Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidifier used to prevent a decrease in indoor humidity during winter heating, and an object of the present invention is to provide a humidifier with high humidification efficiency and little performance deterioration. do.

A conventional evaporative humidifier will be explained based on FIG. 3. 1 is a rotating drum, and a drum frame 2 of the rotating drum 1 is covered with a humidifying cloth 3. Further, one end of the rotary drum 1 is rotated by a motor 5 while being immersed in water in a water tank 4 provided below. A blower 6 blows air to the outside of the rotating drum 1. 7 is a casing.

To explain the operation of the conventional evaporative humidifier having the above configuration, during humidification operation, the humidifying cloth 3 is constantly rotated by the motor 5 while immersed in the water tank 4, and the humidifying cloth 3 is always impregnated with moisture. It is maintained in that condition. Air is blown from the outside of the rotary drum 1 having the humidifying cloth 3 in such a state, and when the wind passes through the humidifying cloth 3, evaporation of moisture is promoted and humidification is performed.

However, the drawbacks of conventional evaporative humidifiers are as follows: (1) The blown air needs to pass through the humidifying cloth twice, and the air blowing resistance is large, so that the effect of the air blowing is not sufficient.

<2> Since the rotating drum 1 is immersed in water, only about two-thirds of the total area of the humidifying cloth 3 works effectively, and a sufficient amount of humidification cannot be obtained.

<3> When the humidifying operation is stopped, about one-third of the humidifying cloth 3 is submerged in water, so the humidifying cloth 3 is easily clogged with water stains, etc., leading to a decrease in the amount of humidification. .

<4> In order to obtain the amount of humidification, it was necessary to make the rotating drum 1 large, and the casing of the entire humidifier was also large.

<5> Humidifying cloth 3 stretched over large rotating drum 1
Maintenance such as cleaning is not easy.

<6> In order to rotate the large rotary drum 1, a driving motor 5 is required, resulting in high cost.

The present invention comprises a bag-shaped humidifying cloth that is stretchable and breathable, impregnating the humidifying cloth with moisture, and blowing air from the inside of the humidifying cloth to the outside so as to pass through the humidifying cloth using an air blower. By evaporating the moisture impregnated into the humidifying cloth into the air, the drawbacks of the conventional humidifying cloth are overcome. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 8 denotes a bag-shaped humidifying cloth that is stretchable and has air permeability, and a clipper 10 is attached to the open end 9 of the humidifying cloth 8.
The clipper 10 has a drain port 1 to the water tank 11.
2 and the outer periphery of a water tray 14 having a drain pipe 13 in a detachable manner. Further, a vent lily 16 is provided in the center of the water tray 14 so that the air from the blower 15 passes through and is blown out into the humidifying cloth 8.The vent lily 16 absorbs water from the water storage tank 11. do. A water supply hose 17 and a water supply pipe 18 are provided. 19 is a heater provided on the outlet side of the blower 15;
20 is a control box for an electric circuit, 21 is a switch for the heater 20, 22 is a blower operation switch for changing the amount of air blown by the blower 15, and 23 is a casing. 24 indicates water droplets scattered from the ventilate 16.

To explain the operation of the above configuration, when the humidifying operation is stopped, the humidifying cloth 8 is placed on top of the water tray 14 in a folded state as shown in FIG. 1. In such a state, the blower operation switch 22
When turned on, the blowing pressure of the blower 15 causes the second
As shown in the figure, the humidifying cloth 8 is inflated and expanded, and the blown air is passed from the inside to the outside of the entire surface of the humidifying cloth 8. Also at this time,
When the air from the blower 15 passes through the ventilator 16, water in the water tank 11 is sucked through the water supply hose 17 and the water supply pipe 18 due to the suction action of the ventilator 16, and becomes water droplets all over the inner surface of the humidifying cloth 8. The moisture is scattered, and the humidifying cloth 8 becomes impregnated with moisture. Therefore, in such an operating state, air pressure acts uniformly on the expanded and expanded humidifying cloth 8, and air passes from the inside to the outside of the entire surface of the humidifying cloth, so that air is removed from the entire humidifying cloth 8. , the air is humidified.

In addition, by switching the blower operation switch 22,
When the amount of air is increased, the amount of air that passes from the inside of the humidifying cloth 8 to the outside also increases, so that the amount of humidification can be increased. Furthermore, by installing a heater 19 on the outlet side of the blower 15 and blowing out hot air,
The surface of the humidifying cloth 8 is also heated, and the amount of humidification can be increased.

As described above, the effects of this embodiment are as follows: <1> Since the humidifying cloth 8 is expanded and expanded only during humidifying operation, the humidifier becomes extremely compact when the operation is stopped.

<2> Since the function of expanding and expanding the humidifying cloth 8 and the function of scattering moisture inside the humidifying cloth 8 are performed by one blower 15, cost can be reduced.

<3> By switching the amount of air blown by the blower 15, the amount of humidification can be easily adjusted.

<4> By providing the heater 19 and blowing warm air, the amount of humidification can be adjusted.

<5> By removing the clipper 10 from the water tray 14, cleaning and maintenance of the humidifying cloth 8 can be easily performed.

As is clear from the above description, the humidifier of the present invention has the following effects by blowing air from inside to outside of a stretchable and breathable bag-like humidifying cloth impregnated with water.

<1> From the inside of the bag-shaped humidifying cloth to the outside,
Since air is blown, the same air blowing pressure acts uniformly on the entire humidifying cloth, the air blowing resistance is small, and the entire surface of the humidifying cloth acts as a humidifying surface, so the humidifying performance is extremely good.

<2> By using a stretchable, bag-shaped humidifying cloth, even if calcium components contained in water adhere to the inside of the humidifying cloth, it can be easily removed.

<3> Since the humidifying cloth is not immersed in water when the humidifying operation is stopped, the humidifying performance is maintained for a long period of time without the problem of clogging of the humidifying cloth due to water stains, etc.

(4) As a means of wetting the bag-shaped humidifying cloth, a ventilator uses air from an air blower to scatter mist water droplets on the inner surface of the humidifying cloth, so even if the bag-shaped humidifying cloth is made large, It is possible to wet the entire inner surface.
