Embodiments according to the present invention will be described below with reference to the drawings.
(Best Embodiment)
A cooking scale according to the best mode of the present invention will be described. As shown in FIG. 1, this cooking scale 1 has a weighing pan 11 on its upper surface side, and objects to be weighed placed on the weighing pan 11, such as potatoes and chicken, are shown in FIG. The second measuring unit 12 measures the weight. The weighing unit 12 uses a well-known load cell. In the weighing unit 12, as an example, four strain gauges are bonded to different positions of a support bar that supports the weighing pan 11, and these four strain gauges are connected to each other. The Wheatstone bridge circuit is configured.

  The control unit 20 controls the entire operation of the cooking scale 1 and can measure the weight of the weighing object on the weighing pan 11 by changing the voltage in the Wheatstone bridge circuit of the weighing unit 12. ing. As shown in FIG. 2, the control unit 20 includes an amplifier 21, an A / D converter 22, a microprocessor 23, a ROM 24, a RAM 25, an EEPROM 26, and the like.

  The amplifier 21 amplifies the voltage signal representing the measurement value generated by the measuring unit 12, and the A / D converter 22 can process the amplified analog voltage signal in the microprocessor 23. Thus, it is converted into a digital signal.

  When the power supply is turned on and the main cooking scale 1 is activated, the microprocessor 23 reads a predetermined program relating to display of the recipe of the dish (display of the weight of the cooking material), measurement of the weighing object, etc. from the ROM 24. The data is read out from the RAM 25 and executed. The EEPROM 26 stores material data representing the weight of each material of the dish for each dish.

  The material data for one dish is used for displaying a recipe, and includes the name of the dish, the name of the material used for the dish, and the basic weight of each material. The basic weight of each material is, for example, the amount of each material corresponding to one person of the dish. As an example of cooking, for the pickled pepper, the name of the dish is “Karashizuku”, and the name of the ingredients and its basic weight are “cucumber 1000 g”, “hot pepper 50 g”, “sugar 135 g”, “salt 50 g”, “ Mirin 30g ". These are registered and stored as material data.

  The display unit 30 is a liquid crystal display, and displays a measurement value of the measurement object, a target weight of the cooking material, an operation guidance to the user, and the like. As shown in FIG. 1, the operation unit 40 is provided with a power key 41, ten keys 42a to 42j, an enter key 43, a return key 44, cursor movement keys 45a to 45d, a tare key 46, and a mode selection key 47. It has been.

  The power key 41 is a key for the user to turn on / off the power of the cooking scale 1. The numeric keys 42a to 42j are keys for the user to input numerical values, and the determination key 43 is a key for the user to determine (determine) the input. The return key 44 is a key for displaying the previous screen on the display unit 30 when a series of input operations are performed. The cursor movement keys 45a to 45d are keys for moving the cursor displayed in the display unit 30 up, down, left and right, and the tare key 46 sets a zero point for weighing by taring. It is a key for instructing.

  In particular, in the cooking scale 1, the user can input katakana. This katakana input is performed using a combination of the numeric keys 42a to j and the determination key 43 or the like, or a combination of the cursor movement keys 45a to 45d and the determination key 43 with the display of a predetermined software keyboard on the display unit 30. It is done by using.

  The mode selection key 47 selectively instructs one of the operation modes of (1) recipe registration mode, (2) recipe display mode, (3) recipe sequential weighing mode, and (4) scale mode. It is a key for. That is, when the user presses the mode selection key 47, the mode selection screen shown in FIG. On this mode selection screen, the user moves the cursor C up and down by pressing the cursor movement keys 45a and 45b, and presses the enter key 43 while the cursor C is displayed on the left side of the desired operation mode. Thus, the operation mode is selected (selection is input). The main feature of the cooking scale 1 is the operation in the recipe display mode and the recipe sequential weighing mode.

  (1) The recipe registration mode is an operation mode for the user to register the basic weight of each ingredient of cooking in the cooking scale 1. That is, in the cooking scale 1, in this recipe registration mode, registration of material data for each dish is accepted for various dishes such as dishes frequently cooked by the user, and recipe display is performed based on the registered material data. The mode or recipe sequential weighing mode is executed.

  When the recipe registration mode is selected on the mode selection screen (FIG. 3), first, a guidance display such as “Please enter a dish name” is displayed on the display unit 30 to prompt entry of a dish name. (FIG. 4A). In the case of the above-described pickled pickles, the user inputs “Karashige” from the operation unit 40 using the numeric keys 42a to 42j and the determination key 43 and determines the input. The input with the basic weight of the material is accepted sequentially.

  In the input of the material name and the basic weight, specifically, a guidance display such as “Please input the material name” is first performed on the display unit 30, and one of the ingredients to be cooked is displayed. Is prompted to enter the material name (FIG. 4B). When the user inputs “cucumber” from the operation unit 40 and decides this input, the guidance display “input weight” prompts the user to input the basic weight of the material “cucumber”. It is.

  When the user inputs “1000” in response to the guidance display, the material name and the basic weight are similarly input for other materials. When the input of the material name and the basic weight is determined for one of the other materials, here “Karashi” (FIG. 4C), the other materials are also sequentially displayed on the display unit 30. The user inputs from the operation unit 40 with the display of.

  When the input of the material name and its basic weight is completed for all the materials and a predetermined key operation such as pressing of the return key 44 is performed, registration of material data for one dish is completed. Along with the registration of the material data, the material name and the basic weight of the registered cooking ingredients are displayed in a list form on the display unit 30 (FIG. 4D).

  (2) In the recipe display mode, the cooking scale 1 has a target of other ingredients based on the weighing of one of the ingredients of the dish for one dish registered in the recipe registration mode. This is an operation mode for displaying the weight. In this recipe display mode, the target weight of the material is displayed in a list format (FIG. 5E described later).

  When the recipe display mode is selected on the mode selection screen (FIG. 3), a guidance display such as “Please select a dish name” is displayed on the display unit 30 and a list of dishes registered in the recipe registration mode is displayed. Is displayed. For example, in FIG. 5A, “Nikujaga”, “Karashizuku”, “Oden”, “Cookie”, and “Kimchi” are displayed on the display unit 30 as the names of registered dishes. These displays prompt the user to select one of the registered dishes.

  When the user moves the cursor C to the left side of “Karashizuke” in these dishes using the cursor movement keys 45a and 45b, and the user presses the decision key 43 in this state, the “Karashizuke” The selection is determined.

  When a dish is selected, guidance such as “Please select a main ingredient” is displayed on the display unit 30 and a list of ingredients of the selected dish is displayed. In the example in which “Karashizuke” is selected, as shown in FIG. 5B, specifically, “cucumber”, “kurashi”, “sato”, “shio”, “Mirin” are displayed as the material names. It is displayed on the part 30. With these displays, the user is prompted to select a main ingredient from among a plurality of ingredients of the selected dish.

  When the user moves the cursor C to the left side of “cucumber” among these materials using the cursor movement keys 45a and 45b and presses the enter key 43, the selection of “cucumber” is made. Is determined.

  When the main material is determined as described above, the main material is weighed after taring. First, regarding taring, guidance such as “please place a container” is displayed on the display unit 30, and normal weighing is performed on the container placed on the weighing pan 11 (FIG. 5 ( c)). In the example of pickled pepper, when the cucumber as the main ingredient is weighed, the measured value of the empty container is displayed as “125 g”.

  Here, when the user presses the tare key 46, the zero point is set with the container placed thereon, and then the main material is weighed. In the measurement of the main material, first, a guidance display such as “Place the main material. Cucumber” is performed on the display unit 30 (FIG. 5D). This display prompts the main material to be placed on the weighing pan 11 and to be weighed. When the user places the cucumber on the weighing pan 11, the measured value “826 g” is displayed.

  When the user presses the enter key 43 in this state, the measured value of the main material is determined, and the target weights of all the materials other than the main material are calculated based on the material data. And as shown in FIG.5 (e), the material name and the target weight are displayed on the display part 30 by list form about all the materials. In the center of the screen of the display 30, in addition to the indication of “Cucumber 826 g” for the main material, indications such as “Kalash 41 g”, “Sato 112 g”, “Shio 41 g”, “Millin 25 g” for the secondary material Has been done.

  In the cooking scale 1, it is possible to display the measured value of the material placed on the weighing pan 11 on the right side of the screen while maintaining the display of the material list. This display state is maintained in the cooking scale 1 until a predetermined key operation is performed, and the user can select “material”, “sato”, “shio”, “milin”, and other materials as appropriate. Each material is weighed in sequence while taring each container.

  (3) In the recipe sequential weighing mode, as in the recipe display mode, the target weight of the other ingredients is determined based on the weighing of one of the ingredients of the dish for one of the registered dishes. Is displayed. Here, unlike the recipe display mode, other materials are weighed while the target weights of the materials are sequentially displayed one by one (FIG. 6E described later).

  When the recipe sequential weighing mode is selected on the mode selection screen (FIG. 3), the dish selection (FIG. 6 (a)), main ingredient selection (FIG. 6 (b)), Prior to material weighing, taring (FIG. 6C) and main material weighing (FIG. 6D) are sequentially performed. When the user presses the enter key 43 when the main material is weighed and the measured value is determined, the weighing of the sub-material is guided in sequence while appropriately taring as necessary.

  An example of pickled pepper will be described. When the measurement value of the main material “cucumber” is determined during the display of the screen shown in FIG. 6D of the display unit 30, the sub-material “must” (FIG. 6E) ), “Sato”, “Shio”, and “Mirin” weighing are guided in order. In FIG. 6 (e), a guidance display such as “Please put 41g on the mustard” is displayed for “mustard” which is one of the sub-materials, and a normal weighing operation can be performed. . Here, the measurement value “41 g” is displayed in the lower right corner of the screen of the display unit 30.

  When the user presses the enter key 43 in this state, the weighing of the next sub-material “Shi” is guided, and the user places this “Shi” on the weighing pan 11, ”. These are repeated for all sub-materials to complete the weighing of all materials.

  (4) The weighing mode is an operation mode in which the cooking scale 1 performs normal weighing on the weighing object on the weighing pan 11 and displays the measured value on the display unit 30. When the scale mode is selected on the mode selection screen (FIG. 3), the cooking scale 1 functions as a normal scale.

  As described above, the main feature of the cooking scale 1 is the calculation and display of the target weight of each material in the recipe display mode and the recipe sequential weighing mode. Hereinafter, the control in these operation modes will be described more specifically.

  The program executed by the control unit 20 (microprocessor 23) includes a dish display control unit 20a, an ingredient display control unit 20b, a measured value acquisition unit 20c, a zero point setting unit 20d, and a target weight calculation unit schematically shown in FIG. 20e and the target weight display control unit 20f are included. Regardless of which one of the recipe display mode and the recipe sequential weighing mode is selected, the operations of the units 20a to 20e other than the target weight display control unit 20f are the same.

  Further, as described above, in the recipe registration mode, material data is registered for various dishes, and the material data storage unit 20g stores these material data. The material data storage unit 20g may be a predetermined area in the EEPROM 26.

  Explaining each of the units 21 to 26, the dish display control unit 20a displays a list of registered dishes on the display unit 30 based on the dish name included in the material data in the material data storage unit 20g. (FIG. 5A). With this display being performed, the user can select one of the dishes in the list from the operation unit 40 (using the cursor movement keys 45a and 45b and the enter key 43 in FIG. 1). It is.

  The material display control unit 20b controls to display each material on the display unit 30 based on the material name included in the material data for the dish selected by the user (FIG. 5B). In this display state, the user can select one of the materials being displayed from the operation unit 40 as the main material.

  The measurement value acquisition unit 20 c controls the measurement object on the weighing pan 11 to acquire a measurement value obtained by measurement by the measurement unit 12 and display the measurement value in the lower right corner or the like of the display unit 30. (As described above, the signal representing the measurement value is output from the measurement unit 12 (load cell) to the control unit 30 via the amplifier 21 and the A / D converter 22.)

  Prior to the measurement of the main material and other materials, the container for putting the material is placed on the weighing pan 11 and is measured by the measurement value acquisition unit 20c (FIG. 5 (c)). Can be instructed to perform taring from the operation unit 40 (by pressing the tare key 46 in FIG. 1). The zero point setting unit 20d performs zero point setting in response to the taring instruction. The weighing value is reset to “0g” by taring.

  The user puts the main material selected by himself / herself in the container on the weighing pan 11 in accordance with the display on the material display control unit 20b. In the measurement value acquisition unit 20c, the weight (measurement value) of the main material is acquired, and the target weight calculation unit 20e is based on the acquired weight of the main material and the basic weight of each material in the material data, The target weight of each other material according to the weight of the main material is calculated.

  For example, as shown in FIG. 4 (d), the basic weight of the main material “cucumber” in the material data for “Kalashosuke” is “1000 g”, and the four sub-materials “Karashi”, “Sato”, “Shi” , “Mirin” has a basis weight of “50 g”, “135 g”, “50 g”, and “30 g”, respectively. In this case, if the measured value of “cucumber” is “826 g” (FIG. 5D), the ratio (826/1000) between the measured value of the main material and the basic weight is calculated as the basic weight of each of the auxiliary materials. The target weight is calculated by multiplying by. That is, the target weights of `` Karashi '', `` Sato '', `` Shio '', `` Mirin '' are `` 41 g '' (= 50 g x 0.826), `` 112 g '' (= 135 g x 0.826), `` 41 g '' (= 50 g x 0.826) ), “25 g” (= 30 g × 0.826).

  The target weight display control unit 20f (FIG. 7) performs control so that the target weights of the other materials calculated by the target weight calculation unit 20e are displayed on the display unit 30. If the recipe display mode is selected, the target weight display control unit 20f displays the target weights of the other materials in a list format (FIG. 5 (e)). In the recipe sequential weighing mode, the target weight display control unit 20f switches a plurality of other materials one by one in order by an operation on the operation unit 40 (pressing the enter key 43 in FIG. 1), and the target weight of each material. Is displayed on the display unit 30 (FIG. 6E).

  Next, the control unit 20 controls the process in the recipe display mode by executing the process in each of the above-described units 20a to 20f in the flow shown in the flowchart of FIG. In step 1 (hereinafter, step is abbreviated as S), first, the names of all registered dishes are read from the material data in the material data storage unit 20g. In subsequent S2, a list of these read dishes is displayed on the display unit 30 (FIG. 5A).

  Next, in S3, input by the cursor movement keys 45a and 45b and the enter key 43 for selecting a dish name is accepted, and in S4, it is determined whether or not the enter key 43 has been pressed. When the dish to be displayed as a recipe is determined by pressing the enter key 43 (YES in S4), in S5, all the ingredients used in the dish are selected from the material data for the selected dish. The name is read. In S6, the list of material names is displayed on the display unit 30 and the selection of the main material is prompted (FIG. 5B).

  Subsequently, in S7, as with S3 described above, input by the cursor movement keys 45a and 45b and the decision key 43 for selection of the main material is accepted. If it is determined in S8 that the enter key 43 has been pressed (YES in S8) and the main material is determined, a guidance display for prompting the weighing of the container is performed in S9 (FIG. 5 (c)). .

  Further, in S10, a weighing operation such as acquisition of a measurement value from the measurement unit 12 and display of the measurement value on the display unit 30 is performed. In S11, it is determined whether or not the tare key 46 has been pressed. . When the user places a container on the weighing pan 11 in response to the guidance display at S9 and then presses the tare key 46 (YES at S11), the container is placed on the weighing pan 11 at S12. In this state, 0 point is set for each measured value.

Thereafter, in S13, a guidance display for prompting the measurement of the main material is performed on the display unit 30 (FIG. 5D), and in the subsequent S14, the measurement operation is performed as in S10 described above. If it is determined in S15 that the enter key 43 has been pressed (YES in S15), the basic weight of the material is read from the material data in the material data storage unit 20g in S16, and other than the main material in S17. The target weight of other materials is calculated. That is, as described above, the target weight of each of the other materials is calculated by multiplying the basic weight of each of the other materials by the ratio between the measured value of the main material and the basic weight.

  In S18, the measured value of the main material and the target weight for the other material are displayed in a list (FIG. 5 (e)). In order to allow the user to weigh other materials by looking at this display, in S19 The weighing operation is performed in the same manner as S10 described above, and this weighing operation is continued until the return key 44 is pressed. That is, when the return key 44 is pressed in S20 (YES in S20), this weighing operation ends, and the process exits from the recipe display mode.

  In these recipe display modes, when the user cooks a desired dish out of registered dishes, the user simply selects one of a plurality of ingredients as a main ingredient and places it on the weighing pan 11. The target weight of other ingredients in the dish is automatically calculated and displayed. According to these indications about the target weights of other materials, user convenience is improved.

  For example, when a user wants to use all of the main ingredients for a certain dish, the user can know the target weight of the other ingredients simply by placing the main ingredients on the weighing pan 11, The material can be weighed conveniently. When one of beef lump, 3 onions, 2 pieces of fish, etc. is used as the main material, and other materials are weighed based on this, the user calculates the other materials from the measured value of the main material. It is cumbersome to obtain the target weight. In such a case, the display of the target weights of the other ingredients on the main cooking balance 1 is effective.

  Moreover, the control part 20 controls the process in a recipe sequential display mode by performing the process in each part 20a-f by the flow shown to the flowchart of FIG. 9 next. In the flowchart of FIG. 9, the same step numbers (S1 to S17) are assigned to the same processes as those in FIG.

  In FIG. 9, by the process up to S17, a main material is selected and measured for a desired dish, and target weights of other materials are calculated. In subsequent S21, a guidance display for prompting the metering of one material among the other materials is performed (FIG. 6 (e)). The user places a container or other material on the weighing pan 11 according to the guidance display. In S <b> 22, a weighing operation such as acquisition of a measured value from the measuring unit 12 and display of the measured value on the display unit 30 is performed on the container or other material on the weighing pan 11.

  If it is detected in S23 that the tare key 46 has been pressed (YES in S23), it is assumed that an empty container is placed on the weighing pan 11, and a zero value is set in S24. The process is returned to S22. If it is detected in S25 that the enter key 43 has been pressed (NO in S23 and YES in S25), another material is placed on the weighing pan 11 with or without the container. As a result of the measurement, in S26, it is determined whether or not the measurement has been performed for all the materials other than the main material.

  If all other materials are not weighed in S26 (NO in S26), the target weight display target is set to the next material in S27, and the processing from S21 is performed for this material. Repeated. That is, in S25, the determination key 43 is a means for instructing to sequentially switch a plurality of other materials other than the main material one by one, and in S21 thereafter, the determination key 43 is switched in accordance with the instruction. The target weight of other materials is displayed. On the other hand, if all of the other materials have been weighed (YES in S26), the process in the recipe sequential weighing mode ends.

  Even in these recipe sequential weighing modes, as in the recipe display mode, the user simply selects the main ingredients of the desired dish and places them on the weighing pan 11 to automatically calculate target weights of other ingredients. As a result, the convenience of the user is improved. In particular, in this recipe sequential weighing mode, each of the other materials is displayed one by one and the object to be weighed is clear, so there is an error that the target weight of the other subsidiary material is mismeasured for one subsidiary material. It is hard to occur.

(Other embodiments, etc.)
Although the present invention has been described above with specific embodiments, the present invention is not limited to the above-described embodiments, and can be modified and implemented without departing from the scope of the present invention.
a. For example, in the above embodiment, the main material is selected by the user. Of course, the selected material may be another sub-material that is not the main material. That is, the user is allowed to select any one material among a plurality of materials, and the ratio between the measured value and the basis weight obtained for the selected material is multiplied by the basis weight of the other material, Thereby, the target weight of the other material is calculated.

b. A plurality of dishes are displayed on the display unit 30, and any one of the dishes is selected from the operation unit 40. Unlike this, for example, it is possible to configure a storage medium for each dish so that material data for one dish is stored in one card-shaped storage medium. In this case, the cooking scale is provided with a data reading unit capable of reading material data from the storage medium with one of the card-shaped storage media inserted. The user selects a dish by inserting one of the storage media into the data reading unit.

c. Of course, the taring is not necessarily performed immediately before the measurement of the main material, and the processing in S9 to S15 in FIGS. 8 and 9 may be similar to the processing in S21 to S25. That is, depending on whether the tare key 46 or the enter key 43 is pressed, the object to be weighed on the weighing pan 11 is a container, one of materials (or one of materials placed in the container). ) May be determined.

  That is, in a series of user operations in the recipe display mode or the recipe sequential weighing mode, the user appropriately selects a material to be put in the container and a material not to be put in the container, and tares the material to be put in the container. Operate as follows. According to this, the user can perform a series of operations more conveniently.

d. It is possible to represent the main material by including data indicating which material is the main material in the material data and attaching the marking M to the main material as shown in FIG. 5 (e), for example. is there. According to such marking, even if the amount of material increases, the user can immediately know what has been weighed as the main material and what should be weighed as another material other than the main material.

e. In the recipe registration mode, the material data is registered for each dish. Unlike this, the user can input the material data separately on a PC (personal computer) so that the material data input on the PC side can be transmitted from the PC to the cooking scale. Communication means may be provided on the cooking scale. The user can register material data more easily by using a PC. Of course, it is also possible to transmit / receive material data between PCs.

f. It is also assumed that the entire amount of main ingredients that the user wants to use for cooking cannot be placed on the weighing pan 11 at one time. In preparation for such a case, an operation key such as a measurement continuation key can be provided in the operation unit 40.

  That is, when the user presses the measurement continuation key with a part of the main material placed on the weighing pan 11, the measurement value for the part of the main material is stored. Subsequently, when the user presses the weighing continuation key while another part of the main material is placed, the measurement value for the other part of the main material is stored. These steps are repeated, and finally, when the user presses the enter key or the like, the total of these measured values is calculated as the measured value of the total amount of the main material. This calculated measured value can be used for calculating the target weight of the material other than the main material.
