Description

  The present invention relates to a phytoncide discharge fan that can dissipate phytoncide for deodorization, deterrence, and insect control, and a ventilator system that assists ventilation under the floor of a house or behind a ceiling, and also performs deodorization, deterrence, and insect prevention.

  Conventionally, much of ventilation such as under the floor and behind the ceiling is performed by a ventilation fan installed in the target area. However, the underfloor and the ceiling are shaded, and the daily temperature fluctuation is small, often resulting in a high humidity state due to insufficient ventilation. For this reason, mold | fungi generate | occur | produce under a floor, a ceiling back, etc., decaying fungi etc. propagate and pests, such as a white ant, a tick, and a centipede, inhabit, and it will become a sanitary and unpleasant environment. In addition, wood decays in a harsh environment, generating a unique odor.

  In order to prevent the occurrence of such mold, the decay of wood, the damage of white ants, etc., a ventilation device provided with an ozone generator has been proposed (Patent Document 1). This ventilator is equipped with an ozone generator, which electrically generates ozone at the part where outside air is introduced and fumigates it under the floor or ceiling. The ozone concentration can be set arbitrarily, and the strong oxidizing power of ozone prevents the decay of wood and damage such as white ants.

  An air conditioner that sprays medicine instead of ozone has also been proposed (Patent Document 2). That is, in this technique, the air conditioner is intermittently operated and ventilated, and at that time, a spraying device is provided in the ventilation path of the main casing of the air conditioner, and an insect repellent or the like is sprayed by the spraying device. Is. As a result, an insect repellent or the like is sprayed under the floor together with the blown air, and damage of harmful insects such as white ants inside the floor is prevented.

  Hereinafter, the ventilator system and the phytoncide discharge fan according to the first embodiment of the present invention will be described. Example 1 is a ventilator system in which a ventilation area is under the floor and a diffusion fan is used as a fan for discharging phytoncide. FIG. 1 is an overall view of a ventilator system in Embodiment 1 of the present invention, FIG. 2 is a plan view of a diffusion fan in Embodiment 1 of the present invention, and FIG. 3 is a side view of the diffusion fan in Embodiment 1 of the present invention. 4 is a front view of the diffusion fan in Example 1 of the present invention, FIG. 5 is an XX sectional view of the diffusion fan in FIG. 2, and FIG. 6 is a YY sectional view of the diffusion fan in FIG.

  In FIG. 1, reference numeral 1 denotes a ventilation area such as a floor or a ceiling, 1 a denotes a wall portion constituting the ventilation area 1 such as a foundation wall or a ceiling wall under the floor, and 2 denotes a ventilation area 1 for sucking outside air. Ventilation ports 3 are exhaust ports for discharging the air in the ventilation area 1.

  4 is an exhaust fan that is attached to the exhaust port 3 and exhausts air in the ventilation region 1 and sucks outside air from the ventilation port 2 by this negative pressure, 5 is installed in the ventilation region 1 and contains phytoncide liquid, It is a diffusion fan (the phytoncide discharge fan in Example 1 of the present invention) that diffuses vaporized phytoncide. Note that phytoncide is a secondary metabolic component of plants produced by photosynthesis by plants, and is a so-called life-active substance. Next, 6 is a phytoncide generator that is disposed at the upper part of the discharge side of the diffusion fan 5 and that contains phytoncide liquid extracted as plant essential oil. Details will be described later. The exhaust blower 4 and the diffusion blower 5 constitute the ventilator system of the first embodiment that performs deodorization, insect proofing, fouling prevention, fragrance addition and the like together with ventilation. It is preferable to drive the vehicle. In addition, since the phytoncide liquid has an antibacterial action, the structure using this antibacterial action is also possible.

  The exhaust blower 4 of the first embodiment employs a cross flow type blower. This type of blower can discharge a relatively large air volume. Further, a centrifugal blower is employed as the diffusion blower 5 and discharges air having a pressure higher than that of the cross flow type. Therefore, the flow discharged from the diffusion blower 5 has a high flow velocity, and the two flows are substantially the same in order to discharge the blower in parallel with the discharge direction of the blower 4 against the ventilation flow by the exhaust blower 4. The momentum is exchanged while flowing in the direction. For this reason, the discharge flow discharged from the diffusion blower 5 does not disturb the ventilation flow so much, the fluid particles diffuse between the two flows due to viscosity, and the phytoncide contained in the discharge flow is diffused to the surroundings. It will be. Thus, the discharge flow from the diffusion blower 5 and the flow of ventilation by the exhaust blower 4 cause various flows and mixing in the ventilation region 1, and then exhausted by the exhaust blower 4. In this diffusion and mixing process, the phytoncide emitted from the phytoncide generator 6 is diffused into the ventilation region 1 and its components are evenly distributed in the ventilation region 1.

  Next, the structure of the diffusion fan 5 will be described with reference to FIGS. 2 to 4, reference numeral 11 denotes a casing of the centrifugal diffusion fan 5, 11a denotes a spiral casing that recovers pressure in the casing 10, and 11b denotes a discharge casing that discharges a flow from the spiral casing 11a. Reference numeral 12 denotes a suction port for sucking air provided in the casing 11, and 13 denotes a suction vane provided to make the suction flow into a swirl flow. Since the multi-blade impeller 21 is provided in the diffusion fan 5 as will be described later, the air is smoothly sucked by the suction vane 13 to obtain a highly efficient flow.

  2 to 4 and 5, 14 is a diffusion diffuser attached to the discharge casing 11b. The phytoncide generator 6 is detachably fixed to the upper surface of the diffusion diffuser 14. 14a is a flat fan-shaped discharge port formed in the diffusion diffuser 14, and 14b is a guide vane. Reference numeral 15 denotes a mounting leg of the diffusion diffuser 14. It is provided in four places along the outer periphery of the spiral casing 11a so that the casing 11 can be supported stably.

  A mounting opening is provided on one end side of the diffusion diffuser 14 and mounted on the discharge opening at the tip of the discharge casing 11b, and a fan-shaped discharge opening 14a is provided on the other end side and opened. The structure of the diffusion diffuser 14 is such that the circular mounting port on the discharge casing 11b side is gently deformed to change to a flat fan-shaped discharge port 14a. The fan-shaped discharge port 14a is fan-shaped and has a shape in which the flow is easily peeled off, so that the flow is stabilized by the guide vane 14b. The phytoncide diffuses in a process in which the flow discharged from the fan-shaped discharge port 14a and the surrounding flow are mixed by exchanging momentum due to viscosity.

  Next, the internal structure of the diffusion fan 5 and the phytoncide generator 6 will be described with reference to FIGS. Reference numeral 21 denotes an impeller, and reference numeral 21 denotes a motor for driving the impeller 21. The impeller 21 is a multi-blade impeller to increase the air volume. With this configuration, the motor 22 can be accommodated inside the impeller 21, and the thickness of the diffusion blower 5 in the height direction can be reduced to make it compact. Since the underfloor basically has no room in the height direction, this configuration makes it a blower suitable for underfloor ventilation and diffusion.

  The phytoncide generator 6 is a rectangular parallelepiped container in which a phytoncide liquid extracted as plant essential oil is housed, as shown in FIGS. 2 to 6, and is attached to the upper surface of the diffusion diffuser 14, and has a fan-shaped discharge port 14a. The phytoncide vaporized at the downstream position diverges into the discharge flow. The shape is not limited to a rectangular parallelepiped. In FIG. 6, 30 is an inlet cap for replenishing the phytoncide liquid, 31 is a liquid leakage prevention plate (liquid leakage prevention body of the present invention) provided so that the phytoncide liquid does not drop, and 32 is a phytoncide generator. 6 is a diverging hole that is provided on the side surface of the discharge flow side and that allows vaporized phytoncides to diverge into the discharge flow. Reference numeral 33 denotes a fixing protrusion used when the phytoncide generator 6 is attached to a predetermined position on the upper surface of the diffusion diffuser 14, and reference numeral 34 denotes an accommodating part for accommodating the phytoncide liquid. The cap 30 may be provided with a sheet that allows ventilation in one direction.

  One or a plurality of diverging holes 32 are opened. The phytoncide liquid is vaporized until saturated in the phytoncide generator 6 at room temperature. At this time, a part of the phytoncide passes through the gap between the liquid leakage prevention plate 31 and the inner surface of the container and circulates in the vicinity of the diverging hole 32 and is diverged from the diverging hole 32 into the discharge flow. Along with this, the fintoncide concentration in the phytoncide generator 6 decreases, and this causes mass transfer and vaporization of the phytoncide, so that the phytoncide is continuously emitted. The liquid leakage prevention plate 31 is formed to have a height sufficient to prevent the phytoncide liquid from dropping from the diverging hole 32.

  By the way, phytoncide is a component that plants produce by photosynthesis for self-defense, is a volatile substance, and the main component is an organic compound of terpenes. This component is contained in plant essential oil extracted from plants such as trees by distillation or extraction. Therefore, when using phytoncide liquid, it is better to use plant essential oil as it is as phytoncide liquid. Distillation methods for extracting plant essential oils include distillation with hot water and distillation with steam. Extraction methods include extraction with fat adsorption, extraction with solvents, and extraction with liquefied gas. The extracted plant essential oil is often used.

  Now, phytoncides have (1) a refreshing effect on the human body similar to that obtained in a forest bath, (2) a deodorizing / deodorizing effect that suppresses air purification and odor, and (3) antiseptic, sterilizing, antifungal, It is known to have an insect repellent effect, and recently it has been used as a fragrance bathing agent, cosmetics, hair restorer, and mouth disinfectant. The reason why phytoncide has such effects as (1), (2) and (3) is that when phytoncide is released into the air, it will come into contact with malodorous molecules floating in the air, causing neutralization and deodorization reaction, resulting in an odorless stable substance. The reason for this is to change, or to neutralize ozone, NOx, formaldehyde, etc., and to give a refreshing effect by giving a scent like cypress, hiba or cedar, and to give a refreshing feeling. In addition, phytoncide is naturally occurring and harmless to the human body, but it does not keep it against white ants, mites, mosquitoes, and molds, such as hinokitiol and camphor, α-pinene, limonene, picipheric acid, This is because it contains an antibacterial, insecticidal and antiseptic component such as allyl isothiocyanate, which has the effect (3).

  Therefore, when the phytoncide liquid, that is, the plant essential oil containing it, is vaporized and diffused in the ventilation area 1, it is possible to eliminate the decay of wood and the damage of white ants, etc., and further to provide fouling, deodorization and aroma. Thus, unpleasant environments such as under the floor and behind the ceiling can be changed to a cleaned-up space. In order to obtain an antibacterial action, not only gaseous phytoncide but also phytoncide liquid can be used.

  By the way, in Embodiment 1 of the present invention, one or a plurality of diverging holes 32 are formed in the phytoncide generator 6, and the phytoncides are diverged and mixed in the flow. Therefore, instead of electrically spraying the chemical liquid as in the conventional sprayer, a means that makes use of the characteristics of phytoncide that vaporizes the phytoncide liquid at room temperature and continuously dissipates and diffuses it from the diverging hole 32 into the discharge flow is adopted. doing. Thus, the phytoncide can be effectively diffused without requiring a separate power source or device. Not only the discharge flow but also the suction flow can be mixed as in the second embodiment.

  Further, the phytoncide generator 6 and the diffusion diffuser 14 may store the phytoncide liquid for a long time or may drip and remain attached to the surface. Although the phytoncide is diluted tens of thousands of times in a vaporized state and there is no problem in durability, it is desirable that the plastic container and the diffuser diffuser 14 that are in direct contact with the phytoncide liquid for a long time have durability as much as possible. Therefore, after intensive study on the durability of various plastics against phytoncide liquid, polypropylene, polycarbonate, and maltoplane have good durability, and polyethylene and styrene foam have a slightly eluted contact surface, and ABS resin has a deformed shape. Got.

  Therefore, in Example 1, polypropylene was adopted from among phytoncide-resistant materials such as polypropylene, polycarbonate, malt plain, and the phytoncide generator 6 made of polypropylene and the diffusion diffuser 14 were produced. Thus, by selecting a material from the phytoncide-resistant material, the diffusion blower 5 can be continuously operated without deterioration of equipment over a long period of time. In the first embodiment, polypropylene is used as the material of the diffusion diffuser 14, but since it does not normally drop from the phytoncide generator 6, the diffusion diffuser 14 may be made of ABS resin or the like. Good.

  As described above, the diffusion blower 5 according to the first embodiment attaches the diffusion diffuser 14, installs the phytoncide generator 6 at a predetermined position on the upper surface of the diffusion diffuser 14, and diffuses it into the ventilation area 1 such as under the floor or behind the ceiling. Therefore, deodorizing, insect-proofing, anti-fungal and the like in the ventilation area 1 can be performed with a phytoncide that is harmless to the human body.

  Further, in the ventilator system of the first embodiment, the diffusion fan 5 for diffusion is provided in the basic ventilation flow by the exhaust fan 4, so that the phytoncide is discharged to the ventilation region 1 simply by attaching the phytoncide generator 6. By operating the exhaust blower 4 and the diffusion blower 5 in conjunction with each other, it is possible to perform ventilation in the ventilation area 1 as well as deodorization, insect proofing, and fouling in the area with a phytoncide that is harmless to the human body. . It is possible to stop the operation of the exhaust blower 4 and operate the diffusion blower 5 alone to dissipate the phytoncide. However, the exhaust blower 4 and the diffusion blower 5 are operated in conjunction with each other from the viewpoint of the diffusion efficiency. It is desirable to do.

  A ventilator system and a phytoncide discharge fan according to Embodiment 2 of the present invention will be described. Example 2 is a ventilator system using a stirring fan as a blower for phytoncide discharge. 7 is an overall view of a ventilator system according to the second embodiment of the present invention, FIG. 8 is a plan view of the stirring fan in the second embodiment of the present invention, and FIG. 9 is a front view of the stirring fan in the second embodiment of the present invention. 10 (a) is a front view of the phytoncide generator in Example 2 of the present invention, FIG. 10 (b) is a side view of the phytoncide generator in FIG. 10 (a), and FIG. 10 (c) is the phytoncide generator in FIG. It is ZZ sectional drawing. Since the same reference numerals as those in the first embodiment have the same contents in the second embodiment, the description thereof will be omitted from the first embodiment.

  In FIG. 7, 1 is a ventilation area, 1a is a wall portion, 2 is a ventilation opening, 3 is an exhaust opening, 4 is an exhaust fan, 7 is an agitating fan installed in the ventilation area 1 and stirring and discharging phytoncide (this book) It is a phytoncide discharge fan in Example 2 of the invention. The exhaust blower 4 and the stirring blower 7 constitute a ventilator system according to the second embodiment that performs deodorization, deterrence, insect repellent and the like as well as ventilation.

  8 and 9, the details of the stirring fan 7 will be described. 6 is a phytoncide generator, 11b is a discharge casing, 12 is a suction port, and 13 is a suction vane. Reference numeral 17 denotes four discharge ports of the multivolute, each of which is provided with discharge vanes for rectification, and discharges in four directions. The reason why the four discharge ports 17 are provided in this manner is to discharge the discharge flow at an even angle of 90 ° across the impeller, thereby at least one discharge flow in at least four directions is used for exhaust. It is because it collides with the flow of ventilation toward the blower 4 and can greatly disturb the flow. In the second embodiment, the multi-volute has four discharge ports, but the number of discharge ports 17 may be two, three, or four or more.

  Thus, since the flow formed by the exhaust fan 4 is agitated by the discharge flow of the agitating fan 7, the phytoncide can be dissipated without using a high-pressure fan such as the diffusion fan 5 of the first embodiment. The running cost can be made cheaper than using.

  Next, the phytoncide generator 6 of Example 2 will be described. The phytoncide generator 6 of Example 2 is provided in the suction port 12. As shown in FIGS. 10A, 10B and 10C, 6a is a holder for installing the phytoncide generator 6, 31 is a liquid leakage prevention plate, 32 is a diverging hole, and 33 is for fixing to the holder 6a. The fixing protrusion 34 is a storage portion that stores the phytoncide liquid. The configuration of the phytoncide generator 6 is the same as that of the first embodiment, and detailed description thereof is omitted here. Here, a cap (not shown) or a sheet that allows ventilation in one direction may be provided on a part of the surface of the phytoncide generator 6.

  One end of the phytoncide generator 6 is attached to the holder 6 a in a cantilevered and inclined state, and the other end projects from the suction port 12. On the other end side, a diverging hole 32 is provided, which opens toward the suction port 12 in the suction flow. As a result, vaporized phytoncide is mixed into the air sucked from the diverging hole 32, and after being pressurized by the impeller, discharged from the discharge port 17 in multiple directions. Since the phytoncide generator 6 is mounted in a cantilevered manner, the suction flow toward the suction port 12 is hardly disturbed by the phytoncide generator 6. In the second embodiment, the phytoncide generator 6 may be attached to the suction port 12 of the spiral casing instead of the multivolute.

  The material of the phytoncide generator 6 is selected from phytoncide-resistant materials such as polypropylene, polycarbonate, and malt plain as in the first embodiment. And it is suitable to shape | mold the discharge casing 11b with a polypropylene, a polycarbonate, a malt plane, or coat the surface so that a phytoncide liquid may dripped on the discharge casing 11b. The suction vane 13 may also be made of a phytoncide resistant material to prevent dripping.

  As described above, the agitating blower 7 of Example 2 agitates the flow to form various flows, and thus, in this complicated mixing process, the diverged phytoncide is diffused into the ventilation region 1 and its components are removed. It can be evenly distributed in the ventilation area 1.

  In the ventilator system of the second embodiment, the basic flow of ventilation by the exhaust fan 4 is agitated by the agitating fan 7 so that the phytoncide can be discharged to the ventilation region 1 simply by attaching the phytoncide generator 6. it can. The deodorizing, insect-proofing and anti-fungal action in the ventilation area 1 can be performed harmlessly to the human body, and can be effectively stirred and diffused. Although it is preferable to operate the exhaust fan 4 and the stirring fan 7 in conjunction with each other, the phytoncide can be discharged by operating only the stirring fan 7 alone.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a ventilator system that assists ventilation under the floor of a house, a ceiling, and the like and dissipates phytoncides to deodorize, prevent insects, and prevent fouling. Further, the present invention can be applied to a phytoncide discharge fan for diffusing phytoncide.
