Looking at the operation of the hot water pipe 10 configured as described above, the heating water 12 filled in the hot water pipe 10 by the heating wire 20 is heated to heat the floor. In this process, if the heating water 12 is excessively heated, the pressure will rise, and the pressure receiving device 40 receives this pressure. That is, when the pressure rises, the pressure is discharged into the case 42 of the pressure receiving device 40 along the direction of the arrow, and the moving body 46 is operated downward due to the pressure of the discharged heating water 12. Will be accepted. Then, when the pressure inside the hot water pipe 10 is lowered, the heating water 12 is introduced again into the hot water pipe 10 by the elastic means 44 supporting the movable body 46 to perform the original function. do.

If the elastic means 44 is damaged by a long time use or loses the elastic force, the heating water 12 introduced into the case 42 of the pressure receiving device 40 will not return. In this case, since the heating water 12 is insufficient in the hot water pipe 10, there is a risk of occurrence of a safety accident, there was an inconvenience in use, and the user had to check it at all times, so maintenance was inconvenient.

The present invention is devised to solve the above problems, the heating water is automatically replenished when there is a lack of heating water stored inside the hot water pipe structure of the hot water pipe is inserted into the heating wire is easy to use and easy to maintain and its objection To provide a method of installation.

In order to achieve the above object, the present invention is provided with an auxiliary tank filled with preliminary heating water at one end of the hot water pipe, and the auxiliary tank has a diameter larger than the diameter of the hot water pipe, but the upper and lower open bodies and the main body. It extends from the upper surface of the upper coupling portion to which the sealing device is fastened and extends from the lower surface of the main body is configured to include a lower coupling portion to be detachably coupled to one end of the hot water pipe.

Preferably, the main body of the auxiliary tank is formed with a transparent window on one side so that the level of the heating water filled therein can be easily checked with the naked eye.

In addition, in the installation method of the hot water pipe inserted with the heating wire, the auxiliary tank and the pressure receiving device which is installed at both ends and one end of the hot water pipe is located in the inspection door box provided with an openable door, the maintenance of the inspection door box It is characterized in that it is embedded in the wall to facilitate.

Hereinafter, with reference to the accompanying drawings will be described in more detail the structure of the hot water pipe is inserted into the heating wire of the present invention and its installation method.

2 is an exploded perspective view schematically showing a structure of a hot water pipe inserted with a heating wire according to a preferred embodiment of the present invention, and FIG. 3 is a structure of a hot water pipe with a heating wire inserted according to a preferred embodiment of the present invention. It is a schematic coupling cross section shown.

Referring to the structure (B) of the hot water pipe inserted the heating wire of the present invention with reference to Figures 2 and 3, the hot water pipe 10, the heating wire 20, the power line 22, the sealing device 30, pressure It comprises a receiving device 40 and the auxiliary tank (50).

Here, the hot water pipe 10, the heating wire 20, the power line 22, the sealing device 30 and the pressure receiving device 40 is already known and used the same in the past, the same reference numerals are used, Detailed configuration of the description will be omitted in the present invention, in the following will be briefly described for their function.

That is, the hot water pipe 10 is filled with the heating water 12 therein, is buried in a predetermined shape on the floor. In addition, the heating wire 20 is inserted into the hot water pipe 10 to be provided to heat the heating water 12, the power line 22 is connected to supply power to the heating wire 20. The sealing device 30 is to block one end of the hot water pipe 10 and the end of the auxiliary tank 50 to prevent the outflow of the heating water (12). The pressure receiving device 40 is largely a case 42 connected to the sealing device 30, an elastic means 44 provided inside the case 42, and a movable body 46 supported by the elastic means 44. It is configured to include) to prevent the breakage of the hot water pipe 10 by receiving the pressure inside the hot water pipe (10).

On the other hand, unlike the prior art in the present invention it can be seen that the auxiliary tank 50 is additionally provided, the auxiliary tank 50 has a diameter larger than the diameter of the hot water pipe 10, but the upper and lower body type 52 ) And upper and lower coupling portions 56 and 54 extending from upper and lower surfaces of the main body 52, respectively, and preliminary heating water 12 ′ is filled in the main body 52. . The lower coupling part 54 of the auxiliary tank 50 configured as described above is coupled to one end of the hot water pipe 10, and the upper coupling part 56 has a conventional hermetically sealed end of the hot water pipe 10. The device 30 is to be combined.

At this time, it is preferable that a transparent window 58 is formed on one side of the main body 52 of the auxiliary tank 50 so that the level of the preliminary heating water 12 'filled therein can be visually checked, and at the same time, maintenance It is preferable that the hot water pipe 10 is detachably attached to the hot water pipe 10 so as to be manufactured integrally with the hot water pipe 10. At this time, as the coupling method of the hot water pipe 10 and the lower coupling portion 54, a conventionally known method of coupling, nut coupling, etc. may be used, and the present invention is not illustrated in detail and is not limited thereto.

Then, the heating wire 20 passes through the auxiliary tank 50 through the auxiliary tank 50 when the heating wire 20 and the power line 22 are connected so that the preheating water 12 'is not heated. It is preferable that the wiring is made in the inside of the pipe 10, that is, the heating wire 20 will heat only the heating water 12 located in the hot water pipe 10, thereby preliminary to the auxiliary tank 50. Without the heating water 12 ′, the auxiliary tank 50 will not be heated. Therefore, as will be described later, the preliminary heating water 12 'filled in the auxiliary tank 50 is moved to the hot water pipe 10 so that the auxiliary tank 50 is heated even if the auxiliary tank 50 does not have the preliminary heating water 12'. It is implemented not to be damaged by.

"A" to "D" of Figure 4 is a schematic cross-sectional view showing the operation of the hot water pipe is inserted in the heating wire according to an embodiment of the present invention.

First, referring to "a", the pressure increases as the heating water 12 inside the hot water pipe 10 is heated, and the increased pressure gradually passes through the auxiliary tank 50 to the pressure receiving device 40. The moving body 46 will be pressurized, and the moving body 46 will receive the pressure and heating water 12 which are raised while being downward to prevent breakage of the hot water pipe 10.

Now, referring to "I", when the pressure inside the hot water pipe 10 is lowered after the operation of "A", the movable body 46 is raised by the restoring force of the elastic means 44, and the received heating water ( It can be seen that 12) is introduced into the hot water pipe 10 again.

However, when used for a long time, the elastic means 44 of the pressure receiving device 40 is damaged so that the heating water 12 accommodated in the case 42 cannot be returned to the inside of the hot water pipe 10 again. Of course. As a result, a phenomenon in which the heating water 12 is insufficient inside the hot water pipe 10 will be generated as much as the amount accommodated in the case 42, and thus, the hot water pipe 10 is easily heated, such as an unstable operation. May cause.

Therefore, in order to overcome the above problems, as the auxiliary tank 50 is provided at one end of the hot water pipe 10, the operation of the auxiliary tank 50 will be described in detail below.

Subsequently, referring to “d”, the pressure receiving device 40 cannot be restored due to the loss of restoring force of the elastic means 44 after receiving the pressure and the heating water 12. That is, the heating water 12 that was accommodated in the case 42 of the pressure receiving device 40 is not restored and remains as it is.

Although the heating water 12 accommodated in the pressure receiving device 40 is not restored, the water level of the preliminary heating water 12 ′ filled in the auxiliary tank 50 decreases and flows into the hot water pipe 10. It can be seen that. That is, the preheating water 12 ′ filled in the auxiliary tank 50 is automatically replenished into the hot water pipe 10. At this time, since only the power line 22, not the heating wire 20 is located in the auxiliary tank 50, it is to be recognized that it is not directly damaged, even if the preheating water 12 'is insufficient.

Therefore, the hot water pipe 10 is always filled with the appropriate heating water 12 by the preliminary heating water 12 ′ stored in the auxiliary tank 50 when the pressure receiving device 40 malfunctions, so that it is easy to use and maintain. There is an advantage. In addition, since the auxiliary tank 50 is provided with a transparent window 58, the user can easily confirm that the water level is lowered, so that the maintenance such as the filling of the preliminary replenishment water 12 'is more easy. have.

Referring to the drawings, both ends of the hot water pipe 10 is buried in the bottom and the auxiliary tank 50 and the pressure receiving device 40 coupled to one end of the hot water pipe 10 is an openable door 62 Located in the provided access door box 60, the access door box 60 is embedded in the wall for easy maintenance.

As a result, both ends of the hot water pipe 10 and the auxiliary tank 50 and the pressure receiving device 40 are located in the check-out box 60 provided with a retractable door 62, so that the maintenance is easy as well. Since it is located above the floor, it will be easier to supply the preliminary heating water 12 ′ stored in the auxiliary tank 50 when the heating water 12 is insufficient in the hot water pipe 10.
