Intelligent control method of electric water heater and control circuit board

Abstract

The invention discloses an intelligent control method of an electric water heater and a control circuit board. The intelligent control method of the electric water heater comprises the steps of S101,collecting parameter information, water yield, water outflow temperature of the electric water heater, the temperature pre-set by a user and the position information of the user; S102, calculating thetemperature difference between the temperature pre-set by the user and the water outflow temperature of a water tank in the electric water heater; S103, estimating the time when the user gets home according to the position information of the user; and S104, performing heating starting action on the electric water heater according to the calculated temperature difference and the time when the usergets home. The electric water heater can perform heating in advance according to the time when each user gets home, repeated heating can be avoided, and accordingly energy can be saved.

Description

technical field [0001] The invention belongs to the technical field of electric water heaters, and in particular relates to an intelligent control method and a control circuit board of an electric water heater. Background technique [0002] The heating mode of the electric water heater is generally to directly heat to the user's set temperature, regardless of 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, but most users do not unplug the power Therefore, the electric water heater is heated repeatedly, wasting energy. [0003] However, since everyone has different temperature requirements for hot water and bathing time, it is difficult to set a uniform heating temperature to satisfy everyone's bathing comfort. And because the installation position of the electric water heater is mostly higher in the bathroom, it is often very inconvenient to adjust the tempera...

Problems solved by technology

[0002] The heating mode of the electric water heater is generally to directly heat to the user's set temperature, regardless of 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, but most users do not unplug the power habit, thus causing the electric water heater to heat repeatedly, wasting energy

[0003] However, because everyone has different temperature requirements for hot water and bathing time, it is difficult to set a uniform heating temperature to satisfy everyone's bathing comfort.

And because the installation position of the electric water heater is mostly higher in the bathroom, it is often very inconvenient to adjust the temperature of the hot water when taking a bath. Therefore, it is undoubtedly not convenient enough for everyone to reset a heating temperature suitable for themselves when taking a bath.
