Claims

[Claims for Utility Model Registration] (1) A thermostat or thermistor that has a concave or convex portion formed on the top plate surface of an induction heater and is capable of controlling the power supply, turning off, current, and voltage strength on the induction heater side. A sensor, sensing device, or sensor switch such as a heat sensitive switch, an infrared switch, a steam or gas sensor switch, or a magnetic proximity switch is provided, while an induction heating element is provided on the side to be heated, and the induction heating element is placed at least on the top of the induction heater side. In an induction heating appliance whose side close to the plate is covered with a heat insulating material with excellent heat insulation and heat resistance, a convex part or a concave part is provided so as to fit into a concave part or a convex part on the induction heater side. The convex part or the concave part is provided with a hole, or an infrared transmitting material is fixed in the hole, so that the convex part of the induction heating device is not heated when the induction heating body is heated or when heating is completed. Or, at least one of the media such as heat, infrared rays, steam, gas, magnetic force, etc. is released from the concave part, and the convex part or concave part of the induction heating appliance is connected to the concave part or convex part of the induction heater. Only when these are fitted together, the magnetic proximity switch on the induction heater side is activated by the proximity of the magnetic body of the induction heating element of the induction heating appliance, thereby energizing the induction heater side. In addition, when the induction heating device reaches a certain high temperature, the sensor or detector of the induction heating device is activated to turn off the power, weaken the current or voltage, or control the induction heating device. A safety device for an induction heater and an induction heating appliance comprising: (2) A smaller convex or concave portion is formed within the concave or convex portion on the induction heater side, and the sensor, sensing device, sensor switch, etc. is installed in the small convex or concave portion. On the other hand, the hole in the convex part or concave part of the induction heating device is formed so large and deep that the small convex part or concave part on the induction heater side can be inserted therein, and the small convex part or concave part can be inserted therein. By pushing out the on-off valve made of a material with excellent heat insulation and heat resistance that is loosely fitted in the middle of the hole, a gap is created between the hole and the on-off valve, and the induction heating is performed from the gap. A restoring mechanism is provided so that heat, infrared rays, steam, gas, magnetic force, etc. from the body can be released, and the gap is closed by removing the small convex or concave portion from the induction heating device. A safety device for an induction heater and an induction heating appliance according to claim 1, characterized in that the safety device is configured by being provided on the on-off valve. (3) Instead of a smaller convex or concave part in the concave or convex part of the induction heating appliance, the thermostat, thermistor heat-sensitive switch, infrared switch, steam or gas sensor switch, magnetic proximity switch, etc. The induction heater and induction according to claim 2 of the utility model registration claim, wherein a sensor or a sensor switch is provided protrudingly, and the insertion of the protruding sensor or sensor switch pushes out the on-off valve on the induction heating appliance side to create a gap. Safety device for heating appliances. (4) On the other side of the gap created by pushing out the on-off valve of the induction heating appliance, an infrared transmitting material is present between the gap and the induction heating body. A safety device for an induction heater and an appliance for an induction heater according to any one of paragraphs 1 and 3. 5) A thermoelastic body made of a shape memory alloy is used to heat a part or all of the induction heating device, one end of which is locked to the induction heating body and the other end of which is locked with a magnetic piece. At the start or during heating, those parts that are away from the top plate of the induction heater or that are not exposed through the holes of the induction heating device will receive heat from the induction heating element at the end of heating the induction heating element. By approaching the top plate of the induction heater by conduction or being exposed through a hole in the induction heating device, a magnetic proximity switch separately provided in a concave or convex portion of the surface of the top plate of the induction heater is actuated. By storing in advance the thermoelastic body so that it will deform when it reaches a certain temperature due to the temperature rise at the end of heating, the induction heater can be controlled to turn off the power or weaken the current or voltage. An induction heater and a safety device for an induction heating appliance according to any one of claims 1 to 3 of the utility model registration claims. (6) Provide a concave or convex portion on the surface of the top plate of the induction heater without any sensor, sensing device, sensor switch, etc., and correspond to the concave or convex portion on the induction heating appliance side. A convex part or a concave part is provided so that it can fit into a concave part or a convex part of the induction heater in a shape such that it can fit into a concave part or a convex part of the induction heater. All of the concave and convex parts of the appliance are constructed so that they can fit into each other, and when no heating is being performed, the induction heating element of the induction heating appliance is detached from the top plate of the induction heater at exactly any point, and the induction heater is Induction heating according to any one of claims 1 to 5 of claims 1 to 5, which is configured to turn off the power or weaken the power or voltage without activating a magnetic access switch or the like on the side. Safety equipment for induction heating equipment.
