Hereinafter, an embodiment of a house structure of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic explanatory view showing a first embodiment of the present invention. In the figure, 1 is a foundation, 2 is an outer wall, and an underfloor space 4 is provided in an area sandwiched between a floor 3 (a floor formed by flooring) and the foundation 1, and a plurality of ( Three rooms A, B, and C are formed in the illustrated example. In addition, a heat insulating material 6 is laid on the upper surface of the bottom of the underfloor space 4, and the heat insulating material 6 is attached to the inner surface of the side portion, and the entire living space is surrounded by the heat insulating material 7. In addition, the ceiling material of each room A, B, C, the support structure of the floor material in the floor part 3, the roof, etc. are not illustrated.
Reference numeral 8 denotes an air conditioner, which includes an outdoor unit 8A installed outside the building and an indoor unit 8B attached inside the building. In this case, the indoor unit 8B is attached to a corner portion of the underfloor space 4 and includes a blowout port 9 for blowing warm air or cold air into the underfloor space 4 and a suction port 10 for sucking air from the indoor side. Reference numeral 11 denotes a controller of the air conditioner 8, and in this case, is attached to the inner wall (not shown) surface in the room A.

  The floor 3 is provided with one or more flow control ports 12. In the example shown in the figure, one flow adjusting port 12 is provided in the floor material portion of the room C at the corner opposite to the indoor unit 8B in the underfloor space 4, but the present invention is not limited to this. The flow adjusting port 12 moves a part of the warm air or cold air in the underfloor space 4 to the indoor side (here, the room C), thereby causing the warm air or cold air in the underfloor space 4 to flow and causing the underfloor space 4 to flow. It is intended to make it fully reach the corners. Thereby, the temperature of the underfloor space 4 can be made substantially uniform. In some cases, the flow adjustment port 12 is not provided.

  Moreover, it is preferable that the flow adjusting port 12 is provided with an opening / closing member for adjusting the flow rate of warm air or cold air. As this opening / closing member, for example, as shown in FIG. 2, an opening / closing member 13 comprising a frame body 13a and a plurality of louver plates 13b rotatably arranged inside the frame body 13a can be used. It is not limited to. The opening / closing member 13 can freely adjust the opening area of the frame 13a within the range of fully closed to fully open by changing the opening angle of the plurality of louver plates 13b. As a result, the flow rate of warm air or cold air passing through the flow control port 12 can be adjusted.

  As the opening / closing member, for example, as shown in FIG. 3, an opening / closing member 14 comprising a fixed disk 14a and a rotating disk 14b pivotally supported coaxially with the fixed disk 14a can be used. The opening / closing member 14 has a plurality of fan-shaped holes 14d formed in the circumferential direction of the upper rotating disk 14b with respect to the fan-shaped holes 14c formed in the circumferential direction of the lower fixed disk 14a. By changing the position, the fan-shaped hole 14c of the fixed disk 14a can be freely adjusted within the range of fully closed to fully open. As a result, the flow rate of warm air or cold air passing through the flow control port 12 can be adjusted.

  In the first embodiment configured as described above, when the air conditioner 8 is operated by the controller 11, for example, warm air is blown into the underfloor space 4 from the outlet 9 of the indoor unit 8B in the heating mode. At this time, a desired heating temperature can be set by the controller 11.

  Due to the warm air blown into the underfloor space 4, the inside of the underfloor space 4 is gradually heated and the temperature rises, and the heat is transferred to the floor portion 3 to raise the temperature of the floor portion 3. For example, when the opening / closing member 13 is slightly opened after the floor portion 3 is sufficiently warmed, a part of the warm air in the underfloor space 4 flows to the room C side through the flow adjusting port 12. For this reason, the flow is gently generated in the underfloor space 4 and the warm air sufficiently reaches the corners in the underfloor space 4. Thereby, the temperature in the underfloor space 4 can be made substantially uniform. The opening / closing member 13 may be opened on the downstream side before blowing warm air into the underfloor space 4 and may be opened appropriately in the middle.

  The floor 3 heated by the warm air in the underfloor space 4 radiates or convects the heat to warm the rooms A, B, and C. As described above, the temperature in the underfloor space 4 is kept substantially uniform by the flow of warm air, so that the amount of radiant or convective heat from the floor 3 becomes substantially equal over the entire surface.

  The warm air that has flowed to the room C side through the flow adjusting port 12 flows into the adjacent room B through the gaps such as under the door, the louver, and the space, without remaining in the room C, and further It also flows into the next room A. For this reason, some warm air which moved from underfloor space 4 flows through each room A, B, and C sequentially. In room A, warm air is sucked into the suction port 10. As a result, the warm air in the underfloor space 4 circulates while flowing in each room, and the warm air blowout from the indoor unit 8B to the underfloor space 4 becomes smooth.

  The warm air flowing through each room A, B, and C is at a very slow speed and does not feel the wind on the skin, so it is forcibly blown out by a fan from an indoor unit attached to each room as in the past. It is different from warm air.

  The floors of the rooms A, B, and C can also have the effect of floor heating. For this reason, since it is not necessary to install a floor heating apparatus, the capital investment can be reduced and the running cost can be reduced. Moreover, since it is warm from the bottom, sufficiently satisfactory heating can be obtained even if the set temperature of the air conditioner 8 is low, which can contribute to energy saving.

  The inefficiency at the time of heating in the conventional method is that a temperature difference of about 3 ° C. to 5 ° C. occurs between the floor and the ceiling. However, according to the present embodiment, the temperature difference between the vicinity of the floor and the ceiling is less than 1 ° C., and it has been found that the heating efficiency is very excellent. Moreover, the ceiling height of the building at this time was higher than usual, and there was no ceiling fan on the ceiling.

  The above is the description for the case of the heating mode, but it can be carried out in the same manner also in the case of the cooling mode.

  Next, another embodiment of the air conditioner of the present invention will be described with reference to the accompanying drawings. FIG. 4 is a schematic explanatory view showing a second embodiment of the present invention. In the figure, 21 is an underfloor space on the first floor in a detached building (two floors), and is a region sandwiched between a floor 22 (specifically, a floor formed by flooring) and a foundation 23 as described above. A heat insulating material 24 is laid on the upper surface of the foundation 23 below the region.

A plurality of flow adjustment ports 25 are provided at the important points of the floor portion 22, and although not shown, the opening / closing members 13 (or the opening / closing members 14) are respectively attached to the flow adjustment ports 25. A plurality (three in the illustrated example) of rooms D, E, and F are formed by the inner wall 26 or the partition. Note that a heat insulating material (not shown) is attached to the inside of the outer wall 27 in the same manner as described above. Reference numeral 28 denotes a ceiling material on the first floor.
Insulating material 31 is laid.

  Reference numeral 29 denotes an underfloor space on the second floor, which is formed by a region sandwiched between a floor portion 30 (a floor formed by stretching a flooring material) and the ceiling material 28 on the first floor, and a ceiling on the first floor below the region. A heat insulating material 31 is laid on the back. 4 and 5, the structures of the floor portions 22 and 30 are shown in detail. If the floor portion 22 on the first floor shown in FIG. A moisture-proof / waterproof material 22c such as a waterproof paint, film, or sheet made of water-resistant veneer or polyolefin resin is interposed between the portion 22b and the entire bottom surface of the flooring. The moisture-proof / waterproof material 22c is not limited to the space between the floor material 22a and the floor material support portion 22b, and may be provided on the lower surface of the floor material support portion.

  The floor material 30 on the second floor is also provided with a plurality of flow adjusting ports 32 at important points, and although not shown, the opening / closing member 13 (or the opening / closing member 14) is attached to each of the flow adjusting ports 32. Yes. A plurality (three in the illustrated example) of rooms G, H, and I are formed by the inner wall 33 or the partition.

  Reference numeral 34 denotes an air conditioner, which includes an outdoor unit 34A and an indoor unit 34B. The indoor unit 34B includes an air outlet 35 that blows out warm air or cold air, and a suction port 36 that sucks air from the indoor side. And the warm air or cold air blown from the blower outlet 35 of the indoor unit 34B is blown into the first floor underfloor space 21 and the second floor underfloor space 29 by an air supply path 37 provided in the building. In this case, a controller for controlling the air conditioner 34 is not shown. The air supply path 37 can use a space formed in stairs.

  Reference numeral 38 denotes a flow dividing means, which is provided at a lower end portion in the air supply passage 37 and is opposed to the blowout port 35. As the diversion means 38, for example, a switching valve can be used as shown in FIG. 5, but it is not limited to this. In this case, when the flow dividing means 38 is switched to the position of the solid line, the warm air or the cold air blown from the air outlet 35 can be guided and blown into the underfloor space 21 on the first floor, and at the position of the virtual line (two-dot chain line). By switching, warm air or cold air blown out from the air outlet 35 can be guided to the air supply path 37 and blown into the second floor space 29 on the second floor. Further, when the flow dividing means 38 is switched to a region between the position of the solid line and the position of the imaginary line, the warm air or the cold air blown out from the air outlet 35 is supplied to both the first floor underfloor space 21 and the second floor underfloor space 29. It is possible to blow separately, and the ratio of the blow amount can be changed. Reference numeral 39 denotes control means for switching the diversion means 38.

  4 and 5, reference numeral 40 denotes a ventilation path provided inside the building, the lower end communicates with the air inlet 36 of the indoor unit 34B, and the upper end opens into the room G on the second floor. 40a is provided. 41 is a ceiling material on the second floor.

  In the second embodiment configured as described above, when the air conditioner 34 is operated by a controller (not shown), for example, in the heating mode, warm air is blown into the underfloor space 21 on the first floor from the outlet 35 of the indoor unit 34B. . At this time, the flow dividing means 38 is switched to the position of the solid line. In the heating mode, a desired heating temperature can be set in the controller.

  The warm air blown into the underfloor space 21 on the first floor gradually heats the air in the underfloor space 21 on the first floor, and the temperature rises, and heat is transferred to the flooring 22 to increase the temperature of the flooring 22. Let When the opening / closing member 13 (or the opening / closing member 14) is appropriately opened, part of the warm air in the underfloor space 21 on the first floor flows through the flow adjusting ports 25 and flows into the rooms D, E, and F, respectively. For this reason, the warm air flows gently in the underfloor space 21 on the first floor, and the warm air sufficiently reaches the corners in the underfloor space 21 on the first floor. Thereby, the temperature in the underfloor space 21 on the first floor can be made substantially uniform.

  The floor 22 heated by the warm air in the underfloor space 21 on the first floor radiates, conducts, and convects the heat to warm the rooms D, E, and F. As described above, the temperature in the underfloor space 21 on the first floor is kept substantially uniform by the flow of warm air, so the amount of heat radiated or convected from the entire surface of the floor portion 22 becomes substantially equal. Thereby, nonuniformity does not arise in the amount of heat to each room D, E, and F.

  The warm air that has flowed to the room side through the flow adjusting port 25 flows into the adjacent room through the gaps such as under the doors, louvers, and columns, without staying in each room, and further, corridors, stairs, etc. Move to. A part of the warm air moves to the second floor through a space such as a staircase, and the living space on the second floor is heated to some extent and then flows into the ventilation path 40 from the inlet 40a. The warm air flowing into the ventilation path 40 is sucked into the indoor unit 34B from the suction port 36. In this way, the warm air in the first floor underfloor space 21 and the second floor underfloor space 29 circulates while flowing through the first floor and second floor living spaces, and therefore, the indoor unit 34B transfers to the first floor underfloor space 21. Warm air blows out smoothly.

  In particular, when it is desired to heat the second floor, the flow dividing means 38 is switched to a virtual line position. Thereby, the warm air blown out from the indoor unit 34B outlet 35 flows into the air supply path 37 side without going to the underfloor space 21 side on the first floor, and is guided by the air supply path 37 to be underfloor on the second floor. It is blown into the space 29.

  Due to the warm air blown into the second floor underfloor space 29, the air in the second floor underfloor space 29 is gradually heated and the temperature rises, and heat is transferred to the floor 30 to raise the temperature of the floor 30. Let At this time, when the opening / closing member 13 (or the opening / closing member 14) is slightly opened, part of the warm air in the underfloor space 29 on the second floor flows through the flow adjustment port 32 and flows into the rooms G, H, and I, respectively. . For this reason, the warm air flows gently in the second floor underfloor space 29, and the warm air sufficiently reaches the corners. Thereby, the temperature in the underfloor space 29 on the second floor can be made substantially uniform.

  The floor 30 heated by the warm air in the second floor underfloor space 29 radiates and convects the heat to warm the rooms G, H, and I. As described above, the temperature in the second floor underfloor space 29 is kept substantially uniform by the flow of warm air, so that the amount of heat radiated or convected from the entire surface of the floor 30 is substantially uniform. Thereby, nonuniformity does not arise in the amount of heat to each room G, H, and I.

  The warm air that has flowed to the room side through the flow adjusting port 32 flows into the adjacent room through a gap such as under the door, a louver, or a space, for example, without staying in each room. And after heating each room, it flows in into the ventilation path 40 from the said inflow port 40a, and is attracted | sucked by the indoor unit 34B from the said suction inlet 36. FIG. In this way, the warm air in the second floor underfloor space 29 circulates while flowing through the second floor living space, so that warm air is smoothly blown from the indoor unit 34B to the second floor underfloor space 29.

  On the other hand, when it is desired to heat the first floor and the second floor at the same time, the flow dividing means 38 is switched to an intermediate position between the position of the solid line and the position of the virtual line. Thereby, the warm air blown out from the outlet 35 of the indoor unit 34B is divided into one that flows to the underfloor space 21 side of the first floor and one that flows to the underfloor space 29 side of the second floor via the air supply path 37. The At this time, by changing the switching position of the flow dividing means 38, the ratio between the flow rate to the underfloor space 21 side of the first floor and the flow rate to the underfloor space 29 side of the second floor can be finely adjusted.

  The above is the description for the case of the heating mode, but it can be carried out in the same manner also in the case of the cooling mode. Moreover, although said 2nd embodiment is a case of 2 stories, this invention is not limited to it, It is possible to apply also to the building more than 3 stories.

  In the case of a building having three or more floors, although not shown, a flow dividing means is provided in an air supply path communicating from the first floor underfloor space to the nth floor (n ≧ 2) underfloor space. It is configured so that warm air or cold air can be sent to the under floor space of any floor up to the floor. With such a configuration, even a building such as a building can be applied sufficiently regardless of the number of floors.

  According to the present invention, a plurality of rooms can be efficiently cooled and heated by at least one air conditioner. A central type air conditioning system can be realized with a facility cost of about 20% compared to the conventional system. In the conventional air conditioning system, an air conditioner is attached to each room and air conditioning is performed by forced air blowing into the living space. However, depending on the room or a place inside the room, the air conditioning effect is uneven and the efficiency is low. In contrast, in the air conditioner of the present invention, a single air conditioner is used to efficiently use a plurality of rooms by utilizing heat conduction to the flooring, radiation from the flooring, and convection heat. It can be air-conditioned.

  INDUSTRIAL APPLICABILITY The present invention can be effectively used as an air conditioner that can efficiently cool and heat all rooms in a building by using at least one air conditioner.
