Title: WARM WATER RECIRCULATING VALVE USING DIRECT WATER SUPPLY TUBE
Abstract:
The present invention relates to a warm water recirculating valve using a direct water supply tube and, more particularly, to a warm water recirculating valve provided between a warm water supply tube (13) installed in an existing housing and a direct water supply tube (14) in order to recirculate warm water, the warm water recirculating valve comprising: a housing (110) having warm water channels (111, 112) formed therein and connected to the warm water supply tube (13), having direct water channels (114, 115, 116) formed therein and connected to the direct water supply tube (14), and having a recirculating channel (113) formed therein and connected between the warm water channels (111, 112) and the direct water channels (114, 115, 116); and a water pressure plate (140) provided in the direct water channels (114, 115, 116) so as to generate a differential pressure such that, when warm water is recirculated, the recirculating channel (113) is opened by pressure of the recirculated warm water and, when direct water is used, the recirculating channel (113) is closed by pressure of the direct water.
