Abstract

PURPOSE:To obtain a device to which dust or the like does not adhere even in case dry air is blown to a hollow porous member by a method wherein filters are fitted to an air circulation surface of the frame body on the upstream side of air current. CONSTITUTION:The average diameter of numberless minute holes existing in a porous sheets 1 is 10mum or less to pass vapour steam freely, however, not to pass liquid water. The humidification frame body 5, whose inner side is snaked by the hollow porous member having the predetermined intervals each other and holds the snaking shape while it has a filter inserting sections 5a and the air circulating surface 5b. The hollow member and the humidification frame are sealed and fixed by an adhesive joining or a heat welding.

Description

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

[Conventional technology]

A conventional device of this type is shown in FIG.

In the figure, (1) is a hollow porous member made of a hydrophobic polymer made of porous sheet laminated and sealed by adhesive or heat fusion.
) represents the water outlet. Also, in the figure (I) and (B) indicate the direction of air flow.

Next, we will explain the operation. ・Water supplied from the water supply port is supplied into a hollow porous member made of hydrophobic polymer, and the air existing inside is absorbed through the fine pores of the porous sheet. It is filled with water supplied by the drain. When dry air is blown from a blower (not shown) etc., the surface of the hollow porous member is ventilated. At this time, water vapor can freely pass through the fine pores of the porous sheet, so the water in the hollow porous member is evaporates into dry air to obtain humidified air.

[Problem that the invention seeks to solve]

Conventional devices configured in this manner have the disadvantage that when all dry air is blown to perform humidification, dust and the like adhere to the hollow member, causing clogging of the hollow member and reducing the humidifying ability. Ta.

The present invention was made to solve this problem, and an object of the present invention is to provide an apparatus in which dust and the like do not adhere to a hollow porous member even when dry air is blown onto the hollow porous member.

[Means for solving problems]

The humidifier according to the present invention includes a hollow porous member having a water supply port at one end and an air flow surface provided in a frame, and a filter attached to the air flow surface of the frame on the upstream side of the air flow. be.

[Embodiments of the invention]

An embodiment of the present invention will be described below.

FIG. 1 shows a humidifying element structure using a hollow porous member made of a hydrophobic polymer according to the present invention. fi in the figure
+ represents a porous sheet made of hydrophobic polymer,
For example polyethylene.

Polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polycarbonate.

Polyester, fluorocarbon resin, etc. are used as materials. ・The average pore diameter of the countless micropores that exist in the porous sheet allows water vapor (gaseous water molecules) to pass through freely, but liquid water (liquid water molecules) cannot pass through. 10 to prevent it from passing through at all.
It needs to be less than μm. In the figure (5), the hollow porous members are meandered at a predetermined interval from each other as shown in FIG.
The hollow member, which is a humidifying frame having a) and an air circulation surface (5b)', and the humidifier are sealed and fixed by adhesive or heat fusion.

(21 represents a water supply port, t31d discharge port, (41 represents a filter).

〔Effect of the invention〕

As described above, in this invention, when a hollow porous member is supplied with water and humidified, a filter is provided on the frame on the upstream side of the dry air flow, and only the air that has passed through the filter is ventilated to the humidifier. What is the effect that dust and the like do not adhere to the hollow porous member, clogging, etc. do not occur, and the humidification ability does not decrease.

[Brief explanation of drawings]

FIG. 1 is a perspective view of a humidifier showing an embodiment of the present invention, and FIG. 3 is a perspective view of a humidifying element structure. In the figure, Il+ is a porous sheet of a hollow porous member, (2) is a supply port, and (4
) is a filter, and (6) is a humidifying frame. The same reference numerals in the figures indicate the same or corresponding parts.

Claims (1)

[Claims] A humidifying element structure, which has a water supply port at one end and is composed of a hollow porous member made of a hydrophobic polymer, is provided in a frame body having an air circulation surface, and air circulation in the frame body on the upstream side of the air flow. A humidifier, characterized in that a filter is attached to the surface, and the water is supplied from the water supply port into the hollow interior while blowing dry air to the flow surface for humidification.
