A water heater control method against self-starting

Abstract

A water heater control method against self-starting, which is characterized in that it includes the following steps: (1) Standby; (2) Judging whether t exceeds the set Ts, if so, repeat this step; if not, perform the next step; (3) This time t As the sample time Ti, add 1 to the number of samples n; (4) judge whether n is greater than or equal to N, and if so, execute the next step; if not, return to step (2); (5) calculate the clustering algorithm to obtain the largest number of classes Ct; ( 6) Take the maximum time in Ct as Td; (7) Determine whether the variation of Td for m consecutive times is less than Tmin, if so, go to step (9); if not, perform the next step; (8) Remove the farthest time point, the sample Subtract 1 from the number n, and return to step (2); (9) Take the maximum value of Td as the final TT0 of the system. The advantage of the present invention is that: according to the increase in the number of samples, the delay time parameters inside the system are updated in real time, and at the same time, the principle of clustering algorithm is adopted to find the best delay time for boiling water in the actual use process to ensure the performance of hot water and reduce the Probability of false start.

Description

technical field [0001] The invention relates to a water heater device, in particular to an anti-self-starting water heater control method. Background technique [0002] In the prior art, household gas water heaters usually use the water flow signal as the starting signal of the water heater. When the water flow is detected to be greater than the set flow value, the water heater is started, and when the water flow is less than the set flow value, the water heater is turned off. However, in In actual use, due to the unreasonable layout of water pipes in some households, when turning on cold water or using flush toilet equipment, it may cause changes in the water pressure of the hot water pipeline, thereby detecting the water flow, and the water flow signal will vary according to different pipelines. Lasting for different times will eventually lead to misoperation of the water heater. This is the self-starting phenomenon of traditional water heaters, which will bring a lot of i...

Problems solved by technology

However, the delay time used in the current boiling water delay method is a fixed value, that is, the delay time is a preset fixed value, which cannot be guaranteed to be applicable to different household pipelines, and there are some families where the delay time is too long. If the time is short, the self-starting phenomenon still occurs; or there is also the possibility that the delay time of some households is too long, which greatly sacrifices the hot water performance and affects the comfort of users.
