していた。2. Description of the Related Art Conventionally, this type of electric water heater has a structure as shown in FIG. In FIG. 2, reference numeral 1 is a container for containing a liquid 2. A heating element 3 is arranged outside the bottom of the container 1, and the temperature-sensitive element 4 is fixed to the outer periphery of the side surface of the container 1.
考案が解決しようとする課題 このような従来の構成では、液体水量が加熱体３より上
にある場合は、感温素子４の検知温度と液体温度は近似
するが、加熱体３より下に液位がある場合は、加熱体３
から容器１に直接熱が伝わるため温度差が生じ、適度の
温度に制御することが難しいという問題があった。In the conventional configuration as described above, when the amount of liquid water is higher than the heating body 3, the temperature detected by the temperature sensing element 4 and the liquid temperature are similar, but the liquid temperature is lower than the heating body 3. If there is a place, heating body 3
Since the heat is directly transferred from the container 1 to the container 1, a temperature difference occurs, and it is difficult to control the temperature to an appropriate temperature.
本考案はこのような問題点を解決するもので、液体の収
容量に関係なく液温を正確に検出し、液体量を判断する
ことを目的とするものである。The present invention solves such a problem, and an object thereof is to accurately detect the liquid temperature and determine the liquid amount regardless of the contained amount of the liquid.
課題を解決するための手段 この問題点を解決するために本考案は、液体を収容する
容器と、この容器の底部側面に装着して前記液体を加熱
する加熱体と、この加熱体より下方の前記容器の漏斗状
底面の外周端で、同加熱体に近接した位置に固定された
感温素子より構成したものである。Means for Solving the Problems In order to solve this problem, the present invention provides a container for containing a liquid, a heating body mounted on the bottom side surface of the container to heat the liquid, and a heating unit below the heating body. The thermosensitive element is fixed to the outer peripheral edge of the funnel-shaped bottom surface of the container at a position close to the heating body.
作 用 この構成により、加熱体より下に位置し、容器の底部に
固定された感温素子は、加熱体の熱が容器上方に伝わっ
ていくため、直接その温度の影響を受けない。したがっ
て、容器温度と液体温度が平均化される温度を検知する
ことにより、容器内の液体量が多少に変化しても、検出
温度は液体温度に近似することとなる。Operation With this configuration, the temperature sensitive element located below the heating element and fixed to the bottom of the container is not directly affected by the temperature of the heating element because the heat of the heating element is transferred to the upper side of the container. Therefore, by detecting the temperature at which the container temperature and the liquid temperature are averaged, the detected temperature will be close to the liquid temperature even if the amount of liquid in the container changes slightly.

In FIG. 1, reference numeral 11 denotes a container for containing the liquid 12, which has a funnel shape at the bottom so as to have a contact area with the liquid 12 and to improve the flow of the liquid 12. Reference numeral 13 denotes a heating body, which is fixed to the side surface of the bottom of the container 11 by pressure. Reference numeral 14 denotes a temperature-sensitive element, which is fixed below the heating element 13 at a position close to the heating element 13 and on the outer peripheral end of the funnel-shaped bottom surface of the container 11 and is mounted thermally favorably. Reference numeral 15 is a discharge pipe, and 16 is a discharge port. Also,
Reference numeral 17 denotes a pipe that connects the discharge port provided on the funnel-shaped bottom surface of the container 11 and the discharge pipe 15.
考案の効果 以上のように本考案によれば、加熱体の下部に取付け、
かつ加熱体近傍の容器底面に感温素子を取付ける構成に
より、加熱体から空気を伝搬して伝わる熱によって感温
素子が温度上昇の影響を受けず、液体温度に近似した温
度を検出することにより、高精度の温度コントロールを
可能とすることができる。As described above, according to the present invention, it is attached to the lower part of the heating element,
In addition, the temperature sensing element is attached to the bottom of the container near the heating element, so that the temperature sensing element is not affected by the temperature rise due to the heat transmitted through the air from the heating element, and the temperature close to the liquid temperature is detected. It is possible to enable highly accurate temperature control.
また本考案においては、加熱体より下方の容器の漏斗状
底面の外周端で、同加熱体に近接した位置に感温素子を
固定したものであるので、液位が減少し、感温素子の上
端より下に下がり、この感温素子の上端が液位上に表出
すると、容器を介して加熱体からの熱が急激に伝達され

し、空だきを未然に防止し、安全性を高めることができ
るものとなる。Further, in the present invention, since the temperature sensing element is fixed at the outer peripheral end of the funnel-shaped bottom surface of the container below the heating element, in a position close to the heating element, the liquid level is reduced and the temperature sensing element When the temperature falls below the upper end and the upper end of this temperature sensitive element appears above the liquid level, heat from the heating element is rapidly transferred through the container, and as a result, the power to the heating element is cut off. , It will be possible to prevent emptying and improve safety.
