Description

  In the present invention, a room is divided into partitions and simply made into private rooms and installed at the corners thereof, and the contaminated gas generated in the private room is cleaned and the influence of the contaminated gas on other private rooms is achieved. The present invention relates to a corner-installed air purifier that does not have any problems.

  In a restaurant, there is a tendency that a small number of people do not care about other people's eyes and want to enjoy meals and drinks, and the store is simply divided into partitions to separate rooms. As shown in FIG. 6, these private rooms 50 are exempt from the obligation to install fire alarms and sprinklers according to the Fire Service Act in each private room 50 without installing the partition 51 up to the ceiling 52. Therefore, since each private room 50 is open between the upper end of the partition 51 and the ceiling 52, it is not possible to block, for example, cigarette smoke accompanying smoking even if it can block the eyes of others.

From this point of view, it is conceivable to block the upper part of the partition with an air curtain to block the cigarette smoke from the private room. As such a technique, the following by the present applicant is known.
JP 2004-347309 A

  As shown in FIGS. 7 and 8, the air curtain device 60 of Patent Document 1 is provided on the upper side wall 62 of the rectangular non-canopy unit chamber 61 and extends from the air curtain outlet 63 in the longitudinal direction of the non-canopy unit chamber 61. The air curtain 64 is blown out to close the upper opening 65. The air curtain device 60 includes an air purifier composed of a prefilter, an electric collector and a deodorizing filter, and a blower. The air curtain device 60 purifies air sucked from the air suction port 66, and cleans the air curtain outlet 63 and the air. The cleaning air is blown out from the outlet 67. Since the amount of purified air blown out from the air outlet 67 is set to be larger than the amount of outside air drawn in by the air curtain 64, the inside of the canopy unit chamber 61 becomes a negative pressure region, and cigarette smoke, etc. Will not leak directly to the outside.

  In the air curtain device 60 of Patent Document 1 described above, the inside of the rectangular canopy unit chamber 61 becomes a negative pressure region, and the cigarette smoke does not go out when the inside of the canopy unit chamber 61 is a smoking area. The air from the air outlet 67 and the air curtain outlet 63 is convenient in that it is cleaned by an air purifier. However, in order to close the upper opening 65 of the rectangular canopy unit chamber 61 with the air curtain 64, the air curtain 64 having the same width as one side of the no-canopy unit chamber 61 is required. This requires that the width of the air curtain outlet 63 of the air curtain device 60 is substantially the same as one side of the topless unit chamber 61. Therefore, when the inside of the store is simply divided into partitions and separated into individual rooms, the air curtain device 60 having the air curtain outlets 63 with various width dimensions is required, which makes it difficult to cope with the problem.

  Therefore, the present invention has been made in view of the above circumstances, and even if the space between the upper end of the partition for making a private room and the ceiling is vacant, tobacco smoke and the like are not leaked directly from the private room together with air. In addition, it is an object to provide a corner-installed air cleaner that can easily cope with diversification of the shape of a private room.

The corner-installed air purifier according to claim 1 drives a blower to suck air from an air suction port facing the room space of the private room, and uses the air purifier to make clean air, and then the purified air is supplied to the ceiling of the private room. While blowing air from the air outlet facing the outside space, and blowing out the fan-shaped air curtain horizontally from the air curtain outlet located in the corner of the private room, the private room is divided into a living room space and a ceiling side outer space, Since the amount of air blown from the air outlet (Q1) is set to be larger (Q1> Q2) than the amount of externally entrained air (Q2) of the fan-shaped air curtain, the inside of the room space becomes a negative pressure region. Therefore, even if the space between the upper end of the partition and the ceiling of the room is open, cigarette smoke does not leak directly with air from each individual room, and the corner of the private room is installed. There is an effect that it becomes easy to cope with the diversification of the shape of.

  The corner-installed air cleaner according to claim 2 discharges sterilization ions to the clean air in the machine body by a sterilization ion generator, and the sterilization ion-containing clean air serves as an air outlet and an air curtain blower. Blow out from the exit. Therefore, in addition to the above effects, the effect of sterilization ions can be expected.

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

  FIG. 1 is a side view of a corner-installed air cleaner according to an embodiment of the present invention installed in a corner of a private room, and FIG. 2 is a diagram of the corner-installed air cleaner of FIG. 1 installed in a corner of a private room. 3 is a plan view of the corner-installed air cleaner of FIG. 1, FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3, and FIG. 5 is a bottom view of the corner-installed air cleaner of FIG. is there. In the drawing, a corner-installed air cleaner 1 includes a room 2 having one or more private rooms 5 in the partition 4 in a state where the ceiling surface 3 and the upper end 4a of the partition 4 are opened. The air curtain outlet 7 for blowing air in a horizontal direction and in a fan shape is provided in the machine body 6 installed in the machine body. The fan-like air curtain 8 from the air curtain outlet 7 divides the individual room 5 into the ceiling side outer space 9 and the living room space 10. Separately, an air suction port 11 is provided in the airframe 6 facing the living room space 10, an air outlet 12 is provided in the airframe 6 facing the outer space 9 on the ceiling side, and the air suction port 11, the air curtain outlet 7, and An air purifier 13 and a blower 14 are provided in the airframe 6 located between the air outlet 12 and the amount of air (Q1) from the air outlet 12 is changed to a fan-shaped air car. Than the amount of air emissions 8 involve from the ceiling side outer space 9 (Q2) is set to a large (Q1> Q2), it is to the room space 10 in the negative pressure area.

  In the corner-installed air purifier 1, the room 2 is divided into one or more private rooms 5 in the partition 4, and the corner 5 a of the private room 5, that is, the corner 4 of the partition 4 is installed. If the shape of the private room 5 is rectangular, there will be a total of four corners 5a in the private room 5, but any corner 5a may be used, and this installation situation may be in room 2, for example, in a restaurant. It depends on the conditions and is not limited to FIGS.

  The airframe 6 has a fan shape in which a disk-shaped box is cut into ¼, the air suction port 11 is provided in the fan-shaped bottom plate 20 of the airframe 6, and the air outlet 12 is provided in the fan-shaped upper plate 21 of the airframe 6. In addition, an air curtain outlet 7 is provided on the curved side plate 22 of the body 6. These air inlet port 11, air outlet 12 and air curtain outlet 7 are covered with punching metal so as to make air supply and exhaust uniform. And since the air curtain blower outlet 7 is comprised as an aggregate | assembly of the small hole of a punching metal over 90 degrees in the circular side plate 22 of the airframe 6, it exists in the part which becomes the main part of the fan of the airframe 6. When air is sent from the blower 14, the fan-shaped air curtain 8 is blown out from the air curtain outlet 7. The entire upper opening of 5 can be closed by airflow.

  And in this airframe 6, the said air cleaner 13 and the said air blower 14 are provided, and if the air cleaner 13 has a certain fixed cleaning performance, there will be no limitation in particular, It attaches to the air suction inlet 11 It comprises a prefilter 30 that removes relatively large particles, an electric dust collector 31 that removes fine particles that have passed through the prefilter 30, and an adsorption filter 32 that adsorbs pollutant gases such as odors.

  The blower 14 can suck the amount of air blown from the air outlet 12 (Q1), the amount of fan-shaped air curtain 8 from the air curtain outlet 7 and the amount of externally entrained air (Q2) from the air inlet port 11, and Especially, as long as it can generate the air volume and the air pressure necessary to blow out the air quantity (Q1) and the fan-shaped air curtain 8 quantity from the air outlet 12 and the air curtain outlet 7, it is particularly limited. There is no.

  Further, as shown in FIG. 4, the sterilization ion generator 33 is provided in the airframe 6 located downstream of the air cleaner 13 and upstream of the air curtain outlet 7 and the air outlet 12. . Accordingly, the sterilization ion generator 33 discharges the sterilization ions R to the clean air in the airframe 6, and the sterilization ion R-containing clean air is blown out from the air outlet 12 and the air curtain outlet 7. The effect of fungal ion R can be enjoyed.

As the sterilization ion generator 33 described above, for example, a dielectric is sandwiched between both ion generation electrodes, and an alternating current having a voltage of 1.5 KV to 3.0 KV and a frequency of 15 KHz to 2.5 KHz is applied to one of the ion generation electrodes. However, there is a configuration in which the other ion generating electrode is grounded. In this embodiment, each ion generation electrode has a structure of H ⁺ (H ₂ O) _m that is a positive ion or O ₂ ⁻ (H ₂ O) _n (m and n are integers) that is a negative ion. Things occur. These positive and negative ions constitute a sterilization ion R in a cluster shape. This sterilization ion R surrounds bacteria and viruses floating in the air, and reacts with these positive and negative cluster ions on the surface of these bacteria and viruses to generate hydroxyl radicals, OH or hydrogen peroxide H _2. O ₂ is produced, and these inactivate or kill bacteria and viruses.

  In addition, when the sterilization ion generator 33 applies, for example, a high voltage of 6.0 KV to water, the water obtains a large energy, and after the surface tension, Rayleigh splits (electrostatic atomization) one after another, and 20 nm ( It may be in a form in which ultrafine ions, which are sterilization ions R wrapped in water before and after nanometers, are generated. The ultrafine ions generated in this form last for a long time because they contain hydroxy radicals / OH and are surrounded by water, encapsulate the bacteria and viruses, and kill the bacteria and viruses by the hydroxy radicals / OH. In addition, sterilization ions R in any of the above forms can also decompose odor components in addition to bacteria and viruses.

Next, the operation of the corner-installed air cleaner 1 having the above configuration will be described.
The start switch of the corner installation type air purifier 1 is turned on, and an operation signal is sent to the blower 14, the air purifier 13, and the sterilization ion generator 33 to operate them. First, air in the living room space 10 is sucked from the air suction port 11 by driving the blower 14, and relatively large particles such as dust and ash in the sucked air are removed by the prefilter 30 of the air cleaner 13. Fine particles that could not be removed by the pre-filter 30 are removed by the electric dust collector 31, and further, odor components and harmful gases are removed by the adsorption filter 32. Note that a high-performance mechanical filter may be used instead of the electric dust collector 31.

  The suction air purified as described above is further mixed with the sterilization ions R released from the sterilization ion generator 33, and the sterilization action is immediately started. The cleaning air containing the sterilizing ions R is divided into the air blown from the air outlet 12 and the fan-shaped air curtain 8 from the air curtain outlet 7 to enjoy the effect of the sterilizing ions R. The blown air and the fan-shaped air curtain 8 are ensured in their homogeneity and directionality by a punching metal or a honeycomb commutator attached to the air blower outlet 12 and the air curtain blower outlet 7.

  The fan-shaped air curtain 8 blown out in the horizontal direction from the air curtain outlet 7 is widened to close the upper end 4a of the partition 4 forming the private room 5 in an air flow, and the private room 5 is covered with the living room space 10 and the ceiling side outer space. Divide into 9. And since the air quantity (Q1) which blows off from the air blower outlet 12 is set to be larger (Q1> Q2) than the external air volume (Q2) of the fan-shaped air curtain 8, the inside of the living room space 10 is set. Set to negative pressure range. For this reason, the air in the living room space 10 of the private room 5 does not leak directly to the other adjacent private rooms 5, and conversely, the other private rooms 5 are also in the negative pressure region. The air in 5 will not leak directly.

  Therefore, even if smoking is carried out in the private room 5, the cigarette smoke does not leak into the other private room 5, enters the airframe 6 through the air inlet 11, is removed by the air purifier 13, and is further sterilized ion R It can be sterilized and deodorized by the contained clean air to remove harmful effects such as dirt in the private room 5 caused by cigarette smoke, and other private rooms 5 can of course improve the internal environment of the whole room 2. In addition, since this corner installation type air cleaner 1 is installed in the corner part of the partition 4 which comprises the private room 5, it can respond easily also to the remodeling of the room 2, for example, a restaurant.

  As described above, the first embodiment of the present invention has been described, but the specific configuration is not limited to this, and modifications and additions within the scope not departing from the gist of the present invention, other combinations in each claim, It should be understood that this is possible as appropriate.

  In the present invention, even when the upper end of the partition for making a private room and the ceiling are open, cigarette smoke and the like are not leaked directly together with air from each private room, and it is easy to diversify and change the shape of the private room. When it is necessary to cope with this, its availability becomes extremely high.
