Description

  The present invention relates to a heating structure used for a wooden building or a reinforced concrete building constructed as a general house.

  Conventionally, heating equipment such as oil stoves, gas stoves, electric stoves or kotatsu has been used as heating means for ordinary houses, but air conditioners have been used, but in recent years, floor heating systems that are effective in heating feet have attracted attention. Collecting. In addition, facilities capable of cooling and heating the entire house including floor heating have been proposed (see, for example, Patent Document 1).

  In the air conditioning system described in Patent Document 1, a water pipe is installed in the underfloor concrete placed at a position lower than the floor surface, and the air in the underfloor space heated by the hot water supplied into the water pipe is opened to the floor board. The indoor space is warmed by raising the air from the vents to the room, and the floor surface is also warmed by heat radiation from the underfloor concrete.

Japanese Patent Laid-Open No. 11-230575

  The air conditioning system described in Patent Document 1 should be able to efficiently heat the indoor space because the air in the underfloor space heated by the hot water of the water pipe piped in the underfloor concrete is sent directly into the room through the vent. However, the reality is that the heating efficiency is not good.

  In addition, since the vents are opened in the floor board, articles may be accidentally dropped under the floor or the legs may be caught while walking. Furthermore, since furniture or a desk cannot be placed on the vent hole, the effective space in the room is substantially reduced.

  The problem to be solved by the present invention is to provide a heating structure capable of efficiently heating with less energy without dropping articles under the floor by mistake or narrowing the effective space in the room.

  The heating structure of the present invention includes a heat generating means disposed between a floor surface of the building and the ground, a ventilation path provided in the wall of the building for raising and diffusing an air flow, and the heat generation. And an introduction path through which air heated by the means flows into the ventilation path.

  With such a configuration, the air between the floor of the building and the ground is warmed by the heat generating means, and the warmed air flows into the ventilation path in the wall of the building through the introduction path. Since the interior is raised and diffused, the heat insulation of the wall body is enhanced, and the room can be efficiently heated. Further, the floor surface and the wall surface are warmed by the heat generating means or the air heated by the heat generating means, which is effective in increasing the heating efficiency. Furthermore, since it is not necessary to provide an opening for allowing the air heated by the heat generating means to flow into the room, an article is not accidentally dropped under the floor or an effective space in the room is not narrowed.

  In addition, since the heat generating means is not limited, various heat sources such as an electric heating member, a heat storage member, and a thermal fluid can be used. For example, hot water heated by an electric water heater that operates at midnight power with low electricity charges is circulated. If the piping to be provided is provided, the energy cost can be reduced.

  Here, if the introduction path is provided in the joint area between the floor and the wall, the air warmed by the heating means smoothly flows into the ventilation path without adversely affecting the structure of the building. Can be made.

  On the other hand, if the ventilation path communicates with the attic space of the building, the air heated by the heat generating means rises and diffuses in the ventilation path, and then flows into the attic space. Diffusion is promoted and heating efficiency can be increased. In addition, the air heated by the heating means flows into the attic space, so that the heat insulation of the attic space is also improved, and the heat from the warm air in the attic space is radiated to the room below the ceiling, improving heating efficiency It is effective for.

  In this case, it is desirable to provide exhaust means for discharging the air in the attic space to the outdoors in the attic space. With such a configuration, the negative pressure generated in the attic space by the action of the exhaust means promotes the movement of air from the inside of the ventilation path to the attic space, so the air ventilation path warmed by the heating means The inflow into the inside and the rise and diffusion in the ventilation path are also promoted, and the heating efficiency can be further increased. In addition, if the exhaust means is operated without operating the heat generating means, the heat insulation of the wall body in summer can be enhanced by the air that rises and diffuses the ventilation path, which is effective in improving the cooling efficiency. .

  Furthermore, an opening that communicates with the ceiling space formed between the ceiling of the room in the building and the floor of another room located above the ceiling is provided in a part of the ventilation path. You can also. With such a configuration, at least a part of the air that rises and diffuses in the ventilation path is sent to the ceiling back space formed between the upper and lower living rooms, and the ceiling of the lower living room and the upper living room Since the floor of the room is warmed, the heating efficiency of the living room can be further increased.

  According to the present invention, it is possible to provide a heating structure capable of efficiently heating with less energy without dropping articles under the floor by mistake or narrowing the effective space in the room.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial sectional view showing a heating structure according to the first embodiment of the present invention.

  In the heating structure shown in FIG. 1, a concrete foundation 14 is placed on a foundation structure 13 formed in the ground 12, and a lightweight concrete layer 18 is provided on a heat insulating material 19 laid on the concrete foundation 14. It has been. The lightweight concrete layer 18 is formed at a position higher than the ground surface G, and a hot water pipe 15 serving as a heating means is provided in the lightweight concrete layer 18. A ventilation path 10a is provided between the outer wall material 10m and the inner wall material 10n constituting the wall body 10w of the building 10, and is introduced for allowing the air in the underfloor space 10b heated by the hot water pipe 15 to flow into the ventilation path 10a. A path 10c is provided in a joint region between the floor surface 10f and the wall body 10w. A hot water supply device (not shown) for supplying hot water to the hot water pipe 15 is also provided.

  With such a configuration, the air in the underfloor space 10b of the building 10 is warmed by the radiant heat from the lightweight concrete layer 18 heated by the hot water pipe 15, and this warmed air (hereinafter “warm air”). ) Flows into the ventilation path 10a in the wall body 10w via the introduction path 10c, and rises and diffuses in the ventilation path 10a, so that the heat insulation of the wall body 10w is enhanced and the inside of the living room 10u is efficiently heated. can do. Further, since the interior of the living room 10u is warmed by the radiant heat from the floor surface 10f and the inner wall material 10n heated by warm air flowing through the underfloor space 10b and the ventilation path 10a, it is effective for improving the heating efficiency of the living room 10u.

  In addition, an opening 10h communicating with the ceiling space 16 formed between the ceiling 10t of the living room 10u in the building 10 and the floor surface 10s of the second-floor side living room 10r located above the ceiling 10t, 17a is provided in a part of the ventilation path 10a. The opening 10h is provided between the horizontal member 17 and the peripheral edge of the ceiling 10t, and the opening 17a is formed by cutting out a part of the upper surface of the horizontal member 17 into a concave shape. At least part of the warm air that has risen in the ventilation path 10a flows into the ceiling space 16 from the opening 10h, flows and diffuses in the space, and then flows again into the ventilation path 10a through the opening 17a. And rise.

  Thus, since the ceiling 10t of the living room 10u and the floor surface 10s of the living room 10r are respectively warmed by the warm air flowing into the ceiling back space 16 from the ventilation channel 10a via the opening 10h, the heated ceiling 10t and Heating efficiency in the living rooms 10u and 10r can be increased by radiant heat from the floor surface 10s.

  On the other hand, since the upper end portion of the ventilation path 10a communicates with the back space 10d of the building 10 through the vent 10e, the warm air rising in the ventilation path 10a passes through the vent 10e. It flows into the space 10d. For this reason, the rise and diffusion of warm air in the ventilation path 10a are promoted, and the heating efficiency can be increased. Moreover, when warm air flows into the shed space 10d and diffuses, it is possible to improve the heat insulating property and heat retention of the shed space 10d.

  As shown in FIG. 1, since the exhaust device 10g is arranged in the attic space 10d, the air in the attic space 10d can be discharged to the outdoors by operating the exhaust device 10g as necessary. it can. Further, when the exhaust device 10g is operated, a negative pressure is generated in the cabin space 10d, so that the movement of warm air from the ventilation path 10a to the cabin space 10d is promoted. Therefore, inflow of warm air in the underfloor space 10b into the ventilation path 10a and rise and diffusion in the ventilation path 10a are promoted, and heating efficiency is further increased.

  In the summertime when heating is not required, if the exhaust device 10g is operated in a state where the hot water supply to the hot water pipe 15 is stopped, the air in the underfloor space 10b is changed to the ventilation path 10a, the ceiling space 16 and the back of the hut. It flows through the space 10d and is discharged outside. As a result, the temperature rise of the wall body 10w, the ceiling back space 16 and the shed space 10d can be suppressed, and the heat insulation of the wall body 10w and the like is enhanced, which is effective in improving the cooling efficiency in summer.

  Since the introduction path 10c is provided between the base 10j and the joist 10k, which is a joint area between the floor surface 10f and the wall 10w, the warming of the underfloor space 10b can be performed without adversely affecting the structure of the building 10. Air can smoothly flow into the ventilation path 10a. Therefore, there is no need to provide an opening or the like on the floor surface 10f for allowing warm air in the underfloor space 10b to flow into the living room 10u. For this reason, it does not accidentally drop articles from the opening to the floor or narrow the effective space of the living room 10u. Further, since a heat insulating material 19 is interposed between the lightweight concrete layer 18 and the concrete foundation 14, the heat of the lightweight concrete layer 18 heated by the hot water pipe 15 passes through the concrete foundation 14 and the ground 12. Escape to the side can be prevented.

  In addition, although the hot water supply apparatus (not shown) supplied to the hot water pipe 15 is not specifically limited, For example, if the hot water heated with the electric water heater using the midnight power with an inexpensive electric bill is used for daytime heating Heating costs can be greatly reduced. In addition, hot water heated by an electric water heater operating at midnight power is supplied to the hot water pipe 15 at night and circulated to store heat in the lightweight concrete layer 18, and the supply of hot water is stopped during the day. Heating with the heat accumulated in the layer 18 can further reduce heating costs.

  Moreover, since it is the structure which pipes the hot water pipe 15 in the lightweight concrete layer 18, it can perform piping construction simultaneously in the case of foundation construction. For this reason, construction is easy and the construction period is not delayed. Furthermore, since the lightweight concrete layer 18 is located at a position higher than the ground surface G, water is not generated from the joints.
