摘要:
Control system (8) for a household appliance (1), at least adapted to control a water treatment system (2), the latter comprising ion-exchange resins. The control system (8) being adapted to establish different hardness levels of water to be used in said household appliance (1) and, for each established hardness level, when it is necessary to carry out a procedure for regenerating the resins of the system (2). The control system (8) comprising: at least one storage medium (82) containing information and data about the management and control of the system (2); and at least one processing unit (81) adapted to process the data contained in said storage medium (82), for the purpose of appropriately controlling the system (2) so as to be able to change the hardness of the water to be used in said household appliance (1) and conveniently request the execution of a procedure for regenerating the resins of said system (2). The storage medium (82) is adapted to allocate memory for at least two threshold values for each hardness level established by the control system (8). Said at least two threshold values corresponding to as many water quantities to be supplied to the system (2), whereupon it is necessary to supply a suitable quantity of a regeneration liquid or fluid in contact with said ion-exchange resins of said system (2).

A fuel filter comprising a sleeve (11) adapted to be fastened at a suction end (4a) of a fuel pump (4) and defining a fuel passage opening (11a), an envelope (13) fastened to the sleeve (11) and at least partially formed by a filtering membrane, the filtering membrane comprising a membrane portion (13a) completely covering the fuel passage opening (11a), and a wicking body (15) made of spongy material, housed within the envelope (13) and arranged in such a way as to completely cover the fuel passage opening (11a).
摘要:
A sensor device for optically detecting characteristics of a fluid. The device includes a housing with a base portion from which first and second appendages extend at least partially facing one another, and between which in use a fluid is present, and first and second optoelectronic devices adapted to transmit and receive radiation, respectively, mounted at the first and second appendages of the housing, respectively. The arrangement is such that in use a radiation beam transmitted by the first optoelectronic device propagates in an optical path which includes a portion crossing the fluid between said appendages and reaches the second optoelectronic device. This optical path includes at least one reflecting surface made integrally in an appendage of the housing and adapted to deflect the radiation beam between the associated optoelectronic device and the fluid crossing portion.

An integrated component for supplying and treating water for a dishwashing machine having a washing tank includes a monolithic body of plastics material, within which an inlet conduit for water, a chamber containing substances with water-softening properties, into which the inlet conduit leads, a salt-containing reservoir arranged in the lowermost portion of the body and having a filler tube for loading the salt and to be connected to the washing tank, a compartment for blowing out vapours having an inlet opening to be connected to the washing tank and an outlet opening, an outlet conduit of water, a conduit for supplying water to the reservoir to produce the brine, and a conduit connecting the reservoir to the chamber are defined. The monolithic body has at least one protrusion, to which a sealing gasket is associated, for the direct connection within an opening of corresponding shape of the washing tank.
摘要:
A door-lock system for a household appliance, such as a washing machine and the like, of the type provided with a door, to which a hook is associated, and a member to be moved (C) of said household appliance, such as a washing drum (C) or the like, said door-lock system comprising motor means for operating said member to be moved (C) and a door-lock device, capable of interacting with said hook, to lock said door, characterized in that said door-lock system comprises a control unit, capable of controlling the power supply of said motor means and connected to said door-lock device, so as to control the power supply to hold said hook and to close said door.
摘要:
A door-lock device having a casing, a slider, arranged within said casing, a locking hook with a body and a locking portion, said body having a cam shape which abuts said slider, said locking hook capable to assume a rest position, in which said locking portion is disengaged from said recess, and an operative position, in which said locking portion is inserted, and engaged with, said recess, and pushing capabilities, for keeping said slider in contact with said cam surface, so when said door is closed, said locking hook passes from said rest position to said operative position, said cam shape compressing said pushing capabilities, so that said pushing capabilities accumulate energy and said slider exerts a resistance to the closing of said door, and, then, allowing said pushing capabilities to release said energy, so that said slider exerts a return action on said locking hook and on said door.
