Definitions

  • the present invention relates to a steam generator intended to be associated with irons, steam-cleaning equipment, coffee-producing machines, saunas or the like.
  • the invention relates to a steam generator consisting of a tank for the water, connected to a boiler by a pipe which has inserted inside it an electric delivery pump which controls the water supply from the tank to the boiler, when necessary.
  • the boiler comprises, moreover, electric heating means.
  • the boiler has inside it an electric coil immersed in the water to be heated.
  • This coil has associated with it, moreover, a thermostatic switch which controls the supply of new water when the level falls below a predetermined minimum value.
  • a further disadvantage of this known solution is due to the well-known formation of scale on the coil which alters the technical characteristics thereof, resulting in it becoming unusable with the passing of time.
  • a solution is also known in which the electric coil is replaced by two heating plates located inside the boiler, one in the vertical position and the other in the horizontal position. This solution, however, is unable to overcome the drawbacks mentioned above since these plates are also subject not only to the phenomenon of deposition of the calcium present in the water, but also to the action of thermal shock.
  • a steam generator comprising a boiler consisting of a long vertical tube, in which the electric heating means consist of an electric spiral applied to the outside of the boiler by means of welding.
  • a steam generator comprising a boiler with a pressure switch and thermostats, which is connected to an iron, and a separate top-up tank for the water connected via a pump to the boiler.
  • the pump activation means consist (in accordance with a preferred solution of the invention) of a temperature detector formed by a heat transducer associated with a heating means and a thermostatic switch connected to the heat transducer.
  • An object of the present invention is therefore that of overcoming the said drawbacks displayed by the devices of the known type, by providing a steam generator for irons or the like, which, reduces the times for heating of the new cold water added into the boiler during use so as not to create any interruption in the supply of steam.
  • a further object achieved is that of making the best possible use of the little space which is available inside irons or the like by providing a generator which is able to supply, within a short time after switching-on, an abundant continuous supply of steam.
  • Another object is that of providing a steam generator which, in addition to its functional nature, is also economical in terms of production and operation thereof.
  • an object is that of speeding up the reaction times of the thermostatic switch, limiting at the same time the thermal fluctuations of the heating plate.
  • a further object of the present invention is that preventing, during the normal conditions of use of the generator, that the latter is able to supply, together with the steam, also water which is not yet evaporated.
  • Another object of the present generator is that of limiting the formation of solid residue inside the boiler.
  • an object of the invention is that of configuring the boiler so that the generation of steam is never interrupted even when, during particularly critical operating conditions, the supply of new cold water should occur with a certain delay.
  • a boiler with an inclined bottom onto which the heating plate is externally mounted there is provided a thermostatic switch which controls the supply of new cold water to the boiler is mounted in a top zone of the plate.
  • the hole via which the water enters is arranged in the region of the zone where the thermostatic switch is mounted, so as to obtain the double advantage of heating the water very rapidly, bringing it into direct contact with the superheated surface of the boiler which is located above the water level, and cooling equally rapidly the heating plate so as to rapidly enable the command regulating the supply of new water.
  • the generator is extremely sensitive to the temperature variations and is able to provide steam at a constantly high pressure.
  • 1 denotes schematically in its entirety a steam generator intended to be associated for example with a steam iron 8 or a steam cleaning apparatus or else a coffee-producing machine or similar equipment.
  • the generator 1 which is usually arranged inside a casing not shown, comprises a water tank 2 provided at the top with a filling plug 19, and a boiler 3 for generating steam under pressure, connected to the tank 2 via a water supply pipe 5 which contains a delivery pump 6, normally an electromagnetic pump or equivalent type.
  • the tank 2 and the boiler 3 are also connected together via a flowback pipe 20 which has associated with it, in a manner known per se, an overpressure valve 21.
  • a non-return valve 9 communicating with the tank 2 via a return pipe 24.
  • the bottom 11 of the boiler 3 has an inclined zone 14, as can be clearly seen from Figure 1.
  • the boiler 3 is provided with electric heating means 4 associated therewith. These comprise a heating plate 18 mounted externally and connected in a close-fitting manner to the boiler 3 itself in order to optimize transmission of the heat in both directions, from the plate 18 to the water and vice versa. This connection may be achieved for example, in practice, by means of bolting with the application, in between, of a thermally conductive paste (not shown).
  • the inclined bottom 11 has two portions, a lower portion 12 and an upper portion 13, one being arranged at the lowest point inside the boiler 3 and the other in the vicinity of the highest internal zone which is still in contact with the heating plate 4.
  • the heating plate 4, which is single, extends substantially over the entire bottom 11 and has mounted on it a thermostatic sensor located in the region of the upper portion 13.
  • This thermostatic switch 16 interrupts the electric power supply when the heating plate 18 reaches or exceeds a preset operating temperature and reactivates it as soon as the temperature falls back below this limit.
  • the bottom 11 which is thus inclined has a considerable heating surface area which comes into contact with the water, certainly greater than that of an ordinary flat bottom.
  • the boiler 3 has an opening 15 formed substantially along the vertical of the thermostatic switch 16 and connected to the water supply pipe 5.
  • the single thermostatic switch 16 present is of the bivalent type; it is in fact able to control two different operating temperatures. The first is the one detected when the water, evaporating, partially frees the surface of the upper portion 13, causing its temperature to increase. The second temperature level which the thermostatic switch 16 is able to detect is the limit temperature which the heating plate 18 should never exceed. It therefore consists of a safety temperature beyond which the thermostatic switch 16 intervenes, interrupting the electric power supply to the plate 18, whatever the operating condition of the generator 1 in that given instant.
  • the thermostatic switch 16 therefore acts as a detector of the level of the water inside the boiler. In fact, when the water level falls, freeing partially the upper portion 13, the latter is surrounded by steam. Owing to the altered heat exchange coefficient, which is drastically worsened, the temperature of the plate 18 rises rapidly and this rise in temperature causes tripping of the thermostatic switch 16.
  • the boiler 3 moreover has connected to it a steam delivery pipe 7 which terminates in the iron 8 and which has inserted inside it a steam valve 10 which can be operated so as to cause steam 8 to flow out towards the iron 8 whenever necessary.
  • the boiler 8 has, moreover, a discharge plug 23 arranged in the vicinity of the lower portion 12 for removal therefrom of the scale which inevitably forms inside it with time.
  • FIG. 2 shows a constructional variant of the boiler 3'.
  • the inclined bottom is replaced by a flat bottom from which there rises an upper portion 13' formed in the manner of an upturned "U".
  • the heating plate 18' is shaped so as to match exactly the shape of the bottom of the boiler so as to heat the entire surface of the bottom itself.
  • 16' denotes the thermostatic switch arranged, in this case also, in the region of the upper portion 13'.
  • the heating plate 18,18' is supplied electrically by control means (not shown since they form part of the known art), independently of the presence or otherwise of water inside the boiler 3,3'. At this point there are 3 extreme situations:
  • the temperature rapidly increases since there is no water to be heated and trips the thermostatic switch 16 which causes entry of the water via the opening 15 by operating the pump 6.
  • the water falls directly onto the upper portion 13,13' which is very hot and rapidly heats, cooling at the same time the zone controlled by the thermostatic switch 16.
  • the latter then trips again causing switching-off of the delivery pump 6. This operation is automatically repeated several times until the water level is brought up to a preset level.
  • the thermostatic switch 16 causes this automatic operation as a result also of its well-known feature of opening the contacts at one temperature, but closing them again at a slightly different temperature.
  • the intervention time of the thermostatic switch 16 becomes slightly longer since the thermal energy produced by the plate 18 is first of all absorbed by the water. As soon as the level of the water falls below the upper portion 13,13', the thermostatic switch 16 intervenes in the manner already described.
  • This constructional feature moreover prevents the temperature of the boiler from remaining for long periods of time at very high values. This has a positive effect on the quantity of calcium which is deposited inside the boiler, reducing, as is well known, this calcareous formation with a reduction in the temperature.
