Description

  The present invention relates to a smoking area with an air cleaner capable of simply installing a smoking area in a corner of a structure.

  Currently, there are roughly three types of air purifiers that remove cigarette smoke. These are: 1. A type that directly sucks and removes smoke. 2. A type where a certain space is enclosed by an air curtain, etc., so as not to let smoke go out of the enclosure, and sucked and removed inside the enclosure. This is a combination of the above 1 and 2, which is a type that directly sucks and removes smoke and prevents the smoke that could not be sucked out by an enclosure such as an air curtain.

1. The following types of the present applicant are known.
JP-A-9-121947
2. The following types are known. Japanese Utility Model Publication No. 7-35927
3. The following types of the present applicant are known. JP 2001-174011 A

  However, these air purifiers can remove a considerable part of dust and tar contained in cigarette smoke, but they have the function of removing harmful gases, especially carbon monoxide generated during smoking. There is nothing currently. Therefore, even if these air purifiers are installed in the room of the structure, an increase in the carbon monoxide concentration in the room is inevitable unless sufficient ventilation is performed. In addition, it is difficult to sufficiently remove odors with an air cleaner, and odors gradually accumulate in the room unless ventilation is performed. From this point of view, the Health Promotion Law was enacted and the following guidelines for smoking areas should be presented.

  In other words, if one room of the structure is a dedicated smoking area, or a part of the room is completely enclosed as a smoking area, sufficient ventilation will be performed to increase the concentration of carbon monoxide and accumulation of odors. There is a need to prevent and prevent cigarette smoke from leaking out of those smoking areas. For this reason, at the entrance and exit of the smoking area, there is always a controlled air flow inward of the smoking area of at least 0.2 m / sec. Even when the smoking area door is opened, tobacco smoke leaks from the inside of the smoking area. It is necessary not to.

  At present, smoking areas such as those indicated in the above guideline have only a simple structure in which a ventilation fan is separately provided in addition to the normal ventilation for management of buildings and the like to ventilate the inside of the smoking area.

  As described above, the air cleaners of Patent Documents 1 to 3 have almost no carbon monoxide removal function having a deodorizing function, and those other than Patent Documents 1 to 3 also have a carbon monoxide removal function. There is currently no one with. Therefore, even if these air purifiers are installed indoors, it is necessary to provide sufficient ventilation, and the air conditioning load increases during the season when there is a temperature difference between the inside and outside, particularly in the winter and summer seasons. Because most rooms are not given special consideration for this high air-conditioning load, summer is hot and winter is cold, and avoiding this will increase the carbon monoxide concentration and odor intensity in the room this time. And no longer comfortable indoors. In order to cope with this, it is necessary to install a separate air conditioner in the room.

  On the other hand, the smoking area indicated by the above guidelines can be evaluated in that it clearly separates smokers and non-smokers and completely eliminates the effects of tobacco smoke on non-smokers. However, as described above, the air conditioning load increases in the winter and summer seasons when there is a temperature difference between the indoor and outdoor environments. As described above, most of the rooms designated as smoking rooms have no special consideration for this high air conditioning load. Therefore, it becomes necessary to install a separate air conditioner. Moreover, this is a case where a room that can be designated as a smoking area can be secured. If such a room cannot be secured, a part of the room will be completely partitioned if you try to follow the guidelines of the Health Promotion Act. There is no smoking area, and air conditioning equipment for exhaust must be installed separately in this smoking area. However, installation of such air conditioning equipment in tenant buildings may be difficult due to the relationship with the building owner, and in addition, it is technically difficult and poor in appearance, so it is very difficult in most cases. It is.

  Therefore, the present invention has been made in view of the above circumstances, and does not simply install an air purifier in a room, but can follow the guidelines of the health promotion method even in a room where it is difficult to construct an air conditioning facility for exhaust, It is an object of the present invention to provide a smoking area with an air purifier that can be easily installed and removed in a corner of the room and can reduce the air conditioning load in winter and summer.

The air is discharged to the outside of the section and a controlled air flow of at least 0.2 m / sec is generated at the doorway toward the inside of the room. Circulate Characterized in that the.

  The invention described in claim 2 is characterized in that an air curtain blowing device is provided at an upper part of the entrance / exit.

  The invention described in claim 3 is characterized in that a sterilization ion generator is provided at the air outlet.

  The invention according to claim 4 is for distributing the clean air into the air outlet and the exhaust pipe in the airtight space located at the branch point to the exhaust pipe on the downstream side of the air cleaner and the fan. A damper is provided.

  According to a fifth aspect of the present invention, an exhaust attachment is provided on the ceiling portion instead of the exhaust pipe, and the exhaust attachment includes a connection port connected to an external ventilation port, a partial exhaust port discharging to the outside of the unit, And a distribution valve that divides the cleaning air into the connection port and the partial exhaust port.

The present invention has the following effects.
That is, according to the first aspect of the present invention, the smoke of the cigarette smoke introduced into the airtight space together with the air around the suction port is removed by the air purifier, and a part of the purified air is discharged to the exhaust pipe. A 0.2m / sec controlled air flow is generated from the outside to the outside and then inward at the entrance / exit, and the remaining part is blown out from the air outlet to form an air flow toward the suction port and circulates with cigarette smoke. I try to let them. Therefore, the guidelines under the Health Promotion Act can be observed, the air conditioning load in winter and summer can be kept the same as before, and the smoke from the smoker immediately takes on the airflow toward the inlet. Does not affect smokers. In addition, the air purifier is not simply installed in the room, but even in a room where it is difficult to construct the air conditioning equipment for exhaust, there is an effect that it can be freely installed and removed at one corner.

  In the invention according to claim 2, the air curtain is blown down from the air curtain blowing device, and the open / closed port is closed in an airflow manner. Therefore, in addition to the above effects, it is possible to sufficiently secure the air velocity of 0.2 m / sec of the control airflow at the entrance and exit, and furthermore, it is possible to reduce the amount of purified air discharged from the exhaust tube to the outside of the part or to the external ventilation port. There is an effect that the influence of the cleaning air on the room can be reduced.

  According to a third aspect of the present invention, the sterilization ions released from the sterilization ion generator ride on an airflow from the outlet toward the outlet and circulate in the room. Therefore, in addition to the above effects, the sterilization ions work in the process of circulating in the room, and there is an effect of sterilizing the room.

  According to a fourth aspect of the present invention, the cleaning air is freely divided into the outlet and the exhaust pipe by the distribution damper. Therefore, in addition to the above effects, the distribution damper can control the control wind speed at the entrance and exit of the room and the influence of the cleaning air on the room, and can also control the air flow from the outlet to the inlet through the room. is there.

  According to the fifth aspect of the present invention, the purified air divided by the distribution damper is further freely divided into a connection port and a partial exhaust port by a distribution valve of the exhaust attachment. Therefore, in addition to the above effect, there is an effect that the influence of the cleaning air on the room and the ventilation amount of the external ventilation port can be controlled.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

An air purifier 11 and a fan 12 are provided in an airtight space 10 between the cylinder 9 and the fan 12 is operated to suck cigarette smoke from the suction port 5. And a part of the purified air is discharged from the exhaust tube 9 to the outside of the room 4 to generate a control air flow 13 of at least 0.2 m / second toward the inside of the room 4 at the entrance / exit 3, and the remaining part is blown out. 8 blows out to form an air current 7, and smoke is smoked into it. It was is obtained so as to circulate.

  The room 2 of the structure is a room such as a building, a vehicle, a ship, an aircraft, and the like, and there is no particular limitation as long as it is a space that can be made by people.

  The room 4 is a package type that can be installed in the room 2 of the structure and includes the ceiling portion 6 and a partition 20 that covers a side surface, and can be assembled and disassembled. The room 4 shown in FIGS. 1 to 4 is a type that is installed using the L-shaped wall surfaces 21 and 22 of the room 2 and is open without partitions 20 on the two side surfaces. The room 4 can be expanded by connecting one or more packages shown in FIGS. 1 to 4 and connecting two or more packages.

  Since the entrance / exit 3 is a type that does not have a door in which a part of the side surface of the room 4 is simply opened, a person can freely enter and exit. Of course, a door described in detail later may be provided at the doorway 3. An air curtain blowing device 23 is provided at the upper part of the inlet / outlet 3. When the air curtain 24 is blown down from the air curtain blowing device 23, the opened / outlet port 3 can be closed in an air flow. Closing the entrance / exit 3 in an air flow substantially reduces the opening area of the entrance / exit 3, and therefore it is possible to sufficiently secure a 0.2 m / sec wind speed of the control air flow 13 at the entrance / exit 3, In addition, the amount of cleaning air discharged from the exhaust tube 9 to the outside ventilation port (not shown) provided outside the room 4 or inside the room 2 of the structure can be reduced. The impact can be reduced.

The above-described airtight space 10 includes the box 30 and a circulation duct 33 provided between the upper surface of the box 30 and the lower surface of the ceiling portion 6 and provided along the lower surface of the ceiling portion 6. It consists of.

  As described above, the air cleaner 11 and the fan 12 are provided in the box body 30, and the air cleaner 11 is connected to the inside of the box body 30 from the suction port 5 as shown in FIG. 5. A prefilter 34 that removes relatively large particles of cigarette smoke sucked in, an electric dust collector 35 that removes fine particles that have passed through the prefilter 34, ultrafine particles that have passed through the electric dust collector 35, odor components, etc. And a deodorizing filter 36 for removing water. Further, instead of the electric dust collector 35, a mechanical filter capable of removing at least fine particles may be used, and a high-performance mechanical filter having a function of removing ultrafine particles and odor components may be used in combination.

  The fan 12 can suck the cigarette smoke drifting around the suction port 5 into the box 30 together with the surrounding air, and passes through the air cleaner 11, the circulation duct 33 and the exhaust pipe 9. In addition, the conditions having the basic capacity and pressure required to form the air flow 7 that blows out from the outlet 8 at the most downstream side of the circulation duct 33 and flows toward the inlet 5 are added. There is no limitation in particular.

  Further, in the airtight space 10 located at the branch point to the exhaust pipe 9 on the downstream side of the air cleaner 11 and the fan 12, that is, in the circulation duct 33 downstream of the branch pipe 37 in the airtight space 10, A distribution damper 38 for separating the cleaning air is provided in the exhaust pipe 8 and the exhaust pipe 9. The distribution damper 38 can freely divide the amount of clean air into the air outlet 8 and the exhaust tube 9. Accordingly, the distribution damper 38 can control the control air flow 13 at the entrance / exit 3 of the room 4 and the effect of the cleaning air on the room 2, and the air flow 7 from the air outlet 8 circulated in the room 4 to the air inlet 5 is also generated. You will be able to control.

  The exhaust tube 9 is installed on the ceiling portion 6, and has a plurality of small holes 41 formed on the eight sides of the octagonal cylinder 40, and the cleaning air is discharged from these small holes 41 and diffused into the room 2. It is. The exhaust tube 9 can be replaced with an exhaust attachment 51 described in detail later.

A direction changing plate 42 is provided in the circulation duct 33 so as to face the outlet 8, and the direction changing plate 42 changes the direction of the purified air that has passed through the circulation duct 33 from the outlet 8. The airflow 7 is directed toward the suction port 5.

  In addition, a sterilization ion generator 43 is provided at the air outlet 8, and the sterilization ions released from the sterilization ion generator 43 ride on the air flow 7 from the air outlet 8 toward the blowout suction port 5. Circulate in room 4. Accordingly, the sterilization ions work in the process of circulating the sterilization ions in the room 4, and the entire smoking area 1 with the air cleaner can be sterilized.

Next, the usage method of the smoking area 1 with an air cleaner which becomes the said structure is demonstrated.
First, the installation location of the structure room 2 is confirmed, and the size of the smoking area is determined. Since the L-shaped wall surfaces 21 and 22 of the indoor 2 of the structure are used, the smoking area 1 with an air purifier that is open without the partition 20 on the two side surfaces as shown in FIGS. Decide on one package or more based on the size of the smoking area. Here, as shown in FIG. 1, as a single package, a smoking area 1 with an air purifier is installed, and, for example, the device is pre-adjusted such as adjusting the opening degree of the distribution damper 38. Next, when a person enters from the entrance 3, it is detected by a human sensor or turned on, and as shown below, all functions in the smoking area 1 with an air cleaner are activated.

  That is, the air curtain 24 is blown down from the air curtain blowing device 23, the open / closed entrance / exit 3 is closed in an air flow, and further, the fan 12 is activated and air enters the box 30 from the suction port 5, Along with this, air is discharged from the exhaust tube 9, and air is also blown out from the air outlet 8 to form an air flow 7. When a person entering the smoking area 1 with an air purifier smokes, the cigarette smoke immediately enters the airflow 7 and enters the box 30 through the suction port 5, and relatively large particles are generated by the prefilter 34 of the air purifier 11. Fine particles that have been removed and could not be removed by the pre-filter 34 are removed by the electrostatic precipitator 35. Further, ultrafine particles, odor components, etc. that could not be removed by the electrostatic precipitator 35 are removed by the deodorizing filter 36. Cleaned air with almost no dust or tar content. The cleaning air enters the circulation duct 33 and is divided into the outlet 8 and the exhaust pipe 9 by the opening degree of the distribution damper 38 adjusted in advance, and a part of the cleaning air enters the room 2 from the exhaust pipe 9. The remaining portion of the purified air that has been diffused and exhausted and passed through the circulation duct 33 is changed in direction by the direction changing plate 42, blown out from the outlet 8, and circulated as an airflow 7 toward the inlet 5. The circulated airflow 7 is re-introduced with cigarette smoke and enters the box 30 through the suction inlet 5 and is operated in the same manner as described above.

  On the other hand, a part of the purified air is diffused and exhausted from the exhaust tube 9 into the room 2, so that air corresponding to the amount enters the smoking area 1 with the air purifier from the entrance / exit 3, which becomes the control airflow 13, and the cigarette No smoke comes out of the entrance 3 Further, when the air curtain device 23 is provided, the open / close port 3 is closed by the air curtain 24 in an air flow, and the air velocity of 0.2 m / sec of the control air flow 13 can be secured sufficiently and easily. At the same time, as described above, the influence of the cleaning air on the room 2 can be controlled, and the air flow 7 toward the suction port 5 can also be controlled. Further, sterilization ions are released from the sterilized ion generator 43 to the circulated air flow 7, and the entire smoking area 1 with the air purifier can be sterilized by the sterilization ions.
