Embodiment

[0070] Refer below Figure 1 to Figure 11 , the water purification filter according to the embodiment of the present invention will be described. In this embodiment, for example, a case of a kettle-type water purifier will be described by taking a water purifier using a water purifying cartridge as an example. But not limited thereto, the water purification filter element of the present invention can be applied to various water purifiers. In the following description, "upper (upper part / above)" means the upper part (upper part / above) of a vertical direction when a water purifier is installed on a horizontal surface. In addition, "down (lower part / below)" means below (lower part / below) in a vertical direction when a water purifier is installed on a horizontal surface.

Abstract

The invention provides a water purification filter core capable of truly enabling air to flow out to the exterior from space for accommodating multiple hollow fiber membranes. In the water purification filter core (100), pipes (160), extending in up-down directions, are arranged in first space (S1). The pipes (160) are communicated from the interior of second space (S2) to the outside of a top plate (120) at the upper portion of a housing (110) so that an air path, enabling air in the second space (S2) to flow out to the exterior of the housing (110), is formed. Furthermore, a separation part (117) is provided with a protruding portion (117b) protruding towards the interior of the second space (S2). The protruding portion (117b) helps to ensure that the air path is located at the gaps among an inlet (E) at the side of the second space (S2) and the hollow fiber membranes (180) by inhibiting the hollow fiber membranes (180) from moving towards the side of the first space (S1).

Description

technical field [0001] The invention relates to a water purification filter element which can be freely assembled and disassembled on the main body of a water purifier. Background technique [0002] In the prior art, there is known a water purification filter element which can be freely assembled and disassembled on the main body of the water purifier, which accommodates a plurality of activated carbon or ion exchange resin membranes, and a plurality of hollow fiber membranes. [0003] In a water purification cartridge having a plurality of hollow fiber membranes, there is a problem that the flow rate decreases due to air bubbles remaining on the surface of the hollow fiber membranes. In order to solve this problem, a technique is known in which hydrophobic fibers are arranged in a hollow fiber membrane bundle so that air flows out (see Patent Document 1). However, when this technique is used, costs increase due to the deployment of hydrophobic fibers. In addition, there i...
