Description
Technical field
The present invention relates to washing machine field, particularly relate to the washing machine that a kind of liquid detergent self adaptation is thrown in.
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, all without liquid detergent jettison system, is typically necessary and artificially manually throws in liquid detergent.
The amount that liquid detergent is thrown in poorly is controlled, and the liquid detergent of input is too much, water excess when can make to rinse, and the mistake that liquid detergent is thrown in can make clothes not wash clean at least.
