Embodiment Construction
[0023] A liquid heating device, see figure 1 and figure 2 , which includes a first water tank 1 , a second water tank 2 , a filter element 3 , a power module 4 , a heating module 5 , a reversing valve 6 , a flow limiting valve 7 , a temperature detection module 8 , an input module 9 , and a control module 10 . The first water tank 1 is used to load clean water, the second water tank 2 is used to load raw water, and the filter element 3 is arranged between the water outlet side of the second water tank 2 and the water inlet side of the first water tank 1, and the second water tank 2 The raw water is filtered by the filter element 3 to form clean water, which is stored in the first water tank 1 . The water inlet end of the power module 4 is connected with the first water tank 1, and the power module 4 provides power for the flow of clean water. In this embodiment, the power module 4 is a pump. The water inlet end of the heating module 5 is connected with the water outlet end ...

The invention relates to a control method of liquid heating equipment. The operation method comprises the following steps: acquiring a preset volume of required liquid; acquiring the temperature of upstream liquid of the heating module; selecting a first volume and a first temperature of the first liquid and a second volume and a second temperature of the second liquid according to the predetermined volume and the temperature of the liquid upstream of the heating module, the first volume and the second volume together providing the predetermined volume; the power module distributes the fifth liquid to the heating module, the heating module is closed, and the second water outlet outputs the fifth liquid; the power module distributes the first liquid to the heating module, the heating module is started to heat the first liquid to a first temperature, and the first water outlet outputs the heated first liquid; the power module distributes the third liquid to the heating module, the heating module is closed again, and the second water outlet outputs the third liquid absorbing the waste heat of the heating module; and the power module distributes the second liquid to the heating module, and the second liquid passes through the cooled heating module and then is output from the first water outlet.
Description
technical field [0001] The present invention relates to methods and apparatus for heating a predetermined volume of water to a desired temperature, such as warm water for use in the preparation of infant formula or other food for infants and young children. Background technique [0002] Current manufacturing techniques make it infeasible to produce and store sterile infant formula that is then used to make infant milk. The World Health Organization (WHO) guides the preparation of infant formula ("Safe preparation, storage and handling of powdered infant formula: guidance", WHO, 2007), and therefore recommends mixing infant formula with water at a temperature greater than 70 °C Mixing to reconstitute to sterilize powdered infant formula that may be contaminated with harmful bacteria such as Enterobacter sakazakii and Salmonella. [0003] Current infant formula or infant food is typically reconstituted by using freshly boiled water in a kettle to sterilize the infant formula ...
