Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a separate type air conditioner in which the air conditioner is separated into two parts, an outdoor unit and an indoor unit. related to what was done.

[Background Art and Problems Therein] Conventionally, separate type air conditioners are known in which an outdoor unit having a compressor, a heat exchanger, a blower, etc. is installed under the floor. This is because the temperature under the floor is about 2 to 4 degrees Celsius higher than the outside air in winter, and about 2 to 4 degrees Celsius lower in summer, so this temperature difference can be used to improve the efficiency of air conditioners. This was because it not only saves space compared to when installed outdoors, but also has a good appearance and is useful for ventilation under the floor.

However, when installing an outdoor unit under the floor like this, especially if the foundation to which the outdoor unit is attached is a fabric foundation, the outdoor unit must be completely sealed between the outdoor unit and the fabric foundation. A leak of outside air occurs at the point where the unit is attached to the foundation, and the efficiency of ventilation under the floor by the unit outside the branch where this leak occurs decreases, and feng shui from wind and rain enters the underfloor through the gaps, causing moisture to cause damage to the underfloor, etc. The problem is that it is negatively affected.

[Purpose of the invention] The purpose of the invention is to provide a separate air conditioner that prevents air from leaking inside and outside the foundation and from infiltrating rainwater at the foundation of an outdoor unit installed under the floor.

[Means and effects for solving the problems] The present invention provides a separate air conditioner in which an outdoor unit is installed under the floor and an indoor unit is installed indoors, which is formed based on one end of the outdoor unit. The flange portion formed around one end of the outdoor unit is placed along the outer surface of the foundation, and the opening is inserted between the facing surfaces of the flange portion and the outer surface of the foundation. The present invention is characterized in that a continuous sealing material is interposed so that the flange portion and the outer surface of the base are fastened by a member that passes through the sealing material.

Then, the sealing material is used to seal the entire circumference of the opening, and the fastening member that passes through the sealing material improves the surface adhesion between the sealing material and the flange and the outer surface of the foundation. The purpose is to achieve the above objective by ensuring sealing performance.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

In the sectional view of FIG. 1, a building 3 is supported on a cloth foundation 2 installed on the ground 1, and a pedestal 5 is provided on the ground 1 located below the floor 4 of this building 3. . The cloth foundation 2 is provided with an opening 6 passing through the cloth foundation 2, and an outdoor unit 7 of a separate air conditioner is inserted through the opening 6.

This outdoor unit 7 is equipped with a compressor 8, a blower 9, and a heat exchanger 10 functioning as an evaporator or condenser inside, and a filter 11 on the outer periphery, like a normal outdoor unit.

One end of the outdoor unit 7 is connected to the cloth foundation 2.
One end of the opening 6 is supported in a sealed state through a sealing material 12, and the other end is supported by the pedestal 5.

As shown in the perspective view of FIG. 2, the sealing material 12 is constructed by wrapping a ring-shaped member made of an elastic material such as rubber or a relatively thick elastic adhesive tape multiple times. The opening 6 serves both as a seal between the cloth foundation 2 and the outdoor unit 7 and as vibration isolation.

A flange portion 13 is integrally fixed to the front end of the outdoor unit 7 by welding or the like, and a sealing material 14 is also interposed between the flange portion 13 and the outer surface of the cloth foundation 2.

This sealing material 14 is made of the same material as the sealing material 12 described above, and is formed in a ring shape that goes around the periphery of the opening 6 of the slab 2.
The seal material 14 is inserted through the seal material 14.
Bolts 15 are installed to fasten the flange portion 13 and the slab 2 together by sandwiching the bolts 15.
The outdoor unit 7 is fixed to the slab 2 by this.

Furthermore, a louver 16 is removably provided on the front surface of the flange portion 13 to rectify the direction of air discharged from the outdoor unit 7 to the outside in a diagonally downward direction and to prevent rainwater from entering. .

An electrical equipment box 17 is provided at the rear of the outdoor unit 7, and an electrical wiring 18 is connected to the electrical equipment box 17. A heat medium pipe 19 is provided, and these electrical wiring 18 and heat medium pipe 19 are connected to an outdoor unit of a separate type air conditioner (not shown).

Note that an underfloor 20 is formed between the floor 4 of the building 3 and the ground 1.

In such a configuration, when the outdoor unit 7 is driven, the air in the underfloor 20 is absorbed from the rear of the outdoor unit 7 by the blower 9, and the air is absorbed by the heat exchanger 1.
After heat exchange at 0, it is discharged from the louver 16 to the outside.

At this time, one end of the outdoor unit 7 is secured to the fabric foundation 2 by the action of the sealing material 14 provided inside the flange portion 13 and the sealing material 12 interposed between the opening 6 and the outdoor unit 7. Since the inside and outside are sealed, outdoor air will not leak from the part of the fabric foundation 2 that supports the outdoor unit 7 and create a so-called short circuit, so the air inside the underfloor 20 can be effectively exhausted to the outside. , under the floor 20
It can provide sufficient ventilation.

According to this embodiment as described above, when the outdoor unit 7 is attached to the opening 6 of the cloth foundation 2, the outdoor unit 7 is attached to the sealing material 12 and the sealing material 1.
4, the surface is in close contact with the entire circumference, and sealing and vibration isolation can be achieved reliably.

In particular, the sealing material 14 is interposed between the flange portion 13 and the outer surface of the cloth foundation 2, and can ensure sealing performance over the entire circumference of the opening 6.
It is possible to reliably prevent water ingress, etc.

Further, since the flange portion 13 and the cloth foundation 2 are fastened together with the bolts 15 passing through the sealing material 14, the sealing material 14 is attached to the flange portion 1 as the bolts 15 pass through the sealing material 14.
3 and the outer surface of the cloth foundation 2, the sealing performance around the opening 6 can be further ensured.

Due to the reliable preventive sealing and vibration-proofing properties of the sealing materials 14 and 12, the outdoor unit 7 can effectively ventilate the underfloor 20, and the vibrations caused by the compressor 8 of the outdoor unit 7 can be suppressed from the building 3. There is no need to inform the neighbors, and the livability of building 3 is not affected.

Furthermore, as mentioned above, the under-floor area 20 is warm in winter and cool in summer, which helps the outdoor unit 7 to function as a heat pump, improving the operating efficiency of the outdoor unit 7. From a different perspective, it has an energy-saving effect. have.

Furthermore, since the under-floor area 20 can be sufficiently ventilated, the lifespan of the building 3 can be extended due to the moisture-proofing effect.

Furthermore, since the outdoor unit 7 is not affected by rainwater or sunlight compared to a unit left outdoors, the lifespan of the outdoor unit 7 can be extended, and not only does it save space, but it also improves its appearance. It can also be done well.

In particular, by providing a flange portion 13 at the outer end of the outdoor unit 7 and covering it from the outside of the opening 6 of the fabric foundation 2, it is possible to block rainwater from rebounding from the ground, and also to prevent the flange portion 13 and the fabric foundation 2 from rebounding. Since the sealing material 14 is provided in between, the sealing material 14 is provided continuously around the entire circumference, so that it is possible to reliably prevent rainwater etc. from entering the opening 6.

In addition, in this embodiment, since the sealing material 12 is provided between the inner periphery of the opening 6 and the outdoor unit, which is continuous over the entire periphery, it is possible to more reliably prevent rainwater etc. from entering from the opening 6 into the underfloor 20. It can be prevented.

Furthermore, since the outer end of the outdoor unit 7 is supported by the flange portion 13, it is possible to arbitrarily set the distance between the periphery of the outdoor unit 7 and the opening 6, and the entire circumference of the distance portion can be set arbitrarily. By adjusting the thickness of the sealing material 12 interposed therein, the desired vibration damping performance can be reliably exhibited.

In addition, in implementation, the sealing material 12 may be omitted as appropriate, but by providing a double seal with the sealing materials 12 and 14, good waterproof sealing performance can be achieved.

Further, the sealing material 12 and the sealing material 14 may have only a simple sealing function if vibration of the outdoor unit 7 is not a problem.

On the other hand, although the outdoor unit 7 was equipped with a compressor 8, a blower 9, a heat exchanger 10, etc., the present invention is not limited to this.
It may be a separate type air conditioner such as a so-called remote condenser type having only the blower 9 and the heat exchanger 10, and its name does not matter.

Further, the opening 6 is not limited to a hole-shaped hole passing through the cloth foundation 2 as shown in the figure, but may be a concave-shaped one with an upper opening.

[Effects of the invention] According to the invention as described above, when the outdoor unit is installed under the floor, it is possible to sufficiently seal the foundation and the outdoor unit, and the ventilation performance under the floor can be fully demonstrated. effective.
