The control means 41 includes a heater control means 43 for controlling the output of the heater 22, a motor control means 44 for controlling the output of the drive motor 13, and a mist operation described later. Furthermore, when the output of the heater 22 is turned off by the heater control means 43, the detected temperature of the water stored in the water storage chamber 8 detected by the temperature sensor 23 is a predetermined temperature from the set temperature T of the water stored in the water storage chamber 8. Count means 45 that counts the number of times the temperature has been raised across a high preset overheat temperature, and the float sensor detects no water level during mist operation And, when the count of the counting means 45 reaches a preset number of times during the mist operation, the error stopping means 46 stops the driving of the heater 22 and the drive motor 13 and stops the mist operation, Timer means 47 for measuring time in the sleep mode is provided.

Next, operation | movement of the mist generator of one Embodiment shown in FIG. 1 is demonstrated.
First, when the operation switch of the operation unit 42 is turned on, the heating heater 22 is turned on and a sterilization mode for heating to a preset temperature sufficient to sterilize the stored water stored in the water storage chamber 8, for example, 70 ° C. When the water storage temperature in the water storage chamber 8 detected by the temperature sensor 23 reaches 70 ° C., the heater 22 is turned off to end the sterilization mode, and then the drive motor 13 is started to drive. The normal mode for generating nanomist and negative ions is executed.

  In the normal mode, the heater control means 43 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 set the water stored at a constant water level in the water storage chamber 8 to the set temperature. The motor control means 44 controls the drive motor 13 so as to have a set rotational 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 the heated water storage, it is possible to use the nanomist and negative ions that are not chilly and warm, and can be used regardless of the winter season. The supplied nanomist is about 30 ° C. This is an intermediate temperature that is neither high nor low, so 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, with negative ions, there are 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, 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 17 and the porous body 20, 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. 9 is automatically replenished, and if the water storage temperature is lowered by this water replenishment, the heater 22 is turned on to control the water storage temperature to always become a predetermined temperature, which is always comfortable to the skin. The temperature nano mist can be continuously supplied.

  Further, when the water supply in the water supply tank 9 becomes empty, the tank lid 38 is opened, the water supply tank 9 is taken out from the mist generating device main body 1, tap water is supplied from the kitchen faucet and returned to the original state. It can be used again in the same way, and is very convenient to use.

  In addition, in order to release nano mist and negative ions into the room, the indoor air sucked from the suction port 3 by driving the blower 4 intersects with the water stored in the processing chamber 7 so that dust and germs in the air are collected. Eventually, the water is mixed into the water storage in the water storage chamber 8, so that the indoor air is strongly and satisfactorily cleaned.

  Further, when the mist generating device body 1 is used 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. Enhances the 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 clean, shiny skin, and relax mentally. It can be repeated every day while having fun.

Next, the mist operation in the sleep mode will be described using the flowchart shown in FIG.
First, when the sleep mode switch of the operation unit 42 is turned on (S1), the control unit 41 operates the timer unit 47 to start timing. (S2)
Then, the control means 41 starts the mist operation by setting the air flow rate to “weak”. (S3)

When the time measured by the timer means 47 reaches a predetermined time (S4), the control means 41 is set to the set temperature T of the water storage temperature in the water storage chamber 8 while the air flow rate is “weak” when the air flow rate is “weak”. The predetermined temperature t is lower than the set temperature 34 ° C., in this embodiment, the set temperature T is set to 30 ° C. (S5), and in this embodiment, the predetermined time is 30 minutes. (S5)
As a result, the temperature of the air containing warm nanomist and negative ions blown out from the outlet 28 is reduced from 30 ° C. before the set temperature change to 26 ° C.

  Then, the mist operation is continued in this state (S6), and when the float sensor 12 detects that the water stored in the water storage chamber 8 has become below a certain water level (S7), the control means 41 determines that the water has run out and is in a sleep mode. Is released (S8), the heater 13 is turned off, and the drive motor 22 is stopped to stop the mist operation. (S9)

  As described above, since the mist operation is performed while the temperature in the water storage chamber is maintained at the set temperature T until a predetermined time has elapsed after the sleep mode is set, the warm nano mist of the normal set temperature T and the negative temperature until the user falls asleep at bedtime. The air containing the ions is released into the room, so that the user does not feel a cold wind and can sleep asleep smoothly. Further, after a predetermined time has elapsed since the sleep mode was set, the user sets the set temperature T in the water storage room. Since the mist operation is performed by changing the temperature to a temperature lower by the predetermined temperature t, the operation time can be extended as compared with the mist operation performed by keeping the temperature in the water storage chamber at the normal set temperature T.

In this embodiment, the mist operation is performed while the temperature in the water storage chamber is maintained at the set temperature T until the elapse of 30 minutes after the sleep mode is set, and the sleep mode is set for a predetermined time after the sleep mode is set. After the lapse of 30 minutes, the mist operation is performed by changing the set temperature T in the water storage chamber to a temperature lower by a predetermined temperature t, in this embodiment, a set temperature lower by 4 ° C. The temperature T may be divided into any number of stages and changed to a temperature lower by a predetermined temperature t.
That is, for example, after 15 minutes, which is half of the predetermined time 30 minutes after the sleep mode is set, the set temperature T in the water storage chamber is changed to a set temperature that is 2 ° C. lower than the predetermined temperature t, and then further The set temperature T in the water storage chamber may be further changed to a set temperature lower by 2 ° C., which is half of the predetermined temperature t, after 15 minutes, which is half of the predetermined time of 30 minutes, have elapsed.

  In this way, by changing the set temperature T in the water storage chamber into a number of stages and changing it to a temperature lower than the predetermined temperature t, the temperature drop of the air blown out from the outlet 28 can be reduced and the feeling of cold air can be made less felt. Is.

  In addition, when a mist operation is performed by changing the set temperature T in the water storage chamber to a temperature lower by a predetermined temperature t after a predetermined time has elapsed since the sleep mode was set, the air flow rate may be further reduced. Thus, the duration of the mist operation can be made longer.
