Claims (1)

[Claims for Utility Model Registration] (1) A water injection container with a siphon device housed in the pot body, and an opening/closing device that is attached to the upper opening of the pot body and is provided with a pump for driving the siphon device. The water injection container has a lid and an electric heating circuit that heats the water injection container, and the water injection container is provided with a discharge path for discharging internal boiling steam to the outside separately from the siphon device, and the electric heating circuit is arranged inside the water injection container. The water in the water injection container is configured to be able to switch between a boiling heating state and a heat retention state in which the water in the water injection container is maintained at a predetermined temperature, and this switching is performed by a ferrite thermal sensor provided in the discharge path, The ferrite thermal sensor includes a temperature-sensitive ferrite that detects boiling steam flowing through the exhaust path and has a characteristic of reaching the Curie point at the time of detection, and a movable magnet that attracts the temperature-sensitive ferrite and connects an actuating piece.
A spring that urges the movable magnet in a direction opposite to the attraction direction with a force smaller than the magnetic attraction force when the magnet is attracted to the temperature-sensitive ferrite, and a direction in which the movable magnet moves away from the temperature-sensitive ferrite due to the spring. When the movable magnet is attracted to the temperature-sensitive ferrite, it cooperates with the operation of the actuating piece to keep the electric heating circuit in a warm state. On the other hand, when the movable magnet is attracted to the temperature-sensitive ferrite, it cooperates with the operation of the actuating piece to keep the electric heating circuit warm. a switch means for switching the circuit to a boiling heating state, and a reset button is provided on the operating piece of the ferrite thermal sensor to move the movable magnet to the temperature-sensitive ferrite side against the spring; The reset button is arranged on the outer surface of the opening/closing lid, and the position of the reset button changes when the movable magnet attracts and separates from the temperature-sensitive ferrite. (2) The switching means is constituted by a contact that is normally closed by an elastic contact piece, and the actuating piece, when moved by the spring, moves the elastic contact piece against its elasticity. A jar pot according to claim 1, which is configured to be deformed so that when the movable magnet is separated from the temperature-sensitive ferrite, the normally closed contact is opened and the electric heating circuit is switched. . (3) The above-mentioned reset button is provided at the terminal of the above-mentioned actuating piece, and the above-mentioned reset button is configured to protrude from the opening/closing lid when the movable magnet is separated from the temperature-sensitive ferrite. Jar pot as described.
