Definitions

  • the invention relates to a device for ventilating a room, in particular a toilet, consisting of a fan wheel which is arranged in a housing and can be driven by an electric motor which can be switched on if required, and fan flaps which are mounted on the housing and can be pivoted into an open position via a rod and which are clamped on one side , electrically heatable and the rod adjustable bimetallic strip and from a short distance from the clamping point on the bimetallic strip, designed as a PTC resistor.
  • Such a device is known from DE-0S 31 00 232.
  • an operating switch for example a light switch or a door contact switch
  • the circuit for the heating element or the PTC resistor is closed.
  • This heating element gradually heats up and with it the bimetal strip.
  • the bimetallic strip has the property that it gradually deforms or bends as it heats up.
  • the deformation of the bimetal strip which causes the fan flaps to open begins at the earliest after 60 seconds; As soon as the bimetal strip has reached its saturation temperature, the fan flaps are fully open. This is relative Slow opening of the fan flaps means that the electric motor has to be switched on with a delay.
  • a thermal switch is arranged on the bimetal strip in the area of the heating element, which responds, for example, at a temperature of 60 degrees Celsius and closes the circuit for the electric motor, so that the fan wheel is put into operation.
  • the thermal switch also has the task of ensuring the power supply to the electric motor of the fan for a certain run-on time. As soon as the thermal switch drops below a temperature of, for example, less than 50 degrees Celsius, the circuit for the electric motor is interrupted again and the fan wheel is shut down.
  • the invention is based on the object of designing a device for ventilating a room, in particular a toilet, in such a way that the normally closed fan flaps begin their opening shortly after the operating switch is actuated and assume their fully open position after 10 seconds at the latest, so that the electric motor can start immediately and no special delay is required.
  • a second heating element is arranged on the bimetal strip at a distance from the first heating element.
  • This configuration ensures that the bimetallic strip heats up very quickly after the operating switch is actuated and the opening movement of the fan flaps is initiated within a very short time after the operating switch has been actuated.
  • the fan flaps are fully open at the latest 10 seconds after the operating switch has been actuated, so that the electric motor for the fan wheel can start immediately with the actuation of the operating switch.
  • a special delay device is therefore no longer required. This has the advantage that the device is also effective within a very short time after the operating switch has been actuated.
  • FIG. 1 Of a device for ventilating a room, only one frame 2 is shown in FIG. 1, which carries a plurality of pivotably mounted fan flaps 3. To mount the fan flaps 3, they are provided with pins (not shown in more detail), each of which carries a swivel arm 4 on one side of the frame 2. All swivel arms 4 are connected to one another by a common rod 5. When the rod 5 moves in the direction of the arrow 6, all the swivel arms 4 are moved and thus all the fan flaps 3 are moved into the open position (not shown).
  • the other end 7b of the bimetallic strip 7 is either with one Screw 8 clamped in place or secured in a manner not shown so that it can be inserted between retaining pins by appropriate shaping.
  • the bimetal strip 7 carries a heating element 9, which is formed by a PTC resistor or a PTC thermistor element.
  • a further heating element 10 is provided, which is designed in the same way as the heating element 9.
  • the heating elements 9, 10 are designed as so-called pills and have a diameter of approximately 10 mm and a height of approximately 3 mm.
  • the two heating elements 9, 10 are arranged in a circuit between phase L and the zero potential N of a mains voltage of 220 volts.
  • this circuit there is also an electric motor 11 for driving a fan wheel.
  • the circuit is closed and the electric motor 7 is switched on via an operating switch 12, which is formed, for example, by a light switch, a button or a door contact.
  • the heating elements 9, 10 begin to heat up. This heating causes the bimetallic strip 7 to begin to deform within a very short time after the operating switch 12 has been actuated. So that the rod 5 is moved in the direction of arrow 6 and the fan flaps 3 begin to open.
  • the bimetal strip 7 has reached its end position at the latest 10 seconds after the operating switch 12 has been actuated, and the fan flaps 3 are fully open.
