Description

  The present invention relates to an input display device and a heating cooker, and more particularly to an input display device including a touch panel and a heating cooker including the input display device.

  Conventionally, in this type of input display device, when a finger or an input pen is brought into contact with the touch panel, if the contact point is within the region of the button image, it is determined that an input corresponding to the button image has been made. On the other hand, if the contact point is outside the button image area, it is determined that no input corresponding to the button image has been made.

  By the way, when the button image is small, there is a problem that if the touched part is removed from the button image due to shaking of the finger, the input by the button image cannot be continued and an input error occurs.

Japanese Patent Laid-Open No. 5-74000

  Accordingly, an object of the present invention is to provide an input display device that is easy to input and can prevent input errors.

In order to solve the above problems, an input display device according to the present invention displays an at least one icon image on a display screen and has an input display unit having a touch panel,
A position determination unit that determines whether or not the contact point of the user's finger or pen-like object to the touch panel is a detection region corresponding to the icon image;
An input determination unit that determines that an input corresponding to the icon image has been made when the position determination unit determines that the contact location is a detection region corresponding to the icon image;
When the position determination unit determines that the contact location is a detection region corresponding to the icon image, detection corresponding to the icon image is performed during a period in which a user's finger or pen-like object is in contact with the touch panel. And a detection area expansion control unit that expands the area.

  According to the input display device of the present invention, when the position determination unit determines that the contact location is a detection region corresponding to the icon image, the user's finger or pen-like object contacts the touch panel. During this period, the detection area enlargement control unit widens the detection area corresponding to the icon image.

  Therefore, according to the present invention, even when a small icon image is in contact with the display screen of the touch panel, even if the contact portion protrudes from the icon image due to finger shake or the like, the contact portion is within the detection area that is expanded. If there is, it can be determined that the input corresponding to the icon image has been made. Therefore, according to the present invention, it is possible to prevent the input from being canceled due to the trembling of the finger, etc., and it is easy to continue the input even if the finger is slightly shaken, and an input display device that is easy to input can be realized.

In the input display device according to the embodiment, the detection area expansion control unit is
After the detection area is expanded, when the position determination unit determines that the contact point is a detection area corresponding to an icon image different from the icon image corresponding to the expanded detection area, the expanded detection is performed. Return to the detection area before expanding the area.

  According to this embodiment, by returning the expanded detection area to the previous detection area, the input of the previously touched icon image is cancelled, and the detection area of another icon image is expanded and another icon image is used. Easy to continue input.

In the input display device according to an embodiment, the input display unit displays a plurality of icon images on the display screen,
A detection sensitivity setting unit configured to set the detection sensitivities of the detection regions of the plurality of icon images to values of two or more steps different from each other according to each icon image;

  According to this embodiment, detection sensitivity corresponding to each icon image can be set. For example, by increasing the detection sensitivity of the icon image such as the heating stop key of the heating cooker compared to the detection sensitivity of other keys, even if the heating stop key is pressed weakly, key input can be made effective. When urgent key input is required, key input can be performed quickly, and an emergency stop of heating can be handled. In addition, for example, by making the detection sensitivity of an icon image such as a heating start key of a heating cooker lower than the detection sensitivity of other keys, the input can be validated only when the key is strongly pressed. Therefore, it is possible to avoid heating from being started by an inadvertent operation.

  In the input display device according to the embodiment, the predetermined icon image is set wider than another icon image different from the icon image, and the detection area of the predetermined icon image is set as the another icon image. The icon enlargement setting unit is set to be wider than the detection area.

  According to this embodiment, it becomes easy to input with a predetermined icon image. For example, when the icon image is used as a heating stop key of a heating cooker, it is difficult to perform key input when urgent key input is required. Can be avoided, and can respond to an emergency stop of heating.

  Further, the input display device according to the embodiment includes a detection area narrowing setting unit that sets a detection area of the icon image narrower than the icon image for a predetermined icon image.

  According to this embodiment, the detection area narrowing setting unit narrows a predetermined icon image detection area smaller than the icon image, so when inputting, another adjacent icon image is input. Can be avoided.

In the input display device according to an embodiment, the input determination unit is
For the predetermined icon image, when the position determination unit determines that the contact location represents the position of the detection region corresponding to the predetermined icon image for a predetermined time or more, While it is determined that the predetermined icon image has been input, there is a period during which the position determination unit determines that the contact location represents the position of the detection area corresponding to the predetermined icon image. When it is determined that the time is less than the predetermined time, it is determined that the predetermined icon image is not input.

  According to the input display device of this embodiment, the input determination unit does not input the icon image until the user's finger or pen-like object is brought into contact with the detection region of the icon image for a predetermined time or more. Judge that Therefore, for example, in an icon image such as a heating start key of a heating cooker, it is possible to avoid heating from being started by an inadvertent operation.

  The cooking device of the present invention includes the input display device.

  According to this cooking device, input by an icon image becomes easy and an input error can be avoided.

  According to the input display device of the present invention, even in the case where a small icon image is in contact with the display screen of the touch panel, even if the contact portion protrudes from the icon image due to finger shake or the like, it is within the detection region where the contact portion is widened. If there is, it can be determined that the input corresponding to the icon image has been made. Therefore, according to the present invention, it is possible to avoid an input being canceled due to finger shake or the like, and it is possible to realize an input display device that can easily input a key even when the key is small and can avoid a key input error.

  The button group 7 is displayed on an input display section 75 that is formed by extending the color liquid crystal panel 61 and the touch panel 62. A region surrounded by a one-dot chain line of the input display portion 75 indicates an input region R1.

  FIG. 5 shows a control block diagram of the cooking device. This cooking device includes a control device 300 including a microcomputer and an input / output circuit in the electrical component section 17 (shown in FIG. 2). The control device 300 includes a superheated steam generation heater 20, a circulation fan motor 19, a cooling fan motor 16, an air supply damper motor 44, an exhaust damper motor 60, an operation panel 5, an internal temperature sensor 29, a thawing sensor 50, A feed water pump 70, a steam generator 12, and a magnetron 80 are connected. Based on the signal from the operation panel 5 and the detection signals from the internal temperature sensor 29 and the thawing sensor 50, the control device 300 performs the superheated steam generation heater 20, the circulation fan motor 19, the cooling fan motor 16, and the air supply damper. The motor 44, the exhaust damper motor 60, the operation panel 5, the feed water pump 70, the steam generator 12 and the magnetron 80 are controlled.

  The control device 300 includes a position information acquisition unit 300a, a position determination unit 300b, a contact determination unit 300c, an input determination unit 300d, a detection region expansion control unit 300e, and a key region expansion setting unit 301 as an icon expansion setting unit. . Further, the control device 300 includes a detection area narrowing setting unit 300f-2.

  As shown in FIGS. 3 and 7, the detection area narrowing setting unit 300f-2 is narrower than the key images for the start key 74, the cancel key 72, the manual heating key 73, and the return key 71 as the initial setting. Detection areas 74a, 72a, 73a, 71a are set.

  In addition, the position information acquisition unit 300a acquires position information of a contact location of the user's finger or pen-like object to the input region R1 in the input display unit 75 of the touch panel 62. In addition, the position determination unit 300b displays a key image of the manual heating key 73, the cancel key 72, the return key 71, and the warm start key 74 in which the position information of the contact point is displayed on the input display unit 75 (see FIG. 3). It is determined whether or not the position of the detection area corresponding to (shown by a solid line) is represented. In addition, the contact determination unit 300c determines whether or not a user's finger or a pen-like object is in contact with the input area R1 of the touch panel 62.

  In addition, the input determination unit 300d of the control device 300 determines that the position determination unit 300b represents the position information of the contact location in the detection area corresponding to the key image of the input display unit 75. In this case, it is determined that a key input corresponding to the key image has been made.

  Further, the input determination unit 300d determines that the position determination unit 300b determines that the position information of the contact location does not represent a position in the detection area of the key image of the input display unit 75. While the determination unit 300c continues to determine that the user's finger or pen-like object is in contact with the input region R1 of the touch panel 62, the position information acquisition unit 300a continues to acquire the position information of the contact location. Then, the input determination unit 300d displays the key image when the position determination unit 300b determines that the position information of the contact location represents the position in the detection area corresponding to the key image of the input display unit 75 during the period. It is determined that the corresponding key input has been made. The input determining unit 300d does not perform a key input corresponding to the key image when the contact determining unit 300c determines that the user's finger or pen-like object is no longer in contact with the input area of the touch panel 62. Judge.

  In addition, the detection area expansion control unit 300e is configured so that the position determination unit 300b has a key image of any one of the manual heating key 73, the cancel key 72, the return key 71, and the warm start key 74. The contact determination unit 300c continues to determine that the user's finger or pen-like object is in contact with the input region R1 of the touch panel 62. During this period, the detection areas corresponding to the key image are expanded from the default detection areas 73a, 72a, 71a, 74a to the detection areas 73b, 72b, 71b, 74b.

  The detection area enlargement control unit 300e corresponds to a key image different from the key image corresponding to the detection area where the user's finger or pen-like object touches after expanding the detection area. When the position determination unit 300b determines that it is a detection area, the detection area expanded from the key image is returned to the detection area before expansion.

  The control device 300 and the operation panel 5 constitute the input display device of this embodiment.

  When cooking with superheated steam in the cooking device having the above configuration, the superheated steam generating heater 20 shown in FIG. 2 is turned on and the circulation fan 18 is driven to rotate. Thus, the saturated steam supplied from the steam generator 12 to the upstream side in the vicinity of the steam suction port 15 of the circulation unit 14 enters the steam suction port 15 into the circulation unit 14 which is in a negative pressure due to the rotation of the circulation fan 18. And is blown out from the steam supply port 22 into the superheated steam generator 21. And it is heated by the superheated steam production | generation heater 20 of the superheated steam production | generation apparatus 21, and becomes superheated steam. A part of this superheated steam blows downward into the heating chamber 13 from a plurality of first steam outlets 24 provided on the top surface of the lower heating chamber 13. Further, another part of the superheated steam is blown out into the heating chamber 13 from the second steam outlet 25 of the heating chamber 13 through the steam duct 100.

  Then, the superheated steam supplied into the heating chamber 13 heats the heated object 27 mounted on the net 40 on the tray 30, and then faces the steam inlet 15 of the circulation unit 14 on the right wall surface of the heating chamber 13. Then, the air is sucked into the circulation unit 14 from the suction port 28 formed in this manner. Then, the circulation of returning to the heating chamber 13 through the circulation path again is repeated.

  On the other hand, when performing the operation | movement which heats or heats the to-be-heated material 27 with non-superheated steam, while turning off the superheated steam production | generation heater 20, the circulation fan 18 is stopped. Then, since the circulation fan 18 is stopped, the circulation air flow is not generated in the circulation path, and the saturated steam supplied from the steam generator 12 to the upstream side in the vicinity of the steam suction port 15 of the circulation unit 14 is It is not forcibly sucked into the circulation unit 14. Thereby, the to-be-heated material 27 is steamed or warmed by the saturated water vapor that naturally flows into the heating chamber 13 by the vapor pressure.

  Here, on the left wall surface and the right wall surface in the heating chamber 13, as shown in FIG. 2, locking portions 39 a, 39 b, and 39 c that lock both ends of the tray 30 are provided in three stages in the vertical direction. Yes. The steam supply pipe 34 is arranged so as to be located slightly above the upper locking portion 39a. In the “steaming warming mode”, when the two trays 30 loaded with the object 27 to be heated are arranged in the upper stage and the middle stage, all the nozzles of the steam supply pipes 34 installed in the steam introduction chamber 36 (see FIG. The left side opening of the circular portion of No. 34 is inclined downward in the direction of the heating chamber 13. By doing so, the saturated water vapor drawn from the obliquely downward nozzle of the steam supply pipe 34 is applied to the heated object 27 regardless of the position of the tray 30 on which the heated object 27 is mounted. Can do. Therefore, it is possible to prevent steaming spots and warming spots from being generated in the upper-middle two-stage heated object 27 without operating the blowing direction from the nozzle of the steam supply pipe 34.

  Next, an operation when the button group 7 displayed on the input display unit 75 of the operation panel 5 is operated will be described. First, the contact determination unit 300c determines whether a user's finger or a pen-like object is in contact with the input area R1 of the touch panel 62. When the contact determination unit 300c determines that the user's finger or pen-like object is in contact with the input region R1, the position determination unit 300b displays the position information of the contact location on the input display unit 75. It is determined whether or not it represents a position in one of the detection areas 73a, 72a, 71a, 74a among the key images of the manual heating key 73, the cancel key 72, the return key 71, and the start key 74. .

  For example, when the position determination unit 300b determines that the position information of the contact point indicates the position in the detection region 74a of the start key (heating start key) 74, the input determination unit 300d starts the warming. It is determined that the key input of the key (heating start key) 74 has been made. Then, a desired cooking menu selected by the user touching the touch panel 62 of the color liquid crystal display unit 6 in advance and selecting an image displayed on the color liquid crystal panel 61 is executed under the control of the control device 300. For example, when the position determination unit 300b determines that the position information of the contact location represents a position in the detection area 73a of the manual heating key 73, the input determination unit 300d It is determined that key input has been made. Then, a screen for manually setting the high frequency output and the heating output is displayed on the color liquid crystal display unit 6 by the control device 300, and the user touches the touch panel 62 to make a desired setting. Further, for example, when the position determination unit 300b determines that the position information of the contact location represents the position in the detection area 72a of the cancel key (heating stop key) 72, the input determination unit 300d It is determined that the key 72 has been entered. Then, even during cooking, heating by the heating cooker is stopped under the control of the control device 300. Further, for example, when the position determination unit 300b determines that the position information of the contact location represents the position within the detection area 71a of the return key 71, the input determination unit 300d receives the key input of the return key 71. Judge that it was made. Then, the control device 300 returns the screen display of the color liquid crystal panel 61 to the previous screen display.

  When the position determination unit 300b determines that the position information of the contact location does not represent the position in the detection region for any of the keys 71 to 74 of the button group 7 of the input display unit 75, During the period in which the contact determination unit 300c continues to determine that the user's finger or pen-like object is in contact with the input area R1 of the touch panel 62, the input determination unit 300d causes the position information acquisition unit 300a to Continue to acquire information. During this period, when the position determination unit 300b determines that the position information of the contact location represents a position in any detection region of the keys 71 to 74 of the button group 7 of the input display unit 75. The input determining unit 300d determines that a key input corresponding to the key image has been made.

  For example, at first, the touched portion by the user's finger or pen-like object is warmed up, so that the touch panel can be used outside the detection area of any key image of the start key 74, manual heating key 73, cancel key 72, and return key 71. If the user's finger or pen-like object is kept in contact with the input area R1 62 and the contact point is moved into the detection area of the start key 74, the key input by the start key 74 can be performed. Therefore, the user can input the start key 74 by touching the input area R1 of the touch panel 62 while sliding the user's finger or pen-like object into the detection area 74a of the start key 74. This makes it easier to enter keys. The same applies to the other keys of the button group 7 (manual heating key 73, cancel key 72, and return key 71).

  On the other hand, when the position determination unit 300b determines that the position information of the contact location does not represent the position in the detection area of any of the key images of the input display unit 75, the contact determination unit 300c determines that the touch panel 62 When it is determined that the user's finger or pen-like object is no longer in contact with the input area R1, the input determination unit 300d determines that no key input corresponding to any of the key images is performed.

  Further, the detection area enlargement control unit 300e, for example, touches the detection area 74a of the start key 74 with the user's finger or pen-like object, and the start key 74 is input by the input determination unit 300d. When the determination is made, the detection area 74a of the start key 74 is expanded while the user's finger or pen-like object is in contact with the touch panel 62. As a result, even if the user's finger or pen-like object is shaken during key input and the touched portion of the touch panel 62 is touched, the user's finger or pen-like object is expanded even when the start key 74 is removed from the original detection area 74a. As long as the detection area 74b is touched, it is possible to avoid that the key input of the start key 74 is continued and the key input is cancelled.

  In addition, the detection area enlargement control unit 300e expands the detection area 74a, and the contact area corresponds to the expanded detection area 74b. Therefore, the detection area enlargement control unit 300e displays a key image (for example, the cancel key 72) different from the start key 74. When the position determination unit 300b determines that the detection area is a corresponding detection area, the detection area 74b that has been expanded is returned to the detection area 74a that has been expanded. The same applies to the other keys of the button group 7 (manual heating key 73, cancel key 72, and return key 71).

  8 and 9 are flowcharts for explaining an operation of controlling the input display unit 75 of the operation panel 5 by the control device 300 in this embodiment.

  First, the control device 300 displays the button group 7 shown in FIGS. 3 and 7 on the color liquid crystal panel 61 in step S101. Next, in step S102, the detection area narrowing setting unit 300f-2 performs initial setting of the start key 74, the cancel key 72, the manual heating key 73, and the return key 71 as initial settings as shown in FIG. Detection areas 74a, 72a, 73a, 71a that are narrower than the key image are set.

  In step S103, the contact determination unit 300c determines whether or not the user's finger or pen-like object is in contact with the input area R1 of the touch panel 62. If it is determined in step S103 that the user's finger or pen-like object is in contact with the input area R1 of the touch panel 62, the process proceeds to step S104, and it is determined in step S103 that the user's finger or pen-like object is not in contact. Then, step S103 is repeated.

  In step S104, the position determination unit 300b detects the detection area of each key image of the manual heating key 73, the cancel key 72, the return key 71, and the warm start key 74 in which the position information of the contact point is displayed on the input display unit 75. It is determined whether or not any one of 73a, 72a, 71a, and 74a is represented. If it is determined in step S104 that the position information of the contact location represents the position of any one of the detection regions of each key image, the process proceeds to step S105, and the position of the contact location is determined in step S104. If it is determined that the information does not represent the position of any of the detection areas of each key image, the process proceeds to step S106.

  In step S105, the detection area enlargement control unit 300e enlarges the detection area corresponding to the key image corresponding to the position information of the contact location, and proceeds to step S108. FIG. 7 shows an example of enlarged detection areas 73b, 72b, 71b and 74b corresponding to the key images of the manual heating key 73, the cancel key 72, the return key 71 and the start key 74.

  On the other hand, in step S106, the input determining unit 300d determines whether or not the contact determining unit 300c determines that the user's finger or pen-like object is in contact with the input area R1 of the touch panel 62. If it is determined in step S106 that the contact is made, the process returns to step S104. If it is determined that the contact is not made, the process proceeds to step S107. In step S107, the input determining unit 300d determines that no key input has been made and returns to step S103.

  In step S108, the input determining unit 300d determines that a key input corresponding to the key image corresponding to the position information of the contact location has been made, and proceeds to step S109. In step S109, the input determining unit 300d determines whether or not the contact determining unit 300c determines that the user's finger or pen-like object is in contact with the input area R1 of the touch panel 62. If it is determined in step S109 that the contact is made, the process proceeds to step S121 in FIG. 9. If it is determined in step S109 that the contact is not performed, the process proceeds to step S110, and the detection area enlargement control unit 300e performs the key operation. After returning the detection area corresponding to the image to the initial setting, the process returns to step S103.

  On the other hand, in step S121 of FIG. 9, the detection area enlargement control unit 300e determines whether or not the contact point of the user's finger or pen-like object to the input area R1 is in the enlarged detection area, If it is determined that the contact location is in the enlarged detection area, the process proceeds to step S122, the enlarged detection area is maintained, and the process returns to step S108. On the other hand, if it is determined in step S121 that the contact point is not in the enlarged detection area, the process proceeds to step S123. In step S123, after the detection area enlargement control unit 300e expands the detection area, the contact location is a detection area corresponding to a key image different from the key image corresponding to the expanded detection area. If the position determination unit 300b determines, the process proceeds to step S124. On the other hand, if it is determined in step S123 that the contact location is not a detection area corresponding to another key image, the process proceeds to step S110. In step S124, the detection area enlargement control unit 300e returns the detection area corresponding to the original key image to the initial setting, and returns to step S105 using the other key image as the newly selected key image.

  As described above, according to the input display device of this embodiment, when the user's finger or pen-like object is brought into contact with the detection area of the key image, the detection area expansion control unit 300e expands the detection area. Therefore, after the contact, if the contact location of the user's finger or pen-like object is within the expanded detection area even if it is out of the original detection area, the input determining unit 300d determines the key corresponding to the key image. It is determined that input has been made. Therefore, even when the user's finger shakes during key input, the key input can be prevented from being canceled as long as the contact point is within the expanded detection area even if it is out of the original detection area. Is maintained.

  According to this embodiment, for example, as shown in FIG. 10A, the user's finger or pen-like object contact point 500 to the input area R1 of the touch panel 62 is a key of the button group 7 indicated in the input area R1. As shown in FIG. 10B, the user's finger or pen-like object remains in contact with the input area R1 of the touch panel 62 even outside the area of the initial detection area 501a of the key image 501 corresponding to If the contact location 500 is moved into the detection area 501a of the key image 501, key input corresponding to the key image 501 can be performed.

  Further, according to this embodiment, as shown in FIG. 10B, when the contact location 500 is moved to the detection area 501a of the key image 501, the detection area enlargement control unit 300e causes the detection area 501a of the key image 501 to be detected. As shown in FIG. 10C, the detection area 501b can be enlarged. Accordingly, as shown in FIG. 10D, when the finger is shaken during the key input, the key input is maintained as long as the contact location 500 is out of the initial detection area 501a but is in the expanded detection area 501b. It is possible to avoid canceling the key input.

  Also, according to this embodiment, as shown in FIG. 10E, when the contact location 500 of the user's finger or pen-like object is out of the expanded detection area 501b, as shown in FIG. The expanded detection area 501b is returned to the original initial detection area 501a, and the input determination unit 300d determines that the key input corresponding to the key image 501 has not been made. Therefore, contact with a user's finger or pen-like object at a position far away from the key image 501 can be invalidated.

  In this embodiment, the detection area enlargement control unit 300e expands the detection area, and then the position determination unit 300b corresponds to the detection area where the contact point by the user's finger or pen-like object is expanded. When it is determined that the detection area corresponds to a key image different from the image, the expanded detection area is returned to the detection area before expansion. Thus, by narrowing the detection area of the original key image that is no longer selected and expanding the detection area of another newly selected key image, it is possible to easily perform input using the key image.

  In addition, according to this embodiment, the detection area narrowing setting unit 300f-2 initially detects the detection area 73a of each key image of the manual heating key 73, the cancel key 72, the return key 71, and the start key 74 as an initial setting. Since 72a, 71a, and 74a are narrower than the key image, it is possible to avoid erroneously performing key input of another adjacent key image when performing key input. It should be noted that the detection area narrowing setting unit 300f-2 performs initial setting only for a predetermined key among the manual heating key 73, the cancel key 72, the return key 71, and the start key 74 rather than the key image. The detection area may be narrowly initialized. For example, the manual heating key 73, the cancel key 72, and the return key 71 are set to narrow detection areas 73a, 72a, and 71a, while the start key 74 is initialized to the same detection area as the key image area. Good.

  Thus, according to the detection area narrowing setting unit 300f-2, for example, the manual heating key 73, the cancel key 72, and the return key 71 that are arranged close to each other have an effective area 73a, narrower than each key image. 72a and 71a can be set. As illustrated in FIG. 12 corresponding to an example of this setting, the effective areas 701a, 702a, 703a of the arranged key images 701, 702, 703 are set to be narrower than the key images 701, 702, 703. Therefore, it is possible to avoid erroneously performing key input for another adjacent key image when performing key input.

  Further, the input display device of this embodiment has a key area enlargement setting unit 301, which is a key of a cancel key (heating stop key) 72 as an example of a predetermined key image. The image region and the initial detection region are set wider than the key image region of the manual heating key 73 and the return key 71 adjacent to the cancel key 72 and the initial detection region. Thereby, for example, it is possible to avoid a situation in which it is difficult to input the cancel key (heating stop key) 72 when an emergency heating stop is required. Also, the key area enlargement setting unit 301 sets the image area of the start key 74 and the initial detection area wider than the image of the manual heating key 73, the cancel key 72, the return key 71, and the initial detection area. To do. Thereby, since the frequency of input is the highest, key input of the start key 74 can be facilitated.

  In addition, the input display device of the above embodiment may include a detection region enlargement setting unit 300f-1 indicated by a broken line in FIG. 5 instead of the detection region narrowing setting unit 300f-2. The detection area enlargement setting unit 300f-1 uses a predetermined key image (for example, the cancel key 72) among the key images of the manual heating key 73, the cancel key 72, the return key 71, and the warm start key 74. As shown by a two-dot chain line in FIG. 7, a detection area wider than the key image (for example, detection area 72c) is set as an initial setting. In addition to the cancel key 72, one or more of the manual heating key 73, the return key 71, and the warm start key 74 are detected by the detection area enlargement setting unit 300f-1 wider than the key image. The areas 73c, 71c, and 74c may be initialized. The detection area enlargement setting unit 300f-1 initially sets a detection area narrower than the key image for key images other than the predetermined key image, as in the detection area narrowing setting unit 300f-2. The key image and its detection area may be initialized to the same area. According to the detection area enlargement setting unit 300f-1, the detection area 601a of the predetermined key image 601 is initially set wider than the key image 601 as illustrated in FIG. According to the detection area enlargement setting unit 300f-1, since the detection area 601a of the key image 601 can be widely initialized even if the key image 601 is small, it is easy to input even a small key image. For the predetermined key image among the key images of the manual heating key 73, cancel key 72, return key 71 and warm start key 74, a detection area of the same area as the key image is set as an initial setting. A detection area match setting unit 300f-0 may be provided. The detection area match setting unit 300f-0 may initialize a detection area wider than the key image for a key image other than the predetermined key image. A narrow initial setting may be used. Furthermore, a single detection region setting unit having both the detection region matching setting unit 300f-0, the detection region expansion setting unit 300f-1, and the detection region narrowing setting unit 300f-2 may be provided.

  Moreover, in the said embodiment, you may provide the key high sensitivity setting part 300g-1 shown in FIG. 5 as a detection sensitivity setting part. This key high sensitivity setting unit 300g-1 is configured to select a predetermined key image (for example, the cancel key) from the key images of the manual heating key 73, the cancel key 72, the return key 71, and the warm start key 74 shown in FIG. 72) is set higher than the key sensitivity of another key image different from the predetermined key image. The key high sensitivity setting unit 300g-1 makes it easy to input a predetermined key (for example, cancel key 72). For example, when an emergency heating stop is required, the key of the cancel key (heating stop key) 72 is used. Input can be made promptly. Moreover, in the said embodiment, you may provide the key low sensitivity setting part 300g-2 shown in FIG. 5 as a detection sensitivity setting part. This key low sensitivity setting 300g-2 is used for a predetermined key image (for example, the start key 74 for heating) of the key images of the manual heating key 73, the cancel key 72, the return key 71, and the start key 74. The key sensitivity is set lower than the key sensitivity of another key image different from the predetermined key image. According to the key low sensitivity setting unit 300g-2, key input can be made effective only when the key sensitivity of a predetermined key is lowered and the key is strongly pressed. It is possible to prevent heating from being started by an inadvertent operation at the start key (heating start key) 74 or the like due to the warming of the vessel. Note that one key sensitivity setting unit having both functions of the key high sensitivity setting unit 300g-1 and the key low sensitivity setting unit 300g-2 may be provided as a detection sensitivity setting unit.

  In the above embodiment, the input determination unit 300d of the control device 300 is configured such that the manual heating key 73, the cancel key 72, the return key 71, and the start key 74 are predetermined keys (for example, the start key 74 (heating start key)), the position determination unit 300b determines the position information of the contact point for the predetermined time (for example, 1 second or 2 seconds) or more. When it is determined that the position in the detection area corresponding to the key image of the key is represented, it is determined that the key input of the predetermined key has been performed, while the position determination unit 300b determines the position information of the contact location. Is determined to represent a position in the detection area corresponding to the key image of the predetermined key is less than the predetermined time. When you may be one that determines a key input of the predetermined key is not made. In this case, the input determination unit 300d determines that the key input of the key image is made only when the user's finger or pen-like object is brought into contact with the detection area of the key image for a predetermined time or more. Therefore, for example, the start key (heating start key) 74 can be prevented from being heated by an inadvertent operation because the heating cooker is warm.

  Further, in the above embodiment, the key image 501 in the state in which the key input illustrated in FIGS. 10B and 10C is made by the control device 300 is compared with the key image 501 in which the key input illustrated in FIG. 10A is not performed. By changing the color (hue, lightness, saturation), changing the contrast, changing the pattern such as shading, etc., it can be easily distinguished from other key images without key input. May be.

  In the said embodiment, although the input display apparatus with which the cooking-by-heating machine was equipped was demonstrated, an input display apparatus is not restricted to this, You may apply the input display apparatus of this invention to another electronic device. For example, the input display device of the present invention can be applied to a mobile phone or a mobile terminal.

Applicable to input display devices.

  In addition, examples of the cooking device according to the present invention include not only an oven range that uses superheated steam, but also an oven that uses superheated steam, an oven range that does not use superheated steam, and an oven that does not use superheated steam.

  In the cooking device of the present invention, healthy cooking can be performed by using superheated steam or saturated steam in a microwave oven or the like. For example, in the cooking device of the present invention, superheated steam or saturated steam having a temperature of 100 ° C. or higher is supplied to the food surface, and the superheated steam or saturated steam adhered to the food surface is condensed to give a large amount of condensation latent heat to the food. So it can efficiently transfer heat to food. Moreover, when condensed water adheres to the food surface and salt and oil are dropped together with condensed water, salt and oil in the food can be reduced. Further, the inside of the heating chamber is filled with superheated steam or saturated steam to be in a low oxygen state, thereby enabling cooking while suppressing food oxidation. Here, the low oxygen state refers to a state in which the volume percentage of oxygen is 10% or less (for example, 2 to 3%) in the heating chamber.
