【発明の詳細な説明】
本発明はバイパスミキシング方式の水ボデー１を用いる
低温作動弁２付湯沸器において、温度調整ツマミ３を開

流す水ボデー１の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a water heater equipped with a low-temperature operating valve 2 that uses a water body 1 of a bypass mixing type, in which a small amount of water flows out from the low-temperature operating valve 2 when the temperature adjustment knob 3 is opened. In this case, the bypass passage 4 is closed, and when the amount of water is within the normal operating range of the water body 1, the bypass passage 4 is opened to allow water to flow.

が凍結するのを防いでいる。Recently, there has been an increase in the number of device-installed water heaters due to safety and installation space considerations. Attached to the hot water outlet side of the machine, when the outside temperature drops below freezing, water escapes from the low-temperature operating valve 2 to prevent the equipment from freezing.

して破壊する恐れがあった。However, when the temperature control knob 3 of the water body 1 is opened and the bypass passage 4 is opened, when the outside temperature drops below freezing and the low-temperature operation valve 2 operates to drain water, due to the resistance of the water passage. In this case, not much water flows to the heat exchanger 6 side, and water flows from the bypass passage 4 side, which may cause the heat exchanger 5 to freeze and be destroyed.
本発明は上記従来の欠点を解消したもので、以下その実
施例を添附図面とともに説明する。The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

器６が凍結して破壊することは７シ＜々る。- In the structure described in F, when the outside temperature falls below freezing while the hot water temperature control knob 3 of the water body 1 is open, the low temperature operation valve 2
works and water comes out, but since the amount of water is small, the part where it enters the water body 1 from the heat exchanger 5 and the bypass passage part 4
The ball 6 is accommodated in the valve seat part 7 because the water pressure difference between the valve seat and the valve seat is small. Therefore, all the water that has passed through the water body 1 flows through the heat exchanger 5, so even if the temperature drops below freezing, the heat exchanger 6 is rarely frozen and destroyed.
次に通常湯沸器を使う場合、水ボデー１を流れる水量が

器１側とバイパス通路４側に流れるようになる。Next, when using a normal water heater, the amount of water flowing through the water body 1 increases, so a pressure difference is generated between the part where the water enters the water body 1 from the heat exchanger 5 and the bypass passage part 4, and the ball 6 is separated from the valve seat portion 7 and floats up, and becomes the correct size at the spring 8. As a result, the water in the water body 1 comes to flow to the heat exchanger 1 side and the bypass passage 4 side.
以上のように本発明によれば次の効果が得られる。As described above, according to the present invention, the following effects can be obtained.
（１）水ボデー１の湯温調節ツマミ３を開にした状態で

壊することがなくなる。(1) When the outside temperature drops below freezing and the low-temperature operation valve 2 operates with the hot water temperature control knob 3 of the water body 1 open, all the water flows through the heat exchanger 5, so the heat exchanger 6 freezes. It will no longer be destroyed.
（２）構成がボール６とスプリング８だけを付は加える
だけであるので構造が簡単であり、しかも安価な価格で
つくることができる。(2) Since only the ball 6 and spring 8 are attached or added, the structure is simple and can be manufactured at a low price.
