Definitions
- the invention relates to a heating assembly for heating one in a flow channel a tumble dryer flowing hot air stream, wherein the heating assembly in the Flow channel is configured usable and at least one heating element of the Hot air flow is arranged flow around in a flow direction, and at least a temperature sensor, by means of which the temperature of the hot air flow can be detected, includes.
- the Hot air flow is from an air supply through the usually between the drum and a rear wall of the tumble dryer flow channel extending into the drum into and through the wet laundry.
- a heating module used, which heats the hot air flow with at least one heating element.
- at least one temperature sensor determines the temperature of the hot air flow. When a predetermined limit temperature is exceeded, the heating element switched off by the control unit of the clothes dryer.
- Such a temperature control allows drying of the laundry with a textile suitable Temperature. In addition, this is to prevent this, that the rear wall of the tumble dryer heated excessively, and thereby the reliability of the Tumble dryer is at risk.
- the temperature measurement is inaccurate, so that it leads to overheating of the heating elements and thus to exceeding the for a gentle drying maximum permissible temperature and to an impermissible Heating the outer wall of the tumble dryer may come.
- the present invention is based on the object to provide a heating assembly, in which the temperature control performed more accurately can be.
- this object is achieved in that the at least one temperature sensor is arranged projecting into a core region of the hot air flow.
- This solution is structurally simple and allows a more accurate temperature control by a more exact temperature determination of the hot air flow.
- the core area lying inside the hot air flow becomes heated more strongly by the heating element than the outer jacket region, the e.g. is cooled faster by the cold wall of the flow channel and / or flows only indirectly along the heating element.
- the only so far in the jacket area measured temperature of the hot air flow was therefore not for the temperature control relevant maximum temperature and not representative of the maximum temperature the hot air stream.
- the maximum temperature be determined so reliably that the permissible limit temperature of the hot air flow is no longer exceeded. Consequently, neither the textiles to be dried become exposed to high temperatures, which can lead to their damage, nor heats the outside wall of the tumble dryer rises above the permissible temperatures.
