  Embodiments of the present invention will be described below with reference to the drawings. Drawing 1 is a front view showing a cooking appliance of one embodiment. The cooker 1 is provided with a door 2 that opens and closes the front surface of a heating chamber (not shown). The door 2 is formed with a window portion 2a for visually recognizing the inside of the heating chamber, and a handle 2b held by the user is provided above the window portion 2a. An operation panel 9 which will be described in detail later is provided on the right side of the window 2a.

  FIG. 2 is a block diagram showing the configuration of the cooking device 1. The cooker 1 includes a control unit 3 that is provided on the back surface of the operation panel 9 and controls each unit. A magnetron 4, an antenna motor 5, a temperature sensor 6, a storage unit 7, an operation unit 10, and a display unit 20 are connected to the control unit 3.

  The magnetron 4 generates a high frequency, and the cooked food is cooked by the high frequency supplied to the heating chamber. The antenna motor 5 drives an antenna (not shown) provided in the heating chamber, and the high frequency supplied to the heating chamber is made uniform by the antenna. The temperature sensor 6 detects the temperature in the heating chamber, and determines the cooking end time, abnormal heating, or the like based on the temperature detected by the temperature sensor 6.

  The memory | storage part 7 consists of ROM and RAM, and the database of a cooking program and a cooking menu is memorize | stored. In addition, the storage unit 7 temporarily stores calculations by the control unit 3. The operation unit 10 and the display unit 20 are provided on the operation panel 9. The operation unit 10 performs cooking operations such as selection of a cooking menu, setting of cooking conditions, and an instruction to start cooking. The display unit 20 is composed of a liquid crystal panel or the like, and the operation screen is switched and displayed, and the progress of cooking is displayed.

  The operation unit 10 includes a mechanical hard key 11 and a capacitive touch panel 15. The mechanical hard key 11 is formed by a tact switch having a contact. The capacitive touch panel 15 is provided on the surface of the display unit 20, and detects the presence / absence of an operation by capturing a change in capacitance due to contact between the fingertip and the surface of the display unit 20 with a weak current. The sensitivity of the touch panel 15 is set in advance in a predetermined range corresponding to the capacitance of a normal person. When the detected current is larger than the set threshold, it is determined that the fingertip is touched, and when the detected current is smaller than the threshold, it is determined that the fingertip is not touched.

  FIG. 3 shows a front view of the operation panel 9. A display unit 20 is arranged at the upper part of the operation panel 9, and a plurality of hard keys 11 are arranged at the lower part. The hard key 11 includes a plurality of button keys 12 having tact switches and a rotatable dial key 13. The button keys 12 include a manual heating key 12a, a return key 12b, a cancel key 12c, and a start key 12d.

  The manual heating key 12a instructs to shift to an operation screen for manually setting cooking conditions. The return key 12b instructs to move the operation screen displayed on the display unit 20 to the previous screen. The cancel key 12c instructs to cancel the input operation. The start key 12d instructs the start of cooking.

  FIG. 4 is a flowchart showing the operation of the cooking device 1 at the start of cooking. In step # 11, it is determined from the current value detected when the user touches the touch panel 15 whether the sensitivity of the touch panel 15 is lowered. If the sensitivity of the touch panel 15 has not decreased, the process proceeds to step # 13. If the sensitivity of the touch panel 15 decreases and the detected current becomes close to the threshold value, there is a possibility of erroneous detection. For this reason, it is notified by the display unit 20 in step # 12 and prompted to adjust the sensitivity of the touch panel 15 in an adjustment mode described later.

  In step # 13, it is determined whether or not the cancel key 12c included in the hard key 11 has been pressed for a long time. If the cancel key 12c has not been pressed for a long time, the process proceeds to step # 15. When the cancel key 12c is pressed for a long time, the process proceeds to an adjustment mode described later in step # 14. An instruction to shift to the adjustment mode may be given by an operation with another hard key 11.

  In step # 15, it is determined whether cooking conditions have been set. The cooking conditions are set by selecting a desired cooking menu on the touch panel 15 or inputting cooking conditions on the touch panel 15 after pressing the manual heating key 12a. When cooking conditions are not set, it returns to step # 11 and steps # 11- # 15 are performed repeatedly.

  If cooking conditions are set, it will transfer to step # 16 and will wait until there is an instruction | indication of the cooking start by pressing down the start key 12d. When the start key 12d is operated, the process proceeds to step # 17, and cooking is performed under the set cooking conditions.

  FIG. 5 is a flowchart showing the operation in the adjustment mode. The adjustment mode includes a manual mode and an automatic mode, and one of them is set in advance by the user. In the manual mode, the user manually adjusts the sensitivity of the touch panel 15, and in the automatic mode, the control unit 3 automatically adjusts the sensitivity of the touch panel 15.

  When the adjustment mode is entered, it is determined in step # 20 whether or not the manual mode is selected. If the manual mode is set, the process proceeds to step # 21. In step # 21, the process waits until the dial key 13 is rotated. When the dial key 13 is rotated, the sensitivity of the touch panel 15 is varied in accordance with the amount of rotation in step # 22.

  In step # 23, a confirmation screen for confirming the sensitivity of the touch panel 15 is displayed on the display unit 20. In step # 24, it is determined whether or not the return key 12b has been operated. If the return key 12b is not operated, the process proceeds to step # 25. In step # 25, it is determined whether or not an operation on the touch panel 15 is detected by touching the fingertip on the confirmation position on the confirmation screen.

  When the operation of the touch panel 15 is not detected, the process returns to step # 24, and steps # 24 and # 25 are repeated. Thereby, it waits until operation of the return key 12b or the touch panel 15 is performed. If the touch panel 15 does not react even when the fingertip is touched, the sensitivity adjustment is not appropriate, and the return key 12b is operated. Then, returning to step # 21, the sensitivity of the touch panel 15 is changed by operating the dial key 13 again.

  When it is detected that the touch panel 15 has been operated, the process proceeds to step # 26. In step # 26, an adjustment completion screen indicating completion of sensitivity adjustment is displayed on the display unit 20. At this time, the sensitivity after adjustment is displayed on the adjustment completion screen by a diagram or the like that can compare the threshold value of the current value of the touch panel 15 and the detected current. On the adjustment completion screen, an “OK” button for exiting the adjustment mode and a “Cancel” button for readjusting the sensitivity are displayed.

  In step # 27, it is determined whether or not the “OK” button has been pressed. If the “OK” button is pressed, the process returns to the flowchart of FIG. If the “cancel” button is pressed, the process returns to step # 21, and the sensitivity of the touch panel 15 is readjusted.

  If the automatic mode is set, the process proceeds to step # 31 based on the determination in step # 20. In step # 31, a confirmation screen for confirming the sensitivity of the touch panel 15 is displayed on the display unit 20. In step # 32, it is determined whether or not it has been detected that the touch panel 15 has been operated. If the operation of the touch panel 15 is not detected, the process proceeds to step # 33.

  In step # 33, it is determined whether any of the hard keys 11 has been operated. If the hard key 11 is not operated, the process returns to step # 32, and steps # 32 and # 33 are repeated.

  If the touch panel 15 has low sensitivity and is not detected even if the fingertip is touched, the control unit 3 cannot determine whether the fingertip is touched or separated. For this reason, the user operates the hard key 11 with another finger or another hand while the fingertip is touching the confirmation position on the confirmation screen. As a result, the control unit 3 is instructed to touch the touch panel 15 with a fingertip, and the process proceeds to step # 34. If at least one hard key 11 is arranged in the vicinity of the confirmation position on the confirmation screen, an instruction by the hard key 11 can be easily performed.

  Note that a message or the like prompting the touch panel 15 to touch the fingertip may be displayed on the confirmation screen, and the instruction of the touch of the fingertip on the touch panel 15 by the hard key 11 may be omitted. For example, a message such as “Please touch your fingertip by 5 seconds and leave it for 10 seconds” on the confirmation screen and a progress bar may be displayed. Thereby, the sensitivity adjustment can be performed between 5 seconds and 10 seconds after the message is displayed.

  In step # 34, the threshold value of the current value of the touch panel 15 is appropriately varied while the user's fingertip is touching. In step # 35, in step # 35, an adjustment completion screen indicating completion of sensitivity adjustment is displayed on the display unit 20 for a predetermined time. Then, the process returns to the flowchart of FIG.

  According to the present embodiment, the operation shifts to an adjustment mode in which the sensitivity of the capacitive touch panel 15 is adjusted by operating the hard key 11, so that the user's fingertip is wet or the surface of the touch panel 15 has oil stains. In this case, the sensitivity of the touch panel 15 can be adjusted even when the touch panel 15 does not react. Therefore, the convenience of the cooking device 1 can be improved.

  In addition, since the sensitivity of the touch panel 15 is changed by operating the dial key 13 which is the hard key 11 in steps # 21 and # 22, the sensitivity of the touch panel 15 can be easily adjusted even when the touch panel 15 does not react. it can.

  Further, since the button key 12 for shifting to the adjustment mode and the dial key 13 for changing the sensitivity of the touch panel 15 are provided, the operability at the time of shifting to the adjustment mode and during the adjustment mode can be improved.

  In step # 34, the sensitivity of the touch panel 15 is changed when the fingertip touches the touch panel 15 in the adjustment mode. Therefore, the control unit 3 can automatically adjust the sensitivity.

  Further, since the touch of the fingertip on the touch panel 15 is instructed by the operation of the hard key 11 in step # 33, it is possible to simply instruct the control unit 3 that the fingertip has been touched even when the touch panel 15 does not react. it can.

  In the present embodiment, the food is heated by high frequency, but a cooker that heats the food by hot air or steam may be used.

  According to this invention, it can utilize for the cooking appliance provided with the touch panel.
