Definitions

  • the present invention refers to an improved tehrmostat, particularly to a bimetallic thermostat for electric cabinets.
  • thermostats for industrial applications are known in the art; however, they have some limits, that in detail are:
  • Object of the present invention is solving the above prior-art problems, by providing an improved thermostat that simultaneously integrates the different functionalities that are individually provided by the thermo-adjusting devices belonging to the prior art.
  • the thermostat of the present invention adopts technical solutions that allow performing assembling, installation and user-need customisation operations of the thermostat itself with lower difficulties and costs than the already existing devices.
  • the thermostat of the invention will be suitable for different applications, such as: anti-condensate resistances (normally closed version) , fans-filters and exchangers (normally open version) , and will be able to guarantee high performance and maximum reliability. Its two major features are:
  • FIG. 1 is an exploded view of an embodiment of the thermostat of the present invention
  • Figure 2 shows a side view of the internal device of an embodiment of the thermostat of the present invention
  • Figure 3 shows a perspective view of the thermostat in Fig. 1 in an assembled condition
  • FIG. 4 shows a cascade connection (of the
  • Figure 5 shows four possible assemblings on as many standardised bars profiles (DIN, EN, ...) of the thermostat in Fig. 3.
  • connection terminal in fact is realised by following the remote control switch scheme, and allows inserting at least two 4x4-mm wires contrary to the already existing devices, that allow inserting a single wire whose diameter is 2.5 mm: this arrangement allows an easy cascade connection of many thermostats 1 according to the present invention.
  • Such terminal is composed of a nut 3a, a screw 3b and a connection wing 3c: such connection wing 3c is aimed to simultaneously perform the functions of completing the terminal and connecting the terminal itself to the bimetal 5.
  • Such screw 3b has a double-cut (co bi) head: with a cut for a manual operation, with a cross for an operation with a screwing device; the head is sized in order to be perfectly coupled with a screwdriver (for example of -type 3), that is the one standardly used in electric wiring.
  • a screwdriver for example of -type 3
  • Such screw 3b can be actuated from outside the housing through an hole facing it that is present on the upper cover 2a, that is also sized in order to allow an easy access to a type-3 screwdriver.
  • the lower cover 2b is equipped with particular securing means 6 that allow the thermostat 1 according to the present invention to be assembled on all currently-used profiles (for example DIN 46277-1, DIN 46277-2, EN 50-022 and DIN 46277-2, as can be well seen in Fig. 5) through a plurality of supports 6 complementary thereto.
  • all currently-used profiles for example DIN 46277-1, DIN 46277-2, EN 50-022 and DIN 46277-2, as can be well seen in Fig. 5
  • the thermostat 1 has a device, whose operation is known in the art, contained inside the housing composed of the upper cover 2a and the lower cover 2b beng kept joined by the closing screw 8, whose characteristic sizes are such as to allow the interchangeability of the bimetal 5 with the one from other manufacturers .
  • the exchange of the bimetal 5 however implies the need of moving the reference scale that can be found on the adjusting wheel 4a: in order to solve this inconvenience, a rotating silk-screened scale 4b is adopted, instead of a fixed scale, in order to adapt the thermostat to the different bimetals, without having to perform costly and long modifications of plastics injection molds .
  • At least one pair of wires 14 can be applied to every terminal of the thermostat 1, thereby allowing to realise a cascade connection of various thermostats 1, as can be seen in Fig. 4.
  • thermostat 1 terminal is made integral with the thermostat 1 itself without using external terminals, and is build flexibly in order not to damage the thermostat 1 when tightening the screws 7.
