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 generating device main body 1. 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.

  Reference numeral 41 denotes an operation switch (not shown), an operation changeover switch (not shown) for setting one of a warm mist operation, a cold mist operation, and a sterilization operation, an air blow switch (not shown) for setting an air flow rate, and the like. The control means 41 is a control means for controlling the operation of the heater 22 and the drive motor 13 in response to input signals from the operation unit 42 provided and detection signals from the temperature sensor 23 and the float sensor 12.

When the absence is detected or when an abnormality such as an error stop occurs, the notification means 48 notifies the abnormality by voice or buzzer.

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 control means 41 first confirms the open / close state of the air outlet 28, and when the air outlet 28 is opened, the heater 22 is turned on by the operation switch. Or a sterilization operation in which the heater 22 is turned on and heated to a preset temperature sufficient to sterilize the water stored in the water storage chamber 8, for example, 70 ° C. It is determined which of the cold mist operations that generate cold mist while the heater 22 is OFF is set. If the sterilization operation is set, the heater 22 is turned ON and the water storage chamber 8 is turned on. A sterilization operation for heating to a preset temperature sufficient to sterilize the stored water stored therein, for example, 70 ° C., is performed, and the stored water temperature in the water storage chamber 8 detected by the temperature sensor 23 is 70. ℃ Reached, is for notifying that the heater 22 has been completed filtering operation OFF, filtering operation automatically OFF the operation switch has been completed.

  If the cold mist operation is set after confirming that the air outlet 28 is open, the drive motor 13 is started while the heater 22 is turned off, and nanomist and negative ions are removed. The generated cold mist operation is executed.

  Further, after confirming that the air outlet 28 is opened, if the warm mist operation is set, the heater control means 43 performs heating based on the water storage temperature in the water storage chamber 8 detected by the temperature sensor 23. The heater 22 is turned on / off to control the water storage at a constant water level in the water storage chamber 8 to be held at the set temperature T, and the motor control means 44 controls the drive motor 13 to have a set rotational speed. A warm mist operation is performed in which nano mist and negative ions are generated and supplied into the room.

  In the warm mist operation, the blower 4 and the rotating body 17 that are coaxially fixed to the drive shaft 18 are driven to rotate by driving the drive motor 13, and in the rotation of the blower 4, the indoor air sucked from the suction port 3 is guided to the guide tube. After being guided to 5 and sucked, 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. If the water storage temperature is lowered by this water replenishment, the heater 22 is turned on in the warm mist operation to control the water storage temperature at a predetermined temperature. It can continuously supply nano mist at a temperature comfortable for the skin.

  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 operation for confirming the open / closed state of the air outlet 28 at the start of operation will be described using the flowchart shown in FIG.
First, when the operation switch of the operation unit 42 is turned on (S1), the control means 41 determines whether the air outlet 28 is opened or closed (S2). It is determined which one of the sterilization operation for heating the stored water stored in 8 to a high temperature or the cold mist operation for generating cold mist is set. (S3)

Therefore, when the warm mist operation or the cold mist operation is set, the control means 41 determines whether the lid of the air outlet 28 is opened or closed based on the output value of the heater 22. (S4)
First, the control means 41 starts a normal warm mist operation (S5), and starts measuring time by the timer means 47. (S6)
When a predetermined time, 10 minutes in the present embodiment, has elapsed since the timer 47 started measuring time (S7), the output value of the heater 22 at that time is compared with a predetermined value. (S8)

  This is because during the warm mist operation, the outlet temperature from the outlet 28 is a predetermined temperature, and in this embodiment, the heater 22 heats the water stored in the water storage chamber 8 in order to maintain the outlet temperature at about 30 ° C. Although the water storage temperature in the water storage chamber 8 is heated and kept at a set temperature, if the lid of the air outlet 28 is opened, the warmed water in the water storage chamber 8 is pumped up by the rotation of the lower end of the rotary body 17, and the rotary body 17 is crushed or miniaturized by colliding with the porous portion 21 of the porous body 20 rotating together with 17, and discharged from the upper outlet 28 through the flow passage 27 in the blowing direction set by the wind direction plate 40. As a result, the amount of water stored in the water storage chamber 8 is lowered, so that water is supplied from the water supply tank 9 and the water storage temperature in the water storage chamber 8 is lowered. Therefore, the heater 22 continues to be heated at a predetermined output.

  However, when the cover of the outlet 28 is opened, the water stored in the warmed water storage chamber 8 is not discharged from the outlet 28, so that the temperature in the water storage chamber 8 is increased and the water supply tank 9 to the water storage chamber 8 is increased. Therefore, the water storage temperature in the water storage chamber 8 does not decrease so much, and the output of the heater 22 that heats and maintains the water storage temperature in the water storage chamber 8 at a set temperature is smaller than a predetermined output. .

  In this embodiment, when the lid of the outlet 28 is opened in the warm mist operation in advance, the output of the heater 22 is 30% of the rated value, whereas the lid of the outlet 28 is closed in the warm mist operation. It has been confirmed that the output of the heater 22 is 10% of the rating.

  Thereby, the predetermined value in (S8) is set to 20% of the rating, and when the output of the heater 22 is less than 20% of the rating in (S8), the control means 41 has the lid of the outlet 28 opened. (S9), the setting by the mode change switch is confirmed again (S10), and if the setting is the warm mist operation, the warm mist operation is continued as it is (S11), and the setting is the cold mist operation in (S10). In this case, the heater 22 is turned off to end the warm mist operation once (S12), and the cold mist operation is started while the heater 22 is turned off. (S13)

  Although the cold mist operation is started in (S13), since the stored water temperature in the water storage chamber 8 is heated and kept at the set temperature, warm nanomist is discharged from the outlet 28 at first, but the cold mist operation is continued. Thus, water is supplied from the water supply tank 9 into the water storage chamber 8, the water storage temperature in the water storage chamber 8 is lowered, and cold nanomist is discharged from the warm nanomist, so that the cold mist operation is performed.

  When the output of the heater 22 is 20% or more of the rated value in (S8), the control means 41 determines that the lid of the air outlet 28 is closed (S14) and ends the warm mist operation (S15). ), The operation switch is automatically turned OFF (S16), and the notification means 48 notifies the opening of the outlet 28 to be opened. (S17)

Further, when the sterilization operation is set by the mode change switch in (S3), the control means 41 determines whether the cover of the outlet 28 is opened or closed according to the water storage temperature in the water storage chamber 8. (S18)
First, the control means 41 starts a normal sterilization operation (S19). When the water storage temperature in the water storage chamber 8 becomes equal to or higher than a predetermined temperature (S20), the power supply to the heater 22 is turned off (S21). Time measurement by the timer means 47 is started. (S22)

  Then, when 10 minutes have elapsed in the present embodiment after the timer means 47 starts measuring time (S23), the water storage temperature in the water storage chamber 8 at that time is compared with a predetermined temperature. (S24)

  During the sterilization operation, this is set to a preset temperature sufficient to sterilize the water stored in the water storage chamber 8 by heating the heater 22, which is 70 ° C. in this embodiment. When the temperature reaches a certain temperature, the heater 22 is turned off and the sterilization operation ends. However, when the air outlet 28 is opened, the heat stored in the water storage chamber 8 is released from the air outlet 28. When the air outlet 28 is closed, the heat of the water stored in the water storage chamber 8 cannot escape, and the water storage chamber 8 when the air outlet 28 is opened after a predetermined time has elapsed after the heater 22 is turned off. The water storage temperature inside is lower than that when the air outlet 28 is closed, and in this embodiment, the water storage in the water storage chamber 8 reaches a preset temperature of 70 ° C. and the heater 22 is heated. When a predetermined time of 10 minutes has elapsed after turning OFF Water temperature in the water storage chamber 8, 25 ° C. If the outlet 28 is open, it has been confirmed that when the outlet 28 is closed is 35 ° C..

  Accordingly, the predetermined temperature in (S24) is set to 30 ° C., which is an intermediate temperature between the temperature when the air outlet 28 is opened and the temperature when the air outlet 28 is closed in this embodiment. When the water storage temperature in the water storage chamber 8 at (S24) is less than 30 ° C., the control means 41 determines that the lid of the air outlet 28 is opened (S25) and ends the sterilization operation. The operation switch is automatically turned off (S27), and the notification means 48 notifies the end of the sterilization operation. (S28)

  When the water storage temperature in the water storage chamber 8 is 30 ° C. or higher in (S24), the control means 41 determines that the lid of the air outlet 28 is closed (S29), and ends the sterilization operation ( In S30) and (S16), the operation switch is automatically turned OFF, and the notification means 48 notifies that the lid of the outlet 28 is opened. (S17)

  As described above, when the operation setting is the warm mist operation or the cold mist operation, whether the air outlet 28 is opened or closed is determined based on the output of the heater 22 in the warm mist operating state. If it is determined that the cover for the air outlet 28 is open, if the warm mist operation is set, the warm mist operation is continued and the cold mist operation is set. Although warm mist is released for a while, cold mist is released after a while and cold mist operation is performed. If it is determined that the lid of the outlet 28 is closed, the outlet 28 is informed to open. Even if the person does not care about opening and closing of the air outlet 28, the mist generator checks the opening and closing of the air outlet 28, so that the usability can be improved.

  In addition, when the operation setting is the sterilization operation, the opening / closing determination of the outlet 28 is determined by the water storage temperature in the water storage chamber 8 after a predetermined time since the heater 22 is turned off in the sterilization operation state. If it is determined that there is no need to provide detection means for detecting the opening / closing of the air outlet 28 and that the lid of the air outlet 28 is open, a notification that the sterilization operation has ended is given, and the air outlet 28 lid is closed. If it is determined that the air outlet 28 is opened, the user is informed that the air outlet 28 is opened. Because it does, it can improve usability.
