  In the floor heating panel configured to lay the pipe as described above, a structure that can cope with the expansion and contraction of the pipe is required. In addition, there is a need to provide a floor heating panel that can be installed on a floor having a complicated shape by increasing the degree of freedom of pipe arrangement patterns. Furthermore, it is required to increase the laying rate per unit area.

  Accordingly, the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a floor that can flexibly cope with expansion / contraction of pipes and can realize a wider arrangement pattern of pipes than before. It is providing the floor heating installation provided with the heating panel and the said floor heating panel.

  In order to solve the above problems, a floor heating panel according to the present invention is provided with a plurality of ridges extending in parallel to each other along at least one side of the panel body and parallel to each other. A heat storage type floor heating panel configured as a concave groove extending along the same direction for arranging a heat medium flow pipe, between the adjacent raised portions and the raised portions. At least one of the two ends of the raised portion along the same direction is formed on the inner side of the end of the floor heating panel, and the floor heating panel is perpendicular to the equal direction. When the above-mentioned groove is seen by cutting in any direction, the above-mentioned ridge and the other of the above-mentioned panel body constitutes the above-mentioned groove from the one end toward the end of the floor heating panel. Above bumps It is characterized in that extending at least twice the length than the maximum length of the length in each other equal ridge height position in the.

  The floor heating panel having the above-described configuration can flexibly cope with expansion and contraction of the heat medium flow pipe (pipe), and can realize a wider pattern of the heat medium flow pipe than before.

  Specifically, according to the floor heating panel according to the present invention, since the concave groove extending along the same direction is formed, the heat medium flow pipe can be disposed in the concave groove. And at least one tip of the two tips of the raised portion along the same direction is formed inside the end of the floor heating panel, and the floor heating panel is arranged with respect to the equal direction. When the body is cut in a vertical direction and the groove is viewed, the main body forms one of the ridges and the other constituting the groove from the one end toward the end of the floor heating panel. And extending at least twice as long as the maximum length of the ridges at the same height of the ridge.

  As a result, first, when one heat medium flow pipe is bent into a U-shape and arranged in one groove and, for example, a groove located next to the groove, U Since the panel body that arranges the bent part in a letter shape is formed in a space wider than the width of the groove, the heat medium flow pipe expands and contracts when hot water is passed through the heat medium flow pipe. However, the bent portion of the heat medium flow pipe is not ruptured, and inconvenience is hardly caused in the arrangement state. Here, the inconvenience of the arrangement state means that, for example, when the bent portion of the heat medium circulation pipe is arranged in a groove having a width where one heat medium circulation pipe can be arranged, the heat medium circulation pipe expands and contracts. It means that it becomes difficult to realize the desired heating performance because the bent portion of the medium flow pipe is detached from the groove. According to the configuration of the present invention, such inconvenience hardly occurs and the reliability of the heating function can be improved.

  And according to said structure, when considering one long heat-medium distribution pipe arrange | positioned in a certain one ditch | groove, this heat-medium distribution pipe is bent in a U-shape, When disposing in another groove different from the groove, at the one end of the raised portion, the heat medium flow pipe is connected to the groove adjacent to the certain groove or further adjacent to the groove. , And can be disposed in a desired groove.

Already formed. Therefore, if the heat medium flow pipe is arranged as described above, such as a groove next to a certain groove, or a groove next to the groove, the groove where the heat medium flow pipe is not disposed. Will occur. That is, in the case of the prior art, the type of arrangement pattern of the heat medium flow pipe is limited in advance. On the other hand, according to the structure of this invention, since the part which arrange | positions the bending part of a heat carrier flow pipe is comprised widely, compared with the past, there exists a freedom degree in an arrangement | positioning pattern.

  Moreover, it is preferable that the floor heating panel which concerns on this invention is formed in the said edge of the said floor heating panel with the protrusion part which protruded from the said single side along the said edge.

  As a result, the protruding portion protruding from the one surface can contact the bent portion when the heat medium flow tube is bent to guide the bending more appropriately, and by contacting, the heat medium flow tube Heat can be stored by the protrusions.

  Further, in the floor heating panel according to the present invention, the one end of the raised portion has a round shape that is convex toward the end of the floor heating panel, and the raised portion of the protruding portion has the above-mentioned shape. It is preferable that the part facing the one end has a concave shape toward the end of the floor heating panel along the round shape.

  According to said structure, the said protrusion part and the said convex round shape of the said front-end | tip of the said protruding part can guide the bending of a heat carrier flow pipe.

  Further, in the floor heating panel according to the present invention, the protruding portion has a cutout portion extending from the position facing the concave groove in the protruding portion to the end of the floor heating panel on the extended line of the concave groove. It is preferable to be provided.

  According to the above configuration, since the concave groove and the cutout portion of the projecting portion are in a straight line, the heat medium flow pipe disposed in the concave groove is passed through the cutout portion as it is and the floor. Can be pulled out to the end of the heating panel. That is, according to the present invention, three or more floor heating panels according to the present invention are arranged along the extending direction of the concave groove, and one of the three is heated along the extending direction of the concave groove. A medium distribution pipe can be arranged. Specifically, the first, second, and third floor heating panels (according to the present invention) are arranged in this order along the extending direction of the groove, and arranged in the groove of the first floor heating panel. The heat medium flow pipe to be passed through the notch and disposed in the groove of the second floor heating panel, and further through the notch and disposed in the groove of the third floor heating panel. In addition, at the end of the third floor heating panel, the heat medium flow pipe is turned (bent) in the panel body extending from the one end of the raised portion, so that another concave groove of the third floor heating panel is provided. It is possible to arrange the cutout portion, the second floor heating panel, the cutout portion, and the first floor heating panel in this order.

  Here, if a floor heating panel not provided with the notch is used, even if three are arranged in the same manner as described above, a single heat medium flow pipe as in the present invention described above is used. Cannot be placed in a straight line across the three floor heating panels. In other words, in the case of the present invention, the structure of the floor heating panel of the present invention can cope with whether the arrangement shape of one heat medium flow pipe is a straight portion or a turn portion. Therefore, compared with the structure which needs to employ | adopt the structure of another floor heating panel for each of a linear part and a turn part, versatility is high.

  Moreover, as will be described later, the floor heating panel of the present invention is preferably manufactured by blow molding. Therefore, according to the configuration of the present invention as described above, if one mold is prepared, the floor heating panel of the straight part and the floor heating panel of the turn part can be manufactured. In addition, a reduction in manufacturing cost can be realized.

  Moreover, it is preferable that the floor heating panel which concerns on this invention is the structure which filled the heat storage material inside the hollow structure.

  Many heat storage materials change their form greatly, such as causing a phase change at the temperature at which they are stored. Therefore, it becomes possible to cope with the phase change of the heat storage material by filling the inside with the heat storage material.

  Moreover, in order to solve said subject, the floor heating equipment which concerns on this invention is a floor heating panel of an above-described structure, the heat-medium distribution pipe arrange | positioned along the said ditch | groove, and the said heat-medium distribution pipe. And heating means for heating the medium to be circulated.

  As described above, the floor heating panel having the above configuration can flexibly cope with the expansion / contraction of the heat medium flow pipe (pipe) and can realize a wider pattern of the heat medium flow pipe than before. Therefore, a reliable heating function can be realized. Therefore, by providing such a floor heating panel, a highly versatile floor heating facility can be provided.
