Apparatus and a method for the disinfection of water for water consumption units designed for health or dental care purposes
First Claim
1. Apparatus for the disinfection of water for water consumption units (3) designed for health or dental care purposes, wherein the same comprises a main valve (12) for dividing a cold-water flow, incoming from an existing service conduit (1), between a heater (7) for heating the cold water to a bactericidal temperature, and a heat exchanger (8) which has the purpose of cooling disinfected, hot water from the heater (7) to a temperature acceptable to the tissue of man, and wherein two outgoing conduits are connected with the heat exchanger, viz. a feeding conduit (15) for feeding disinfected water to the consumption unit and a drain conduit (16) which communicates with a drainage (6) for evacuation of cooling water, which has served its time, from the heat exchanger.

Abstract
The invention relates to an apparatus and a method for the disinfection of water for water consumption units (3) designed for health and dental care purposes. According to the invention, a cold-water flow is diverted from an existing service conduit (1), which via a main valve (12) is divided in a first part flow to a heater (7) in which the water is heated to a bactericidal temperature, as well as a second part flow to a heat exchanger (8) in which the cooling water cools the disinfected, hot water from the heater to a temperature acceptable to the tissue of man. From the heat exchanger (8), the disinfected, cooled water is fed to the consumption unit (3), and the cooling water that has served its time from the heat exchanger (8) is evacuated to a drainage (6).

- 8. Method for the disinfection of water intended for water consumption units (3) for health or dental care purposes, including the steps of diverting a cold-water flow from an existing service conduit (1) and via a main valve (12) dividing the same into a first part flow to a heater (7), in which the water is heated to a bactericidal temperature, as well as a second part flow to a heat exchanger (8) in which the cold water cools the disinfected, hot water from the heater to a temperature acceptable to the tissue of man, and of feeding from the heat exchanger (8) the disinfected, cooled water to the consumption unit (3), as well as cooling water, which has served its time, from the heat exchanger (8) to a drainage (6).
