Description

  The invention relates to a room ventilation system as specified in the introduction of claim 1.

  Food can be classified into two large classes: filter hoods and extract hoods.

  Compared with the filter hood, the extraction hood has a feature of discharging gas from the room in which the hood is installed.

  Specifically, in the structure of the extraction hood, air is extracted by an electric fan located on the upper surface of the range table, the air flows through the filter system, and is discharged outside through the duct.

  However, since these extraction hoods may require a masonry operation for installing the gas exhaust duct, they may not always be installed in existing rooms.

  In view of avoiding such drawbacks, filter hoods that achieve sufficient filtration efficiency exist in the prior art, but do not provide the gas treatment effect that can be achieved with an extraction hood.

  Also known are wall-mounted fans, that is, these types of fans that are capable of extracting gas from a room and discharging the gas to the outside.

  Specifically, these wall-mounted fans include an electric motor that drives the impeller so that air is discharged outside the room through a duct extending through the thickness of the wall or the thickness of a window glass or the like. ing.

  These wall-mounted fans require a low-load masonry operation that can be easily performed by unskilled persons.

  Furthermore, the extraction efficiency of these fans is equivalent to the extraction efficiency obtained by the extraction hood.

  Nevertheless, the hood and fan described above are stand-alone devices, i.e. devices designed for autonomous operation.

  Therefore, the user needs to understand the operation of the two separate devices and control the two devices according to specific requirements, with obvious and imaginable results.

  One of the objects of the present invention is to provide a ventilation system for a room, for example, a kitchen, capable of efficiently filtering substances contained in gas generated from food preparation / cooking.

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

  Another role of the present invention is to provide a room ventilation system that is inexpensive and readily available to the user.

  In accordance with the present invention, these and other objects are, as will be more fully understood below, a room having a feature with a filter hood and a wall fan as defined by the features of claim 1. Achieved by ventilation system.

  The accompanying drawings illustrate exemplary embodiments of the present disclosure and are intended to be illustrative and not limiting.

1 shows a perspective view of a room ventilation system according to the present invention. FIG. 2 shows a block diagram of the ventilation system of FIG.

  Referring to the accompanying drawings, the present disclosure relates to a ventilation system 1 for a room 2 comprising a home hood 3 disposed in the room, specifically a filter hood, and a walled fan 4 disposed in the room. .

  The room 2 may be, for example, a home kitchen or a public space such as a coffee bar or a restaurant.

As used herein, the term filter hood 3 is
Extract the gas in the room,
Filter the gas and
When the gas is filtered, it refers to a device having a structure that includes the devices necessary to reintroduce the gas into the room.

  Specifically, the filter hood 3 includes control means 3A that is appropriately controlled so as to change the operation state of the filter hood 3.

  For example, the control means 3A is switched from the on state (the hood extracts the gas, filters the gas, and when the gas is filtered, the gas is reintroduced into the room) to the off state or from the off state In addition, a specific function of the hood 3 and / or the switch may be activated.

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

  In other cases, the switch may be controlled manually.

The term walled fan 4 as used herein is
Extract the gas in the room,
For example, an apparatus having a structure including an apparatus necessary for exhausting gas from a room through an appropriate exhaust duct extending through a thickness such as an outer wall of the room 2 or a window glass of the room 2.

  Specifically, the wall-mounted fan 4 includes control means 4A that is appropriately controlled so as to change the operation state of the fan 4.

  For example, the control means 4A may change the fan from an on state (a fan extracts gas from the room 2 and exhausts gas from the room 2 or vice versa) to an off state or from an off state to an on state. 4 is configured to switch.

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

  It should be noted that the walled fan 4 may be reversible, that is, configured to draw air from outside and introduce the air into the room 2.

  For reversible operation, a suitable filter 4B is provided to filter incoming air, eg HEPA.

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

  For example, the plurality of converters 5 include converters (or sensors) that can detect temperature, humidity, smoke, odor, and the like.

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

  The ventilation system 1 includes processing and control means 6 in signal communication with a plurality of converters 5.

  The processing and control means 6 is preferably electrically connected to the plurality of converters 5, for example by electrical cable connection.

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

  The processing and control means 6 includes a memory 6A including firmware.

  Firmware includes one or more algorithms, i.e., operating sequences, encoded with appropriate program code and developed to accomplish a specific task as described in more detail below. It is out.

  These processing and control means 6 need to receive a plurality of values of characteristic parameters detected by a plurality of converters 5, process such values and activate only the hood 3, only the fan 4 or both. And the operation time of the fan 4 and / or the hood 3 is determined.

  The processing and control means 6 is in signal communication with an electric signal S1 that can be transmitted via a cable or radio frequency using the control means 3A of the hood 3.

  Specifically, the value of the characteristic parameter detected by the converter 5 can be evaluated with respect to an appropriate threshold value Vth by an algorithm implemented in firmware. This comparison provides the on time (or on time interval) of the fan 4 and / or the hood 3.

  For this purpose, the hood 3 is configured to be in signal communication with the wall-mounted fan 4 via a cable or radio frequency transmitter module included in the hood 3 and to transmit a signal S2 via the cable or radio frequency. Has been.

  The wall mounted fan 4 includes a first cable or radio frequency receiver module 4C configured to receive the cable signal S2 or the radio frequency signal S2 generated by the transmitter module 3B of the hood 3. Is advantageous.

  Specifically, the cable or radio frequency signal S2 is fed to the hood 3 so as to control the control means 4A when one or more of the aforementioned characteristic parameters detected by the converter 5 exceeds a respective predetermined threshold value Vth. Caused by.

  In other words, the signal S2 is generated according to the information content of the signal S1 generated by the processing and control means 6.

  Therefore, the signal S2 represents the on / off information of the fan 4 and the information regarding the on-time interval T1 of the walled fan 4 and / or the hood 3.

  It should be noted that the on-time T1 of the fan 4 is determined by the processing and control means 6 that processes the value detected by the converter 5.

  In other words, if the converter 5 evaluates that one or more characteristic parameters exceed the respective threshold, the processing and control means 6 activates the control means 3A and controls the control means 3A based on the firmware algorithm. Instructs the transmitter module of the hood 3 to generate the signal S2. This signal S2 is received by the receiving means 4C of the fan 4, and the control means 4A switches on the fan 4 at time T1. For example, when the converter detects an odor, the processing and control means 6 determines an on-time interval of the fan 4 based on a firmware algorithm and instructs the control means 3A of the hood 3 to be activated. Then, the control means 3A instructs the transmitter module of the hood 3 to generate the signal S2. This signal S2 is received by the receiving means 4C of the fan 4, and the control means 4A switches on the fan 4 at time T1.

  If the value detected by the converter 5 is below the respective predetermined threshold, the control means 6 commands the control means 3A of the hood 3 to generate the signal S2 and stop the fan 4.

  However, when the value of the characteristic parameter (such as odor, odor and smoke, or smoke and temperature, or any combination of smoke, odor and temperature) detected by the converter 5 exceeds one or more of the respective threshold values In addition to the activation of the fan 4, the firmware of the control means 6 instructs the control means 3A to activate the filter hood 3 and maintain the filter hood in this state for a predetermined on-time T2.

  With such a configuration, the filter hood 3 and the walled fan 4 are involved in the filtration and extraction functions so as to maximize efficiency in terms of comfort, consumption and air quality.

  The on-time T2 is determined again by the processing and control means 6 for processing the value detected by the converter 5.

  It should be noted that the on time T1 of the fan 4 may be different from the on time T2 of the hood 3.

  In the ventilation system of the invention, the hood 3 has the advantage of functioning as a fan 4 and / or a hub or processing center for the hood on / off signal.

  Furthermore, the ventilation system of the present invention does not require the user to separately control the filter hood 3 and walled fan 4 for room 2 gas filtration and extraction, but either or both of these (ie, , Only the fan 4, only the filter hood 3, or both the hood 3 and the fan 4), as detected by the converter 5, depending on the specific conditions of the gas in the room 2, respectively at predetermined intervals T1 and T2, Operate.

  According to a preferred embodiment, one or more or all of the plurality of converters 5 are arranged inside and / or outside the hood 3, inside the walled fan 4 and / or treatment and control means 6 and / or Can be arranged on the outside, which means that each part may be separated from and / or incorporated in the respective body of the fan 4, the hood 3 or the processing and control means 6 To do.

  Also, as shown in FIGS. 1 and 2, the processing and control means 6 can be arranged as a remote or built-in device with respect to the body of the hood 3, the fan 4 and / or the range base 7.

  When the processing and control means 6 are arranged away from the main body of the hood 3, these processing and control means 6 are configured to transmit a signal S1, ie a radio frequency signal, to the control means 3A of the hood 3. A radio frequency transmitter module 6B may be provided.

  For this purpose, the hood 3 comprises a radio frequency receiver module 3C configured to receive such a second radio frequency signal S1.

  This radio frequency signal S1 is always generated by the processing and control means 6 so as to control the change of the operating state of the hood 3 when one or more of the above-mentioned detected characteristic parameters exceeds respective predetermined thresholds. .

  According to a preferred embodiment, the radio frequency transmitter modules 3B, 3C, 4B and 6B are compliant with standards such as Bluetooth®, IR, Zigbee® standards and the like.

  Those skilled in the art will clearly recognize that many modifications and variations can be made to the above-described configurations to meet incidental and specific needs. All of these variations and modifications fall within the scope of the invention as defined in the following claims.
