Definitions

  • Electrical household appliance in particular iron, with a power consumer and with at least two plug contacts which can be contacted with associated contact pins formed in a socket for powering the iron, the socket being arranged on a base.
  • An electric iron from DE-34 36 901 Al is already known, which is equipped with two plug contacts which can be inserted into a socket and can be contacted with two contact pins.
  • the contact pins are shielded against unauthorized access from the outside by a pivotable cover.
  • the cover is normally in a closed position, so that the contact pins are only accessible if the shield is pressed down from the outside by putting on the iron. Since the cover can be actuated from the outside by the iron, there is also the possibility of pressing down the shield from the outside by means of a tool, so that access to the contacts is achieved without these being covered.
  • the result can be electric shocks on an operator's hand if he touches the live conductor with a current-carrying tool.
  • the invention has for its object to design and arrange the contact pins in a socket such that a voltage is applied to the contact pins only when all three contact pins are actuated simultaneously.
  • the contact pins are adjusted in their longitudinal axis by inserting the plug contacts into the socket such that at least one electrical switch associated with the contact pins or downstream is formed in the base and that one of the contact pins has an actuating element which only when inserting all plug contacts in the socket closes the electrical switches, thereby closing the circuit for the electricity consumer of the household appliance.
  • This ensures in a simple manner that people, if they touch the contact pins without permission, do not receive an electric shock because the contact pins do not carry any current according to the invention when the household appliance is not placed on the base.
  • the contact pins in the socket are arranged to be adjustable in the longitudinal direction against the force of a spring. This ensures that when the household appliance is removed from the base and thus when the plug contacts are removed from the socket, the contact pins are moved away from the switching elements of the electrical switches in accordance with the movement of the iron, so that these are opened and the contact pins are de-energized. This almost eliminates the risk of an accident.
  • the adjustment of the contact pins into their starting position is achieved by the spring elements arranged on the contact pins.
  • both contact pins can carry the current (positive pole), it is more advantageous for safety reasons if an electrical switch is assigned to each contact pin.
  • a voltage at the contact pins is therefore only present if all three contact pins are actuated simultaneously, that is to say that the actuating element can only be rotated about its longitudinal axis in an advantageous manner. If only the middle or the middle and an outer contact pin are adjusted in the direction of the two electrical switches, the actuating element comes to bear against at least one ramp formed on the external contact pins and is thereby rotated about its longitudinal axis to such an extent that when the contact pins are moved further, the actuating element switches the electrical switches no longer operated so that they remain in their open position.
  • the three contact pins in the socket are adjusted uniformly, so that the actuating element maintains the distance from the ramp and, as a result, the actuating element is not rotated after the plug contacts have been completely inserted, so that the electrical switches be brought into their closed position. An actuation of the electrical switch is only possible if all three contact pins are moved at the same time.
  • electrical contacts are provided in the region of the ends of the actuating element, which are in electrical contact with the contact pins and which form electrical switches with the contact pins.
  • This arrangement is particularly inexpensive to manufacture and requires few components. However, insulation must be provided from the transition of the electrical contacts to the control element.
  • control element arranged on the middle contact pin is T-shaped, that the control element consists of a web part and two leg parts running transversely to the web part, and that the web part can be brought into abutment against a spring bridge that switches the two electrical switches on and off.
  • an adjusting finger rises from the spring bridge parallel to the longitudinal axis of the contact pin and that the web part comes to rest on the adjusting finger when all three contact pins are adjusted in the direction of the electrical switch. So if one or two contact pins are adjusted, the actuating element, when it slides along the ramps, is pivoted by them, since, due to its guidance in the direction of movement, it can only evade the resistance of the ramp if it rotates. The actuating finger cannot move the electrical switch into a closed position, so that a high degree of security is obtained since an operator is not at risk from unintentionally touching two contact pins when the iron is removed.
  • the ramps run transversely to the longitudinal axis and obliquely downward in the direction of actuation of the contact pins and that the ramps run against each other and face each other.
  • an iron is denoted by 1, which can be placed on the socket 9 of a power supply device designed as a base 10 by means of a handle 3 arranged on the housing 2.
  • the base 10 itself can be connected to a wall socket via a cable (not shown in the drawing). After the iron 1 has reached the desired temperature, it can be removed from the base 10 and used for the ironing process.
  • the power supply of the heating device of the iron takes place via plug contacts 4 provided at the rear end of the iron 1, which are introduced into the socket 9 by placing the iron 1 on the base 10.
  • the socket 9 is arranged obliquely on the housing of the base 10, so that the iron more easily by hand on the housing 11 of the base 10 turned off and the plug contacts 4 can be safely and quickly inserted into the socket 9.
  • the switch-off device 28 formed in the socket 9 has three contact pins 7, 8 and 13 arranged next to one another, which are arranged axially displaceably in the guide shafts 5 provided in the socket 9 in guide elements 18 and which by means of the plug contacts 4 against springs 15 are adjustable.
  • the springs 15 are pushed onto the contact pins 7, 8, 13 and, when the iron 1 is removed from the socket 9, they move the contact pins 7, 8, 13 upwards until the contact pins come into contact with projections 14.
  • the projections 14 are formed in the guide elements 18 and prevent the contact pins 7, 8, 13 from moving out of the guide shafts 5.
  • an adjusting element 22 is rotatably arranged on the central contact pin 13.
  • the closing element 31 of the electrical switches 16, 36 are adjusted into a closed position by the adjusting element 22 or, according to FIG. 3, the electrical contacts 24 arranged on the adjusting element 22 become live Contacts 25 brought into power connection, so that the plug contacts 4 of the iron 1 are supplied with current.
  • the actuating element 22 which according to FIG. 5 is T-shaped.
  • the central web part 26 is arranged above an adjusting finger 34 arranged on a resiliently bendable spring bridge 30, while the legs 27, 29 of the adjusting element 22 are arranged laterally offset from the two electric switches 16 , so that they do not hinder the spring bridge 30.
  • the electrical switches 16, 36 shown in FIG. 4 can be used, for example, to avoid long distances on the contact pins 7, 8, 13 be designed as a microswitch.
  • the actuating element 22 is displaceably guided on a pin 19 formed on the contact pin 13 against the force of a spring 17. This serves to ensure that damping takes place when the actuating element 22 swings out on the spring bridge 30.
  • the actuating element 22 also moves downward according to FIG. 5 - without being rotated - until it rests on the actuating finger 34 and at 4, the spring bridge 30 bends downward (shown in dashed lines) until the normally open contacts 31 provided on the electric switches 16, 36 are adjusted, as a result of which the electric switches 16 are closed. In this way, the circuit is closed between the electrical switches 16, 36 and the external contact pins 7, 8 and current flows from them via the plug contacts 4 to the heating element of the iron 1, not shown in the drawing.
  • the middle plug contact 13 sets the zero Conductor and is therefore always connected to the neutral conductor of the energy source.
  • the contact elements 7, 8 are switched off when the iron 1 is removed from the socket 9 of the base 10 by means of the electrical switches 16, 36 from the power supply by the force of the spring 15 of the central contact pin 13 according to FIG. 4 is moved upwards, thereby lifting the web part 26 of the actuating element 22 from the actuating finger 34 and thus from the spring bridge 30 (FIG. 6). Likewise, the contact pins 7, 8 are brought into their starting position (FIG. 4) by the springs 15.
  • the switch-off device 28 shown schematically in FIG. 3 is essentially the same in operation as that in FIGS. 4 to 6 match, so that the same reference numerals have been chosen for the same components.
  • the main difference is only in that the actuating element 22 is electrically conductive and at the same time with the current-carrying contacts 25 and the contacts 24, the electrical switch, as shown in FIGS. 4 to 6 are designated 16 and 36, form.
  • the storage of the contacts 7, 8, 13 in the socket 9 can, as in FIGS. 4 to 6, be formed.
  • the contact pins 7, 8 are shown in FIGS. 3 to 6 can only be connected to the circuit if all contact pins 7, 8 and 13 are moved downwards together (see dashed operating position in Figures 4 and 6). If only one 7, 8 or 13 or two contact pins 7, 8 or 7, 13 or 8, 13 are moved in the direction of the electrical switches 16, 36, the actuating element 22 is shown in FIGS. 3 to 5 about a vertical axis 23 pivoted through the angle A when the central contact pin 13 is moved downwards. For this purpose, inclined and opposing ramps 20, 21 are attached to the two outer contact pins 8, against which the leg parts 27, 29 of the actuating element 22 come to rest.
  • leg part 27 or 29 naturally only comes into contact with the associated ramp 20 or 21 if the corresponding contact pin 7 or 8 is not moved into its dashed position (FIG. 4).
  • the leg part 29 lies against the ramp 21, i.e. So that the contact pin 8 has not been moved, the leg parts 27, 29 and in particular the web part 26 of the actuating element 22 inevitably rotate about the axis 23, so that the web part 26 comes out of the effective range of the actuating finger 34 and therefore with further displacement the spring bridge 30 and thus the electrical switches 16, 36 can no longer operate (FIG. 5).
