[0004]

[Problems to be solved by the device]

 However, in such a conventional electric hot water outlet pot, if the power cord plug is removed from the plug receiver, the electric pump cannot be operated, and therefore the power cord plug must always be connected to the plug receiver. As a result, the position where the pot is placed is restricted by the power cord, and there is an inconvenience that it is impossible to carry the pot to an arbitrary position for use after boiling.

The present invention has been made in view of such a point, and an object thereof is to allow an electric pump to operate and optionally discharge hot water even if a plug of a power cord is removed from a plug receiver. It is to provide a convenient electric hot water outlet pot.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides a container in a pot body, a main heater and a sub-heater in the container, a pot receiver in the pot body, and a plug for a power cord attached to the plug receiver. The main heater and the sub-heater heat the water in the container to boil, and after the boiling, the main heater is de-energized via the heat responsive element to keep the water in the container warm by the sub-heater. In the case where hot water in this container is poured out by the operation of an electric pump, it has a charging battery, and the charging circuit in which this charging battery is conducted to the plug receiver is connected in series with the electric pump and the hot water switch. However, in conjunction with the drive circuit that connects these electric pump and hot water switch to the charging battery and the operation of the thermal response element, this thermal response When the child is turned on, the charging circuit is closed and the drive circuit is opened.When the thermoresponsive element is turned off, the charging circuit is opened and the drive circuit is closed. is there.

[0007]

[Action]

 When using the pot, store water in the container and connect the plug of the power cord plugged into the indoor outlet to the plug receiver of the pot body. In response to this, the main heater and the sub heater are respectively energized, and the water in the container is heated by the main heater and the sub heater. Then, the thermal response element keeps the ON state, by which the charging circuit is closed via the contact switching mechanism, the driving circuit is kept open, and the charging battery is gradually charged by closing the charging circuit. It

The temperature of the water in the container gradually rises due to the heating by the main heater and the sub heater, and after a certain period of time, it becomes hot water and boils. In response to this boiling, the heat response element is turned off, and accordingly, the main heater is de-energized, and the hot water in the container is kept warm by the sub heater as hot water.

The contact switching mechanism operates in response to the turning off of the heat responsive element to open the charging circuit and close the driving circuit. Therefore, when the hot water switch is closed in this state, the electric pump is energized using the already charged charging battery as a power source, and the electric pump operates. Then, the hot water in the container is poured out by the operation of the electric pump.

While the water in the container is being heated by the main heater and the sub-heater, that is, while boiling or boiling water, the contact switching mechanism keeps the drive circuit in an open state. Even if the hot water switch is operated under the hot water, the electric pump does not operate, and the danger that the low temperature hot water in the container is poured out or the boiling hot water is poured out and scattered is avoided.

When the plug of the power cord is removed from the plug receiver of the pot body after completion of boiling water, the state in which the drive circuit is closed is maintained as it is, and therefore the charging battery is powered by operating the hot water switch. As a result, the electric pump is energized, and the hot water in the container can be poured out by the operation of this electric pump.
