US 5,178,523 A · Auxiliary package for a bath-pool

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.

a housing having a water inlet for receiving the water from said bath-pool, a water exit for sending the water back to said bath-pool and a plurality of partition walls for dividing the interior of said housing into a plurality of chambers and forming a water passage therein;
a water pump mounted in one of said chambers for sucking the water from said inlet and circulating the water through said passage to said bath-pool;
an electric motor for driving said water pump, said motor being capable of heat exchange with the water flowing in said passage;
a control box for controlling said electric motor, said control box being mounted water tight on said housing;
electric plug means connected to a power supply for receiving electrical power required for said auxiliary package;
heating means mounted in said water passage for heating the water flowing in said water passage, said heating means comprising a heating tube and a heating wire received in said heating tube;
temperature adjusting means for adjusting the temperature of the water flowing in said water passage;
a temperature limit switch for restricting the temperature of the water under a predetermined limit temperature, said temperature limit switch including a temperature sensing tube, one section of said temperature sensing tube being welded to said electrical heating device for directly sensing the temperature;
a metal plate disposed on a common wall between said housing and said control box,
wherein one side of the metal plate is in direct contact with said water, said temperature sensing tube and heating tube are inserted water tight through and fixed on said metal plate and are supported on said housing by heat insulting material, and
said metal plate functions as an electricity collector for detecting ground fault.
