Definitions

  • the invention relates to a combined steam cleaning and steam ironing device with a steam generator, in which a water supply is evaporated by an electric heater, and with a connection to the steam generator, to which steam dispensing devices or an iron can be connected, via which the steam generator Connection and a steam line steam can be supplied.
  • Steam cleaning devices of this type are known which can be operated with different accessories, for example with point jet nozzles, with wiping heads, with brushes or with wiping lips, but also with an iron which is made into a steam iron by the steam supply.
  • the steam iron While no electrical supply of the steam delivery device is necessary for the other accessories, the steam iron is heated by an electrical heater built into it, and this requires an electrical supply to the steam iron, which is usually provided by the steam generator, which in turn is also electrical is heated trically.
  • the Water heating must always be dimensioned so that the maximum value of the power that can be drawn from the mains is not exceeded during ironing. This limits the evaporation capacity of the steam generator.
  • This object is achieved according to the invention in a combined steam cleaning and steam ironing device of the type described at the outset in that when an iron is connected, the power of the heating evaporating the water supply is inevitably reduced compared to the power when the other steam delivery devices are connected, and at the same time an electrical connection between the steamers ⁇ generator and iron is produced, via which an electric heater in the iron is supplied.
  • the heating in the steam generator is such that when the steam delivery devices themselves, which do not require any electrical energy, they operate at a higher power than when connecting one Iron.
  • the electrical power made available by the supply network can be fully utilized.
  • the electric heater in the steam generator comprises two heating elements, one of which is switched off when an iron is connected to the Steam generator is connected.
  • the heating power of the steam generator is thus reduced only when an iron is connected, but in all other phases, ie when one of the other steam delivery devices is connected or when there is no connection, the electric heating in the steam generator is operated at full power.
  • the electric heater in the steam generator comprises two heating elements which are only switched on together when one of the other steam delivery devices is connected to the steam generator.
  • connection comprises a plug and a socket with a plurality of electrical contacts which on the one hand are so differently used in the iron and on the other hand in the other steam dispensing devices that the heating in the steam generator is connected only when the iron is connected works with reduced power.
  • switch the power consumption of the heating in the steam generator with a wide variety of means Chen, for example by mechanically actuated contacts during the production of the connection
  • an electrical solution is proposed here, in which the electrical connections are switched so that the power of the heating is automatically switched by the production of the contact, that is to say the production of the plug connection is varied in the steam generator according to the connected accessory.
  • connection has further electrical contacts through which a control line, which can be activated on the steam delivery device or on the iron, leads to switching elements in the steam generator. You can then control functions in the steam generator, for example the steam supply, on the steam delivery device or on the iron.
  • the iron and the other steam delivery devices occupy different electrical contacts for the control line in the connection, so that different switching elements in the steam generator can be actuated.
  • the switching element which can be actuated by the control line in the steam generator can be a closing valve with steam quantity regulation in the iron, whereas a closing valve without steam quantity regulation can be used in the other steam delivery devices.
  • the steam line is also integrated into the connection comprising a plug and a socket.
  • the connection comprising a plug and a socket.
  • Figure 1 is a view of a steam generator with a connected accessory and an optionally connectable steam iron
  • FIG. 2 a schematic circuit diagram of the electrical parts in the steam generator
  • Figure 3 is a schematic view of the electrical connection part of the iron and
  • Figure 4 a view similar to Figure 3 for an accessory without electrical consumers.
  • a steam generator 2 is accommodated, which comprises a water tank (not specifically shown in the drawing) and an electric heater that evaporates the water in the water tank.
  • the steam generator 2 has a connection 3 in the form of a socket 4, to which a plug 5 can be connected, which is connected via a line 6 to a steam delivery device, in the example shown with a wiper head 7.
  • This wiper head could also be through a jet pipe or any other device can be replaced by which steam should be given, there are usually several steam delivery devices that can optionally be connected to port 3.
  • An iron 8 which also has a line 6 and a plug 5, can also be connected to the steam generator 2.
  • Plug 5 and socket 4 contain a connection possibility of a steam line, on the other hand they have a number of electrical contacts through which several parallel electrical connections can be made. In the following it is assumed that six such electrical contacts are available, of course any other number is also possible.
  • the steam generator 2 is connected to a voltage source via an external electrical supply line, this line is not shown in FIG. 1.
  • this line is not shown in FIG. 1.
  • the two branches 9, 10 of the supply line are identified with the letters L and N.
  • the branches 9 and 10 are connected to the ends of a heating element 12 via a two-pole switch 11, which ches the water storage tank in the steam generator 2 heated and thus evaporates water.
  • a second heating element 13 is connected in parallel to the heating element 12, but its supply line leads to the contacts D and E of the socket 4 and is interrupted there.
  • the heating element 13, which also heats the water reservoir, is only activated when this interruption between the contacts D and E is closed.
  • the two heating elements 12 and 13 thus together form the evaporator heater, but they are not necessarily always activated together.
  • the contacts E and F are connected to one another via a heating element 14, this heating element 14 is located in the iron 8.
  • the contacts E and F of the steam generator result 2 a connection of the contacts E and F of the plug to the two branches 9 and 10 of the voltage source, since the contact F of the socket 4 is connected to the branch 9 of the supply line via a line 15 and an accessory switch 16, the contact E is direct with the branch 10 connected to the supply line. This results in heating of the iron as soon as the connection is established.
  • the power of the heating element 14 corresponds to that of the heating element 13, it is then possible overall to always utilize the power optimally made available by the network, be it for vaporizing strongly in the steam generator when operating an accessory without electrical Supply or be it with evaporation with reduced power and simultaneous heating of the iron.
  • the branches 9, 10 of the supply line are connected via the accessory switch 16 to a voltage converter 17, the secondary side of which is connected on the one hand to the contact A and on the other hand via two parallel lines 18, 19 to the contacts C and B of the socket 4 in Connection is established.
  • a solenoid valve 20 is inserted in line 18, which opens when the current flows and is otherwise closed, in line 19 a solenoid valve 21 with a metering device, which also opens when the current flows and is otherwise closed.
  • the solenoid valve 21 can be metered, for example, by means of a rotary knob 22 on the upper side of the steam generator 2 (FIG. 1).
  • contacts A and B are connected to one another via a pressure switch 23, so that this connection can be established when the pressure switch is actuated.
  • the solenoid valve By actuating the pressure switch 23 the solenoid valve is opened with metering, steam then flows to the iron with the amount set on the rotary knob 22.
  • the contacts A and C are connected to one another via a pressure switch 24 connected, this also closes the connection when actuated. From these devices, the solenoid valve 20 can thus be opened by actuating the pressure switch 24, so that steam is then supplied in full to the steam delivery device.
  • Contact C is not used for the iron, but contact B is not used for the other steam delivery devices.

Abstract

L'invention concerne un appareil combiné de nettoyage et de repassage à la vapeur, comportant un générateur de vapeur dans lequel une réserve d'eau est vaporisée par un élément de chauffage électrique. Cet appareil comporte en outre un raccord à un générateur de vapeur, auquel peuvent être raccordés soit des dispositifs d'émission de vapeur soit un fer à repasser, ces équipements pouvant être alimentés en vapeur au moyen du raccord et d'une conduite de vapeur. L'invention vise à assurer un chauffage optimal du générateur de vapeur. A cet effet, lors du raccordement d'un fer à repasser (8), la puissance du chauffage (12, 13) assurant la vaporisation de la réserve d'eau est nécessairement réduite par rapport à la puissance requise lors du raccordement des autres dispositifs d'émission de vapeur (7). De plus, une liaison électrique entre le générateur de vapeur (2) et le fer à repasser (8) permet d'alimenter un élément de chauffage électrique (14) dans le fer à repasser (8).
