The smoking space is communicated with the smoking space by the intake port 201. The first intake device 21 is a device that sucks air in the smoking space and discharges it into the smoke absorbing space, and is configured as a sirocco fan in the present embodiment. The air sucked into the smoke absorbing space is discharged to the outside through the duct 30. For example, when the smoke separating device 1A is installed indoors, the duct 30 is configured to exhaust air to the outside.

In the smoke absorbing space, a blower device 40 that blows out the air sucked from the intake port 41 in front of the smoking space from the blower port 42 is housed. The intake port 41 is formed on the front side of the blower device 40, and the blower port 42 is formed on the bottom surface of the blower device 40 in a long slit shape in the left-right direction. The blower device 40 is an air flow curtain (air curtain) that blocks a portion of the side wall portion 10 that is opened forward by the air flow generated by the air flow from the blower port 42, that is, the entrance / exit of the smoke separation device 1A. To form. The blower 40 is configured as, for example, a cross-flow fan.

As shown in FIGS. 1 and 4, an opening 203 corresponding to the intake port 41 of the blower device 40 is formed on the front surface of the smoke absorbing portion 20, and the blower port of the blower device 40 is formed at the front end portion on the bottom surface of the smoke absorbing portion 20. Corresponding to 42, a long opening 204 is formed in the left-right direction. According to the blower 40, an air curtain is formed to cover the entrance / exit formed in front of the side wall portion 10. Since the blower 40 sucks the air outside the smoke absorbing space from the intake port 41 and blows it out from the blower port 42, an air curtain having no smoking odor is formed according to the blower device 40. It is assumed that this air curtain is formed on the smoking space side of the door 14.

In the smoking space, a vertical flow path VF extending in the vertical direction is formed along the back surface in the smoking space. As shown in FIG. 3, this vertical flow path VF is formed as a flow path having a rectangular cross section that is long in the left-right direction when viewed from above and is opened vertically by the side wall panels 11, 12, 13 and the partition wall panel 16. (See FIGS. 1 and 3). The partition panel 16 is a plate-shaped member extending in the vertical and horizontal directions (see FIG. 1), and has two side walls whose left and right ends face each other so as to be parallel to the side wall panel 13 in a smoking space. It is connected to panels 11 and 12.

Below such a vertical flow path VF, as shown in FIGS. 1 and 2, a second intake device 50 for discharging the air sucked from the intake port 51 from the exhaust port 52 is provided. The intake port 51 is formed as a long opening in the left-right direction in front of the second intake device 50, and the exhaust port 52 has a shape that matches the vertical flow path VF above the second intake device 50, for example, left and right. It is formed as an opening that is long in the direction. The second intake device 50 is provided in the smoking space so that the intake port 51 is exposed to the smoking space and the exhaust port 52 is connected to the opening in the vertical flow path VF or below the vertical flow path VF. Be distributed.

As shown in FIG. 4, an opening 205 corresponding to an opening above the vertical flow path VF is formed on the bottom surface of the smoke absorbing portion 20, and the vertical flow path VF and the smoke absorbing space are formed through the opening 205. Be communicated. As a result, the air in the smoking space sucked by the second intake device 50 is exhausted into the smoke absorbing space.

Since the wind pressure of the air curtain ejected from above the smoking space by the blower 40 becomes weaker toward the lower side, the smoke separation ability in the state where the door 14 is opened becomes lower toward the lower side of the entrance / exit of the smoke separation device 1A. When the second intake device 50 sucks the air in the smoking space on the lower side of the air curtain, as shown in FIG. 1, an air flow is generated so that the lower part of the air curtain is drawn into the smoking space side, and the air curtain The smoke separation capacity can also be increased on the lower side.

Further, in the state where the door 14 is closed, as described above, the entrance / exit of the smoke separating device 1A is opened downward by a distance O. As a result, the ability of the first intake device 21 to suck air in the smoking space when the door 14 is closed can be enhanced, while the air in the smoking space can flow from below the door 14 to the outside. On the other hand, as shown in FIG. 2, by positioning the intake port 51 of the second intake device 50 below the lower end of the door 14, the smoke separation ability can be maintained.

It is formed by the members 17a and 17b. As shown in FIG. 7, by providing the pipe members 17a and 17b at the rear corners, the dead space in the smoking space can be effectively utilized.

Second intake devices 70a and 70b are provided at the lower openings of the pipe members 17a and 17b to discharge the air sucked from the intake port 71 from the exhaust port 72. The intake port 71 is an opening formed in front of each of the second intake devices 70a and 70b, and the exhaust port 72 is an opening formed upward in each of the second intake devices 70a and 70b. The intake ports 71 of the second intake devices 70a and 70b are positioned below the lower end of the door 14 like the intake ports 51 of the second intake device 50 (see FIG. 6).

As shown in FIG. 8, two openings 206a and 206b corresponding to the upper openings of the vertical flow paths VF2a and VF2b are formed on the bottom surface of the smoke absorbing portion 20, and these two openings 206a and 206b are formed. Through the vertical flow paths VF2a and VF2b, the smoke absorbing space is communicated with each other. As a result, the air in the smoking space sucked by the second intake devices 70a and 70b is exhausted into the smoking space.

In the two embodiments described above, the air in the smoke absorbing space formed above the smoking space is discharged to the space separated through the duct 30, but is sucked from the smoking space in the smoke absorbing space. The clean air may be cleaned. Further, in the above-mentioned two embodiments, the blower 40 and the vertical flow path VF are combined, and the partition portion 60 and the vertical flow paths VF2a and VF2b are combined, but the blower device 40 and the vertical flow path VF2a and VF2b, Alternatively, the partition portion 60 and the vertical flow path VF may be combined.
