Embodiment Construction

[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Such as figure 1 , is a structural schematic diagram of the washing machine. An external power input interface a is installed on the washing machine 1. The power input interface a is directly connected to the energy storage power supply, which is also the energy storage power supply 3 . At the same time, the washing machine 1 also has the original power input interface b, which is connected to the grid power supply 2, figure 1 What is shown is the circuit diagram of the system when only two sets of power supplies, the energy storage power supply and the grid power supply, are used to power the washing machine. The latter involves the combination of the three systems to supply power to the washing machine, which are also the...

Abstract

The invention relates to a method for detecting and controlling the power supply of a washing machine, which at least comprises a grid power supply and an energy storage power supply, wherein if the two power supplies are both connected before a program is set, or only the energy storage power supply is connected and the electric quantity is sufficient, or the energy storage power supply is not connected until the program is set and the electric quantity of the energy storage power supply is sufficient, the washing machine preferentially uses the energy storage power supply for power supply; and when the electric quantity of the energy storage power supply is insufficient, the grid power supply is switched to. The method saves the electric energy of the grid, relieves the electric tension and saves the electric cost for users.

Description

technical field [0001] The invention relates to a washing machine control method, in particular to a washing machine power detection control method. Background technique [0002] At present, with the continuous improvement of living standards, washing machines have entered almost all households, especially in urban households with relatively affluent lives. The ownership rate of washing machines even exceeds 100%, but the power energy used by current washing machines is 100V / 220V grid power supply, users only need to plug the power plug into the socket when using it. However, with the gradual reduction of energy on the earth and the increase of power generation costs, the price of electricity continues 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 electric energy. Simply using the grid power supply to power the washing machine has caused a loss of electric energy. ...
