摘要:
The present invention relates to a washing machine, in particular a dishwasher, having a washing agents dispenser with an actuator for dispensing washing agents inside a wash tub of the washing machine, and a wash pump for wash water circulation inside a hydraulic circuit of the machine. The actuator is assembled in a direct fluid connection to the wash pump so that dispensing of the washing agents of the dispenser is driven by the wash pump through the change of the delivery pressure generated by its operation. The present invention provides a saving of the inner resources of the washing machine, which no longer requires an actuator for the sole purpose of dispensing the washing agents in the tub.

The sensor comprises a body in which a diaphragm is mounted so as to define a variable-volume chamber to which a fluid pressure is supplied in use, and a plurality of electrical switches connected to the diaphragm so that the diaphragm can bring about switching of the switches when the pressure in the chamber exceeds corresponding different threshold values which are predetermined by associated calibration means including, for each switch, a respective spring the compression of which can be varied by means of a corresponding reaction member the position of which relative to the body is adjustable.The reaction members are connected rigidly to the ends of an interconnection structure translatable in a guide structure. This guide structure comprises a plurality of laterally-slotted, tubular guide projections, each for guiding a corresponding reaction member, and an intermediate guide projection for guiding the sliding of a central portion of the interconnection structure with which are associated a resilient member tending to bring about a relative movement between the interconnection structure and the body and a snap locating device for restraining the interconnection structure selectively, against the action of the resilient means in one of a plurality of positions relative to the body, in each of which respective different pressure threshold values are associated with the electrical switches.

The device comprises a valve body with an input adapted to be connected to a water supply source, and with at least a first and second output. The body is provided with at least a first and a second electrovalve with direct actuation, whose hydraulic inputs are interconnected with one another and are connected to the input of the valve body and whose outputs are independent or separate and are connected to the first and the second output of the body respectively. The body is provided with a third solenoid electrovalve, for safety purposes, interposed between the input of the body and the inputs of the first and second electrovalves. Control devices are coupled to this third electrovalve such that the latter may be opened/closed each time that the first or second electrovalve is opened/closed. This third electrovalve closes in a delayed manner with respect to the closure of the first and the second electrovalve.

The device (1) comprises a body (2) in which are formed a first and second chamber (14, 15) separated sealingly from each other by a resilient diaphragm (6). The first chamber (14) has an inlet opening (2c) intended to be put in pneumatic communication with the region of a container which is above the liquid; the second chamber (15) communicates with the atmosphere. A winding (8) is mounted in a fixed position in the body (2), on the side opposite the first chamber (14) with respect to the diaphragm (6). A core (11) is coupled to the diaphragm (6) and is movable with respect to the winding (8) such that in operation the inductance of the winding (8) varies as a function of the position of the core.The device also comprises a first spring (12) tending to move the core (11) towards the diaphragm (6), and a second spring (16) tending to oppose the action of the first spring (12). The second spring (16) is positioned in the second chamber (15).

The device comprises a stationary body which has, defined inside it, a passage for a flow of liquid with at least one inlet opening and one outlet opening for the flow and in which at least one valve seat directed towards the outlet opening is defined in the vicinity of the inlet opening and in a middle portion of which a shaped transverse annular surface is formed. A movable body is arranged in the passage and co-operates in the manner of a flow throttling member with the transverse annular surface so as to define for the liquid flowing from the inlet opening to the outlet opening a flow cross section variable depending on the pressure of the liquid at the inlet of the support body. The movable body co-operates moreover in the manner of a obturator with the seat and a return spring tends to push it against this seat away from said shaped annular surface.

The device comprises at least one electrical air pressure threshold sensor, with a body which has an inlet connector; a support structure intended to be fixed in the machine, and to which the body of the pressure sensor is fixed; and at least one duct having one end coupled to the inlet connector of the pressure sensor, and the other end extending into the washing chamber or tub of the machine in such a way that when the level of the washing water in the chamber or tub increases, the water is capable of causing air to be trapped in the duct. The least one duct comprises a length of flexible tube, coupled to the inlet connector of the associated pressure sensor and curved and joined to the support structure in such a way as to form a loop which extends higher than the body of the pressure sensor, and which then continues downwards in the direction of the washing chamber or tub.
