Technical Field

The invention belongs to the technical field of shoe washing, and particularly relates to a control method of a shoe washing machine and the shoe washing machine.

Background

The shoes are one of clothes with high use frequency, and the shoes are easy to smell due to the sealing property of the environment when being worn, so that the shoes need to be brushed. As one of the current more common shoe brushing devices, in order to meet the more and more general demand of people for cleaning shoes, shoe washing machines appear on the market, and the shoe washing machine is the key point of user attention to the cleaning effect of shoes. However, the conventional shoe washing machine is not ideal in the effect of washing shoes due to limitations of its structure, washing principle, etc.

The current shoe washing machine that uses comparatively extensively directly increases the brush or increases the brush on the inner wall on impeller washing machine's basis, relies on rivers drive shoes and brush relative motion when the impeller rotates to realize cleaning shoes. Moreover, the shoe washing mode is suitable for washing the same pair of shoes at a time or a plurality of pairs of shoes with similar sizes. If wash many two different shoes of size simultaneously, then can appear that the shoes that the size is little float on the surface of water because the size difference of shoes, and the condition that the shoes that the size is big sink at the bottom influences the washing effect. In addition, although the shoe washing mode can bring the shoe to the position near the brush by means of water flow, the shoe can be uninterruptedly close to and far away from the brush due to impact under the action of the water flow, namely, the water flow cannot continuously apply enough acting force to enable the brush and the shoe to continuously and fully rub with each other, so that the interaction force between the brush and the shoe is small, and the cleaning effect is limited.

Based on this, the applicant improved the shoe washing machine in the application document with the application number of 202110368915.8, but the control method of the improved shoe washing machine is still deficient, so a new scheme is proposed here to make the improved shoe washing machine more perfect in the control method and achieve better shoe washing effect.

Through the arrangement mode, the shoe washing machine can wash the same pair of shoes or a plurality of pairs of shoes with similar sizes at one time like the shoe washing machine in the prior art, and can also achieve the effect of washing shoes with different sizes at the same time by adjusting the height of the liquid level in the washing barrel and adopting a higher rotation-stop ratio along with the rise of the liquid level. When the liquid level in the washing barrel is low, the shoes with small sizes can turn over more frequently in a large range under the action of the ball brush when the liquid level is low, and the shoes with large sizes have smaller turning ranges and frequency due to the small sizes of the shoes and the low liquid level when the ball brush acts, so that the washing force of the shoes with small sizes is larger than that of the shoes with large sizes; and the liquid level risees the back, because the less shoes of size can float on the surface of water, for the great shoes of size, the less shoes of size are relatively weaker owing to keep away from the washing dynamics that the ball brush received, and because the rising of liquid level, the great shoes of size have had bigger upset space, and the commentaries on classics that improves stops than also can promote the great shoes of size the upset effect and with the effect of the friction washing of ball brush for the great shoes of size have received the bigger washing dynamics than the less shoes of size. When the rotation-stop ratio is increased, the water flow is increased, and the phenomenon that the shoes with large sizes are clamped can be well avoided. Therefore, the shoe washing machine can achieve a better washing effect by adopting the control method, shoes with different sizes can be washed once, the situation that part of the shoes are excessively washed and even worn can not occur, the shoes do not need to be distinguished according to different sizes before washing every time, and the shoe washing experience of users is obviously improved.

The washing tub 1 is also fixedly provided with a thread scraps filter 4, and the shoe washing machine further comprises a sterilization part (not shown in the figure), wherein the sterilization part can adopt an ultraviolet device and a heater.

The control method of the shoe washing machine of the present invention will be explained.

As shown in fig. 2, the control method includes the steps of:

s1, controlling the washing barrel 1 to feed water until the liquid level is the first height, and controlling the washing part 3 to rotate at the first rotation-stop ratio for the first time.

The first height is the top height of the ball brush 31. The rotation-stop ratio is the ratio of the rotation time and the stop time of the washing part 3, the first rotation-stop ratio is 1, and specifically can be 0.5/0.5, that is, the washing part 3 can rotate clockwise for 0.5 second and then stop for 0.5 second, and then rotate counterclockwise for 0.5 second and then stop for 0.5 second. Of course, the brushing part 3 may be rotated counterclockwise for 0.5 second and then stopped for 0.5 second, and then rotated clockwise for 0.5 second and then stopped for 0.5 second. The first time period may be 3 minutes.

And S2, controlling the washing barrel 1 to continuously feed water until the liquid level is at the second height, and controlling the washing part 3 to rotate at the second rotation-stop ratio for a second time.

The second height is greater than the first height by a value that is half the sum of the first height and the height of the top of the lint filter 4. The second rotation-stop ratio is greater than the first rotation-stop ratio, and the second rotation-stop ratio is 4. Specifically, it may be 2/0.5, that is, the washing part 3 may rotate clockwise for 2 seconds and then stop for 0.5 seconds, and then rotate counterclockwise for 2 seconds and then stop for 0.5 seconds. Of course, the washing part 3 may be rotated counterclockwise for 2 seconds and then stopped for 0.5 seconds, and then rotated clockwise for 2 seconds and then stopped for 0.5 seconds. The second time period may be 5 minutes.

S3, controlling the washing barrel 1 to continue to feed water until the liquid level is at the third height, and controlling the washing part 3 to rotate at the third rotation-stop ratio for a third time.

The value of the third height is greater than the value of the second height, the third height being the height of the top of the lint filter 4. The third rotation-stop ratio is greater than the second rotation-stop ratio, and the third rotation-stop ratio is 8. Specifically, it may be 4/0.5, that is, the washing part 3 may rotate clockwise for 4 seconds and then stop for 0.5 seconds, and then rotate counterclockwise for 4 seconds and then stop for 0.5 seconds. Of course, the washing part 3 may be rotated counterclockwise for 4 seconds and then stopped for 0.5 seconds, and then rotated clockwise for 4 seconds and then stopped for 0.5 seconds. The third time period may be 10 minutes.

S4, after washing, controlling the washing tub 1 to discharge water.

The water in the washing tub 1 can be naturally discharged by gravity, or can be pumped out by a pump body (not shown in the figure) or the like, so that the drainage progress is accelerated.

And S5, sterilizing the shoes in the washing tub 1 by the sterilizing part.

Wherein, the rotation speed of the washing part 3 is the same in the process of stable rotation. In this embodiment, the positions of the first height, the second height and the third height may be determined by a liquid level sensor (not shown) during the process of water inlet of the washing tub 1. And the shoe washing machine in this embodiment is also configured to be able to perform the above-described control method.

It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention, and therefore, all of them will fall into the protection scope of the present invention.

For example, in an alternative embodiment, considering that the shoes generate little or no lint during the washing process, the lint filter may not be provided, but the third height may be set to a height of the liquid level when about 70% of the water is contained in the washing tub.

For example, in another alternative embodiment, the sterilization part may employ only one of the ultraviolet device and the heater (not shown in the drawings) for the sake of cost and installation space.

For example, in another alternative embodiment, the height of the liquid level can be determined by combining the image collector with the image identifier (not shown in the figure).

For example, in another alternative embodiment, the ball brush 31 may be provided in plural, and in addition to providing the ball brush 31 at the center of the pulsator 32, a plurality of ball brushes 31 (not shown) may be provided at a non-center position of the pulsator 32.

For example, in another alternative embodiment, the ball brush 31 may not be disposed at the center of the pulsator 32, and a plurality of ball brushes 31 (not shown) may be disposed at non-center positions of the pulsator 32.

For example, in another alternative embodiment, the connection relationship between the ball brush 31 and the pulsator 32 may be detachable, such as snap-fit connection, or bolt connection. In actual washing, different ball brushes 31 can be flexibly selected according to different conditions of shoes. When the shoes are soft, the soft ball brush can be replaced for washing. For some shoes made of hard materials, a hard ball brush can be selected for washing.

For example, in an alternative embodiment, a removable connection between the brush member 312 and the base 311 may be provided to facilitate thorough and complete cleaning of the brush member 312.

For example, in another alternative embodiment, the brush member 312 may have other shapes such as a rectangular parallelepiped (not shown).

For example, in an alternative embodiment, the brush member 312 may be made of polypropylene, so that the brush member 312 has good stability.

For example, in another alternative embodiment, the rotation speed of the washing brush unit 3 during the steady rotation may be different in the three steps S1 to S3. For example, the rotation speed of the washing part 3 may be the minimum in step S1, the rotation speed of the washing part 3 may be greater than the rotation speed in step S1 in step S2, and the rotation speed of the washing part 3 may be the maximum in step S3.

For example, in another alternative embodiment, in step S1, the rotation time and the stop time of the washing part 3 may be adjusted as long as the first rotation-stop ratio is 1, for example, 0.8/0.8, etc.

For example, in another alternative embodiment, in step S1, the first rotation-stop ratio may also be adjusted based on the fact that the first rotation-stop ratio is smaller than the second rotation-stop ratio, for example, the first rotation-stop ratio may be 1.5.

For example, in another alternative embodiment, in step S2, the rotation time and the stop time of the washing brush 3 may be adjusted as long as the second rotation/stop ratio is 4, for example, 3.6/0.9.

For example, in another alternative embodiment, in step S2, the second rotation-stop ratio may also be adjusted based on the fact that the second rotation-stop ratio is smaller than the third rotation-stop ratio, for example, the second rotation-stop ratio may be 4.5.

For example, in another alternative embodiment, in step S3, the rotation time and the stop time of the washing brush 3 may be adjusted as long as the third rotation/stop ratio is 8, for example, 4.8/0.6.

For example, in another alternative embodiment, in step S3, the third rotation-stop ratio may also be adjusted based on the fact that the third rotation-stop ratio is greater than the second rotation-stop ratio, for example, the third rotation-stop ratio may be 8.8.

For example, in another alternative embodiment, the determination of the positions of the first height, the second height and the third height may further be based on the determination of the volume of the washing tub 1 and the values of the first height, the second height and the third height, and the amount of water required for the liquid in the washing tub 1 to reach the corresponding first height, second height and third height is obtained by calculation, and the height of the liquid level is controlled by controlling the amount of water to be fed.

For example, in another alternative embodiment, step S3 may not be performed, and shoes can be washed only by steps S1 and S2, so that certain shoe washing effect can be obtained, and shoes with different sizes can be washed at the same time. When the shoes to be washed are all small-sized shoes, it is generally sufficient to perform the washing only by performing the steps S1 and S2.

In summary, the control method of the shoe washing machine of the present invention is suitable for the specific washing machine, i.e. the ball brush type shoe washing machine, related to the present invention. The shoe washing machine not only can wash the same pair of shoes or a plurality of pairs of shoes with similar sizes at one time like the shoe washing machine in the prior art, but also can adjust the height of the liquid level in the washing barrel and adopt higher rotation-stop ratio along with the rise of the liquid level so as to wash a plurality of pairs of shoes with different sizes. Shoes with smaller sizes are lighter in weight, smaller in length and width and easy to float on the water surface. The shoes with larger size are heavier, have larger length and width and are easy to sink on the water bottom.

When just beginning to wash, to the logical water in the washtub 1 for the liquid level height reaches first height, and the liquid level is lower this moment, can make the less shoes of size can appear the great and more frequent upset of range under the effect of ball brush when the liquid level height is lower, and the bigger shoes of size then because the reason of self size and liquid level are lower, the range and the frequency of upset are less when the ball brush is used, make the washing dynamics of the less shoes of size bigger for the bigger shoes of size bigger.

Then, water is continuously introduced into the washing barrel 1, so that the liquid level reaches a second height, the width of the liquid level, which is far away from the top of the ball brush, is enough to accommodate at least one shoe to roll, at this time, the shoes with smaller sizes float on the water surface along with the rise of the liquid level, but the rotation of the impeller 32 is influenced by the poking blades arranged on the impeller 32, the water flow close to the side of the washing barrel 1 rotates, the rotation influence on the water at the center of the impeller 32 is smaller, when the impeller rotates in the same direction, a vortex is formed at the center of the washing barrel 1, so that the shoes with smaller sizes are washed by the vortex belt to be washed by the ball brush again, and therefore, in the washing stage, the washing force on the shoes with smaller sizes is weakened, and the shoes can still be washed to a certain degree. And because the rising of liquid level, the great shoes of size have had bigger upset space, and this moment for before and the commentaries on classics that improves stop than also can promote the upset effect of the great shoes of size and with the effect of the friction washing of ball brush, at this washing stage for the great shoes of size have received the bigger washing dynamics of the less shoes of specific size.

When water enters to the third height, the liquid level is higher, the small-sized shoes float on the water surface, the received washing force is smaller, and the large-sized shoes still receive larger washing force under the action of the higher third rotation-stop ratio of the ball brush due to the size influence of the shoes. The shoes with the small size can be prevented from being excessively washed to cause abrasion, and meanwhile, the condition that the shoes with the large size are not sufficiently washed can be avoided.

Therefore, the shoe washing machine can achieve a better washing effect by adopting the control method, can wash more shoes with different sizes at one time, and can not cause the condition that the shoes with smaller sizes are excessively washed or even worn, nor cause the condition that the shoes with larger sizes are not washed cleanly.

In addition, the conventional cylindrical brush type shoe washing machine is difficult to release by adjusting the rotation/stop ratio once the shoes are stuck, and is easily damaged by an excessive force even if the shoes are released. The ball brush type shoe washing machine mainly washes shoes through the ball brush, no obstacle is arranged above the ball brush, the ball brush rotates forwards and reversely periodically, when the rotation-stop ratio is increased, water flow is increased, the water level heights corresponding to different rotation-stop ratios are different, and even the shoes with larger sizes are not easily clamped in the ball brush type shoe washing machine under the combined action of the water flow, the impeller and the ball brush.

Therefore, when the shoe washing machine is used by adopting the control method, the shoes do not need to be distinguished according to different sizes before washing, and the shoe washing experience of users is obviously improved.

It will be understood by those skilled in the art that the control method of the shoe washing machine described above further includes other known structures such as a processor, a controller, a memory, etc., wherein the memory includes, but is not limited to, a random access memory, a flash memory, a read only memory, a programmable read only memory, a volatile memory, a non-volatile memory, a serial memory, a parallel memory or a register, etc., and the processor includes, but is not limited to, a CPLD/FPGA, a DSP, an ARM processor, a MIPS processor, etc. Such well-known structures are not shown in the drawings in order to not unnecessarily obscure embodiments of the present invention.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
