Definitions

  • the present invention relates to a ventilation system for a room as defined in the preamble of claim 1 .
  • Hoods can be divided into two large classes: filter hoods and extractor hoods.
  • extractor hoods As compared with filter hoods, extractor hoods have the characteristic of exhausting gases from the room in which the hood is installed.
  • 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.
  • 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.
  • Wall fans are also known, i.e. those types of fans that can extract gases from a room and exhaust them outside.
  • these wall fans include an electric motor that drives an impeller such that air is exhausted out of the room through a duct that extends through the thickness of the wall or the thickness of a window pane or the like.
  • hoods and fans as described above are stand-alone devices, i.e. designed for autonomous operation.
  • One object of the present invention is to provide a ventilation system for a room, such as a kitchen, that allows efficient filtering of the substances contained in the gases derived from preparation/cooking of food and the like.
  • One task of the present invention is to provide a ventilation system for a room that does not require costly masonry works for installation.
  • Another task of the present invention is to provide a ventilation system for a room that has a low cost and may be easily used by the user.
  • a ventilation system for a room that has the characteristic of comprising a filter hood and a wall fan as defined by the features of claim 1 .

  • FIG. 2 shows a block diagram of the ventilation system of FIG. 1 .
  • a ventilation system 1 for a room 2 comprising a hood for domestic use 3 , preferably a filter hood, located in the room, and a wall fan 4 , also located in such room.
  • the room 2 may be, for example, the kitchen of a home or a public space, such as a coffee bar, a restaurant, and the like.
  • filter hood 3 will designate an apparatus having a frame that contains the devices required for:
  • the filter hood 3 comprises control means 3 A that are suitably controlled to change the operating state of the filter hood 3 .
  • control means 3 A may actuate particular features of the hood 3 and/or switch from an ON state (in which the hood extracts gases, filters them and reintroduces them into the room, once they have been filtered) to an OFF state, or vice versa.
  • control means 3 A consist of an electrically controllable switch.
  • the switch may be manually controlled.
  • wall fan 4 will designate an apparatus having a frame that contains the devices required for:
  • an appropriate exhaust duct which extends, for instance, through the thickness of a perimeter wall of the room 2 or a window pane or the like of the room 2 .
  • the wall fan 4 comprises control means 4 A that are suitably controlled to change the operating state of the fan 4 .
  • control means 4 A are configured to switch the fan 4 from an ON state (in which the fan extracts gases from the room 2 and exhausts them out of the room 2 , or vice versa) to an OFF state or vice versa.
  • control means 4 A consist of an electrically controllable switch.
  • the wall fan 4 may also be of reversible type, i.e. adapted to withdraw air from outside and introduce it into the room 2 .
  • an appropriate filter 4 B is provided to filter the incoming air, e.g, a HEPA.
  • the ventilation system 1 comprises a plurality of transducers 5 , which are configured to detect a respective plurality of characteristic parameters of gases in said room 2 .
  • the plurality of transducers 5 comprises transducers (or sensors) able to detect temperature, humidity, smoke, odors and the like.
  • the ventilation system 1 comprises processing and control means 6 , which are in signal communication with the plurality of transducers 5 .
  • the processing and control means 6 are electrically connected with the plurality of transducers 5 , e.g. by means of a cable connection.
  • the processing and control means 6 consist of an electronic processing device such as a microcontroller.
  • the processing and control means 6 comprise a memory 6 A which contains firmware.
  • the firmware comprises one or more algorithms, i.e. sequences of operations coded by an appropriate program code and developed to accomplish particular tasks, as described in greater detail below.
  • These processing and control means 6 are configured to receive the values of the plurality of characteristic parameters as detected by the plurality of transducers 5 and to process such values to determine whether the hood 3 only, the fan 4 only or both have to be actuated, and the operating time of the fan 4 and/or the hood 3 .
  • the processing and control means 6 are also in signal communication via an electric signal S 1 that can be transmitted via cable or radio frequency using the control means 3 A of the hood 3 .
  • the algorithms implemented in the firmware allow the values of the characteristic parameters as detected by the transducers 5 to be assessed against appropriate threshold values Vth. This comparison provides ON-times (or ON-time intervals) for the fan 4 and/or the hood 3 .
  • the hood 3 is in signal communication with the wall fan 4 via a cable or radio frequency transmitter module 3 B included in such hood 3 , and configured to transmit a signal S 2 via cable or radio frequency.
  • the wall fan 4 comprises a first cable or radio frequency receiver module 4 C, which is configured to receive the cable signal S 2 or the radio frequency signal S 2 generated by the transmitter module 3 B of the hood 3 .
  • the cable or radio frequency signal S 2 is particularly generated by the hood 3 to control the control means 4 A when one or more of said characteristic parameters as detected by the transducers 5 exceed a respective predetermined threshold value Vth.
  • the signal S 2 is generated according to the information contents in the signal S 1 generated by the processing and control means 6 .
  • the signal S 2 is representative of the ON/OFF information for the fan 4 and the information about the ON-time interval T 1 for the wall fan 4 and/or the hood 3 .
  • the ON-time T 1 for the fan 4 is determined by the processing and control means 6 , which process the values detected by the transducers 5 .
  • the processing and control means 6 when the transducers 5 assess that one or more characteristic parameters exceed respective threshold values, the processing and control means 6 , based on firmware algorithms, actuate the control means 3 A, which in turn instruct the transmitter module of the hood 3 to emit the signal S 2 .
  • This signal S 2 is received by the receiver means 4 C of the fan 4 , such that the control means 4 A switch the fan 4 on for the time period T 1 .
  • the processing and control means 6 determine the ON-time interval for the fan 4 and instruct to turn on the control means 3 A of the hood 3 . The latter instruct in turn the transmitter module of the hood 3 to emit the signal S 2 .
  • This signal S 2 is received by the receiver means 4 C of the fan 4 , such that the control means 4 A switch the fan 4 on for the time period T 1 .
  • control means 6 instruct the control means 3 A of the hood 3 to emit the signal S 2 to turn off the fan 4 .
  • the firmware of the control means 6 may also instruct the control means 3 A to turn on the filter hood 3 and keep it in this state for a predetermined ON-time T 2 .

  • the user is not required to separately control the filter hood 3 and the wall fan 4 for filtration and extraction of the gases in the room 2 , but either or both (i.e. the fan 4 only, the filter hood 3 only or both the hood 3 and the fan 4 ) will be actuated for respective predetermined intervals T 1 , T 2 according to the particular conditions of the gases in the room 2 , as detected by the transducers 5
  • one, more or all of the plurality of transducers 5 may be placed outside and/or inside the hood 3 , the wall fan 4 and/or the processing and control means 6 , which means that they may be placed remote from and/or incorporated in each respective frame of the fan 4 , the hood 3 or the processing and control means 6 .
  • the processing and control means 6 may be also disposed as a remote or built-in device relative to the frames of the hood 3 , the fan 4 and/or a cooktop 7 .
