Time counting means 53 that counts the time elapsed since the drain valve 46 was opened is provided.

Next, the operation of each part by the solenoid 20 in the energized ON / OFF state will be described in detail.
First, when the energization to the solenoid 20 is in an OFF state, the movable iron core 21 does not operate as shown in FIG. 5A, and the movable protrusion 22 is also stopped at a predetermined position. Therefore, the water supply valve 14 provided in the water supply lid 13 of the water supply tank 12 is lowered by being urged by its own weight and the elasticity of the water supply spring 18, and the valve portion 17 of the water supply valve 14 is in close contact with the valve seat 16 to close. Therefore, the water in the water supply tank 12 can be prevented from flowing out from the opening 15 and the water supply to the inner tray 9 can be prevented.

  When the energization of the solenoid 20 is in the ON state, the movable iron core 21 moves upward as shown in FIG. 5B, and the movable protrusion 22 moves upward by the action of the movable iron core 21. Thus, the upper surface of the movable protrusion 22 comes into contact with the bottom surface of the water supply valve 14 and presses upward. When the water supply valve 14 is lifted to a predetermined height, the upper surface of the locking projection 23 and the lower surface of the packing 26 come into contact with each other, and the movable projection 22 stops, so that the valve seat 16 and the valve portion 17 are stopped. Thus, the water in the water supply tank 12 flows out, and the water in the water supply tank 12 can be supplied into the inner tray 9 from the opening 15.

Next, the control in the mist operation in this embodiment will be described based on the flowchart of FIG.
First, when an operation switch (not shown) on the operation unit 7 is turned on to start operation, the control unit 50 confirms whether the drain valve 46 is closed (step S101), and the drain valve 46 is not closed. If the drain valve 46 is not closed, the drain valve 46 is closed (step S102) so that the water in the inner tray 9 does not flow into the drain tank 5.

  When the drain valve 46 is closed, the control unit 50 switches the energization of the solenoid 20 to the ON state and moves the movable iron core 21 upward (step S103), and the water supply valve 14 by the movable protrusion 22 operated by the movable iron core 21. Is pushed upward to cause the water in the water supply tank 12 to flow into the inner tray 9 from the opening 15.

  When the energization of the solenoid 20 is switched to the ON state in step S103, the control unit 50 determines whether or not the water storage sensor 38 is switched to the OFF state (step S104), and if the water storage sensor 38 is switched to the OFF state, It is determined that a predetermined amount or more of water has flowed into the tray 9 and the mist operation can be started. To start the mist operation (step S105).

  When the mist operation is started in step S105, the control unit 50 operates the operation switch (not shown) on the operation unit 7 again, or the water in the water supply tank 12 runs out, and the water storage sensor 38 is turned on. Thus, it is determined whether the stop condition for the mist operation is satisfied (step S106). If the stop condition for the mist operation is satisfied, the energization of the solenoid 20 is switched to the OFF state, thereby moving the movable core 21 to the original position. When the movable iron core 21 is lowered, the movable protrusion 22 is similarly lowered, and the water supply valve 14 is urged by the weight of the water and the elasticity of the water supply spring 18 to be closed, so that the opening 15 of the water supply tank 12 is closed. Water is prevented from flowing out of the water (step S107).

  When the energization of the solenoid 20 is switched to the OFF state in step S107, the control unit 50 confirms the ON / OFF state of the drainage sensor 47, determines whether the drainage sensor 47 is OFF (step S108), and the drainage sensor 47. If the drainage sensor 47 is in the ON state, an error is notified that the inside of the drainage tank 5 is full (step S109).

  If the drainage sensor 47 is in the OFF state in step S108, the control unit 50 opens the drainage valve 46 and starts the drainage operation to drain the water in the inner tray 9 (step S110), and the time counting means 53 counts it. When the time elapsed since the drain valve 46 was opened exceeds a predetermined time or the water storage sensor 38 is switched to the ON state, it is determined that the drainage in the inner tray 9 has been completed, and the blower fan 34 is When the drying operation for drying the inner tray 9 and its surroundings is started by driving at the number of revolutions (step S111), and the time elapsed since the blower fan 34 counted by the time measuring means 53 has been driven has passed a predetermined time or more. If it judges, the ventilation fan 34 will be stopped and a driving | operation will be complete | finished.

  If an error is notified that the drain tank 5 is full in step S109, the control unit 50 determines whether an operation switch (not shown) on the operation unit 7 is operated, and stops the error notification when the operation switch is operated. Let Thereafter, when the operation switch is operated again, it is determined whether or not the drain sensor 47 is in the OFF state. If the drain sensor 47 is in the OFF state, the drain valve 46 is opened because the drain tank 5 is not full and the drain operation in step S110. To proceed to the subsequent steps.

  As described above, when the mist operation starts, the energization of the solenoid 20 is switched to the ON state, the water supply valve 14 is pressed upward, the water in the water supply tank 12 is supplied into the inner tray 9, and the mist operation ends. Then, the solenoid 20 is turned off and the water supply valve 14 is returned to the original position to prevent water supply from the water supply tank 12 and the drain valve 46 is opened to drain the water in the inner tray 9. Since the water is drained, the water flowing into the inner tray 9 from the water supply tank 12 can be surely stopped when the mist operation is completed, and the water in the inner tray 9 can be drained into the drain tank 5. It is not necessary to take out the water supply tank 12 from the tank storage chamber 19 and the usability is improved, and the mist operation can be performed with clean water reliably at every mist operation. Is a basis.

  If the drainage sensor 47 is in an ON state after the mist operation is completed, the drainage valve 46 is not opened because the drainage tank 5 is full, and an error is notified. Does not flow in and the situation where water overflows from the drain tank 5 can be prevented, and the vicinity of the installation surface of the instrument body 1 does not get wet.

  In addition, although it demonstrated by the structure using the solenoid 20 and the movable protrusion 22 which operate the movable iron core 21 by supplying with electricity as an opening / closing means of the water supply valve 14, it is not restricted to this, For example, it is movable with the motor driven by supplying with electricity. A mechanism capable of pressing the projection 22 is installed, and when the mist operation starts, the energization of the motor is turned on to press the movable projection 22 and the water supply valve 14 to press the water in the water supply tank 12. When the mist operation is completed after being supplied into the inner tray 9, the motor is turned off and the movable projection 22 is returned to the original position, and the water supply valve 14 is lowered to discharge water from the water supply tank 12. In addition, any actuator that can change the operation of the water supply valve 14 by energization ON / OFF may be used.

  In addition, a drain switch is provided on the operation unit 7 of the instrument body 1 to open the drain valve 46 and allow the water in the inner tray 9 to flow into the drain tank 5 when operated by the user. If the drain switch is operated after the end, the control may be performed to open the drain valve 46 after switching the energization of the solenoid 20 to the OFF state. When the drain switch is operated, the water supply valve 14 is returned to the original position. After returning, the drain valve 46 is opened to drain the water in the inner case 9, so there is no possibility that the water in the water supply tank 12 flows into the drain tank 5, and the water overflows from the drain tank 5 and the appliance body 1. It is possible to reliably prevent the installation surface of the battery from getting wet.

  Further, the structure of the solenoid 20 used in the description of the present embodiment, the timing for turning on the energization of the solenoid 20 and the like are examples, and the respective structures and numerical values are changed without departing from the gist of the present invention. Is possible.
