Ventilation system for a room

Abstract

The present invention relates to a ventilation system for a room which comprises a hood for domestic use located in said room, a wall fan located in said room, a plurality of transducers configured to detect a respective plurality of characteristic parameters of the gases in said room; processing and control means in signal communication with said plurality of transducers and in signal communication with said first control means, processing and control means electrically connected with said plurality of transducers and in signal communication with said first control means, said processing and control means comprising firmware configured to process said detected characteristic parameters and to transmit a first control signal to control said hood for domestic use. The characterizing feature is that said hood for domestic use is in signal communication with said wall fan via a first transmitter module, located in said hood, and configured to transmit a second signal, said wall fan comprising a first receiver module configured to receive said second signal; said second radio frequency signal being generated by said hood according to said first signal to instruct said second control means to turn on said wall fan and keep it in this state for a first predetermined ON-time when one or more of said characteristic parameters detected by said plurality of sensors exceed respective predetermined threshold values.

Description

TECHNICAL FIELD[0001]The present invention relates to a ventilation system for a room as defined in the preamble of claim 1.BACKGROUND ART[0002]Hoods can be divided into two large classes: filter hoods and extractor hoods.[0003]As compared with filter hoods, extractor hoods have the characteristic of exhausting gases from the room in which the hood is installed.[0004]Particularly, in extractor hood designs, air is extracted by an electric fan located above the cooktop, flows through a filter system and is finally exhausted out of the room through a duct.[0005]Nevertheless, these extractor hoods may not always be installed in existing rooms, as they may require masonry works for gas exhaust duct installation.[0006]In view of obviating this drawback, filter hoods exist in the art which have achieved satisfactory filtering efficiency, but do not provide the gas treatment results that may be achieved with extractor hoods.[0007]Wall fans are also known, i.e. those types of fans that can ...

Problems solved by technology

Nevertheless, these extractor hoods may not always be installed in existing rooms, as they may require masonry works for gas exhaust duct installation.

In view of obviating this drawback, filter hoods exist in the art which have achieved satisfactory filtering efficiency, but do not provide the gas treatment results that may be achieved with extractor hoods.

These wall fans require low-impact masonry works, that may be easily carried out by unskilled personnel.

Therefore, the user is required to learn the operation of two distinct apparatuses, and control two devices according to particular requirements, which will involve obvious and imaginable consequences.
