Description

Control device and control method for washing and protecting equipment Technical Field The invention belongs to the technical field of household appliances, and particularly relates to a control device and a control method of washing and protecting equipment. Background With the progress of science and technology and society, washing and protecting equipment functions are more and more, and accordingly more and more loads need to be driven, but because the space of a control board is limited, the number of interfaces is limited, and the situation that partial functions cannot be realized because too much loads cannot be driven due to insufficient interfaces can occur. In the prior art, a switch in a control loop generally controls a load, that is, a plurality of switches are needed for controlling a plurality of loads, but because the size of a control board is limited by a structural space, the control board cannot be adjusted at will, and the situation that new functions cannot be added because interfaces and switches cannot be added due to insufficient space can be caused.
