Object of the Invention (1) Field of Industrial Application The present invention relates to a smoking hood device, and more particularly to guiding a smoking fume upward and blowing out a smoking fume after clean filtration. The present invention relates to a smoking hood device for shielding a smoking space and an external space from air.

(2) Prior Art It is known that the smoke of cigarettes caused by smoking adversely affects the human body, and coexistence of a smoker and a non-smoker in a living space or a work space is a serious social problem.

Conventionally, the fumes that have been released and diffused into the room by means of the general ventilation system in the room should be inhaled through a wall or ceiling in order to prevent non-smokers from breathing air containing tobacco smoke (hereinafter referred to as "smoking fume"). After that, a smoke hood is suctioned by placing a suction hood on the side of the non-smoker, and the fume is purified through a filter.
A method of returning indoors is widely used.

(3) Problems to be solved by the invention However, according to the above configuration, there are the following drawbacks.

In other words, in the case of, the smoke fume is inhaled from the end of the compartment in the room, so that the smoke fume spreads throughout the room and then is discharged. It is an important capturing means. In addition, since the air heated and cooled is discharged to the outside as it is, it is uneconomical in energy consumption.

In the case of fumes, since the suction direction is perpendicular to the fume ascending flow immediately after the generation of smoking fumes, the control distance is large and the effect of direct suction is significantly reduced. There is a constant airflow for heating and cooling,
This has the effect of turbulence on the updraft of the smoking fumes, causing the fumes to diffuse, which in turn causes the surrounding non-smokers to inhale the smoking fumes, which is still a hygiene problem.

The present invention has been made in view of the above-mentioned conventional problems, and its object is to satisfy the air conditioning energy consumption effect and at the same time capture smoking fumes as an updraft, and after purifying and filtering the fumes, It is an object of the present invention to provide an improved smoking hood device capable of reliably preventing non-smokers from inhaling smoking fumes by blowing air downward to shield the smoking space from the external space.

II. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above object, the present invention provides a box-shaped hood 12 fixed above a smoking seat and having an open lower surface;
It is provided in the vicinity of the opening, and lowers the shielding curtain 36 during smoking, surrounds the periphery of the upper part of the smoking seat, and raises and lowers the shielding curtain 14 to guide the smoking fume, and a filter 16 for purifying and filtering the smoking fume. A fan 18 fixed to the hood 12 for sucking and exhausting the smoking fume filtered by the filter 16, and having an outlet 20 along an inner peripheral edge of the hood 12 opening; The smoking hood device 10 is characterized in that the smoke fume after filtration is blown downward from 20 to air-shield the smoker's smoking space and the external space.

(2) Action According to the smoking hood device according to the present invention, a shielding curtain elevating mechanism for inducing the smoking fume to rise, a filter for cleaning and filtering the smoking fume, and suctioning the smoking fume that has been cleaned and filtered by the filter, It has a fan for exhausting air, and an outlet, and the smoking fume after filtration is blown downward from the outlet to air-shield the smoking space and the external space. In other words, it has a very characteristic configuration in that it sucks upward, not sideways, uses a shielding curtain to guide the airflow, and blows out the fume after clean filtration downward to shield the smoking space from the external space with error. Has become. Therefore, during smoking, the smoking space is stably maintained by the airflow for heating and cooling without causing turbulence,
In addition, the shielding curtain smoothly induces the smoking fume to rise, so that the fume is reliably captured.

Therefore, the circulating flow in the same room is cleaned and filtered, so that the air-conditioning energy consumption effect is enhanced, and the fume trapping property is completely equalized, so that air pollution can be prevented. In addition, the ventilation flow in the centralized heating / cooling type building is always maintained at a purified level.

(3) Embodiment Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a smoking hood device 10 according to an embodiment of the present invention.
FIG. 2 is a schematic front explanatory view of FIG. 1, in which a smoking hood device 10 is suspended from a ceiling plate by, for example, a support rod. This height may be arbitrarily set, but is set to about 2 m from the floor surface in consideration of the elevating distance of the shielding curtain described later.

The smoking hood device 10 includes a hood 12 and a shielding curtain elevating mechanism 14.
, A filter 16, a fan 18, and an air outlet 20.

As shown in FIG. 6, the hood 12 is formed in a rectangular box shape having an open lower surface. And further, the second
As shown in the figure, a frame 22 having an open lower surface is fixedly provided with the fan 18 arranged at the upper part and the filter 16 arranged at the lower part, housed inside the hood 12.

A perforated plate 24 having a large number of perforated holes is provided so as to close the lower surface opening of the frame 22, and a high-performance filter is stretched on the upper surface thereof to remove smoking fumes while passing through the filter 16. It is to be filtered.

An adjustment plate 26 is attached to the periphery of the opening side of the frame 22 so as to be able to move forward and backward with respect to the opening end of the hood 12 on four sides. And the end of this adjustment plate 26 and the hood
The gap between the 12 ends constitutes the outlet 20.

Immediately below the perforated plate 24, there is provided a shielding curtain elevating mechanism 14 for lowering the shielding curtain during smoking, surrounding the area above the smoking seat, and guiding the smoking fume to rise.

That is, as shown in FIGS. 1 and 7, four rod bars 30 are connected via bevel gears 28 along the opening edge of the frame body 22 so as to surround the four circumferences. As is apparent from FIG. 8, a gear is provided substantially at the center of one rod bar 30.
A geared motor 34 is provided in which a gear 32 is fitted and fixed, and a rotating shaft meshes with the gear. Further, a film-shaped shielding curtain 36 made of a synthetic resin or the like is wound around the rod bar 30, and with the rotation of the rod bar 30, the winding is released and lowered downward. In addition, a weight bar 38 is fixed to the tip of the shielding curtain 36, so that the lifting and lowering movement of the shielding curtain 36 is smooth, and when the shielding curtain 36 is lowered to the shielding state, the stability of the shielding state is maintained. Here, the shielding curtain elevating mechanism 14 is formed, and by lowering the shielding curtain 36 at the time of smoking, the smoking fume is raised and guided to the space covered with the shielding curtain 36, and the fume catching property is improved, and This is for guiding to the filter 16.

The lower limit position of the shielding curtain 36 is a low position that is effective for catching smoking fume with a small air flow, and does not disturb the view of the seated smoker, and is set to a height that does not give a feeling of discomfort and oppression. It is preferably set at about 1.35 m above the floor. Further, the raising and lowering of the shielding curtain 36 may not be driven by the geared motor 34, but may be simply raised and lowered manually.

Two ventilation holes 40 are formed in the upper surface of the frame 22, and two ventilation holes 40 are respectively fitted to the ventilation holes 40 so that the suction ports 42 are fitted and mounted on the upper portion of the frame 22. A plurality of fans 18 are provided. This fan 18 has blades 44 as shown in FIG.
The fan is constituted by a centrifugal fan formed in a large number on the radiation, and the air is sucked from the lower part and discharged from the gap between the blades 44 to the radiation.

A fan drive motor 46 is provided inside and at the center of the frame 22, and its rotating shaft projects upward through a shaft hole of the frame 22, and has two guide grooves at its tip. Is fixed.

On the other hand, the rotation shaft of the fan 18 protrudes upward, and the output pulley 50 is fixed to the end thereof. The output pulley 50 and the input pulley 48 are connected via a belt 52. Here, the rotational force of the fan drive motor 46 is transmitted to each fan, so that the fan 18 is driven to rotate. .

The smoke fume that has been cleaned and filtered by the filter 16 sucked from the suction port 42 of the fan 18 is radially discharged by the rotation of the fan and reaches the outlet 20 through the flow path p as shown in FIG. Then, the air flows through the outlet 20 maintained at a predetermined opening degree by the adjustment plate 26 as a high-speed flow, and is discharged substantially radially downward. Here, the air is shielded by the high-speed airflow so as to surround the smoker's smoking space, and is isolated from the external space through the high-speed airflow.

Although not shown, a push button switch or the like is provided near the smoking seat, and is electrically connected to the geared motor 34 and the fan drive motor 46, and these switches are driven by turning on and off the switches.

An illumination lamp (not shown) is provided on the lower surface of the hood 12, and is turned on in conjunction with the ON operation of the switch,
This will compensate for the reduction of existing indoor lighting above the smoker.

Now, in FIG. 4, when the smoker is standing in the smoking seat, the flow of the air supplied and discharged from the air conditioning duct and the like is from the left direction shown by the arrow in the figure. When the smoker sits down as shown in FIG. 5 and turns on a switch provided near the smoking seat, the geared motor 34 and the fan drive motor 46 are driven, and the illumination lamp provided on the lower surface of the hood 12 is turned on. Due to the driving rotation of the geared motor 34, the rotational force is transmitted to one rod bar 30 via the gear 32, and the four rod bars 30 rotate in a direction to cancel the winding of the shielding curtain 36. When the weight bar 38 descends to about 1.35 m above the ground, the switch for the geared motor 34 is turned off. In this case, as shown in FIG. 5, four rounds of the upper space of the smoking seat where the view is not obstructed when the smoker is seated are surrounded by the shielding curtain 36.

In addition, the rotation of the fan drive motor 46 blows air from the outlet 20 to around the smoking area below, and the constant airflow of the air conditioning is stopped from entering the smoking space. Therefore, in the smoking space, there is almost no airflow, and the smoking space is stable. When smoking is performed in this state, the smoking fumes rise upward without any influence from the air-conditioning airflow or the like, and smoothly rise vertically upward. Then, before being cooled, it is guided to the space surrounded by the shielding curtain 36. After passing through the filter 16 and being subjected to clean filtration, the fan 18
As a result, the air is sucked and discharged, and is blown downward as a high-speed flow via the flow path p, thereby shielding the smoking space and the external space from air.

As described above, the smoking fume is not sucked in the right angle direction but is caught in the updraft, so that the fume catching property is greatly improved.

In addition, since air that has been cleaned and filtered in the same room is used as a circulating flow instead of being ventilated by a duct system of the overall air conditioning system, there is no loss in energy consumption for the overall air conditioning, and the air conditioning design itself is easily performed. be able to.

In addition, it is possible to prevent contamination of the ventilation flow of the centralized heating and cooling system in buildings such as hospitals, restaurants, government offices, and companies, thereby contributing to a wide range of environmental purification.

Although two fans are arranged in the embodiment, more fans may be used in order to increase fume cleaning and filtering capacity by the configuration of the smoking seat.

Further, the shielding curtain elevating mechanism may be configured to surround the space above the smoking seat when smoking, and may be configured as a folding type.

III. Effect of the Invention As described above, according to the smoking hood device of the present invention, the smoking fume is guided upward, and the smoking fume after the clean filtration is blown downward to air-shield the smoking space and the external space. To clean and filter the smoking fumes in the circulating flow of the same indoor space, satisfy the energy consumption effect of air conditioning, capture the smoking fumes as updrafts, and place them at the closest control distance Things can be done, it is possible to completely capture smoking fumes,
As a result, air pollution in the indoor space can be reliably prevented, and non-smokers, including smokers, can be reliably prevented from inhaling smoking fumes.

In particular, since the smoking fume after the filtration is blown downward to shield the smoker's smoking space and the external space from air, it is possible to prevent the influence of an obstructive airflow such as a constant airflow for air conditioning,
It is possible to always complete the airflow capture.
