The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example one
As shown in fig. 1, the present embodiment provides a control method of a washing machine, which judges the weight of laundry having been put into a washing tub assembly 2 according to a sinking displacement of the washing tub assembly 2 and prompts a user whether the laundry can be added into the washing tub assembly 2.
In the scheme, the washing machine can be a drum washing machine, a pulsator washing machine or a washing machine with a drying function. The washing machine has a cabinet 1, and a displacement detecting device 3 is provided in the cabinet 1 for detecting a sinking displacement of a washing tub assembly 2. After the laundry is loaded into the washing drum, the washing drum assembly 2 sinks due to gravity, and the degree of sinking represents the weight of the loaded laundry. The control device of the washing machine can therefore analyze and judge the weight of the laundry that has been put into the washing drum in real time by detecting the sinking displacement of the washing drum assembly 2 in real time, and prompt the user whether the laundry can be added into the washing drum again, so as to avoid the occurrence of the situation that too many laundry are put into the washing drum, or the washing drum needs to be replaced.
In order to facilitate the analysis of the relationship between the washing drum sinking displacement and the laundry weight, the empty drum height and the full drum height of the washing drum assembly 2 are taken as reference, respectively. The sinking displacement of the washing drum assembly 2 is set to a minimum value M when the washing drum assembly 2 is empty and to a maximum value N when the washing drum assembly 2 is full. When the user adds laundry to the washing drum, specific situations include, but are not limited to, the following:
in case 1, the washing tub assembly 2 is gradually moved downward as the laundry is added by the user, and when the washing machine judges that the sinking displacement of the washing tub assembly 2 is equal to or greater than the maximum value N, the user is prompted to stop adding the laundry.
According to the scheme, the washing drum is used as the weighing device, when the user puts clothes in, the weight is detected and prompted in real time, if the maximum limit value is reached, the user is prompted to be incapable of increasing the clothes to enter, the phenomenon that the user repeatedly takes the clothes to replace the washing drum can be avoided, the washing efficiency and the washing effect can be improved, the intellectualization of the washing machine is improved, and the user experience is improved.
And 2, when the washing machine judges that the sinking displacement of the washing drum assembly 2 is greater than or equal to the minimum value M and less than the maximum value N in the process of adding the clothes, prompting the user that the clothes can be continuously added.
When the washing machine judges that the sinking displacement of the washing drum assembly 2 is between the no-load minimum value and the full-load maximum value, the washing machine shows that less clothes are added into the washing drum, the residual space in the washing drum is larger, and more clothes can be loaded, so that a user is prompted to continue to add clothes into the washing drum, and therefore the washing machine can facilitate the user to act and avoid invalid repeated actions.
In this case, further, in order to obtain a better washing effect, when the washing machine determines that the sinking displacement of the washing drum assembly is greater than the minimum value M and less than the maximum value N, the user is prompted whether to add the clothes to the washing drum assembly according to the information of the degree of contamination of the added clothes, and/or the information of the material of the clothes, and/or the information of the color.
According to the specific scheme, the washing machine obtains a corresponding washing program according to the dirt degree information, the clothes material information and/or the color information of the added clothes, and prompts a user to stop adding the clothes if the sinking displacement of the washing drum assembly is judged to reach the maximum value A corresponding to the washing program; if the sinking displacement of the washing drum assembly is judged to be smaller than the value A, prompting the user that the clothes can be added.
The value A is the maximum value A in the optimal weight range corresponding to the washing program obtained by the washing machine according to the dirt degree information, the clothes material information and the color information of the added clothes. The value of A is smaller than the value of N and larger than the value of M.
The washing conditions of full load and small amount of clothes are not necessarily the best cleaning degree, so that the clothes multiple information can be combined and analyzed to give the best washing scheme to the user. In the scheme, on the basis of analyzing the weight of the added clothes, the optimal washing program and the optimal weight are obtained by further combining the information of the material, the dirt degree and the like of the clothes, when the added clothes reach the appropriate weight, the clothes are prompted to stop being added, and if the added clothes do not reach the appropriate weight, the clothes are prompted to be added.
For example, when the washing machine detects that two dirty clothes are put into the washing drum and the color is darker, a proper washing program and washing weight are recommended, and whether the addition needs to be continued or not is judged by combining the detected weight of the clothes, and the user is prompted; or the weight of the detected clothes with cotton and linen or strong water absorbability is light and does not exceed the maximum carrying capacity N, whether the clothes are added or not can be analyzed according to the detected information, and the phenomenon that the clothes with too large water absorbability are few and serious eccentricity is caused is avoided.
As a specific case, when the laundry is dirty or the laundry is made of cotton, the washing machine analyzes and judges that the weight of the laundry which can achieve a better washing effect is a according to the laundry information, for example, a may be two thirds of the value of N, and when the washing machine judges that the weight of the laundry put into the washing drum assembly has not reached N but has reached a according to the sinking displacement of the washing drum assembly, the user is prompted to stop adding the laundry, so that the best washing effect can be ensured.
And 3, in order to further facilitate the user to know the specific clothes adding situation, in the clothes adding process of the user, the washing machine analyzes and obtains the weight of the added clothes according to the sinking displacement data of the washing drum assembly 2 acquired in real time, and prompts the user to keep the weight of the remained and added clothes.
In the scheme, the washing machine not only prompts the user to add clothes into the washing drum continuously, but also displays the weight of the clothes which can be added specifically, for example, prompts the user to add 2kg of clothes into the washing drum continuously. Therefore, the user can timely know the weight information of the clothes added into the washing machine, can clearly know the weight of the clothes to be added, is convenient for the user to add the clothes with proper weight, avoids the situation that the clothes need to be taken out after being added, and can improve the washing effect by washing the clothes with proper weight.
Further, after analyzing and judging the weight of the clothes added into the washing drum and the weight of the residual addable clothes, the washing machine further compares the weight data of the residual addable clothes with the stored data for analysis, and directly prompts the user of the number of the residual addable clothes.
In this scheme, washing machine real-time detection washing barrel assembly 2 sink the displacement back, and the direct suggestion user can continue the number of pieces of the clothing that adds, so more directly perceived, convenience of customers uses. The weight of the clothes is different due to the different sizes and thicknesses of the clothes. Therefore, the washing machine needs to calculate the number-of-pieces information of the laundry that can be added according to the pre-stored laundry weight data classified according to different criteria. For example, the pre-stored data may include weight averages of laundry classified by different seasons, weight averages of laundry classified by different materials, weight averages of laundry classified by size and style, and the like.
As a specific embodiment, the manner in which the washing machine prompts the user of the number of pieces of laundry that may be added includes: after the washing machine obtains the weight of the residual addable clothes, the weight data refers to the average weight values of the large clothes, the middle clothes and the small clothes which are stored in advance, the number of the addable large clothes, the number of the middle clothes and the number of the small clothes are respectively calculated, and the addable large clothes, the number of the middle clothes and the number of the small clothes are respectively prompted to a user. Thus, the user can know at a glance which size of clothes should be added continuously, and the washing effect is improved.
In the scheme, the modes of prompting the user by the washing machine can be various, and the prompting device can be an existing visual or auditory or gustatory prompting device or an improved prompting device. The visual prompting device can adopt display screen display, projection display, flashing lamps or prompting lamps with different colors and the like; the auditory prompting device adopts voice broadcast, prompting sound alarm and the like, and the gustatory prompting device comprises devices emitting different smells according to different conditions and the like.
As a specific embodiment, the manner of prompting the user by the washing machine includes: voice broadcasting is carried out for prompting, and/or display is carried out on a display screen, and/or an indicator lamp is used for displaying;
the washing machine can directly perform voice broadcast after monitoring the sinking displacement of the washing drum assembly 2 in real time, prompt the user of the weight or the number of pieces of clothes which can be added, and prompt the user to stop adding when the maximum value is reached. Or the numbers, and/or characters, and/or patterns are displayed on the display screen to the user, the user is prompted to add the weight or the number of pieces of clothes, and the user is prompted to stop adding the clothes when the maximum value is reached. Or indicate the user with a different colored, flashing indicator light. Or, a plurality of prompting modes are combined for use, so that a better prompting purpose is achieved.
Example two
As shown in fig. 2, the present embodiment is a further limitation of the first embodiment, the washing machine in the present embodiment includes at least two washing drum assemblies 2, and when the washing machine determines that the sinking displacement of the washing drum assembly 2 to which the laundry is being added reaches the maximum value N, the user is prompted to stop adding the laundry, or the user is prompted to add the laundry to the other washing drum assemblies 2.
