BACKGROUND ART A large number of electric heating pots that have both the functions of boiling water and keeping warm water have been provided on the market. The main points of its composition are:
A lid is placed on the top, and a bottomed container with an opening at the top and an exterior body form a double structure.A band-shaped heating element is wrapped around the lower outer circumference of the bottomed container, and A temperature switch was installed on the outside of the section.

巻装したシしていた。In addition, in order to enhance the heat insulation effect, that is, the heat retention effect, various flexible heat insulating materials, such as glass fibers and ceramic fibers, were wrapped around the outer periphery of the container, or a metal reflective plate was similarly wrapped around the container.
前述のように、液体の加熱は、容器を発熱体で加熱し、
加熱された容器の熱を液体に供給するいわゆる間接加熱
法であった。As mentioned above, heating the liquid is done by heating the container with a heating element,
This was a so-called indirect heating method in which heat from a heated container was supplied to the liquid.

大きくなり、コスト高になっていた。Problems to be Solved by the Invention With such a conventional structure, the heat insulating material is a flexible heat insulating material made of fibers, so when wrapping it around a container, it is difficult to connect it with strings, loose bands, etc. This was the norm, resulting in extremely poor workability and hindering productivity. In addition, it is common to install a band-shaped heating element on the lower outer periphery of the container, and the above-mentioned heat insulating material is often placed above the heating element and wrapped around the outer periphery of the container. Since it was not placed on the entire surface of the container, there was a loss in heat retention efficiency. In addition, the temperature controller was installed at a certain distance from the heating element and at an intermediate position on the body side of the container, in order to establish a correlation between the heated liquid and the temperature controller. However, when the temperature controller is in this position, the temperature correlation will be significantly different depending on whether the liquid level is above or below the temperature controller, and it is necessary to pay attention to the minimum water volume from the standpoint of use. Ta. Furthermore, it was necessary to remove a notch in the heat insulating material at the temperature controller, which had a corresponding effect on the heat insulating effect. Therefore, as a means of compensating for the decrease in the heat retaining effect, a metal heat shield plate has been installed over the entire outer periphery of the heat retaining material, but this inevitably results in an increase in cost. Furthermore, although electrical wiring can generally be simplified by concentrating it on the bottom of the container, it is difficult to install the band-shaped heating element in the lower body of the container and the temperature controller Since the installation position is midway between the sides of the body, the electrical lead wires are long and assembly is complicated, leading to increased costs. In addition, since it is a band-shaped heating element, the process of heating the liquid as described above involves first heating the container, and then transmitting the heat of the heated container to the liquid.
In other words, the liquid was heated through the container. As a result, it cannot be said that the heating efficiency is good, and in order to suppress the temperature rise of the heating wire that is the heating element and guarantee the durable life of the heating element, the power density (W/d) of the heating element is determined based on empirical values. As a result, the absolute surface area of the heating element becomes large, leading to high costs.

部に向けて１頃次肉厚となるようにし、伝熱部材の中方
下方に前記温度制御器を配設したものである。Means for Solving the Problem In order to solve this problem, the present invention provides a vacuum space between the double-structured inner and outer bodies, and a heating element and a temperature controller are provided at the bottom of the container of the inner body. In order to achieve the intended purpose, this heating element is connected to a heating panel, a heat diffusion member with good thermal conductivity installed closely on the bottom surface of the heating panel, and a heat diffusion member that covers the bottom surface of the heat diffusion member. a back member, and the peripheral edges of the heat transfer member, the heat diffusion member, and the back member are brought into close contact with each other,
A through hole is formed in the center of each of the heating plate, the heat diffusion member, and the back member, and the heat diffusion member is made to have a thickness of about 100 mm from the inner circumference toward the outer circumference. The temperature controller is placed below.

向へ積極的に熱拡散される。背面材へ伝達された熱は外
周側部へ伝わりこれも液体の加熱に供される。Effect With this configuration, when liquid is stored in the container and electricity is started, the heating plate is heated, heat is transferred directly to the liquid through the heat transfer part, and at the same time, heat is diffused toward the outer circumferential side through the heat diffusion member. The liquid is heated through the side edges of the heating element. Furthermore, since the heat diffusion member is gradually thickened toward the outer circumference (from the circumferential portion), the heat diffusion described above is actively diffused toward the outer circumference. The heat transferred to the backing material is transferred to the outer peripheral side, which also heats the liquid.
発熱体の発熱エレメントは熱拡散部材の熱拡散のため線
温度を著しく低下させ、耐久力伸長を保証する。The heating element of the heating element significantly reduces the wire temperature due to the heat dissipation of the heat dissipating member, ensuring increased durability.

ているものである。When the liquid reaches a certain temperature, the temperature controller is activated and the liquid moves to the heat retention stage, but the above-mentioned effect between the vacuum walls maintains high heat retention. Furthermore, the effect of the heat diffusion member and the effect of the heat shield plate are combined to lower the temperature near the temperature controller, thereby making the correlation between the liquid temperature and the operating temperature of the temperature controller highly accurate.

段階へと移行する。In the above configuration, when a liquid is stored in the container 2 and electricity is started, the heating plate 51L is heated, heat is directly transmitted through the heat transfer member 1, and at the same time, the heat is diffused toward the outer peripheral side through the heat diffusion member 8. . The diffused heat is used to heat the liquid through the side edge 1a of the heat transfer member 1. Back member 12
The heat transferred to the peripheral edge 9 is transmitted to the periphery 9 and is used to heat the liquid. When the liquid reaches a certain temperature, the temperature controller 14 disposed below the central protrusion 1b of the heat transfer member 1 is activated, and the process moves to the heat retention stage.

るものである。In this way, since the heat dissipation of the heat generating plate 6a is performed smoothly, the linear temperature of the heat generating element 5 is significantly lowered.
Even if the heat generating element 5 is set so that the linear temperature increases as it goes toward the outer periphery (the amount of heat generated increases as it goes toward the outer periphery of the tab), the thickness of the heat dissipating member 8 in the outer periphery direction increases accordingly. Therefore, the increase in the wire temperature is increased in the amount of heat diffusion downward and to the sides, and is transmitted to the side edge 1a of the heat transfer member 1, thereby reducing the wire temperature and extending the durability life.

2 and heat diffusion member 8. Since both sides are sandwiched by the heat transfer member 1, this is prevented. Furthermore, if the durability is set to the same level as before, due to the aforementioned good conductivity and good heat diffusion,
It is possible to set the power density CW/ci to a high density, and the size of the heating element can be made compact. In addition, the effect of lowering the temperature of the heating element part and the effect of the metal heat shield plate 13 are combined to lower the ambient temperature near the temperature controller 14, and the correlation between the liquid temperature and the operating temperature of the temperature controller 14 can be established with high precision. is doing. In addition, even in the case of dry baking with residual water due to misuse or dry baking from the initial state, the central convex part of the heat transfer plate 1 and the heat diffusion member 8 work to immediately transfer heat to the temperature controller 14 to ensure safety. This is guaranteed.
一定温度に達した液体は、外装体３と容器２との壁間が
真空状態になっているため、保温効果が優れ、極めて緩
慢な保温状態に移行するものである。When the liquid reaches a certain temperature, since there is a vacuum between the walls of the exterior body 3 and the container 2, the heat retention effect is excellent, and the temperature transition is extremely slow.

It is possible to converge at the bottom, reducing assembly man-hours and improving heat retention performance. Moreover, instead of indirect heating using the conventional band-shaped heating element, the heat of the heating plate 5 is directly transferred to the liquid from the heat transfer plate 1, thereby achieving good heating efficiency.
