A hot plate is stretched over the top of the pedestal body, and a removable container is placed on the hot plate of the pedestal body. The liquid in the container is heated on the bottom peripheral wall of the hot plate through the hot plate. There was a heater to do this.

A first control sensor that penetrates through the center of the hot plate to come into contact with the bottom wall of the container and indirectly senses the temperature of the liquid in the container; A temperature controller is provided which includes a second control sensor which extends toward the base and operates by detecting the ambient temperature in the container. The temperature controller is connected in series with the heater, and a plug receiver is provided at the rear end of the pedestal body. When a plug is inserted into this plug receiver and an external power source is supplied, the heater and the temperature controller are energized to heat the hot plate and heat the liquid in the container.

[0004]

Since the conventional kettle is constructed as described above, even if the container is not placed on the pedestal body, power is supplied to the plug receiver and the temperature controller at the same time. Since the heater is energized, both the first control sensor and the second control sensor of the temperature controller always detect the outside air temperature, and the heater is always 0N.
It was supposed to maintain the state of and use a very useless power consumption.

Further, even after removing the container from the pedestal body into which the plug is inserted, the hot plate of the pedestal body continues to be heated, so unless the container is removed and the plug is not removed at the same time, the hot plate is accidentally touched. There was a risk of doing so, and the operability was very troublesome.

The present invention has been made in order to solve the above problems, and an object thereof is to obtain an electric kettle capable of efficiently supplying electric power and having high safety and operability. To do.

[0007]

The boiling pot according to the present invention is such that the first control sensor and the second control sensor of the temperature controller are energized only when the container is set in the pedestal body.

[0008]

In the boiling water pot according to the present invention, when the container is set on the pedestal body, the temperature controller for turning the heater to 0N and 0FF is energized. Since it is not heated, the power supply is very efficient. Also, in the pedestal body with the container removed, the hot plate does not become hot just by inserting the plug receiver, so it is extremely safe and it is not necessary to attach and detach the plug with the attachment and detachment of the container as in the past, and operability is easy.
