Description

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

State of the art

Hoods used in ventilation systems can be divided into two large classes: hoods with a filter and hoods. Exhaust hoods, compared to hoods equipped with a filter, have the ability to draw gases from the room in which the hood hood is installed.

In particular, in exhaust hood designs, air is drawn out using an electric fan located above the hob, passes through a filter system and, ultimately, is thrown out of the room through the exhaust duct.

However, such exhaust hoods may not always be installed in the rooms used, since for the construction of a gas outlet channel, it may be necessary to carry out wall masonry work.

To eliminate this drawback in the prior art, hoods with a filter are known that have achieved satisfactory filtration efficiency, but do not provide gas cleaning results that can be achieved by using hoods.

Wall fans are known, i.e. those types of fans that can draw gases from the room and throw them out.

Wall fans, in particular, are equipped with electric motors that drive the fan impeller so that air is removed from the room through a channel that passes through a wall thickness or a thickness of a window glass, frame, and the like.

For such wall fans, it is necessary to carry out work with small violations of the masonry wall. Such work can be easily performed by unskilled personnel.

In addition, the efficiency of the hood with these fans is comparable to that achieved with the hood.

The hoods and fans described above are autonomous devices, i.e. designed for autonomous functioning.

Thus, the user needs to study the operation of two separate devices and adjust them in accordance with certain requirements, which will include explicit and imaginary sequences of operations.

One objective of the present invention is to provide a ventilation system of a room, in particular a kitchen, which allows efficiently filtering substances contained in the gases that are released during cooking / cooking food, etc.

One object of the present invention is to provide a room ventilation system for the installation of which it is not necessary to carry out expensive work with masonry walls.

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

In accordance with the present invention, these and other objectives are achieved, as is more clearly described below, using a room ventilation system, which is characterized by the fact that it contains a hood with a filter and a wall fan, as defined by the characteristics of claim 1 of the formula.

Brief Description of the Drawings

The accompanying drawings show illustrative, non-limiting examples of embodiments of the present invention.

FIG. 1 is a perspective view of a room ventilation system in accordance with the present invention.

FIG. 2 is a block diagram of the ventilation system of FIG. one.

Detailed description

In accordance with the accompanying drawings, the present invention relates to a ventilation system 1 of a room 2, comprising a hood 3 for domestic use, preferably a hood with a filter located in the room, and a wall fan 4 also installed in this room. Room 2 can be a kitchen at home or a public room, such as a small cafe, restaurant, etc.

As used herein, the term “extractor 3 with a filter” will mean a device comprising a housing in which the means necessary for extracting gases present in the room, filtering them and re-supplying them to the room immediately after filtering are located.

In particular, the exhaust hood 3 with the filter contains control means 3A, which are suitably adjusted to change the operating position of the hood 3 with the filter.

For example, the means for regulating can actuate certain elements of the hood 3 and / or switch it from the ON position (in which the hood draws in gases, filters them and re-enters the room immediately after filtering) to the ON position or vice versa.

For example, the control means 3A includes an electrically adjustable switch.

- 1 028757

In other cases, a manual switch may be used.

As used herein, the term “wall fan 4” will mean a device comprising a housing in which the means necessary for suction of gases in a room are located;

ejecting them from the room through the corresponding exhaust channel, which passes, for example, through the thickness of the outer wall of the room 2 or window glass, or a similar element of the room

2.

In particular, the wall fan 4 comprises control means 4A that are suitably adjusted to change the operating position of the fan 4.

For example, these control means 4A are configured to switch the fan 4 from the ON position (in which the fan draws in gases from the room 2 and expels them from the room 2, or vice versa) to the OFF position or vice versa.

For example, the control means 4A includes an electrically adjustable switch.

It should be noted that the wall fan 4 may be of a reversible type, i.e. adapted for air intake from the outside and entering it into the room 2.

In the case of a reversed fan, a suitable 4V filter is used to filter the incoming air, for example an HEPA filter.

The ventilation system 1 contains a number of converters 5, which are configured to determine the corresponding series of gas parameters in room 2.

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

These converters are converters of a known type and will not be described in detail here.

The ventilation system 1 contains a means of processing and regulation 6, which are connected by signals with the specified number of converters 5.

Preferably, the processing and control means 6 are electrically connected to a series of transducers 5, for example, by wire communication.

For example, the processing and regulation means 6 include an electronic processing device, such as a microcontroller.

Means 6 processing and regulation contains a storage device 6A with software.

The software includes one or more algorithms, i.e. the sequences of operations encoded by the appropriate program code and created to perform certain tasks, described in more detail below.

These processing and regulation means 6 are configured to receive values of a number of characteristic parameters detected by the indicated series of converters 5 and to process these values in order to decide whether only hood 3 or only the fan will be activated or both of these means will be activated, and to determine the duration of operation fan 4 and / or hood 3.

Means 6 of the processing and regulation, in addition, are connected by signals through an electrical signal 81, which can be transmitted using a cable or radio frequency, using means for regulation intended for drawing 3.

In particular, the algorithms introduced into the software provide a comparison of the values of the characteristic parameters determined by the transducers 5 with the corresponding threshold values V of these parameters. The comparison results allow you to determine the periods of time in the ON position (or time periods for the ON position) of the fan 4 and / or hood 3.

For this purpose, the hood 3 is connected by signals to the wall fan 4 using a cable or the module 3B transmitter of the radio frequency signal integrated in such a hood 3, and is configured to transmit the signal 82 via cable or radio frequency.

Preferably, the wall fan 4 is provided with a first cable or radio frequency receiver module 4C, which is configured to receive a signal 82 transmitted through the cable and generated by the transmitter module 3B mounted in the hood 3.

The signal 82 transmitted through the cable or the radio frequency signal is generated, in particular, by drawing 3 to activate the regulation means 4A if one or more of these characteristic parameters detected by the transducers 5 exceeds a corresponding predetermined threshold value V of the parameter.

In other words, the signal 82 is generated in accordance with the information contained in the signal 81 generated by the processing and regulation means 6. In this case, the specified signal 82 gives information regarding the ON / OFF positions for the fan 4, and information regarding the interval T1 of the time spent in the ON position of the wall fan 4 and / or hood 3.

It should be noted that the interval T1 of the time the fan 4 is in the ON position is determined using processing and regulation means 6, which process the values detected by converters 5.

In other words, if the transducers 5 show that the value of one or more characteristic parameters exceeds the corresponding threshold values, the processing and regulation means 6 are activated based on the software algorithms of the regulation means 3A, which, in turn, give an instruction to the transmitter module extractors 3 generate a signal 82. This signal 82 is received by the receiving means 4C provided with the fan 4, as a result of which the regulating means 4A switch the fan 4A for the period T1 is on. For example, if the transmitters 5 determine the presence of odors, the processing and control means 6, based on the software algorithms, set the time interval for the fan 4 to be in the ON position and give a command to turn on the means for regulating the hood 3. The latter, in turn, sends a command to the hood 3 to generate a signal 82. This signal 82 is received by the receiving means 4C provided with the fan 4, after which the regulating means 4A switch the fan 4 for a period of time T1 to ON

If the value (s) determined by the converters 5 decreases below the predetermined corresponding threshold values, the control means 6 command the control means 3A of the hood 3 to generate a signal 4 to turn off the fan 4.

However, if the characteristic values determined by the transducers 5 (such as odors, smells and smoke, or smoke and temperature) exceed one or more of the corresponding threshold values, in addition to turning on the fan 4, the software of the control means 6 may also give a command to the control means FOR turning on the hood 3 with the filter and holding it in this ON position for a predetermined period of time.

With this arrangement, hood 3 with a filter and fan 4 will combine their inherent filtering characteristics and hoods to achieve maximum performance in terms of comfort, energy consumption and air quality.

Again, the time T2 for the ON position is determined using the processing and regulation means 6, which process the parameter values detected by the transducers 5.

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

Preferably, when using the ventilation system in accordance with the present invention, the hood 3 will function as a center for transmitting or processing ON / OFF signals generated to control the fan 4 and / or the hood 3.

In addition, the proposed ventilation system eliminates the need for the user to separately control the operation of the exhaust hood 3 with a filter and the wall fan 4 for filtering and drawing gases from room 2, since either one of them or both (i.e. only fan 4 or only exhaust 3 s filter, or both - fan 4 and exhaust hood 3 with filter at the same time) will be used for the corresponding predefined time intervals T1 and T2 in accordance with the specific parameters of the gas present in the room 2 Defined by the transducers 5.

According to preferred embodiments, one or more or all of the series of converters 5 can be installed outside and / or inside the hood 3, the wall fan 4 and / or the processing and regulation means 6. This means that they can be located at a distance from and / or attached to each respective casing of the fan 4, hood 3 or means 6 processing and regulation.

Said processing and control means 6 shown in FIG. 1 and 2, can also be placed away from the hood 3, fan 4 and / or hob 7, or they can be elements integrated into the housings.

If the processing and regulation means 6 are located at a distance from the hood 3, then the processing and regulation means 6 may include an RF transmitter module 6B that is configured to transmit a signal 81, i.e. RF signal, means 3A regulation, which is equipped with a hood 3.

For this purpose, the hood 3 is provided with a radio frequency signal receiver module 3C, which is configured to receive such a second radio frequency signal 81.

The specified RF signal 81 is generated by means of processing and regulation 6 to regulate changes in the operating position of the hood 3 always if one or more of these characteristic parameters exceeds the corresponding predefined values.

According to a preferred embodiment, the modules 3B, 3C, 4B and 6B of the radio frequency transmitter satisfy the technical characteristics of the Βΐιιοίοοίΐι systems. ΙΚ, Ζφφθθ, etc.

Those skilled in the art will of course appreciate that, with respect to the embodiments described above, a number of changes and variations can be made to meet additional and specific requirements. All of these changes and variations are within the scope of the invention defined by the following claims.
