Description
Technical Field
The invention relates to the field of clothes washing and protecting technology and intelligent washing research thereof, in particular to a method and a system for visualizing a clothes washing and protecting process and dynamically feeding back and regulating washing and protecting parameters of each stage.
Background
The essence of the research on the clothes washing and protecting technology is to research and develop how to utilize a washing device (washing machine) to quickly and efficiently separate dirt stained on clothes from the clothes, so the technology can also be called the technology of washing and protecting clothes by the washing device (washing machine). The process of separating stains from clothes by water flow, detergent, mechanical force and the like in the washing equipment (washing machine) is a common life phenomenon, but the understanding of the clothes is not thorough so far and the clothes are still at the level of knowing the stains and the stains.
The reasons for the above phenomena are:
firstly, the laundry equipment (washing machine) on the market at present does not have the functions of dynamically feeding back and regulating and controlling the corresponding washing and protecting parameters according to the field operation condition and the quality improvement and efficiency improvement washing and protecting requirement according to the real-time dynamic tracking (visualization) of the washing and protecting parameters (water injection time, water injection quantity, water temperature, soaking time, main washing rotating speed, main washing rotating direction, water injection quantity, water temperature, soaking time, main washing rotating speed, main washing rotating direction, water injection quantity, water temperature, soaking time, main washing rotating speed, main washing rotating direction, water removal time, water removal speed and water removal rotating direction) of the washing and the moving state of the clothes (washing machine) Can be used. If the visualization of the washing and protecting parameters and the motion forms of each washing and protecting stage in the washing and protecting process of the washing machine is to be realized, not only various high-precision sensors need to be additionally arranged on the equipment, but also various reconstruction (punching and wiring) or replacement of hardware components of the equipment is needed, and meanwhile, the compiling and function debugging of corresponding software are needed to be carried out by comprehensively considering the requirements of all the parties, so that the operation is quite complicated, and the visualization of the washing and protecting parameters and the motion forms of each washing and protecting stage in the washing and protecting process of the washing machine can be realized by no research device at;
secondly, all washing program parameters (water filling time, water filling quantity, water temperature, soaking time, main washing times, main washing time, main washing rotating speed, main washing rotating direction, rinsing times, rinsing time, rinsing rotating speed, rinsing rotating direction, dewatering times, dewatering time, dewatering rotating speed and dewatering rotating direction) of the washing equipment (washing machine) on the market are fixed, the adjustment levels of all parameters or the combination form (washing program) are limited, and the clothes dryer products of all brands are not greatly different. In short, no matter what the current research devices or the washing machine devices on the market can not realize the visualization of the washing process (washing parameters and clothes motion forms) and the free regulation and control of the washing parameters ((water injection time, water injection quantity, water temperature, soaking time, main washing times, main washing time, main washing rotating speed, main washing rotating direction, rinsing times, rinsing time, rinsing rotating speed, rinsing rotating direction, dewatering times, dewatering time, dewatering rotating speed and dewatering rotating direction).
The problems of clothes performance reduction, water consumption, energy consumption, time consumption, low cleaning rate and the like after washing of washing equipment (washing machine) are always the focus of attention, but the current research is only limited to experimental research on optimization of washing parameters of the washing machine and construction of an empirical mathematical model, the attention to washing parameters and clothes motion tracks in each stage of the washing process of the washing machine is relatively less, and the adsorption and desorption rules and the motion distribution information of stains and clothes in the washing process of the washing machine cannot be completely disclosed. It is unknown that the essence of washing and protecting clothes in a washing machine is that the clothes move along with a rotary drum and are stained and removed under the action of detergent, water flow and mechanical external force. The process relates to washing and protecting stages such as a water injection stage, a main washing stage, a rinsing stage, a dehydration stage and the like, and the parameter operation condition of each stage is closely related to the final water consumption, energy consumption and time consumption of clothes washed by the washing machine and the clothes taking performance of the washed clothes. Therefore, the key point that the problems of water consumption and power consumption of the existing washing machine and poor clothes wearing performance after washing are effectively solved by deeply exploring the washing and protecting process of the washing machine. However, in practical research, people neglect the operation conditions of each stage of the washing machine washing and protecting process and the adsorption and desorption rule states of stains stained by clothes, but use the washing machine washing and protecting process as a black box to treat, only pay attention to the values of indexes such as water consumption, energy consumption and time consumption at the end of washing and protecting, the cleaning rate of the washed clothes and the like, and pay little attention to the change rules of the washing machine washing and protecting process such as adsorption and desorption, heat mass transmission, motion mechanics and the like and the influence of the change rules on the water consumption, the energy consumption and the time consumption of the washing machine and the service performance of the washed clothes.
Therefore, in order to thoroughly solve the problems of large water consumption, energy consumption and time consumption in washing and protecting of the washing machine and poor clothes wearability after washing, the fluid dynamics of the washing and protecting environment, the physical characteristics of the clothes and the adsorption and desorption rules of the clothes and stains and the like in the clothes washing and protecting process must be deeply researched to master the change rule of the process behavior. The basis for the research is that the clothes washing and protecting process of the washing machine is required to be visualized, and the operation parameters can be dynamically regulated and controlled according to the field operation condition of the washing and protecting process and the washing and protecting requirement of quality improvement and efficiency improvement. Therefore, the invention provides a visual dynamic feedback measurement and control method and a system for the research of the clothes washing and care technology. Not only can really master the change rule of the clothes characteristics in the clothes washing and protecting process theoretically; the relation between the clothes washing and protecting effect (appearance grade and mechanical property) and the washing and protecting parameters is mastered, the conclusion can be utilized to optimize the washing and protecting program, update the washing and protecting technology, reduce the washing and protecting water consumption and energy consumption, improve and predict the washing quality of clothes, realize the intelligent regulation and control of the whole process, and really realize the purpose that various washing and protecting requirements of users are met.
