Description

Artificial intelligence range hood

[0001] The present invention relates to an artificial intelligence range hood, and more specifically, to an artificial intelligence range hood that can quickly and easily discharge cooking fumes and indoor polluted air by selectively opening or blocking a movable intake / exhaust duct or an indoor polluted air intake / exhaust duct, and can quickly suck in cooking fumes in a 360° direction through a cooking fume suction hole of an oil receiver, thereby increasing suction / exhaust efficiency in both narrow and wide spaces, and effectively preventing the induction of lung cancer caused by inhalation of cooking fumes.

[0002] In general, a hood system is a device installed to prevent indoor air pollution in advance by timely discharging air pollutants such as heat, cooking odor, smoke, soot, waste gas, and steam generated during cooking of various foods. Its distribution rate is rapidly increasing day by day due to the awareness of consumers who prioritize health.

[0003] Conventional hood systems are installed above the range, which is a heating device, to allow the cooking gases generated during food cooking to be sucked in.

[0004] A range is a device that cooks food using gas or electricity, and a gas range or microwave oven is a device that cooks food using gas or electricity.

[0005] Induction ranges use an indirect method of inducing heat to the heated object (pot) itself using a magnetic field. Compared to gas ranges, induction can reduce indoor air pollution, and because the device itself does not generate much heat, it can prevent the indoor temperature from rising in the hot summer, and because the top does not heat up, there is no damage such as burns due to heat, and its biggest advantage is quick cooking, so it is being widely used recently.

[0006] In general, cooking spaces such as restaurants, schools, and businesses that cook grilled meat, fish, Chinese food, and fried food, including large kitchens, generate large amounts of steam and cooking fumes (including various harmful substances such as harmful gases and particulate matter generated when frying or grilling food) during the cooking process, which has become a problem in indoor air pollution. These steams and cooking fumes include fat and fatty acids generated when grilling or frying meat or fish, amine-containing odorous substances that are the main components of a fishy smell, ethyl alcohol used as a meat tenderizer, the fragrance of various spices and cooking ingredients, aromatic hydrocarbons that contain volatile substances that are the main components of odor, carcinogens such as benzopyrene and formaldehyde generated when heated and carbonized, nitrogen oxides (NOx), carbon dioxide (CO2) generated from the combustion of carbon monoxide (CO), fly ash, and ultrafine dust, which are mixed gases with air and water vapor.

[0007] Indoor air pollution caused by cooking fumes generated within kitchens not only causes unpleasant odors but also has adverse effects on the human body, making them essential for their removal. Therefore, the International Agency for Research on Cancer (IARC) classifies cooking fumes as carcinogenic, and the government recognizes lung cancer among cooks working in environments exposed to cooking fumes as an industrial accident.

[0008] A conventional hood system is composed of an intake section capable of sucking in cooking gas, and a hood body that is connected to the upper part of the intake section and passes the cooking gas sucked in through the intake section upward.

[0009] The above intake section is equipped with a filter or light, and a blower is provided on one side of the intake section or hood body so that the cooking fumes are smoothly sucked in and discharged.

[0010] However, since the conventional hood system is structured to only suck and discharge cooking fumes from the upper part of the hood range, the distance between the point where cooking fumes are generated and the point where cooking fumes are sucked and discharged is large, and this causes the user to breathe in cooking fumes, which is harmful to their health.

[0011] In addition, in conventional hood systems, most of the suction ducts are formed in a circular hole structure with an open bottom, and the structure is configured to suck and discharge cooking fumes through the open part, so although the suction and discharge efficiency is high in narrow spaces, the suction and discharge efficiency is significantly low in wide spaces, and there is a problem of causing lung cancer due to inhalation of cooking fumes.

[0012] The present invention was invented to improve the above-mentioned problems, and the first problem to be solved by the present invention is to provide an artificial intelligence range hood that can quickly and easily discharge cooking fumes and indoor polluted air by selectively opening or blocking a movable intake / exhaust duct or an indoor polluted air intake / exhaust duct, can prevent industrial accidents such as lung cancer that may occur due to continuous inhalation of cooking fumes containing various harmful substances exceeding a standard amount, and can significantly improve indoor air quality and automatically create a pleasant indoor air quality environment.

[0013]

[0014] The second problem to be solved by the present invention is to provide an artificial intelligence range hood that can protect the health of the cook by not only quickly sucking and discharging cooking fumes by lowering the movable intake and exhaust duct to the area where cooking fumes are generated, but also quickly discharging cooking fumes by sequentially passing through the movable intake and exhaust ducts after being captured in the cooking fume suction holes from the 360° side of the oil pan.

[0015]

[0016] The third problem to be solved by the present invention is to provide an artificial intelligence range hood in which the control unit can automatically discharge cooking fumes or indoor polluted air by controlling the operation of the exhaust mode conversion means based on artificial intelligence, and the duct housing of the movable intake and exhaust duct can be automatically moved up and down to adjust its position and then the hood fan motor can be driven to automatically and quickly discharge cooking fumes, and the concentration of various hazardous substances detected by the hazardous substance detection sensor unit can be compared with the standard values ​​for various hazardous substances stored within the range hood, and the rotation speed (output) of the hood fan motor can be controlled in response to the resulting value.

[0017]

[0018] The technical problems of the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0019] In order to achieve the above object, an artificial intelligence range hood according to an example of the present invention comprises: a hood base plate having a plurality of cooking fume intake portions formed therein and a duct guide hole at the center thereof, and an outer casing vertically installed on the upper portion of the hood base plate, the hood body positioned above a heating device; a fixed intake / exhaust duct vertically fixedly installed on the inner upper portion of the outer casing to guide the intake and exhaust of cooking fumes and indoor polluted air generated during cooking; a hood fan motor installed on the upper portion of the fixed intake / exhaust duct to forcibly exhaust cooking fumes and indoor polluted air introduced into the fixed intake / exhaust duct to the outside; a fixed intake / exhaust duct installed on the upper portion of the fixed intake / exhaust duct to forcibly exhaust cooking fumes and indoor polluted air introduced into the fixed intake / exhaust duct to the outside; a movable intake / exhaust duct movably installed on the lower portion of the fixed intake / exhaust duct to suck and exhaust polluted gases generated during cooking in the range while moving up and down along the guide hole; The technical features include a height adjustment module for adjusting the position of the above-mentioned movable intake and exhaust duct up and down; an indoor polluted air intake and exhaust duct fixedly installed on the outer casing while connected to the middle of the above-mentioned fixed intake and exhaust duct to guide intake and exhaust of indoor polluted air; and an exhaust mode conversion means for selectively opening or blocking the above-mentioned movable intake and exhaust duct or the above-mentioned indoor polluted air intake and exhaust duct to exhaust polluted gas or indoor polluted air generated when cooking food in the above-mentioned range.

[0020]

[0021] In addition, the movable intake / exhaust duct may be configured to include a movable duct housing that guides cooking fumes; an oil filter that is replaceably installed in the movable duct housing and filters oil, etc. contained in the cooking fumes generated when cooking food in the range when the cooking fumes are inhaled; and an oil receiving plate that is openably installed on the lower side of the movable duct housing and has a plurality of cooking fume suction holes formed on the outer surface.

[0022]

[0023] In addition, the height adjustment module includes a winding motor that generates power; a winding roll installed on a rotational axis of the winding motor; and a winding wire whose end is fixed to the movable intake / exhaust duct and can be wound around the winding roll; wherein the winding roll is rotated in a forward or reverse direction using the power of the winding motor to wind or unwind the winding wire, thereby adjusting the up-and-down position (height) of the movable intake / exhaust duct.

[0024]

[0025] In addition, the exhaust mode conversion means may be configured to include a damper rotatably installed about a hinge axis in the middle of the fixed intake / exhaust duct to selectively open and close the indoor polluted air intake / exhaust duct or the movable intake / exhaust duct; a damper rotation motor that rotates the damper about the hinge axis; and an arm bracket that connects the damper and the hinge axis.

[0026]

[0027] In addition, among the cooking fumes generated during food cooking, the cooking fumes that enter the cooking fume suction hole are configured to pass through the oil filter to filter out oil (oil vapor) and then pass through the duct housing and the fixed intake / exhaust duct to be discharged to the outside (atmosphere).

[0028]

[0029] In addition, cooking fumes that move upward while cooking food but are not drawn into the cooking fume suction hole are drawn into the filter net of the cooking fume suction unit, and then pass through the oil filter to have the oil filtered, and then are discharged to the outside (atmosphere) through the movable duct housing and the fixed intake / exhaust duct.

[0030]

[0031] In addition, an artificial intelligence range hood according to another example of the present invention may further include a sensor module including a first sensor unit for detecting cooking fumes and a second sensor unit for detecting indoor polluted air; and a control unit for receiving signal values ​​detected by the first sensor unit and the second sensor unit and controlling the operation of the hood fan motor and the exhaust mode conversion means so as to selectively exhaust cooking fumes or indoor polluted air.

[0032] The above control unit can control the operation of the emission mode conversion means based on artificial intelligence by using the extracted data and calculated emission efficiency as learning data.

[0033]

[0034] In addition, the sensor module further includes a third sensor unit that detects the height of the food cooking container, and the control unit receives a signal value detected by the third sensor unit and automatically moves the duct housing of the movable intake / exhaust duct up and down to adjust its position, and then drives the hood fan motor to suck in and exhaust cooking fumes.

[0035]

[0036] In addition, the sensor module further includes a hazardous substance detection sensor unit that detects the concentration of various hazardous substances generated during cooking, and the control unit may be configured to compare the concentration of various hazardous substances detected by the hazardous substance detection sensor unit with the standard values ​​for various hazardous substances stored within the unit, and control the rotation speed of the hood fan motor in response to the result value.

[0037] As described above, the present invention has the following effects.

[0038] First, by selectively opening or blocking the movable intake / exhaust duct or indoor polluted air intake / exhaust duct, cooking fumes and indoor polluted air can be quickly and easily discharged, and industrial accidents such as lung cancer that can be caused by continuously inhaling cooking fumes containing various harmful substances exceeding the standard amount can be prevented in advance, and indoor air quality can be significantly improved, automatically creating a pleasant indoor air quality environment.

[0039] Second, by lowering the movable intake and exhaust duct to the area where cooking fumes are generated, not only can cooking fumes be quickly sucked in and discharged, but cooking fumes are captured in the 360° lateral direction of the oil pan into the cooking fume suction hole and then sequentially discharged through the movable intake and exhaust ducts, thereby protecting the health of the cook.

[0040] Third, among the cooking fumes generated during cooking, the cooking fumes that enter the cooking fume suction hole are filtered of oil (oil vapor) through the oil filter and then discharged to the outside through the duct housing and the fixed intake and exhaust duct. Among the cooking fumes generated during cooking, the cooking fumes that do not enter the cooking fume suction hole are drawn into the cooking fume suction unit and then pass through the oil filter to filter the oil and then discharged to the outside through the movable duct housing and the fixed intake and exhaust duct. As a result, most of the cooking fumes are quickly discharged, thereby solving the social problem of lung cancer caused by inhaling cooking fumes.

[0041] Fourth, the control unit can use the extracted data and calculated emission efficiency as learning data to control the operation of the emission mode conversion means based on artificial intelligence to automatically discharge cooking fumes or indoor polluted air.

[0042] Fifth, the control unit can automatically move the duct housing of the movable intake / exhaust duct up and down to adjust its position and then drive the hood fan motor to automatically and quickly exhaust cooking fumes.

[0043] Sixth, the control unit can compare the concentration of various hazardous substances detected by the hazardous substance detection sensor unit with the standard values ​​for various hazardous substances stored within the unit, and control the rotation speed (output) of the hood fan motor in response to the resulting value.

[0073] As illustrated in the drawing above, an artificial intelligence range hood (100) according to an embodiment of the present invention has technical features including: a hood body (110) positioned above a range (10), which is a heating device; a fixed intake / 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 / exhaust duct (150) for moving up and down to intake and exhaust cooking fumes generated when cooking food in the range (10); a height adjustment module (160) for adjusting the position of the movable intake / exhaust duct (150) up and down; an indoor polluted air intake / exhaust duct (170) for guiding the intake and exhaust of indoor polluted air; and an exhaust mode switching means (180) for selectively opening or blocking the fixed intake / exhaust duct (130) or the indoor polluted air intake / exhaust duct (170) to adjust the exhaust mode.

[0074]

[0075] The components of an artificial intelligence range hood (100) according to one embodiment of the present invention will be specifically examined as follows.

[0076] First, the hood body (110) is installed at a certain height above the range (10), which is a heating device (see FIGS. 15 and 16). Here, the heating device includes not only a gas range but also an induction range, etc.

[0077] As shown in FIGS. 1 to 6, the hood body (110) may be composed of a hood base plate (110A) and an outer casing (110B).

[0078] A cooking fume suction part (111) (shown in Fig. 2) is formed at the lower part of the above hood base plate (110A). The cooking fume suction part (111) refers to an opening through which cooking fume can be suctioned.

[0079] A frame part (F) is combined with the outer surface of the above hood base plate (110A) to protect the exterior, and a filter net (113) is configured to be detachably replaced inside the frame part (F).

[0080] A duct guide hole (112) is formed in the center of the above filter net (113). The movable intake / exhaust duct (150) is inserted into the duct guide hole (112), and when moving up and down, it serves to guide the up and down movement of the movable intake / exhaust duct (150).

[0081] The above filter net (113) serves to filter oil, etc. contained in cooking fumes generated during cooking.

[0082] The above hood base plate (110A) is not limited to a rectangular shape and can be formed into various shapes depending on design conditions.

[0083] The outer casing (110B) is installed vertically on the upper portion of the hood base plate (110A). An intake port (117) for sucking indoor polluted air is formed on the side of the outer casing (110B).

[0084]

[0085] In addition, the fixed intake / exhaust duct (130) is vertically fixedly installed inside the outer casing (110B) to guide the intake and exhaust of polluted gases (e.g., cooking fumes and indoor polluted air).

[0086] It is preferable that the above fixed intake / exhaust duct (130) be composed of a smooth rigid PVC pipe, a soft PVC duct hose, and a stainless steel duct to prevent oil, etc. from being deposited on the inner surface.

[0087]

[0088] In addition, the exhaust fan module (140) (shown in FIGS. 13 and 14) is installed on the upper side of the outer casing (110B) to forcibly discharge polluted gas guided by the fixed intake / exhaust duct (130) to the outside.

[0089] The above exhaust fan module (140) includes a fan or blower called an exhaust fan.

[0090]

[0091] In addition, the movable intake / exhaust duct (150) is installed so as to be able to move up and down at the bottom of the fixed intake / exhaust duct (130) so as to suck in and discharge cooking fumes generated when cooking food in the range (10) while moving up and down along the guide hole (112).

[0092] As illustrated in FIGS. 5 and 6, the movable intake / exhaust duct (150) may be configured to include a movable duct housing (151) that guides cooking fumes; an oil filter (152) that is replaceably installed in the movable duct housing (151) and filters oil, etc. contained in the cooking fumes when the cooking fumes are sucked and discharged during cooking in the range (10); and an oil receiver (153) that is openably installed on the lower side of the movable duct housing (151) and has a structure in which a plurality of cooking fume suction holes (153a) are formed on the outer surface and the lower end is closed.

[0093] The entire movable intake and exhaust duct (150) can be replaced, and only the oil filter (152) can be configured to be replaced.

[0094] The above oil receiving plate (153) is configured to remain in a state of protruding downward from the hood base plate (110A), so that cooking fumes can be sucked in and discharged at any time through the cooking fume suction hole (153a) (see FIG. 9).

[0095] The above oil receiving plate (153) temporarily collects oil, etc. filtered by the oil filter (152) when it falls downward, and prevents the filtered oil, etc. from falling upward of the food container.

[0096] The above oil receiving plate (153) is formed in a cap shape with a closed bottom to prevent fallen oil, etc. from overflowing, and furthermore, cooking fume suction holes (153a) are formed radially along the outer surface of the oil receiving plate (153) so that cooking fumes can be sucked in from a 360° direction (see FIGS. 16 and 17).

[0097] Additionally, an oil receiver (153) can be detachably installed at the bottom of the duct housing (151).

[0098] After removing the oil receiver (153) from the lower part of the duct housing (151) and removing oil, etc. collected in the oil receiver (153), the oil receiver (153) can be re-installed on the lower part of the duct housing (151).

[0099] The liquid oil filtered through the above oil filter (152) is configured to flow down to the inner bottom surface of the above oil receiving plate (153) and be captured, thereby protecting the appearance by preventing the oil from being exposed to the outside.

[0100] The detachable structure of the above oil receiver (153) is not limited to the present embodiment and may be changed into various structures. For example, although not shown in the drawing, a method may be used in which a coupling groove is formed at the bottom of the duct housing (151) and a coupling protrusion is formed at the top of the oil receiver (153), and the coupling protrusion is inserted into the coupling groove.

[0101]

[0102] In addition, the height adjustment module (160) adjusts the height of the movable intake and exhaust duct (150) up and down.

[0103] As shown in FIGS. 7, 9 and 10, the height adjustment module (160) comprises a winding motor (161) that generates power; a winding roll (162) installed on a rotational shaft (161a) of the winding motor (161); and a winding wire (163) whose end is fixed to a movable intake / exhaust duct (150) and can be wound around the winding roll (162).

[0104] It is configured to adjust the vertical position (height) of the movable intake / exhaust duct (150) by rotating the intake roll (162) in the forward or reverse direction using the power of the above-mentioned intake motor (161) to wind or unwind the intake wire (163).

[0105]

[0106] In addition, the indoor polluted air intake / exhaust duct (170) may be connected to the middle of the fixed intake / exhaust duct (130) to guide the intake / exhaust of indoor polluted air, and may be fixedly installed on the outer casing (110B) thereof (see FIG. 13).

[0107]

[0108] In addition, referring to FIGS. 8, 11 and 12, the exhaust mode conversion means (180) selectively opens or blocks the movable intake / exhaust duct (150) or the indoor polluted air intake / exhaust duct (170) to exhaust cooking fumes or indoor polluted air generated when cooking food in the range (10).

[0109] The above-mentioned exhaust mode conversion means (180) is configured to include a damper (181) that is rotatably installed about a hinge axis (181a) in the middle of a fixed intake / exhaust duct (130) to selectively open and close an indoor polluted air intake / exhaust duct (170) or the movable intake / exhaust duct (150); a damper rotation motor (182) that rotates the damper (181) about the hinge axis (181a); and an arm bracket (183) that connects the hinge axis (182a) of the damper (181) and the damper rotation motor (182).

[0110] In the above discharge mode conversion means (180), the damper rotation motor (182) is driven to rotate the damper (181) around the hinge axis (182a), thereby selectively opening and closing the indoor polluted air intake / exhaust duct (170) or the movable intake / exhaust duct (150).

[0111] A stopper (181a) is formed to extend further in steps on the outer periphery of the above damper (181), and the stopper (181a) is closely supported by a step (130a) formed on the inner side of the fixed intake / exhaust duct (130), so that the damper (181) can stably and selectively open and close the indoor polluted air intake / exhaust duct (170) or the movable intake / exhaust duct (150), and thus the cooking fumes or indoor polluted air generated when cooking food in the range (10) can be quickly discharged, so that when the hood fan motor (140) forcibly discharges the cooking fumes or indoor polluted air to the outside, the discharge efficiency can be maximized (see FIGS. 11 and 12).

[0112] The above step (130a) refers to a part formed on the inlet side of the indoor polluted air intake / exhaust duct (170) or the movable intake / exhaust duct (150) to support the stopper (181a).

[0113]

[0114] The operation and effect of the artificial intelligence range hood (100) according to one embodiment of the present invention configured as described above are as follows.

[0115] In an artificial intelligence range hood (100) according to one embodiment of the present invention, a user can quickly and effectively discharge cooking fumes or indoor polluted air generated when cooking food in a range (10) by alternately opening or blocking a movable intake / exhaust duct (150) or an indoor polluted air intake / exhaust duct (170) using an exhaust mode conversion means (180).

[0116] Although not shown in the drawing, the operation of the present invention may be performed manually or automatically by a user by providing multiple operation buttons on the front of the hood base plate (110A) or on a separate operation panel.

[0117]

[0118] In the description of the present invention, in order to help understand the emission of cooking fumes and indoor polluted air, the cooking fumes generated when cooking food in the range (10) are indicated by arrow ①, the cooking fumes introduced through the cooking fume intake hole (153a) are indicated by arrow ②, the cooking fumes introduced through the filter net (113) are indicated by arrow ③, the indoor polluted air introduced into the indoor polluted air intake / exhaust duct (170) is indicated by arrow ④, and the polluted gas discharged to the outside is indicated by arrow ⑤.

[0119]

[0120] Below, the cooking fume inhalation and emission process is explained as follows.

[0121] When cooking fumes are generated during cooking in the range (10), as shown in FIGS. 14 and 15, the indoor polluted air intake / exhaust duct (170) is blocked by the exhaust mode conversion means (180), while the movable intake / exhaust duct (150) is opened.

[0122] Looking at the operation of the exhaust mode conversion means (180) (see FIGS. 11 and 12), the damper rotation motor (182) is driven to rotate the damper (181) around the hinge axis (181a), thereby blocking the indoor polluted air intake / exhaust duct (170) while opening the movable intake / exhaust duct (150).

[0123] Next, as shown in Fig. 16, the height of the movable intake / exhaust duct (150) is adjusted by the height adjustment module (160). That is, the movable intake / exhaust duct (150) is lowered.

[0124] Looking at the operation of the above height adjustment module (160), the winding motor (161) is driven to release the winding wire (163) and lower it, thereby lowering the movable duct housing (151) and the oil receiving plate (153). At this time, the lowering positions of the movable duct housing (151) and the oil receiving plate (153) are appropriately adjusted according to the amount of cooking fumes (see FIGS. 10 and 16).

[0125] As suction power is generated by the operation of the hood fan motor (140), cooking fumes are sucked in from a 360° direction through the cooking fume suction hole (153a) (see Fig. 17). Thereafter, the cooking fumes pass through the oil filter (152) to filter the oil (oil vapor) contained in the cooking fumes, and are then discharged to the outside (atmosphere) through the movable duct housing (151) and the fixed intake / exhaust duct (130).

[0126] As shown in FIGS. 16 and 17, cooking fume (arrow ①) is quickly sucked in from a 360° direction through the cooking fume suction hole (153a) (arrow ②), so that the suction and discharge efficiency can be increased not only in narrow places but also in wide places, and there is an effect of preventing the induction of lung cancer due to inhalation of cooking fume.

[0127] And the cooking fume (arrow ③) that is not introduced into the cooking fume suction hole (153a) among the cooking fumes is introduced into the cooking fume suction part (111), passes through the oil filter (152), has the oil filtered, and then passes through the movable duct housing (151) and the fixed intake / exhaust duct (130) to be discharged to the outside (atmosphere) (arrow ⑤).

[0128]

[0129] Below, the indoor polluted air emission process is explained as follows.

[0130] In case there is a need to discharge cooking fumes or indoor polluted air (arrow ④) that remain indoors and cannot be discharged through the movable intake / exhaust duct (150), the movable intake / exhaust duct (150) is blocked by the discharge mode conversion means (180), while the indoor polluted air intake / exhaust duct (170) is opened.

[0131] Referring to FIGS. 11 to 13, the operation of the exhaust mode conversion means (180) is examined. As the damper rotation motor (182) is driven to rotate the damper (181) around the hinge axis (181a), the movable intake / exhaust duct (150) is blocked, while the indoor polluted air intake / exhaust duct (170) is opened.

[0132] As suction power is generated by the operation of the hood fan motor (140), indoor polluted air is discharged to the outside (atmosphere) through the indoor polluted air intake / exhaust duct (170) and the fixed intake / exhaust duct (130) (arrow ⑤).

[0133]

[0140] In addition, the sensor module (S) further includes a third sensor unit (S3) that detects the height of the food cooking container.

[0141] The above control unit (C) receives the signal value detected by the third sensor unit (S3), automatically moves the duct housing (151) of the movable intake / exhaust duct (150) up and down to adjust its position, and then drives the hood fan motor (140) to quickly inhale and discharge a large amount of cooking fumes.

[0142] In addition, the sensor module (S) further includes a hazardous substance detection sensor unit (S4) that detects the concentration of various hazardous substances generated during cooking.
