Abstract

The invention discloses a device for detecting residual amount of hot water in an electric water heater and a time correcting method, wherein the time correcting method for detecting the residual amount of the hot water in the electric water heater comprises the following steps: S1, presetting an initial time interval of each temperature range in a plurality of temperature ranges; S2, detecting the actual water temperature of the electric water heater in time under the water consuming state; S3, recording actual time intervals of two time points when detecting that temperature values of actual water temperature at two time points are as same as that of two temperature endpoints in one temperature range; S4, calculating an average value of a plurality of actual time intervals corresponding to the same temperature range; S5, correcting the initial time interval of the corresponding time range by taking the average value as a correcting parameter. The time correcting method for detecting the residual amount of the hot water in the electric water heater disclosed by the embodiment of the invention can be used for self-adaptively correcting the time parameter of the residual amount of hot water, thereby improving the accuracy of the detection result of the residual amount of the hot water.

Description

Technical field [0001] The present invention relates to the technical field of electric water heaters, and in particular to a detection device for remaining hot water amount of electric water heaters and a time correction method in detecting remaining hot water amount of electric water heaters. Background technique [0002] Electric water heaters in related technologies usually have a remaining hot water detection function. The remaining hot water detection results are estimated based on the water temperature in the tank. However, due to differences in the manufacturing of electric water heaters and differences in the use environment, the remaining hot water The detection result deviates greatly from the actual value, and the accuracy cannot be guaranteed. Summary of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a remaining ho...
