ELECTRIC SHOWER Russian patent published in 2001 - IPC

FIELD: shower with electric heating of water. SUBSTANCE: shower includes housing in the form of sink having four portions made of polymeric material by injection molding. First portion is in the form of housing 1 spherically bent upwards or in the form of tilted sink whose bottom is turned upwards and whose lower part is open. Said lower part has cylindrical groove 2 for engaging with separation disc 3. Under disc 3 there is grid or dispersing member 4 arranged in such way that first dispersing chamber 5 is formed between member 4 and disc 3. Chamber 5 has tubular outlet 6 for manual minishower. Water or heating chamber 7 is formed in housing 1. Chamber 7 has back connection branch pipe 8 for introducing water and its upper portion is restricted by intermediate horizontal wall 9 over which there is dry chamber 10. Said chamber is designed for mounting electric circuit or electric mechanism 11 with movable contacts and it is arranged in upper portion of closed device 12 for selecting temperature. Water is fed through branch pipe 8 and fills heating chamber 7 which at normal condition is filled with water. That is why resistor 15 remains immersed in water. Water fed to chamber 7 causes pressure increase sufficient for moving diaphragm 15 and for shifting plate 18 that provides closing of contacts 28-29 and applying of electric current from power supply line F to resistor 25. EFFECT: enhanced efficiency of heating members. 14 cl, 22 dwg
