[Detailed description of the invention] The present invention relates to a ventilation type humidifier that performs humidification by passing outside air through a humidifying tube in a moist state.The purpose of the invention is to increase the amount of humidification, thereby improving humidification performance. It is to provide the equipment.

An embodiment of the present invention will be described below based on the drawings.

1 is a lower case whose inner bottom is a water tank 1a; 2 is an upper case with an open bottom; this upper case 2 is placed on the lower case 1, and an upper case 2 and a lower case 1 constitute a main case 3. It's intimidating.

Reference numeral 4 denotes a cylindrical wind guide tube extending downward on the inner upper surface of the upper case 2, and 5 denotes a discharge port formed on the upper surface of the upper case so as to communicate with the wind guide tube 4. A grill 6 that discharges humidified air is fitted.

Reference numeral 7 denotes a motor attached to the air guide tube 4 via a support frame 8. The rotating shaft 9 of this motor 7 is directed downward, and its tip end is slightly away from the lower end opening of the air guide tube 4. protrudes downward.

Reference numeral 10 denotes a blowing blade fitted to the middle part of the rotating shaft 9, which forms a fan device 11 together with the motor 7, and when driven to rotate by the motor 7, it blows outside air to one side of the upper case 2. Air is sucked into the main body case 3 through a plurality of suction ports 12 (only one is shown), and is discharged to the outside through the air guide tube 4 and the grille 6 in this order.

Reference numeral 13 denotes a water pumping tube with a closed upper end and a tapered inner circumferential surface that gradually expands upward. immersed in water.

When the water pumping tube 13 is rotated, water is sucked up along its tapered inner circumferential surface by centrifugal force and is scattered outward through the water spray holes 14 formed in multiple stages up and down in the water pumping tube 13. It has become so.

Now, 15 is a bevel gear, which is rotatably fitted to the rotating shaft 9 via a bearing 16 and rotatably supported on the upper surface of the water pumping cylinder 13 via a rolling bearing 17.

Reference numeral 18 denotes a plurality of support bones extending radially outward from the outer circumferential surface of the bevel gear 15, the end portions of which are connected to the annular frame 19.
is connected to.

The annular frame 19 has an H-shaped cross section with a roof-shaped groove 19a and a lower annular groove 19b on both upper and lower surfaces, and the roof-shaped groove 19a is loosely fitted into the lower end of the wind guiding tube 4.

Reference numeral 20 denotes a plurality of support bones whose upper ends are attached to the inner peripheral side of the lower surface of the annular frame 19 and whose lower ends are bent outward in a substantially U-shape. It is immersed in water in the water tank 1a, and forms a rotating cage 21 together with the support bone 18 and the annular frame 19.

Reference numeral 22 denotes a humidifying cylinder made of, for example, soft polyurethane foam, which has both air permeability and water absorption properties.The upper peripheral edge of this cylinder is fitted into the lower annular groove 19b of the annular frame 19, and the lower peripheral edge is inserted into the U of the support frame 20. This humidifying cylinder 22 is fixed to the rotating cage 21 by fitting into the character-shaped portion 20a.

The humidifying tube 22 surrounds the water pumping tube 13 and is wetted by being splashed with water from the water pumping tube 13.

Reference numeral 23 denotes a motor with a speed reduction mechanism attached to the outer periphery of the wind guide tube 4. The output shaft 24 of this motor projects horizontally into the wind guide tube 4, and a bevel gear 25 is fitted to its tip. This bevel gear 25 meshes with the bevel gear 15 orthogonally.

When the motor 23 is energized, the bevel gear 25 is rotated via the speed reduction mechanism, and this rotation is transmitted to the bevel gear 15 to rotate the rotary basket 21 and, in turn, the humidifying cylinder 22.

The motor 23, the bevel gear 15, and the bevel gear 25 constitute a drive device 26 that rotationally drives the humidifying tube 22.

Note that the rotation direction of the humidifying cylinder 22 is set to be opposite to that of the water pumping cylinder 13.

Reference numerals 27 and 27 denote a pair of brush members, which are cleaning members, that are installed upright on the inner bottom surface of the water tank 1a so as to contact the inner and outer circumferential surfaces of the humidifying cylinder 22. When the humidifying cylinder 22 is rotationally driven, these brush members 27 .27 slides relatively on the inner and outer circumferential surfaces of the humidifying cylinder 22, and collects fine dust that is sucked into the outside air and adheres to the outer circumferential surface of the humidifying cylinder 22 and water scale that adheres to the inner circumferential surface of the humidifying cylinder 22. etc. are removed.

Next, the operation of the above configuration will be explained.

When both motors 7 and 23 are energized, the blower blade 10 and the water pump 13 are rotated, and the humidifying cylinder 22 is rotated so that the water pump 13 is rotated.
It is rotated in the direction opposite to the turning direction.

As the water pumping tube 13 rotates, the water in the water tank 1a is sucked up along the inner peripheral surface of the water pumping tube 13, and is splashed from the water sprinkling hole 14 onto the rotating humidifying tube 22, making it moist. .

On the other hand, as the blower blades 10 rotate, outside air is sucked into the main body case 3 through the inlet 12 and the humidifying cylinder 22 is rotated.
pass through.

In this process, the outside air becomes humidified and is discharged outside the vessel through the wind guide tube 4 and the grill 6 in order, thereby humidifying the room.

By the way, due to structural or design restrictions, the outside air inlet is
It is difficult to form them evenly around the entire circumference of the main body case, and they are often formed in one place, or even if they are not concentrated, they are formed at appropriate intervals, and the air sucked in from the intake port tends to pass through the humidifying tube near the inlet.

However, in the past, the humidifying tube was fixedly attached to the main body case, so that among the circumferential parts of the humidifying tube, the area near the inlet, that is, the area through which the most intake air passes, becomes locally semi-dry.

As a result, the amount of moisture in the air passing through the humidifying cylinder is reduced overall, resulting in a deterioration in humidifying performance.

On the other hand, in this embodiment, since the humidifying cylinder 22 is configured to be rotated around the water pumping cylinder 13 by the drive device 26, even if the suction ports 12 are formed concentratedly in a specific part of the main body case 3, the As the humidifying cylinder 22 rotates, the outside air taken in through the mouth 12 passes through each part of the humidifying cylinder 22 in turn and evenly.

Therefore, only a specific part of the humidifying cylinder 22 is not left in a semi-dry state, and the entire humidifying cylinder 22 is in a moderately uniformly moist state, and an equal amount of air passes through each part, which is ideal operation. As a result, the amount of humidification can be increased, and humidification performance can be greatly improved.

In addition, in the past, the water that was splashed from the water pump and splashed onto the humidifying tube was concentrated into several streams as it flowed down along the inner circumferential surface of the humidifying tube because the humidifying tube was stationary. There was a possibility that the entire cylinder could not be uniformly moistened.

On the other hand, in this embodiment, since the humidifying tube 22 rotates, the water splashed onto the humidifying tube 22 does not tend to be concentrated in several streams, and even if it is concentrated, it does not flow in a wide stream. Since the flow becomes a belt-like flow and flows down in an inclined state, the inner circumferential surface of the humidifying tube 22 can be completely moistened, and the moist state of the humidifying tube 22 can be made more uniform than in the past.

In this embodiment, a dedicated motor 23 for rotationally driving the humidifying cylinder 22 is provided, but the invention is not limited to this, and the rotation of the motor 7 can be transmitted to the humidifying cylinder 22 by an appropriate rotation transmission means such as a gear train. may be driven to rotate.

Further, although the brush member 27 is fixed to the inner bottom surface of the water tank 1a, the brush member 27 is provided so as to be movable toward and away from the humidifying cylinder 22, and if necessary, the brush member 27 can be moved from the humidifying cylinder by an external operation. 22 may be configured so as to be brought into sliding contact.

As explained above, the present invention provides a rotatable humidifying tube,
A special feature of this system is that it is configured to be rotated by a drive device.As a result, even if the outside air intake ports are locally concentrated, each part of the humidifying tube is evenly moistened. Therefore, it is possible to provide a ventilation type humidifier that can increase the amount of humidification by ventilation, thereby improving humidification performance.
