Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and particularly relates to a washing machine water level adjustment method and a washing machine. Background Art

[0002] The fuzzy water level control of the pulsator fully automatic washing machine is preset in batches in the factory. The preset fuzzy water level cannot meet the personalized needs of users. How to set the water level that meets the user's usage habits is an urgent problem to be solved by technical personnel in this field.

[0003] In the prior art, for example, the invention patent with application number CN116043477A discloses a method, device, equipment and storage medium for determining the water level of a washing machine, the method comprising: obtaining a first weighing value of the washing machine, wherein the first weighing value includes a reference weighing value of the washing machine in an empty barrel state and a load weighing value of the washing machine in a non-empty barrel state, and the weighing value is the number of electrical signals generated when the washing machine performs a weighing function; determining a weighing value demarcation point according to the indicated capacity and water level of the washing machine; calculating a weighing interval determination value of each water level according to the weighing value demarcation point and the first weighing value, wherein the weighing interval is a range of weighing values ​​corresponding to each water level, and the weighing interval determination value is a boundary value of the weighing interval; determining a target water level corresponding to the target load according to a second weighing value of the washing machine weighing the target load and the size relationship between the weighing interval determination value. The method for determining the water level of the washing machine in the application can determine different water levels according to different loads, but does not take into account the user's adaptive adjustment of the water level and cannot meet the user's personal water level adjustment habits.

[0004] For another example, the invention patent with application number CN202211631718.1 discloses a fuzzy water level judgment method, device and storage medium based on a pulsator washing machine, which relates to the field of clothing washing technology. The method includes: in a waterless state, driving the motor of the pulsator washing machine to rotate forward and reverse to obtain the back electromotive force pulse value in real time; extracting the washing water level value according to a preset water level-pulse number comparison table, a preset empty barrel pulse reference value and the back electromotive force pulse value, wherein the water level-pulse number comparison table is used to record the corresponding relationship between the empty barrel pulse reference value, the back electromotive force pulse value and the washing water level value; and driving the pulsator washing machine to enter water for washing according to the washing water level value. By adopting the present invention, the washing water level value can be determined according to the back electromotive force pulse value detected in real time, thereby effectively solving the problem of automatically judging that the water level is low after the washing machine has been used for a long time. However, this method does not take into account that different users have different washing machine usage habits, and cannot further meet the personalized needs of users.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0031] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] The water level in the washing machine is set at the factory and cannot meet the user's personalized needs. Moreover, as the machine is run-in during use or the belt becomes loose, the relationship between the water level and power in the washing machine will change with the number of uses. How to adjust the relationship between the water level and power in the washing machine so that the relationship between the water level and power in the washing machine matches the user's personal usage habits is a technical problem that needs to be urgently solved by technical personnel in this field.

[0035] The present invention discloses a method for adjusting the water level of a washing machine. A water level-power comparison table is preset in the washing machine before leaving the factory. Before the washing machine starts the washing process, the user adjusts the water level to meet his or her expectations according to the quantity and type of clothes in the washing machine. However, the relationship between the water level and the power in the water level-power comparison table preset in the washing machine cannot meet the actual needs of the user. The present invention uses a method for adjusting the water level of a washing machine to adjust the relationship between the water level and the power of the washing machine, so that the washing machine meets the use needs of the user, conforms to the use habits of the user, and improves the use experience of the user.

[0036] It should be noted that the method for obtaining the water level-power comparison table is as follows: when the washing machine is in a waterless state, the back electromotive force pulse value is obtained in real time by reversing the motor; the washing water value is determined according to the preset pulse value to form a water level-pulse number comparison table; and then a comparison table of different water levels and powers is recorded, which is recorded as a water level-power comparison table.

[0037] Furthermore, the step of obtaining the water level-power comparison table includes: driving the pulsator washing machine to enter the intelligent fuzzy mode in a waterless state; in the intelligent fuzzy mode, driving the motor of the pulsator washing machine to repeatedly perform forward and reverse operations until the number of forward and reverse operations reaches a preset number; during the forward and reverse operations, real-time detection of the back electromotive force pulse value when the pulsator washing machine is reversed.

[0038] Next, the present invention is described in detail with reference to specific embodiments.

[0039] Embodiment 1

[0040] As an embodiment of the present invention, Figure 1 As shown, this embodiment discloses a method for adjusting the water level of a washing machine, wherein the washing machine is pre-installed with a water level-power comparison table, and the washing machine records the correspondence between the water level and the power when working, and adjusts the water level-power comparison table according to the recorded correspondence between the water level and the power, and adjusts the water level-power comparison table according to the latest generated water level-power comparison table, to ensure that the water level-power relationship of the washing machine during subsequent work is compatible with the user's usage habits, to ensure the washing efficiency of the washing machine, and to improve the user's usage experience.

[0041] Furthermore, during the operation of the washing machine, the power operation data of the washing machine at any water level is recorded, and the water level-power comparison table of the washing machine is adjusted according to the power operation data of the washing machine at the water level, thereby simplifying the updating process of the power comparison table. The washing machine can select any water level as the target water level, record the power operation data of the washing machine at the water level, and then adjust the relationship between water level and power in the water level-power comparison table at the water level accordingly.

[0042] Furthermore, the washing machine adjusts the water level-power relationship in the water level-power table in turn according to the frequency of use of different water levels during use. The washing machine gradually adapts to the user's usage habits and finally forms a water level-power comparison table suitable for the user.

[0043] Furthermore, the power operation data at any water level may be a power operation curve of the washing machine during washing, or may be an average value of the power operation of the washing machine at any water level. The power operation data with the smallest error may be recorded according to different use environments.

[0044] Furthermore, multiple water level-power data of the washing machine are continuously recorded, and the weighted average of the multiple water level-power data is performed to generate the latest water level-power comparison table. According to the weighted average water level-power comparison table of multiple water levels, the previously set water level-power relationship of the washing machine is adjusted to reduce the number of times the washing machine is used. While ensuring that the water level-power relationship of the washing machine during operation conforms to the actual condition of the washing machine, the number of uses is reduced to avoid adjustment errors caused by water level fluctuations due to belt loosening, etc.

[0045] Embodiment 2

[0046] As an embodiment of the present invention, this embodiment further improves the adjustment method of the water level-power comparison table based on the first embodiment. The details are as follows:

[0047] In this embodiment, if Figure 2 As shown, the adjustment steps of the washing machine to adjust the water level power comparison table of the washing machine according to the recorded power operation data are as follows:

[0048] S1: Use the power operation data recorded at any water level to replace the power data of the corresponding water level in the water level-power comparison table;

[0049] S2: Calculate the rate of change of power at this water level;

[0050] S3: Adjust the power of the remaining water levels in the water level-power comparison table according to the change rate obtained in step S2.

[0051] Specifically, when the washing machine is working, it records the correspondence between any water level and power, replaces the corresponding power at the water level in the preset water level-power comparison table according to the recorded correspondence between the water level and the power, and then calculates the change rate of the power before and after the replacement in the water level-power comparison table under the replaced water level, and then calculates the corresponding power of the remaining water level according to the change rate before and after the power replacement, and finally replaces the correspondence between the remaining water level and the power in the water level-power comparison table according to the calculated corresponding power of the remaining water level.

[0052] Furthermore, the washing machine records the correspondence between any water level and power when working, wherein any water level is the water level most frequently used by the user or one of the most frequently used water levels, thereby improving the adjustment efficiency of the water level-power comparison table and maximally approaching the user's usage experience.

[0053] As a specific implementation of this embodiment, the washing machine continuously records the water level manually adjusted by the user each time the user washes clothes, and then selects the power operation data corresponding to the water level most frequently used by the user to adjust the water level-power comparison table of the washing machine; or, adjusts the water level-power comparison table of the washing machine according to the power operation data corresponding to one of the water levels most frequently used by the user.

[0054] The washing machine sets a target number of times. When the target water level reaches the target number of times, the multiple power operation data of the target water level are weighted averaged to adjust the water level-power comparison table.

[0055] As a specific implementation of this embodiment, the washing machine obtains the usage frequency of each water level within a certain period of time, and selects the power operation data corresponding to the water level with the highest usage frequency to adjust the water level-power comparison table of the washing machine.

[0056] It should be noted that when the washing machine continuously records the number of times the user manually adjusts the water level, it records the number of times each water level is used within a certain period of time. If the number of times any water level is used reaches the set target number of times, the power operation data corresponding to the water level is used to adjust the water level-power comparison table of the washing machine; or, the washing machine detects which water level value has reached the target number of times of use first, and then uses that water level value as the target water level.

[0057] Furthermore, the certain period of time may be every one week or half a month, which is adjusted according to the actual usage habits of the user; the target number of times is preferably 3-6 times, which is adjusted according to the actual usage habits of the user.

[0058] As a specific implementation of this embodiment, Figure 3As shown, the water levels are sorted according to the usage proportion, and at least two water levels are selected in the sorting order as the target water levels. The power data corresponding to each water level in the target water level replaces the power of the corresponding water level in the water level-power comparison table, and the power change rate at each water level is calculated respectively; the usage proportion of each water level in the target water level is calculated, and the power of the remaining water levels is adjusted based on the sum of the products of the power change rate of each water level and the corresponding water level proportion.

[0059] Furthermore, the washing machine calculates the proportion of the target water level usage times to the total water level usage times, and then adjusts the water level-power table according to the ratio of the target water level usage times to the total water level usage times. For example, when the target water level usage times accounts for eighty percent of the total water level usage times, when replacing the corresponding data of the target water level and power in the preset water level-power comparison table under the target water level in step S1, the preset water level-power comparison table is replaced according to the ratio of eighty percent of the original power data, thereby further improving the adaptability of the water level-power comparison table to the user and enhancing the user experience.

[0060] Furthermore, when the proportion of the target water level usage times to the total water level usage times is lower than a certain ratio, at least two target water levels are set, and the power operation data detected under the target water level replaces the preset water level-power comparison table under the corresponding water level, and the corresponding power of the remaining water level in the water level-power table is replaced according to the ratio of the target water level, thereby further improving the adaptability of the water level-power comparison table to user habits.

[0061] As a specific implementation of this embodiment, when the usage frequency of the target water level accounts for less than 50% of the total water level usage frequency, at least two target water levels are set to ensure that the adjusted water level-power comparison table adapts to the user's personal usage habits.

[0062] Specifically, for example: the usage times of the two target water levels account for 40% and 30% of the total water level usage times respectively. After replacing the corresponding data of the target water level and power in the preset water level-power comparison table under the target water level in step S1, the non-target water level in the water level-power comparison table is replaced according to the ratio of 40% and 3% of the two target water level power data respectively, so as to further improve the adaptability of the water level-power comparison table to the user and enhance the user experience.

[0063] The present invention discloses a method for adjusting the water level of a washing machine, which records the water level value manually adjusted by the user, adjusts a preset water level-power comparison table, forms a water level-power relationship suitable for the washing machine, and improves the washing effect of the washing machine.

[0064] Furthermore, by recording the water level values ​​manually adjusted by the user and the user's washing machine usage habits, even if the user forgets to adjust the water level value, the washing machine will form a water level-power relationship that conforms to the user's usage habits based on the previous water level adjustment data, forming a personalized customization program to meet the user's personalized usage needs and enhance the user's usage experience.

[0065] As a specific implementation of this embodiment, the water level of the washing machine is related to the weight and category of the clothes. The user manually adjusts the water level value according to the clothes to be washed, and the washing machine generates a relationship between the weight of the clothes and the water level that suits the user according to the user's habit of adjusting the water level.

[0066] Specifically, the present invention records the power operation data of the washing machine each time the washing machine works, and adjusts the water level-power comparison table of the washing machine, so that the water level-power comparison table of the washing machine corresponds to the actual condition of the washing machine. After putting in the clothes, the user manually adjusts the expected water level value according to the weight and category of the clothes put in. While recording the operating power of the washing machine, the washing machine also records the water level value manually adjusted by the user, and generates a relationship between the clothing weight and the water level that conforms to the user's habit of adjusting the water level.

[0067] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
