(Embodiment 1)
FIG. 1 is a side sectional view showing a ventilation device 1 according to the present embodiment. FIG. 2 is a schematic front view showing the ventilator 1 in the present embodiment. The ventilation device 1 is attached through the wall surface of the room.

  As shown in FIGS. 1 and 2, the ventilator 1 has a housing 2 that includes a suction port 3 that exhausts indoor air and an exhaust port 4 that exhausts the sucked air.

  Inside the housing 2, there are provided an air passage 5 that communicates the suction port 3 and the exhaust port 4, and a motor 6 and a fan 7 that are provided in the air passage 5 and generate an airflow from the indoor side toward the outdoor side. ing.

  On the front surface of the housing 2, a panel-like suction port cover 8 formed with a larger area than the opening area of the suction port 3, a gaseous substance generating unit 9 for generating a gaseous substance that attracts mosquitoes, And a heat source 10.

  The suction port cover 8 is disposed with a gap 11 between the suction port cover 3 and the suction port 3. The suction port 3 is partitioned by four sides on the front surface of the housing 2. That is, when the ventilator 1 is viewed from the front, the suction port 3 has four parts: an upper side, a lower side, a left side, and a right side. That is, the suction port cover 8 forms gaps 11 in four directions on the front surface of the housing 2.

  The gaseous substance generating unit 9 is provided so as to cover the gap 11 outside the lower side of the suction port 3, and the gaseous substance is discharged from the gaseous substance generating unit 9 to the indoor side. Further, the heat source 10 is installed at the upper part of the outer periphery of the suction port cover 8. The gaseous substance generation unit 9 and the heat source 10 are not in contact with each other.

  In the above configuration, when the ventilator 1 is operated, an air flow from the indoor side toward the outdoor side is generated by the operation of the motor 6 and the fan 7, and the indoor air is ventilated. Moreover, the gaseous substance which has the effect of attracting mosquitoes is emitted from the gaseous substance generation part 9 to the indoor side. As the gaseous substance diffuses indoors, indoor mosquitoes that have detected a concentration gradient are attracted to the vicinity of the ventilator 1. The mosquito approaching the vicinity of the ventilation device 1 is further attracted to the vicinity of the gap 11 by detecting the heat of the heat source 10. Mosquitoes that have approached the vicinity of the gap 11 are sucked into the airflow from the indoor side toward the outdoor side, and are discharged from the exhaust port 4 to the outside through the inside of the air passage 5.

  In the present embodiment, the gap 11 formed by the lower side of the gap 11 formed between each of the four sides and the suction port cover 8 on the front surface of the housing 2 is covered with the gaseous substance generating unit 9. ing. Therefore, the indoor air is not discharged from the gap 11 but is discharged from the other gap 11. Therefore, the gaseous substance generated from the gaseous substance generating part 9 can be actively diffused in the room direction without being immediately discharged outside the room.

  As a result, mosquitoes can be attracted to the vicinity of the ventilator 1, and indoor flying insects can be efficiently discharged from the ventilator 1.

  Moreover, in this Embodiment, the gaseous substance produced | generated in the gaseous substance generation | occurrence | production part 9 was made into the air whose carbon dioxide concentration is 4.5%.

  Since mosquitoes can be detected from a long distance even with a slight carbon dioxide concentration gradient, even a small amount of carbon dioxide can exert an attracting effect over the entire room. Moreover, since the carbon dioxide concentration of 4.5% is at the same level as human breath, the effect of attracting mosquitoes can be further enhanced.

  In this way, attracting mosquitoes that target blood-sucking people, such as mosquitoes and human mosquitoes, that could not be sufficiently attracted by conventional insect trapping devices using a light source, to the outside of the ventilator 1 and discharge them outside the room. Can do.

  In the present embodiment, the gaseous substance generating unit 9 is provided on the lower side of the suction port 3.

  A gaseous substance containing carbon dioxide, which is effective for attracting mosquitoes, has a molecular weight larger than that of air, and therefore easily diffuses downward when released indoors. By providing the gaseous substance generating part 9 at the lower side of the suction port 3, the generated gaseous substance can be efficiently diffused into the room, and mosquitoes can be attracted to the vicinity of the ventilator 1.

  Further, in the present embodiment, the fan 7 is rotated and stopped alternately during the operation of the ventilator 1, the gaseous substance is released from the gaseous substance generator 9 when the fan 7 is stopped, and the gas is emitted when the fan 7 is rotated. It is also possible to operate without releasing the particulate matter.

  Thereby, the state where the concentration of the generated gaseous substance is temporarily high in the vicinity of the suction port 3 of the ventilation device 1 can be maintained. By attracting flying insects to the gaseous substance having a high concentration, flying insects gather near the suction port 3 and can be discharged from the ventilator 1.

  In particular, mosquitoes that target humans for sucking blood, such as Aedes albopictus, Aedes aegypti, and Culex pipiens, can be expected to have an increased attractiveness compared to the continuous occurrence by generating carbon dioxide intermittently. It has a particularly attractive effect on flying insects that are highly dangerous in terms of mediation.

  As a means for intermittently generating a gaseous substance by the operation method, for example, a solenoid valve and a timer (not shown) are provided, the solenoid valve and the fan have the same power source, and the solenoid valve is opened by timer control. It can be implemented by adopting a configuration in which the stop of the fan, the closing of the solenoid valve, and the operation of the fan are repeated alternately.

  In the present embodiment, the heat source 10 is provided on the upper part of the outer periphery of the suction port cover 8 that is not in contact with the gaseous substance generating unit 9.

  Mosquitoes sense the source of heat and have the property of trying to stop at an appropriate temperature. Therefore, the mosquito approaching the ventilation device 1 due to the attracting effect of the gaseous substance senses the heat source 10 and tends to approach the suction port 3 to stop. Thereby, the mosquitoes approaching the ventilator 1 are guided into the air passage 5 from the suction port 3 and can be efficiently discharged from the ventilator 1.

  As an appropriate temperature for stopping mosquitoes, the surface temperature of the heat source 10 is preferably 30 to 40 degrees, and more preferably 34 to 36 degrees.

When carbon dioxide is included as a gaseous substance, for example, a UV lamp, a photocatalyst, and an organic substance for decomposition may be provided, and the organic substance may be decomposed to generate carbon dioxide by irradiating the photocatalyst with UV light.

  In the present embodiment, the heat source 10 is provided at the upper part of the outer periphery of the suction port cover 8, but may be provided at other portions of the outer periphery of the suction port cover 8 that are not in contact with the gaseous substance generating unit 9. Since air is exhausted from a portion of the suction port 3 that is not covered with the gaseous substance generating unit 9, more mosquitoes are guided to the vicinity of the suction port 3 by providing more heat sources 10, and the mosquitoes are efficiently removed outdoors. Can be discharged.

  Note that the heat source 10 may be provided not only on the suction port cover 8 but also on the front surface portion of the housing 2 that is close to the suction port 3 that is not blocked by the gaseous substance generation unit 9. Thereby, the effect which guides a mosquito to the suction inlet 3 vicinity can be heightened.
