Description

Washing machine dehydration control method and control device

Technical field

The present disclosure relates to the technical field of washing machine dehydration, and relates to a washing machine dehydration control method and a control device, for example.

Background technique

The implementation procedure of the automatic washing machine standard procedure is as follows: start-inlet water to set water level-washing-drainage-intermittent dewatering-continuous dehydration-inertial dehydration-influent to set water level-rinsing 1-drainage-intermittent dehydration-continuous dehydration- Inertial dewatering - Influent to set water level - Rinse 2 - Drainage - Intermittent dewatering - Final continuous dewatering - Inertial dehydration - End. The above-mentioned washing program is defined as a standard washing, and the washing machine using the above-described washing program method has an imbalance correction, and the method is to detect the unbalanced switch of the washing machine during dehydration, and the unbalanced switch is normally closed, that is, also called normally closed. The switch, if the unbalanced switch operates, that is, the short-time switch is turned off and then closed, the controller determines that the laundry in the washing machine barrel is unbalanced and performs an imbalance correction.

The unbalance correction is handled as follows: After the brakes, the water is injected to the original set water level to balance the current washing water flow, washing for 60 seconds or 90 seconds, draining, and continuing the original dehydration process. The above imbalance correction takes 5-6 minutes and consumes a bucket of wash water. If the third collision occurs after adjusting twice, an alarm is given to prompt the user to take measures to eliminate the imbalance.

For the above unbalanced processing method, there are the following disadvantages: First, each bucket consumes one bucket of washing water, which wastes water resources; secondly, if it is still started according to the original startup mode, it is easy to hit the bucket again. When the bucket is hit three times, it will cause an alarm. After the alarm, the user cannot run the program normally, and the alarm is too frequent, which affects the user's feeling of use.

In step 30, when X+1 collision buckets occur, water is introduced into the dewatering bucket, the distribution of the load in the dewatering bucket is changed, and dehydration is continued.

In this embodiment, X can select the value of the number of collisions of the barrels in the whole dehydration process. For example, in the whole dehydration process, the brakes are used after the collision of the buckets 3 times, 5 times and 8 times, and the corresponding buckets are 4 times. Water was introduced into the dewatering tank after 6 and 9 times. By counting the number of brakes, it is known that the brakes are 3 times. In addition, you can also choose to brake when you hit the bucket an odd number of times, and fill the bucket into the dewatering bucket when you hit the bucket even times. The dehydration control method of the washing machine in this embodiment can solve the problem of uneven distribution of load in the dewatering bucket when the user saves water, increases the number of attempts to start dehydration, and improves the user's feeling.

The washing machine in this embodiment may be a pulsator washing machine.

As shown in FIG. 2, the washing machine dehydration control method in this embodiment includes the following steps.

In step 10, the number of collision buckets is counted during dehydration.

In step 20, when X times of collision occurs, a braking procedure is applied to the dewatering bucket, and the brake is used. Sex changes the distribution of load in the dewatering bucket, counting the number of brakes and continuing to dewater.

In step 40, if a Y-brake occurs and a collision occurs after the dehydration process is started again, the washing machine issues an alarm to remind the user to take measures; if the barrel does not occur after the dehydration process is started again, the dehydration is performed again, and Y is at least equal to 1.

For example, when Y=3, after 3 times of braking, after the dehydration program is started again, the barrel still occurs, and the washing machine issues an alarm to remind the user to take measures, and the user performs the next dehydration after the processing is completed.

As shown in FIG. 3, in this embodiment, a washing machine dehydration control method is provided, which includes the following steps.

In step 300, dehydration begins.

In step 310, the washing machine is controlled for normal dewatering.

In step 320, it is determined whether a first collision occurs, and if so, braking is performed, the number of brakes is counted and dehydration is continued, and step 330 is continued, and if no, step 310 is performed.

In step 330, it is determined whether a second collision occurs, and if so, water is introduced into the dewatering tank, the load distribution is changed, the dehydration is continued, and step 340 is continued, and if no, step 310 is performed.

In step 340, it is determined whether a third collision occurs, and if so, braking is performed, the number of brakes is counted and dehydration is continued, and step 350 is continued, and if no, step 310 is performed.

In step 350, it is determined whether a fourth collision occurs, and if so, water is introduced into the dewatering tank, the load distribution is changed, dehydration is continued, and step 360 is continued, and if no, step 310 is performed.

In step 360, it is determined whether a fifth collision occurs, and if so, the brake is performed, the number of brakes is counted and dehydration is continued, and step 370 is continued, and if no, step 310 is performed.

In step 370, it is determined whether the number of brakes has reached three times. If yes, step 380 is performed, and if not, step 310 is performed.

In step 380, after determining that the number of brakes has reached three times, whether the next dehydration has a collision bucket, if yes, proceed to step 390, otherwise step 310 is performed.

In step 390, the washing machine issues an alarm to remind the user to take measures. After the user corrects, step 300 is performed.

In this embodiment, N=2, Y=3, that is, the bucket is hit six times, and the washing machine issues an alarm to remind the user to take measures. The dehydration control method of the washing machine in this embodiment improves the related art that each collision bucket needs to pass through water to improve the uneven load in the dewatering bucket, thereby saving water resources.

As shown in FIG. 4, the embodiment provides a washing machine dehydration control device, comprising: a collision barrel sensing module 410, configured to determine whether a collision bucket occurs when the washing machine performs a dehydration process.

The control module is configured to determine whether the washing machine has a collision problem, and controls the washing machine to perform a normal dehydration process when there is no collision problem.

When the washing machine executes the dehydration program, the collision barrel sensing module judges whether the collision barrel is in the washing process when the washing machine performs the dehydration process. If it is judged that the collision barrel does not occur, the subsequent dehydration process is normally performed, and if it is judged that the washing machine has hit the barrel, the collision is performed. The bucket number counting module counts the number of collision buckets in the washing machine dehydration program, and judges the number of collision buckets through the control module. If the bucket is hit an odd number of times, the brake is performed, and the brake is applied. The number of vehicles is counted, and then dehydration is continued; if the bucket is hit an even number of times, water is poured into the dewatering tank to change the load distribution, and dehydration is continued; if it is not hitting the barrel, the normal dehydration process is performed. The brake number counting module is used to count the number of brakes. When the number of brakes reaches Y times and a collision occurs after the dehydration program is restarted, the control module controls the washing machine to issue an alarm to remind the user to take measures. The control device can save water resources, reduce the number of alarms and enhance the user experience when the washing machine is dehydrated.
