Description

[Detailed explanation of the invention] [Industrial application field] This invention is an individual double floor that can be installed within the double floor of a building with a double floor structure to house office equipment, etc. indoors. Regarding air conditioners.

[Conventional technology]

There are two types of air conditioning equipment: central air conditioning equipment located in the basement or rooftop of a building that provides air conditioning for the entire building, and individual air conditioning equipment that consists of a single device that has the function of air conditioning for each desired room. In addition, there are fan coil unit types that are a combination of individual types and central types, which supply cold and hot water from a central machine room.
Although there are various methods, conventional individual air conditioning methods include the following.

One method that has often been adopted is to install it on the ceiling in the corner of the room, but while this method is inexpensive and relatively easy to install, it is difficult to control the direction of air blowing out, and therefore Temperature distribution and airflow within the room tend to be uneven. Furthermore, from a design point of view, the ceiling is relatively low, which creates a feeling of oppression. Furthermore, it was difficult to accommodate layout changes when changing partitions after installing an air conditioner.

Next, there is the cassette type air conditioning system, which is a device that reduces the uneven distribution of air conditioning as described above.This is a system in which the air conditioner is half-embedded in the central ceiling of the room, and the outlet for the conditioned air is Since there are 2 to 3 directions, there is no uneven air conditioning and it is easy to install. However, since the large central part of the ceiling surface is occupied by the air conditioner, there are problems due to interference with lighting equipment. Like the conventional ceiling-mounted type, it has the disadvantage of not being compatible with partitions.

Furthermore, as a way to compensate for the above drawbacks, a method called the free cassette method is used in which indoor air conditioners are embedded in the ceiling, the air outlets are installed in the ceiling, and the air conditioners are connected with ducts. Since it is embedded in the ceiling, there are also problems such as the need for sufficient ceiling space and difficulties in maintenance such as construction and post-construction maintenance.

[Problems to be solved by the invention] However, in addition to the drawbacks of each of the above-mentioned individual air conditioners of any of these conventional methods, there are also difficulties in the construction and installation of the air conditioners. So-called maintenance, such as maintenance, inspection, and servicing, requires work at heights on the ceiling, which requires floor scaffolding for work, making it difficult to work and requiring extensive preparations for the above-mentioned maintenance, making it difficult to perform. There is a problem.

Furthermore, although it is not impossible to embed the ceiling-mounted air conditioners currently in use below the floor, all of these off-the-shelf products are of the type that is mounted on the ceiling, so all of the above maintenance, etc. must be done from below (some Since the air conditioner is installed from the side (from the side), there are problems such as the need for improvements or changes in specifications if the current air conditioner is to be installed directly under the floor. Furthermore, if a conventional air conditioner is simply embedded under the floor, it is difficult for the top surface of the air conditioner to be flush with the top surface of the double floor, and vibrations generated by the air conditioner are transmitted to the floor below. , the problem of propagation occurs not only in that room but also in other rooms.

This idea was made in view of the various problems of the conventional equipment, and it solves the above problems by configuring the top cover of the equipment to also serve as part of the double floor of the building. The purpose is to

(Means for solving the problem) This invention is a thin air conditioner that can be installed in a double floor of a building, and the top cover of the air conditioner also serves as a part of the first double floor, and The structure is such that it can be easily attached to and removed from the air conditioner, and a vibration-proof elastic body and height adjustment bolts are interposed in series between the first air conditioner and the floor below, and these allow the air conditioner to be lowered. This is a double floor air conditioner supported on the side floor.

[Effect]

This idea has the above-mentioned structure, so the top cover of the air conditioner also serves as a part of the building's double floor, improving workability, and maintenance of the equipment can be done by opening and closing the top cover, which is part of the double floor. It has become extremely easy to do this because all you have to do is do it. In addition, since the height of the air conditioner can be finely adjusted using the adjustment bolt, even if the lower floor is slightly uneven, the height of the upper cover and the double floor can be matched, making it possible to adjust the height of the double floor. The whole can be made flat. Furthermore, since the vibrations generated by the air conditioner are absorbed by the vibration-proof elastic body, the vibrations are not transmitted to other rooms as well as the room itself.

〔Example〕

This invention will be explained below based on the drawings. 1 to 5 are diagrams showing an embodiment according to the present invention.

FIG. 1 is a sectional view of a double floor of a building in which a thin air conditioner 10 according to the present invention is installed, where 1 is the concrete floor of the building and 2 is the double floor. Air conditioner 1

31 is the upper cover of the coil unit, which is installed at the same height as the double floor surface 2, and
Its upper surface has the same finish as floor surface 2.
Reference numeral 41 is a perforated plate forming a part of the floor surface 2, and is provided with a large number of holes 41a for sucking indoor air. 42 is a wire mesh attached to the bottom surface of this perforated plate 41 for collecting coarse garbage, 43 is a garbage container installed on the concrete floor 1 to catch the garbage that has passed through the wire mesh 42, and 44 is a large garbage container. This is a suction tube into which a suction hose or the like of a vacuum cleaner or the like is inserted to suck out the dust in the dust container 43.

Reference numeral 22 denotes a wire mesh for removing coarse dirt provided on the air inlet side of the blower unit 20.The air passing through this wire mesh is further filtered to remove fine dust by a filter 23, and then sent in the direction of arrow A by the blower 24. .

Reference numeral 32 denotes an air conditioning coil, which cools the air sent from the blower unit 20 to a predetermined temperature in the summer, for example, and passes it under the floor in the direction of the thick arrow by a duct connected to the blower duct flange 33, and then sends it under the floor in the direction of the thick arrow. It is designed to blow air to the outlet. 34 is a drain pan for receiving moisture that has condensed and dripped onto the coil 32, and is discharged to the outside of the system through piping (not shown).

FIG. 4 is a plan view of the air conditioner 10, and each of the upper covers 21 and 31 is removably attached to the air conditioner 10 with a plurality of screws 3. The upper cover, which requires relatively frequent maintenance, may be attached with a hinge or the like that can be opened and closed, rather than with screws as in this embodiment. In addition, the sizes of these upper covers 21 and 31 are not necessarily as shown in the drawings, and they may be divided into each space such as the blower space 20a, filter space 23a, coil space 30a, electrical space 20b, piping space 30b, etc., or they may be shared. Spaces for which it is more convenient to do so may be configured as a common top cover that can be opened and closed or detached in the same way.

Reference numeral 4 denotes a vibration-proof mount interposed between the two to prevent vibrations generated from the air conditioner 10 from being transmitted to the concrete floor 1, and its details are as shown in FIG. 4a is a vibration-proof rubber consisting of three layers,
The top and bottom are clamped by steel plates 5. Numeral 6 is a bolt, which is fixed to a base plate 7 fixed to the concrete floor 1 by an anchor bolt or the like, and is screwed into a nut 8 fixed to the lower steel plate 5.

Further, the total length of the bolts 52 is set so that when the upper cover of the air conditioner 10 is parallel to the double floor surface 2, the bottom of the air conditioner 10 maintains a distance from the concrete floor 1.

It should be noted that the means for adjusting the height of the air conditioner is not limited to the means using bolts as shown in the above embodiment, but it goes without saying that means using known equipment using fluid pressure etc. may be used. do not have.

[Effect of idea]

As explained above, according to the present invention, the top cover of the air conditioner also serves as a part of the double floor of the building, making it possible to install the air conditioner from above the double floor, making construction easier. In addition, since the top cover is removable, it can be opened for maintenance and inspection, making maintenance easier as there is no need to crawl under the floor. It also has the effect of not exclusive use.

Furthermore, according to this invention, the height of the air conditioner can be finely adjusted using the adjustment bolt, so even if the lower floor is slightly uneven, the height of the upper cover and the double floor can be matched. This allows the entire double floor to be flat, and the vibrations generated by the air conditioner are absorbed by the vibration-proof elastic body, so vibrations are not transmitted to the room itself or other rooms. Therefore, there is an effect that not only the grounding position of the air conditioner is changed from that of the conventional example, but also that it can actually be used as an air conditioner for a double floor.
