In order to solve the technical problems, the invention adopts the technical scheme that:

a control method of a washing machine, comprising:

the washing machine sets a minimum water temperature T0 for washing the laundry;

detecting the water inlet temperature T1, and judging whether the water inlet temperature T1 is lower than the lowest water temperature T0;

if the judgment result is yes, the water temperature of the heated washing water is controlled not to be lower than the minimum water temperature T0, and if the judgment result is no, the washing machine executes the washing program selected by the user.

In the scheme, the washing machine adjusts the temperature of the inlet water to be not lower than the lowest water temperature T0, so that the washing machine still has a good washing effect even in seasons with low air temperature, and the user experience is improved.

Preferably, the minimum water temperature T0 is a factory default value of the washing machine; preferably, the default value is an empirical value obtained in a number of washing experiments.

In the above scheme, the minimum temperature T0 is set when the washing machine leaves the factory, so that the washing machine can determine the relationship between the inlet water temperature and the minimum water temperature T0 to determine whether to heat the washing water and ensure the washing effect of the clothes whenever the washing machine washes the clothes.

Or set by the user selection, in the scheme, after the user selects the lowest water temperature T0, the washing machine stores the lowest water temperature T0, so that the size relation between the inlet water temperature and the lowest water temperature T0 is detected at each washing.

Or the washing machine is automatically set.

For example, the washing machine recognizes environmental information, laundry care agent information (detergent, softener, etc.), and automatically sets the minimum temperature T0 according to the recognized information, thereby obtaining a more scientific minimum temperature T0.

Preferably, the lowest water temperature T0 is 12-20 ℃;

more preferably, the minimum water temperature T0 is 15-17 ℃.

Preferably, the washing machine may receive a user input of a set water temperature T2, select a target temperature from the minimum water temperature T0, the set water temperature T2 and the inlet water temperature T1, and perform a washing process after controlling the washing water to be heated to the target temperature.

In the above solution, the washing machine may obtain three temperatures, i.e., the minimum water temperature T0, the set water temperature T2, and the inlet water temperature T1, and select a target temperature among the three temperatures, which satisfies the condition that the target temperature is not lower than the minimum temperature T0, while giving priority to user selection and saving energy.

Preferably, the control method of the washing machine includes the steps of:

s1, detecting the water inlet temperature T1 by the washing machine, judging whether the water inlet temperature T1 is lower than the minimum water temperature T0, if so, entering step S2, otherwise, entering step S3;

s3, selecting target temperature from the inlet water temperature T1 and the set water temperature T2, controlling the washing water to be heated to the target temperature, executing the washing process, and ending the control.

In the scheme, the selection range of the target temperature is determined according to the size relation between the inlet water temperature T1 and the minimum water temperature T0.

Preferably, step S2 includes:

s21, the washing machine judges whether the lowest water temperature T0 is lower than the set water temperature T2, if so, the step S22 is executed, otherwise, the step S23 is executed,

and S22, the washing machine determines that the minimum water temperature T0 is the target temperature, and executes the washing process after controlling the washing water to be heated to the minimum water temperature T0, and the control is finished.

In step S2, when the set water temperature T2 is not set by the user, the washing machine determines that the minimum water temperature T0 is the target temperature and controls the washing water to be heated to the minimum water temperature T0, and then performs the washing process.

Preferably, step S3 includes:

s31, the washing machine judges whether the inlet water temperature T1 is lower than the set water temperature T2, if yes, the step S32 is carried out, and if not, the step S33 is carried out;

s32, the washing machine determines that the set water temperature T2 is the target water temperature, and executes the washing process after controlling the washing water to be heated to the set water temperature T2, and the control is finished;

s33, the washing machine determines the water inlet temperature T1 as the target temperature and controls the washing process to be executed after the water inlet is finished.

Preferably, in step S3, when the user does not set the set water temperature T2, the washing machine determines that the inlet water temperature T1 is the target water temperature, and controls the inlet water to the set water level, and then performs the washing process.

Preferably, the washing machine comprises a water inlet pipeline, a temperature sensor is arranged on the water inlet pipeline, and the temperature sensor detects the water inlet temperature T1 in the water inlet process.
