Problems solved by technology

[0008] As mentioned above, the washing machine provided by the prior art has the problem of increased product cost due to the addition of channels for providing clean water to the turbidity sensor.
[0009] Moreover, in the water supply structure of the washing machine provided by the prior art, the clean water at the initial stage of water supply dissolves the detergent and is supplied to the water tank during the process of passing through the detergent supply device, so the turbidity sensor actually detects the water that has become turbid The turbidity of the turbidity sensor makes it impossible to rely on the turbidity detection results of the turbidity sensor

Abstract

The invention discloses a household electrical appliance and control method, aim at calibrating a turbidity sensor by pure water so as to realize dependable turbidity detection. For that, the invention discloses a turbidity sensor for detecting water turbidity and a household electrical appliance as detergent supply apparatus provided with a pre-wash detergent input port and a main wash detergentinput port, and comprises the following procedures: supplies water through the pre-wash detergent input port, and judge if pre-wash program is selected or not after water supplying; when no pre-wash program is selected, calibration of a turbidity sensor is performed.

Description

technical field [0001] The present invention relates to a household appliance and a control method thereof, in particular to a household appliance equipped with a turbidity sensor for detecting water turbidity and a control method thereof. Background technique [0002] A washing machine is a representative household appliance that performs a washing program that uses water in which detergent is dissolved to separate stains from laundry, rinses foam in laundry with water that does not contain detergent, or rinses with residual detergent A series of washing programs such as spin program, spin program that dehydrates laundry by high-speed rotation, etc. [0003] At this time, reducing the washing time and water consumption becomes an important criterion for judging the performance of the washing machine. In order to reduce washing time and water consumption while maintaining a certain level of washing effect, the washing machine should be controlled to perform optimal washing ...
