[0002] For those with higher water consumption star ratings, the only option is to continuously reduce water consumption throughout the entire process. For lower residual PBIS, the only way to reduce the residual PBIS within the load is to increase the maximum spin speed mid-spin. The maximum spin speed cannot be reached. Furthermore, Australian energy efficiency loads are more diverse than those elsewhere, with nine types of loads in total. Large bath towels have strong water absorption and are prone to significant eccentricity at high spin speeds. Previous dehydration logic cannot meet the Australian energy efficiency requirements for maximum spin speed capability, making achieving the maximum spin speed in Australia extremely difficult and requiring urgent optimization and improvement.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear and distinct, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Exemplary Methods

[0047] like Figure 1 As shown, an embodiment of the present invention provides a dehydration method for a drum washing machine, and the dehydration method for the drum washing machine includes the following steps:

[0048] Step S100 , detecting the operating state of the drum washing machine, and obtaining a preset drainage strategy and dehydration strategy according to the operating state.

[0049] In this embodiment, the dehydration method of a drum washing machine is applied to a drum washing machine.

[0050] In this embodiment, the drum washing machine is provided with a corresponding gravity sensor, a drainage pump and a drum motor. When the drum washing machine starts the gravity sensor, the drainage pump and the drum motor, it runs corresponding program instructions, such as drainage instructions, dehydration instructions, rinsing instructions, etc.

[0051] Before implementing the dehydration method of the drum washing machine, it is also necessary to set corresponding operating instructions and operating strategies in the drum washing machine so that during the operation of the drum washing machine, drainage, pre-dehydration and main dehydration operations can be performed according to the operating instructions and operating strategies.

[0052] In one implementation of this embodiment, the following steps are included before step S100:

[0053] Step S001, setting the drainage strategy; the drainage strategy includes a first drainage state, a second drainage state and drainage time corresponding to each state;

[0054] Step S002, setting the dehydration strategy; the dehydration strategy includes pre-dehydration and main dehydration.

[0055] In this embodiment, the drum washing machine obtains a corresponding operating strategy according to the current operating state, wherein the current operating state is the state of just entering the drainage state or the state of just entering the dehydration state; the operating strategy includes: a drainage strategy and a dehydration strategy, specifically including the first drainage state and the second drainage state included in the drainage strategy, and the pre-dehydration and main dehydration included in the dehydration strategy.

[0056] In one implementation of this embodiment, step S100 includes the following steps:

[0057] Step S101, detecting the operating status of the drum washing machine;

[0058] Step S102, determining whether the operating state is a drainage operating state or a dehydration operating state;

[0059] Step S103: If it is the drainage operation state, obtain the preset drainage strategy;

[0060] Step S104: If it is the dehydration operation state, obtain a preset dehydration strategy.

[0061] In this embodiment, the operating state of the drum washing machine is first detected, and a corresponding strategy is obtained according to the current user-set operating program, wherein the strategy includes a drainage strategy and a dehydration strategy.

[0062] In this embodiment, the drum washing machine is provided with an operating program. The operating status of the drum washing machine can be determined by detecting the operating status of the operating program and the output power of the drum washing machine. After the operating status of the drum washing machine is determined, the drainage strategy and dehydration strategy pre-set in the drum washing machine chip are obtained.

[0063] In this embodiment, the dehydration strategy includes pre-spinning and main-spinning. After entering the dehydration process, a resting eccentricity test is performed before pre-spinning. After obtaining the resting eccentricity value, the speed of pre-spinning 1 is determined based on the resting eccentricity value range. After pre-spinning 1, the resting eccentricity value is retested to determine the speed of pre-spinning 2. After two pre-spinning cycles, the resting eccentricity value is measured again to determine whether the dehydration speed corresponding to the eccentricity value can reach the system-set main-spinning speed. If it can, the main-spinning process begins; if not, the pre-spinning process continues.

[0064] like Figure 1 As shown, in one implementation of the embodiment of the present invention, the dehydration method of the drum washing machine further includes the following steps:

[0065] Step S200 , controlling the state of the drainage pump and the holding time of the drum motor of the drum washing machine according to the drainage strategy.

[0066] In this embodiment, the drum washing machine's drainage strategy includes a first drainage state and a second drainage state. Based on the first and second drainage states, the drain pump state and the drum motor are alternately controlled to maintain a stationary state, draining for 1 minute or stopping drainage until the drainage operation is complete. Specifically, the strategy includes: turning on the drain pump, keeping the motor stationary, and draining for 1 minute; turning off the drain pump, keeping the motor stationary, and draining for 2 minutes; turning on the drain pump, keeping the motor stationary, and draining for 1 minute; turning off the drain pump, keeping the motor stationary, and draining for 2 minutes; and turning on the drain pump, keeping the motor stationary, and draining for 1 minute. These multiple drainage and stationary states are designed to remove as much water as possible from the drum. If drainage is incomplete, the moisture content of the load at the bottom of the drum will be significantly higher than that at the top of the drum, resulting in a larger OOB eccentricity test result. This may prevent the pre-spin OOB eccentricity limit from being reached, preventing spin operation.

[0067] In one implementation of this embodiment, step S200 includes the following steps:

[0068] Step S201, according to the first drainage state, the drainage pump is turned on and the drum motor is controlled to remain in a stationary state to drain water for 1 minute;

[0069] Step S202: According to the second drainage state, the drainage pump is controlled to be turned off, and the drum motor is controlled to remain in a stationary state for 2 minutes to stop drainage;

[0070] Step S203, according to the first drainage state and the second drainage state, alternately controlling the state of the drainage pump and keeping the drum motor in a stationary state to drain water for 1 minute or stop draining until the drainage operation state is completed.

[0071] In this embodiment, the first drain state of the drum washing machine is to turn on the drain pump, keep the motor in a stationary state, and drain for 1 minute; the second drain state is to turn off the drain pump and keep the motor in a stationary state for 2 minutes. The first and second drain states are alternately controlled to control the drum washing machine, and multiple drainage and static states are used to remove as much water as possible from the drum. If the drainage is not thorough, the moisture content of the load at the bottom of the drum will be much higher than that at the top of the drum, resulting in a relatively large OOB eccentricity value, which may not reach the OOB eccentricity limit for pre-spinning and prevent spinning. Therefore, the drum washing machine is alternately controlled by the first and second drain states until the static eccentricity value for pre-spinning 1 is reached.

[0072] In this embodiment, the drain pump is shut down and left to stand for 2 minutes in the second drainage state because the drain pump may be damaged if it is operated with very little water. Therefore, the drain pump is operated after standing for 2 minutes to protect the drum washing machine.

[0073] like Figure 1 As shown, in one implementation of the embodiment of the present invention, the dehydration method of the drum washing machine further includes the following steps:

[0074] Step S300: Perform the static eccentricity detection, and control the drum motor to perform pre-dehydration and main dehydration according to the detection result and the dehydration strategy.

[0075] In this embodiment, the dehydration strategy includes pre-dehydration and main dehydration. Pre-dehydration is used to remove excess water content so that the static eccentricity detection can reach the speed of the main dehydration.

[0076] In this embodiment, the two pre-spins can remove most of the water. At this time, the tested static eccentricity value is very close to the static eccentricity value at the highest speed, which can greatly improve the change of the static eccentricity value caused by the change of the rotational speed; in the main spin process, the acceleration of the rotational speed of the main spin is lower than that before the pre-spin. This is to prevent the main spin from causing water carryover due to excessive acceleration during the high-speed process; in the high-speed process, the maintenance time of several medium-high speed sections is lengthened. Taking a 1400rpm drum washing machine as an example, the maintenance time at 800rpm is increased to 90 seconds, the maintenance time at 1000rpm is increased to 90 seconds, and the maintenance time at 1210rpm is increased to 90 seconds. This is to allow the water to be drained as much as possible during the maintenance stage. If the drainage is not thorough enough, water carryover will occur in the next high-speed stage.

[0077] In one implementation of this embodiment, step S300 includes the following steps:

[0078] Step S301, performing the static eccentricity detection to obtain a first static eccentricity value of the drum washing machine;

[0079] Step S302, determining whether the first static eccentricity value is the eccentricity value corresponding to the first pre-dehydration;

[0080] Step S303: If the eccentricity value is the eccentricity value corresponding to the first pre-dehydration, the rotation speed of the drum motor is controlled to be 400 rpm to perform the first pre-dehydration.

[0081] In one implementation of this embodiment, the following steps are included after step S303:

[0082] Step S304, performing a static eccentricity detection to obtain a second static eccentricity value of the drum washing machine;

[0083] Step S305, determining whether the second static eccentricity value is the eccentricity value corresponding to the second pre-dehydration;

[0084] Step S306: If the eccentricity value is the eccentricity value corresponding to the second pre-dehydration, the rotation speed of the drum motor is controlled to be 400 rpm to perform the second pre-dehydration.

[0085] In this embodiment, two pre-spins are provided to further reduce the moisture content within the load. This lowering of the moisture content within the load reduces the larger static eccentricity caused by different water absorption, making it easier to reach the static eccentricity value at the highest speed. The drum washing machine system is pre-set with a first static eccentricity value corresponding to the first pre-spin and a second static eccentricity value corresponding to the second pre-spin.

[0086] Step S307, obtaining the static eccentricity value and weight value after the second pre-dehydration;

[0087] Step S308, determining whether the static eccentricity value and the weight value both meet the main dehydration condition;

[0088] Step S309: If both the static eccentricity value and the weight value meet the main dehydration conditions, the drum motor is controlled to perform the main dehydration action according to the preset main dehydration speed; wherein the preset main dehydration speed is based on the initial main dehydration speed and increases the preset value in sequence to gradually increase the speed of the drum motor.

[0089] In this embodiment, before the main spin cycle, the eccentricity value before the main spin cycle is determined to be within the permissible eccentricity range for the load weight, ensuring that the washing machine completes the spin cycle within normal vibration and noise levels. This prevents forced high-speed spin cycles due to increased moisture content. If the eccentricity value and weight are excessive, exceeding the maximum set limits, the main spin cycle cannot proceed. Ultimately, the main spin cycle proceeds based on the eccentricity and weight values ​​meeting these conditions, ensuring stable vibration throughout the machine.

[0090] In another implementation of this embodiment, the following steps are further included before step S301:

[0091] Step S301a, obtaining the static eccentricity value and weight value of the drum washing machine after the drainage operation is completed;

[0092] Step S301b: setting the eccentricity range and pre-spin speed of the drum washing machine according to the static eccentricity value and the weight value.

[0093] In this embodiment, the design distinguishes different speed gears according to the eccentricity value and the weight value. The eccentricity range for dehydration corresponding to the weight value range in the preset correspondence includes multiple eccentricity range gears, and each eccentricity range gear corresponds to a different dehydration speed. The control method also includes:

[0094] When the second static eccentricity value is within the preset eccentricity range, it is further determined that the second static eccentricity value is within the eccentricity range gear for dehydration in the preset corresponding relationship;

[0095] Determining the main spin speed of the washing machine according to the spin speed corresponding to the eccentric range gear;

[0096] Control the washing machine to run at a predetermined spin speed for a preset spin time.

[0097] If the weight coefficient is not within the preset weight coefficient range, it is necessary to determine whether to perform dehydration at the same speed as the original dehydration speed to extend the dehydration time, or to further increase the speed based on the original dehydration speed. Generally speaking, after dehydration, the clothes will re-enter the eccentricity detection stage, and their eccentricity value will change. If the eccentricity value at this time meets the eccentricity limit of high speed, the speed can be increased to dehydrate again. If the eccentricity value does not meet the eccentricity limit of high speed, the speed will be increased to the original dehydration speed and the dehydration time will be extended. Specifically, when the second static eccentricity value meets the setting conditions for high-speed dehydration, the dehydration speed of the washing machine is restored to the original dehydration speed and the dehydration speed is further increased to continue dehydration; when the second static eccentricity value does not meet the setting conditions for high-speed dehydration, the dehydration speed of the washing machine is restored to the original dehydration speed and the dehydration is continued.

[0098] Further optionally, the eccentricity values ​​in the plurality of eccentricity range gears increase in sequence, and the dehydration speeds corresponding to the plurality of eccentricity range gears decrease in sequence; Figure 2 As shown in the flow chart, when the second static eccentricity value meets the setting conditions for high-speed dehydration, the dehydration speed of the washing machine is restored to the original dehydration speed and then the dehydration speed is further increased to continue dehydration; when the second static eccentricity value does not meet the setting conditions for high-speed dehydration, the dehydration speed of the washing machine is restored to the original dehydration speed and then dehydration is continued.

[0099] This embodiment adopts the above technical solution to achieve the following effects:

[0100] This embodiment detects the operating status of a drum washing machine and, based on that status, determines a pre-set drainage and dehydration strategy. It also controls the status of the drum washing machine's drain pump and the drum motor's hold time based on the drainage strategy. It then performs a static eccentricity test and, based on the test results and the dehydration strategy, controls the drum motor to perform pre-spin and main spin operations. This embodiment, through the pre-set drainage and dehydration strategies, reduces the difference between the OOB eccentricity value at maximum speed and the OOB eccentricity value measured at low speeds, enabling the drum washing machine to meet Australian energy efficiency requirements for maximum spin speed capability.
