Definitions

  • This invention relates to a steam generator for domestic use designed, for example, for cleaning tasks, in which the steam production boiler is separate from the water supply tank; the said generator is fitted with systems which constantly monitor the water level in the boiler and top it up continually during operation, drawing small amounts of water from the tank in order to keep the level approximately constant during use.
  • this appliance is far more practical and convenient to use than the current ones.
  • the appliance in accordance with the invention which falls into the category of household cleaning appliances, is also much safer, because it is hardly ever necessary to open the boiler or operate parts which may be at a high temperature and pressure.
  • the boiler also constitutes the water storage tank.
  • This type of appliance therefore requires some caution on the part of users, and consequently presents a degree of risk if used by inexpert or imprudent persons.
  • no. 1 indicates the body of the appliance, which is mounted on wheels 2 and fitted with a connector 3 for a steam outlet pipe.
  • Body 1 houses steam production boiler 4 connected to a tank 5, closed by a cap 6, which is accessible from the outside of the appliance.
  • Boiler outlet 10 leads to a solenoid valve 11 which opens and closes the connection between the boiler and a pipe 31, leading to the union of outlet 3.
  • a pressure switch 12 a connector 13 for a pressure gauge 32, and a flow rate regulation tap are fitted on the pipe which connects the boiler to the solenoid valve.
  • the water in the boiler is heated by a resistor 15, the power supply to which is controlled in a known manner by pressure switch 12 and a pair of thermostats 13 and 14.
  • Thermostat 13 detects the temperature in the boiler and acts as safety switch in the event of malfunction of pressure switch 12, while thermostat 14 detects the resistor temperature, and comes into operation if the resistor is powered while the boiler is empty.
  • the pressure switch also controls the switching on and off of a warning lamp on the casing of the appliance, not illustrated in the figure, which indicates when it is ready for use.
  • Pressure switch 12 also includes a safety valve which discharges water directly into tank 5 through a pipe not illustrated in the figure in the event of excess pressure.
  • the power circuit of resistor 15 also includes a diode 17, activated by a microswitch 30, which monitors and limits the power supply to the resistor.
  • a sensor of known type which monitors the water level in the boiler is also fitted to boiler 4.
  • Sensor 19 is connected to an SCR diode 20 which powers the drive motor of pump 8.
  • the SCR diode activates the motor of the pump, which draws a small amount of water from tank 5 through catalytic filter 7 and introduces it into the boiler.
  • the appliance is fitted with systems which warn when the water level in tank 5 is approaching the minimum and shut down the machine before the water runs out.
  • the tank contains a float 21 with a built-in magnetic element whose presence is sensed by a Hall probe fixed to the body of tank 5 and also connected to the SCR diode.
  • the appliance operates as follows: Assuming that the water in boiler 4 is already at the level set, the machine is switched on and powers electrical resistor 15 which heats the water until the required temperature is reached, when pressure switch 12 cuts off the power supply.
  • the pressure switch deactivates the warning light on the control panel, indicating that the appliance is ready for use.
  • the SCR diode then activates the motor of pump 8 which draws water from tank 5 through catalytic filter 7 and pumps it into boiler 4 until the original level is restored.
  • the appliance can be operated at low power by activating diode 17 which limits the amount of current sent to resistor 15.
  • the boiler can contain a small amount of water (approx. 500-800 cc), which reduces the initial heating time.
  • the steam generator in accordance with the invention could also be used to manufacture various appliances such as irons, sterilisers, humidifiers, dishwashers, inhalers, etc., while still remaining within the ambit of the invention.
