Household-electric apparatus in order to wash and/or to dry being used the warm water of the circulating cetralized system in coils.
The invention regards the field deli employed household-electric apparatuses for the washing and/or I'asciugatura of pottery or biancheria.
In the aforesaid apparatuses they come executed several cycles of washing and/or drying, that they are controlled from a programmatore, and that they must employ nearly always water or air heated to a temperature prefissata.
Since thermal I'energia produced by means of remarkablly devout electric resistances and revealed expensive whom that produced by means of the burner of a system of cetralized heating, in the technique exists various apparatuses that, for the washing, capture cetralized I'acqua dalrimpianto of warm water, they stir and it by means of a mixer with cold water wishing quantity before sending it in the apparatus, generally on its bottom, waves to be able to execute the various types of cycle. II programmatore controls the operation of the mixer waves to obtain the temperatures indicated for the several ones cicli.
This type of various operation introduces pear tree at present inconvenienti.
II first of they and that racqua, once introduced in the household-electric apparatus, it is progressively cooled off to contact with I'apparecchio and the objects to wash or risciacquare, and consequently the cycle must have, for being effective, a rapportata duration alia medium temperature that avr& I'acqua during the same cycle, ragion for which such duration sar& remarkablly greater of that which would be demanded for a cycle during I'acqua conserved a temperature costante.
II according to given disadvantage and from the fact that, in the majority of the types of prewashing, as an example in the washing-machine, where such operation comes executed to a temperature of ca. 40°C, I'acqua, catching up the incrustations of sporco on the woven ones to that temperature, confers to the same sporco a resistance against the advanced removal to that which it would introduce if it came executed the prewashing to inferior temperature. An apparatus would be therefore useful that it could begin the prewashing to lowland temperature, and that it was then in a position to increasing with the intentional one gradualit& the temperature of the water as an example till the aforesaid ones ca. 40°C.
The washing-machine said wash-dries in particular, moreover, is not in a position to drying all the linen that can contain for the lavaggio.
This operation comes therefore of usual preferentially executed by means of an ulterior apparatus preplace exclusively to such scope, that it uses the heat produced from resistors inglobati within form elements opportuna.
II better of the result it would be that one of having a washing-machine that could modify the temperature of the water during its various cycles without to rerun alia expensive electric power, and that the linen washed without having could also proceed to the drying of all to extract it in all or partially dalrapparecchio, or of a clothes dryer that can dry the linen without having to resort electrically to the produced heat. In the event of the lavastoviglie the problems are similar, and would be opportune not to have to rerun to the use of the electric power in order to heat some racqua of in order to dry the stoviglie.
A solution to these problems and be dalI'inventore date by means of I'oggetto of the present question, cioe a household-electric apparatus correspondent to the state of the technique described in the preamboIo of attached rivendicazione 1, but characterized from exposed how much in the part characterizing of PCT No. PCT/EP94/04035 Sec. 371 Date Aug. 4, 1995 Sec. 102(e) Date Aug. 4, 1995 PCT Filed Dec. 2, 1994 PCT Pub. No. WO95/16066 PCT Pub. Date Jun. 15, 1995An electric domestic appliance (1) with programmer (5) for washing and/or drying dishes or laundry which uses in its cycles hot water from a central heating system introduced into its interior mixed by a mixer (2) with a predetermined quantity of cold water, and which also includes coil pipes (3) disposed in the vicinity of the section where the washing and/or drying takes place. Such pipes can be connected to the mixer (2) by a diverter (4) which, on command from the programmer, can divert the flow of water emerging from the mixer towards them or towards the interior of the appliance (1). The heat of the coil pipes can also be used to achieve drying via electric fans. 1. Household-electric apparatus (1) with programmatore (5) for the washing and/or rasciugatura of pottery or linen characterized from the fact that it uses in its cycles single the produced heat dalracqua warm of a system of cetralized heating introduced stirred its intemo or less by means of a mixer (2) with prefixed quantity of cold water, I'apparecchio comprising or pi0 disposed pipages to coil (3) in prossimit& of the zone where awiene the washing and/or I'asciugatura, collegabili to the saying mixer (2) for means of an organ shunter (4) place to go them of it, this last organ (4) being able to have the coming flow delracqua from the mixer (2) towards or pi0 of the said pipages to coil (3) or towards rinterno delrapparecchio (1) according to the commandos impartitigli from the programmatore saying (5). 2. Apparatus second rivendicazione 1, in which the said pipages to coil are at least in number of three, of the one (3a) nearly disposed one in the zone of rondo of the drying and/or washing space, and the others two (3, 3b) is arranged vertically on the two opposite flanks of the same space, rapparecchio (1) comprising also a pluralit& of elettroventilatori (6) with the Ioro air flows oriented so as to catch up the drying or washing zone after to have crossed the two at least said pipages to coil (3, 3b) decided vertically.
