Description

Technical Field

[0001] This invention relates to an artificial intelligence range hood, and more specifically, to an artificial intelligence range hood capable of selectively opening or closing movable intake and exhaust ducts or indoor polluted air intake and exhaust ducts, thereby enabling rapid and convenient removal of cooking fumes and indoor polluted air. Furthermore, since the fumes can be rapidly drawn in from a 360° direction through the fume inlet on the oil collection tray, the efficiency of intake and exhaust can be improved not only in confined spaces but also in spacious areas, and it can effectively prevent lung cancer caused by inhaling cooking fumes. Background Technology

[0002] Typically, a range hood system is a device installed during cooking to promptly remove air pollutants such as heat, cooking odors, smoke, dust, exhaust gases, and steam generated during the cooking process, thereby preventing indoor air pollution. As consumers become increasingly health-conscious, its popularity is also growing.

[0003] Existing range hood systems are typically installed at a certain distance above the stove (range), which serves as a heating device, to draw in cooking gases produced during the cooking process.

[0004] A stove is a device that uses gas or electricity to cook food; gas stoves or induction cookers are devices that use gas or electricity to cook food.

[0005] Induction cooktops use an indirect heating method that generates heat directly by inducing a magnetic field inside the heated object (such as a pot). Compared with gas stoves, this induction heating method can reduce indoor air pollution. Since the device itself generates almost no heat, it can prevent the indoor temperature from rising in the hot summer. In addition, since the cooktop itself is not heated, it can avoid the danger of burns caused by high temperatures. Its advantage of rapid cooking is particularly prominent, and therefore it has been widely adopted in recent years.

[0006] Typically, in large kitchens of restaurants, schools, and businesses where meat and fish are grilled, Chinese cuisine is prepared, and fried foods are prepared, large amounts of steam and cooking oil fumes are generated during the cooking process, leading to indoor air pollution. These steam and cooking fumes, produced when grilling or frying meat and fish, contain fats and fatty acids, amine-containing malodorous substances (the main component of fishy odor), ethanol used as a tenderizer, aromas released by various spices and seasonings, aromatic hydrocarbons (the main volatile components of odor), carcinogenic substances such as benzo[a]pyrene and formaldehyde generated during heating and carbonization, nitrogen oxides (NOx), carbon dioxide (CO2) produced from the combustion of carbon monoxide (CO), combustion residue (fly ash), and ultrafine dust, all mixed with air and water vapor to form a gas mixture.

[0007] It is evident that cooking fumes not only cause unpleasant odors but also have adverse effects on human health, thus requiring their removal. Consequently, the International Agency for Research on Cancer (IARC) has classified these fumes as carcinogenic. Furthermore, the government stipulates that kitchen workers who are chronically exposed to cooking fumes and develop lung cancer due to such exposure can be recognized as having suffered an occupational injury.

[0008] Existing range hood systems consist of an intake for drawing in cooking gases and a range hood body installed above the intake for expelling the cooking gases drawn in through the intake upwards.

[0009] The inlet is usually equipped with a filter or lighting device, and a blower is provided on one side of the inlet or the range hood body to smoothly draw in and expel cooking fumes.

[0010] However, existing range hood systems only draw in and exhaust cooking fumes from the top of the hood. As a result, the distance between the point where cooking fumes are generated and the point where they are drawn in and exhausted is relatively large, causing users to inhale cooking fumes and harm their health.

[0011] Furthermore, in existing range hood systems, most of the suction ducts are designed with a circular opening at the bottom, through which fumes are drawn in and expelled. This structure has a certain suction and exhaust efficiency in small spaces, but in more spacious environments, its suction and exhaust efficiency is significantly reduced, thus posing a potential risk of lung cancer caused by inhaling fumes. Summary of the Invention

[0012] Technical problems to be solved The present invention is proposed in view of the aforementioned problems, and its purpose is, firstly, to provide an artificial intelligence range hood that can selectively open or close movable intake and exhaust pipes or indoor polluted air intake and exhaust pipes, thereby quickly and conveniently expelling cooking fumes and indoor polluted air, and preventing occupational diseases such as lung cancer that may be caused by continuous inhalation of cooking fumes containing various harmful substances above a certain standard amount, while significantly improving indoor air quality and automatically creating a comfortable indoor air environment.

[0013] The second problem to be solved by the present invention is to provide an artificial intelligence range hood that, by lowering the movable intake and exhaust pipe to the position where cooking fumes are generated, can not only quickly draw in and exhaust cooking fumes, but also collect the cooking fumes from the side of the oil collection tray in a 360° direction into the fumes inlet, and then quickly exhaust them through the movable intake and exhaust pipe and the fixed intake and exhaust pipe in sequence, thereby effectively protecting the health of the operator.

[0014] The second problem to be solved by the present invention is that, thirdly, an artificial intelligence range hood is provided in which the control unit controls the operation of the emission mode switching device based on artificial intelligence, which can automatically exhaust cooking fumes or indoor polluted air, and after adjusting the position of the movable intake and exhaust pipe housing by automatically moving it up and down, it drives the range hood fan motor, thereby automatically and quickly exhausting cooking fumes. In addition, it can compare the concentration of various harmful substances detected by the harmful substance detection sensor with the various harmful substance benchmark values ​​stored in its internal storage, and control the speed (output) of the fan motor according to the comparison result.

[0015] The technical issues of this invention are not limited to those described above. For other technical issues not mentioned above, those skilled in the art can clearly understand them from the following description.

[0016] Technical solution To achieve the aforementioned objective, the artificial intelligence range hood of the present invention is characterized by comprising: a range hood body, comprising a range hood base plate having multiple fume inlets and a duct guide hole in the center, and an outer shell vertically mounted above the range hood base plate, the range hood body being located above a heating device; a fixed intake and exhaust duct, vertically fixedly mounted on the upper side inside the outer shell to guide the intake and exhaust of fumes and indoor polluted air generated during cooking; and a fan motor mounted on the upper part of the fixed intake and exhaust duct for forcibly drawing in the fumes and polluted air entering the fixed intake and exhaust duct. The system includes a duct for discharging cooking fumes and indoor polluted air to the outside; a movable intake and exhaust duct that can move up and down along the guide hole of the duct and draw in and exhaust cooking fumes during movement, and is movably installed at the lower part of the fixed intake and exhaust duct; a height adjustment module for adjusting the height of the movable intake and exhaust duct; an indoor polluted air intake and exhaust duct connected to the middle of the fixed intake and exhaust duct for guiding the intake and exhaust of indoor polluted air; and an emission mode switching device that can selectively open or close the movable intake and exhaust duct or the indoor polluted air intake and exhaust duct to achieve the discharge of cooking fumes and indoor polluted air.

[0017] In addition, the movable intake and exhaust pipe includes: a movable pipe shell for guiding the emission of oil fumes; an oil filter screen, replaceably installed on the movable pipe shell for filtering the grease contained in the oil fumes; and an oil collection tray, detachably installed on the lower side of the movable pipe shell, and having multiple oil fume inlets formed on its outer surface.

[0018] In addition, the height adjustment module includes: a winding motor that generates driving force; a winding roller mounted on the rotating shaft of the winding motor; and a winding wire that can be wound around the winding roller and fixed at its end to the movable intake and exhaust pipe. Using the power of the winding motor, the winding roller is rotated in the forward or reverse direction, thereby winding or releasing the winding wire around the outer circumference of the winding roller to adjust the vertical height of the movable intake and exhaust pipe.

[0019] In addition, the exhaust mode switching device includes: a baffle that can rotate about a hinge axis around the middle of the fixed intake and exhaust duct to selectively open or close the indoor polluted air intake and exhaust duct or the movable intake and exhaust duct; a baffle rotation motor that drives the baffle to rotate about the hinge axis; and a linkage bracket connecting the baffle and the hinge axis.

[0020] In addition, the fumes generated during cooking and entering the fume inlet will be filtered by the oil filter to remove the oil (oil vapor) and then discharged to the outside (atmosphere) through the pipe housing and the fixed intake and exhaust pipe.

[0021] In addition, cooking fumes that rise during cooking but fail to enter the fume inlet will first enter the filter screen of the fume inlet, and then be filtered by the oil filter to remove oil before being discharged to the outside (atmosphere) through the movable pipe housing and the fixed intake and exhaust pipe.

[0022] Furthermore, according to another embodiment of the present invention, the artificial intelligence range hood further includes: a sensor module, comprising a first sensor unit for detecting oil fumes and a second sensor unit for detecting indoor polluted air; and a control unit, receiving detection signal values ​​from the first sensor unit and the second sensor unit, and controlling the operation of the fan motor and the emission mode conversion device to selectively exhaust oil fumes or indoor polluted air.

[0023] The control unit uses the extracted data and calculated emission efficiency as learning data to control the operation of the emission mode conversion device based on artificial intelligence algorithms.

[0024] Furthermore, the sensor module further includes a third sensor unit for detecting the height of the cooking container. The control unit receives the signal value detected by the third sensor unit, causing the pipe housing of the movable intake and exhaust pipe to move up and down automatically and adjust its position, and then drives the fan motor to achieve the intake and exhaust of oil fumes.

[0025] The sensor module further includes a hazardous substance detection sensor unit for detecting the concentration of various hazardous substances generated during the cooking process. The control unit compares the concentrations of various hazardous substances detected by the hazardous substance detection sensor unit with the reference values ​​of various hazardous substances pre-stored in the system, and adjusts the speed of the fan motor according to the comparison result.

[0026] Beneficial effects As described above, the present invention has the following effects.

[0027] First, it can selectively open or close movable air intake and exhaust pipes or indoor polluted air intake and exhaust pipes, thereby quickly and conveniently expelling cooking fumes and indoor polluted air. Furthermore, by continuously inhaling cooking fumes containing various harmful substances at a level above the baseline, occupational diseases such as lung cancer that may be caused can be prevented in advance. At the same time, it can significantly improve indoor air quality and automatically create a comfortable indoor air environment.

[0028] Secondly, by lowering the movable intake and exhaust pipes to the location where cooking fumes are generated, it can not only quickly draw in and expel cooking fumes, but also collect the cooking fumes from the side of the oil collection tray in a 360° direction into the fumes inlet, and then quickly discharge them through the movable intake and exhaust pipes and the fixed intake and exhaust pipes in sequence, thereby effectively protecting the health of the operator.

[0029] Third, the fumes produced during cooking are filtered out by an oil filter after entering the fume inlet, and then discharged outdoors through the outer casing of the pipe and the fixed intake and exhaust pipes. The fumes that fail to enter the fume inlet are drawn into the fume intake unit, filtered out by an oil filter, and then discharged outdoors through the movable pipe casing and the fixed intake and exhaust pipes. This allows for the rapid removal of most of the fumes, thereby solving the social problem of lung cancer caused by inhaling cooking fumes.

[0030] Fourth, the control unit uses the extracted data and calculated emission efficiency as learning data to control the operation of the emission mode switching device based on artificial intelligence, thereby automatically expelling cooking fumes or indoor polluted air.

[0031] Fifth, the control unit adjusts the position of the movable intake and exhaust pipe housing by automatically moving it up and down, and then drives the exhaust fan motor to automatically and quickly expel cooking fumes.

[0032] Sixth, the control unit compares the concentrations of various hazardous substances detected by the hazardous substance detection sensors with the baseline values ​​of various hazardous substances stored in its internal memory, and controls the speed (output) of the exhaust fan motor based on the comparison results.

[0033] The effects of the present invention are not limited to those described above, and other effects not mentioned above can be clearly understood by those skilled in the art from the description in the claims. Attached Figure Description

Figure 17 This is a schematic diagram illustrating cooking fumes entering the fume inlet from the side of the oil receiving platform in a 360° direction.

[0064] As shown in the figure, an artificial intelligence range hood 100 according to an embodiment of the present invention includes: a range hood body 110 disposed above a stove 10, which serves as a heating device; a fixed intake and exhaust duct 130 for guiding the intake and exhaust of cooking fumes and indoor polluted air; an exhaust fan module 140 for forcibly exhausting cooking fumes and indoor polluted air to the outside; a movable intake and exhaust duct 150 for drawing in and exhausting cooking fumes generated by the stove 10 during cooking, during vertical movement; a height adjustment module 160 for adjusting the vertical position of the movable intake and exhaust duct 150; an indoor polluted air intake and exhaust duct 170 for guiding the intake and exhaust of indoor polluted air; and an exhaust mode switching device 180 for selectively opening or closing the fixed intake and exhaust duct 130 or the indoor polluted air intake and exhaust duct 170 to adjust the exhaust mode.

[0065] The components of an artificial intelligence range hood 100 according to an embodiment of the present invention are as follows.

[0066] First, such as Figure 15 and Figure 16 As shown, the range hood body 110 is installed at an appropriate height above the stove 10, which serves as a heating device. The heating device here includes not only gas stoves but also induction cookers, etc.

[0067] like Figures 1 to 6 As shown, the range hood body 110 can be composed of a bottom base plate 110A and an outer shell 110B.

[0068] An oil fume intake 111 is formed at the lower part of the bottom substrate 110A (see...). Figure 2 The fume inlet 111 refers to an opening capable of drawing in fumes.

[0069] A frame portion F is attached to the outer periphery of the bottom substrate 110A to protect the appearance, and a removable and replaceable filter screen 113 is installed inside the frame portion F.

[0070] A pipe guide hole 112 is formed in the center of the filter screen 113. The movable intake and exhaust pipe 150 is inserted into the pipe guide hole 112. When it moves up and down, it guides the movable intake and exhaust pipe 150 to move up and down.

[0071] The filter screen 113 serves to filter out impurities such as grease contained in the fumes produced during cooking.

[0072] The range hood base plate 110A is not limited to a rectangular structure and can be made into various shapes according to design conditions.

[0073] The outer casing 110B is vertically mounted above the base plate 110A of the range hood, and an intake port 117 for drawing in indoor polluted air is provided on the side of the casing 110B.

[0074] In addition, the fixed intake and exhaust duct 130 is vertically fixed inside the outer casing 110B to guide the intake and exhaust of polluting gases (such as cooking fumes and indoor polluted air).

[0075] The fixed intake and exhaust pipe 130 is preferably composed of a smooth rigid PVC pipe, a flexible PVC pipe, or a stainless steel pipe to prevent grease and other substances from adhering to its inner wall.

[0076] At the same time, such as Figure 13 and Figure 14 As shown, the exhaust fan module 140 is installed on the upper part of the outer casing 110B and is used to force the polluted gas guided by the fixed intake and exhaust pipes 130 to be discharged outdoors.

[0077] The exhaust fan module 140 includes a fan or blower, also known as an exhaust fan.

[0078] In addition, the movable intake and exhaust pipe 150 is movably installed at the lower part of the fixed intake and exhaust pipe 130, so that it moves up and down along the guide hole 112 to draw in and exhaust the cooking fumes generated when the stove 10 is cooking food.

[0079] like Figure 5 and Figure 6 As shown, the movable intake and exhaust duct 150 may include a movable duct housing 151 for guiding oil fumes; an oil filter 152 installed on the replaceable movable duct housing 151 for filtering components such as grease in the fumes during the intake and exhaust of cooking fumes when food is cooked on the stove 10; and an oil collection tray 153 that is closable and installed on the lower side of the movable duct housing 151, has a plurality of cooking fume intake ports 153a formed on its outer peripheral surface, and has a closed structure at the lower end.

[0080] The movable intake and exhaust pipe 150 is entirely replaceable and can be configured so that only the oil filter 152 needs to be replaced.

[0081] The oil collection tray 153 is configured to protrude from below the base plate 110A of the range hood, thereby enabling the intake and exhaust of cooking fumes at any time through the cooking fume inlet 153a (see...). Figure 9 ).

[0082] The oil collection tray 153 serves to temporarily collect grease and other substances that drip down after being filtered by the oil filter screen 152, in order to prevent the filtered grease and other substances from falling onto the food container.

[0083] The oil collecting tray 153 has a cap-like structure with a closed bottom to prevent falling grease and other substances from overflowing. Furthermore, to allow cooking fumes to be drawn in from a 360° direction, a cooking fume inlet 153a is formed radially on the outer peripheral surface of the oil collecting tray 153 (see...). Figure 16 and Figure 17 ).

[0084] In addition, an oil collection tray 153 can be detachably installed on the lower part of the pipe housing 151.

[0085] By removing the oil collection tray 153 from the lower part of the pipe housing 151, the collected grease and other substances can be removed, and then the oil collection tray 153 can be reinstalled on the lower part of the pipe housing 151.

[0086] The liquid grease filtered by the oil filter 152 is configured to flow into and collect on the inner bottom surface of the oil collection tray 153, so that the grease will not be exposed, thus maintaining the aesthetic appearance of the overall appearance.

[0087] The detachable structure of the oil collecting plate 153 is not limited to this embodiment and can be modified into various forms as needed. For example, although not shown in the drawings, a connecting groove can be formed below the pipe housing 151, and a connecting protrusion can be formed above the oil collecting plate 153, with the connecting protrusion inserted into the connecting groove for fixation.

[0088] In addition, the height adjustment module 160 is used to adjust the vertical height of the movable intake and exhaust pipe 150.

[0089] like Figure 7 , Figure 9 and Figure 10 As shown, the height adjustment module 160 includes: a winding motor 161 that generates power; a winding roller 162 mounted on the rotating shaft 161a of the winding motor 161; and a winding steel wire 163 with one end fixed to a movable air intake and exhaust pipe 150 and capable of being wound around the winding roller 162.

[0090] By utilizing the power of the winding motor 161, the winding roller 162 is rotated in the forward or reverse direction, thereby winding and unwinding the steel wire 163, so as to adjust the vertical position of the movable intake and exhaust pipe 150.

[0091] Furthermore, the indoor polluted air intake and exhaust duct 170 is connected to the middle of the fixed intake and exhaust duct 130, used to guide the intake and exhaust of indoor polluted air, and can be fixedly installed on the outer casing 110B (see...). Figure 13 ).

[0092] Additionally, refer to Figure 8 , Figure 11 and Figure 12 The exhaust mode switching device 180 is used to selectively open or close the movable intake and exhaust pipe 150 or the indoor polluted air intake and exhaust pipe 170 to exhaust cooking fumes or indoor polluted air generated when the stove 10 is cooking food.

[0093] The exhaust mode switching device 180 includes: a baffle 181 that can rotate around a hinge axis 181a at the middle of a fixed intake and exhaust duct 130 to selectively open or close the indoor polluted air intake and exhaust duct 170 or the movable intake and exhaust duct 150; a baffle rotation motor 182 that drives the baffle 181 to rotate around the hinge axis 181a; and a linkage bracket 183 that connects the baffle 181 and the baffle rotation motor 182 via the motor hinge axis 182a.

[0094] In the exhaust mode switching device 180, by driving the baffle rotation motor 182, the baffle 181 is rotated around the motor hinge shaft 182a, thereby selectively opening or closing the indoor polluted air intake and exhaust pipe 170 or the movable intake and exhaust pipe 150.

[0095] The outer periphery of the baffle 181 extends in a stepped manner to form a hinge shaft 181a. This hinge shaft 181a is tightly fitted and supported by a step 130a formed on the inner side of the fixed intake and exhaust pipe 130. This allows the baffle 181 to stably and selectively open or close the indoor polluted air intake and exhaust pipe 170 or the movable intake and exhaust pipe 150. As a result, cooking fumes or indoor polluted air generated when the stove 10 is cooking can be quickly discharged. When the exhaust fan motor 140 forces the cooking fumes or indoor polluted air to be discharged outdoors, the discharge efficiency can be maximized (see...). Figure 11 and Figure 12 ).

[0096] The step 130a refers to the part formed on the inlet side of the indoor polluted air intake and exhaust duct 170 or the movable intake and exhaust duct 150, used to support the hinge shaft 181a.

[0097] The operation and effects of the artificial intelligence range hood 100 of this invention, configured as described in this embodiment, are as follows.

[0098] In an artificial intelligence range hood 100 according to an embodiment of the present invention, the user can alternately open or close the movable intake and exhaust pipe 150 or the indoor polluted air intake and exhaust pipe 170 through the exhaust mode switching device 180, so that the cooking fumes or indoor polluted air generated during the cooking process of the stove 10 can be quickly and efficiently discharged.

[0099] Although not shown in the accompanying drawings, the operation of the present invention can be controlled by the user manually or automatically, and multiple operation buttons can be provided on the front of the range hood base plate 110A or on a separate operation panel.

[0100] In the description of this invention, for ease of understanding of the exhaust process of cooking fumes and indoor polluted air, it will be represented as follows: cooking fumes generated by the stove 10 when cooking food are represented by arrow ①; cooking fumes entering through the cooking fumes inlet 153a are represented by arrow ②; cooking fumes entering through the filter screen 113 are represented by arrow ③; indoor polluted air entering the indoor polluted air intake and exhaust duct 170 is represented by arrow ④; and polluted gas discharged to the outside is represented by arrow ⑤.

[0101] The process of inhaling and exhaling cooking fumes is described below.

[0102] When food is cooked on the stove 10 and cooking fumes are produced, such as Figure 14 and Figure 15 As shown, through the exhaust mode switching device 180, the indoor polluted air intake and exhaust duct 170 is closed, while the movable intake and exhaust duct 150 is opened.

[0103] Reference Figure 11 and Figure 12 The working principle of the exhaust mode conversion device 180 is as follows: after the baffle rotation motor 182 is started, it drives the baffle 181 to rotate around the hinge shaft 181a, thereby closing the indoor polluted air intake and exhaust pipe 170 and opening the movable intake and exhaust pipe 150.

[0104] Next, as Figure 16 As shown, the height of the movable intake and exhaust pipe 150 is adjusted by the height adjustment module 160, that is, the movable intake and exhaust pipe 150 is lowered.

[0105] From the operation of the height adjustment module 160, when the winding motor 161 starts and releases the winding wire 163, the movable pipe housing 151 and the oil collection tray 153 descend simultaneously. At this time, the descent positions of the movable pipe housing 151 and the oil collection tray 153 can be appropriately adjusted according to the amount of cooking fumes generated (see...). Figure 10 and Figure 16 ).

[0106] When the exhaust fan motor 140 operates and generates suction, cooking fumes are drawn in from a 360° direction through the cooking fume inlet 153a (see [link]). Figure 17 Subsequently, the cooking fumes pass through the oil filter 152, where the grease (oil vapor) is filtered out, and then pass through the movable pipe housing 151 and the fixed intake and exhaust pipe 130 in sequence, and are finally discharged to the outside (atmosphere).

[0107] like Figure 16 and Figure 17 As shown, cooking fumes (arrow ①) are rapidly drawn in from a 360° direction through the cooking fume inlet 153a (arrow ②). Therefore, the efficiency of inhalation and exhaust can be significantly improved not only in confined spaces but also in wider areas, and it has the effect of preventing lung cancer caused by inhaling cooking fumes.

[0108] In addition, some cooking fumes that fail to be drawn in through the cooking fume inlet 153a (arrow ③) will enter the interior of the cooking fume inlet 111, and after being filtered by the oil filter 152 to remove grease, will pass through the movable pipe housing 151 and the fixed intake and exhaust pipe 130 in sequence, and finally be discharged to the outside (atmosphere) (arrow ⑤).

[0109] The following describes the process of removing polluted indoor air.

[0110] When there is cooking fumes or indoor polluted air (arrow ④) that cannot be drawn in and discharged through the movable intake and exhaust duct 150 and need to be discharged, the movable intake and exhaust duct 150 is closed by the exhaust mode switching device 180, and the indoor polluted air intake and exhaust duct 170 is opened at the same time.

[0111] Reference Figures 11 to 13 Observe the working process of the exhaust mode conversion device 180. When the baffle rotation motor 182 is started, the baffle 181 rotates around the hinge shaft 181a, thereby closing the movable intake and exhaust pipe 150 and opening the indoor polluted air intake and exhaust pipe 170.

[0112] As the exhaust fan motor 140 generates suction, indoor polluted air is drawn in through the indoor polluted air intake and exhaust duct 170 and the fixed intake and exhaust duct 130 and finally discharged to the outside atmosphere (arrow ⑤).

[0114] In this figure, the same components as the artificial intelligence range hood 100 in one embodiment of the present invention are given the same reference numerals, and their detailed descriptions are omitted here.

[0115] Further reference Figure 18 Another embodiment of the artificial intelligence range hood of the present invention includes a structure that uses a sensing module to detect cooking fumes and indoor polluted air and automatically performs the exhaust function.

[0116] According to another embodiment of the present invention, an artificial intelligence range hood includes: a sensing module S consisting of a first sensing unit S1 for detecting cooking fumes and a second sensing unit S2 for detecting indoor polluted air; and a control unit C for receiving detection signals from the first sensing unit S1 and the second sensing unit S2, thereby controlling the operation of an exhaust fan motor 140 and an exhaust mode switching device 180 to selectively exhaust cooking fumes or indoor polluted air.

[0117] The first sensor S1 is installed on the base plate 110A of the range hood and is used to detect the cooking fumes generated during the cooking process and transmit the detection value to the control unit C.

[0118] Based on the detection value, the control unit C uses the extracted data and the calculated cooking fume exhaust efficiency as learning data for artificial intelligence calculations, thereby automatically adjusting the exhaust mode switching device 180 to achieve rapid intake and exhaust of cooking fumes.

[0121] Meanwhile, the sensing module S may further include a hazardous substance detection sensor S4 for detecting the concentration of various hazardous substances generated during the cooking process.

[0122] The control unit C compares the concentrations of various harmful substances detected by the harmful substance detection sensor S4 with the reference values ​​of various harmful substances stored in its internal memory, and adjusts the speed of the exhaust fan motor 140 according to the comparison results, thereby realizing the rapid discharge of various harmful substances.

This allows for the rapid removal of most of the fumes, thereby solving the social problem of lung cancer caused by inhaling cooking fumes.

[0127] Fourth, the control unit uses the extracted data and calculated emission efficiency as learning data to control the operation of the emission mode switching device based on artificial intelligence, thereby automatically expelling cooking fumes or indoor polluted air.

[0128] Fifth, the control unit adjusts the position of the movable intake and exhaust pipe housing by automatically moving it up and down, and then drives the exhaust fan motor to automatically and quickly expel cooking fumes.
