摘要:
A device for controlling or preparing a mixture of fluids, in particular a food or domestic mixture, comprises at least two addition ducts for a first and a sec and fluid getting in (5B), an area where the two fluids are mixed (23), so as to ob tain a mixture getting out, and control means (SC) for flow rate adjusting ele ments (13B) for the first and second fluid, arranged on the addition ducts. The invention envisages detecting means (29) for one or more physical-chemical properties of at least one among said mixture, first fluid and second fluid. In a preferred embodiment the detected physical-chemical quantity is pH.
摘要:
Household apparatus, in particular a washing machine, comprising an electrochemical treatment device (20), in particular a water softener, in which two electrodes (20B,20C) are provided, with ion exchange membranes (C,A) arranged between them for delimiting a plurality of channels (CE,CC,CP). According to the invention, means ( + ,- ) are provided for periodic filling of some channels (CE,CC,CP) of the electrochemical device (20) with a cleaning substance or solution, the latter being apt to dissolve and/or remove saline precipitates eventually formed inside the device .
摘要:
A device (1) comprises a body (E1, E2) defining a space (P) for the passage of a fluid, detecting means (32') for at least a hydraulic or chemical-physical property of the fluid passing through said space (P), and a control system. The connection between the detecting means (32') and the control system comprises a wireless data transmission circuit (SWG) connected to the detecting means (32'), and a corresponding receiving circuit (RWG) interfaced to the control sys tem. The transmission system can advantageously be a radio-frequency passive electric circuit (34, 36) without independent power supply.
摘要:
Household apparatus using a fluid, comprising a purifying system in which at least a substance must be removed from at least a portion of said fluid, said system comprising: an elctrochemical, electro-dialysis or electro-osmosis cell (20); collecting means (P, S, AC) of saif fluid; controlling means (SCE). According to the invention, recycle means are provided (12, 22, 23, 15, 21, 24), to realize a substantially closed circuit and/or continuous circulation of said fluid between the collecting means (P, S) and said cell (20), until a preset purifying value of the fluid is reached.
摘要:
Arrangement for electrochemical purification or treatment of a liquid, utilizing an electrochemical cell (20), where two electrodes (20B,20C) are provided with ion exchange membranes (C,A) arranged between them to delimit a plurality of channels (CE,CC,CP). According to the invention, at least a few channels (CE,CC,CP) have respective second electrodes ( + ,- ) associated to them for obtaining a cleaning substance or solution, the latter being apt to dissolve and/or remove likely residuals and/or scaling deposited inside the cell (20).
