<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG.1 and FIG.2 has each shown the perspective view and side sectional drawing of the humidifier of 1st Embodiment. In FIGS. 1 and 2, white arrows indicate the air flow. The humidifier 1 has a housing 2 that is installed on a floor surface in a living room and has a substantially elliptical horizontal cross section. A removable cover member 3 is attached to the back side of the housing 2.

  A sleeve portion 12 made of a transparent resin is provided on the peripheral edge of the upper surface of the housing 2. An operation unit 6 is provided on the front upper surface of the housing 2. The operation unit 6 has a plurality of buttons (not shown), and sets the operation of the humidifier 1 by a user operation. By operating each button, it is possible to instruct to turn on / off the humidifier 1, change the air volume of the blower 10, and turn on / off the ion generator 11.

  An inlet 20 and an outlet 5 are opened on the back and top surfaces of the housing 2, respectively. The blower outlet 5 is provided with a grill 5a and a protruding plate 13. The grill 5a (lattice-like member) is formed integrally with the casing 2, and is formed in a grid having a pitch of 3 mm or less. Thereby, the blower outlet 5 is formed in the magnitude | size which insects, such as a mosquito and a fly, cannot pass. The protruding plate 13 is provided at the center of the outlet 5 and protrudes upward.

  A plurality of suction ports 4 are opened in the cover member 3, and an insect trapping space 25 that allows the suction port 4 and the inflow port 20 to communicate with each other is formed between the cover member 3 and the back surface 2 a of the housing 2. The back surface 2a of the housing 2 facing the insect trapping space 25 is formed in black.

  A blower passage 7 that connects the inlet 20 and the outlet 5 is provided in the housing 2. A filter 8 (first filter), a humidifier 30, a blower 10, and an ion generator 11 are provided in the air passage 7 in order from the inlet 20 toward the outlet 5 (from upstream to downstream of the airflow).

The blower 10 is formed by a sirocco fan driven by a motor 10a, and sucks in an axial direction and exhausts in a circumferential direction.

  The filter 8 is formed by welding a polypropylene mesh to a rectangular frame having a plurality of rows and rows of windows formed of a synthetic resin such as ABS. The pitch of the mesh is 3 mm or less, and the mesh is formed in such a size that insects such as mosquitoes and flies cannot pass through. The filter 8 contains an insecticidal component.

The ion generator 11 has an electrode (not shown) that generates ions when a high voltage is applied, and the electrode faces the air passage 7. A voltage having an AC waveform or an impulse waveform is applied to the electrodes. When the applied voltage of the electrode is a positive voltage, positive ions mainly composed of H ⁺ (H ₂ O) m are generated, and when the voltage is negative, negative ions mainly composed of O ₂ ⁻ (H ₂ O) n are generated. Here, m and n are integers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odor components and surround them.

Then, as shown in the formulas (1) to (3), active species [· OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and produced on the surface of a microorganism or the like by collision. Destroy airborne bacteria. Here, m ′ and n ′ are integers. Therefore, sterilization and odor removal in the room can be performed by generating positive ions and negative ions and sending them out from the outlet 5.

_{^{H + (H 2 O) m}} + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ··· (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 · OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  Moreover, when positive ions and negative ions come into contact with the user's skin, hydroxyl groups (OH groups) adhere to the skin and the skin surface becomes hydrophilic. This makes it easier for water molecules to adhere to the skin surface and moisturizes the skin.

  The humidifying unit 30 includes a tank 35, a water tank 34, and a humidifying filter 33. The tank 35 is detachably provided by opening a lid (not shown) on the side surface of the housing 2 and stores water for humidification. The water tank 34 is provided on the bottom wall of the air passage 7 and is supplied with water from the tank 35 and held at a predetermined water level.

  The humidifying filter 33 is formed by holding a circular water absorbing material 32 by a holding portion 31 formed in a hollow disk shape of a resin molded product. The water absorbing material 32 is formed of a non-woven fabric having air permeability and water absorption. The holding portion 31 is pivotally supported on the housing 2 by a shaft portion 31a and is rotatably arranged.

  FIG. 3 shows a perspective view of the humidifying filter 33. A rack 31 b is formed on the outer peripheral surface of the holding portion 31. The rack 31b meshes with a pinion 37a (see FIG. 2) attached to a motor 37 (see FIG. 2) disposed in the housing 2. By driving the motor 37, the humidifying filter 33 rotates in the vertical plane.

  An opening 31c and a covering portion 31d are provided on both end surfaces of the holding portion 31 in the axial direction. The covering portion 31 d is formed in a partial circular shape and covers the water absorbing material 32. A plurality of openings 31c are opened in the non-formed portion of the covering portion 31d, and the water absorbing material 32 is exposed.

  The humidifying filter 33 is rotated by a motor 37 (see FIG. 2), and the water absorbing material 32 is immersed in the water tank 34 (see FIG. 2) through the opening 31c to absorb water. In addition, when the motor 37 is stopped, the covering portion 31d is immersed in the water tank 34 to avoid water absorption of the water absorbing material 32, and propagation of germs of the water absorbing material 32 is prevented.

  FIG. 4 shows a rear sectional view of the upper part of the housing 2 of the humidifier 1. A protruding portion 28 that protrudes outward (to the cover member 3 side) with respect to the inflow port 20 is provided at the upper back of the housing 2. The projecting portion 28 is formed to extend in the left-right direction, and a recess 28 a is formed in the center portion in the left-right direction on the lower surface of the projecting portion 28.

  At the left and right end portions in the recess 28a, the induction lamp 21 is arranged so that the emission surface (not shown) faces obliquely downward. Thereby, the attracting light 21 faces the upper part of the insect trapping space 25 and is disposed above the suction port 4 of the cover member 3. The attracting lamp 21 has an ultraviolet light emitting diode (not shown) that emits ultraviolet light of about 365 nm that attracts insects such as mosquitoes.

  A plate-like reflecting portion 61 having reflecting surfaces 61a formed on both sides is suspended from a central portion in the left-right direction of the recess 28a. The reflection surface 61a is textured, and the light P1 emitted from the emission surface of the induction lamp 21 is diffusely reflected by the reflection surface 61a. The light P2 diffusely reflected by the reflecting surface 61a irradiates the insect trapping space 25 and is emitted into the living room through the suction port 4. Thereby, it can prevent that a user looks directly at the attracting light 21. FIG.

  FIG. 5 shows a front view of the cover member 3 as viewed from the inside (case 2 side). The cover member 3 has an engaging claw (not shown) that engages with an engaging hole (not shown) provided in the housing 2. Thereby, the cover member 3 is detachably attached to the housing 2. The cover member 3 is curved so as to protrude rearward, and a plurality (five in the present embodiment) of suction ports 4 are provided in parallel on the left and right ends. In addition, the suction inlet 4 may be one.

  The suction port 4 is formed in such a size that a circle having a diameter D of 5 mm enters the suction port 4 by being projected onto a predetermined surface. Thereby, an insect can be made to easily enter the trapping space 25 (see FIG. 2) through the suction port 4.

  Moreover, the suction inlet 4 is formed in the magnitude | size which projects on the arbitrary surfaces seen from all directions, and fits in the circle whose diameter D is 40 mm. Thereby, since the hand width | variety of an infant is about 40 mm or more, it can prevent an infant's hand approaching into the insect trapping space 25 (refer FIG. 2) via the suction inlet 4. FIG. Therefore, it is possible to prevent contact between the insect captured on the insect capturing sheet 51 described later and the hand of the infant.

  An insect capturing sheet 51 is disposed on the inner surface 3 a of the cover member 3. The insect catching sheet 51 is mounted by engaging holes 51 b with engaging portions 55 protruding from the four corners of the cover member 3. The insect trapping sheet 51 has an adhesive surface 51a provided with, for example, an acrylic adhesive on one surface of the housing 2 side.

  The cover member 3 is provided with an odor generating part 70 for generating an odorous substance that attracts insects on the inner surface 3a. Although there is no limitation in particular in an odor substance, For example, lactic acid can be mentioned. Mosquitoes can be easily attracted by lactic acid. In addition, as long as the installation place of the odor generating part 70 is in the insect trapping space 25, it is not limited to the inner surface of the cover member 3 and may be provided on the back surface 2 a of the housing 2.

  In the humidifier 1 configured as described above, when the operation of the humidifier 1 is instructed by the operation of the operation unit 6, the blower 10 and the motor 37 of the humidifier 30 are driven. By driving the blower 10, the air in the room flows into the insect trapping space 25 through the suction port 4. The humidifying filter 33 is rotated by driving the motor 37 and is absorbed by the water absorbing material 32.

  The air that flows into the insect trapping space 25 flows into the air passage 7 from the inlet 20 of the housing 2. At this time, large dust in the air is collected by the filter 8. The air that has passed through the filter 8 passes through the water absorbing material 32 through the opening 31c of the humidifying filter 33 and contains moisture. In addition, the air flowing through the blower passage 7 on the exhaust side of the blower 10 includes ions generated by the ion generator 11. And the air containing a water | moisture content and ion is sent out from the blower outlet 5. FIG.

  Thereby, the air in a living room circulates and it can disinfect and deodorize by ion. Moreover, the absolute humidity in the living room can be increased to prevent infectious diseases such as influenza that are transmitted by air.

  Further, the attracting lamp 21 is turned on at a predetermined time, and the light emitted from the attracting lamp 21 is diffusely reflected toward the suction port 4 by the reflecting surface 61a. Thereby, the insect is attracted to the insect trapping space 25 through the suction port 4 by the emitted light of the attracting lamp 21 and the odor component of the odor generating part 70. Insects that have entered the trapping space 25 are captured by the trapping sheet 51 and are killed by the insecticidal components contained in the filter 8 and accumulated in the trapping space 25. Therefore, it is possible to prevent insect-borne infections.

  At this time, the filter 8 prevents insects from entering the humidifying unit 30. Thereby, since insects are not captured by the water tank 34 and the water absorbing material 32 of the humidifying unit 30, insect decay due to water contained in the water tank 34 and the water absorbing material 32 can be prevented.

  Ultraviolet light from the induction lamp 21 enters the housing 2 through the inlet 20 and the filter 8, and the humidifying filter 33 can be sterilized. A hole 28b facing the inside of the housing 2 may be provided in the protruding portion 28 so that the humidifying filter 33 is irradiated with ultraviolet rays.

  It is known that insects such as mosquitoes prefer black. Since the back surface 2a of the housing 2 (region facing the insect trapping space 25) is formed in black, the insect attracted to the vicinity of the cover member 3 can easily enter the insect trapping space 25 through the suction port 4. Can do. Moreover, since the insect catching sheet 51 is formed in black, the insect that has entered the insect catching space 25 can be easily attracted onto the insect catching sheet 51.

  Furthermore, insects such as mosquitoes are known to prefer moisture and moisture. For this reason, insects are attracted to the water stored in the water tank 34 of the humidifying unit 30, and insects such as mosquitoes can easily enter the trapping space 25.

  According to this embodiment, the humidification part 30 is distribute | arranged to the ventilation path 7 in the housing | casing 2 which opens the inflow port 20 and the blower outlet 5, and the filter 8 (1st filter) is distribute | arranged to the inflow port 20. FIG. A cover member 3 that opens the suction port 4 is attached to the housing 2, and an insect capturing sheet 51 is disposed in the insect capturing space 25 between the housing 2 and the cover member 3. Thereby, the air in the living room flows into the insect capturing space 25 from the suction port 4, is captured by the insect capturing sheet 51 and is collected by the filter 8. Thereafter, the air flows through the air passage 7, is humidified by the humidifying unit 30, and is sent out from the outlet 5.

  For this reason, it is possible to increase the absolute humidity in the living room to prevent infectious diseases that are transmitted by air and to prevent insect-borne infectious diseases, thereby improving the preventive effect of infectious diseases. In addition, insects can be prevented from entering the humidifying unit 30 by the filter 8, and insect decay due to water contained in the humidifying unit 30 can be prevented.

  Moreover, since the filter 8 is made of a mesh and the mesh pitch is 3 mm or less, it is possible to reliably prevent an insect such as a mosquito from entering the humidifying unit 30.

  Moreover, since the filter 8 contains an insecticidal component, insects that have entered the insect trapping space 25 are killed, and more insects can be captured.

  In addition, since the suction port 4 is projected onto an arbitrary surface and enters a circle having a diameter of 40 mm, the hand of the infant can be prevented from entering the insect trapping space 25. Therefore, contact between the insect captured on the insect catching sheet 51 and the hand of the infant can be prevented, and the hygiene of the humidifier 1 can be improved.

  Moreover, the grill 5a (grid-like member) is provided in the blower outlet 5, and the grid pitch of the grill 5a is 3 mm or less. For this reason, it is possible to prevent insects from entering the humidifying unit 30 from the air outlet 5, and to more reliably prevent insect decay due to water contained in the humidifying unit 30.

Other parts are the same as those in the first embodiment.

  The HEPA filter 9 is provided between the filter 8 and the humidifying unit 30. The HEPA filter 9 is formed by welding a frame material 9b by hot melt so as to cover the filter medium 9a, and can collect dust smaller than the filter 8. Therefore, for example, the HEPA filter 9 can collect fine dust in the air containing fine particulate matter such as PM2.5 having a particle size smaller than a predetermined particle size (for example, 3 μm).

  According to this embodiment, the same effects as those of the first embodiment can be obtained. Moreover, since the HEPA filter 9 collects dust that is smaller than the filter 8, the indoor air can be further purified.
