Problems solved by technology

[0002] The electric water heaters in the related art usually have the function of detecting the remaining hot water. The detection result of the remaining hot water is estimated based on the temperature value of the water in the tank. The test results deviate greatly from the actual value, and the accuracy cannot be guaranteed

Abstract

The invention discloses a remaining hot water detection device and a time correction method of an electric water heater. The time correction method in the detection of the remaining hot water of an electric water heater includes the following steps: S1: Presetting each temperature range in a plurality of temperature ranges S2: Real-time detection of the actual water temperature of the electric water heater in the state of water use; S3: When it is detected that the actual water temperature at two time points is the same as the two temperature endpoints of one of the temperature intervals, record the above two The actual time interval of a time point; S4: Calculate the average value of multiple actual time intervals corresponding to the same temperature interval; S5: Use the average value as a correction parameter to correct the initial time interval of the corresponding temperature interval. The time correction method in the detection of the remaining hot water of the electric water heater according to the embodiment of the present invention can adaptively correct the time parameter in the remaining hot water, thereby improving the accuracy of the detection result of the remaining hot water.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a device for detecting remaining hot water of electric water heaters and a method for correcting time in detecting remaining hot water of electric water heaters. Background technique [0002] The electric water heaters in the related art usually have the function of detecting the remaining hot water. The detection result of the remaining hot water is estimated based on the temperature value of the water in the tank. The test results deviate greatly from the actual value, and the accuracy cannot be guaranteed. Contents 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. Therefore, the present invention proposes a residual hot water detection device for an electric water heater, which can realize self-adaptive error correction and has the advantages of accurate...
