Instant heating device and control method thereof, calibration equipment and control method thereof and medium

Technical Field

The invention relates to the technical field of instant heating, in particular to an instant heating device and a control method thereof, calibration equipment and a control method and medium thereof.

Background

The instant heating product has the advantages of energy conservation, smaller volume, low cost and the like, and is increasingly popularized in daily life. However, in actual products, due to the limitation of the production process level, the water flow speed tolerance of the water pump at the same driving voltage is ± 20%, and further variation of the rotational speed decay of the water pump may occur after the user uses the product for months or years. For the quantitative water outlet module of the instant heating product, because the control main board cannot learn the corresponding relationship between the driving value and the water flow speed of each machine, the control software can only use the default driving value-water flow speed curve to calculate the water outlet amount, but because the tolerance of the water pump is too large, the characteristic curve of the water pump of each machine may have a large deviation from the default curve, and the quantitative water outlet accuracy of the water dispenser is inaccurate.
