Warm water outlet temperature control method of water dispenser and water dispenser

Abstract

The invention discloses a method for controlling the warm water outlet temperature of a water dispenser and a water dispenser. The method comprises: obtaining the hot water temperature range, the cold water temperature range and the current expected warm water temperature of the warm water pipeline; Temperature interval, determine the mapping relationship between the warm water outlet temperature of each warm water pipeline and the ratio of hot water flow and cold water flow; obtain the real-time cold water temperature of the refrigeration system and the real-time hot water temperature of the heating system at the current moment; according to the mapping relationship, cold water real-time temperature, The real-time temperature of hot water and the expected temperature of warm water can be used to obtain the flow rate of cold water supply and hot water supply of the water dispenser; control the cold water valve to make the refrigeration system provide cold water to the warm water pipeline with the flow of cold water supply, and control the hot water valve to make the heating system supply water with hot water The flow provides hot water to the warm water line. The invention provides a constant-temperature water supply scheme with simple pipeline structure, low power distribution power and unrestricted water flow rate.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a method for controlling the outlet temperature of warm water from a water dispenser and the water dispenser. Background technique [0002] With the improvement of living standards, people's requirements for drinking water are getting higher and higher. Drinking water machines with precise temperature determination have become an urgent need in many aspects of people's daily life. For example, if you want to achieve the best brewing of different types of tea The temperature of the water used for the effect must be as close as possible to the optimum brewing temperature. [0003] Water dispensers currently on the market generally only provide cold water (for example, the temperature range of cold water is 10°C to 20°C) and hot water (for example, the temperature range of hot water is 85°C to 95°C). It is to dynamically adjust the heating power of the heater of the water dis...
