Benefits of technology

[0008] A further advantage of the present invention, beside the reduction of the overall cost of the machine, is that the detergent dispenser can use the full torque in forward and backward movement of the selector that is available at the actuator in order to overcome any blockage problems.
[0009] The detergent dispenser according to the invention is implemented with the construction characteristics as essentially set forth and described in the appended claims.

Problems solved by technology

The cost of known detergent dispensers is presently high due to the number of mechanical components linked to it.
Moreover the mechanical system for moving the selector is quite complicated and therefore its reliability is not very high.

Embodiment Construction

[0016]FIG. 1 depicts a detergent dispenser 10 which is installed in the usual way in the upper portion of a washing machine (not shown), particularly of a drum-type clothes washing machine or combined clothes washing and drying machine, and is constituted by a drawer-like reservoir 12 provided with a plurality of separate compartments (not shown) intended to contain the various washing detergents and / or rinsing aids to be added in a selective manner into the wash tub of the washing machine where they will be used for carrying out the various steps and phases of each selected clothes washing process. The drawer-like reservoir 12 is insertable in a box shaped recess 12a installed in the front portion of the washing machine, just below the top surface of the machine. As it can further be seen, a hose 14 is in communication, downstream electrical on-off valve 16, with a nozzle 18 inside the recess 12a which directs the water flow towards a rotating selector 20 placed inside the recess 1...

Abstract

A washing machine having a detergent dispenser provided with a plurality of separate compartments for containing wash and / or rinse products to be added into the tub of the machine, such detergent dispenser including a rotating selector capable of being displaced into various operational positions by a driver so as to enable the incoming water to selectively flow through each one of the compartment. The driver comprises an electric motor linked through a lever assembly to the rotating selector so that the rotation of the motor is transformed into an oscillating movement of the selector between two predetermined end positions.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a washing machine comprising a detergent dispenser provided with a plurality of separate compartments for containing wash and / or rinse products to be added into the tub of the machine. [0003] 2. Description of the Related Art [0004] Detergent dispensers for washing machines such as clothes washing machines and / or combined clothes washing and drying machines are known in the art. They are divided into a number of separate compartments intended for holding the various pre-wash and main wash detergents, as well as the various rinsing aids such as the bleaching agent and / or the fabric conditioner, wherein each such compartment is capable of being selectively flushed by the water flowing in from the supply mains and directed into the compartment by a suitable rotating compartment selector, which is capable of being displaced into its various operational positions by a suitable linkage ope...
