  Reference numeral 12 denotes a drive motor that supports the water storage chamber 8 below the water storage chamber 8, and is fixed to a substrate 14 that is covered with the cover body 13 and forms the bottom of the humidifier body 1. The wall is formed with a bowl-shaped running water groove 15 projecting outward.

  Reference numeral 16 denotes a cylindrical rotating body that is supported by a drive shaft 17 that submerges the lower part of the water storage chamber 8 and rotates the blower 4 through the water storage chamber 8. The diameter of the rotating body 16 gradually increases toward the surface, and the rotating body 16 rotates to push up the water by the centrifugal force of the rotation, and to scatter the water to the outer periphery from the plurality of scattering ports 18 formed at the upper end.

  19 is a cylindrical porous body that is positioned on the outer periphery of the rotating body 16 at a predetermined interval and rotates together with the rotating body 16. Water and air are scattered by centrifugal force generated by the rotation, and the entire peripheral wall is formed. By making the porous portion 20 made of a large number of slits, wire mesh, punching metal, etc. formed or passing and collapsing, the water particles are refined to produce nano mist, and the water particles are refined. The negative ions are generated by the Leonard effect, and the water particles that have passed through the porous portion 20 further collide with the inner wall of the blower cylinder 6 on the outer periphery to be refined.

  Reference numeral 21 denotes a heater that is submerged in the water stored in the water storage chamber 8 so that the water does not feel cold. Here, the heater 8 heats and holds the water to around 40 ° C. In order to heat the entire water storage to the predetermined temperature in a short time, the water storage chamber 8 When the water storage temperature reaches 40 ° C., the heater 21 is turned off via the control circuit or the energized wattage is reduced by the water temperature sensor 22 attached to the outer wall of the water storage chamber 8. However, it is turned off for the first time when the temperature rises, and then turned on again when the water storage temperature drops to 39 ° C, so that the water storage temperature is kept at 40 ° C.

  23 is a dish-shaped water flow blocking means which covers the upper surface of the water storage chamber 8 so as to face the lower ends of the blower cylinder 6 and the porous body 19. An insertion hole 24 of the rotating body 16 is formed at the center, and this insertion hole The water surface is divided into a plurality of portions by the tip portions 25 a of the plurality of support pieces 25 extending radially from the outer periphery to the outer periphery, thereby preventing a water flow to rotate due to the rotation of the rotating body 16, and centrifugal separation due to the rotation of the rotating body 16. The water flow can easily rise on the inner and outer periphery of the rotating body 16 by force, and the water flow blocking means 23 is a relatively large droplet of water that has not been refined by colliding with the upper blowing cylinder 6 or the porous body 19. By receiving this, it is possible to prevent the falling sound called basher or bash that is generated when this water drop directly falls on the water surface of the water storage chamber 8, and for that purpose, the outer perimeter from the outer periphery to the insertion hole 24 in the center part. Gently descending toward And it is, those that can be returned to reliably reservoir chamber 8 drops of water.

  28 is a drainage tray with an open top surface that receives drainage from a drainage pipe 29 that communicates with the bottom of the water storage chamber 8, and is provided in the humidifier body 1 so that it can be freely inserted and removed. The remaining water is drained, and in the water flow groove 15 of the cover body 13 facing the upper opening of the water drain tray 28, the water flow groove is caused by water leakage from the drive shaft 17 portion that penetrates the water storage chamber 8. An outflow port 31 is provided for guiding the leaked water collected at 15 into the drain tray 28.

  32 is an umbrella-shaped shielding plate provided in the middle of the drive shaft 17 between the water storage chamber 8 through which the drive shaft 17 penetrates and the cover body 13. Water leaking from the water storage chamber 8 is transmitted to the drive shaft 17 portion. In addition to preventing the drive motor 12 from entering the drive motor 12, the leaked water is guided to the water flow groove 15.

Reference numeral 33 denotes a water supply cap of the water supply tank 9, which is configured to form a drop-type constant water level chamber 10 by pushing up an internal valve mechanism (not shown) by a fixed support portion 34.
Reference numeral 35 denotes a tank lid for taking in and out the water supply tank 9, and 36 denotes a handle for attaching and detaching the lid 2.

Next, the operation of the humidifier showing this embodiment will be described.
When the operation switch (not shown) is turned on, the heater 21 is turned on to directly heat the water stored at a constant water level in the water storage chamber 8, and the water stored in the water storage chamber 8 has a predetermined temperature of 40 here. The temperature sensor 22 detects that the temperature has reached 0 ° C., turns off the energization of the heater 21 via the control circuit, and starts driving the drive motor 12.

  When the drive motor 12 starts driving, the blower 4 and the rotating body 16 that are coaxially fixed to the drive shaft 17 are rotated, and the rotation of the blower 4 sucks indoor air sucked from the suction port 3 using the guide cylinder 5 as a guide. After that, it is discharged below the processing chamber 7.

  On the other hand, in the rotation of the rotating body 16, the water stored in the water storage chamber 8 heated to a predetermined temperature rises by being pushed up along the outer and inner walls of the rotating body 16 by the centrifugal force generated by the rotation of the lower end of the rotating body 16. The water stored in the outer periphery of the plurality of spray holes 18 is scattered to the outer periphery, and the water stored in the outer periphery is located at a predetermined interval on the upper outer periphery of the rotator 16 and rotates with the rotator 16. What collides with the porous part 20 of the body 19 and crushed or passes through the porous part 20 collides with the inner wall of the blower cylinder 6 on the outer periphery to be refined.

  At this time, the water stored in the water storage chamber 8 which is circular and has no resistance due to the rotation of the rotating body 16 tries to form a water flow rotating in the same direction as the rotating body 16, but the radial support piece 25 of the water flow blocking means 23. Since each tip portion 25a is immersed in the water surface to become a resistance and the formation of a rotating water flow is prevented, the centrifugal force acts sufficiently and the water is pushed up on the peripheral wall of the rotating body 16 as described above. Are crushed well.

  And by crushing and refinement | miniaturization of this heated storage water, while producing | generating a nano mist, a negative ion is generated by the Leonard effect, and this generated nano mist and a negative ion are blown toward the process chamber 7 lower side of the above-mentioned blower 4. After hitting the water flow blocking means 23 and dropping a large and heavy mist onto the water flow blocking means 23, only fine nano mist and negative ions are discharged from the upper outlet 27 through the flow passage 26. The room is humidified.

  Further, the water flow blocking means 23 receives a drop of a relatively large water droplet that has not been refined by colliding with the upper blowing cylinder 6 or the porous body 19, so that the water droplet directly falls on the water surface of the water storage chamber 8. The generated bash and bash can be prevented from falling sound, and the water flow blocking means 23 is gently inclined downward from the outer periphery toward the insertion hole 24 at the center, so that it has dropped. The water droplet is surely returned to the water storage chamber 8 from the insertion hole 24, and the sound when returning is quiet.

  Furthermore, since the released nanomist was originally produced from heated water storage, it was possible to obtain a warm and non-chilled nanomist and negative ion release, which can be directly touched by the skin and used regardless of the winter season. In addition, the supplied nano mist is a good intermediate temperature that is neither high temperature nor low temperature around 40 ° C, so there is no risk of burns caused by precipitation of calcite or tipping over, and it can be used safely and with peace of mind. .

  Negative ions aspirated from the lungs enter the blood, and their reduction action prevents blood oxidation and makes the blood smooth. At the same time, circulation is improved and blood is distributed to the peripheral blood vessels, causing pain and discipline. It is thought that can be eased.

  In addition, negative ions have fatigue recovery effect, mental stability effect, blood purification effect, resistance enhancement effect, autonomic nerve adjustment effect, etc., and nano mist spreads to every corner of the air and suppresses dirty air and bacteria However, it still decomposes and has a deodorizing effect, dust removing effect, disinfecting effect, and of course a humidifying effect. This humidification is smooth and moist air with no stickiness, and it penetrates through the pores. It has the effect of keeping the hair moisturized, and the release of a large amount of negative ions and nanomist capable of obtaining these effects increases these effects.

  Next, when the heated water stored in the water storage chamber 8 is released and reduced as nano mist one after another by the rotating body 16 and the porous body 19, the water level in the water storage chamber 8 decreases, and the water corresponding to the decreased water level is supplied to the water supply tank. When the water storage temperature is lowered by this water replenishment, the heater 21 is turned on and the water storage temperature is always kept at a predetermined temperature. Nanomist can be supplied continuously.

  Furthermore, when the water supply in the water supply tank 9 becomes empty, the tank lid 35 is opened, the water supply tank 9 is taken out from the humidifier main body 1, replenished with tap water from the kitchen faucet, and returned to its original state. It can be used in the same way and is very convenient.

  Further, when the penetration portion of the drive shaft 17 at the bottom of the water storage chamber 8 leaks water, the leaking water that tries to enter the drive motor 12 through the drive shaft 17 is blocked by the shielding plate 32, and the surface of the cover body 13 is left as it is. Or the flow from the beginning on the surface of the cover body 13 and collected in the running water groove 15, and the collected leaked water sequentially flows from the outlet 31 to the lower drainage tray 28 and is stored in the drainage tray 28. Even if water leaks from the drive shaft 17 that is most likely to cause water leakage, there is no worry of soiling the floor surface with leaked water, and it can always be used with confidence.

  Furthermore, the user detects a water leak by stopping the humidification operation due to a drop in the water level in the water storage chamber 8 or remaining water in the drain tray 28, and requests repair or the like from the dealer.
