Structure of hot water pipe inserted with heating wire

Abstract

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.

Description

TECHNICAL FIELD[0001]The present invention relates to a structure of a hot water pipe with an inserted heating wire, the structure being installed in the floor for heating and, more particularly, to a structure of a hot water pipe with an inserted heating wire, the structure comprising a low level sensor for sensing the level of working fluid filled in the hot water pipe so as to prevent overheating or malfunction caused by a shortage of working fluid, in which the low level sensor is particularly configured to stably operate so as to significantly reduce the occurrence of failures of the low level sensor, thus facilitating its maintenance.BACKGROUND ART [0002]In the era of high oil prices, the installation of a hot water pipe with an inserted heating wire to provide electric heating by inserting a working fluid together with the heating wire into the hot water pipe has recently been increased, and an example thereof is Korean Utility Model Publication No. 2008-0004828 (published on...

AI Technical Summary

Benefits of technology

The present invention provides a system for detecting the level of a working fluid in a tank or pipe. By using a low level sensor that is powered by AC power, it prevents the occurrence of accidents due to a shortage of fluid. This also reduces the likelihood of failures of the sensor, making maintenance easier and less costly. Overall, this system prevents accidents and increases safety while also improving efficiency and reducing maintenance costs.

Problems solved by technology

However, since the hot water pipe is laid in the floor and the auxiliary tank is located within an access door installed in the wall, it is not easy to frequently check the level of the auxiliary tank, and thus there has been a need to improve the convenience and maintenance.

Moreover, a cut-off terminal of a thermostat for temperature control uses direct current (DC) power converted from 220 V alternating current (AC) power, and when the above problem is to be solved by installing a low level sensor that uses the converted DC power, the generation of sparks occurs easily due to the nature of DC power, which causes damage to or malfunction of the sensor, resulting in inconvenience for maintenance.
