Description

A washing machine control method

technical field

The invention relates to the technical field of washing machines, in particular to a control method for washing machines.

Background technique

At present, most washing machines have a self-cleaning program for the barrels to meet the needs of users to clean the dirt in the inner and outer barrels. However, ordinary users cannot accurately grasp the actual dirt situation between the inner and outer barrels. Users are required to subjectively judge the degree of dirtiness of the inner and outer barrels of the washing machine. Users can only Judging by subjective feeling whether it is necessary to clean the inner and outer tubs, there is a lot of dirt adhering to the inner and outer tubs, but the user does not know the situation and fails to clean the inner and outer tubs of the washing machine in time. Pollution, does not meet the washing trend of users' health. However, if the user frequently starts the bucket cleaning program, it is a waste, because a large amount of water and electric energy are required to execute the bucket cleaning program.

Furthermore, there are many kinds of cleaning agents for the tubs of washing machines, and different types of dirt and amounts of dirt are suitable for different cleaning agents for tubs and different dosages of cleaning agents for tubs. Reasonable use of bucket cleaning agent and dosage can achieve good cleaning effect. When the existing washing machine performs the bucket cleaning procedure, the selection of the type of the bucket cleaning agent and the dosage of the bucket cleaning agent are subjectively determined by the user, and there is no data basis. Moreover, the bucket cleaning procedure of the current washing machine is fixed, not The corresponding parameters will be adjusted according to the actual dirt situation.

In view of this, the present invention is proposed.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a washing machine control method, which judges the dirty condition of the washing tub according to the water quality information of the washing tub, adopts a corresponding tub cleaning scheme according to the contamination condition, and cleans the washing tub in a targeted manner, Ensure the cleaning effect of the washing tub.

For achieving the above object, the present invention adopts the following technical scheme:

A washing machine control method, comprising:

The washing machine controls the water into the washing tub;

The washing machine detects the water quality information of the water in the washing tub;

The washing machine sets a tub cleaning program according to the water quality information.

Preferably, the setting of the bucket cleaning procedure includes determining the corresponding bucket cleaning agent and/or the dosage of the bucket cleaning agent and/or the bucket cleaning method.

In the above solution, the washing machine feeds water into the washing tub, and the incoming water directly contacts the dirt on the inner and outer tubs of the washing tub, and part of the dirt falls off and mixes with the water. The water quality test of the water in the washing tub can detect the inside and outside of the washing tub. The dirt information on the bucket and the water quality information of the washing machine's water quality affect the cleaning of the bucket cleaning agent. Therefore, the washing machine provides a specific bucket cleaning plan according to the water quality information in the washing bucket, which includes bucket cleaning agent and/or bucket cleaning. dosage and/or bucket cleaning method.

Preferably, the water quality information includes a plurality of water quality parameters, and the washing machine sets the bucket cleaning program according to each water quality parameter.

The water quality information includes any one or more of TDS parameters, water temperature parameters, TOC parameters, turbidity parameters, pH parameters, water hardness parameters, and detergent residue parameters.

Wherein, the washing machine detects the pH parameter of the water in the washing tub, and determines the corresponding tub cleaning agent according to the pH parameter. Specifically, there are various barrel cleaning agents on the market now. Different brands of barrel cleaning agents have different compositions and are suitable for cleaning different soiling conditions. In large aspects, barrel cleaning agents are divided into acidic, alkaline and neutral. , Acidic water quality is suitable for using acidic barrel cleaning agent, and alkaline water quality is suitable for alkaline barrel cleaning agent. According to the main treatment effect, barrel cleaning agent is divided into barrel cleaning agent for descaling and barrel cleaning for sterilization. agent.

Specifically, if the pH of the water detected by the washing machine is acidic, it is determined that an acidic bucket cleaning agent is required to ensure the cleaning effect; if the pH of the water detected by the washing machine is alkaline, it is determined that an alkaline bucket cleaning agent is required, and the If the PH of the water detected by the washing machine is neutral, it is determined that an acidic, alkaline and neutral bucket cleaning agent can be applied.
