Description

  The present invention relates to an electric shock insecticidal device that is installed in a building eaves, a backyard of a kitchen, or the like to attract flying insects and kill them by electric shock.

2. Description of the Related Art Conventionally, a substantially rectangular parallelepiped having a front opening is provided, a lattice-shaped protective member is provided on the substantially rectangular parallelepiped so as to substantially cover the front opening, and a light source (instrument lamp) composed of a straight tube lamp is disposed in the front and rear of the substantially rectangular parallelepiped. Insects that are spaced apart from each other and arranged between the front and rear light sources with a lightning grid connected to the opposite poles of the high voltage generating circuit, attracted into the substantially rectangular parallelepiped by the light emitted from the light source and invaded the lightning grid part There is known an electric shock insecticidal device in which insects are killed by electric shock grids (see, for example, Patent Document 1).
JP 2001-252000 A (paragraphs 0002-0640, 0012, FIG. 1, FIG. 10 to FIG. 14)

  In the electric shock insecticide described in Patent Document 1, light emitted from a light source composed of a straight tube lamp passes through a front opening of a substantially rectangular parallelepiped and reaches an irradiation area limited based on the size of the front opening. However, since the size of the light source viewed from the insects in this area is the size of the straight tube lamp itself, the size of the light source unit viewed from the insects in the electric shock insecticide described in Patent Document 1 is the vertical direction. The size is equivalent to the size of two straight tube lamps arranged apart from each other.

  When the light source portion viewed from the insect is large as described above, the effect of attracting the insect toward the light source portion (insect attracting effect) is improved. However, since two straight tube lamps are required, the cost is high.

  At the same time, each of the two front and rear straight tube lamps needs to be arranged with a predetermined insulation distance with respect to the electric shock grid between them, so that a substantially rectangular parallelepiped is arranged in order to secure the arrangement space. Longer in the direction. Therefore, the conventional electric shock insecticide is large.

  Furthermore, a light source composed of a straight tube lamp emits light from its entire circumference, but most of the light directed in the direction opposite to the front opening of the substantially rectangular parallelepiped is not used for irradiating the irradiation area and is wasted. Therefore, the insect attracting effect is low in this respect.

  An object of the present invention is to provide an electric shock insecticidal device suitable for miniaturization in the front-rear direction at a low cost, while the insecticidal effect toward the light source can be enhanced with a minimum insecticidal light source to improve insecticidal performance. There is.

  The invention according to claim 1 is a main body in which the upper surface, both side surfaces, and the rear surface are closed and the front surface is opened; and a lattice-shaped protective member disposed on the main body so as to cover the opened front surface of the main body. A reflecting member provided in the main body for reflecting incident light to the front side; emitting an irritating light when lit, and illuminating the reflecting member and the open front surface of the main body with the irritating light at the front side of the reflecting member; An insect light source disposed in the main body; an electric shock grid disposed in the main body and one of the front and rear of the insect light source; and a high voltage applied to the electric shock grid attached to the main body A voltage applying device; and a reflecting plate, an attracting light source, and an insect receiving tray disposed on the main body and positioned below the lightning grid.

  In the present invention, the protective member can be formed by assembling a plurality of bars vertically and horizontally, or can be formed of a wire mesh or the like. The protective member having a lattice shape refers to a configuration that allows passage of insects invited by the light source but does not allow passage of objects such as human fingers larger than the insects.

  In the present invention, incident light refers to light inserted from a light source. Further, in the present invention, the reflecting member can be suitably formed by a reflecting plate installed separately from the main body, and can also be formed by the back plate itself with the rear surface of the main body closed. The reflecting surface of the reflecting member may be a diffuse reflecting surface or a specular reflecting surface.

  When the reflecting surface is a diffuse reflecting surface, it is preferable in that the entire reflecting member shines brightly by the incident light on the reflecting surface, and the reflecting member base material is made of a highly reflective material such as stainless steel as the diffuse reflecting surface. If the base material is not a highly reflective material, use a light diffusion layer such as white laminated on the base surface of the base material by painting or the like. It is possible.

  Further, when the reflecting surface is a specular reflecting surface, it is preferable from the viewpoint of obtaining reflected light having a high intensity, and also preferable for light distribution control. Further, the mirror reflection surface can be provided by laminating a metal reflection layer on the surface of the base material by, for example, plating or vapor deposition the surface of the base material of the reflecting member.

  In the present invention, the insect light source refers to a light source that outputs ultraviolet light (insect light) including a wavelength of 352 nm, which is recognized to have an effect of attracting insects. As the ultraviolet light output type insect light source, a straight tube type, a circular line type, or a single neck type fluorescent lamp can be used, and a light bulb type fluorescent lamp with a built-in ballast can be preferably used. In the present invention, the number of attracting light sources may be one or more.

  The use of the bulb-type fluorescent lamp as an irritating light source means that the size as an irritating light source is smaller than that of a straight tube type, a circular line type or a single-ended type fluorescent lamp, and accordingly, the electric shock grid and the like are also downsized. In addition, since the installation space for the ballast is not required, it is preferable for promoting the miniaturization of the electric shock insecticide. Further, as described above, as the size of the insect light source is reduced, when the light emitted from the light source is controlled by the reflecting member, the control becomes easy. Furthermore, it is also preferable for ultraviolet irradiation aiming at a target irradiation area. In addition, since the light bulb type fluorescent lamp consumes less power than the straight tube type, the circular line type, or the single neck type fluorescent lamp, the light bulb type fluorescent lamp is attracted to the insect even in the case where it is lit continuously for a long time at night. The use as a light source is also preferable for promoting energy saving.

  In this invention, the lightning grid is not arranged in an annular shape so as to surround the insect light source, or is arranged on both the front and rear sides of the insect light source, but in front of the insect light source (that is, the insect light source and the protection). Between the lure light source (ie, between the lure light source and the reflective member). The lightning grid can be arranged substantially in parallel with the protective member, and when the attracting light source is a light bulb type fluorescent lamp, it can be arranged in an arc shape so as to substantially follow the half circumference of the lamp. It is possible to arrange in.

  In the present invention, examples of the voltage applying device include a high-voltage transformer, but are not limited thereto. At the same time, it is preferable that the voltage application device is provided in the main body so as to be positioned above the reflecting member, the electric shock grid, and the insect light source. In the present invention, the insect tray can be detachably attached to the main body, or can be formed by a bottom wall that closes the lower surface of the main body. In the latter case, it is preferable that at least a part of the bottom wall is formed to be openable and closable in order to enable cleaning of the bottom wall that also serves as an insect tray.

  In the invention of claim 1, the lure light source emits lure light around it, and the lure light directly directed to the front side from the lure light source passes through the protective member disposed on the open front surface of the main body and is outside the main body. Lighted. On the other hand, since the insect light directed toward the rear side from the insect light source is incident on the reflecting member, it is reflected to the front side by this reflecting member and is projected outside the main body through the protective member. In this way, it is possible to suppress wasting of the attracting light directed toward the rear side of the attracting light source by the reflecting member and to project the light toward the front of the main body, so that the attracting effect is enhanced. In addition, the lure light source is reflected on the reflecting surface of the reflecting member on the rear side, and this reflecting member becomes a pseudo secondary photogen. Therefore, the size of the light source seen from the insects outside the main body is apparently increased, so that the insect attracting effect is enhanced.

  The increase in the insect attracting effect due to the increase in the amount of light and the apparent size of the light source can be enhanced as the number of the attracting light sources increases. However, since the number of attracting light sources can be realized, the number of attracting light sources can be minimized. The effect of attracting insects toward the light source is enhanced, and accordingly, the performance of killing insects that invade the electric grid by electric shock can be improved. In addition, the number of attracting light sources used can be minimized without requiring a large number of attracting light sources in order to ensure a large size of the attracting light source viewed from the insects outside the main body. Thereby, cost can be reduced.

  At the same time, since the lightning grid is arranged only in front of or behind the lure light source, the space in the front-rear direction required for placing the lightning grid and the lure light source is provided with the lure light source on both sides before and after the lightning grid. Compared to the configuration and the case where the electric grid is arranged in an annular shape surrounding the insect light source, the half is sufficient. Therefore, it is suitable for shortening the length in the front-rear direction of the main body having the built-in lightning grid and the lure light source, thereby further reducing the cost.

  According to a second aspect of the present invention, in the first aspect of the invention, the reflecting member is disposed behind the lure light source and the electric grid, and the reflecting member reflects incident light obliquely downward to the main body. It has a light distribution control unit that allows the open front surface to pass therethrough.

  In the invention of claim 2, a part of the insect light incident on the reflecting member is reflected obliquely downward by the light distribution control unit of the reflecting member and passes through the open front surface of the main body, thereby The light distribution to the irradiation area based on the size of the front opening can be controlled to be small in the upward direction and to be secured in the obliquely downward direction. Thereby, it is possible to irradiate insect light by focusing on a specific irradiation area to improve the insect attracting effect, and to attract insects outside the specific irradiation area so as not to kill them.

  The invention of claim 3 is the invention of claim 1 or 2, further comprising a protective layer made of a light-transmitting material in which the reflecting member is laminated on the reflecting surface and having a higher slipperiness than the reflecting surface. It is characterized by being.

  In this invention, the protective layer can be formed of, for example, a coating layer made of a transparent ethylene tetrafluoride resin, or may be a layer made of a transparent titanium oxide that exhibits a photocatalytic action.

  In this invention of Claim 3, it can suppress that the reflective surface of a reflection member fogs with the protective layer of a reflection member. At the same time, since the protective layer has high slipperiness, the insect carcasses that have scattered by the electric shock insects and reached the reflecting member are difficult to adhere to the surface of the reflecting member, and it is easy to remove the adhering carcass. It is.

  According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the electric shock grid is arranged in a substantially semicircular arc shape in plan view so as to surround the insect light source in the circumferential direction. It is characterized by being.

  In the invention of claim 4, since the electric shock grid is disposed so that the distance of each part of the electric shock grid with respect to the insect light source is substantially equal, the insect that is attracted to the body and flies around the light source is Increases the chance of being killed by an electric shock.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, an eaves-like light-shielding convex portion is provided, and the light-shielding convex portion is provided on the upper side of the opened front surface of the main body. It is characterized by protruding forward.

  In the invention of claim 5, the eaves-like light-shielding convex portion can block the enticing light that passes obliquely upward through the open front surface of the main body. It is possible to prevent the surface coating from being deteriorated by insect light containing ultraviolet rays.

  According to the first aspect of the present invention, the insecticidal effect toward the light source can be enhanced with the minimum amount of the insect attracting light source, and the insecticidal performance can be improved. Can provide.

  According to the invention of claim 2, in the invention of claim 1, the insect attracting effect can be further improved by irradiating the insect light by focusing on the specific irradiation area, and the insect outside the specific irradiation area. Invite you to not kill insects.

  According to the invention of claim 3, in the invention of claim 1 or 2, the protective layer of the reflecting member can further suppress the deterioration of the reflecting performance, and the dead body of the bombarded insect is placed on the surface of the reflecting member. Insects that are difficult to adhere and adhere to the surface of the reflecting member can be easily removed.

  According to the invention of claim 4, in the invention of any one of claims 1 to 3, the insecticidal performance by electric shock of the electric grid can be further enhanced.

  According to the invention of claim 5, in any one of the inventions of claims 1 to 4, it is possible to prevent the suspended installation surface of the electric shock insecticidal device from being deteriorated by insect light containing ultraviolet rays.

  A first embodiment of the present invention will be described with reference to FIGS.

  Reference numeral 1 in FIG. 1 and FIG. 2 indicates an electric shock insecticide. The electric shock insecticide 1 includes a main body 2.

  The main body 2 includes a pair of left and right side frames 3, an upper frame 4, a connecting rod 5, a back plate 6, a pair of left and right side frame covers 7, and an upper cover 8, as shown in FIGS. I have.

  Specifically, the side frame 3 has a quadrangular shape as shown in FIG. These left and right side frames 3 are arranged in parallel at a predetermined interval (see FIG. 3), and are represented by one side frame 3 shown in FIG. 2 and FIG. As shown, it has a cut and raised piece 3a and a fitting groove 3b. The cut and raised piece 3a is cut and raised inside the side frame 3, and the fitting groove 3b is formed by the cut and raised trace.

  The upper frame 4 forms the top plate of the main body 2, is fixed to the upper ends of the pair of side frames 3 by screws or the like, and is mounted across the left and right side frames 3 as shown in FIG. Yes. As shown in FIGS. 4 and 5, the upper frame 4 has a front flange 4 a bent upward from its front edge and a rear flange 4 b bent upward from its rear edge.

  The connecting rod 5 is made of a bar having a U-shaped cross section, and both longitudinal ends thereof are fitted in the fitting grooves 3b of the side frame 3 and screwed to the cut and raised pieces 3a. Thereby, the left and right side frames 3 are connected by the connecting rod 5.

  The back plate 6 extends in the left-right direction, and has fixed portions 6a (only the fixed portion at one end is shown in FIGS. 2 and 4) at both ends thereof. The back plate 6 is attached to the left and right side frames 3 by screwing these fixing portions 6 a to the side frames 3. The upper edge 6b of the back plate 6 is bent forward, and the upper edge 6b is in contact with the lower surface of the rear edge of the upper frame 4 as shown in FIG. The back plate 6 attached as described above covers the connecting rod 5 from the rear side.

  The left and right side frame covers 7 are fitted to the side frames 3 from the outside, and are screwed to the side frames 3.

  As shown in FIG. 2, the shape of the upper cover 8 viewed from the end surface is a curved shape, and thus has, for example, a bowl-like appearance. The shape may be square. The upper cover 8 is attached to the upper frame 4 so as to cover the upper frame 4 from above by being screwed to the front flange 4 a and the rear flange 4 b of the upper frame 4.

  In the present embodiment, the upper cover 8 has left and right end plates 8a. However, the left and right ends of the upper cover 8 are opened by omitting these end plates 8a, and the side frame cover 7 is formed in a size that can cover the opened end of the upper cover 8, and this side frame. The upper part of the cover 7 may be fitted to the left and right ends of the upper cover 8.

  The main body 2 having the above structure is closed at the upper surface by the upper frame 4, both side surfaces are closed by the side frame 3 and the side frame cover 7, and the rear surface is closed by the back plate 6. Each is shielded from light. As shown in FIG. 2, the interior of the main body 2 is partitioned into an upper chamber 2 a above the upper frame 4 and a lower chamber 2 b below the upper frame 4 with the upper frame 4 as a boundary.

  The electric shock insecticidal device 1 includes a main body 2 and a separate insect tray 11. The insect tray 11 is detachably attached to the main body 2 with the lower portion of the main body 2 closed. For this attachment and detachment, two L-shaped hooks 12 project from the lower inner surface of one side frame 3 as shown in FIG. 13 is protrudingly provided. At the same time, on one side of the insect tray 11 arranged so as to overlap the lower inner surface of the one side frame 3, as shown in FIG. The part through which the threaded portion of the decorative screw 15 inserted into and removed from the insect receiving tray 11 corresponding to the screw receiving bracket 13 is passed to the other side of the insect receiving tray 11 disposed so as to overlap the lower inner surface of the other side frame 3 (Not shown) is provided.

  The insect receiving tray 11 is shown in FIGS. 1 and 2 by hooking the locking hole 14 to the hook 12 and screwing the decorative screw 15 upward into the portion and screwing it into the screw receiving bracket 13. Thus, it is supported at the lower part of the main body 2. And the insect receiving tray 11 is provided so that it can remove from the main body 2 by the procedure reverse to this attachment.

  In a state where the insect catcher 11 is mounted on the main body 2, the front edge of the insect catcher 11, the front edges of the left and right side frames 3 covered with the side frame cover 7, and the upper frame 4 covered with the upper cover The front flange 4a is arranged to be continuous at a right angle to each other. Thereby, the main body 2 is in a state where the front surface is opened, more precisely, the front surface of the lower chamber 2b is opened.

  As shown in FIGS. 1 and 2, a protective member 21 is disposed in the lower chamber 2b so as to cover the opened front surface. The protection member 21 is formed in a lattice shape by combining metal bars vertically and horizontally, for example, so that flying insects can pass through. The upper and lower ends of the end metal rod 21a are bent in the rearward direction at the left and right ends of the protective member 21, and the upper and lower ends have a fixing portion 21b (see FIG. 2) at the tip. Yes. The protective member 21 is detachably supported on the front surface portion of the main body 2 by fixing these fixing portions 21b to the left and right side frames 3 with removable screws or the like.

  As shown in FIGS. 1 and 2, a reflecting member, for example, a reflecting plate 25 is disposed in the main body 2, specifically in the lower chamber 2b. The reflection plate 25 is disposed behind the protection member 21, and in the case of the present embodiment, the reflection plate 25 is disposed near the back plate 6 at the rear of the lower chamber 2b. The width W1 (refer FIG. 5) of the left-right direction of the reflecting plate 25 is wider than the diameter W2 (refer FIG. 2) of the attracting light source mentioned later.

  Each of the reflection plates 25 has fixing pieces 25a bent forward from the upper edges of both end portions in the width direction (left-right direction). By fixing these fixing pieces 25 a to the upper frame 4 with screws or the like, the reflecting plate 25 is supported in a state of being suspended from the upper frame 4. As shown in FIG. 6, the portions 25b on the left and right ends of the reflecting plate 25 are bent obliquely forward with respect to the central portion 25c of the reflecting plate 25 located between these portions 25b.

  As shown in FIG. 1, the central portion 25 c of the reflection plate 25 is positioned so as to face directly behind an insect light source 31 described later when the electric shock insecticidal device 1 is viewed in front. At the same time, as shown in FIG. 1, the portions 25 b on the left and right end portions of the reflecting plate 25 are off to the right or left from the back of the insect light source 31 when the electric shock insecticidal device 1 is viewed from the front. On the other hand, it is located so as to face diagonally from the rear. Accordingly, the insect attracting light source 31 is projected on the central portion 25c of the reflecting plate 25 when the electric shock insecticidal device 1 is viewed in front, but is not projected on the portions 25b on the left and right end portions side of the reflecting plate 25.

  The central portion 25c of the reflection plate 25 is formed to be bent, and specifically, is bent so as to protrude forward as shown in FIG. By this bending, the central portion 25c has a V-shaped cross section with a small protrusion height to the front side, but the cross section may be U-shaped or arc-shaped in addition to the V-shaped.

  The configuration of the reflector 25 having the bent central portion 25c prevents the light incident on the central portion 25c from the front side from being reflected back to the insect attracting light source 31 through the incident light path. Therefore, it is preferable to increase the utilization efficiency of the light emitted from the insect attracting light source 31. However, the central portion 25c may not be bent. Further, in the case of the bent central portion 25c, the convex portion may be formed on the rear side instead of the convex portion on the front side.

  As shown in FIG. 7, the reflection plate 25 includes a base material 26, a reflective surface 27 made of a reflective layer laminated on the surface of the base material 26, and a protective layer 28 laminated on the reflective surface 27. ing. The base material 26 is made of metal, and the reflection surface 27 is provided by vapor deposition metal or the like. The protective layer 28 is formed of a light-transmitting coating layer made of a light-transmitting material that is more slippery than the reflecting surface 27, for example, transparent titanium oxide that exhibits a photocatalytic action.

  As shown in FIG. 2, an insect light source 31 is disposed in the main body 2 so as to be positioned between the reflecting plate 25 and the protection member 21. Therefore, the insect attracting light source 31 is disposed in front of the reflecting plate 25. The insect light source 31 is a light bulb type fluorescent lamp with a ballast (not shown) built therein, and emits ultraviolet light (insect light) including a wavelength of 352 nm from the bulb 31a. The ballast is not a combination of an iron core and a coil, but a combination of a plurality of electronic components on a circuit board, and an outer shell between the valve 31a and the base 31b positioned above the valve 31a. Built in the part 31c.

  A socket 32 for supporting the insect light source 31 is fixed to the bracket 33. As shown in FIGS. 1, 3, and 5, the bracket 33 is positioned at the center of the upper frame 4 in the width direction and is fixed to the upper surface of the upper frame 4. As shown in FIG. 2, the socket 32 penetrates the upper frame 4 and protrudes into the lower chamber 2b. Accordingly, the insect attracting light source 31 is hung on the upper frame 4 through the socket 32 in a standing posture in which the bulb 31a is disposed below the base 31b by screwing the base 31b upward into the socket 32. The lower chamber 2b is in a state.

  In the case of the present embodiment, for example, the insect light source 31, the socket 32, and the bracket 33 are attached so that the insect light source 31 can be attached and detached without inserting the operator's hand deeply into the main body 2 with the protection member 21 removed. It is arranged close to the protection member 21. The insect light source 31 can be exchanged from below the main body 2 with the insect tray 11 removed.

  Moreover, the code | symbol 34 in FIGS. 1-4 has shown the cylindrical cover. The cover 34 is covered over the socket 32 and the outer portion 31 c of the insect light source 31. This cover 34 can prevent waterproofing of the attachment portion of the insect light source 31 and invasion of insect dead bodies.

  As shown in FIG. 2, the main body 2 is provided with a lightning grid 35 located between the insect light source 31 and the reflector 25, in other words, in front of the reflector 25 and behind the insect light source 31. The electric shock grid 35 is sufficiently insulated from the lure light source 31 disposed in front of it, and is also sufficiently insulated from the reflector 25 disposed later.

  As shown in FIG. 5, a pair of front and rear electric shock grids 35 are provided, and are formed to extend straight in the width direction of the main body 2. Both ends of these electric shock grids 35 are supported by a pair of left and right insulators 36 as shown in FIGS. The insulator 36 is attached to the upper frame 4 so as to penetrate both left and right ends. Therefore, the electric shock grid 35 is supported at both ends by the upper frame 4 via the insulator 36, and is thus suspended from the lower chamber 2 b of the main body 2.

  In the upper chamber 2a isolated from the lower chamber 2b of the main body 2, a high voltage applying device such as a high voltage transformer 41 is disposed. The high voltage transformer 41 is fixed to the upper surface of the central portion of the upper frame 4 in the left-right direction. By arranging the high voltage transformer 41 at this position, the dead body of the insects to be killed by electric shock is not attached, and when the electric shock insecticidal device 1 is suspended by a chain or the like, the weight balance is good and the electric shock insecticidal device 1 does not tilt left and right. This is preferable.

  The primary side wiring 42 shown in FIGS. 1 to 4 is supplied to the high voltage transformer 41, and the secondary side wiring 43 led out from the high voltage transformer 41 is connected to the electric shock grid 35. The high voltage to be applied is applied to the electric shock grid 35. The primary wiring 42 passes through the upper cover 8 and is fixed to the upper cover 8 with a waterproof cord stopper 44.

  In FIG. 1 and FIG. 3, reference numeral 45 indicates a power switch. A switch knob 45 a of the power switch 45 is disposed on the front side of the upper cover 8. Therefore, the power switch 45 is turned on / off from the outside of the upper cover 8, and power is supplied to the electric shock insecticidal device 1 by the on operation.

  1 to 5, reference numeral 47 indicates a suspension receiver. The suspension receivers 47 are fixed to the upper surfaces of the left and right ends of the upper frame 4 respectively. A lifting tool such as a metal chain is connected to the upper ends of these lifting tool receivers 47, and the electric shock insecticidal device 1 is installed in a state of being hung at the place of use by using this lifting tool.

  8A and 8B show an installation example of the electric shock insecticidal device 1. In these drawings, reference numeral 51 denotes a building, for example, a convenience store. The convenience store 51 has a door 52 that is opened and closed as a person enters and exits the store, and has a eaves-like eave 53 at a position higher than the door 52. The eaves 53 extend in the lateral direction of the convenience store 51, and the electric shock insecticidal device 1 is installed using a lifting tool 54, shifted from directly above the door 52. Thus, the opened front surface of the electric shock insecticide 1 installed under the eaves is located on the door 52 side, and the insect light passing through the opened front surface is projected toward the door side. ing.

  As shown in FIG. 2, the electric shock insecticide 1 includes an eaves-like light-shielding convex portion 49. In each drawing other than FIG. 2, the illustration of the light shielding convex portion 49 is omitted for convenience of explanation. The light-shielding convex portion 49 is attached to the upper side of the opened front surface of the main body 2, and prevents the light passing through the opened front surface from entering the eaves 53. Projected forward of the front face.

  When the lightning insecticidal device 1 is used with the insecticidal light source 31 turned on, the insecticidal light source 31 emits an insecticidal light around and below the insecticidal light source 31 and the insecticidal light directed directly forward from the insecticidal light source 31 (arrow C in FIG. 6). The light is projected to the outside of the main body 2 through the protective member 21 disposed on the open front surface of the main body 2. On the other hand, since the attracting light (indicated by an arrow D in FIG. 6) directed from the attracting light source 31 to the rear side is incident on the reflecting plate 25, it is reflected to the front side by the reflecting plate 25 and passes through the protective member 21. Light is projected outside the main body 2.

  In this way, it is possible to prevent the insect light directed toward the rear side of the insect light source 31 from being wasted by the reflector 25 and to project the light toward the front of the main body, so that the insect attracting effect is enhanced. In addition, since the attracting light source 31 is reflected on the reflecting surfaces 27 such as the portions 25b on both ends of the reflecting plate 25 on the rear side, the reflecting plate 25 becomes a pseudo secondary photogen. Thereby, since the magnitude | size of the light source seen from the insect near the door 52 of the convenience store 51 becomes apparently large, the insect attracting effect is enhanced.

  As the above-described increase in the amount of light and the apparent size of the light source can be improved, the insect attracting effect can be improved, and the performance of killing insects that are invited into the main body 2 and enter the lightning grid 35 can be improved. .

  Such an insecticidal effect is enhanced as the number of insect attracting light sources 31 is increased. However, even when the number of attracting light sources 31 is one as in the present embodiment, the attracting effect toward the attracting light source 31 is enhanced, and accordingly The insecticidal performance by electric shock by the electric shock grid 35 is improved. Note that most of the carcasses of insects killed by electric shock scatter around and are received by the insect tray 11 below.

  In addition, a large number of attracting light sources 31 are not required to ensure a large size of the light source viewed from the insects outside the main body 2, and the number of attracting light sources 31 used is minimized (one in this embodiment). it can. Thereby, cost can be reduced.

  At the same time, since the electric shock grid 35 is disposed only after the insect light source 31, the space in the front-rear direction required for arranging the electric shock grating 35 and the insect light source 31 is arranged on both sides of the electric shock grating 35. Compared with the configuration in which the lightning grid is arranged in an annular shape surrounding the surrounding of the insect light source, the half is sufficient. Therefore, although it is necessary to dispose the insect attracting light source 31 and the like with a predetermined insulation distance from the electric shock grid 35, the length in the front-rear direction of the main body 2 incorporating the electric shock grating 35 and the insect light source 31 is shortened. Thus, as the electric shock insecticide 1 can be compactly formed in the front-rear direction, further cost reduction can be achieved.

  Furthermore, since the reflecting surface 27 of the reflecting plate 25 is covered with the protective layer 28, it is possible to suppress the reflecting surface 27 from being fogged and the reflecting performance from being deteriorated. At the same time, since the protective layer 28 has high slipperiness, the dead bodies of insects scattered by electric shock insects and reaching the reflector 25 are difficult to adhere to the surface of the reflector 25 and adhere to the surface of the reflector 25. It is also easy to remove dead insect carcasses.

  Further, since the main body 2 of the electric shock insecticidal device 1 is provided with an eaves-like light-shielding convex portion 49, an insecticidal light passing through the opened front surface of the main body 2 obliquely upward by the light-shielding convex portion 49. Is blocked. Therefore, a part of the lure that contains ultraviolet rays emitted from the main body 2 of the electric shock insecticidal device 1 suspended under the eaves, for example, under the eaves, is prevented from deteriorating the eaves under the eaves. it can.

  Note that, as described above, the electric shock insect killer 1 can project the attracting light through the open front surface of the main body 2 to the irradiation area limited based on the size of the front surface. That is, as shown in FIG. 8A, the irradiation area when viewed from above is a narrow angle range α in the front-rear direction so as to be substantially along the front surface of the convenience store 51, and when the convenience store 51 is viewed in front. 8B is an area defined by an angle range β extending from just below the eaves 53 to the lower part of the door 52 as shown in FIG. In this way, by limiting the irradiation area, it is possible to limit the insects that are invited to light and are killed by electric shock in the main body 2 to the insects in the vicinity of the door 52.

  In other words, the attracting light is projected to an area other than the vicinity of the door 52, and the surrounding insects are not drawn and killed. As a result, the number of insects that are killed by electric shock is minimized, so that the number of discharge sounds that accompany electric shock is reduced, and the reflector 25 and insect light source by dead bodies of insects that have been killed by electric shock and scattered. The dirt of 31 is also reduced, which is advantageous in maintaining them.

  9 and 10A to 10C show a second embodiment of the present invention. The second embodiment differs from the first embodiment in the configuration of the reflector (reflecting member) in addition to the arrangement of the lure light source 31, the electric shock grid 35, and the high-voltage transformer 41, and the other configurations are the same as those in FIGS. 9 and 10A. It is the same as that of 1st Embodiment including the structure which is not shown by-(C). Therefore, the same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted. In the following description, FIG. 8B is referred to as necessary.

  As shown in FIG. 9, between the protective member 21 and the reflecting plate 25, the insect attracting light source 31 is disposed on the back side (rear side) in the lower chamber 2 b of the main body 2 toward the reflecting plate 25. The electric grid 35 is located in front of the insect light source 31 and is disposed between the insect light source 31 and the protection member 21. The high-voltage transformer 41 is disposed in the upper chamber 2a so as to be positioned in front of the electric grid 35 thus disposed.

  The reflector 25 disposed on the rear side of the electric grid 35 and the insect light source 31 has an oblique light distribution control unit 29. As shown in FIGS. 10A to 10C, the light distribution control unit 29 is a part that reflects incident light thereto obliquely downward, and is bent, for example, obliquely forward from the upper edge of the central part 25 c. ing. In order to provide such an oblique light distribution control unit 29, the upper and lower edges of the left and right fixing pieces 25 a are extended upward in accordance with the height of the light distribution control unit 29. It is bent from the part. In addition, the center part of the reflecting plate 25 in 2nd Embodiment is not bent and is flat. Except for the configuration described above, the configuration is the same as that of the first embodiment, including configurations not shown in FIGS. 9 and 10A to 10C.

  Therefore, also in the second embodiment, the same effect as that already described in the first embodiment can be obtained to solve the problem of the present invention.

  In addition, since the electric shock grid 35 is disposed in front of the lure light source 31, the distance between the electric shock grid 35 and the reflecting plate 25 is far greater than that of the first embodiment. Therefore, there is an advantage that it is advantageous in terms of maintenance of the reflector 25 that the dead bodies of the insects killed by the electric shock grid 35 reach the reflector 25 and are attached thereto.

  Furthermore, the insect attracting light source 31 is disposed closer to the reflecting plate 25 than in the first embodiment, and is disposed on the back side of the lower chamber 2b. Therefore, as the insect light that is directed obliquely upward from the insect light source 31 can be shielded by the upper frame 4 of the main body 2, the light shielding convex portion employed in the first embodiment can be omitted or even when the light shielding convex portion is used. There is an advantage that the protruding length can be shortened. In addition, since the attracting light source 31 is brought close to the reflecting plate 25, it is possible to reflect the attracting light with a high light intensity forward, which is advantageous in enhancing the attracting effect.

  In addition, the light distribution control unit 29 provided on the reflection plate 25 can reflect light incident thereon obliquely downward and project light from the open front surface of the main body 2, so that the main body 2 is opened. The light distribution to the irradiation area based on the size of the front surface can be ensured less in the upward direction and more in the obliquely downward direction. FIG. 8B shows an irradiation angle range β1 in which such light distribution control is taken into consideration. This point can contribute to shortening the protruding length even when the light shielding convex portion employed in the first embodiment can be omitted or even when the light shielding convex portion is used.

  In addition, as shown in FIG. 8 (B), it is possible to irradiate more insect light by focusing on a specific irradiation area, specifically, near the door 52. For this reason, there exists an advantage that the effect which invites the insect which exists in a specific irradiation area in the main body 2 can be improved, attracting the insect which is outside a specific irradiation area, and not killing an insect.

  FIG. 11 shows a third embodiment of the present invention. The third embodiment is different from the second embodiment in the configuration of the electric grid 35, and other than that, the third embodiment is the same as the second embodiment including the configuration not shown in FIG. Therefore, the same configurations as those of the second embodiment are denoted by the same reference numerals as those of the second embodiment, and description thereof is omitted.

  As shown in FIG. 11, the electric shock grid 35 disposed between the protective member 21 and the insect light source 31 disposed behind the bent member is bent in a substantially semicircular shape in plan view, and the insect light source 31 is arranged in the circumferential direction. Are arranged so as to surround about half a circle. Configurations other than those described above are the same as those in the second embodiment, including configurations not shown in FIG.

  Therefore, also in the third embodiment, the same effect as that already described in the second embodiment can be obtained to solve the problem of the present invention.

  In addition, according to the electric shock grid 35 having the above-described configuration, the distances between the respective parts and the insect light source 31 are substantially equal. For this reason, there exists an advantage that the possibility that the insect which is attracted in the main body 2 by the light projected on the irradiation area and flies around the insect light source 31 will be killed by the electric shock of the electric grid 35 is increased.
