Definitions

  • the invention refers to an improved type of laundry drying machine, preferably for domestic use, able of implementing refreshing and anti-wrinkling treatment for the laundry load.
  • Drying machines which are able of producing a kind of gaseous diffusion of liquid substances and to convey said substances into a drum containing laundry, with the purpose of carrying out a refreshing or anti-wrinkling treatment. Often the substance used for the treatment is simply steam.
  • the condensed moisture generated by said drying and condensation process is used to transform it again into a steam flow, or simply into a diffusion of atomized moisture using ultrasound techniques, to be diffused through said laundry load to obtain the wanted effect of refreshing and anti-wrinkling.
  • the water which is needed is supplied by a standard container, e.g. a bottle, and is soon properly filtered by a "filter vent" whose purpose is to intercept out of that water the there included the residual material possible therein included.
  • the aim of the present invention is therefore to solve the noted problem and thus providing a laundry condenser drying machine allowing the user to implement a refreshing and anti-wrinkling treatment on the laundry load, consisting, without activating a drying cycle, in the production of an over-heated steam flow, which is being mixed to an air flow which is made to circulate in the same drying-air conduit, and to let said air-flow to circulate, mixed with said over-heated steam, across the rotating drum with the laundry load, without suffering any risk that the nozzles injecting out said overheated steam be obstructed due to the lint accumulation, and without introducing again into circulation the same lint into the drying air conduit.
  • Figure 1 shows a schematic partial representation of the composition and of the connections of the hydraulic circuit of a laundry treatment machine according to the invention
  • Figure 2 shows a perspective view of the valve 18, partly in transparency, of a laundry treating machine as per figure 1 ,
  • Figure 3 shows, in a perspective exploded view, the valve of fig. 2
  • Fig. 4 shows a 'perspective view of the valve of fig. 2 completely closed and mounted in the final arrangement
  • FIGS 5 and 6 show respective schematic section views of the valve according to the invention, in two respective different working status.
  • a drying machine according to the prior art comprises a rotating drum, not shown, containing the drying laundry load, and which is crossed by an heated air flow; the moisture extracted from the laundry load during the drying process is being condensed by a proper condenser, and is collected by a collecting tray 12.
  • a pump 13 and a pipe 17 convey the condensate from the tray 12 to a main tank 14, which is removably associated to the machine and preferably placed in an upper region of the cabinet 2, so as to be easily extracted by the user.
  • a secondary tank 16 is provided to be in fluid communication with the condensate collection tray 12 by means of the pipe 17.
  • Valve means 18 control the condensate flows towards the main tank 14 and the secondary tank 16.
  • valve means 18 As it will be better understood later on, a specific embodiment and function of said valve means 18 will be the subject of the instant invention.
  • Pipe 17 branches in a plurality of conduits 19, 20 each of the reaching the respective tank 14, 16.
  • Secondary tank 16 is also hydraulically connected with a pipe 23 to an inlet opening steamgenerator 22 of know type, so that the liquor contained in tank 16 can be evaporated.
  • Steam produced by the generator 22 flows through a pipe 24 into the drum, or alternatively into the drying air conduit, not shown, for treating laundry.
  • valve means 18 When valve means 18 are in an open position, condensate liquor available in the tray 12 during or after a laundry drying operation is pumped by the pump 13 in the pipe 17 and divided between the principal tank 14 and the secondary tank 16. In this way a portion of the total amount of liquid extracted from laundry is saved in the secondary tank 16 and made available to be reused for a subsequent steam treatment.
  • valve means 18 When valve means 18 are in a closed position all the amount of condensate liquor pumped from the tray 12 is flowed into the principal tank 14 though a opening 25 that is placed at the pipe 19 outlet when the machine is in use. Said opening 25 serves also as overflow opening allowing the condensate.
  • said valve 18 is selectively controllable in its operation, not only in the sense that it may be opened or closed by an external command, but also in the sense that it contains a type of filter, which will be better described later on, whose introduction in the valve body determines the opening of the same valve, and inversely whose disengagement from the valve body determines its closing.
  • said valve 18 is substancially shaped as an outer cylindrical, internally hollow body, 21; to one of its ends said pipe 17 is connected, into which the condensate, coming from the tray 12, is flowing.
  • the actual filtering means 43 is lodged, which is made of a cylindrical element working as a support and a frame for a filtering septum 44 with very close mesh nets.
  • the working of said filter/valve 10 is as follows: when said filtering element 43 is being introduced into said hollow body 21 , the condensed water coming from the pipe 17 enters said same hollow body and the filtering element 43, which is closed on the opposite end. From the inside of said filtering element the condensed water, which may also be mixed with lint and foreign materials, filters trough the filtering septum 44, and gets out, flowing into the ring shaped inter-space between said septum and the inner surface of said hollow body.
  • said valve comprises said outer and hollow body 21 , and is internally provided with an annular relief 45, which is coaxial and internally opened with an opening 46.
  • said filtering element 43 is provided to its end, turned to said pipe 17, with a first extension 47 apt of crossing said opening 46 and to contact, by pressure, an essentially flat and closing member 48, placed between the affluent mouth 17-A of said pipe 17 and said annular relief 45.
  • said closing member 48 is provided towards said filtering element 43 with a corresponding and substantially coaxial and aligned second extension 48-A apt to engage said first extension 47.
  • a preferably spiral spring 50 is interposed between the inner end side of said hollow body 21 , towards said pipe 17, and the side 48-B, in front of it, of said closing member 48; said spring works on compression, and is preferably pre-loaded.
  • valve generally identified as 18, is being automatically closed by the simple extraction of the filtering element 43 out of said outer body 21 (Fig. 6).
  • a further improvement consists in the fact that said valve 18 is positioned in such a way that the filtering element 43 be directly accessible from the front machine, and that it can be extracted from, or engaged into said outer body 21 , through the simple rotation of a control element, as a rotating knob 54, placed outside the filtering element 43 itself.

Abstract

L'invention concerne une machine à sécher à usage domestique comprenant un tambour rotatif, un conduit de circulation d'air à travers ledit tambour, un condensateur d'humidité pour l'air séchant, un plateau (12) pour collecter l'humidité condensée, un moyen hydraulique capable d'aspirer l'eau contenue dans ledit plateau, et de la transporter dans un moyen de diffusion (22), même dans un état de vapeur, ou en tant que jet, directement dans ledit tambour, ou dans ledit conduit de circulation d'air. Ledit moyen hydraulique comprend un tuyau hydraulique (17), qui sort dudit plateau et finalement muni d'une pompe respective (13), et qui se raccorde (19), par l'intermédiaire d'une soupape à commande sélective (18), dans un réservoir secondaire (16) relié à un canal (23) et audit moyen de diffusion ou d'injection de vapeur ; ladite soupape (18) comprend un filtre (43) capable de filtrer l'écoulement de liquide qui le traverse. Ledit filtre peut être retiré et extrait du corps de soupape (21) ; lorsque ledit filtre est introduit dans ladite soupape, il laisse passer l'humidité, et lorsque ledit filtre est extrait de ladite soupape, l'accès d'entrée à ladite soupape reste fermé.
