Rolled floor heating mat using hydro

Abstract

In a long hot water mat, straight parts ( 4 a ) of a hot water pipe ( 4 ) are laid lengthwise in a long mat body ( 2 ) and U-shaped turning parts ( 4 b ) of the hot water pipe are placed at locations near the opposite ends ( 2 b ) of the mat body ( 2 ). Slits ( 7 ) are formed at regular intervals in the lower surface of the mat body ( 2 ) so that the slits cross the mat body ( 2 ) in directions crossing the straight parts ( 4 a ) of the hot water pipe ( 4 ). The hot water mat having a heat dissipating sheet ( 6 ) thereon can be rolled from an end of the mat body ( 2 ), with the heat dissipating sheet being placed inward, due to the slits ( 7 ) so that the mat can be easily moved using an elevator or can be easily moved into a room while avoiding a reduction in the size of the mat.

1 . A long folding hot water mat for floor heating, comprising:
 a. a long flat panel-shaped mat body;   b. a piping groove for a hot water pipe, the piping groove including straight groove parts formed lengthwise on an upper surface of the mat body, and U-shaped turning groove parts alternately connecting ends of neighboring straight groove parts to each other, so that the piping groove forms a zigzag shape;   c. a hot water pipe laid in the piping groove and dissipating heat using hot water flowing in the hot water pipe;   d. a heat dissipating sheet attached to the front surface of the mat body having the hot water pipe, thereby integrating the hot water pipe with the mat body into a single body; and   e. folding slits formed at regular intervals in a lower surface of the mat body in directions perpendicular to straight parts of the hot water pipe.   
     
     
         2 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the slits formed in the lower surface of the mat body have a V-shaped, I-shaped or U-shaped cross-section. 
     
     
         3 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the slits are formed to reach a predetermined depth into a thickness of the mat body. 
     
     
         4 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the slits are formed to a depth that cuts through an entire thickness of the mat body. 
     
     
         5 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the slits are formed in one mat body in a manner of a combination of slits that are formed to reach a predetermined depth and slits that are formed to a depth cutting through an entire thickness of the mat body. 
     
     
         6 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the mat body is made of a foam body. 
     
     
         7 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the heat dissipating sheet attached to the upper surface of the mat body is made of a thin aluminum sheet. 
     
     
         8 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the piping groove formed in the mat body and the hot water pipe laid in the piping groove are formed for one system or for plural systems in one mat body. 
     
     
         9 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein the hot water mat can be rolled from a lengthwise end thereof, with the heat dissipating sheet being placed inward, due to the slits. 
     
     
         10 . The long folding hot water mat for floor heating as set forth in  claim 1 , wherein width support bars are inserted into the mat body at locations between the slits so that the width support bars are in parallel to the slits, the width support bars having a thickness equal to a thickness of the mat body, with pipe seat grooves having a U-shaped cross-section being formed on a surface of each of the width support bars at locations at which the hot water pipe crosses each of the width support bars.
