Definitions

  • thermostat sensing element is held, in a zone not subjected directly to the thermal action of the burner, in a starting position from which it is moved, by contact with the vessel to be heated as this vessel is placed in position on the burner, into a working position in which it is pushed firmly against the vessel by a spring.
  • the sensing element can be moved upwardly, by pivoting about a horizontal axis, into a retracted position to facilitate cleaning of the burner; this upward retraction can be controlled manually from a handle.
  • the sensing element can be retracted laterally, either as well as or instead of the upward retraction, and this lateral retraction can be controlled manually from a knob.
  • the invention relates to thermostatic control means for vessels subjected to a thermal action, in particular for equipment for domestic appliances such as cookers, kitchen ranges, etc.
  • sensing element which can be held, in a zone not subjected directly to the thermal action of the source or of the burner, in a position such that when the vessel is brought into the heating position it can contact said sensing element and push it back in opposition to a resilient action, the sensing element being preferably mounted in such manner that it can be retracted when desired.

  • FIG. 14 is a section similar to that of FIG. 11 in another position
  • FIG. 15 is a section similar to FIG. 11, but again in another position.
  • the burner 1 of the type having a cover allowing the flames to escape laterally, belongs to a stove or cooker the spill tray of which can be seen at 3, with the usual recess of dished portion 4 provided around the burner and designed to receive any fat, splashes or spills, etc. from the saucepan 5.
  • thermostatic device which comprises:
  • a sensing element 8 carried by a support 9 mounted at the end of an arm 10 articulated, for example, by means of a yoke 17 on a spindle 11 arranged laterally of the burner, and opposing the action of a spring 12 tending to raise the sensing element 8, accordingly in the direction of the arrowf(FIG. 1),
  • thermostat proper which is not visible in the drawing and to which the sensing element 8 (constituted, for example, by a liquid diaphragm or liquid capsule) is connected, again by way of example, by a flexible capillary tube 16, if a liquid-type thermostat is concerned, it being understood that any other type of thermostat could be used.
  • the support 9 of the sensing element is provided with lateral lugs 13 on which the central portions 14 of the bars 6 can bear, these central portions being bent to this end towards the burner.
  • the assembly consisting of the sensing element 8, 9 and its arm 10 is shifted in the opposite direction to that of the arrow f so as to adopt the position shown in FIG. 1, in which the sensing element proper 8 projects slightly with respect to the bars 6, 7.
  • the sensing element is disposed along the axis of the burner, it is protected from the action of the flames as these are lateral and it can be considered that its temperature is substantially the same as that of the saucepan and its contents.
  • FIG. 3 showing the position assumed by the assembly when the bars 6 are removed for this cleaning operation.
  • the arm 10 then adopts a raised position together with the support 9 and the sensing element 8, so that the user is in no way impeded in the cleaning of said dished portion.
  • FIG. 4 shows a modified construction in which the assembly is fitted to another type of cooker or stove in which the dished portion such as 4 is sunk further with respect to the upper edge of the top 3 of the cooker or stove.
  • the arm 10, which is bent in the construction of FIG. 1 may be substantially straight, as shown in FIG. 4.
  • the spindle 11 on which the am 10 pivots can be disposed below the spill tray or top, the arm 10 extending therethrough an opening such as 15.
  • means are provided, for example of the lever type, for enabling the sensing element to be put into or out of action at will. It can be assumed that the putting out of action is obtained as hereinbefore by raising, in particular for cleaning purposes, that is to say by pivoting about a horizontal axis (constructional form shown in FIGS. 5 to 8). It is also possible to provide lateral retraction (FIGS. 9 to 15) when it is not desired to make use of the thermostatic action.
  • Means may moreover by provided, for example, for adjusting the upper position of the sensing element.
  • a handie 18 is used which is adapted to turn about an axis xx, for example parallel to the top 3 of the cooker, and carry along a kind of elbowed lever 19 arranged in such manner that, again for example:
  • said lever I9 locks the yoke or other part 17 articulated on the spindle 11 and serving as a foot or support for the assembly, more particularly by means of an elbow 20 (FIG. 5
  • the spring 12 is mounted in spiral form on the spindle 11 and that its two ends bear, on the one hand, against an angle iron 21 fast with the fixed frame and, on the other hand, against another angle iron constituting the part 17 aforesaid.
  • the arm 10 is connected to this part 17 by a leg 22 having, for instance, a cylindrical form with its axis substantially coinciding with the spindle 11. This form permits free movement of the capsule 8 and its support under the effect of the placing in position of the saucepan, without being hindered by the elbowed lever 19, 20.
  • Said leg extends through the spill tray or top 3 by way of an elongated opening 23.
  • FIGS. 9 to 15 which relate to the use of means adapted to enable the sensing element and its support to be brought into a retracted position when it is not desired to make use of the thermostatic action
  • the procedure adopted is, for example, as follows.
  • FIGS. 9 and 10 illustrate an assembly of the above-mentioned kind, with a sensing unit 8, 9 placed in the operative position by the action of the bars 6 (the latter bearing at 14 on the lugs 13 of the support 9 of the sensing element).
  • the arm 10 of the sensing unit 8, 9 is then mounted pivotally on a vertical axis 24 arranged at the side and taking the form, for example, of a vertical elbowed portion forming an extension of the arm 10.
  • the retraction can be efl'ected either directly with the hand by acting on the arm 10, or with the aid of operating means, for example controlled by a knob such as 25, such as the means described hereinafter with reference to FIGS. 11 to 15.
  • the arm 10 is continued by an elbow 24 acting as a pivot, which pivot is engaged freely in the flanges 26, which are suitably drilled to this end, of the supporting part 17 serving as a seat.
  • the assembly consisting of this support and the arm 10, 24 is again articulated in this case on the horizontal spindle 11, said part 17 being subjected to the action of the return spring 12.
  • the pivot 24 moreover extends through a fixed plate 29 by way of an elongated aperture (or the slot 35 referred to hereinafter) and it is rendered fast at its free end with an arm 27 terminating in a fork 30 the function of which will be described, and adjusting screw 31 extending through said arm and the free end thereof bearing against the plate 29 under the effect of a spiral spring 32 mounted on the pivot 24 and tending to urge the whole assembly upwardly.
  • This screw 31 would in any case enable the initial position of the sensing element 8 in its working location to be adjusted, but it is understood that this combination could be used independently, even in assemblies other that that shown in FIGS. 11 to 15, for example with a sensing element of the kind shown in FIGS. I to 8.
  • the arm 27 with its fork 30 will therefore be made to pass from the position shown in solid lines in FIG. 13 to the position at therefrom shown by a chaindottedline.
  • the fork 30 it will only be possible to act on the fork 30 by applying pressure to the knob 25 in the direction of the axis yy, in combination with suitable engaging means, as generally occurs with the control knobs of cookers.
  • This raising will be effected, for example, by a pivoting action about the spindle l 1, as shown in FIG. 15.
