Abstract

PURPOSE:To prevent humidifying characteristic from being decreased even if a humidifying operation is carried out for a long period of time by a method wherein a water supplying pipe is arranged at an end part of a bag-like sheet and a water discharging pipe is arranged at the other end of the sheet, the water discharging pipe is engaged to be slightly lower than a water level in a water tank, an extremity end thereof is made in an inverted U-shape in such a way as it is guided into a drain pan in an air conditioner and the like. CONSTITUTION:Water having a high degree of impurities in a humidifying element 40 is passed through a water discharging pipe 6 and gradually discharged into a drain pan 11. At this time, an amount of water discharged through a discharging pipe 6 is made to a minimum value by slightly lowering a height of an inverted U-shaped pipe 6a than a water level H of a water tank 7 toward the minimum amount of water not decreasing the humidifying performance, whereby a useless amount of discharged water is made minimum, impurities contained in the supplied water and the like are discharged and then a humidifier not decreasing the humidifying performance is attained. In turn, in case that some impurities are adhered within the humidifying element 40, the inverted U-shaped pipe 6a is lowered downwardly to increase the amount of discharged water and to cause the water to be discharged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a humidifier used for air conditioning.

[Conventional technology]

FIG. 2 shows a conventional humidifying device shown in, for example, Japanese Utility Model Publication No. 511-50841, in which one of the two hydrophobic porous sheets (+11 and 121) is
It is formed by bending a large number of thin-walled fins 131 arranged in parallel at equal pitches, and the porous sheet 12H
- is placed on the flat surface of the porous sheet 111VC opposite to the fin (3:) and the porous sheet [11kWA is rotated and polymerized, and the periphery thereof is joined in a sealed manner with an adhesive or the like, It is formed in the closed chamber 1411.The water supply pipe (6) is connected to the closed chamber (4) and introduces a predetermined humidifying water into the closed chamber (41).

Next, the operation will be explained. First, water tank (not shown)
Water is supplied into the sealed chamber (4) through the water supply pipe 161 and is held therein. By blowing dry air from the direction of arrow (a) into the space around the sealed chamber 141, a hydrophobic porous sheet is created that does not allow water to pass through but only allows water vapor to pass through.
, +21 is contained in the air, and the humidified air exits in the direction of arrow (b), thereby performing humidification.

[Problem that the invention seeks to solve]

When a conventional humidifier configured as described above is operated for a long period of time, impurities contained in the supplied water remain inside the closed chamber (41), which significantly reduces the humidifying performance. There was a problem.

This invention was made to solve the above-mentioned problems, and an object thereof is to provide a humidifier whose humidifying performance does not decrease even after long-term humidifying operation.

[Means for solving problems]

The humidifier according to the present invention is configured such that a hydrophobic porous sheet is formed into a hollow bag band shape, water is allowed to flow into the inside of the sheet, and air to be humidified is fused onto the outer surface of the humidifier. A water supply pipe is installed at one end of the sheet, and a water drain pipe is provided at the end of the pond, and the drain pipe is hung so that it is slightly lower than the water level of the water tank, and the tip is placed in the drain pan of an air conditioner, etc. It is structured in an inverted U shape so as to lead the way.

[Effect]

The humidifier of the present invention removes water impurities remaining inside the bag-shaped hydrophobic porous sheet and prevents a decrease in humidification performance q by constantly discharging a small amount of water from the drain pipe.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention NJ' will be explained based on the drawings. Is Figure 1 an example of this invention? It is a block diagram of the humidifier shown in FIG.

In the figure, ■ is a humidifying element made of a hydrophobic porous sheet in the shape of a hollow bag, and has a water supply pipe 151 at both ends and a flexible drain pipe 161 made of, for example, a vinyl tube.
is connected. 17: Humidifying element 141. This water tank is located higher up and supplies water, and is connected to the water supply pipe (6). (8) and (9) are solenoid valves that control the water supply from the water supply to the water tank (71). , and the float switch, (6a) is the inverted U-shaped part %111 of the drain pipe 161.
1.Water discharged through the i-drain pipe (6) and inverted U-shaped pipe section (6a)? This is a drain plate (11) for receiving the drain.

In addition, the humidifying element (7) is a space (ventilation path) that serves as a passage for dry air. Open, fold, and stack multiple layers to get the overall shape? ′
It is formed in the shape of a rectangular parallelepiped, and although it has a small volume, it greatly increases the area for water evaporation. Although not shown in the figure, in order to maintain the shape of the humidifying element @1, the space VC between the stacked humidifying elements is reinforced by inserting a corrugated spacer, such as one made of plastic. ing.

In the zero-force humidifier configured as described above, water inside the humidifying element (G) is evaporated by blowing warm air, etc. from the direction of the arrow (A) so as to bring it into contact with the humidifying element (G). The humidified air leaves in the direction of the arrow (b). When the water inside the humidifying element (G) evaporates and performs humidification, the water level in the water tank 1γ) gradually decreases, and when the water level drops to Al, the float switch 19 closes and the solenoid valve (8) is opened and water is supplied into the water tank (71). When the water level of the water tank 17 rises to the water surface level 1B+, the float switch (91
is opened, the solenoid valve (8) is closed, and water supply to the water tank 17) is stopped. When humidifying in this way, the concentration of impurities in the water inside the humidifying element increases, so this concentrated water is passed through the drain pipe (6) and gradually drained into the drain pan tllll. Is the height of the inverted U-shaped tube part (6a) l to the minimum wax that does not reduce the humidification performance? By making it slightly lower, a humidifier can be obtained in which the amount of wasted water is minimized, impurities contained in the supplied water, etc. are discharged, and the humidification performance is not reduced. If impurities should adhere to the inside of the humidifying element (2), the inverted U-shaped tube section (6a) is lowered to increase the amount of water tt and discharge it to the outside.

〔Effect of the invention〕

As described above, according to the present invention, the drain pipe provided on the drain side of a humidifying element using a hydrophobic porous sheet is formed into an inverted U shape and raised to an extent slightly lower than the water level of the water tank. How much water is wasted due to the installation? A humidifier can be obtained in which all impurities contained in supplied water, etc. are discharged to a minimum, and humidification performance is not reduced.
