摘要:
Dishwashing machine comprising a valve (7) which is open during a water inlet phase, and a circulation pump (11) which is energized during the water inlet phase. A control arrangement is driven by a signal (V) which is proportional to the outlet pressure of the circulation pump so as to close the inlet valve (7) when signal variations decrease below a pre-determined value. The circulation pump (11) is driven by a single-phase asynchronous motor (14) with a phase-shift capacitor (15) from which the signal (V) is derived. A further signal (U) can be derived from said capacitor (15) to drive the control arrangement so as to determine the correct de-energization of a discharge pump (18).
摘要:
Es wird eine Vorrichtung (164) zur Niveauregelung in einem Fluidtank (122, 132, 144) vorgeschlagen, wobei der Fluidtank (122, 132, 144) eingerichtet ist, um einen Vorrat eines Fluids aufzunehmen. Die Vorrichtung (164) umfasst mindestens eine von dem Fluid durchströmbare Förderleitung (182) mit mindestens einer mit dem Fluidtank (122, 132, 144) hydraulisch verbundenen Steueröffnung (188). Die Steueröffnung (188) ist eingerichtet, um bei Überschreiten mindestens eines Mindestniveaus (190) in dem Fluidtank (122, 132, 144) ein Ausströmen von Fluid aus der Förderleitung (182) in den Fluidtank (122, 132, 144) zumindest weitgehend zu verhindern und wobei die Steueröffnung (188) weiterhin eingerichtet ist, um bei Unterschreiten des mindestens einen Mindestniveaus (190) in dem Fluidtank (122, 132, 144) ein Ausströmen von Fluid aus der Förderleitung (182) in den Fluidtank (122, 132, 144) zu ermöglichen.
摘要:
A dishwasher (10) is provided with a flapper valve (60) for directing water from a recirculation pump (34) to spray arms (18) or a drain (48). The valve (60) is spring (62) biased toward a recirculate position and solenoid operated to a drain position. An inlet (32) of the pump (34) is provided with a downwardly curved suction pipe (35) having a generally horizontal bell mouth (33). The dishwasher (10) has a sump (14) separated into a pump chamber (30) and a collection chamber (28). The pump inlet (32) is located in the pump chamber (30) and has a mouth (33) that is located below a level of the bottom of the collection chamber (28). Wash liquid is pumped through a venturi (42) in the collection chamber (28) to a drain (48).

Dispositif de sécurité pour appareils domestiques à circulation d'eau, comprenant un réservoir de liquide, une commande de remplissage, une vanne d'admission (32) apte à s'ouvrir par l'intermédiaire d'une commande à programme et à se fermer par l'intermédiaire de la commande de remplissage et/ou de la commande à programme, une pompe de vidange (33) et un dispositif de commutation du niveau de sécurité (10), dans lequel un flotteur est disposé dans une chambre à circulation de liquide communiquant avec le réservoir de liquide, munie d'une ouverture d'admission d'eau, et actionne, en position de connexion, un interrupteur qui met en circuit, en cette position de connexion, la pompe de vidange (33) et, le cas échéant, ferme la vanne d'admission (32), le flotteur (16) étant maintenu, en position de repos, à une faible distance (a) au-dessus du niveau statique (3) de remplissage du réservoir de liquide, et de façon que l'interrupteur (17) sollicité par le flotteur (16) mette hors circuit la pompe de vidange (33) lorsque la position de repos est atteinte.
摘要:
A laundry washing machine comprising a tub (4), a drum (5) for containing the laundry, a collector (12) for collecting the laundering liquid containing a heater element (14) and a thermostatic sensor (15), further comprising a recirculation pump (17) connected to said collector (12) and to said tub (4) via a recirculation conduit (16) for repeatedly recirculating the laundering liquid to the tub (4) so as to spray it onto the laundry. The machine is further provided with pressostats (23, 36) for carrying out «intensive» and «delicate» washing programs in the conventional manner, and with a number of pressostats (21, 22) for carrying out «intensive» washing priograms at reduced levels of the laundering liquid introduced into the tub (4), such programs being carried out by recirculating the liquid to the tub. In this manner one obtains optimum consumption of water, detergents and electric energy for ayn type and amount of laundry introduced into the drum (5) of the machine.
摘要:
A clothing treating apparatus and a method of controlling such an apparatus are provided. The clothing treating apparatus may make use of a draining function which may be automatically or manually performed after determining whether or not water received in a detachable water supply tank may be re-used or not.
