Abstract

A water heater equipped with a leakage detecting device is provided. A flow control valve is disposed at an inlet and controls the flow rate of water flowing into the water heater. A leakage detecting device detects when water which has flowed in the water heater leaks out through pipes in the water heater due to burst of the pipes and is filled at or more than a predetermined level from the floor of a water heater case, and transmits a signal to a controller. A case protects parts in the water heater by shielding the parts from the outside. The controller controls a series of combustion processes and operation of the water heater, and closes the flow control valve, when a leakage detection signal is transmitted from the leakage detecting device.

Claims

1. A water heater equipped with a leakage detecting device, comprising:

a flow control valve that is disposed at an inlet and controls the flow rate of water flowing into the water heater;

a leakage detecting device that detects when water which has flowed in the water heater leaks out through pipes in the water heater due to burst of the pipes and is filled at or more than a predetermined level from the floor of a water heater case, and then transmits a signal to a controller;

a case that protects parts in the water heater by shielding the parts from the outside; and

the controller that controls a series of combustion processes and operation of the water heater, and closes the flow control valve, when a leakage detection signal is transmitted from the leakage detecting device.

2. The water heater equipped with a leakage detecting device according to claim 1, wherein the controller stops the operation of the water heater, when the water heater is in operation.

3. The water heater equipped with a leakage detecting device according to claim 1, further comprising a controller case that protects the controller,

wherein the leakage detecting device includes two water level detecting rods that protrude toward the floor of the water heater case from the controller case and are spaced apart at a predetermined distance from the floor of the hot water case.

4. The water heater equipped with a leakage detecting device according to claim 1, wherein the leakage detecting device includes two water level detecting rods that are attached to the wall of the water heater case, at a predetermined distance from the floor of the water heater case.

5. The water heater equipped with a leakage detecting device according to claim 1, wherein the controller includes a display that displays the operational condition of the water heater, and displays an error message through the display, when leakage is detected by the leakage detecting device.

6. The water heater equipped with a leakage detecting device according to claim 2, further comprising a controller case that protects the controller,

wherein the leakage detecting device includes two water level detecting rods that protrude toward the floor of the water heater case from the controller case and are spaced apart at a predetermined distance from the floor of the hot water case.

7. The water heater equipped with a leakage detecting device according to claim 2, wherein the leakage detecting device includes two water level detecting rods that are attached to the wall of the water heater case, at a predetermined distance from the floor of the water heater case.

8. The water heater equipped with a leakage detecting device according to claim 2, wherein the controller includes a display that displays the operational condition of the water heater, and displays an error message through the display, when leakage is detected by the leakage detecting device.
