Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric kettle for boiling water and keeping it warm.

[Conventional technology]

Conventionally, electric pots have a wide-mouthed inner bottle surrounded by an outer case, a bottomed cylindrical tank is installed inside the wide-mouthed inner bottle, and a heat source and temperature controller are installed in the space between the inner bottle and the tank. The shoulder member is connected to the upper end of the outer case, the bottom member is connected to the lower end of the outer case, the upper end of the tank is connected to the lower end of the shoulder member, a plug holder is provided at the rear of the lower end of the outer case, and a heat source and a temperature controller are connected. The terminal of the lead wire passes between the inner bottle and the tank, rises, passes through the lower end of the shoulder member, descends between the inner bottle and the outer case, and connects to the plug receiver, and connects the inside of the tank to the front of the shoulder member. Although a connected beak was provided for dispensing liquid, it was extremely difficult to attach lead wires to this type of electric pot, and when dispensing liquid, the liquid was disconnected after disconnecting the power cord connected to the plug receptacle. Because the pot had to be tilted to pour out the liquid in the tank from the beak of the shoulder member, it was heavy and did not fit smoothly into containers such as pots when tilted, making it difficult to use an electric pot. There was also a risk of getting the place where it was placed wet or getting burned by boiling water splashing out.
