  However, in the conventional insect trap 1 as shown in FIG. 11 described above, since the opening 2a is only on the upper side, the entrance area of the attracted insect is not ensured, and the trapping paper 4 captures it. Insect carcasses that have fallen on the instrument bottom surface 2d without being collected easily, and the insect dead bodies that have fallen on the instrument bottom surface 2d by the arrangement of the attracting light source 3 and the insect trapping paper 4 are difficult to clean. The insect trap shown in Patent Document 1 has only a clearance between the upper fall prevention member and a clearance provided between the wall surface where the insect trap is installed and the light shielding member, as an entrance for the attracted insect, The entrance area of attracted insects is not large. The insect trap shown in Patent Document 2 has only a gap provided inside the opening as an entrance for attracted insects, and the entrance area for the attracted insects is not large enough. Since the visual shielding portion of the opening is translucent, there is a problem that the radiation efficiency of the attracting light to the outside of the device is poor.

  The present invention has been made in order to solve the above-described conventional problems, and efficiently emits attracting light to the outside of the instrument, and ensures a large entrance area for the attracted insects. It is an object of the present invention to provide an insect trap that is difficult to collect dead insects and that can be easily cleaned.

  In order to achieve the above object, the invention of claim 1 includes an attracting light source for attracting insects, an insect trapping paper for capturing insects, an opening on the upper side, and an attracting light source and trapping paper inside. In addition, the housing has an opening on the front surface (hereinafter referred to as a front opening) and a reflector for reflecting light from the attracting light source inside the housing. The light from the attracting light source is emitted directly or through the reflector or the housing through the front opening.

  According to a second aspect of the present invention, in the insect trap according to the first aspect, the insect trapping paper is provided on the inner surface side of the front surface of the housing, and the front opening is provided below the attracting light source and the insect trapping paper. is there.

  According to a third aspect of the present invention, in the insect trap according to the first or second aspect, the reflector is disposed so as to be inclined so that the lower end side thereof faces the front side.

  According to the invention of claim 1, since the opening is provided not only on the upper opening but also on the front surface, it is possible to increase the area of the entrance of the attracted insect, and thus the insect trapping power is improved. To do. In addition, since the light emitted from the attracting light source is emitted from the opening without going through the semi-transmissive member, it emits more attracting light than that emitted through the semi-transmissive member, and attracts insects. It is possible to increase the attractiveness.

  According to the invention of claim 2, when an insect that has been attracted to the insect trap from the upper opening and has entered is not captured by the insect trapping paper, the insect is released from the front opening to the outside of the instrument before being weakened at the instrument bottom. As a result, insect dead bodies are less likely to collect at the bottom of the instrument. Moreover, even when a foreign substance enters the inside of the instrument, the foreign substance is discharged from the front opening provided below the front surface, so that the structure is difficult to collect inside the instrument. Further, since the insect trapping paper is arranged in the vertical direction, no foreign matter accumulates on the trapping paper, and only the insect is captured.

  According to the invention of claim 3, since the inclined reflector is disposed so as to reduce the horizontal part area of the instrument bottom and to form this horizontal part on the front opening side, It becomes possible to collect at the instrument bottom near the front opening, and cleaning becomes easy. Moreover, it becomes possible to emit efficiently from the front opening by reflecting the attracting light on the reflecting plate.

  An insect trap according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an insect trap 1 according to the first embodiment. The insect trap 1 is an instrument that emits attracting light to the outside of the instrument, and attracts and captures the insect into the instrument by the attracting light. The insect trap 1 includes a substantially rectangular housing 2, an attracting light source 3 for attracting insects inside the housing 2, an insect capturing paper 4 for capturing the attracted insects, and lighting of the attracting light source 3. A protective cover 5 for housing the ballast is provided. The housing 2 has an opening 2a above, a front opening 2c below the front surface 2b, and insect trap paper 4 is provided on the inner surface side of the front surface 2b. The attracting light source 3 is oriented horizontally along with the lighting ballast and the protective cover 5, and is disposed near the front opening 2 c in the housing 2. The insect trap 1 is configured as a horizontal type, in which the attracting light source 3 is arranged in the horizontal direction to reduce the height of the instrument.

  By adopting such a configuration, the opening 2c is provided not only in the upper opening 2a but also in the front surface 2b, so that it is possible to increase the area of the entrance of the attracted insects. Power is improved. Moreover, since the light emitted from the attracting light source 3 is directly emitted to the outside from the openings 2a and 2c without passing through the semi-transmissive member, more attracting light is emitted than when emitted through the semi-transmissive member. The attraction to attract insects has been enhanced. Moreover, since the insect trap 1 of this Embodiment 1 is a horizontal type, its gravity center position is lower than a vertical type, and since it is hard to fall down, it can be stably installed as a floor-standing type insect trap.

  FIG. 2 shows an insect trap 1 according to the second embodiment. A protective cover 5 that houses the attracting light source 3 and the lighting ballast is located inside the housing 2, faces the front surface 2 b and the insect trap paper 4, and is disposed at substantially the same height. The front opening 2 c is provided below the attracting light source 3 and the insect trap paper 4. Other configurations are the same as those of the first embodiment.

  By adopting such a configuration, in addition to the same effects as those of the first embodiment, when an insect that has been attracted and invaded into the insect trap 1 from the upper opening 2a is not captured by the insect trap paper 4, the insect is Since it is released from the front opening 2c to the outside of the instrument before it weakens at the instrument bottom 2d, insect dead bodies are unlikely to collect on the instrument bottom 2d. Moreover, even when a foreign object enters the inside of the instrument, the foreign object is discharged from the front opening 2c provided below the front surface 2b and is difficult to collect inside the instrument. Further, since the insect trap paper 4 is arranged in the vertical direction, no foreign matter accumulates on the insect trap paper 4 and only insects are captured. Moreover, since the arrangement space of the insect trap paper 4 is not required in the depth direction of the instrument, the instrument shape can be made thin.

  FIG. 3 shows the number A of insects captured by a conventional insect trap and the number B of insects captured by the trap 1 of the second embodiment. For this measurement, the conventional insect trap and the insect trap 1 of Embodiment 2 were installed in the same room, and after a certain period of time, the number of insects A and B captured by each was measured. This measurement was repeated four times.

  From the measurement results shown in the figure, the number B of insects captured by the insect trap 1 of Embodiment 2 is larger than the number A of insects captured by the conventional trap, and the trapping power is improved. I understand. The reason why such a difference in effect occurs is that the insect trap 1 according to the second embodiment is not only capable of invading the attracted insects from the upper opening 2a but also from the front opening 2c, and the front opening. This is because the attracting light emitted from 2c improves the power for attracting insects compared to the conventional insect trap.

  FIG. 4 shows the insect fall rate C in the conventional insect trap and the insect fall rate D in the insect trap 1 of the second embodiment. In addition, the falling rate of insects in the instrument in the trap is the ratio of the number of dead insects falling in the instrument without being captured by the trap paper 4 to the number of insects captured by the trap paper 4 of the trap. It shall be represented by In addition to the measurement of the number of insects captured by the insect trapping paper 4 in the above trapping device, the insect falling rate in the instrument of the trapping device was falling in the instrument without being captured by the trapping paper 4 The number of insect carcasses was measured, and the insect falling rates C and D were calculated.

  From the measurement results shown in the figure, it can be seen that the insect fall rate D in the insect trap 1 of the second embodiment is lower than the insect fall rate C in the conventional trap. The reason why such a difference in effect occurs is that if the insect trap 1 of the second embodiment is not attracted to the insect trapping paper 4 when the insect that has been attracted and invaded into the insect trap 1 from the upper opening 2a is detected, This is because insect dead bodies are less likely to collect on the instrument bottom surface 2d because they are released from the front opening 2c before being weakened at the instrument bottom 2d.

  FIG. 5 shows an insect trap 1 according to the third embodiment. The housing 2 includes a reflecting plate 6 for reflecting light from the attracting light source 3 on the inner surface side of the instrument bottom surface 2d. The reflecting plate 6 is composed of a horizontal plane and an inclined surface, and the inclined surface is inclined and disposed on the instrument bottom surface 2d so that the lower end side faces the front front side. The angle of inclination of the reflecting plate 6 is set so that the light from the attracting light source 3 is reflected and emitted from the front opening 2c. The reflector 6 covers a lighting ballast (not shown) disposed on the appliance bottom surface 2d. Other configurations are the same as those of the second embodiment.

  With such a configuration, in addition to the same effects as those of the second embodiment, the horizontal area of the instrument bottom surface 2d can be reduced, and the reflector 6 is arranged so that the horizontal part is formed on the front opening 2c side. By installing, the insects that have fallen can be collected on the instrument bottom surface 2d near the front opening 2c, and cleaning becomes easy. In addition, it is possible to efficiently emit the attracting light from the front opening 2c by reflecting the reflecting light on the reflecting plate 6. In addition, in the case of the floor-standing type insect trap 1, since it is necessary to lower the position of the center of gravity in order to suppress the instrument falling, it is desirable to install the lighting stabilizer near the instrument bottom surface 2d. In that case, the reflector 6 provided on the appliance bottom surface 2d can also be used as a protective cover for the lighting ballast.

  FIG. 6 shows an insect trap 1 according to the fourth embodiment. The housing 2 is in the shape of a triangular prism composed of right and left sides that are substantially triangular, an upper opening 2a, a front surface 2b, a front opening 2c provided below the front surface 2b, and a back surface. It has a 5 plane configuration. Other configurations are the same as those of the second embodiment.

  By adopting such a configuration, in addition to the same effects as those of the second embodiment, the surface configuration of the housing 2 can be reduced, so that the material cost and the number of processing steps are reduced.

  FIG. 7 shows an insect trap 1 according to the fifth embodiment. An insect trap 1 of the fifth embodiment is a modification of the housing 2 of the insect trap 1 of the fourth embodiment. The housing 2 is configured such that the cross-sectional shape of the front surface 2b is a convex curved surface facing forward, and an acute angle is not formed between the upper surface and the front surface 2b. Other configurations are the same as those of the fourth embodiment.

  By adopting such a configuration, in addition to the same effects as those of the fourth embodiment, the insect trap 1 does not have a sharp portion in the instrument shape, has a safe instrument shape, and has a soft design.

  FIG. 8 shows the insect trap 1 according to the sixth embodiment. A substantially rectangular louver 7 is disposed in the upper opening 2 a of the housing 2, and the louver 7 has a longitudinal direction in the width direction of the housing 2, and the upper opening 2 a from the upper direction of the front of the instrument. It is arranged at an angle so as to block the field of view through the instrument. Other configurations are the same as those of the second embodiment.

  By adopting such a configuration, in addition to the same effects as in the second embodiment, the inside of the instrument becomes difficult to be seen from the outside without impairing the ability of the insect trap, so that a person in the vicinity where the trap is installed It is possible to make a design that does not know that it is an insect trap. In addition, it is possible to prevent foreign objects from being thrown into the instrument due to mischief and the like, and to prevent damage to the attracting light source due to foreign objects.

  FIG. 9 shows an insect trap 1 according to the seventh embodiment. A substantially rectangular louver 7 is disposed in the front opening 2c of the housing 2. The louver 7 has a longitudinal direction that is the width direction of the housing 2, and the front opening 2c from the upper front of the instrument. It is arranged at an angle so as to block the field of view through the instrument. Moreover, the insect trap paper 4 is arrange | positioned by the inner surface side of the instrument bottom face 2d. Other configurations are the same as those of the second embodiment.

  By adopting such a configuration, in addition to the same effects as in the second embodiment, the louver 7 makes the insect trap paper 4 difficult to see from the outside and hides the trapped insect. Further, since the insect trap paper 4 is arranged on the instrument bottom surface 2d, the insect trap paper 4 captures insects that have fallen on the instrument bottom surface 2d. Can be cleaned.

  FIG. 10 shows an insect trap 1 according to the eighth embodiment. The front surface 2b of the housing 2 is configured such that the lower end portion serves as a rotation axis and the upper end portion rotates to open and close. Roller catches 8 are disposed inside the housing 2 near the front surface 2b and the right side surface of the housing 2 and inside the housing 2 near the front surface 2b and the left side surface of the housing 2, respectively. The housing 2 is held by the roller catch 8 with the front surface 2b closed. Moreover, the insect trap 1 is provided with a magnet 9 on the inner surface of the front surface 2b and on the insect trap paper 4, and the trap paper 4 is fixed by being sandwiched between the magnet 9 and the front surface 2b. Furthermore, rubber feet 10 are provided near the four corners on the outer surface side of the instrument bottom surface 2d, and a gap is formed between the instrument bottom surface 2d and the installation surface.
