Description

Cooking appliances

[0001] Embodiments of the present invention relate to a cooking appliance, and more specifically, to a cooking appliance that provides a function of sucking up and removing contaminants generated during the cooking process.

[0002]

[0003] Generally, kitchens are equipped with cooking surfaces fitted with heating appliances such as electric heaters or gas stoves, which are used for heating and cooking food.

[0004] During the heating and cooking process, the food being cooked generates pollutants such as smoke, odors, and oil vapors, which can become airborne due to the heat and spread throughout the entire room. This results in unpleasant odors and, particularly in enclosed kitchen environments, can impair worker concentration and cause health problems.

[0005] Accordingly, a range hood is installed in the kitchen to exhaust contaminants generated during the cooking of food to the outside. The range hood includes a hood body with an intake port formed on its lower surface and a suction fan that generates an airflow to draw air into the hood body and discharge it to the outside. Additionally, the range hood further includes a filter installed in the hood body to filter the air drawn into the body and a pipe that forms a passage to discharge the air drawn into the body through the filter to the outside.

[0006] Contaminants generated during the heating of food on the countertop rise due to their own buoyancy caused by their temperature being higher than the surrounding air, or are forcibly lifted by the airflow formed by the suction fan. The risen contaminants pass through a filter and are discharged into an external duct via piping.

[0007] However, while a range hood can suck up contaminants near the intake port of the hood body to some extent, it is difficult to properly suck up contaminants located far from the intake port. This is because the velocity of the intake airflow decreases inversely proportional to the square of the distance from the intake port as it moves further away. In other words, in conventional range hoods, suction performance deteriorates rapidly as it moves further away from the intake port, and even if the airflow of the intake fan is increased, the efficiency of capturing contaminants is not sufficiently improved.

[0008] However, while it is possible to consider increasing the suction power by increasing the airflow of the suction fan, doubling the airflow increases power consumption by about eight times, which leads to a problem of significantly increased power consumption and noise.

[0009] Therefore, the closer the air intake is positioned to the source of contaminants, the higher the capture effect; to this end, the range hood should be installed so that the intake is located as close as possible to the point where the food is heated. However, optimizing the installation height of the range hood is difficult due to the trade-off between contaminant capture efficiency and cooking efficiency.

[0010] In other words, while pollutant capture efficiency improves as the installation height of the range hood decreases, there is a problem in that only low-height cooking appliances that can be placed on the countertop can be used. Conversely, as the installation height of the range hood increases, tall cooking appliances can be used, but there is a problem in that the distance between the pollutant source and the intake vent increases, leading to a decrease in pollutant capture efficiency.

[0011]

[0012] The objective of the present invention is to provide a cooking appliance with optimized air intake direction and flow path shape so as to efficiently capture contaminants generated during cooking.

[0013] In addition, another objective of the present invention is to provide a cooking device that improves both suction and purification efficiency by minimizing airflow resistance while stably securing the suction performance of the fan.

[0014] In addition, another objective of the present invention is to provide a cooking device that ensures the stability and reliability of airflow by controlling contaminants generated during cooking to flow consistently along a set path.

[0015] The objectives of the present invention are not limited to those mentioned above, and other objectives and advantages of the present invention not mentioned may be understood from the following description and will be more clearly understood by the embodiments of the present invention.

[0016]

[0017] A cooking device according to one embodiment of the present invention is characterized by drawing in air that has flowed into a component placement space through an opening formed in a top plate through an intake port, and delivering the drawn-in air to a fan through an inlet path and a plurality of branched connecting paths.

[0018] In addition, a cooking device according to one embodiment of the present invention is characterized in that a first filter and a second filter are sequentially arranged upstream of the intake port of a fan, so that the air undergoes a multi-stage purification process before reaching the fan.

[0019] In addition, a cooking device according to one embodiment of the present invention is characterized in that a first filter is formed in a cylindrical shape and a plurality of second filters are provided in an annular segment shape, so that air is diffused radially inside the first filter and then dispersed and introduced through the plurality of second filters.

[0020] In addition, a cooking device according to one embodiment of the present invention is characterized by having a filter receiving portion provided inside a flow guide so that a second filter is stably supported.

[0021] In addition, a cooking device according to one embodiment of the present invention is characterized in that one side of a second filter is supported by a filter support and the other side is in contact with the inner surface of a flow guide, so that air flows only along the connecting flow path without passing through the gap inside the flow guide.

[0022] A cooking device according to one aspect of the present invention may include a top plate having an opening formed therein that covers a component placement space and opens the component placement space; a fan having at least a portion disposed in the component placement space and sucking in air introduced through the opening; and a flow guide disposed in the component placement space and having a flow path formed therein that transmits the air sucked in through the opening to the fan. Here, the flow path includes an inlet flow path communicating with the opening and a connecting flow path that transmits the air flowing in the inlet flow path to the fan, and the connecting flow path may be branched into a plurality of sections.

[0025] In addition, the inlet channel is formed in a vertical direction, and the branched connecting channel transmits air flowing vertically through the inlet channel in a horizontal direction, and the fan can discharge air sucked in vertically through the intake port in a horizontal direction.

[0026] Additionally, the cooking device may further include a first filter that is partially accommodated inside the above-mentioned flow guide and disposed on the inlet flow path, and a plurality of second filters that are accommodated inside the above-mentioned flow guide, are provided between the first filter and the fan, and are each disposed on the branched connecting flow path.

[0027] Additionally, the opening may have a circular shape, the first filter may have a cylindrical shape with an open top surface communicating with the opening, and each of the plurality of second filters may have an annular segment shape with respect to the center of the first filter.

[0028] In addition, each of the plurality of second filters may be arranged to surround a portion of the outer surface of the first filter.

[0029] In addition, the air flowing through the inlet path may not be delivered to the fan through the remaining portion, excluding a portion of the outer surface of the first filter.

[0030] In addition, the Euro guide is provided with a filter receiving portion for accommodating the first filter and the plurality of second filters, and the filter receiving portion may include a filter support portion that supports each of the plurality of second filters within the Euro guide.

[0031] Additionally, one side of each of the plurality of second filters may be supported in the vertical direction by the filter support, and the other side of each of the plurality of second filters may be arranged to be in contact with the inner surface of the flow guide.

[0032] Additionally, the filter receiving portion further includes a filter mounting portion formed corresponding to each of the plurality of second filters, wherein the filter mounting portion includes a first filter mounting portion formed protrudingly to mount the inner surface of the second filter facing the first filter, and a second filter mounting portion formed protrudingly to mount the outer surface of the second filter facing the inner surface of the second filter, and the second filter mounting portion may be arranged to be in contact with the inner circumferential surface of the flow guide.

[0033] Additionally, the plurality of second filters may include a first second filter that surrounds a portion of the outer surface of one side of the first filter and a second filter that surrounds a portion of the outer surface of the other side of the first filter, and the branched connecting channel may include a first connecting channel in which the first second filter is disposed and a second connecting channel in which the second filter is disposed.

[0034] Additionally, the first connecting channel may be formed based on one side outer surface of the first filter, the one side second filter, and one side inner surface of the channel guide, and the second connecting channel may be formed based on the other side outer surface of the first filter, the other side second filter, and the other side inner surface of the channel guide.

[0035] Additionally, the outer region of the first filter is composed of a first outer region in which the first and other second filters surround the first filter, and a second outer region other than the first outer region, and a filter support member may be formed in a part of the second outer region adjacent to the fan among the second outer regions to support one side of each of the first and other second filters.

[0036] Additionally, the other side of the first second filter is positioned to be in contact with a first part of the inner circumference of the flow guide, and the other side of the second filter is positioned to be in contact with a second part of the inner circumference of the flow guide, and another part of the second outer region among the second outer regions may be formed based on the other side of each of the first and second filters, the outer circumference of the first filter, and the inner circumference of the flow guide that continuously connects the first part and the second part.

[0037] In addition, by the formation of the filter support member disposed in a part of the second outer region and another part of the second outer region, air introduced into the first filter through the inlet channel can flow only through the first and second connecting channels.

[0038]

[0039] According to the present invention, air introduced through the opening of the top plate can be delivered to the fan through a plurality of branched connecting passages. Accordingly, the effective cross-sectional area required for the fan to inhale air is increased, and the air supply to the fan is evenly distributed, thereby improving the fan's suction performance.

[0040] Furthermore, according to the present invention, by sequentially arranging a first filter and a second filter on the upstream side of the fan's intake port, contaminated air can undergo a multi-stage purification process before entering the fan. Accordingly, the cleanliness of the air entering the fan is enhanced, and the direct attachment of contaminants to the fan's impeller and other components can be prevented. In addition, the efficiency of capturing contaminants can be effectively improved without increasing the fan's intake airflow velocity, and noise can be suppressed.

[0041] In addition, according to the present invention, a first filter may be provided in a cylindrical shape, and a plurality of second filters disposed in a branched connecting channel may be formed in an annular segment shape. Accordingly, air diffuses radially within the first filter and then disperses into the plurality of second filters, thereby facilitating the smooth flow of air and ensuring uniform collection efficiency.

[0042] In addition, according to the present invention, a filter receiving portion is formed inside a flow guide in which a connecting flow path is formed, so that a second filter can be stably fixed. Accordingly, a constant air flow path is secured, and since the second filter does not shake, stable collection performance can be secured for a long period of time.

[0043] In addition, according to the present invention, one side of the second filter is supported by a filter support, and the other side of the second filter is positioned to be in contact with the inner surface of the flow guide, thereby blocking the leakage of contaminated air through the gap inside the flow guide and allowing the contaminated air to flow only through the connected flow path. Accordingly, the air flow must pass through the second filter, thereby improving purification efficiency.

[0044] In addition to the effects described above, the specific effects of the present invention are described together with the specific details for implementing the invention below.

[0068] FIG. 1 is a drawing showing the installation state of a cooking device (1) according to one embodiment of the present invention. FIG. 2 is a drawing showing a front perspective view of the cooking device (1) of FIG. 1. FIG. 3 is a drawing showing a rear perspective view of the cooking device (1) of FIG. 1. FIG. 4 is a drawing showing the state in which the top plate (10) is removed from the cooking device (1) of FIG. 2.

[0069] Referring to FIGS. 1 to 4, a cooking device (1) according to one embodiment of the present invention can be installed on a support (2).

[0070] The support member (2) may be a structure for installing or fixing the components of the cooking appliance (1), and a space capable of accommodating at least a part of the cooking appliance (1) may be formed inside the support member (2). The support member (2) may be provided in a predetermined cabinet structure. For example, the support member (2) may be provided in the form of a lower cabinet on which a cooking surface (2a) is formed, and the cooking appliance (1) may be installed on the cooking surface (2a).

[0071] According to the present embodiment, a part of the cooking device (1), for example, a top plate (10), may be exposed to the upper side of the cooking table (2a), and the remaining part of the cooking device (1) may be inserted into a support (2) and positioned to the lower side of the cooking table (2a).

[0072] Meanwhile, according to another embodiment, the cooking device (1) may be configured to further include a case, and the cooking device (1) including the case may be placed on the upper side of the cooking table (2a).

[0073] The cooking device (1) may include a heating device and an exhaust device. The heating device can heat a body to be heated, such as a container containing food, and the exhaust device can collect contaminated air, such as smoke, steam, and contaminants, generated when the body to be heated is heated.

[0074] In this embodiment, a heating device in the form of an electric range is exemplified. Here, the term "electric range" encompasses both electric resistance ranges and induction heating ranges. For convenience of explanation, embodiments of the present invention will be described focusing on an electric range equipped with a working coil as a heating element. However, the present invention is not limited thereto.

[0075] The heating device may include a top plate (10), a heating unit case (15), at least one heating section (20), and an electrical section (30).

[0076] The top plate (10) can be placed on the upper part of the heating device to form the upper surface of the cooking device (1). The top plate (10) can accommodate a body to be heated. For example, the top plate (10) can be made of ceramic glass and can be formed into a flat plate shape with thickness.

[0077] A component placement space (S, see FIG. 7, 8) may be provided vertically below the top plate (10).

[0078] The component placement space (S) may be an area where internal components of the cooking appliance (1) are placed. Conceptually, the component placement space (S) may be defined as an internal area enclosed by virtual vertical walls that extend vertically along the horizontal outline of the top plate (10).

[0079] That is, the upper part of the component placement space (S) can be covered by a top plate (10), and the side and lower parts of the component placement space (S) can be open and not structurally completely enclosed by a wall. Therefore, the component placement space (S) can be defined not as a closed chamber, but as an abstract spatial concept in which components are functionally placed inside the cooking appliance (1).

[0080] The heating unit (20) can heat the object to be heated. For example, as shown in FIG. 4, the heating unit (20) may include a working coil positioned on the lower side of the top plate (10). In another example, the heating unit (20) may include a hot plate that heats the metal plate itself by placing an electric heating wire on the lower side of the metal plate. In yet another example, the heating unit (20) may include a highlight that directly heats the top plate (10) using an infrared radiating ceramic heater. In yet another example, the heating unit (20) may include two or more of the working coil, the hot plate, and the highlight.

[0081] The heating unit case (15) can accommodate various components constituting a heating device, such as a working coil corresponding to a heating part (20). The open top of the heating unit case (15) is covered by a top plate (10), and the heating unit case (15) can be formed in a polygonal shape with an open top.

[0082] The electrical unit (30) can accommodate electrical components related to the operation of the heating unit (20). The electrical unit (30) can be positioned on the lower side of the top plate (10) and the heating unit case (15).

[0083] The electrical unit (30) may include an electrical case (31). According to the present embodiment, the electrical case (31) may be formed in a polygonal shape with an open top. The open top of the electrical case (31) is covered by a heating unit case (15), and various electrical components may be accommodated inside the electrical case (31).

[0084] For example, at least one of the heating unit case (15) and the electrical case (31) may be formed in the shape of a square box made of aluminum, but the present invention is not limited thereto. Additionally, at least one of the heating unit case (15) and the electrical case (31) may be insulated to prevent the temperature of the outer surface from rising due to heat generated by the heating unit (20) or heat generated by the electrical components.

[0085] An opening (12) may be formed in the top plate (10). The opening (12) may be formed in the shape of a hole penetrating the top plate (10) in the vertical direction, and may form a passage for opening a component placement space (S) on the upper side of the top plate (10).

[0086] According to the present embodiment, the opening (12) may be circular in shape and may be formed in the central region of the top plate (10).

[0087] The exhaust device is positioned adjacent to the heating device to collect contaminated air generated when the object to be heated is heated and discharge it to the outside of the cooking device (1). The exhaust device may be positioned in a component placement space (S) corresponding to the lower space of the top plate (10).

[0088] The exhaust device may include a fan (40), a filter (50), and a Euro guide (60).

[0089] The structure of the exhaust system is explained in more detail below.

[0090]

[0091] [Overall structure of the exhaust system]

[0092] FIG. 5 is a front perspective view of an exhaust device according to an embodiment of the present invention. FIG. 6 is a drawing showing the state in which the fan cover (47) and guide housing (61) are removed from the front perspective view of the exhaust device of FIG. 5. FIG. 7 is a rear cross-sectional view of the exhaust device of FIG. 5. FIG. 8 is a right side cross-sectional view of the exhaust device of FIG. 5.

[0093] Meanwhile, in FIGS. 7 and 8, for convenience of explanation, the top plate (15) and the heating unit case (15) are included, and the electrical unit (30) is omitted.

[0094] Hereinafter, the internal structure of the exhaust device will be explained with reference to FIGS. 5 to 8.

[0095] The exhaust device may include a fan (40), a filter (50), and a Euro guide (60).

[0096] The fan (40) can suck in contaminated air, which is air on the upper side of the top plate (10), through the opening (12).

[0097] At least a portion of the fan (40) can be placed in the component placement space (S), and in particular, can be placed on the side of the component placement space (S) based on the opening (12) of the top plate (10).

[0098] Between the opening (12) and the fan (40), a passage (d1, d2, d3) for air flow may be provided.

[0099] Air introduced into the component placement space (S) through the opening (12) can flow into the fan (40) through the passages (d1, d2, d3). For example, the space between the opening (12) and the intake port (42) of the fan (40) is connected by the passages (d1, d2, d3), and external contaminated air of the cooking appliance (1) can flow into the passages (d1, d2, d3) through the opening (12) and then flow into the fan (40).

[0100] The filter (50) can be placed in the component placement space (S). In particular, the filter (50) can be placed between the opening (12) and the fan (40). According to the present embodiment, at least a portion of the filter (50) can be placed in the flow paths (d1, d2, d3).

[0101] The filter (50) can filter contaminated air introduced through the opening (12). That is, contaminated air introduced through the opening (12) can pass through the filter (50), be filtered, and then flow toward the fan (40).

[0102] The Euro guide (60) can be placed in the component placement space (S), can accommodate the filter (50) in the internal space, and can provide space to accommodate at least a part of the fan (40) from the outside.

[0103] A flow path (d1, d2, d3) may be formed inside the flow path guide (60). External contaminated air of the cooking appliance (1) may be introduced into the interior of the flow path guide (60) through the opening (12) and may flow to the fan (40) through the flow paths (d1, d2, d3) formed inside the flow path guide (60).

[0104] Below, each component of the exhaust system is explained in more detail.

[0105]

[0106] [Pan]

[0107] FIG. 9 is an exploded perspective view of a fan (40) included in the exhaust device of FIG. 5 to 8.

[0108] Referring to FIGS. 5 through 9, at least a portion of the fan (40) can be accommodated in the Euro guide (60).

[0109] The fan (40) can have at least a portion placed in the component placement space (S) and can draw in air through the opening (12).

[0110] The fan (40) may include an impeller (41), a fan motor (43), a fan housing (45), and a fan cover (47). The impeller (41), the fan motor (43), the fan housing (45), and the fan cover (47) may be assembled so as to be detachable.

[0111] The impeller (41) can rotate around a vertical axis, that is, an up-and-down axis. A space that opens downward can be formed inside the impeller (41), and air sucked in by the impeller (41) can flow into said space.

[0112] The impeller (41) can be connected to the rotation axis of the fan motor (43). The rotation axis of the fan motor (43) can rotate around a vertical axis, and the impeller (41) can rotate around the vertical axis in accordance with the rotation of the rotation axis of the fan motor (43). For example, the fan (40) may be in the form of a centrifugal fan or a scroll fan.

[0113] The fan housing (45) can form the overall exterior of the fan (40). The fan housing (45) may have an internal space for accommodating an impeller (41) and a fan motor (43). The internal space may have a curvature corresponding to the outer surface of the impeller (41), and, for example, may have an overall circular, elliptical, or similar closed curve shape. The inner surface of the fan housing (45) may be formed as a curved surface that surrounds the outer surface of the impeller (41).

[0114] An intake port (42) may be provided on the inner side of the lower surface of the fan housing (45). The intake port (42) may provide a passage necessary for external air of the fan (40) to be sucked into the interior of the impeller (41).

[0115] The intake port (42) may be formed on the side facing the placement position of the top plate (10). As an example, the intake port (42) may be formed at the bottom of the fan (40) to open the internal space of the fan (40) downward.

[0116] An exhaust port (44) may be provided in the fan housing (45). The exhaust port (44) may provide a passage necessary for air sucked into the internal space of the fan housing (45) to be discharged to the outside of the fan (40).

[0117] The exhaust port (44) can be formed to penetrate the fan housing (45) in a horizontal direction. Accordingly, air sucked in vertically through the intake port (42) can be discharged horizontally through the exhaust port (44).

[0118] For example, the exhaust port (44) may be positioned at the rear of the fan housing (45). In this case, air sucked in by the fan (40) may be discharged to the rear, and accordingly, air may be discharged through the rear of the cooking appliance (1). However, the present invention is not limited thereto, and the exhaust port (44) may be positioned at the side of the fan housing (45).

[0119] The fan cover (47) can be detachably coupled to the upper part of the fan housing (45). The fan cover (47) can cover the upper part of the fan housing (45) from the upper side. The fan cover (47) can be coupled to the upper part of the fan motor (43) and the upper part of the fan housing (45) to support the fan motor (43) in the fan housing (45).

[0120] In summary, the fan (40) can draw in air that has flowed into the component placement space (S) through the opening (12) of the top plate (10). At this time, air from the lower side of the fan (40) can be drawn into the fan (40) through the intake port (42) that is open downward. The fan (40) that has drawn in air through the intake port (42) can discharge the drawn-in air through the exhaust port (44). At this time, the exhaust port (44) can be formed in a direction different from the direction in which the intake port (42) opens the interior of the fan (40).

[0121]

[0122] [filter]

[0123] FIG. 10 is an exploded perspective view of a filter (50) included in the exhaust device of FIG. 5 to FIG. 8.

[0124] Referring to FIGS. 5 to 8 and FIG. 10, the filter (50) can be accommodated in the internal space of the flow guide (60), and at least a portion of the filter (50) can be placed in the flow paths (d1, d2, d3) formed in the internal space of the flow guide (60). In particular, the filter (50) can be placed between the opening (12) and the fan (40).

[0125] The filter (50) can perform the function of purifying the air sucked in through the opening (12) of the top plate (10).

[0126] The filter (50) may include first and second filters (51, 52, 53).

[0127] The first filter (51) can be installed in the area where contaminated air sucked in through the opening (12) of the top plate (10) first passes inside the exhaust device.

[0128] The first filter (51) can primarily purify contaminated air containing grease. According to the present embodiment, the first filter (51) may be a grease filter.

[0129] The first filter (51) can be formed with a porous structure. Thus, the first filter (50) can be formed with a structure that effectively captures oil or large particles of contaminants without obstructing the flow of air.

[0130] The opening (12) can be formed in a circular shape in the central region of the top plate (10), and accordingly, the first filter (51) may have a circular cross-section and be in the shape of a cylinder with an open top surface.

[0131] The upper surface of the first filter (51) may be opened upward toward the opening (12), and a space may be formed inside the first filter (51) to temporarily retain contaminated air. Contaminated air sucked into the opening (12) and flowing vertically, i.e. downward, toward the interior of the first filter (51) may temporarily retain inside the first filter (51) and then diffuse radially while passing through the first filter (51) in the horizontal direction.

[0132] Contaminated air introduced into the interior of the first filter (51) may come into contact with the wall surface of the first filter (51) while temporarily staying inside the first filter (51). Accordingly, oil or large particles of contaminants in the contaminated air may adhere to or stick to the wall surface of the first filter (51) and be separated from the contaminated air. Afterward, the air from which contaminants have been removed may pass through the first filter (51) and flow to the second filter (52, 53).

[0133] A plurality of second filters (52, 53) may be provided between the first filter (51) and the fan (40). That is, a plurality of second filters (52, 53) may be placed between the first filter (51) and the intake port (42) of the fan (40).

[0134] A plurality of second filters (52, 53) can be arranged in a manner that wraps around a part of the outer surface of the first filter (51), and can be arranged in a cylindrical shape overall.

[0135] A plurality of second filters (52, 53) can secondarily purify contaminated air that has passed through the first filter (51), that is, air from which contaminants have been removed. In other words, the plurality of second filters (52, 53) can remove gaseous contaminants, such as odor components and volatile organic compounds (VOCs), from the contaminated air that has been primarily purified in the first filter (51). According to the present embodiment, the second filters (52, 53) may be charcoal filters or activated carbon filters. By using a plurality of second filters (52, 53), the cleanliness of the air finally discharged to the outside of the exhaust device can be improved.

[0136] According to the present embodiment, a plurality of second filters (52, 53) may include a second-1 filter (52) and a second-2 filter (53). Based on the placement position of the first filter (51), the second-1 filter (52) and the second-2 filter (53) may be arranged to face each other.

[0137] The second-1 filter (52) may be arranged to wrap around a portion of the front outer surface of the first filter (51) and may be referred to as the second filter on one side. The second-2 filter (53) may be arranged to wrap around a portion of the rear outer surface of the first filter (51) and may be referred to as the second filter on the other side.

[0138] Since the first filter (51) has a cylindrical shape, the second-1 and second-2 filters (52, 53) can be arranged in the shape of an annular segment when viewed in a plane.

[0139] The inner arc surfaces (521, 531) of each of the 2-1 and 2-2 filters (52, 53) may be arranged coaxially with respect to the center of the 1 filter (51) and may be arranged to face the outer circumference of the 1 filter (51) with a preset gap. The outer arc surfaces (522, 532) of each of the 2-1 and 2-2 filters (52, 53) may also be arranged coaxially with respect to the center of the 1 filter (51). That is, the inner arc surfaces (521, 531) and the outer arc surfaces (522, 532) may be arranged to form concentric arcs. The curvature of each of the inner arc surfaces (521, 531) and the outer arc surfaces (522, 532) may be formed to correspond to the curvature of the outer circumference of the 1 filter (51).

[0140] Each of the two sides (523, 524, 533, 534) of the 2-1 and 2-2 filters (52, 53) may be a boundary surface cut along the circumferential direction with respect to the central axis of the 1 filter (51), and may have the shape of a flat surface connecting an inner arc surface (521, 531) and an outer arc surface (522, 532). Both sides (523, 524, 533, 534) may include one side (523, 533) supported in the vertical direction by the filter support member (64), and the other side (524, 534) positioned to be in contact with the inner circumferential surface of the guide housing (61).

[0141] A plurality of second filters (52, 53) can be supported by a filter mounting portion (622, 623, 624, 625) formed on the guide base (62) of the Euro guide (60) and a filter support portion (64) positioned on the upper side of the guide base (62). Here, the lower side of the plurality of second filters (52, 53) can be supported in the vertical direction by the filter mounting portion (622, 623, 624, 625), and one side (523, 533) of the plurality of second filters (52, 53) can be supported in the horizontal direction by the filter support portion (64).

[0142] In summary, the first and second filters (51, 52, 53) can be sequentially arranged at positions spaced apart from each other on the airflow path (d1, d2, d3). Additionally, depending on the arrangement structure of the first and second filters (51, 52, 53), contaminated air can pass through the first filter (51) first and then through the second filter (52, 53). Accordingly, the overall efficiency of contaminant removal can be improved.

[0143] In particular, a first filter (51) and a plurality of second filters (52, 53) are sequentially arranged on the upstream side of the intake port (42) of the fan (40) so that a multi-stage purification process can be performed before contaminated air reaches the fan (40). Accordingly, the cleanliness of the air flowing into the interior of the fan (40) can be increased, and contaminants can be prevented from directly adhering to the impeller (41) of the fan (40). In addition, the efficiency of collecting contaminants can be effectively improved without increasing the intake flow rate of the fan (40), and noise generated from the fan (40) can be suppressed.

[0144] In addition, the first filter (51) is provided in a cylindrical shape, and a plurality of second filters (52, 53) are formed in an annular segment shape, so that air can be diffused radially inside the first filter (51) and then dispersed and introduced through the plurality of second filters (52, 53) to the fan (40). Accordingly, the airflow becomes smooth and the collection efficiency can be uniformly secured.

[0146] [Euro Guide]

[0147] FIG. 11 is an exploded perspective view of a flow guide (60) included in the exhaust device of FIG. 5 to 8. FIG. 12 is a drawing showing the specific configuration of a filter support (64) among the flow guide (60) of FIG. 11.

[0148] Referring to FIGS. 5 to 8 and FIGS. 11 and 12, the Euro guide (60) can be placed in a component placement space (S), and a flow path (d1, d2, d3) can be formed to transmit air sucked in through the opening (12) of the top plate (10) to the fan (40). Additionally, the Euro guide (60) can accommodate the fan (40) from the outside and accommodate the filter (50) in the internal space.

[0149] The Euro guide (60) may include a guide housing (61), a guide base (62), a sealing part (63), a filter support part (64), and a filter fastening part (65).

[0150] The guide housing (61) and the guide base (62) can be joined together to form the exterior of the Euro guide (60). Depending on the joining of the guide housing (61) and the guide base (62), the interior space of the Euro guide (60) can be formed, and the Euro (d1, d2, d3) connecting the opening (12) of the top plate (10) and the fan (40) can be formed in the interior space of the Euro guide (60).

[0151] The guide housing (61) may include a housing body (611), a protrusion (612), and a fan receiving portion (613).

[0152] The housing body (611) can form the overall appearance of the Euro guide (60) and can be combined with the guide base (62) to define the internal space of the Euro guide (60). The lower part of the housing body (611) can be open.

[0153] The protrusion (612) may be extended and formed to protrude in a circular shape from the upper surface of one side of the housing body (611). Here, one side of the housing body (611) may correspond to the lower side of the opening (12).

[0154] A circular opening may be provided on the inner side of the protrusion (612). A cylindrical first filter (51) may be received into the internal space of the flow guide (60) through the opening of the protrusion (612). The protrusion (612) may secure the first filter (51) and may serve as a guide to guide the position of the first filter (51) when the first filter (51) is assembled and disassembled.

[0155] Meanwhile, a sealing portion (63) may be provided in partial contact with the inner surface of the protrusion (612). A portion of the outer surface of the sealing portion (63) may be positioned to be in close contact with the inner surface of the protrusion (612), and the remaining portion of the outer surface of the sealing portion (63) may be positioned to protrude upward from the protrusion (612). When the first filter (51) is received into the internal space of the flow guide (60), at least a portion of the inner surface of the sealing portion (63) may be positioned to be in close contact with the outer surface of the first filter (51).

[0156] The sealing portion (63) can block the gap between the outer surface of the first filter (51) and the inner surface of the protrusion (612), thereby preventing contaminated air sucked into the opening (12) from flowing into the gap. With the sealing portion (63) provided, contaminated air can only flow into the first filter (51). That is, contaminated air can only flow into the inflow path formed in the vertical direction. In addition, the sealing portion (63) can perform the function of stably supporting and fixing the first filter (51) together with the protrusion (612).

[0157] The fan receiving portion (613) may be formed by being recessed on the other side of the housing body (611) and may have an overall circular or cylindrical shape. The fan receiving portion (613) may provide a space for seating the fan (40) from the outside. However, the present invention is not limited thereto, and the fan receiving portion (613) may also provide a space for seating the fan (40) inside the flow guide (60).

[0158] The fan receiving portion (613) may include a lower portion (6131), an inner wall portion (6132), and a support portion (6134).

[0159] The lower portion (6131) may be provided on the lower side of the fan receiving portion (613) so that the fan (40) is stably supported. The lower portion (6131) may have an overall circular shape, and an opening may be formed on the inner side of the lower portion (6131). That is, the lower portion (6131) may have an annular shape or a ring shape.

[0160] An intake port (42) of a fan (40) can be seated on the upper part of the opening of the lower portion (6131). Accordingly, the opening of the lower portion (6131) and the intake port (42) can be connected to each other, and the intake port (42) can be opened downward, that is, in the vertical direction, through the opening.

[0161] The inner wall portion (6132) may be formed by extending along the outer circumference of the lower portion (6131). The inner wall portion (6132) may be formed in the shape of a roughly cylindrical wall protruding upward from the lower portion (6131). The inner wall portion (6132) may be provided in a shape that surrounds the fan (40) from the outer side in the horizontal direction to the vertical direction.

[0162] The support member (6133) can support the fan (40) from below. The support member (6133) can support the intake port (42) so that it is not in direct contact with the guide base (62), which is the lower surface of the flow guide (60), but is spaced apart by a preset distance. By securing the above distance, a sufficient cross-sectional area of ​​the flow path can be secured, and the fan (40) can draw in air flowing through the connecting flow paths (d2, d3) in the vertical direction through the intake port (43). Accordingly, the resistance to air intake is reduced, and air can be drawn in smoothly.

[0163] As the lower portion (6131) and the inner wall portion (6132) are formed, a fan receiving space (6134) may be formed in the fan receiving portion (613), and at least a portion of the fan (40) may be seated in the fan receiving space (6134). When the fan (40) is seated in the fan receiving space (6134), at least a portion of the lower portion of the fan (40) may come into contact with the lower portion (6131) at the lower side of the lower portion (6131), and at least a portion of the front, back, and side of the fan (40) may come into contact with the inner wall portion (6132).

[0164] By the bottom portion (6131) and the inner wall portion (6132) supporting the outer circumference of the fan (40), the fan (40) can be stably positioned so that it does not shake up, down, left, or right. Additionally, at least a portion of the fan receiving space (6133) can be opened to the rear, and the exhaust port (44) of the fan (40) can be exposed to the outside through the opened fan receiving space (6133).

[0165] According to the present embodiment, the bottom of the fan receiving portion (613) may be positioned between the intake port (42) and the top plate (10). Additionally, a flow path (d1, d2, d3) may be formed between the bottom of the fan receiving portion (613) and the top plate (10), and air passing through the flow path (d1, d2, d3) may pass through the bottom of the fan receiving portion (613) and the intake port (42) and be sucked into the fan (40).

[0166] The guide base (62) can cover the open lower surface of the guide housing (61). That is, the guide base (62) can correspond to the lower surface of the Euro guide (60). The guide housing (61) and the guide base (62) are combined to form an internal space of the Euro guide (60) in which the Euros (d1, d2, d3) are formed.

[0167] The guide base (62) may include a guide base body (621) and filter mounting portions (622, 623, 624, 625).

[0168] The guide base body (621) may be a plate forming the overall shape of the guide base (62) and may provide structural rigidity to the guide base (62).

[0169] A filter mounting portion (622, 623, 624, 625) for mounting a second filter (52, 53) may be formed on one side of the guide base body (621). The filter mounting portion (622, 623, 624, 625) may be formed to protrude upward from the guide base body (621) and may have a predetermined height. Accordingly, the filter mounting portion (622, 623, 624, 625) can stably support the second filter (52, 53) without shaking.

[0170] The filter mounting portions (622, 623, 624, 625) may be formed to correspond to each of the plurality of second filters (52, 53). The filter mounting portions (622, 623, 624, 625) may include a first filter mounting portion (622, 624) for mounting the inner arc surface (521, 531) of the second-1 and second-1 filters (52, 53), and a second filter mounting portion (623, 625) for mounting the outer arc surface (522, 532) of the second-1 and second-1 filters (52, 53). The first filter mounting portion (622, 624) and the second filter mounting portion (623, 625) may be formed as annular segments with a concentric arc shape based on the center of the first filter (51).

[0171] In particular, the second filter mounting portion (623, 625) can be positioned to be in contact with the inner surface of the guide housing (61). Accordingly, the other side (524) of the second-1 filter (52) can be positioned to be in contact with the first part of the inner surface of the guide housing (61), and the other side (534) of the second-2 filter (53) can be positioned to be in contact with the second part of the inner surface of the guide housing (61).

[0172] FIG. 8 illustrates a state in which the second filter (52, 53) is stably seated and fixed to the guide base (62) by the filter seating portions (622, 623, 624, 625).

[0173] The filter support member (64) is positioned on the upper side of the guide base (62) between the first filter (51) and the fan (40) and can support a plurality of second filters (52, 53) in the vertical direction inside the Euro guide (60). Together with the filter seating members (622, 623, 624, 625), the filter support member (64) can stably support the second filters (52, 53) without shaking.

[0174] The outer region of the first filter (51) may be composed of a first outer region in which the second-1 and second-2 filters (52, 53) surround the outer surface of the first filter (51), and a second outer region (a1, a2, see FIG. 13) other than the first outer region. The second outer region may include a part (a1) and another part (a2) of the second outer region.

[0175] A portion (a1) of the second outer region may be formed adjacent to and facing the fan (40). A filter support (64) may be placed in a portion (a1) of the second outer region.

[0176] Another part (a2) of the second outer region may be formed far away from the fan (40) without facing it. The other part (a2) of the second outer region may be formed by a portion of the inner surface of a flow guide (60) that continuously connects the first and second parts of the other side (524, 534) of each of the second-1 and second-2 filters (52, 53), the outer surface of the first filter (51), and the inner surface of the guide housing (61). As described above, the first part is the contact portion between the other side (524) of the second-1 filter (52) and the inner surface of the guide housing (61), and the second part is the contact portion between the other side (534) of the second-2 filter (53) and the inner surface of the guide housing (61).

[0177] The filter support (64) may include a first opposing surface (641), a second opposing surface (642), a third opposing surface (643), and a fourth opposing surface (644).

[0178] The first opposing surface (641) may be a surface facing the first filter (51). The first opposing surface (641) may have an arc shape or an annular segment shape based on the center of the first filter (51). The curvature of the first opposing surface (641) may be formed to correspond to the curvature of the outer surface of the first filter (51).

[0179] The second opposing surface (642) may be a surface facing the fan (40). The second opposing surface (642) may have an arc shape or an annular segment shape based on the center of the internal space of the fan (40) in which the impeller (41) is accommodated. The curvature of the second opposing surface (642) may be formed to correspond to the curvature of the inner circumference of the fan housing (45) constituting the internal space of the fan (40).

[0180] The third opposing surface (643) may be a surface facing one side surface (523) of the second-1 filter (52), and the fourth opposing surface (644) may be a surface facing one side surface (533) of the second-2 filter (53). Since one side surface (523, 533) of the second-1 and second-2 filters (52, 53) is formed flat, the third and fourth opposing surfaces (643, 644) may also be formed flat. Through the third and fourth opposing surfaces (643, 644), one side surface (523, 533) of the second filter (52, 53) may be supported in the vertical direction.

[0181] A pair of support ribs (6431, 6441) may be formed protrudingly on each of the third and fourth opposing surfaces (643, 644). The pair of support ribs (6431, 6441) may be arranged to face each other at both ends of the third and fourth opposing surfaces (643, 644). One side (523, 533) of the second filter (52, 53) may be supported through the pair of support ribs (6431, 6441), thereby allowing the second filter (52, 53) to be stably supported without shaking.

[0182] Meanwhile, the virtual line extending from the third opposing surface (643) and the virtual line extending from the fourth opposing surface (644) may intersect at the center (C) of the first filter (51). At this time, the angle (θ) formed by the two virtual lines may be set to a predetermined value.

[0183] The filter fastening portion (65) may be a member for fastening the second filter (52, 53) on the Euro guide (60). The filter fastening portion (65) may be formed in an annular segment shape or a ring shape, and a part of the filter fastening portion (65) may be detachably coupled to the upper surface of the filter support portion (64) through a fastening means such as a bolt. The coupled filter fastening portion (65) may be fixed by pressing the upper surface of the second filter (52, 53).

[0184] The filter connection part (65) can be easily separated when replacing the second filter (52, 53) and can stably fix the second filter (52, 53) in cooperation with the support ribs (6431, 6441) of the third and fourth opposing surfaces (643, 644).

[0185] Meanwhile, the protrusion (612), filter seating portion (622, 623, 624, 625), filter support portion (64) and filter fastening portion (65) may form a filter receiving portion for receiving the filter (50).

[0186] Both the first and second filters (51, 52, 53) can be inserted into the interior of the Euro guide (60) through the opening (12). The assembly of the first and second filters (51, 52, 53) can be performed as follows.

[0187] First, the second filter (52, 53) moves downward through the opening (12), and then the lower surface of the second filter (52, 53) can be seated on the filter mounting portion (622, 623, 624, 625). Accordingly, the second filter (52, 53) can be primarily fixed.

[0188] Next, the filter support member (64) can be moved and positioned between the second-1 filter (52) and the second-2 filter (53). One side (523, 533) of the second-1 and second-2 filters (52, 53) can be inserted into a pair of support ribs (6431, 6441) formed on the third and fourth opposing surfaces (643, 644) of the filter support member (64). Accordingly, the second filters (52, 53) can be secondarily fixed.

[0189] Additionally, the filter fastening portion (65) can be coupled to the filter support portion (64). The coupled filter fastening portion (65) can press the upper surface of the second filter (52, 53). Accordingly, the second filter (52, 53) can be secondarily fixed.

[0190] Afterwards, the Euro guide (60) passes through the protrusion (612) and the first filter (51) can be received and positioned between the second-1 filter (52) and the second-2 filter (53).

[0191] Finally, a sealing portion (63) can be inserted between the inner surface of the protrusion (612) and the upper outer surface of the first filter (51).

[0192]

[0193] [Euro and Fluid Flow]

[0194] FIGS. 13 to 15 are cross-sectional views showing fluid flow inside an exhaust device, where FIG. 13 is a planar cross-sectional view, FIG. 14 is a frontal cross-sectional view, and FIG. 15 is a right-side cross-sectional view.

[0195] Referring to FIGS. 5 to 15, a flow path (d1, d2, d3) for guiding the flow of air can be formed inside the flow path guide (60).

[0196] Euros (d1, d2, d3) may include an inflow Euro (d1) and a connecting Euro (d2, d3).

[0197] The inlet channel (d1) can be defined as a vertical channel through which air introduced from the opening (12) of the top plate (10) flows into the first filter (51).

[0198] The inlet passage (d1) is connected to the opening (12), and external contaminated air of the cooking appliance (1) can be introduced into the inlet passage (d1) through the opening (12). A first filter (51) may be placed on the inlet passage (d1). That is, the inlet passage (d1) may be formed vertically inside the first filter (51).

[0199] The connecting path (d2, d3) can be defined as a horizontal path through which air introduced into the first filter (51) passes through the second filter (52, 53) and flows to the intake port (42) of the fan (40).

[0200] The connecting passage (d2, d3) connects the inlet passage (d1) and the intake port (42) and functions as a passage to transfer air flowing from the inlet passage (d1) to the fan (40). Air flowing through the inlet passage (d1) can be introduced into the second filter (52, 53) after passing through the first filter (51), and air passing through the second filter (52, 53) can be transferred to the intake port (42). The first and second filters (51, 52, 53) can be placed on the connecting passage (d2, d3), and in particular, the second filter (52, 53) can be placed.

[0201] The connecting channels (d2, d3) can be branched into multiple channels. The branched connecting channels (d2, d3) can transmit air flowing vertically through the inlet channel (d1) to the horizontal direction. The fan (40) can discharge air sucked in vertically through the intake port (42) to the horizontal direction.

[0202] In this embodiment, the connecting channels (d2, d3) may be branched into a first connecting channel (d2) and a second connecting channel (d3). A second-1 filter (52) may be placed in the first connecting channel (d2), and a second-2 filter (53) may be placed in the second connecting channel (d3).

[0203] The first connecting channel (d2) may be a channel for air discharged from the front outer surface of the first filter (51) to flow through the second-1 filter (52) to the intake port (42) of the fan (40). The first connecting channel (d2) may be formed based on the front outer surface of the first filter (51), the second-1 filter (52), and the front inner surface of the channel guide (60).

[0204] The second connecting channel (d3) may be a channel for air to be discharged to the rear outer surface of the first filter (51) to pass through the second-2 filter (53) and flow to the intake port (42) of the fan (40). The second connecting channel (d3) may be formed based on the rear outer surface of the first filter (51), the second-2 filter (53), and the rear inner surface of the channel guide (60).

[0205] The air flow is described below.

[0206] Contaminated air introduced from outside the cooking device (1) flows into the vertical inlet path (d1) through the opening (12) of the top plate (10) and is temporarily retained inside the first filter receiving section (61). Afterwards, the retained air passes through the first filter (51), diffuses radially, and then flows into the first connecting path (d2) and the second connecting path (d3) branched horizontally, passing through the second-1 filter (52) and the second-2 filter (53). Accordingly, the contaminated air is filtered through the first filter (51) and the second filters (52, 53). The filtered air flows further through the connecting paths (d2, d3), is sucked into the intake port (42) formed on the lower side of the fan (40), and then discharged. In this way, the connecting paths (d2, d3) can provide an independent flow path that guides only the purified air that has passed through the filter (50) to the fan.

[0207] According to the present embodiment, air introduced through the opening (12) of the top plate (10) can be delivered to the fan (40) through a plurality of branched connecting passages (d2, d3). Accordingly, the effective cross-sectional area required for the fan (40) to suck in air can be increased, and the air supply to the fan (40) can be evenly distributed. Consequently, the suction performance of the fan (40) can be improved.

[0208] In addition, according to the present embodiment, the first filter (51) and the second filter (52, 53) are sequentially arranged on the upstream side of the intake port (42) of the fan (40), so that contaminated air can undergo a multi-stage purification process before entering the fan (40). Accordingly, the cleanliness of the air entering the interior of the fan (40) is increased, and contaminants can be prevented from directly adhering to the impeller (41) of the fan (40). Furthermore, the efficiency of collecting contaminants can be effectively improved without increasing the intake flow rate of the fan (40), and noise can be suppressed.

[0209] In addition, according to the present embodiment, the first filter (51) is provided in a cylindrical shape, and a plurality of second filters (52, 53) arranged in branched connecting channels (d2, d3) may be formed in an annular segment shape. Accordingly, air is diffused radially inside the first filter (51) and then dispersed into the plurality of second filters (52, 53), thereby facilitating the flow of air and ensuring uniform collection efficiency.

[0210] Meanwhile, a part (a1) of the second outer region of the first filter (51) is provided with a filter support (64), and the filter support (64) is positioned in close proximity to one side (523, 533) of the second filter (52, 53) and faces the first filter (51) and the fan (40). Accordingly, a part (a1) of the second outer region is closed by the filter support (64) and is an area where air cannot pass through. At this time, in order to form a part (a1) of the second outer region as an area where air cannot pass through, the angle (θ) between a virtual straight line extending from the third opposing surface (643) and a virtual straight line extending from the fourth opposing surface (644) can be formed as any one value between 37° and 67°.

[0211] Additionally, another part (a2) of the second outer region of the first filter (51) is defined as a part of the inner surface of the flow guide (60) that continuously connects the other side (524, 534) of each of the second-1 and second-2 filters (52, 53), the outer surface of the first filter (51), and the first and second parts of the inner surface of the guide housing (61). Accordingly, the other part (a2) of the second outer region is also an area through which air cannot pass.

[0212] Based on the above description, according to the present embodiment, contaminated air can be prevented from leaking into the gap inside the flow guide (60) by the above-described part (a1) and other part (a2) of the second outer region, and contaminated air can flow only through the connecting flow path (d2, 23). That is, air introduced into the first filter (51) through the inlet flow path (d1) flows only through the connecting flow path (d2, d3) where the second filter (52, 53) is placed, and the air flowing through the inlet flow path (d1) is not delivered to the fan (40) in the area where the second filter (52, 53) is not placed. Accordingly, the air flow must pass through the second filter (d2, d3), thereby improving purification efficiency.
