Before the start of operation, the heater is checked for objects placed on it, so that it is ensured that even with a remote control Commissioning a safe heating of the heater is possible.
- a temperature detection element detects the temperature of the heater. So it can be easily determined when the heater has reached a target temperature and a shutdown of the safety device can take place.
- the setpoint temperature is felt by a user, so that it easily recognizes that the stove is in operation and there are no objects can be deposited.
- the safety device according to the invention comprises in a first
- a control device for controlling a heater with a AufMapungsüberwachungsanssen with at least one temperature sensing element, a data memory for storing time-dependent temperature curves, a karseinrich- device for comparing a time-dependent actual with a setpoint temperature and a signaling device, wherein in case of failure of the Auftropics- monitoring arrangement by means of Signaling device is a warning signal can be signaled.
- a safety device can easily be integrated in a digital control of a cabin or a heater.
- any temperature curves can be stored, whereby a particularly simple adaptability of the safety device is achieved. If there is a failure of a component of the safety device, for example the data processing device, this failure is easily detectable and a warning signal can be signaled.
- the temperature sensing element may serve to detect a room temperature of a cabin.
- a single temperature sensing element can be used as part of the safety device and for controlling the heater in the control mode.
- an infrared sensor may be used as a temperature detecting element for non-contact detection of a temperature of a heater surface. An infrared sensor positioned at a distance above the heater can thus detect the temperature of an upper heater surface so that it can be determined immediately when an object is deposited on the heater. Also, the surface temperature of heating elements of the heater can be detected, with an object not properly placed over the heating elements having a comparatively low surface temperature.
- the safety device has a control device for controlling a heater with a car monitoring arrangement with at least one temperature detection element for detecting the temperature of the heater, a car access detection element for monitoring a car access, a release switch for enabling the control device and a signaling device on, in case of failure of the car monitoring arrangement by means of the signaling device, a warning signal can be signaled.
- a cabin monitoring arrangement can be easily integrated in an analog control of a cabin or a heater.
- the safety device can easily be issued a warning signal.
- the release switch can be formed, for example, as a manually operable button on the control device.
- the car access sensing element may be configured as a door contact switch installed on the door or as a motion detector disposed in the cabin.
- a closed cabin access is detectable by means of the car monitoring arrangement and below the setpoint temperature is a relay with an electromagnetic, self-holding drive by means of the release switch is actuated, so that the heater by means of the control device is switched on, wherein the relay by means of an open cabin access in an unactuated state can be brought, so that the heater by means of the control device is switched off, and wherein a fate of the relay in the actuated state, for example by a malfunction of the relay, a warning signal is signaled.
- the temperature sensing element may be a bimetallic switch. With such a switch, a setpoint temperature can easily be detected and converted into a mechanical switching signal.
- a bimetallic switch is particularly suitable for the temperature detection of a heater.
