Smart power grid-based washing machine power supply detection and control method

Abstract

The invention discloses a smart power grid-based washing machine power supply detection and control method. The method comprises the following steps of: ensuring that a washing machine comprises an electric network source input interface and an energy storage power supply input interface and an energy storage power supply deeply discharges or supplies power; setting a washing procedure; judging whether the capacity of the current electrical quantity of the energy storage power supply is more than or equal to or less than set washing procedure power consumption; when the capacity of the current electrical quantity of the energy storage power supply is more than or equal to the set washing procedure power consumption, supplying power by using the energy storage power supply; and when the capacity of the current electrical quantity of the energy storage power supply is less than the set washing procedure power consumption, switching to a power grid to supply power or supplying power by using the power grid when deep discharge is performed. The power supply by an electric network source comprises the following steps of: when the power grid is in a wave trough, starting to run a procedure until the procedure is finished; and when the power grid is in a wave crest, entering a power saving mode, or not starting the procedure and running or continuously washing when the power grid is in the wave trough. The smart power grid-based washing machine power supply detection and control method can reduce the burden of the power grid and saves electricity cost.

Description

technical field [0001] The invention relates to a washing machine control method, in particular to a washing machine power detection control method based on a smart grid. Background technique [0002] With the continuous improvement of living standards at present, washing machines have entered almost all families, especially in urban families who live more affluently, and the ownership rate of washing machines even exceeds 100%. The power energy used by the current washing machine is 100V / 220V grid power supply, and the user only needs to insert the power plug into the socket when using it. With the gradual reduction of energy on the earth and the increase of power generation costs, electricity prices continue to rise. In many cases, even if there is money, there is no electricity available, because many cities are limiting electricity, and there is a shortage of electricity. Simply using grid power to power washing machines has caused loss of electrical energy. [0003] N...

Problems solved by technology

[0012] No matter what the current washing machine is, after starting up, as long as the user selects and starts the washing program, the washing machine will start to run all the selected washing programs. Although there is a reservation function, the washing program can be delayed, but the reservation function does not have the ability to judge the load. function, as long as the scheduled time is up, the washing process will start, and it is impossible to selectively start the washing process according to the peak or valley of electricity consumption, which not only increases the burden on the power grid, makes the load of the power grid unbalanced, but also increases the electricity bill for laundry during peak power consumption. high
