Electric water heater and heating control method thereof

Abstract

The invention discloses an electric water heater and a heating control method thereof. The heating control method comprises steps as follows: the total time for heating control is arranged and equally divided into a plurality of work period, and each day in each work period is divided into a plurality of time slots; in the first work period, the electric water heat is controlled to carry out heating or heat preservation, so that reserved hot water is kept in the electric water heater; the second work period is entered, whether the number of days, in which water is discharged at the same time slot, in a plurality of days in the first work period is larger than the predetermined number of days (N), is judged; if the number of days is larger than A, the time slot is a regular time slot; if not, the time slot is an irregular time slot; in the second work period, the electric water heat is controlled to carry out heating or heat preservation, so that reserved heat water volume is kept in the regular time slot; work periods after the second work period are entered sequentially, in each work period, whether time slots are regular or irregular time slots is judged, and the electric water heater is controlled to carry out heating or heat preservation according to the result. According to the heating control method, water use habits of users can be followed up, and heating is adjusted in real time.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a heating control method for an electric water heater and an electric water heater adopting the heating control method. Background technique [0002] The heating mode of the electric water heater is generally to directly heat to the user's set temperature. No matter whether the user uses water or not, the heat preservation and heating will continue to keep the water in the electric water heater near the user's set temperature. However, most users do not unplug the power supply. habit, thus causing the electric water heater to heat repeatedly, wasting energy. For this reason, in the related art, the frequency calculation method is used for heating control, and if the frequency exceeds a certain frequency in the same period, it is considered that hot water is needed in that period, otherwise, hot water is not needed. However, in the actual use process, the water consumption ...

AI Technical Summary

Problems solved by technology

However, in the actual use process, the water consumption of different users varies greatly, resulting in the ineffective use of this function, and because the user's behavior of using hot water cannot be precise, the application of this heating control method is relatively limited.
