STRUCTURE OF HOT WATER PIPE INSERTED WITH HEATING WIRE

摘要

A structure of a hot water pipe inserted with a heating wire installed in the floor of a room for heating. The structure of a hot water pipe inserted with a heating wire is provided with a low water level sensor for sensing the level of the heating water filling the inside of the hot water pipe. The structure is configured to prevent the pipe from being overheated or to malfunction by a lack of hot water. The low water level sensor is configured to stably operate so as to reduce the failing rate thereof, thus facilitating maintenance control. A low water level sensor provided in an auxiliary tank or one side of a hot water pipe senses the level of the hot water to prevent an accident caused by a lack of hot water. The low water level sensor operates using A/C current inputted through a control unit to a thermostat.

主权项

1. A structure of a hot water pipe with an inserted heating wire, the structure comprising:
a hot water pipe filled with a working fluid and installed in a floor; a sealing means operatively connected to an upper end of the hot water pipe configured to seal the inside thereof; a heating wire disposed in the hot water pipe configured to heat the working fluid; a power wire coupled to the heating wire; a thermostat operatively connected to the power wire to supply external power and, to control the overall operation; a low level sensor which is installed at one side of the hot water pipe and configured to detect the level of the working fluid filled therein; and a controller electrically coupled to the thermostat to control the low level sensor to be operated by AC power, which is input to the thermostat or input from the outside, by reducing the voltage of the AC power and, at the same time, to transmit a detection signal to the thermostat, the controller including a converter to convert the AC power to DC power and supply the DC power to the thermostat.
