Description

  The present invention relates to an image input device, a home appliance, and a heating cooker.

  Conventionally, as a cooking device, there is one described in JP-A-2005-265216 (Patent Document 1). Although this heating cooker is provided with the display part which can change a display by operation of a touch panel, what can be displayed on a display part is only the preset number and character. Therefore, the display on the display unit is not tasteful.

  Therefore, if the user can display the picture drawn on the touch panel on the display unit, the display on the display unit can be interesting, and if the picture can be associated with the menu and displayed on the display unit, the menu can be selected. It is preferable because mistakes can be reduced.

  However, a problem arises when characters with a background are drawn on the touch panel.

  More specifically, for example, when drawing a character with the sun in the background, it is assumed that after drawing the character, the sun is drawn. At this time, if the line for drawing the sun overlaps with a part of the character, a part of the character disappears and the line for drawing the sun remains. Therefore, when drawing the sun after drawing the character, the sun is drawn while avoiding the character, so the sun is difficult to draw.

  On the other hand, when drawing letters after drawing the sun, the sun is in the background, so there is no problem even if it disappears by overlapping the lines of letters. Therefore, when drawing a character after drawing the sun, there is no difficulty in drawing as when drawing the sun after drawing a character.

  As described above, if a character and its background are to be easily drawn on the touch panel, the character must first be drawn after the background is drawn. That is, if it is desired to simplify the drawing on the touch panel, there is a problem that the order of drawing is limited and the degree of drawing freedom is reduced.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an image input device that can easily draw an image and that can increase the degree of freedom of drawing an image, as well as a home appliance and a heating cooker provided with the image input device. Is to provide.

In order to solve the above problems, an image input device of the present invention is
A display unit having a touch panel operated by touching a user's finger or a contact object while displaying an image having a first layer and a second layer lower than the first layer;
A control device for controlling the display unit based on an operation signal received from the touch panel,
The control device
Selection determination means for determining whether or not the second layer is selected;
Upper layer changing means for changing the second layer to an upper layer of the first layer when the selection determining unit determines that the second layer is selected;
Contact determination means for determining whether the finger or the contact object is in contact with the touch panel when the second layer is higher than the first layer;
When the contact determination means determines that the finger or the contact object is in contact with the touch panel when the second layer is higher than the first layer, the finger or the contact object Image drawing means for drawing an image along the locus of contact in the second layer;
Separation determining means for determining whether or not the finger or the contact object is separated from the touch panel;
When it is determined by the separation determination means that the second layer is higher than the first layer, and the finger or the contact object is separated from the touch panel, the second layer is changed to the first layer. And a lower layer changing means for changing to a lower layer of one layer.

  According to the above configuration, when the selection determining unit determines that the second layer is selected, the upper layer changing unit changes the second layer to the upper layer of the first layer. When the second layer is higher than the first layer and the contact determination unit determines that the finger or the contact object is in contact with the touch panel, the image drawing unit An image along the locus of contact is drawn on the second layer. Thereby, even if a part of the second layer image overlaps a part of the first layer image, a part of the data of the first layer image remains without being erased. When the second layer is higher than the first layer, if the separation determining unit determines that the finger or the contact object is separated from the touch panel, the lower layer changing unit sets the second layer to the first layer. Change to a lower layer of the layer. As a result, the part of the first layer image that overlaps the part of the second layer image does not disappear from the part of the second layer image. That is, the user can surely visually recognize the entire first layer image. Therefore, for example, when a background image is drawn on the second layer after drawing, for example, a character image on the first layer, it is not necessary to pay attention so that a part of the background image does not overlap a part of the character image. Accordingly, it is possible to easily draw an image by bringing the finger or the contact object into contact with the touch panel.

  Further, after drawing a background image on the second layer, for example, when drawing a character image on the first layer, there is no problem even if a part of the background image overlaps with a part of the character image and disappears. Therefore, even if, for example, a character image is drawn on the first layer and then a background image is drawn on the second layer, a character image is drawn on the first layer after drawing a background image on the second layer. Since drawing is easy, the degree of freedom of image drawing can be increased.

  In addition, if the finger or the contact object is separated from the touch panel, the lower layer changing means changes the second layer to the lower layer of the first layer, so that the user changes the second layer to the lower layer of the first layer. In addition, there is no need for a separate operation, and the operability relating to the image is good.

The home appliance of the present invention is

The control device 200 and the operation panel 5 constitute an example of an image input device. The frame display unit 200e is an example of an identification display unit.

  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.

  And the superheated steam supplied in the said heating chamber 13 heats the to-be-heated object 27 mounted in the net | network 40 on the tray 30, Then, the superheated steam is supplied to the steam inlet 15 of the circulation unit 14 on the right wall surface of the heating chamber 13. The air is sucked into the circulation unit 14 from the suction port 28 formed oppositely. 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 39a, 39b, 39c for locking the both ends of the tray 30 are provided in three stages in the vertical direction. ing. 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. In this way, the saturated water vapor drawn from the diagonally 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.

  A part of the preview area PA is surrounded by a frame FR1, and a picture image or a character image drawn in the enlarged drawing area DA is displayed in the frame FR1. That is, the display state in the frame FR1 is automatically synchronized with the drawing state of the enlarged drawing area DA by the display synchronization unit 200e (see FIG. 5). Thus, when a picture image or character image is drawn in the enlarged drawing area DA with the frame FR1 positioned at the left end of the preview area PA, the picture image or character image is automatically set at the left end of the preview area PA. Is displayed. Further, a right arrow RA is displayed on the right side of the frame FR1 in order to make it easy to understand that the frame FR1 can be moved to the right side. In FIG. 10, the frame FR1 is positioned at the left end of the preview area PA. However, when the center of the preview area PA in the left-right direction is selected with the touch of a finger, the screen shown in FIG. 12 is displayed. The frame FR1 is displayed by the frame display unit 200f (see FIG. 5). Further, the drawing range in the enlarged drawing area DA is determined based on the coordinates or range of the frame FR1.

  The images G301, G302, G303, G304, and G305 are filled with black, red, blue, orange, and green. By selecting one of the images G301, G302, G303, G304, and G305, a picture image and a character image can be drawn in the enlarged drawing area DA with the color of the selected image.

  The image G306 includes a pencil picture image, the image G307 includes an eraser picture image, the image G308 includes a picture image in a state where two sheets of paper are overlapped, and the image G309 is “determined”. "Is included.

  Then, immediately after switching from the screen of FIG. 10 to the screen of FIG. 11, the images G301 and G306 are selected without any operation by the user. In order to show this state, the images G301 and G306 are surrounded by frames FR2 and FR3.

  In the screen shown in FIG. 12, the frame FR1 is located at the center in the left-right direction of the preview area PA. In this state, when a picture image or a character image is drawn in the enlarged drawing area DA, the picture image or the character image can be displayed at the center in the left-right direction of the preview area PA. In order to make it easy to understand that the frame FR1 can be moved to the left and right sides, a left arrow LA is displayed on the left side of the frame FR1 and a right arrow RA is displayed on the right side of the frame FR1. . In such a state, when the image G303 is selected by touching a finger, the screen shown in FIG. 13 is displayed. In the above state, images G302, G304, and G305 other than the image G303 can be selected, and images G307, G308, and G309 can also be selected. In other words, regardless of the position of the frame FR1, one of the images G301, G302, G303, G304, and G305 can be arbitrarily selected, and one of the images G306, G307, G308, and G309 can be arbitrarily selected. It is like that.

  In the screen shown in FIG. 13, the frame FR1 is located at the center in the left-right direction of the preview area PA, and the images G303 and G306 are selected. In this state, if a finger is moved while touching a part of the touch panel 62 on the enlarged drawing area DA, a blue line image is displayed in the enlarged drawing area DA. At this time, even if the finger movement speed is too fast, the image drawing control unit 200b (see FIG. 5) displays the image so that the line displayed in the enlarged drawing area DA is not a dotted line but a single line. Control the drawing of. Further, when the finger is moved so that the trajectory of the contact movement of the finger becomes “A”, a blue character image CG1 indicating “A” is displayed in the enlarged drawing area DA as shown in FIG.

  In the screen shown in FIG. 14, a blue character image CG2 corresponding to a reduced image of the blue character image CG1 is displayed in the frame FR1. In other words, it can be said that the character image CG2 in the character image 211 is enlarged and displayed in the enlarged drawing area DA. Here, in order to use the layer function, when the image G308 is selected by finger touch, the screen is switched to the screen shown in FIG.

  In the screen illustrated in FIG. 15, the image G308 is surrounded by a frame FR3 to indicate that the image G308 is selected. In addition, images G310 and G311 showing pictures and characters are displayed side by side in the left-right direction above the images G306, G307, G308, and G309. This image G310 includes a picture image in which white paper is superimposed on black paper, and a character image “over”. On the other hand, the image G311 includes a picture image in which black paper is superimposed on white paper, and a character image “being underneath”.

  Further, immediately after switching from the screen in FIG. 14 to the screen in FIG. 15, the image G <b> 310 is selected without any operation by the user. In order to show this state, the image G310 is surrounded by a frame FR4. When the image G308 is selected by finger touch or the image G311 is selected by finger touch, the screen shown in FIG. 16 is displayed.

  In the screen shown in FIG. 16, the image G311 is surrounded by a frame FR4 to indicate that the image G311 is selected. In this state, when the image G308 is selected by finger touch or the image G310 is selected by finger touch, the screen returns to the screen shown in FIG. In addition, when the image G306 is selected by touching a finger in the above state, the screen is switched to the screen shown in FIG.

  In the screen shown in FIG. 17, the images G301, G302, G303, G304, and G305 are again displayed side by side in the left-right direction above the images G306, G307, G308, and G309. At this time, among the images G301, G302,..., G308, the one that has been selected immediately before the start of the layer setting is selected. That is, the images G303 and G306 are selected. When the image G305 is selected by touching a finger in this state, the image is switched to the image shown in FIG.

  In the state shown in FIG. 16, when a finger is moved while touching a part of the touch panel 62 on the enlarged drawing area DA, a green line image LG1 can be drawn as shown in FIG. At this time, since the image G311 of FIG. 16 is selected, a portion where the blue character image CG1 and the green line image LG1 intersect with each other is blue, and the green line image LG1 is below the blue character image CG1. The display looks like Then, by moving the frame FR1 and drawing in the enlarged drawing area DA, as shown in FIG. 20, a green character image CG3 indicating “ji” is displayed on the right side from the center in the horizontal direction of the preview area PA. And a green character image CG4 indicating “no” can be displayed. In such a state, when the image G307 is selected by touching a finger, the screen shown in FIG. 21 is displayed.

  In the screen shown in FIG. 21, the image G312 is surrounded by a frame FR5 to indicate that the image G312 is selected. In addition, images G312 and G313 showing pictures and characters are displayed side by side in the left-right direction above the images G306, G307, G308, and G309. The image G312 includes a picture image of an eraser and a character image “Eraser”. On the other hand, the image G313 includes a dotted-line picture and a character image “All erased”. In this state, if the finger is moved while touching a part of the touch panel 62 on the preview area PA, the blue character images CG1 and CG2 and the green line images LG1 and LG2 can be partially erased. . For example, as shown in FIG. 22, a blue character image CG1 ′ in which a part of “A” disappears and a green line image LG1 ′ in which a part of horizontal line disappears can be displayed in the enlarged drawing area DA. it can. At the same time, the blue character image CG2 ′ corresponding to the reduced image of the blue character image CG1 ′ and the green line image LG2 ′ corresponding to the reduced image of the green line image LG1 ′ are automatically included in the frame FR1. Can be displayed. In such a state, when the image G313 is selected by touching a finger, the screen shown in FIG. 23 is displayed.

  In the screen shown in FIG. 23, the image G313 is surrounded by a frame FR5 to indicate that the image G313 is being selected. In this state, when a finger touches the portion of the touch panel 62 that overlaps the enlarged drawing area DA, all of the character images CG1 ′ and CG2 ′ and the line images LG1 ′ and LG2 ′ are erased to a state as shown in FIG. it can. That is, the entire image can be erased with one finger touch. In this state, when a part of the touch panel 62 that overlaps the right end of the preview area PA is touched with a finger, the frame FR1 is moved to the right end of the preview area PA as shown in FIG. 25, and an enlarged image of the green character image CG4 is displayed. A corresponding green character image CG5 is displayed in the enlarged drawing area DA. Even in this state, all of the character images CG4 and CG5 can be erased by one touch of a finger, and the state shown in FIG. 26 can be obtained.

  As described above, since the image drawn in the enlarged drawing area DA is previewed in the preview area PA, the image can be drawn in the enlarged drawing area DA while confirming the positional relationship and the size relationship with other images. . Therefore, for example, as shown in FIG. 27, a character image of “Grandma's Satoimo” with a flower image as a background can be drawn on the top of the screen in a balanced manner. That is, it is possible to maintain the balance of the entire image of “Grandma's Satoimo”.

  Further, since the drawing area of the enlarged drawing area DA is larger than the drawing area of the preview area PA, it is easy to input an image into the enlarged drawing area DA.

  Further, since the display state in the frame FR1 is automatically synchronized with the drawing state of the enlarged drawing area DA, an operation only for synchronizing the display state in the frame FR1 with the drawing state of the enlarged drawing area DA is not necessary. is there. Therefore, the operation burden on the user can be reduced.

  In addition, since the portion corresponding to the enlarged drawing area DA in the preview area PA is surrounded by a frame FR1, it is easy and accurate to estimate where the image drawn in the enlarged drawing area DA is located in the completed image. it can.

  In addition, since the portion corresponding to the enlarged drawing area DA in the preview area PA is surrounded by the frame FR1, it is possible to make the portion visually understandable.

  Further, since the frame FR1 can be moved to an arbitrary position in the preview area PA, the frame FR1 is moved to an arbitrary position in the preview area PA, and an image is drawn or drawn at the position. The image can be modified.

  FIG. 27 is a diagram showing an example of a final screen for inputting a menu name. This final screen is a screen displayed by performing the operation as described above, drawing a character image of “Grandma's Satoimo” with a flower image as a background, and then selecting the image G309 with the touch of a finger. It is.

  In the final screen, images G314 (“Yes”) and G315 (“No”) are displayed side by side in the left-right direction at the center. In addition, there is a final confirmation area CA at the upper end of the final screen so that a character image of “Grandma's sweet potato” with a flower picture image as a background can be finally confirmed in the final confirmation area CA. . Here, when the image G314 is selected by touching the finger, the screen is switched to the “original menu registration” screen shown in FIG. 28, while when the image G315 is selected by touching the finger, the screen is switched to the previous screen.

  In FIG. 28, images G31 '("menu name", "registration"), G32, G33, G34' ("registration complete") are displayed side by side in the vertical direction. This image G34 'has a darker character color than the image G34 (see FIG. 10), indicating that it can be selected. Also, below the image G34 ', images G35' ("delete") and G36 '("move this menu to the top") are displayed side by side in the left-right direction. The images G35 'and G36' indicate that the character color is different from the background color and is in a selectable state.

  Then, after the image G33 is selected by finger touch and the heating condition is registered, when the image G12 in FIG. 8 is selected by finger touch, the original menu screen shown in FIG. 29 is displayed.

  On the upper end portion of the original menu screen, as shown in FIG. 29, “Grandma's Satomo” with a background of a picture of a flower, which is confirmed by selecting an image G314 (see FIG. 27) with the touch of a finger. "Is displayed. On the lower side of the character image, images G21 ("water oven", "bread shoe"), G22 ("no preheating", "first stage"), G23 ("160 ° C"), G24 (" 23:00 ") are displayed side by side in the vertical direction. Further, images G16, G19 (“Determination”), G18 are displayed side by side in the left-right direction below the image G24. When this image G19 is selected by touch of a finger, heating cooking along the display content of the original menu screen can be performed.

  In addition, although 25 screens such as the above-mentioned original menu screen can be registered, as shown in FIG. 29, by displaying a character image of “Grandma's Satoimo” with a flower picture image as a background, the user can Since the original menu can be recalled at a glance, it is possible to greatly reduce the possibility that the cooking of the original menu which is not desired is selected.

  30A and 30B are flowcharts for explaining the screen control operation of the control device 200. FIG. This screen control starts in response to an operation performed by the user to register / change the menu name.

  When the screen control process starts, it is first determined in step S101 in FIG. 30A whether or not the first layer is selected. If it is determined in step S101 that the first layer is selected, the process proceeds to step S102. If it is determined that the first layer is not selected, the process proceeds to step S201 in FIG. 30B. Note that “determining whether or not the first layer is selected” in step S101 means the image G310 (see FIGS. 15 and 16), the image G306 (see FIGS. 15 and 16), or the image G308 (see FIG. 15). , Refer to FIG. 16).

  Hereinafter, processing when the process proceeds from step S101 to step S102 will be described.

  In step S102, it is determined whether or not the touch panel 62 has been touched. If it is determined in step S102 that the touch panel 62 has been touched, the process proceeds to step S103. If it is determined that there is no touch on the touch panel 62, the process proceeds to step S111. In step S111, it is determined whether or not a drawing end operation has been performed. If it is determined in step S111 that the drawing end operation has been performed, the screen control ends. If it is determined that there is no drawing end operation, the process returns to step S101. Note that “determining whether or not the touch panel 62 has been touched” in step S <b> 102 means determining whether or not a finger or a contact object has touched the enlarged drawing area DA. Further, “determining whether or not there has been a drawing end operation” in step S111 means determining whether or not the image G309 (see FIGS. 15 and 16) has been selected.

  Next, after drawing on the first layer so that the locus of contact movement of the finger or the contact object is displayed in the enlarged drawing area DA in step S103, the process returns to step S101.

  Hereinafter, processing when the process proceeds from step S101 to step S201 in FIG. 30B will be described.

  In step S201, it is determined whether the second layer is selected. If it is determined in step S201 that the second layer is selected, the process proceeds to the next step S202. If it is determined that the second layer is not selected, the process returns to step S101 in FIG. 30A. Note that “determining whether or not the second layer is selected” in step S201 means determining whether or not the image G311 and the image G306 or the image G308 are selected. . For example, immediately after the screen is switched by selecting the image G306 on the screen of FIG. 15, the determination result of step S201 is “NO”. Further, immediately after switching from the screen of FIG. 16 to the screen of FIG. 17 by selecting the image G306, the determination result of step S201 is “YES”.

  Next, in step S202, the hierarchy of the second layer is changed so that the second layer is higher than the first layer.

  Next, in step S203, it is determined whether or not the touch panel 62 has been touched. If it is determined in step S203 that there is a touch on the touch panel 62, the process proceeds to the next step S204. If it is determined that there is no touch on the touch panel 62, the process proceeds to step S211. In this step S211, it is determined whether or not there has been a drawing end operation. If the determination result is “There has been a drawing end operation”, the screen control is ended, while the determination result is “drawing”. If there is no “end operation”, the process returns to step S101 in FIG. 30A to determine whether or not the first layer is selected. Note that “determining whether or not the touch panel 62 has been touched” in step S203 means determining whether or not a finger or a contact object has touched the enlarged drawing area DA.

  Next, in step S204, drawing is performed on the second layer so that the locus of contact movement of the finger or the contact object is displayed in the enlarged drawing area DA.

  Next, in step S205, it is determined whether or not the touch on the touch panel 62 has been released. If it is determined in step S205 that the touch on the touch panel 62 has not been released, the process returns to step S204, whereas if it is determined that the touch on the touch panel 62 has been released, the process proceeds to the next step S206. Note that “determining whether or not the touch on the touch panel 62 has been released” in step S205 means determining whether or not the finger or the contact object has separated from the enlarged drawing area DA.

  Next, in step S206, the hierarchy of the second layer is changed so that the second layer is lower than the first layer.

  Next, in step S207, it is determined whether or not there has been a drawing end operation. If it is determined in step S207 that a drawing end operation has been performed, the screen control ends. If it is determined that there is no drawing end operation, the process returns to step S101 in FIG. 30A. Note that “determining whether or not there has been a drawing end operation” in step S207 means determining whether or not the image G309 has been selected.

  In the present embodiment, step S201 is used as an example of the selection determination unit, step S202 is set up as an example of the upper hierarchy changing unit, step S203 is set up as an example of the contact determination unit, and step S204 is set up as an example of the image drawing unit. Further, step S205 is used as an example of the separation determination unit, and step S206 is used as an example of the lower hierarchy changing unit.

  As described above, when it is determined in step S201 that the second layer is selected, the second layer is changed to an upper layer of the first layer in step S202. In this state, when the finger or the contact object touches the touch panel 62, the trajectory of the finger or the contact object is drawn on the second layer. Even if they overlap with each other, some data of the first layer image remains without being erased. Therefore, since it is not necessary to draw while paying attention to the image of the first layer, drawing can be easily performed.

  Further, if the drawing on the second layer is not performed before or after the drawing on the first layer, the drawing on the second layer cannot be easily performed. Therefore, the degree of freedom of drawing in the enlarged drawing area DA is high.

  If it is determined in step S205 that the finger or the touched object is separated from the touch panel, step S206 changes the second layer to a lower layer of the first layer, so that the user changes the second layer to the first layer. There is no need to perform a separate operation to change to a lower hierarchy, and the operability related to drawing is good.

  As a specific example, as shown in FIG. 16, when the screen of FIG. 17 is displayed by selection of the image G306 in a state where the frame FR4 surrounds the image G311, the pointer is displayed on the enlarged drawing area DA. Or, when the contact object is slid, while the finger or the contact object is sliding, it looks as if the trajectory of the finger or the contact object is drawn on “A” drawn on the first layer. When the finger or the contact object is moved away from DA, it appears as if the trajectory has moved under “A”. Therefore, drawing can be performed easily and comfortably without paying attention so that the finger or the contact object does not overlap with the “A” character of the first layer.

  In addition, since the drawing is easy to perform before or after the drawing of “A” in the first layer, the degree of freedom of drawing by the locus is high.

  In addition, the operability associated with drawing is high because it appears as if the trajectory has moved under “A” simply by separating the finger or the contact object.

  In the above embodiment, the portion corresponding to the drawing area DA in the preview area PA is surrounded by the frame FR1, but the portion may be colored differently from other portions or blinked.

  In the above embodiment, the frames FR2, FR3, FR4, and FR5 are used to indicate which of the images G301 to G305, G306 to G308, G310, and G311, and the images G312 and G313 are selected. The selected image may be displayed slightly larger than the unselected image, or only the unselected image may be displayed through.

  In the above embodiment, two layers can be created, but three or more layers may be created.

  Although specific embodiments and modifications of the present invention have been described, the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made within the scope of the present invention. For example, home appliances (such as rice cookers, refrigerators, vacuum cleaners, television receivers, air conditioners, electric razors, and lighting fixtures), mobile phones, toys, etc. other than the heating cooker include the control device 200 and the operation panel 5 or Similar ones may be provided.

  Examples of the cooking device of 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 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 where the volume% of oxygen is 10% or less (for example, 0.5 to 3%) in the heating chamber.
