Description

  The present invention relates to an air purifying apparatus in which dust collecting means for collecting dust in the air is stored in a main body case, and is particularly suitable for use in a game facility such as a pachinko parlor.

  2. Description of the Related Art Conventionally, this type of air purifying device purifies ambient air by collecting dust and dirt in air taken in from an inlet, and then sending out dust from an outlet. For example, as a device suitable for a gaming facility such as a pachinko parlor, when installed on a gaming machine island in which a plurality of gaming machines are juxtaposed, an island-installed air purifier provided with a suction port facing the front of the gaming machine. A machine has already been proposed (see Patent Document 1).

  Such an air cleaner installed on an island has been configured so that the dust collection unit in the main body can be pulled out only in one direction from the suction port in order to take it out for maintenance and inspection. Generally, in pachinko parlors, there are passages on both sides of the gaming machine island. Therefore, when performing maintenance and inspection of the air cleaner installed on the island, a stepladder is placed on a passage on one side of the island, approaching the distance to touch the air cleaner, and the dust collecting unit is taken out from the suction port.

Japanese Utility Model Registration No. 3175470

  However, in the island-installed air purifier described in Patent Document 1, since the dust collection unit in the main body can be pulled out from the suction port in only one direction, the direction of maintenance and inspection with respect to the main body is limited to only one direction. It was inconvenient. In other words, when performing maintenance and inspection of the dust collection unit at a pachinko parlor, if a stepladder is mistakenly placed on the passage opposite to the suction port of the main body, move the stepladder around the gaming machine island to the opposite passage. I had to.

  In addition, Patent Document 1 discloses that, in addition to providing suction ports of an air purifier on two surfaces and providing a dust collection unit for each suction port, only one dust collection unit in the main body may be used. (Paragraph 0032). As described above, when one dust collection unit is provided for two suction ports, it may be assumed that the dust collection unit is taken out of each suction port to the outside. However, since the size and position of the suction port are determined according to the mutual position with the dust collection unit in the main body and the dust collection capacity, the degree of freedom in design is poor, and the intake and removal of the dust collection unit is also used. Design was difficult.

  The present invention has been made in view of the above-mentioned problems of the conventional technology, and the internal dust collecting means can be freely taken in and out from either of two opposing sides of the main body case. It is possible to easily perform maintenance and inspection of the dust collection means, and freely design the opening for taking in and out of the dust collection means without any restrictions on the design specifications of the suction port It is an object of the present invention to provide an air purifying device that can perform air purifying.

The gist of the present invention to achieve the above-described object lies in the inventions of the following items.

The air purifying apparatus (10) according to the above [2], wherein the contact is made in a state of being sealed by the fitting of the air purifier.

Next, an operation based on the above-described solution will be described.
According to the air cleaning device (10) according to the above [1], there are openings (14) facing two opposite sides of the main body case (11). The dust collecting means (20) in the main body case (11) can be taken in and out.

  Here, each opening (14) is separate from the air suction part (12) and the air blowing part (13) in the main body case (11), and the design specifications (conditions) such as their position and size are different. Without limitation, it can be freely designed as an independent opening. Further, the dust collecting means (20) can be freely taken in and out of each opening (14) without interfering with the suction part (12) and the blowing part (13).

  If there is a passage (work space) at, for example, both sides of the place where the air purifying device (10) is installed, it is preferable to arrange the openings (14) so that each opening (14) faces the passage. This makes it possible to approach the opening (14) from either side of the passage with respect to the air cleaning device (10). Therefore, it is possible to easily take out the dust collecting means (20) and perform maintenance and inspection without particularly worrying about the direction of the air cleaning device (10).

A lock mechanism (40) for detachably restraining the dust collecting means (20) to a predetermined storage position in the main body case (11) is provided beside each of the openings (14). . Here, each lock mechanism (40) is fixed at a fixed position beside each of the openings (14), and when one of the locks at the fixed position is released, one of the openings (14) is located. From 14), the dust collecting means (20) can be taken in and out of the main body case (11).

Therefore, the dust collecting means (20) is put in and out only by operating the lock mechanism (40) on the one opening (14) side without operating the lock mechanism (40) on the other opening (14) side. It can be restrained or released from the side opening (14). With such a lock mechanism (40), the dust collecting means (20) can be securely held at a predetermined storage position in the main body case (11), and can be easily removed.

According to the air cleaning device (10) according to the above [3], the power supply unit for supplying power to the electric precipitator (22) is disposed downstream of the flow of air in the electric precipitator (22).
In an installation place where the ratio of smokers is relatively large and the environmental load is large, such as a game facility such as a pachinko parlor, dirt easily adheres to the electric dust collector (22). If dirt adheres to the electrode contact of the power supply unit of the electrostatic precipitator (22), a phenomenon (leakage) occurs in which a high voltage propagates through the dirt and causes a problem. Therefore, by arranging the power supply unit on the downstream side of the electric precipitator (22), that is, in an area through which the clean air passes, it is possible to prevent dirt from adhering to the power supply unit as much as possible.

Further , the power supply unit includes an electrode contact (28) on the main body case (11) side and an electrode contact (24) on the electric precipitator (22), and each electrode contact (24, 28) has an uneven structure. Contact in a sealed state by the fitting of Thus, the electrode contacts (24, 28) can be reliably brought into contact without being displaced. Further, since the electrode contacts (24, 28) are not exposed to the outside when they are in contact with each other, it is possible to prevent dirt from entering.

Hereinafter, embodiments representative of the present invention will be described with reference to the drawings.
In the air cleaning device 10 according to the present embodiment, a dust collecting means 20 that collects dust and dirt in the air is housed in a main body case 11, the external air is taken into the inside to purify the air, and the cleaned air is removed. It is sent out. Hereinafter, an example in which the air purifying device 10 is installed on the gaming machine island 1 in a pachinko parlor will be described.

  As shown in FIGS. 1 to 4, in the air cleaning device 10, related parts including the dust collecting means 20 are stored in a main body case 11 formed in a substantially cubic box shape, and the gaming machine island 1 shown in FIG. It is configured in a size that can be installed as it is on the top of. Here, the gaming machine island 1 is one in which a plurality of gaming machines (pachinko machines) 2 are arranged side by side in a back and forth row in a pachinko parlor. Inside the pachinko parlor, both sides of the pachinko machine island 1 are aisles.

  The main body case 11 of the air cleaning device 10 includes a suction unit 12 that takes in air from outside, and a blowout unit 13 that sends out air that has passed through the dust collecting means 20 to outside. The body case 11 is provided with an opening 14 facing the two opposing sides separately from the suction part 12 and the blowing part 13 so that the dust collecting means 20 can be taken in and out of the body case 11 from the two sides. Have been. The opening 14 is provided in such a size that the dust collecting means 20 can be taken in and out of the suction part 12 and the blowing part 13 without interfering with the dust collecting means 20.

  As shown in FIGS. 1 and 5, the main body case 11 is formed in a cubic box shape that is long in the front-back direction, and has a rectangular bottom portion 15 and a ceiling portion 16, and support members 17 a and 17 b that support therebetween. It has a framework consisting of The front side of the framework is open as it is, and the opening is covered with an intake cover 120 to form a suction portion 12. Although not shown in the figure, the rear side of the framework is also open, and the outlet 13 is formed by covering the opening with an exhaust cover 130.

  Both side surfaces of the frame of the main body case 11 are largely opened to the side except for portions that are covered by the side ends of the front and rear covers 120 and 130, except for a portion of the opening occupied by the blower means 30 described later. Opening 14. Each opening 14 is normally closed by a maintenance cover 60, and is further covered by a side panel 50 from above the maintenance cover 60.

  The body case 11 has an outer shell formed by an intake cover 120 on the front side, an exhaust cover 130 on the rear side, a pair of side panels 50 and 50 covering both side surfaces, and a bottom part 15 and a ceiling part 16. Each component such as the ceiling 16 of the main body case 11 and the covers 120 and 130 in the suction unit 12 and the blowout unit 13 is formed of a metal such as stainless steel, for example. With such a metal material, dirt does not become noticeable unless particularly painted.

  In the suction portion 12, external air is taken into the main body case 11 through many holes provided in the intake cover 120. On the other hand, in the blowing section 13, the cleaned air is sent out of the main body case 11 through a number of holes provided in the exhaust cover 130. Here, in the illustrated example (see FIG. 13), the holes are formed by honeycomb punching in which hexagonal holes are densely arranged in front, rear, left and right, and can have a higher aperture ratio in the same area than a round hole.

  The size (opening diameter) of each hole in the intake cover 120 and the exhaust cover 130 is set smaller than the diameter of a game ball that is a game medium of the gaming machine. As a result, it is possible to prevent a situation in which a game ball dropped from the game ball delivery facility in the pachinko parlor enters from the suction unit 12 or the blowing unit 13 or a trouble due to mischief. The specific form of the hole is not limited to the honeycomb punching, but may be provided, for example, so that slits are arranged. In any case, the hole is preferably set smaller than the diameter of the game ball.

  The suction portion 12 is provided so as to include not only the front surface of the main body case 11 but also a part of the front end side on both side surfaces. That is, in addition to the front wall facing the front opening of the frame of main body case 11, intake cover 120 includes both side walls connected to both sides thereof and forming front end sides of both side surfaces of main body case 11. Due to the intake cover 120, the front wall forming the front surface of the suction portion 12 is separated from the air suction side front surface of the dust collecting means 20, which will be described later, by at least the distance between the front and rear widths of both side walls. Thereby, a part of the side surface of the main body case 11 also serves as the suction portion 12, and a relatively large space is secured between the front surface of the suction portion 12 and the front surface of the dust collecting means 20 on the air suction side.

  The corners between the front wall and both side walls of the intake cover 120 are formed so as to be able to be punched even at the rounded portion by simply forming a rounded cross-sectional shape without being bent at a right angle. If the front wall and both side walls of the intake cover 120 are bent at a right angle, it is difficult to provide a hole in the corner in order to maintain strength, and the suction part 12 is connected to the front surface at the corner. It will be divided into sides. Note that the same applies to the configuration of the exhaust cover 130 surrounding the blowout section 13.

  In the present air purifying apparatus 10, the strength of the main body case 11 is weakened by the provision of the large openings 14 for inserting and removing the dust collecting means 20 on both side surfaces of the main body case 11, but the intake cover 120 and the exhaust cover 130 It is reinforced by. That is, the intake cover 120 and the exhaust cover 130 become planar supports separately from the support members 17a and 17b. As for the reinforcement of the main body case 11, only the intake cover 120 is sufficient. With the intake cover 120, a region for taking in air from the outside in a wide range can be secured, and the strength of the main body case 11 can be maintained.

  More specifically, the suction part 12 is connected to a front part 16 a, which can be separated as a part of the ceiling part 16, at the front wall and both side walls of the intake cover 120, and is attached to the front side of the frame of the main body case 11. It is configured as a unit to perform. A reinforcing frame 121 is fixed along the lower edge of the front wall and both side walls of the intake cover 120 so as to match the peripheral edge of the front portion 15a of the bottom portion 15. In addition, an intake port 12 a in which narrow slits are arranged as a part of the suction section 12 is separately provided in the front section 16 a of the ceiling section 16. In the reinforcing frame 121, a handle portion 122 serving as a clue for carrying is recessed at a portion extending upward from the front center.

  Similarly, the blowout unit 13 is a unit in which the rear end wall of the exhaust cover 130 and the upper end edges of both side walls are connected to a rear part 16 b which can be separated as a part of the ceiling part 16, and is attached later to the rear side of the frame of the main body case 11. Is configured as A reinforcing frame 131 is fixed along the lower edge of the front wall and both side walls of the exhaust cover 130 so as to match the peripheral edge of the rear portion 15b of the bottom portion 15. In the reinforcing frame 131, a handle portion 132, which is paired with the handle portion 122, is recessed at a portion extending upward from the front center.

  As shown in FIG. 1, in a main body case 11 of the air cleaning device 10, a pre-filter 21 and an electric precipitator 22 forming a dust collecting means 20 are arranged in order from a suction part 12 on a front side to a blowing part 13 on a rear side. , And a blowing means 30 are housed therein. The dust collecting means 20 according to the present embodiment basically has a pre-filter 21 and an electric dust collector 22. Here, the pre-filter 21 and the electrostatic precipitator 22 can be put in and out of the main body case 11 through the openings 14 on both sides of the main body case 11 with a side panel 50 and the like to be described later removed.

  The blower 30 is fixed at a position facing the rear opening in the internal space in the main body case 11. The internal space in front of the blowing means 30 is divided into a storage space in which the dust collecting means 20 is detachable facing the front opening and an empty space extending downstream and reaching the front face of the blowing means 30. The front surface of the pre-filter 21 is the front surface of the dust collector 20 on the air suction side, and the rear surface of the electric dust collector 22 is the rear surface of the dust collector 20 on the air discharge side. The empty space in front of the blower 30 is a space for preventing a pressure loss when the blower 30 is driven, and also for taking out a fan 32 described later, which is a part of the blower 30, from the opening 14. Is required.

  The pre-filter 21 captures relatively large dust when the air taken in from the suction part 12 passes first. Here, the dust broadly includes cotton dust, lint, and other particles to be removed. The pre-filter 21 is configured by attaching a filter material 211 obtained by repeatedly bending a metal net into a pleated shape on a frame-shaped mounting frame 210, and stacking a mesh-like sheet made of nonwoven fabric or resin on the inside thereof. In the pre-filter 21, it is necessary to periodically clean the filter material 211 in order to prevent clogging, and it is necessary to replace the pre-filter 21 with a new one when the sheet is deteriorated.

  The opening area of the mounting frame 210 of the pre-filter 21 corresponds to the area of the dust collection means 20 on the air suction side front. The opening area of the suction part 12 is set to be at least equal to or larger than the opening area of the mounting frame 210 of the pre-filter 21. Here, the opening area of the suction section 12 is the sum of the areas of the holes in the intake cover 120. As the opening area of the suction section 12 is larger than the opening area of the mounting frame 210, the air suction efficiency of the suction section 12 can be increased.

  In addition, the opening area of the suction part 12 is set smaller than the surface area of the filter material 211 itself, thereby improving the dust collecting function. With respect to the opening area of the suction section 12, the intake port 12a does not need to be considered. Further, the opening area of the blowout portion 13 is the sum of the areas of the respective holes in the exhaust cover 130, and the opening area of the blowout portion 13 is a design item that can be set as appropriate.

  The electric precipitator 22 collects the relatively small dust that is still contained in the air that has passed through the pre-filter 21 by collecting charges. The electric dust collector 22 charges (ionizes) the dust in the incoming air by discharging, and adsorbs and collects the charged dust. The configuration of the electrostatic precipitator 22 itself is well known, and a detailed description thereof is omitted. However, a large number of discharge or dust collecting electrode plates 221 are arranged in a frame-shaped case 220 having open front and rear surfaces. Like the pre-filter 21, it is configured as a detachable unit at a predetermined storage position in the main body case 11. The electric dust collector 22 also requires regular cleaning and maintenance including replacement of parts to prevent clogging.

The storage space of the dust collecting means 20 in the main body case 11 is open on both sides of the main body case 11 as it is, and serves as the opening 14 which is taken in and out at the time of maintenance and inspection of the dust collecting means 20. Here, the storage space is divided into a storage position of the pre-filter 21 and a storage position of the electric precipitator 22.
The storage position of the pre-filter 21 is at the forefront along the front opening of the frame of the main body case 11, and is partitioned by fixing the base 15 c on the bottom surface 15. The base 15 c extends between the openings 14, and its front and rear widths match the depth of the mounting frame 210 of the prefilter 21.

  Immediately in front of the front edge of the base 15c, the support member 17a is provided upright. A flange for preventing the pre-filter 21 from being shifted toward the storage position of the electric dust collector 22 is provided at the rear edge of the base 15c. 15d is erected. Further, a lock mechanism 40 for detachably restraining the dust collecting means 20 at the storage position is provided at both ends of the base 15c, that is, beside each opening 14. The details of the lock mechanism 40 will be described later. In addition, at the storage position of the pre-filter 21, a space may be provided in which the depth and depth of the pleats (folds) of the filter material 211 can be adjusted.

  On the other hand, the storage position of the electrostatic precipitator 22 is from immediately behind the storage position of the pre-filter 21 to just before the empty space in front of the blowing means 30. The rear end of the storage position of the electrostatic precipitator 22 is defined by the end surface of the base 15e mounted on the bottom surface 15 in the empty space and the support member 17b. The storage position of the electrostatic precipitator 22 extends over the entire width between the openings 14, and the front and rear widths thereof match the depth of the case 220 of the electric precipitator 22.

  A notch 16 c for positioning is provided on the inner surface side of the ceiling 16 located above the storage position of the electric dust collector 22 so as to extend over the entire width between the openings 14. When the notch 16 c is aligned with the ridge rail 222 provided along the rear end edge of the case 220, when the electric dust collector 22 is housed in the main body case 11 from each opening 14, the notch 16 c This prevents the front and rear from being reversed. Both ends of the rail 222 are tapered toward the center so as to be easily inserted from the ends of the notches 16c.

  A handle 223 and a leg 224 are provided on both side surfaces of the case 220 of the electric dust collector 22. By gripping the handle 223, the work of taking in and out of the electric dust collector 22 and carrying the electric dust collector 22 are facilitated. Further, the both ends of the handle 223 and the pair of legs 224 allow the case 220 to be placed without directly contacting both sides of the case 220 with the floor. If a slide rail is provided on the bottom portion 15 at the storage position of the electrostatic precipitator 22 so as to smoothly slide the electric precipitator 22 in both directions, the operation of taking in and out the heavy electric dust collector 22 becomes easy. .

  The pre-filter 21 and the electric precipitator 22 which are the dust collecting means 20 can be put in and out through the opening 14 opened at the side where the storage position in the main body case 11 is opened as it is. Here, the opening 14 is formed in a size that allows not only the dust collecting means 20 but also all or a part of the blowing means 30 to be taken in and out. That is, in addition to the openings at the storage positions of the pre-filter 21 and the electrostatic precipitator 22, the opening 14 also includes an opening in an empty space in front of the blower 30. Can be put in and out. Further, by forming the entire blowing means 30 so as to be detachable in the main body case 11, openings on both sides in the storage space of the blowing means 30 may be included as the openings 14.

  As shown in FIGS. 7 to 10, a power supply unit for supplying electric power to the electrostatic precipitator 22 is disposed downstream of the flow of air in the electric precipitator 22. In the electrostatic precipitator 22, the front opening of the case 220 is on the upstream side facing the pre-filter 21, and the rear opening of the case 220 is on the downstream side facing the blowing means 30. It is provided. The power supply unit includes an electrode contact 24 on the electric precipitator 22 side and an electrode contact 28 on the main body case 11 side. Each of the electrode contacts 24 and 28 is configured to contact each other in a sealed state by fitting of the concavo-convex structure.

  That is, as shown in FIG. 7, a pair of engaging recesses 23, 23 arranged on both sides are formed at a lower end and an upper end surrounding the rear opening in the case 220 of the electrostatic precipitator 22, respectively. 23, a flat plate-shaped electrode contact 24 is provided at the rear end face. Here, both sides of the engagement concave portion 23 are tapered surfaces inclined toward the rear end surface portion. Each electrode contact 24 is formed of a conductive material such as a metal such as stainless steel or a conductive plastic.

  On the other hand, a pair of engaging projections 27, 27 which can protrude and retract in a direction orthogonal to the end surface, are formed on the end surface of the base 15e which defines the rear end of the storage position of the electric dust collector 22 in the main body case 11. Is provided. Although not shown, a pair of engaging projections 27 are also provided in the main body case 11 near the inside of the blowing section 13 so as to be opposed to the respective electrode contacts 24 on the upper side of the electrostatic precipitator 22. Is possible.

  As shown in FIG. 10, each engaging projection 27 is supported by a support bracket 25 fixed in the main body case 11 via a movable shaft 26 so as to be able to protrude and retract. Here, each engaging projection 27 is constantly urged in a projecting direction by an urging means such as a spring (not shown). A leaf spring-shaped electrode contact 28 obtained by bending a metal plate such as stainless steel is provided on the distal end surface of each engagement projection 27. Here, both sides of the engagement convex portion 27 are tapered surfaces inclined toward the distal end surface portion. Further, the electrode contact 28 can be displaced in the same direction as the direction in which the engaging projection 27 protrudes and retracts due to the elasticity of the leaf spring itself.

  Regarding the concavo-convex structure of the electrode contact 24 on the electric precipitator 22 side and the electrode contact 28 on the main body case 11 side, in the present embodiment, the electrode contact 24 on the electric precipitator 22 side is made concave, and the electrode contact 28 on the main body case 11 side is formed. The reason for this is that it is easier to block from the flow of air when it is sealed by fitting of the uneven structure. However, conversely, as an embodiment, the electrode contacts 24 on the electric precipitator 22 side may be made convex, and the electrode contacts 28 on the main body case 11 side may be made concave.

  As shown in FIGS. 11 and 12, the lock mechanism 40 beside each opening 14 of the main body case 11 is constituted by a slide lock type stopper. Each lock mechanism 40 is fixed to both ends of the base table 15c (see FIG. 5). FIG. 11A is a perspective view when the lock mechanism 40 is restrained, and FIG. 11B is a perspective view of the entire device when the lock mechanism 40 is restrained. FIG. 12A is a perspective view of the lock mechanism 40 when the restraint is released, and FIG. 12B is a perspective view of the entire device when the lock mechanism 40 is released.

  Each locking mechanism 40 restrains the pre-filter 21 and the electric dust collector 22 as the dust collecting means 20 at the same time at the storage position in the main body case 11 (fixed so as not to come off). In the lock mechanism 40, by releasing one of the constraints, the pre-filter 21 and the electric dust collector 22 (the dust collecting means 20) can be put in and out of the main body case 11 through the opening 14 on the one side. Each lock mechanism 40 is fixed to both ends of the base 15c (see FIG. 5) located at the storage position of the pre-filter 21 in the main body case 11.

  As shown in FIGS. 11A and 12A, the lock mechanism 40 includes a case-shaped placket 41 and a lock pin 42 which is supported by the placket 41 and slides in the left-right direction (axial direction). It is configured. In the middle of the lock pin 42, an operation knob 43 is integrally protruded via an engagement shaft 43a. The placket 41 is provided with engaged grooves 41a to 41c into which the engaging shaft 43a is movably fitted in accordance with the operation of the knob 43 for sliding the lock pin 42.

  As shown in FIGS. 11A and 11B, in a restrained state in which one end of the lock pin 42 projects rightward from the placket 41, the engagement shaft 43a of the knob 43 is above the one end of the engaged groove 41c. Projecting to In this restrained state, one end of the lock pin 42 is engaged with the front of the electric precipitator 22, so that the electric precipitator 22 cannot be taken out of the opening 14, and the knob 43 is placed in front of the pre-filter 21. Because of the engagement, the pre-filter 21 cannot be removed from the opening 14.

  When the knob 43 in the restrained state is moved from one end of the engaged groove 41c to the other end, the lock pin 42 slides leftward in the axial direction, and one end of the lock pin 42 enters the placket 41. Further, when the knob 43 is tilted forward from the other end of the engaged groove 41c, the lock pin 42 rotates around the axis, and the engaging shaft 43a of the knob 43 is engaged via the engaged groove 41b. The engagement is released with the lower end of the groove 41a.

  As shown in FIGS. 12 (a) and 12 (b), when one end of the lock pin 42 is inserted into the bracket 41 and the other end of the lock pin 42 projects leftward from the bracket 41, the knob is released. The engagement shaft 43a of 43 projects forward from the lower end of the engaged groove 41a. In this constrained state, one end of the lock pin 42 comes off from the front of the electric precipitator 22, so that the electric precipitator 22 can be taken out from the opening 14, and the knob 43 comes off from the front of the pre-filter 21. The filter 21 can also be taken out of the opening 14. Further, as shown in FIG. 13, the knob 43 projects forward from the opening 14, so that a side panel 50 or the like described later cannot be mounted.

  Further, as shown in FIG. 1, in the main body case 11, on the downstream side of the electric precipitator 22, the air blowing means 30 is housed in the above-mentioned empty space. The blower means 30 is configured to take in air from the suction portion 12 of the main body case 11 by rotating the fan 32, pass the air through the pre-filter 21 and the electric dust collector 22 in order, and then send the air to the outside from the blowout portion 13 or the like. It is. The blowing means 30 includes a fan 32 for blowing air, an electric motor (not shown) for rotating the fan 32, and the like in a box-shaped housing 31, and is configured as a unit.

  Specifically, for example, a turbo fan having a high static pressure and a large air volume is employed as the fan 32. The turbofan is configured to draw air spirally from the radially inner side facing the upstream side and discharge the air radially outward over the entire circumference. The fan 32 can be removed from the housing 31 and can be taken in and out through the openings 14. Here, the housing 31 is fixed in the main body case 11 in principle, but can be taken out by removing screws and the like.

Both sides of the housing 31 of the blowing means 30 are continuous with the respective openings 14 and also serve as side surfaces of the main body case 11. Thereby, the weight of the entire air cleaning device 10 can be reduced, and the cost can be reduced.
In the main body case 11, the clean air discharged from the entire circumference of the fan 32 is mainly discharged from the outlet 13 mainly covered with the exhaust cover 130 and the outlet 52 provided on the side panel 50 described below. The air is sent out (main) to the air outlets 13a and 13b provided in the roof portion 19, and is sent out (sub).

  The exhaust side of the blowing means 30 communicates with the blowout portion 13. As shown in FIG. 1, the inside of the ceiling portion 16 where the outer periphery of the fan 32 opposes the upper surface opening of the housing 31. An exhaust space 18 communicating with the air vent 18a is provided. At a predetermined location on the ceiling 16 located above the exhaust space 18, a roof 19 projecting upward by a predetermined height is provided. On the front and rear end surfaces of the roof portion 19, air outlets 13a and 13b are provided separately from the blowout portion 13, respectively. The roof portion 19 and the front and rear air outlets 13a and 13b serve as a path changing portion for changing the upward flow of the air discharged from the upper surface opening of the housing 31 also in the axial direction of the turbo fan (front and rear direction) as much as possible. Has become.

  In FIG. 1, each opening 14 in the main body case 11 is normally closed with the maintenance cover 60 as described above, and is further covered by the side panel 50 from above the maintenance cover 60. The maintenance cover 60 is made of a rectangular plate substantially matching the size of the opening 14, and is configured to be detachable from the opening 14 of the main body case 11 without tools. That is, at the lower end edge of the maintenance cover 60, the insertion piece 61 is provided, which is detachably engaged with the engaging groove at the lower end side of the opening 14. Above the maintenance cover 60, a well-known one-touch lock mechanism 62 that can be detachably fixed to the upper end side of the opening 14 is provided.

  The side panel 50 is formed of a parallelogram plate having a size such that the side surface of the housing 31 of the blowing means 30 is aligned with the opening 14 and also covers a part of both side walls of the front and rear covers 120 and 130. Similarly to the maintenance cover 60, the side panel 50 is configured to be detachable from the opening 14 of the main body case 11 without tools. That is, the lower edge of the side panel 50 is provided with a locking means such as a magnet that is removably locked to the lower end of the opening 14. The upper edge of the side panel 50 is connected to a locking piece 51 along the side edge of the ceiling 16, and the upper side of the side panel 50 is attached to and detached from the upper end of the opening 14. A well-known one-touch locking mechanism (not shown) that can be fixed as much as possible may be appropriately adopted.

  The side panel 50 according to the present embodiment can be removed from the main body case 11 when it is opened, but may be configured to be openable and closable in a state where a part such as one edge of the side panel 50 is connected to the main body case 11. . In any case, by opening (removing) the side panel 50 and the maintenance cover 60, the pre-filter 21 and the electric dust collector 22, which are the dust collecting means 20, and the fan 32 of the air blowing means 30 are moved from the inside of the main body case 11 to the outside. It can be taken out.

  At one end of the upper end of the side panel 50, a horizontally long outlet 52 is opened separately from the outlets 13 a and 13 b of the outlet 13 and the roof 19. The air outlet 52 is provided with a flap 53 whose upper edge is pivoted outward with the lower edge as an axis to adjust the opening / closing angle, so that the air blowing direction can be adjusted to some extent. .

Next, the operation of the present air cleaning device 10 will be described.
As shown in FIG. 15, the air purifying apparatus 10 is installed above the gaming machine island 1 in a pachinko parlor. When installing the air purifying apparatus 10, the gaming machine island 1 does not need to be particularly remodeled, and only the independently provided air purifying apparatus 10 is mounted on the existing gaming machine island 1 and attached. The air purifying device 10 can be installed at any location on the gaming machine island 1 according to the environmental design such as the direction of air circulation in the pachinko parlor.

  The body case 11 of the air purifying device 10 is mounted such that the openings 14 on both sides thereof face the passages on both sides of the gaming machine island 1, respectively. In addition, in the gaming machine island dedicated to one side in which the gaming machines 2 are arranged in a line along the wall surface, when installing the air cleaning device 10, it is not necessary to particularly distinguish each opening 14 of the main body case 11, and in the pachinko parlor. In consideration of only the environmental design, it suffices that either of the openings 14 be directed to the front passage side, and the degree of freedom of installation of the air cleaning device 10 is improved.

  The main body case 11 is formed in a cubic box shape, and a suction portion 12 is provided on a front side, and a blowout portion 13 is provided on a rear side facing the front side. Openings 14 are provided on both side surfaces substantially orthogonal to the front and rear surfaces of the main body case 11. According to such a configuration, the function can be clearly distinguished for each surface of the main body case 11 so that it is easy to understand, and the direction of disposition at the installation location can be easily determined. That is, it is only necessary to arrange both side surfaces (openings 14) of the main body case 11 so as to face the passage, and it is possible to secure a work space on the passage when the dust collecting means 20 described later is taken in and out.

  In FIG. 15, a broken arrow indicates a flow in which air including tobacco smoke and the like rising from the vicinity of the gaming machine 2 is taken into the air purifying device 10 installed on the gaming machine island 1. In addition, solid arrows indicate flows in which the air purified by the air cleaning device 10 is exhausted to the outside. Since pachinko parlors often smoke, the air tends to become dirty due to cigarette smoke or the like. By purifying the air with the air purifier 10, the pachinko parlor can be maintained in a comfortable environment.

  When the air purifying device 10 operates, the fan 32 of the blowing means 30 rotates, and external air is taken in from the suction part 12 of the main body case 11. The outside air is also taken in supplementarily from the suction port 12 and the air inlet 12 a in the ceiling 16. In the air flow in the main body case 11, relatively large dust is first collected by the pre-filter 21, and then small dust is also electrically collected by the electric dust collector 22, and a certain degree of deodorization is also performed. The air thus purified is discharged to the outside from the outlet 13 and the outlets 13a and 13b before and after the roof 19, in addition to the outlet 52 in the side panel 50.

  In a pachinko parlor, a player often smokes during a game, and the air purifying device 10 used in such an environment is required to have higher performance than a general home air purifier. With respect to such performance, a specific relationship between the opening area of the suction part 12 and the area of the dust suction means 20 on the air suction side front is also important. As described above, the opening area of the suction section 12 is the sum of the areas of the holes in the intake cover 120, and the area on the air suction side front is the opening area of the mounting frame 210 of the prefilter 21. Here, as the opening area of the suction section 12 is larger than the opening area of the mounting frame 210, the air suction efficiency of the suction section 12 can be increased.

  As can be seen from FIG. 1, the opening area of the mounting frame 210 of the pre-filter 21 is substantially equal to the area of the front wall of the intake cover 120 forming the front surface of the suction section 12. Therefore, by increasing the distance from the front wall of the intake cover 120 to the pre-filter 21 and adding both side walls of the intake cover 120 to the suction portion 12, even if the area of the portion other than the hole in the intake cover 120 is subtracted, the suction portion 12 can be set to be larger than the opening area of the pre-filter 21.

  In other words, not only the front surface of the main body case 11 but also a part of the front end of the side surface is formed as the suction portion 12. This makes it possible to increase the amount of air taken into the main body case 11 as compared with the case where the suction portion 12 is only the front surface of the main body case 11 that matches the size of the mounting frame 210, and improves the dust collecting function. Can be done.

  If only the front surface of the main body case 11 is formed as a suction portion, the flow of air reaching the front surface of the pre-filter 21 tends to be biased toward the center of the mounting frame 210. On the other hand, like the suction portion 12 of the present embodiment, not only the front surface of the main body case 11 but also the front end side of the side surface is formed as a continuous suction portion with the front surface, so that air is also supplied near both ends of the mounting frame 210. It can be passed all over. This makes it possible to use the entire area of the pre-filter 21 evenly, and it is also possible to prevent the filter material 211 from becoming uneven.

  Further, in the present embodiment, since a turbo fan is employed as the fan 32 of the blowing means 30, the restriction on the blowing direction is reduced as compared with other fans. Therefore, the air discharged from the blowing means 30 is sent not only to the blowout portion 13 on the rear surface side of the main body case 11 but also to the front and rear upper portions of the main body case 11 from the front and rear blowout ports 13a and 13b of the roof portion 19, Further, it is also possible to send the air from the outlet 52 of the side panel 50 to both sides of the main body case 11. In this manner, air can be blown in multiple directions regardless of a movable object such as a louver, and the risk of failure is reduced.

  In an environment such as a pachinko parlor, maintenance and inspection such as cleaning of the dust collecting means 20 and replacement of parts in the air cleaning device 10 are required at high frequency. As shown in FIG. 14, according to the present air cleaning device 10, there are openings 14 facing two opposite sides of the main body case 11, and dust collection in the main body case 11 can be performed from any of the openings 14. The means 20 can be moved in and out. Here, each of the openings 14 is separate from the suction portion 12 and the blowout portion 13 of the main body case 11, and is free as an independent opening without being limited by design specifications (conditions) such as their positions and sizes. Can be designed. Further, the dust collecting means 20 can be freely taken in and out of each opening 14 without interfering with the suction part 12 and the blowing part 13.

  The air purifying device 10 is arranged on the gaming machine island 1 such that the openings 14 face the passages as described above. Thereby, it becomes possible to approach the opening 14 from either side of the passage with respect to the air cleaning device 10. Therefore, the dust collecting means 20 can be easily taken out without any particular concern about the directionality with respect to the air cleaning device 10, and the maintenance and inspection work can be performed efficiently. Therefore, the air flow (air volume) in the air cleaning device 10 can always be kept in an optimum state, and not only the dust collection performance can be maintained, but also the load on the fan 32 and the power cost can be reduced, and a failure can be prevented. be able to.

  The dust collecting means 20 is a pre-filter 21 and an electric dust collector 22 in the present embodiment, but each is configured as a unit. Thus, the pre-filter 21 and the electrostatic precipitator 22 can be easily taken in and out of each opening 14 by simply attaching / detaching (putting-in / out) the unit to / from the main body case 11. In addition to the dust collecting means 20, only the fins 32 of the air blowing means 30 can be removed from the housing 31 and taken in and out of each opening. Of course, you may make it easy to put the whole blowing means 30 in and out of each opening part 14.

  Each opening 14 in the main body case 11 is normally closed by the maintenance cover 60, and is further covered by the side panel 50 from above the maintenance cover 60. Thereby, when the dust collecting means 20 in the main body case 11 is not taken in or out, the opening 14 can be closed to conceal the internal structure of the dust collecting means 20 and the air blowing means 30 and the like. You may comprise so that it may be closed.

  The maintenance cover 60 is easily attached by the lock mechanism 62 so as to close the opening 14 without using a tool or the like in a state where the insertion piece 61 at the lower end edge thereof is locked to the lower end side of the opening 14. Can be. Further, the side panel 50 also includes the opening 14 without using a tool or the like by a lock mechanism (not shown) in a state where the locking piece 51 at the upper end edge is along the side edge of the ceiling 16. It can be easily mounted so as to cover the side surface.

  The side panel 50 according to the present embodiment can be removed from the main body case 11 when it is opened, but may be configured to be openable and closable in a state where a part such as one edge of the side panel 50 is connected to the main body case 11. . In any case, by opening (removing) the side panel 50 and the maintenance cover 60, the pre-filter 21 and the electric dust collector 22, which are the dust collecting means 20, and the fan 32 of the air blowing means 30 are moved from the inside of the main body case 11 to the outside. Can be taken out.

  In addition, the side panel 50 forms a main part of the outer periphery of the main body case 11, and not only closes the opening 14 but also has a decorative property, so that the design of the appearance of the air cleaning device 10 can be enhanced. That is, in addition to the shape of the side panel 50, it is preferable to devise the pattern and material of the outer surface. As for the material of the side panel 50, by adopting a material whose weight per unit is lighter than the material forming the main body case 11, not only the weight of the air cleaning device 10 as a whole but also the workability at the time of attaching and detaching is improved. Can be improved.

  In the main body case 11, the pre-filter 21 and the electrostatic precipitator 22 are stored in respective storage positions. However, the pre-filters 21 and the electric precipitators 22 are fixed so as not to be inadvertently moved by the lock mechanisms 40 beside the respective openings 14. Here, when one of the lock mechanisms 40 is released from the restraint, the pre-filter 21 and the electrostatic precipitator 22 can be put in and out of the main body case 11 through the opening 14 on the one side. Therefore, the lock mechanism 40 on the other opening 14 side is not operated, and only the operation of the lock mechanism 40 on the one opening 14 side restrains or releases the restraint from the opening 14 on the side where the dust collecting means 20 is taken in and out. can do.

  With this lock mechanism 40, the pre-filter 21 and the electric dust collector 22 can be securely held at the respective storage positions in the main body case 11, and can be easily removed. Safety is improved. In particular, according to the lock mechanism 40 according to the present embodiment, the pre-filter 21 and the electrostatic precipitator 22 can be simultaneously restrained or released by a series of operations. Such a lock mechanism 40 is composed of a slide lock type stopper, has a simple configuration, does not require power, and can be easily manually operated.

  As shown in FIGS. 11A and 11B, when the lock mechanism 40 is in the restrained state, one end of the lock pin 42 projects rightward from the placket 41 and engages in front of the electric dust collector 22. Therefore, the electric precipitator 22 cannot be taken out of the opening 14. Further, the knob 43 protrudes upward from one end of the engaged groove 41 c of the placket 41 and is engaged in front of the pre-filter 21, so that the pre-filter 21 cannot be taken out from the opening 14.

  When the electric dust collector 22 and the like are taken in and out of the main body case 11, the knob 43 is moved from one end of the engaged groove 41c to the other end, and the lock pin 42 is slid leftward in the axial direction so that one end is inserted into the placket 41. Immerse. Further, as shown in FIGS. 12A and 12B, when the knob 43 is tilted forward from the other end of the engaged groove 41c, the knob 43 moves to the lower end of the engaged groove 41a via the engaged groove 41b. . Thereby, the restraint of the pre-filter 21 and the electrostatic precipitator 22 can be simultaneously released only by a series of operations of the knob 43. Furthermore, when the lock mechanism 40 is in the restraint release state, as described above, since the knob 43 projects forward from the opening 14, the maintenance cover 60 and the side panel 50 cannot be mounted.

  When the ratio of smokers is relatively large and the environmental load is large as in a pachinko parlor, dirt is likely to adhere to the electric dust collector 22 as well. If dirt adheres to the electrode contacts 24 and 28 of the power supply unit that supplies power to the electrostatic precipitator 22, a phenomenon (leakage) occurs in which high voltage propagates through the dirt and causes a problem. In order to solve such a problem, it is important to prevent dirt from adhering to the electrode contacts 24 and 28 as much as possible.

  Therefore, in the air cleaning device 10, the electrode contact 24 on the electric precipitator 22 side and the electrode contact 28 on the main body case 11, which constitute the power supply unit, are connected to the downstream side of the air flow in the electric precipitator 22, that is, the rear surface of the case 220. It is arranged so as to face the opening. Accordingly, it is possible to prevent dirt from adhering to the electrode contacts 24 and 28 as much as possible, not only to prevent the leakage due to the leak, but also to reduce the cleaning time of the electrode contacts 24 and 28 and to maintain the power supply unit easily. Is improved.

  As shown in FIGS. 9 and 10, the electrode contacts 24 and 28 come into contact with each other in a sealed state by the engagement of the concave and convex structure of the engaging concave portion 23 and the engaging convex portion 27. Thereby, the sealing effect is enhanced by increasing the contact area other than the electrode contacts 24 and 28, and the electrode contacts 24 and 28 can be surely contacted without displacement. Further, since the electrode contacts 24 and 28 are not exposed to the outside when they are in contact with each other, it is possible to prevent dirt from entering.

  When the electric precipitator 22 is housed in the main body case 11, the engaging projection 27 on the main body case 11 is fitted into the engaging recess 23 on the dust collection unit side. At this time, the electrode contact 28 in the engagement projection 27 and the electrode contact 24 in the engagement recess 23 come into contact with each other. When the electric dust collector 22 is started to be removed from the inside of the main body case 11 from such a state, the engaging concave portion 23 of the electric dust collector 22 comes off while moving laterally from a position where it engages with the engaging convex portion 27 of the main body case 11.

  Conversely, when the electric dust collector 22 is removed and the accommodating projection 27 on the main body case 11 side is pushed into the corner of the case 220 of the electric dust collector 22, When the concave portion 23 moves to a position where it matches, the engaging convex portion 27 fits into the engaging concave portion 23. As a result, the electrode contacts 28 on the engagement projections 27 come into contact with the electrode contacts 28 on the engagement recesses 23. When the electric dust collector 22 is stored, the electrode contacts 24 and 28 are positioned so as to be in contact with each other by the lock mechanism 40 in the opening 14 on the opposite side.

Here, the opening area of the dust collecting means 20 on the air suction side front surface specifically corresponds to the opening area of the mounting frame 210 of the pre-filter 21.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention, the present invention is not limited thereto. Included in the invention. For example, the air purifying device 10 can be used not only in pachinko parlors but also in other game facilities or in various other indoor facilities. In addition, the main body case 11 is not limited to a substantially cubic box shape, and may have, for example, a polygonal shape or a cylindrical shape as long as there are outer walls facing two opposite sides.

  Further, the configuration of the dust collecting means 20 is merely an example. If a deodorizing filter, a photocatalyst unit, and a negative ion generator are added in addition to the pre-filter 21 and the electric dust collector 22, further deodorizing treatment can be performed by the deodorizing filter and the photocatalytic unit. The disinfection treatment can be performed, the negative ion addition treatment can be performed by the negative ion generator, and the deodorizing and disinfecting effects of the air can be enhanced. Here, it goes without saying that the deodorizing filter, the photocatalyst unit, and the negative ion generator, which constitute the dust collecting means 20, are also configured to be able to be taken in and out of the respective openings 14.

  The air purifying apparatus according to the present invention can be widely used in various other facilities besides a game facility such as a pachinko parlor.
