[0049] Background

[0050] Currently, fabric treatment machines on the market have relatively large washing capacities. While these machines are capable of washing large loads, due to their structural characteristics, laundry can become stuck in the door when washing large quantities, leading to blockages during the wash cycle. In severe cases, the blocked laundry cannot be released quickly, preventing effective washing and reducing the effectiveness of the wash cycle.

[0051] Based on this, Figure 1-Figure 2 As shown, a first aspect of an embodiment of the present application provides a method for detecting clothing blockage in a fabric processing device. The fabric processing device includes a fabric processing drum and a motor for driving the fabric processing drum to rotate. When the fabric processing device runs a washing program, the motor drives the fabric processing drum to rotate. The detection method includes:

[0052] Under the washing program, obtaining the average power value of the motor in each of n preset time periods;

[0053] Comparing the average power values ​​in two adjacent preset time periods, and determining whether, in n preset time periods, the average power values ​​of each of the two adjacent preset time periods are such that the average power value of the next preset time period is greater than the average power value of the previous preset time period, where n is a positive integer and n ≥ 10;

[0054] If so, it is determined that the clothes in the fabric treatment drum are clogged;

[0055] If not, it is determined that there is no blockage in the clothes in the fabric treatment drum.

[0056] The fabric processing device provided in the embodiment of the present application obtains the average power value of the motor in each of multiple preset time periods under a washing program; and determines whether the average power values ​​of each two adjacent preset time periods in the multiple preset time periods are both greater than the average power value of the previous preset time period. This can accurately feedback the blockage status of the clothes. Compared with the traditional clothing blockage detection method, this detection method has better accuracy and less misjudgment.

[0057] Preferably, the above-mentioned clothes blockage detection method is applied to a drum-type fabric processing device, taking the drum-type fabric processing device as a drum washing machine as an example.

[0058] Due to the characteristics of the rotation of the drum washing machine, the clogging of the clothes in the inner drum is a gradual process, and it will not be completely blocked all at once. Therefore, the corresponding relationship reflected in the power is the situation where the power changes gradually. It is worth noting that the reason why the average power value of the motor in multiple time segments is obtained in the embodiment of the present application, and the average power value of each two adjacent preset time periods is compared, and it is judged whether the average power value in the two adjacent preset time periods is that the average power value of the next preset time period is greater than the average power value of the previous preset time period, is to avoid using a one-time power judgment, which may cause misjudgment. Specifically, when the power of the motor suddenly increases, it is not necessarily caused by the blockage of clothes. It may also be caused by the influence of external power fluctuations, or other factors, or it may be caused by the blockage of clothes.

[0059] It should be noted that the reason why the embodiment of the present application determines whether the clothes are blocked by obtaining the power of the motor is because when the clothes are blocked, the most direct feedback is the change in the motor power, and obtaining the other parameters may not necessarily accurately reflect the blockage of the clothes.

[0060] Furthermore, in some possible implementations, obtaining an average power value of the motor in each of n preset time periods includes:

[0061] Continuously obtain an average power value of each preset time period in n preset time periods.

[0062] That is, during the rotation time of the motor, the rotation time of the motor is divided into multiple time periods, and the average power value of the motor in each time period is collected in sequence and continuously, so that the change of the motor power can be reflected more accurately.

[0063] Furthermore, in some possible implementations, the washing program includes a washing stage, wherein in the washing stage, the motor drives the fabric treatment drum to rotate periodically within a preset time period.

[0064] It should be noted that due to the periodic rotation of a drum washing machine during the wash cycle, that is, the washing machine's characteristic of alternating forward and reverse rotation during the wash cycle, a clothing blockage during clockwise operation will be undone when the washing machine rotates counterclockwise, and may no longer be blocked during subsequent clockwise and reverse cycles. Therefore, using traditional single-shot power determination and detection methods is more likely to result in misjudgments. However, the embodiments of the present application use multiple measured power values ​​for determination, fully considering the rotation characteristics of the washing drum during the wash cycle, thereby providing more accurate feedback on the clothing blockage situation within the drum and avoiding misjudgments.

[0065] It should also be noted that the above-mentioned washing program also includes a dehydration stage after the washing stage. When the fabric processing device runs the dehydration stage, the above-mentioned detection method can also be used to determine whether clothing clogging will occur during the dehydration stage.

[0066] Furthermore, in some possible implementations, each preset time period of the motor corresponds to a rotation cycle;

[0067] One rotation cycle of the motor is designed as: clockwise rotation-stop-counterclockwise rotation-stop.

[0068] Furthermore, in some possible embodiments, the detection method further comprises:

[0069] Obtaining the weight of the clothes in the fabric processing drum, and determining the value of n in n preset time periods according to the weight of the clothes;

[0070] The weight of the clothes in the fabric treatment drum is negatively correlated with the value of n.

[0071] That is, it can be understood that the fewer clothes there are in the fabric treatment drum, the smaller the probability of blockage, so it is necessary to make a judgment within a longer cycle; the more clothes there are, the greater the probability of blockage, and it is necessary to make a judgment within a shorter cycle to avoid the clothes from entering a blocked state and affecting the washing effect.

[0072] It should be noted that the weight of the laundry mentioned above can be the weight of dry laundry or wet laundry, but preferably, the weight of dry laundry is obtained, that is, the weight of the dry laundry placed in the fabric treatment tub is obtained before the washing process begins.

[0073] Specifically, in some possible implementations, the fabric processing device is preset with clothing weight levels, and different clothing weight levels correspond to different values ​​of n.

[0074] Specifically, the fabric processing device is preset with a clothing weight gear-n value correspondence table;

[0075] Determining the value of n in n preset time periods according to the weight of the laundry includes:

[0076] The clothing weight level is determined according to the weight of the clothing, and the n value is retrieved according to the determined clothing weight level.

[0077] The clothes are divided into the first gear, the second gear, the third gear and the fourth gear from light to heavy.

[0078] Determining a weight level of the clothes according to the weight of the clothes, and retrieving an n value according to the determined weight level of the clothes, including:

[0079] If the weight of the clothes is in the first gear, the determined n value is between 25 and 30;

[0080] If the weight of the clothes is in the second gear, the determined n value is between 20 and 25;

[0081] If the weight of the clothes is in the third gear, the determined n value is between 15 and 20;

[0082] If the laundry weight is at the fourth level, the determined n value is between 10 and 15.

[0083] Furthermore, in some possible implementations, after determining that the clothes in the fabric treatment drum are clogged, the method further includes:

[0084] Control the motor to stop, and control the motor to rotate again in a determined rotation direction after the motor stops;

[0085] The direction of rotation of the motor when it is restarted is opposite to the direction of rotation of the motor when the clothes are blocked.

[0086] Specifically, in some possible implementations, the motor has a maximum washing speed under the washing program;

[0087] Control the motor to stop, and then control the motor to rotate in the opposite direction after the motor stops, including:

[0088] Control the motor to rotate in the reverse direction at m times the maximum washing speed for t time;

[0089] Wherein m is a natural number greater than 1, and the value of m is positively correlated with the weight of the clothes in the fabric treatment drum, and the value of t is positively correlated with the weight of the clothes in the fabric treatment drum.

[0090] That is, it can be understood that the more clothes there are, the higher the rotation speed is required to remove the clothes from the blocked state, and it also takes a longer time to resolve the blockage.

[0091] Specifically, in some possible implementations, the laundry weight is divided into a first gear, a second gear, a third gear, and a fourth gear from light to heavy;

[0092] Control the motor to rotate in the reverse direction at m times the maximum washing speed for a time period of t, including:

[0093] If the weight of the clothes is in the first gear, the motor is controlled to rotate at 1.5 times the maximum washing speed for 10s-15s;

[0094] If the laundry weight is at the second gear, the motor is controlled to rotate at 2 times the maximum washing speed for 20s-25s;

[0095] If the laundry weight is at the third gear, the motor is controlled to rotate at 2.5 times the maximum washing speed for 25s-30s;

[0096] If the laundry weight is at the fourth gear, the motor is controlled to rotate at 3 times the maximum washing speed for 35s-40s.

[0097] In order to more clearly understand the control logic of the fabric processing device in the embodiment of the present application, the following Figure 2 To explain in detail:

[0098] First, before the washing machine enters the water, the weight of the laundry is measured. Based on the weight, the laundry is assigned to four different load levels: L1, L2, L3, and L4. During the washing process, control parameters are adjusted based on the load level. Clothes clogging increases the motor's power consumption; the more severe the clogging, the more pronounced the power change. By assessing the power value, an impending stall can be predicted.

[0099] The washing process of a drum washing machine is: clockwise rotation - stop - counterclockwise rotation - stop. During the first rotation cycle of the washing process (i.e., when the drum washing machine is rotating and washing), the motor power value of this rotation cycle is collected and the average value W1 is taken. During the second rotation cycle, the motor power value of this rotation cycle is similarly collected and the average value W2 is taken. During the third rotation cycle, the motor power value W3 is similarly collected. And so on, the motor power value Wn is collected for each rotation cycle.

[0100] The judgment condition is: within n+1 cycles, when W1<W2<W3<W4<....<Wn, it is determined that clothing clogging is about to occur in the n+1th cycle {It is worth noting that, preferably, the motor speed is the same within the n cycles in which the average motor power is required}. When the clothing weight is level L1, 25<n≤30; when the clothing weight is level L2, 20<n≤25; when the clothing weight is level L3, 15<n≤20; and when the clothing weight is level L4, 10<n≤15. It can be understood that the less clothing there is, the lower the probability of clogging, so the judgment needs to be made within a longer cycle; the more clothing there is, the greater the probability of clogging, so the judgment needs to be made within a shorter cycle to prevent the clothing from becoming clogged and affecting the washing effect.

[0101] When a stall is detected, the motor is immediately stopped. After stopping, the motor is then controlled to rotate at m times the wash speed, in the opposite direction of the previous rotation, for a duration of t. t is related to L1, L2, L3, and L4. The more laundry, the longer the stall will take. The corresponding values ​​for t are 10s-15s, 20s-25s, 25s-30s, and 35s-40s. m is related to L1, L2, L3, and L4. The more laundry, the higher the speed required to remove the laundry. m corresponds to 1.5 times, 2 times, 2.5 times, and 3 times, respectively. For example, if a stall is detected at a wash speed of 40 rpm and clockwise, the motor is controlled to rotate counterclockwise at 80 rpm for 20s-25s to clear the stall.

[0102] Furthermore, the second aspect of the embodiment of the present application further provides a drum-type fabric processing device, which includes the detection method provided in the first aspect of the embodiment. Preferably, the drum-type fabric processing device is a drum-type washing machine.
