As shown in fig. 1 to 6, the present invention discloses a method of detecting foreign matter in a laundry treating apparatus, comprising: presetting noise value d of clothes treatment device 0 Acquiring a noise value d of the laundry treatment apparatus during rotation of the tub, and comparing the acquired noise value d with a preset noise value d 0 If d > d 0 If so, the noise value is judged to be changed along with the rotation stop of the barrel body, and if so, the existence of foreign matters in the barrel body is judged.
Wherein, the last noise detection device that sets up of clothing processing apparatus, if: an audio detector; and in the rotating process of the barrel body, the noise detection device is controlled to be started for obtaining the noise value d of the clothes treatment device.
Specifically, as shown in fig. 1, the detecting step includes:
s1, starting to process clothes;
s2, presetting a noise value d of the clothes treatment device 0 ；
S3, acquiring a noise value d of the clothes treatment device;
s4, comparing whether the obtained noise value d is larger than a preset noise value d or not 0 (ii) a If yes, executing step S5; otherwise, executing step S5';

In the invention, if the acquired noise value d is larger than the preset noise value d 0 The noise generated in the rotating process of the barrel body is larger, and further the foreign matter possibly exists in the whole barrel body. At the moment, whether the noise value changes along with the rotation and stop of the barrel body is judged, if yes, the current noise is related to the rotation of the barrel body, the possibility of noise caused by external interference or hardware damage of the clothes processing device is eliminated, and the fact that foreign matters exist in the barrel body at present can be accurately judged.
As an embodiment of the present invention, the rotation and stop period of the tub is T 0 Presetting a detection period T 0 ' and T 0 ＇＞T 0 For example: a spin-stop period of T 0 For 2min, presetting a detection period T 0 ' is 2.5min.
Judging whether the noise value changes along with the rotation and stop of the barrel body comprises the following steps: judging in the preset detection period T 0 If the noise value d fluctuates, acquiring a fluctuation period T, presetting an offset value a, and calculating the fluctuation period T and the stop-and-go period as T 0 If the deviation value delta T is less than a, the noise value is judged to change along with the rotation and the stop of the barrel body.
Specifically, as shown in fig. 2, the detecting step includes:
s1, starting to process clothes;
s2, presetting a noise value d of the clothes treatment device 0 A rotation-stop period of T 0 Detection period T 0 "offset value a; for example: a spin-stop period of T 0 Is 2min, and the detection period T is preset 0 "is 2.5min, and deviation a is 0.2min;

S11, judging whether the clothes are processed or not; if so, ending the control; otherwise, return to step S3.
In this embodiment, if the noise value d is in advanceSetting a detection period T 0 To preset the detection period T by' internal fluctuation 0 ' greater than stall cycle is T 0 Then it indicates that the noise value is T at least in the rotation-stop period of one barrel body 0 Fluctuations occur therein, i.e. fluctuations in the noise level may be associated with a spin-stop of the tub.
At this time, the fluctuation period T and the spin-stop period are further calculated as T 0 If the deviation value delta T is smaller than the preset deviation value a, the fluctuation condition of the current noise value is closely related to the rotation and stop period of the barrel body, and further the fact that foreign matters exist in the barrel body at present and the clothes generate noise with fixed rhythm and fixed frequency in the rotation and stop time sequence of the barrel body is further shown.
As an implementation manner of the embodiment, the noise value d of the clothes treatment device is preset 0 The method comprises the following steps: presetting noise values corresponding to different types of clothes, acquiring the types of the clothes in the barrel body, and taking the noise value corresponding to the acquired types of the clothes as a preset noise value d 0 。
For example: the types of laundry include: clothes with metal buttons, clothes with plastic buttons and clothes without buttons. The preset noise value corresponding to the clothes with the metal buttons is d 01 The preset noise value corresponding to the clothes with the plastic buttons is d 02 The preset noise value corresponding to the clothes without buttons is d 03 ，d 01 ＞d 02 ＞d 03 。
In the present embodiment, different types of clothes correspond to different noise values d 0 Therefore, whether foreign matters really exist in the barrel body can be judged reasonably and accurately according to the actual types of the clothes.
For example, during the rotation of the tub, the clothes with the metal buttons will rub or collide with the tub to generate loud noise, and the preset noise value corresponding to the loud noise is controlled to be d 01 The size is large, and misjudgment caused by noise caused by the metal button in the process of detecting the foreign matters is avoided.
Similarly, during the rotation of the barrel body, the clothes without the buttons can not generate extra noise, and the corresponding preset noise value is controlledd 03 Less, so that the slight noise can be detected in time once the barrel body rotates, and the detection precision is higher.
As another embodiment of the present embodiment, a noise value d of the laundry treating apparatus is preset 0 The method comprises the following steps: presetting noise values corresponding to clothes of different weights, acquiring the weight of the clothes in the barrel, and taking the noise value corresponding to the acquired weight of the clothes as a preset noise value d 0 。
In the present embodiment, the larger the weight of the laundry, the larger the corresponding noise value. For example: the clothes with different weights comprise: 0-1Kg weight of clothes, 1-2Kg weight of clothes, 2-3Kg weight of clothes. A preset noise value d corresponding to 0-1Kg weight of laundry 04 The preset noise value corresponding to the clothes with the weight of 1-2Kg is d 05 A preset noise value d corresponding to 2-3Kg weight of clothes 06 ，d 06 ＞d 05 ＞d 04 。
In the present embodiment, clothes of different weights are associated with different noise values d 0 Therefore, whether foreign matters really exist in the barrel body can be judged reasonably and accurately according to the actual weight of the clothes.
For example, during the rotation of the tub, the noise generated by the friction and collision between the heavy laundry and the tub is relatively large, so the preset noise corresponding to the heavy laundry is controlled to be d 06 The size is large, and misjudgment caused by noise caused by large weight of clothes in the process of detecting foreign matters is avoided.
Similarly, in the rotating process of the barrel body, the noise value generated by friction and collision between the clothes with smaller weight value and the barrel body is smaller, so that the preset noise value corresponding to the noise value is controlled to be d 04 Less, so that the detection precision is higher as slight noise appears in the rotating process of the barrel body and the barrel body can be detected in time.
As another embodiment of this embodiment, a noise value d of the laundry treating apparatus is preset 0 The method comprises the following steps: presetting noise values corresponding to different rotation parameters of the barrel body, acquiring the current rotation parameters of the barrel body, and taking the noise values corresponding to the acquired rotation parameters as preset noise values d 0 。
In this embodiment, the rotation parameters of the barrel include a rotation/stop ratio, a rotation time, a stop time, a rotation speed, a rotation frequency, and the like of the barrel. The rotating parameters of the barrel body are different, and the corresponding stirring strength for the clothes in the barrel body is also different. In the present embodiment, the stronger the stirring intensity of the laundry, the higher the preset noise value d corresponding to the rotation parameter 0 The larger.
In this embodiment, the stronger the stirring strength of the drum for the laundry, the stronger the friction collision between the laundry and the drum is easily caused, so that the preset noise value corresponding to the friction collision is controlled to be d 0 And the device is large, so that misjudgment caused by noise caused by high stirring strength in the process of detecting foreign matters is avoided.
Similarly, the weaker the stirring strength of the barrel body to the clothes is, the weaker the friction collision between the clothes and the barrel body is, so that the preset noise value corresponding to the preset noise value is controlled to be d 0 Less, so that the slight noise can be detected in time once the barrel body rotates, and the detection precision is higher.
The present invention also provides a control method of a laundry treating apparatus including a tub for accommodating laundry, the control method including: and in the rotating process of the barrel body, judging whether foreign matters exist in the barrel body, and if so, controlling to increase the rotating speed of the barrel body.
In the invention, whether foreign matters exist in the barrel body can be judged by adopting any detection method of the embodiment of the invention; or, the invention can also adopt the detection method in the prior art to judge whether the foreign matter exists in the barrel body.
Specifically, as shown in fig. 3, the controlling step includes:
s1, starting to process clothes;
s2, judging whether foreign matters exist in the barrel body; if yes, executing step S3; otherwise, executing step S4;
s3, controlling and increasing the rotating speed of the barrel body;
s4, judging whether the clothes are processed or not; if so, ending the control; otherwise, return to step S2.
According to the invention, if the foreign matters exist in the barrel body, the rotating speed of the barrel body is controlled to be increased, the centrifugal force applied to the foreign matters is increased, the foreign matters are tightly attached to the inner wall of the barrel body under the action of larger centrifugal force and rotate along with the barrel body, collision and friction with the inner wall of the barrel body are avoided, noise can be effectively eliminated, a user does not need to pause to treat the foreign matters, and the efficiency of the clothes treatment device for treating clothes is improved.
As an implementation of this embodiment, controlling the rotation speed of the barrel to be increased includes: the rotating speed of the barrel body is controlled to be at least increased to a rotating speed d which enables the clothes to be in a state of being attached to the inner wall of the barrel body. The more the clothes in the barrel body, the greater the corresponding rotating speed d for enabling the clothes to be in a state of being attached to the inner wall of the barrel body.
In the embodiment, the rotating speed of the barrel body is at least increased to the rotating speed d which enables clothes to be in a state of being attached to the inner wall of the barrel body, so that the clothes can be tightly attached to the inner wall of the barrel body for washing or drying for a long time, and the clothes and foreign matters are prevented from freely falling down to impact the barrel body to generate noise under the low-speed rotating state of the barrel body.
As an embodiment of the present invention, a control method of a laundry treatment apparatus includes: if foreign matters exist in the barrel body, the rotating time of the barrel body is controlled to be increased, or the stopping time of the barrel body is controlled to be increased, or the rotating time and the stopping time of the barrel body are controlled to be increased in the rotating and stopping process of the barrel body; for example, the rotation stop ratio of the barrel may be increased from 10s.
Specifically, as an implementation manner in the present embodiment, as shown in fig. 4, the control step of the laundry treating apparatus includes:
s1, starting to process clothes;
s2, judging whether foreign matters exist in the barrel body; if yes, executing step S3; otherwise, executing step S4;
s3, controlling the rotating speed of the barrel body to be v and the rotating time to be t Rotating shaft A stop time period t Stop ；
S4, judging whether the clothes are processed or not; if so, ending the control; otherwise, return to step S2.
In this embodiment, if there is the foreign matter in the staving, then the rotational speed of control increase staving to guarantee that clothing and foreign matter keep adherence state, reduce the noise that clothing, foreign matter free fall and staving striking produced.
Further, if foreign matters exist in the barrel body, the rotating time of the barrel body is controlled to be increased, so that clothes and the foreign matters can keep a rotating state synchronous with the barrel body for a long time, and the noise is reduced. Similarly, if there is the foreign matter in the staving, long when the control increases the stopping of staving for clothing, foreign matter can keep the stall state long a period of time longer, can reduce the striking of clothing, foreign matter and staving inner wall like this, and then reduce the production of noise.
