Abstract

PROBLEM TO BE SOLVED: To provide a mist generator capable of preventing freezing of water stored in a water storage room and ensuring driving a drive motor.SOLUTION: If an operation switch 42 is operated, a temperature sensor 23 detects a temperature of water stored in a water storage chamber 8. If the detected temperature is lower than 0°C, then it is determined that the water in the water storage room 8 is frozen, driving of a drive motor 13 is stopped, and a heating heater 22 is turned on to heat the water in the water storage room 8. If the temperature detected by the temperature sensor 23 is equal to or higher than 0°C, then it is determined that the water in the water storage room 8 is defrosted, the heating heater 22 is turned off, and the driving of the drive motor 13 is started. By doing so, even if there is a possibility that a surrounding temperature of a device main body 1 is low and that the water in the water storage room 8 is frozen, the driving of the drive motor 13 is started after the water surrounding a drive shaft 18 is defrosted.

When the motor control means 48 for controlling the output and the float sensor 12 detects no water level during the mist operation, the heater 22 and the drive motor 13 are stopped and the water supply lamp 49 installed in the operation unit 41 is turned on. Error stopping means 50 that stops the mist operation and notifies an error.

  Since the operation state before turning off the operation switch 42 is stored in the storage circuit of the control unit 46, for example, if the air flow immediately before turning off the operation switch 42 is “strong”, then the operation switch When the air flow 42 is turned on, the air flow is started at “strong”, and if the warm mist operation is performed immediately before the operation switch 42 is turned off, the heater 22 is driven the next time the operation switch 42 is turned on. Start warm mist operation.

Next, the control at the start of the mist operation of one embodiment will be described based on the flowchart of FIG.
First, the control unit 46 determines whether or not the operation switch 42 has been operated (step S101). If the operation switch 42 has been operated, the inside of the water storage chamber 8 detected by the temperature sensor 23 installed in the water storage chamber 8 is determined. The temperature T of the stored water is confirmed (step S102).

  After confirming the temperature T detected by the temperature sensor 23 in step S102, the control unit 46 determines whether the detected temperature T is less than 0 ° C. (step S103), and if the detected temperature T is less than 0 ° C. Assuming that the water in the water storage chamber 8 is frozen, the motor control means 48 stops driving the drive motor 13, the heater control means 47 turns on the heater 22, and the air flow rate of the mist operation character is “ By setting the output to “strong”, the inside of the water storage chamber 8 is heated (step S104).

  When the heater 22 is turned on in step S104, the controller 46 confirms the temperature T of the stored water in the water storage chamber 8 detected by the temperature sensor 23, and determines whether the detected temperature T is equal to or higher than 0 ° C., which is a predetermined value. (Step S105), if the detected temperature T is 0 ° C. or higher, the water in the water storage chamber 8 is defrosted and the motor control unit 48 starts driving the drive motor 13, and the previous time It is determined whether the operation mode when the operation switch 42 is OFF is a normal mist operation or a warm mist operation with the heater 22 turned on. If the operation mode is a normal mist operation, the heater 22 is turned off. Then, the output of the heater 22 is changed based on the setting of the blowing amount at the previous stop of the warm mist operation, and the mist operation is continued (step S106).

  If it is determined in step S103 that the temperature T detected by the temperature sensor 23 is equal to or higher than 0 ° C., the control unit 46 determines that the water in the water storage chamber 8 is not frozen, and drives the drive motor 13 in step S106. Is started, the heater 22 is turned on / off based on the operation mode at the time of the previous operation stop, and the mist operation is started.

  In step S104, the heater 22 is set to output when the air flow rate during the mist operation is “strong”. However, the output of the heater may be changed depending on the temperature detected by the temperature sensor 23. If the temperature T detected by the temperature sensor 23 after the switch 42 is operated is −5 ° C.> T, the output is the output when the air flow rate is “strong”, and if 0 ° C> T ≧ −5 ° C., the air flow rate is “weak”. By turning on the heater 22 with the output of the hour, the temperature in the water storage chamber 8 can be quickly warmed and the power consumption in the heater 22 can be reduced.

  As described above, the temperature in the water storage chamber 8 is detected by the temperature sensor 23 at the start of operation, and if the detected temperature is 0 ° C. or less, the heater 22 is turned on, and the temperature detected by the temperature sensor 23 is Since the water stored in the water storage chamber 8 is heated until the temperature becomes 0 ° C. or higher, the temperature around the instrument body 1 is low, the water stored in the water storage chamber 8 is frozen, and the drive shaft 18 connected to the drive motor 13 cannot operate. Therefore, the rotating body 17 can be reliably rotated to pump up the water stored in the water storage chamber 8 and be crushed so that nanomist and negative ions can be supplied into the chamber.

  Note that the numerical values and configurations used in the description of the present embodiment can be changed without departing from the gist of the present invention. For example, when the temperature in the water storage chamber 8 becomes less than 3 ° C., the water storage chamber 8 The heater 22 is turned on because there is a risk of water freezing, and when the temperature detected by the temperature sensor 23 is 3 ° C. or higher, the heater 22 is turned off and the drive motor 13 is started to drive. May be changed as appropriate.
