Embodiment 1

[0043] The high-power heating tube and the low-power heating tube are installed on the outer tub of the washing machine. The high-power heating tube and the low-power heating tube are installed on the same base. The battery uses 24V20AH. The power of the high-power heating tube is 1800W, and the low-power heating The power of the tube is 300W. When the high-temperature heating program selected by the user starts during the laundry process, the main control unit of the washing machine immediately switches the power input to the grid power input through the power switching unit (this process is a forced switching, that is, no matter the current power input is the battery or the grid power supply). At the same time, the relay switch K1 of the high-power heating tube is turned on through the heating tube control unit, and the relay switch K2 of the low-power heating tube is kept in an off state. The main control unit of the washing machine starts to execute the heating program and ...

Embodiment 2

[0045] The high-power heating tube and the low-power heating tube are installed on the outer tub of the washing machine. The high-power heating tube and the low-power heating tube are installed on the same base. The battery uses 24V20AH. The power of the high-power heating tube is 1800W, and the low-power heating The power of the tube is 300W. When the user selects the low-temperature heating program during the laundry process, the main control unit of the washing machine obtains the capacity value of the current battery power through the power analysis unit, including two results: (1) The remaining power of the current battery is enough to support the low-temperature heating program, and the main control unit of the washing machine obtains the capacity value of the current battery through the power analysis unit. The switching unit switches the power input to the storage battery (this process is forced switching, ie no matter the current power input is the storage battery or t...

Abstract

The invention discloses system and method for automatically switching the input power according to the heating power of a washing machine, relating to the field of home appliances. The system comprises a grid power input interface, an energy-storage power input interface, heating pipes, a washing machine main control unit and a display screen, wherein the display screen, the grid power input interface and the energy-storage power input interface are respectively connected with the washing machine main control unit, and the heating pipes are powered by the grid power input interface and the energy-storage power input interface at the same time or respectively under the control of the washing machine main control unit. The scheme is suitable for the electric equipment using a plurality of power supplies and can rationally match a heating control system according to the powers provided by different energies and rationally utilize various energies, thereby not only avoiding the lifespan decrease or damage of the input energy caused by mismatching between the power provided by the input energy and an electric device, but also preventing the problem that the power provided by the input energy is not enough to drive the electric device so that the predicted effect cannot be achieved.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine system and method capable of automatically switching input power sources according to the heating power when a heating program is selected in a washing program. Background technique [0002] In real life, the lack of energy resources has become the top priority for human survival. Existing energy sources such as water, coal, and oil will be exhausted in a few years according to the current speed and method of use. Therefore, various industries and fields are trying to find ways Find alternative energy sources, or find ways to rationally utilize existing energy sources. In the prior art, there is also a way of mixing multiple energy sources, which converts natural energy such as light and wind into energy that can be used by people, and also tries to save energy on the existing electrical equipment and improve energy utilization. Rate. The above-mentioned measur...
