Although water is introduced at high pressure, the introduced water can remain in the cold water tank for a period of time required for being cooled, and although water is introduced at high pressure, the introduced water can be in a stable state in the cold water tank. Thus, water can be cooled with its inflow pressure maintained, and the degree of freedom of a faucet or cock for allowing cold water to flow therethrough can be improved in its height.

A temperature regulating method of a humidifier regulates a temperature of water vapor ejected therefrom according to a surrounding temperature. A cool humidification mode is added to a humidification mode of the humidifier, and a temperature of a humidifying tub is detected upon being shifted into the cool humidification mode by a user. Thus, the detected temperature is compared with a temperature preset for performing the cool humidification mode to turn off the heater when the temperature of the humidifying tub is higher than the preset temperature and, turn on the heater otherwise, thereby regulating the temperature of the water vapor ejected from an ejecting slit of the humidifier according to the surrounding temperature thereof.

In a combination type humidifier having a heater and an ultrasonic vibrator, an art for preventing the ultrasonic vibrator from being thermally damaged due to a heat produced by the heater is disclosed. First, a current humidity of a space, a water temperature of a humidifying chamber and a target humidity set by a user are detected. When the current humidity is higher than the target humidity, a fan motor begins to operate for a rapid heat loss. Otherwise, when the target humidity is higher than the current humidity, an error message concerning the setting of the target humidity is displayed and the fan motor is driven for a predetermined time. The heater is controlled so that the water temperature of the humidifying chamber is kept below the limit temperature by using a result of comparing the water temperature of the humidifying chamber with a limit temperature that is set for protecting the ultrasonic vibrator while the ultrasonic vibrator and the heater are simultaneously operated by a user's selection. When a user selects a turbo mode, the turbo mode is changed into a mode in which a quantity of produced vapor is less than in the turbo mode, and then the ultrasonic vibrator is operated.

A method and an apparatus for sensing an illuminance and a temperature around a humidifier and controlling a humidifying operation is disclosed. An illuminance inside a room in which a humidifying operation is applied by the humidifier is sensed by an illuminance sensor. The humidifying operation of the humidifier is operated in a sleeping humidification mode when the sensed illuminance is lower than a reference illuminance. The humidifying operation of the humidifier is operated in a normal humidification mode when the sensed illuminance is higher than the reference illuminance. A temperature inside the room in which the humidifying operation is applied by the humidifier is sensed by a temperature sensor. The humidifier executes a heater humidification and an ultrasonic humidification when the sensed temperature is lower than a reference temperature. The humidifier stops the heater humidification and executes the ultrasonic humidification when the sensed temperature is higher than the reference temperature. Accordingly, the humidifier provides an agreeable humidification environment to the user whether the user is sleeping or is awake.

The appliance for dispensing warm and cold water has a heater for heating water in tank, a PTC heater for preliminarily heating newly supplied water in the tank toward a predetermined temperature, and a comparting member for forming a comparted space around the PTC heater. The comparting member is formed with a plurality of water flow apertures for communicating the comparted space with an inner space of the tank. When warm water in the tank is dispensed to outside, the same amount of water with the dispensed water is supplied in the tank. The newly supplied water is flowed into the inner surface of the tank after being heated by the PTC heater in the comparted space. Accordingly, the fall of temperature of warm water in the tank by the newly supplied water is prevented, and it is possible to dispense warm water having appropriate temperature at any time.
