AI Technical Summary

Technical Problem

The power control of existing storage water heaters fails to fully consider the heat loss rate of the water in the water heater, resulting in low insulation control accuracy, affecting the user experience and increasing component losses.

Method used

By obtaining the insulation dissipation power ratio of the water heater, the output power of the electric heating unit is controlled based on this ratio. Combined with the parallel and series combination of thyristors and relays, precise power control of the electric heating unit is achieved, avoiding overload of individual components and extending service life.

Benefits of technology

It improves the power control accuracy of the water heater in the insulation state, reduces energy waste, extends component life, and ensures temperature stability and user experience.

Abstract

The present invention discloses a water storage water heater and a control method thereof. The water heater includes an electric heating unit. The control method comprises the following steps: obtaining the water heater's thermal insulation dissipation power ratio; and controlling the output power of the electric heating unit when the water heater is in a thermal insulation state based on the thermal insulation dissipation power ratio. The thermal insulation dissipation power ratio is used to characterize the heat loss rate of the water in the water heater. When controlling the output power of the electric heating unit in the thermal insulation state of the water storage water heater of the present invention, the heat loss rate of the water in the water heater should be fully considered. This allows the water heater to more accurately control the output power of the electric heating unit, avoiding energy waste caused by high thermal insulation power and preventing the failure to achieve a thermal insulation effect due to low thermal insulation power.
