The control device 5 includes the storage part 52 for storing a plurality of image data relating to heating of the heated object, an image superposing part 61 for displaying the plurality of images on the color liquid crystal panel while superposing the images to each other by using the plurality of image data, and a transmittance changing part 62 for changing transmittance of the plurality of images on the basis of the signal from the touch panel.

Description

  The present invention relates to a cooking device.

  Conventionally, as a cooking device, there is one in which a display unit is provided on the front surface of a casing as described in JP-A-2002-349858 (Patent Document 1). A plurality of operation units operated by the user are also provided on the front surface of the casing.

  The display unit displays an image corresponding to the data stored in the storage unit in the casing. This image is changed according to the operation of the operation unit.

  In the above-mentioned conventional cooking device, for example, when the image of the start key is displayed on the display unit and the image can be selected by the operation unit, it is not necessary to provide the start key on the front surface of the casing, thereby reducing the manufacturing cost. It is preferable because it is possible. In this case, when the image of the start key is selected, it is more preferable that the display state (for example, color) of the image is changed because it is possible to visually confirm that the image has been selected.

  However, if the number of display states of the image is increased, the same number of image data as the number of display states needs to be stored in the storage unit in advance. For example, if a red image, a yellow image, and a blue image are displayed on the display unit, it is necessary to store data of these three images in the storage unit in advance.

  Therefore, when the number of display states of the image displayed by the display unit is increased, there arises a problem that the capacity of the storage unit is compressed.

  The above problem may be solved by increasing the capacity of the storage unit, that is, by using a large-capacity storage unit, but this solution causes a new problem of increased manufacturing costs.

JP 2002-349858 A

  Then, the subject of this invention is providing the heating cooker which can reduce the compression of the capacity | capacitance of a memory | storage part and can prevent the increase in manufacturing cost in addition.

In order to solve the above problems, the heating cooker of the present invention is
A casing,
A heating chamber provided in the casing and containing an object to be heated;
An operation unit operated by a user to heat the object to be heated;
A display unit for displaying a plurality of images related to heating of the object to be heated;
A control device that receives the signal output from the operation unit and controls the display of the display unit,

Using the data of the plurality of images, an image superimposing unit that superimposes the plurality of images on each other and displays them on the display unit;
And a transmittance changing unit that changes at least one transmittance of the plurality of images based on a signal from the operation unit.

  According to the above configuration, the image superimposing unit superimposes a plurality of images on the display unit using the data of the plurality of images in the storage unit. The transmittance changing unit changes at least one transmittance of the plurality of images based on a signal from the operation unit. Thereby, the number of display states of the images displayed on the display unit can be made larger than the number of images to be superimposed. Therefore, even if the data of the plurality of images stored in the storage unit is reduced, the number of display states of the images displayed on the display unit can be increased, so that the storage capacity can be reduced.

  Further, since the compression of the capacity of the storage unit can be reduced, it is not necessary to increase the capacity of the storage unit, so that an increase in manufacturing cost can be prevented.

In the heating cooker of one embodiment,
The multiple images are
A first image that includes at least one of a character, a picture, and a symbol; and a second image that is a plain that serves as a background for at least one of the character, the picture, and the symbol;
The image superimposing unit superimposes the first image and the second image on the display unit.

  According to the embodiment described above, the image superimposing unit superimposes the first image and the second image on the display unit, so that the display unit is plain with at least one of characters, pictures, and symbols. An image including the background of the image can be displayed. At this time, by changing the transmissivity of the first and second images, at least one of characters, pictures, and symbols and a plain background are included without greatly increasing the amount of data stored in the storage unit. The display state of the image can be increased.

  In addition, since the second image is plain, even if the first image and the second image are overlapped with each other, the visibility of characters, pictures, and symbols included in the first image is not adversely affected.

In the heating cooker of one embodiment,
When the image superimposing unit superimposes the first image and the second image on the display unit and displays the first image and the second image on the display unit, the transmittance changing unit is configured to output the first image based on a signal from the operation unit. The transmittances of the first and second images are changed so that the transmittance of the first image is lower than the transmittance of the second image.

  According to the embodiment, when the image superimposing unit superimposes the first image and the second image on the display unit, the transmittance changing unit is based on a signal from the operation unit. Since the transmittance of the first and second images is changed so that the transmittance of the first image is lower than the transmittance of the second image, the visibility of at least one of characters, pictures, and symbols is visible Can be prevented.

In the heating cooker of one embodiment,
The first image and the second image have different hues.

  According to the embodiment, since the hues of the first image and the second image are different from each other, it is possible to give the second image a color that makes the image of the heating of the object to be heated.

In the heating cooker of one embodiment,
The first image includes only at least one of the characters, pictures, and symbols.

  According to the embodiment, since the first image includes only at least one of a character, a picture, and a symbol, at least one of the character, the picture, and the symbol can be changed only by changing the transmittance of the second image. The display state of an image including at least one of characters, pictures and symbols and a plain background can be changed without adversely affecting one visibility.

In the heating cooker of one embodiment,
The display unit can perform color display.

  According to the embodiment, since the display unit can perform color display, the number of display states of images that can be displayed on the display unit can be increased.

In the heating cooker of one embodiment,
At least a part of the operation unit is a touch panel that covers the display unit.

  According to the embodiment, since at least a part of the operation unit is a touch panel that covers the display unit, for example, the number of keys provided in the casing can be reduced, so that the manufacturing cost can be reduced.

  According to the heating cooker of the present invention, the control device causes the display unit to display a plurality of images superimposed on each other using the storage unit storing the data of the plurality of images and the data of the plurality of images. By having an image superimposing unit and a transmittance changing unit that changes at least one transmittance of a plurality of images based on a signal from the operation unit, the transmittance changing unit is based on a signal from the operation unit. Since at least one transmittance of the plurality of images is changed, the number of display states of the images displayed on the display unit can be made larger than the number of images to be superimposed. Therefore, even if the data of the plurality of images stored in the storage unit is reduced, the number of display states of the images displayed on the display unit can be increased. As a result, the capacity of the storage unit can be reduced.

  Further, since the compression of the capacity of the storage unit can be reduced, it is not necessary to increase the capacity of the storage unit, so that an increase in manufacturing cost can be prevented.

  FIG. 6 is a diagram showing an initial screen of the color liquid crystal panel 95. This initial screen is a screen that is first displayed on the color liquid crystal panel 95 after a power plug (not shown) of the cooking device is inserted into an outlet.

  On the initial screen of the color liquid crystal panel 95, small images G1 to G8 are displayed in a selectable manner. The small image G1 is an image to be selected when milk or sake is warmed to an appropriate temperature, and includes pictures of cups and sake bottles, and characters “milk” and “sake kan”. The small image G2 is an image to be selected when warming a cold dish or the like, and includes a picture of a tea bowl and a shrimp fried food and a character “warming up”. The small image G3 is an image that should be selected when making a steamed food or boiled food, and includes a picture of a pot and steamed rice, and characters “steamed and boiled”. The small image G4 is an image to be selected when searching for a desired dish from more than 300 kinds of dishes in the dish collection, and includes a picture of a book and characters “select from a dish collection”. The small image G5 is an image to be selected when thawing frozen foods and the like, and includes a picture of fish and snow crystals and the characters “defrost”. The small image G6 is an image to be selected when making the grilled food and the fried food, and includes a picture of roast chicken and bread, and letters “baked and fried”. The small image G7 is an image that should be selected when the user wants to use the health support menu, and includes a picture that makes an image of a healthy person and characters of “health support menu”. The small image G8 is an image to be selected when registering well-made dishes, and includes a picture of a push pin and characters of “menu that is often made”.

  The small images G1 to G8 are not selected, and the color of characters and pictures is black, and the color of the part other than the characters and pictures (background part) is yellow. In this state, when the user touches a part of the touch panel 96, a small image (any one of the small images G1 to G8) overlapping the part is selected, and the screen of the color liquid crystal panel 95 is initially displayed. Switch from one screen to another. Here, when the user touches a part of the touch panel 96, the color of the small image overlapping the part changes. Specifically, among the small images G <b> 1 to G <b> 8, only the image overlapping the user's finger is a blackish character or picture, and the color of the part other than the character or picture (background part) is ocher. It becomes yellow close to the color. This state is maintained while the user's finger is in contact with part of the touch panel 96. When the user's finger is removed from a part of the touch panel 96, the color liquid crystal panel 95 automatically displays the other screen. For example, when the user touches a part of the touch panel 96 that overlaps the small image G2, the small image G2 changes to a small image G2 'as shown in FIG.

  FIG. 8 is a schematic diagram for explaining the configuration of the small images G2 and G2 '.

  The image superimposing unit 61 superimposes the large image G102 including the small image G2 on the large image G101 including the small image G9 and displays it on the color liquid crystal panel 95. The transmittance of the large images G101 and G102 can be changed.

  The small image G9 is a brown solid small image that does not include characters or pictures, and is superimposed under the small image G2.

  The transmittance changing unit 62 changes the transmittance of the large images G101 and G102 based on a signal from the touch panel 96. For example, when the small image G2 is in a non-selected state (when not touched), the transmittance changing unit 62 sets the transmittance of the large image G101 to 100% and the transmittance of the large image G102 to 0%. On the other hand, when the small image G2 is selected (when touched), the transmittance changing unit 62 sets the transmittance of the large image G101 to 40% and the transmittance of the large image G102 to 60%.

  In superimposing the large image G101 and the large image G102, the image superimposing unit 61 may use, for example, an alpha blending method. When this alpha blending method is used, the (X, Y) RGB values of the coordinates of the large image G101 are (r1, g1, b1), and the RGB values of the coordinates (X, Y) of the large image G102 are (r2, g2). , B2), the RGB values (r, g, b) after the large image G101 and the large image G102 are superimposed are calculated by the following equations (1) to (3).

r = r1 × (1−α) + r2 × α (1)
g = g1 × (1−α) + g2 × α (2)
b = b1 × (1−α) + b2 × α (3)
Α (0 ≦ α ≦ 1) is a value indicating the degree of transmission of the large image G102. When α is 1, the large image G102 is completely opaque, and when α is 0, the large image G102 is displayed. Becomes completely transparent. The small image G2 in FIG. 6 is obtained when α is set to 1, while the small image G2 ′ in FIG. 7 is obtained when α is set to 0.4.

  The small image G36 of the large image G123 is a light gray plain background small image that does not include characters or pictures. In addition, “>” and “Next” of the large image G126 overlap on the small image G36.

  The transmittance changing unit 62 changes the transmittance of the large images G125 and G126 based on a signal from the touch panel 96. For example, the transmittance changing unit 62 sets the transmittance of the large image G125 to 30% while setting the transmittance of the large image G126 to 0%, thereby obtaining the small image G33 of FIG.

  According to the cooking device configured as described above, the image superimposing unit 61 superimposes the large image G102 including the small image G2 on the large image G101 including the small image G9 and causes the color liquid crystal panel 95 to display the image. At this time, when the transmittance changing unit 62 changes the transmittance of the large image G102, the color liquid crystal panel 95 can display the small images G2 and G2 ′, and the display state is different from the small images G2 and G2 ′. Multiple small images can also be displayed.

  As described above, if the two data of the large images G101 and G102 are stored in the storage unit 52 in advance, it is possible to display a small image in three or more display states on the color liquid crystal panel 95. By reducing the amount of image data stored in the storage unit 52, it is possible to reduce the capacity of the storage unit 52.

  In addition, since the compression of the capacity of the storage unit 52 can be reduced, it is not necessary to increase the capacity of the storage unit 52, so that an increase in manufacturing cost can be prevented.

  The effect of reducing the above-described compression of the capacity of the storage unit 52 and the effect of preventing an increase in manufacturing cost are similarly achieved in the small images G1, G3-8, G11, G12, and G31 to G33.

  Further, in the screen of FIG. 9, in response to the user selecting the small image G11, the transmittance changing unit 62 changes the transmittance of the large image G113 while maintaining the transmittance of the large image G114 at 0. Therefore, it is possible to change the display state of the small image G11 while maintaining good visibility of the characters “room temperature refrigeration” and “frozen”.

  Further, since the entire small image G31 is very light gray on one screen of FIG. 12, the user can intuitively determine that the small image G31 cannot be selected. Therefore, it is possible to prevent the user from getting lost about the operation of the cooking device.

  Further, since the color liquid crystal panel 95 can display in color, the number of display states of images that can be displayed on the color liquid crystal panel 95 can be increased.

  Further, since the touch panel 96 is used, the number of keys provided on the operation panel 35 can be reduced, for example, so that the manufacturing cost can be reduced.

However, as shown in FIG. 16, on the large image G101, a large image G103 including the small image G10, and a large image G104 including only a black shrimp fly picture and a black “warming” character. Small images G2 and G2 ′ may be obtained by overlapping in this order and changing at least one transmittance of the large images G101, G103, and G104.

  The small image G10 is a yellow background small image that does not include characters or pictures, and is superimposed under the “warm” character with the shrimp fly picture.

  Note that the large images G101, G103, and G104 are superimposed by the image superimposing unit 61, and the transmittance of the large images G101, G103, and G104 is changed by the transmittance changing unit 62.

Although the images G11 and G11 ′ were obtained, as shown in FIG. 17, the large image G115 including the small image G17, the large image G113, and the large image G114 are superimposed on the large image G111 in this order. The small images G11 and G11 ′ may be obtained by changing at least one transmittance of the large images G111 to G115.

  The small image G17 is, for example, a blue solid small image that does not include characters or pictures, and is superimposed under the small image G14.

  The large images G111 to G115 are overlapped by the image superimposing unit 61, and the transmittance of the large images G111 to G115 is changed by the transmittance changing unit 62.

That is, the color of the small image G14 and the small image G16 may be interchanged. In this case, since the color of the non-selected state of the small image G11 becomes orange, even if the character of the small image G11 is made to image the refrigeration of “room temperature refrigeration”, heating is performed by selecting the small image G11. The user can have an image that can be done.
