  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the interior panel 2 is provided with intake and exhaust ports 4 and 5 at both upper and lower ends of the interior panel body 3, respectively. In the interior panel body 3, a duct portion 6 is provided that forms a communication path that allows the intake and exhaust ports 4 and 5 to communicate with each other. A plurality of sirocco fans 7 a serving as air blowing means 7 are provided at the lower end portion 6 a of the duct portion 6 so as to circulate room air into the duct portion 6 so as to face the lower intake / exhaust port 4.

  As shown in FIG. 3, the duct portion 6 of the interior panel body 3 is provided with a wide humidity adjusting recess 30 and a narrow circulator recess 31 in parallel. An air purification function member (not shown) such as a deodorizing filter and a humidity control agent is accommodated and held in the wide humidity control recess 30. Two sirocco fans 7 a are arranged in parallel at the lower end of the wide humidity control recess 30, and one sirocco fan 7 a is arranged at the lower end of the narrow circulator recess 31. Thereby, the duct part 6 comes to have both an air purification function and a humidity control function. In FIG. 3, 13 is a branch air passage leading to the air layer 11 described later, 50 is an electrical wiring, and 51 is a wiring holder.

  As shown in FIG. 2, the interior panel 2 is attached to a pair of left and right vertical bars 9 attached to an existing interior wall surface 1. Note that reference numeral 80 in FIG.

  In this example, the plowing work frame 8 is composed of a pair of left and right vertical bars 9 and a plurality of upper and lower horizontal bars 10 connecting the pair of left and right vertical bars 9. The vertical beam 9 is made of, for example, wood, and the horizontal beam 10 is made of, for example, metal. The horizontal beam 10 is formed thinner than the vertical beam 9, and an air layer 11 described later is continuously formed in the vertical direction without being blocked by the horizontal beam 10.

  Next, a specific example of the pruning construction frame 8 is shown in FIG. In FIG. 4, the plurality of upper and lower horizontal rails 10 are fixed to the interior wall surface 1 with fixing tools 60 such as nails and screws. At both left and right ends of each horizontal beam 10, a mounting piece 63 is bent toward the front F, and this mounting piece 63 is fixed to the inner side surface of the vertical beam 9 with fixing tools 61 such as screws and screws. Yes. Furthermore, a locking piece 64 is bent from the tip of the mounting piece 63 in the lateral direction. This locking piece 64 is bent in parallel with the back surface of the interior panel body 3. A hooking tool (not shown) provided on both side portions not interfering with the duct portion 6 on the back surface of the interior panel main body 3 can be hooked and locked to the locking piece 64 from the front F.

  Here, the hook of the interior panel body 3 is detachably hooked and locked to the locking piece 64 in a state where the back surface of the interior panel body 3 is floated forward F from the interior wall surface 1. Thus, an air layer 11 is formed between the back surface of the interior panel 2 and the interior wall surface 1 as shown in FIG. The left and right sides of the air layer 11 are respectively closed by the pair of left and right vertical bars 9 (FIG. 2). The air layer 11 is opened only up and down, and both upper and lower ends thereof are covered with an upper lid 20 and a lower lid 19 each having a ventilation opening 12.

  In this example, the upper lid 20 is attached to the upper end portion of the interior panel body 3, and the lower lid 19 is attached to the lower end portion of the interior panel body 3. A panel upper passage 15 is formed between the upper end portion of the interior panel body 3 and the ceiling surface 18, and the room and the ventilation opening 12 of the upper lid 20 communicate with each other through the panel upper passage 15. A panel lower passage 14 is formed between the lower end portion of the interior panel body 3 and the floor surface 17, and the room and the ventilation opening 12 of the lower lid 19 communicate with each other through the panel lower passage 14.

  On the other hand, a branch air passage 13 is branched and connected in the vicinity of the upper end portion 6 b on the back surface of the duct portion 6 of the interior panel body 3. The branch air passage 13 is for guiding a part of the air flowing through the duct portion 6 into the air layer 11, and in the example shown in FIG. 1, is constituted by a slit 13a that opens upward. The blowing direction from the slit 13a into the air layer 11 is upward, thereby generating an updraft in the air layer 11, and using this updraft from the panel lower passage 14 into the air layer 11 It has a structure that sucks indoor air.

  Next, the indoor air circulation operation will be described.

  When the air blowing means 7 is driven by the operation unit 80 (FIG. 2), the indoor air is sucked into the duct unit 6 from the intake / exhaust port 4 at the lower end of the interior panel 2 as shown by the arrow A in FIG. It passes through the wetting agent and the like and is returned to the room from the intake / exhaust port 5 at the upper end of the interior panel 2. At this time, a part of the air A circulating through the duct portion 6 is branched and supplied into the air layer 11 from the slit 13 a of the branch air passage 13 provided at the upper rear end of the interior panel body 3. At this time, as the air (wind) blows upward from the slit 13a, an ascending air current is generated in the air layer 11, and thereby the inside of the air layer 11 becomes negative pressure. Using this negative pressure, the room air is sucked into the air layer 11 from the panel lower passage 14 through the ventilation opening 12 of the lower lid 19 as shown by an arrow B in a path different from the arrow A in FIG. The upper end of the layer 11 is returned to the room through the upper panel passage 15 from the vent opening 12.

  Therefore, the effect of purifying the room air and the effect of adjusting the humidity can be obtained by circulating the room air through the duct part 6 having the air purification function and the humidity control function.

  Furthermore, by circulating the room air in the air layer 11 through a different path from the duct portion 6, the surface temperature T2 (FIG. 2C) of the interior wall surface 1 behind the interior panel 2 is substantially the same as the room temperature. That is, it becomes substantially the same as the surface temperature T1 of the interior wall surface 1 exposed indoors. That is, the surface temperature T2 can be lowered to room temperature without being affected by outside air / indoor temperature conditions, humidity conditions, and heat insulation conditions. As a result, it is possible to prevent condensation, mold, mites, and the like from occurring in the duct portion 6 of the interior panel 2, the back surface side thereof, and the interior wall surface 1.

  In addition, by adopting a fusari construction method that floats from the existing interior wall surface 1 and constructs the interior panel 2, it is possible to install or replace the interior panel 2 while leaving the existing interior wall surface 1 intact during renovation. Therefore, remodeling becomes easy.

  Further, in this example, the ventilation openings 12 are provided at both the upper and lower ends of the air layer 11 and the branch air passage 13 is branched and connected in the vicinity of the upper end portion of the air layer 11. Only by flowing in the air layer 11, negative pressure is easily generated in the air layer 11. Thereby, indoor air can be circulated through the air layer 11 using negative pressure. Thus, since the indoor air can be sent to the duct part 6 and the air layer 11 of the interior panel 2 by another route using one air blowing means 7, the convection of the indoor air is promoted.

  FIG. 5 shows another embodiment of the present invention. In this example, the upper end portion of the air layer 11 is covered with the upper lid 20 having the ventilation opening 12, and the lower end portion of the air layer 11 is closed with the lower lid 19a of the sealed structure. Further, a branch air passage 13 including a slit 13 a opened upward is branched and connected in the air layer 11 in the vicinity of the lower end portion 6 a of the back surface of the duct portion 6 of the interior panel body 3. And the wind comes to flow toward the upper end from the lower end of the air layer 11 by making the blowing direction from the branch air passage 13 into the air layer 11 upward. That is, even when the lower lid 19 has a closed structure without a slit, it is possible to send wind to the lower end side of the air layer 11. As a result, similar to the embodiment of FIG. 1, the surface temperature of the interior wall surface 1 behind the interior panel 2 can be made substantially the same as the room temperature, and the effect of preventing the occurrence of condensation, mold, mites, etc. can be obtained.

  In each of the embodiments shown in FIGS. 1 and 5, the case where the air blowing means 7 is driven so that the indoor air circulates from the lower intake / exhaust port 4 to the upper intake / exhaust port 5 has been described. It is not limited. For example, the air blowing means 7 may be driven so that the room air circulates from the upper intake / exhaust port 4 toward the lower intake / exhaust port 5. In short, it suffices to circulate so that warm air stays in the upper part of the room and cold air does not stay in the lower part. This makes it possible to maintain a comfortable temperature distribution in the room, so that people in the room can spend comfortably it can.
