In a drum type washing machine, a side-open door body is generally used, and a door glass is provided on the door body for observing the internal washing condition of the drum type washing machine.

Based on this, the present application intends to provide a solution to the above technical problem, the details of which will be explained in the following embodiments.

Referring to fig. 1, fig. 1 is a flow chart of a foam eliminating method according to a preferred embodiment of the present invention. Prior to an embodiment of the present invention, the method comprises the steps of:

s100, when the main washing stage is finished and the main washing and draining stage is entered, setting a first preset time for the drainage pump to work and then standing for a first stop time;

in the embodiment of the present invention, the main washing stage refers to a main washing stage in the drum washing machine, but may be any washing stage. When the drum washing machine washes, namely the main washing stage, a large amount of detergent is added into the washing machine, and the drum moves during washing to drive the bubbles generated by the detergent to move to the door glass, so that the detergent can be fully discharged by setting the first preset time for the drainage pump to work (namely the drainage pump discharges water in the drum), and more bubbles can be prevented from being generated during subsequent main washing water. On the other hand, the drainage pump works for a long time, so that the proper first stop time can reduce the working pressure of the drainage pump and avoid the damage of the drainage pump.

After the first stop time forbidden by the drainage pump is finished, if the program of the main washing and drainage stage is not finished, the corresponding drainage pump works for the first preset time and then is stopped for the first stop time until the main washing and drainage stage is finished.

S200, when the drainage pump starts to work and reaches a second preset time, controlling the spray head to start spraying water and continuing for a first water spraying time;

on the basis of the embodiment, when the drainage pump starts to drain water, the spray head does not start to spray water until the drainage pump drains water for the second preset time, and the first water spraying time is continued; the first preset time is longer than the second preset time, namely when the drainage pump drains water, and the drainage pump drains water for a certain time, the spray head starts spraying water at the moment. Since the water level is high at the initial stage of water discharge, water resources for water discharge are wasted if water discharge and water discharge are performed simultaneously. After waiting for a certain time for drainage, the water level can be reduced, only a little detergent foam remains on the door glass correspondingly, and water resources can be saved to the greatest extent by spraying water at the moment, and a good foam eliminating effect is achieved.

S300, when the main washing and dewatering stage is detected to enter, setting the drainage pump to work for a first preset time and then to be static for a first stop time.

On the basis of the embodiment, when the main washing dewatering stage is needed after the main washing dewatering stage is completed, the drum dewaters the clothes in the drum, water in the clothes flows out, and the drainage pump works for the first preset time and then stops for the first stop time, so that the water can be drained better.

S400, judging the dehydration rotating speed of the roller, and controlling the spray head to start spraying water and continue for a first water spraying time when the rotating speed of the roller is less than or equal to a first preset rotating speed.

Based on the above embodiment, since the detergent remains in the laundry during the main washing stage, and the drum has a higher rotation speed during the dewatering, the detergent in the laundry is thrown out to the door glass to form detergent bubbles. Therefore, the detergent foam on the door glass needs to be removed, but at the moment, because the roller is in a dehydration state, the rotating speed of the roller is higher, and if the rotating speed of the roller is less than or equal to a first preset rotating speed, the spray head is controlled to start spraying water and continue spraying water for a first time. When the rotating speed of the roller is greater than the first preset rotating speed, the spray head stops spraying water, the roller at the moment has higher rotating speed, and if the spray head sprays water, water flow is dragged by the roller to form a ring shape and cannot be uniformly sprayed on the door glass, and detergent foam on the door glass cannot be well removed. Therefore, the rotation speed of the drum needs to be detected so as to judge whether the spray head needs to spray water during dewatering.

For example, the determining the dehydration rotation speed of the drum, when the rotation speed of the drum is less than or equal to a first preset rotation speed, after controlling the spray head to start spraying water for a first water spraying time, further includes:

s500, when the rinsing water inlet stage is started, controlling the spray head to spray water for a second water spraying time;

in the embodiment of the invention, after the main washing and dewatering stage is finished, because more detergent exists on the clothes, the clothes need to be rinsed, and as the name suggests, rinsing refers to washing off dirty water mixed with the detergent in the clothes, so as to ensure the cleanness of the clothes. Of course, whether to perform rinsing or not in actual use is user-configurable, for example, whether to add rinsing or not in the whole washing process can be configured on a control panel of the drum washing machine, which is the prior art and will not be described herein again.

When rinsing is needed, water starts to enter the roller, because a large amount of water enters in rinsing, more foams are formed by residual detergent in clothes, the spray head is controlled to start spraying water and continue spraying water for the second time, and detergent foams can be better prevented from remaining on the door glass.

For example, before controlling the spray head to start spraying water for the second water spraying time when the rinsing water inlet stage is entered, the method further comprises:

s410, judging whether a rinsing stage exists or not, and if so, rinsing water inflow;

in the embodiment of the present invention, since the rinsing step is not an essential step and is set according to the requirement, it is necessary to determine whether there is a rinsing stage, if so, the rinsing stage is entered, and correspondingly, the rinsing water-entering stage is entered, and if there is no rinsing stage, the drum washing machine is stopped after the main washing and dewatering stage is finished. It should be noted that, for judging whether there is a rinsing stage in the prior art, the determination can be implemented by programming, and the detailed determination steps are not described herein again.

S600, when the rinsing and draining stage is detected to enter, setting a first stop time for the drainage pump to stop after working for a third preset time;

on the basis of the above embodiments, after the rinsing water-in phase is finished, there is a rinsing washing phase, mainly a washing operation of the drum to the laundry, which will not be described herein. And after the rinsing and washing stage is finished, a rinsing and draining stage is carried out, and the third preset time for the drainage pump to work is set in the rinsing and draining stage, so that the detergent can be fully drained, and more foams can be prevented from being generated during the subsequent main washing and dewatering. On the other hand, the drainage pump works for a long time, so that the proper first stop time can reduce the working pressure of the drainage pump and avoid the damage of the drainage pump.

S700, when the drainage pump starts to work and reaches a fourth preset time, controlling the spray head to start spraying water and continuing for a first water spraying time;

on the basis of the embodiment, when the drainage pump starts to drain water, the spray head does not start to spray water until the fourth preset time, and the first water spraying time is continued; the third preset time is longer than the fourth preset time, that is, when the drainage pump drains water, and after a certain time, the spray head starts spraying water. Since the water level is high at the initial stage of water discharge, water resources for water discharge are wasted if water discharge and water discharge are performed simultaneously. After waiting for a certain time for drainage, the water level can be reduced, only a little detergent foam remains on the door glass correspondingly, and water resources can be saved to the greatest extent by spraying water at the moment, and a good foam eliminating effect is achieved.

S800, when the rinsing and dewatering stage is detected to enter, setting a first stop time for the drainage pump to stop after working for a third preset time;

when the rinsing and dewatering stage is completed, the drum is required to dewater the clothes inside the drum, water in the clothes flows out, the drainage pump works for the same time and is stopped for the first stop time after the third preset time, and the water can be drained better.

S900, judging the dehydration rotating speed of the roller, and controlling the spray head to start water spraying and continue for a first water spraying time when the rotating speed of the roller is less than or equal to a second preset rotating speed;

based on the above embodiments, since the detergent remains in the laundry during the rinsing stage, and the drum has a high rotation speed during the dewatering, the detergent in the laundry is thrown out to the door glass to form detergent bubbles. Therefore, detergent foam on the door glass needs to be removed, but at the moment, the rotating speed of the roller is higher because the roller is in a dehydration state, and if the rotating speed of the roller is less than or equal to a second preset rotating speed, the spray head is controlled to start spraying water and continue spraying water for a first time. When the rotating speed of the roller is greater than the second preset rotating speed, the spray head stops spraying water, the roller at the moment has higher rotating speed, and if the spray head sprays water, water flow can be dragged by the roller to form a ring shape, so that the water flow cannot be uniformly sprayed on the door glass, and detergent foam on the door glass cannot be well removed. Therefore, the rotation speed of the drum needs to be detected so as to judge whether the spray head needs to spray water during dewatering.

If there are a plurality of rinsing stages, the above rinsing water-in to rinsing water-out stages are repeated.

In an embodiment, the first predetermined time is 45 seconds, the first stop time is 5 seconds, and the second predetermined time is 10 seconds, so that the first predetermined time is greater than the second predetermined time, that is, when the drainage pump drains water, and after a certain time elapses, the spray head starts spraying water. The first water spraying time is 10 seconds, detergent foam can be better clear through the appropriate first water spraying time, water resources are saved, the first water spraying time can be flexibly changed according to the detergent foam amount in actual use, furthermore, the first preset rotating speed is 600RPM (revolutions per minute), whether the spray head needs to spray water can be judged according to the appropriate first preset rotating speed, therefore, the first preset rotating speed is not suitable to be set too high, and otherwise, the foam removing effect is not good.

The following description is made with reference to specific usage scenarios:

the method comprises the following steps: when the main washing stage is finished and the main washing drainage stage is entered, setting the drainage pump to be stationary for 5 seconds after working for 45 seconds;

step two: when the drainage pump starts to work and lasts for 10 seconds, controlling the spray head to spray water and continuing for 10 seconds;

step three: when the main washing dehydration stage is detected, setting the drainage pump to work for 45 seconds and then stand still for 5 seconds;

step four: judging the dehydration rotating speed of the drum, and controlling the spray head to spray water for 10 seconds when the rotating speed of the drum is less than or equal to 600 RPM;

in another embodiment, the second spraying time is 20 seconds, the third preset time is 50 seconds, and the fourth preset time is 15 seconds. In the rinsing stage, because the clothes are mainly rinsed completely and a large amount of water is needed, a large amount of detergent foam is also caused, and the second water spraying time is set to be 20 seconds, so that the door glass can be washed for a long time, and the generation of the detergent foam is avoided; the third preset time is set to 50 seconds (more than between the first preset times) so that the water in the drum can be drained. Correspondingly, the fourth preset time is longer than the second preset time, so that the detergent foam on the door glass can be better removed by matching with the third preset time. Further, the second preset rotating speed is 550RPM, and whether the spray head needs to spray water can be judged according to the appropriate second preset rotating speed, so that the second preset rotating speed is not suitable to be set too high, otherwise, the foam removing effect is not good.

The following description is made with reference to specific usage scenarios:

step five: when the rinsing water inlet stage is started, controlling the spray head to spray water for 20 seconds;

step six: when the rinsing and water discharging stage is detected to be entered, setting the drainage pump to be static for 5 seconds after working for 50 seconds;

step seven: when the drainage pump starts to work and lasts for 15 seconds, controlling the spray head to spray water and continuing for 10 seconds;

step eight: when the rinsing and dewatering stage is detected to enter, setting the drainage pump to work for 50 seconds and then to stand for 5 seconds;

step nine: judging the dewatering rotation speed of the drum, and controlling the spray head to spray water for 10 seconds when the rotation speed of the drum is less than or equal to 550RPM.

Therefore, the washing machine door glass is sprayed with water in the drainage stage and the dehydration stage of the washing machine, so that detergent foam and scraps remained on the door glass can be washed away, and dirt is prevented from remaining on the door glass.
