Abstract

A water purifier is provided that can automatically shut off the raw water supply when a filter is separated. The water purifier comprises: a filter unit having at least one filter for filtering incoming water; a frame having a filter mounting unit on which the at least one filter is mounted; a supply valve installed on the rear of the frame and opened and closed to supply water to the filter unit; and a water supply operating member installed on the front of the frame and rotatably connected to the supply valve to open and close the supply valve. The water supply operating member rotates between a first position that hinders the separation of the at least one filter and a second position in which the at least one filter can be separated. The water supply operating member can open the supply valve at the first position to supply water to the filter unit, and close the supply valve at the second position to cut off the water supply to the filter unit.

Description

Water Purifier The present invention relates to a water purifier that produces purified water by filtering raw water, and more specifically, to a water purifier in which the raw water can be easily shut off when the filter is replaced or removed. A water purifier is a device that filters incoming water (raw water) to produce purified water and provides it to the user. The filters equipped in water purifiers need to be replaced with new ones because their performance deteriorates after filtering a certain amount of water or after a certain period of time. To replace or remove the filter, the raw water supply to the filter must first be shut off. However, since the water shut-off valve capable of shutting off the raw water is located on the rear of the water purifier, there is a problem in that shutting off the raw water is not easy when the rear of the water purifier is installed adjacent to a wall. In particular, since the water supply shut-off valve is located at the back of the water purifier and is not easily visible, there was a problem where a large amount of raw water was sprayed out due to strong water pressure from the part where the filter was removed when the water purifier user or manager forgot to shut off the raw water and replaced or removed the filter. To solve these problems, the applicant has applied a method in which the supply of raw water is automatically cut off when the first filter is separated by applying a spring-type raw water shut-off fitting structure to the first filter among a plurality of filters provided in the filter section, based on the flow of raw water. However, since this raw water shut-off fitting structure is installed only on the first filter, problems repeatedly occurred where the filter detached from the mounting area due to the raw water pressure and the raw water erupted when a water purifier user or manager removed a filter other than the first one. In particular, because the detached filter travels a considerable distance due to the water pressure, it took a long time to reattach it, posing an inherent risk of product liability (PL) accidents where a large amount of raw water continued to erupt during that period. (In this case, although the raw water can be shut off by removing the first filter equipped with the raw water shut-off fitting structure, there were numerous instances where not only general users unfamiliar with the principle of the raw water shut-off but also water purifier managers panicked and failed to take prompt action to shut off the water.)
