[Figure 8] This is a schematic cross-sectional end view illustrating the structure of a wooden house according to the second aspect of the present invention. [Modes for carrying out the invention]

[0010] The air conditioning and wiring structure of the present invention is applicable to a typical detached wooden house with interior insulation. Its characteristic feature is that it actively forms a ventilation path between the insulation material and the interior wall material in at least a portion of the indoor space on the exterior wall side of the wooden house, thereby creating a path for introducing air from the air conditioner into the indoor space. This path can also be used for the installation of electrical and communication equipment, as well as for routing their wiring and cables.

[0011] Hereinafter, the present invention will be described with reference to the drawings by way of preferred embodiments. The drawings all schematically show the structure, and only the main members are illustrated, and members not involved in the features of the present invention may be omitted from illustration.

FIG. 7 is a view showing the state after removing the heat insulating material 9 from the state of FIG. 6 cross section and corresponds to the state of FIG. 5.

[0014] The wooden house according to this embodiment, like a general wooden house, has a base 3 disposed on a foundation 1 via a packing 2, and columns 5 and intermediate columns 6 are erected and fixed on the base 3. And a large brace 4 is attached to the base 3. An outer wall material 7 is attached to the outdoor side of the column 5 as required, and an exterior material (siding) 11 is attached to the outer wall material 7 via a vertical edge 10. A floor material 8 is placed on the large brace 4 while avoiding the columns 5 and intermediate columns 6 on the indoor side of the outer wall material 7. In this embodiment, although the intermediate column 6 is also erected on the base 3 in the same manner as the column 5, the intermediate column 6 may be erected on the floor material 8 after the floor material 8 is placed. At the lower end of the outer wall material 7 usually, a drain fitting (not shown) is attached. Also, there are cases where the columns 5 and intermediate columns 6 are directly attached to the foundation 1 with metal fittings without using the base 3.

[0015] Regarding foundation 1, there are two types: a strip foundation and a slab foundation. However, in this embodiment, since it is assumed that an air conditioner will be installed under the floor, it is preferable to use a slab foundation to take into consideration the insulation of the underfloor space.

[0016] As shown in Figure 3, in the case of a two-story building, the upper and lower floors are separated by the flooring material 33 of the second floor. In the figure, 31 is a beam and 32 is the ceiling material of the first floor. Note that the ceiling material 32 is not mandatory, and the upper and lower floors may be separated only by the flooring material 33.

[0017] The wooden house according to this embodiment has an interior insulation structure, therefore the exterior wall material 7 Then, the insulation material 9 is placed in the space between adjacent columns, in this embodiment, between column 5 and stud 6.

[0018] In typical wooden houses, the interior wall material 13 is directly attached to the indoor side of the columns 5 and studs 6, so there is virtually no gap between the insulation material 9 and the interior wall material 13. However, in this embodiment, the interior wall material 13 is attached to the columns 5 and studs 6 via furring strips 12. As a result, a gap of at least the thickness of the furring strips 12 is formed between the indoor surface of the insulation material 9 and the outdoor surface of the interior wall material 13, and in this embodiment, this gap is used as a ventilation passage 21 for the air conditioning system.

[0019] In this embodiment, since it is assumed that an air conditioner is placed in the underfloor space, a through-hole 22 is formed in the floor material 8 at a position exposed in the ventilation passage 21 in order to connect the underfloor space and the ventilation passage 21. In addition, the lower end of the interior wall material 13 is separated from the floor material 8 to form a ventilation opening 24, and the ventilation passage 21 and the indoor space are connected via the ventilation opening 24. As a result, the underfloor space and the indoor space are connected via the through-hole 22, the ventilation passage 21, and the ventilation opening 24, and when an air conditioner is installed and operated in the underfloor space, the air supplied from the air conditioner is introduced into the indoor section. Since the air conditioner is installed in the underfloor space and the ventilation opening 24 is formed on the lower end side of the interior wall material 13, the air supplied from the air conditioner is mainly warm air.

[0020] Furthermore, as shown in Figure 3, in the case of a two-story building, the first and second floors are separated by, for example, the flooring material 33 of the second floor. In this embodiment, the second floor also has the same configuration as the ventilation passage 21 of the first floor, namely, a ventilation passage 21' is formed between the insulation material 9 and the interior wall material 13', a vent 24' is provided below the interior wall material 13' of the second floor, and a through hole 22' is provided in the flooring material 33 of the second floor. Through the through hole 22, ventilation passage 21, through hole 22', ventilation passage 21', and vent 24', communication is established from the underfloor space to the indoor space of the second floor, and air supplied from an air conditioner installed in the underfloor space can be introduced into the indoor space of the second floor.

[0021] In this embodiment, the ceiling material 32 is placed only on the indoor side of the interior wall material 13. However, if the ceiling material 32 reaches the beam 31, a through-hole is provided in the ceiling material 32 to connect it to the ventilation passage 21' on the second floor.

[0022] In this embodiment, the ventilation passage 21 can be used for wiring for electricity and communications. In a typical wooden house, the location of electrical and communication equipment such as lighting, switches, outlets, and intercom monitors is determined during the design phase, including the wiring. In an interior insulation structure, there is virtually no gap between the insulation material and the interior wall material, and equipment such as switches and outlets are embedded in the wall. Therefore, it was necessary to create recesses in the insulation material necessary for the above equipment before installing the interior wall material. Furthermore, if the location of the above equipment was to be changed after the interior wall material had been installed, or if new equipment was to be added, it was necessary to remove the interior wall material and redo the work.

[0023] In this embodiment, since there is a ventilation passage 21 on the exterior side of the interior wall material 13 equal to the thickness of the furring strip 12, even when installing new electrical or communication equipment, it is only necessary to make the required openings in the interior wall material 13, and there is no need to remove the interior wall material 13. Furthermore, in this embodiment, it is also possible to route wiring and cables to other indoor spaces using the through holes 22, 22' provided in the floor materials 8, 33. Moreover, even in the case of a two-story building, since the ventilation passages 21, 21' of the first and second floors are connected by the through hole 22', wiring and cables can be routed between the upper and lower floors using the through hole 22'.

[0024] Therefore, when designing a wooden house according to this embodiment, it is not necessary to determine the location of electrical or communication equipment in the area having the structure according to this embodiment, and equipment can be added or changed freely and easily after the completion of the house.

[0025] As described above, in this embodiment, since the ventilation passages 21, 21' are also used for installing electrical and communication equipment, the thickness of the furring strips 12 is preferably 3 cm or more, and since the indoor space is reduced by the thickness of the furring strips 12, the upper limit is preferably 5 cm or less.

[0026] In this embodiment, by using the furring strips 12, the through-holes 22 that connect the ventilation passage 21 and the underfloor space can be positioned on the indoor side of the foundation 3. Similarly, the through-holes 22' on the second floor are also formed on the indoor side of the beams 31. Therefore, there is no need to damage structural elements such as the foundation 3 or beams 31 to form these ventilation paths, and there is no risk of affecting strength or other effects. Furthermore, this embodiment can also be implemented in a structure where columns 5 and intermediate columns 6 are directly attached to the foundation 1 without using a foundation 3.

[0027] The air conditioning and wiring structure of this embodiment only needs to be applied to at least a portion of the exterior wall of a wooden house. Specifically, it can be applied to living rooms and other rooms along the exterior wall, while bathrooms, washrooms, storage rooms, corridors, etc., can be provided with openable and closable openings in the doors of the rooms to which this embodiment is applied, allowing for appropriate air circulation.

[0028] Furthermore, it is preferable to expel the indoor air using the ventilation device to promote the introduction of air from the ventilation passages 21, 21'. The ventilation device is preferably installed above the indoor space, and preferably on or near the ceiling. In addition, by installing the ventilation device in a location away from the indoor space to which the structure of this embodiment is applied, air can be efficiently circulated from the indoor space to other spaces.

[0029] [Second Embodiment] The second embodiment of this model is the same as the first embodiment, except that it has a configuration that assumes the air conditioner is installed in the space above the ceiling. Therefore, the configuration that differs from the first embodiment will be described, and the common configuration will be omitted from the description.

[0030] Figure 8 is a schematic cross-sectional end view of the exterior wall structure of a second embodiment of a single-story wooden house equipped with the air conditioning and wiring structure of the present invention, showing the structure in the vertical direction.

[0031] In this embodiment, similar to the first embodiment, furring strips 12 are attached to the indoor side of the columns 5 and studs 6, and the interior wall material 13 is attached to the furring strips 12, thereby forming a ventilation passage 21 between the insulation material 9 and the interior wall material 13. In this embodiment, when attaching the interior wall material 13 to the furring strips 12, a ventilation opening 24" is provided on the upper end side near the ceiling material 32'. Then, a through hole 22" is provided in the area of ​​the ceiling material 32' that is exposed to the ventilation passage 21, so that the space above the ceiling material 32' is connected to the indoor space via the through hole 22", the ventilation passage 21, and the ventilation opening 24".

[0032] In this embodiment, an air conditioner is installed in the space above the ceiling, and the air supplied from the air conditioner is introduced into the indoor space, but this air is mainly cold air.

[0033] Furthermore, in this embodiment, in the case of a two-story building, similar to the first embodiment, a ventilation passage 21 on the second floor is provided on the second floor as well, and a through-hole is provided in the ceiling material of the second floor that communicates with the space above the ceiling. Then, a through-hole is provided in the floor material of the second floor that separates the first and second floors, connecting the ventilation passages, and vents are provided on the upper ends of the interior wall materials of the first and second floors. As a result, air supplied from an air conditioner installed in the space above the ceiling can be introduced into the indoor spaces of the first and second floors through the through-hole in the ceiling material of the second floor, the ventilation passage on the second floor, the through-hole connecting the ventilation passages of the first and second floors, the ventilation passage on the first floor, and the vents provided above the interior wall materials of the first and second floors.

[0034] Furthermore, in this embodiment as well, by installing a ventilation device in a location away from the indoor space to which the structure of this embodiment is applied, air can be efficiently circulated from the indoor space to other spaces. [Explanation of Symbols]
