A dishwashing machine comprises a wash tub (3), an electric pump (87) for supplying water from a bottom (3a, 88) of the tub (3) to a sprinkler system (83-86), a switchable device (40), operatively set downstream of a delivery section of the electric pump (87), for controlling supply of water to the sprinkler system (83-86), a water-storage system (30, 45, 46, 50) comprising a tank (30) and a control system including control means for issuing a command for start-up of at least one program for treatment of the dishes that includes at least one step of charging water from the water mains to the tub (3), at least one step of treatment of the dishes, and at least one the step of filling of the tank (30). The switchable device (40) comprises a casing (41), mounted displaceable within which is a distributor member, which can be actuated by an actuator for assuming a plurality of operating positions, amongst which at least one position of opening a first outlet (44), for supplying a first sprinkler (83), and of simultaneously closing another outlet (43), for supplying a second sprinkler (84). The casing (41) of the switchable device (40) has a third outlet (45) that is always open; i.e., it is open irrespective of the operating position assumed by the distributor member. The third outlet (45) is connected via a third pipe (46) to a first opening (39a) of the tank (30) that functions alternatively as inlet and as outlet for the water with respect to the cavity of the tank. Between the third outlet (45) and the first opening (39a) of the tank (30) valve means (50) operate, which can be controlled independently of the switchable device (40).
摘要:
The present invention relates to a method for detecting a rinse aid agent in a rinse liquid of a washing machine (1) for household use, in particular a dishwasher, said washing machine (1) comprising: - a control system (SC), in particular of the electric or electronic type, for handling and controlling the operation of the washing machine (1), said control system (SC) being adapted to implement at least one rinse program; - a tub (2) in which dishes are treated by means of a rinse liquid, in particular water, added with a rinse aid agent during said at least one rinse program; - sensing means (5a, 5b, 5c) associated with said tub (2) and connected to said control system (SC) for detecting the degree of turbidity of the rinse liquid in the tub (2). The invention is characterized in that said method is executed by said control system (SC) and comprises the steps of: a) taking a first measurement (M1) of the degree of turbidity of the rinse liquid in the tub (2); b) executing a step of releasing (R) the rinse aid agent into the tub (2); c) taking a second measurement (M2) of the degree of turbidity of the rinse liquid in the tub (2); d) comparing said first measurement (M1) with said second measurement (M2); e) verifying the existence of a predefined increase of the degree of turbidity of the rinse liquid in the tub (2) for the purpose of detecting the presence of the rinse aid agent in said tub (2).

A method of washing dishes by means of a dishwasher, comprising a plurality of racks placed in a washing compartment and intended to support the dishes during the wash, said method being characterised in that the dishwasher implements a procedure comprising the steps of: a) selecting the wash parameters according to at least: - a first input concerning the type of cycle to be implemented, said first input being selectable from a discrete list; - a second input concerning the rack on which the dishes to be washed are positioned;
摘要:
A dishwasher comprises: - a washing compartment (2) designed to accommodate the articles to be washed; - spraying means (3) for spraying a washing liquid in the washing compartment (2); - a motor-driven pump (4); - ducting means (5) for connecting the washing compartment (2) and the spraying means (3), said pump (4) being located along the ducting means (5) in order to pump the washing liquid from the washing compartment (2) to the spraying means (3); - means (6) for measuring at least one physical property of the washing liquid, comprising a sensor (60) located in the washing compartment (2) or along the ducting means (5) and designed to detect the dirtiness of the washing liquid at the sensor (60). At least during each reading performed by the sensor (60) for measuring the dirtiness of the washing liquid, the dishwasher (1) adopting a first operating reference condition in which the flow processed by the pump (4) substantially always adopts the same predetermined value.

摘要:
A dishwashing machine has a structure that comprises a base (2) and a wash tub (3) supported by the base (2). The machine (1) has an auxiliary functional system, such as a system for drying dishes or a liquid-storage system, which comprises a hollow body (31) with a first portion (34) that is generally vertical and faces a stationary side wall (3d) of the tub (3). The hollow body (31) has a second portion (35) that is generally horizontal and faces the upper wall (3b) of the tub (3), in which a first opening is defined. The upper wall (3b) of the tub (3) has a through opening to which the first opening of the hollow body (31) is operatively coupled, the second portion (35) of said body (31, 31') being secured to the upper wall (3b) of the tub (3) at the aforesaid through opening.

摘要:
A dishwashing machine (1) has a control system (17) including command means (17a) for controlling starting of a treatment program that includes at least one loading step, at least one heating step and at least one treatment step. The control system (17) is configured for controlling loading means (6), an electric pump (12) and heating means (15) during the execution of a treatment program, such that: - during the loading step a substantially predetermined amount of water is loaded in the tub (3); - during the heating step water loaded in the tub (3) is heated up to a substantially predetermined temperature; - during the treatment step the electric pump (12) is driven at a treatment speed for supplying heated water from the bottom (3a, 14) of the tub (3) to a sprinkling member (8), so as to render operation of the first sprinkling member (8) effective for the purposes of treating dishes.
The machine comprises means (12; 13) for supplying the sprinkling member (8), during the heating step at a reduced pressure, which is lower than the minimum pressure required to render operation of the sprinkling member (8) effective, causing at the same time a water circulation among the electric pump (12), the sprinkling member (8) and the bottom (3a, 14) of the tub (3).
