ABSTRACT:
An auxiliary package for a bath-pool, particularly for a sauna bath-pool, comprising a housing having a water inlet for receiving water from the bath-pool, a water exit for sending the water back to the bath-pool and a plurality of partition walls for dividing the interior of the housing into a plurality of chambers and forming a water passage therein, a water pump mounted in one of the chambers for sucking the water from the inlet and circulating the water through the passage to the bath-pool, an electric motor mounted in one of the chambers for driving the water pump capable of transfering the heat generated to the water flowing in the passage, a control box for controlling the electric motor, which is mounted watertight on the housing, and electric plug means adapted for connection to a power system for receiving electrical power. As the water pump, the motor and the filter of the package are all mounted in a housing, the auxiliary package of the present invention can be made more compact than prior known auxiliary packages for sauna bath-pools. Another advantage of the auxiliary package of the present invention is that the heat generated by the motor can be used to preheat the water from the sauna bath-pool to save energy. Furthermore, the water pump, motor and filter are provided with sealing covers so as to make them watertight, and each sealing cover also is provided with a microswitch to cut off the power when any of the sealing covers is opened.
