Description

  The present invention relates to an ozone supply device that not only exterminates insects such as cockroaches, termites, and ticks lurking in the shade, but can effectively deodorize malodors that fill the room.

  Ozone is a pale blue gas with a unique odor and strong oxidizing power, and is used for purposes such as disinfection, bleaching and oxidation. It is known from Japanese Utility Model Laid-Open No. 61-74375 to use an ozone generator in a method for controlling cockroaches. In Japanese Utility Model Laid-Open No. 61-74375, an ozone generator is attached to the ceiling or kitchen room of a kitchen, and a small slow fan is combined with the ozone generator. This ozone generator is installed in a container having an air inlet and an air outlet, and air containing ozone is forcibly blown into the room by a small slow fan.

Devices for controlling pests with ozone are also disclosed in Japanese Utility Model Laid-Open No. 63-58575, Japanese Patent Laid-Open Nos. 2-303440 and 5-170610. In Japanese Utility Model Laid-Open No. 63-58575, a fan and an ozone lamp are installed in the container in the middle of a passage between an air inlet and an ozone outlet, and the lighting time of the ozone lamp is controlled by a timer. Japanese Patent Laid-Open No. 5-170610 includes an ozone generating means and an ozonolysis means. In this removal apparatus, one opening, an inorganic catalyst layer, an ozone generator, an acid-carrying absorbent layer, a reversible fan, and the other The openings are arranged in order. This extermination device can exterminate pests in a short time with a simple operation, and ozone remaining in the atmosphere after ozone treatment can be decomposed into oxygen in a shorter time by using an inorganic catalyst layer.

  The above-mentioned pest control apparatus blows out generated ozone by a fan and increases or decreases the number of rotations of the fan to change the amount of air blown. Ozone is present in a small amount of 0.02 to 0.04 ppm in the air. Ozone is only about 0.05 ppm in the air, so it has a unique odor and is very toxic. It will invade the respiratory tract when the concentration is about 0.3 ppm, and it may be harmful if inhaled for a long time. is there. For this reason, the fan of this pest control apparatus usually has a considerable air volume and is set so that the generated ozone does not stay in the vicinity of the apparatus.

  When the fan air blow rate of this pest control device is considerably high, even if a large amount of ozone is generated, the amount of air mixed in decreases, and the ozone diffuses at a high speed, resulting in a low concentration of ozone. Although low-concentration ozone is effective for destroying cockroaches and mites, it can destroy harmful animals such as rats and deodorize strong odors in garbage disposal sites, snacks, restaurants, warehouses, etc. I can't.

  On the other hand, if high-concentration ozone is discharged by lowering the fan air flow rate in order to enhance the deodorizing effect, high-concentration and low-speed ozone will stay in the vicinity of the device, and the odor of ozone will be felt, resulting in a toxic effect. It is dangerous to get higher. Even if the low-speed ozone comes into contact with bad odor, it is separated at the boundary and does not mix with the bad odor, and deodorization by oxidation cannot be achieved.

  The present invention has been proposed in order to improve the above-described problems associated with conventional ozone generators, and provides an ozone supply device that can reliably deodorize bad odors filled in a room by oxidation with a high air flow rate. The purpose is that. Another object of the present invention is to provide an ozone supply device that can be safely installed at an arbitrary place for pest control or the like.

  The ozone supply apparatus according to the present invention is an integrated type that can be installed at any place by hanging or standing. The ozone supply device of the present invention includes an ultraviolet ozone lamp that generates a large amount of ozone, an inner cylinder that houses the ozone lamp, an outer cylinder that is arranged substantially coaxially with the inner cylinder, It consists of a ventilation fan installed at the rear of the cylinder, and the rear end surface of the inner cylinder is closed by a support member, and a small hole through which air can flow is provided in the support member. Thereby, in the ozone supply device of the present invention, the air flow inside the inner cylinder is made slower than the air flow between the outer cylinder and the inner cylinder.

  In the ozone supply device of the present invention, it is preferable to attach an ozone lamp to a support member that closes the rear end surface of the ozone supply device inner cylinder. Preferably, a perforated plate capable of air circulation is attached to the front end face of the outer cylinder, and a baffle plate is installed close to the rear of the perforated plate so that the light of the ozone lamp does not leak out of the apparatus. Further, the inner cylinder is shorter than the outer cylinder, and its front peripheral end does not reach the perforated plate at the front end of the outer cylinder, so that the air flow inside the inner cylinder before the ozone supply device exits the outer cylinder And an air flow between the inner cylinder and the inner cylinder.

  In the ozone supply device 1 (FIG. 1), the inner cylinders 3 arranged inside the outer cylinder 5 are usually shorter than the outer cylinders 5 and are slightly out of the coaxial position even if they are substantially coaxial. May be. The coaxial arrangement of the inner cylinder 3 is achieved by bolting the receiving plate portions 40 and 42 (FIG. 3) welded to the upper end of the inner cylinder 3 and the pair of support pieces 24 and 26 welded to the inner peripheral wall of the outer cylinder 5. Even if it is achieved, it may be set with an appropriate frame (not shown) such as a donut shape fitted into the outer cylinder 5.

  In the embodiment of the present invention, two ultraviolet ozone lamps 2 are accommodated in the inner cylinder 3, and one or three or more ozone lamps may be provided. When the two ozone lamps 2 are accommodated in the inner cylinder 3, high-concentration ozone can be obtained at a relatively low ventilation speed. The air in contact with the ozone lamp 2 flows into the inner cylindrical body 3 through a small hole provided in the support member 46 that closes the inner cylindrical body 3, so that the small hole is relatively slow. Even if it is the cyclic | annular space | gap (FIG. 4), the through-hole of another shape may be sufficient. By adjusting the size of the annular gap, which is a small hole, the ventilation speed in the inner cylinder 3 can be controlled appropriately. Instead of this annular gap, it is also possible to adjust the ventilation speed into the inner cylindrical body 3 by a remotely operable opening / closing member or the like.

  A perforated plate 14 is welded to the front end of the outer cylindrical body 5 and a circular baffle plate 20 having the same size as the perforated plate is installed in the vicinity. The circular baffle plate 20 is safe because it moderately suppresses the ventilation speed in the apparatus 1, prevents the light from the ozone lamp 2 from leaking out of the apparatus during operation of the apparatus 1, and makes it invisible from the outside of the apparatus. . The ventilation speed in the apparatus 1 can be controlled by increasing or decreasing the rotation speed of a ventilation fan such as the sirocco fan 8.

  Although not shown, the ozone supply device 1 has a ventilation fan, an input switch for the ozone lamp 2 and a power cord with a plug attached to the rear cylinder 7 and has a built-in timer so that it can be operated indoors for a certain period of time at night. Also good. In a sealed room, the ventilation fan is always operated to diffuse ozone, but it is preferable to control the lighting time of the ozone lamp 2 with a timer. Further, the outer cylinder 5 can be equipped with an ozone decomposition mechanism together with an ozone generation mechanism.

  An ozone supply device according to the present invention has an inner cylinder and an outer cylinder in which an ozone lamp is installed, and air that circulates inside the inner cylinder circulates between the outer cylinder and the inner cylinder. Since it is slower than this, relatively high concentration ozone can be discharged at high speed. The ozone supply device of the present invention does not require a low fan blowing rate when high concentration ozone is required to enhance the deodorizing action, and can be operated at a relatively high blowing rate. It is. Therefore, unlike the conventional case, high-concentration discharged ozone stays in the vicinity of the apparatus and does not feel a peculiar odor and is safe, and ozone is not diluted more than necessary and fills the room. Odor can be reliably removed by oxidation.

  The ozone supply device according to the present invention can be easily installed indoors or under the floor, is effective for destroying cockroaches and mites, and is used to expel harmful animals such as rats and waste disposal with relatively high concentrations of ozone. Can be used to deodorize strong odors in places, snacks, restaurants, warehouses, etc. In the ozone supply apparatus of the present invention, ozone and a strong odor are not separated at the boundary when ozone at a predetermined air velocity comes into contact with the odor source, and the ozone is effectively mixed with the odor and consumed by oxidation. An odor can be reliably achieved.

  Next, the present invention will be described based on examples, but the present invention is not limited to the examples. FIG. 1 shows an ozone supply device 1 according to the present invention, which is a substantially cylindrical integrated type. The ozone supply device 1 includes an inner cylinder 3 in which an ultraviolet ozone lamp 2 is housed, and an outer cylinder 5 that is arranged substantially coaxially with the inner cylinder. A rear cylinder 7 having the same diameter is connected to the outer cylinder 5, and a ventilation fan, for example, a sirocco fan 8 is installed behind the rear cylinder.

  The outer cylinder 5 is, for example, a cylindrical shape having a diameter of 145 mm and a length of 268 mm, and both ends are formed in a flange shape. A donut-shaped circular plate 12 (FIG. 2) is closely bolted to the front flange portion 10, and a perforated plate 14 as a punching metal is welded to the back side of the circular plate. A part of the through hole 15 is shown in the porous plate 14 in FIG. Most of the porous plate 14 is exposed to the outside through the center hole 16 of the circular plate 12. By placing a circular baffle plate 20 in proximity to the back of the perforated plate 14 via a plurality of cylindrical separators 18, the perforated plate 14 and the baffle plate 20 have a predetermined gap. The diameter of the baffle plate 20 is slightly larger than that of the central hole 16 of the circular plate 12.

  In the outer cylinder 5, an L-shaped bar 21 is welded to the upper end of the outer periphery, and the L-shaped bar is located at the center of gravity of the device 1 in the axial direction. The L-shaped bar 21 is used as a handle metal fitting or a hanging metal fitting of the device 1. Further, a U-shaped bar 22 bent in a trapezoidal shape is welded to the front below the outer periphery of the outer cylindrical body 5, and a U-shaped bar (not shown) is also attached to the lower end of the outer periphery of the rear cylindrical body 7 corresponding to the U-shaped bar 22. ) Is preferably welded. The U-shaped bar 22 is used as a support member when the apparatus 1 is placed horizontally, and the U-shaped bar prevents the apparatus 1 from rotating on the floor. Further, a pair of rectangular flat support pieces 24 and 26 are welded to the inner peripheral wall of the outer cylindrical body 5, and screw holes (not shown) are provided in both support pieces. The distance between the support pieces 24 and 26 is substantially equal to the length of the inner cylinder 3, and the inner cylinder 3 is securely supported horizontally by fixing the front and rear of the inner cylinder 3.

  The rear cylinder 7 is concentrically connected by bolting to the rear flange part 30 of the outer cylinder 5 at the front flange part 28. The rear cylinder 7 has, for example, the same diameter as the outer cylinder 5 and a length of 200 mm, and both ends are formed in a flange shape like the outer cylinder 5. The rear cylinder 7 has a sirocco fan 8 mounted on a separator plate 32 installed at the rear thereof, and blows air toward the inner cylinder 3 and the outer cylinder 5 by the fan. Although not shown, the rear cylinder 7 houses a motor, a transformer, and the like for the sirocco fan 8, and a circular perforated plate or the like is bolted to the rear flange portion 33. The sirocco fan 8 is a one-stage centrifugal ventilation fan, generally having 60 to 90 short forward blades, suitable for low wind pressures of 15 to 200 mmAq with an efficiency of 55 to 65%, less sound, and a change in air flow rate. However, there is relatively little change in wind pressure.

  The inner cylinder 3 has, for example, a cylindrical shape with a diameter of 60 mm and a length of 206 mm, and a rear end portion is formed into a rectangular shape by forming a flange portion 34 (FIG. 3). Through holes 36 are respectively provided at the four corners of the rectangular flange portion 34. In order to arrange the inner cylinder 3 coaxially with the outer cylinder 5, the strip 38 is welded along the axial direction to the upper end of the outer wall, and the front and rear end portions of the strip are bent at right angles. Portions 40 and 42 (FIG. 3) are formed, and through holes 44 (FIG. 3) are provided in both attachment portions.

  Two elongated U-shaped ultraviolet ozone lamps 2 are accommodated in parallel in the inner cylindrical body 3 via a T-shaped flat support member 46 (FIG. 4). The support member 46 includes an orthogonal portion 48 having a size corresponding to the rectangular flange portion 34 of the inner cylinder 3 and a parallel portion 50 welded perpendicularly to the center in the width direction of the orthogonal portion. The orthogonal portion 48 is formed with a through hole 51 corresponding to each through hole 36 of the rectangular flange portion 34, and a double circular hole 56 into which the terminal portions 54 (FIG. 1) of both ozone lamps 2 are fitted is adjacent. To form. The double circular hole 56 is substantially line symmetric with respect to the parallel part 50 and has an inner diameter slightly larger than the outer diameter of the lamp terminal part 54, so that the annular gap of the double circular hole 56 is a small hole for air flow. It is possible to ventilate the inner cylinder 3 through this annular gap. On the other hand, the parallel portion 50 is an elongated rectangular plate having a height and a length substantially equal to the inner diameter and length of the inner cylinder 3, and through holes 58 and 58 for the fastening fittings 52 are provided behind the parallel portion 50. The parallel part 50 may be provided with a through hole 60 at the front lower side, and a front receiving metal fitting (not shown) of the ozone lamp 2 is attached to the through hole.

  To assemble the ozone supply device 1, the ozone lamps 2 and 2 are arranged on both sides of the parallel part 50 of the support member 46, and the lamp terminal part 54 is fitted into the double circular hole 56 of the orthogonal part 48. The rear ends of the lamps 2 and 2 are sandwiched by the fastening metal fittings 52 (FIG. 1) whose center is recessed, and bolts 62 are inserted into the through holes and the through holes 58 of both metal fittings and fixed with nuts. Next, the ozone lamps 2 and 2 are accommodated in the inner cylinder 3 together with the support member 46, and each through hole 51 of the support member 46 is matched with each through hole 36 of the inner cylinder 3 and bolted. The inner cylinder 3 is put into the outer cylinder 5 and the inner cylinder is slightly rotated so that the receiving plate portions 40 and 42 are aligned with the support pieces 24 and 26, and both are fixed with tapping screws 64 and 66. After the terminal portions 54 and 54 of the ozone lamp 2 are inserted into a socket (not shown) of an electric circuit, the rear cylinder 7 is bolted to the outer cylinder 5. Usually, the input switch of the ozone lamp 2 is attached separately from that of the sirocco fan 8.

  The ozone supply device 1 can be carried by hand as it is, and can be hung to an appropriate place by a chain or the like via an L-shaped bar 21, or placed on the floor and kept stationary by a U-shaped bar 22. It is also possible to place the cylinder 5 vertically with the cylinder 5 facing upward. After the ozone supply device 1 is arranged at an appropriate place, a plug (not shown) of a power cord extending from the rear cylinder 7 may be inserted into a household power supply jack. When the switch is turned on, the sirocco fan 8 rotates and blows air from the rear cylinder 7 to the outer cylinder 5. Most of the air flows between the outer cylinder 5 and the inner cylinder 3. A part of this air flow flows into the inner cylinder 3 through the annular gap of the double circular hole 56 of the support member 46 that closes the inner cylinder 3, and together with the ozone generated by the ozone lamps 2, 2, the inner cylinder After leaving the body 3, it is mixed with air flowing between the outer cylinder body and the inner cylinder body 3 at the front part of the outer cylinder body 5, and this mixed air passes through the baffle plate 20 from the porous plate 14 to the outside of the apparatus. Spill to

  In the ozone supply device 1, the air flowing between the outer cylinder 5 and the inner cylinder 3 has a relatively low speed because of its low resistance. On the other hand, the air flowing through the inner cylinder 3 is relatively slow because the resistance in the support member 46 is large, and when the low-speed air comes into contact with the ozone lamps 2 and 2 that generate a large amount of ozone, the air has a relatively high concentration. Of ozone can be sent out. The high-concentration ozone that is low in speed is mixed with relatively high-speed air in the outer cylindrical body 5, so that the relatively high-concentration ozone can be discharged at high speed.

  The ozone supply device 1 is disposed above the room and discharges a relatively high concentration of ozone at a high speed, so that the ozone comes into contact with a bad odor source in the room and adheres to the bad odor and the wall or carpet filling the room. Deodorize surely by oxidation. The ozone supply device 1 can be used at night or the like to reliably deodorize strong odors in garbage disposal sites, snacks, restaurants, warehouses, and the like. If the ozone supply device 1 is placed indoors or under the floor, it can destroy pests such as cockroaches and mites, and can also destroy harmful animals such as mice at a relatively high concentration.

  When the ozone supply device 1 continues to be used in a sealed room, the ozone odor can be felt when the ozone concentration reaches about 0.06 ppm in the room. The sirocco fan 8 continues to rotate and continues to diffuse ozone only. On the other hand, if the concentration of ozone decreases to about 0.03 ppm due to diffusion and oxidation, the ozone lamps 2 and 2 are turned on to restart the generation of ozone.
