CIRCULATION TYPE WATER PURIFIER
First Claim
1. A circulation type water purifier comprising:
- a clean water filter 100;
a storage tank 200 in which water purified through the clean water filter 100 is stored;
a cold/hot water supply tank 300 cooling and heating the water supplied from the storage tank 200 to drain the cooled and heated water to respective drain outlets;

Abstract
There is provided a circulation type water purifier which maximally prevents production of bacteria and microbes by periodically circulating water in the water purifier, and improves lifetime and power saving of a pump by varying the number of circulation times depending on an amount of water used. The circulation type water purifier includes a clean water filter; a storage tank in which water purified through the clean water filter is stored; a cold/hot water supply tank cooling and heating the water supplied from the storage tank to drain the cooled and heated water to respective drain outlets; a drain pipe 351 connected to the cold/hot water supply tank to drain the water in the cold/hot water supply tank when cleansing the interior of the cold/hot water supply tank; a pump 400 periodically circulating water at every circulation time under a control of a microcomputer; a circulation pipe connecting the clean water filter, the cold/hot water supply tank, the drain pipe and the pump, the circulation pipe including a first circulation pipe connecting the clean water filter and the storage tank, a first auxiliary circulation pipe connecting the storage tank and the cold/hot water supply tank, a second circulation pipe connecting the storage tank and the clean water filter, and a second auxiliary circulation pipe connecting the cold/hot water supply tank and the second circulation pipe! and a sterilizer installed to the circulation pipe to sterilize water flowed into the circulation pipe.
