Further, since the exhaust fan is installed outside the room, the underfloor is always in a negative pressure state. Therefore, even if there is an exhaust leak under the floor, there is an excellent effect of being released outside without being diffused indoors.

  Next, embodiments of the present invention will be described with reference to the drawings. First, in FIG.1 and FIG.2, the code | symbol 11 shows an underfloor heating system house, this underfloor heating system house 11 is the pellet stove 13 installed in the room | chamber 12, and the high-temperature waste heat of this pellet stove 13 in the underfloor 19 The exhaust pipes 14a and 14b that are discharged after being introduced, the heat release box 15 that is provided in the exhaust pipes 14a and 14b to dissipate the exhaust heat to the underfloor 19, and the heat energy radiated from the heat release box 15 is stored. And a solid solid foundation 16 to be constructed.

  The pellet stove 13 is a stove that burns wood pellet fuel and has an advantage that almost no ash or smoke is emitted. It is a popular stove in recent years because it promotes the use of thinned wood and contributes to global warming countermeasures by not using fossil fuel.

  A heat-resistant small window 13a is provided at the front part of the pellet stove 13, and a connection port 13b of the exhaust pipe 14a is provided at the rear part. High-temperature exhaust heat of about 200 ° C. is discharged from the connection port 13b. This pellet stove 13 is preferably installed in the vicinity of the partition wall 17.

  The partition wall 17 is a wall that partitions the room 12 and the room 20, and a space 17 a having a predetermined width is provided inside the partition wall 17 to form an air flow path. On the other hand, the ceiling 32 is provided with a gap 32 a having a predetermined width from the lower portion 33 a of the beam 33 to form an air flow path, and the gap 32 a and the gap 17 a of the partition wall 17 communicate with each other. Therefore, the heat transmitted from the underfloor 19 rises through the gap 17a of the partition wall 17, and further diffuses through the gap 32a of the ceiling 32 into each room on the second floor, so that the heating effect on the second floor is improved. In addition, the code | symbol 34 in FIG. 1 shows the louver provided in the floor | bed 35, and the circulation of warm air is aimed at also from here.

  One end of the exhaust pipe 14a is connected to the connection port 13b and extends in the horizontal direction. The exhaust pipe 14a penetrates the partition wall 17 and then bends approximately 90 degrees and descends downward. Further, the exhaust pipe 14 a penetrates the floor 18, and the other end is connected to the heat radiating box 15 in the floor 19.

  As described above, the exhaust pipe 14a passes through the partition wall 17 and is then introduced into the floor 19 so that the room 20 on the rear side of the partition wall 17 can be exhausted even though the pellet stove 13 is not installed. It becomes warm by the heat radiation action from the tube 14a.

  The exhaust pipe 14 a in the room 20 is covered with a display shelf 21. The display shelf 21 is provided with a louver 21a from which warm air is circulated.

  The heat dissipation box 15 is formed in a horizontally long box shape using an iron plate having a thickness of about 3 mm. As an example of the size, the width is about 700 mm, the length is about 1600 mm, and the height is about 200 mm. As shown in FIG. 3, a connection port 15a of the exhaust pipe 14a is provided at the upper part on one end side of the heat radiation box 15, and a connection port 15b of the exhaust pipe 14b is provided at the other end. Further, cleaning holes 15c for cleaning are provided at a plurality of locations on the side surface.

  As shown in FIG. 4, baffle plates 22, 22... Are alternately provided on the side surfaces on both sides. By configuring in this way, high-temperature exhaust heat passing through the inside of the heat radiating box 15 is detoured while touching the baffle plate 22 (see the arrow in FIG. 4), so the residence time of the exhaust heat becomes longer and the heat dissipation effect is improved. .

  Outside the room at the other end 14c, a sirocco fan (exhaust fan) 27 is installed to smoothly exhaust the exhaust gas from the pellet stove 13 to the outside. Since the sirocco fan 27 is provided outdoors, the underfloor 19 is always in a negative pressure state, and even if there is an exhaust leak in the underfloor 19, the sirocco fan 27 is discharged outside without being diffused into the interior 12.

  As described above, the heat radiating box 15 and the exhaust pipe 14 b are installed in the lower floor 19 in the lower part of the room 20. Therefore, although the room 20 is not provided with the pellet stove 13, heat is transmitted from the underfloor 19, so that the heating effect is good in combination with the heat radiation action from the exhaust pipe 14 a described above. In addition, the code | symbol 36 in FIG.1 and FIG.2 shows the louver provided in the floor | bed 18, and the circulation of warm air is aimed at also from here.

  The concrete solid foundation 16 is placed over the entire surface of the floor 19 and has a thickness of about 150 mm, and a reinforcing bar 28 is arranged inside. The solid solid foundation 16 serves as a heat storage unit that stores heat energy radiated from the lower surface of the heat radiating box 15 mainly.

  In the solid concrete foundation 16, a barley stone sheet 29 is laid in the vicinity of the heat radiating box 15 and the exhaust pipe 14b. Since the barley stone sheet 29 has a property of emitting far infrared rays, a large amount of far infrared rays are emitted by heat radiation from the heat radiation box 15 and the exhaust pipe 14b. Therefore, the far infrared rays are transmitted to the entire building together with the heat transmitted from the underfloor 19 to warm the human body from the core.

  A heat insulating material 30 is laid on the lower part of the solid concrete foundation 16 to a thickness of about 100 mm, a moisture-proof sheet is laid on the lower part, and a crushed stone 31 is about 100 mm thick on the lower part. Is laid.

  The underfloor heating system house 11 configured as described above is constructed to be highly airtight and highly heat-insulated by a conventional wooden frame construction method. And since it comprised so that the high temperature exhaust heat of the pellet stove 13 might be introduced into the underfloor 19, the exhaust heat of the pellet stove 13 which was thrown away outside conventionally can be utilized effectively as a heat source for underfloor heating.

  And since the room | chamber 12 becomes warm by operation of the pellet stove 11, since heat dissipation to the underfloor 19 of the heat radiating box 15 and the heat storage of the concrete solid foundation 16 are performed simultaneously, heat is transmitted from the underfloor 19 as well. Sufficient heating effect can be obtained in every corner of the building. Moreover, since the heat radiation from the solid solid foundation 16 is continued even after the pellet stove 11 is turned off, the heating effect can be maintained for a long time.

  Furthermore, since the heat transmitted from the underfloor 19 rises through the gap 17a of the partition wall 17 and further diffuses through the gap 32a of the ceiling 32 into each room on the second floor, the heating effect not only on the first floor but also on the second floor Is also good.
