Water-purifying filter element and water purifier

Abstract

The invention provides a water-purifying filter element and a water purifier equipped with the water-purifying filter element. The water-purifying filter element is capable of restraining the flow of water flowing in the inner side even though under a situation that the water guided from an upper part is discharged from a lower part. A purifying chamber (S2) for purifying water and an additive agent containing chamber (S1) for containing additive agent (16) to be added into the water are formed in the housing (7) of the water-purifying filter element (6), and an air collecting part (27) is positioned at the lower part of an isolation wall (14) positioned at the lower part of the additive agent containing chamber (S1).

Description

technical field [0001] The present invention relates to a water purification filter element and a water purifier provided with the water purification filter element. Background technique [0002] Conventionally, as a water purification cartridge that can be installed in a water purifier, a water purification cartridge is known in which an additive housing for housing an additive (filter material) having a functional active ingredient is formed in a cylindrical case. part, and the bypass flow path bypassing the additive containing part, the raw water is introduced from the lower part of the shell into the additive containing part and the bypass flow path, and the water containing functional active ingredients passing through the additive containing part and the bypass flow path The bypass water passing through the flow path is mixed in the upper space of the housing and discharged from the upper part of the housing (for example, refer to Patent Document 1). [0003] In this ...

Problems solved by technology

[0005] However, in the water purifier, there is also a water purifier using a water purifier of a type that introduces raw water from the top and discharges purified water from the lower end like a tank-type water purifier, and the above-mentioned current situation is applied to the water purifier. In some technical cases, the water flowing in from the upper part may inhibit the upward movement of the air in the water purification filter, and form air accumulation in the lower part of the raw water inlet in the water purification filter.

And, when such air accumulation is formed in the water purification cartridge, the air accumulation may hinder the flow of water flowing in the water purification cartridge, so that the flow rate of water passing through the water purification cartridge becomes unstable.
