Sensors used in washing machine and their functioning by arushi kapurwan on prezi

LIST OF SENSORS EMPLOYED IN THE FUNCTIONING OF WASHING MACHINE Modern machines use thermistors as Temperature Sensors. What can i wash clothes with without detergent Thermistors are low-cost temperature-sensitive resistors and are constructed of solid semiconductor materials which exhibit a positive or negative temperature coefficient. How to hand wash clothes in washer The thermistor’s high sensitivity (typically, –44,000 ppm/°C at 25°C allows it to detect minute variations in temperature which could not be observed with an RTD or thermocouple. How often to wash clothes This switch controls how high the tub fills with water. Wash shirts before wearing The big end of the hose connects to the bottom of the tub, while the small end connects to the switch. How to clean poop stains from baby clothes As the water level in the tub rises, water rises in the hose also; but the air in the hose is trapped, so as the water rises, the air is compressed. How to wash laundry without detergent Washing machines are a common feature today in the Indian household. How to wash knit sweaters washing machine The most important utility a customer can derive from a washing machine is that it saves the effort he/she had to put in brushing, agitating and washing the cloth. Can i wash all my clothes in cold water Inside the housing of this switch is a little piston. How to wash clothes step by step The pressure in the hose pushes the piston up. How to wash your clothes properly When it is raised far enough, it pops up and closes an electrical contact. How to wash black clothes without them fading This set point, where the contact is lost, is adjustable, and in the picture you can see the cam mechanism that is connected to the adjuster knob on the control panel of the washer. How to clean my washing machine with baking soda As the cam turns, it presses a spring against the cylinder, making it harder for the cylinder to pop up. How to clean vintage barbie clothes This means that the water level will have to rise some more before the pressure in the hose will be high enough to trigger the switch. How to wash shirts in washing machine When there is mains supply the transistor Q1(BC558) will be OFF and the capacitor C1 will be charged. When can you stop washing baby clothes When the mains supply fails the transistor Q1 becomes ON and the capacitor C1 discharges through the Q1 to drive the buzzer to produce an alarm. Wash clothes in cold water to save energy The capacitor C2 is the filter capacitor for the bridge. How to wash sweaty gym clothes Diode D2 prevents the discharge of the C2 when mains fails. Should you wash baby clothes before they wear them If D2 is not there, the alarms will remain silent for a time capacitor C2 to fully discharge after the power failure. How to clean workout equipment Automatic Washing Machine Water Shutoff Valves with Leak Sensor are used in residential applications to protect against catastrophic water damage from a burst inlet hose connected to a washing machine in use or unattended. What do you wash dark clothes in hot or cold The signal is transmitted whether the washing machine is on or off, and then opens or closes the hot and cold inlet valves as needed to allow or prevent water from flowing to the washer. When should you wash new baby clothes If it detects a leak, current flow to both the hot and cold water valves are immediately interrupted and closed. How to clean underarm stains on white t shirts A spectrum of methods is currently being used to detect out-of-balance conditions. Washing clothes by hand games At the low end is a combination of mechanical switches that sense when the drum displacement exceeds an established safety threshold. Should you wash your clothes inside out If excessive motion is generated, the drum itself will activate the switches and turn off the machine. How to wash black clothes A more sophisticated approach consists of monitoring variations in the machine’s electric motor torque, rotational velocity, or the amount of power drawn. How to clean clothes without washing In a horizontal-axis machine (front loader), an unbalanced load will generate a gravity-induced torque or velocity ripple during each revolution. What type of water to wash white clothes in This condition can be detected by looking at the motor currents and/or voltages, or the rotational speed (tach) signal available on most washing machine motors. What setting do you wash white clothes on This signal is generally a pulse train whose frequency should be constant at steady speed. How to clean white t shirt stains The signal is fed into the main control unit microcontroller and its frequency is monitored for any variation. How to wash woolen clothes in washing machine A velocity ripple will reflect load imbalance. What temperature should i wash my dark clothes In the presence of an unbalanced load, the tach signal generated by the motor of a front-loading clothes washer exhibits a ripple at a given rotational speed. What to wash dark clothes on The machine can be programmed to shut down or take corrective action if and when the ripple exceeds preset threshold levels symptomatic of an excessive out-of-balance condition that could lead to undesirable effects at higher spinning speeds. How do i clean my washing machine it smells Full transcript
