Description

Technical Field

[0001] This invention belongs to the field of washing equipment, and particularly relates to a control method, control device and washing equipment for washing equipment. Background Technology

[0002] Washing machines are an essential household appliance with a very high penetration rate. During washing machine use, it's inevitable that a washing program will be started but detergent will be left in, and this usually isn't discovered until the entire washing cycle is complete. In most cases, users will choose to perform a second wash, which inevitably leads to wasted time and energy, as well as damage to clothes from repeated washing.

[0003] Related technologies disclose washing machines equipped with detergent residue detection devices (pH detection devices). These devices detect detergent residue data at different washing stages to reduce detergent residue in clothes. Alternatively, the detergent dispensing process and washing stages can be controlled based on the relationship between the pH value of the water inside the drum and a set pH threshold. Similarly, the rinsing process can be controlled, thereby improving the user experience by enabling the washing machine to dispense detergent according to the degree of soiling of the clothes and to control the number of rinses and rinsing time.

[0004] Existing technical solutions do not address the situation where users fail to add detergent. In this case, not only will the intended purpose of cleaning clothes not be achieved, but there will also be a waste of time and energy due to secondary washing. Summary of the Invention

[0019] Pause the washing program and start the timer;

[0020] If no new start command is received within the first set time period, the washing program for which detergent was not added will be started.

[0021] Alternatively, if a new start command is received within the first set time period, the washing program corresponding to the new start command is run.

[0022] A second aspect of the present invention provides a control device for a washing apparatus, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement the method according to any one of the first aspects.

[0031] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0032] In the description of this invention, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] To address the issue of users accidentally leaving detergent in the washing equipment, a first aspect of this invention provides a control method for a washing device. The washing equipment includes a washing chamber for accommodating laundry, and a first detection device is provided at the bottom of the drum. This first detection device monitors characteristic values ​​of the washing water within the drum, such as pH value or conductivity. Figure 1 The control methods include S1 to S3, wherein:

[0035] S1, after starting the washing program, determine the characteristic value of the clean water, obtain the characteristic detection value of the washing water in the drum, and record the detection time;

[0036] S2, compare the difference between the feature detection value and the clean water feature value with the set threshold, and compare the detection time with the set detection time;

[0037] S3, in PH 内 -PH 初 ≤ΔPH, and T 采 >T 设 When the current washing mode is determined to be a detergent overfilling mode, a warning is issued.

[0038] Among them, PH 内 Represents the feature detection value, PH 初 The values ​​represent the characteristics of clean water, ΔPH represents the set threshold, and T represents the characteristic value of clean water. 采 T represents the detection duration. 设 This indicates the set detection duration.

[0039] Specifically, due to significant differences in water quality across regions, and without knowing the final sales region of the washing equipment, this embodiment requires confirmation of the clean water characteristic value. Specifically, the washing equipment can communicate with a terminal or server to obtain the clean water characteristic value; alternatively, the washing equipment can communicate with devices in a home IoT system, and these devices are equipped with a detection device for the clean water characteristic value, such as a pH detection device or a conductivity detection device, to obtain the clean water characteristic value; or the washing equipment's water inlet is equipped with a detection device to detect the characteristic value of the water at the inlet, and the detection value of this device is used as the clean water characteristic value.

[0040] Taking a drum washing machine as an example, a pH detection device is placed at the bottom of each inner drum to monitor the pH value of the wash water in real time. When the user starts a washing mode (excluding rinsing, drying, and drum cleaning modes that do not require detergent), after the water inlet pipe begins to supply water normally, the pH detection devices located at the water inlet and the bottom of the inner drum begin to collect pH values ​​and record the real-time duration of the collection (T). 采 These real-time data are used to perform a series of conditional judgments to determine whether the situation falls under the normal detergent dosing mode or the detergent misdosing mode, thereby selecting the appropriate subsequent treatment procedure. The pH value at the water inlet is recorded as pH. 初 The pH value of the water at the bottom of the inner cylinder is recorded as pH. 内 ΔPH is a set threshold determined after comprehensively considering the accuracy of the detection device and the measured data, T 设 A fixed value set at the factory or a duration that can be freely set by the user to determine the data collection period; the specific determination conditions are as follows: T is satisfied. 采 >T 设 And pH 内 -PH 初 If the pH value is ≤ΔPH, it is determined that detergent has been omitted, and a warning will be issued.

[0041] This embodiment compares the characteristic detection value of the water in the washing chamber with the characteristic value of local clean water, and combines the detection time to confirm whether the user has added detergent. It promptly reminds the user to save time and energy, avoid the waste of time and energy caused by secondary washing, protect clothes, save energy and protect the environment, and avoid damage to the color and fabric of clothes caused by repeated washing.

[0042] Further, optionally, combined Figure 2 The control method also includes the following steps:

[0043] In PH 内 -PH 初 >ΔPH, and T 采 ≤T 设 When this happens, the current washing mode is determined to be the detergent dispensing mode.

[0044] Alternatively, the control method may further include the following steps:

[0045] In PH 内 -PH 初 ≤ΔPH, and T 采 ≤T 设 If the time is not met, the characteristic values ​​of clean water and the characteristic detection values ​​of the washing water in the drum are re-acquired, and the difference between the characteristic detection value and the clean water characteristic value is compared with the set threshold, and the detection time is compared with the set detection time.

[0046] Specifically, after the user starts the washing mode, the system needs to confirm the local clean water characteristic value. Simultaneously, the washing equipment begins working, collecting the characteristic value of the water inside the drum, calculating the difference between the two values, and recording the real-time collection duration (detection duration). This difference is compared to a set threshold, and the detection duration is compared to a set detection duration to determine whether it falls under the category of normal detergent dispensing or detergent leakage, thus selecting the appropriate subsequent processing procedure. The specific judgment criteria are as follows:

[0047] 1. Meets pH requirements 内 -PH 初 If the pH value is greater than ΔPH, it is determined that detergent has been added, and the normal washing procedure should continue.

[0048] 2. Satisfying T 采 ≤T 设 And pH 内 -PH 初 If the pH value is ≤ΔpH, then pH should be collected again. 初 and PH 内 And make another judgment;

[0049] 3. Satisfy T 采 >T 设 And pH 内 -PH 初 If the pH value is ≤ΔPH, it is determined that detergent has been omitted, and a warning will be issued.

[0050] Preferably, a second detection device is provided at the water inlet of the washing equipment to detect the characteristic value of the water at the water inlet, and the characteristic value of the water at the water inlet detected by the second detection device is used as the characteristic value of clean water.

[0051] Alternatively, the control method may further include the following steps:

[0052] The threshold is related to the detergent concentration, detergent dosage, the accuracy of the first detection device and its detection results, and the accuracy of the second detection device and its detection results.

[0053] Specifically, it is understood that different types of detergents have different concentrations and pH values, and the amount of detergent added and the accuracy of the detection device also affect the detection results. Therefore, in this embodiment, the set threshold ΔPH is an empirical value determined by comprehensively considering the detergent type, the amount of detergent added, and the accuracy and measured data of the two detection devices mentioned above. Furthermore, considering that users may not accurately add the required type and amount of detergent during laundry, it is preferable to use the tolerance value determined by the accuracy of the two devices and their measured data as the set threshold. In addition, considering the user's need for precise laundry care, under experimental conditions, with the detection device unchanged, the set threshold corresponding to different combinations of detergent dosage and detergent type can be determined. During laundry, the user can determine the detergent type through the washing program; for example, cotton and wool require different detergents. Additionally, the automatic detergent dispensing device can be used to obtain the dosage, thereby determining the set threshold for the current wash.

[0054] Alternatively, after issuing the warning, the control method may further include the following steps:

[0055] Pause the washing program and start the timer;

[0056] If no new start command is received within the first set time period, the washing program for which detergent was not added will be started.

[0057] T 警 The warning duration, i.e., the first set duration, is a washing program for when detergent is not added. The user will receive a warning within T... 警 If there is no response within a certain time, the washing program for which detergent was not added will be started. For example, the washing machine will stop running, a message indicating that no detergent has been added will be displayed on the screen, and a warning message will be issued on time to help users find out that detergent was not added during this wash.

[0058] Alternatively, if a new start command is received within the first set time period, the washing program corresponding to the new start command is run.

[0059] Specifically, T 警 The duration of the warning notification, i.e., the first set duration, is when the user... 警 If a response is received within a specified time, the washing program will restart according to the user's new settings. Understandably, after entering a new washing program or restarting the current washing program, it is also necessary to confirm whether the user has added detergent. If it is found that the user has started the washing program but forgot to add detergent, a warning will be issued first. If no response is received within a certain time, the washing program for which detergent was forgot to be added will be processed.

[0060] The above implementation plan uses a drum washing machine as an example. This technical solution can also be applied to other appliances that use water and detergent to clean objects during operation, such as dishwashers and shoe washing machines.

[0061] A second aspect of the present invention provides a control device for a washing apparatus, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement the method according to any one of the first aspects.

[0062] A third aspect of the present invention provides a washing apparatus that employs any of the methods of the first aspect, or includes the control device of the second aspect.

[0063] Alternatively, the washing equipment may include garment handling equipment, dishwashers, and shoe washing machines.

[0064] This invention can further ensure the intended purpose of washing clothes, promptly remind users to avoid the waste of time and energy caused by secondary washing, and at the same time avoid damage to the color and fabric of clothes caused by repeated washing, thereby achieving the purpose of saving energy and being environmentally friendly.
