The constant water level chamber 10 in which is set is communicated via the water passage 11, and the water supply tank 9 is configured to keep the water storage chamber 8 at a constant water level by supplying the water supply by a drop method. . A float sensor 12 is provided in the constant water level chamber 10 and outputs a water level detection signal for detecting the presence of a water level when the water storage chamber 8 and the constant water level chamber 10 have water stored above a certain level. .

  Reference numeral 13 denotes a drive motor as a drive means for supporting the water storage chamber 8 below the water storage chamber 8, which is fixed to a substrate 15 which is covered with a cover body 14 and constitutes the bottom of the apparatus main body 1, and further covers the cover body. The outer peripheral wall 14 is formed with a bowl-shaped running water groove 16 projecting outward.

  Reference numeral 17 denotes a cylindrical rotating body that is supported by a drive shaft 18 that submerges the lower part of the water storage chamber 8 and rotates the blower 4 through the water storage chamber 8. The rotating body 17 has a hollow inverted conical shape. The diameter gradually expands upward, and by rotating the rotating body 17, the water stored in the water storage chamber 8 is pumped up by the centrifugal force of this rotation and is pushed up along the outer and inner walls of the rotating body 17. The stored water pushed up along the outer wall of the rotating body 17 is scattered to the surroundings, and the stored water pushed up along the inner wall of the rotating body 17 is scattered to the surroundings from a plurality of spray ports 19 formed at the upper end of the rotating body 17. It is something to be made.

  20 is a cylindrical porous body that is positioned on the outer periphery of the rotating body 17 at a predetermined interval and rotates together with the rotating body 17. The porous body 20 has a large number of slits, a metal mesh, punching metal, etc. The porous portion 21 is formed, the water in the water storage chamber 8 is pumped up by the centrifugal force generated by the rotation of the rotating body 17 and the air is scattered, and the porous portion 21 is allowed to pass through or hit and crushed. Water particles are refined to generate nanometer (nm) size mist, and negative ions are generated by the Leonard effect of water particle refinement. Furthermore, it collides with the inner wall of the blower cylinder 6 on the outer periphery of the porous body 20 and is refined, and the collision body is constituted by the porous body 20 and the blower cylinder 6.

  A heater 22 is wound around the outer periphery of the water storage chamber 8 and serves as a heating means for heating the water stored in the water storage chamber 8. When the air flow rate is set to “strong”, the water storage temperature in the water storage chamber 8 is set. When the air flow rate is set to be “low” around the temperature of 38 ° C., the water storage temperature in the water storage chamber 8 is heated and kept at the set temperature of about 34 ° C., and the blowing temperature is kept at about 30 ° C. The heater 22 is turned on / off and held at a predetermined temperature by the temperature detected by the temperature sensor 23 as a temperature detecting means comprising a thermistor that discharges from the bottom of the water 8 and detects the temperature of the water stored in the water storage chamber 8. A mode in which the heater 22 is forcibly turned off and the water stored in the water storage chamber 8 is not heated can be set.

  24 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 20, and an insertion hole 25 of the rotating body 17 is formed at the center. Since the water surface is partitioned by the support piece 26 extending from the outer periphery 25 to the outer periphery, the water flow to be rotated by the rotation of the rotating body 17 is prevented, and the water flow is easily generated by the action of the centrifugal force due to the rotation of the rotating body 17. The inner and outer circumferences can be raised. Further, the water flow blocking means 24 receives a relatively large water droplet that has not been refined by colliding with the upper air blowing cylinder 6 or the porous body 20, so that the water drop is generated directly by dropping on the water surface of the water storage chamber 8; It is possible to prevent the falling sound of bash, and for that purpose, it is gently descending from the outer periphery toward the insertion hole 25 in the center, and water droplets are reliably returned to the water storage chamber 8 in a natural manner. It is something that can be done.

  Reference numeral 27 denotes a flow passage that discharges nanomist and negative ions generated by the rotation of the rotating body 17 and the porous body 20 from the blower outlet 28 at the top of the processing chamber 7 by driving the blower 4. From the gap with the water flow blocking means 24, it is constituted by a flow path that rises between the processing chamber 7, the guide cylinder 5, and the blower cylinder 6 and goes to the outlet 28.

  A drain valve 29 is provided in the water passage 11 communicating with the water storage chamber 8 and is always pressed toward the valve closing side. When the water supply tank 9 is set (stored) in the constant water level chamber 10, a compression spring ( When the lot 30 which is constantly pushed up is pushed down by the not shown), the lower end of the lot 30 locks the locking metal 31 and the drain valve 29 is closed, and the water supply tank 9 is set. The drainage of the remaining water in the water storage chamber 8 is surely prevented. When the water supply tank 9 is removed, the lot 30 is pushed upward by the compression spring, the lock of the locking metal fitting 31 is released, and the drainage The valve 29 is in a state where it can be opened.

  32 is a drainage tray with an open top surface that receives the drainage of the remaining water in the water storage chamber 8 and is provided so as to be freely inserted into and removed from the mist generator main body 1. A handle portion 33 is formed on the front surface, and the volume of the water storage chamber is It is set to a size that can sufficiently accommodate 8 residual water. Further, the drain tray 32 is formed with a protruding wall 34 on the inner rear side, and when the drain lever 35 is lowered, the locking fitting 31 presses the drain valve 29 to open the valve, and at that time, the lower end of the drain lever 35 projects. It is located below and outside the wall 34, and prevents the drain tray 32 from being pulled out during drainage by engaging the projecting wall 34 and the drain lever 35. Then, the pressing of the locking metal fitting 31 is released, the drain valve 29 is closed, the drain tray 32 is easily pulled out, and the waste water stored therein can be discarded into the kitchen or the like.

  36 is an umbrella-shaped shielding plate provided in the middle of the drive shaft 18 between the water storage chamber 8 through which the drive shaft 18 penetrates and the cover body 14, and the water leaked from the water storage chamber 8 is transmitted through the drive shaft 18 portion and driven. Intrusion into the motor 13 is prevented.

  Reference numeral 37 denotes a water supply port cap of the water supply tank 9, and water is supplied from the water supply tank 9 to the constant water level chamber 10 by being pushed up by a fixed support (not shown) of an internal valve mechanism (not shown). is there. Also, 38 is a tank lid that opens and closes when the water supply tank 9 is taken in and out, 39 is a handle for attaching and detaching the lid body 2, and 40 is a wind direction plate that is provided in the air outlet 28 and changes the blowing direction of nanomist and negative ions. It is.

  41 is a control means for receiving the detection signals of the temperature sensor 23 and the float sensor 12 and controlling the operation of the heater 22 and the drive motor 13, and this control means 41 is an operation provided on the front of the mist generator main body 1. The operation start signal of the operation switch 43 provided in the unit 42 is received, the blower 4, the drive motor 13, and the heater 22 are controlled to start the mist operation, and by receiving the operation stop signal, The heater 22 is energized to stop the operation after performing a sterilization operation in which the stored water is heated to 70 ° C., which is higher than that in the normal operation, and held for 5 minutes.

  As the other operation switches 44 in the operation unit 42, an air volume switch 45 for switching the air volume of the blower 4 between strength and a priority temperature mist for generating mist by storing water heated by energizing the heater 22, and a mist without heating. A warm mist switch 46 that selects a cold mist that requires a selection operation to generate a cut-off timer switch 47 that can select a 1-hour or 2-hour cut-off timer is provided.

  48 is a child lock switch provided in the operation section 42, and is pressed during operation, so that the control means 41 does not accept the operation of the other operation switches 44 and only the operation stop signal of the operation switch 43 is received. However, at this time, the sterilization operation that is always performed at the time of the operation stop is not performed, but the operation is stopped immediately. If the child has been sterilized at high temperature for a minute, there is a risk of burns if the child knocks down the mist generator main body 1. Therefore, in the child lock state, the sterilization operation is not performed and the danger is prevented beforehand. It is a thing.

Next, the operation of the mist generator according to the embodiment shown in the flowchart of FIG. 4 will be described.
First, when the operation switch 43 is turned on (step 49), a warm mist operation is performed in which the heater 22 is energized and the stored water stored in the water storage chamber 8 is heated to a preset temperature, for example, 30 ° C. When the water storage temperature in the water storage chamber 8 detected by the temperature sensor 23 reaches 30 ° C., the heater 22 is turned off and controlled so that the water storage temperature is always kept at 30 ° C. (step 50). 13 is started, and a warm mist operation for generating nano mist and negative ions is executed (step 51).

  In the temperature mist operation, the control means 41 turns on / off the heater 22 based on the water storage temperature in the water storage chamber 8 detected by the temperature sensor 23 to store water at a constant water level in the water storage chamber 8. The control means 41 controls the drive motor 13 so as to have a set rotation speed, and performs a mist operation that generates nano mist and negative ions and supplies them into the room.

  The blower 4 and the rotating body 17 that are coaxially fixed to the drive shaft 18 are driven to rotate by the drive motor 13, and the rotation of the blower 4 guides the indoor air sucked from the suction port 3 to the guide tube 5. After suction, it is discharged below the processing chamber 7.

  On the other hand, in the rotation of the rotating body 17, the water stored in the water storage chamber 8 heated to a predetermined temperature is pumped up by the rotation of the lower end of the rotating body 17, and is pushed up by the centrifugal force along the outer and inner walls of the rotating body 17. In addition, the water stored in the outer wall of the rotating body 17 is scattered outwardly, and the water stored in the inner wall of the rotating body 17 is pushed up and formed in the upper end of the rotating body 17. The water stored in the outer periphery of the rotating body 17 is smashed by colliding with the porous portion 21 of the porous body 20 which is located on the outer periphery of the rotating body 17 at a predetermined interval and rotates together with the rotating body 17. Or the thing which passed the porous part 21 collides with the inner wall of the outer periphery blowing cylinder 6, and is refined | miniaturized.

  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 17 tries to form a water flow rotating in the same direction as the rotating body 17, but the support piece 26 of the water flow blocking means 24 is on the water surface. Since it sinks and becomes a resistance and the formation of a rotating water flow is prevented, the centrifugal force acts sufficiently and the stored water is pushed up on the peripheral wall of the rotating body 17 and is crushed well as described above. .

  And while producing | generating nanomist by crushing and refinement | miniaturization of this heated warm water, negative ions are generated by the Leonard effect, and the generated nanomist and negative ions are once flown by the air flow toward the lower side of the processing chamber 7 of the blower 4 described above. After hitting against the blocking means 24 and dropping the large and heavy mist onto the water flow blocking means 24 and removing it, only fine nano mist and negative ions are set by the wind direction plate 40 from the upper outlet 28 via the flow passage 27. The air is discharged in the blowing direction and supplied to the room, and the room is humidified or cleaned.

  Further, the water flow blocking means 24 receives a drop of relatively large water droplets that have not been refined by colliding with the upper air blowing cylinder 6 or the porous body 20, so that the water droplets directly fall on the water storage surface of the water storage chamber 8. The generated bash and bash sound can be blocked, and the water flow blocking means 24 is gently descending from the outer periphery toward the insertion hole 25 at the center, so that the dropped water droplets Is surely returned to the water storage chamber 8 from the insertion hole 25, and the sound when returned is quiet.

  Furthermore, since the released nanomist is generated from heated storage water, it is possible to obtain a release of warm and cold mist and negative ions, which can be used regardless of the winter season. The supplied nanomist is about 30 ° C. Since it is an intermediate temperature that is neither high nor low, it is safe and can be used safely without the risk of burns due to precipitation or falling.

  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, it improves circulation and spreads blood to the peripheral blood vessels. 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 every corner of the air and bacteria It suppresses and smells and decomposes even now, and it has deodorizing effect, dust removing effect, sterilizing effect, and of course a humidifying effect.This humidification is smooth and moist air with no stickiness, and it penetrates through pores. The effect of keeping the skin and hair moisturized, and the release of a large amount of negative ions and nanomist capable of obtaining these effects also increases these effects.

  Further, in order to release nano mist and negative ions into the room, the room air sucked from the suction port 3 by driving the blower 4 crosses the stored water scattered in the processing chamber 7, so that the air is filtered in the air. Since the dust and germs are finally mixed in the water storage of the water storage chamber 8, the indoor air cleaning is performed strongly and satisfactorily.

  Furthermore, when using the mist generator main body 1 as a facial device, the nano mist released from the air outlet 28 enters the facial skin from the countless small pores of the face by bringing the face close to the air outlet 28. Improves skin's moisture retention and removes impurities in the skin. Negative ions remove waste from the surface of the skin and make it possible to regain beautiful and shiny skin. It can be repeated every day while having fun.

  Next, the control means 41 determines whether or not the operation switch 43 that has been stopped is detected (step 52). If YES, the control means 41 further determines whether or not the child lock switch 48 is operated (step 53). If not operated, NO stops the drive motor 13 to stop the rotation of the blower 4 and the rotating body 17 fixed coaxially to the drive shaft 18, and the heater 22 is energized to set the water storage temperature to 70 ° C. The sterilization operation for sterilizing germs in the stored water by high temperature heating is performed (step 54), and the time measuring function in the control means 41 counts the time for this sterilization operation for 5 minutes. By counting the time (step 55), the entire operation including the sterilization operation is terminated with YES (step 56).

  In the child lock state in which the child lock switch 48 is pressed and the control means 41 does not accept the operation of the air flow switch 45, the temperature mist switch 46, and the turn-off timer switch 47, which are the other operation switches 44, in step 53. It becomes YES by judgment and it progresses to complete | finishing all the operations of step 56, without performing disinfection operation for 5 minutes.

  As a result, child locks caused by anxiety about children's mischief, but if high temperature sterilization operation was performed for 5 minutes after the operation stopped, there is a risk of burns if a child knocks down the mist generator body 1 by any chance. In the child lock state, the sterilization operation is not performed and the operation is stopped to prevent danger.
