In recent years, with the development of electronics, in order to pursue safety and convenience, advanced electronic technology has been applied to the product field of heating cookers. As such high-function cookers become widespread and the number increases, especially in a complex cooker having a plurality of heating sources, various failures and defects may occur due to the complexity of the configuration. is expected. For this reason, it goes without saying that the manufacturer is required not only to perform quality control so as not to cause a failure or failure, but also to respond more promptly and accurately to the failure or failure that has occurred.
[0003]
In view of such a background, when an abnormality occurs in the device, the set thermal power is usually used, for example, by using a display unit having a display element such as an LED or an LCD that allows the user to recognize the operation state of the device. Depending on the type of abnormality, depending on the type of abnormality, the display may be turned on or blinking differently, or if it has a display element that can display numbers and characters such as timer setting time, etc. In addition, a cooking device has appeared that has means for notifying a user of an abnormality of an apparatus by displaying an abnormal state by displaying a number or a character, or by notifying the user of the abnormality by voice or the like.
[0004]
The operation of the conventional cooking device will be described below with reference to the drawings. FIG. 2 is a block diagram showing a configuration of a conventional example.
[0005]
In FIG. 2, 21 is a first heating unit, 22 is a second heating unit, 23 is an operation unit configured by switches and the like for setting the operating states of the first heating unit 21 and the second heating unit 22, and 24. Is a display unit composed of an LED or LCD that displays the operating states of the first heating unit 21 and the second heating unit 22 set by the operation unit 23, and 25 is a first heating unit 21 and a second heating unit. 22 is an abnormality detection means for detecting 22 abnormalities.
[0006]
The operation of the above configuration will be described. When the user operates a switch or the like of the operation unit 23, the operation unit 23 outputs an operation start or set heat power signal to the first heating unit 21 or the second heating unit 22. Receiving this, the first heating unit 21 or the second heating unit 22 starts the heating operation or changes the setting of the thermal power for the heating operation. At the same time, when the first heating unit 21 is heated, for example, when the display unit 24 heats the LED with a display corresponding to the setting state of each heating unit set by the operation unit 23, the first heating unit 21 is heated. At the same time as the “heating” LED for displaying the operation, the “heating” LED among the LEDs such as “weak”, “medium”, and “strong”, which are the initial heating heating power, is lit and displayed.
[0007]
In addition, the display unit 24 has a numeric display element formed of an LCD for the first heating unit 21, and when the timer is set by the operation unit 23, the timer setting time of the first heating unit 21 is set. Is displayed on the numeric display element of the display unit 24. Each time this timer setting key is pressed, the set time can be increased to obtain a desired set time.

For example, when the second heating unit 2 performs timer cooking, first, the “selection” key of the selection means 3a is pressed twice to select the second heating unit 2, and then the “minute” key 12a is pressed. Press until the desired cooking time is reached. In this embodiment, the cooking time is set to 3 minutes by pressing three times. At the same time, the second display unit 6 turns on the “second” LED 6b indicating that the second heating unit 2 is selected, and the number display element 6c displays “3”. Thereafter, when the “OFF / ON” key 8a is pressed, the LED 10a indicating the heating state of the second display area 10 of the first display unit 4 is turned on, and the heating thermal power is within the LED 10b indicating the thermal power setting state. The LED at the “strong” position, which is the initial value, is lit. As the cooking time progresses, the numeric display element 6c displays a value obtained by subtracting the displayed number until it becomes “0”. The second heating unit 2 automatically stops heating when the set cooking time is reached, and the first display unit 4 turns off the LED in the second display area 10, and the second display unit 6 also The display in the third display area 11 is turned off.
[0030]
Next, when an abnormality occurs in the first heating unit 1 or the second heating unit 2, the abnormality detection unit 5 detects the abnormality, and the second display unit 6 performs display corresponding to the abnormality. . For example, in the first heating unit 1, when the temperature detection element provided is destroyed and the temperature cannot be normally detected, the abnormality detection unit 5 detects this abnormality and adds the content of the abnormality. Corresponding abnormality display, in the present embodiment, “H1” is displayed using the LCD 6c capable of displaying a two-digit seven-segment number arranged in the third display area 11 of the second display unit 6, and the second display The “first” LED 6 a representing the corresponding heating unit arranged in the third display region 11 of the display unit 6 is turned on. Similarly, in the second heating unit 2, when the temperature detection element provided is destroyed and the temperature cannot be normally detected, the abnormality detection means 5 detects this abnormality and the contents of the abnormality are detected. "H1" is displayed by using the LCD 6c in this embodiment, and the "second" LED 6b representing the corresponding heating unit arranged in the third display region 11 of the second display unit 6 is displayed. Lights up. Thus, the user can visually recognize which heating unit of the device has an abnormality and what the abnormality is.
[0031]
Further, when the first heating unit 1 is in the timer cooking state, which is the second setting state, the abnormality detection means 5 is abnormal in the second heating unit, the temperature detection element provided in this embodiment is destroyed. When it is detected that the temperature cannot be normally detected, the second display unit 6 displays the display corresponding to the timer operating state of the first heating unit 1 and the second heating unit 2. The display corresponding to the temperature detection abnormal state occurring in is alternately switched in time series and displayed. That is, the remaining time of the timer cooking of the first heating unit 1 using the LCD 6c, “5” indicating 5 minutes in this embodiment, and the “first” LED 6a are lit for a predetermined time, approximately 1 second in this embodiment. Let At this time, the “second” LED 6b is turned off. Immediately after this, the display “5” on the LCD 6c and the “first” LED 6a are turned off, and then “H1” indicating the abnormal temperature detection state of the second heating unit 2 on the LCD 6a and the “second” LED 6b are about 1 Turn on for seconds. By repeating this operation, the remaining cooking time and the abnormal state occurring in the second heating unit 2 are displayed on the second display unit 6 while continuing the timer cooking operation of the first heating unit 1. The user can recognize the progress of the timer cooking of the first heating unit 1 and the temperature detection abnormality of the second heating unit 2 almost simultaneously. In order to improve the visibility, a blank period during which nothing is displayed and turned on may be provided between the timer cooking state display of the first heating unit 1 and the abnormal state display of the second heating unit 2.
[0032]
Alternatively, when the second heating unit 2 is abnormal in temperature detection and “H1” indicating the temperature detection abnormal state of the second heating unit 2 and the “second” LED 6b are lit on the LCD 6a, “select” is selected. When the first heating unit 1 is selected by pressing the key 3a, the LCD 6a displays the "H1" display and the "second" LED 6b lighting display for about 1 second, and then displays the initial value of the timer setting time on the LCD 6c. Then, "1" is displayed and the "first" LED 6a is displayed for about 1 second. This is repeated alternately. Thereafter, each time the “minute” key 12a is pressed, the timer setting time of the first heating unit 1 is incremented by one and displayed.
