  As described above, the humidifier is provided with a motor. And when a humidifier falls, there exists a possibility that the water collected in the said water tray may leak, and the said motor may be wetted. This point will be described in detail. When the humidifier falls over so that the fan inlet side faces downward, the water stored in the water tray flows into the lower space of the fan inlet. However, since the air intake side of the fan has a sufficient space for sucking the airflow, there is little possibility that the water that has flowed in flows into the motor or the like from the air intake. In addition, when the humidifier falls over so that the fan inlet side faces upward, the water stored in the water tray is less likely to flow into the motor or the like from the inlet port. On the other hand, the humidifier may fall over so that the air intake port of the fan faces sideways. At this time, if the humidifier falls over so that the water tank side is downward, the water stored in the water tray flows into the space that houses the water tank, so there is a possibility that it flows into the motor or the like from the intake port. small. Therefore, when the humidifier falls in these directions, the motor or the like can be prevented from getting wet if the humidifier is quickly raised before water exudes from the gap between the components. On the other hand, when the humidifier falls over so that the water tank side is on the upper side, depending on the layout of the fan, water stored in the water tray may flow into the fan side from the intake port. is there. In this case, even if the humidifier is quickly raised, the motor or the like may be wetted.

In this embodiment, a communication hole 38 provided on one side of the tray side duct 26 is provided so as to communicate with the opening end surface 37.

  A fan 39 is provided at the boundary between the primary-side wet air passage 21 and the secondary-side wet air passage 22 that follows the primary-side wet air passage 21. The fan 39 is mounted on the upper portion of the humidifier body 1 so as to be disposed above the humidifying means 18. The fan 39 is a centrifugal fan such as a sirocco fan in which a plurality of blades 40 are annularly and intermittently arranged along the outer periphery of the disc portion 41. Further, the center of the disk portion 41 of the fan 39 is connected to the rotating shaft 42 of the blower motor. That is, the rotating shaft 42 of the air blower motor and the disc portion 41 are coaxial. The blower motor and the fan 39 constitute an electric blower. In addition, the said electric blower is arrange | positioned in the said humidifier main body 1 so that the central axis 41A of the said rotating shaft 42 and the disc part 41 may become horizontal and the front-back direction. In addition, a suction portion 39 </ b> A that is a primary side of the fan 39 of the electric blower is configured to face the front panel 2. The primary wet air passage 21 formed by the gap C is provided between the back side of the front panel 2 and the suction portion 39A. In addition, the secondary side of the fan 39 of the electric blower is formed by the entire circumference of the blade 40 in the vertical and horizontal directions.

  A partition member 43 for partitioning the primary side and the secondary side of the fan 39 is provided on the humidifier body 1 above the humidifying means 18. The partition member 43 includes a vertical partition member 44 provided on the front side of the fan 39 and a horizontal partition member 32 connected to a lower portion of the vertical partition member 44 and extending horizontally rearward. The vertical partition member 44 is formed with an intake port 44A corresponding to the suction portion 39A of the fan 39. The lower end edge of the vertical partition member 44, that is, the front end edge of the horizontal partition member 32 is opened by a gap C and communicates with the humidifying means 18 side.

  Thus, the primary-side humid air passage 21 is formed between the humidifying means 18 and the fan 39 from below the horizontal partition member 32 to the front of the vertical partition member 44. On the other hand, the secondary wet air passage 22 is formed between the secondary side of the fan 39 and the blower outlet 10, behind the vertical partition member 44 and above the horizontal partition member 32.

  Further, the primary-side wet air passage 21 has a lower wet air passage 45 formed below the lower edge of the vertical partition member 44, that is, the front end of the horizontal partition member 32, and the vertical partition member. An upper wet air passage 46 is formed above the lower edge of 44. One side end face 45A, which is the first side wall portion of the lower wet air passage 45, faces the machine room 31 of the humidifier body 1, and the other end face 45B of the lower wet air passage 45 is formed on the tray 17. It faces the partition part 25. On the other hand, the one side end face 46 </ b> A which is the second side wall portion of the upper wet air passage 46 is erected substantially at the middle of the lateral width D of the machine room 31. The other end face 46B of the upper wet air passage 46 is provided so as to face the main body side duct 14 side. The upper end surface 46C of the upper wet air passage 46 faces the circuit board 9 side. The other end face 46B and the upper end face 46C are continuously connected in an arc shape.

  The other end face 45B of the lower wet air passage 45 and the other end face 46B of the upper wet air passage 46 are flush with each other. That is, there is no step between the other side end faces 45B and 46B. On the other hand, a stepped portion 47 is formed between one end face 45A of the lower wet air passage 45 and one end face 46A of the upper wet air passage 46. The level difference of the stepped portion 47 is “E−F” when the lateral width of the lower wet air passage 45 is F and the lateral width of the upper wet air passage 46 is E. And this level | step difference is substantially equal to the half (D / 2) of the width | variety of the said machine room 31. FIG. Thus, a space having a volume of C × (E−F) × G (≈C × D × G ÷ 2) is formed on one side of the upper wet air passage 46. Note that G is the height of the upper humidification space 46.

  Next, the effect | action is demonstrated about the said structure. First, the user attaches the rotating drum 28 to which the breathable water retaining member 35 is attached to the water storage tank 27 of the tray 17, and then attaches the tray 17 to the humidifier body 1. And after putting water into the water tank 12 and closing the mouth with the cap portion 15, the lid member 11 is opened, the water tank 12 is inserted into the humidifier body 1, and the lid member again. 11 is closed. As a result, a water stop valve mechanism (not shown) in the cap 15 is opened by the protrusion 24, and the water in the water tank 12 flows out into the recess 23. Then, the water that has flowed out into the recess 23 flows into the water storage tank 27 through the water channel 19. As described above, the water level in the water storage tank 27 is kept substantially constant. Then, when water flows into the water storage tank 27 in this way, the air permeable water retaining member 35 of the rotating drum 28 attached to the water storage tank 27 is immersed and absorbs water.

  When the user operates the power switch of the operation unit 8, the heater 20, the drum rotating motor 29, and the air blowing motor are energized. When the heater 20 is energized, the heater 20 generates heat. Further, when the drum rotating motor 29 and the air blowing motor are energized, these motors are driven to rotate. Then, the rotary drum 28 is rotated via the drive gear 30 and the driven gear 36 by the rotational drive of the drum rotation motor 29. Then, as the rotating drum 28 rotates, the breathable water retaining member 35 held by the rotating drum 28 also rotates in a water-containing state.

  Furthermore, the fan 39 attached to the rotating shaft 42 also rotates as the blower motor rotates. As the fan 39 rotates, the primary-side wet air passage 21 becomes negative pressure. Due to this negative pressure, the air in the room where the humidifier is installed is sucked from the air inlet 7. The air sucked from the air inlet 7 is heated by the heater 20 to become hot air. The warm air is guided to the inside of the rotary drum 28 through the main body side duct 14 and the tray side duct 26, through the communication hole 38 of the partition portion 25, and the opening end surface 37. When the warm air flowing into the rotary drum 28 passes through the air permeable water retaining member 35, the water contained in the air permeable water retaining member 35 is vaporized to become wet air. The wet air is sucked into the fan 39 from the suction portion 39A through the lower wet air passage 45 and the upper wet air passage 46 of the primary side wet air passage 21. Further, the wet air sucked by the fan 39 is discharged into the room from the blowout port 10 through the secondary-side wet air passage 22.

  If the humidifier falls down so that the left side panel 4 side touches the floor, for example, when the user accidentally kicks off, the water W in the water storage tank 27 leaks as shown in FIG. Then, the air flows into the upper wet air passage 46 from the lower wet air passage 45. When the water W flows out from the intake port 44 </ b> A to the secondary wet air passage 22, the motor of the electric blower provided in the secondary wet air passage 22 may get wet. However, the water W is stored in the above-described volume space formed in the step portion 47. This makes it difficult for the water W to flow out from the intake port 44 </ b> A to the secondary wet air passage 22. For this reason, it can make it hard to make the said humidifier fail by making the motor of the said electric blower hard to get wet.

  When the humidifier falls so that the front panel 2 touches the floor, the width of the upper wet air passage 46 is widened by the stepped portion 47. Minutes lower. For this reason, since the distance from the water surface to the inlet 44 </ b> A at the time of falling can be increased, the water flowing from the humidifying means 18 into the primary wet air passage 21 is input to the secondary wet air passage 22. It can be made difficult to flow in.

  In addition, when the humidifier falls to the rear or the water tank 12 side, it is difficult for the water W to flow from the primary-side wet air passage 21 to the secondary-side wet air passage 22 via the intake port 44A. , As described above.

  As described above, in the embodiment, the upper humid air that is on the electric blower side from the one side end face 45A that is the first side wall portion of the lower moisture passage 45 that is the humidifying means 18 side of the primary side humid air passage 21. By forming the one side end face 46A, which is the second side wall portion of the passage 46, to be on the outside, the humidifier body 1 falls down and the water of the humidifying means 18 passes through the lower wet air passage 45 to the upper portion. Even if it leaks into the wet air passage 46, the leaked water W can be stored by the step portion 47. As a result, the water W flows out into the secondary wet air passage 22 and wets the motor of the electric blower. It is possible to suppress the risk of being lost.

  In addition, the primary wet air passage 21 is provided on one side of the humidifier body 1 in the side or in the depth direction, and the water tank 12 for supplying water to the humidifying means 18 is provided on the other side, and the one side end faces 45A, 46A. Is provided on one side of the primary-side humid air passage 21, so that when the humidifier body 1 falls down to one side, each one-side end face 45A provided on one side of the humidifier body 1; The water W flowing into the space of the stepped portion 47 constituted by the step 46A is accumulated, and the water W is prevented from flowing into the secondary wet air passage 22 so that the motor or the like of the electric blower is turned into the water W. It is possible to make the structure difficult to wet.

  Furthermore, since the width E in the same direction of the upper wet air passage 46 is formed larger than the width F in the one side / other side direction of the lower wet air passage 45, the primary wet air passage 21 is on the lower side. Since the water level in the upper wet air passage 46 when it falls down can be lowered and the distance from the water surface to the fan 39 can be increased, it flows from the humidifying means 18 into the primary wet air passage. It is possible to make it difficult for the water W to flow into the secondary wet air passage 22.

  FIG. 5 shows a second embodiment. The same parts as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In Example 2, the one side end face 45A which is the first side wall part and the one side end face 46A which is the second side wall part are connected by the arc-shaped step part 47 'in front view, The same operation effect as Example 1 is produced.

  As described above, the humidifier according to the present invention can be applied to various uses.
