Description

Technology Field

[0001] The present invention relates to an oil collection cap for an exhaust hood, and more specifically, it is designed to provide a pleasant indoor environment by reducing the area of ​​the smoke exhaust passage moving to the lower inlet of the hood pipe and forming guide vanes, thereby maximizing both the exhaust efficiency due to the cyclone effect and the oil collection efficiency contained in the oil vapor. Background Technology

[0002] Generally, when grilling meat using a grill pan in places like restaurants, a large amount of fuming smoke is generated.

[0003] Since the smoke contains a large amount of oil and odor, restaurants install an exhaust hood above the grill plate to quickly exhaust the smoke when grilling meat. A duct system is installed to rapidly draw in the smoke generated from the grill plate and expel it to the outside.

[0004] The exhaust hood consists of a hood pipe extending vertically from a main duct connected to an exhaust fan, an oil drip cap attached to the bottom of the hood pipe, and a filter seated on top of the oil drip cap.

[0005] The filter is made of a mesh structure so that oil components contained in the passing oil vapor adhere to the mesh and are then collected.

[0006] The hood tube is in the form of a metal tubular structure with an open bottom, and the expanded section is formed at an angle to account for the diameter of the oil catcher cap assembled at the bottom.

[0007] The oil drip cap is shaped like a container with a sealed bottom and is detachably attached to the bottom of the hood tube, and intake holes are drilled in the bottom plate.

[0008] Therefore, as the exhaust fan operates, the smoke generated when grilling meat using the grill plate is sucked into the interior of the hood pipe through the intake hole of the grease tray cap, and then the smoke is discharged to the outside.

[0009] At this time, some of the relatively light particulate oil contained in the smoke is discharged outdoors through the hood pipe, and some of the heavy oil adheres to the inner wall of the hood pipe, then flows downward along the hood pipe and is collected inside the oil catcher cap.

[0010] In conventional exhaust hoods, a structure has been proposed in which a separate cap or container-shaped cover is attached to the upper side of the intake hole to prevent some of the oil from falling onto the grill plate located below through the intake hole formed in the oil catcher cap.

[0011] However, if a separate oil drip cover is installed over the intake port, the flow of inhaled smoke is obstructed, reducing exhaust efficiency.

[0012] Meanwhile, smoke drawn in through the intake hole of the oil tray cap must move upward along the hood pipe with a relatively wide area, but even if the suction force of the blower provided in the exhaust duct is applied, the suction force is weak when the inner diameter area of ​​the hood pipe is large.

[0013] In addition, since the area over which the smoke is transported is wide, there was a problem where the transport speed was slow and the overall smoke exhaust efficiency was reduced.

[0014] As such, when the efficiency of smoke exhaust from the meat combustion process decreases, the interior environment of the restaurant becomes unpleasant, and it causes severe odors to cling to users' clothes or harm their health. Prior art literature

[0024] delete Effects of the invention

[0025] According to the present invention, a cyclone effect can be achieved by installing a guide section to reduce the smoke movement area on the inner side of an expanded section that is formed at an angle for assembling an oil catcher cap at the lower inlet side of the hood tube, and by installing guide wings on this guide section.

[0026] Therefore, as the smoke exhaust speed is improved, the intake volume increases significantly, making it possible to maintain a pleasant indoor environment, such as restaurants where a lot of smoke is generated.

[0027] In addition, by guiding the oil towards the oil receiving groove with the guide vanes to ensure smooth collection, it prevents air pollution through improved oil collection efficiency and enhances the convenience of oil collection and cleaning. Furthermore, oil collection efficiency is improved by molding the moving groove concavely so that the fallen oil can move smoothly to the oil receiving groove. Brief explanation of the drawing

Specific details for implementing the invention

[0029] The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0030] However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms, and these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0031] Furthermore, the terms used in this specification are for describing the embodiments and are not intended to limit the invention.

[0032] In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As used in this specification, "comprises" and / or "comprising" do not exclude the presence or addition of other components other than those mentioned.

[0033] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning that is commonly understood by those skilled in the art to which the present invention belongs.

[0034] Hereinafter, in order to explain the present invention more specifically, embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0035] As shown in the drawing, the oil catch cap (100) of the exhaust hood of the present invention is formed in a structure in which ribs (50) are connected to each other, connecting the rim portion (10), the oil catch groove (20), and the guide portion (30) which is positioned inside the expansion portion (2) and reduces the area of ​​the movement passage.

[0036] The guide section (30) is positioned inside the expansion section (2), which is formed at an angle at the lower entrance of the hood tube (1), thereby forming a smoke passage (31) between them. This guide section (30) is mounted at the lower entrance of the hood tube (1) and is installed inside the expansion section (2), which is angled downward and expands downward, and has a conical shape while sloping upward from the bottom. A void space is formed between the outer surface of the guide section (30) and the inner surface of the expansion section (2). This void space forms a smoke passage (31) through which the inhaled smoke flows from the bottom upward. Consequently, the inclined surface of the induction section (30) and the inclined surface of the expansion section (2) form the smoke passage (31). If the inclined surface of the induction section (30) is formed more steeply than the inclined surface of the expansion section (2), the smoke passage (31) becomes narrower as it rises upward, thereby achieving the effect of increasing the speed of movement of the inhaled smoke. Additionally, it is preferable to form a plurality of guide wings (40) on the outer surface of the induction section (30). It is preferable that the guide wings (40) be installed in a round shape, winding from bottom to top along the inclined surface of the induction section (30). This is intended to provide a cyclone effect by causing the guide wings (40) to rotate the inhaled smoke rising from below in a circular motion and simultaneously rotate it in a narrowed concentric circle. The above guide wings (40) can be installed in numbers of 2 to 6, and more preferably 3 or 4.

[0037] Accordingly, by reducing the area of ​​the smoke passage (31) by the induction section (30) and forming multiple guide wings (40) around it, the smoke is rotated at a high speed due to the cyclone effect, thereby increasing the exhaust efficiency.

[0038] Additionally, the oil contained in the oil vapor is gradually moved downward along the guide wing (40) after hitting the guide wing (40) and then collected in the oil receiving groove (20) connected to the rib (50).

[0039] FIG. 1 is a perspective view showing the structure of a hood oil catcher cap according to the present invention, and FIG. 3 is a cross-sectional view showing the state in which it is fitted and assembled into the inner side of the inlet portion of the hood tube (1).

[0040] The hood tube (1) is in the shape of a metal tube and is connected in an up-and-down direction, mainly taking into account the position of the grill plate, so that smoke sucked in by the exhaust fan can be discharged to the outside.

[0041] At the bottom of this hood tube (1), an expanded section (2) is formed at an angle so that an oil catcher cap (100) with a larger diameter can be assembled.

[0042] The oil catcher cap (100) is connected to the oil catcher groove (20) through ribs (50) around a guide section (30) that is installed in a conical shape from the center of the bottom toward the top, and smoke intake holes (51) are drilled between the ribs (50) so that oil vapor (smoke) generated from the grill plate can be sucked in and discharged to the outside through the main duct.

[0043] A catch groove (3) is provided on the lower side of the expanded portion (2) of the hood tube (1) so that the rim portion (10) can be attached and detached relatively easily, and a catch projection (11) is molded to protrude inwardly from the rim portion (10) so that it is fitted into the catch groove (3) and fixed.

[0044] Therefore, by inserting the locking projection (11) into the locking groove (3) position and then rotating it at a certain angle, the oil catch cap (100) can be maintained in an assembled state at the lower part of the hood tube (1).

[0045] FIGS. 1 to 6 illustrate the configuration of an oil catcher cap (100) according to a preferred embodiment of the present invention.

[0046] That is, the oil catcher cap (100) is largely composed of a rim portion (10), an oil catcher groove (20), a guide portion (30), a guide wing (40), and ribs (50) connecting the guide portion (30) and the oil catcher groove (20).

[0047] The above-mentioned rim portion (10) is formed into a cylindrical shape to be fitted into the end portion of the hood tube (1), and a concave oil collecting groove (20) is provided on the inner lower side to collect fallen oil.

[0048] A cone-shaped guide (30) is positioned in the center of the oil receiving groove (20) facing upward, and the lower part of the oil receiving groove (20) and the guide (30) are connected by a plurality of ribs (50) with a gap maintained so that a smoke suction hole (51) is formed.

[0049] Here, a convex member (32) with a curved surface facing downward is attached and fixed to the bottom surface of the guide section (30) to guide the smoke moving from below toward the smoke passage (31).

[0050] The above-mentioned guide section (30) is formed with a conical upper section that is inclined to be roughly the same as the slope of the expansion section (2) or so that the smoke passage gradually narrows toward the top.

[0051] Accordingly, between the expansion section (2) and the guide section (30) of the hood pipe (1), the area where smoke can move is narrowed compared to the case where the guide section (30) is not installed, resulting in a faster flow rate.

[0052] In other words, when a fluid passes through a narrow space, its pressure decreases and its speed increases (Bernoulli's principle).

[0053] Additionally, a plurality of guide wings (40) are installed in the guide section (30) to rotate the smoke flowing in from the smoke passage (31) and moving upward, and to guide the collected oil components to move downward by their own weight.

[0054] In this way, the smoke introduced into the inlet of the hood tube (1) by the induction section (30) and the guide wing (40) rotates rapidly and rises due to the cyclone effect, which greatly increases the smoke suction effect, thereby allowing the indoor environment of restaurants where a lot of meat is grilled to be kept pleasant.

[0055] Additionally, the oil components contained in the oil vapor are moved by the guidance of the guide vane (40) by its own weight after striking the guide vane (40) or contacting the guide part (30), and after descending, are collected in the oil collecting groove (20) along the rib (50). (Fig. 5)

[0056] At this time, it is preferable that the lower part of the guide wing (40) be positioned at the center of one of the ribs (50) so that the oil component falling along the guide wing (40) can be moved directly to the oil receiving groove (20) through the ribs (50).

[0057] In addition, the rib (50) is formed with a concave moving groove (52) so that the fallen oil can move smoothly to the position of the oil receiving groove (20), thereby improving the oil collection efficiency. (Fig. 6)

[0058] In this way, oil is guided to the oil catcher groove (20) through the guide wings (40) and ribs (50), thereby protecting the grill plate from falling oil components from the hood tube (1) during the cooking process.

[0059] According to the configuration of the oil catcher cap (100) of the present invention, the smoke discharge speed is fast and the amount of indoor smoke inhaled is greatly increased, so that the indoor environment, such as a restaurant, can be maintained comfortably.

[0060] In addition, improved oil collection efficiency prevents air pollution and enhances the convenience of oil collection and cleaning.

[0061] The present invention described above is not limited by the aforementioned embodiments and drawings, and it will be obvious to those skilled in the art that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
