Description

Technical Field

[0001] The present invention relates to an artificial intelligence range hood, and more specifically, by selectively opening or blocking a movable exhaust duct or an indoor polluted air exhaust duct, cooking fumes and indoor polluted air can be quickly and easily discharged. Moreover, not only that, but since the cooking fumes are quickly sucked from 360° directions through the cooking fume suction holes of the oil receiver, the suction and discharge efficiency can be improved not only in a narrow place but also in a wide place, and the occurrence of lung cancer caused by the inhalation of cooking fumes can be effectively prevented. It relates to an artificial intelligence range hood.

Background Art

[0002] Generally, a hood system is a device provided to timely discharge air pollution sources such as heat generation, odors, smoke, soot, waste gas, and steam generated during the cooking of various foods, and to prevent indoor air pollution. With the recognition of consumers who attach importance to health, its penetration rate has increased rapidly.

[0003] A conventional hood system is provided separately above a range, which is a heating device, so that cooking gases generated during food cooking can be sucked.

[0004] A range is a device for cooking food using gas or electricity. A gas range or an electric range is a device for cooking food using gas or electricity.

[0005] An IH cooking heater type range applies an indirect method of inducing heat to the heated body (pan) itself using a magnetic field. Such an IH cooking heater can reduce indoor air pollution compared to a gas range, and since the heat generation from the device itself is small, it can suppress the rise in indoor temperature in summer. Since the top plate is not heated, there is no damage such as burns caused by heat, and the biggest advantage is quick cooking, so it has been widely used in recent years.

[0006] In general, cooking spaces, including large kitchens in restaurants, schools, and businesses that prepare meat, fish, Chinese food, and fried foods, generate large amounts of steam and cooking oil fume (various harmful substances including harmful gases and fine particles generated when cooking food by frying or grilling), leading to indoor air pollution. Examples of such steam and cooking fumes include fats and fatty acids generated when grilling or frying meat and fish, odorous substances with amine groups that are the main component of fishy odor, ethyl alcohol used as a meat tenderizer, aromatic hydrocarbons containing volatile substances that are the main components of the aroma and odor of various spices and seasonings, carcinogens such as benzopyrene and formaldehyde and nitrogen oxides (NOx) generated during heating and carbonization, and mixed gases formed when carbon monoxide (CO) is burned, resulting in carbon dioxide (CO2), fly ash, and ultrafine dust mixed with air and water vapor.

[0007] Indoor air pollution caused by cooking fumes generated in kitchens not only induces foul odors but also has adverse effects on human health, so it must be removed. Therefore, the International Agency for Research on Cancer (IARC) classifies such cooking fumes as carcinogenic substances, and for this reason, the government recognizes lung cancer among cooks and other workers exposed to cooking fumes as a work-related injury.

[0008] Conventional hood systems include an intake section capable of drawing in cooking gases, and a hood body connected to the upper part of the intake section, which allows the cooking gas drawn in through the intake section to pass upwards.

[0009] The aforementioned air intake is equipped with a filter or lighting, and a blower is provided on one side of the air intake or hood body to ensure smooth intake and discharge of cooking fumes.

[0010] However, conventional hood systems are designed so that cooking fumes are sucked in and discharged only from the upper part of the hood range. This results in a large distance between the point where cooking fumes are generated and the point where they are sucked in and discharged, which poses a health risk to users who inhale cooking fumes.

[0011] Furthermore, in conventional hood systems, the majority of the suction duct is formed with a structure that has circular holes and is open at the bottom. Cooking fumes are sucked in and discharged through this open section, which is efficient in suction and discharge in confined spaces, but the efficiency is significantly reduced in open spaces, and there is a problem that lung cancer can be caused by inhaling cooking fumes. [Overview of the Initiative] [Problems that the invention aims to solve]

[0012] The present invention was made to improve the aforementioned problems, and the first problem that the present invention aims to solve is to provide an artificial intelligence range hood that can quickly and easily discharge cooking fumes and indoor polluted air by selectively opening or closing a movable intake / exhaust duct or an indoor polluted air intake / exhaust duct, prevent occupational accidents such as lung cancer that may occur by continuously sucking in cooking fumes containing various harmful substances in amounts exceeding a standard, significantly improve indoor air quality, and automatically create a comfortable indoor air quality environment.

[0013] The second problem that the present invention aims to solve is to provide an artificial intelligence range hood that not only enables rapid suction and discharge of cooking fumes by lowering the movable intake and exhaust duct to the area where cooking fumes are generated, but also protects the health of cooks by being configured so that cooking fumes are collected in the cooking fume suction holes from a 360° direction on the side of the oil receiving tray, and then rapidly discharged sequentially through the movable intake and exhaust duct and the fixed intake and exhaust duct.

[0014] The third problem that the present invention aims to solve is to provide an artificial intelligence range hood that can control the operation of the exhaust mode switching means based on artificial intelligence, automatically exhaust cooking fumes or indoor polluted air, automatically adjust the position of the duct housing of the movable intake and exhaust duct by moving it up and down, then drive the hood fan motor to automatically and quickly exhaust cooking fumes, and also compare the concentration of various harmful substances detected by the harmful substance detection sensor with the reference values ​​for various harmful substances stored inside it, and control the rotation speed (output) of the hood fan motor according to the resulting value.

[0015] The technical problems of the present invention are not limited to those described above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0017] Furthermore, the movable intake and exhaust duct may be configured to include a movable duct housing for guiding cooking fumes, an oil filter that is interchangeably provided in the movable duct housing and filters out oil and other substances contained in cooking fumes when sucking up cooking fumes generated during food cooking in the range, and an oil receiving stand that is openable and closable at the bottom of the movable duct housing and has numerous cooking fume suction holes formed on its outer surface.

[0018] Furthermore, the lifting adjustment module includes a winding motor that generates power, a winding roll provided on the rotating shaft of the winding motor, and a winding wire whose end is fixed to the movable intake and exhaust duct and which can be wound onto the winding roll. The vertical position (lifting and lowering) of the movable intake and exhaust duct can be adjusted by using the power of the winding motor to rotate the winding roll in the forward or reverse direction and winding or unwinding the winding wire.

[0019] Furthermore, the exhaust mode switching means may include a damper rotatably mounted in the middle of the fixed intake / exhaust duct around a hinge axis to selectively open or close the indoor contaminated air intake / exhaust duct or the movable intake / exhaust duct, a damper rotation motor for rotating the damper around the hinge axis, and an arm bracket connecting the damper and the hinge axis.

[0020] Furthermore, of the cooking fumes generated during food preparation, those that flow into the cooking fume suction port are filtered for oil (oil vapor) via an oil filter, and then discharged to the outside (atmosphere) through the duct housing and the fixed intake and exhaust duct.

[0021] Furthermore, during food preparation, cooking fumes that move upward but do not flow into the cooking fume suction port are configured to flow into the filter mesh of the cooking fume suction unit, filter out oil through the oil filter, and then be discharged to the outside (atmosphere) through the movable duct housing and the fixed intake and exhaust duct.

[0022] Furthermore, 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 that receives signal values ​​detected by the first sensor unit and the second sensor unit and controls the operation of the hood fan motor and the discharge mode switching means so that cooking fumes or indoor polluted air can be selectively discharged.

[0023] The control unit can use the extracted data and the calculated emission efficiency as learning data and control the operation of the emission mode switching means based on artificial intelligence.

[0024] In addition, the sensor module further includes a third sensor unit that detects the height of the food cooking container. The control unit receives the signal value detected by the third sensor unit, adjusts the position while automatically moving the duct housing of the movable intake and exhaust duct up and down, and then drives the hood fan motor to suck and discharge cooking fumes.

[0028] Second, by lowering the movable intake and exhaust duct to the part where cooking fumes are generated, not only can the cooking fumes be quickly sucked and discharged, but also after the cooking fumes are collected from the 360° direction of the side of the oil receiver into the cooking fume suction holes, they are configured to be discharged sequentially through the movable intake and exhaust duct and the fixed intake and exhaust duct, thus protecting the health of the cook.

[0029] Third, among the cooking fumes generated during food cooking, the cooking fumes flowing into the cooking fume suction holes are filtered for oil content (oil vapor) through an 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 food cooking, the cooking fumes that do not flow into the cooking fume suction holes flow into the cooking fume suction part, and after the oil content is filtered through an oil filter, they are discharged to the outside through the movable duct housing and the fixed intake and exhaust duct, thereby quickly discharging almost all of the cooking fumes and solving the social problem of lung cancer caused by the inhalation of cooking fumes.

[0030] Fourth, the control unit utilizes the extracted data and the calculated discharge efficiency as learning data, controls the operation of the discharge mode switching means based on artificial intelligence, and can automatically discharge cooking fumes or indoor polluted air.

[0046] As shown in the figure above, an artificial intelligence range hood 100 according to one embodiment of the present invention has the following technical features: a hood body 110 located above a range 10 which is a heating mechanism; a fixed intake and exhaust duct 130 for guiding the intake and discharge of cooking fumes and indoor contaminated air; a hood fan motor 140 for forcibly discharging cooking fumes and indoor contaminated air to the outside; a movable intake and exhaust duct 150 that moves up and down to suck in and discharge fumes generated when cooking food in the range 10; a lifting and lowering adjustment module 160 for adjusting the vertical position of the movable intake and exhaust duct 150; an indoor contaminated air intake and exhaust duct 170 for guiding the intake and discharge of indoor contaminated air; and an exhaust mode switching means 180 that can selectively open or close the fixed intake and exhaust duct 130 or the indoor contaminated air intake and exhaust duct 170 to adjust the exhaust mode.

[0047] The components of the artificial intelligence range hood 100 according to one embodiment of the present invention are as follows:

[0048] First, the hood body 110 is positioned above the heating mechanism, the range 10, with a fixed range of motion (see Figures 15 and 16). Here, the heating mechanism includes not only gas ranges but also induction cooktops and the like.

[0049] As shown in Figures 1 to 6, the hood body 110 may consist of a hood base plate 110A and an outer casing 110B.

[0050] A cooking fume suction section 111 (shown in Figure 2) is formed at the lower part of the hood base plate 110A. The cooking fume suction section 111 refers to an opening that can suck up cooking fumes.

[0051] A frame portion (F) is attached to the outer casing of the hood base plate 110A to protect its appearance, and the filter mesh 113 is configured to be replaceable by attaching and detaching it within the frame portion (F).

[0052] A duct guide hole 112 is formed in the center of the filter mesh 113. The movable intake and exhaust duct 150 is inserted into the duct guide hole 112, and when it moves up and down, the duct guide hole 112 serves to guide the vertical movement of the movable intake and exhaust duct 150.

[0053] The aforementioned filter mesh 113 serves to filter out oil and other substances contained in cooking fumes generated during cooking.

[0054] The hood base plate 110A is not limited to a rectangular shape and may be formed into various shapes depending on the design conditions.

[0055] The outer casing 110B is mounted vertically on the upper part of the base plate 110A. A suction port 117 for drawing in indoor contaminated air is formed on the side of the outer casing 110B.

[0056] Furthermore, the fixed intake and exhaust duct 130 is vertically fixed inside the outer casing 110B to guide the intake and discharge of contaminated gases (including, for example, cooking fumes and indoor contaminated air).

[0057] The fixed intake and exhaust duct 130 is preferably composed of a smooth, rigid PVC pipe, a flexible PVC duct hose, and a stainless steel duct, so as not to allow oil or other substances to accumulate on its inner surface.

[0058] Furthermore, the hood fan motor 140 (shown in Figures 13 and 14) is installed on the upper side of the outer casing 110B to forcibly discharge the contaminated gas guided by the fixed intake and exhaust duct 130 to the outside.

[0059] The aforementioned hood fan motor 140 includes a fan or blower, which is called an exhaust fan.

[0060] Furthermore, the movable intake and exhaust duct 150 is provided below the fixed intake and exhaust duct 130 so as to move up and down along the duct guide hole 112, sucking in and discharging cooking fumes generated when cooking food in the range 10.

[0061] As shown in Figures 5 and 6, the movable intake and exhaust duct 150 can be configured to include a movable duct housing 151 for guiding cooking fumes, an oil filter 152 which is replaceably provided in the movable duct housing 151 and filters oil and other substances contained in cooking fumes when sucking up and discharging cooking fumes generated when cooking food in the range 10, and an oil receiving stand 153 which is openable and closable and provided at the bottom of the movable duct housing 151, and has a structure in which numerous cooking fume suction holes 153a are formed on its outer circumferential surface and the lower end is closed.

[0062] The entire movable intake and exhaust duct 150 is replaceable, and it can be configured so that only the oil filter 152 can be replaced.

[0063] The oil receiving stand 153 is configured to remain protruding below the hood base plate 110A, and cooking fumes can be continuously sucked in and discharged through the cooking fume suction hole 153a (see Figure 9).

[0064] The oil receiving tray 153 serves to temporarily collect the oil and other substances filtered by the oil filter 152 as they fall downward, preventing them from dripping onto the food container.

[0065] The oil receiving stand 153 is formed in a cap shape with its lower part closed to prevent dripping oil and other substances from falling, and cooking fume suction holes 153a are formed radially along the outer surface of the oil receiving stand 153 so that cooking fumes can be sucked up from 360° directions (see Figures 16 and 17).

[0066] Furthermore, an oil receiving tray 153 can be detachably provided at the lower part of the duct housing 151.

[0067] At the bottom of the duct housing 151, the oil receiving tray 153 can be separated, and after removing the oil and other substances collected in the oil receiving tray 153, the oil receiving tray 153 can be reattached to the lower part of the duct housing 151.

[0068] The liquid oil filtered through the oil filter 152 flows into the inner bottom surface of the oil receiving stand 153 and is collected there, so that the oil is not exposed to the outside, thus protecting the aesthetic appearance.

[0069] The attachment and detachment structure of the oil receiving stand 153 is not limited to this embodiment and can be changed to a variety of structures. For example, although not shown, a coupling groove can be formed in the lower part of the duct housing 151, and a coupling projection can be formed facing upward toward the oil receiving stand 153, and the coupling projection can be inserted into the coupling groove.

[0070] Furthermore, the height adjustment module 160 adjusts the height of the movable intake and exhaust duct 150.

[0071] As shown in Figures 7, 9, and 10, the lifting adjustment module 160 includes a winding motor 161 that generates power, a winding roll 162 provided on the rotating shaft 161a of the winding motor 161, and a winding wire 163 whose end is fixed to the movable intake and exhaust duct 150 and which is wound onto the winding roll 162.

[0072] The winding motor 161 is used to rotate the winding roll 162 in the forward or reverse direction, thereby winding or unwinding the winding wire 163 to adjust the vertical position (up and down) of the movable intake and exhaust duct 150.

[0073] Furthermore, the indoor contaminated air intake and exhaust duct 170 can be connected to the fixed intake and exhaust duct 130 in the middle to guide the intake and discharge of indoor contaminated air, and can be fixedly installed on its outer casing 110B (see Figure 13).

[0074] Furthermore, referring to Figures 8, 11, and 12, the discharge mode switching means 180 selectively opens or closes the movable intake / exhaust duct 150 or the indoor contaminated air intake / exhaust duct 170 to discharge cooking fumes or indoor contaminated air generated when cooking food in the range 10.

[0075] The exhaust mode switching means 180 includes a damper 181 rotatably mounted in the middle of the fixed intake / exhaust duct 130 around a hinge shaft 181a so as to selectively open and close the indoor contaminated air intake / exhaust duct 170 or the movable intake / exhaust duct 150, a damper rotation motor 182 for rotating the damper 181 around the hinge shaft 181a, and an arm bracket 183 connecting the damper 181 and the motor hinge shaft 182a of the damper rotation motor 182.

[0076] The discharge mode switching means 180 is configured to selectively open and close the indoor contaminated air intake and exhaust duct 170 or the movable intake and exhaust duct 150 by driving the damper rotation motor 182 to rotate the damper 181 around the motor hinge shaft 182a.

[0077] A stopper 181b is further extended in a stepped manner from the outer circumference of the damper 181. The stopper 181b is tightly supported by a step 130a formed inside the fixed intake / exhaust duct 130, so that the damper 181 can stably selectively open and close the indoor contaminated air intake / exhaust duct 170 or the movable intake / exhaust duct 150. This configuration allows for the rapid discharge of cooking fumes or indoor contaminated air generated when cooking food in the range 10, and maximizes the discharge efficiency when the hood fan motor 140 forcibly discharges cooking fumes or indoor contaminated air to the outside (see Figures 11 and 12).

[0078] The aforementioned step 130a is a portion formed on the inlet side of the indoor contaminated air intake / exhaust duct 170 or the movable intake / exhaust duct 150, and is intended to support the stopper 181b.

[0079] The operation and effects of the artificial intelligence range hood 100 according to one embodiment of the present invention configured in this manner are as follows.

[0080] In one embodiment of the present invention, the artificial intelligence range hood 100 allows the user to quickly and effectively discharge cooking fumes or indoor contaminated air generated during food cooking in the range 10 by alternately opening or closing the movable intake / exhaust duct 150 or the indoor contaminated air intake / exhaust duct 170 using the exhaust mode switching means 180.

[0081] Although not shown in the illustration, the operation of the present invention may be operated manually or automatically by the user by providing numerous operation buttons on the front of the hood base plate 110A or on a separate operation panel. In the description of the present invention, to facilitate understanding of cooking fumes and the discharge of indoor polluted air, cooking fumes generated when cooking food in range 10 are indicated by the arrows. Represented as TIFF2026529039000002.tif2016, the cooking fumes flowing in through the cooking fume suction hole 153a are indicated by the arrows. Represented as TIFF2026529039000003.tif1716, the cooking fumes flowing in through the filter mesh 113 are indicated by the arrows. Represented as TIFF2026529039000004.tif1616, the indoor polluted air flowing into the indoor polluted air intake / exhaust duct 170 is indicated by the arrow. Represented as TIFF2026529039000005.tif1716, polluting gases emitted to the outside are indicated by arrows. It is represented as TIFF2026529039000006.tif1816.

[0082] The following describes the process of suctioning and discharging cooking fumes.

[0083] When cooking food in the range 10, if cooking fumes are generated, the exhaust mode switching means 180 shuts off the indoor contaminated air intake and exhaust duct 170 while opening the movable intake and exhaust duct 150, as shown in Figures 14 and 15.

[0084] Regarding the operation of the discharge mode switching means 180 (see Figures 11 and 12), the damper rotation motor 182 is driven, and the damper 181 is rotated around the hinge shaft 181a, thereby blocking the indoor contaminated air intake and exhaust duct 170 while opening the movable intake and exhaust duct 150.

[0085] Next, as shown in Figure 16, the height adjustment module 160 is used to adjust the height of the movable intake and exhaust duct 150. That is, the movable intake and exhaust duct 150 is lowered.

[0086] Regarding the operation of the lifting adjustment module 160, the winding motor 161 drives the winding wire 163 to unwind and lower it, causing the movable duct housing 151 and the oil receiving stand 153 to also lower. At this time, the lowered position of the movable duct housing 151 and the oil receiving stand 153 is adjusted appropriately according to the amount of cooking fumes (see Figures 10 and 16).

[0087] The hood fan motor 140 generates a suction force, causing cooking fumes to be drawn in from 360° directions through the cooking fume suction port 153a (see Figure 17). The cooking fumes are then filtered to remove oil (oil vapor) via the oil filter 152, and then discharged to the outside (atmosphere) through the movable duct housing 151 and the fixed intake / exhaust duct 130.

[0088] As shown in Figures 16 and 17, cooking fumes (arrows) (TIFF2026529039000007.tif2016) is rapidly sucked in from 360° directions through the cooking fume suction hole 153a (arrow) (TIFF2026529039000008.tif1716), in confined spaces, and naturally in larger spaces as well, it can improve suction and discharge efficiency, and has the effect of preventing the induction of lung cancer caused by inhaling cooking fumes.

[0089] And, of the cooking fumes, the cooking fumes that did not flow into the cooking fume suction hole 153a (arrow) The fumes (TIFF2026529039000009.tif1616) flow into the cooking fume suction section 111, are filtered through the oil filter 152, and then discharged to the outside (atmosphere) through the movable duct housing 151 and the fixed intake / exhaust duct 130 (arrow). TIFF2026529039000010.tif1816).

[0090] The process for removing indoor polluted air is as follows:
