Description

[Detailed Description of the Invention] The present invention relates to an improvement of a humidifier that performs humidification by ventilation through a humidifying body having water absorption properties.

This type of conventional humidifier has a water storage tank inside the outer box, an air guide tube installed in the upper part of the outer box, and a rotating shaft that extends downward through the support arm into the air guide tube. Install the oriented drive motor,
A suction pipe, which is a rotating body, is attached to the rotating shaft of the drive motor, and the suction pipe sucks up the water in the water tank and scatters it outward. a cylindrical humidifying body having water absorbing properties that receives splashed water; and a blower blade is attached to the rotating shaft of the drive motor so as to be located above the suction pipe;
This air blowing blade sucks in outside air through the inlet on the side of the outer box and through the humidifier body, and then discharges it into the room from the outlet at the top of the air guide tube, thereby humidifying the room. It is the composition.

However, in the above-mentioned conventional configuration, since the drive motor and support arm are present in the air blowing path of the air blowing blade, the air flow is obstructed by these, resulting in poor air blowing efficiency and, therefore, a problem that the humidification efficiency deteriorates. In addition, since humid wind flows around the drive motor, the drive motor must have a moisture-proof structure, and it is necessary to use an expensive drive motor.

The present invention was developed in view of the above circumstances, and its purpose is to provide a rotatable drive shaft that penetrates the bottom of the water tank in a watertight manner, and to rotate the drive shaft to scatter the water in the water tank. A humidifying body is provided to surround the rotary body, and the humidifying body is rotated by the drive shaft to suck outside air through the inlet on the side of the outer box and through the humidifying body. Humidification efficiency is improved by providing a configuration in which a blower blade that discharges air upward from the upper discharge port is provided opposite to the discharge port, and a drive motor for rotating this drive shaft is provided at the outer bottom of the water tank. To provide a humidifier which can achieve the following, can use an inexpensive drive motor without requiring a moisture-proof structure, and can uniformly humidify the entire room in which it is installed.

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

Reference numeral 7 denotes a flat container-shaped water storage tank mounted on the inner bottom of the outer box 1 via leg portions 8, and has an upwardly extending cylindrical portion 9 protruding from approximately the center of the bottom. A storage recess 10 is formed at the right end of the housing so as to bulge upward.

Reference numeral 11 denotes a water supply tank which is removably inserted into the outer box 1 through the opening 6 of the lid 3, and is designed to always supply water 12 to the water storage tank 7 up to a constant water level.

In this case, the upper end of the cylindrical portion 9 of the water tank 7 is set to protrude upwards to a greater extent than the water level of the water 12.

Reference numeral 13 denotes a drive shaft which is inserted into and supported by the cylindrical portion 9 of the water tank 7 through bearings 14 and 15 attached to the upper and lower ends thereof, and a driven pulley 16 is fitted and fixed to the lower end thereof.

Reference numeral 17 denotes a drive motor disposed and fixed in the storage recess 10 which is a part of the outer bottom of the water tank 7, with its rotating shaft 18 protruding downward, and the drive pulley 10 being fitted and fixed on the protruding end. A V-belt 20 is stretched between the drive pulley 19 and the driven pulley 16.

Reference numeral 21 denotes a suction pipe as a rotating body, which has a tapered cylindrical shape whose diameter becomes smaller as it goes downwards, and has a lower end opening as a suction port 22 and an upper end opening as a splash port 23 that widens. At the same time, a large number of ejection holes 24 are formed in the peripheral wall.

Then, this suction pipe 21 is connected to the shaft cylinder portion 9 and the drive shaft 13.
The splash opening 23 is attached to the upper end of the drive shaft 13 via a fitting 25.

In this case, the lower end of the suction pipe 21 is immersed in the water 12 in the water tank 7.

Reference numeral 26 represents a blower blade, and its boss portion 27 is connected to the drive shaft 1.
3 so as to be positioned inside the air guide tube 5, and is removably attached with a nut 28.

Reference numeral 29 denotes a water-absorbing humidifying body that stands upright at the inner bottom of the water tank 7 so as to surround the outer periphery of the suction pipe 21, and is made of polyester-based urethane foam and is similar to the air guide tube 5. It is formed into a cylindrical shape having the same inner diameter, and its upper end surface is brought close to the lower end surface of the air guiding tube 5.

By arranging and fixing the drive motor 17 in the storage recess 10 of the water tank 7, the drive motor 17 can move through the air passage from the humidifier body 29 to the discharge port 4, that is, inside the humidifier body 29 and the air guide. It is located in a region other than the inside of the cylinder 5 and is isolated from the inside of the water tank 7.

Note that 30 is a grill attached to the outlet 4 of the lid 3, and 31 is a wind direction piece provided to the inlet 2 of the outer box 1.

Next, the operation of this embodiment having the above configuration will be explained.

When the drive motor 17 is energized, its rotating shaft 18° drive boo IJ 19. V-belt 20. The suction pipe 21 and the blower blade 26 are rotationally driven via the driven pulley 16 and the drive shaft 13 .

Then, when the suction pipe 21 is rotated, the suction pipe 21 sucks and pumps up the water 12 in the water tank 7 through the suction port 22, and during the pumping process, some of the water is scattered outward from the spout hole 24. At the same time, the remaining water is scattered outward from the splash opening 23, and the scattered water is received and absorbed by the humidifying body 30.

On the other hand, when the blowing blade 26 is rotated, the blowing blade 26 passes through the suction port 2 and the humidifying body 29 into the external chamber 3.
The air of 2 is sucked in and then is discharged upward into the chamber 32 from the discharge port 4 through the wind guide tube 5.

Then, when the air passes through the humidifier body 29, it becomes humid and humidifies the inside of the room 32.

As described above, according to this embodiment, the drive shaft 13 is inserted and supported in a watertight manner in the shaft cylinder portion 9 protruding from the bottom of the water tank 7, and the suction pipe 21 and the blower blade 26 are connected to the drive shaft 13. The drive motor 17 is mounted so as to rotate together, and furthermore, the drive motor 17 is arranged and fixed in the storage recess 10 formed at the bottom of the water tank 7.
This drive motor 17 drives the drive boo IJ 19. The drive shaft 13 is configured to be rotationally driven via the V-bell I.20 and the driven punch 16.

Therefore, since there is no drive motor or support arm in the air guiding tube 5, which is the air path of the air blowing blades 26, as in the conventional case, the air flow of the air blowing blades 26 is not obstructed and the air blowing efficiency can be improved. This makes it possible to improve humidification efficiency.

Further, since the drive motor 17 is located in the storage recess 10 of the water tank 7 and is isolated from the inside of the water tank 7, humid air circulates around the drive motor 17 as in the conventional case. Therefore, the drive motor 17 does not require a moisture-proof structure, and an ordinary inexpensive motor can be used.

Moreover, as mentioned above, since the drive motor 17 is not present in the wind guide tube 5 of the lid body 3, there is an advantage that the overall height dimension can be reduced compared to the conventional one. 7 can be attached by using the space formed on the right side of the outer box 1 for attaching the water tank 11, so that the left and right length dimensions are not increased compared to the conventional case.

Further, a discharge port 4 is provided in the upper part of the outer box 1, and a blower blade 26 is disposed opposite to the discharge port 4, thereby blowing humid air from the discharge port 4 through the humidifying body 29. Since the air is discharged upward, the air from the discharge port 4 can be distributed throughout the entire chamber 32, which is the installation location, in addition to the high air blowing efficiency as described above. Can humidify evenly.

That is, 33 is an outer box with openings on both the upper and lower sides, and an inlet 35 having a wind direction piece 34 is formed at the upper side of the outer box.
The interior is partitioned vertically and watertightly by a partition plate 36, and the upper chamber is used as a water storage tank 37.

Reference numeral 38 denotes a lid which is a part of the outer box 1 and is removably attached to the upper opening of the outer box 33, and has a guide piece 3 approximately in the center thereof.
A discharge port 40 having a relatively large diameter and having a short cylindrical shape and projecting vertically is formed.

Reference numeral 41 denotes a cylindrical shaft portion integrally projecting upward from approximately the center of the partition plate 36 that is the bottom of the water storage tank 37, and its upper end is lower than the water level of the water 12 supplied into the water storage tank 37. Located above.

Reference numeral 42 denotes a drive motor which is attached via a mounting boss section 43 etc. to the substantially central part of the lower surface of the partition plate 36, which is the outer bottom of the water tank 37. The shaft cylindrical portion 41 is inserted and supported through the bearings 14 and 15, and the suction port 21 and the blower blade 26 are attached to the upper end of the rotating shaft 44 in the same manner as in the previous embodiment.

Then, the humidifier body 29 is arranged so as to surround the outer periphery of the suction pipe 21, and its upper end is fitted and attached to the lower outer periphery of the discharge port 40, and the lower end is immersed in the water 12.

In this embodiment as well, the drive motor 42 is isolated from the inside of the water tank 37 by the partition plate 36 and is located at a location other than the air passage from the humidifier body 29 to the discharge port 40. Therefore, it is possible to obtain substantially the same effects as in the above embodiment.
