Abstract

A filter coupling module to which a filter unit is attached includes a frame portion and a fastening portion. The frame portion forms a storage space in which a filter unit is housed. The fastening portion includes a fixing unit coupled to the upper part of the frame portion and a rotating unit coupled to the interior of the fixing unit. At this time, while the lower projection of the filter unit is fixed to the frame portion, the fixing unit and the rotating unit rotate relative to each other, causing the fastening portion to move downward and be coupled to the upper projection of the filter unit.

Description

Filter fastening module for attaching and detaching a filter unit The present invention relates to a filter coupling module to which a filter unit is detachably attached, and more specifically, to a filter coupling module used to detachably attach a filter unit for a water purifier to the interior of the water purifier, and which is located inside the water purifier to which the filter unit is detachably attached. The filter unit for the water purifier must be replaced after a certain period of use, and for this replacement work, a filter coupling module to which the filter unit is attached and detached is provided inside the water purifier. Accordingly, various technologies for attaching and detaching the above filter unit to the above filter coupling module are being developed. For example, Korean Registered Patent No. 10-2332063 discloses a technology for rotating the filter unit to connect it to the filter coupling module, and Korean Registered Patent No. 10-2150564 discloses a technology in which the upper part of the filter unit is connected to the filter coupling module and mounted on a water purifier. However, in the case of conventional rotary coupling structures or structures where only the upper part of the filter unit is coupled and mounted as described above, the workability during the attachment and detachment of the filter unit is not high, resulting in a significant amount of time; furthermore, if unstable fixation is caused by the operator's lack of skill or carelessness, problems such as leakage may occur. In particular, in the case of a filter unit having a structure with protrusions (nipples) formed on the upper and lower parts, damage to the protrusions may occur frequently during the operation process, and workability is particularly degraded when the structure of the filter coupling module is complex. Furthermore, the use of non-standardized filter units also causes damage to the filter coupling module or issues regarding maintenance.
