Description

[Technical Field]

[0001] The present invention relates to an air conditioning structure for a building. [Background technology]

[0002] In buildings such as houses, systems have been developed that include deodorizing equipment in living rooms (see, for example, Patent Document 1). This deodorizing equipment provides a dedicated ventilation space for deodorizing the living room, and a fan and a deodorizing sheet are installed in this ventilation space. In this deodorizing equipment, (a portion of) the air in the living room is guided into the ventilation space by the fan, and the air guided into the ventilation space is passed through a deodorizing sheet, where it is deodorized, and then returned to the living room. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-325617 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the deodorizing equipment for a building disclosed in Patent Document 1, the ventilation space was large and circularly installed in the attic (above the ceiling) of the room, running around the wall of the room. This made the deodorizing equipment large-scale. Furthermore, the deodorizing equipment was installed as a standalone unit for only one room. Therefore, the deodorizing equipment did not take into consideration the entire building, other rooms, or other equipment in the room, such as air conditioning equipment.

[0005] Therefore, a main object of the present invention is to contribute to improving the above-mentioned problems. [Means for solving the problem]

[0006] In response to the above problems, the present invention provides: An air conditioning structure for a building having a common space and a large room and individual rooms adjacent to the common space, An air conditioner is installed under the floor of the large living room, and an air purifier is embedded in the ceiling of the large living room, The clean air purified by the air purifier in the large living room is taken into the common space through a gap under the door and window as a clean air intake. 、 The large room is provided with an air conditioning outlet and an air conditioning inlet of the air conditioner at room ends diagonally positioned under the floor of the large room, The air purifier has an intake section on the side of the air conditioning outlet and an outlet section on the side of the air conditioning intake. The building's air conditioning structure is a distinctive feature. [Effects of the Invention]

[0007] According to the present invention, the above configuration makes it possible to install an air purifier in a large room without making it too large, while still being able to distribute the clean air from the large room to common spaces. In addition, in large rooms, the air conditioner's air outlet and air intake are located at the end of the room diagonally opposite the large room under the floor, so that the air conditioning outlet and air intake are installed at the farthest positions in the large room, creating a larger circulation of air conditioning air across the floor and ceiling throughout the large room, improving the air conditioning efficiency of the air conditioner and the purification efficiency of the air purifier. Furthermore, by having an intake section on the side of the air conditioning outlet and an exhaust section on the side of the air conditioning inlet, the air purifier makes it easier to draw in conditioned air from the air conditioning outlet of the air conditioner and to send the conditioned air purified by the air purifier to the air conditioning inlet of the air conditioner, thereby arranging the conditioned airflow circulated within a large living room into the most efficient path, creating a more efficient conditioned airflow, and further improving the air conditioning efficiency of the air conditioner and the purification efficiency of the air purifier.

[0009] Hereinafter, this embodiment will be described in detail with reference to the drawings. 1 to 6 are used to explain this embodiment. [Example]

[0010] <Configuration> The configuration of this embodiment will now be described.

[0011] As shown in the vertical cross section of FIG. 1, an air conditioner 2 is installed in a building 1 such as a house.

[0012] The main body of the building 1 is placed on a foundation 4 constructed on a site 3. The building 1 may be a single-story building, or may be a multi-story building with two or more floors. In this embodiment, the building 1 is two-story. The building 1 has one or more large living rooms 5 and individual living rooms 6 inside, as well as a common space 8 with an open ceiling shape that extends from the lower floor to the upper floor. The large living room 5 and the individual living rooms 6 are each adjacent to the common space 8 via a wall 9 (partition). However, the internal configuration of the building 1 is not limited to the above.

[0013] In addition to the basic configuration described above, the following configurations can be provided.

[0014] (A) The air conditioning structure of Building 1 is as follows: An air conditioner 2 is installed under the floor 11 of the large living room 5, and an air purifier 13 is buried in the ceiling 12 of the large living room 5.

[0015] Here, the air conditioning structure of the building 1 refers to the equipment and structure for creating a required air conditioning environment within the building 1.

[0016] The large room 5 is preferably the largest room in the building 1 or a room of similar size (for example, the second or third largest room). The large room 5 is preferably at least 9 tatami mats in size, but may be smaller than 9 tatami mats depending on the conditions of the building 1. The large room 5 is equipped with both an air conditioner 2 and an air purifier 13. Note that a relatively large room (compared to other rooms) in the building 1 can also be treated as a large room 5 as long as it is equipped with both an air conditioner 2 and an air purifier 13. The number of large rooms 5 is not limited to one.

[0017] In this embodiment, the large living room 5 equipped with the air conditioner 2 and air purifier 13 is the largest space in the building 1 and is likely to be used by all residents as a living room, shared living room, or living-dining room or living-dining-kitchen room on the lower floor. The following description will be given assuming an air conditioning structure centered on the large living room 5 on the lower floor. However, the large living room 5 may also be located on an upper floor, in which case both the air conditioner 2 and the air purifier 13 are installed in the large living room 5 on the upper floor.

[0018] The individual rooms 6 are, for example, private rooms used by each resident. The common spaces 8 are common spaces such as entrance halls, stairs, and corridors through which residents temporarily pass to access the large rooms 5 and the individual rooms 6.

[0019] The underfloor space 11 is a space formed below the floor surface 15 of the lower floor. The underfloor space 11 of the large living room 5 on the lower floor is the internal space of the foundation 4. The foundation 4 may be a strip foundation mainly composed of a rising portion, or may be a mat foundation composed of a rising portion and a slab portion that covers the ground inside the rising portion.

[0020] Air conditioner 2 is an air conditioning device that adjusts the temperature inside large living room 5 to create an air-conditioned environment (temperature, humidity, etc.) inside large living room 5. The air conditioner 2 shown in the figure is an indoor unit and is installed in the interior space of foundation 4. This indoor unit (air conditioner 2) is installed on the ground or on a slab inside foundation 4. The outdoor unit (not shown) of air conditioner 2 is installed in a part of site 3 near building 1 (outside building 1), for example.

[0021] The ceiling 12 is a surface that forms the upper part of the large living room 5. In this embodiment, the air purifier 13 is embedded in the ceiling 12 of the lower floor.

[0022] In order to install air purifier 13 in an embedded state, an opening 16 of a size and shape capable of accommodating air purifier 13 is formed in ceiling 12 of the lower floor, as shown in Figure 2. Air purifier 13 is installed through opening 16 in space 18 between ceiling 12 of the lower floor and floor surface 17 of the upper floor, with its underside approximately flush with ceiling 12.

[0023] An enclosure 19 that covers the opening 16 from above may be provided in the space 18 between the ceiling 12 of the lower floor and the floor surface 17 of the upper floor, and this enclosure 19 may be used as a storage section for storing the air purifier 13. The storage section is a substantially box-shaped body that is about one size larger than the air purifier 13, and a mounting member 19a that closes the opening 16 is attached to the underside of the box-shaped body with the air purifier 13 positioned therethrough.

[0024] In addition, when configuring the air conditioning structure for the large living room 5 on the upper floor, the air conditioner 2 is installed in the space 18 between the floor surface 17 of the upper floor and the ceiling 12 of the lower floor (either under the floor of the upper floor or in the storage space of the common space 8 on the upper floor), and the air purifier 13 is installed in the ceiling of the upper floor or in the lowered ceiling space by lowering part of the ceiling surface. The same interpretation shall be applied to the following items.

[0025] The air purifier 13 is a device that purifies the air by removing fine particles, dust, etc. The air purifier 13 may also have a deodorizing function that decomposes, adsorbs, and removes odorous components.

[0026] (B) As shown in FIG. 1, the air purifier 13 may be installed under the floor 11, midway between the air conditioning outlet 21 and the air conditioning inlet 22 (for the large room 5).

[0027] Here, air conditioning outlet 21 is an opening for blowing conditioned air 23 from air conditioner 2 under floor 11 into large living room 5. Air conditioning outlet 21 is formed so as to penetrate vertically through floor surface 15 of large living room 5 on the lower floor. Air conditioning outlet 21 and air conditioner 2 are connected by outlet duct 24.

[0028] Air conditioning intake 22 is an opening for drawing air from inside large living room 5 and air conditioning airflow 23 into air conditioner 2 under floor 11. Air conditioning intake 22 is formed in floor surface 15 of large living room 5 on the lower floor, penetrating vertically. Air conditioning intake 22 and air conditioner 2 are connected by intake duct 25.

[0029] In this embodiment, another air conditioning intake 26 is also formed on the floor 28 of the common space 8, such as the entrance hall. Another intake duct 27 can connect the other air conditioning intake 26 to the air conditioner 2. This allows air from the common space 8 to also be drawn into the air conditioner 2.

[0030] The intermediate portion between the air conditioning outlet 21 and the air conditioning inlet 22 refers to the portion of the ceiling 12 between the position directly above the air conditioning outlet 21 and the position directly above the air conditioning inlet 22.

[0031] The intermediate portion is any position on the line segment that linearly connects the position directly above the air conditioning outlet 21 and the position directly above the air conditioning inlet 22, excluding both ends of the line segment. Air purifier 13 may be installed on the line segment. Installing on the line segment means that air purifier 13 is installed so that a part of it overlaps the line segment in a plan view, and it is preferable that air purifier 13 is installed so that its center substantially overlaps the line segment.

[0032] Furthermore, it is most preferable that the air purifier 13 is installed so that the center of the air purifier 13 is approximately aligned with the center of the above-mentioned line segment. However, the center of the air purifier 13 may be slightly deviated from or shifted from the above-mentioned line segment.

[0033] (C) The air purifier 13 may have an intake section 31 on the air conditioning outlet 21 side and an outlet section 32 on the air conditioning inlet 22 side.

[0034] Here, suction section 31 refers to an opening provided in air purifier 13 for drawing air into the interior of air purifier 13. As shown in FIG. 3, suction section 31 is provided in approximately half of one side of the underside of air purifier 13. Air purifier 13 has an openable front panel 34 on its underside. As shown in FIG. 4, suction section 31 is formed in a portion on the side of hinge section 35 that opens and closes front panel 34. A number of suction holes 36 are formed in the portion of front panel 34 that covers suction section 31, and pre-filters 37 or the like may be installed in suction holes 36.

[0035] The blow-out section 32 is an opening provided in the air purifier 13 for blowing out air from the air purifier 13. The blow-out section 32 is provided in approximately half of the area on the underside of the air purifier 13 opposite the suction section 31. The blow-out section 32 is formed in the part opposite the hinge section 35.

[0036] Air purifier 13 is installed on ceiling 12 with its circumferential orientation adjusted so that air inlet 31 is closer to air conditioning outlet 21 than air outlet 32, and air outlet 32 ​​is closer to air conditioning inlet 22 than air inlet 31. This makes the linear distance between air inlet 31 and air conditioning outlet 21 shorter than the linear distance between air outlet 32 ​​and air conditioning outlet 21. Also, the linear distance between air outlet 32 ​​and air conditioning inlet 22 is shorter than the linear distance between air inlet 31 and air conditioning inlet 22.

[0037] As shown in FIG. 4, the air purifier 13 is equipped with a filter set 41 equipped with various filters, such as a dust collection filter for removing fine particles and a deodorizing filter for deodorizing. The filter set 41 is in the form of a cartridge and is installed in the air purifier 13 so that it can be detached and replaced. When the filter set 41 deteriorates after a certain period of use, the cartridge is used as is, but the dust collection filter and deodorizing filter are replaced with new ones. In this embodiment, the filter set 41 is provided on the suction unit 31 side of the air purifier 13. The cartridge is replaced from the bottom by opening the front panel 34 described above.

[0038] As shown in FIG. 5, air purifier 13 includes at least a circulation fan 42 and a motor 43 that drives circulation fan 42 to rotate, in addition to filter set 41.

[0039] By rotating the circulation fan 42 using the motor 43, the circulation fan 42 draws in air (or conditioned air 23) from the suction section 31 and blows out purified air (or conditioned air 23) from the blowing section 32.

[0040] In this case, filter set 41 is installed at an appropriate position between suction section 31 and blow section 32, and air (or conditioned air 23) forcibly sucked in from suction section 31 by circulation fan 42 is passed through the interior and purified by the filters. The air (or conditioned air 23) purified by filter set 41 is sent out to blow section 32.

[0041] Furthermore, air purifier 13 may be internally provided with an ion generator 44 that generates ionized particles such as OH radicals. This ion generator 44 can decompose and remove odorous components in the air and sterilize the air. Note that the arrangement of filter set 41, circulation fan 42, and ion generator 44 relative to air purifier 13 is not limited to the above.

[0042] (D) As shown in FIG. 6, the air conditioning outlet 21 and the air conditioning inlet 22 may be provided at a room end 52 located on a diagonal line 51 of the large room 5.

[0043] Here, diagonal line 51 is a line connecting corner portions 53 located at diagonal angles of floor surface 15 of large living room 5, which is approximately rectangular. In the case of floor surface 15 of large living room 5, which is approximately rectangular, there are two diagonal lines 51, but either one may be used.

[0044] The room edge 52 refers to a position on or near each side along the periphery of the floor surface 15 of the large living room 5.

[0045] Therefore, the room end 52 located on the diagonal line 51 of the large room 5 is at or near the corner 53 located at the diagonal of the floor surface 15 of the large room 5.

[0046] The building 1 has a common space 8, and a large room 5 and an individual room 6 each adjacent to the common space 8, and is provided with the following configuration as an air conditioning structure.

[0047] (1) In the case where the air conditioner 2 is installed under the floor 11 of the large living room 5 as described above and the air purifier 13 is buried in the ceiling 12 of the large living room 5, Clean air 61 purified by an air cleaner 13 in a large living room 5 is taken into a common space 8 through a gap under a fixture as a clean air intake port 62.

[0048] Here, the purified air 61 is air that has been purified (by removing fine particles, deodorizing, sterilizing, etc.) from the conditioned air 23 whose temperature has been adjusted by the air conditioner 2. The purified air intake 62 is formed by penetrating the wall 9 between the large living room 5 and the common space 8. The purified air intake 62 is provided in a position on the wall 9 below the large living room 5, but the position where the purified air intake 62 can be installed is not limited to this, and a separate intake grill or the like may also be installed in the middle or above the large living room 5. The gap under the fittings can be filled by directly utilizing an undercut on a door or the like.

[0049] (2) Furthermore, clean air 61 accumulated in the common space 8 can be taken into the individual living room 6 by using a gap under another door and window as another clean air intake 63, and a ventilation fan 65 can be installed in the individual living room 6 to exhaust air 64 from the individual living room 6 to the outside.

[0050] Here, the individual room 6 refers to all rooms, one or more, provided within the building 1, and the above configuration is adopted for at least one individual room 6. The individual room 6 may be equipped with an air conditioner (not shown). The separate purified air intake 63 is formed by penetrating the wall 9 between the common space 8 and the individual room 6. The separate purified air intake 63 is provided in a position on the wall 9 below the individual room 6, but the position where the separate purified air intake 63 can be installed is not limited to this, and a separate intake grille or the like may be installed in the middle or above the individual room 6. The gap under the separate fittings can be filled by directly utilizing an undercut, such as a door.

[0051] The air 64 in the individual living room 6 is air 64 stagnating in the individual living room 6. The ventilation fan 65 is equipped with an electric fan and is powerful enough to provide forced ventilation to create a negative pressure in the individual living room 6. The ventilation fan 65 may be one whose exhaust capacity can be adjusted in two or more stages, such as strong / weak or strong / medium / weak, or continuously.

[0052] <Effects> According to this embodiment, the following effects can be obtained.

[0053] (Effect A) In the air conditioning structure of the building 1, the large living room 5 may have the air conditioner 2 installed under the floor 11 and the air purifier 13 buried in the ceiling 12. This means that the air conditioner 2 and air purifier 13 will not be exposed inside the large living room 5, eliminating the need to reserve dedicated installation space for the air conditioner 2 and air purifier 13 within the large living room 5. Therefore, the space within the large living room 5 is not taken up by the air conditioner 2 and air purifier 13, making the large living room 5 look neater and more attractive, and allowing the large living room 5 to be used more widely.

[0054] Furthermore, by embedding air purifier 13 in ceiling 12, air purifier 13 can purify and deodorize the air in large living room 5. Furthermore, air purifier 13 can be embedded in ceiling 12 relatively easily. Therefore, air purifier 13 is easy to install, and it is possible to eliminate problems such as air purifier 13 being in the way when placed on floor 15, or difficulty in finding a place to place air purifier 13.

[0055] Then, conditioned air 23 or a portion thereof from air conditioner 2 installed under floor 11 of large living room 5 is sucked in and purified by air purifier 13 embedded in ceiling 12 of large living room 5, and sent to air conditioner 2 under floor 11 for forced circulation. This creates a large conditioned air current within large living room 5 that spans between floor 15 and ceiling 12, allowing conditioned air 23 to be distributed widely throughout large living room 5.

[0056] This improves the air conditioning efficiency of air conditioner 2. In addition, by using air purifier 13 to directly purify the conditioned airflow circulating in large room 5, the purification efficiency of air purifier 13 can be improved.

[0057] Therefore, the air purifier 13 as a deodorizing device for the large living room 5 is positioned with consideration for the air conditioner 2 that creates the air-conditioned environment for the large living room 5, and the synergistic effect of the cooperation between the air conditioner 2 and the air purifier 13 makes it possible to effectively utilize both the air conditioner 2 and the air purifier 13.

[0058] (Effect B) In the air conditioning structure of building 1, air purifier 13 may be installed under floor 11, midway between air conditioning outlet 21 and air conditioning inlet 22 of air conditioner 2. This allows air purifier 13 to be placed in an optimal position that makes it easy to draw in conditioned air 23 from air conditioner 2 and to send purified conditioned air 23 to air conditioner 2. Therefore, air conditioner 2 and air purifier 13 can efficiently create conditioned airflow that circulates within large living room 5. This further improves the air conditioning efficiency of air conditioner 2 and the purification efficiency of air purifier 13.

[0059] (Effect C) In the air conditioning structure of the building 1, the air purifier 13 may have an intake section 31 on the side of the air conditioning outlet 21 and an outlet section 32 on the side of the air conditioning inlet 22. This allows the air purifier 13 to easily draw the conditioned air 23 from the air conditioning outlet 21 of the air conditioner 2 using the intake section 31 (located near the air conditioning outlet 21). The air purifier 13 also makes it easy to send the purified conditioned air 23 from the outlet section 32 (located near the air conditioning inlet 22 of the air conditioner 2) to the air conditioning inlet 22. This allows the conditioned airflow circulated within the large living room 5 to be regulated by the most efficient route, resulting in a more efficient conditioned airflow. This further improves the air conditioning efficiency of the air conditioner 2 and the purification efficiency of the air purifier 13.

[0060] (Effect D) In ​​the air conditioning structure of the building 1, the air conditioning outlet 21 and the air conditioning inlet 22 may be provided at the room end 52 located on the diagonal line 51 of the large living room 5. This allows the air conditioning outlet 21 and the air conditioning inlet 22 to be installed at the farthest positions in the large living room 5, making it possible to maximize the airflow of the air conditioning across the floor 15 and ceiling 12 within the large living room 5. This makes it possible to create a larger circulation of the air conditioning airflow throughout the entire large living room 5. This further improves the air conditioning efficiency of the air conditioner 2 and the purification efficiency of the air purifier 13.

[0061] (Effect 1) By installing the air conditioner 2 under the floor 11 of the large living room 5 and burying the air purifier 13 in the ceiling 12 of the large living room 5, as described above, it is possible to install the air purifier 13 without making it too large for the large living room 5. Furthermore, by operating the air conditioner 2 while the air purifier 13 is running, the temperature environment in the large living room 5 can be adjusted by the air conditioner 2, while the air in the large living room 5 can be efficiently purified by the air purifier 13.

[0062] Then, by using a gap under the door and window fittings as a purified air intake 62 to take in the purified air 61 purified by the air purifier 13 in the large living room 5 into the common space 8, the purified air 61 from the large living room 5, which has been temperature-adjusted by the air conditioner 2 and purified by the air purifier 13, can be distributed from the purified air intake 62 to the common space 8.

[0063] (Effect 2) Clean air 61 accumulated in the common space 8 can be taken into the individual living room 6 by using a gap under another fixture as another clean air intake 63, and a ventilation fan 65 can be installed in the individual living room 6 to exhaust air 64 inside the individual living room 6 to the outside.

[0064] Then, by driving the ventilation fan 65 in the individual room 6 to forcibly exhaust (ventilate) the air 64 inside the individual room 6 to the outside, it is possible to create a negative pressure inside the individual room 6. Furthermore, by creating a negative pressure inside the individual room 6, clean air 61 that has accumulated in the common space 8 is forcibly taken into the individual room 6 through another clean air intake 63, so that the clean air 61 can also be distributed to the individual room 6. As a result of the above, it becomes possible to distribute the clean air 61 from the air purifier 13 throughout the building 1.

[0065] Furthermore, the individual rooms 6, which are the final stage of the flow of clean air 61, function as purified spaces independent of the large rooms 5 and the common space 8. Furthermore, because clean air 61 is taken into the individual rooms 6 from the common space 8, air 64 from the individual rooms 6 does not flow into the common space 8. Therefore, if necessary, the individual rooms 6 can be used safely as isolated spaces for home recuperation, etc. [Explanation of symbols]
