It's coming. The main point of its construction is that it has a double structure consisting of a bottomed container with a lid placed on top and an exterior body with an open top, and a band-shaped heating element wrapped around the bottom outer circumference of the bottomed container. Temperature controllers were installed at the bottom and outside of the middle of the container.

ていた。Problems to be Solved by the Invention In this conventional configuration, 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 a string or a suitable band. This was common practice, and was extremely inefficient and hindered 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 they are not provided over the entire upper and lower outer peripheral surfaces of the container, there is a loss in heat retention efficiency. Furthermore, the temperature controller is installed at a certain distance from the heating element and at an intermediate position on the body side of the container, thereby achieving a correlation between the heated liquid and the temperature controller. However, if 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 causes an increase in costs. 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 in the middle of the side 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, that is, indirect heating via the container. . As a result, the heating efficiency was not 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/cm 2 ) of the heating element must be set to an empirical value. As a result, the absolute surface area of the heating element becomes large, resulting in high cost.

したものである。Means for Solving the Problem In order to solve this problem, the present invention creates a vacuum space between the inner and outer bodies of the double structure, and provides a heating element and a temperature controller 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 becomes thicker from the inner circumference toward the outer circumference, and the thickness of the heat diffusion member is gradually increased from the inner circumference toward the outer circumference, and the thickness of the heat diffusion member is increased from the inner circumference to the outer circumference. The above-mentioned temperature controller is provided.

The liquid is heated through the side edges of the heat transfer member. Furthermore, since the heat diffusion member is gradually thicker from the circumferential portion toward the outer circumference, the aforementioned heat diffusion 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

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. moreover,
The effect of the heat diffusion member and the effect of the heat shield plate combine 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.

A heating element 5 made of iron, chrome, stainless steel, aluminum, etc. is formed into a desired shape by press working, etching, etc., and is layered with ring-shaped insulating plates 6 and 7 on the top and bottom to form a heating plate 5a. is formed. 8 is a thermally conductive heat diffusion member (for example, aluminum, aluminum alloy, copper, etc.) having a through hole 8a in the center and an outer peripheral side part 8b, and the thickness is gradually increased from the inner peripheral part to the outer peripheral part. This is closely attached to the lower side of the heat generating plate 5a. A back member 12 located below the heat diffusion member 8 and having a peripheral edge 9 on the outer periphery and an upward protrusion 11 having a through hole 10 in the center is a heat transfer member that covers the upper surface of the heat generating plate 5a. 1, side edge 1a, peripheral edge 9 and central protrusion 1

ａを接合する構成としてもよい。 The heat generating element 5 is electrically shaped so that the temperature is higher in the outer circumferential direction than in the center when electricity is applied. A metal heat shield plate 13 is provided below the heating element 5b, and a temperature controller 14 is attached to the lower center of the heat transfer member 1 by a mounting spring 15.
A spout 17 and a reservoir 18 are placed on the top of the container 2 and the exterior body 3 via a packing 16.
A handle 19 is fixed to the side of the exterior body 3, a mounting bracket 20 is fixed to the bottom of the container 2, and a hakama part 21 is provided below to complete the electric heat-retaining pot. Note that the body of the container 2 and the exterior body 3 are integrated, and the heating element 5 is attached to this.
It is also possible to have a structure in which a is joined.
ところで前記伝熱部材１、背面部材１２として

0.5〜２％モリブデン含有のフエライト系ステン
レス板を使用すると接合が極めて容易となる。 By the way, the heat transfer member 1 and the back member 12 are made of 18-8 stainless steel plate, 13-18% chrome,
If a ferritic stainless steel plate containing 0.5 to 2% molybdenum is used, joining becomes extremely easy.

保温段階へと移行する。 In the above configuration, when a liquid is stored in the container 2 and electricity is started, the heating plate 5a 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. The heat transferred to the back member 12 is transferred to the peripheral edge 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.
Move to the heat retention stage.

縁１ａに伝達し線温度低下を図り、耐久寿命を伸
長させるものである。 In this way, since the heat dissipation of the heat generating plate 5a is performed smoothly, the line temperature of the heat generating element 5 is significantly lowered, and the line temperature becomes higher as the heat generating element 5 moves toward the outer periphery. Even if it is set so that the amount of heat generated increases as the direction increases, the thickness of the outer periphery of the heat diffusion member 8 is increased accordingly, so that the amount of heat diffusion is reduced downward and to the sides by the linear temperature rise. This increases the amount of heat transferred to the side edge 1a of the heat transfer member 1, lowers the wire temperature, and extends the durability life.

よび熱拡散部材８の働きにより、温度制御器１４
へ直ちに熱を伝え安全を保証するものである。 The heat deformation and warpage of the insulating plates 6 and 7 due to the high temperature of the heat generating element 5 are caused by the heat generating plate 5.
This is prevented because both sides of a are held between the back member 12, the heat diffusion member 8, and the heat transfer member 1.
Furthermore, if the durability is set to the same level as before,
Due to the aforementioned good conductivity and good heat dissipation, it is possible to set the power density [W/cm 2 ] to a high density,
This allows the size of the heating element to 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 increase the temperature controller 14.
The ambient temperature in the vicinity is lowered, and the correlation between the liquid temperature and the operating temperature of the temperature controller 14 is made highly accurate.
In addition, even in the case of dry-firing with residual water due to misuse or dry-firing from the initial state, the temperature controller 14
It immediately transfers heat to the body and guarantees safety.
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つているため、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, the space between the walls of the exterior body 3 and the container 2 is in a vacuum state, so the heat retention effect is excellent and the temperature transition is extremely slow.
さらに、容器２内の熱液体のため、外装体３お

のである。 Furthermore, due to the hot liquid inside the container 2, gas is generated from the exterior body 3 and the container 2, and the degree of vacuum between the vacuum walls decreases, and the heat retention effect deteriorates. 4 adsorbs generated gas, prevents the degree of vacuum from decreasing, and guarantees the heat retention effect.

発熱盤５の熱を伝熱板１より直接液体に伝えるも
のであり、良加熱効率を得るものである。 Furthermore, since the heating element section and the temperature controller 14 are concentrated at the bottom of the container, it is possible to extend the space between the vacuum walls as far as possible to the bottom of the container, and at the same time, it is possible to easily connect electrical wiring leads to the container. It is possible to converge at the bottom, reducing assembly man-hours and improving heat retention performance. Moreover, instead of the indirect heating of the conventional band-shaped heating element,
The heat of the heat generating plate 5 is directly transferred to the liquid from the heat transfer plate 1, and good heating efficiency is obtained.
