Definitions
- the present invention relates to washers/dryers, and in particular to a washer/dryer provided with an additional condensing circuit to speed up the drying of the laundry at the end of the washing cycle.
- a fan creates an air stream in the circuit and a resistor heats the air circulating in said circuit.
- an electrovalve is opened to admit condensing water into a condensing duct, where the condensing water is kept in suspension by the suction created by the fan.
- the fan receives partially cooled and dried air that is heated again by the resistor and returned to the tank.
- the object of the present invention is to provide a washer/dryer which overcomes said drawbacks.
- This object is achieved by means of a washer/dryer provided with an additional condensing circuit obtained by connecting the detergent drawer to the condensing duct through an expansion chamber and a return pipe.
- Other advantageous features of the present washer/dryer are disclosed in the dependent claims.
- the main advantage of the present washer/dryer is that of achieving a greater condensing effectiveness thanks to the additional condensing circuit that operates in parallel with the primary condensing circuit. This results in a reduction of the drying time, with a subsequently lower power consumption.
- Another significant advantage of this arrangement comes from its structural simplicity that allows to achieve the above-mentioned improvement in effectiveness without affecting the overall size of the machine and with only a minimum increase in manufacturing cost.
- a washer/dryer includes a tank T, closed by a door P, that houses a rotating drum D containing the laundry L to be dried.
- the drying circuit conventionally includes a fan F connected to a condensing duct C where the stream of moist air, coming from the tank through an air entrance A, flows in a direction opposite to the condensing water introduced in duct C through a relevant water entrance (not shown).
- a resistor R is arranged downstream from fan F in a return duct H to heat the air prior to returning it to tank T, while the water condensed in duct C is conveyed to the drain pump through a bottom drain.
- the washer/dryer is also provided with a load bay B where the user can load detergent and/or additives (e.g. softener) that are then taken to tank T by water jets W, controlled by an electrovalve, that wash away said products toward a connecting pipe (not shown).
- the load bay B is connected to tank T also through a vent pipe V usually located at the top of tank T.
- the novel aspect of the present invention is the presence of an expansion chamber E connected to the load bay B, and preferably adjacent thereto, as well as connected to the condensing duct C through a return pipe S.
- the above-mentioned electrovalve periodically re-activates the water jets W in bay B for some seconds, whereby the wetted walls are kept at a temperature lower that that of the moist air coming from tank T.
- the moist air after passing through bay B and releasing a portion of its moisture, proceeds to the expansion chamber E where it releases further moisture that condenses and flows down the return pipe S to the condensing duct C. Obviously, also the air proceeds along the return pipe S to the condensing duct C and joins the air coming from tank T through the relevant aperture A.
