Definitions
- Ventilation system for a room
- 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. 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. 1 shows a perspective view of the ventilation system for a room according to the present invention
- FIG. 1 shows a block diagram of the ventilation system of Figure 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 3A 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 3A 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:
- the wall fan 4 comprises control means 4A that are suitably controlled to change the operating state of the fan 4.
- control means 4A 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 4A 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 4B 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 6A 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 SI 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 3B included in such hood 3, and configured to transmit a signal S2 via cable or radio frequency.
- the wall fan 4 comprises a first cable or radio frequency receiver module 4C, which is configured to receive the cable signal S2 or the radio frequency signal S2 generated by the transmitter module 3B of the hood 3.
- the cable or radio frequency signal S2 is particularly generated by the hood 3 to control the control means 4A when one or more of said characteristic parameters as detected by the transducers 5 exceed a respective predetermined threshold value Vth.
- the signal S2 is generated according to the information contents in the signal S I generated by the processing and control means 6. Therefore, the signal S2 is representative of the ON/OFF information for the fan 4 and the information about the ON-time interval Tl for the wall fan 4 and/or the hood 3.
- the ON-time Tl 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 3A, which in turn instruct the transmitter module of the hood 3 to emit the signal S2.
- This signal S2 is received by the receiver means 4C of the fan 4, such that the control means 4A switch the fan 4 on for the time period Tl .
- the processing and control means 6, based on firmware algorithms 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 S2.
- This signal S2 is received by the receiver means 4C of the fan 4, such that the control means 4 A switch the fan 4 on for the time period Tl .
- control means 6 instruct the control means 3 A of the hood 3 to emit the signal S2 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 T2.
- the filter hood 3 and the wall fan 4 will join their filtration and extraction features for maximized operational efficiency in terms of comfort, consumption and air quality.
- ON-time T2 is determined by the processing and control means 6, which process the values detected by the transducers 5.
- the ON-time Tl for the fan 4 may differ in duration from the ON-time T2 for the hood 3.
- the hood 3 will act as a hub or handling center for the ON/OFF signals for the fan 4 and/or the hood.
- 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 Tl, T2 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, as shown in Figures 1 and 2, 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.
- these processing and control means 6 may comprise a radio frequency transmitter module 6B which is configured to transmit the signal S I, i.e. a radio frequency signal, to the control means 3 A of the hood 3.
- the hood 3 comprises a radio frequency receiver module 3C, which is configured to receive such second radio frequency signal SI .
- This radio frequency signal SI is always generated by the processing and control means 6 to control the change of the operating states of the hood 3 when one or more of said detected characteristic parameters exceed respective predetermined threshold values.
- the radio frequency transmitter modules 3B, 3C, 4B and 6B comply with the specifications of Bluetooth, IR, Zigbee standards or the like.
