Housework Relief – Monitoring done by Machines
Faster and more convenient than in the past. Automated and program-controlled. Doing the laundry can be so easy. Modern washing machines and dryers make housework a lot easier.
People increasingly use liquid detergents in convenient single-use or reusable cartridges. Permanently installed storage tanks are equally popular.
These machines, however, require level sensors that measure the supply of detergents. Automation is pointless without clear information about the status of the storage tank.
Liquid detergents and softeners pose major challenges to the sensor system of a washing machine. They cause films to build up on the inner wall of the container. .
With its [corTEC® technology] EBE sensors + motion offers a solution that faultlessly determines the filling levels of highly adhesive and film-forming liquids. As one of only a few providers worldwide, EBE offers a technology which is both up to the requirements of viscous liquids and suitable for volume production.
The development of [level sensors] based on the corTEC® technology is made according to the requirements of the customer. [Please send your requests and specifications for your project to EBE. Ask EBE for a suitable solution] .
EBE also enables the appliance to recognize the complete tank or a detergent dispenser automatically. In this way it is possible to check if the container is pushed in completely and properly.
Safety by Capacitive Sensor Systems
Users of washing machines want to be sure that everything is ok during their absence resp. during operation. To give an example, the appliance must not leak. In the event of failure aquastop safety systems prevent any water leakage.
EBE sensors + motion offers manufacturers of washing machines a sensor technology that reliably supports aquastop systems: the capacitive level measurement based on the [capaTEC® technology] .
Compared to conventional float gauge/microswitch solutions the capacitive level measurement saves precious installation space. The sensor technology requires only little space.
capaTEC® sensors need no movable components such as floats. Therefore, no sensor component can get caught or wear out. In conventional aquastop systems there is the danger of movable parts getting jammed and impairing the safety function.
Reliable Monitoring in the Dryer
In dryers capaTEC® detects the fluid level in the condensate tank.
The capacitive technology avoids the disadvantages of conventional resistive sensor systems. The capacitive level switch has no direct contact with the fluid. Fluff in the condensate does not impair its function in any way.
Application-Specific Solenoids for Valve Control
Powerful solenoids control the valves in washing machines. They switch resp. actuate the inflow and drainage controls. Apart from the high actuating power a long service life and 100% reliability are required. Frequently, solenoids are located in difficult to access resp. completely closed parts of the machine. It is difficult or virtually impossible to replace them.
For decades the delivery program of EBE sensors + motion has included solenoids which meet these special requirements of washing machines.
Appropriate actuating solenoids can be modified or developed for individual applications and appliances. EBE develops design, actuating power, switching speed and further features according to the parameters and specifications of the customer. Thermal protection devices and rectifiers ensure a safe and lasting function. Beyond that EBE takes special insulation classes and UL-compliance into consideration.
