With the advancement of science and technology, the automation level of human life is getting higher and higher, and the daily housework is gradually replaced by machines from manpower. As a household appliance commonly used in daily life, washing equipment has brought great convenience to people's lives. Washing equipment is classified according to the washing method, and can be roughly divided into pulsator washing machines and drum washing machines. Take the pulsator washing machine as an example. During the operation of the pulsator washing machine, when there is too much detergent or high-foaming detergent is used, the detergent is stirred and impacted by water flow, and a large amount of foam is easily generated. In order to remove a large amount of foam. Cleaning requires a lot of water, which increases the power consumption of the washing machine and greatly affects user satisfaction.

In order to improve the defoaming effect of the pulsator washing machine, the existing pulsator washing machine adds a spray rinsing step in the control program, that is, after the dehydration operation, the inner tub is controlled to rotate, and the washing water is sprayed on the clothes in a spray manner. Rinse, wash away the foam on the clothes, and at the same time open the drain valve, the foam on the clothes will be discharged with the washing water sprayed on the clothes, which not only achieves the purpose of eliminating foam, but also achieves the purpose of rinsing clothes with water saving. . However, after the dehydration operation, some clothes (such as children's clothes, socks, underwear and other small clothes) will stick to the inner wall of the inner tub due to centrifugal action, because the spray range of the washing water does not cover the inner wall of the inner tub. Therefore, it is difficult for the washing water to be sprayed onto the part of the clothing, and the part of the clothing cannot be sprayed and rinsed, thereby reducing the washing effect of the spraying and rinsing, and greatly affecting the user's experience.

Therefore, there is a need in the art for a new control method for washing equipment to solve the above problems.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention. For example, although this application is described in conjunction with a pulsator washing machine, the technical solution of the present invention is not limited to this, and the control method can obviously also be applied to other similar washing equipment such as washing and drying machines, shoe washing machines, etc. Such changes do not depart from the principle and scope of the present invention.

Based on the technical problems raised in the background art, the present invention provides a control method for a pulsator washing machine, which aims to determine whether to make the pulsator washing machine directly perform the spray rinsing operation according to the weight of the object to be cleaned, so as to avoid the need for cleaning. The weight of the object is light, and the object to be cleaned will be directly sprayed and rinsed under the condition that the object to be cleaned will be attached to the inner wall of the inner tub due to the centrifugal effect, which improves the effect of spraying and rinsing of the pulsator washing machine, saves water resources, and improves the efficiency of the washing machine. user experience.

Referring to FIG. 1 and FIG. 2, FIG. 1 is a flowchart of a control method of the present invention; FIG. 2 is a flowchart of a control method of an embodiment of the present invention. As shown in Figure 1, the control method of the present invention comprises the following steps:

S1. Obtain the weight of the object to be cleaned;

S2. According to the weight, determine whether to make the pulsator washing machine directly perform the spray rinsing operation.

It should be further explained that in the process of spray rinsing, the rotation of the inner barrel is controlled, the washing water is sprayed onto the clothes to rinse the clothes, the foam on the clothes is washed away, and the drain valve is opened at the same time. The foam on the laundry is drained with the wash water sprayed onto the laundry.

In a preferred embodiment, in the above step S2, the step of "judging whether to make the pulsator washing machine directly perform the spray rinsing operation according to the weight" specifically includes:

S21, judging whether the weight is greater than a preset weight threshold;

S24, after the shaking and scattering operation, make the pulsator washing machine perform a spray rinsing operation.

Specifically, in step S22, if the weight is greater than the preset weight threshold, it means that the weight of the object to be cleaned is relatively heavy. After the dehydration operation, all the objects to be cleaned are gathered at the bottom of the inner tub. The rotation of the inner tub enables the spray range of the washing water to cover the bottom of the inner tub, and the washing water can be sprayed on all the objects to be cleaned, so that the pulsator washing machine directly performs the spray rinsing operation to wash away the foam on the objects to be cleaned. It not only achieves the purpose of eliminating foam, but also achieves the purpose of saving water and rinsing the objects to be cleaned.

Further, in step S23, if the weight is less than or equal to the preset weight threshold, it means that the weight of the object to be cleaned is relatively light. ) will be attached to the inner side wall of the inner tub due to centrifugal action. Since the spray range of the washing water does not cover the inner side wall of the inner tub, it is difficult for the washing water to be sprayed on this part of the clothes, and the part of the clothes cannot be sprayed and rinsed. , in order to improve the effect of spraying and rinsing, the pulsator washing machine is made to perform the shake-scattering operation, which is the object to be cleaned on the inner side wall of the object to be cleaned that is attached to the inner side wall of the barrel. After the shake-scattering operation, the pulsator is When the washing machine performs the spray rinsing operation, the washing water can be sprayed onto all the objects to be cleaned, thereby improving the spray rinsing effect of the pulsator washing machine, and thus improving the user experience.

In the above process, through the setting of the preset weight threshold, a conclusion is given for judging whether the pulsator washing machine directly performs the spray rinsing operation. Wherein, the preset weight threshold may be the minimum weight at which the object to be cleaned will not stick to the inner side wall of the inner tub due to centrifugal action. Of course, the preset weight threshold is not limited to the above-mentioned weight, and can also be other weights, such as the weight obtained by those skilled in the art according to experiments under specific working conditions, or the empirical weight obtained according to experience, as long as the preset weight is satisfied The demarcation point determined by the weight threshold can meet the requirements of judging whether the pulsator washing machine directly performs the spray rinsing operation.

It can also be quickly and evenly distributed under the action of the washing water; in step S232, during the drainage operation, the objects to be cleaned will all fall to the bottom of the inner tub along with the water flow. If the spray rinsing operation is performed later, the washing water It can be sprayed on all the objects to be cleaned, thereby improving the spraying and rinsing effect of the pulsator washing machine, and thus improving the user experience.

S2311. Obtain the preset water level threshold of the pulsator washing machine;

S2312: Make the pulsator washing machine perform a water filling operation according to a preset water level threshold.

Specifically, in step S2312, the pulsator washing machine is made to perform the water injection operation according to the preset water level threshold, and the objects to be cleaned attached to the inner wall of the inner tub float in the washing water under the action of the injected washing water, and the objects to be cleaned floating in the water Under the action of the injected washing water, the cleaning objects can also be quickly and evenly distributed, and then the operations such as drainage and spray rinsing are performed, which improves the effect of the spray rinsing of the pulsator washing machine, thereby improving the user experience.

In order to reduce the consumption of washing water, in the above step S2312, the step of "making the pulsator washing machine perform the water filling operation according to the preset water level threshold" specifically includes:

The value of the difference between the water level threshold and the water injection water level is set, no matter what value is adopted, as long as the water injection water level can be made smaller than the preset water level threshold.

In order to better distribute the clothes in the inner tub evenly, the control method further includes:

S2313 , after the pulsator washing machine performs the water filling operation, make the inner tub rotate continuously at a speed lower than the normal washing speed.

Specifically, in step S2313, the inner tub is continuously rotated at a speed lower than the normal washing rotation speed, on the one hand, the rotation speed of the washing tub is reduced to avoid splashing of the washing water injected into the inner tub; The water inside is pre-balanced, so that the water injected into the inner barrel can be quickly and evenly distributed in the inner barrel, and the objects to be cleaned attached to the inner wall of the inner barrel float in the washing water under the action of the injected washing water, The objects to be cleaned in the inner tub can also be quickly and evenly distributed under the action of the flowing water flow, which improves the speed of evenly distributing the objects to be cleaned in the inner tub, shortens the time for balance correction of the pulsator washing machine, and improves the balance of the pulsator washing machine. The effect of the correction, thereby improving the user experience.

Of course, it is also possible to make the inner tub rotate continuously at a speed lower than the normal washing speed during the water filling operation of the pulsator washing machine; or to make the inner tub rotate at a speed lower than the normal washing speed during the water filling operation of the pulsator washing machine. The speed is intermittently rotated; or after the pulsator washing machine performs the water filling operation, the inner tub is intermittently rotated at a speed lower than the normal washing speed. Those skilled in the art can flexibly adjust and set the rotation mode of the inner tub in practical applications. This rotation mode is sufficient as long as the objects to be cleaned attached to the inner side wall of the inner tub can float in the washing water under the action of the injected washing water.

It should be further explained that after the pulsator washing machine performs the water filling operation, the inner tub is continuously rotated at a speed lower than the normal washing rotation speed, and the speed lower than the normal washing rotation speed is obtained by those skilled in the art according to experiments under specific working conditions. The experimental rotation speed, or the empirical rotation speed obtained from experience, can meet the requirements of effective balance correction at this rotation speed. After repeated experiments, observations, analysis and comparison by the inventor, preferably, the speed lower than the normal washing speed is 90 rpm.

In order to drop all the objects to be cleaned to the bottom of the inner tub, the step of "making the pulsator washing machine perform a draining operation" in the above step S232 specifically includes:

S2321. After the inner tub is continuously rotated at a speed lower than the normal washing rotation speed, make the pulsator washing machine perform a draining operation.
