Problems solved by technology

[0005] However, the related art head has a complicated structure so that the flow path can be opened and closed by the flow path switching plunger, which is supported by the elastic member when attaching and detaching the filter.
Therefore, there are problems of poor productivity and assembly workability
[0006] In addition, there is a problem that, due to the structure of the slid flow path switching plunger, the bypass path of the flow path is complicated, whereby the flow performance of water deteriorates
[0007] In addition, there may arise a problem that the flow path cannot be switched when the performance of the elastic member is deteriorated or the elastic member is abnormal

Abstract

The invention discloses a filter structure and a water purifying apparatus. The filter structure comprises: a housing body formed in a cylindrical shape to have a first accommodating space and having an upper opening portion; a housing cap coupled to the upper opening portion of the housing body by a portion thereof being formed in a cylindrical shape to have a second accommodating space, wherein a coupling projection and an upper opening portion are formed on an outer circumferential surface thereof, and a housing fastening portion is formed on an inner circumferential surface thereof; a filtering member having a cylindrical shape accommodated in the first accommodating space; and an upper supporter coupled to an upper portion of the filtering member and an inner surface of the housing cap respectively, and accommodated in the second accommodating space.

Description

Background technique [0001] Generally, a water purification apparatus is used to purify supply water using a filter or filter material, and includes an apparatus for purifying water from a water pipe or a water tank to make it drinkable. [0002] A water purifier is a representative example of water purification equipment that supplies potable water. Recently, the whole or a part of such a water purification apparatus has been provided even in a refrigerator to supply purified water through the refrigerator or to make ice using the purified water. [0003] In a refrigerator including a water purification device, it is required to replace or inspect a filter constituting the water purification device when necessary. Correspondingly, the filter is detachably mounted for this purpose. The water purification apparatus is configured to have a bypass flow path capable of supplying water even in a state where the filter is detached, and then the user can still take out the water ev...
