Abstract

PURPOSE:To make it possible to positively prevent a water leakage trouble from occurring by providing a detection part for detecting the water leakage of a hot water storage tank, a valve for interrupting water supply to a hot water storage tank, an alarm device for reporting a water leakage, and a control part for periodically actuating a valve. CONSTITUTION:Heteropole electrodes 11 and 12 are provided at a part within a drain port 8 at a predetermined interval. If a water leakage should happen and water flows at this part, heteropole electrodes 11 and 12 are energized through water resistance. A control part 13 detects the conductive state and reports it by means of an alarm lamp 14 or an alarm buzzar 15 and the water supply is interrupted by a valve provided in a water supply pipe 3 of the hot water apparatus 1. Further, a signal for periodically actuating a valve 16 is outputted from the control part at the time of starting the supply of midnight power, whereby it is possible to remove the firm adherence from a valve 16. Further, outputting of an action signal to the valve 16 from the control part 13 may be periodically actuated at the time of starting the power supply of a heating unit 5.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a hot water device configured to prevent accidents due to water leakage.

BACKGROUND OF THE INVENTION In recent years, high-rise residential buildings have become increasingly popular, and hot water systems are increasingly being installed indoors.

Under these circumstances, if a hot water system is used for a long period of time, it may cause damage to the hot water tank, piping, etc. due to corrosion in terms of service life.
Water leaks at some point.

As a countermeasure to this problem, the floor of the installation site is treated to make it waterproof, and a drain pan is installed to treat drainage.

Hereinafter, an example of the above-mentioned conventional water hot water device will be described with reference to the drawings.

FIG. 3 schematically shows the construction of a conventional water heater.

A water heater 1 that uses late-night electricity to boil water using a heating element 6
has a hot water storage tank 2 that stores as much hot water as can be used during the day, and water is supplied through a water inlet 3 provided at the bottom of the hot water storage tank 2, and the hot water in the hot water storage tank 2 is pushed up to reach the upper part. The system is such that hot water is supplied from hot water supply port 4.

When installing this hot water device 1, in order to prevent water from leaking due to damage to the hot water tank 2, etc. during long-term use, a drainper/7 should be installed at the bottom of the legs 6. It is installed carefully.

This drain pan 7 is provided with a drain port 8, and a drain pipe 9
The wastewater is then treated.

Problems to be Solved by the Invention However, with the above configuration, when the initial damage to the hot water storage tank 2, etc. is slight, the amount of water leaking is small and sufficient drainage is possible, but the amount gradually increases. If the amount exceeds a certain level, it will no longer be possible to process and the drain pan 7 will overflow. In addition, when drainage was possible, there were problems such as failure to detect water leakage and throwing away the boiled water, and high electricity bills due to long energization times. .

In view of the above-mentioned problems, the present invention provides a hot water device having a water leakage prevention function.

Means for Solving the Problems In order to solve the above problems, the present invention includes a hot water storage tank, and a detection unit that detects water leakage from the hot water storage tank, and operates based on a detection signal from the detection unit, The hot water tank has a configuration including a valve for cutting off water supply to the hot water storage tank and an alarm device for notifying water leakage, and a control section for periodically operating the valve.

Effect of the present invention With the above-described configuration, in the event that water leaks from the hot water storage tank or piping section, the detection unit detects the leakage,
Alarms are sent via the control unit using alarm devices such as lamps and buzzers. Then, the water supply is cut off by a valve installed in the water supply circuit of the hot water device.

Also, by periodically issuing a signal to operate the valve from the control section, the sticking of the valve is eliminated. In addition, in the unlikely event that the product becomes stuck, an alarm will be issued and the customer will be notified. This fruiting phenomenon can be prevented at an early stage, and the damage caused by water leakage can be reliably prevented, rather than simply being drained as shown in the conventional example.

EXAMPLE Hereinafter, a hot water device according to an example of the present invention will be described with reference to the drawings. Incidentally, the same parts as in the conventional example are given the same numbers and the description thereof will be omitted.

FIG. 1 is a configuration diagram of a hot water device in one embodiment of the present invention.

In Fig. 1, 10 is a waterproof pan using a bottom plate (hereinafter referred to as waterproof pan), 8 is a drain port, and a different polarity electrode is inserted into this.
1 and 12 are provided.

Reference numeral 13 denotes a control unit, which includes different polarity electrodes 11, 12 and an alarm lamp 14. An alarm buzzer 16 and a valve 16 that cuts off the water supply to the hot water device 1 are electrically connected.

The operation of the hot water device configured as described above will be described below with reference to FIGS. 1 and 2.

FIG. 2 is a schematic flowchart showing the operation of the present invention.

A waterproof pan 10 provided under the hot water storage tank 2 can temporarily catch water leakage. This water flows to a drain port 8 provided in the waterproof pan 10 and collects therein.

The drain port 8 is connected to a drain pipe 9 to create a drainage path to the outside of the mansilon.

The different polarity electrodes 11 and 12 are provided at a certain interval in a part of the drain port 8, and if water leaks and water flows into this part, the difference between the different polarity electrodes 11 and 12 will be interrupted. Conducted through water resistance. The control unit 13 detects this conduction state and notifies the water supply pipe 3 of the water heater 1 by an alarm lamp 14 or an alarm buzzer 16 provided on the outside of the main body of the water heater 1 or a remote control unit (not shown). Water is supplied through the valve 16 provided at the top and interrupted.

Furthermore, as shown in the flowchart of FIG. 2, the control section 13 outputs a signal for operating the valve 16 at the start of the late-night power supply, thereby making it possible to eliminate the valve 16 from sticking.

However, if the ten thousand valve 1e is stuck or malfunctions and does not operate even if a valve operating signal is applied, the abnormal state is detected by the control section 13 and the customer is notified by an alarm lamp 14 or an alarm buzzer 15.

In FIG. 2, the operation signal is output from the control unit 13 to the valve 16 at the start of the late-night power supply, but it can also be operated periodically when the power supply to the heating element 6 starts or by a timer (not shown). The purpose and effect of the present invention are also the same.

Effects of the Invention As described above, the present invention is capable of notifying the user of water leakage from a hot water storage tank, piping, etc. using an alarm such as an alarm lamp or a buzzer, and cutting off the water supply using a valve provided in the water supply piping of the hot water storage tank. .

Furthermore, by outputting a signal from the control section that causes the valve to operate periodically, it is possible to eliminate the valve from sticking.

This can prevent the amount of water leaking from increasing gradually over time, which can no longer be handled by the length of the drain pipe, and spilling into the room and downstairs, causing water leakage accidents to spread. In addition, since the valve can be prevented from sticking, more reliable water leakage prevention can be achieved. Additionally, since water leakage can be detected early, there is no need to waste electricity.
