Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoking chamber unit arranged in a non-smoking room.

[0002]

2. Description of the Related Art Conventionally, an air purifier used in a smoking room or the like sucks tobacco smoke and collects particulate matter contained in the smoke through a filter, and then purifies the purified air again in the smoking room. Often returned to.

[0003]

However, although the air cleaner can collect particulate matter such as smoke, it cannot remove carbon monoxide, carbon dioxide, odorous substances and other harmful gas substances. , These are returned to the smoking room again. Usually, a deodorizing filter that uses adsorption or a photocatalyst is used to collect the gas body, but it is difficult to remove the odor and the like by only passing the deodorizing filter once.

Therefore, the concentration of the gas body gradually increases in the smoking room, and each time the smoker enters or leaves the smoking room, the gas body also flows out of the smoking room and pollutes the non-smoking room. Become. In general, in order for the gas in the smoking room not to flow back to the outside, an air flow with a flow velocity of 0.2 m / sec or more is required from the non-smoking room to the smoking room.

Therefore, the air in the smoking room is exhausted to the outside,
When fresh outdoor air is introduced into the non-smoking room, air flowing from the non-smoking room to the smoking room is also generated, and such a problem is solved. However, when the smoking room and the non-smoking room are heated and cooled, cold air or warm air is also discharged, which causes a thermoeconomic problem.

In addition, since the buildings are close to each other especially in an urban area or a residential area, if the air in the smoking room is simply discharged to the outside, a secondary problem of scattering the gas body occurs. This problem can be solved by providing a high chimney and exhausting it from here, but depending on the situation, it may require a long chimney construction or the chimney installation itself may be difficult.

An object of the present invention is to solve the above problems and to provide a smoking chamber unit which eliminates both particulate matter and gas bodies in smoke generated by smoking and has a small thermo-economic loss. .

[0008]

In order to achieve the above object, a smoking chamber unit according to the present invention comprises a smoking chamber formed by partitioning a non-smoking room and the exhaust of the smoking chamber to the outside. It is provided with a first fan for discharging, a second fan for sucking air from the outdoors into the room, and a heat exchanger for exchanging energy between the exhaust air to the outdoors and the intake air from the outdoors. And

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail based on the illustrated embodiments. FIG. 1 shows a schematic view of a smoking chamber unit in the present embodiment. The chamber 1 is assembled into a frame shape by a frame 2 made of, for example, a steel frame, and a flame-retardant sheet 3 is stretched around the ceiling portion and the periphery of the chamber 1 and is partitioned and arranged in a non-smoking room 4. And non-smoking room 4
The sheet 3 is provided with a gap of, for example, about 20 cm from the floor surface so that the air flows from the inside to the chamber 1. Further, a part of the seat 3 is provided with an entrance / exit 5 for entrance / exit, and a caster 6 for enabling movement in the non-smoking room is provided under the frame 2 as required.

The air purifier 7 is fixed to the upper part of the chamber 1 by means such as hanging from the ceiling. An exhaust duct 8a is provided at the outlet of the air purifier 7,
An exhaust fan 9 is provided in the duct 8a, and the other end of the duct 8a is connected to the heat exchanger 10. The exhaust duct 8b from the heat exchanger 10 is open to the outside through a vent hole (not shown) provided in the wall 11.

On the other hand, from the outside, an intake duct 12a is connected to the heat exchanger 10, and a duct 12b having an open end is piped from the heat exchanger 10 into the non-smoking room 4 outside the chamber 1, An intake fan 13 is provided in the duct 12b. The exhaust duct 8b and the intake duct 12a are used by dividing the same tubular body 14 into two.

The air purifier 7 may be a simple filter or an electric dust collector. When a fan is attached to the air purifier 7, the exhaust fan 9 can also serve as the fan of the air purifier 7. In addition, a filter capable of exhibiting sufficient performance for removing gas is provided around the air cleaner 7 or the exhaust duct 8a.
It can also be arranged in 8b.

The heat exchanger 10 has, for example, a large number of passages each having a honeycomb-shaped cross section on the exhaust side and the intake side, and the exhaust passage and the intake passage are in contact with each other through a wall portion having a good thermal conductivity. Things can be used.

The smoke emitted from the cigarette in the smoking chamber 1 is
The air is sucked into the air purifier 7 by the exhaust fan 9 through the exhaust duct 8b. The air from which particulate matter such as smoke has been removed by the air purifier 7 passes through the heat exchanger 10 and is discharged to the outside through the exhaust duct 8b. In addition, the intake fan 1
By the suction of 3, the fresh air is introduced into the non-smoking room 4 from the outside through the air intake duct 12a and the heat exchanger 10. In this process, cold air or warm air contained in the discharged air is used by the heat exchanger 10 to cool or warm the sucked air. In addition, heat exchange is performed not only in the heat exchanger 10 but also in the partition portion by partitioning the pipe body 14 and discharging and suctioning as in the present embodiment.

As described above, the outdoor air is introduced into the non-smoking room 4 and the flow of the air from the non-smoking room 4 into the chamber 1 is caused, and the gaseous substances, carbon monoxide and carbon dioxide produced by smoking are produced. Air containing gas such as is rarely circulated from the chamber 1 to the non-smoking room 4.

In the present embodiment, by using such a smoking chamber unit, a gas body such as carbon monoxide or carbon dioxide which cannot be removed only by the air cleaner 7 can be released to the outside. Further, by removing the particulate matter with the air cleaner 7, the duct 8 and the heat exchanger 10 can be prevented from being contaminated, and the particulate matter produced by smoking is not discharged outdoors.

Furthermore, by using the heat exchanger 10, it is possible to effectively utilize the cold air and warm air of the indoor air without wasting them. For example, in summer, cool air from indoor cooling cools the air sucked from the outside in the heat exchanger 10, and in winter, the warm air exhausted warms the air from the outside.

Further, by providing the casters 6, as long as the duct 8 can be moved, it can be moved to any place in the non-smoking room 4 and used.

In the present embodiment, fresh outside air is introduced into the non-smoking room 4 outside the chamber 1, so that air flows from the non-smoking room 4 to the chamber 1 and the inside of the chamber 1 It is unlikely that the non-smoking room 4 is contaminated by the air flowing back into the non-smoking room 4. Although there are some problems, it goes without saying that the external air may be directly introduced into the chamber 1.

The air purifier 7 is not indispensable and may be omitted if smoke can be discharged outdoors.

Further, the ducts 8a and 12b provided between the heat exchanger 10 and the outside are used by dividing the same pipe body 14, but separate pipes may be used.

[0022]

As described above, the smoking chamber unit according to the present invention can remove not only the particulate matter contained in the smoke of cigarettes but also carbon monoxide, carbon dioxide, and other gas bodies, and the thermal economy can be improved. It is also advantageous.
