KR970032953A - Water temperature selective water purifier and its control method - Google Patents

Abstract

The present invention relates to a water temperature selective water purifier and a control method for controlling the discharge amount of cold water and the discharge amount of hot water so as to discharge the temperature of the water discharged from the water purifier to a temperature set by a user.

In the related art, since the setting and control means of the water supply temperature were not provided, the user had to arbitrarily mix cold water and hot water, and thus it was not only difficult to control the temperature, but also inconvenient to use.

The present invention provides a water purifier configured to heat or cool water in a water reservoir as a heater and a cooler controlled by a microprocessor, the water temperature setting means for setting the temperature of water to be supplied, and the temperature of hot and cold water And a hot water valve and a cold water valve for controlling hot water temperature sensing means and a cold water temperature sensing means for sensing, a discharge valve for hot and cold water, and a hot water valve and a cold water valve according to the hot and cold water temperatures and the set water temperature. The invention consists of a microprocessor that calculates and controls the opening amount of the hot water valve and the cold water valve according to the temperature of hot and cold water and the set water temperature.
