Description

[Detailed Description of the Invention] The present invention relates to an electric heating pot that heats water contained in a container using a heating element.

Generally, in this type of conventional electric heating pot, a heating element is attached to the outer surface of the bottom of the container, and the heating element heats the water contained in the container.

By the way, the above-mentioned heating body is formed by embedding a sheathed heater in a heat transfer plate cast in a shape corresponding to the bottom of the container, and the heat transfer plate is joined to the outer surface of the bottom of the container.

However, since the accommodating body and the heat exchanger plate are simply joined together, these two do not adhere well.

As a result, the heat from the heating body is not transferred well to the housing body, causing the heating body itself to heat up, and the amount of heat dissipated from the heating body to the outside air to increase, resulting in efficient heating of the water inside the housing body. The problem was that I couldn't do it.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to transfer heat from a heating element attached to the outer surface of the container to the water contained in the container through a heat pipe. To provide an electric heating pot capable of efficiently heating water.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is a bottomed cylindrical case with an open top.

An inner lid 2 having a large opening 2a is attached to the upper end of the case 1.

A stopper 3 is removably fitted into the opening 2a of the lid 2 through a backing 4 in an airtight manner.

A water supply port 6 is formed in the center of the stopper 3, into which an inner stopper 5 is removably fitted in an airtight manner.

The inner stopper 5 is provided with a lower conduit 7 on its lower end surface,
On the side, one end is connected to the lower conduit 7 and the other end is connected to the inner lid 2.
An upper conduit 9 is provided facing a pouring spout 8 formed in the upper part.

Further, an outer cover 10 having a built-in pump mechanism such as a bellows (not shown) is connected to the inner cover 2 so as to be openable and closable.

This outer cover 10 is provided with a pusher 11, and this pusher 1
By pressing 1, the pump mechanism is activated, and compressed air is discharged from a discharge portion 12 formed on the lower surface of the outer lid 10.

In addition, the discharge part 12 is adapted to come into close contact with the inner stopper 5 when the outer cover 10 is joined to the inner cover 2.

The compressed air discharged from the discharge part 12 is ejected into the container 13 (described later) through the inner stopper 5, pressurizes the water contained in the container 13, and sends this water through the lower conduit 7. It is designed to be discharged from the upper conduit 8 through the pipe.

On the other hand, the container 13 is formed of a metal material into a cylindrical shape with a bottom, and a flange 14 is formed on one end thereof so as to face outward.

This container 13 has its flange 14 connected to the inner lid 2.
After the backing 16 is airtightly fitted into the mounting groove 15 formed on the lower surface of the inner lid 2, a ring-shaped presser body 17 having a cross-sectional shape is inserted into the lower surface of the inner lid 2 with the screws 18...・
・It is held in the case 1 by fixing it with.

Note that the space between the case 1 and the container 13 is filled with a heat insulating material (not shown) such as glass wool.

Further, on the bottom surface of the housing body 13, a heating body 21 consisting of a plate-shaped heat transfer part 19 formed by casting aluminum, for example, and a sheathed heater 20 embedded in this heat transfer part 19 is installed. A heating section 19 is attached to the bottom surface of the container 13.

A cylindrical support part 22 is provided at the center of the heat transfer part 19 of the heating body 21, and the housing 1 corresponds to this support part 22.
An insertion hole 23 is bored in the bottom surface of 3.

A heat pipe 24 is airtightly held and fixed to the support portion 22.

That is, the heat pipe 24 is provided with a protruding collar 25 at its midpoint, a threaded portion 26 formed at one end, and a backing 27 interposed between the collar 25 and the bottom surface of the container 13. The threaded portion 26 is inserted into the insertion hole 23 of the container 13.
It is fixed by fitting it into the support part 22 and screwing a coupling body 27a such as a nut onto the screw part 26 protruding from the support part 22.

Therefore, the heat pipe 24 has one end connected to the heating element 2.
1, and the other end protrudes into the container 13.

Furthermore, a connecting portion 28 is provided at the bottom of the case 1 to be connected to a power source and to supply electricity to the heating body 21 .

Note that the power supply to the heating body 21 is controlled by a temperature detector (not shown) that detects the temperature of the housing body 13, so that the temperature of the water contained in the housing body 13 is kept constant. ing.

According to the above configuration, when the heating body 21 is energized, the heat transfer part 19 is heated by the sheathed heater 20, so that heat is transferred from the heat transfer part 19 to the container 13, and the inside of the container 13 is heated. The ice will be heated.

By the way, when the heat transfer part 19 of the heating body 21 is heated, the heat pipe 2 supported by the support part 22 of this heat transfer part 19
Since one end of 4 is also heated, this heat pipe 24 is
Heat is radiated from the other end protruding into the housing 13.

Therefore, the heat of the heating body 21 is transferred to the water in the container 13 by the heat transfer section 19 and the heat pipe 24, so that heat loss such as heat dissipation of the heating body 21 into the atmosphere is prevented. The water inside the container 13 is efficiently heated.

Further, a flange 25 is formed on the heat pipe 24, and this flange 25
Since the bottom of the container 13 is held between the heat transfer portion 19 of the heating body 21 and the bottom of the container 13, the degree of close contact between the bottom of the container 13 and the heat transfer portion 19 is increased, and heat transfer from the heat transfer portion 19 to the container 13 is increased. is carried out efficiently.

As described above, in the present invention, a heat pipe is provided by attaching one end to the heating body attached to the outer surface of the container containing water and protruding the other end into the container, so that the water inside the container is It is heated by a heating element and a heat pipe.

Therefore, even if the degree of adhesion between the heating element and the housing is poor,
Since the heat of the heating element can be directly transferred to the water inside the container using a heat pipe, there is less waste such as the heat dissipated into the atmosphere as in the past, and heating efficiency is improved. It has a great effect.

In addition, a collar is provided in the middle of the heat pipe, and the wall of the housing is compressed between the collar and the heating body, which increases the degree of close contact between the housing and the heating body, and improves the efficiency of heat transfer to the housing. It has the advantage of being able to measure improvements.
