A hot water storage tank having a water leakage alarm function according to the present invention has a double-walled structure having a hollow part (3) extending over the entire wall surface between an inner wall (l) and an outer wall (2), and is made of synthetic resin. ) is formed, and the entire area of the hollow part (3) is filled with the heat insulating material (5), and the first electrode (6) surrounding substantially the entire inner wall fl) of the heat insulating material (6) is buried. , the hot water tank (4) is connected to the first electrode (6).
This $1 electrode (6
) and a pair of second electrodes ()) are characterized by comprising a means for detecting that the electrical resistance between the electrode () and the second electrode () provided in the pair is reduced due to the conductivity of the water and issuing an alarm. Hot water tank (
4) is formed by polyethylene, and the hollow part (3) provided around the entire circumference is filled with urethane or a heat insulating material (6). The first electrode (6) is connected to the insulation material (6) in order to detect the intrusion of water (8) in the hot water tank (4) into the insulation material (5) and to notify the occurrence of water leakage. embedded within. As this electrode (6), a wire mesh, a wire rod, or a plate material is used.
It is arranged so as to cover the entire surface of the inner wall (1), and is connected to one end of the power source, and the second electrode (7) is connected to the other end of the power source.
is connected. Insulating material (5) between both electrodes +61 f7)
The water in the hot water tank (4) is electrically insulated by the inner wall f+
When water enters the insulation material (6) due to breakage of 1, both electrodes +61 and +71 are electrically connected by this leaked water, and a current flows between both electrodes (61 + 71), causing a water leak or an appropriate electrical circuit (Fig. The embodiment shown in FIG. 1 uses a metal piece as the second electrode (7), which is immersed in water stored in a hot water tank (4), and is equipped with a heat insulating material. (5) Water that entered the tank and the water tank (4)
It takes advantage of the fact that the electrical resistance of both electrodes tel +71 decreases due to the water inside. In the embodiment shown in FIG. 2, the second electrode (7) and the first electrode (6) are buried in a heat insulating material (5), and the water that enters the heat insulating material (5) can damage both electrodes. +6)
It takes advantage of the fact that the electrical resistance between +7+ decreases.

る。The above power supply and electric circuit are located outside the hot water tank (4).
The electric circuit inside the controller 1101 includes an alarm notification means (11) such as a buzzer or a
The circuit that drives the insulation (which includes the above circuit)
5) At the same time as detecting the presence of water entering the tank, the alarm notification means (II) is activated to prevent water leakage from the hot water tank (4).As described above, the present invention has a double-walled structure molded from synthetic resin. A heat insulating material is filled between the inner and outer walls of the hot water storage tank, and a first electrode is embedded in the heat insulating material that covers the entire surface of the inner wall. This book detects that the electrical resistance between the second electrode and the first electrode has decreased due to the conductivity of this water by contacting the first electrode, and issues an alarm. Cracks in the inner wall that cause water leakage from 6411 can be detected early and countermeasures can be taken immediately, especially when water storage tanks are buried underground, where water leakage can be visually confirmed. This has the advantage of being able to reliably detect water leaks even when it is impossible to do so.
