a, an air supply duct 2b, and a power cable 2c connected to the lighting unit 1, which connects the air conditioning unit main body 3 and the lighting unit 1, and allows the lighting unit 1 to be placed above or near the user's head. I am supporting the government as much as possible.

The exhaust duct 2a communicates the inside of the duct unit 2 from the exhaust port 1a provided in the lighting unit 1 to the exhaust duct 3c inside the air conditioning unit main body 3. A single exhaust path is formed up to the exhaust pipe 16. On the other hand, the air supply duct 2b communicates within the duct unit 2 from the air supply section 12 in the air conditioning unit main body 3 to the air outlet 1b of the lighting unit 1.

As shown in FIG. 2, the hood 1d of the lighting unit 1 is shaped like a cone with a rectangular bottom, and its top is connected to the duct unit 2. hood 1d

This power cable 2c passes through the duct unit 2 and the air conditioning unit main body 3 and connects to the hole 3b.
It comes out from the air conditioning unit main body 3.

In the above description, illustrations and explanations of the air conditioning and lighting switches have been omitted.

Next, the action will be explained.

The air taken in from the intake port 4 is adjusted to an appropriate temperature by the heat pump 7, and a part of the air is blown out from the outlet 5 to the underside of the desk 19 by the blower 9, and the rest is sent to the intake duct of the duct unit 2. 2b, and is blown out from the air outlet 1b provided in the lighting unit 1.

The air taken in from the outlet 4 is purified by an air filter 6 disposed inside the intake port 5 when entering the air conditioning unit 3.

The heat pump 7 adjusts the air taken in from the intake port 4 to an appropriate temperature. The coil 7a, which directly adjusts the temperature of the air, has a coiled shape to increase its surface area and is supported above the heat pump 7 away from other members, so that it is more efficient than the air taken in from the intake port 4. Can make good contact.
When the heat pump 7 is operated for heating, the coil 7a is used as a condenser, so that the air that has come into contact with the coil 7a is given heat by the coil 7a and has an appropriate temperature. Conversely, when heat pump 7 is operated for cooling,
Since the coil 7a is used as an evaporator, the air in contact with the coil 7a imparts heat to the coil 7a and becomes at an appropriate temperature. At this time, if the air in contact with the coil 7a is highly humid, some of the water vapor contained in this air will condense and become water, but this water will flow along the surface of the diagonally arranged coil 7a. It flows toward the lower end, falls into the drain pan 8 provided below the coil 7a, passes through the drain branch pipe 17, and reaches the drain main pipe 14 under the floor.

When operating the heat pump 7 to bring the coil 7a to the appropriate temperature, there are parts inside the heat pump 7 that must be cooled. Cooling is achieved by flowing a heat medium through the medium branch pipe 18.

The blower 9 blows out a part of the air heated to an appropriate temperature by the heat pump 7 from the outlet 5 and sends the rest to the duct unit 2. When the blower 9 blows out the air inside the air conditioning unit main body 3, new air is sucked in from the air intake port 4. Of the air sent out by the blower 9, the distribution between the amount of air blown out from the suction port 5 and the amount of air sent to the duct unit 2 can be adjusted by a damper 10. The air sent to the duct unit 2 passes through the air supply duct 2b to the lighting unit 1.
reaches the air outlet 1b opened in the lighting unit 1.
The air was blown out from above onto desk 19. In this way, air outlets are provided in both the air conditioning unit main body 3 and the lighting unit 1 so that the air blows from the air outlet 5 provided in the air conditioning unit main body 3 to the lower body, and the air outlet provided in the lighting unit 1 Since the upper body is blown by the air from the outlet 1b, the temperature around the user can be quickly brought to the user's desired temperature.

On the other hand, smoke generated by smoking is sucked in through the exhaust port 1a provided in the lighting unit 1, passes through the exhaust ducts 2a and 3c provided in the duct unit 2 and the air conditioning unit body 3, and is discharged to the exhaust pipe 16.
reach. At the end of the exhaust pipe 16, there is an exhaust source (not shown), which sends out the air inside the exhaust pipe 16 to the outside. Here, when the smoke generated by smoking rises and reaches a position near the lighting unit 1, it is sucked into the exhaust duct 2a through the exhaust port 1a provided in the hood 1d of the lighting unit 1. Since the light reflecting surface 1f connected to the exhaust port 1a has a canopy shape with the exhaust port 1a as the apex,
This serves as a guide surface to the exhaust port 1a, so that not only the smoke under the hood 1d but also the surrounding smoke can be sucked and discharged from the exhaust port. Of course, this light reflecting surface 1f also fulfills its original role of preventing light diffusion and impact against the fluorescent lamp. As shown in FIG. 2, the hood 1d of the lighting unit 1 covers a considerable portion above the user, and this, together with the suction effect of the light reflecting surface 1f, prevents the user of this unit from smoking. Most of the smoke thus generated can be exhausted from the exhaust port 1a, and the indoor environment can be maintained in a good condition.

In this case, in the lighting unit 1, the exhaust port 1
Since the air outlet a is provided in the center and the air outlet 1b is distributed at several locations on its side, the smoke generated by smoking is surrounded by the wind blowing out from the air outlet 1b.
As if being prevented from flowing out to the outside by an air curtain, the air can be collected under the hood 1d without being diffused into the surrounding area, so that it can be more reliably discharged from the exhaust port 1a. Furthermore, since the blower outlet 1b and the exhaust port 1a are oriented in different directions, it is possible to prevent the so-called short circuit phenomenon in which the air blown out from the blower outlet 1b is immediately sucked in from the exhaust port 1a.

This local air conditioning unit uses the light reflecting surface 1f of the lighting unit 1 to collect cigarette smoke, so the light reflecting surface 1f of the lighting unit 1 serves as a light reflecting surface for the fluorescent lamp and as an exhaust port. Since it can serve as a guide surface, it is not only space efficient, but also aesthetically pleasing, unlike installing the duct unit 2 alone. Moreover, by integrating it with the lighting unit 1,
Since the exhaust port 1a and the air outlet 1b can be provided at a high position, the air can be blown out from both the air outlet 5 opened in the air conditioning unit main body 3 and the air outlet 1b opened in the lighting unit 1, as described above. This can greatly improve air conditioning efficiency.
On the other hand, rising substances such as cigarette smoke can be reliably discharged from the exhaust port 1a, so that the indoor environment can be maintained in a good condition.

In addition, in this embodiment, the air conditioning unit main body 3 is set at the same height as the office desk, so this local air conditioning unit can be used for lighting and as a side table, and can be used not only for air conditioning but also as an air conditioning unit. It is useful even when not in use.

Furthermore, this unit is not integrated with a desk or the like and does not require any special measures to be installed side-by-side, so it can be easily installed side-by-side with an existing desk or table. Furthermore, since it is not integrated with the desk and is lightweight, it can be easily moved to change its location. In order to enable movement of the unit of the present invention, each of the flexible tubes is preferably made telescopic. Also,
Drain main pipe 14 and heat medium main pipe 15 piped under the floor
By providing joints between the exhaust pipes 16a, 15b, and the pipes and ducts in the air conditioning unit main body 3 that are connected to these, attachment and detachment are made possible during movement.

Furthermore, although not shown in this embodiment, by freely changing the angle and direction of the connecting portion between the air conditioning unit main body 3 and the duct unit 2 and the connecting portion between the duct unit 2 and the lighting unit 1, the lighting unit 1 can be easily adjusted. Allows for position and angle adjustment. The means to make this adjustment possible include the duct unit 2 component and the lighting unit 1 component.
It is possible to adopt a configuration in which the connection portion with the device is made flexible by known means.

[Effect of idea]

As explained above, in the present invention, the lighting unit is used to provide the exhaust port and air outlet of the air conditioning unit, so space efficiency is good. In addition, by integrating the lighting unit, the exhaust port and air outlet can be installed at a higher position, making it possible to greatly improve air conditioning efficiency and exhaust efficiency, thereby reducing the environment around the user. Can be kept in good condition.

Further, in the present invention, an opening is provided in the lighting unit supported by a duct unit communicating with the air conditioning unit main body, so that air sent from the air conditioning unit main body is sent out to the outside. Therefore,
This unit does not need to be integrated with the desk, and can provide air conditioning effects to other desks, etc.
It is also easy to introduce into existing offices, etc. Further, since there is no need to provide a special opening on the desk or the like, there is no restriction on the space on the desk when using the desk.
