Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an improvement in an electric heating pot for heating and keeping a contained liquid warm.

Conventional configurations and their problems In the past, various electric heating pots have been devised.This configuration has a lid on top, and has a double structure consisting of a bottomed container with an open top and an exterior body. A band-shaped heating element was wrapped around the lower outer periphery of the container, and a humidity controller was installed at the bottom of the container and outside the middle of the container. In order to increase the heat insulation effect, that is, the heat retention effect, wrap the outer circumference of the container with various flexible heat insulating materials such as glass resin #, ceramic #usa, etc., or wrap and install a metal reflective plate in the same way. was.

In these cases, the above-mentioned temperature controller should be installed near the middle of the container body at a certain distance from the band-shaped heating element to minimize the influence of heat radiation from the heating element. They were trying to correlate it with the imperial treasures. However, if the generator is in this position depending on the altitude, the thermal influence from the heating element will be significantly different depending on whether it is above the liquid water level or temperature controller or in the Royal Palace1], and the temperature correlation Due to the difference in gender, it was necessary to pay attention to the minimum water level during the first renewal.

Furthermore, since the controller is located in the middle of the body of the container, the electrical wiring is concentrated at the bottom of the container, which increases the length of the electrical leads from the controller, which increases the cost accordingly. In addition, since the container is cylindrical, in order to attach the controller, the container must be locally processed to improve the adhesion with the controller and to improve the correlation with the heated liquid. It was not desirable because it had a strange shape.

In addition, a notch is required in the part facing the controller for heat retention, and since a pan-shaped heating element is wrapped around the lower outer periphery of the container, there is no need for a cutout on the top of the container.

It did not cover the entire lower area, which caused a loss in heat retention efficiency. As a means of supplementing this heat retention efficiency, thermal insulation and metal reflectors were installed in layers, but this caused problems with assembly and cross-linking.

OBJECTS OF THE INVENTION The purpose of the present invention is to eliminate or improve the conventional drawbacks mentioned above, and to provide an electric heating pot that has excellent correlation between heating liquid and temperature controller, heat retention, and productivity. It is.

Structure of the Invention In the present invention, a heating element, a temperature controller, and a temperature-sensitive reed switch are attached to the bottom of the inner container, so that an electric image height bot with good heating efficiency can be obtained.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the drawings, 1 (-1) is a heat exchanger plate with an outer peripheral side edge that protrudes to one side, and the outer edge is attached to the lower end of the cylinder by means such as welding in a liquid-tight manner, A metal container 2 is formed. Reference numeral 3 denotes an exterior body that encloses the container 2 through a space, and between the outer body 3 and the container 2, a protective cover 4 is placed around the entire outer periphery of the container 2. They are placed close together.

A heating element is inserted below the heat transfer plate 1 (in which the main heating part and the auxiliary heating part are wrapped together with heating wires, and the heating plate 5 is laminated with insulating plates 6 and 7 on the top and bottom, The central part of this heating element has a through-hole part.This heating plate 5 (d) has a through-hole in the central part, a metal diffusion plate 8 with good thermal conductivity having an outer circumferential side part, and a rear side part 9. They are held together in a thousand pieces to form the entire heating element section.

Note that the heat diffusion plate 8 and the backing material 9 described above have their outer circumferences ff.
At part f11, cutouts 24 and 25 of a continuous light size are provided.

Below the heating element part, a metal heat shield plate 10 has its outer peripheral edge connected to the lower outer peripheral part of the container 2 in a substantially intimate state.

The heat shield plate 10[ is the aforementioned heat diffusion plate 8. Square holes are provided corresponding to the notches 24 and 25 in the 9° backing material, and a through hole is provided in the center of the heat shield plate 10 (the area around this hole is located in the center of the heating element). A heat shield part 11 made of a single-cave foundation having a hollow hole 11a is brought close to this through hole with an appropriate space.At the bottom of the hollow part of the heat transfer plate 1, Temperature control!L!?i12 is inside the hollow hole 11a of the heat shield part 11 (・ζ number phrase member 13. Pressing spring 1

On the upper part of the container 2 (through the d1 backing 18, a cover part 19 and a lid part 2o are placed, a wj handle 21 is fixed to the side of the exterior body 3, and a At the same time, the metal fittings 22 are fixed and the back plate 23 is connected, and the above-mentioned main heat generating section (humidity controller 12 and auxiliary heat generating section + sensitive reed switch 16) is directly connected to the electric circuit to form a parallel circuit. An electric heating pot has been completed.

In the above-mentioned configuration, when the container 2 (2) contains a liquid and electricity is started, the heating plate 5 is heated, and the heat is transmitted to the liquid through the heat transfer plate 1, and at the same time, the outer periphery (!+
Heat is also transferred in the direction of the part 1), and the heat transferred to the back shrine 9 is transferred to the outer circumferential side and is used to heat the liquid.When the liquid reaches a certain temperature, the heat is transferred to the back shrine 9. The central protrusion of (
The temperature controller 12 connected to the main heating element is activated, the main heating element is turned off, and only the low-power auxiliary heating element is energized. When the liquid reaches a certain temperature (on The sensitive slip-1' switch 16, which is set to operate, is actuated and turned on, reversing the downhill cycle and ensuring a low power thermal insulation state.

Since the heat dissipation of the heat generating plate 5 is carried out smoothly in this way (it is possible to reduce the temperature of the entire IC1 heat generating plate and extend its durability life), Radiation and 7J of temperature controller 12-\ from heating element part
Combined with the effect of blocking flowing heat, +1 Temperature Control 1 device 12 Significantly lowers the atmosphere in the vicinity, liquid temperature and temperature controller 1
The correlation between the working hot water temperature of 2 is set to be high.

The temperature-sensitive reed switch 16 has cutouts 24 and 26 and a square hole in the aforementioned components, so it cuts off the influence of heat from the heating element and prevents the operating temperature correlation and heat loss with the liquid 21. Keeps liquid warm with extremely high precision7. We guarantee m degrees.

In addition, even if the furnace is initially empty due to misuse, or if the remaining water is empty, the heat exchanger plate 1. Heat diffusion plate 8. It's tj4 and it's 11? 1ill previous 11 domains 12. Heat can be immediately transferred to the demand reed switch 16, ensuring safety.
Furthermore, the heat insulating material 4 can be attached to the entire area above and below the container 2, and the lower part can be extended by folding the back plate 23, increasing the heat retention effect! It is a sign. Further container 2
Since there is no temperature controller 12 or attachment parts in the space of the exterior body 3 and the space is only the thickness of the heat insulation side 4, if the exterior body 3 is made smaller by that amount, it becomes possible to The lead wires are gathered at the bottom of the container 2 to facilitate assembly. In addition, heat is transferred directly to the liquid from the heat transfer plate 1, thereby improving heating efficiency.

When the heat shield plate 10 is made of metal and the outer circumferential member is brought into close contact with the lower outer circumference of the container 2, when liquid is placed in the container 2 and heated with electricity, the heat shield plate 10 (a) starts to increase the temperature of the hot water; At this time, the temperature of the liquid is low, and the temperature below the customer device 2 is also low, which serves to prevent the blackness of the heat shield plate 10 which is in a substantially dense M state from increasing, and the likelihood controller 12 is adjusted accordingly. It is possible to prevent the atmospheric salinity from rising, to further consider the relationship between the liquid temperature and the temperature controller, and to correct the high blueness.

Effects of the Invention As described above, according to the present invention, since there is a high temperature correlation with the liquid, it is possible to provide an electric heat-retaining bot that has high heating efficiency, is safe, and is low in cost.
