Definitions

  • the invention relates to an electric heater, in particular a fan heater with an essentially prismatic housing for electrical components and their switching, regulating and control elements and a heat-dependent actuated safety switch.
  • fan heaters have switching and regulating elements or an operating control lamp arranged in openings in the fan heater housing.
  • the switching and regulating elements are confusing and labor-intensive in connection with the electrical components accommodated in the receiving housing, such as a blower motor, heating element and thermal switch, by means of wire sections serving as electrical conductors.
  • the openings require a considerable mechanical outlay for their manufacture, the openings also lead to a reduction in the stability of the receiving housing.
  • this object is achieved by a rod-shaped housing part arranged transversely horizontally on the outside on an end wall of the receiving housing and / or arranged in this switching, regulating and control elements for the electrical components accommodated in the receiving housing, for. B. blower motor, electric heating element and heat-dependent actuated safety switch and a led out of the housing part, with the switching, regulating and control elements permanently connected wiring harness with a plug connector arranged at the free end of the same.
  • the switching, regulating and control elements e.g. B. an optical display for the operating state, housed together in a single component that is easy to fix on the housing.
  • the wiring harness with the power strip provides the prerequisites for a quick and safe connection of the switching, regulating and control elements with the electrical components in the receptacle housing by means of plug-in operations.
  • the housing part also leads to simplification of assembly because now the switching, regulating and control elements and their actuators including the power cord and wiring harness are arranged on a preassembled component which can be fixed on the receiving housing by clamping or clamping means.
  • the housing part can be connected to the receiving housing in any desired positive or non-positive manner.
  • a z. B. in cross-section T-shaped approach is provided, which can be fixed in the region of the parting plane of the housing halves by clamping action in the case of receiving housings formed from housing halves and fixes the housing part on the receiving housing.
  • the housing part also in other ways, e.g. B. can be fixed by clamping means such as screws or by gluing or welding on the receiving housing.
  • the housing part can be designed with any cross-sectional shape and cross-sectional size.
  • An advantageous embodiment results when the housing part is designed with an essentially rectangular cross-sectional shape.
  • the housing part can be a visible operating control lamp, tiltable actuatable actuators for switches for the blower motor alone, the blower motor with a low power level of the heating element, the blower motor with a large power level of the heating element and a sliding actuator for an actuator of a z.
  • B. have variable resistance for a thermal circuit breaker.
  • the displaceable actuating element can be connected to the actuator with a molding via a longitudinal slot in the housing parts.
  • an additional housing part with the same cross-sectional shape and cross-sectional size is connected to the housing part receiving the switching, regulating and control elements obliquely to the rear side and to the bottom surface, the rear side of which is flush with the rear side of the receiving housing and the latter bottom surface extends to the footprint for the receiving housing.
  • the additional housing part advantageously increases the installation stability of the heater.
  • the two housing parts are expediently one structural unit.
  • the receiving housing 1 is a receiving housing for electrical components (not shown) of the heater, for. B. blower motor, electric heating element, thermostat.
  • the heater housing is provided on the outside with a plurality of ribs 2, which extend over the front 3, the upper side 4 and optionally the rear side 5.
  • the ribs 2 exert a cooling effect on the receiving housing 1.
  • An outlet opening for the blower air is provided in the front 3 in a manner known per se, while the rear side 5 or the rear side 5 and the upper side 4 have supply air openings.
  • the receiving housing 1 is formed by halves 1 'and 1 ⁇ , which are aligned in the area of the common parting plane by a rebate or tongue and groove connection.
  • a housing part 7 is fixedly arranged, which is fixed by means of a molded T-shaped projection 7 'through the two housing parts 1', 1 ⁇ by means of clamping action.
  • the housing part 7 includes the rear to the rear and further housing part 8 extending obliquely to the installation surface.
  • the housing parts 7, 8 are formed by interconnected halves.
  • the housing part 7 accommodates a strip-shaped operating control lamp 9 and, at a distance, two tiltable actuating members 10, 11 for switches accommodated in the housing part, which control the blower motor and heating element parts, and a displaceable actuating member 12 for variably adjusting a thermal switch.
  • a power cable 13 is inserted into the housing part 7 and a cable harness 14 is led out of the housing part 7, the free end of which is a plug connector (not shown) for the connection of the switching, regulating and control elements to the electrical components accommodated in the receiving housing 1 made possible by simple plug-in processes.
  • the actuator 12 is provided to improve handling with gripping surfaces 12 '.
  • identical mirror parts of the housing parts 7, 8 are arranged on the opposite end wall, which can optionally be used to accommodate further switching or control elements.
