Description

[Detailed explanation of the idea] The present invention relates to an improved structure of an evaporative humidifier.

This type of humidifier has a rotary filter that absorbs water placed in the air passage, and absorbs moisture in the air that is then discharged.

However, although the above-mentioned filter has a certain amount of interior, it has a drawback that the amount of moisture absorption cannot be increased if the area through which the air passes is limited.

This disadvantage particularly occurs when a propeller-type fan is used, and at the same time, since the motor of this fan is often located in the air passage, there is a disadvantage that the motor is deteriorated by the air that absorbs moisture.

The present invention has been developed to eliminate the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a container body consisting of an upper box body 2 fitted into the upper opening of a lower box body 3, and handles 4 for carrying it on both sides of the lower box body 3.
, 4 are fixed.

Here, the upper box body 2 has an operation knob 51 for an electrical component 5 built-in for controlling two motors, etc., which will be described later, on the upper side, an exhaust hole 6 in the center of the upper surface, and other parts on the upper surface. An insertion hole 8 for a drop type water supply tank 7 is provided on each side.

Further, the lower box body 3 has a water tank 9 formed on its bottom surface, and a seating portion 10 on the other side of the bottom surface on which the tank 7 is seated to supply water, and air intake holes 11 on the side and front and rear surfaces.
...... is established.

12. 12... are holding plates erected upward from both sides of the bottom of the lower box body 3, and four rotors 13... are suspended at each interval. A wide water absorption filter 14 is rotatably mounted, and this holding plate 12゜1
2 has bearing portions 15 for pivotally supporting both ends of the four rotors 13.

Furthermore, the four rotors 13 mentioned above are arranged two each at the top and bottom, and one rotor 1 at the top
3 protrudes from the holding plate 12 with one end thereof directed toward one side, and serves as a drive shaft 16 to secure a drive gear 17.

18 is a boss integrally formed to protrude downward from one side inner surface of the upper box body 2, and a horizontal mounting board 19 is fixed to the tip of the boss.

Reference numeral 20 denotes an abbreviated support plate fixed downwardly with screws or the like to the lower surface of the mounting board 19 in the center thereof, and the first motor 21 is supported in a suspended manner on its vertical piece. .

22 is the electrical component 5 and the first
A cover that covers the motor 21 including the motor 21, and is fixed to one side of the mounting board 19 with a screw or the like, and has a through hole 23 formed approximately in the center of its lower surface to face the drive gear 17 from above;
A bulging portion 24 is formed that hangs down and bulges out toward the water tank 9 from one end of the through hole 23 .

25. 25 is a guide tube that is installed on the inner surface of the cover 22 so as to straddle the through hole 23 in the front and back, and has a vertical groove 2 that opens in one side.
6.26.

27 is a support frame located above the through hole 23, and the cover 22
A vertical plate 29 to which the second motor 28 is attached and hangs down inside the bulge 24, and a horizontal piece 3 of the support plate 20 extending in the other side direction.
The top plate 31 located below 0, and the tip end connected to the vertical groove 26,
26 and two side plates 32, 32 slidably fitted within the two sides.

Furthermore, this support frame 27 is provided with tongue pieces 33, 33 that project horizontally into the through hole 23 at the lower ends of the side plates 32, 32,
Upper end 3 of the retaining plate 12 inserted into the through hole 23 from below
This tongue piece 33.33 is placed on 4.

Also, a connecting hole 35 is provided in the center of the top plate 31 of this support frame 27.
At the same time, the horizontal piece 30 is provided with a protruding connecting rod 36 that is slidably inserted into the connecting hole 35, and the connecting rod 36 is equipped with a coil that constantly biases the top plate 31 downward. A spring 37 is wound around it.

This support frame 27 thus has an upper end 34 with tongues 33.33.
By inserting the connecting rod 36 and the connecting hole 35,
Further, by fitting the side plates 32, 32 into the vertical grooves 26 of the guide cylinder 25, movement in the left and right directions and in the front and rear directions is restricted, and although vertical movement is possible, it is loosely restricted within the elasticity of the coil spring 37.

38 is fixed to the rotating shaft of the second motor 28 and is connected to the through hole 2.
The transmission gear facing downward from 3 and the driving gear 1 from above
7 to transmit the rotation of the second motor 28, but if there is a dimensional variation between the upper box 2 and the lower box 3, the mesh will mesh against the elasticity of the coil spring 37. .

In addition, for this purpose, the transmission gear 38 is connected to the drive gear 17 at the time of design.
When meshing, the coil spring 37 is compressed to some extent so that it can absorb any variation in dimensions.

In addition, when the drive gear 17 is locked for some reason, the transmission gear 38 moves upward against the elasticity of the spring 38 to release the meshing, and it is also possible to avoid overload operation of the second motor 28. be.

39 is above the water absorption filter 14 and the exhaled air 7L6
It is a horizontal flow fan disposed horizontally below, and the rotation of the first motor 21 is transmitted by a transmission shaft passing through the side surface of the cover 22, and a water absorption filter 14 is inserted between the intake holes 11... A ventilation path leading to the exhaust hole 6 is formed therebetween.

Therefore, in the humidifier of the present invention, when the filter 14 that has absorbed water in the water tank 9 rotates and the horizontal flow fan 39 rotates, indoor air enters the air passage through the intake holes 11 and almost completely fills the filter 14. It comes into contact with the surroundings almost evenly, absorbs moisture, and releases it into the room from the exhaust hole 6.

During this time, the electrical components 5, the first motor 21 and the second motor 28
Since it is inside the cover 22, it is less exposed to moisture-absorbed air and less likely to deteriorate.

In addition, the water level in the water tank 9 is detected by a detection rod 41 as the vertical movement of the float 40, and when the water level is extremely low, the detection rod 41
operates the switch 42 inside the cover 22 to stop the humidification operation.

Furthermore, when replacing or cleaning the water absorption filter 14, the upper box 2 can be removed from the lower box 3 and the work can be easily done through the opening.

In this way, the evaporative humidifier according to the present invention uses a cross-flow fan, which prevents the air from concentrating locally on the filter, and the motor that rotates the fan and filter, as well as the control electrical equipment, are housed in the upper box. The side of the vessel was separated from the air passage by a cover and placed in one place.
These motors and electrical components are less likely to deteriorate due to moisture absorption and air flow, and furthermore, these motors and electrical components can be made compact.
