Definitions

  • the present invention concerns an automatic system for loading water into steam generating boilers.
  • the innovation is used particularly, if not exclusively, in the sector of appliances which use steam for carrying out their domestic or industrial functions, such as ironing systems, cleaning machines, pressure cleaners, extraction hydrojets, combined extractors, etc.
  • Another device is composed of a boiler with a tilted bottom on which an external heating plate is applied, said plate being made of die-cast aluminium and containing a resistance and thermostats for measuring the temperature.
  • the inconvenient aspects of this system are due to the fact that, as the water level falls, a part of the inclined bottom in contact with the heating plate is uncovered arid it becomes overheated due to the effect of the steam generating resistance, thus generating large quantities of scale in the wet-and-dry area with consequent loss of sensitivity of the system and rapid clogging due to scale.
  • One of the efficiency parameters for boilers or steam generators is the capacity to guarantee a constant amount of steam for as long a period as possible.
  • the efficiency of the steam production system also depends on the capacity of the loading system to keep the pressure level in the vaporisation chamber as constant as possible.
  • the aim of the present invention is also to overcome the above-mentioned inconveniences.
  • the vaporisation chamber has any shape, for example regular, parallelepiped, cylindrical or the shape requested and necessary for the appliance that uses the steam.
  • the duct or hole for filling the vaporisation chamber is situated on the roof of the chamber itself, near or vertically above the probe so that the filling water strikes the probe itself, or affects it as quickly as possible.
  • the probe is composed of a thermoconductive body, generally in the shape of a parallelepiped or a cylinder, with an end flange for fixing it onto the wall of the vaporisation chamber.
  • the probe thus composed, once it has been inserted, applied and fixed onto the wall of the vaporisation chamber, is inside said vaporisation chamber. Substantially, the lower edge of the probe will identify the minimum water level at which the vaporisation chamber must be filled, while the upper edge of the probe will identify the maximum level at which filling of the vaporisation chamber must be interrupted.
  • the probe thermostat is electrically connected to the pump that fills the vaporisation chamber.
  • the electric heating resistance of the probe heats the probe body itself, while the probe thermostat continuously controls the temperature of the probe itself.
  • the probe protrudes completely or partly from the water when the level of the water to be vaporised falls and consequently the heat generated by the heating resistance in the probe increases the temperature of the probe itself.
  • This increase in the probe temperature is detected by the thermostat which activates the pump, taking water from the tank and sending it into the vaporisation chamber. The added water strikes the probe and cools it.
  • the probe itself cools down when the water level has risen, reaching the lower limit temperature; at this point the thermostat commands the stopping of the filling pump.
  • the dimensions, the materials, and the thermal and thermoelectric characteristics of the various parts of the probe are studied and compared so as to have a high probe sensitivity. A very slight difference in level is obtained between the maximum level and the minimum level of the water in the vaporisation chamber.
  • the level gauge (2) by means of the acoustic indicator (or warning light) (3) notifies the user, who fills it with water; meanwhile the boiler will be heated by the main resistance (7).
  • the water in the boiler is at level (X) (see Fig. 2)
  • the pilot resistance (12) located in the control area (15) overheats the area, causing the intervention of the thermostat (13) which commands the motor pump (4) connected to the cold water tank (1) and to the boiler (6) by means of a pipe.
  • the entrance of cold water in the boiler (6) brings the water to the new level (Y).
  • the contact of the cold water with the control area (15) lowers its temperature, causing the opening of the thermostat (13) and the consequent stopping of the pump (4).
  • the main resistance (7) As it heats the water, the main resistance (7) generates steam which puts the boiler under pressure.
  • the pressure switch (9) intervenes and interrupts the power supply to the resistances.
  • the distribution of steam is accomplished by means of a solenoid valve (10) activated by a button (14) that controls the iron, floor washer or other machine, connected to it.
  • the consequent pressure drop causes intervention of the pressure switch (9) which again switches on the main resistance (7) to maintain the working pressure and the pilot resistance (12).
  • the consequent fall in the water level due to the distribution of steam again triggers the cycle for feeding water into the boiler as described above.
  • FIG. 4 shows an equivalent solution of the new boiler, while figures 5 and 6 show the two moments of low water level and high water level.
  • the cold water tank (1) is provided with a level gauge (2) which, by means of the acoustic indicator or warning light, notifies the user when there is no water.
  • the vaporisation chamber (6) heats the water that it contains by means of the main resistance (7). At the same time the resistance (12.2) of the probe (12) heats the body (12.1) of the probe (12) itself and the heat is absorbed by the water in the vaporisation chamber (6).
  • the pressure switch (9) intervenes and interrupts the power supply to the resistances (7, 12.2).
  • the distribution of steam is accomplished by means of a solenoid valve (10) activated by a button that controls the appliance that uses the steam.
  • the consequent pressure drop causes intervention of the pressure switch (9) which again switches on the main resistance (7) to maintain the working pressure and the resistance (12.2) of the probe (12).
  • the pump (4) takes water from the tank (1) and sends it into the vaporisation chamber (6) through a filling nozzle or hole (8), in such a way that the water strikes or in some way washes against the probe (12).
  • This system allows frequent brief cold water loading operations so as not to jeopardise the pressure that has formed inside the boiler.
  • the traditional pressure switch detects the pressure (with a much smaller delta) and is then activated only in the cases where work is finished, thus avoiding interventions of the pressure switch which switches off the main water heating resistance during the loading phase and therefore allowing continuous and efficient work.
