  Below, the outline of the house 1 which has the heating structure which concerns on one Embodiment of this invention first using FIG.1 and FIG.2 is demonstrated.

  The house 1 is a multi-story (for example, 2nd floor) building for a person (resident) to live in. In FIG. 1, a characteristic portion of the first floor portion of the house 1 is schematically shown. As shown in FIG. 1, the house 1 has two types of floor portions having different heights on the first floor portion which is the same floor. Here, of the two types of floor portions, the floor portion having the higher height is referred to as “general floor portion 10”, and the floor portion having the lower height is referred to as “low floor portion 20”.

  The general floor portion 10 is a floor portion having a normal height of the first floor portion of a general house. The floor surface of the general floor portion 10 is a first floor reference floor surface (1F floor line). The floor surface of the general floor portion 10 is located above the top end 44 of the foundation 40 described later (see FIG. 2). The space having the general floor 10 is used as, for example, a kitchen 11 or a dining room 12.

  The low floor 20 is a floor having a lower height than the general floor 10. The floor surface (down floor line) of the low floor portion 20 is provided at a position lower than the reference floor surface on the first floor. The floor surface of the low floor portion 20 is provided at a position lower than the top end 44 of the foundation 40 described later (see FIG. 2). The space having the low floor 20 is used as a living room 21, for example.

  Below, the structure of the space which has the low floor part 20, ie, the living room 21, is demonstrated using FIG.

  In addition, in FIG. 1, the wall part facing the outdoors shall be provided in the near side of a paper surface, and the description of the said wall part shall be abbreviate | omitted suitably for convenience of explanation.

  The living room 21 is arranged on the outdoor side of the first floor portion of the house 1. The living room 21 is adjacent to a space (specifically, the kitchen 11 and the dining room 12) having the general floor 10 on the indoor side. A sofa 22 is arranged in the living room 21. The living room 21 is partitioned into a substantially rectangular shape in plan view by three wall portions arranged on the outer edge (periphery) of the low floor portion 20 in addition to the wall portion on the front side of the paper surface. The three wall parts include an outdoor side wall part 30, a first indoor side wall part 31, and a second indoor side wall part 32.

  The outdoor side wall part 30 is a wall part facing the outdoors in the living room 21, similarly to the wall part on the front side of the paper surface. The outdoor side wall part 30 has the window part 23 opened toward the outdoors in the middle part of the up-down direction. A detailed description of the structure of the outdoor side wall 30 will be described later.

  The first indoor side wall part 31 and the second indoor side wall part 32 are wall parts arranged at the boundary between the kitchen 11 and the dining room 12 in the living room 21, respectively. Specifically, the first indoor side wall 31 is disposed at the boundary with the kitchen 11 in the living room 21. In addition, the second indoor side wall 32 is disposed at the boundary with the dining room 12 in the living room 21.

  The counter unit 236 is a top plate of the lower wall unit 230. The counter unit 236 is placed on plywoods 243 and 243 installed from the outdoor side to the indoor side of the lower wall unit 230. The plywoods 243 and 243 are plate members that extend in the indoor and outdoor directions in a side view. The indoor side ends of the plywoods 243 and 243 are placed on the lower wall heat insulation panel 233. Moreover, the outdoor side edge part of the plywood 243 * 243 is mounted in the support member 244 mentioned later. Thus, the counter unit 236 is disposed on the upper end of the lower wall 230 through the plywood 243 and 243. The upper side surface of the counter unit 236 is set to be substantially the same as the reference floor surface on the first floor (see FIG. 2).

  The wiring housing portion 237 shown in FIGS. 3, 4, and 6 is a portion (space) that can accommodate piping, wiring, and the like. The wiring housing part 237 mainly includes a first housing part 246, a second housing part 247, and a third housing part 248.

  The first accommodating portion 246 is a space defined between the plywoods 243 and 243, the lower wall inner heat insulating plate member 232, the lower wall heat insulating panel 233, and the support member 244. The support member 244 is attached to the fixing member 146, a pillar (not shown) or the like (that is, the upper wall portion 130) with the upper end portion of the lower wall heat insulation panel 233 aligned with the height. The support member 244 protrudes indoors from the upper wall portion 130 above the lower wall outer heat insulating plate 231. The support member 244 is arranged away from the lower wall heat insulation panel 233 toward the outside.

  In this way, a gap is formed between the support member 244 and the lower wall heat insulation panel 233, and the plywoods 243 and 243 and the lower wall inner heat insulation plate material 232 are disposed above and below the gap, respectively. A substantially rectangular space (first housing portion 246) is formed as viewed. The first accommodating portion 246 is formed at the upper end portion of the lower wall portion 230. The 1st accommodating part 246 is formed so that it may extend along the wall surface direction (lateral direction) of the lower wall part 230 (refer FIG. 6).

  The second housing portion 247 is a space formed by dividing the lower wall inner heat insulating plate 232 in the wall surface direction (lateral direction). In other words, the second accommodating portion 247 is a space defined between the end portions of the two lower wall inner heat insulating plate members 232 in the wall surface direction and between the lower wall outer heat insulating plate member 231 and the lower wall heat insulating panel 233. . The 2nd accommodating part 247 is formed so that it may extend in an up-down direction (vertical direction).

The floor finishing material 124 is supported from below by the discarding 123. The outdoor side end of the floor finish 124 is in contact with the heater panel 234 of the lower wall 230.

  The airtight sheet 60 shown in FIGS. 3 to 5 is made of a material having moderate elasticity such as synthetic resin or synthetic rubber. The airtight sheet 60 is disposed so as to cover the entire house 1 except for the floor portions (the general floor portion 10 and the low floor portion 20). For example, in the outdoor side wall portion 30 (the lower wall portion 230 and the upper wall portion 130), the airtight sheet 60 is disposed along the wall body in the wall body of the outdoor side wall portion 30. In the drawings, the airtight sheet 60 is shown by a thick black broken line for convenience.

  Specifically, the airtight sheet 60 is disposed in the lower wall portion 230 of the outdoor side wall portion 30 from between the lower wall heat insulation panel 233 and the heater panel 234 to between the plywoods 243 and 243. Further, the airtight sheet 60 is disposed between the upper wall inner heat insulation panel 135 and the upper wall interior material 136 in the upper wall portion 130 of the outdoor side wall portion 30. With such an arrangement, the airtight sheet 60 can easily form an airtight line along the shape of the outdoor side wall portion 30 (a shape having a step).

  Below, the structure of the heater panel 234 is demonstrated in detail using FIG.7 and FIG.8.

  The heater panel 234 is configured to generate heat as described above. The heater panel 234 mainly includes a heater 310, a first pressing plate 320, and a second pressing plate 330.

  The heater 310 is formed in a flexible sheet shape. The heater 310 is formed in a substantially rectangular shape extending in the left-right direction when viewed from the front. The heater 310 mainly includes a thin film heating element 311 (shaded portion in the drawing), a thin film electrode (not shown), and an electric wire 312 connected to the electrode. The heating element 311 is disposed facing forward. The electric wire 312 is accommodated in a wiring accommodating portion 237 formed in the lower wall portion 230 of the outdoor side wall portion 30 and connected to a power source in the house 1. Thus, when the electrode is energized through the electric wire 312, the heating element 311 generates heat (the heater 310 generates heat). As such a heater 310, for example, a PTC (Positive Temperature Coefficient) heater is employed.

  The first pressing plate 320 is a plate-like member. The first pressing plate 320 is formed in a substantially rectangular shape extending in the left-right direction when viewed from the front. Specifically, the first pressing plate 320 is formed slightly longer in the left-right direction than the heater 310. The first pressing plate 320 includes a first opening 321 that is rectangular in a front view on the left side.

  The second pressing plate 330 is a plate-like member. The second pressing plate 330 is formed in a substantially rectangular shape extending in the left-right direction when viewed from the front. Specifically, the second pressing plate 330 is formed to have substantially the same shape and size as the first pressing plate 320. The second pressing plate 330 includes a second opening 331 having a rectangular shape in front view on the left side.

  Thus, the heater panel 234 is formed by assembling the heater 310, the first pressing plate 320, and the second pressing plate 330 together. Specifically, the first presser plate 320 and the second presser plate 330 are respectively arranged in front and rear of the heater 310, and the heater 310 is sandwiched by the first presser plate 320 and the second presser plate 330 from the front-rear direction. . Accordingly, the heater panel 234 is formed so that the heating element 311 of the heater 310 contacts the first pressing plate 320. Moreover, the 1st opening part 321 of the 1st press board 320, the electric wire 312 of the heater 310, and the 2nd opening part 331 of the 2nd press board 330 are arrange | positioned in the position which opposes the front-back direction. Thereby, the electric wire 312 of the heater 310 can be taken out to the front or rear of the heater panel 234 via the first opening 321 and the second opening 331.

  In the heater panel 234 having such a configuration, when the heater 310 generates heat, the first pressing plate 320 is heated. Thus, forward radiant heat (far infrared rays) is emitted from the surface of the heated first pressing plate 320.

  Further, when the heater panel 234 provided on the lower wall portion 230 generates heat, radiant heat (far infrared rays) is emitted toward the living room 21 through the lower wall interior material 235 disposed on the indoor side of the heater panel 234. (See FIG. 10).

  Below, the wiring (accommodating) operation | work of the electric wire 312 when the heater panel 234 is installed in the lower wall part 230 is demonstrated using FIG.

  In the present embodiment, the three heater panels 234 are arranged on the lower wall portion 230 so as to be adjacent to each other along the wall surface (see FIG. 6). In addition, lower wall interior materials 235 are disposed indoors of the three heater panels 234, respectively. After the heater panel 234 is installed on the lower wall portion 230, the electric wire 312 is accommodated in the wiring accommodating portion 237 and connected to the power source in the house 1.

  Specifically, when the heater panel 234 is installed, the counter unit 236 and the plywoods 243 and 243 of the lower wall unit 230 are removed from the lower wall unit 230. Thus, in a state where the counter unit 236 is removed from the lower wall part 230, the upper side of the lower wall part 230 (that is, the upper end surface of the lower wall part 230) is the first accommodating part 246, the second accommodating part 247, The three accommodating portions 248 are sequentially communicated with the second opening 331 of the second pressing plate 330 of the heater panel 234. That is, in a state where the counter unit 236 is detached from the lower wall unit 230, the wiring housing unit 237 is opened upward. Thus, in the present embodiment, the wiring housing portion 237 is configured to be openable upward.

  That is, the electric wire 312 of the heater panel 234 extends from the second opening 331, and the third storage portion 248 and the second storage portion 247 are sequentially stored, and is taken out above the lower wall portion 230. The electric wire 312 taken out above the lower wall portion 230 can be arranged along the first housing portion 246 from above and can be extended toward the power supply side in the house 1. As described above, the electric wire 312 of the heater panel 234 is accommodated in the wiring accommodating portion 237 and extended toward the power source side in the house 1 and then connected to the power source.

  Thus, when the electric wire 312 of the heater panel 234 is connected to the power source in the house 1, the counter unit 236 and the plywoods 243 and 243 are attached to the lower wall unit 230. That is, the wiring accommodating portion 237 is covered from above by the counter portion 236 and the plywoods 243 and 243. Thereby, the wiring work of the electric wire 312 when the heater panel 234 is installed is completed.

  Thus, in wiring work of the electric wire 312 when the heater panel 234 is installed, the counter portion 236 and the plywoods 243 and 243 are detached from the lower wall portion 230, so that the electric wire 312 is housed from above the lower wall portion 230. 1 can be easily connected to the power source in the system. Moreover, since the electric wire 312 can be accommodated in the wiring accommodating part 237 from the upper part of the lower wall part 230, the wiring (accommodating) operation | work of the electric wire 312 can be performed easily.

  In this embodiment, when the heater panel 234 is installed, the counter unit 236 and the plywood 243 and 243 are removed from the lower wall unit 230. However, the wiring work of the electric wire 312 is limited to this procedure. It is not a thing. Specifically, after the heater panel 234 is installed, the counter unit 236 and the plywoods 243 and 243 may be attached to the lower wall unit 230. According to such a configuration, when the wiring work of the electric wire 312 is performed, the trouble of removing the counter unit 236 and the plywood 243 and 243 (once attached) is not required, so that the efficiency of the wiring work of the electric wire 312 is improved.
