Provided is a mixer faucet that can suppress the occurrence of water leakage. A mixer faucet includes: a fixed valve body including a hot water supply hole, a cold water supply hole, and a drain hole; a movable valve body that includes a flow path forming recess and is configured to slide on the fixed valve body; and a handle configured to control the movable valve body. The fixed valve body includes a collection groove that is not connected to either the hot water supply hole or the cold water supply hole and is connected only to the drain hole. The collection groove can capture water leaking from the hot water supply hole, the cold water supply hole, or the drain hole. The captured water can flow into the drain hole through the collection groove.

The present invention provides a method for controlling a drinking-water supply device, the method comprising: a first step of connecting a guide pipe of a case separable from a cabinet to form a channel through which water moves from the case to the cabinet; a second step of supplying the cabinet with sterile water electrolyzed by an electrolytic module included in the case; and a third step of supplying the cabinet with water which has not passed through the electrolytic module included in the case, wherein the sterilization water and the water are supplied to the cabinet from the case via the guide pipe in the second step and the third step.

The present inventive concept relates to a method for adjusting a water temperature in a water recirculating device. The method comprises determining a first parameter associated with a first water path; determining a second parameter associated with a second water path; determining a setting of a mixing valve arrangement based on the first and second parameter; and adjusting a water temperature of water output by a water outlet based on the setting of the mixing valve arrangement. The invention also relates to a water recirculating device configured to adjust a water temperature of water output by a water outlet based on the setting of the mixing valve arrangement.

Disclosed herein is a water purifier including a coolant tank configured to store coolant, a partitioning plate configured to partition an internal space of the coolant tank into an upper space and a lower space and having a grid rib formed therein to enable coolant of the upper space and coolant of the lower space to circulate, a cold water pipe disposed in the lower space, an evaporator disposed in the upper space, and an agitator disposed inside the coolant tank, wherein the partitioning plate includes an outer water flow guide sleeve extending downwardly from a bottom surface thereof.

Disclosed herein is a water purifier, in which a partitioning container is detachably mounted on the bottom surface of a tank cover, and an agitator is inserted into the partitioning container to be connected to an agitating motor mounted in the tank cover in a state where the partitioning container is mounted on the bottom surface of the tank cover. By this structure, the inner diameter of the partitioning container may be less than the outer diameter of the blade of the agitator.

In an immediate hot water supply operation mode in which a circulation pump is activated while a hot water supply faucet is closed, a water heating apparatus forms an immediate hot water supply circulation path by an inner path including a water entry path, a heat exchanger, and a hot water output path and an outer path bypassing the hot water supply faucet, as being combined. A controller stores as an actual flow rate value for each immediate hot water supply operation mode, a flow rate detection value by a flow rate sensor at predetermined timing, and calculates a flow rate learning value based on a plurality of stored actual flow rate values. When the flow rate detection value becomes larger than a criterion value set in accordance with the flow rate learning value, use of the hot water supply faucet is detected and the circulation pump is deactivated.

A sink system includes a sink basin and a discharge conduit coupled to the sink basin, which is positioned to expel fluid into the sink basin via an outlet thereof. The flow of fluid through the discharge conduit may be activated via a motion sensor or switch coupled directly to the basin or a spacer ring positioned between the basin and a countertop. Controls for adjusting the temperature and/or flow rate of fluid through the discharge conduit may also be coupled to the basin or a spacer ring positioned between the basin and the countertop, or alternatively, to a surface of the countertop. Methods of making and using sink systems are also provided.
