Definitions

  • the invention relates to a device for supporting control means for a household appliance which, mobile, makes it possible to modify the aesthetics of the appliance according to whether or not it is in operation and to ensure correct ventilation for its cooling in operation. .
  • the power electronics In the case of induction hobs, the power electronics must be cooled and, to do this, it is known to place it in a ventilation circuit which extends under the hob from the rear of the 'appliance (crawl space) to the front where holes are provided for the outlet of hot air.
  • a ventilation circuit which extends under the hob from the rear of the 'appliance (crawl space) to the front where holes are provided for the outlet of hot air.
  • the invention makes it possible in all cases to preserve a correct construction of the ventilation circuit, in particular in the case of built-in appliances, by means of a particular mounting and embodiment of the support strip for the control means (buttons, keys, etc.). ) of the device.
  • This arrangement also makes it possible to modify the aesthetics of the device by masking these means when the device is not in operation.
  • the invention provides a device for supporting the control means for a device enclosed at least in part in a housing provided with an internal ventilation circuit having an outlet orifice near the control means, this device comprising a body mounted on the housing having a face on which the control means are arranged, this body being movable between a first position, where the control means are accessible, and a second position, where they are not and constituting a member opening the outlet in its first position and a member for closing the outlet orifice in its second position.
  • the body comprises a passage having a first end opening into the housing and a second end opening close to the face where the control means are arranged and opening to the outside when the body is in the first position, this second end constituting the outlet orifice.
  • FIG 1 there is shown a hob 1 with induction heating embedded in a cabinet 2 comprising a crawl space 3 in its rear part.
  • the hob 1 comprises a plate 4 supporting several heating plates 5 connected, in a manner known per se, to an electronic power system constituted by cards circuit 6 extending under the plates 5.
  • the assembly is enclosed in a housing 7, the plate 4 of which forms the upper wall.
  • the hob 1 further comprises a ventilation circuit for cooling the electronic system.
  • This circuit includes a fan 8 mounted near the rear wall of the housing 7 and streamlined so as to discharge air in a direction substantially parallel to the electronic circuit boards 6.
  • the bottom of the housing 7 comprises an orifice 9 which is therefore located at the base of the crawl space 3, and by which the suction of the forced air takes place in the housing 7.
  • control means 10 buttons, keys or the like
  • the control means are supported by the device according to the invention, which comprises a control panel 11 constituted by one face of an elongated body 12 mounted on the housing 7 so as to be able to pivot by approximately 90 ° around its longitudinal axis, between a position where the strip 11 is completely visible ( Figure 1) and a position where it is not visible ( Figure 2).
  • the body 12 is returned to one and the other of these positions by elastic means (not shown).
  • the body 12 comprises cells in which the control means are partially embedded as well as the connections of these control means to the cables which connect them to the electronic system.
  • the body 12 also includes a recess 13, the bottom of which extends substantially perpendicular to the front edge of the control panel 11.
  • This clearance delimits a passage, a first end of which always opens out inside the housing 7 and the second end of which opens either outside the housing 7, when the body 12 is tilted in the position illustrated in FIG. 1, that is to say inside the housing, when the body 12 is tilted in the position illustrated in FIG. 2.
  • This second end constitutes the outlet orifice of the ventilation circuit, which is therefore open or closed depending on whether the body is tilted in one or the other of its two positions.
  • FIGs 3 and 4 show a second embodiment of the support device according to the invention.
  • This device comprises an elongated body 15 of rectangular section having an upper face constituting the control panel 11.
  • the body 15 is guided in translation against the front wall of the housing 7, in a direction perpendicular to the plate 4.
  • the body 15 is movable between a position where the control panel 11 is pressed relative to the plate 4 (FIG. 3) and a position where the control panel is projecting relative to the plate (FIG. 4).
  • It includes a clearance 16 opening on its underside and on its face contiguous to the housing 7, so that, when it is in the projecting position relative to the plate 4, one end of this clearance opens onto the outside and constitutes the ventilation circuit outlet.
  • a flat cover 17 is pivotally mounted on the housing 7 by lateral L-shaped legs 18 having a segment parallel to the cover, the pivot axis being parallel to the upper face of the body 15 and passing at the free end of the legs 18. Closing this cover causes the body 15 to be pushed into the housing 7 and locked in the depressed position.
  • FIGS 5, 6, 7 there is shown a third embodiment of the device according to the invention.
  • a protective screen 20 is secured to an elongated body 21, one face of which constitutes the control panel 11 of a hob.
  • This screen which extends along the rear part of the body 21 and is inclined by approximately 90 ° relative to the control panel 11, is intended to protect the latter from a flow of liquid due to spillage or overflow. of a pan.
  • the body 21 is pivotally mounted on the housing 7 about an axis parallel to the edge of the front wall of the housing 7 and which is substantially coincident with the rear edge of the screen 20.
  • the body 21 comprises a passage 22 extending transversely to the screen 20, along this screen, and opening on the one hand into the housing 7 and, on the other hand, at the rear edge of the control panel 11.
  • the body 21 is subjected to the action of an elastic member associated with a set of stops (not shown) tending to return the body 21 and the screen 20 to one of the three positions illustrated in FIGS. 5, 6, 7.
  • the screen 20 closes the box 7 and the control panel 11 is not visible.
  • the second position (hob in operation)
  • the screen 20 is raised to the maximum, the control panel 11 is visible and the front part of the body 21 is in abutment against the front wall of the housing 7: the passage 22 puts then in communication inside the box 7 with the outside.
  • the screen 20 occupies a intermediate position, manipulation of the control means is not possible; however, the hob can operate, the ventilation air being able to escape from the housing 7 along the paths represented by the arrows.
  • This third position provides maximum protection to the control panel 11 while it prohibits the modification of the setting of the heating of the plates.
  • the devices shown in Figures 3,4 and 5,6,7 respectively can be fitted with a safety device cutting off the power to the hob when the cover 17 or the screen 20 is folded down in the plane of the plate 4, that is to say when the outlet orifice of the ventilation circuit is closed.
  • the operation of the device for supporting the control means 10 associated with the hob 1, shown in FIG. 1, is as follows. To use the hob, the body 12 is tilted so as to reveal the control panel 11. The switch placed on the hob supply circuit is then closed. By manipulating one of the control means 10, both the fan 8 and the heating of the corresponding plate 5 are brought on. The fan 8 draws air into the crawl space 3 through the suction opening 9. The air blown by the fan into the housing 7 flows along the electronic circuit boards 6 then, after having heated and having cooled said cards, escapes through the outlet orifice formed by the end of the clearance 13 of the body 10 opening to the outside. If, during operation, the body 12 was involuntarily tilted in the opposite direction, the supply to the hob would be automatically cut off.
  • the invention is not limited to the embodiments shown and is capable of variant embodiments.
