Control method and controller of instant water boiler, instant water boiler and medium

Abstract

The embodiment of the invention provides a control method and controller of an instant water boiler, the instant water boiler and a medium. A multi-mode heating manner is adopted, when the power of a heater meets the requirement for full-speed hot water output, full-speed water output is achieved, when the power of the heater does not meet the requirement for full-speed hot water output, speed-reduction water output is achieved, equipment achieves the highest flow hot water output efficiency, and meanwhile the equipment has any interval with the water temperature being adjustable. In addition, the heated water temperature is accurate, the phenomenon that the temperature is too high or too low cannot happen, the probability that the temperature is too high and water vapor is splashed to burn out the heater is reduced, and the drinking water safety is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of control, in particular to a control method and a controller of an instant hot water machine, an instant hot water machine and a medium. 【Background technique】 [0002] The instant water boiler adopts pipeline heating to realize the instant water flow, and the energy source continuously provides constant temperature boiling water, which basically realizes "instantly open and use, no power consumption when not in use". With the needs of consumers, portable instant hot water machines are more able to adapt to the needs of different groups of people. Most of the portable instant hot water machines in the prior art currently use intermittent heating or thyristor power adjustment heating. In practical applications During the process, the outlet water flow rate of the hot water boiler is constant. At this time, the heating power of the heater is adjusted by comparing the actual outlet water temperature with th...

With the needs of consumers, portable instant hot water machines are more able to adapt to the needs of different groups of people. Most of the portable instant hot water machines in the prior art currently use intermittent heating or thyristor power adjustment heating. In practical applications During the process, the outlet water flow rate of the hot water boiler is constant. At this time, the heating power of the heater is adjusted by comparing the actual outlet water temperature with the target temperature, but it is easy to cause a large deviation between the actual outlet water temperature and the target outlet water temperature, such as If the speed is too small, if the target outlet temperature is set to 60°C, the actual temperature of the outlet water may have reached 100°C. At this time, the hot water may have boiled and a large amount of steam will be generated, and the water vapor will splash and even burn out the heater; For example, if the water outlet speed is too high, if the target outlet water temperature is set to 60°C, the actual water will be normal temperature water, and the water temperature is too low

To sum up, the temperature of the water produced by the portable instant hot water machine in the prior art is inaccurate. If the temperature is too high, the water vapor will splash and burn out the heater. If the water temperature is too low, it is not safe to drink.
