Clothes drying machine with improved vapour injecton arrangement

Abstract

Household- type clothes drying machine provided with a rotating drum (1), first means adapted to circulate a stream of drying air through said drum and comprising an appropriate inflow conduit and an outflow conduit for said air stream, second means (3) adapted to generate a gas or vapour stream, a first delivery pipe conduit (4) connecting said second means with an ejection arrangement located on the inner surface of the loading door of the drum, a second drain pipe conduit (7) adapted to collect the condensed moisture from said ejection arrangement and convey it into a collecting container; said ejection arrangement comprises a substantially sealed cell that is however provided with a first port (9) to enable the gas / vapour stream to flow in from said first delivery pipe conduit, a second port (10) to enable liquid and condensate to flow into said drain pipe conduit, and an ejection window (11) that opens into the interior of said drum and is adapted to eject said gas / vapour stream flowing in from said first delivery pipe conduit. Inside said cell there is provided a vertically extending wall and said first port is oriented towards said wall, which terminates with a free lower, edge projecting onto the bottom of said cell.

Description

technical field [0001] The present invention relates to an improved laundry dryer, preferably of the domestic type, adapted to perform an operating cycle for treating laundry loaded in the dryer drum by allowing a fluid This is performed by the entry of a medium, such as in particular a gas, or more in particular steam (ie water vapour), or steam entrained and mixed with particles of condensed water, into the drum containing the laundry. Background technique [0002] In the following description, although reference is made primarily to steam jets when talking about said fluid or medium, since said fluid or medium is to be sprayed into the laundry containing drum, this should in all cases be understood as meaning: Said medium may be any fluid mixture, advantageously in gaseous state, containing any number of other substances, such as detergents, fragrances, disinfectants and the like. [0003] It is widely known for use on garments and clothing in general, but also on the mo...

[0012] 2) The second disadvantage arises from the fact that since the treatment is usually carried out after the drying cycle, or is a separate program carried out independently, it cannot be followed by any other treatment, it may happen that the normal The liquid particles of treated clothes tend to remain on the clothes and at the same time eventually dry out, however the liquid particles leave a clearly visible halo mark which tends to persist even after the clothes are removed from the drum; The end result is that the treated garments may end up being refurbished to look worse than the garments before they were treated for refurbishment, with notably small spots formed by the aforementioned droplets being clearly visible;

[0013] 3) A third disadvantage is related to the practical safety of using the dryer: the droplets coming out of the nozzles of the prior art may in fact even be after the treatment program has ended (i.e. opening the loading door of the dryer to allow the use of or puts his / her hand into the drum because the treated clothes are about to be removed from the drum), the dripping flow is maintained for a short period of time from the nozzle; in this case, due to the user's hand reaches below the nozzle so that the droplets fall and hit the user's hand, which certainly exposes the user's hand to a dangerous burn problem since the droplets are at a temperature of about 90°C
