    摘要： According to one embodiment of the present invention, a water purifier can comprise: a filter unit for generating purified water by filtering influent water; a TDS measurement unit provided on the front end of the filter unit so as to measure the TDS of water flowing into the filter unit; a first flow rate measurement unit provided on the front end of the filter unit so as to measure the flow rate of the water flowing into the filter unit; a second flow rate measurement unit provided on the rear end of the filter unit so as to measure the flow rate of the purified water discharged from the filter unit; a concentrated water flow rate adjustment valve for adjusting the flow rate of concentrated water discharged from the filter unit; and a control unit for controlling an opening degree of the concentrated water flow rate adjustment valve on the basis of a measurement value received from at least one of the TDS measurement unit, the first flow rate measurement unit, and the second flow rate measurement unit.

    摘要： A latch valve comprises an inflow path (110) and an outflow path (116) formed in a housing (127); a solenoid (SL) having a coil wound thereon; a permanent magnet (M) positioned at an upper portion of a plunger (112) and latching the plunger (122) when the plunger (122) is lifted; a spring (125) positioned between the permanent magnet (M) and the plunger (122); a support body (121) having an inlet (111) connected to the inflow path (110) and an outlet (114) connected to the outflow path (116); and a diaphragm (120) having the support body (121) inserted therein. The plunger (122) is lifted or lowered by a magnetic force induced by the coil to open and close the outlet (114). An additional outflow path (117) constantly communicating with a space part (130) formed in the housing (127) between the support body (121) and the plunger (122) is provided to allow a flow to be generated in the additional outflow path (117) even when the plunger (122) is closed. The additional outflow path (117) is formed in the housing (127) surrounding the plunger (122). A stopper (132) is formed in the space part (130) of the latch valve in order to prevent the support body (121) from lifting by more than a certain degree.

    摘要： There is provided an air purifier having a dehumidification function, including: a body case having an inner space; a blower part installed in the inner space of the body case and drawing outside air from both sides of the body case through a single blower fan; an air purifying part purifying air drawn from one side of the body case; and a dehumidifying part removing moisture from air drawn from the other side of the body case by a dehumidifying rotor. Through the blower part drawing the air from both sides of the body case, the air purifier purifies the air drawn from one side of the body case and dehumidifies the air drawn from the other side of the body case. Accordingly, a drop in an airflow amount caused by concurrently performing the dehumidification and the purification may be alleviated, so improved dehumidification and purification effects are achieved.
