Problems solved by technology

This water level correction control method mainly has two defects: one, the accuracy of water level correction using this method is low, and there is no specific and accurate correction calculation method; two, especially for some pulsator washing machines or drum washing machines with heating function In other words, not only the accuracy of water level correction is low, but also more heated water will cause waste of energy

Embodiment 1

[0047] This preferred embodiment provides a method for correcting and controlling the water level of a washing machine. Such as figure 1 As shown, the control method includes the following steps:

[0048] Step 1. After the washing machine completes the water intake, calculate the actual water intake value according to the formula;

[0049] Step 2. Judging the actual water inflow value V 实 Is it less than the preset water intake value V 预 , preferably, judging the actual water inflow value V 实 Is it less than the preset water intake value N*V 预 , N is the correction coefficient, if yes, go to step 3, otherwise go to step 4;

[0050] Step 3. Calculate the water replenishment working time of the water inlet valve to replenish water;

[0051] Step 4, the water intake ends.

Embodiment 2

[0053] This preferred embodiment provides a method for correcting and controlling the water level of a washing machine. Such as figure 2 As shown, the control method includes the following steps:

[0054] Step 1. The water inlet valve acts to enter the water, and the temperature sensor detects the initial water temperature value T 初 ;

[0055] Step 2. Record the water intake time t, heating time tn, and water temperature value T after heating 末 ;

[0056] Step 3, according to the formula V=1000*P*t / [C*ρ*(T 末 -T 初 )] Calculate the actual water inflow value V 实 ;

[0057] Step 4. Judging the actual water inflow value V 实Is it less than the preset water intake value V 预 , preferably, judging the actual water inflow value V 实 Is it less than the preset water intake value N*V 预 , N is the correction coefficient, if yes, go to step 5, otherwise go to step 6;

[0058] Step 5, according to the formula tn=K*(V 预 -V 实 ) / a Calculate the water replenishment working time of ...

Embodiment 3

[0061] This preferred embodiment provides a method for correcting and controlling the water level of a washing machine. Such as image 3 As shown, the method specifically includes the following steps:

[0062] Step 1. Determine the preset water intake value V according to the clothes to be washed 预 ;

[0063] Step 2. After the water inlet valve is activated, water starts to enter, and the temperature sensor detects the initial water temperature value T(n+1) of this water intake, where n is the difference between the current accumulated actual water inflow value and the preset water inflow value. The number of judgments;

[0064] Step 3. Determine whether the water intake is over, if yes, go to step 4, otherwise go to step 2 to continue this water intake;

[0065] Step 4. Record the water inflow information of this water inflow, that is, the water inflow time t of this time 1 n, heating time t 2 n, and the water temperature value T(n+2) after heating, and calculate the te...

Abstract

The invention discloses a washing machine water level correction control method and a washing machine and belongs to the field of washing device control methods and washing devices. A problem of lack of accurate water level correction control method in the prior art is solved. The washing machine water level correction control method comprises steps of calculating a third value according to heating time of the washing machine, water temperature difference value before and after heating, and a water feeding amount, and determining whether to supply water according to a comparison result between the third value and a target value. The washing machine employs the above water level correction control method. Water level correction accuracy can be improved by the use of the control method; and the washing machine is more convenient and clothes washed by the washing machine are cleaner.

Description

technical field [0001] The invention relates to a washing machine water level correction control method and a washing machine adopting the method. Background technique [0002] Washing machine is one of commonly used household appliances. Usually, during the laundry process, the clothes are placed first, and then the water level is calculated according to the water level value set by the user or the intelligent program to enter the water. However, because the clothes are immersed in the water and occupy part of the water volume and the clothes will raise the liquid level Due to the different water absorption of different clothes and other factors, there is a certain error in the water intake. [0003] The existing washing machine water level correction control method is as follows: after putting the clothes to be cleaned into the washing machine, manually select the target water level; automatically perform weight sensing to determine the actual water level; set the safety ...
