  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.

  When the user presses the manual heating key 73 (shown in FIG. 3) while the initial screen having such a configuration is displayed, the screen of the color liquid crystal panel 61 is changed from the top operation screen to “manual heating” shown in FIG. The screen changes.

  FIG. 8 shows a “manual heating” screen displayed on the color liquid crystal display unit 6. As shown in FIG. 8, this “manual heating” screen displays images G11 to G20 indicating the types of heating in 10 menu display areas (5 × 2) obtained by dividing the main part of the screen. Has been. In FIG. 8, among the 10 menu display areas, the left display area includes an image G11 (“water oven”), an image G12 (“water grill”), an image G13 (“steamed food”), and an image G14 (from the top). "Range"), Image G15 ("To Auto") are displayed, and in the right display area, from the top, Image G16 ("Oven"), Image G17 ("Grill"), Image G18 ("Soft Steaming"), An image G19 (“fermentation”) and an image G20 (“boiled”) are displayed.

  Then, when any one of the images G11 to G20 is selected by touching with a finger, the process proceeds to cooking according to the selected image. When the image G15 ("To automatic") is selected, the screen returns to the top operation screen shown in FIG.

  Next, when image G14 ("range") shown in FIG. 8 is selected by touching with a finger, a screen for setting the microwave power value and heating time of "manual range" shown in FIG. 9 is displayed. Is done.

  In FIG. 9, the upper display area is an image G31 (microwave power value), the right side of the upper display area is an image G32 (inverted V-shaped mark) and an image G33 (V-shaped mark), and the lower display area is The upper row is an image G34 (heating time), and the lower row of the lower display area is an image G35 ("10 minutes"), an image G36 ("1 minute"), an image G37 ("10 seconds"), an image, G38 ("Clear"), the lowermost display area is the image G39 ("Press Start").

  The image G32 (inverted V-shaped mark) and the image G33 (V-shaped mark) are power value setting keys, and these power value setting keys are displayed on the color liquid crystal display unit 6 by the power value setting key display control unit 200d. To do. The image G35 (“10 minutes”), the image G36 (“1 minute”), the image G37 (“10 seconds”), and the image G38 (“clear”) are heating time setting keys. The color is displayed on the color liquid crystal display unit 6 by the heating time setting key display control unit 200a.

  Among the heating time setting keys, the image G35 (“10 minutes”), the image G36 (“1 minute”), and the image G37 (“10 seconds”) are set so that the addition time to be added to the heating time increases stepwise. And an addition key associated with the addition time of “10 minutes,“ 1 minute ”, and“ 10 seconds ”.

  In FIG. 9, the current setting conditions are a microwave power value of 1000 W and a heating time of 3 minutes 00 seconds.

  In the specification of this cooking device, the power value of the microwave is selected from 1000 W, 600 W, 500 W, and 200 W. Here, 1000 W is a power upper limit value, 200 W is a power lower limit value, and the maximum heating time (heating time upper limit value) in the power value of each microwave is as follows.

1000 W: 10 minutes 600 W: 30 minutes 500 W: 30 minutes 200 W: 90 minutes Note that the maximum heating time in the microwave power value is appropriately set depending on the configuration of the heating cooker, and is not limited to this embodiment. Absent.

  In FIG. 9, since the power value of the microwave is already set to 1000 W, the key (first selection key) of the image G32 (reverse V-shaped mark) is invalid and the image G32 (reverse V-shaped). This indicates that the key is invalid by increasing the overall hue. In other words, the power value exceeding 1000 W cannot be set.

  In addition, since the maximum heating time when the microwave power value is 1000 W is 10 minutes, the key of the image G35 ("10 minutes") is invalid, and the color of the entire image G35 ("10 minutes") Indicates that the key is invalid. That is, the heating time exceeding 10 minutes cannot be set.

  In FIG. 9, every time the image G33 (V-shaped mark) is selected by touching, the power value of the microwave is “600W”, “500W”, “200W” in order of the image G31 (microwave power). The display content of (value) changes. When the display content of the image G31 (the power value of the microwave) becomes “600W” and “500W”, the image G32 (inverted V-shaped mark) whose overall color is dark is restored to the original color and is an effective key. It becomes.

  When the display content of the image G31 (microwave power value) becomes “200 W”, the key (second selection key) of the image G33 (V-shaped mark) becomes invalid and the image G33 (V-shaped) This indicates that the key is invalid by darkening the overall color.

  In FIG. 10, since the microwave power value is set to 500 W, the keys of the image G33 (V-shaped mark) and the image G32 (reverse V-shaped mark) are valid. Further, since the maximum heating time is 30 minutes, the key of the image G35 (“10 minutes”) is also effective.

  For example, when the display content of the image G34 (heating time) is the initial value of 00 seconds, the current display content of the image G34 (heating time) is displayed each time the image G35 (“10 minutes”) is touched once. 10 minutes is added to the heating time. Each time the image G36 (“1 minute”) is touched once, 1 minute is added to the current heating time which is the display content of the image G34 (heating time). Each time the image G37 (“10 seconds”) is touched once, the display content of the image G34 (heating time) is added to the current heating time by 10 seconds. Therefore, a desired heating time can be set by combining the heating time setting keys of the image G35 (“10 minutes”), the image G36 (“1 minute”), and the image G37 (“10 seconds”).

  When the image G38 ("Clear") is touched during the setting of the heating time, the heating time that is the display content of the image G34 (heating time) returns to zero.

  In this way, after setting the microwave power value and the heating time condition, when the start key 74 (shown in FIG. 3) is pressed, the range heating starts at the set microwave power value. The heating is finished after elapse of the heating time.

  Next, range thawing will be described.

  When the image G8 ("decompress") is pressed while the top operation screen shown in FIG. 7 is displayed, the screen of the color liquid crystal panel 61 displays the "range decompression" screen shown in FIG. 11 from the top operation screen. To do. In this “range thawing”, frozen foods and the like are thawed using a microwave.

  FIG. 11 shows a range decompression screen at 100 g displayed on the color liquid crystal display unit. As shown in FIG. 11, the “range decompression” screen has an image G41 (food weight) in the central display area, and an image G42 (inverted V-shaped mark) and an image G43 (V-shaped) on the right side of the central display area. ), The upper part of the lower display area is the image G44 (square plate on which the net is placed), the lower part of the lower display area is the image G45 ("Does not use a square plate / amy"), the lower display area The bottom row of is an image G46 ("Press start"). Image G32 (inverted V-shaped mark) and image G33 (V-shaped mark) are food weight setting keys.

  In FIG. 11, the current setting condition is that the food weight is 100 g.

  In the specification of this cooking device, the weight of the ingredients when the range is thawed is selected from 100 g, 200 g, 300 g, 400 g, 500 g, 600 g, 700 g, 800 g, 900 g, and 1000 g.

  In addition, the foodstuff weight at the time of the said range thawing | decompression is suitably set with the structure of a heating cooker, and is not restricted to this embodiment.

  In FIG. 11, since the food weight is set to the initial value of 100 g, the key of the image G43 (V-shaped mark) is invalid and the “V-shaped” of the image G43 (V-shaped mark). By making the color of the portion light and the color of the background dark, the key is invalid. That is, it cannot be set to less than 100 g.

  In FIG. 11, every time an image G42 (inverted V-shaped mark) is touched and selected, the display content of the image G41 (food weight) is displayed every 100 g in the order of the food weight from “200 g” to “1000 g”. change. As shown in FIG. 12, when the display content of the image G41 (food weight) is “200 g”, the image G43 (V-shaped mark) in which the color of the “V-shaped” portion is light and the color of the background is dark is It returns to the original color and becomes a valid key.

  Then, as shown in FIG. 13, when the display content of the image G41 (food weight) becomes “1000 g”, the key of the image G42 (inverted V-shaped mark) becomes invalid, and the image G42 (inverted V-shaped) By marking the “inverted V-shaped” portion of the mark “light” and making the background darker, the key is invalid. In other words, the food material weight exceeding 1000 g cannot be set.

  Next, the screen control operation of the control device 200 will be described with reference to the flowcharts shown in FIGS.

  The screen control shown in FIGS. 14 to 19 is a screen control for the user to set conditions in “range heating” and “range thawing” of manual heating. The screen control is started in a state where the color liquid crystal panel 61 displays the top operation screen shown in FIG.

  On the other hand, if it is determined in step S96 that the upward key (image G42) is not selected, the process proceeds to step S100.

  If it is determined in step S100 that the food material weight Wt is 100 g, the process proceeds to step S104, an invalid display for invalidating the down key (image G43) is performed, and the process returns to step S94. That is, by reducing the hue of the “V-shaped” portion of the image G43 (V-shaped mark) and increasing the hue of the background, this indicates that the key is an invalid key, and setting of less than 100 g cannot be performed.

  If it is determined in step S100 that the food weight Wt is not 100 g, the process proceeds to step S101. If it is determined that the down key (image G43) is selected, the process proceeds to step S103, and 100 g is subtracted from the food weight Wt and the process proceeds to step S104.

  According to the cooking device having the above-described configuration, when the touch panel 62 of the color liquid crystal display unit 6 is operated by the contact of the user's finger (or pen-like object), the control device 200 performs the operation based on the operation signal received from the touch panel 62. A microwave power value and a heating time T are set. At this time, sound is output from the speaker 90 in accordance with the operation signal received from the touch panel 62. The heating chamber 13 is controlled by the control device 200 so that the microwave heating operation is performed with the set microwave power value and the heating time T.

  When the microwave power value and the heating time T shown in the flowcharts of FIGS. 14 to 18 are set by operating the touch panel 62, the controller 200 sets the heating power that is set in advance according to the magnitude of the microwave power value. If it is determined that the heating time T to be set based on the operation signal from the touch panel 62 exceeds the heating time upper limit value corresponding to the current microwave power value using the time upper limit value, the heating time T is set to zero. And a characteristic sound indicating that the heating time T to be set exceeds the upper limit value of the heating time is output to the speaker 90. Thereby, the user can easily recognize that the heating time T to be set at the time of heating by the microwave exceeds the heating time upper limit value, and the operability can be improved.

  Further, when setting the heating time T by the microwave, the heating time setting control unit 200b displays an image G35 representing a plurality of heating time setting keys displayed on the color liquid crystal display unit 6 by the heating time setting key display control unit 200a. The heating time T to be set based on the operation signal from the touch panel 62 due to the contact of the finger (or pen-like object) to G36, G37, and G38 is less than the upper limit value of the heating time corresponding to the current microwave power value. If it is determined, the heating time T to be set is set and displayed on the color liquid crystal display unit 6. On the other hand, when it is determined that the heating time T to be set exceeds the heating time upper limit value corresponding to the current microwave power value, the heating time setting control unit 200b sets the heating time T to zero and sets the color. While being displayed on the liquid crystal display unit 6, the characteristic sound output control unit 200c causes the speaker 90 to output a characteristic sound indicating that the heating time T to be set exceeds the heating time upper limit value. Accordingly, it is possible to easily set the heating time T by touching an image representing a plurality of heating time setting keys displayed on the color liquid crystal display unit 6, and the color liquid crystal display unit during the touch operation. Since the heating time T is displayed in the vicinity of the heating time setting key 6, the user can confirm that the heating time T has exceeded the upper limit of the heating time due to the operation screen of the color liquid crystal display unit 6 and the characteristic sound of the speaker 90. Can be easily recognized.

  Further, as shown in FIG. 9, the heating time setting control unit 200b includes a plurality of addition keys (images G35, G36,. G37), when the addition time corresponding to the key is added to the current heating time T, the key exceeding the heating time upper limit value corresponding to the current microwave power value is invalid (image G35 in FIG. 9). At the same time, the heating time setting key display control unit 200a changes the color of the key (image G35 in FIG. 9) invalidated by the heating time setting control unit 200b among the plurality of keys. Thus, when the addition time corresponding to the key is added to the current heating time T to the current heating time T, the key that exceeds the heating time upper limit value corresponding to the current microwave power value is invalidated, By changing the color of the invalid key to make it easy to distinguish it from other valid keys, the invalid key is not operated and the operability is further improved.

  In addition, images G32 and G33 representing a plurality of power value setting keys for setting the microwave power value are displayed on the color liquid crystal display unit 6 by the power value setting key display control unit 200d. Then, an operation signal from the touch panel 62 due to contact of a finger (or a pen-like object) with the images G32 and G33 representing the plurality of power value setting keys displayed on the color liquid crystal display unit 6 by the power value setting key display control unit 200d. Based on the above, a microwave power value is set within a predetermined range (1000 W to 200 W), and is displayed on the color liquid crystal display unit 6 by the power value setting control unit 200e. This makes it possible to easily set the microwave power value within a predetermined range by operating a plurality of power value setting keys (images G32 and G33).

  Also, as shown in FIG. 9, when the current microwave power value is the power upper limit value, the power value setting control unit 200e invalidates the image G32 (inverted V-shaped mark) that is the first selection key. On the other hand, when the power value of the current microwave is the power lower limit value, the image G33 (V-shaped mark) as the second selection key is set as an invalid key and the image G32 (inverted V-character). In the image G33 (V-shaped mark), the power value setting key display control unit 200d changes the hue of the key that is invalidated by the power value setting control unit 200e. As described above, the key that becomes the operation exceeding the power upper limit value or the operation lower than the power lower limit value of the image G32 (inverted V-shaped mark) and the image G33 (V-shaped mark) is invalidated. By changing the color of the key that has been used to make it easy to distinguish it from other valid keys, the invalid key is not operated and the operability is further improved.

  In the above-described embodiment, the entire color of the image G32 (inverted V-shaped mark) and the image G33 (V-shaped mark) is increased, or the image G42 (inverted V-shaped mark) and the image G43 are displayed. The “inverted V-shaped” and “V-shaped” of (V-shaped mark) are shown to be invalid keys by making the background color darker and lighter. Not exclusively. For example, a combination of hue, lightness, and saturation, contrast, pattern (for example, shading, etc.), etc. may be changed so that they can be distinguished from other valid keys.

  In the above embodiment, the heating time setting keys of the image G35 (“10 minutes”), the image G36 (“1 minute”), the image G37 (“10 seconds”), and the image G38 (“clear”) are set to the heating time. Although displayed on the color liquid crystal display unit 6 by the setting key display control unit 200a, the heating time setting key is not limited to this, and a numeric keypad or the like may be used as the heating time setting key.

  In the above embodiment, the power value setting keys of the image G32 (inverted V-shaped mark) and the image G33 (V-shaped mark) are displayed on the color liquid crystal display unit 6 by the power value setting key display control unit 200d. However, the power value setting key is not limited to this, and a setting key provided for each specifiable power value may be used.

  Moreover, examples of the cooking device according to the present invention include not only an oven range using superheated steam, but also an oven using superheated steam, an oven range not using superheated steam, and an oven not using 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 where the volume% of oxygen is 10% or less (for example, 0.5 to 3%) in the heating chamber.
