Definitions

  • the present invention relates to a household appliance, in particular gas and electric range, including a movable cover and a safety device.
  • the electrical household appliance in its rest condition, is not or can not be actuated by erroneous operations, for example in a mixed gas and electrically supplied range, or, as it frequently occurs, by children handling the control knobs of the apparatus, with a consequent very great danger.
  • thermocouples have been developed, specifically designed for locking the gas outflow as the flame is lacking, which systems are usually based on the use of thermocouples.
  • Another system which is mainly used in northern countries provides for the use of mechanical shutoff valves which are driven as the appliance cover is displaced, thereby exclusively with the cover in its open condition the gas ejectors of the appliance are supplied with gas.
  • control knobs it is possible to operate the control knobs to their open condition both with the cover open and with the cover closed, which thing represents a possible dangerous situation.
  • the document US-A-2 059 735 discloses a household appliance, in particular gas electric range, having substantially the features of the preamble of the main claim.
  • the aim of the present invention is to solve the above mentioned problem, by providing a safety device for household appliances, including a cover to be driven during the use of the appliance, in particular for gas and electric ranges, which is adapted to prevent the control knobs of the appliances from being operated as the cover is in its closed condition.
  • a main object of the present invention is to provide such a safety device which can be used in association with or in replacement of the conventional integral safety systems such as thermocouples, used in cooperation with thermoresponsive locking systems, or mechanical locking systems, such as cam systems operating on the shaft or stem of the control knobs, so as to prevent the cover of the appliance from being closed as the knob is turned for a set angle.
  • conventional integral safety systems such as thermocouples, used in cooperation with thermoresponsive locking systems, or mechanical locking systems, such as cam systems operating on the shaft or stem of the control knobs, so as to prevent the cover of the appliance from being closed as the knob is turned for a set angle.
  • Yet another object of the present invention is to provide such a safety device for household appliances which is very simple construction-wise and which can be easily fitted to existing household appliances.
  • Yet another object of the present invention is to provide such a safety device which is very reliable in operation and which can be easily made starting from easily commercially available elements and materials and which, accordingly, is very competitive from a mere economic standpoint.
  • the safety device for household appliances including a movable cover, in particular for gas and electric ranges, according to the present invention, comprises a slider element which practically provides the "control dashboard" of a range generically indicated at the reference number 2.
  • the slider element 1 is provided with a plurality of recesses 3, in which there are arranged the control knobs 4 which can operate in order to actuate the several flames or electric plates of the range.
  • the slider element 1 can be moved to a first position, shown in Figure 1, which will be called the "safety position" since said slider element is arranged flush with respect to the front portion of the control knob 4 so as to prevent the latter from being operated, even deliberately.
  • the slider element can be moved to a second position, in which the slider is withdrawn, thereby the control knobs project from said slider so as to allow the control knobs to be operated.
  • the slider element can also operates as a safety element for the opening of the range oven since, by its bottom edge portion, it can close the slot for accessing the profiled U-shape cross-section element 7 of the door 8 of the oven which, accordingly, can not be actuated.
  • the mentioned slider element is slidably driven by driving means, which are operatively associated with the cover 10 of the range.
  • these driving means comprises a small cable 16 which, at one end thereof, is associated with the hinge 20 of the cover 10 and is entrained on a transmission roller 21 supported, for example, by the sidewalls of the range casing or cabinet.
  • the cable 16 is connected to one end of a lever 22 pivoted to the fixed structure, at its intermediate position, and controlled by a flexure spring 23 operating between, said lever and the fixed casing or structure.
  • the lever 22 engages in the slot 26 of the sidewalls 27 coupled to the slider element and supported by guide wheels 28 which are slidably engaged in a supporting section member or profiled element 29 associated with the range side walls.
  • the cable 16 will overcome the resilient biassing of the flexure spring 23, thereby the lever 22 will be turned so that its end portion 24 will hold the sidewalls 27 and, accordingly, the slider element 1 at an advanced position, that is the first position, or safe position, in which said slider element will be flush with the front portion of the control knobs, which, accordingly, can not be actuated.
  • the driving means practically comprise a flexible element provided for driving the lever 22, depending on the specific position of the cover, so as to prevent the control knobs from being operated as the cover is in its closure position.
  • the slider element in addition to providing the safety of the device, also offers the great advantages of providing the range with a very good aesthetic aspect, since it provides a frontal alignment of the dashboard, to prevent the control knobs from projecting as the cover is in its closure condition.
