The housing intake port (123) may be positioned on the upper side (e.g., +Z-axis direction) of the fan (110). The housing intake port (123) may serve to introduce air from the upper intake port (20) of the cooktop (10) into the fan housing (120).
[0093] According to one embodiment, the outer surface forming the housing intake port (123) may be formed as a curved surface overall. However, it is not limited thereto, and some parts of the outer surface forming the housing intake port (123) may be formed as a flat surface (e.g., see FIG. 10a).
[0094] According to one embodiment, the circumference of the housing intake port (123) may include a first portion (1231) and a second portion (1232). The circumference of the housing intake port (123) may be divided into a first portion (1231) and a second portion (1232). The second portion (1232) may be located further from the upper intake port (20) of the cooktop (10) than the first portion (1231). The first portion (1231) may have, for example, a roughly semicircular shape. The second portion (1232) may have, for example, a roughly semicircular shape.
[0095] According to one embodiment, the first part (1231) and the second part (1232) may have radii of different sizes. The radius of the second part (1232) may be larger than the radius of the first part (1231). The perimeter (or circumference) of the second part (1232) may be longer than the perimeter (or circumference) of the first part (1231). Due to the difference between the first part (1231) and the second part (1232), the area of the housing intake port (123) formed corresponding to the second part (1232) may be larger than the area of the housing intake port (123) formed corresponding to the first part (1231).
[0096] By forming the circumference of the second part (1232) to be longer than the circumference of the first part (1231), air can pass through the upper intake port (20) uniformly, even though air flowing through a bypass path is formed among the air entering from the upper intake port (20) as described later in FIGS. 7 and 8.
[0097] According to one embodiment, the housing intake port (123) may have an asymmetrical shape with respect to a vertical axis (e.g., Z-axis) passing through the rotation axis (R) of the fan (110). The housing intake port (123) may have an asymmetrical structure due to a difference in shape and / or size between the first part (1231) and the second part (1232).
[0098] According to one embodiment, the first distance (620), which is the maximum distance between the rotation axis (R) of the fan (110) and the first part (1231), may be smaller than the second distance (630), which is the maximum distance between the rotation axis (R) of the fan (110) and the second part (1232).
[0099] The point furthest from the rotation axis (R) of the fan (110) in the first part (1231) may be referred to as the first point (1231a). The point furthest from the rotation axis (R) of the fan (110) in the second part (1232) may be referred to as the second point (1232a). For example, the first distance (620) may refer to the horizontal distance between the rotation axis (R) of the fan (110) and the first point (1231a). For example, the second distance (630) may refer to the horizontal distance between the rotation axis (R) of the fan (110) and the second point (1232a). Here, the horizontal distance may refer to the distance measured with respect to the X-axis direction.
[0100] According to one embodiment, the value obtained by dividing the radius of the fan (110) by the first distance (620) may be 0.63 to 0.83. For example, the value obtained by dividing the radius of the fan (110) by the first distance (620) may be 0.73.
[0101] According to one embodiment, the value obtained by dividing the radius of the fan (110) by the second distance (630) may be 0.68 to 0.88. For example, the value obtained by dividing the radius of the fan (110) by the second distance (630) may be 0.78.
[0102] According to one embodiment, the value obtained by dividing the radius of the fan (110) by the first distance (620) cannot exceed the value obtained by dividing the radius of the fan (110) by the second distance (630).
[0103] According to one embodiment, the rotation axis (R) of the fan (110) and the center point (C) of the housing intake (123) may be positioned so as not to correspond to each other. That is, the rotation axis (R) and the center point (C) may not be aligned with each other. The rotation axis (R) of the fan (110) and the center point (C) of the housing intake (123) may be positioned so as not to overlap vertically. Here, the center point (C) of the housing intake (123) may refer to the center point of the maximum diameter portion of the housing intake (123).
[0104] According to one embodiment, the maximum diameter of the housing intake port (123) may be the sum of the first distance (620) and the second distance (630). Here, the center point (C) of the housing intake port (123) may be a point located at the center with respect to the major axis (610) of the housing intake port (123).
[0105] According to one embodiment, the circumference defining the housing intake port (123) may have a variable curvature as illustrated.
[0106] FIG. 7 is a plan view showing the internal configuration of a cooking appliance according to one embodiment, viewed from above.
[0107] FIG. 8 is a side cross-sectional view of a cooking device according to one embodiment.
[0108] All features, components, and / or arrangement relationships between components illustrated in FIGS. 7 and 8 may be included, either alone or in combination with, the features, components, and arrangement relationships between components described in other figures of this specification. Likewise, all features, components, and / or arrangement relationships between components described in relation to FIGS. 1 through 6 and FIGS. 9 through 10c may be included, either alone or in combination with, the features, components, and arrangement relationships between components described in FIGS. 7 and 8.
[0109] Referring to FIGS. 7 and 8, a cooking appliance (1) according to one embodiment may include a cooktop (10) and a hood (30). FIG. 7 is a schematic drawing in which the top plate (11) and bottom plate (12) of the cooktop (10) are omitted to illustrate the air passage passing through the upper intake port (20).
[0110] According to one embodiment, the housing intake port (123) may be divided into a first region (123a) and a second region (123b) based on a virtual line passing through the center point (C) of the housing intake port (123). The second region (123b) may be located further from the upper intake port (20) than the first region (123a). The first region (123a) may refer to an area facing the upper intake port (20) (e.g., in the -X direction) based on the center point (C). The first region (123a) and the second region (123b) may each have a roughly semicircular shape. Here, the virtual line passing through the center point (C) may be a virtual line parallel to the short side of the cooktop (10). Here, the virtual line passing through the center point (C) may be a virtual line parallel to the long side of the upper intake port (20). Here, the virtual line passing through the center point (C) may be parallel to the Y-axis.
[0111] According to one embodiment, the first region (123a) and the second region (123b) may have different sizes of area. For example, the second region (123b) may have a larger area than the first region (123a). The first region (123a) may be an area through which air directly introduced through the upper intake port (20) passes. The second region (123b) may be an area through which air introduced bypassing through the upper intake port (20) passes.
[0112] According to one embodiment, when viewed from the top (e.g., +Z side) toward the bottom, the size of the blade (113) visible through the first region (123a) may be smaller than the size of the blade (113) visible through the second region.
[0113] According to one embodiment, when the ventilation device (100) is in operation, air introduced through the upper intake port (20) can be introduced into the housing intake port (123) of the ventilation device (100) along the path shown in FIG. 7.
[0114] According to one embodiment, air introduced through the upper intake port (20) may flow into the housing intake port (123) along the first path (F1) or the second path (F2). According to one embodiment, some of the air introduced through the upper intake port (20) may flow into the first region (123a) along the first path (F1). Other parts of the air introduced through the upper intake port (20) may flow into the second region (123b) along the second path (F2).
[0115] According to one embodiment, the second path (F2) may be longer than the first path (F1). The first path (F1) may be referred to as a straight path moving from the upper intake port (20) to the housing intake port (123). The second path (F2) may be referred to as a detour path moving from the upper intake port (20) to the housing intake port (123). In the case of a cooking appliance (1) including a hood (30), due to space constraints, the gap between the housing intake port (123) and the cooktop (10) is narrow, so an airflow may be formed that bypasses the second path (F2) and enters the housing intake port (123). The air flowing through the second path (F2) may pass through the second region (123b) of the housing intake port (123).
[0116] Since the length of the second flow path (F2) is longer than that of the first flow path (F1), the flow rate of air passing through the housing intake port (123) may decrease as it moves further away from the upper intake port (20). Due to the difference between the first flow path (F1) and the second flow path (F2), a difference in flow rate occurs at different locations of the upper intake port (20), which may reduce the efficiency of air flow for ventilation.
[0117] In the present disclosure, the shape of the housing intake port (123) is implemented as an asymmetric shape rather than a circular shape. A second region (123b) relatively far from the upper intake port (20) is formed larger than the first region (123a), thereby expanding the area through which air flowing along the second flow path (F2) can pass through the housing intake port (123). By forming the second region (123b) larger than the first region (123a), the air flowing into the fan (110) can be homogenized.
[0118] According to one embodiment, when viewed from above, the rotation axis (R) of the fan (110) may be positioned closer to the upper intake (20) than to the center point (C) of the housing intake (123).
[0119] According to one embodiment, the first horizontal distance (710), which is the horizontal distance between the rotation axis (R) of the fan (110) and the upper intake port (20), may be smaller than the second horizontal distance (720), which is the horizontal distance between the center point (C) of the housing intake port (123) and the upper intake port (20). The value obtained by dividing the first horizontal distance (710) by the second horizontal distance (720) may be greater than 1 and less than 1.03. Here, the horizontal distance may refer to the distance measured based on the cooking appliance when viewed from above.
[0120] FIG. 9 is an experimental graph to explain the suction efficiency of a ventilation device in a cooking appliance according to one embodiment.
[0121] FIG. 9 is a graph showing the change values of airflow and energy efficiency measured based on the relationship between the radius of the housing intake port (123) of the cooking appliance (1) shown in FIG. 1 to 8 and the radius of the fan (110).
[0122] In FIG. 9, the horizontal axis may represent the value obtained by dividing the radius of the fan (110) by the radius of the housing intake (123) (hereinafter referred to as the radius ratio). The left vertical axis may represent the airflow passing through the housing intake (123). That is, it may represent the intake volume of the housing intake (123). The unit of airflow may be CMH (Cubic Meter per Hour). The right vertical axis may represent energy efficiency. The higher the energy efficiency value, the better the efficiency of the energy used for ventilation.
[0123] In FIG. 9, the first line (910) represents an airflow value according to the radius ratio. The second line (920) represents an energy efficiency value according to the radius ratio. The first line (910) and the second line (920) may be experimental data assuming that the housing intake port (123) is in the shape of a circle.
[0124] Referring to FIG. 9, as the radius ratio increases, the amount of air passing through the housing intake port (123) in the cooking device (1) according to one embodiment may increase. For example, as the radius of the housing intake port (123) increases, the amount of air passing through the housing intake port (123) may increase.
[0125] When the housing intake port (123) has a circular shape, the energy efficiency of the cooking appliance (1) may not be proportional to the radius ratio. As shown in FIG. 9, energy efficiency increases as the radius ratio increases from 0.69 to 0.73, but when the radius ratio exceeds 0.73, the energy efficiency may be inversely proportional to the radius ratio. When the housing intake port (123) of the ventilation device (100) has a circular shape, the airflow and energy efficiency can be optimized when the radius ratio is 0.73.
[0126] A cooking device (1) according to one embodiment can improve airflow and energy efficiency compared to a circular housing intake port (123) by forming an asymmetrical housing intake port (123). It can be experimentally confirmed that when an asymmetrical housing intake port (123) is configured, it has a first airflow (930) and a first energy efficiency (940).
[0127] It can be confirmed through the experimental graph of FIG. 9 that the first airflow (930) and first energy efficiency (940) measured in the cooking device (1) according to one embodiment are improved compared to the airflow and energy efficiency when the radius ratio is 0.73 in the circular housing intake port (123). Here, the shape of the housing intake port (123) and the arrangement relationship between the housing intake port (123) and the fan (110) are omitted as described above in FIG. 1 to 8.
[0128] FIGS. 10a, FIGS. 10b, and FIGS. 10c are drawings for explaining the shapes of housing intake ports of cooking appliances according to various embodiments.
[0129] All features, components, and / or arrangement relationships between components illustrated in FIGS. 10a, 10b, and 10c may be included, either alone or in combination with, the features, components, and arrangement relationships between components described in other figures of this specification. Likewise, all features, components, and / or arrangement relationships between components described in relation to FIGS. 1 through 9 may be included, either alone or in combination with, the features, components, and arrangement relationships between components described in FIGS. 10a, 10b, and 10c.
[0130] FIGS. 10a, 10b, and 10c are drawings illustrating exemplary shapes of housing intake ports (123-1, 123-2, 123-3) for optimizing the airflow drawn into a ventilation device (e.g., ventilation device (100) of FIG. 3) and the energy efficiency of a cooking appliance (e.g., cooking appliance (1) of FIG. 2). The shapes shown in FIGS. 10a, 10b, and 10c are exemplary and do not limit the scope of the present disclosure.
[0131] FIGS. 10a, FIGS. 10b, and FIGS. 10c schematically illustrate the shape of the housing intake port (123-1, 123-2, 123-3), the center point (C-1, C-2, C-3) of the housing intake port (123-1, 123-2, 123-3), and the rotation axis (R) of the fan (e.g., the fan (110) of FIG. 5) based on a view from above. The illustrated configurations may represent the shape of the housing intake port (123-1, 123-2, 123-3) of the ventilation device (100) of FIGS. 1 to 8.
[0132] Referring to FIG. 10a, FIG. 10b and FIG. 10c, in a cooking device (1) according to one embodiment, the center points (C-1, C-2, C-3) of the housing intake ports (123-1, 123-2, 123-3) may not correspond to the rotation axis (R) of the fan (110). For example, the center points (C-1, C-2, C-3) of the housing intake ports (123-1, 123-2, 123-3) and the rotation axis (R) of the fan (110) may not overlap vertically. The center points (C-1, C-2, C-3) of the housing intake ports (123-1, 123-2, 123-3) may be located further away from the upper intake port (e.g., upper intake port (20) of FIG. 3) of the cooktop (e.g., cooktop (10) of FIG. 3) than the rotation axis (R) of the fan (110).
[0133] According to one embodiment, the housing intake port (123-1, 123-2, 123-3) may be formed such that the intake area horizontally far from the upper intake port (20) with respect to the rotation axis (R) of the fan (110) is larger than the intake area of the area adjacent to the upper intake port (20).
[0134] Referring to FIG. 10a, the perimeter of a housing intake port (123-1) according to one embodiment (e.g., housing intake port (123) of FIG. 5) may include a first curved surface (1010), a second curved surface (1030), and a connecting surface (1020).
[0135] According to one embodiment, the first curved surface (1010) and the second curved surface (1030) may be formed to face in opposite directions. The first curved surface (1010) may be formed spaced apart from the second curved surface (1030). The first curved surface (1010) may have a semicircular shape, for example. The second curved surface (1030) may have a semicircular shape, for example. The curvature of the first curved surface (1010) and the curvature of the second curved surface (1030) may be substantially the same, but are not limited thereto.
[0136] According to one embodiment, the connecting surface (1020) may be a surface connecting the first curved surface (1010) and the second curved surface (1030). The connecting surface (1020) may be, for example, a flat surface. Although the connecting surface (1020) is depicted larger than its actual size in FIG. 10a for convenience of explanation, this is exemplary and the relative size of the connecting surface (1020) to the first curved surface (1010) or the second curved surface (1030) is not limited to what is depicted.
[0137] Referring to FIG. 10b, the circumference of a housing intake port (123-2) (e.g., housing intake port (123) of FIG. 5) according to one embodiment may include a first curved surface (1040) and a second curved surface (1050).
[0138] According to one embodiment, the first curved surface (1040) and the second curved surface (1050) may be formed to face in opposite directions. The first curved surface (1040) and the second curved surface (1050) may be located to the right (e.g., in the -X direction) and to the left (e.g., in the +X direction), respectively, with respect to the illustrated centerline (D). The first curved surface (1040) and the second curved surface (1050) may be connected to each other. The first curved surface (1040) and the second curved surface (1050) may have different average radii. For example, the average radius of the first curved surface (1040) may be smaller than the average radius of the second curved surface (1050).
[0139] According to one embodiment, the rotation axis (R) of the fan (110) can be positioned so as not to overlap with the center point (C-2) of the housing intake port (123-2).
[0140] Referring to FIG. 10c, the circumference of the housing intake port (123-3) according to one embodiment (e.g., the housing intake port (123) of FIG. 5) may have a circular shape. The circumference of the housing intake port (123-3) may have a circular shape with a constant radius. Although the housing intake port (123-3) has a circular shape, the center point (C-3) of the housing intake port (123-3) is positioned at a horizontal distance from the upper intake port (20) when compared to the rotation axis (R) of the fan (110), thereby improving airflow and energy efficiency as described in FIG. 1 to 9.
