As shown in FIG. 5, the menu name 21 and the display unit 22 indicate the information No. of the information read from the information storage unit 5 as described above. 1 is displayed by default. Of course, the measurement control unit 11 may be equipped with a non-volatile memory and the menu No. used last time may be set as the default, but in this embodiment, an inexpensive configuration is adopted. 1 is adopted as the default display. It is possible to further improve the usability by setting the number of the frequently used menu to a young number when storing in the information storage unit 5. The display unit 12 displays a number 23 indicating the weight or calorie of the food, an operation state (“Σ” indicating the integration mode, “HOLD” indicating the display fixing mode) 24, and a symbol 25 indicating the remaining battery level. .

FIG. 6 is a circuit diagram showing the configuration of the measuring unit of the measuring spoon in the first embodiment. The measurement part of the measuring spoon in this Embodiment 1 is demonstrated using FIG.
As shown in FIG. 2, four strain gauges 26 are installed on the surface of the connection receiving portion 4, and a power source 19 (voltage E) is connected between a pair of opposing power source terminals as shown in FIG. A bridge circuit for taking out the detection voltage Vg from the pair of output terminals is formed. In FIG. 6, the strain gauge 26 is represented by a resistance R. Next, in a state where the connection portion 3 is inserted into the connection receiving portion 4, when food is scooped up into the tray portion 2, stress is applied to the connection receiving portion 4 and the strain gauge 26, thereby deforming. The measurement control unit 11 can measure the weight of the food picked up on the tray 2 by detecting the displacement amount of the strain gauge 26 as the detection voltage Vg.

  The measuring unit 10 in the present embodiment is composed of an inexpensive strain gauge 26, but may be composed of other elements that detect displacement or load, such as a load cell and a piezoelectric sensor. In addition, the four strain gauges 26 are set in pairs, and two sets of strain gauges are attached to the front and back surfaces, respectively, and a bridge circuit is formed to increase the detection voltage Vg and eliminate the need for temperature correction. It is possible.

  FIG. 7 is a characteristic diagram showing the relationship between the measuring part of the measuring spoon and the weight in the first embodiment. In FIG. 7, the relationship between the detection voltage Vg and the weight is linear. This inclination is the weight g (gram) per unit output voltage of the strain gauge stored in the information storage unit 5. The above-described zero point adjustment will be described in detail below.

When the initialization point C1 shown in FIG. 7 is initialized or the zero point adjustment button is pressed for a long time, the measurement control unit 11 stores the current detection voltage A1. The weight B1 is recognized as zero. After that, when food is loaded on the saucer unit 2 and the measurement point C2 is reached, the weighing control unit 11 detects the detection voltage A2-A1, that is, the measured weight is
B2-B1 Formula (1)
Is displayed on the display unit 12. When the display unit is calories, based on the information in the information storage unit 5, the value obtained by multiplying the detected weight B2-B1 by the calorie amount per unit weight (B2-B1) × kcal / g Formula (2)
Is displayed on the display unit 12. By calculating in this way, the measuring spoon 40 in the present embodiment can calculate the weight and calories of the food loaded on the saucer unit 2. Of course, it can be displayed as weight.

  Each time the switch 17 for switching the display unit is pressed, the measurement control unit 11 switches between the mathematical formulas (1) and (2) described above to calculate and updates the display on the display unit 12. By doing in this way, it becomes possible to switch a weight (gram, g) and a calorie (cal, kcal) easily by a user's intention, and the user-friendly measuring spoon 40 can be provided.

  When the switch 15 for performing integration and menu switching is pressed and held, the measurement control unit 11 performs menu switching. The menu name 20 on the display unit 12 blinks, and each time the switch 15 is pressed briefly, the menu No. is switched to 1 → 2 → 3 →. The menu number and name displayed at this time are displayed by the measurement control unit 11 using information read from the information storage unit 5 at the time of initialization. When the switch 15 is pressed and held while the menu that suits the user is displayed, the menu is fixed. In this way, the food to be picked is determined by the shape of the saucer part 2, and the information is stored in the information storage part 5 of the saucer part 2, so that the user can follow the intention from the minimum necessary menu group. This makes it possible to easily select a menu and to provide a measuring spoon 40 that is easy to use.

  When the switch 15 for performing integration and menu switching is briefly pressed, the mode shifts to the Σ mode. The Σ mode is used when the cooked rice 2 is moved a plurality of times from the rice cooker to the tea bowl, for example, when the tray portion 2 has a rice paddle shape. When the weight or calorie of the first cooked rice is displayed, the displayed weight or calorie Z1 is stored by briefly pressing the switch 15, and the weighing control unit 11 adds Z1 + the current weight or calorie amount to the display unit 12. Display the value. When the first cooked rice is put in the bowl and the second cooked rice (weight or calorie amount Z2) is loaded on the saucer unit 2, the weighing control unit 11 displays the added value of Z1 + Z2 on the display unit 12. By doing so, the user does not need to memorize the weight or calorie amount of the first time, and even if it is put into the bowl from the rice cooker multiple times, the weight or calorie quantity of the rice in the bowl is easily used. It is possible to provide a measuring spoon 40 that is simple and easy to use.

FIG. 8 is a perspective view showing a saucer part of the measuring spoon in the first embodiment. The saucer part of the measuring spoon in this Embodiment 1 is demonstrated using FIG.
FIG. 8 shows the tray portion 2 having various shapes. 8 (a) is rice scoop corresponding to the cooked rice menu, FIG. 8 (b) is noodle eggplant corresponding to the noodle menu, FIG. 8 (c) is onion egg corresponding to the soup menu such as miso soup, and FIG. 8 (d) is seasoning. Spoon shape corresponding to the food. The food to be picked up by each of the plurality of saucers 2 is determined, and by connecting the saucer 2 having a shape suitable for the food to be measured to the connection receptacle 4, the user can select a menu according to the intention from a limited menu. It becomes possible to select easily, and it becomes possible to provide the measuring spoon 40 that is easy to use.

9 and 10 are schematic diagrams showing the contents stored in the information storage unit of the saucer unit of the measuring spoon in the first embodiment. The contents stored in the information storage section of the saucer section of the measuring spoon according to the first embodiment will be described with reference to FIGS. 9 and 10.
As shown in FIG. 10 (b), when the saucer part 2 has a spoon shape, the initial display unit is g because the frequency of measurement with grams (g) such as seasonings is high. Thus, by storing in advance in the information storage unit 5 an initial display unit suitable for food that can be picked up by the shape of the saucer unit 2, the number of button operations by the user can be reduced, improving usability. It is possible. In addition, the operation | movement sequence of the measurement control part 11 mentioned above in FIG. 11 is shown.

  FIG. 12 is a schematic diagram showing the relationship between the heat resistance of the components of the measuring spoon and the abnormal temperature threshold in the first embodiment, and FIG. 13 is a circuit diagram showing the configuration of the measuring unit of the measuring spoon in the first embodiment. FIG. 14 is a characteristic diagram showing the relationship between the detection voltage of the measuring unit of the measuring spoon and the temperature in the first embodiment, and FIG. 15 shows a main part control sequence of the measuring control unit of the measuring spoon in the first embodiment. It is a flowchart. The temperature detection means of the measuring spoon in this Embodiment 1 is demonstrated using FIG. 12 thru | or FIG.

  The temperature detected by the temperature detection means 13 is transmitted to the measurement control unit 11. The measurement control unit 11 includes the detected temperature from the temperature detection unit 13 and the measurement unit 10, the information storage unit 5, the measurement control unit 11, the display unit 12, the power supply unit 19, the grip unit 1, and the saucer unit 2 shown in FIG. 12. An abnormal temperature threshold set below the heat-resistant temperature is compared, and if any abnormal temperature threshold is exceeded, temperature abnormal information is output to the first notification unit 41. The 1st alerting | reporting part 41 inputs the temperature abnormality information from the measurement control part 11, and alert | reports abnormality, such as an audio | voice or a warning sound, to the exterior which is a user. Thus, the measuring spoon 40 which can prevent the malfunction by the more than heat-resistant temperature of a component by comparing with the abnormal temperature threshold value set below the heat-resistant temperature of each component which is a component of the measuring spoon 40 is provided. It becomes possible to do. In the present embodiment, the thermistor is used as the temperature detection means 13, but as shown in FIG. 13, one strain gauge in the bridge circuit of the strain gauge 26 of the measurement unit 10 is fixed by the measurement control unit 11. The temperature may be calculated by switching to Rs27. Details of the calculation method will be described below.

  When calculating the temperature, the weighing control unit 11 turns off the switch Sa28 and turns on the switch Sb29. Thereby, the measurement unit 10 becomes a bridge circuit including the three strain gauges 26 and the fixed resistor Rs27, and the detection voltage changes from Vg to Vgt. Since the detection voltage Vgt is obtained as a function of the resistance change amount Δr of the strain gauge 26 due to a temperature change, Δr, that is, the temperature can be calculated by measuring Vg and Vgt.

  FIG. 14 shows the relationship between the detection voltage Vgt and temperature. At the factory initialization point D1 shown in FIG. 14 (that is, equivalent to the resistance value R of the strain gauge 26 at the strain gauge reference temperature T = 0 ° C.), the measurement control unit 11 stores the current detection voltage F1. When the food is loaded on the saucer unit 2 during use and reaches the measurement point D2 (that is, when the resistance value of the strain gauge 26 increases by Δr at the temperature T = T1), the measurement control unit 11 The detection voltage F2 is stored, and F2-F1, that is, the measured temperature can be calculated as F2-F1.

  As described above, even when the strain gauge 26 is distorted, the ambient temperature of the strain gauge 26 can be obtained.

  In the present embodiment, the switch Sa28 and the switch Sb29 are exclusively turned on and off, but the switch Sa28 is turned on and the switch Sb29 is turned off when measuring the weight, and both the switches Sa28 and Sb29 are turned on when measuring the temperature. Even in this case, the temperature can be calculated. In this case, since the switch Sa28 is always ON, it is possible to reduce the cost by reducing the switch Sa28. Further, the switch Sa28 and the switch Sb29 may be replaced by a microcomputer built in the measurement control unit 11, and the cost can be reduced.

  Further, in the present embodiment, when the power switch 15 is turned on, the weighing control unit 11 switches the switch Sa28 and the switch Sb29 at predetermined time intervals and automatically calculates the temperature as shown in FIG. There is no need for the user to operate, and it is possible to provide a measuring spoon 40 that is safe and free from malfunctions.

(Embodiment 2)
FIG. 16 is a main part schematic diagram showing the main part of the measuring spoon according to Embodiment 2 of the present invention. As shown in FIG. 16, the measuring spoon in the present embodiment has the strain gauge 26 according to the first embodiment disposed inside the resin of the saucer portion 2, and a waterproof connector 30 is provided in the saucer portion 2 and the connection receptacle portion 4. . Two strain gauges 26 are arranged on each of the upper and lower surfaces of the space. That is, since the measurement control unit 11 reads information in the information storage unit 5 through the waterproof connector 30 and supplies power, the saucer transmission / reception unit 6, the grip unit power transmission unit 7, the saucer unit power reception described in the first embodiment. The part 8 and the grip part transmission / reception part 9 are not necessary. As shown in the first embodiment, there is no problem even if it is a non-contact connection.

  By arranging the strain gauge 26 inside the resin of the tray part 2 in this way, it is possible to measure with the dish part 2 having the largest strain amount, and a small amount of food can be accurately measured.

In addition, since the food to be measured, that is, the weight, is determined by the shape of the saucer portion 2, it is possible to select a strain gauge suitable for each saucer portion 2. Specifically, since the saucer portion 2 has a scooping shape (FIG. 9A), the cooked rice to be measured is required to have strength against stirring, so a high strain resistance gauge is used. Since only a small amount of food is measured in the spoon shape (FIG. 10 (b)), it is possible to improve the measurement accuracy using a low strain resistance gauge, and to provide a measuring spoon 40 with high reliability and high accuracy. Is possible. Also, there is a material for the saucer portion 2 suitable for each foodstuff. For example, the rice scoop shown in FIG. 9 (a) is preferably a resin so as not to damage the kettle of the jar rice cooker, and the ball shown in FIG. 10 (a). Insulators are preferably heat-resistant metals in order to measure foods with high temperatures. Since the coefficient of thermal expansion differs depending on the material of the saucer part 2, it is possible to individually select a strain gauge 26 suitable for the material for each saucer part 2, and reduce errors due to the temperature-dependent characteristics of the strain gauge 26. In addition, it is possible to suppress failures such as excessive stress applied to the strain gauge 26.
