Description

  The present invention relates to an ion shielding space constituting apparatus capable of shielding a space by releasing an ion curtain composed of ion wind.

  Conventionally, when a shielded space such as a smoking space is formed, the space is physically partitioned using a partition made of glass, plate, resin, etc. An air curtain system is also used in which a film-like air flow is created by wind pressure, and foreign substances are prevented from moving in and out of the shielding space by this air flow.

  More recently, as an alternative to the air curtain method, there is an ion shielding space constituting device that forms an ion curtain by ion wind and shields the space, as described in Patent Document 1. In this ion shielding space constituting apparatus, an ion wind unit is installed on the ceiling, and an ion curtain is formed from the outlet to the floor side. This ion curtain can suppress Brownian motion by electrically neutralizing dust, bacteria, odor components, smoke particles, and the like passing through the ion curtain. As a result, these particles and the like fall together with the flow of the ion curtain. Therefore, if a local exhaust device is installed on the floor side, the dust that has fallen can be efficiently discharged, and a clean shielding space can be formed.

In particular, since the Health Promotion Act was enforced, facility managers such as schools, gymnasiums, hospitals, theaters, viewing halls, gathering halls, exhibition halls, department stores, offices, government facilities, restaurants, etc. In order to prevent passive smoking, the need to install smoking spaces is increasing. As means for securing this smoking space, an ion shielding space constituting device is used.

  According to the ion shielding space constituting apparatus of the present invention, it is possible to easily perform construction while realizing space saving of the apparatus itself, and to achieve an excellent effect that an ion shielding space can be efficiently secured.

  Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an ion shielding space constituting apparatus 1 according to the first embodiment of the present invention. The ion shielding space constituting apparatus 1 includes an ion curtain device 10, a first guide plate 12, a second guide plate 14, and a reflecting plate 16. The ion shielding space constituting apparatus 1 is installed in a predetermined space including four surfaces of the first inner wall 20, the second inner wall 22, the ceiling 24, and the floor 26 of the facility. The first inner wall 20 and the second inner wall 22 are at right angles to each other, and a facility corner (corner) K1 is formed at a location where they abut each other.

  The ion curtain device 10 needs to be installed at one corner of a predetermined space to be shielded by the ion curtain. Here, the ion curtain device 10 is installed at the opposite corner K2 located at the diagonal of the facility corner K1.

  As shown in an enlarged view in FIG. 2, the ion curtain device 10 includes a first ion wind unit 30 and a second ion wind unit 32. The first ion wind unit 30 can discharge the first ion curtain 34 whose width direction is substantially vertical to advance in the first substantially horizontal direction (see arrow A in FIG. 3). In addition, the second ion wind unit 32 causes a second ion curtain 36 having a width direction in a substantially vertical direction to be in a second substantially horizontal direction B (see arrow B in FIG. 3) having an angle with the first substantially horizontal direction A. ) Can be released as it progresses. Here, the first substantially horizontal direction A and the second substantially horizontal direction B are set at right angles to each other, the first ion curtain 34 is advanced to the first inner wall 20 side, and the second ion curtain 36 is moved to the second inner wall 22 side. Proceed to. As a result, the first ion curtain 34, the second ion curtain 36, the first inner wall 20, and the second inner wall 22 constitute four side surfaces of a predetermined space having a cubic shape.

  Both the first ion wind unit 30 and the second ion wind unit 32 are fixed to the holding frame 38. Specifically, the holding frame 38 includes an L-shaped inner wall 38A and an L-shaped outer wall 38B parallel to the inner wall 38A in a plan view, and the L-shaped inner wall 38A and the L-shaped outer wall 38B. The first and second ion wind units 30 and 32 are installed so as to be sandwiched between them.

  Further, ion emission ports 40 are formed at both ends of the holding frame 38 (both ends of the L-shape), and extend vertically in the middle (bent region) of the L-shaped outer wall 38B. An air inlet 42 is formed. A mesh-like safety fence is installed at the ion emission port 40 and the intake port 42 so that a hand or the like is not accidentally inserted. Proximity sensors 44 are disposed inside the ion emission port 40 and the air intake port 42, respectively, and detect the entry of foreign matter from the ion emission port 40 and the air intake port 42 to detect the first and second ion wind units 30. , 32 is stopped. Note that the safety fence of the air inlet 42 formed at the L-shaped bending point is curved so as to protrude outward, and a long distance from the first and second ion wind units 30 and 32 inside is ensured. Thus, even if a foreign object is inserted from the safety fence, it is considered that the first and second ion wind units 30 and 32 are not easily reached. This curved safety fence also contributes to the improvement of design.

  The first ion wind unit 30 and the second ion wind unit 32 are in a state in which the air intake openings 30A and 32A are close to each other, that is, in a state in which the air intake openings 30A and 32A are located on the intermediate side of the L-shape. It is held by the holding frame 38. As a result, the air flow path R that branches the air introduced from the air inlet 42 into the holding frame 38 and guides it to the air intake openings 30A, 32A of the first and second ion wind units 30, 32. Will be formed.

  Next, the structure of the first and second ion wind units 30 and 32 will be described. In addition, since both structure is the same, description of the 2nd ion wind unit 32 is abbreviate | omitted by demonstrating 1st ion wind unit 30 concretely here.

  As shown in FIG. 3, the first ion wind unit 30 includes three unit pieces 50, 52, and 54, each of which can discharge ion wind independently. These unit pieces 50, 52, and 54 are detachable from the holding frame 38, and can be periodically removed and cleaned.

  The unit piece 50 includes a needle electrode 56, a plate electrode 57, and an electrode case 58. The electrode case 58 is formed in a cylindrical shape and accommodates the needle electrode 56 and the plate electrode 57 therein, and both end surfaces in the horizontal direction are open. One opening on both end faces is an air intake opening 30A, and the other opening is an ejection opening 30B of the ion curtain. The electrode case 58 is made of a synthetic resin having a high insulation characteristic so that the needle electrode 56 and the plate electrode 57 are insulated from each other.

  Needle electrode 56 is located on the center in the width direction of electrode case 58 and closer to air intake opening 30 </ b> A. Note that. A holding bar 59 is provided on the inner wall of the electrode case 58, and the needle electrode 56 is held at the tip of the holding bar 59 (see FIG. 2). Here, the needle electrode 56 is formed of a rod-shaped stainless steel plate, and needle-like protrusions 56A are formed at regular intervals in the longitudinal direction. The needle-like protrusion 56A has a substantially triangular shape with a sharp tip, and electrons are emitted from the tip. The first ion curtain 34 is formed by these electrons.

  The plate electrodes 57 that form a set of two plates are arranged in parallel in an opposed state on the inner wall of the electrode case 58 closer to the ejection port 30B side. Therefore, the needle electrode 56 is positioned between the pair of plate electrodes 57 and upstream of the ion curtain. The plate electrode 57 is constituted by a flat plate made of stainless steel. Although not particularly illustrated, the left and right edges (horizontal orientation edges) of the stainless steel plate are folded back to the inner wall side of the electrode case 58 so that the edges of the steel plate are not directly exposed.

  As shown in FIG. 3, a power supply device 60 is installed further below these unit pieces 50, 52, 54. The power supply device 60 supplies a high voltage to all three unit pieces 50, 52, and 54. Although not specifically shown, the power supply device 60 includes a high voltage generation circuit including a high voltage transformer for generating a high voltage, a switching circuit that supplies an input voltage, a rectifier circuit that converts an AC voltage into a DC voltage, and a high voltage generation circuit. And a control circuit for controlling the switching circuit so that the output voltage is constant. As a result, a negative high voltage is applied to the needle electrode 56 and a positive high voltage is applied to the plate electrode 57.

  When a high voltage is applied between the needle electrode 56 and the plate electrode 57, dielectric breakdown occurs in the space between them, and corona discharge occurs from the tip of the needle electrode 56. Accordingly, a large amount of electrons are emitted from the tip of the needle-like protrusion 56A. When the moving speed of the electrons is high, the electrons are discharged from the ejection port 30B without being collected by the plate electrode 57, and the first ion curtain 34 is formed by the electrons.

  In the first ion curtain 34, since the ion wind flows in the form of a film, these electrons give electrons to dust, bacteria, odor components (odor particles), smoke particles, etc. Neutralize. As a result, the Brownian motion of smoke particles and the like is suppressed, and is guided along the flow of the first ion curtain 34 in a certain direction without being disturbed. As a result, smoke particles or the like cannot pass through the first ion curtain 34, and thus function as a blocking wall that substantially isolates the inner and outer spaces.

  A certain non-curtain region P is formed on the lower side (floor 28 side) of the first ion curtain 34 in the width direction (vertical direction). As described above, this is because the power supply device 60 is disposed below the unit pieces 50, 52, 54. However, smoke particles and the like basically have a characteristic of moving upward. Therefore, even if the non-curtain region P exists on the floor 28 side, there is no problem as a shielding function. Further, when the air in the predetermined space is forcibly exhausted, fresh air can be positively introduced from the non-curtain region P, and an ascending air current can also be formed in the predetermined space.

  On the upper side in the width direction of the first ion curtain 34 (the ceiling 24 side), the first guide plate 12 is installed along the first ion curtain 34. The first guide plate 12 is fixed to the ceiling 24, and the lower end side of the first guide plate 12 is disposed so as to overlap the upper end of the first ion curtain 34. That is, the upper end of the ion emission port 40 in the ion curtain device 10 and the first guide plate 12 overlap in the vertical direction. Further, the first ion curtain 34 is located inside the predetermined space with respect to the first guide plate 12. As a result, the first guide plate 12 prevents dust, bacteria, odor components (odorous particles), smoke particles, etc. in the predetermined space from passing over the upper end of the first ion curtain 34 and flowing out to the outside. it can. Further, the inner and outer peripheral surfaces of the first guide plate 12 can be used as an advertising space, and it is possible to display advertising / advertisement information such as events, campaigns, and products.

  Next, the operation of the ion shielding space constituting apparatus 1 will be described. As shown in FIG. 4, the first or second ion curtains 34 and 36 discharged from the ion curtain device 10 travel straight toward the first inner wall 20 and the second inner wall 22, respectively. Reflector plates 16 are installed in the first inner wall 20 and the second inner wall 22 at locations where the first and second ion curtains 34 and 36 are located, that is, at two corners of a predetermined space to be shielded. ing. The reflecting surface of the reflecting plate 16 extends in the vertical direction to the extent corresponding to the width of the first and second ion curtain devices 10 and is inclined so as to face the center side of the predetermined space. The Therefore, when the first or second ion curtain 34, 36 advances straight and comes into contact with the reflecting plate 16, it is bent (reflected) toward the inside of the predetermined space. As a result, the dust C or the like floating in the predetermined space is guided along the first and second ion curtains 34 and 36 and returned to the predetermined space again, and the shielding state is maintained. Is possible.

  In the ion shielding space constituting apparatus 1, the ion curtain device 10 is disposed at one corner of a predetermined space, and the first and second ion curtains 34 and 36 discharged from the one corner are provided in advance. The first and second inner walls 20 and 22 are capable of easily forming a shielded space. Moreover, compared with the case where an ion wind unit is built in the ceiling, the labor of enforcement is reduced and the introduction cost is significantly reduced. Further, since the first ion wind unit 30 and the second ion wind unit 32 are integrally held in the ion curtain device 10, it is easy to carry and implement while forming an external appearance with a sense of unity. I can do it. Therefore, it is particularly suitable when a smoking booth is prepared for a limited time or when a clean environment is temporarily formed.

  Moreover, in this ion curtain apparatus 10, the 1st and 2nd ion wind units 30 and 32 share the inlet 40 formed in the holding | maintenance frame 38, and are drawing in external air efficiently. As a result, it is possible to discharge the ion curtain in two directions while maintaining a state of excellent design.

  In this ion curtain device 10, the ion curtain device 10 can be configured in a simple column shape by efficiently arranging the power supply unit 60 in the non-curtain region P (see FIG. 3) where the ion curtain is unnecessary. It has become. Moreover, since the heavy power supply unit 60 is arrange | positioned below compared with the other unit pieces 50 grade | etc., Stability of the ion curtain apparatus 10 can be improved. Further, the rising dust and smoke particles are surely confined in the space by the physical first and second guide plates 12 and 14, so that the dust and the like are leaked to the outside through the ceiling 24 side. It is preventing. The guide plates 12 and 14 can also be used as advertising means by displaying advertisement information such as tobacco companies and cigarettes, for example. Further, since the first and second ion curtains 34 and 36 are reliably folded back into the space by the reflection plate 16, it is possible to prevent leakage of dust and the like in the vicinity of the reflection plate 16.

  Next, an ion shielding space constituting apparatus 101 according to the second embodiment will be described with reference to FIG. Regarding the ion shielding space constituting apparatus 101, the same or similar members or the like as those of the ion shielding space constituting apparatus 1 of the first embodiment will be omitted from description by matching the last two digits in the drawings.

  The ion shielding space constituting apparatus 101 is capable of constructing a shielded predetermined space not only in a facility corner but also in an arbitrary space. Specifically, the ion shielding space constituting apparatus 101 includes a third guide plate 160 and a fourth guide plate 162 in addition to the first guide plate 112 and the second guide plate 114, and further includes these first to fourth guide plates. A pseudo ceiling 164 covering the space surrounded by the guide plates 112, 114, 160, 162 is provided. In addition, pillars 166 are installed at three corners of the first to fourth guide plates 112, 114, 160, and 162 except for the corner where the ion curtain device 110 is disposed. And the pseudo ceiling 164 etc. are held upward by the ion curtain device 110.

  Further, the third guide plate 160 and the fourth guide plate 162 are each provided with a cloth-like curtain 168 that is coated with a photocatalyst and can be wound up in a roll shape. I try to shield it. The first ion curtain 134 and the second ion curtain 136 each collide with the cloth curtain 168. As a result, a space in which the four surrounding surfaces are shielded by the two cloth curtains 168 and the first and second ion curtains 134 and 136 can be secured. Further, a forced exhaust device 170 is installed on the pseudo ceiling 166, and the air inside the ion shielding space constituting device 101 can be forcibly exhausted to the outside through the exhaust pipe 172.

  According to the ion shielding space constituting apparatus 101, it is possible to install a smoking space or the like separated from the outside at any place. Specifically, since the ion curtain by the ion curtain device 10 and physical shielding means such as the pseudo ceiling 164 and the cloth curtain 168 are efficiently combined, a special facility such as a gymnasium or an exhibition hall where the ceiling is too high. In addition, even in an outdoor space where no ceiling exists, a shielded space can be configured. In addition, since the two surfaces constituted by the first ion curtain 134 and the second ion curtain 136 can freely enter and exit, it is possible to secure a highly convenient space such as an open space.

  Next, an ion shielding space constituting apparatus 201 according to the third embodiment will be described with reference to FIG.

Accordingly, the first ion curtain 234 and the second ion curtain 236 released from the first ion curtain device 210, and the third ion curtain 282 and the fourth ion curtain device 284 released from the second ion curtain device 280 are used as outer peripheries. The shielding wall is configured. In the remaining two corners of the predetermined space, the reflection plate 216 is arranged so as to serve also as a support. The first ion curtain 234 and the fourth ion curtain 284 are in contact with one reflector 216 and bent toward the shielding space. Similarly, the second ion curtain 236 and the third ion curtain 282 also come into contact with the other reflector 216 and bend toward the shielding space.

  According to the ion shielding space constituting apparatus 201, a space in which the entire periphery is shielded by the ion curtain is constructed, so that the entrance and exit from all sides is free, and an extremely open shielding space can be formed. Yes. Further, by arranging the two ion curtain devices 210 and 280 diagonally, space saving is measured, and any space can be easily introduced.
