Water dispenser and outgoing water temperature control method thereof

Abstract

The invention discloses an outgoing water temperature control method of a water dispenser. The method comprises the following steps that: S1, incoming water temperature and target outgoing water temperature are acquired; S2, initial heating power and initial flow rate are calculated according to the incoming water temperature and the target outgoing water temperature, and heating is performed according to the initial heating power; S3, actual outgoing water temperature is acquired, and the flow rate of a water pump is adjusted according to the actual outgoing water temperature; and S4, when a difference value between the actual outgoing water temperature and the target outgoing water temperature is smaller than a preset threshold value, heating power is adjusted according to the actual outgoing water temperature. According to the outgoing water temperature control method of the water dispenser of the invention, outgoing water temperature can be precisely controlled through coarse adjustment of the flow rate of the water pump and fine adjustment of heating power. The method can satisfy people's needs and bring conveniences to people's lives. The invention also discloses a water dispenser.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a water outlet temperature control method of a water dispenser and a water dispenser. Background technique [0002] At present, the existing water dispensers basically assume that the inlet water temperature is normal temperature, and calculate the heating power and flow corresponding to different outlet water temperatures according to different outlet water temperature requirements. However, if the inlet water temperature changes greatly, It will lead to a large difference between the outlet water temperature and the preset parameters, so that the purpose of accurately controlling the water temperature cannot be achieved, which brings inconvenience to people's lives. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical defects at least to a certain extent. [0004] For this reason, an object o...
