The following explains an application scenario of the embodiment of the present invention:
fig. 1 is an application scenario diagram of a water inflow control method according to an embodiment of the present invention, and as shown in fig. 1, an execution main body of the water inflow control method according to the embodiment of the present invention may be an intelligent washing machine, and when clothes are put into the intelligent washing machine and the intelligent washing machine is in a ready-to-wash 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 acquires the voice information of the user, the corresponding target clothes information and the water inflow information matched with the target clothes information are determined according to the voice information, and the water inflow is controlled, so that a proper amount of water is injected into the intelligent washing machine, the subsequent washing effect is improved, and meanwhile, the waste of water resources is avoided.
In the related art, the automatic water inlet control technology of the washing machine generally performs water inlet amount matching according to the weight of the laundry, and determines a water inlet amount corresponding to the weight of the laundry through a preset program. However, in the above method, because of different characteristics of different clothes, for example, real silk clothes are light in weight and generally water-absorbing; the down jacket is heavy in weight and good in water absorption, after various types of clothes are mixed, the water consumption required for washing the clothes is uncertain, the water consumption is simply evaluated through the total weight, the water inflow in the washing machine is too much or too little, the problem of inaccurate water inflow matching is caused, the washing effect of the clothes is influenced, and the waste of water resources is caused.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated 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 the embodiment of the present invention is an intelligent washing machine, as shown in fig. 2, the water inflow control method according to the embodiment includes the following steps:
step S101, acquiring user voice information.
Illustratively, the voice information of the user is a sound signal containing instruction information sent by the user, and after the sound signal is acquired by the intelligent washing machine, the instruction information in the sound 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 is set by user-defined input, and is not specifically limited herein.
For example, the intelligent washing machine is provided with a sound collection device, and the intelligent washing machine collects the sound in the environment through the sound collection device to capture the user voice information; 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 acquires the voice information from the terminal device in a wireless communication manner, where specific manner and way of acquiring the voice information of the user are not limited.
In one possible implementation manner, before acquiring the voice information of the user, the intelligent washing machine sends a prompt tone to the external environment, and after the prompt tone, collects a sound signal in the environment to acquire the voice information of the user. By the method, the interference caused by the false acquisition of invalid voice information can be reduced, and the quality of the acquired user voice information is improved.
In another possible implementation manner, before the intelligent washing machine acquires the voice information of the user, the intelligent washing machine receives a water quantity detection awakening instruction input by the user; and receiving user voice information input by a user in response to the water quantity detection awakening instruction.
Specifically, the voice input and control technology needs a relatively quiet use environment in practical use, and can remove irregular noise through a noise reduction algorithm, however, for the sound emitted by other non-operation users, the sound is the same as the voice information emitted by the operation user and has the sound characteristics of the voice information, so that the sound is difficult to distinguish, the wrong 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 sound interference caused by other external non-operation users, the intelligent washing machine receives a water quantity detection awakening instruction input by a real operation user before acquiring the voice information of the user, and then responds to the water quantity detection awakening instruction to acquire the voice signal to acquire the voice information of the user, so that the sound interference caused by other external sounds is effectively avoided.
Step S102, responding to the voice information of the user, and acquiring the target clothes information.
Illustratively, the user voice information includes specific clothing description information, including, for example: "a down coat", two pieces greasy shirt. According to the clothes description information, the target clothes information can be determined correspondingly. More specifically, the target laundry information may include information describing the type of laundry, the number of laundry, the material of laundry, the 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, the target laundry information may be implemented in various manners, such as a laundry parameter item and a corresponding laundry parameter value. More specifically, for example, the laundry parameter items include a laundry type, a laundry quantity, and a laundry material, and the laundry parameter values corresponding thereto are shirt, 2 pieces, and pure cotton, respectively. Of course, the target clothes information may also be realized in a manner of identification and numbering, which is not illustrated here.
And step S103, acquiring target water inflow information according to the target clothes information.
Due to different clothes information, different water consumption is needed when washing is performed, and therefore, the target clothes to be washed corresponding to the target clothes information need to be washed by using the water inflow matched with the target clothes information. Illustratively, a water inflow rule representing the mapping relationship between different clothes information and water inflow is preset in the intelligent washing machine. Specifically, for example, 1L of pure cotton water for shirt, 3.75L of down jacket and shirt water for shirt. According to the preset water inflow rule, the water consumption required by different clothes information can be determined, and then the corresponding water inflow can be determined.
For example, the water inflow rule may be one or more configuration tables including the corresponding relationship between different clothes information and water inflow, or may be a logic expression, by which different clothes information, such as the number of clothes, the material of the clothes, the type of the clothes, and the degree of soiling of the clothes, may be used as input values, and the corresponding water inflow may be output, so as to determine the water inflow information corresponding to the different clothes information.
And step S104, controlling the water inflow according to the target water inflow information.
Specifically, after the target water inflow information is determined, the water inflow control is carried out according to the target water inflow information, and after the water amount matched with the target water inflow information is injected, the clothes are washed, so that the water inflow detection and injection process is completed.
In the embodiment, the voice information of the user is acquired, the voice information of the user is responded, the information of the target clothes is acquired, the information of the target water inflow is acquired according to the information of the target clothes, and the water inflow control is performed according to the information of the target water inflow. The target clothes information is confirmed through the voice information of the user, so that the target water inflow information confirmed according to the target clothes information can be better matched with the target clothes information, accurate water inflow control is achieved, the washing effect of clothes is improved, and waste of water resources 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 then the water inflow control method according to this embodiment includes the following steps:
step S201, acquiring user voice information.
Step S202, analyzing the voice information of the user to obtain the keyword information.
For the user voice information input by the user, according to the language habit of the user, the user voice information generally consists of keyword information and non-keyword information, wherein the non-keyword information is generally words without actual meanings such as connecting words, adverbs, words with different meanings in spoken language expression, and the like, such as kayi, tweed, draughts, and the like; the keyword information is important information describing the clothing information, such as quantifier, noun describing the type of clothing, noun describing the material of clothing, etc. In a possible implementation manner, a keyword information base is preset in the intelligent washing machine, and the keyword information describing the clothes information in the user voice information can be obtained by analyzing the user voice information through the keyword information base. The keyword information base may be preset when the intelligent washing machine leaves a factory, may also be input and set by a user according to personal habits, may also be obtained by the intelligent washing machine in a self-learning manner, and 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 clothes parameter item correspondingly has a clothes parameter value.
After determining the keyword information in the user voice information, processing the keyword information may generate target laundry data having a specific format for describing features of the target laundry. Illustratively, the target clothes data includes a target clothes and corresponding clothes parameter items, for example, keyword information includes several keywords of "target clothes a", "3 pieces", "pure cotton" and "shirt", according to which the target clothes a can be determined, and the corresponding clothes parameter items include: the clothes type, the clothes material, the clothes quantity and the clothes parameter values corresponding to the clothes parameter items are shirt, pure cotton and 3 pieces respectively.
Step S204, determining the target clothes and the 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 the target clothes and the corresponding clothes parameter items as target clothes information for determining the characteristics of the target clothes needing to be washed in the intelligent washing machine. The matching of the water inflow is carried out according to the target clothes information, the accuracy of water inflow matching can be improved, the waste of water resources is avoided, and the washing effect is improved.
In one possible implementation, the target clothes information includes clothes type, clothes quantity and clothes material.
And S205, determining basic water consumption information corresponding to each target clothes according to the clothes type and the clothes quantity.
For clothes made of specific materials, the water consumption for washing is determined by the type and quantity of the clothes, for example, the water consumption for a coat is 2L, the water consumption for a pair of shorts is 1L, and the like. As the amount of laundry increases, the amount of water used increases. Of course, it is understood that, from the dimension of the quantity of clothes to the water consumption, when the quantity of clothes is increased, the water consumption is increased linearly or not, and the mapping relationship between the quantity of clothes and the water consumption can be determined according to specific use scenes and equipment characteristics, and is not limited in detail herein. In one possible embodiment, as the number of the laundry increases, the water amount is linearly accumulated within a specific capacity range of the intelligent washing machine.
Step S206, according to the clothes material, the water absorption information corresponding to each target clothes is determined.
Different clothes materials have different water absorption, for example, clothes made of pure cotton has better water absorption, and clothes made of polyester fiber has poorer water absorption. The water absorption information corresponding to each target clothes can be determined according to the clothes material, and the larger the water absorption of the target clothes is, the more water is needed by the target clothes during washing.
Optionally, as shown in fig. 4, step S206 includes two specific implementation steps S2061 and S2062:
step S2061, obtaining preset clothes water absorption information, where the clothes water absorption information is used to represent water absorption characteristics of different clothes.
The garment water absorption information may represent water absorption characteristics of different garments, and may be, for example, a configuration table representing water absorption of different garment materials, including different garment materials and unit mass water absorption corresponding thereto, for example, a gram of water absorbed per 100 grams of pure cotton material; the flax material absorbs B grams of water per 100 grams.
Step S2061 is to obtain the water absorption amount information required for each target laundry based on the laundry water absorption amount information.
For example, the target clothes information of the target clothes further includes clothes type information, such as shirt, coat, and down jacket. Based on the clothes type information, the mass of the target clothes can be roughly judged, and further based on the clothes water absorption information and the mass of the target clothes, the water absorption amount information required by the target clothes can be determined.
In one possible implementation, the target laundry information further includes laundry insult information.
And step S207, determining water temperature information corresponding to each target clothes according to the clothes fouling information.
Illustratively, the laundry stain information includes oil stain, blood stain, and the like. When different stains are stained on the target clothes, the water temperature can be correspondingly adjusted in order to achieve a better cleaning effect. For example, for clothes stained with oil stains, in order to better clean the oil stains, higher water temperature should be used for washing.
For example, the intelligent washing machine is preset with water temperature adjusting information, the water temperature adjusting information is used for representing the mapping relation between the water temperature and the clothes stain 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 adjusting information, water temperature information corresponding to the clothes damage information can be determined. For example, if the laundry damage information includes oil stain, the corresponding water temperature information may be determined to be 50 degrees celsius according to the water temperature adjustment information.
And step S208, acquiring preset water temperature change information.
For example, the water temperature change information is used to represent a mapping relationship between water temperature and amount of water used by the laundry, and/or between water temperature and amount of water absorbed by the laundry. The water temperature change information may be configuration information preset in the intelligent washing machine to represent a change relationship between the water consumption of washing the laundry or the water absorption amount of the laundry when the water temperature changes.
And step S209, calibrating the basic water consumption and/or the water absorption information according to the water temperature change information and the water temperature information.
And 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 in washing the laundry is changed, 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 a possible implementation mode, the water temperature change information is a mapping table of the change relation between the user characterization water temperature and the water consumption, the corresponding optimized water consumption is determined according to the water temperature change information and the water temperature information, the basic water consumption is calibrated according to the optimized water consumption, the process of further optimizing the water inflow detection is realized, more accurate water inflow control is realized, and the purposes of saving water resources and improving the washing effect are achieved.
Similarly, in another possible implementation, the water suction amount is calibrated according to the water temperature information and the water temperature change information, so that the process of optimizing the water inflow detection can be realized, more accurate water inflow control is realized, the purposes of saving water resources and improving the washing effect are achieved, and the description is omitted here.
