Program is provided with the unit, links to each other with described water cleanliness factor checkout gear, is used for judging according to the cleanliness factor of water determining whether that needs start the water consumption of washing procedure next time and this washing procedure;
And described water cleanliness factor checkout gear includes:
Sender unit is arranged on the washing barrel wall, is used for sending an infrared detection signal to water to be detected;
Signal receiving device is arranged on the washing barrel wall, is used for receiving the infrared reflection signal that described infrared detection signal fires back from water;
Control module, link to each other with signal receiving device with described sender unit, be used for to described sender unit output signal firing order, and after described infrared reflection signal is converted into detected value, the described detected value and the water cleanliness factor table of comparisons of presetting are compared, determine the cleanliness factor of water.
The invention has the beneficial effects as follows:
Embodiments of the invention detect the cleanliness factor of water by utilizing an infrared signal, thereby have realized automatically according to the clean-up performance of water washing times and water consumption being set, and hommization, intellectuality have avoided unnecessary to water, electricity, waste of time.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structured flowchart of an embodiment of washing machine provided by the invention.
Description of drawings
Fig. 2 is the structured flowchart of water cleanliness factor checkout gear among embodiment of washing machine provided by the invention.
Fig. 3 is the scheme of installation of sender unit and signal receiving device among embodiment of washing machine provided by the invention.
Fig. 4 is the circuit theory diagrams of signal processing unit among embodiment of washing machine provided by the invention.
Core of the present invention has been to utilize the principle of reflection of light, because the clean level of water is directly proportional with its albedo to light, water is more muddy, reflects more big; Otherwise water is more limpid, reflect more low, based on this principle, as long as light of Xiang Shuizhong emission, according to the emission degree of strength of water to this light, can judge the clean level of water, thereby judge whether that according to the cleanliness factor of water needs start next time washing procedure and slurry amount.
The specific embodiment
Introduce an embodiment of washing machine provided by the invention in detail below with reference to Fig. 1.
With prior art similarly, present embodiment mainly is made up of wash bucket 1, motor 2 and Based Intelligent Control parts 3 three big essential parts etc.; Different is that the Based Intelligent Control parts of present embodiment also include:
Water cleanliness factor checkout gear 31 links to each other with wash bucket 1 wall, and the water that is used in wash bucket sends infrared detection signal, and judges the cleanliness factor of water according to its reflected signal;
Program is provided with unit 32, links to each other with described water cleanliness factor checkout gear, is used for judging according to the cleanliness factor of water determining whether that needs start the water consumption of washing procedure next time and this washing procedure.
During specific implementation, described water cleanliness factor checkout gear specifically includes:
During specific implementation, described control module 313 can further include:
During specific implementation, described emitter 311 and signal receiving device 312 are respectively transmitting terminal and the receiving terminal of infrared tube U1.What in the present embodiment, infrared tube U1 adopted is TCRT5000 type infrared tube.
During specific implementation, can deposit in the control module, the judgment standard of unit 32 is set as program according to the default judgment standard of people's custom, as: a water cleanliness factor limit value is set, all needs to start washing procedure next time below the limit value at this; And the water consumption that various cleanliness factors need is set, these data all can be according to people's custom setting.
Describe an embodiment of washing machine method of washing clothes provided by the invention below in detail.
The process that present embodiment carries out the once washing clothing mainly includes following steps:
At first, carry out the signal forwarding step, Xiang Shuizhong launches an infrared detection signal, during specific implementation, the square wave of the I/O mouth output 1KHz of control module MCU, the transmitting terminal that drives infrared tube U1 by triode Q1 sends infrared ray, shines and forms reflection in the water that will detect.
Secondly, carry out judgment processing steps, with the strong and weak degree of the reflected signal of described infrared detection signal and default water cleanliness factor table of comparisons contrast, judge the cleanliness factor of water, during specific implementation, after the receiving terminal of infrared tube U1 receives the infrared signal that reflects, this infrared reflection signal is amplified by the base stage that coupling capacitance C1 is input to amplifier tube Q2, the A/D mouth of the control module MCU then colelctor electrode by Q2 obtains signal after the described amplification, after this signal carried out analog-to-digital conversion, can obtain the detected value of digital signal form.
And only need write down the detected value of washing machine under various water clean level by experiment, and water cleanliness factor and corresponding detected value thereof are deposited in the control module, the default water cleanliness factor table of comparisons can be formed.
At last, performing a programme is provided with step, control determines whether that needs start the water consumption of washing procedure next time and this washing procedure according to the cleanliness factor of water, during specific implementation, can deposit in the control module according to the default judgment standard of people's custom, as: a water cleanliness factor limit value is set, all needs to start washing procedure next time below the limit value at this; And the water consumption that various cleanliness factors need is set, these data can be according to people's custom setting.
