Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present application is described in conjunction with a washing machine, the technical solution of the present invention is not limited thereto, and the water injection control method can be obviously applied to other washing apparatuses such as a washing and drying machine, without departing from the principle and scope of the present invention.
It should be noted that the terms "first" and "second" in the description of the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Based on the technical problems provided in the background art, the invention provides a water injection control method for a washing machine, which aims to determine the water absorption speed of an object to be cleaned through the water level frequency variation and adjust the water injection program of the washing machine according to the water absorption speed, so that the most reasonable water injection program is provided for the washing machine, the water injection accuracy of the washing machine is improved, the waste of water resources is avoided, and the use experience of a user is improved.
Referring to fig. 1 and 2, fig. 1 is a flow chart of a water injection control method of the present invention; FIG. 2 is a flow chart of a water injection control method according to an embodiment of the present invention. As shown in fig. 1, the water injection control method of the present invention includes the following steps:
s1, acquiring the water level frequency variation of the washing machine under the condition that the washing machine is in a water filling stage;
s2, determining the water absorption speed of the object to be cleaned according to the water level frequency variation;
and S3, adjusting the water filling program of the washing machine according to the water absorption speed.
In a preferred embodiment, the step of "acquiring the water level frequency variation of the washing machine" in the step S1 includes:
s11, acquiring a water level frequency value every preset time threshold;
and S12, determining the water level frequency variation quantity through the adjacent two water level frequency values.
Preferably, the water level frequency variation is the water level frequency value acquired N-th time to the water level frequency value acquired N +1 th time, where N is a positive integer.
In the above process, by setting the preset time threshold, a conclusion can be given whether the water level frequency value is obtained again. Through repeated tests, observation, analysis and comparison of the inventor, the scheme of determining when the preset time threshold value is the shortest time for accurately detecting the water level frequency variation and obtaining the water level frequency value again is optimal. In practical application, the actual value of the preset time threshold is not limited to the shortest time that can accurately detect the water level frequency variation, and can be obtained by a person skilled in the art according to experiments or experience.
In a preferred embodiment, the step of "determining the water absorption speed of the object to be cleaned according to the water level frequency variation" in the step S2 specifically includes:
s21, judging whether the water level frequency variation is smaller than a preset frequency variation threshold value;
s22, if the water level frequency variation is smaller than a preset frequency variation threshold, judging that the object to be cleaned absorbs water at a first speed;
and S23, if the water level frequency variation is larger than or equal to the preset frequency variation threshold, determining that the to-be-cleaned object absorbs water at the second speed.
Wherein the first speed is greater than the second speed.
Preferably, in step S22, if the water level frequency variation is smaller than the preset frequency variation threshold, it may be considered that the water absorption amount of the object to be cleaned is large or the object to be cleaned absorbs water at a constant speed within the preset time threshold, so that water molecules enter the inside of the object to be cleaned, and the water level in the inner barrel is lowered, so that the water level frequency variation is smaller than the preset frequency variation threshold, it may be determined that the object to be cleaned absorbs water at the first speed, and the fast water absorption of the object to be cleaned at the first speed means that the object to be cleaned can absorb water sufficiently within the preset time threshold.
Further, in step S23, if the water level frequency variation is less than or equal to the preset frequency variation threshold, the water absorption amount of the object to be cleaned within the preset time threshold is considered to be small or not, the water level frequency variation amount is greater than or equal to a preset frequency variation threshold due to the rise of the water level caused by the injected washing water, then the object to be cleaned can be judged to absorb water slowly according to the second speed (the object to be cleaned absorbing water slowly according to the second speed means that the object to be cleaned can not absorb water fully within the preset time threshold), so that the water absorption speed of the object to be cleaned can be accurately judged according to the water level frequency variation, and then can adjust washing machine's water injection procedure according to the speed of absorbing water of waiting to wash the thing, provide the most reasonable water injection procedure for washing machine, improve washing machine water injection accuracy, avoid the waste of water resource, and then improved user's use and experienced.
In the process, the conclusion of judging the water absorption speed of the object to be cleaned can be given through setting the preset frequency change threshold value. Through repeated tests, observation, analysis and comparison of the inventor, the preset frequency change threshold is determined to be the minimum frequency change amount capable of accurately judging the water absorption speed of the object to be cleaned, and the judgment scheme of the water absorption speed of the object to be cleaned is optimal. In practical application, the actual value of the preset frequency change threshold is not limited to the minimum frequency change amount which can accurately judge the water absorption speed of the object to be cleaned, and can be obtained by a person skilled in the art according to experiments or experience.

and S31, making the washing machine continuously perform the water filling operation.
Particularly, under the condition that the object to be cleaned is judged to absorb water rapidly according to the first speed, the object to be cleaned can absorb water rapidly, the water level of the washing water is influenced in time, the phenomenon that too much washing water is injected due to the fact that the object to be cleaned does not absorb water timely is avoided, and the washing machine continues to execute water injection operation until the water is injected to the second preset water level threshold value.
The second preset water level threshold is the water level determined according to the weight of the objects to be washed or the water level corresponding to the selected washing program.
In a preferred embodiment, when it is determined that the object to be washed slowly absorbs water at the second speed, the step of "adjusting the water filling program of the washing machine according to the water absorption speed" in the step S3 includes:
s32, making the washing machine execute auxiliary water absorption operation;
s33, after the washing machine performs the auxiliary water suction operation, the washing machine continues to perform the water filling operation.
Specifically, under the condition that the object to be washed is judged to slowly absorb water at the second speed, the water absorption amount of the object to be washed in the preset time threshold is small or the object to be washed does not absorb water, the object to be washed does not absorb water sufficiently, and the accurate influence on the water level of the washing water cannot be generated.
Preferably, the washing machine includes an inner tub, and the step of "making the washing machine perform the auxiliary water absorption operation" in the step S32 includes:
s321, stopping water injection of the washing machine;
and S322, intermittently rotating the inner barrel according to the first rotation time.
Preferably, in step S321, the washing machine stops filling water, so as to avoid continuing filling water into the inner tub under the condition that the object to be cleaned does not absorb water sufficiently, avoid excessive filling water caused by insufficient absorption of water, improve the accuracy of filling water into the washing machine, and avoid waste of water resources.
Further, in step S322, the inner barrel is intermittently rotated according to the first rotation time, so as to drive the washing water in the inner barrel to rotate, so that the objects to be washed in the inner barrel can be distributed more uniformly under the action of the flowing water flow, the objects to be washed can fully absorb water, and the water level of the washing water is accurately influenced.
It is further understood that the inner tub may be continuously rotated for a first rotation time without departing from the spirit and scope of the present invention.
In a preferred embodiment, in the process of "making the washing machine continue to perform the water filling operation" in the above steps S31 and S33, the water filling control method further includes:
s34, acquiring the current water level of the washing machine;
s35, judging whether the current water level is larger than or equal to a first preset water level threshold value or not;
s36, if the current water level is less than the first preset water level threshold, the washing machine continues to execute water filling operation;
s37, if the current water level is more than or equal to the first preset water level threshold, the washing machine executes the auxiliary water absorption operation again;
s38, after the washing machine performs the supplementary water suction operation again, the washing machine performs the water filling operation again.
Preferably, the first preset water level threshold is smaller than the second preset water level threshold.
Further, the first preset water level threshold is two gears smaller than the second preset water level threshold, for example, if the second preset water level threshold is 7 gears, the first preset water level threshold is 5 gears.
Of course, the water injection control method may further include the steps S34 to S38 after the above-described steps S31 and S33 without departing from the principle and scope of the present invention.
Preferably, the step of "acquiring the current water level of the washing machine" in the step S34 specifically includes:
s341, acquiring a current water level frequency value of the washing machine;
and S342, determining the current water level according to the current water level frequency value.
Preferably, in step S342, since the water level frequency value is negatively correlated with the current water level, the water level frequency value decreases as the inlet water level increases, and after the water level frequency value is determined, the inlet water level negatively correlated therewith is also determined, so that the current water level can be determined according to the current water level frequency value.
Preferably, in step S36, if the current water level is lower than the first preset water level threshold, which indicates that the water level in the inner tub is low, and the water level will not exceed the second preset water level threshold after the laundry absorbs water sufficiently, the washing machine will continue to perform the water filling operation.
Preferably, the step of "causing the washing machine to perform the auxiliary water absorption operation again" in the step S37 specifically includes:
s371, stopping water injection of the washing machine;
and S372, intermittently rotating the inner barrel according to the second rotation time.
Preferably, in step S371, if the current water level is greater than or equal to the first preset water level threshold, it indicates that the water level in the inner tub is high, after the object to be cleaned absorbs water sufficiently, the water level may exceed the second preset water level threshold, and in order to avoid the water level exceeding the second preset water level threshold, the washing machine stops injecting water, so that water is prevented from being continuously injected into the inner tub under the condition that the object to be cleaned does not absorb water sufficiently, excessive washing water is prevented from being injected due to insufficient absorption of the object to be cleaned, the accuracy of water injection of the washing machine is improved, and waste of water resources is avoided.
Further, in step S372, the inner barrel is intermittently rotated according to the second rotation time, so that the washing water in the inner barrel is driven to rotate, the objects to be washed in the inner barrel can be distributed more uniformly under the action of the flowing water, the objects to be washed can fully absorb water, and the water level of the washing water is accurately influenced.
It is further understood that the inner tub may be continuously rotated for the second rotation time without departing from the spirit and scope of the present invention. In practical applications, the second rotation time and the first rotation time, for example, 10S for the first rotation time and 15S for the second rotation time, can be flexibly adjusted and set by those skilled in the art without departing from the principle and scope of the present invention.
Preferably, the step of "causing the washing machine to perform the water filling operation again after the washing machine performs the supplementary water suction operation again" in the step S38 specifically includes:
and S381, enabling the washing machine to fill water to a second preset water level threshold value.
Specifically, after step S372, the object to be cleaned has absorbed water sufficiently, so that the water level is further raised, and the water is continuously injected into the inner tub without injecting too much washing water due to insufficient absorption of water by the object to be cleaned, so that the washing machine directly injects water to the second preset water level threshold, thereby meeting the water level requirement of the user for cleaning the object to be cleaned.
