摘要： PROBLEM TO BE SOLVED: Not only to separate juice for a cooked object such as meat but also to keep the separate state by storing the juice away from the roasting part of a plate by forming the plate with the roasting part having plural parallel lines of ribs and an oil receiving part continued to the end of an oil drain groove. SOLUTION: A plate 10 is placed on the upper part of a heater 2 and the straight line part of that heater 2 is abutted to a plane abutting part 17. As a result, the straight line part or curved line part of the heater 2 is not directly positioned in a cavity part 16 and the plane abutting part 17. By radiation heat, the cavity part 16 and a roasting part 13 are heated to high temperature. On the rear side of a flat surface 11 formed on both sides in the lengthwise direction of the plate 10 for retaining the warmth of the cooked object, one part of the straight line part of the heater 2 and the curved line part are abutted and heated. In this case, when meat is placed on the roasting part 13 and heated, meat juice out of meat flows through an oil drain groove 15 to the terminal side of the ribs 12 and is stored in an oil receiving part 14. When the meat roasted by the roasting part 13 is not eaten at once, the warmth retaining state is maintained by moving it onto the flat surface.

摘要： PROBLEM TO BE SOLVED: To provide a power supply circuit reducing voltage fluctuation by omitting an expensive power supply transformer by composing the power supply circuit of a rectifier, controller, heater as a voltage drop resistor, and capacitor. SOLUTION: Water is put in a vessel and the power source plug of an electric hot-water heater is inserted to a power source plug. When an AC power source 17 is positive potential, a current flows to a rectifier D1, 1st lead wire 24, capacitor 39, 4th lead wire 37, diode 38, 2nd lead wire 25, rectifier D2 and heater 5 and the voltage at both the terminals of the capacitor 39 starts increasing. At such a time, since the voltage at both the terminals of the capacitor 39 is still low, a controller 33 is turned off. When the voltage at both the terminals of the capacitor 39 gets higher than the Zener voltage of a Zener diode 35, a current flows to a detection circuit 34, a gate current flows to the controller 33, and the controller 33 is turned on. The current flows from the AC power source 17 to the rectifier D1, 1st lead wire 24, controller 33, 2nd lead wire 25, rectifier D2 and heater 5.

摘要： PROBLEM TO BE SOLVED: To prevent a malfunction of switching to an inspection mode in an ordinary operation from occurring by a process wherein a control part conducts an inspection mode being different from the ordinary operational mode when a single key is pushed in a specified on-off pattern at the beginning of energization of electricity and a specified displaying is performed on a displaying part. SOLUTION: When a reboiling key 15 which is a single key is pushed by a specified on-off pattern, a control part 27 is shifted to an inspection mode and when it is shifted to the inspection mode, a temp. holding lamp 32 is turned on regardless of water temp. When it turns to the inspection mode like this, a displaying part 33a performs a specified display and it becomes possible for an inspector to confirm changing to the inspection mode by displaying. It is possible thereby to prevent an erroneous action which is switched to the inspection mode during ordinary operation from occurring without pushing simultaneously a plurality of keys and turning on an electric source with a frequency being different from an ordinary one.

摘要： PURPOSE: To allow the user to safely handle boiling water by controlling to switch off heaters, activate a display to issue a warning sign when sensor temperature reaches a first set level before boiling, and continue to issue the warning sign until temperature drops to a second set level. CONSTITUTION: A temperature sensor 12 in a gas temperature detecting means 20 is connected to a terminal P3 in a control means 18. When temperature detected by the sensor 12 reaches a first set level, e.g. 87 deg.C, or higher, the operational mode is changed over to the temperature-keeping, lamp-blinking mode by switching off a hot-water heater 4, temperature-keeping heater 5 and boiling lamp 25. Instead, a display (temperature-keeping lamp) 24 is started to blink as the warning sign to inform the user that water temperature is high. When gas temperature in the container 2 drops to a second set level, e.g. 85 deg.C, or lower, the display (temperature-keeping lamp) 24 is switched on calling off the blinking warning sign.
