Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner mounted on a double floor (free access floor) so that conditioned air sent from the underfloor space is ejected into the room.

[0002]

2. Description of the Related Art In the case where a double floor is formed by laying floor panels on a floor base made of concrete or the like with appropriate gaps, conditioned air is jetted into the underfloor space between the floor base and the floor panels. Alternatively, an air conditioning system has been proposed in which conditioned air is taken out from the underfloor space by arranging an air conditioning duct in the underfloor space.

As an example, in Japanese Utility Model Laid-Open No. 4-12949 as a prior art, an air passage opened to the lower surface of a furniture such as a cabinet or a partition is formed in the interior of the furniture so that the space from the underfloor space can be removed. An invention is described in which conditioned air is introduced into the interior of furniture and the conditioned air is ejected into a room from an ejection portion formed in the upper part of the furniture.

[0004]

According to this prior art, since the furniture can also be used as an air conditioner, the space in the room can be effectively used, and the blast of conditioned air can be operated indoors. Since it can be installed in a region close to the person who operates the air conditioner, it has an advantage that the efficiency of cooling and heating can be improved as compared with the conventional air conditioning system in which the jet portion is provided on the ceiling surface or the wall surface.

However, in this prior art, since the conditioned air only spouts from the upper part of the furniture toward the room, the conditioned air excessively hits the human body, or the upper body hits the conditioned air, but at the feet. There was a problem that fine air conditioning was still inadequate, as was the case that conditioned air did not hit at all. An object of the present invention is to provide an air conditioner that solves this problem.

[0006]

In order to achieve this object, the present invention comprises a hollow main body adapted to be installed on a double floor, the main body being provided with conditioned air from an underfloor space in the double floor. An intake port for taking in conditioned air, an outlet for ejecting the conditioned air into the room, and an air outlet capable of being connected to the air passage in the furniture with the conditioned air ejecting section placed on the double floor. Further, there is provided a switching means for switching the conditioned air between a state in which the conditioned air is ejected from the ejection portion of the furniture and a state in which the conditioned air is ejected from the blowout port of the main body.

[0007]

According to this structure, by operating the switching means, the conditioned air can be blown into the room only from the outlet of the main body of the air conditioner in the vicinity of the floor surface, or the conditioned air can be supplied to the upper part of furniture or the like. It can be switched so that it is ejected only from the ejection part provided in the room or is ejected into the room from both the ejection port of the main body of the air conditioner and the ejection part of the furniture.

Therefore, for example, at the beginning of the morning at the beginning of work, conditioned air is ejected from both the air conditioner and the furniture to cool and heat both the feet of the person and the upper half of the body to bring the room to a predetermined temperature. When conditioned air is ejected from only the air conditioner to heat and cool only the feet, or when warming in winter, the warm air is light and rises, so that only the air conditioner ejects the air into the room. While improving heating efficiency by cooling air in summer, by utilizing the fact that the cool air is heavy, conditioned air is ejected only from the top of the furniture to improve cooling efficiency. It can be done.

Injecting gas into the room near the floor surface,
The conditioned air can be jetted into the room only from the jetting portion 8 of the partition panel 1, or the conditioned air can be jetted from both the air conditioner 6 and the second partition panel 1.

Therefore, for example, at the start of work, conditioned air is jetted from both the second partition panel 1 and the air conditioner 6 to quickly cool and heat the room, and when the temperature in the room reaches a predetermined temperature, only the air conditioner 6 is used. Like blowing out conditioned air,
Alternatively, it is said that when warming in winter, warm air is blown from only the air conditioner 6 to warm a person from the feet, and when cooling in summer, cool air is blown only from the blowout portion 8 of the partition panel 1 to cool the person from the head. As described above, it is possible to perform detailed heating and cooling according to the situation.

The three-dimensional relationship with the opening angle θ3 of 38a is set so that θ3 = θ2 + θ1, and the tapered cylindrical body 32 is rotated while the air supply hole 35 is completely blocked by the tapered cylindrical body 32. By allowing the blowout port 15 to be opened and closed by controlling the blowout port 15, the ejection amount from the blowout port 15 can be adjusted while the air supply to the partition panel 1 is blocked, and the tapered cylindrical body 32 is approximately 90 mm wide. The air supply to the partition panel 1 can be interrupted by rotating the air supply hole 35 by opening and closing the air supply hole 35 about a degree.

Further, an intake port 41 communicating with the air passage 7 is provided on the surface of the partition panel 1 so as to project therefrom.
The air supply port 16 of the air conditioner 6 is connected by a hose 29, and a slot 42 that penetrates vertically is formed in a portion of the top plate 3 near the partition panel 1. . With such a configuration, for example, when an office worker performs normal office work, conditioned air is ejected from the ejection portion 8 of the partition panel 1, while the OA device 43 with a display device is placed on the top plate 3. In this case, the hose 29 can be removed, and cool air from the air supply port 16 can be jetted above the desk from the long slot 42 of the top plate 3 to cool the OA equipment 43.

In addition, when a heat-generating device 44 such as a controller for OA equipment is placed on the floor below the top plate 3,
It is also possible to cool the appliances 44 with the cold air ejected from the air outlet 15 of the air conditioner 6. In each of the above-described embodiments, the air-conditioning device is provided with the switching means. However, in the case where the blowout portion of the furniture is provided with the air volume adjusting mechanism for blocking the blowout of the conditioned air from the blowout portion, Is
The air volume adjusting mechanism may also be used as the switching means, and the air supply port of the air conditioner may be simply connected to the air passage of the furniture.

The air conditioner according to the present invention can be connected not only to a partition panel or a desk, but also to other furniture such as a cabinet having a blowout part, and the shape of the air conditioner or the form of the switching means. Needless to say, the present invention is not limited to the embodiment and various other forms can be adopted.
