  The present invention provides a humidifier having an operation unit on the top plate, and a partition plate is provided below the wiring board arranged immediately below the operation unit, and the bottom of the partition plate is inclined so that a predetermined portion is at the lowest point. A drainage hole is provided at the lowest point, and a waterproof wall is provided on the outer periphery of the partition plate. In addition, the partition plate is composed of a blower case of a blower means, and has a drainage path communicating from the drainage hole to the water tank portion.

  That is, water that has entered from the vicinity of the top plate flows toward the drainage hole provided at the lowest point due to the inclination of the bottom of the partition plate, and even if a large amount of water enters, it will surely flow into the drainage hole by the waterproof wall. The infiltrated water does not splash on the wiring board and passes through the drainage passage from the drainage hole and is reliably collected in the water tank. Therefore, it is possible to prevent various electrical components mounted on the wiring board from being damaged, and to prevent the floor, table or the like where the humidifier is installed from being infiltrated with water. Moreover, since the partition plate also serves as the air blowing case of the air blowing means, it is not necessary to add a new part, so that the part cost of the humidifier can be reduced.

  An embodiment of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, reference numeral 1 denotes an exterior case made of a resin material for the humidifier, and 2 is an operation unit located at the upper part of the exterior case 1 for controlling the operation of the humidifier. The blower outlet 3 for exhausting the humidified air humidified in 1 to the room | chamber interior is provided. Reference numeral 4 denotes a suction port for sucking room air into the exterior case 1, and reference numeral 5 denotes a carrying U-shaped handle that is attached around the operation unit so as to be raised and lowered.

  FIG. 2 is a longitudinal sectional configuration diagram of the humidifying device, 6 is a water tank unit that stores a certain amount of water supplied from a water supply tank (not shown), and 7 is a vaporizer as a humidifying means that absorbs and wets the water in the water tank unit 6. It is a filter. Reference numeral 8 denotes a blower as a blowing means, and reference numeral 9 denotes a warm air heater which is disposed between the suction port 4 and the vaporization filter 7 and heats the air sucked from the suction port 4 by the blower 8. That is, the ventilation path 10 including the suction port 4, the warm air heater 9, the vaporization filter 7, the blower 8, and the air outlet 3 is formed in the exterior case 1.

  FIG. 3 is an exploded perspective view of the humidifier, and is attached to the top plate 11 of the outer case 1 on the operation part 2 with the operation plate 12 attached, a U-shaped handle 5 for carrying, and the operation part 2 immediately below. A wiring board 13 is arranged. Furthermore, a partition plate 14 is provided below the wiring board 13. As shown in FIG. 2, the handle 5 can be raised and lowered by engaging the engaging portion 5 </ b> A of the handle 5 with the engaging portion 11 </ b> A formed integrally with the top plate 11, and the end of the handle 5 when raised. Is provided with an opening 11B communicating with the partition plate 14 below the engaging portion 11A so as not to interfere with the top plate 11.

  FIG. 4 is an enlarged perspective view of the partition plate 14. The partition plate 14 is inclined so that the center of the bottom is the lowest point, and a plurality of drain holes 14A are provided at the position of the lowest point. Further, a waterproof wall 14B having a certain height is provided on the outer periphery of the partition plate 14. In this embodiment, as shown in FIG. 2, the partition plate 14 also serves as a blower case 15 molded from a resin material in order to reduce the number of parts. As shown in FIG. A drainage path 16 that communicates from the hole 14 </ b> A to the water tank unit 6 through the blower case 15 is provided.

  Next, the operation in the above configuration will be described. When the humidifier is operated, water is first put into a water supply tank (not shown), which is inserted into the outer case 1 and installed at a designated position. As a result, a fixed amount of water flows from the water supply tank into the water tank 6 and water at a constant water level is stored. As a result, the vaporization filter 7 installed in the water tank unit 6 sucks and wets the water in the water tank unit 6 by capillary action.

  In this state, when the operation switch of the operation unit 2 is turned on and the target humidity is selected by the humidity setting switch, the blower 8 rotates, so that the indoor air is sucked into the outer case 1 from the suction port 4 and the vaporization filter 7 is turned on. When passing, it becomes humid air and is discharged from the outlet 3. Thereafter, according to the difference between the set humidity set by the humidity setting switch and the detected humidity detected by the humidity sensor, the humidification operation is automatically performed by controlling the rotation of the heater 9 for the hot air and the blower 8.

  By the way, when water is accidentally spilled on the operation unit 2 such as when water is supplied to the water supply tank, water enters the partition plate 14 from the opening 11B of the top plate 11 with which the handle 5 is engaged. However, the infiltrated water immediately flows toward the drain hole 14A provided at the lowest point due to the inclination of the bottom of the partition plate 14 (black arrow in FIG. 4). Even if a large amount of water enters the partition plate 14, the waterproof wall 14 </ b> B provided on the outer periphery of the partition plate 14 surely flows into the drain hole 14 </ b> A, so that the water splashes on the wiring board 13 and other parts. Is gone.

  Furthermore, since the water collected in the drain hole 14A passes through the drain path 16 and is reliably collected in the water tank section 6, it does not stay on the partition plate 14 and leaks out of the exterior case 1. No (black arrow in FIG. 5). Therefore, it is possible to prevent various electric parts mounted on the wiring board 13 from being damaged, and to prevent the floor, table or the like where the humidifier is installed from being infiltrated with water. Further, since the partition plate 14 also serves as the air blowing case 15 of the blower 8, it is not necessary to add a new part, so that the part cost of the humidifier can be reduced.
