[0002] During the washing process, different clothing loads have different washing requirements. During the standard washing process of large clothes in a pulsator washing machine, the water flow is weakened by the large clothing load, making it impossible to reversely flush the clothes during the entire washing process. The washing appears to be weak, which reduces the washing effect. Therefore, the water flow activity intensity of the pulsator washing machine remains unchanged during the standard washing program, which will lead to poor washing effect of the clothes to be washed in the pulsator washing machine.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in the description of the present invention, the meaning of "multiple" and "several" is at least two, for example two, three, etc., unless otherwise clearly and specifically defined.

[0036] See also Figure 1 As shown, the present invention is a method for adaptively controlling the load capacity of a pulsator washing machine motor, comprising the following steps:

[0037] S10. According to the type of laundry load, the preset standard water flow and motor operation basic temperature data of the pulsator washing machine under the standard washing state are saved.

[0038] The method for saving the preset standard water flow and motor operation basic temperature data in this step is: when the pulsator washing machine is at the maximum clothing load and the preset standard water flow Sv is used, start the collection program; record the temperature change rate T1, T2, T3...Tn of the internal coil of the motor according to the set collection frequency and number of samples; save the collected temperature change rate data as the motor operation basic temperature data in the storage system of the pulsator washing machine.

[0039] In this step, the temperature change rate data of the internal coil of the motor is recorded according to the set collection frequency and number of samples. The collection frequency is set to be collected once every 5 to 80 seconds. The set number of samples is determined based on the operation cycle of the pulsator washing machine and the temperature change characteristics of the motor. The number of samples n is determined.

[0040] It should be understood that different types of laundry loads correspond to different standard washing requirements. This application mainly solves the problem that during the maximum laundry load washing process, the standard washing intensity cannot meet the customer's needs to adjust a stronger laundry water flow.

[0041] S20, collecting real-time temperature data of the motor of the pulsator washing machine in the strong washing state.

[0042] The method for collecting the real-time temperature data of the motor operation in this step is: the pulsator washing machine starts strong washing, and during the washing process, the temperature change rate data of the internal coil of the motor is collected in real time, and the collected temperature change rate data is marked as T'1, T'2, T'3...T'n, wherein the real-time temperature data of the motor operation T'1, T'2, T'3...T'n correspond one to one with the basic temperature data of the motor operation T1, T2, T3...Tn.

[0043] It needs to be understood that the appropriate temperature measurement method should be selected according to the actual situation and needs of the motor; for occasions requiring real-time monitoring and high-precision measurement, the infrared temperature measurement method or the temperature measurement element method can be considered; for occasions with low cost and low precision requirements, the resistance method can be considered; therefore, the temperature changes of the internal coils of the motor can be collected through a variety of methods; in actual applications, the appropriate temperature measurement method should be selected according to the specific situation and needs of the motor, and corresponding measures should be taken to ensure the accuracy and reliability of the temperature measurement results.

[0044] S30, analyzing and comparing the real-time temperature data of the motor operation with the basic temperature data of the motor operation, and dynamically adjusting the washing water flow.

[0045] Combination Figure 2 As shown, the sub-steps of the method for dynamically adjusting the washing water flow in step S30 are:

[0046] S31. Determine whether the set conditions are met, compare the real-time temperature data of the motor operation with the basic temperature data of the motor operation with the same serial number, check whether the real-time temperature data of the motor operation at m consecutive collection points are all lower than the basic temperature data of the motor operation, and the difference is greater than the preset safety temperature difference △t. If the set conditions are met, execute step S32; if it is determined that the set conditions are not met, execute step S40 of washing according to the preset standard water flow.

[0047] In this step, the value range of the continuous m collection points is 2-15; the preset safety temperature difference △t is set according to the thermal characteristics of the motor, the design of the washing machine and the safety requirements of the user; the value of △t should ensure that the motor can still maintain safe operation when the motor temperature change rate is lower than the basic data.

[0048] S32, dynamically adjust the washing intensity to increase the washing water flow to a preset level.

[0049] In this step, when the washing intensity is dynamically adjusted to increase to the preset gear and the washing water flow is operated, the motor forward time is increased as set, or the motor reverse time is increased as set, or the motor stop time is shortened as set; wherein, when the motor forward time is increased as set, a longer forward time helps to distribute the clothes more evenly in the water, reduces entanglement and dead corners, and improves washing uniformity; when the motor reverse time is increased as set, reversal helps to loosen the clothes and avoid excessive entanglement during the washing process, thereby protecting the clothes and reducing wear; when the motor stop time is shortened as set, the total time of the washing cycle is shortened, thereby completing the washing task in a shorter time and helping to reduce energy consumption.

[0050] S33, determine whether the preset maximum washing water flow is reached. If the washing water flow intensity at the preset gear has not reached the maximum washing water flow threshold, loop through steps S31 to S33 until the washing water flow intensity at the preset gear reaches the maximum washing water flow threshold, then execute step S34.

[0051] S34, washing is performed according to the preset maximum washing water flow.

[0052] During the dynamic adjustment of the washing water flow, the above-mentioned temperature change rate data comparison and washing water flow intensity dynamic adjustment process are repeated in a cycle. After each adjustment of the water flow intensity, re-monitoring and comparison are performed. If the washing water flow has been enhanced to the maximum water flow set in the program, further enhancement will be stopped. In addition, if the user chooses to exit the strong washing program during the washing process, the washing water flow intensity will be restored to the standard washing state.

[0053] By adopting the adaptive control method of the present application, adaptive automatic adjustment of the washing intensity of a pulsator washing machine can be achieved. The purpose is to dynamically adjust the washing water flow when the washing load changes, so that the washing machine has a higher washing intensity output to meet the requirements of washing different clothing loads. In addition, the real-time temperature of the motor is detected, and during the dynamic adjustment of the washing water flow, the safe operation of the motor can be maintained to meet the safety temperature rise requirements.
