[0049] Background

[0050] The washing capacity of fabric processing equipment on the market is relatively large. Common fabric processing equipment can wash more clothes, but due to the structural characteristics of fabric processing equipment, when washing a large amount of clothes, clothes may get stuck in the door, resulting in blockage during the washing process. In serious cases, the blocked clothes cannot be loosened in time, resulting in the inability to effectively wash the clothes, reducing the washing effect of the clothes.

[0051] Based on this, Figure 1-Figure 2 As shown, the first aspect of the embodiment of the present application provides a method for detecting clothing blockage in a fabric processing device, wherein 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 an average power value of the motor in each of n preset time periods;

[0053] Compare the average power values ​​in two adjacent preset time periods, and determine whether the average power values ​​of each of the two adjacent preset time periods in n 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 clogging of 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 clogging situation of the clothes. Compared with the traditional clothing clogging 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 rotation characteristics of the drum washing machine, the clogging of the clothes in the inner drum is a gradual process, and there will not be a situation where it is completely blocked all at once. Therefore, the corresponding relationship reflected in the power is the situation where the power changes gradually. It is worth explaining 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 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 clothing is blocked by obtaining the power of the motor is because the most direct feedback when the clothing is blocked is the change in the motor power, and obtaining the other parameters may not necessarily accurately reflect the blockage of the clothing.

[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 more accurately reflected.

[0063] Further, 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 characteristics of the drum washing machine during the washing stage, that is, the characteristics of the washing machine rotating alternately forward and reverse during the washing stage, when the washing machine is running clockwise, the clothes will be blocked, and when the washing machine rotates counterclockwise, the blockage will be undone in the opposite direction, and it may not be blocked during the subsequent forward-reverse operation. Therefore, the traditional method of judging and detecting the power once is more likely to cause misjudgment. In the embodiment of the present application, multiple measured power values ​​are used for judgment, which fully considers the rotation characteristics of the washing drum of the washing machine during the washing stage, so that the blockage of the clothes in the drum can be fed back more accurately, avoiding the occurrence of misjudgment.

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

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

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

[0069] Obtaining the weight of the clothes in the fabric treatment 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 n value.

[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 period; the more clothes there are, the greater the probability of blockage, so it is necessary to make a judgment within a shorter period to avoid the clothes entering a blockage state and affecting the washing effect.

[0072] It should be noted that the weight of the clothes mentioned above may be the weight of dry clothes or the weight of wet clothes, but preferably, the weight of dry clothes is obtained, that is, the weight of dry clothes put into the fabric treatment drum is obtained before the washing process starts.

[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 the 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 weight of the clothes is divided into the first gear, the second gear, the third gear and the fourth gear from small to large;

[0078] Determining a weight level of the clothes according to the weight of the clothes, and retrieving the 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 10-15.

[0083] Further, 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 rotation direction of the motor when it is restarted is opposite to the rotation direction 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 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 a period of t;

[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 weight of the clothes is divided into a first gear, a second gear, a third gear and a fourth gear from small to large;

[0092] Control the motor to rotate in the reverse direction at m times the maximum washing speed for a period of time 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 weight of the clothes is in the second gear, the motor is controlled to rotate at twice the maximum washing speed for 20s-25s;

[0095] If the weight of the clothes is in 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, Figure 2 To explain in detail:

[0098] First, before the washing water enters the washing machine, the weight of the laundry is obtained by weighing. According to the weighing, the weight of the laundry corresponds to four gears from small to large, namely L1, L2, L3, and L4. During the washing process, different control parameters are adjusted according to different weight gears. When the laundry is blocked, the power of the motor will increase. The more serious the blockage, the more obvious the change in power. By judging the power value, it is possible to predict the impending stall.

[0099] The washing process of the drum washing machine is: clockwise rotation-stop-counterclockwise rotation-stop. In the first rotation cycle of the washing process, that is, when the drum washing machine rotates for washing, the power value of the motor in this rotation cycle is collected and the average value W1 is taken; in the second rotation cycle, the power value of the motor in this rotation cycle is also collected and the average value W2 is taken; in the third rotation cycle, the power value W3 of the motor in this rotation cycle is also collected. And so on, in each rotation cycle, the power value Wn of the motor in this cycle is collected.

[0100] The judgment condition is: within n+1 cycles, when W1<W2<W3<W4<....<Wn, it is judged that the clothing is about to be blocked in the n+1th cycle {it is worth noting that, preferably, the motor speed is the same within the n cycles where the average power of the motor needs to be obtained}. When the weight of the clothing is L1, 25<n≤30; when the weight of the clothing is L2, 20<n≤25; when the weight of the clothing is L3, 15<n≤20; when the weight of the clothing is L4, 10<n≤15. It can be understood that the less clothing there is, the smaller the probability of blockage, so it is necessary to make a judgment within a longer cycle; the more clothing there is, the greater the probability of blockage, and it is necessary to make a judgment within a shorter cycle to avoid the clothing from entering a blocked state and affecting the washing effect.

[0101] After the stall is detected, the motor is controlled to stop rotating immediately. After stopping rotating, the motor is controlled to rotate at a speed m times the washing speed in the opposite direction of the last rotation, and maintained for t time. Among them, t is related to L1, L2, L3, and L4. It can be understood that the more clothes there are, the longer it takes to solve the stall. t corresponds to 10s-15s, 20s-25s, 25s-30s, and 35s-40s. Among them, m is related to L1, L2, L3, and L4. It can be understood that the more clothes there are, the higher the speed required to solve the stall, so that the clothes can be pulled out of the stall state. m corresponds to 1.5 times, 2 times, 2.5 times, and 3 times respectively. For example, when the weight of the clothes is L2, if the washing speed is 40rpm and the stall is detected when rotating clockwise, the motor is controlled to rotate counterclockwise at 80rpm for 20s-25s to solve the stall problem.

[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.
