BEST MODE

Hereinafter, a floor heating panel and a floor heating panel assembly including the same according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a plan view of a floor heating panel 100 according to an embodiment of the present invention, FIG. 3 is a perspective view thereof, and FIG. 4 is an enlarged view of an edge portion 170 of FIG. 3.

The floor heating panel 100 according to the present embodiment includes a substantially rectangular-shaped floor plate 110 when viewed from the top, and pipe arranging grooves 150 and 160 are provided at a top of the floor plate 110.

The pipe arranging grooves 150 and 160 are made up of water inlet and outlet pipe arranging grooves 150 and a branch pipe arranging groove 160. There is a case where the pipe arranging groove is formed by concavely forming a groove downward in the floor plate 110, or there is a case where a pair of protrusions is formed to convexly protrude upward from the floor plate 110 to allow a space between the protrusions to serve as the pipe arranging groove. Alternatively, the both cases may be applied to the pipe arranging groove.

In the present embodiment, the protrusions are provided at the top of the floor plate 110, and the space between the pair of protrusions that extend in parallel to each other serves as the pipe arranging groove 150 or 160.

More specifically, outer walls 120 protrude upward from edges of the floor plate 110 to extend along four sides of the rectangular-shaped floor plate 110, and inner walls 130 extend in parallel to the outer walls 120 to be spaced apart from the outer walls 120.

Spaces between the outer walls 120 and the inner walls 130 serve as the water inlet and outlet pipe arranging grooves 150. Intermediate walls 140 between the outer walls 120 and the inner walls 130 extend in parallel to the outer walls 120 and the inner walls 130. Accordingly, two water inlet and outlet pipes may be arranged in parallel to each other with the intermediate wall 140 interposed therebetween, and the water inlet and outlet arranging groove 150 includes an outer water inlet and outlet pipe arranging groove 150a and an inner water inlet and outlet pipe arranging groove 150b.

Meanwhile, edge portions 170 are provided at both ends of the outer walls 120 and the inner walls 130.

The edge portion 170 includes four edge openings 171 that open in four directions, curved surface portions 172 that are roundly formed between the edge openings 171 in a shape corresponding to a substantially ¼ part of a circle, and a central pin 173 positioned at a center. Here, each of the edge openings 171 is divided into two regions by the intermediate wall 140.

Meanwhile, two of the four edge openings 171 are connected to ends of the water inlet and outlet pipe arranging grooves 150 to be opened toward the water inlet and outlet pipe arranging grooves 150, and the other two openings are formed by partially cutting the outer walls 120 to be opened toward the outside.

Meanwhile, when the floor heating panel 100 of the present embodiment is provided in plural number, the edge openings 171 that are opened toward the outside are arranged to correspond to the edge openings 171 of the adjacent panel, and the water inlet and outlet pipe arranging grooves 150 of the adjacent two panels may be communicatively connected to each other through the edge portions 170.

The central pin 173 is provided at the center of the edge portion 170. The central pin 173 serves to partition paths through which several crossing water inlet and outlet pipes pass, and when external force is applied to the edge portion from the top, the central pin serves to prevent the external force from being transmitted to the water inlet and outlet pipes.

Meanwhile, outer surfaces of the edge portions, that is, outer surfaces of ends of the edges of the panel are cut in a vertical direction by a predetermined thickness to form coupling cut portions 180. The coupling cut portion 180 is cut in a shape corresponding to a ¼ part of a circular plate by a predetermined thickness, and a screw coupling hole 190 is vertically punched in a top of the coupling cut portion 180.

A coupling assistant member 610 (see FIG. 9) to be described below is inserted into the coupling cut portion 180 and the screw coupling hole 190 to fix any one panel to the adjacent panel. A method for coupling any one panel to the adjacent panel will be described below in detail at the time of describing an installing method.

Meanwhile, the branch pipe arranging groove 160 is formed inside a region surrounded by the four water inlet and outlet pipe arranging grooves 150. The branch pipe arranging groove 160 is the space between the pair of protrusions that protrudes from the top of the floor plate 110, and includes a plurality of straight line portions 161 that extends in a straight line in parallel to each other, and substantially U-shaped curved line portions 162 that are coupled to ends of the straight line portions 161. Any one of U-shaped ends of the curved line portion 162 is coupled to the straight line portion 161, so that substantially S-shaped curves are repeatedly formed as a whole.

At this time, the inner walls 130 are partially cut in portions where the water inlet and outlet pipe arranging grooves 150 and the branch pipe arranging groove 160 meet each other to form connecting cut portions 131. At this time, the connecting cut portions 131 are respectively formed at two facing water inlet and outlet pipe arranging grooves 150 at one panel 100, and the two connecting cut portions 131 are formed close to the edge portions 170 in a diagonal direction.

Meanwhile, the straight line portions 161 and the curved line portions 162 may be integrally formed as one member.

When the panel having the aforementioned structure is arranged in plural number, a shape shown in FIG. 5 is obtained. FIG. 5 illustrates a floor heating panel assembly formed by installing the pipes above the arranged panels.

Further, the T-shaped connecting member is provided with a saw tooth-shaped fixing part 401 at an outer end to allow the coupled pipes to be firmly fixed without being separated therefrom.

Meanwhile, two water inlet and outlet pipes 206 and 207 and one branch pipe 302 are arranged at the second panel 100a.

The fifth water inlet and outlet pipe 206 is firstly disposed at an upper water inlet and outlet pipe arranging groove. The fifth water inlet and outlet pipe 206 is the introducing water inlet and outlet pipe that is connected to the first water inlet and outlet pipe 202 and into which the rest warm water of the warm water introduced into the first water inlet and outlet pipe 202, which is not introduced to the first branch pipe 301 is introduced.

Accordingly, the sixth water inlet and outlet pipe 207 is the discharging water inlet and outlet pipe serving as a discharging path when the warm water introduced into the fifth water inlet and outlet pipe 206 is circulated in the panel through the second branch pipe 302 and is then discharged to the outside.

Four water inlet and outlet pipes 208, 209, 210 and 211 and one branch pipe 303 are arranged at the third panel.

The seventh water inlet and outlet pipe 208 is coupled to the second water inlet and outlet pipe 203, and is disposed at an upper water inlet and outlet pipe arranging groove on the third panel 100b. The seventh water inlet and outlet pipe 208 is the introducing water inlet and outlet pipe through which the warm water which is introduced through the external introducing pipe 201 and passes through the second water inlet and outlet pipe 203 is introduced to the third panel 100b.

The eighth water inlet and outlet pipe 209 is disposed on a side opposite to the seventh water inlet and outlet pipe 208, and the third branch pipe 303 is disposed at the branch pipe arranging groove 160 between the seventh water inlet and outlet pipe 208 and the eighth water inlet and outlet pipe 209. At this time, the eighth water inlet and outlet pipe 209 is the discharging water inlet and outlet pipe. The seventh water inlet and outlet pipe 208 and the eighth water inlet and outlet pipe 209 are arranged at the inner water inlet and outlet pipe arranging grooves 150b.

Meanwhile, the ninth water inlet and outlet pipe 210 is disposed at a right water inlet and outlet pipe arranging groove on the third panel 100b. The ninth water inlet and outlet pipe 210 is the transmitting water inlet and outlet pipe whose one end is connected to the fourth water inlet and outlet pipe 205 of the first panel 100, and is disposed at the outer water inlet and outlet pipe arranging groove 150a.

The other end of the ninth water inlet and outlet pipe 210 is coupled to the tenth water inlet and outlet pipe 211. The tenth water inlet and outlet pipe 211 is disposed at one water inlet and outlet pipe arranging groove 150 in parallel to the eighth water inlet and outlet pipe 209. At this time, the eighth water inlet and outlet pipe 209 is disposed at the inner water inlet and outlet pipe arranging groove 150b of one water inlet and outlet pipe arranging groove 150, and the tenth water inlet and outlet pipe 211 is disposed at the outer water inlet and outlet pipe arranging groove 150a thereof.

At this time, both the ninth water inlet and outlet pipe 210 and the tenth water inlet and outlet pipe 211 are the transmitting water inlet and outlet pipes.

Meanwhile, four water inlet and outlet pipe 212, 213, 214 and 215 and one branch pipe 304 are arranged at the fourth panel 100c.

The eleventh water inlet and outlet pipe 212 which is the introducing water inlet and outlet pipe disposed at an upper water inlet and outlet pipe arranging groove is connected to the seventh water inlet and outlet pipe 208 of the third panel 100b to introduce the warm water to be circulated through the fourth panel 100c.

The thirteenth water inlet and outlet pipe 214 is the transmitting water inlet and outlet pipe whose one end is connected to the sixth water inlet and outlet pipe 207 of the second panel and the other end is connected to the fourteenth water inlet and outlet pipe 215, and the fourteenth water inlet and outlet pipe is the transmitting water inlet and outlet pipe whose one end is connected to the thirteen water inlet and outlet pipe 214 and the other end is connected to the tenth water inlet and outlet pipe 211 of the third panel 100b.

In the configuration of the floor heating panel assembly, in order to smoothly circulate the warm water, an inner diameter of the water inlet and outlet pipe is larger than an inner diameter of the branch pipe. Further, when cross-sections of the water inlet and outlet pipe and the branch pipe are not circular shapes, an inner cross-section area of the water inlet and outlet pipe is larger than a cross-section area of the branch pipe.

Meanwhile, two water inlet and outlet pipes that are positioned on the two adjacent panels to be connected to each other may be integrally formed, and for example, the fourth water inlet and outlet pipe 205 and the ninth water inlet and outlet pipe 210 may be integrally formed as one member. At this time, a boundary between the fourth water inlet and outlet pipe 205 and the ninth water inlet and outlet pipe 210 is determined by which panel the pipe is positioned. That is, the part positioned on the first panel 100 is the fourth water inlet and outlet pipe 205, and the part positioned on the third panel 100b is the ninth water inlet and outlet pipe 210.

Hereinafter, a procedure in which the warm water is circulated in the floor heating panel assembly having the aforementioned structure will be described.

As the boiler (not shown) operates, the warm water is introduced in to a room or a living room to be desired to heat through the external introducing pipe 201.

Some of the warm water introduced into the first panel 100 through the external introducing pipe 201 is introduced into the first water inlet and outlet pipe 202, and the rest warm water is introduced into the second water inlet and outlet pipe 203.

At this time, some of the warm water introduced into the first water inlet and outlet pipe 202 is circulated through the first branch pipe 301, and is then discharged to the outside of the first panel 100 through the third water inlet and outlet pipe 204. Further, the some of the warm water passes through the sixth water inlet and outlet pipe 207, the thirteenth water inlet and outlet pipe 214, the fourteenth water inlet and outlet pipe 215, the tenth water inlet and outlet pipe 211, the ninth water inlet and outlet pipe 210 and the fourth water inlet and outlet pipe 205 in sequence, and is then discharged to the outside of the room or living room.

Meanwhile, the rest warm water of the warm water introduced into the first water inlet and outlet pipe 202, which does not pass through the first branch pipe 301, is introduced into the fifth water inlet and outlet pipe 206, and then passes through the second branch pipe 302 to heat the second panel 100a is heated. Thereafter, the rest warm water is discharged to the outside of the second panel 100a through the sixth water inlet and outlet pipe 207, passes through the thirteenth water inlet and outlet pipe 214, the fourteenth water inlet and outlet pipe 215, the tenth water inlet and outlet pipe 211, the ninth water inlet and outlet pipe 210 and the fourth water inlet and outlet pipe 205 in sequence, and is then discharged to the outside of the room or living room.

Meanwhile, the warm water introduced into the second water inlet and outlet pipe 203 through the external introducing pipe 201 is introduced into the seventh water inlet and outlet pipe 208, and some of the introduced warm water is circulated through the third branch pipe 303 to uniformly heat the third panel 100c. Subsequently, the some of the warm water passes through the eighth water inlet and outlet pipe 209, and the twelfth water inlet and outlet pipe 213, the fourteenth water inlet and outlet pipe 215, the tenth water inlet and outlet pipe 211, the ninth water inlet and outlet pipe 210, the fourth water inlet and outlet pipe 205 in sequence, and is then discharged to the outside of the room or living room.

Meanwhile, the rest warm water of the warm water which is introduced into the second water inlet and outlet pipe 203 and is then introduced into the seventh water inlet and outlet pipe 208, which does not pass through the third branch pipe 303, is introduced into the eleventh water inlet and outlet pipe 212, and is then circulated through the fourth branch pipe 304 to uniformly heat the fourth panel 100c. Subsequently, the rest warm water passes through the twelfth water inlet and outlet pipe 213, the fourteenth water inlet and outlet pipe 215, the tenth water inlet and outlet pipe 211, the ninth water inlet and outlet pipe 210 and the fourth water inlet and outlet pipe 205 in sequence, and is then discharged to the outside of the room or living room.

When the aforementioned structure is adopted, since a moving path of the warm water is diversified, the warm water is circulated through many regions to uniformly heat the entire floor, and since a circulating speed of the warm water becomes fast, it is possible to heat the floor at high energy efficiency by using a low-capacity boiler. Particularly, since moving distances of the warm water circulated through the respective branch pipes are the same, there is no section where a flow of the warm water is congested or becomes slow. Accordingly, it is possible to heat the floor at high efficiency by using the low-capacity boiler.

This should be understood from the fact that moving distances of the warm water passing through the first branch pipe 301, the second branch pipe 302, the third branch pipe 303 and the fourth branch pipe 304 are the same.

Meanwhile, when three pipes meet each other, the T-shaped connecting member 400 shown in FIG. 7 may be used, and when two pipes are coupled with each other at a right angle, an L-shaped connecting member 500 shown in FIG. 8 may be used. A saw tooth-shaped fixing member 501 is formed outside the L-shaped member.

Meanwhile, the floor heating panel assembly shown in FIG. 5 may be expanded as shown in FIG. 6.

That is, at least one or more panels may be provided in a horizontal direction between the first panel 100 and the second panel 100a and between the third panel 100b and the fourth panel.

Moreover, at least one or more panels may be provided in a vertical direction between the first panel 100 and the third panel 100b and between the second panel 100a and the fourth panel 100c.

A fifteenth water inlet and outlet pipe 216 which is the introducing water inlet and outlet pipe, a fifth branch pipe 305 and a sixteenth water inlet and outlet pipe 217 which is the discharging water inlet and outlet pipe are installed at the panel disposed between the first panel 100 and the second panel 100a, and the warm water introduced from the first panel 100 into the fifteenth water inlet and outlet pipe 216 which is the introducing water inlet and outlet pipe is circulated through the fifth branch pipe 305, and is then discharged toward the second panel 100a through the sixteenth water inlet and outlet pipe 217 which is the discharging water inlet and outlet pipe. At this time, one end of the fifteenth water inlet and outlet pipe 216 which is the introducing water inlet and outlet pipe is coupled to the first water inlet and outlet pipe 202 of the first panel 100, and the other end thereof is coupled to the fifth water inlet and outlet pipe 206 of the second panel 100a. One end of the sixteenth water inlet and outlet pipe 217 which is the discharging water inlet and outlet pipe is coupled to the third water inlet and outlet pipe 204 of the first panel 100, and the other end thereof is coupled to the sixth water inlet and outlet pipe 207 of the second panel.

In addition, one introducing water inlet and outlet pipe 218, a branch pipe 306, a discharging water inlet and outlet pipe 219 and a transmitting water inlet and outlet pipe 220 are installed at the panel disposed between the third panel 100b and the fourth panel 100c, and the warm water introduced from the third panel 100b into the seventeenth water inlet and outlet pipe 218 which the introducing water inlet and outlet pipe is circulated through the sixth branch pipe 306, and is then discharged toward the fourth panel 100c through the eighteenth water inlet and outlet pipe 219 which is the discharging water inlet and outlet pipe.

The warm water transmitted through the fourteenth water inlet and outlet pipe 215 which is the transmitting water inlet and outlet pipe of the fourth panel 100c is transmitted into the tenth water inlet and outlet pipe 211 which is the transmitting water inlet and outlet pipe of the third panel 100b through the nineteenth water inlet and outlet pipe 220 which is the transmitting water inlet and outlet pipe.

Therefore, it is possible to expand an arrangement structure of the panels in the horizontal direction from the basic structure of FIG. 5 by the method described above.

Meanwhile, when the panel assembly of FIG. 5 is expanded in the vertical direction, four water inlet and outlet pipes and one branch pipe are arranged at the panel disposed between the first panel 100 and the third panel 100b, and a basic arrangement structure of pipes are the same as that of the first panel.

Furthermore, three water inlet and outlet pipes and one branch pipe are arranged at the panel disposed between the second panel 100a and the fourth panel 100c, and when the fourteenth water inlet and outlet pipe 215 which is the transmitting water inlet and outlet pipe is removed from the fourth panel, a pipe arrangement structure of the panel is the same as that of the fourth panel.

Accordingly, similarly to the aforementioned structure, in addition to the pipe arrangement structure of FIG. 5, at least one or more panels may be arranged between the first panel and the third panel and between the second panel and the fourth panel.

That is, the floor heating panel assembly of FIG. 5 may be expanded in the horizontal and vertical directions, and even though the floor heating panel assembly is expanded, since the moving distances of the warm water passing through the respective branch pipes are the same, it is possible to continuously maintain the excellent effect achieved through the present invention.

A method of installing the floor heating panel having the aforementioned structure and the floor heating panel assembly using the same will be described below.

A builder arranges a plurality of floor heating panels according to the present invention on a floor. Subsequently, the builder couples any one panel to an adjacent panel. At this time, the panels are coupled using coupling assistant members 610 shown in FIG. 9.

The coupling assistant member 610 is a member having a circular plane shape and a predetermined thickness as shown in FIG. 9.

The coupling assistant member 610 has a circular plate shape having the substantially same thickness as that of the coupling cut portion 180 of the panel, and is made of a material such as rubber having elasticity.

Accordingly, as shown in FIG. 9, when four panels are coupled, after the circular plate-shaped coupling assistant members 610 are inserted into the coupling cut portions 180 formed at the edges of the four panels, screws are inserted into the screw coupling holes 190 punched at the tops of the edge portions of the panel, and the screws penetrate the coupling assistant members 610. Through this procedure, four adjacent panels are firmly fixed.

Meanwhile, when two panels are coupled, coupling assistant members having a semicircular plane shape and a predetermined thickness are used, so that it is possible to firmly fix the two adjacent panels.

By using such a method, after the panels arranged on the floor are coupled, the pipes are installed. The water inlet and outlet pipe and the water inlet and outlet pipe are connected to each other, and the water inlet and outlet pipe and the branch pipe are connected to each other. The pipes are coupled using the coupling assistant members shown in FIGS. 7 and 8.

At this time, the central pin 173 protruding upward from the center of the edge portion functions to partition the paths through which the pipe passes.

Meanwhile, after the pipes including the water inlet and outlet pipes and the branch pipes on the panels arranged on the floor are installed, a heat storage material such as red clay or mortar is poured inside the inner walls to be dried.

Thereafter, a lid is put on the panels to be fixed. The lid is a plate-shaped member whose top surface is flat. Linoleum may be laid on the lid, and an additional thermal insulating material may be provided depending on a characteristic of a building area.

Meanwhile, in the description of the present invention, any one pipe being connected to another pipe includes a case where two pipes are directly connected, and a case where two pipes are connected through another pipe or another member.

Further, the pipe should be interpreted as a term including the water inlet and outlet pipe and the branch pipe, and a concept including a hose or a pipe made of a flexible material such as rubber or synthetic resin.
