As shown in Figures 1 and 2, the present invention provides a control method for a washing machine. The washing machine is provided with a clothes putting opening, and a pre-wash basin that can be flipped and opened and closed is installed at the clothes putting opening. The washing machine uses the pre-wash basin. After pre-washing the clothes, control the pre-wash basin to open the clothes putting port, pour the clothes into the washing machine, and clean the clothes;

In the embodiment of the present invention, the clothes are pre-washed in the pre-wash basin, and the pre-washed clothes are poured into the washing machine, and then the washing machine cleans the clothes, thus realizing the pre-washing of the clothes before cleaning. It improves the cleaning effect of clothes and enhances the user experience.

The cleaning work of the washing machine includes at least one stage of water inlet, washing, rinsing, dehydration, and drying; the pre-wash basin pours the clothes into the washing machine, and the washing machine can wash, rinse, dehydrate, and dry the clothes. At least one of dry, for example, a shirt only has stains on the collar part, and other parts are free of stains. Therefore, after washing the collar part of the shirt with detergent and rinsing the washed shirt collar part with pure water, pre-wash Pour the shirts into the washing machine, and the washing machine can dehydrate the shirts directly.

As shown in Figure 1, in the embodiment of the present invention, after pre-washing the clothes, if the washing machine is working, the washing machine will first stop working. After the pre-wash basin opens the clothes putting opening and pours clothes into the washing machine, the washing machine will continue to work. .

In the embodiment of the present invention, after pre-washing the clothes, it is determined whether the washing machine is working. The work includes at least one of washing, rinsing, dehydration, and drying. If the washing machine is working, especially the pulsator washing machine, open the The clothes put-in port of the washing machine that is working will cause the clothes or washing water in the washing machine to splash out from the clothes put-in port, affecting the washing of clothes. Therefore, the washing machine can stop working first, open the pre-wash basin and open the clothes put-in port. After the clothes are poured into the washing machine, the washing machine continues to work; for example, the pulsator washing machine is washing and the washing water is stirred. If the clothes putting opening is opened, the washing water will splash out from the clothes putting opening.

In addition, after pre-washing the clothes, if the washing machine is working, the washing machine will continue to work until the end of this stage of work, then the washing machine will stop working, then open the clothes putting port, pour the clothes into the pre-wash basin, and then the washing machine will continue to work. proceed with the next phase of work;

For example, only the collar part of a shirt has stains, and the other parts are free of stains. Therefore, after washing the collar part of the shirt with detergent, the collar part of the shirt has been washed relatively clean. Pour the clothes into the washing machine in the pre-wash basin. The shirt can be rinsed directly without further washing. Therefore, after pre-washing the shirt, if the washing machine is in the washing phase, wait until the washing machine completes the washing phase, then the washing machine will stop working, and then pour the shirt into the pre-wash basin. , the washing machine enters the rinsing stage and rinses the shirt.

As shown in Figure 1, in the embodiment of the present invention, before opening the clothes putting port, if there are clothes in the washing machine, it is determined whether the clothes in the pre-wash basin can be mixed with the clothes in the washing machine. If not, the pre-wash is taken out first. After washing the clothes in the basin, open the clothes put-in port, take out the clothes in the washing machine, and then pre-wash the basin and pour the clothes into the washing machine.

In the embodiment of the present invention, after pre-washing the clothes, method one: if the washing machine is working, there are clothes in the washing machine, and the clothes in the washing machine and the clothes in the pre-wash basin cannot be washed together, the washing machine will stop working and take out the clothes first. Pre-wash the clothes in the basin, then open the clothes input port, take out the clothes in the washing machine, then pre-wash the basin and pour the clothes into the washing machine;

Method 2: If the washing machine is working, there are clothes in the washing machine, and the clothes in the washing machine and the clothes in the pre-wash basin can be washed together, open the clothes input port, pour the clothes into the pre-wash basin into the washing machine;

Method 3: If the washing machine is not working, there are clothes in the washing machine, and the clothes in the washing machine and the clothes in the pre-wash basin cannot be washed together, take out the clothes in the pre-wash basin first, then open the clothes put-in port and take out the clothes in the washing machine. , and then pour the clothes into the washing machine in the pre-wash basin;

Method 4: If the washing machine is not working, there are clothes in the washing machine, and the clothes in the washing machine and the clothes in the pre-wash basin can be washed together, open the clothes input port, pour the clothes into the pre-wash basin into the washing machine;

Method 5: Regardless of whether the washing machine is working or not, if there is no clothes in the washing machine, open the clothes input port, pre-wash basin and pour clothes into the washing machine.

If the operating parameters of the washing machine do not meet the requirements for cleaning the clothes in the pre-wash basin, you can wait until the washing machine completes cleaning of the clothes, first take out the clothes in the pre-wash basin and move them to other places, then rotate the pre-wash basin to open the clothes input port and take out the clothes in the washing machine. clothes, and then put the clothes into the pre-wash basin, and the pre-wash basin pours the clothes into the washing machine; or, because the clothes in the pre-wash basin are urgently needed, the washing machine can immediately stop washing the clothes, and first take out the clothes in the pre-wash basin to Elsewhere, rotate the pre-wash basin to open the clothes insertion port, take out the clothes in the washing machine, then put the clothes into the pre-wash basin, and the pre-wash basin pours the clothes into the washing machine.

For example, at least one of the clothes in the pre-wash basin and the clothes in the washing machine is easy to fade. In order to prevent the two clothes from staining each other and passing colors, the two clothes cannot be washed together, especially the two clothes cannot be washed together. Wash and rinse.

Further, if the clothes in the pre-wash basin can be mixed with the clothes in the washing machine, it is judged whether the operating parameters of the washing machine can meet the requirements for cleaning the clothes in the pre-wash basin. If not, first take out the clothes in the pre-wash basin, and then Open the clothes input port, take out the clothes in the washing machine, and then pour the clothes into the washing machine in the pre-wash basin.

For example, during the washing phase of the washing machine, the working parameters of the washing machine include motor speed. There is no dyeing problem for the clothes in the pre-wash basin and the clothes in the washing machine. However, if the material of the clothes in the pre-wash basin is cotton and linen, the clothes in the washing machine will not be dyed. The material is chiffon. Since cotton and linen will have serious wrinkles when washed at a higher motor speed, when the washing stage with a higher motor speed is not suitable for the clothes in the pre-wash basin, you can wait until the clothes in the washing machine are washed. , first take out the clothes in the pre-wash basin, then open the clothes insertion port, take out the clothes in the washing machine, and then pour the clothes into the pre-wash basin into the washing machine.

As shown in Figure 2, in the embodiment of the present invention, the washing machine uses the pre-wash basin to perform the water inlet operation when pre-washing the clothes. When the washing machine receives the pre-wash instruction, it determines whether the pre-wash basin has closed the clothes putting opening. If so, Then add pre-wash water into the pre-wash basin.

In the embodiment of the present invention, only when the clothes putting opening is in a closed state, can the pre-wash water be fed into the pre-wash basin, and the clothes can be pre-washed. If the clothes putting opening is not in a closed state, water can be fed into the pre-wash basin, The flipping of the pre-wash basin causes water to splash everywhere, resulting in a waste of wash water;

The pre-wash basin pre-washes the clothes. For example, the user can pre-wash the clothes by filling in water. The user puts the clothes into the pre-wash basin. The user can manually apply laundry detergent to certain parts of the clothes and use pre-wash. The water in the basin is manually scrubbed, so that pre-washing can be achieved to meet user needs.

Furthermore, when the washing machine is working, the pre-wash basin always closes the clothes putting opening, then water can be fed into the pre-wash basin; when the washing machine is not working, if the pre-wash basin has the clothes putting opening closed, water can be fed into the pre-wash basin. , when the washing machine is not working, if the pre-wash basin does not close the clothes putting opening, close the clothes putting opening first, and then fill the pre-wash basin with water.

As shown in Figure 2, in the embodiment of the present invention, when the washing machine is working, the washing machine can first pause the operation during the process of filling the pre-wash basin with water, and then continue to operate after stopping the water feeding into the pre-wash basin; Or, the washing machine keeps working.

In the embodiment of the present invention, for example, when the washing machine needs to perform the dehydration stage, the dehydration speed of the washing machine in the dehydration stage is relatively large, causing the washing machine to vibrate greatly, and the washing machine is not stable enough. In particular, the clothes in the washing machine are entangled, causing the washing machine to vibrate greatly. Therefore, , in order to prevent the vibration of the washing machine from causing the water in the pre-wash basin to vibrate and splash, you can choose to pause the washing machine when water is poured into the pre-wash basin;

For another example, in order to avoid wrinkles on the shirt during the dehydration stage of the washing machine, the washing machine only performs the washing stage and the rinsing stage and does not perform the dehydration stage. Also, because the shirt is made of cotton and linen, the washing speed and rinsing speed of the washing machine are relatively small. Therefore, the washing machine Water can be fed into the pre-wash basin during continuous operation.

In the embodiment of the present invention, when the washing machine is working and in the process of feeding water into the pre-wash basin, if it is necessary to open the clothes putting port, first stop feeding water into the pre-wash basin and move the water out of the pre-wash basin. Then open the clothes insertion opening.

In the embodiment of the present invention, for example, when the washing machine is working and water is being poured into the pre-wash basin, if the washing machine makes a sound of hitting the inner barrel of the washing machine during the washing stage, and the sound is relatively loud, it is necessary to open the clothes putting port and open the inner barrel of the washing machine. Check inside to see if there are any foreign objects in the inner barrel. Therefore, in order to solve the above problem, you need to stop the water flow into the pre-wash basin and move the water out of the pre-wash basin to other places. Then open the clothes put-in port and solve the above problems. After the above problem is solved, close the clothes discharge port of the pre-wash basin and then fill the water into the pre-wash basin again.

As shown in Figure 2, in the embodiment of the present invention, before water is poured into the pre-wash basin, if there are clothes in the washing machine, it is determined whether the clothes in the pre-wash basin can be mixed with the clothes in the washing machine. If not, Then do not fill the pre-wash basin with water. Take out the clothes in the washing machine first, and then fill the pre-wash basin with water.

In the embodiment of the present invention, before water is poured into the pre-wash basin, method one: if there are clothes in the washing machine and the clothes in the pre-wash basin cannot be mixed with the clothes in the washing machine, no water is poured into the pre-wash basin. water, first take out the clothes in the washing machine, and then fill the pre-wash basin with water;

Since the two kinds of clothes cannot be washed together, in order to open the clothes put-in port and prevent water from entering the pre-wash basin, and then take out the water in the pre-wash basin to other places and avoid excessive use of manpower, the only way to do this is to put the clothes in the washing machine. After taking out the clothes, pour water into the pre-wash basin.

Method 2: If there are clothes in the washing machine and the clothes in the pre-wash basin can be mixed with the clothes in the washing machine, water can be poured into the pre-wash basin.

As shown in Figures 3-8, the present invention also provides a washing machine that adopts the above control method. The washing machine includes a washing machine body.

The upper cover 2 is provided with a second put-in port 21. The second put-in port 21 can be used to put clothes or water into the inner bucket. Specifically, the clothes or washing water pass through the second put-in port 21, the first put-in port 111 and the inner bucket mouth in sequence. into the inner bucket; the second put-in port 21 is equipped with a pre-wash basin 3 that opens and closes the second put-in port 21. The pre-wash basin 3 opens the second put-in port 21, and the clothes in the pre-wash basin 3 can be turned over. Either the wash water is transferred into the inner bucket through the second putting port 21, the first putting port 111 and the inner bucket mouth, or the second putting port 21 is opened by turning over the pre-wash basin 3, so that the clothes in the non-pre-wash basin 3 or The wash water is transferred into the inner bucket through the second putting port 21, the first putting port 111 and the inner bucket mouth; the pre-wash basin 3 closes the second putting port 21, so that the second putting port 21 is closed, and the upper cover 2 closes the first putting port. 111 at the same time, the pre-wash basin 3 closes the second put-in port 21 to prevent the washing water in the inner bucket from splashing, and at the same time, the clothes can be pre-washed in the pre-wash basin 3; or, the upper cover 2 opens the first put-in port 111. At the same time, the pre-wash basin 3 closes the second injection port 21. In addition, a reversible pre-wash basin 3 can also be installed at the first injection port 111 .

A pre-wash basin 3 is provided in the second putting port 21 to open and close the second putting port 21, so that the washing machine has three states, as shown in Figure 3. The first state is that the upper cover 2 covers the first putting port 111. The pre-wash basin 3 covers the second putting port 21. The first state can be used for washing, rinsing, dehydration in the washing machine, and pre-washing of clothes in the water basin. As shown in Figure 4, the second state is for the upper cover 2 to be covered.
