Embodiment Construction
[0055] The heat therapy device is assigned the reference numeral 1 in its entirety.
[0056] according to figure 1 , the thermal therapy device 1 includes an inner space 9 in which the patient 8 is located. Patient 8 is especially a premature infant (newborn). In this case, the thermotherapy device 1 is a closed thermotherapy device 1 , ie the inner space 9 is closed from the environment.
[0057] The motor 2 is arranged on the wall 11 , wherein the motor 2 is arranged outside the interior 9 . In a first embodiment, the motor 2 has a motor type-dependent fixed target speed. In a further alternative embodiment, a setpoint value signal input 22 is provided on the motor 2 for actuation, via which the motor 2 receives a setpoint value for the setpoint rotational speed from the outside.
[0058] Furthermore, the motor 2 comprises a parameter signal output 23 via which parameters of the motor 2 can be output. In this case, the parameter is an operating parameter of the motor 2 ...

The invention relates to a thermotherapy device with a motor for detachable connection to a fan impeller, wherein the motor has a parameter signal output, wherein it is provided according to the invention that the thermotherapy device includes a motor with a parameter signal An evaluation unit of the input, wherein the motor transmits a time-dependent parameter signal to the parameter signal input via the parameter signal output and the evaluation unit comprises a substitute value module and a comparator module, wherein the substitute value module is formed between the starter motor and the The time-dependent parameter signal determined between the setpoint rotational speed of the motor forms a substitute value for the moment of inertia accelerated by the motor, and the comparator module is designed to compare the substitute value with a predetermined threshold value. Furthermore, a corresponding method is the object of the invention. The invention provides a device and a method which allow a fast and reliable detection of a defective fan impeller without significant effort.
Description
technical field [0001] The invention provides a thermotherapy device with a motor for detachable connection to a fan impeller, wherein the motor has a parameter signal output. [0002] Patients requiring a constant ambient temperature are treated in a thermotherapy device. The ambient temperature is generally also heated. In this case, the thermotherapy device, which can be configured as an incubator, includes a fan impeller for air circulation in order to avoid thermal inhomogeneities in the thermotherapy device and the resulting health risks for the patient. The fan wheel is motorized and removable from the motor for easy cleaning. However, there is the risk that the ventilator is no longer attached to the motor after cleaning by mistake. Air circulation can no longer be generated afterwards. This can pose a health risk for the patient. Background technique [0003] In order to avoid this risk, it is known to place a sensor below the fan wheel, which sensor detects th...
