Abstract
The invention relates to a washing machine with a water inlet temperature control and display function and a control method thereof. The water inlet temperature of the washing machine can be measured and displayed in real time. The upper limit value of the water inlet temperature can be adjusted and set and can be automatically controlled. When the water inlet temperature exceeds a limit value, a water inlet electromagnetic valve of the washing machine is automatically turned off, water incoming is cut off, and a buzzer gives out an alarm sound immediately to remind a user to lower the water inlet temperature; when the water inlet temperature is lowered to be lower than the limit value, the water inlet electromagnetic valve of the washing machine can be automatically turned on, water incoming recovers, and meanwhile the buzzer stops alarming. The water inlet temperature can be effectively controlled, the requirement of different kinds of clothes for the best washing water temperature is met, the phenomenon that the cloths are scalded by water with too high temperature is avoided, the cleaning effect of a washing agent is sufficiently achieved, the cleaning ratio of the washing machine is effectively increased, and the structure of the roller washing machine is simplified.
Description
Technical field:
The present invention relates to washing machine field, be specifically related to a kind of washing machine and the control method thereof that there is control and show inflow temperature function.
Background technology:
Under current background technology condition, washing machine is all that supply running water carrys out washing clothes, because the temperature of running water is lower, thus the decontamination effect of washing agent can not be made to be not fully exerted, the best washing water temperature requirement of clothing can not be reached, thus cause the clean inefficiency of washing machine.Roller washing machine is in order to improve clean efficiency, product function is provided with electric heating function, slurry in cylinder can be heated, improve slurry water temperature, to give full play to the decontamination effect of washing agent, meet the best washing water temperature requirement of clothing, and then improve the clean efficiency of washing machine, but this also allows the structure of roller washing machine become complicated, adds manufacturing cost simultaneously.
Along with the development of society and the progressively raising of people's living standard, use hot water progressively to become universal phenomenon in daily life, carry out washing clothes directly to washing machine supplying hot water, also progressively will become universal phenomenon.But the temperature conditions that given full play to of detergent washing effect limits, and, for different types of clothing, the requirement of its best washing water temperature is also different, and this just needs to take effective method, realizes the control to inflow temperature of washing machine.
Summary of the invention:
In view of aforementioned background art present situation, the object of the invention is, provide a kind of have control and the washing machine of display inflow temperature function and control method thereof, can measure in real time and show the temperature of washing machine inflow.Numerical value can be limited to the upper limit of inflow temperature of washing machine to preset: or according to different washing modes, inflow temperature upper limit restriction numerical value is set in advance among controlling program of washing, have selected washing mode and also just have selected inflow temperature upper limit restriction numerical value; Or numerical value can be limited to the inflow temperature upper limit as required and carry out artificial adjustment setting.This washing machine and control method thereof, numerical value can also be limited according to the inflow temperature upper limit of setting, realize the automatic control to the inflow temperature of washing machine upper limit: when inflow temperature exceedes the inflow temperature upper limit restriction numerical value preset, washing machine can cut out entering water electromagnetic valve automatically, cut off to washing machine inflow, meanwhile, interlocking buzzer sends chimes of doom, and reminding user reduces inflow temperature.When inflow temperature is reduced to after lower than inflow temperature upper limit restriction numerical value, automatically the entering water electromagnetic valve of washing machine can be opened, recover to washing machine inflow, until the water level in washtub arrives the designated water level of washing procedure, washing machine enters in washing procedure immediately and starts working, meanwhile, buzzer stop alarm of interlocking pipes.
In order to realize foregoing invention object, the technical scheme that the present invention takes is:
On washing machine, newly increase temperature sensor, temperature measurement signal transmission line, temperature controls and display information process unit, Temperature displaying signal transmssion line, control signal transmission line, alarm signal transmission line, inflow temperature signalization transmission line, temperature indicator, inflow temperature arrange the assemblies such as button.
On washing machine existing capability basis, newly increase inflow temperature and measured in real time and Presentation Function; The inflow temperature upper limit limits numerical value adjustment function; Inflow temperature transfinites and automatically cuts off inlet function, and buzzer warning prompting function of interlocking; Inflow temperature does not transfinite and automatically recovers inlet function, and buzzer warning function removed by interlocking.
