Abstract
The washing machine capable of displaying water quality state has one bichromatic LED assembly to show water quality through the brightness. The washing machine includes detector, display and microprocessor. The detector detects the hardness of washing water, detergent amount and temperature; the display has LEDs on or off based on the detected result; and the microprocessor compares the detected result with set reference and controls the display according to the detected result. According to the display, the user can know the water quality state determined with the hardness of washing water, detergent amount, temperature and other factors and then regulates to raise washing efficiency.
Description
Technical field
Washing machine is closed in the present invention, particularly be a kind of washing machine that shows water quality condition.This washing machine form the light emitting diode combined body can show two kinds of looks in appearance, bright or dark by above-mentioned diode outwards represented the water quality of washings.
Background technology
Fig. 1 is conventional laundry apparatus structure section figure, with reference to Fig. 1 washing machine structure is described.Usually automatic washing machine washs in a washing tank, cleans, and dehydration waits all laundry strokes.When this washing machine carries out washing agent input and the conversion of laundry stroke automatically, carry out operations such as water supply and drainage.Automatic washing machine is by possessing washing tank 10, feed-water valve 30, and checkout gear 20, motor 40 is formed, and utilizes various checkout gears 20, and microprocessor carries out (not shown).Washing tank 10 is made up of inner casing 1 and outer shell 2, and possesses agitator.Feed-water valve 30 is used for the feedwater and the draining of washings, and motor 40 drives washing tank 10.Microprocessor is according to the value of above-mentioned detection device 20 outputs, and control detergent amount and selection washing procedure are controlled whole washing process.
The checkout gear 20 that uses on the washing machine, it is different to press type.Checkout gear 20 detects the detergent concentration detecting sensor of detergent concentration in the washings by the condensate tank of dehumidifier that detects the washings water level, detects the compositions such as hardness detection sensor of washings hardness.Microprocessor receives the value that each checkout gear detects, these value combination conversion back decision washing procedures.
But when not showing the washing water quality situation of checkout gear detection, the user can't know wash conditions, thereby all uses habitual mode of washing at every turn.Cause the waste of washing efficiency low or the energy and washing agent.Such as, hardness of water is different by the area.Corresponding to washings, should suitably adjust detergent amount and wash temperature with different hardness.When could improve detersive efficiency like this, conserve energy.But, do not know that the user of wash conditions might unconsciously throw in very few or too much washing agent, and utilize overheated or cold excessively washings to wash.Thereby cause the low or energy waste of detersive efficiency.
Summary of the invention
Technical problem to be solved by this invention is that a kind of washing machine that can represent water quality condition is provided.That is, form the light emitting diode combined body can show two kinds of looks in appearance, bright or dark by diode outwards represented the water quality of washings.Allow the user judge water quality condition easily, thereby allow the user select suitable mode of washing.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the washing machine that shows water quality condition comprises checkout gear, display part, microprocessor is formed, and checkout gear detects hardness of washing water, detergent amount and temperature, the result that display part detects according to checkout gear, make not homochromy led lighting or close, microprocessor compares testing result and the washing machine standard value set, and presses comparative result control display part.
In sum, the invention has the beneficial effects as follows: can show the washing water quality state.After this washing machine comprises the various values of water quality condition by the checkout gear detection, compare with standard value, make the above-mentioned light emitting diode combined body that can send 2 kinds of looks be in bright or dark state by comparative result, allow the user judge water quality condition easily, improve the efficient of washing force and each washing stroke, save energy.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 2 is the washing machine pie graph of demonstration water quality condition of the present invention.Fig. 3 shows the washing machine display part schematic diagram of water quality condition for the present invention.At first, checkout gear 100 is located at a side of outer barrel of washing machine, detects hardness of washing water, detergent concentration and temperature.Checkout gear 100 comprises the hardness detection sensor 110 that detects washings hardness, detects the detergent concentration detecting sensor 120 of detergent concentration in the washings, detects the temperature detection sensor 130 of temperature of washing water and forms.
Hardness refers to, the metal divalent cation (Ca that dissolves in the water
2+, Mg
2+, Fe
2+, Mn
2+, Sr
2+Deng) concentration (mg/L), be reduced into corresponding with it calcium carbonate (CaCO
3), a kind of index of representing with mg/L or ppm.That is the ratio of mineral matters such as calcium that contains in the premium on currency or magnesium.
Usually, hardness 1 degree is corresponding to 18ppm, and hardness of water is lower than 6 and is soft water when spending, and spends greater than 6 and then is hard water.Under the effect of the surfactant of hardness in self-contained mineral composition of washings and washings etc., can change.
The value that microprocessor 200 detects according to checkout gear 100, the apparent display part 300 of control washing machine makes the water quality condition of light emitting diode combined body 310 by different colour specification washings.
In the present embodiment, two kinds of looks are respectively green and red, with of all kinds bright/dark/bright repeatedly form such as dark, represent multiple information.
In addition, before the comparative result that receives comparing section 210, in order to represent this state, display control unit 220 sends control signal to above-mentioned light emitting diode combined body, makes it bright repeatedly dark.
