DESCRIPTION

One-room ventilation system Technical field

The present invention relates to a ventilation system for a room as defined in the preamble of claim 1.

Background

The bells can be divided into two large classes: filter hoods and extractor hoods.

In comparison with the filter hoods, the extractor hoods have the characteristic of expelling gases from the room in which the hood is installed.

Particularly, in extractor hood designs, the air is extracted by an electric fan located on the cooking surface, flows through a filter system and is finally expelled out of the room through a duct.

However, these extractor hoods cannot always be installed in existing rooms, as they may require masonry work for the installation of exhaust ducts.

In order to avoid this inconvenience, there are filter hoods in the art that have achieved satisfactory filtration efficiency, but do not provide the gas treatment results that can be achieved with the extractor hoods.

Wall fans are also known, that is, those types of fans that can extract gases from a room and expel them outside.

Particularly, these wall fans include an electric motor that activates an impeller such that air is expelled out of the room through a conduit that extends through the thickness of the wall or the thickness of a window pane. or similar.

These wall fans require low impact masonry work, which can easily be done by unskilled personnel.

In addition, the extraction efficiency of these fans is comparable to that obtained by an extractor hood.

However, hoods and fans such as those described above are autonomous devices, that is, designed for autonomous operation. Patent document JP-A-2010145065 describes an exemplary hood combined with a wall fan.

Therefore, it is necessary for the user to learn the operation of two different devices, and control two devices according to particular requirements, which will imply obvious and imaginable consequences.

An 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 food preparation / cooking and the like.

A task of the present invention is to provide a ventilation system for a room that does not require expensive masonry work for its installation.

Another task of the present invention is to provide a ventilation system for a room that has a low cost and can easily be used by the user.

According to the present invention, these and other objects, as will be better understood below, are achieved by a ventilation system for a room that has the characteristic that it comprises a filter hood and a wall fan as defined by the characteristics of claim 1.

Detailed description

Referring to the attached figures, the present invention relates to 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 said room.

Room 2 can be, for example, the kitchen of a house or a public space, such as a cafeteria, a restaurant and the like.

As used herein, the term "filter hood 3" will designate an apparatus that has a frame containing the necessary devices to:

- extract the gases from the room,

- filter them and

- reintroduce them into the room, once they have been filtered.

Particularly, the filter bell 3 comprises control means 3A that are suitably controlled to change the operating state of the filter bell 3.

For example, the control means 3A can activate particular characteristics of the hood 3 and / or change from an ON state (in which the hood extracts the gases, filters them and reintroduces them into the room, once they have been filtered) to an OFF state, or vice versa.

For example, the control means 3A consists of an electrically controllable switch.

Otherwise, the switch can be controlled manually.

As used herein, the term wall fan 4 will designate an apparatus that has a frame containing the necessary devices for:

- extract the gases from the room,

- expel them out of the room through an appropriate ejection duct that extends, for example, through the thickness of a perimeter wall of room 2 or a window pane or the like of room 2.

Particularly, the wall fan 4 comprises control means 4A that are suitably controlled to change the operating state of the fan 4.

For example, the control means 4A are configured to change the fan 4 from an ON state (in which the fan extracts the gases from room 2 and expels them from room 2, or vice versa) to an ApAgAdO state or vice versa.

For example, the control means 4A consist of an electrically controllable switch.

It will be noted that the wall fan 4 can also be of the reversible type, that is, adapted to extract air from the outside and introduce it into room 2.

In case of reversible operation, an appropriate filter 4B is provided to filter the incoming air, for example, a HEPA.

The ventilation system 1 comprises a plurality of transducers 5, which are configured to detect a respective plurality of characteristic parameters of the gases in said room 2.

For example, the plurality of transducers 5 comprises transducers (or sensors) capable of detecting temperature, humidity, smoke, odors and the like.

These transducers are of known type and will not be described in detail.

The ventilation system 1 comprises processing and control means 6, which are in signal communication with the plurality of transducers 5.

Preferably, the processing and control means 6 are electrically connected to the plurality of transducers 5, for example, by means of a cable connection.

For example, 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 containing firmware.

The firmware comprises one or more algorithms, that is, sequences of operations encoded by an appropriate program code and developed to perform 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 detected by the plurality of transducers 5 and to process said values to determine whether the bell 3 alone, the fan 4 alone or both have to be operated, and the operating time of the fan 4 and / or the hood 3.

The processing and control means 6 are also in signal communication through an electrical signal S1 that can be transmitted by cable or by radio frequency using the control means 3A of the bell 3.

Particularly, the algorithms implemented in the firmware allow the values of the characteristic parameters detected by the transducers 5 to be evaluated with respect to suitable Vth threshold values. This comparison provides ON times (or ON intervals) for fan 4 and / or hood 3.

For this purpose, the bell 3 is in signal communication with the wall fan 4 through a cable or a radiofrequency transmitter module 3B included in said bell 3, and configured to transmit an S2 signal by cable or radiofrequency.

Advantageously, the wall fan 4 comprises a first radio frequency cable or 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 bell 3.

The radiofrequency cable or signal S2 is generated particularly by the bell 3 to control the control means 4A when one or more of said characteristic parameters detected by the transducers 5 exceed a respective predetermined threshold value Vth.

In other words, the signal S2 is generated according to the information contents of the signal S1 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 on the activation interval T1 for the wall fan 4 and / or the hood 3.

It should be taken into account that the ON time T1 for the fan 4 is determined by the processing and control means 6, which process the values detected by the transducers 5.

In other words, when the transducers 5 evaluate that one or more characteristic parameters exceed the respective threshold values, the processing and control means 6, based on firmware algorithms, actuate the control means 3A, which in turn give instructions to the transmitter module of bell 3 to emit the S2 signal. This signal S2 is received by the receiving means 4C of the fan 4, such that the control means 4A turn on the fan 4 during the period of time T1. For example, if the transducers detect odors, the processing and control means 6, based on firmware algorithms, determine the ON time interval for the fan 4 and give instructions to turn on the control means 3A of the bell 3. The latter in turn give instructions to the transmitter module of bell 3 to emit the S2 signal. This signal S2 is received by the receiving means 4C of the fan 4, such that the control means 4A turn on the fan 4 during the period of time T1.

When the values detected by the transducers 5 fall below their respective predetermined threshold values, the control means 6 instructs the control means 3A of the bell 3 to emit the signal S2 to turn off the fan 4.

However, when the values of the characteristic parameters detected by transducers 5 (such as odors, odors and smoke, or smoke and temperature, or any combination of smoke, smell and temperature) exceed one or more of their respective threshold values, in addition If the fan 4 is switched on, the firmware of the control means 6 can also instruct the control means 3A to turn on the hood of the filter 3 and keep it in this state for a predetermined time of T2 ON.

Through this arrangement, the filter hood 3 and the wall fan 4 will combine their filtering and extraction characteristics to maximize operating efficiency in terms of comfort, consumption and air quality.

Again, the ON time T2 is determined by the processing and control means 6, which process the values detected by the transducers 5.

It should be noted that the ON time T1 for fan 4 may differ in duration from the ON time T2 for bell 3.

Advantageously, with the current ventilation system, the hood 3 will act as a concentrator or handling center for the ON / OFF signals for the fan 4 and / or the hood.

In addition, with the current ventilation system, the user does not need to control the filter hood 3 and the wall fan 4 separately for filtering and extracting the gases in room 2, but one or both (i.e. only the fan 4, only the filter hood 3 or both, the hood 3 and the fan 4) will be operated for the respective predetermined intervals T1, T2 according to the particular conditions of the gases in room 2, as detected by the transducers 5.

According to the preferred embodiments, one, more or all of the plurality of transducers 5 can 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 can be placed remotely with respect to, 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, can also be arranged as a remote device or incorporated with respect to the frames of the hood 3, the fan 4 and / or a kitchen 7.

If the processing and control means 6 are located away from the frame of the hood 3, then these processing and control means 6 may comprise a radio frequency transmitter module 6B that is configured to transmit the signal S1, that is, a radio frequency signal to control means 3A of bell 3.

For this purpose, the bell 3 comprises a radio frequency receiver module 3C, which is configured to receive said second radio frequency signal S1.

This radio frequency signal S1 is always generated by the control and processing means 6 to control the change of the operating states of the bell 3 when one or more of said characteristic parameters detected exceed the respective predetermined threshold values.

According to a preferred embodiment, the radio frequency transmitter modules 3B, 3C, 4B and 6B meet the specifications of the Bluetooth, IR, Zigbee or similar standards.

It will be apparent to those skilled in the art that a series of changes and variants can be made to the arrangements described above to meet the specific and incidental needs. All of these variants and changes fall within the scope of the invention, as defined in the following claims.
