Sanitation compartment for recovering the heat from hot wastewater during bathing

Abstract

A sanitation compartment capable of preheating the clean, cold water from the mains, for use in the bath, using, residual heat present in wastewater. The water used in the bath is collected from the cabinet, passing via the drain and is conveyed to the collector vessel and transferred to a heat exchanger. Clean, cold water from the mains circulates through the heat exchanger, where it is preheated on receiving heat from the wastewater present within the collector vessel.

Description

FIELD OF APPLICATION[0001]The invention relates to the field of application of goods connected with civil construction, its aim being the utilization of the heat from wastewater for preheating the clean, cold water from the mains for use in bathing, providing a substantial saving in terms of the thermal energy required by the heater of the installation in order to obtain the required use temperature, by means of elements that are easy to clean and to maintain.PRIOR ART[0002]A number of systems currently exist that reutilize the heat of water dispensed by a shower, as is the case of the patent documents listed below, which, however, owing to one or more of the following design defects, do not even make it as far as production: structural complexity, high production costs, low efficiency, deficient ergonomics, maintenance problems, etc.[0003]Patent document MU 6601585, filed on 5 Sep. 1986, entitled “Compartment for bath with heat regeneration”, teaches a unit that aims to regenerate ...

AI Technical Summary

Benefits of technology

The present invention is a sanitation compartment that can save energy by preheating clean, cold water from the mains before sending it to a through-heater or mixing it with hot water to adjust its temperature. This results in a reduction of thermal energy consumed to achieve the required bathing temperature.

Problems solved by technology

A number of systems currently exist that reutilize the heat of water dispensed by a shower, as is the case of the patent documents listed below, which, however, owing to one or more of the following design defects, do not even make it as far as production: structural complexity, high production costs, low efficiency, deficient ergonomics, maintenance problems, etc.

As may be seen, and as is known especially to those skilled in the art, such systems are very limited in terms of practical application, either on account of their structural complexity and consequent high production cost, through the need for pressurizers to guarantee a satisfactory heat exchange, with no provision for cleaning and maintenance resources, or, furthermore, owing to the problems involved in their installation.

Evidence of this is the fact that such devices have never entered production.
