Structure of hot water pipe inserted with heating wire

Abstract

The present invention relates to the structure of a hot water pipe inserted with a heating wire installed in the floor of a room for heating, and more particularly to the structure of a hot water pipe inserted with a heating wire which is provided with a low water level sensor for sensing the level of the heating water filling the inside of the hot water pipe so as to prevent the pipe from being overheated or malfunction caused by a lack of hot water, especially the low water level sensor being made to stably operate so as to considerably reduce the failing rate thereof, thus facilitating the maintenance control. According to the present invention, 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 filling the inside thereof so as to prevent an accident caused by a lack of hot water, the low water level sensor especially operating by means of the A / C current inputted through a control unit to a thermostat so as to prevent a spark caused by a D / C current, thus considerably reducing the failing rate so as to facilitate the maintenance control resulting in a decrease of the maintenance cost.

Description

technical field [0001] The present invention relates to a structure of a hot water pipe inserted with a heating wire for heating by being installed on the floor. More specifically, it relates to a structure of a hot water pipe inserted with a heating wire: The low water level sensor of the water level of the heating water inside the pipe prevents overheating or failure caused by insufficient heating water. In particular, by making the low water level sensor work stably and detecting it, the small failure rate of the low water level sensor is greatly reduced. Thereby easy maintenance. Background technique [0002] Generally, with the advent of the era of high oil prices, recently, the installation of hot water pipes with electric heating wires inserted is increasing. , to heat by electricity, the utility model publication No. 2008-0004828 (published on October 22, 2008) applied for and registered by the applicant is just one example. [0003] Referring to the above-mentione...

Problems solved by technology

[0004] However, since the hot water pipes are buried in the floor, and the auxiliary tanks are located inside the detection parts installed on the wall, there is a problem that it is difficult to confirm the water level of the auxiliary tanks at any time.

Therefore, there is a need to improve convenience and maintainability. In particular, the overload terminal of the thermostat used to adjust the temperature converts 220V alternating current (A / C) power into direct current (D / C) power for use, and if you want to Solving the above problems by installing a low water level sensor and using the DC current converted by the above temperature regulator, sparks are likely to occur due to the characteristics of DC current, and the sensor itself is frequently damaged or malfunctioned, which is inconvenient in terms of maintenance.
