[0057] When washing shoes in an existing shoe washing machine, some shoes made of materials have strong buoyancy and can float on the surface of the washing water. Such shoes do not contact the brush on the impeller, resulting in poor washing effect; some shoes made of materials sink to the bottom of the washing drum. Such shoes are always in contact with the brush on the impeller, which will cause wear on the surface of the shoes when the washing force is strong; that is, the appropriate washing method is not selected according to the state of the shoes in the washing drum, resulting in poor washing effect or large wear on the surface of the shoes during washing;

[0058] The present invention creatively provides a method for determining the state of shoes in a washing drum. When the washing water in the washing drum is at different liquid levels, the total number of pulses of a driving motor at the corresponding moment is obtained; the change value of the total number of pulses when the washing water is at different liquid levels is calculated; according to the change value of the total number of pulses, the state of the shoes in the washing drum can be accurately determined, and then the washing process of the shoes can be controlled, thereby reducing the surface wear of the shoes and improving the washing effect.

[0059] Example 1

[0060] like Figure 1As shown, this embodiment provides a method for determining the state of shoes in a washing drum, which is used in a shoe washing machine; the shoe washing machine comprises a washing drum, a pulsator and a driving motor, the washing drum comprises a side wall and a bottom wall, a brush is arranged on the inner wall surface of the side wall of the washing drum, the pulsator is rotatably arranged in the washing drum and arranged on the bottom wall, the driving motor is drivingly connected to the pulsator, and a brush is arranged on the top of the pulsator; when the shoe washing machine washes shoes, the shoes are placed in the washing drum, the driving motor drives the pulsator to rotate, stirs the water flow, and the brushes on the side wall and the brushes on the pulsator rotate relative to the shoes, thereby washing the shoes; according to different positions of the shoes in the washing drum, the shoes have multiple different states;

[0061] Methods for determination include:

[0062] S1, delivering washing water into the washing tub and controlling the driving motor to rotate according to a preset mode;

[0063] S2, when the washing water in the washing tub is at different liquid levels, obtaining the total number of pulses of the driving motor at the corresponding moment;

[0064] S3, calculating the change value of the total number of pulses when the washing water is at different liquid levels;

[0065] S4, determining the state of the shoes in the washing drum according to the change value of the total number of pulses;

[0066] Among them, the preset mode is that the drive motor runs in the order of forward rotation, stop, reverse rotation and stop. For example, the preset mode is that the drive motor first rotates forward for t1 second, then stops for t2 seconds, then reverses for t3 seconds, and then stops for t4 seconds; the drive motor first drives the impeller to rotate and then stops. Due to inertia, the impeller will stop running after a period of time; after the drive motor stops, the total number of pulses of the drive motor can be collected during the time from the impeller rotating to stopping.

[0067] Taking the case where the liquid levels of the washing water in the washing tub are h1 and h2 respectively as an example, further explanation is given; when the liquid level of the washing water in the washing tub is h1, the total number of pulses obtained is p1; when the liquid level of the washing water in the washing tub is h2, the total number of pulses obtained is p2; wherein, h2>h1;

[0068] S4 includes:

[0069] S41, calculating the difference between p1 and p2: Δp=p2-p1 or Δp=p1-p2;

[0070] S42, determining whether Δp is within a preset range;

[0071] S43, determining the state of the shoes in the washing tub according to the judgment result of whether Δp is within the preset range.

[0072] Specifically, the state of the shoe includes at least a first state, a second state and a third state; S43 includes:

[0073] S431, when Δp=p2-p1 and Δp is greater than the maximum threshold of the preset interval, determining that the state of the shoe is the first state;

[0074] S432, when Δp=p2-p1 and Δp is in a preset interval, determining that the state of the shoe is the second state;

[0075] S433, when Δp=p2-p1 and Δp is less than the minimum threshold of the preset interval or when Δp=p1-p2 and Δp is less than the minimum threshold of the preset interval, determine that the state of the shoe is the third state;

[0076] Among them, when the shoe is in the first state, at least a part of the shoe floats on the liquid surface of the washing water in the washing drum and the shoe does not contact the impeller; when the shoe is in the second state, the entire shoe floats in the washing water in the washing drum; when the shoe is in the third state, the entire shoe sinks to the bottom of the washing drum and contacts the impeller.

[0077] Specifically, when the liquid level of the washing water changes, the buoyancy of the shoes given by the washing water changes, and the state of the shoes in the washing water changes; if the shoes float, the contact area between the shoes and the brush on the pulsator is greatly reduced or the shoes and the brush on the pulsator are not in contact, then the resistance to the rotation of the pulsator becomes smaller, and the total number of pulses of the driving motor becomes larger; therefore, when Δp=p2-p1 and Δp is greater than the maximum threshold value of the preset interval, it is determined that the state of the shoes is the first state;

[0078] If the shoes float in the middle of the washing water, the contact area between the shoes and the brush on the impeller becomes smaller, the resistance of the impeller rotation becomes smaller, and the total number of pulses of the driving motor becomes larger; therefore, when Δp=p2-p1 and Δp is in the preset interval, it is determined that the state of the shoes is the second state;

[0079] If the shoes sink to the bottom of the washing drum, the contact area between the shoes and the brush on the impeller is basically unchanged, the resistance to the rotation of the impeller is basically unchanged, and the total number of pulses of the driving motor is basically unchanged; therefore, when Δp=p2-p1 and Δp is less than the minimum threshold of the preset interval or when Δp=p1-p2 and Δp is less than the minimum threshold of the preset interval, it is determined that the state of the shoes is the third state;

[0080] That is, when the state of the shoes in the washing water is different, the load of the driving motor is different, and thus the total number of pulses of the driving motor is different; based on the change in the total number of pulses of the driving motor, the state of the shoes in the washing water can be determined.

[0088] For example, when the driving motor is in the second washing mode, the driving motor runs alternately in forward and reverse directions, and stops between forward and reverse directions; that is, in one cycle of alternating forward and reverse directions, the driving motor first rotates forward for t1 second, then stops for t2 seconds, then reverses for t3 seconds, and then stops for t4 seconds.

[0093] P16, re-determining the state of the shoes in the washing drum according to the change value of the recalculated total number of pulses;

[0094] P17. According to the re-determined state of the shoes, control the shoe washing machine to run the washing program.

[0095] Specifically, P16 includes:

[0096] P161, calculate the difference between p1 and p3 Δp'=p3-p1 or Δp'=p1-p3;

[0097] P162, determine whether Δp' is within the preset range;

[0102] When Δp'=p3-p1 and Δp' is within the preset interval, the state of the shoe is re-determined to be the second state;

[0103] When Δp′=p3-p1 and Δp′ is smaller than the minimum threshold of the preset interval or when Δp′=p1-p3 and Δp′ is smaller than the minimum threshold of the preset interval, the state of the shoe is re-determined to be the third state.

[0104] P17 includes:

[0105] When the state of the shoes is determined to be the first state again, the driving motor is controlled to rotate according to the first washing mode;

[0108] Wherein, when the driving motor is in the first washing mode, the second washing mode and the third washing mode, the driving motor runs alternately in forward and reverse directions, and the period of the alternating forward and reverse directions when the driving motor is in the first washing mode is greater than the period of the alternating forward and reverse directions when the driving motor is in the second washing mode, and the period of the alternating forward and reverse directions when the driving motor is in the second washing mode is greater than the period of the alternating forward and reverse directions when the driving motor is in the third washing mode;

[0109] When the shoe is in the first state, at least a portion of the shoe floats on the liquid surface of the washing water in the washing tub, so that the driving motor is in the first washing mode to increase the washing effect;

[0110] When the shoes are in the second state, the shoes are completely floated in the washing water in the washing tub, so that the driving motor is in the second washing mode, and the shoes are washed by the brushes on the side walls and the impeller and the washing water, so that the shoes can be washed comprehensively and thoroughly;

[0111] When the shoes are in the third state, the shoes are completely sunk to the bottom of the washing tub, so that the driving motor is in the third washing mode, which can prevent the brush from wearing the surface of the shoes.
