The insect trapping sheet 51 has an adhesive surface 51a provided with, for example, an acrylic adhesive on one surface on the housing 2 side.

Further, on the back surface 3a of the decorative panel 3, an odor generating portion 70 that generates an odorous substance that attracts insects is provided. The odorous substance is not particularly limited, and examples thereof include lactic acid. Insects such as mosquitoes can be easily attracted by lactic acid.

6 and 7 show a top sectional view of the blower 1. A drive device 35 for moving the decorative panel 3 in the front-rear direction is provided on the upper portion of the housing 2. The drive device 35 includes a motor 30 and a movable portion 31.

The movable portion 31 is provided with a protruding portion 33 projecting forward from the four corners of the rectangular ring-shaped frame 32, and a gear portion 34 projecting rearward from the central portion of the upper end. The protruding portion 33 is fitted into the hole portion 2d provided in the front surface 2b of the housing 2. It faces each engaging portion 55 on the back surface 3a of the decorative panel 3. Further, the protruding portion 33 is formed of a magnetic material, and a magnet 55a is provided on the rear end surface of each engaging portion 55. As a result, the engaging portion 55 is attracted to the protruding portion 33, and the decorative panel 3 is detachably attached to the housing 2.

A rack (not shown) is formed in the gear portion 34, and meshes with a pinion 30b attached to the shaft 30a of the motor 30. The movable portion 31 is guided to the hole portion 2d by the drive of the motor 30, and moves in the front-rear direction together with the decorative panel 3. A linear guide bearing may be provided in the hole 2d.

As a result, the decorative panel 3 reciprocates between the wide opening position of the insect trapping space 25 shown in FIG. 6 and the narrow closing position of the insect trapping space 25 shown in FIG. 7, and the volume of the insect trapping space 25 is changed. The decorative panel 3 is arranged in the closed position when the operation of the blower device 1 is stopped, and is arranged in the open position when the operation is started. Further, as will be described later, when an insect enters the insect trapping space 25, the decorative panel 3 moves backward from the open position to the closed position.

In the closed position, a part of the suction port 4 is covered by the side wall of the housing 2. Since the decorative panel 3 is attached to the housing 2 via the magnet 55a, the decorative panel 3 is attached to the housing 2 when the decorative panel 3 inserted into the suction port 4 is sandwiched between the moving decorative panel 3 and the housing 2. Drop out of 2. Thereby, the safety of the blower 1 can be improved.

FIG. 8 is a block diagram showing the configuration of the blower device 1. The blower 1 has a control unit 100 that controls each unit. An operation unit 46, a blower 10, an ion generator 11, an attraction light 21, an illuminance sensor 41, a motor 30, an insect catching sensor 43, a storage unit 44, and a display unit 45 are connected to the control unit 100.

The storage unit 44 stores the control program and control data of the blower device 1, and temporarily stores the calculation result and the like by the control unit 100.

In the blower device 1 having the above configuration, when the operation of the blower device 1 is instructed by the operation of the operation panel 6, the drive device 35, the blower 10 and the ion generator 11 are driven. The decorative panel 3 is arranged at the open position by the drive of the drive device 35, and the air in the living room flows into the insect trapping space 25 through the suction port 4 by the drive of the blower 10.

When the attraction light 21 is turned on, the emitted light of the attraction light 21 is diffusely reflected by the reflecting surface 61a toward the suction port 4. As a result, the insects are attracted by the light leaking from the suction port 4, and the insects approaching the suction port 4 are sucked into the insect trapping space 25.

The air that has flowed into the insect trapping space 25 flows into the air passage 7 from the inflow port 20 of the housing 2. At this time, the pre-filter 8 collects large dust in the air. Further, the HEPA filter 9 collects fine dust in the air including PM2.5 and the like. The air flowing through the air passage 7 on the exhaust side of the blower 10 contains ions generated by the ion generator 11. The air in which the dust is collected and contains ions is sent out from the air outlet 5. As a result, the air in the living room can be circulated and cleaned.

Further, when the insect trapping sensor 43 detects an insect that has entered the insect trapping space 25, the drive device 35 moves the decorative panel 3 rearward to narrow the insect trapping space 25. When the insect trapping space 25 becomes narrower, the amount of air sucked from the suction port 4 increases, and it becomes difficult for insects to escape from the insect trapping space 25. Further, since the insect catching sheet 51 and the insect are close to each other, the insect can be easily caught by the insect catching sheet 51. When the decorative panel 3 is arranged in the closed position, it moves forward and returns to the opened position.

When an insect is detected by the insect catching sensor 43, the decorative panel 3 may be reciprocated at predetermined intervals (for example, every 5 minutes) within a predetermined period (for example, several hours). As a result, the decorative panel 3 moves backward after waiting for a plurality of insects to enter the insect trapping space 25, and the insect trapping rate by the insect trapping sheet 51 can be improved.

Further, when the power saving operation is set by the predetermined operation of the operation unit 46, the monitoring by the insect catching sensor 43 is stopped by the illuminance sensor 41 until the ambient brightness becomes lower than the predetermined value. As a result, when the living room is bright, the movement of the decorative panel 3 by the drive device 35 is stopped, and the power saving of the blower device 1 can be achieved. On the other hand, when the living room becomes dark from evening to night, the movement of insects such as mosquitoes becomes active, so that the decorative panel 3 moves backward based on the detection result of the insect catching sensor 43. As a result, it is possible to suppress a decrease in the amount of insects caught. Instead of the illuminance sensor 41, a time measuring unit for measuring the time may be provided to stop the monitoring by the insect catching sensor 43 in the daytime.

According to this embodiment, an insect trapping space 25 having a suction port 4 facing sideways is formed between the front surface 2b of the housing 2 and the decorative panel 3, and the insect trapping sheet 51 is installed on the back surface 3a of the decorative panel 3. .. As a result, the insects sucked into the insect trapping space 25 from the suction port 4 can be captured by the insect trapping sheet 51. Further, since the insect catching sheet 51 is arranged on the back surface 3a of the decorative panel 3, the insect catching sheet 51 is not exposed on the outer surface of the blower 1, and the insect catching sheet 51 cannot be visually recognized from the front through the suction port 4. .. Therefore, it is possible to prevent infectious diseases by catching insects and reduce discomfort given to the user.

Further, since the display unit 45 for displaying the operation status is arranged at the front portion of the housing 2, the operation status can be easily confirmed when viewed from the front of the blower device 1.

Further, since the operation unit 46 for setting the operation of the blower device 1 is arranged at the front part of the housing 2, the blower device 1 can be easily operated from the front.

Further, since the decorative panel 3 is formed so as to be movable in the front-rear direction, the insect trapping space 25 can be narrowed at a predetermined time to reliably capture the insects in the insect trapping space 25.

Further, an insect catching sensor 43 for detecting insects in the insect catching space 25 is provided, and when the insects are detected by the insect catching sensor 43, the decorative panel 3 moves rearward to narrow the insect catching space 25. As a result, the movement of the decorative panel 3 is stopped when no insects have entered the insect trapping space 25, and the power saving of the blower device 1 can be achieved.

Further, an illuminance sensor 41 for detecting the ambient brightness is provided, and when the ambient brightness becomes lower than a predetermined value, the decorative panel 3 moves rearward based on the detection result of the insect trap sensor 43. As a result, it is possible to suppress a decrease in the amount of insects caught and further save power. Instead of the illuminance sensor 41, a time measuring unit for acquiring the time may be provided, and the decorative panel 3 may move rearward at night to narrow the insect trapping space 25.

Further, when the decorative panel 3 is reciprocated in the front-rear direction at a predetermined cycle, the decorative panel 3 moves backward after waiting until a plurality of insects enter the insect trapping space 25. Thereby, the catching rate of insects by the bug catching sheet 51 can be improved.

When the insect catching sensor 43 is omitted and the ambient brightness detected by the illuminance sensor 41 becomes lower than the predetermined value, the decorative panel 3 may be reciprocated at predetermined intervals (for example, every 5 minutes).
