Based on the clothes treatment equipment, the thread scraps treatment method provided by the embodiment of the invention comprises the following steps:

an inner cylinder and outer cylinder cleaning step, wherein theinner cylinder 200 rotates to generate surging water flow to clean thread scraps on theouter cylinder 100 and theinner cylinder 200; in this step, theinner cylinder 200 is rotated in a forward and reverse direction alternately, and the generated sloshing water flows to wash out the thread scraps attached to the inner wall of theouter cylinder 100 and the outer wall of theinner cylinder 200. Preferably, theinner tub 200 is rotated alternately in the forward and reverse directions at a rotation speed higher than that of a conventional washing process or rinsing process, thereby providing greater water flow energy, so that the inner and outer tubs can be washed by the sloshing water flow in a large area, and the cleaning effect of the inner and outer tubs is improved;

a filter screen cleaning step, wherein the filterscreen cleaning unit 500 sprays and cleans the thread scraps on thefilter screen unit 400; generally during this step, thescreen washing unit 500 intermittently provides a flow of spray water against thescreen unit 400, illustratively: a water inlet valve is arranged on a water supply pipeline of the filterscreen cleaning unit 500, the water inlet valve is intermittently opened according to program setting in the filter screen cleaning step, and the intermittent spray cleaning of thefilter screen unit 400 is realized, so that the cleaning effect of thefilter screen unit 400 can be improved, and water can be saved; the thread scraps cleaned in the step of cleaning the filter screen fall into theouter tub 100 along with the water flow;

a primary chip removal step, wherein the filings are discharged out of theouter barrel 100 in a drainage mode after the inner and outer barrel cleaning step or the filter screen cleaning step; since only the inner and outer tubs or thescreen unit 400 are previously cleaned, the lint cleaned into theouter tub 100 can be completely discharged with the washing water without clogging in one chip removal step with the drainage capability of the current laundry treating apparatus;

and a secondary chip removal step, wherein at least one inner and outer cylinder cleaning step and/or one filter screen cleaning step are separated from the primary chip removal step. After the inner and outer cylinder cleaning step or the filter screen cleaning step is performed once, the amount of the thread scraps cleaned in theouter cylinder 100 in the same cleaning step which is performed again is obviously reduced, so that the secondary thread scrap removal step has a large time sequence adjustment space in the whole thread scrap cleaning process based on the setting of the primary thread scrap removal step, and the limitation of the thread scrap treatment method in practical application of the embodiment of the invention can be reduced by the setting, for example, the time sequence of the secondary thread scrap removal step in the thread scrap treatment method is adjusted according to the clothes washing program of the clothes treatment equipment, so that the thread scrap treatment method is better embedded into the clothes washing program.

Therefore, the thread scrap processing method according to the embodiment of the invention can set the following schemes according to actual needs:

1. inner and outer cylinder cleaning → primary chip removal → filter screen cleaning → secondary chip removal;

with reference to fig. 3, in the present scheme, the inner and outer tube cleaning step, the primary chip removal step, the filter screen cleaning step, and the secondary chip removal step are sequentially performed, the chips cleaned in the inner and outer tube cleaning step and the filter screen cleaning step are discharged from theouter tube 100 by the respective chip removal step performed later, and the whole chip treatment method has a short flow, so as to achieve the requirement of quick and effective cleaning.

The sequence of the filter screen cleaning step and the inner and outer cylinder cleaning steps can be changed, and the implementation effect is the same as that of the filter screen cleaning step and the inner and outer cylinder cleaning steps.

2. Inner and outer cylinder cleaning → primary chip removal → inner and outer cylinder cleaning → filter screen cleaning → secondary chip removal;

with reference to fig. 4, in the present embodiment, a chip removal step is inserted between two inner and outer cylinder cleaning steps, a filter screen cleaning step is performed after the second inner and outer cylinder cleaning step, and finally, a secondary chip removal step is performed, after the first inner and outer cylinder cleaning step and the primary chip removal step, most of the chips and impurities on the inner and outer cylinders are removed and are discharged out of theouter cylinder 100, the amount of chips in theouter cylinder 100 cleaned in the second inner and outer cylinder cleaning step is significantly reduced, and even if the second inner and outer cylinder cleaning step and the filter screen cleaning step are provided before the secondary chip removal step, the secondary chip removal step has the capability of completely discharging the chips out of theouter cylinder 100. In addition, in the scheme, the inner barrel cleaning step and the outer barrel cleaning step are performed twice at intervals, so that theinner barrel 200 and theouter barrel 100 can obtain better cleaning effect.

In the scheme, the inner and outer cylinder cleaning steps can be increased to three times or more times according to actual needs; two or more filter screen cleaning steps can be carried out before the secondary chip removal step.

3. Inner and outer cylinder cleaning → primary chip removal → inner and outer cylinder cleaning → secondary chip removal → filter screen cleaning → tertiary chip removal;

with reference to fig. 5, in the present solution, the inner and outer cylinder cleaning steps are performed at intervals, and the chip removal step is performed next to the inner and outer cylinder cleaning step each time, which is equivalent to circulating the inner and outer cylinder cleaning step and the chip removal step twice, and then performing the filter screen cleaning step and the chip removal step three times. The invention provides a concept of chip removal in a grading way, aims to reduce the quantity of thread scraps in a single chip removal step, is not limited to a secondary chip removal step in practical application, and can be increased to three times or more times according to the requirements of practical situations.

Several specific implementations of the chip-removal method according to the present invention are given above, but the implementation of the present invention is not limited thereto, and other implementations derived from the above implementations still fall within the protection scope of the present invention as long as they do not substantially depart from the chip-removal concept according to the present invention.

In the embodiment of the invention, the thread scraps processing method is embedded into the washing process of the clothes processing equipment, for example, at the later stage of the clothes washing process, the inner and outer cylinder cleaning and the filter screen unit cleaning are completed by the thread scraps processing method of the embodiment of the invention, and the inner and outer cylinder cleaning and the filter screen unit cleaning can use clothes washing water, thereby saving water.

In other embodiments of the present invention, the laundry treating apparatus is provided with an independent lint treating process, the lint treating process can be performed before the laundry is washed or after the laundry is washed, the lint treating process and the washing process are not interfered with each other, and the lint treating process and the washing process can be performed by a user according to actual needs. Because the inner drum has no clothes in the thread scrap processing process, even if water in the outer drum enters the inner drum, secondary pollution to the clothes can not be caused.

In one embodiment of the invention, based on the scheme of the previous embodiment, the inner and outer cylinder cleaning step is performed between the filter screen cleaning step and the secondary chip removal step. The lint cleaned in the screen cleaning step falls into theouter tub 100, and some of the lint may adhere to the upper portion of the outer wall of theinner tub 200 and cannot be discharged with the water flow.

In one embodiment of the invention, based on the scheme of the previous embodiment, the chip removal step is optimized: the primary chip removal step is set to intermittent drainage. According to the foregoing embodiment of the present invention, the primary chip removal step and the secondary chip removal step both discharge the chips out of theouter tub 100 by draining, the draining is usually performed by a draining pump/draining valve, and the draining pump/draining valve is intermittently opened according to the program setting when the primary chip removal step is performed, so as to discharge the water in theouter tub 100 for multiple times, thereby achieving better chip removal effect. In practical application, intermittent drainage can be adopted in both the primary chip removal step and the secondary chip removal step; intermittent drainage can be adopted in one of the primary chip removal step and the secondary chip removal step.

In one embodiment of the present invention, based on the solution described in the previous embodiment, the laundry treating apparatus is a drum washing machine, when the thread-scraps treating method is engaged in the washing stroke of the laundry treating apparatus, in order to obtain a better washing effect, theinner tub 200 is set at a higher rotation speed to generate a stronger turbulent water flow, and if the original water level of theouter tub 100 is higher, water with thread scraps entrained in the inner and outer tub washing steps is liable to enter theinner tub 200 from the laundry inlet of theinner tub 200, resulting in secondary contamination of the laundry. To solve the above problem, the relationship between the inner cylinder rotation speed w and the outer cylinder water level h of theinner cylinder 200 in a static state needs to be considered, if the outer cylinder water level h is high, theinner cylinder 200 needs to operate at a low inner cylinder rotation speed w, and if the outer cylinder water level h is low, the inner cylinder rotation speed w can be increased appropriately to improve the cleaning effect.

Referring to fig. 6 and 7, the radial distance between theouter cylinder 100 and theinner cylinder 200 is H1, the radial distance between the lower edge of the laundry inlet of theinner cylinder 200 and the lower edge of theouter cylinder 100 is H2, the water level of the outer cylinder in the static state of the inner cylinder is H, the water level increment of the outer cylinder when theinner cylinder 200 rotates is H0, and H is not less than H1 and not more than H2-H0. Wherein H1 is less than or equal to H, so that enough cleaning water can be flushed to theinner cylinder 200 and theouter cylinder 100 in the inner and outer cylinder cleaning steps; when theinner drum 200 rotates, part of water in theinner drum 200 is thrown to two axial sides of theouter drum 100 by centrifugal action, so that water levels on two axial sides of theouter drum 100 rise, and the larger the inner drum rotating speed w is, the larger the rising amplitude of the water levels is, as shown in fig. 7, at this time, the water level of theouter drum 100 on one side of the clothes throwing-in opening is H + H0, if the inner drum rotating speed w is too large, H + H0 is larger than H2, water in theouter drum 100 enters theinner drum 200 from the clothes throwing-in opening, and therefore H is less than or equal to H2-H0.

However, in practical situations, the diameters and depths of the inner cylinders and the diameters and depths of the outer cylinders of different types of products are different, and if the uniform curing standard is adopted to control the rotating speed w of the inner cylinder, the control of the water level of the outer cylinder in the cleaning step of the inner cylinder and the outer cylinder of each type of product can not be met obviously, and therefore, the invention provides the following scheme:

the clothes treating apparatus has a control part and a water level sensor for detecting the water level of the outer tub, the control part performs water level grade judgment according to the detection data of the water level sensor and controls the inner tub rotating speed w according to the water level grade judgment result. Specifically, in the control unit of this embodiment, a water level-inner cylinder rotation speed relation database is pre-established, as shown in table 1 below:

as can be seen from table 1, each water level has an associated inner drum speed w, and the relationship between these is obtained by simulation, which is exemplary: setting N water level grades, selecting one water level grade to inject water matched with the water level into theouter cylinder 100, operating theinner cylinder 200 in a mode of increasing the rotating speed until the water level of the outer cylinder reaches the lower edge of a clothes inlet of theinner cylinder 200, recording the rotating speed of the inner cylinder at the moment, namely obtaining the highest rotating speed of the inner cylinder corresponding to the water level grade, in other words, keeping the water level of the outer cylinder under the water level grade, and avoiding the water in theouter cylinder 100 from entering theinner cylinder 200 as long as the actual rotating speed of the inner cylinder does not exceed the highest rotating speed of the inner cylinder. And the other water level grades obtain corresponding inner cylinder rotating speed w according to the experimental method, and a plurality of products with different models establish the water level grade-inner cylinder rotating speed relation database according to the size difference of the inner cylinder and the outer cylinder so as to control the inner cylinder rotating speed based on the outer cylinder water level detection in the inner and outer cylinder cleaning step.

It is worth mentioning that: it was also found in the above experiment that when the water level of the tub is at or below a certain water level, the water in thetub 100 does not enter thetub 200 even if the tub rotation speed reaches a limit rotation speed (the highest rotation speed that the laundry treating apparatus allows thetub 200 to reach), in which case, this water level is defined as a critical water level, and all the water level levels given in the above table 1 and the tub rotation speed w corresponding thereto are obtained in the case where the water level h of the tub is greater than the critical water level. Therefore, when the inner and outer tub cleaning step is performed, if the water level determination result is the critical water level or below the critical water level, theinner tub 200 is allowed to operate at any rotational speed not exceeding the limit rotational speed; and if the water level is higher than the critical water level, matching the inner cylinder rotating speed w according to the water level grade corresponding to the actual outer cylinder water level.

The clothes treatment equipment provided by the embodiment of the invention is a drum washing machine or a pulsator washing machine.

While the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that the present invention may be practiced without limitation to such specific embodiments. Any modifications which do not depart from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
