Abstract

PROBLEM TO BE SOLVED: To circulate-heat an appropriate amount of water in a subtank and heat the water to an appropriate temperature by turning on power on a spiral pipe heater which is attached to the side surface of the subtank, for a main body which is divided into a main tank and the subtank. SOLUTION: In a spiral pipe heater 4 having an electrode 3, which is attached to the side surface of a subtank 13 of a main body 13 being divided into a main tank 1 and the subtank 2, a temperature switch 11, an electromagnetic switching type 3-way valve 16 and a pump 6 for hot water are provided. That is, by providing the subtank 2, a required amount of hot water only is boiled, and the necessity of a heat insulation which occupies 80% or higher of the required electric energy can be eliminated, and the electric energy can be kept at 20% or lower.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household electric kettle.

[0002]

2. Description of the Related Art A conventional electric water heater uses indirect heating, and has a drawback that it is difficult to rapidly heat an appropriate amount for one use.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to directly supply electricity to the spiral pipe heater 4 to boil water, and it is an object of the present invention to provide a power-saving pot that can boil water quickly with high efficiency.

[0004]

Means for Solving the Problems In order to solve the above-mentioned object, current is directly supplied to the electrodes 3 at both ends of the spiral pipe heater 4 attached to the sub-tank 2 and the power is turned on / off by a temperature switch 11 and the electromagnetic switching type three way. A means for switching the valve 16 is provided.

[0005]

According to the present invention, since the above-mentioned means are taken, the temperature switch 11, the electromagnetic switching type three-way valve 16 and the hot water pump 6 are supplied from the electrodes 3 at both ends of the spiral pipe heater 4 in use.
And connect a power supply so that the spiral pipe heater 4 can be energized.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a first embodiment, in which a temperature switch 11 and an electromagnetic switching type three-way valve 16 are connected to electrodes 3 at both ends of a spiral pipe heater 4 and a power source is connected. Then, an appropriate amount of water is injected from the main tank 1 into the sub-tank 2 by the sub-tank supply pump 7, and the electromagnetic switching type 3
While the water sucked from the heater inlet by the switching of the direction valve 16 and the hot water pump 6 is heated while passing through the inside of the spiral pipe heater 4 energized and heated by the power supply operation by the temperature switch 11, the hot water pump from the heater outlet 15 is heated. 6
Through the electromagnetic switching three-way valve 16 to the inside of the sub-tank 2 and circulates until the temperature reaches an appropriate temperature.
The hot water is supplied from the hot water outlet 5 by switching the direction valve 16.

The spiral pipe heater 4 is preferably made of stainless steel which does not rust.

It is desirable that the temperature switch 11 can switch the temperature freely.

The sub-tank supply pump 7 is desirably one that can freely change and set the amount of water supplied.

[0011]

As described above, according to the present invention, only the necessary amount of hot water is boiled by the provision of the sub-tank 2, so that the necessity of keeping the heat occupying 80% or more of the required electric power is eliminated. % Or less.
