Description

Kitchen hood

The present disclosure relates to a kitchen hood.

Cooking often results in the release of harmful fumes, gases, oils or pollutants into the indoor air. Many kitchens have a kitchen hood installed above the stove to drain the remaining contaminants, and if not properly managed, the efficiency of the kitchen hood decreases, increasing the amount of harmful contaminants remaining in the kitchen.

A recent study has shown that most kitchen hood owners do not regularly maintain or clean their kitchen hoods. However, when the kitchen hood is not properly maintained, oil that accumulates under the kitchen hood or remains in the air can be caused by Staphylococcus aureus ("staph"), Escherichia coli ("E. coli" (E) coli) and Streptococcus pneumoniae (which can cause meningitis, pneumonia, sinus infections and other infections). Harmful substances produced during cooking, such as , carbon monoxide, nitrogen dioxide, formaldehyde, volatile organic compounds, black carbon, and polycyclic aromatics hydrocarbons, can spread throughout the kitchen. This can be dangerous and can further reduce the efficiency of the kitchen hood.

In the kitchen, harmful gas containing 15-40 nm particles generated during cooking is condensed with oil to generate fine dust of 1 to 10 μm. For example, Table 1 below lists hazardous substances such as gases and/or volatile organic compounds that occur during cooking.

matter cause danger fine dust Caused by condensation of moisture and oil on the initial particles formed on the food surface enters the lungs through the respiratory tract, weakens lung function and weakens immunity; Group 1 carcinogens nitrogen dioxide Occurs due to incomplete combustion of food ingredients Respiratory diseases such as reduced oxygen carrying capacity of hemoglobin and high concentration bronchitis formaldehyde Formaldehyde is generated by incomplete combustion in the combustion process of organic matter. skin irritation such as eyes, nose, and throat; Headache, vomiting and shortness of breath with prolonged exposure; carcinogen volatile organic compounds Occurs when oil is heated Respiratory damage, eye irritation, headache, skin irritation; chronic blood loss, anemia polycyclic aromatic hydrocarbons Incomplete combustion of oils caused by carbonization of carbohydrates, fats, and proteins respiratory diseases and DNA modifications; Class 1 carcinogen Black carbon (soot) Occurs due to incomplete combustion of food ingredients Respiratory diseases

Initial particles (volatile organic compounds and harmful substances such as nitrogen dioxide) with a size of about 15-40 nm are generated during food cooking, and when combined with water and oil, the size of these particles increases to make fine dust. Harmful gases generated during cooking are coated with oil vapor or mist. Vapors containing harmful gases, once accumulated in a room, are not easily removed and remain indoors for a long time. WO 201709534 A1 discloses an automatically moving kitchen hood having a protrusion installed behind a stove or a suction port resembling a faucet. Upon sensing a heat source, the suction port moves over the heat source. The suction port may move in the left and right directions, and cover only one cooking vessel. Since the kitchen hood is installed on the floor behind the stove instead of the wall or the ceiling, it may be difficult to install, and harmful gas may not be emitted to the outside.

Meanwhile, another embodiment is shown in FIG. 24 . In this embodiment, the first flow path fan 900 and the second flow path fan 900 ′ may be additionally installed inside the second housing 200 . The first flow fan 900 and the second flow fan 900 ′ may be, for example, axial fans. The first flow path fan 900 and the second flow path fan 900 ′ may be respectively installed in the flow path formed inside the second housing 200 or at a position corresponding to the flow path.

For example, as shown in FIG. 25 , among the flow paths of the second housing 200 , the second housing 200 is disposed on the left side flow path opened and closed by the damper 660 on the left side (when the second housing 200 is viewed from the front). One euro fan 900 may be installed. A second flow path fan 900 ′ may be installed in the right flow path opened and closed by the damper 660 on the right side of the flow path of the second housing 200 . An axial fan may be used for the first flow fan 900 and the second flow fan 900 ′. The axial fan may occupy an area having a predetermined radius in a radial direction with respect to the axis of rotation. In this embodiment, the cross-sectional shape of the flow path opened and closed by the damper 600 on the left side is rectangular. Accordingly, if the cross section of the flow path is divided into a plurality of square regions, one flow path fan 900 , 900 ′ may be installed in each of the square regions.

Accordingly, as can be seen from the drawings, in this embodiment, a plurality of first flow path fans 900 or second flow path fans 900 ′ may be installed on one flow path. In this embodiment, when the kitchen hood 1 sucks in air in the kitchen and discharges it to the outside, two flow paths are employed. At least one first flow path fan 900 may be installed in one of the two flow paths, and at least one second flow path fan 900 ′ may be installed in the other flow path.

In the drawing, a plurality of first flow path fans 900 are installed in a row on the left flow path, and a plurality of second flow fan 900 ′ are installed in a row on the right flow path. However, one first flow path fan 900 may be installed in the left flow path and one second flow fan 900 ′ may be installed in the right flow path. Using a plurality of each of the first flow fan 900 and the second flow fan 900 ′ is to further increase the ability to suck air. Accordingly, depending on design conditions, at least one of the first flow path fan 900 and the second flow path fan 900 ′ may be used in each flow path.

The position at which the first flow path fan 900 and the second flow path fan 900 ′ are installed on each flow path is below the lowermost one among the tabs 651 of the condensate collector 650 and the damper 600 ) between the leading ends. However, alternatively, the first flow path fan 900 and the second flow path fan 900 ′ may be positioned between the damper 660 and the suction grill 210 . Alternatively, the first flow path fan 900 and the second flow path fan 900 ′ may be positioned above the tab 651 in the condensate collector 650 . Although the inside of the condensate collector 650 is a part where two flow paths formed inside the second housing 200 merge, the first flow path fan 900 and the second flow path fan 900' are located adjacent to each flow path. ), it is possible to generate the flow of air through each flow path.

As described above, the first flow path fan 900 and the second flow path fan 900 ′ may generate air flows in the flow paths formed inside the second housing 200 , respectively. In this embodiment, the fan 300 and the first flow path fan 900 and the second flow path fan 900 ′ may be used at the same time. However, instead of using the fan 300 , the air flow in the kitchen hood 1 may be created by using the first flow path fan 900 and the second flow path fan 900 ′. That is, as another embodiment, without the fan 300 , only the first flow path fan 900 and the second flow path fan 900 ′ may be employed for air flow.

28, it is disclosed that a first flow fan 910 and a second flow fan 910', which are crossflow fans, are used. The first flow path fan 910 and the second flow path fan 910 ′ used here are cross-flow fans extending long in one direction in a cylindrical shape, as shown in an enlarged view in the drawing, so the inside of the second housing 200 is One of each may be located in the flow passage having a rectangular flow cross-section.

Here again, the first flow path fan 910 and the second flow path fan 910 ′ may be installed in a flow path between the tab 651 and the damper 660 . However, positions at which the first flow path fan 910 and the second flow path fan 910 ′ are installed may be set in various ways. For example, the first flow path fan 910 and the second flow path fan 910 ′ may be respectively positioned between the damper 660 and the suction grill 210 . Also, a first flow path fan 910 and a second flow path fan 910 ′ may be positioned inside the condensate collector 650 corresponding to an upper portion of the tab 651 .

In FIGS. 24 to 28 , the flow of air by the fan 300 , the first flow path fans 900 and 910 , and the second flow path fans 900 ′ and 910 ′ will be described. First, the fan 300 may be used for basic air intake in the kitchen hood 1 . The flow path fans 900.900 ′ and 910.910 ′ may be used to enhance air suction power when the second housing 200 descends and the flow path lengthens in the kitchen hood 1 .

When the second housing 200 comes out of the first housing 100 and comes closest to the cooktop, the length of the flow path inside the kitchen hood 1, that is, from the suction grill 210 to the fan 300 length is maximized. In this case, the suction force of the fan 300 is inevitably weakened relatively in the suction grill 210 . At this time, the first flow path fans 900 and 910 and/or the second flow path fans 900'.910' may operate to increase suction power to smoothly suction and discharge air. The first flow path fans 900 and 910 and the second flow path fans 910 and 910 ′ may be operated simultaneously or separately.

In this embodiment, the operations of the fan 300 , the first flow path fans 900 , 910 , and the second flow path fans 900 ′ and 910 ′ are automatically controlled based on the sensed by the air quality sensor assembly 500 . can be The controller may have a memory for storing predetermined quantities and densities of the sensing target. When the amount or density sensed by the air quality sensor assembly 500 is greater than or equal to the predetermined amounts and the density, respectively, the fan 300 is turned on or the speed of the fan 300 is increased by the predetermined fan speed amount can be increased by

The second housing 200 may be raised or lowered to optimize the air flow based on what is sensed by the air quality sensor assembly 500 . For example, after cooking is complete and when there is no cookware, the second housing 200 may be lowered and the fan 300 may be moved at a predetermined speed, such as a maximum speed, to reduce residual contaminants. can work Alternatively, if other undesirable substances are detected in the kitchen (eg during microwave cooking or roasting), the second housing 200 can be lowered by a predetermined amount (eg a maximum amount) or The fan 300 may be operated at a predetermined speed (eg, maximum speed) to exhaust contaminants, including contaminants, from devices in the kitchen and/or to improve air quality in the home.

In addition, the first flow path fans 900 and 910 and the second flow path fans 900 ′ and 910 ′ may be operated based on values sensed by the air quality sensor assembly 500 and the sensor assembly 700 . When the second housing 200 descends and the suction force of the fan 300 acting on the suction grill 210 becomes relatively small, the first flow path fans 900 and 910 and the second flow path fans 900 ′ and 910 ') may work. In addition, when the flow path requiring air intake is the left flow path, the first flow path fans 900 and 910 may operate, and if the flow path requiring air suction is the right flow path, the second flow path fans 900 ′ and 910 ′ may operate. Of course, when air is sucked through both the right flow path and the left flow path, both the first flow path fans 900 and 910 and the second flow path fans 900 ′ and 910 ′ may be simultaneously operated.

29 to 32 show another embodiment of the kitchen hood. In this embodiment, the fan 300 ′ for sucking air may be raised and lowered together with the lifting of the second housing 200 . In other words, the fan 300 ′ moves integrally with the second housing 200 . Accordingly, the distance from the fan 300 ′ to the suction grill 210 may be constantly maintained regardless of whether the second housing 200 is raised or lowered.

The fan housing 310 ′ of the fan 300 ′ may be located at an upper end of the inner surface of the second housing 200 . 31 , the fan housing 310 ′ may be mounted inside the upper end of the second housing 200 . When the fan housing 310' is mounted at this position, the steam distributor 670 may be provided under the fan housing 310'.

In this embodiment, when the second housing 200 is in a relatively low position, the opening of the first housing upper frame 140 through which air is discharged from the fan 300 ′ to the outside of the first housing 100 . The distance to (141a, 142a) may vary. As such, when the distance from the fan 300 ′ to the openings 141a and 142a is changed, in particular, the second housing 200 descends and the air leaving the second housing 200 moves to the opening 141a. can be relatively long. In this case, the air may spread from the inside of the first housing 100 and the air may not be smoothly transferred to the openings 141a and 142a.

In order to prevent this, an expansion duct 320 for transferring air from the fan housing 310 ′ of the fan 300 ′ to the openings 141a and 142a of the first housing upper frame 140 may be installed. there is. The expansion duct 320 is that air flows through the inside. The stretchable duct 320 may be stretched in length. The expansion duct 320 may be a flexible hose made of a flexible material. When the second housing 200 is lowered, the telescopic duct 320 is elongated, and when the second housing 200 is raised and accommodated in the first housing 100, the telescoping duct 320 is reduced. It may be positioned between the first housing upper frame 140 of the first housing 100 and an upper end of the fan housing 310 ′.

The upper end of the expansion duct 320 may be connected to the edges of the openings 141a and 142a among the bottom surfaces of the first housing upper frame 140 , or more precisely, the second upper frame 142 . The outlet of the expansion duct 320 may communicate with the openings 141a and 142a, and air may be discharged through the openings 141a and 142a. If discharge through the upper portion of the first housing 100 is not possible, the upper end of the expansion duct 320 may be connected to the outside through the rear surface or the side surface of the first housing 100 .

In the present embodiment, when the fan 300 ′ is operated, air in the kitchen may be sucked through the suction grill 210 spanning both sides and the lower surface of the second housing 200 . That is, air may be sucked in by the fan 300 ′ through flow paths separately formed on the left and right sides of the second housing 200 .

The flow path formed on the inner left side of the second housing 200 may be opened and closed by the left damper 660L, and the flow path formed on the inner right side may be opened and closed by the right damper 660R. Suction may be performed by the fan 300'.

Accordingly, air may be sucked into the kitchen hood 1 and discharged to the outside through two flow paths with one fan 300 ′ or through a selected one flow path. The intake of air through the suction grills 210 on both sides of the second housing 200 may be controlled by the sensing value of the air quality sensor assembly 500 and/or the sensor assembly 700 .

When the air in the kitchen is sucked by using at least one of the suction grills 210 on the left and right sides of the second housing 200 as in this embodiment, the air is sucked at a location closer to the location of the pollution source. This can be done. That is, when there is a pollution source on the left side of the second housing 200, air is sucked into the second housing 200 through the suction grill 210 on the left side of the second housing 200 by suction of the fan 300'. 200) can be inhaled. When there is a contamination source on the right side of the second housing 200, air is sucked into the second housing 200 through the suction grill 210 on the right side of the second housing 200 by suction of the fan 300'. can be inhaled internally. In this way, since air is sucked by the fan 300 ′ in a state closer to the pollution source, more efficient air discharge may be possible.

29 and 31 show a state in which the second housing 200 is extended from the first housing 100 and air can be sucked by the fan 300 ′. When the fan 300 ′ is operated, air is sucked through the suction grills 210 on both sides of the second housing 200 , and the air is sucked through the two flow paths formed in the inner housing 200 . ) can be transferred. The air delivered to the fan 300 ′ may flow into the expansion duct 320 , and the air passing through the expansion duct 320 may be discharged to the outside of the first housing 100 .

32 shows a state in which the second housing 200 is completely accommodated in the first housing 100 . In this state, the fan 300 ′ may rise together with the second housing 200 to be located inside the upper end of the first housing 100 . As the fan 300' rises, the fan housing 310' also rises, so that the expansion duct 320 has the shortest length.
