Abstract
The invention discloses a self-adaptive water level adjustment method of a washing machine. An electromagnetic valve is arranged between an external water pipe and a water injection pipe of the washing machine; a liquid level sensor is arranged at the bottom end of a drum of a washing machine body; an infrared distance measurement module is arranged on an upper cover of the washing machine body. When the washing machine requires water, the infrared distance measurement module is used for measuring the distance between the upper cover and clothes in the drum, then the height of the clothes in the drum is calculated, and finally, water is injected according to the calculated injected water volume. The washing machine is simple in structure and convenient to use, the injected water volume is not required to be set, user experience is good, the injected water volume is proper, and the situation that the clothes are not washed clean due to too little water or waste is caused due to the fact that too much water is injected cannot be caused.
Description
Technical field
The present invention relates to washing machine field, particularly relate to a kind of method that washing machine self adaptation water level regulates.
Background technology
Liquid level sensor (static pressure liquid level meter/fluid level transmitter/liquid level sensor/level sensor) is a kind of pressure transducer measuring liquid level.Static pressure throw-in type liquid transmitter (liquidometer) is based on the principle that surveyed fluid pressure is proportional to the height of this liquid, adopt external advanced isolated form diffusion silicon-sensitive element or ceramic capacitive pressure sensitive sensor, static pressure is converted to the signal of telecommunication, then through temperature-compensating and linear correction, change into standard electric signal (being generally 4～20mA/1～5VDC).
Liquid level sensor is divided into two classes: a class is contact, including single flange static pressure/bis-flange differential pressure liquid level transmitter, float ball type level transducer, magnetic level transmitter, throw-in type liquid transmitter, electronic inner float ball fluid level transmitter, electric float level transmitter, capacitive liquid level transmitter, magnetostrictive liquid level transducer, waits upon and takes fluid level transmitter etc..Equations of The Second Kind is contactless, is divided into supersonic level sensor, radar level transmitter etc..
Static pressure throw-in type liquid transmitter (liquidometer) is suitable in the level gauging of the systems such as petrochemical industry, metallurgy, electric power, pharmacy, water supply and sewage, environmental protection and the various media of industry.Exquisite structure, simple adjustment and flexibly mounting means easily use for user and provide conveniently.The standard signal way of outputs such as 4～20mA, 0～5v, 0～10mA are optional as required by user.Utilize hydrostatic principle to measure liquid level, be an important application of pressure transducer.Adopt extraordinary centre with the cable of airway and special Sealing Technology, both ensure that the watertightness of sensor, and made again reference pressure chamber communicate with ambient pressure, thus ensure that the high accuracy of measurement and high stability.
The principle of fluid level transmitter is static pressure measurement principle: when fluid level transmitter puts into a certain degree of depth in fluid to be measured, and sensor is met the pressure formula that liquid level is subject to and is:
Ρ=ρ*g*H+Po
In formula, P is that transmitter meets pressure suffered by liquid level, and ρ is fluid to be measured density, and g is local gravitational acceleration, and Po is atmospheric pressure on liquid level, and H is the degree of depth that transmitter puts into liquid.
Meanwhile, by inducing QI rustless steel, the pressure of liquid is incorporated into the malleation chamber of sensor, then the atmospheric pressure Po on liquid level is connected with the negative pressure cavity of sensor, with the Po at the offset sensor back side, make sensor record pressure to be: ρ * g*H, it is clear that, by measuring pressure P, it is possible to obtain the liquid level degree of depth.
Fluid level transmitter has following functions feature:
1. good stability, full scale, zero-bit long-time stability are up to 0.1%FS/.Compensating within the scope of temperature 0～70 DEG C, temperature drift is lower than 0.1%FS, lower than 0.3%FS in whole permission operating temperature range.
2. having reverse protection, current-limiting protection circuit, both positive and negative polarity connects the anti-transmitter that is damaged from when mounted, send device meeting automatic current limiting time abnormal within 35MA.
3. solid-state structure, without movable member, high reliability, long service life.
4. easy for installation, structurally simple, economical durable.
Existing washing machine is required for setting in advance to use how much water, it is impossible to automatically according to laundry amounts judge use water number, and the selection of water consumption owing to setting is limited, often multiplex water or use water less.
Patent " washing machine " (application number: 201510369589.7 applyings date: 2015-06-29) discloses a kind of washing machine, including: casing；Staving, described staving is located in described casing；And water lev el control panel, described water lev el control panel sets on the housing, and described water lev el control panel includes display screen, described display screen shows Water level trend bar, fluctuating according to the change of input instruction in the upper surface of described Water level trend bar, the water filling height upper surface that sets of described staving is associated with the setting upper surface of described Water level trend bar.
Although the washing machine of invention, user can according to the accounting of medicated clothing thrown in staving and degree of fouling, by regulating the mode of Water level trend bar upper surface, intuitively, clearly select the water filling height of staving to control water injection rate, thus taking into account using water wisely and guaranteeing the double effects of medicated clothing washability.But, this needs for user oneself to regulate water injection rate, it is impossible to be automatically adjusted water injection rate.
