Description

Technical Field

[0001] The present application relates to the field of parameter control, and in particular, to a parameter control method, controller, and device for laundry processing equipment. Background Art

[0002] Controlling the eccentricity of drum washing machines has long been a research focus. To address the significant vibration caused by uneven distribution of laundry, the industry has employed a method that calculates the eccentricity value at lower speeds.

[0003] During the long-term use of the washing machine, the internal structure of the washing machine wears out and the electrical parameters drift, resulting in an estimated deviation of the eccentricity value, which deviates greatly from the eccentricity set value and causes control failure.

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings 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 in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] According to an embodiment of the present application, an embodiment of a parameter control method for a laundry processing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] like Figure 1 As shown, the method includes the following steps:

[0039] S101. Obtain target parameters transmitted by the laundry processing equipment in at least one operation phase.

[0040] Wherein, the target parameter includes at least one of an eccentricity value or a weighing value.

[0041] In one embodiment, the laundry processing device has multiple operating stages, such as a washing stage and a spin stage. Furthermore, the spin stage can be divided into multiple operating stages, such as a pre-spin speed increase stage and a post-spin speed increase stage, each of which can be considered an operating stage of the laundry processing device. When acquiring target parameters, the target parameter for at least one operating stage is acquired. The specific parameters are determined by the user. For example, if frequently used parameters are to be controlled, an acquisition cycle can be set, and the target parameter for each operating stage is acquired after each acquisition cycle.

[0042] In one embodiment, the target parameter may include an eccentricity value and a weighing value. In order to more accurately control the parameters of the laundry processing equipment, taking the eccentricity value as an example, the eccentricity value can also be divided into an eccentricity value when the speed is not successfully increased and an eccentricity value when the speed is successfully increased. Among them, the eccentricity value when the speed is not successfully increased refers to the eccentricity value that does not meet the preset eccentricity value condition for the speed increase after the eccentricity value is generated; that is, before the rotation speed of the processing barrel of the laundry processing equipment reaches the speed threshold, the eccentricity value greater than the eccentricity threshold is the eccentricity value when the speed is not successfully increased. The eccentricity value when the speed is successfully increased refers to the eccentricity value that meets the preset eccentricity value condition for the speed increase after the eccentricity value is generated; that is, after reaching the speed threshold, the eccentricity value less than the eccentricity threshold is the eccentricity value when the speed is successfully increased. The situation of the weighing value is the same as that of the eccentricity value, and will not be repeated.

[0043] In addition, the target parameters may also include a power value when the speed of the processing barrel is increased and a power value when the processing barrel is in a stable state after the speed is increased.

[0044] S102: adjusting a target limit value corresponding to the target parameter based on a current operation stage of the laundry processing apparatus according to a variation of the target parameter.

[0045] The target limit value is used to constrain the control strategy of the target parameter on the laundry processing equipment.

[0046] In one embodiment, after obtaining the target parameter, the variation range can be determined using the eccentricity value or weighing value in the target parameter. The variation range can be determined by comparing the eccentricity value in the target parameter with a preset set value to obtain the variation range. The variation range can also be determined by performing a relational operation on the eccentricity value in the target parameter.

[0047] The variation range can be determined based on the variation range, and then the target limit value can be adjusted according to different operation stages, so that the laundry processing device compares the eccentricity value with the adjusted target limit value to obtain a corresponding control strategy.

[0048] For ease of understanding, taking a washing machine as an example, when a washing machine has been used for a long time, the internal mechanical structure is severely worn, and the electrical parameters of related electrical components also drift. At this time, the eccentricity value calculated by the washing machine is less accurate. If the washing machine still compares the eccentricity value with the target limit value set at the factory, when the eccentricity value exceeds the target limit value, it is considered that the processing drum is difficult to speed up to the target speed, and a control strategy of reducing the target speed is executed, which will cause subsequent control to be inconsistent with the actual situation, resulting in control failure. When this embodiment determines that the eccentricity value calculated by the washing machine has a large change range, the target limit value is adjusted so that the target limit value is more compatible with the calculated eccentricity value, so that the subsequent control strategy of the washing machine is more in line with the actual situation.

[0049] Through the above steps, since the target limit value is adjusted, it is unlikely that a large deviation will occur between the target parameter and the target limit value, thereby ensuring effective control of the laundry processing equipment based on the target limit value.

[0050] In another embodiment of the present application, adjusting the target limit value corresponding to the target parameter based on the current operation stage of the laundry processing equipment according to the change amplitude of the target parameter includes:

[0051] Based on the current operation stage of the laundry treatment device, the target limit value of the target parameter is increased or decreased by utilizing the change range of the target parameter.

[0052] In one embodiment, the target limit value is increased or decreased by the change amplitude. For example, when the target limit value needs to be decreased, the target limit value is decreased by a value corresponding to the change amplitude; when the target limit value needs to be increased, the target limit value is increased by a value corresponding to the change amplitude.

[0053] Through the above steps, when adjusting the target limit value, directly using the calculated change range helps to reduce calculation requirements and save computing resources.

[0054] In another embodiment of the present application, the increasing or decreasing the target limit value of the target parameter by utilizing the variation range of the target parameter based on the current operation stage of the laundry processing device includes:

[0055] When the laundry processing device is currently operating in a dehydration stage, if the ratio of the power to the eccentricity value in the target parameter is greater than a preset proportional setting value, reducing the target limit value by the variation range;

[0056] When the laundry processing device is currently operating in a dehydration stage, if the ratio of the power to the eccentricity value in the target parameter is less than or equal to a preset proportional setting value, increasing the target limit value by the variation range;

[0057] When the laundry processing device is currently operating in a non-dehydration stage, if the ratio of the power to the eccentricity value in the target parameter is greater than a preset proportional setting value, increasing the target limit value by the variation range;

[0058] When the laundry processing device is currently operating in a non-dehydration stage, if the ratio of the power to the eccentricity value in the target parameter is less than or equal to a preset proportional setting value, the target limit value is reduced by the variation range.

[0059] In one embodiment, the dehydration stage refers to a normal dehydration stage, that is, a dehydration stage when water inflow parameters such as water inflow volume and water inflow time are all within a normal range.

[0060] In one embodiment, the non-dehydration stage is a stage when the laundry processing equipment is not performing dehydration, such as a washing stage, a water intake stage, etc.

[0061] Through the above steps, the operation phase is divided into a dehydration phase and a non-dehydration phase, which helps to adjust the target limit value according to the eccentricity value in the dehydration phase, thereby ensuring smooth dehydration.

[0062] In another embodiment of the present application, the increasing or decreasing the target limit value of the target parameter by utilizing the variation range of the target parameter based on the current operation stage of the laundry processing device includes:

[0063] When the laundry processing device is currently operating in a dehydration stage, if the ratio of the power to the weighing value in the target parameter is greater than a preset proportional setting value, reducing the target limit value by the variation range;

[0064] When the laundry processing device is currently operating in a dehydration stage, if the ratio of the power to the weighing value in the target parameter is less than or equal to a preset proportional setting value, increasing the target limit value by the variation range;

[0065] When the laundry processing device is currently operating in a non-dehydration stage, if the ratio of the power to the weighing value in the target parameter is greater than a preset proportional setting value, increasing the target limit value by the variation range;

[0066] When the laundry processing device is currently operating in a non-dehydration stage, if the ratio of the power to the weighing value in the target parameter is less than or equal to a preset proportional setting value, the target limit value is reduced by the variation range.

[0067] Through the above steps, the operation stage is divided into the dehydration stage and the non-dehydration stage, which helps to adjust the target limit value according to the weighing value in the dehydration stage, thereby ensuring smooth dehydration.

[0068] In another embodiment of the present application, the power in the target parameter is an average power value of the laundry processing device when the speed is stable in the current operation stage.

[0069] In one embodiment, if Figure 2 As shown, for example, if the eccentricity detection speed is 93 revolutions, which is the last stable speed stage, the average power value during the stable period of 93 revolutions is taken; if the dehydration speed is 400 revolutions, which is the last stable speed stage, the average power value during the stable period of 400 revolutions is taken.

[0070] Through the above steps, the accuracy of the power is improved by calculating the average value.

[0071] In another embodiment of the present application, the method further comprises:

[0072] The change range of the target parameter is calculated using each eccentricity value, maximum eccentricity value and minimum eccentricity value in the target parameter, or the change range of the target parameter is calculated using each weighing value, maximum weighing value and minimum weighing value in the target parameter;

[0073] The change amplitude is determined according to the difference between the change amplitude and a preset change setting value.

[0074] In another embodiment of the present application, the step of calculating the change range of the target parameter using the respective eccentricity values, the maximum eccentricity value, and the minimum eccentricity value in the target parameter, or the step of calculating the change range of the target parameter using the respective weighing values, the maximum weighing value, and the minimum weighing value in the target parameter, includes:

[0075] The variation range corresponding to the eccentricity value is calculated using the following formula;

[0076] M = (Omax - Omin) / ave (O1 + O2 + ... On); where M is the amplitude of change, Omax is the maximum eccentricity value, Omin is the minimum eccentricity value, On is the n eccentricity values ​​in the target parameter, and n is a positive integer;

[0077] The variation range corresponding to the weighing value is calculated using the following formula:

[0078] F = (Kmax - Kmin) / ave (K1 + K2 + ... Kt); where F is the amplitude of change, Kmax is the maximum weighing value, Kmin is the minimum weighing value, Kt is the t weighing values ​​in the target parameter, and t is a positive integer.
