- the present invention relates to a water purifier equipped with a complex filter capable of implementing additional functions using a member.
- a water purifier is a device that filters obtained raw water into purified water that a user can drink and provides to the user. These water purifiers are used by combining several filters for raw water filtration. When each filter is used in combination, the internal layout of the water purifier becomes complicated and the volume occupied by the filter inside increases, so that the entire water purifier There was a problem with the increase in volume. Therefore, in order to solve this problem, a composite filter in which each filter is integrated is sometimes used.
- the water purifier disclosed in Korean Patent Publication No. 2021-0040502 of Coway Co., Ltd. is provided with a composite filter for filtering raw water.
- the composite filter includes a first filter material and a second filter material, and each filter material is a single filter element, for example, a sediment filter, a pre-carbon filter, a post-carbon filter, an antibacterial filter, various functional filters, etc. It can be selected from known filter materials.
- a complex filter has only a flow path through which raw water, primary and secondary purified water flows, and does not have an external processing member that additionally processes the first purified water from the outside, implementation of additional functions using the external processing member. This is limited, and there is a problem that the reverse osmosis filter cannot be used as a composite filter by integrating the reverse osmosis filter because there is no flow path through which the concentrated living water discharged through the reverse osmosis filter flows.
- Korean Patent Publication No. 2019-0060390 of Alcamedi Co., Ltd. discloses a conventional composite filter.
- a carbon filter, a nano filter, and a calcium filter are integrally mounted on the upper cap, and the obtained raw water is filtered while sequentially passing through these filters.
- a composite filter is configured to enable only sequential water treatment between internal filters, there is a problem in that the implementation of additional functions using an external treatment member is limited in the process of raw water passing through the composite filter.
- a composite filter for a water purifier disclosed in Korean Patent Publication No. 2003-0096867 of Woongjin Coway Co., Ltd. includes a composite filter for filtering raw water.
- the compound filter has a segment filter on the outside, and on the inside, a first filter unit in which an ACF filter is overlapped, a second filter unit in which a plate-shaped ACF filter is disposed, and a third filter unit in which an AC filter and a UF filter are disposed.
- a filter unit is provided.
- the composite filter is manufactured, the composite filter is manufactured by sequentially stacking the first to third filter units inside the housing and then fusing the cap.

- the water purifier equipped with a composite filter is capable of discharging raw water, second purified water, externally treated water, and third purified water, as well as discharge of living water.
- the composite filter it is possible to implement additional functions using an external treatment member, and by integrating three internal filter members including a spiral wound internal filter member to form a composite filter, it is easy to downsize and replace the water purifier, so that the user can Convenience is improved, and each filter is modularized through a first module provided with a pre-treatment internal filter member and a spiral wound internal filter member and a second module equipped with a post-treatment internal filter member, and the first module and the second module are provided.
- the composite filter is configured by stacking and arranging two modules, manufacturability is improved, and a discharge tube member is disposed through the center of the first module so that the third purified water generated from the second module disposed below is discharged to the outside. As a result, the third purified water is not mixed with the second purified water, so that the operation stability of the water purifier can be secured.
- the head member of the housing unit has an independent independent water source in which raw water, second purified water, external treated water, third purified water, and living water are not mixed. Since the first to fourth partition walls are provided to form a flow path, tubes through which raw water, second purified water, external treated water, third purified water, and domestic water flow are concentrated on the upper part of the composite filter to improve the layout design freedom of other parts. The purpose.
- a spiral-wound inner filter member is spirally wound around the central tube, and the second purified water flows into the second purified water passage provided therein.
- 2 Purified water through-holes are formed, and the discharge tube member inserted through the center of the central tube is spaced apart from the central tube at a certain distance to maintain the second purified water flow path stably and improve operational reliability through the smooth flow of the second purified water.
- the water purifier equipped with a composite filter effectively prevents the third purified water from being mixed with the second purified water as the fourth partition wall extends in the axial direction along the discharge tube member. Its purpose is to improve the operation stability of
- the third partition wall is disposed to extend in the axial direction along the central tube, effectively preventing the second purified water discharged from being mixed with the discharged domestic water, thereby operating the water purifier. It aims to improve stability.
- the water purifier equipped with a composite filter according to an embodiment of the present invention is disposed such that the second partition wall extends in the axial direction along the first upward guide, effectively preventing the raw water obtained from being mixed with the discharged domestic water, thereby operating the water purifier. It aims to improve stability.
- the internal pretreatment filter member may be fixed by disposing the first upper cap member and the first lower cap member on the upper and lower portions of the internal pretreatment filter member, respectively.
- the inner guide supports the inner surface of the pretreatment inner filter member, and the first purified water is passed through the first purified water penetration hole formed in the inner guide. Its purpose is to improve the operational stability of the water purifier while flowing smoothly.
- An object of the water purifier having a composite filter according to an embodiment of the present invention is to improve the structural stability of the first module by arranging an inner guide to connect the first upper cap member and the first lower cap member.
- the inner guide is spaced apart from the outer surface of the spiral wound inner filter member, a first purified water flow path through which the first purified water flows is stably formed between them. Since the purified water flow path extends to the lower portion of the spiral wound internal filter member, the first purified water that has moved inside through the first purified water through hole formed in the internal guide moves stably to the lower portion of the spiral wound internal filter member, thereby improving the operational stability of the water purifier. aimed at enhancing
- the second upper cap member is spaced apart from the first upper cap member, so that a raw water flow path is stably formed to ensure a smooth flow of raw water obtained.
- the second downward support guide is extended to the first lower cap member, the raw water received into the first module is prevented from being mixed with the external treated water received while flowing out of the first module, thereby preventing the external treated water and the first 3
