Description

  The present invention relates to a water crushing negative ion generator, and more particularly to a water crushing negative ion generator that generates fine mist.

  Conventionally, air cleaners have been widely used in modern society, and their functions and types are diverse. For example, there are various types of air purifiers such as a filter type, a corona discharge type (plasma generation), and an ion / ozone generation type. Further, even if attention is paid to the effect of the air cleaner, there are those for the purpose of removing dust and dust, those for the purpose of deodorization and deodorization, and those for the purpose of sterilization.

  These air purifiers are all for maintaining a comfortable and healthy air environment, and are widely used particularly as a measure against viruses such as influenza in recent years and a measure against hay fever.

  By the way, in order to realize a comfortable air environment, the humidification function is regarded as important as well as the air purification function. Humidification is especially effective for dry measures and influenza measures in winter. As an air purifier having a humidifying function, there is an air purifier that generates negative ions using the Leonard effect and performs air cleaning.

  In other words, the water stored in the air purifier is crushed to generate negative ions, and comes into contact with the air sucked into the air purifier to adsorb and collect foreign substances. A water-crushing negative ion generator that performs this function is known.

  For example, in the invention described in Patent Document 1, air sucked into an air purifier is brought into contact with fine water droplets, and fine particles and microorganisms in the air are removed by an adsorption effect of mist particles. In the present invention, water is transferred upward by the inner guide portion having a funnel shape, and the transferred water is injected from a water injection nozzle connected to the upper end of the inner guide portion. It collides with the inner wall of the gas generator to generate negative ions, and comes into contact with the air sucked into the air purifier to adsorb and collect foreign matter.

  Embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the water fracture type negative ion generator 10 according to the present embodiment includes an operation unit 12 on the upper surface of a case 11. The operation unit 12 operates the water-breaking negative ion generator 10. That is, when the operation unit 12 is operated, a drive unit provided inside the water-breaking negative ion generator 10 is operated. By generating fine mist and bringing the air sucked from the air inlet 13 into contact with the fine mist, clean air is discharged from the air outlet 14 into the room.

(Explanation of the operation of the water crushing negative ion generator 10)
The drive unit described above includes a drive motor 23 having a substantially vertical rotating shaft 24 as shown in FIG. The rotating shaft 24 is for rotating a sirocco fan 22 which will be described later. By rotating the sirocco fan 22, an air flow is generated inside the water-smashing negative ion generator 10.

  A spiral cylinder 31 is provided around the sirocco fan 22 as shown in FIG. Inside the spiral cylinder 31 is formed a positive pressure chamber 32 that is brought into a positive pressure state by the air sent from the sirocco fan 22. As will be described later, the positive pressure chamber 32 communicates with the lower mist generating chamber 42 through a plurality of openings provided on the lower surface of the spiral cylinder 31. For this reason, when the sirocco fan 22 rotates and the positive pressure chamber 32 is in a positive pressure state, air flows into the lower mist generating chamber 42 through the plurality of openings.

  The mist generating chamber 42 is a space for generating fine mist, and is a space formed inside the spiral cylinder 37 as shown in FIG. The mist generation chamber 42 is provided so as to cover the vicinity of the upper end of the conical cylinder 26 as shown in FIG.

  In the water crushing negative ion generator 10 according to the present embodiment, the air flows into the mist generation chamber 42 so that the air that has flowed in comes into contact with the fine mist generated in the mist generation chamber 42. Yes.

  The generation of the fine mist in the mist generating chamber 42 is performed by sucking up water by centrifugal force when the conical cylinder 26 rotates and causing the sucked water to collide with the peripheral wall 38 of the spiral cylinder 37.

  That is, the conical cylinder 26 is fixed to the rotary shaft 24 described above below the sirocco fan 22 and rotates together with the sirocco fan 22 when the drive motor 23 rotates.

  When the conical tube 26 rotates, as shown in FIG. 2, the lower end of the conical tube 26 is submerged in the water of the water tank 16, so that water is sucked up from the lower opening 30 provided at the lower end, Water is wound up along the inner peripheral surface of the cylinder 26.

  The water thus wound up by the conical cylinder 26 is diffused and discharged from a diffusion hole 28 (see FIG. 4) provided near the upper end of the conical cylinder 26. The diffused and released water collides with the peripheral wall 38 of the spiral cylinder 37 inside the mist generating chamber 42. In this way, fine mist is generated in the mist generating chamber 42 by colliding and crushing the water sucked up by the conical cylinder 26.

  Here, as described above, since the positive pressure chamber 32 and the mist generation chamber 42 communicate with each other, the air in the positive pressure chamber 32 flows into the mist generation chamber 42 and comes into contact with the fine mist generated in the mist generation chamber 42. . And it is formed so that the air which contacted this fine particle mist flows out of the mist production | generation chamber 42 from the bottom part of the spiral cylinder 37, and is discharged | emitted from the blower outlet 14 outside as shown in FIG.

(Water tank 17)
The water supply tank 17 is for supplying water to the water tank 16 described above, and is provided in the case 11 of the water crushing negative ion generator 10 as shown in FIG.

  This water supply tank 17 is set inside the water supply tank cover 15 shown in FIG. 1, and can be removed from the case 11 by pulling up after removing the water supply tank cover 15. By removing the water supply tank 17 in this way, water can be supplied with water.

  On the other hand, when the water supply tank 17 is attached to the case 11, the water supply tank 17 is set at the upper end position of the water level maintaining shaft 19 as shown in FIG. 2. The water crushing type negative ion generator 10 according to this embodiment can keep the water level of the water tank 16 constant by setting the water supply tank 17 in this way.

  That is, as shown in FIG. 2, the water supply tank 17 is a sealed container having an opening 18 below, and the opening 18 is provided at a position lower than a predetermined water level W. For this reason, when the water supply tank 17 is set in the case 11, the water is discharged to the water tank 16 side until the negative pressure in the upper part of the water supply tank 17 becomes close to atmospheric pressure. When the water level of the water tank 16 reaches a predetermined water level W, the negative pressure at the upper part of the water supply tank 17 is formed so as to be balanced with the atmospheric pressure. It has come to droop.

(Configuration of drive unit)
Next, the configuration of the drive unit described above will be described.

  As shown in FIG. 3, the drive unit includes a drive motor 23 having a substantially vertical rotation shaft 24, a sirocco fan 22 connected to the rotation shaft 24 of the drive motor 23 and rotating, and the drive motor 23 described above. The fixed base 20, the conical cylinder lid 25 and the conical cylinder 26 fixed to the rotating shaft 24, the spiral cylinder 31 provided so as to cover the sirocco fan 22, and the vicinity of the upper end of the conical cylinder 26. And a spiral cylinder 37 provided so as to cover.

  Thus, since the sirocco fan 22, the conical cylinder lid 25, and the conical cylinder 26 are fixed to the rotating shaft 24 of the drive motor 23, when the drive motor 23 is rotationally driven, the conical cylinder lid 25 and the conical cylinder 22 together with the sirocco fan 22 are provided. The cylinder 26 is configured to rotate.

  Here, as shown in FIG. 4, a plurality of diffusion holes 28 penetrates in the vicinity of the uppermost portion 27 of the conical cylinder 26, and the water sucked up when the conical cylinder 26 sucks up the water. Are diffused and discharged radially from the diffusion hole 28. That is, the conical cylinder lid 25 covers the upper surface of the conical cylinder 26 so that the water that has reached the upper end of the conical cylinder 26 is blown in the direction of the diffusion hole 28.

  Then, the diffused and released water collides with the peripheral wall 38 (see FIGS. 6 and 7) of the spiral cylinder 37, and fine mist is generated.

  In the present embodiment, the diameter of the lowermost portion 29 of the conical cylinder 26 is 20 mm, and the diameter of the uppermost portion is 55 mm. The distance from the lowermost portion 29 to the uppermost portion of this conical cylinder 26 is 80 mm.

(Swirl cylinder 31)
The spiral cylinder 31 is provided around the sirocco fan 22 to form a positive pressure chamber 32, and is a bottomed cylindrical member surrounded by a side wall 36 as shown in FIG.

  As shown in FIG. 5, a central opening 34 is provided at the center of the bottom of the spiral tube 31 so as to communicate with the lower part.

  Further, as shown in FIG. 5, a winding wall portion 33 wound in the rotational direction D of the sirocco fan 22 is formed inside the side wall 36 of the spiral cylinder 31.

  A plurality of peripheral holes 35 are provided between the winding wall portion 33 and the side wall 36.

  Since the spiral cylinder 31 is formed as described above, a part of the wind generated by the sirocco fan 22 passes through the central opening 34 to the lower mist generating chamber 42 and the remaining wind is passed through the winding wall. It passes between the parts 33. The flow of the wind passing through the winding wall portion 33 increases as the flow path is narrowed, and finally passes through the peripheral hole 35 to escape to the mist generating chamber 42.

(Spiral cylinder 37)
The spiral cylinder 37 is provided around the conical cylinder 26 to form a mist generating chamber 42, and is a cylindrical member surrounded by a peripheral wall 38 as shown in FIG.

  As shown in FIG. 6, a slope plate 39 is provided inside the peripheral wall 38 of the spiral cylinder 37.

  As shown in FIG. 7, the slope plate 39 forms a spiral slope that gradually decreases in the rotational direction D of the sirocco fan 22, and as shown in FIG. 6, the peripheral wall 38 of the conical cylinder 26 is formed. The uppermost portion 40 and the lowermost portion 41 of the slope are provided so as to make a round around the inner side.

  For this reason, the wind that has flowed from the positive pressure chamber 32 to the mist generating chamber 42 flows on this slope, and the flow velocity of air can be increased.

  The spiral cylinder 37 is formed so that the water diffused and released from the diffusion hole 28 collides with the peripheral wall 38 by covering the periphery of the diffusion hole 28 of the conical cylinder 26 with the peripheral wall 38. As a result, fine mist is generated. Since the fine mist is generated on the peripheral wall 38 provided above the slope, the fine mist can be generated on the slope through which air flows, and the fine mist can be efficiently put on the air.

(Summary)
As described above, according to the water fracturing negative ion generator 10 according to the present embodiment, the water supply tank 17 for supplying water to the water tank 16 is a sealed container having an opening 18 below, and the opening 18 is a predetermined container. Since it is provided at a position lower than the water level W, water can be discharged to the water tank 16 side until the negative pressure at the upper part of the water supply tank 17 becomes close to atmospheric pressure, and the water level of the water tank 16 can be kept constant. Can be generated stably.

  Further, around the sirocco fan 22, a spiral cylinder 31 having a winding wall portion 33 wound in the rotation direction of the sirocco fan 22 is provided to form a positive pressure chamber 32. For this reason, the wind generated by the sirocco fan 22 increases in flow velocity by passing between the winding wall portions 33. Further, below the positive pressure chamber 32, a spiral cylinder 37 having a spiral slope gradually lowering in the rotational direction of the sirocco fan 22 is provided to form a mist generating chamber 42. For this reason, the flow velocity of air can be increased here, too, and the generated fine mist can be efficiently put on the air.
