Definitions

  • the invention relates to a device for controlling at least two indicator lights for status indication mounted on a household appliance fitted with an adjustable thermostat with quick opening by shifting from neutral, comprising an insulating support receiving an arm of the thermostat, a blade forming a fixed contact, a movable blade provided with a flexible tongue on which an insulating pin presses, controlled by a rotary screw making it possible to obtain a set temperature, and another movable blade fixed to the movable blade and the free end of which carries a fixed contact, as well as an insulating spacer integral with the bimetallic strip and controlling the movable blades, the blade forming fixed contact and the movable blades being fixed to the insulating support, connected respectively to electrical terminals by electrical connections and supplying the two indicator lights luminous.
  • control devices use electronic devices for processing information from a quick-opening thermostat and controlling triggering indicator lights. These electronic devices are sensitive to variations in temperature and humidity. In addition, the insertion of such electronic devices considerably increases the cost price of a household electrical appliance.
  • the object of the invention is to remedy the aforementioned drawbacks by implementing a device for controlling the indicator lights which is mechanical, simple and economical.
  • the device for controlling at least two status indication lights mounted on a household appliance comprises an elastic conductive strip having a free end and one end fixed to the insulating support, electrically connected by this end to the terminal and engaged with the flexible tongue by a support means, and a conductive element fixed on the insulating spacer, connected by an electrical connection to one of the two indicator lights and capable of coming into contact with the free end of the conductive strip when the heating temperature is higher than the set temperature.
  • control device Thanks to the control device according to the invention, the electronic devices are eliminated and a limitation is therefore obtained on the number of electrical components inside the household appliance which reduces the cost of said appliance.
  • simplicity of said device increases the free space inside the household appliance improving the possibilities of arrangement of the numerous elements contained inside the household appliance.
  • an adjustable type thermostat 1 provided with a quick-opening device 2 of known type equips an electrical household appliance, for example an iron F, a part of which corresponding only to the heating soleplate is shown.
  • a circuit for supplying an electrical resistance R heating the soleplate of the iron comprises electrical lines 3 and 4 connected to a socket 5 intended to be connected to an electrical distribution network.
  • Said supply circuit operates with the quick-opening device 2 which is moved by the bending of a bimetallic strip 6 capable of transmitting a displacement to two movable blades 7 and 8 via an insulating pin 9 interposed between a end of the bimetallic strip 6 and the ends of each of the mobile blades 7 and 8.
  • the mobile blade 7 is fixed by one of its ends in contact with an electrical terminal 19 and the other end of which is fixed to the mobile blade 8 the free end of which carries a contact capable of bearing on a blade 16 forming a fixed contact.
  • the movable blade 7 is provided with a flexible tongue 20 produced, for example, by cutting on said blade 7 and on which an insulating dowel 22 is supported, controlled by a rotary screw 10 making it possible to obtain a set temperature.
  • the thermostat 1 also includes an insulating support consisting of three elements 13, 14 and 15 receiving a thermostat arm 11 fixed by a screw 12 and the blade 16 forming a fixed contact.
  • the insulating support by its elements 13, 14 and 15 maintains electrical terminals 18 and 19 connected respectively to the electrical lines 3 and 4.
  • the blade 16 forming a fixed contact has one end 25 pressed against one end 26 of the terminal 18, the ends 25 and 26 being positioned between the elements 14 and 15 of the insulating support.
  • the other end 27 of the terminal 18 is connected by an electrical connection 28 to a first tab 29 of an indicator 30 and to one end 31 of the resistor R, the other end 32 of the resistor R being connected to the line electrical 3 of the socket 5.
  • the second tab 33 of the indicator light 30 is connected to a terminal 34 of a resistor 35, the other terminal 36 of the resistor 35 being connected to the electrical line 3.
  • a terminal 37 of another resistor 38 is also connected to the power line 3.
  • the other terminal 39 of the resistor 38 is connected to a lug 40 of another indicator 41, the other lug 42 of the indicator 41 being connected to a terminal 43.
  • Said terminal 43 is fixed by a conductive element 44, for example a rivet, to a boss 45 of the insulating plug 9.
  • the boss 45 is in connection with the central part of the insulating plug 9, each of the ends of which is connected respectively to the bimetallic strip 6 and with movable blades 7 and 8.
  • the rivet 44 presents te, for example, a frustoconical end 46 opposite which is positioned, at a determined distance, one end 47 of an elastic conductive strip 48.
  • the other end 49 of said strip 48 is pressed against the terminal 19, so that the terminal 19, the end of the movable blade 7 and the end of the blade 48 are positioned between the elements 14 and 13 of the insulating support.
  • the elastic conductive strip 48 is, for example, a metal strip having a hole 50 through which passes the insulating plug 22. Said metal strip 48 rests on the flexible tongue 20 by a support means 51. Said support means is , for example, a lug 51 produced by a cut in said blade 48.
  • the conductive blade 48 has, for example, a coefficient of stiffness less than the flexible tongue 20.
  • this set temperature corresponds to the ironing of a particular type of garment.
  • the soleplate of the iron heats up, the indicator light 30, for example of a green color, lights up since the contact between the end of the blade 16 forming fixed contact and the free end of the movable blade 8 is closed. Then, during the desired rise in temperature, the free end of the bimetallic strip 6 bends upwards and tends to raise the end of the movable blades 7 and 8.
  • the movable blade 8 When the neutral point is exceeded: the movable blade 8 suddenly leaves the blade forming a fixed contact 16 to abut against a fixed point 23 of the movable blade 7 and the indicator light 30, for example designated as a heating indicator, goes out; the flexible tongue 20 of the movable blade 7 pushes on the lug 51 of the metal blade 48 and separates said blade 48 from the end 46 of the rivet 44.
  • the user When the user desires a temperature lower than the temperature previously requested, the user rotates the rotary screw 10 of the thermostat 2 in the opposite direction so that the contact between the end of the blade 16 and the free end of the movable blade 8 comes to open.
  • the insulating plug 22 therefore presses on the flexible tongue 20 and pushes it in, the lug 51 is thus released.
  • the end 47 of the metal blade 48 comes into contact with the end 46 of the rivet 44.
  • This contact triggers the lighting of the indicator light 41, for example of red color, which indicates the too hot state of the soleplate of the iron.
  • This indicator does not go out until the soleplate of the iron has cooled, that is to say when the free end of the bimetallic strip 6 has dropped slightly and occupies a position corresponding to the new desired temperature.
  • the control device for indicator lights according to the invention is applicable to an iron, but can be used on any type of appliance such as ovens, waffle irons, fryers in which the indication of an excessively high temperature must be known to the user.
