Description

Easy-to-replace multi-filter assembly The present invention relates to a multi-filter assembly mounted on a water purifier to purify water, and more specifically, to a multi-filter assembly in which individual filters among a plurality of filters mounted on the multi-filter assembly can be easily replaced. Water purifiers use 3 to 5 filters arranged in series or parallel depending on the purpose and location of use. Generally, pleated filters, carbon filters, reverse osmosis filters, hollow fiber filters, post-carbon filters, etc. are selected and placed inside the water purifier. When these multiple filters are arranged in series or parallel with connecting pipes, the volume occupied by the filter unit within the water purifier increases, ultimately leading to a larger size for the water purifier product. To solve this problem, a multi-filter assembly is being developed that mounts multiple filters by partitioning the space within a single filter housing. As related prior art, Patent Document 1 discloses an integrated filter assembly in which an outer carbon filter is placed in a single filter housing and a reverse osmosis filter is placed inside the carbon filter. Although Patent Document 1 can reduce the size of the product by implementing a multi-filter assembly, it does not take into account the replacement cycle of the filters, which are consumables. Generally, the replacement cycle of carbon filters is 12 to 18 months, while the replacement cycle of reverse osmosis filters is 24 to 36 months, which is about twice as long as that of carbon filters. Therefore, in an integrated multi-filter assembly such as Patent Document 1, all other filters must be replaced in accordance with the replacement cycle of the carbon filter. The reverse osmosis filter must be replaced even though there is still sufficient remaining lifespan. This is a waste of resources and ultimately results in a cost burden for the consumer. Therefore, there is a need to develop a new structure that allows for the use of a multi-filter assembly to reduce the volume of water purifier products, while enabling easy replacement of each installed filter without mutual interference. FIG. 1 is an exploded perspective view of a multi-filter assembly according to one embodiment of the present invention. Figure 2 is a drawing showing the combined state of the configuration of Figure 1. FIGS. 3 and 4 are drawings for explaining the detachment of the first filter housing and the second filter housing shown in FIG. 1. Figure 5 is a cross-sectional view of a multi-filter assembly disassembled along the line I-I' shown in Figure 1. Figures 6 and 7 are drawings to show the detachable structure of the connector and UV module shown in Figure 1. Hereinafter, the features of the present invention will be described by citing embodiments through the drawings. However, since the exemplified embodiments, structures, and shapes can be implemented in other embodiments without departing from the technical spirit and scope of the present invention, they should be accepted as encompassing the components of the claims and their equivalent scopes. It should be noted that in assigning reference numbers to the components of each drawing in this specification, identical components are assigned the same number whenever possible, even if they are shown in different drawings. Meanwhile, the meaning of the terms described in this specification should be understood as follows. A singular expression should be understood to include a plural expression unless the context clearly defines otherwise, and terms such as "first," "second," etc., are intended to distinguish one component from another, and the scope of rights shall not be limited by these terms. Terms such as "include" or "have" should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. The term "at least one" should be understood to include all combinations that can be presented from one or more related items. The term "and/or" should be understood to include all combinations that can be presented from one or more related items. When it is stated that one component is "connected or placed" to another component, it should be understood that it may be directly connected or installed to that other component, or that there may be other components in between. On the other hand, when it is stated that one component is "directly connected or installed" to another component, it should be understood that there are no other components in between. Meanwhile, other expressions describing the relationship between components, such as "between" and "exactly between," or "adjacent to" and "directly adjacent to," should be interpreted in the same way.
