Definitions

  • the control device for an electrically heated sauna room includes a liquid filled temperature sensing body [52] U S Cl 337/322 236/30 located inside the sauna room and communicating [5H 6 3/24 with the control device proper located outside the [58] Fie'ld I 17 room.
  • the sensing body is made of elastically deform- 3 206/81 able material and may, in case of accident, be compressed by means of a lever, thus bringing about an [56] References Cited immediate action upon the control device for breaking t UNITED STATES PATENTS p the l,849,48l 3/1932 DeLangie et al.
  • the purpose of the invention is to 'make it possible to shut off the heating unit from inside the sauna room with the aid of uncomplicated means and without the need of electric control apparatus or connections inside the sauna room.
  • the invention relates to a safety device for sauna rooms provided with an electric heating unit having a thermostatically governed power control including a liquid-filled sensing body located inside the sauna room and communicating with a pressure bellows located outside said room for acting upon the power control.
  • the invention is characterized in that the sensing body is elastically deformable, and that a manually operated member is fitted for mechanically compressing the sensing body.
  • FIG. 1 is a schematic view of a power control and a safety device according to the invention cooperating therewith, when the safety device is at normal working conditions,.and
  • FIG. 2 is a corresponding view when the safety device has been operated to cut out the heating unit.
  • a power control having two contacts 11 and 12, which are connected to the current circuit (25) leading to an electric heating unit (26).
  • One of the contacts 12 is a movable element, and it is operated by means of a pressure bellows 13, which through a capillary tube 14 of suitable length communicates with an elongated tubular sensing body 15 of elastically deformable material, which is fitted inside the sauna room, to be exposed to the temperature therein.
  • the power control 10 proper shall be located outside the sauna room.
  • the pressure bellows 13, the capillary tube 14 and the sensing body 15 together form a communicating system, which is filled with a liquid.
  • the sensing body 15 is retained in its position between a bar 16 fitted to a plate 17, which may be attached to the sauna room wall, and a jaw 18, which is pivotably fitted to the plate 17 by means of a journal 19 and is provided with a lever 20.
  • a jaw 18 and the lever 20 have the position shown in FIG. 1, and they may be retained in this position by means of any kind of spring lock, or an easily breakable stop, e.g. a sealed wire.
  • the sensing body 15, which is located between bar 16 and jaw 18 thereby acts in a normalway to control the opening and the closing of the movable contact 12in relation to the temperature conditions in the sauna room, and thereby also the expansion and the contraction, respectively, of the liquid in the communicating system 13, 14 and 15.
  • the lever 20 is turned in the direction of arrow 21 to the position shown in FIG. 2, whereby jaw 18 presses a central portion of the sensing body 15 against bar 16, which acts as a fixed counter-jaw during deformation of the sensing body.
  • liquid is pressed from the sensing body according to arrow 22, through the capillary tube 14 into the bellows 13. This will expand due to the increasing liquid pressure therein and acts on the movable contact 12, with a breaking of the current circuit to the heating unit as a result, all in accordance with what is shown in FIG. 2.
  • the safety device shown and described is very simple and useful and is easily operated also for a technically unskilled person.
  • the device requires no electric control component in the sauna room, but works through the already present sensing body and the associated capillary tube as a transforming member between the sauna room and the power control, which is located outside this room.
  • the device furtheracts as a holder for the sensing body, which is an additional advantage. It is of course, possible to give the jaw-arrangement another design, and the invention may therefore in no way be considered as limited to the embodiment shown here.
  • a safety device for sauna rooms provided with an electric heating unit having a thermostatically governed power control including a liquid-filled sensing body located inside the sauna room and communicating with a pressure bellows located outside said room for acting upon the power control, the improvement comprising; the sensing body being comprised of an elastically deformable material and a manually operated means is fitted for mechanically compressing of the sensing body.
  • the manually operated means includes a pivoted lever having a jaw for pressing the sensing body against a fixed counter-jaw.
  • the safety device in which the manually operated means includes a pivoted lever and is journalled on a plate carrying a counter-jaw.
  • the sensing body includes an elongated tubular member which is fitted to the plate between the lever and the counter-jaw, which together act as a holder for the sensing body.
  • said means includes a pivoted lever, which lever has a jaw adjustable towards a central portion of the sensing body for pressing this portion against a straight bar acting as counter-jaw.
