Description
【発明の詳細な説明】
従来から相変態により可逆的に形状が変化す

状に変形するものである。DETAILED DESCRIPTION OF THE INVENTION So-called shape memory alloys whose shape reversibly changes through phase transformation have been known. When this alloy is made to memorize a predetermined shape (after being processed into a predetermined shape, it is heat-treated and memorized while maintaining that shape), and then heated and cooled, each shape changes at a predetermined temperature (transformation point). It transforms into a memorized shape.
本発明はこのような形状記憶合金を利用して温
水タンク内の温水の液面を一定に制御する簡単な
装置を提供するものである。 The present invention provides a simple device that uses such a shape memory alloy to control the level of hot water in a hot water tank at a constant level.

５を開くよう形状記憶されている。 Hereinafter, one embodiment of the present invention will be described based on the drawings. In the figure, 1 is a hot water tank, 2 is a hot water intake provided at the center bottom of the hot water tank 1, 3 is a valve seat of the hot water intake 2, 4 is a hot water supply pipe, 5
is a valve that opens and closes the hot water intake port 2 by contacting the valve seat 3, and is moved up and down within the hot water tank 1 via a rod 6. Reference numeral 7 denotes a coiled expandable member made of a shape memory alloy that is installed above the rod 6 and connected to the rod 6. When immersed in hot water, it acts to close the valve 5 via the rod 6, allowing hot water to flow out. The shape is memorized so that when the liquid level falls during use and the valve becomes non-immersed, it contracts and opens the valve 5.

り返す。 In the above configuration, if the hot water level is at the solid line position, the expandable member 7 is contracted and the valve 5 is opened, so that the hot water is taken into the hot water tank. Then, when the amount of hot water increases, the expandable member 7 is immersed in the hot water,
This expands and closes the valve 5.
If hot water in the hot water tank 1 is used, the expandable member 7
is not immersed in hot water, and the above operation is repeated.
従来、この種の装置は、液面の上下を液面検知

く用いられている。しかし構成が大型化する傾向
にあつた。 Conventionally, this type of device detects the rise and fall of the liquid level by shorting between electrodes for liquid level detection, etc., and uses the signal to operate an electromagnetic solenoid to open and close a valve.
A combination system of a detection member and a valve opening/closing operation member is often used. However, there was a tendency for the configuration to become larger.
しかるに本発明装置は形状記憶合金製の伸縮部
材により直接温水の検知と弁開閉力の発生による
弁の開閉を行うため、構成がきわめてコンパクト
で簡単なものとなり、動作不良の危険性がないと
いうすぐれた効果を奏している。 However, the device of the present invention uses an expandable member made of a shape memory alloy to directly detect hot water and generate valve opening/closing force to open and close the valve, so the configuration is extremely compact and simple, and it has the advantage of being free from the risk of malfunction. It has a great effect.
