Abstract

PURPOSE:To eliminate deposited impurities easily in simple structure and prevent the performance degradation by installing a water supply filter made of the same material as a humidification element into a water tank and supplying filtered water to the humidification element. CONSTITUTION:A plurality of plate-like humidification elements 5 made of a porous material having water absorbing properties are laid out in an air flow passage where its end section 3a is placed into contact with humidification water 5 in a water supply tank 4. A water supply filter 2 made of the same raw material having water absorbing properties as the humidification elements 3 and water level gauges 11a and 11b are laid out in the water supply tank 4. When humidification is necessary, a water supply solenoid valve 9 is opened so as to supply water into a water receiving tank 2. When the water level reaches a specified water level 8a, the water level gauge 11a detects and the water supply solenoid valve 9 is closed. Then, the supply water passes through the water supply filter 2 which eliminates the impurities contained in the supply water and enters the water supply tank 4 where the water is absorbed by means of the humidification elements 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural evaporative humidifier used for comfort control of air conditioning.

[0002]

2. Description of the Related Art FIG. 6 is a cross-sectional view showing a humidifying portion of this kind described in Japanese Patent Application No. 1-260747. Reference numeral 3 in FIG. 6 is a plurality of substantially L-shaped water-absorbing porous materials. Flat plate with one end 3a
Is in contact with the humidifying water 5 in the water supply tank 4. Reference numeral 6 is a drain pan for receiving water coming out from the other end 3b of the flat plate 3.

The air 7 blown into the humidifier is heated (heating operation) by an air conditioner and has a low relative humidity. Humidification water 5 is stored in the water supply tank 4, and one end portion 3a of the flat plate 3 is in contact with the humidification water 5 so that the flat plate 3 absorbs the water. When the heated air 7 comes into contact with the flat plate 3 that has absorbed the water, the water is naturally evaporated from the flat plate 3 to humidify the air, while the water that cannot be completely evaporated is dropped from the other end 3b of the flat plate. It flows down to the drain pan 6 and is discharged.

[0004]

In this type of system, the supply water is sucked up by utilizing the capillarity, and after sucking, the water is flowed down by the siphon principle.

In order to secure the amount of humidification, it is necessary to keep the element completely wet.

Since the element absorbs the feed water by utilizing the capillary phenomenon, its pore diameter is small, and if the impurities contained in the feed water are large, the element closes the pores and the feed water cannot be sucked up. Further, if it is contained in a large amount even if small, it may accumulate as a residue in the element, hinder sufficient water supply to the element, and lead to a decrease in the amount of humidification.

An object of the present invention is to provide a humidifier capable of removing impurities accumulated in the element with a simple structure and preventing deterioration of performance.

[0008]

In order to achieve the above object, the present invention provides a water supply filter formed of the same material as a humidification element in a water supply tank, and water supplied is passed through a water supply filter and then humidified. The element is supplied.

[0009]

By using the same material as the humidification element for the water supply filter, the pore size is the same, so impurities passing through the water supply filter rarely accumulate in the humidification element, and impurities accumulated in the humidification element. Remains in the feedwater filter and does not affect the humidification element.

Therefore, it is possible to prevent the life of the humidifying element from being shortened.

On the other hand, a large amount of impurities may accumulate in the water supply filter, which may make it difficult to supply water to the humidifying element. Therefore, regular maintenance is required, but compared with the maintenance of all the humidifying elements. It has the advantage that it can be done easily.

[0012]

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

FIG. 1 is a sectional view showing a first embodiment of the present invention,
FIG. 2 is a perspective view showing the shape of the water supply filter of the embodiment of FIG.

In FIG. 1, reference numeral 3 is a flat plate-like humidifying element made of a plurality of water-absorbing porous materials arranged in an air passage, which are arranged in parallel with each other, and one end portion 3 a of the water supply tank 4 is provided. It is in contact with the humidifying water 5. Further, in the water supply tank 4, there are a water supply filter 2 made of a water-absorbing porous material which is the same material as the humidifying element, and water level sensors 11a and 11b. Reference numeral 9 is a solenoid valve for water supply, 10 is a water supply port, and 1 is a storage frame for fixing the upper part of the humidification element 3.

When humidification is required, the water supply solenoid valve 9 is opened. Then, the water passes through the water supply port 10 and is supplied into the water receiving tank 2. When it reaches the water level 8a, the water level sensor 11a detects it and closes the water supply solenoid valve 9 to stop the water supply.

The water supply filter 2 is made of a water-absorbing porous material which is the same material as the humidifying element, and is formed in a box shape as shown in FIG. The water 5 in the water supply filter 2 passes from the front, rear, left and right lower surfaces of the water receiving tank 2 like 5a, 5b, 5c, 5d, 5e. At this time, the impurities contained in the water 5 are
If the pore size of the water supply filter 2 is larger than the pore size, it does not pass through the water receiving tank, but only if it is smaller than the pore size.

The water sucked up from the one end 3a of the humidifying element is partially vaporized into the air 7 and partly discharged from the other end 3b.

At this time, since the impurities contained in the water 5 have passed through the water supply filter 2 of the same material, the impurities are smaller than the pore diameter of the element and rarely remain in the humidifying element, and the other end 3b. More discharged with water.

FIG. 3 is a top view of the humidifying part of the second embodiment of the present invention, and FIG. 4 is a cross sectional view thereof. Figure 5
[Fig. 4] is a perspective view of a water supply filter 2 of a third embodiment.

In FIG. 3, the water supply filter 2 is formed in a flat plate shape, and is inserted into the grooves provided inside both sides of the water supply tank 4. The water 5 supplied from the water supply port 10 passes through the water supply filter 2 and is supplied to the humidification element 3, so that the same state as in the first embodiment will be obtained.

Further, in the second embodiment, the water supply filter 2 is formed in a flat plate shape, but as shown in FIG. 5, the same state can be obtained even if it is folded in a W shape. In this case, in particular, it should be folded in a W shape. As a result, the area of the water supply filter is increased, and the life of the water supply filter 2 itself can be lengthened.

[0022]

According to the present invention, impurities are less likely to be accumulated in the humidifying element, and the deterioration of performance can be prevented.

The humidifying element has a long life and is economical.

Since the water supply filter is simply inserted, serviceability is better than replacement of the humidifying element.

There is an effect.
