Tableware condition judgment method in cleaning machine, cleaning method of cleaning machine and cleaning machine

Abstract

The invention relates to a tableware condition judgment method in a cleaning machine. The method comprises the following steps: controlling water to enter a cleaning cavity of the cleaning machine to an initial water quantity W0; tableware in the cleaning cavity is controlled to be circularly sprayed, and water volume data W at the bottom of the cleaning cavity are detected and calculated; calculating water volume difference data delta W = W0-W; and according to the preset water quantity difference-tableware quantity relation information, the tableware quantity information in the cleaning cavity is obtained based on the delta W. The tableware condition judgment method is low in cost, and the more accurate tableware quantity condition can be obtained. The invention further relates to a cleaning method of the cleaning machine, information of the number of the tableware in the cleaning cavity is obtained through the tableware condition judging method, the water amount in the cleaning cavity is adjusted according to the information of the number of the tableware, and the adjustment of the water amount in the cleaning cavity comprises the steps of keeping, increasing or decreasing the water amount in the cleaning cavity. And meanwhile, the working parameters of the spraying mechanism are adjusted according to the adjusted water inflow information in the cleaning cavity. The invention relates to a cleaning machine applying the tableware condition judging method or the cleaning method.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a method for judging the condition of tableware in a washing machine, a washing machine cleaning method applying the method for judging the condition of tableware, and a washing machine using the method for judging the condition of tableware or the washing machine cleaning method. Background technique [0002] The number of tableware is an important parameter for determining the cleaning parameters in the washing machine. In the prior art, some detection devices are used to detect the number of tableware in the washing machine, and then the corresponding cleaning parameters are matched according to the detection results, thereby achieving energy saving and cleaning. Balanced matching of effects. [0003] At present, the detection methods of the number of tableware used in the washing machine are as follows. [0004] 1. Use the weight sensor to obtain the weight of the d...

Problems solved by technology

This technology needs to set up corresponding image acquisition equipment, and at the same time has high requirements for data processing chips, which greatly increases the cost of equipment and is relatively complicated to implement.

And the recognition rate is limited by factors such as the resolution of the camera, whether the placement action blocks the tableware, etc., and the recognition error rate is high
