Definitions

  • Present invention refers to a washing and drying machine, comprising a circuit for air circulation, means for heating said air, means for conveying the heated air into the laundry basket and a system for condensing the moisture extracted from the laundry.
  • Machines of the described type are normally in use to wash and dry household laundry.
  • the damp air is sucked out of the basket by a centrifugal fan, heated and dried by means of electrical resistors, conveyed again into the basket so as to act on the laundry, and so on.
  • the air is conveyed into the basket through a suitable outlet, located near the porthole; the sucked damp air is conveyed into a condensing chamber, where it passes through a water rain so promoting the condensing of the moisture.
  • non-washing machines wherein the air is conveyed into the basket through the rear wall thereof, by means of holes suitably located round the hub; it is important to point out that such non-washing driers shall not withstand the spinning stress, therefore they need much lighter and thinner hubs.
  • Front loading washing and drying machines of the described type show inconveniences, like the following: - loading the laundry through the porthole is uncomfortable; - the air conveyed into the basket gets partly lost through the gap between basket and bellows and also because it is sucked before acting onto the laundry; - heated air hits the glass of the porthole; the relevant heat gets therefore lost as far as the laundry drying is concerned.
  • the subject of present invention is a washing and drying machine, comprising a circuit for air circulation, means for heating said air, means for conveying the heated air into the laundry basket and a system for condensing the moisture extracted from the laundry, characterized in that the machine provides for a top loading system for the laundry.
  • the machine according to the invention is characterized in that said means for conveying the heated air into the laundry basket are so realized that the inlet of the air into the basket takes place through a hub of the basket, which is axially hollow.
  • reference number 1 indicates the basket of the washing and drying machine; said basket is fastened to bearing 20, which in turn is screwed to rear hub 18; front hub is not shown in the figure for the sake of compactness; as the washing and drying machine provides for top loading the customary porthole on the front is not present.
  • Damp air is sucked from basket 2 and passes, through a filter 17, into small chamber 3, which is a part of condensing chamber.
  • Small chamber 3 is divided from small chamber 5 by means of a baffle 4, which estends for a good part of the condensing chamber (see fig. 3); baffle 4 forces the air to a U shaped path to pass into small chamber 5, wherefrom it is sucked into small chamber 6, where there is located a centrifugal fan, not shown in the figure and driven by the electric motor 8.
  • the dried air is forced into a duct, made by two pieces 10 and 12; such a duct may also be made by only one piece as well as by many pieces, according to specific manufacturing or economic problems.
  • a duct made by two pieces 10 and 12; such a duct may also be made by only one piece as well as by many pieces, according to specific manufacturing or economic problems.
  • electric heating resistors 13 which heat and dry it, and then arrives again into basket 1 through the hollow rear hub 18; entering the basket the air passes trough a filter 16, similar to filter 17.
  • the main fixed part 10 of the duct may be made of zamak die-casting or the like, or out of metal sheet; besides resistors 13 are fastened to part 12; in this way also duct 10 heats up so contributing to air heating and drying.
  • the lid 12 of the duct is also made out of metal sheet or by die-­casting, e.g. an aluminium alloy, and is fastened to fixed part 10 by means of small springs 11 and 14.
  • Filter 16 may be made out of metal sheet or plastic material, while for the sake of inexpensiveness and ease of manufacturing they may be obtained by means of 2 mm dia round holes or different shaped holes, made in such a number that the free area represents about the 35% of the total area (measured as if it were full).
  • air inlet in the basket is perfectly central; as a consequence the effect on the laundry of the heated and dried air is optimized, in that the laundry, owing to basket motion, tends to open centrally shifting towards basket walls, leaving free entry for the air and lending to very good uniformity of drying.
  • the condensing chamber is for a great part made enblock with the tank of the machine; lid 7 with motor 8 is attached by means of small springs, one of them being shown at 9.
  • the fan located inside chamber 6, being far from heating resistors 13, may be advantageously made out of plastic material, so greatly reducing manufacturing costs.
  • resistors 13 are nearer, in respect of known machines, to the entry point of the heated air into the basket, so reducing the amount of heat which is lost by dispersion; indeed the distance between the resistors and the entry point is, in the machine according to the invention, less than 30 cm, in comparison of 60 cm in the known machines.
  • figure 2 which shows a cross section, at right angle to the previous one, expounding the condensing chamber of the machine according to the invention, the elements bear the same reference numbers as in fig. 1; reference number 19 indicates the moisture collecting sump, taking in account that the horizontal axis here is rotated clockwise of 30°.
  • Reference number 27 indicates the top opening of the tank, wherethrough the laundry to be washed and dried is loaded.
  • figure 3 which shows a third cross section of the condensing chamber of the machine according to the invention, there is clearly shown the effect of the separating baffle 4 on the air path, indicated by arrow 28.
  • Condensing walls are obtained respectively from a piece of the tank, wall 29, and an additional wall 30, preferably made out of rustless metal.
  • Metal wall 30 has the purpose of promoting the condensing process, on both sides, because it dissipates the heat better.
