As shown in FIGS. 1 to 3, the heat exchange ventilation pipe 40 has a tubular shape with both ends opened, and is arranged so as to surround the exhaust pipe 30.
As shown in FIG. 4, the heat exchange ventilation pipe 40 according to the first embodiment is fixed to a plurality of arc-shaped pieces 42 arranged in the circumferential direction on the outer circumference of the exhaust pipe 30 and to the inner surface of each arc-shaped piece 42. A plurality of reinforcing strips 43, a connecting portion 44 connecting the plurality of arc-shaped pieces 42 in a cylindrical shape, and a plurality of fixing screws 46 for fixing the heat exchange ventilation pipe 40 to the outer surface of the exhaust pipe 30. Have.

  In the first embodiment, the arc-shaped piece 42 is formed of an arc-shaped plate material obtained by dividing the heat exchange ventilation pipe 40 into two parts. Since each arc-shaped piece 42 is thin, thick reinforcing strips 43 are fixed to the inner surface of the arc-shaped piece 42 at a plurality of positions spaced apart from each other in the longitudinal direction of the heat exchange ventilation pipe 40.

  The connecting portion 44 is configured so that the edges of the arc-shaped pieces 42 can be connected to the positions of the reinforcing band members 43 at both circumferential edges of each of the arc-shaped pieces 42 so as to be adjacent to each other without any gap. In the first embodiment, the connecting portion 44 is adjacent to each other when the hinge portion 44a connects the two arc-shaped pieces 42 so as to be openable and closable to close the arc-shaped piece 42 in a columnar shape. It has a locking lever 44b and a locked hook 44c that can connect and fix the edges of the arc-shaped pieces 42 together.

  In the state where the locking lever 44b is disengaged from the locked hook 44c, the connecting portion 44 freely opens and closes the plurality of arc-shaped pieces 42 by the hinge portion 44a, so that the inside of the heat exchange ventilation pipe 40 The exhaust pipe 30 can be easily arranged. On the other hand, by locking and fixing the locking lever 44b to the locked hook 44c, the heat exchange vent pipe 40 can be closed and the cylindrical shape can be maintained.

  The plurality of fixing screws 46 are arranged at a plurality of locations at intervals of the circumferential direction at the position of the reinforcing strip 43. Each fixing screw 46 is screwed in the radial direction to the reinforcing strip 43, respectively. According to the plurality of fixing screws 46, the outer peripheral surface of the exhaust pipe 30 is fixed by tightening the fixing screws 46 in a state where the heat exchange ventilation pipe 40 is arranged around the outer circumference of the exhaust pipe 30. The screw 46 can be firmly pressed inward, so that the exhaust pipe 30 can be sandwiched by the plurality of fixing screws 46 and the heat exchange ventilation pipe 40 can be fixed to the exhaust pipe 30.

  In a state in which the heat exchange ventilation pipe 40 is disposed so as to surround the outer circumference of the exhaust pipe 30, the heat exchange ventilation pipe 40 and the exhaust pipe 30 are spaced apart from each other as shown in FIGS. The air passage 47 is formed therebetween.

In the first embodiment, the heat exchange ventilation pipe 40 is disposed substantially concentrically with the exhaust pipe 30, and the ventilation path 47 is provided so as to surround the entire outer circumference of the exhaust pipe 30 at equal intervals. Further, in the first embodiment, since the outer circumference of the exhaust pipe 30 is covered with the heat insulating material 33 such as rock wool, the heat exchange ventilation pipe 40 is arranged so as to surround the outer circumference of the exhaust pipe 30 covered with the heat insulating material 33. Have been.
As described above, when the ventilation path 47 is provided close to or adjacent to the exhaust pipe 30, heat exchange is performed between the gas passing through the ventilation path 47 and the exhaust passing through the exhaust pipe 30. In the first embodiment, it is possible to exchange heat appropriately via the heat insulating material 33.

  The heat exchange vent pipe 40 is attached to the roof part 12 of the gel 10 through the partition part 13 together with the exhaust pipe 30. The upper and lower ends of the heat exchange vent pipe 40 are open to the outside 14 and the indoor 15, respectively, and a vent 47 is formed between the outdoor opening 41 and the indoor opening 48.

  More specifically, the outdoor opening 41 of the heat exchange vent pipe 40 is disposed outside the partition 13 and is disposed closer to the partition 13 than the outdoor opening 31 of the exhaust pipe 30. That is, the outdoor opening 41 of the ventilation pipe 40 for heat exchange is arranged at a position where the exhaust gas discharged from the outdoor opening 31 of the exhaust pipe 30 is not taken in, and at a position where the outside air from the outdoor 14 can be taken.

  The indoor opening 48 of the heat exchange ventilation pipe 40 may be provided in the indoor 15, but is preferably a distance from the outdoor opening 41, that is, the outside air taken in from the outdoor opening 41 and flowing through the ventilation path 47 is exhausted. An indoor opening 48 is provided at a position where heat can be exchanged with the pipe 30 to be heated to a desired temperature and released to the indoor 15. Although it is not particularly limited, even if the temperature of the gas released from the indoor opening 48 is excessively cold or excessively hot, the temperature distribution in the indoor 15 tends to fluctuate. The position of the indoor opening 48 is set so as to be preferably 60 ° C. or lower, more preferably 40 ° C. or lower.

  The combustion heating device 20 having such a configuration includes a conventional combustion system in which a combustion unit 21 is installed in a room 15 partitioned by a partition unit 13 and an exhaust pipe 30 is arranged to penetrate the partition unit 13 on the roof unit 12. The heating device 20 can be easily constructed by adding the heat exchange ventilation pipe 40 later. In order to add the heat exchange ventilation pipe 40, the arc-shaped piece 42 of the heat exchange ventilation pipe 40 is opened, and the outer circumference of the exhaust pipe 30 is arranged so as to penetrate the partition 13. The ventilation pipe 40 is closed and fixed to the exhaust pipe 30 with a plurality of fixing screws 46.

  At this time, after the heat exchange ventilation pipe 40 is temporarily fixed to the outer periphery of the exhaust pipe 30 near the roof portion 12, the fixing screw 46 is loosened, and the heat exchange ventilation pipe 40 is raised along the exhaust pipe 30, The outdoor opening 41 can be disposed above the roof 12 by penetrating the part 12, and then firmly fixed by the fixing screw 46. By attaching the heat exchange ventilation pipe 40 in this manner, the heat exchange ventilation pipe 40 can be attached by work only on the indoor 15 side. By closing the arc-shaped piece 42 and tightening the fixing screw 46 with, for example, one screwdriver, the ventilation pipe 40 for heat exchange can be attached to the outer circumference of the exhaust pipe 30. The device 20 can be constructed.

  When the indoor 15 is heated by the combustion heating device 20, the fuel is burned while the air inside the indoor 15 is sucked by the combustion unit 21, and the exhaust gas generates a strong upward flow and is discharged from the exhaust pipe 30 to the outdoor 14. Accordingly, the pressure of the indoor 15 becomes lower than the pressure of the outdoor 14, so that the outside air of the outdoor 14 passes through the heat exchange vent pipe 40 having a lower resistance than the partition 13 and exchanges heat with the exhaust pipe 30. While being taken into the room 15. Thereby, the indoor 15 can be heated while being ventilated.

  Since the strength of the upward flow generated at the time of combustion increases and decreases in proportion to the amount of combustion, when the amount of combustion is large, the amount of the combustion part 21 inhaling the air in the room 15 increases and is taken in from the heat exchange vent pipe 40. The outside air volume increases. In this way, the ventilation amount of the indoor 15 is automatically and appropriately adjusted in accordance with the combustion amount, and the appropriate amount of outside air is appropriately introduced into the indoor 15 through heat exchange.

  According to the combustion heating apparatus 20 of the first embodiment, the ventilation pipe 40 for heat exchange surrounds the outer circumference of the exhaust pipe 30 and is disposed so as to pass through the partition 13, and the ventilation path opened to the indoor 15 and the outdoor 14. Since the 47 is formed, the outside air can be taken into the room 15 through the heat exchange ventilation pipe 40, and the outside air can be prevented from permeating through the partition 13 or entering through the gap of the partition 13.

  Since the ventilation path 47 is formed so as to be able to exchange heat with the exhaust pipe 30, the outside air can be heated by the ventilation path 47 and taken into the room 15, and sufficient outside air can be taken in by the heat exchange ventilation pipe 40. However, low-temperature outside air is not introduced into the room 15.

  Therefore, even if sufficient outside air is taken in and the fuel is efficiently combusted in the combustion section 21, the low-temperature outside air is not taken into the indoor 15 as it is, and the low-temperature outside air causes an excessive variation in the temperature distribution in the indoor 15. It is possible to heat the entire room as evenly as possible without causing any problem.

  In the combustion heating device 20 of the first embodiment, such heating of the indoor 15 can be performed without using other power such as electricity. Therefore, installation can be easily performed without requiring a limited installation location or preparing another power source. Further, even if a failure occurs in another power source such as a power failure as in the case of using electricity, it can be used without any problem. Further, since equipment such as a fan which needs to be driven during operation can be eliminated, there is no danger that such equipment will fail to perform ventilation and cause carbon monoxide poisoning.

  In the combustion heating device 20 of the first embodiment, since the outdoor opening 41 of the heat exchange ventilation pipe 40 is arranged outside the partition 13, the outside air can be reliably taken into the indoor 15. In addition, since the outdoor opening 41 of the heat exchange ventilation pipe 40 is disposed closer to the partition 13 than the outdoor opening 31 of the exhaust pipe 30, the outdoor openings 31 and 41 can be separated from each other. Even if the exhaust gas discharged from the exhaust pipe 30 descends to the partition 13 side along the outer peripheral wall of the exhaust pipe 30 due to the influence of the pressure on the leeward side, the heat exchange vent pipe 40 takes in the exhaust gas together with the outside air. Can be prevented.

  For example, when the wind in the outside 14 is strong, the exhaust gas discharged from the outdoor opening 31 of the exhaust pipe 30 flows down due to the negative pressure on the leeward side around the exhaust pipe 30. When the opening 41 is provided in the vicinity of the outdoor opening 31 of the exhaust pipe 30, the exhaust gas is easily taken into the heat exchange ventilation pipe 40. However, in the first embodiment, since the outdoor opening 41 of the heat exchange vent pipe 40 is disposed sufficiently away from the position of the outdoor opening 31 of the exhaust pipe 30, even if the exhaust gas flows down due to strong wind, it reaches. No exhaust is taken into the room 15.

  In the combustion heating device 20 according to the first embodiment, since the heat exchange ventilation pipe 40 is disposed around the outer circumference of the exhaust pipe 30 covered with the heat insulating material 33, the inside of the heat exchange ventilation pipe 40 is ventilated. Exhaust in the exhaust pipe 30 can be prevented from being excessively cooled by heat exchange with the outside air, a sufficient ascending flow in the exhaust pipe 30 can be secured, and a sufficient amount of air sucked in the indoor 15 into the combustion unit 21 Can be easily secured.

  According to the heat exchange vent pipe 40 of the first embodiment, the exhaust pipe 30 extending upward from the combustion part 21 and penetrating the partition part 13 can be fitted around the outer periphery and penetrating the partition part 13. , And the exhaust pipe 30, a ventilation path 47 that is open to the indoor 15 and the outdoor 14 and that can exchange heat with the exhaust pipe 30 can be formed. Therefore, by mounting the heat exchange ventilation pipe 40 on the outer periphery of the exhaust pipe 30, the above-described combustion heating device 20 can be easily realized. Accordingly, it is possible to prevent the temperature distribution of the indoor 15 from being varied due to low-temperature outside air, and easily configure the combustion heating device 20 that can heat the entire indoor as uniformly as possible.

  According to the heat exchange ventilation pipe 40 of the first embodiment, at least one arc-shaped piece 42 arranged on the outer periphery of the exhaust pipe 30 and the connecting portion 44 for connecting the arc-shaped piece 42 in a cylindrical shape are provided. By arranging the arc-shaped piece 42 around the exhaust pipe 30 and connecting the arc-shaped piece 42 in a cylindrical shape by the connecting portion 44, the outer pipe 42 can be easily mounted on the outer circumference of the exhaust pipe 30. Is possible. In particular, if such a heat exchange vent pipe 40 is used, the arc-shaped piece 42 is arranged and closed around the exhaust pipe 30 of the existing combustion heating apparatus in a state of being opened in two, and the fixing screw 46 is tightened. If the outer circumference of the exhaust pipe 30 is surrounded and fixed by the heat exchange ventilation pipe 40, the existing combustion heating apparatus can be very easily converted to the combustion heating apparatus 20 of the first embodiment.

  Further, in the exhaust pipe 30 of the first embodiment, the heat exchange vent pipes 40 have a plurality of fixing screws 46 which are arranged at a plurality of locations spaced apart in the circumferential direction and are screwed in the radial direction. Since the heat exchange ventilation pipe 40 can be fixed to the outer peripheral surface of the exhaust pipe 30 by the screw 46, the heat exchange ventilation pipe 40 is arranged on the outer circumference of the exhaust pipe 30 and the plurality of fixing screws 46 are tightened. Can be easily attached to the exhaust pipe 30. Moreover, since the heat exchange ventilation pipe 40 is directly fixed to the exhaust pipe 30, there is no need to provide a means for supporting the heat exchange ventilation pipe 40 to another member, and the configuration can be simplified.

[Second embodiment]

Can be hung.

  A cover 50 that covers an upper end of the heat exchange ventilation pipe 40 is disposed so as to surround the exhaust pipe 30 in a ring shape and is in contact with the outer peripheral surface, and an inclined wall 51 that is formed so as to have a radially downward slope from the exhaust pipe 30 side. A cylindrical wall 52 which is provided continuously on the outer peripheral side of the inclined wall 51 and has a cylindrical shape larger in diameter than the heat exchange vent pipe 40, and an attachment for attaching to the exhaust pipe 30 and the heat exchange vent pipe 40; And a downward opening. In the cover 50 according to the present embodiment, the mounting portion 53 is provided on the inclined wall 51, and the mounting portion 53 is supported by the support portion 49 c of the hanging fitting 49 disposed through the inclined wall 51.

  The cover 50 is mounted between the outdoor opening 31 of the exhaust pipe 30 and the outdoor opening 41 of the ventilation pipe 40 for heat exchange. In the mounted state, the inclined wall 51 covers the entire outer peripheral side of the exhaust pipe 30 in the outdoor opening 41 of the heat exchange vent pipe 40 at a position above and separated from the exhaust pipe 30. Further, a cylindrical wall 52 continuous from the inclined wall 51 covers the entire circumference of the outdoor opening 41 of the heat exchange vent pipe 40 at a position radially spaced apart. The cover 50 is opened downward, and can take in outside air from the partition 13 side of the cover 50.

  In order to add such a configuration to the existing combustion heating device 20, a plurality of hanging fittings 49 are fixed to the heat exchange ventilation pipe 40 and hung from the outdoor opening 31 of the exhaust pipe 30.

The heat exchange ventilation tube 40 can be easily fixed to a predetermined position of the tube 30.
In the second embodiment, the outer periphery of the exhaust pipe 30 above the outdoor opening 41 of the heat exchange vent pipe 40 to the outer periphery of the heat exchange vent pipe 40 is covered by a cover 50 that opens downward so as to allow ventilation. As a result, it is possible to prevent exhaust air from being taken in with the outside air, and furthermore, due to the weather outside 14, moisture such as rain or snow enters the ventilation path 47 of the heat exchange ventilation pipe 40 and flows into the indoor 15. Can be prevented.

The first and second embodiments can be appropriately changed within the scope of the present invention.
For example, in each of the above embodiments, the example in which the combustion heating device 20 is installed on the gel 10 has been described, but the building to be installed is not limited at all.

[Third embodiment]
7 and 8 show an exhaust pipe 30, a heat exchange ventilation pipe 40A and an air flow changing unit 60, which will be described later, according to the combustion heating apparatus of the third embodiment. The arrows shown in FIG. 8 indicate the movement of the airflow around the exhaust pipe 30. The third embodiment is different from the first embodiment in that the position and length of the heat exchange ventilation pipe 40A and the heat retaining material 33A provided in the exhaust pipe 30 and that an airflow changing unit 60 described later is newly provided are different. This is the same as the embodiment.

  In the third embodiment, the heat insulating material 33A is shorter than the heat insulating material 33 of the first embodiment, and is covered on the outer peripheral surface of the upper part of the exhaust pipe 30 exposed to the outdoors 14. Thus, it is possible to prevent the exhaust gas in the exhaust pipe 30 from being excessively cooled by heat exchange with the outside air, to prevent tar from being attached to the exhaust pipe 30, and to ensure a sufficient upflow UD1 ( (See FIG. 8), and it is easy to ensure a sufficient amount of air to be sucked into the indoor 15 in the combustion section 21 of the combustion heating device 20.

  Further, the heat exchange vent pipe 40A of the exhaust pipe 30 is shorter than the heat exchange vent pipe 40 of the first embodiment on the lower side, and passes through the partition 13 together with the exhaust pipe 30. , Is attached to the exhaust pipe 30.

In the third embodiment, an airflow changing unit 60 is newly mounted on the lower outer peripheral surface of the exhaust pipe 30.
The air flow changing portion 60 has a substantially disc shape, and is located below the heat exchange ventilation pipe 40A. The exhaust pipe 30 (a portion exposed by being shorter than the heat exchange ventilation pipe 40 of the first embodiment). ). The airflow changing portion 60 includes an insertion hole 61 through which the exhaust pipe 30 is inserted, a donut-shaped disk portion 62 extending radially from the insertion hole 61, a hanging portion 63 extending downward from the periphery of the disk portion 62, and a disk. The disk portion 62 is placed or superimposed on the upper surface of the portion 62, and includes a disk portion 62 and a heat insulating member 64 such as rock wool. Note that the heat retaining member 64 may be attached to the lower surface of the disk portion 62.

  The air flow changing section 60 is attached to the exhaust pipe 30 by the same method as the method of attaching the heat exchange ventilation pipe 40 to the exhaust pipe 30 in the first embodiment. Specifically, a plurality of screw holes (not shown) are provided at predetermined intervals in the circumferential direction of the hanging portion 63, and the air flow is changed by a plurality of fixing screws (not shown) screwed radially from the plurality of screw holes. The part 60 can be fixed and attached to the outer peripheral surface of the exhaust pipe 30 (see FIG. 3).

  As shown in FIG. 8, the disk portion 62 and the hanging portion 63 constitute an airflow receiving portion 65 that temporarily receives the rising flow UD2 from below, and the hanging portion 63 receives the received rising flow UD2 in a predetermined outer circumferential direction. An airflow outflow hole 66 for outflow is formed.

  As shown in FIG. 8, the downward flow DD passing through the ventilation path 47 between the exhaust pipe 30 and the heat exchange ventilation pipe 40 </ b> A is transmitted by the airflow changing section 60 to the airflow receiving section 65 (the heat retaining member 64) of the airflow changing section 60. And scattered in the outer circumferential direction of the airflow receiving portion 65, and the upward flow UD <b> 2 around the exhaust pipe 30 can be received by the lower surface of the airflow receiving portion 65 and flow out from the airflow outflow hole 66. .

  Thus, it is possible to avoid a direct collision between the upward flow UD2 and the downward flow DD around the exhaust pipe 30 and efficiently disperse the downward flow DD of the outside air into the room 15. In addition, the heat associated with the upflow UD2 is shut off by the heat retaining member 64 at the upper portion of the airflow change unit 60, and the generation of the further upflow UD2 can be suppressed. Therefore, the airflow can be appropriately circulated, the heating effect is enhanced, and the occupants can obtain a comfortable heating effect.

[Fourth embodiment]
9 and 10 show the heat shield sheet 70 in the heat shield structure of the gel 10 of the fourth embodiment, and FIG. 11 shows the steps of constructing the heat shield structure of the gel 10 of the fourth embodiment.

  The heat-shielding structure of the gel 10 according to the fourth embodiment covers a foundation, which is a skeleton described later, of the gel 10, and has a heat-shielding sheet 70 having at least heat-shielding and wind-shielding properties, and a base fabric forming the partition 13. 80.

  As shown in FIG. 11A, the foundation (framework) of the gel 10 is the foundation of the bellows-type wall skeleton 10 a serving as the basis of the side wall 11 of the gel 10, at least two pillars 10 b, and the roof 12. It is composed of a roof frame (beam) 10c, a door frame 10d, and a skylight frame 10e provided on the roof frame 10c. These basic frameworks (skeletons) are made of wood, lightweight steel frames and the like. The appearance of the gel 10 has a cone-shaped cylindrical shape as a whole after being constructed by the substantially conical roof frame 10c and the cylindrical wall frame 10a.

  The heat-shielding sheet 70 is a two-layer sheet in which a relatively high-strength sheet having a wind-shielding property such as a polypropylene sheet is attached to an aluminum vapor-deposited film having a heat-shielding property. Any type of sheet may be employed as long as it has properties and durability, high strength, light weight, and easy processing.

  For example, as the heat shield sheet 70, a single-layered sheet of an inexpensive aluminum-deposited film, a two-layered sheet of an aluminum-deposited film and a foamed polyethylene sheet, or aluminum-deposited on both sides of an air-sealing layer such as a bubble buffer. A three-layer sheet or the like sandwiched between films may be employed. Instead of the aluminum vapor-deposited film (a film on which aluminum is vapor-deposited and formed), a film formed by sputtering aluminum may be employed. Further, instead of the aluminum-deposited film (sheet), a copper-deposited film in which copper as another metal is deposited on the film may be employed.

  The heat shield sheet 70 includes a first sheet 71 covering the roof frame 10c constructed as a foundation, and a second sheet 72 covering the wall frame 10a.

  As shown in FIG. 9, the first sheet 71 has, as a developed shape, a substantially circular shape having a notch 71 a cut out in a radial direction from a circular positioning hole 71 c provided in the center. Then, as shown in FIG. 10, the first sheet 71 is formed by simply overlapping or butting the cut-out ends 71 b of the first sheet 71 or affixing each other with a tape or the like. In addition, a conical arrangement shape having substantially the same dimensions and substantially the same shape as the roof frame 10c can be adopted. The first sheet 71 may be provided with a notch in the radial direction instead of the notch 71a (cut), and the cut (cut) ends may be overlapped to form a conical shape. As described above, the first sheet 71 can be easily processed in accordance with the shape of the gel 10, so that there is no need for an installation by a specialist.

  Here, it is preferable to process the first sheet 71 in advance so that the vapor deposition surface faces the inside of the conical shape. Thereby, the first sheet 71 can be disposed on the roof frame 10c such that the deposition surface faces the indoor side. In addition, if both surfaces of the first sheet 71 are vapor-deposited surfaces, processing can be performed without regard to the direction of the vapor-deposited surface.

  By fitting the positioning holes 71c of the first sheet 71 around the skylight frame 10e provided on the roof frame 10c, the first sheet 71 can be positioned at an appropriate position on the roof frame 10c of the gel 10, The skeleton 10c can be appropriately covered.

  The second sheet 72 has a width substantially equal to the height of the wall skeleton 10a of the gel 10, and has a sufficient length (excluding the entrance) to cover the periphery of the wall skeleton 10a.

  Further, the second sheet 72 is a position that becomes an upper portion when the wall skeleton 10a is rolled up, and is an annular (may have elasticity) locking portion (not shown in the figure) at a predetermined interval in the longitudinal direction. ) Are provided. By locking these locking portions to the upper end of the wall skeleton 10a or the lower end of the roof skeleton 10c, the second sheet 72 can be easily temporarily attached to the wall skeleton 10a.

  By covering the skeleton of the gel 10 with the heat shield sheet 70, it is possible to prevent the outside air from entering from the partition 13 (the base fabric 80). Further, since the configuration is simple, the cost can be minimized.

  The base fabric 80 includes a first base fabric 81 such as wool felt as an intermediate layer and a second base fabric 82 such as cotton as an outer layer. The first base fabric 81 has a vertical and horizontal dimension of about 2 m × 1 m, and a plurality of first base fabrics 81 constitute an intermediate layer. The second base fabric 82 has substantially the same dimensions as the outer shape of the gel 10, and The outer layer is formed by one (single) second base fabric 82 having the same shape.

  The string 90 as the covering material attaching means is a hemp rope or the like, and the string 90 is wound around the skeleton together with the heat shielding sheet 70 or the base cloth 80 covered with the skeleton, thereby forming the heat shielding sheet 70 or the base cloth 80 into the skeleton. Can be removably attached to The covering material attaching means is not limited to the cord 90, but may be a stretchable net or the like.

Here, in the gel 10 having the heat shielding structure of the fourth embodiment, it is desirable to employ the combustion heating device 20 according to any one of the first to third embodiments.
By providing the combustion heating device 20 in the gel 10 having the heat shielding structure of the fourth embodiment, the radiant heat emitted from the combustion heating device 20 is reflected by the heat shielding sheet 70 to the indoor 15 without escaping to the outdoors 14. In addition, the occupant's perceived temperature can be increased. In addition, since the outside air is prevented from entering from the partition 13 as described above, it is possible to prevent a large variation in the temperature distribution of the indoor 15 due to the low-temperature outside air. That is, the heating effect is enhanced, and the resident can obtain a comfortable heating effect. As a result, there is no need to burn fuel excessively in the combustion heating device 20, and the amount of smoke exhausted is reduced, so that one of the factors of air pollution can be eliminated.

  In addition, since the heat shielding sheet 70 increases the airtightness of the gel 10, it is difficult to dilute harmful substances such as carbon monoxide unless the ventilation is actively performed. Accordingly, the outside air can be taken into the room 15 through the heat exchange vent pipe 40 of the exhaust pipe 30, and harmful substances such as carbon monoxide can be diluted without actively performing ventilation. There is no danger that health hazards may occur due to toxic substances such as poisoning.

  When the combustion heating device 20 according to any of the first to third embodiments is employed, the exhaust gas pipe 30 and the heat exchange ventilation pipe 40 (40A) are inserted through the skylight frame 10e (skylight) and installed. Is preferred.

  As described above, a heating unit having an excellent heating effect can be constructed by the heat shielding structure of the fourth embodiment and the combustion heating device 20 of any of the first to third embodiments.

Next, a procedure for constructing the heat shield structure of the fourth embodiment will be described.
As shown in FIG. 11 (a), a frame portion (wall skeleton 10a, pillar 10b, roof skeleton 10c, door frame 10d) which is the basis of the gel 10 is constructed in advance, and then, as shown in FIG. 11 (b). Then, the first sheet 71 previously arranged and placed on the roof frame 10c is covered, and the positioning holes 71c are fitted into the skylight frame 10e to position the first sheet 71 at an appropriate position. Then, as shown in FIG. 11C, the second sheet 72 is locked with the locking portion at the upper end of the wall skeleton 10 a, is wound around the outer peripheral surface of the wall skeleton 10 a, and the second sheet 72 is tied with the cord 90. 72 is wound around the wall skeleton 10a. Then, as shown in FIG. 11D, a plurality of first base cloths 81 are put on the roof skeleton 10c covering the first sheet 71, and are put on the wall skeleton 10a covering the second sheet 72. Wind at 90. Then, as shown in FIG. 11 (e), the second base cloth 82 is put on the roof part 12 and the side wall part 11 covering the first base cloth 81 and wound around with the cord 90, thereby heating the gel 10. A heat shielding structure that can enhance the effect can be constructed.

  And when installing the combustion heating apparatus 20 in the indoor 15, the exhaust pipe 30 and the heat exchange ventilation pipe 40A are inserted from inside the skylight frame 10e.

  As described above, the heat shielding sheet 70 (the first sheet 71 and the second sheet 72) can be easily constructed by simply placing the heat shielding sheet 70 on the skeleton portion in front of the base fabric 80. And increase in cost can be minimized. Further, by installing the combustion heating device 20 on the gel 10 having a heat shielding structure, a heating unit capable of synergistically enhancing the heating effect can be constructed.
