摘要:
Filter unit for aquariums (1), designed to allow easy maintenance by an operator, comprising, in a container (100): - a filtering path, extending between an entrance (2a) and an exit (2b) of fluid, for the circulation of a flow of liquid; - a mechanical filter (4) positioned along said filtering path to intercept the flow of liquid circulating therein, said mechanical filter (4) having an entrance surface (4a) orientated upstream of the filtering path; - at least one scraper member (5a) designed to perform cleaning of the mechanical filter (4), detaching impurities accumulated on said entrance surface (4a) by means of scraping; and - means for promoting a relative motion between scraper member (5a) and mechanical filter (4) causing said scraping of the entrance surface (4a) of the mechanical filter (4).
摘要:
A connection device (4; 104) for a circulator is described, comprising a connection socket (5; 105) and connector (6; 106), wherein the connector (6; 106) and the connection socket (5; 105) comprise connection means and connection counter-means, respectively, which may be mated with each other, in order to provide for a connection between said connector and said connection socket, the connection means and counter-means respectively comprising: - guided insertion means and counter-means for the guided insertion of said connector into said connection socket, - locking means and counter-means for irreversibly locking said connector with said connection socket. Furthermore, a circulator for a boiler apparatus, a connector for a circulator and a connection socket for a circulator, pertaining to said connection device, are described.
摘要:
A support (200) is described for fixing an electric motor (3) to a tub (6) of a washing machine (1) or similar household appliance. The electric motor (3) is of the type with external rotor (70), for driving in rotation a drum (2) supported in the tub (6); the electric motor (3) is provided with a control circuit board (100) associated with a heat dissipator (33). The heat dissipator (33) is integrally formed with the support (33).
摘要:
A pump driven by a synchronous electric motor and comprising a device for transmitting motion between the rotor of the motor and a working part. The device for transmitting motion comprises at least two motion transmission couplings which mutually cooperate in a kinematic series, Each coupling is constituted by at least one driving element which is eccentric with respect to the rotation axis and is rigidly coupled to a first component of the motion transmission system and by at least one driven element, which is also eccentric with respect to the rotation axis and is rigidly coupled to the component arranged kinematically after the preceding one. The angle covered by the elements of each coupling is, as a whole, less than a round angle. The intermediate components of the kinematic transmission have both a driven element and a driving element for receiving the motion from the preceding one and transmitting it to a subsequent one.
摘要:
A permanent-magnet rotor for external-rotor electric motor (1) particularly for washing machines of unusual silence comprising a cup-shaped support structure (6) having a bottom (7) and a side wall (10) and a plurality of magnetic poles (12) arranged in the support structure (6) and arranged along said side wall (10), with elastomeric material interposed between said magnetic poles (12) which forms with them a massive structure (14) of uniform thickness.
