Description

  The present invention mainly relates to a setting input method for a cooking device and other devices.

  The setting input means in the conventional cooking device includes, for example, a variable resistor for setting cooking time, an operation time determining means for determining an operation time of a timer according to an input value of the variable resistor, and a variable resistor A plurality of light emitting diodes for display disposed around the control unit, and a control unit that performs heating control and driving of the light emitting diodes according to the operation time of the timer determined by the operation time determination unit, Some display the operation time determined according to the output value with a plurality of light emitting diodes for display (see, for example, Patent Document 1).

As shown in FIG. 4, a plurality of light emitting diodes 53 are arranged around a rotary variable resistor 51, and when the variable resistor 51 is operated, the light emitting diodes 53 are sequentially turned on from the left side. By reacting 51 operations with light, a user-friendly feeling of operation is provided.
JP-A-8-200703

  However, in the conventional configuration, when the variable resistor 51 is operated, the display of the light-emitting diode 53 is not stable due to external noise, sliding noise of the variable resistor 51, or the like, or the operation time determining means takes measures against noise. When delay input is performed by means such as coincidence reading a plurality of times, there is a problem that the follow-up of the light-emitting diode 53 may be delayed because the set value for the operation of the variable resistor is delayed.

  The present invention solves the above-mentioned conventional problem, can shorten the time required to determine the set output value, and can hardly cause a determination delay due to noise countermeasures such as erroneous determination due to noise and multiple coincidence reading, It is an object of the present invention to provide a setting input method with improved operational feeling and a cooking device using the same.

  In order to solve the conventional problem, in the setting input method by the stepless input means of the present invention and the cooking device using the same, the stepless input means for performing the operation input for continuously changing the input value; A change rate measuring unit for measuring a change rate of an input value of the stepless input unit; and a step value determining unit for determining a stepped set output value from continuous input, wherein the step value determining unit includes the change rate. The set output value is determined and determined according to the change speed of the input value of the stepless input means measured by the measuring means.

  As a result, it is possible to shorten the time required to determine the stepped output value, and to prevent a determination delay due to noise countermeasures such as erroneous determination due to noise and reading multiple times.

  The setting input method by the stepless input means and the heating cooker using the same according to the present invention can obtain a light operation feeling at the time of setting input, and are easy for the user to understand the setting input method and cooking with the same. Can be obtained.

  The first invention includes a stepless input means for performing an operation input for continuously changing the input value, a change speed measuring means for measuring a change speed of the input value of the stepless input means, and a step from the continuous input. Step value determining means for determining a set output value, wherein the step value determining means determines the set output value according to the change speed of the input value of the stepless input means measured by the change speed measuring means. By using the stepless setting input method with the stepless input means, the time required to determine the stepped output value can be shortened, and noise such as misjudgment due to noise or multiple readings can be achieved. It is possible to make it difficult for a determination delay due to countermeasures to occur.

  In particular, the second invention is the time when the change rate of the input value of the stepless input means measured by the change speed measurement means is less than the first predetermined speed in the first invention. By setting the stepwise set output value according to the input value, the stepped output value at a point earlier than the input data from the stepless input means becomes stable and substantially constant. Can be determined, and the operational feeling of the stepless input means can be improved.

  In the third invention, in particular, in the first invention or the second invention, the change speed of the input value of the stepless input means measured by the change speed measurement means is the second predetermined value. By setting the stepwise set output value not to change while it is below the speed, the slow change speed immediately before the stepped output value becomes stable and almost constant after the step output value is once fixed. Do not continue to determine the output value unnecessarily, such as when the input value changes or the input value changes gradually due to the temperature characteristics of the element and exceeds the threshold value with the adjacent stage. It is possible to reduce the frequency of uncomfortable feeling when operating the stepless input means.

  According to a fourth aspect of the invention, in particular, in the third aspect of the invention, the change rate of the input value of the stepless input unit measured by the change rate measurement unit of the step value determination unit finally exceeds the second predetermined speed. After the value has changed from the input value at the time when it has been changed and the amount of change exceeds a predetermined value, the stepped set output value is not changed regardless of the change speed of the input value of the stepless input means. When the regulation is canceled, if the input value of the stepless input means continues to change at a slow speed after the stepped output value is once determined, the stepless input means It is possible to determine that the operation is continuously performed and change the stepwise output value, and it is possible to reduce the frequency of occurrence of uncomfortable feeling when operating the stepless input means even under special conditions. .

  In a fifth aspect of the invention, in particular, in the first aspect of the invention, the change speed measuring means is the time during which the input value of the stepless input means remains in one set value area of each stepwise set value. The step value determination means is such that the input value of the stepless input means measured by the change speed measurement means is retained in one set value area of each step set value. By setting the stepwise set value when the time exceeds the predetermined time as the set output value, it is possible to simply determine the change rate of the input value of the stepless input means, The operation feeling of the stepless input means can be improved at low cost.

  In a sixth aspect of the invention, in particular, in the fifth aspect of the invention, the input value of the stepless input means measured by the change rate measuring means is one set value of the stepwise set values. By setting the stepped set value at the time when the time stopped in each region exceeds the time set by each region as the set output value, the step set value region width Even when the value differs depending on each set value, the change rate of the input value of the stepless input means can be determined with relatively high accuracy by appropriately setting the threshold value of the stop time, thereby reducing the uncomfortable feeling of operation. Can do.

  According to a seventh aspect of the invention, in particular, in the first to sixth aspects of the present invention, it is assumed that the display means for displaying the set output value determined by the step value determining means and the notifying means for notifying the user of the change in the set output value Thus, the stepless input means can be operated while watching the change of the display means, the operation can be performed while feeling the reaction of the operation while listening to the sound of the notification means, and there is no discomfort due to unnecessary notification, and a feeling of definite operation is obtained. Therefore, it is possible to obtain a setting input method that is easy for the user to understand.

  In particular, in the first to seventh inventions, the eighth invention is applied to the operation input unit of the heating cooker, so that it can be utilized for setting of thermal power, temperature setting, cooking time setting, cooking reservation time setting, etc. It is possible to obtain a cooking device that is easy to use and safe and easy to use for the user because of the operability without any discomfort.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 is a block diagram of a cooking device using a stepwise setting input method using a stepless input means according to an embodiment of the present invention.

  As shown in FIG. 1, the cooking device using the stepwise setting input method by the stepless input means in the present embodiment is a slide volume (stepless input means for changing the setting of the thermal power by the user. ) 1, change speed measuring means 2 for measuring the change speed of the volume position of the slide volume 1, stage value determining means 3 for determining a change in the thermal power setting according to the volume position of the slide volume 1, and the thermal power are displayed. A heating power lamp (display means) 4, a heating means 5 for heating an object to be heated 8 such as a pot containing food, and a heating power lamp 4 controlled according to the heating power determined by the stage value determining means 3. The control means 6 which displays a heating power display and controls the heating means 5 to heat the article 8 to be heated with an appropriate heating power, and the notification means 7 which notifies each time when the heating power setting changes are provided.

  The operation and action of the cooking device using the stepwise setting input method by the stepless input means configured as described above will be described with reference to FIG.

  FIG. 2 shows an operation sequence of the heating cooker using the stepwise setting input method by the stepless input means in the first embodiment of the present invention. First, the volume position of the slide volume 1 is changed by the slide volume 1 in order to change the heating power in a state where the heated object 8 such as a pan in which the food is put is placed in a predetermined position in the area where the volume position of the slide volume 1 is the heating power “0”. To operate. The change speed measuring means 2 measures the change speed of the volume position and transmits it to the step value determining means 3. The step value determining means 3 has a change speed of a predetermined value in the positive direction (first predetermined speed) Vv1 or more or in the negative direction. The heating power set value is not changed and confirmed during the predetermined value (first predetermined speed) Vv2 or more. Accordingly, since the change speed exceeds the predetermined value Vv1 in the positive direction during the period from time t0 to time t1 in FIG. 2, the control means 6 maintains the thermal power “0” before the time t0 when the slide volume 1 is operated, and the thermal lamp 4 Is completely extinguished, which means the thermal power “0”, and the control state of the heating means 5 remains the thermal power “0”.

  That is, when the speed is higher than the first predetermined speed, it is determined that there is noise or a sudden operation, and the change is not confirmed.

  Next, since the change speed of the volume position of the slide volume 1 becomes less than the predetermined value Vv1 in the positive direction at time t1, the step value determination means 3 is a heating power setting area corresponding to the volume position P1 at time t1. The change is confirmed to a certain thermal power “5” and delivered to the control means 6. The control means 6 lights up five lamps from the left, meaning the thermal power “5”, and controls the heating means 5 with the thermal power of the thermal power “5”. Announce changes.

  Thereafter, at time t2, the change speed of the volume position becomes less than a predetermined value (second predetermined speed) Vv3 that is smaller (slower) than the predetermined value Vv1. Here, the step value determining means 3 has a volume position change speed of a predetermined value (second predetermined speed) Vv3 in the positive direction or a predetermined value in the negative direction (change speed is smaller (slower) than the predetermined value Vv2). During the second predetermined speed) Vv4 or less, the change determination of the thermal power setting is prohibited. As a result, even if the volume position changes from the thermal power “5” region to the thermal power “6” region at time t 3, the step value determination means 3 does not confirm the change to the thermal power “6”. Continue the previous fire power "5".

  In other words, when the speed is slower than the second predetermined speed, it is determined that the change is due to the temperature characteristics of the slide volume 1 or just before completion of adjustment at the time of operation, and the change is not confirmed.

  Therefore, the change is confirmed only when the change speed is slower than the first predetermined speed and faster than the second predetermined speed. The first predetermined speed corresponds to an abrupt operation exceeding the speed suitable for the user to perform the adjustment operation, and the second predetermined speed slower than the first predetermined speed is adjusted by the user. It is a change that seems unnatural to think that it is controlling because it is slower than the speed suitable for operation.

  Even after time t3, the change speed of the volume position continues to be less than or equal to the speed Vv3, but the deviation of the volume position from the area of the thermal power “5” spreads. At this time, the stage value determining means 3 is finally changed and confirmed. When moving from the volume position P1 by a predetermined distance dP1 or more, even if the change speed of the volume position remains below the predetermined value Vv3, the stage value determining means 3 releases the restriction prohibiting the determination of the change of the heating power setting. Then, at time t4, it reaches the volume position P2 moved from the volume position P1 by a predetermined distance dP1, so that the stage value determining means 3 is released from the restriction prohibiting the confirmation of change of the thermal power setting. The heating power “6” of the area is changed and confirmed, and the control means 6 turns on the display of the heating power lamp 6 for the six lamps from the left meaning the heating power “6”, and the heating means 5 is changed to the heating power of the heating power “6”. The notification means 7 notifies the change of the thermal power.

  Note that the predetermined distance dP1 is the distance from the volume position at which the last change was confirmed, but the distance from the point in time when the change speed finally falls below the predetermined value Vv3 in the positive direction or the predetermined value Vv4 in the negative direction is similar. An effect is obtained.

  After time t5, the operation of the slide volume 1 is slowly changed in the opposite direction. The change speed of the volume position is faster than the predetermined value Vv4 in the negative direction and slower than the predetermined value Vv2. In this case, the stage value determining means 3 changes and confirms the immediate heating power setting when the volume position exceeds the threshold value of each area of the heating power. Therefore, the stage value determination means 3 changes from the thermal power “6” to the thermal power “5” at time t6, from the thermal power “5” to the thermal power “4” at time t7, and from the thermal power “4” to the thermal power “3” at time t8. It has been confirmed.

  Necessary when selecting a stepped set value using a stepless input means that outputs a continuous value such as a volume by adopting a stepwise setting input method using such a stepless input means. It is possible to obtain an input unit having a relatively good followability while having a noise removal function. In particular, in the case where a stepped display unit is provided and the stepped display unit is interlocked by operation of a stepless input means, quick followability directly leads to a refreshing operation feeling. However, in general, when noise removal is performed, for example, when reading is performed a plurality of times at the frequency of the commercial power supply, a delay time is generated from the reading to the determination of data, leading to deterioration of the operational feeling. Therefore, in this embodiment, as an input method in which the delay time until data confirmation is difficult to occur, the speed of change of the output value of the stepless input means is used, and generally quick response while removing noise with a steep change speed. An input method that realizes Even if there is a gradual change after the change setting has been finalized due to the temperature characteristics of the element such as volume or the like just before the operation of the stepless input means, the change is ignored if it is a slight change. When there are many, it assumes that it is operating intentionally and does not ignore the change. This makes it possible to obtain an input method that can respond as faithfully as possible to the user's operation intention and is easy to operate.

  Furthermore, from the viewpoint of universal design, when a notification is made with a notification means such as a buzzer when the set value changes due to the operation of the stepless input means, the change of the set value is confirmed at a very high speed for the change of the stepless input means. If it is made to follow, the notification sound may be connected, or the notification length necessary for recognition may not be ensured. Therefore, it is necessary not to continue the change of the set value in a short time. However, if the change confirmation is simply delayed in time, the sense of delay is transmitted to the user when the user wants to confirm the change, and the crispness of the operation deteriorates. Even in such a case, the change confirmation does not continue in a short time in this embodiment, but when it is actually desired to confirm, the change can be confirmed at a relatively high speed. It is possible to obtain an input method with less deterioration of the crispness of operation.

(Embodiment 2)
In the second embodiment, since the basic configuration is the same as that of the first embodiment, the operation and action will be described with reference to FIG. 1 for the configuration and further with reference to FIG. .

  (A) of FIG. 3 has shown the operation | movement sequence 1 of the heating cooker using the stepwise setting input method by the stepless input means in the 2nd Embodiment of this invention. First, the volume position of the slide volume 1 is changed by the slide volume 1 in order to change the heating power in a state where the heated object 8 such as a pan in which the food is put is placed in a predetermined position in the area where the volume position of the slide volume 1 is the heating power “0”. To operate. The change speed measuring means 2 measures the time during which the volume position stays in one heating power setting area in order to measure the change speed of the volume position in a simple manner, and transmits it to the step value determining means 3, and the step value determining means 3, when the stopping time exceeds a predetermined time width dt 1, the thermal power set value is changed and confirmed by the thermal power setting corresponding to the volume position. Accordingly, during the period from the time t10 to the time t14 in FIG. 3A, the stage value determining means 3 has the thermal power because the stationary time of each setting area has moved to the next thermal power setting area before reaching the time width dt1. Without confirming the setting change, the control means 6 maintains the heating power “0” before the time t0 when the slide volume 1 is operated, the display of the heating power lamp 4 is kept completely extinguished, which means the heating power “0”, and heating is performed. The control state of the means 5 remains unchanged at the heating power “0”.

  Next, since the time at which the volume position of the slide volume 1 is stopped in the set area of the thermal power 4 after the time t14 exceeds the predetermined time width dt1 when the time reaches the time t15, the stage value determining means 3 is configured so that the volume position is time. The change is confirmed to the thermal power “4”, which is the thermal power setting area corresponding to the volume position P11 at the time t15, and is delivered to the control means 6. The control means 6 turns on the display of the thermal lamp 4 from the left, which means the thermal power “4”, controls the heating means 5 with the thermal power of the thermal power “4”, and the notification means 7 controls the thermal power. Announce changes.

  After that, the volume position continues to remain in the setting area of the thermal power 4, but since there is no change in the thermal power setting, the step value determination means 3 does not dare to confirm the change of the thermal power setting, the display of the thermal power lamp 4 and the heating means 5 The heating power and the notification means 7 are not notified.

  FIG. 3B shows an operation sequence 2 of the heating cooker using the stepwise setting input method by the stepless input means in the second embodiment of the present invention, and FIG. Represents a case where the volume position of the slide volume 1 is changed at another change speed. First, the volume position of the slide volume 1 is changed by the slide volume 1 in order to change the heating power in a state where the heated object 8 such as a pan in which the food is put is placed in a predetermined position in the area where the volume position of the slide volume 1 is the heating power “0”. To operate. The operating speed is slower than that in FIG. The period from the time t20 to the time t21 in FIG. 3B is the setting of the heating power 0, and the time is moved to the setting area of the next heating power 1 at the time t21 before the stop time of the setting area reaches the time width dt1. Therefore, the step value confirmation means 3 does not confirm the change of the thermal power setting, the control means 6 maintains the thermal power “0” before the time t0 when the slide volume 1 is operated, and the display of the thermal power lamp 4 indicates the thermal power “0”. It means that all the meanings are kept off, and the control state of the heating means 5 remains the heating power “0”.

  Next, since the predetermined time width dt1 is reached at t22 before the volume position reaches the thermal power 2 that is the next thermal power setting from time t21, the thermal power setting of the thermal power 1 is once determined as it is. From time t23 to time t25, the stopping time of each region does not reach the predetermined time width dt1, so the setting of the heating power is not fixed, and the heating power 4 is determined at time t26 while maintaining the heating power 1.

  However, although the change speed of the volume position is substantially constant, the thermal power setting is once determined with the thermal power 1 before reaching the target thermal power 4, so that the user feels uncomfortable in operation. This is because the setting area width of the thermal power 1 is larger than the thermal power setting area from the thermal power 2 to the thermal power 7 at the volume position. Originally, the purpose is to simply measure the change speed of the volume position, but if the set area width is not uniform, a difference will occur in the determination threshold speed of the step value of each area. Therefore, the threshold value of the area stop time width in the determination of the thermal power setting is changed according to the thermal power setting area width at the volume position. In the case of the present embodiment, since the region width of the thermal power 1 is wider than the region width from the thermal power 2 to the thermal power 7, the region stationary time width in the determination of the thermal power setting is set to a time width dt2 larger than the time width dt1. To do.

  Since the volume position moves to the region of thermal power 3 at time t23 before the stop time of thermal power 1 reaches the predetermined time width dt2 of thermal power 1, the step value determination means 3 performs the change determination of the thermal power setting at thermal power 1. First, the control means 6 maintains the heating power “0” before the time t0 when the slide volume 1 is operated, the display of the heating power lamp 4 remains completely extinguished, which means the heating power “0”, and the control state of the heating means 5 is It remains unchanged at firepower “0”.

  After that, since the time when the volume position of the slide volume 1 is stopped in the setting area of the thermal power 4 after the time t25 exceeds the predetermined time width dt1 when the time reaches the time t26, the stage value determining means 3 sets the volume position to the time. The change is confirmed to the thermal power “4”, which is the thermal power setting area corresponding to the volume position P12 at the time t26, and is transferred to the control means 6. The control means 6 turns on the display of the thermal lamp 4 from the left, which means the thermal power “4”, controls the heating means 5 with the thermal power of the thermal power “4”, and the notification means 7 controls the thermal power. Announce changes.

  By the way, if the predetermined time width dt2 of the thermal power 1 is the time width proportional to the set area width of the thermal power at the volume position in the sense of measuring the change speed of the volume position which is the original purpose, the determination of the change confirmation is the change speed. Can be determined. In addition, by making a change intentionally without making the area stop time width in the determination of thermal power setting proportional to the area width of each step value setting, create a step value that is easy to confirm the change and a step value that is difficult to confirm the change. And can be set freely as required in the design of the device.

  In the present embodiment, the stepless input means has been described by taking a slide volume as an example. However, for example, a rotary type other than the slide volume or a substantially stepless operation with fine steps. It is also possible to use an electronic volume, an encoder, etc.

  Further, in the present embodiment, the target to be operated by the stepless input means has been described by taking the heating power of the heating cooker as an example, but it may be used for various time settings such as control temperature adjustment of the cooking device and a timer. It is good also as using the stepless input means which changes continuously for the step-wise setting input part in various apparatuses other than a heating cooker.

  As described above, in the present embodiment, the step value determining means determines the set output value according to the change speed of the input value of the stepless input means measured by the change speed measuring means. By adopting the step-wise setting input method with stepless input means, the time required to determine the stepped output value can be shortened, and the determination by noise countermeasures such as erroneous determination due to noise and multiple readings Delay can be made difficult to occur.

  Further, the step value determining means determines the stepped set output value according to the input value when the change speed of the input value of the stepless input means measured by the change speed measuring means falls below a predetermined speed. As a result, the stepped output value can be determined at an earlier time than the input data from the stepless input means becomes stable and substantially constant, and the operational feeling of the stepless input means can be improved. Can do.

  In addition, the step value determination means prevents the stepped set output value from changing while the change speed of the input value of the stepless input means measured by the change speed measurement means is below a predetermined speed. Immediately after the stepped output value is fixed, the input value changes at a slow change rate immediately before it becomes a stable and substantially constant input value, or the input value changes slowly due to the temperature characteristics of the element, etc. Thus, when the threshold value with the adjacent stage is exceeded, it is possible to prevent the output value from being determined unnecessarily, and it is possible to reduce the frequency of occurrence of a sense of incongruity when operating the stepless input means.

  Further, the step value determining means changes the value from the input value at the time when the change speed of the input value of the stepless input means measured by the change speed measuring means last exceeds the predetermined speed, and the change amount is the predetermined amount. After the value is exceeded, the step-wise output value is once fixed by releasing the restriction that the step-wise set output value does not change regardless of the change speed of the input value of the stepless input means. If the input value of the stepless input means continues to change at a slow speed later, it is determined that the operation of the stepless input means is continuously performed, and the stepwise output value is changed. In addition, it is possible to reduce the frequency of occurrence of uncomfortable feeling when operating the stepless input means even under special conditions.

  Further, the change rate measuring means measures the time during which the input value of the stepless input means remains in one set value area of each step set value, and the step value determining means measures the change speed. The stepwise set value when the time when the input value of the stepless input means measured by the means stays in the set value area of each step set value exceeds the predetermined time is set and output. By determining the value, it is possible to simply determine the change speed of the input value of the stepless input unit, and to improve the operational feeling of the stepless input unit at low cost.

  In addition, the step value determination means sets the time during which the input value of the stepless input means measured by the change speed measurement means stays in one set value area of each step set value for each area. By setting the stepwise set value when the specified time is exceeded as the set output value, the threshold for the stop time is set appropriately even when the area width of the stepped set value differs for each set value. By setting to, the change speed of the input value of the stepless input means can be determined with relatively high accuracy, and the uncomfortable feeling of operation can be reduced.

  In addition, since the display means for displaying the set output value determined by the step value determination means and the notification means for notifying the user of the change of the set output value, the stepless input means can be provided while watching the change of the display means. It is possible to operate, listen to the sound of the notification means, operate while feeling the response of the operation, there is no discomfort due to unnecessary notification, can obtain a definite feeling of operation, and obtain a setting input method that is easy for the user to understand Can do.

  In addition, by applying it to the operation input section of the heating cooker, it can be used for thermal power setting, temperature setting, cooking time setting, cooking reservation time setting, etc. A safe and easy-to-use cooking device can be obtained.

  As described above, the stepwise setting input method using the stepless input means according to the present invention and the heating cooker using the same can obtain a light operation feeling at the time of setting input. It can be applied to the use of an interface unit that performs stepwise setting input of equipment.
