Abstract
Description
- The present invention relates to a detergent supply unit for a laundry washing machine for the supply of particulate and/or liquid detergents and of additives to the washing tub of the machine.
- At present all laundry washing machines are provided with a detergent supply unit disposed in an upper portion of the machine and formed with a number of separate compartments for containing additives and detergent in particulate and/ /or liquid form, said compartments being connected to a conduit leading to the washing tub.
- The detergent supply unit is provided with per se known control devices adapted to intercept the water fed to the supply unit and to selectively divert it to individual compartments for removing therefrom the detergent or additive contained therein and transferring it to the washing tub.
- For achieving this effect, the introduction of the water into the actually employed detergent supply units is carried out in two different modes.
- According to a first mode, the water is separately supplied to each compartment of the supply unit so as to impinge on the bottom and/or on a part of the interior wall surface of the respective compartment. This system makes use of the dynamic pressure of the water for removing the detergents from the compartments within a sufficiently short time, but is incapable of ensuring a thorough cleaning of the supply unit, so that the individual compartments have to be periodically cleaned.
- According to the second mode, the water is supplied to a distributor disposed above the compartments of the supply unit and provided with a number of separate internal passages communicating with individual compartments through nozzles or the like.
- According to this system, the water is thus suppied in the form of a number of jets impinging on substantially the entire interior wall surface of the respective compartments so as to ensure thorough cleaning thereof. As on the other hand the cinetic energy of the water is dispersed over a relatively large area, emptying the various compartments of their contents takes a considerably long time.
- In addition, both of the described systems are only suitable in the case of compartments having a large cross-sectional area and a limited height, and are thus badly suited for employ in laundry washing machines of the top-loading type or of compact construction.
- It is an object of the present invention to eliminate the above noted shortcomings by providing a detergent supply unit permitting the detergents and additives contained therein to be rapidly and completely transferred to the washing tub of the laundry washing machine, so as to ensure optimum utilization of these substances.
- For attaining this object, the invention makes use of the principle of contemporaneously introducing the water into the supply unit in two directions, so that a first portion of the water impinges on the bottom with considerably dynamic energy so as to promote the discharge of the detergent or additive from the compartment, while another portion of the water sweeps the interior wall surface of the respective compartment so as to ensure its being thoroughly cleaned.
- The supply unit according to the invention is additionally provided with a conduit for diverting part of the water supplied thereto so as to achieve recirculation thereof under pressure for permitting any detergent accumulated in the discharge portion of the machine to be efficiently recuperated.
- These and other objects are attained according to the invention in a laundry washing machine comprising a detergent supply unit provided with respective inlets for the supply thereto of cold and hot water from the water mains and connected to a washing tub the lower portion of which communicates with a discharge unit, said detergent supply unit comprising a container divided into a number of separate compartments adapted to contain detergetns and additives, and a disstributor adapted to be removably mounted on said container and provided with separate internal passages communicating with the various compartments, a control piston being adapted to be actuated by the program unit of the machine for selectively diverting the water to each of said internal passages.
- According to the invention, a detergent supply unit of the type defined above is characterized in that at least one of said compartments is provided with conduit means adapted to introduce the water also adjacetn the bottom of said compartment, collector means being connected to said discharge unit for causing a part of the supplied water to recirculate therethrough.
