Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a humidifier that performs humidification by blowing air through a humidifying unit containing water.

Conventional humidifiers of this kind have a wind guide tube installed in the upper part of an outer box that has a water storage tank at the inner bottom, a motor arranged inside the air guide tube, and a motor installed inside the water tank at the lower end of the motor rotating shaft. A tapered water suction pipe with a large number of holes for sucking in water, pumping it up, and scattering it outward is installed, and a breathable humidifying body, such as ether, is attached so as to surround this water suction pipe. A humidifying body made of urethane foam is arranged inside the outer box, and the humidifying body absorbs water by receiving the water splashed from the water absorption pipe. The attached air blower blade sucks in outside air from the intake port arranged on the side of the outer box, and after passing through the humidifying body, humid air is discharged from the upper discharge port of the air guide tube. It is configured to do so. It is desirable that the humidifying body uniformly receives the splashed water and contains water, and it is necessary that the water be uniformly scattered to the humidifying body from the many holes provided on the side of the water absorption pipe. be. On the other hand, if we closely observe the water pumping inside the water suction pipe, we can see that the water rising inside the water suction pipe forms a spiral line of water on the inner surface of the side of the water suction pipe, and once formed, the water channel is formed by resin molding. Since it blends better with the inner surface of the water suction pipe, which is made of aluminum, it is easier to create waterways in the same place. Therefore, of the many holes provided on the side of the water suction pipe, water is actually discharged from only a few of the holes that coincide with the spiral waterway. In order to obtain the amount of humidification, if the humidifying body is made larger and the water suction pipe becomes longer, there will be a part where the water splashed from the water suction pipe will not come out, and the water content of the humidifying member will be poor in this part. Therefore, in extreme cases, there may be dry areas in the humidifying member, and the incoming air will concentrate and pass through these dry areas with low air resistance, resulting in a problem that the humidification efficiency will deteriorate. For example, actual measurements have shown that when about 1/5 of the surface area of the humidifying member is dry, the amount of humidification decreases to about 2/3. In particular, when the humidifying member is made of ether-based urethane foam or the like, the above-mentioned problems are more pronounced because of its high water repellency.

The present invention was made in view of the above circumstances, and
The purpose of this is to provide a stepped section on the hollow inner surface below the hole position of the tapered hollow water suction pipe, and by applying strong centrifugal force at the stepped section to the water pumped inside the water suction pipe, cancel out the helical rising water channel. The spray water is sent uniformly from each hole to the humidifying member, and the humidifying member is uniformly hydrated.
An object of the present invention is to provide a humidifier capable of improving humidification effects.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, 1 has an intake port 2 on the side,
The outer box has a discharge port 3 and an air guide tube 4 arranged on its upper surface, and a water storage tank 5 at its inner bottom, which is detachably attached to the outer box 1. 6 is for sequentially replenishing water into the water tank 5, which has decreased due to humidification in the water supply tank, to maintain the water level in the water tank 5. 7
A motor is attached to the air guide tube 4 via a support arm 8, and has a rotating shaft 7a projecting downward, and a blower blade 9 and a hollow water suction pipe 10, which will be described later, are fitted with screws. Reference numeral 11 denotes a humidifying body made of ether-based urethane foam, etc., which is placed in the water storage tank 5 so as to surround the water absorption pipe 10.
The air guide tube 4 is placed on the inner bottom of the air guide tube 4, and its upper end is placed close to the lower end of the air guide tube 4. Now, the water suction pipe 10 will be described with reference to FIG. 2. Reference numeral 12 has a tapered shape that gradually increases in diameter facing upward. The main part is a vertically long cylindrical pipe, and there are a plurality of scattering ports 13a, 13 in the middle.
b, ... are provided, and scattering ports 13a, 13b are provided.
In correspondence with..., stepped portions 14a, 14b are formed on the hollow inner wall.
...is constructed directly below each scattering port. In addition, pipe main part 1
A water suction port 15 is provided at the bottom of the lower end of 2, and a threaded portion 1 is provided at the upper end to be screwed to the motor rotation shaft 7a.
A water suction pipe support arm 17 having a
The upper surface openings of the two are closed-fitted to form an integral structure.

Next, the operation of this embodiment having the above configuration will be explained. A predetermined amount of water 18 is stored in the water storage tank 5 at the water supply tank 6.
When water is supplied, the lower ends of the water absorption pipe 10 and the humidifying member 11 are immersed in the water. The water suction pipe 10 rotates as the motor 7 rotates, and the water 18 in the water tank 5 is sucked in from the water suction port 15 by the rotating centrifugal force of the water suction pipe, and the water is pumped up while drawing a spiral waterway along its inner wall. be done. When the helical waterway reaches the stepped portion 14a of the water suction pipe 11, the centrifugal force increases rapidly at this stepped portion, so the helical waterway is obliterated and the annular water flows along the stepped portion. A scattering port 13 that forms a pool and is disposed close to the stepped portion.
A part of the pumped water is discharged toward the humidifying member 11 from a. Furthermore, the pumped water that has not been discharged is sequentially affected by the same effect at the stepped portions 14b...
Discharge from each scattering port. In addition, in the vicinity of the upper end of the water suction pipe 10, pumped water that has not been discharged from the holes of the intermediate scattering ports 13a, 13b, etc. accumulates and is distributed in an annular shape within the pipe. You can get splashed water just by placing the . In this way, the humidifying member 11 uniformly receives the scattered water from each of the scattering ports 13a, 13b, . . . 13z of the water absorption pipe 10, and becomes hydrated over the entire surface. On the other hand, as the blower blades 9 rotate, external air 19 passes through the humidifying member 11 via the intake port 2 and becomes humid air, which is then discharged from the discharge port 3.

As described above, according to the present invention, since the stepped portion is formed directly below each splashing port, the pumping water channel is canceled by the stepped portion, and an annular water pool is formed along the stepped portion. Because of this, from each scattering port,
A constant amount of water can be obtained. Therefore, the humidifying member uniformly contains water over the entire surface and does not produce dry areas that reduce humidifying efficiency, so that a stable amount of humidification can be obtained. In addition, the entire helical waterway is not affected by changes in the rotational speed of the motor or changes in the centrifugal force caused by the eccentricity of the water suction pipe installation, and an annular water puddle is formed along the step. Since each splashing port acts effectively by forming a part, it has the advantage that the number of splashing ports can be reduced to 1/2 or less compared to a water suction pipe without a stepped part.
