DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Drawing 1 is a figure showing the whole state where the floor heating system of this embodiment is used. As shown in this figure, a heat conductive plate 3f is provided below the floor plate 4, and a heat insulating panel 3e is provided further below the heat conductive plate 3f, and the heat conductive plate 3f and the heat insulating panel 3e are connected to each other. A predetermined distance is provided between them. In addition, a partition wall 3a (FIG. 3) is provided between the two, and an air collision space 5 that is partitioned into a plurality of parts is configured. In this air collision space 5, an air ejection pipe 2a and an air suction pipe 2b are inserted, and the air ejection pipe 2a is branched from an outward pipe 2f through which air is sent, and one air suction pipe 2b. Is branched from the return pipe 2g for sucking air.
[0010]
Here, the forward pipe 2f and the return pipe 2g are connected to the boiler 1 via the delivery pump P1 or the suction pump P2. Therefore, the air heated to a predetermined temperature by the boiler 1 is sent from the delivery pump P1 to the air ejection pipe 2a in the air circulation panel 3 via the forward passage pipe 2f which is an air circulation pipe. In the air circulation panel 3, after a part of the heat of the air is transmitted to the heat conduction plate 3f installed in the upper part, this air is sent from the air suction pipe 2b to the air circulation pipe by the suction force of the suction pump P2. Is sucked into the return pipe 2g and returned to the boiler 1, warmed to a predetermined temperature in the boiler 1, and supplied again into the air circulation panel 3. Therefore, by continuing the cycle in which the warmed air circulates as described above, the floor plate installed on the upper part of the heat conduction plate 3f of the air circulation panel 3 is indirectly warmed to a predetermined temperature and indoors. Can be heated.
[0011]
The air circulation panel 3 in the above description is composed of an air ejection pipe 2a constituted by a part of the forward pipe 2f and a part of the return pipe 2g between the heat insulating panel 3e and the heat conducting plate 3f. Each of the air suction pipes 2b to be inserted is inserted and shows the whole installed at the lower part of the floor plate 4.
[0012]
FIG. 2 is an enlarged view of the air circulation panel 3 for one section of the air collision space 5 partitioned by the partition wall 3a. As shown in this figure, an air jet pipe 2a which is a part of the forward pipe 2f branches from the side of the forward pipe 2f which is an air circulation pipe into the air circulation panel 3, and the air jet pipe 2a Air jet holes 2c, 2c,... Are formed in the upper part at predetermined intervals. Further, one end 2d of the air ejection pipe 2a is closed. An air suction pipe 2b which is a part of the return pipe 2g is disposed in parallel to the air ejection pipe 2a. One end 2d of the air suction pipe 2b is closed and the other end is an air circulation pipe. It is connected to the side of the return pipe 2g. In the upper part of the air suction pipe 2b, air suction holes 2e, 2e,... Are formed at predetermined positions so as not to coincide with the air ejection holes 2c of the air ejection pipe 2a. . The side surface of the air circulation panel 3 is partitioned from other compartments by partition walls 3a, 3a, 3b, 3c so that the air ejected from the air ejection pipe 2a does not leak into the other compartments. It has become.
[0013]
3 is a cross-sectional view taken along the line AA in FIG. As shown in this figure, the air ejection pipe 2a and the air suction pipe 2b are accommodated in the recess 3d of the heat insulating panel 3e. In addition, the side surfaces of each section are partitioned by a partition wall 3a, and a heat conduction plate 3f is installed above the partition wall 3a. And the floor board 4 is installed in the upper surface of this heat conductive board 3f. In addition to the purpose of partitioning into a plurality of air collision spaces, the partition wall 3a is provided at a predetermined height to maintain the installation state of the heat conducting plate 3f as described above. The installed heat conducting plate 3f is configured to have a predetermined distance from the heat insulating panel 3e. This distance is set within a range of several millimeters to several centimeters as described later.
[0014]
Further, as clearly shown in FIG. 3, since the air ejection pipe 2a is provided with an air ejection hole 2c formed in the upper part, the air supplied from the air ejection hole 2c is upward. In other words, the ejected air first collides with the lower surface of the heat conducting plate 3f. After that, while colliding with the surface of the partition wall 3a or the heat insulating panel 3e while changing the direction, it collides with the lower surface of the heat conducting plate 3f again.
[0015]
On the other hand, although the air suction hole 2e drilled in the air suction pipe 2b is provided in the upper part of the air suction pipe, as described above, it is located away from the air ejection hole 2c (for example, as shown in FIG. 2). Thus, since it is provided in the middle of the two air ejection holes 2c, 2c, the one in which the ejected air has become unable to move is sequentially sucked. Therefore, after the heat of the warmed air is sufficiently transmitted to the heat conducting plate 3f, it is discharged from the air circulation panel 3 to the outside.
[0016]
Next, the flow of air in the air circulation panel will be described with reference to FIGS. First, the air heated by the boiler 1 travels in the direction of the arrow 2f, which is an air circulation pipe, by the discharge force of the delivery pump P1, and part of it flows to the branching air jet pipe 2a. Then, when reaching the one end 2d of the air ejection pipe 2a, the air escape passage disappears except for the air ejection hole 2c. On the other hand, since the delivery pump P1 continues to deliver air until it reaches a predetermined pressure, the pressure of the air in the air ejection pipe 2a increases. And air blows out vigorously from the air ejection hole 2c, and the inside of the air collision space 5 formed by the heat insulation panel 3e, the partition walls 3a, 3a, 3b, 3c, and the heat conduction plate 3f is indicated by the arrows in FIG. As shown, it moves in the space while colliding with the partition 3a, the heat conduction plate 3f, and the like.
[0017]
Here, the distance A between the upper surface of the heat insulating panel 3e and the heat conducting plate 3f is set to a width of several millimeters to several centimeters, and this width A is a predetermined ratio of the air ejected from the air ejection holes 2c. Thus, it is set so as to collide with the heat conduction plate 3f. Thus, by causing the air heated by the boiler 1 to collide with the heat conduction plate 3f a plurality of times, the amount of heat transferred to the heat conduction plate 3f of the air is dramatically increased. In general, it is known that the amount of heat transfer of moving air is several times to several tens of times that of still air, and the present invention pays attention to this point. The structure of is devised.
[0018]
Further, in order to promote the collision of the air in the air collision space 5, the air in the air collision space 5 is sucked from the air suction hole 2e of the air suction pipe 2b by the suction force of the suction pump P2, and further the air It flows from the suction pipe 2b to the return pipe 2g which is an air circulation pipe, is returned to the boiler 1 as shown in FIG. 1, is warmed, and sent again to the forward pipe 2f which is an air circulation pipe by the delivery pump P1. This circulation cycle is repeated.

In the air collision space 5 formed between the heat conductive plate 3f and the heat insulating panel 3e, detour walls 8a and 8b are installed on the heat conductive plate 3f and the heat insulating panel 3e at a predetermined interval. FIG.4 (b) is a figure which shows one division of 2nd Embodiment of an air circulation panel. As shown in this figure, the heat insulation panel 3e has a recess in which the air ejection pipe 6a and the air suction pipe 7a can be disposed, and a plane that forms an air collision space 5 between the heat conduction plate 3f. The heat conducting plate 3f is installed in contact with the upper surface of the air ejection pipe 6a, the upper surface of the air suction pipe 7a, and the upper surfaces of both ends of the heat insulating panel 3e.

An ejection hole 10 a is provided on the central side surface of the air ejection pipe 10, and suction holes 9 a and 9 a are provided on the side surface near the end of the air suction pipe 9. The air circulation unit 16 has six surfaces covered with an aluminum plate or the like, and has a function of a heat conduction plate. In addition, although the figure has shown the cross section, the aluminum plate etc. exist also in the end surface of the near side and back side in a figure except the part through which the air suction pipe 9 and the air ejection pipe 10 pass. If the air circulation unit 16 is manufactured in advance in a factory or the like, a heat insulating panel 3e having a recess that can accommodate the air circulation unit 16 is installed between the joists 11 during construction as shown in FIG. 5 (b). The floor heating system according to the present invention can be easily constructed by installing the floor plate 4 on the upper surface after housing the air circulation unit 16 in the heat insulation panel 3e.

First, the air heated by the boiler 1 is sent to the header 12a by the delivery pump P1. This header 12a is for making the pressure of the air sent to the air circulation panel 3 uniform in the plurality of forward passage pipes 2f, 2f. Then, air is sent from the header 12a to the air ejection holes (not shown) in the respective sections of the air circulation panel 3 through the forward pipes 2f. Next, the air sucked into the air suction holes (not shown) of each section by the suction pump P2 is sent to the header 12b through the return pipes 2g and then returned to the boiler 1 again.
