The output end connection signal output apparatus 5 of circuit 44.
By technical scheme, liquid level sensor 3 can be in the case of discord detergent contact, detection washing
Detergent in agent drawer 2 has stateless, simple in construction, and reliability is high.
The operation principle and use process of the box component for washing agent 100 of the present invention are as follows：
Putting detergent in detergent memory block into detergent drawer 2, detergent will be present in detergent drawer 2
Exist in simultaneously in the accommodating chamber 202 of the second protuberance 21.Behind insertion drawer seat 1 of detergent drawer 2, detergent drawer 2
The second protuberance 21 be inserted into drawer seat 1 the first protuberance 11 in.There is electricity in the outside of the first protuberance 11 of drawer's seat 1
Appearance formula liquid level sensor 3.There are three kinds of materials so between the emitter stage 31 and receiving pole 32 of capacitance level transducer 3,
One is detergent, and two be the plastics of detergent drawer 2 and drawer's 1 box wall of seat, and three be the air in gap.The dielectric of three kinds of materials
Constant is known.Detergent dielectric constant is 81, and plastic dielectric constant is 2.2, and the dielectric constant of air is 1.Obviously washing
Much higher than the dielectric constant of plastics and air of the dielectric constant of agent, that is to say, that the dielectric constant of detergent determines electric capacity
The dielectric constant of 3 liang of interpolars of formula liquid level sensor.Liquid level of the detergent in the accommodating chamber 202 of detergent drawer 2 is to liquid
The capacitance of level sensor 3 plays a decisive role.
When detergent is full of the accommodating chamber 202 of detergent drawer 2, the receiving pole 32 of liquid level sensor 3 sense compared with
High capacitance, by the pull-up resistor 41 of series connection, the raising of capacitance can reduce capacity reactance.So in pull-up resistor 41
The voltage U at two ends will be raised, by amplification, be corrected, and filtering reaches predetermined voltage（Such as 5V）.
When detergent is reduced to predetermined value, the cleaning solution liquid level in accommodating chamber 202 will also decrease, liquid level sensor
The capacitance diminished that 3 receiving pole 32 is sensed, by the pull-up resistor 41 of series connection, the reduction of capacitance can improve electric capacity
Reactance.So the voltage U at the two ends of pull-up resistor 41 will be reduced, by amplification, correct, filtering, so as to detect output
Magnitude of voltage, so as to determine a need for supplementing detergent.
The washing machine of embodiment, including the detergent of embodiment according to a first aspect of the present invention according to a second aspect of the present invention
Case assembly 100.
Washing machine according to embodiments of the present invention.It can accurately judge whether to require supplementation with detergent, be easy to washing machine
Use, improve the service efficiency of washing machine, and for detecting that the liquid level sensor service life of detergent is long, reduction is safeguarded into
This.
