The following explains the application scenario of the embodiment of the present invention:
fig. 1 is an application scenario diagram of a water inflow control method provided by an embodiment of the present invention, where as shown in fig. 1, an execution main body of the water inflow control method provided by the embodiment of the present invention may be an intelligent washing machine, and when clothes are put into the intelligent washing machine and are in a washing ready state, the intelligent washing machine sends a prompt tone to a user, and the user performs voice input according to the prompt tone. After the intelligent washing machine obtains the voice information of the user, corresponding target clothes information and water inflow information matched with the target clothes information are determined according to the voice information, and water inflow control of the running water is carried out, so that a proper amount of water is injected into the intelligent washing machine, the subsequent washing effect is improved, and meanwhile waste of water resources is avoided.
In the related art, the technology of automatic water inflow control of a washing machine generally performs water inflow matching according to the weight of laundry, and determines a water inflow corresponding to the weight of laundry through a preset program. However, in the above method, since different clothes have different characteristics, for example, real silk clothes are light in weight and generally have water absorption; the down jacket has heavy quality and good water absorbability, after various different types of clothes are mixed, the water consumption required for washing the clothes is uncertain, and the water consumption is simply estimated by total weight, so that the problem of inaccurate water inflow matching in the washing machine is caused, the clothes washing effect is further affected, and the water resource is wasted.
The following describes the technical scheme of the present invention and how the technical scheme of the present invention solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a water inflow control method according to an embodiment of the present invention, and an execution main body of the water inflow control method according to an embodiment of the present invention is an intelligent washing machine, as shown in fig. 2, and the water inflow control method according to the embodiment of the present invention includes the following steps:
step S101, user voice information is acquired.
The user voice information is an audio signal containing instruction information sent by a user, and after the intelligent washing machine obtains the audio signal, the instruction information in the audio signal can be analyzed and determined through a voice recognition technology. Specifically, the method for analyzing the instruction information in the sound signal is preset in the intelligent washing machine or set by user-defined input, which is not specifically limited herein.
Various methods for acquiring the voice information of the user exist, for example, a sound acquisition device is arranged on the intelligent washing machine, and the intelligent washing machine acquires the sound in the environment through the sound acquisition device to capture the voice information of the user; for another example, the intelligent washing machine is in communication connection with other terminal devices, such as a smart phone, the user inputs voice information through the terminal device, and the intelligent washing machine obtains the voice information from the terminal device through a wireless communication mode, and here, a specific mode and a specific way for obtaining the voice information of the user are not limited.
In one possible implementation, the intelligent washing machine sends a prompt tone to the external environment before acquiring the user voice information, and collects the sound signal in the environment after the prompt tone to acquire the user voice information. By the method, interference caused by false acquisition of invalid voice information can be reduced, and quality of acquired user voice information is improved.
In another possible implementation manner, the intelligent washing machine receives a water quantity detection wake-up instruction input by a user before acquiring voice information of the user; and responding to the water quantity detection awakening instruction, and receiving user voice information input by a user.
Specifically, the voice input and control technology requires a quieter use environment in actual use, and irregular noise can be removed through a noise reduction algorithm, however, for the voice emitted by other non-operation users, as the voice information emitted by the operation users is the same, the voice input and control technology has the voice characteristics of the voice information, so that the voice information is difficult to distinguish, the false acquisition of the voice information is caused, and the subsequent target clothes judgment and water quantity judgment process is influenced. Therefore, in order to prevent the sound interference caused by other external non-operation users, the intelligent washing machine receives the real water quantity detection awakening instruction input by the operation user before acquiring the user voice information, then responds to the water quantity detection awakening instruction to acquire the sound signal, acquire the user voice information and effectively avoid the sound interference caused by other external sounds.
Step S102, responding to the voice information of the user, and acquiring target clothes information.
Illustratively, the user voice information includes specific clothing description information, including, for example: one down jacket and two shirts with greasy dirt. According to the clothes description information, target clothes information can be correspondingly determined. More specifically, the target laundry information may include information describing contents of laundry type, laundry amount, laundry material, stain condition, and the like. After responding to the user voice information, the user voice information is identified and analyzed, and target clothes information for describing clothes conditions can be obtained.
For example, there may be a plurality of implementations of the target laundry information, for example, laundry parameter items and corresponding laundry parameter values. More specifically, for example, the laundry parameter items include laundry type, laundry number, laundry material, and laundry parameter values corresponding thereto are shirt, 2 pieces, and pure cotton, respectively. Of course, the target clothes information may be realized by means of identification and numbering, and is not exemplified here.
Step S103, acquiring target water inflow information according to the target clothes information.
Because different clothes information needs different water consumption when washing, the target clothes to be washed corresponding to the target clothes information needs to be washed by using the water inflow matched with the target clothes information. Illustratively, a water inflow rule representing a mapping relationship between different laundry information and water inflow is preset in the intelligent washing machine. Specifically, for example, a piece of pure cotton shirt uses 1L of water, a piece of down jackets and a piece of shirt uses 3.75L of water. According to the preset water inflow rule, the water consumption required by different pieces of clothes information can be determined, and then the corresponding water inflow can be determined.
The water inflow rule may be one or more configuration tables, including correspondence between different pieces of laundry information and water inflow, or may be a logic expression, through which different pieces of laundry information, such as the number of laundry, the material quality of laundry, the type of laundry, and the degree of laundry contamination, may be used as input values, and corresponding water inflow is output, so as to determine the water inflow information corresponding to the different pieces of laundry information.
Step S104, controlling the water inflow according to the target water inflow information.
Specifically, after the target water inflow information is determined, water inflow control is performed according to the target water inflow information, and after water amount matched with the target water inflow information is injected, washing is performed on clothes, so that the water inflow detection and injection processes are completed.
In this embodiment, by acquiring the user voice information, the target laundry information is acquired in response to the user voice information, the target water inflow information is acquired according to the target laundry information, and the water inflow control is performed according to the target water inflow information. Because the target clothes information is confirmed through the user voice information, the target water inflow information confirmed according to the target clothes information can be better matched with the target clothes information, so that accurate water inflow control is realized, the clothes washing effect is improved, and the water resource waste is reduced.
Fig. 3 is a flowchart of a water inflow control method according to another embodiment of the present invention, and as shown in fig. 3, the water inflow control method according to this embodiment further refines steps S102 to S103 on the basis of the water inflow control method according to the embodiment shown in fig. 2, and the water inflow control method according to this embodiment includes the following steps:
step S201, user voice information is acquired.
Step S202, analyzing the voice information of the user to obtain keyword information.
The user voice information input by the user is usually composed of keyword information and non-keyword information according to the language habit of the user, wherein the non-keyword information is generally words with no practical meaning such as connecting words, adverbs, intonation words and the like in spoken language expression, for example, words such as 'one's name ',' another 'one's name and the like; the keyword information is important information describing the clothes information, such as a graduated word, a noun describing the type of clothes, a noun describing the material of clothes, etc. In one possible implementation manner, a keyword information base is preset in the intelligent washing machine, and the user voice information is analyzed through the keyword information base, so that the keyword information of describing the clothes information by the user in the user voice information can be obtained. The keyword information library may be preset when the intelligent washing machine leaves the factory, may be input by a user according to personal habits, or may be obtained by the intelligent washing machine through a self-learning mode, and the implementation mode is not limited herein.
Step S203, determining target clothes and clothes parameter items corresponding to the target clothes according to the keyword information; wherein the clothing parameter item corresponds to a clothing parameter value.
After determining the keyword information in the user voice information, the keyword information is processed, and target laundry data having a specific format for describing characteristics of the target laundry may be generated. The target clothes data includes target clothes and corresponding clothes parameter items, for example, keywords including "target clothes a", "3 pieces", "pure cotton" and "shirt" in the keyword information, according to which the target clothes a can be determined, and the corresponding clothes parameter items include: the clothes type, the clothes material and the clothes quantity are respectively shirt, pure cotton and 3 clothes parameter values corresponding to the clothes parameter items.
Step S204, determining the target clothes and clothes parameter items corresponding to the target clothes as target clothes information.
For example, the keyword information parsed from the user voice information may include the target laundry B, the target laundry C, and the like in addition to the target laundry a. And taking all target clothes and corresponding clothes parameter items as target clothes information, and determining the characteristics of the target clothes which need to be washed in the intelligent washing machine. The water inflow amount is matched according to the target clothes information, so that the accuracy of water inflow amount matching can be improved, the waste of water resources is avoided, and the washing effect is improved.
Wherein in one possible implementation, the target laundry information includes a laundry type, a laundry number, a laundry material.
Step S205, according to the clothes types and the clothes quantity, basic water consumption information corresponding to each target clothes is determined.
The water consumption for washing clothes of a specific material is determined by the type and the number of the clothes, for example, the water consumption of one coat is 2L, the water consumption of one shorts is 1L, and the like. And as the amount of laundry increases, the amount of water used increases. It will be understood, of course, that as the amount of laundry increases in the dimension of the amount of water, the increase in the amount of water may or may not be linear, and the mapping relationship between the amount of laundry and the amount of water may be determined according to the specific usage scenario and the device characteristics, and is not particularly limited herein. In one possible embodiment, the water consumption is linearly accumulated in a specific capacity range of the intelligent washing machine as the amount of laundry increases.
Step S206, according to the clothing material, determining the water absorption information corresponding to each target clothing.
Different clothes are made of different materials, and have different water absorbances, for example, clothes made of pure cotton are good in water absorbability, and clothes made of polyester fiber are poor in water absorbability. According to the material of the clothes, the water absorption information corresponding to each target clothes can be determined, and the more the water absorption of the target clothes is, the more the water absorption of the target clothes is needed when the target clothes are washed.
Optionally, as shown in fig. 4, step S206 includes two specific implementation steps of steps S2061, S2062:
step S2061, acquiring preset clothes water absorption information, wherein the clothes water absorption information is used for representing water absorption characteristics of different clothes.
The water absorption rate information of the clothes can represent the water absorption characteristics of different clothes, and by way of example, the water absorption rate information of the clothes can be a configuration table representing the water absorption rate of different clothes materials, wherein the configuration table comprises the water absorption rate of the different clothes materials and the unit mass corresponding to the water absorption rate, for example, the water absorption rate A g of pure cotton materials is equal to 100 g; the flax material absorbs water B g per 100 g.
Step S2061, acquiring the water absorption information required by each target garment according to the garment water absorption information.
The target laundry information of the target laundry also includes, for example, laundry type information such as shirts, jackets, down jackets. The target clothes quality can be roughly judged according to the clothes type information, and further, the water absorption amount information required by the target clothes can be determined according to the clothes water absorption amount information and the target clothes quality.
In one possible implementation, the target laundry information further includes laundry offset information.
Step S207, determining water temperature information corresponding to each target clothes according to the clothes contamination information.
Illustratively, the garment insult information includes oil stains, blood stains, and the like. When different stains are stained on target clothes, the water temperature can be correspondingly adjusted in order to achieve a better cleaning effect. For example, for oil-stained clothing, a higher water temperature should be used for washing in order to clean oil stains better.
The intelligent washing machine is provided with water temperature adjusting information in advance, the water temperature adjusting information is used for representing the mapping relation between water temperature and clothes contamination information, and clothes with different stains can be washed corresponding to different water temperatures according to the water temperature information. Further, according to the water temperature adjustment information, water temperature information corresponding to the laundry contamination information may be determined. For example, the laundry contamination information includes oil stains, and the corresponding water temperature information may be determined to be 50 degrees celsius according to the water temperature adjustment information.
Step S208, acquiring preset water temperature change information.
Illustratively, the water temperature change information is used to characterize a mapping relationship between water temperature and laundry water consumption, and/or water temperature and laundry water absorption. The water temperature change information may be configuration information preset in the intelligent washing machine for representing a change relationship between the water consumption of washing laundry or the water absorption of the laundry when the water temperature is changed.
Step S209, the basic water consumption and/or the water absorption information are calibrated according to the water temperature change information and the water temperature information.
Step S210, determining target water inflow information according to the basic water consumption information, the water absorption information and the water temperature information.
Specifically, when the water temperature is different, the enzyme activity in the detergent used when washing laundry may vary, resulting in a change in the energy efficiency of the detergent and thus in a change in the amount of water required for washing. Therefore, when the water temperature is changed, the basic water consumption for washing the laundry is also changed. In one possible implementation manner, the water temperature change information is a mapping table of a change relation between water temperature and water consumption represented by a user, the corresponding optimized water consumption is determined according to the water temperature change information and the water temperature information, and the basic water consumption is calibrated according to the optimized water consumption, so that the water intake detection process is further optimized, more accurate water intake control is realized, and the purposes of saving water resources and improving washing effect are achieved.
Similarly, in another possible implementation manner, the water absorption is calibrated according to the water temperature information and the water temperature change information, so that the water intake detection process can be optimized, more accurate water intake control is realized, the purposes of saving water resources and improving the washing effect are achieved, and the description is omitted here.
The implementation manner and the technical effect of step S201 are the same as those of step S101 in the embodiment shown in fig. 2, and are not described herein again.
