[0029] Embodiment 1

[0030] See also Figure 1 , Figure 1 This is a flow chart of the steps of a method for protecting a clothes drying machine from obstruction provided in Example 1 of the present application.

[0031] A method for protecting a clothes drying machine from obstruction comprises the following steps:

[0032] S101, obtaining a starting current value of the clothes drying machine;

[0033] S102, according to the preset current interval in which the starting current value is located, obtaining a resistance current threshold value corresponding to the preset current interval; wherein the preset current interval includes a plurality of current intervals, each of the current intervals corresponding to a different resistance current threshold value;

[0034] S103, obtaining a real-time current value of the clothes drying machine, and obtaining a current fluctuation value according to a difference between the real-time current value and the starting current value; wherein the real-time current value is an instantaneous current value of the clothes drying machine at a certain time point in an operation cycle;

[0035] S104: If the current fluctuation value exceeds the resistance current threshold, start resistance protection of the clothes drying machine.

[0036] The clothes dryer provided in the present application has an obstruction protection method, which is provided with multiple current intervals, and each current interval generates a corresponding obstruction current threshold. When the clothes dryer is started, the starting current value of the clothes dryer is obtained, and the corresponding obstruction current threshold is set according to the current interval in which the starting current value is located. The real-time current value of the clothes dryer is obtained during the rising process of the clothes dryer, so as to obtain the current fluctuation value, and the current fluctuation value is monitored. If the current fluctuation value exceeds the set obstruction current threshold, the obstruction protection of the clothes dryer is triggered, and the obstruction current threshold is selected according to different starting currents, so that the obstruction protection can be triggered more timely when the clothes dryer is hung with a light weight, and at the same time, the obstruction trigger threshold is increased under the condition of heavy hanging weight to avoid the problem of false triggering.

[0037] In step S101, a starting current value of the clothes drying machine is obtained.

[0038] The starting current value refers to the current value obtained from startup to stable operation during the actual operation of the clothes drying machine. The magnitude of the starting current value is determined by the hanging weight of the clothes drying machine. The greater the hanging weight of the clothes drying machine, the greater the starting current value, and the smaller the hanging weight of the clothes drying machine, the smaller the starting current value. In one embodiment, stable operation means that the clothes drying machine is in a rated working state.

[0039] See also Figure 2 , Figure 2 A flowchart of the steps of starting a clothes drying machine provided in the first embodiment of the present application. In one embodiment, before obtaining the starting current value of the clothes drying machine, the following steps are included:

[0040] S01, receiving a start instruction of a clothes drying machine, calling a clothes drying machine start program, and controlling the clothes drying machine to start;

[0041] S02, using a preset speed regulation method to gradually make the running speed of the clothes drying machine reach a preset maximum speed; wherein, when the running speed of the clothes drying machine is the preset maximum speed, the clothes drying machine is in a rated working state.

[0042] The preset speed regulation method is used to control the speed of the clothes drying machine so that the clothes drying machine can adjust its running speed. For example, after calling the clothes drying machine startup program, the clothes drying machine is controlled to gradually increase from a stationary state to a set maximum speed.

[0043] In one embodiment, the speed regulation method is a pulse width modulation (PWM) motor speed regulation technology, the principle of which is to convert an analog signal into a digital signal, and then control the output of the analog signal by adjusting the duty cycle of the digital signal. After the clothes dryer is started, by gradually increasing the duty cycle of the PWM signal, the rising voltage of the clothes dryer motor gradually increases from 0V to the maximum operating voltage of the motor, and the speed of the motor increases accordingly, so that the running speed of the clothes dryer gradually increases to the maximum speed preset by the user or the system. In this embodiment, when the clothes dryer reaches the preset maximum speed, it can be regarded as being in the rated working state.

[0044] See also Figure 3 , Figure 3 A flowchart of the steps of obtaining the starting current value of a clothes drying machine provided in the first embodiment of the present application. In one embodiment, the step of obtaining the starting current value of the clothes drying machine includes the following steps:

[0045] S01a, obtaining a sample current value of the clothes drying machine within a preset sampling time;

[0046] The preset sampling time is a timing period set by the user in the system for obtaining the current value. In one embodiment, the current value of the clothes drying machine is sampled by setting the preset sampling time to obtain the sample current value of the clothes drying machine. For example, the preset sampling time is set to 500ms, and the sampling time starts when the clothes drying machine reaches the rated working state, and the timing period is 500ms. Further, within the timing period, sampling is performed at a preset sampling interval to obtain a set of sample current value data, which includes multiple sample current values, and the sample current value reflects the operating current state of the clothes drying machine just after it reaches the rated working state.

[0047] S02a, performing mean calculation on the sample current values ​​to obtain an average value of the sample current values, and using the average value as a starting current value.

[0048] According to the sample current value obtained in step S01a, the average value of the sample current is calculated to obtain the average value of the sample current. The average current value of the clothes drying machine in a stable state is obtained through the current data within the preset sampling time, and the starting current value of the clothes drying machine is determined, so as to better reflect the starting state of the clothes drying machine during the current operation.

[0049] In this embodiment, after the timing cycle ends, the average value of the sample current value is collected and calculated, and the average value represents the stable operating current of the clothes drying machine motor after it starts and reaches the maximum speed and enters the rated working state, and the average value is used as the starting current value of this startup. Using the average current value within a period of stable operation as the starting current value can be used to evaluate the starting performance of the motor and make the starting current value closer to the actual operating condition of the clothes drying machine.

[0050] For step S102, according to the preset current interval in which the starting current value is located, the resistance current threshold corresponding to the preset current interval is obtained.

[0051] In one embodiment, according to the method of obtaining the starting current value of the clothes drying machine in the above steps S01a and S02a, the starting current value corresponding to the minimum hanging weight / empty hanging of the clothes drying machine and the starting current value corresponding to the maximum hanging weight are obtained, and the starting current value range of the clothes drying machine is obtained, wherein, in a normal state, the smaller the hanging weight, the smaller the starting current value; the larger the hanging weight, the larger the starting current value. The system or the user divides the starting current value range into several starting current ranges according to the preset starting current range division rules, and sets different encounter current thresholds for each starting current range.

[0052] See also Figure 4 , Figure 4A flowchart of the steps of obtaining a preset current interval is provided in the first embodiment of the present application. In one embodiment, obtaining the preset current interval includes the following steps:

[0053] S201, obtaining a hanging weight data set of a clothes drying machine and starting current data corresponding to each hanging weight data in the hanging weight data set;

[0054] S202, classifying the hanging weight data into intervals, and dividing them into a plurality of hanging weight intervals;

[0055] S203, generating a preset current interval according to the starting current data corresponding to the weight-hanging interval; wherein the weight-hanging interval corresponds to the current interval in the preset current interval one by one.

[0056] Different hanging weights are classified into intervals according to hanging weight data, and the hanging weight data is the hanging weight value under different hanging weight conditions. For example, in one embodiment, according to the size range of hanging weight data, it is divided into a small hanging weight interval, a medium hanging weight interval and a large hanging weight interval, and the range and number of the hanging weight intervals can be set by the user or the system, and are not further limited here. In this embodiment, according to the divided hanging weight intervals, a number of preset current intervals are generated, and the hanging weight intervals correspond to the current intervals one by one.

[0057] In one embodiment, the starting current value interval is divided into multiple current intervals, so that different current intervals correspond to different clothes drying machine hanging weight ranges. Each time the clothes drying machine is used, the obstruction current threshold is set according to the current interval in which the starting current is located at startup, and different obstruction current thresholds are provided for clothes drying machines under different hanging weights, so that the clothes drying machine can trigger obstruction protection more accurately.

[0058] According to the inventive concept of the present application, each current interval is correspondingly provided with a different resistance current threshold. Obtaining the resistance current threshold comprises the following steps:

[0059] According to a preset resistance current threshold calculation formula, a resistance current threshold corresponding to each current interval is generated. The resistance current threshold calculation formula is used to calculate the resistance current threshold corresponding to each current interval.

[0060] In one embodiment, the resistance current threshold corresponding to each current interval is calculated according to a preset resistance current calculation formula, and the resistance current calculation formula is pre-set according to the starting current of the clothes drying machine, the hanging weight of the clothes drying machine and a preset compensation value.

[0061] According to step S103, the real-time current value of the clothes drying machine is obtained, and the current fluctuation value is obtained according to the difference between the real-time current value and the starting current value.

[0062] The real-time current value is the instantaneous current value of the clothes drying machine at a certain time point in the operation cycle. During the operation cycle of the clothes drying machine, the current data is collected by the current sensor or current monitoring module in the current sampling circuit, and the current data corresponding to each time is the real-time current value of the clothes drying machine.

[0063] The current fluctuation value is the fluctuation value of the real-time current of the clothes drying machine during operation, and the magnitude of the current fluctuation value reflects the stability of the operation of the clothes drying machine. In one embodiment, based on the real-time current value and the starting current value obtained by the above step S101, the difference between the real-time current value and the starting current value is calculated, that is, the real-time current value corresponding to each time point is obtained, and the difference is made with the starting current value respectively, and the current fluctuation value corresponding to each time is calculated. The current fluctuation value is the difference between the real-time current value and the starting current value, wherein, under normal operating conditions, the smaller the weight of the clothes drying machine, the smaller the current fluctuation value; the larger the weight of the clothes drying machine, the larger the current fluctuation value. Correspondingly, the current interval where the smaller starting current value is located has a small corresponding resistance current threshold; the current interval where the larger starting current value is located has a large corresponding resistance current threshold.

[0064] In this embodiment, after starting the clothes dryer, the starting current value obtained after the clothes dryer runs stably is obtained, and the corresponding obstruction current threshold is obtained according to the current range in which the starting current value is located. The current value of the clothes dryer is detected in real time during the operation of the clothes dryer, and the real-time current fluctuation value of the clothes dryer is obtained. If the current fluctuation value exceeds the set obstruction current threshold, the obstruction protection of the clothes dryer is triggered to prevent the clothes dryer from being damaged by obstruction.

[0065] Regarding step S104, if the current fluctuation value exceeds the resistance current threshold, resistance protection of the clothes drying machine is started.

[0066] In one embodiment, if it is detected that the current fluctuation value during the operation of the clothes drying machine exceeds a preset threshold current threshold, it is determined that the clothes drying machine is in an abnormal operating state, such as rising obstruction, etc., and the clothes drying machine is controlled to start obstruction protection to prevent the clothes drying machine from being damaged by continued operation.

[0067] Among them, the current fluctuation value exceeds the obstruction current threshold, which may be that the current fluctuation value is greater than the set obstruction current threshold, or may be less than the set obstruction current threshold according to the size of the set obstruction current threshold, which is not limited in this application.

[0068] In this embodiment, the current fluctuation value of the clothes drying machine is detected. If the current fluctuation value exceeds a preset current threshold range, the resistance protection of the clothes drying machine is activated to protect the clothes drying machine.

[0069] According to the inventive concept of the present application, the steps of starting the obstruction protection of the clothes drying machine may be:

[0070] In response to the obstruction protection instruction of the clothes drying machine, a clothes drying machine reset program is called to control the clothes drying machine to fall back and reset.

[0071] In one embodiment, the obstruction protection of the clothes drying machine is activated to reverse the motor of the clothes drying machine, thereby controlling the clothes drying machine to fall back to the initial position to prevent the clothes drying machine from continuing to rise and being damaged, or causing the clothes drying machine to be blocked and stopped in mid-air, making it difficult for users to perform subsequent inspections and maintenance.

[0072] In another embodiment, a corresponding obstruction protection scheme can be activated according to the obstruction situation of the clothes drying machine. For example, the load state of the clothes drying machine motor is detected. If the load of the motor exceeds a preset safety value, the clothes drying machine motor is directly controlled to stop to prevent the motor from burning.

[0073] In the present application, when the clothes dryer triggers the obstruction protection, the clothes dryer can be reset or the motor can be stopped immediately according to the obstruction situation of the clothes dryer (for example, according to the motor load value). The clothes dryer can also be raised and lowered by a preset plan.

[0074] According to the inventive concept of the present application, the clothes drying machine obstruction protection method of the present application further includes the following steps:

[0075] S40: If the current fluctuation value in a single operation cycle of the clothes drying machine does not exceed the resistance current threshold and satisfies a preset resistance current threshold change condition, lower the resistance current threshold.

[0076] In one embodiment, the current fluctuation value of the clothes drying machine during the operation cycle is detected. If the clothes drying machine does not trigger the obstruction protection during the operation (that is, the current fluctuation value does not exceed the obstruction current threshold), it is further determined whether the clothes drying machine meets the obstruction current threshold change condition, so as to determine whether to adjust the obstruction current threshold corresponding to the current interval.

[0077] In this embodiment, the current fluctuation value of the clothes drying machine is obtained, and the current fluctuation value and the obstruction current threshold are compared according to the preset threshold change condition to determine whether the preset obstruction current threshold needs to be adjusted to avoid the difference between the current fluctuation value and the obstruction current threshold being too large to trigger the obstruction protection within the current range.

[0078] See also Figure 5 , Figure 5 A flowchart of the steps for determining whether a preset resistance current threshold change condition is met is provided for the first embodiment of the present application. In one embodiment, determining whether a preset resistance current threshold change condition is met includes the following steps:

[0079] S401, traversing the current fluctuation values ​​in a single operation cycle of the clothes drying machine to obtain the current fluctuation extreme value;

[0080] S402: If the current fluctuation extreme value does not exceed the preset current adjustment threshold, the preset resistance current threshold change condition is met.

[0081] The current fluctuation extreme value is the maximum value and / or minimum value of the current fluctuation value, and the preset current adjustment threshold is the trigger threshold for adjusting the resistance current threshold. For example, in one embodiment, the preset current adjustment threshold is half of the resistance current threshold, and the current fluctuation value is the maximum current fluctuation value. If the maximum current fluctuation value is less than the current adjustment threshold, the preset resistance current threshold change condition is met, and then the resistance current threshold corresponding to the current interval is adjusted.

[0082] Referring to the above embodiment, if the maximum current fluctuation value has not reached half of the preset obstruction current threshold, the difference between the current fluctuation value and the obstruction current threshold is too large, and the obstruction current threshold exceeds the normal current fluctuation range, making it difficult to trigger the obstruction protection of the clothes dryer. Therefore, through the preset obstruction current threshold change condition, the obstruction current threshold can be adjusted, thereby improving the accuracy of the clothes dryer triggering the obstruction protection.

[0083] In one embodiment, the resistance current threshold variation range may be preset by a user or a system, so that the resistance current threshold may be adjusted within the resistance current threshold variation range according to actual operating conditions.

[0084] The present application provides a method for preventing a clothes dryer from encountering an obstruction. The method divides a number of current intervals according to the starting current interval of the clothes dryer, sets different encountering an obstruction current thresholds for each current interval, obtains the encountering an obstruction current threshold corresponding to the interval according to the current interval in which the starting current value under different hanging weight conditions of the clothes dryer is located, detects the current fluctuation value during the operation of the clothes dryer and compares it with the encountering an obstruction current threshold, and starts the encountering an obstruction protection of the clothes dryer if the current fluctuation value exceeds the encountering an obstruction current threshold, so that the clothes dryer falls back and resets; at the same time, by judging whether the current fluctuation value meets the condition of the encountering an obstruction current threshold change, the encountering an obstruction current threshold corresponding to the current interval is dynamically adjusted to improve the accuracy of triggering the encountering an obstruction protection. The present application provides a method for preventing a clothes dryer from encountering an obstruction. The encountering an obstruction current threshold is selected according to different starting currents, so that the encountering an obstruction protection can be triggered more timely when the clothes dryer is hung with a small weight, and at the same time, the encountering an obstruction triggering threshold is increased under the condition of a large hanging weight, so as to avoid the problem of false triggering.
