The invention discloses a water dispenser realizing automatic heating and automatic water supplementing based on control of a controller. The water dispenser comprises a
water storage tank, a control module, a heating device, a
pressure sensor, a temperature sensor, a communication module and a terminal device, wherein the control module is electrically connected with the heating device; the heating device is used for heating pure water in the
water storage tank; the control module is connected with the communication module and an
alarm device; a control panel is used for controlling the on / off operation of the
system. By means of mutual cooperation of the control module, the sensors, a
data acquisition module, the communication module and the terminal device, the automatic
water supply is realized, through the one-key operation of the control panel, the water amount information of the
water storage tank of the water dispenser is monitored in real time, water is added in advance, and the water purification device has the advantages of being convenient to manage, and being simple and practical; by arranging the heating device and the control module which are matched with each other, the automatic heating for the pure water is realized, a worker sets the
water temperature and controls the heating process through the terminal device, the
water temperature information can be known in real time, and thus a good office environment is provided for the worker.
