Water temperature control method for water dispenser and water dispenser

Abstract

The invention discloses a water temperature control method for a water dispenser and the water dispenser. The water dispenser comprises a water pump and a heating piece, the heating piece is providedwith a first power section and a second power section, and the power of the first power section is smaller than that of the second power section. The method comprises the steps: collecting the first rotating speed of a water pump needed for heating water to a first standard temperature through a first power section, and collecting the second rotating speed of the water pump needed for heating water to a second standard temperature through a second power section, wherein the first standard temperatures and the second standard temperatures are different from one another; setting a preset water outlet temperature; judging whether the preset water outlet temperature belongs to a first standard temperature or not; if so, starting a first power section and controlling the rotating speed of a water pump to be a corresponding first rotating speed; otherwise, starting the second power section and controlling the rotating speed of the water pump to be the corresponding second rotating speed. According to the water temperature control method for the water dispenser, the cost can be reduced, full-range coverage of the outlet water temperature is achieved, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of water dispensers, in particular to a water temperature control method for a water dispenser and a water dispenser based on the water temperature control method for a water dispenser. Background technique [0002] Water dispensers in the related art generally realize temperature control in three ways, the first is to control the power output of the heating tube, the second is to control the flow output of the water pump, and the third is to simultaneously control the power output of the heating tube and the water pump. flow output. Since the power output of the heat pipe is basically linearly related to the temperature, it is easy to achieve precise temperature control. [0003] However, the cost of the existing control method for the power output of the heat pipe is too high; moreover, since the flow output of the water pump and the temperature are in a non-linear relationship, the control accuracy is ve...

Problems solved by technology

[0003] However, the cost of the existing control method for the power output of the heat pipe is too high; and, because the flow output of the water pump and the temperature are in a non-linear relationship, the control accuracy is very low, so it is difficult to achieve precise temperature control, and The time delay is large, and it is difficult to cover the full range of output from room temperature to 100°C
