Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and in particular to a smoke guiding device, a range hood module, and a range hood. Background Technology

[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance used to purify the kitchen environment. It can quickly remove the exhaust gas produced by the stove and the oil fumes generated during cooking and exhaust them outdoors to purify the kitchen environment. It is widely used in people's lives and effectively improves people's living environment.

[0003] The suction efficiency of a range hood is its primary performance characteristic, and improving this efficiency to enhance the cooking environment has always been a pursuit of those skilled in the art. To further improve suction, some existing range hoods incorporate openable smoke guides. These guides direct cooking fumes into the suction duct and prevent them from escaping, thus effectively improving the suction performance.

[0004] However, due to some structural defects in the existing smoke guide plates, some oil fumes still flow out along the gap between the smoke guide plate and the range hood's outer casing, thereby weakening the range hood's smoke extraction performance and failing to further improve the cooking environment. This has become a problem that those skilled in the art urgently need to solve. Summary of the Invention

[0005] Therefore, it is necessary to provide a smoke guiding device, a range hood module, and a range hood to address the problem of oil fumes flowing out along the gap between the smoke guide plate and the outer casing of the range hood.

[0006] A smoke guiding device, comprising:

[0007] The outer casing has a smoke inlet for connecting to the outside atmosphere;

[0008] A smoke guide plate, rotatably mounted on the housing, is used to open or close the smoke inlet; and

[0009] The blocking component includes a mounting plate and a smoke-blocking structure. The mounting plate is disposed on the surface of the smoke guide plate facing the smoke inlet. One side of the smoke-blocking structure is connected to the mounting plate, and the other side of the smoke-blocking structure extends in a direction away from the smoke guide plate.

[0010] In one embodiment, the smoke-blocking structure includes a first smoke-blocking plate and a second smoke-blocking plate. The first smoke-blocking plate is disposed on the side of the mounting plate near the connection end between the smoke guide plate and the outer casing, and the second smoke-blocking plate is disposed on the side of the mounting plate away from the connection end between the smoke guide plate and the outer casing.

[0011] In one embodiment, the first smoke baffle extends longitudinally along the first direction, the second smoke baffle extends longitudinally along the first direction, and the first direction is parallel to the extension direction of the rotation axis of the smoke guide plate (123).

[0012] In one embodiment, the first smoke baffle extends downward at an angle from one end connected to the mounting plate to the end away from the mounting plate.

[0013] In one embodiment, the second smoke baffle extends downward at an angle from one end connected to the mounting plate to the end away from the mounting plate.

[0014] In one embodiment, the smoke-blocking structure includes a third smoke-blocking plate and a fourth smoke-blocking plate, the third smoke-blocking plate and the fourth smoke-blocking plate being located on opposite sides of the mounting plate, and the third smoke-blocking plate being connected between one end of the first smoke-blocking plate and one end of the second smoke-blocking plate, and the fourth smoke-blocking plate being connected between the other end of the first smoke-blocking plate and the other end of the second smoke-blocking plate.

[0015] In one embodiment, an adhesive layer is provided between the mounting plate and the smoke guide plate.

[0016] In one embodiment, the mounting plate has a protrusion that protrudes toward the smoke guide plate, the protrusion contacting the smoke guide plate, and the adhesive layer filling the portion of the mounting plate without the protrusion between the mounting plate and the smoke guide plate.

[0017] A smoke hood module includes the aforementioned smoke guiding device.

[0018] A range hood includes the aforementioned range hood module.

[0019] The aforementioned air guide device and smoke-blocking structure obstruct and disrupt the escape route of the oil fumes. The oil fumes cannot escape along the edge of the smoke guide plate due to the obstruction of the smoke-blocking structure. As the obstructed and disrupted oil fumes swirl in the air, they are sucked away by the suction device, thereby improving the smoke extraction effect of the range hood and improving the cooking environment.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0032] See Figure 1 and Figure 2 , Figure 1 This diagram shows the internal structure of the smoke hood module in one embodiment of the present application when the air guide plate is in the open state. Figure 2 This diagram shows the internal structure of the smoke hood module in one embodiment of the present application when the air guide plate is in the closed state.

[0033] One embodiment of this application provides a range hood including an air conditioning module and a range hood module 100 connected to each other. The air conditioning module is used to regulate the indoor temperature to improve the temperature of the kitchen environment, and the range hood module 100 is used to extract the cooking fumes generated during cooking to reduce the concentration of cooking fumes in the kitchen. It is understood that in some other embodiments, the range hood may only include the range hood module 100 without an air conditioning module, and this is not a limitation.

[0034] The range hood module 100 includes a suction device 140 and a smoke guiding device 120. The suction device 140 is installed inside one end of the smoke guiding device 120 to provide power for the flow of oil fumes. Under the action of the suction device 140, oil fumes from the external environment enter the smoke guiding device 120 and are discharged outside the smoke guiding device 120 after filtration.

[0035] The smoke guiding device 120 includes a housing 121, a smoke guiding plate 123, and an oil cup 127. The smoke guiding plate 123 and the oil cup 127 are both installed on the housing 121. The smoke guiding plate 123 is used to prevent the escape of oil fumes, and the oil cup 127 is used to collect the oil stains generated by the smoke machine module 100 during operation.

[0036] Specifically, the outer shell 121 has a hollow shell-like structure, and the length direction of the outer shell 121 is the first direction (i.e., Figure 3 The width direction of the outer shell 121 is the second direction (i.e., the X direction in the middle), and the width direction of the outer shell 121 is the second direction (i.e., the X direction in the middle). Figure 1 The Y direction of the outer shell 121 is the third direction (i.e., the height direction of the outer shell 121 is the third direction). Figure 1 In the Z-direction (as shown in the image), the first direction, the second direction, and the third direction intersect each other pairwise. In a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other pairwise. "Downward" as mentioned below refers to along the Z-direction. Figure 1 It extends in the opposite direction to the direction indicated by the Z-axis.

[0037] Furthermore, a suction duct 121a extending in a third direction is formed inside the outer casing 121. The suction device 140 is installed on the top of one end of the outer casing 121 in the third direction and is connected to one end of the suction duct 121a. The outer casing 121 has a smoke inlet 121b at the other end in the third direction, which is connected to the external atmosphere and the suction duct 121a. The smoke inlet 121b is located on one side of the outer casing 121 in the second direction.

[0038] The smoke guide plate 123 is generally rectangular flat. It is rotatably mounted on the side of the housing 121 where the smoke inlet 121b is located, and is situated on the side of the smoke inlet 121b closest to the suction device 140. The smoke guide plate 123 is used to open or close the smoke inlet 121b. Specifically, the smoke guide plate 123 rotates about a rotation axis extending in a first direction. The smoke guide plate 123 can be rotatably connected to the housing 121 via hinges, spherical joints, or other connection methods; the specific rotatable connection method is not limited here. More specifically, in some embodiments, the smoke guide plate 123 has hinge structures on opposite sides along its length, thereby hinged to the housing 121.

[0039] When the smoke guide plate 123 is in the closed state to seal the smoke inlet 121b, the length direction of the smoke guide plate 123 is parallel to the first direction, the width direction of the smoke guide plate 123 is parallel to the third direction, and the thickness direction of the smoke guide plate 123 is parallel to the second direction. When the smoke guide plate 123 is in the open state to open the smoke inlet 121b, the smoke guide plate 123 and the outer casing 121 form a certain angle, and this angle is preferably an acute angle. Therefore, it can block the oil fumes at the smoke inlet 121b to prevent the oil fumes from escaping.

[0040] It is understood that the shape of the smoke guide plate 123 is not limited to this, and can be set as needed to meet different requirements. Furthermore, the smoke guide plate 123 can be a plate-like structure made of glass, metal, or other materials. Preferably, the smoke guide plate 123 is a glass plate, which has high gloss, is aesthetically pleasing, and is not easily stained with oil, thus reducing the frequency of cleaning the smoke guide plate 123.

[0041] The oil cup 127 is located at the bottom of the outer casing 121 at the third-order end away from the suction device 140. The oil fumes flowing into the suction duct 121a, after being filtered, will drip down into the oil cup 127 under the action of gravity.

[0042] As described in the background section, when the smoke guide plate 123 is in the open state, cooking fumes can enter the suction duct 121a through the smoke inlet 121b. The smoke guide plate 123 can block the diffusion of cooking fumes at the smoke inlet 121b, which helps the suction device 140 to remove the cooking fumes. However, since the surface of the smoke guide plate 123 facing the smoke inlet 121b is a flat slope, some cooking oil escapes along the surface of the smoke guide plate 123 facing the smoke inlet 121b, thus affecting the smoke extraction effect of the range hood.

[0043] Combination Figure 3 and Figure 4 As shown, Figure 2 This diagram shows a structural schematic of the air guide plate and the blocking member 125 in one embodiment of this application. Figure 2 The diagram shows a structural schematic of the air guide plate and the blocking member 125 from another angle in one embodiment of this application. To solve the above-mentioned technical problems, the smoke guiding device 120 of this application also includes a blocking member 125. The blocking member 125 includes a mounting plate 1252 and a smoke blocking structure 1254. The mounting plate 1252 is disposed on the side surface of the smoke guide plate 123 facing the smoke inlet 121b. One side of the smoke blocking structure 1254 is connected to the mounting plate 1252, and the other side of the smoke blocking structure 1254 extends in a direction away from the smoke guide plate 123.

[0044] Thus, the presence of the smoke-blocking structure 1254 of the blocking member 125 obstructs and disrupts the escape route of the oil fumes. The oil fumes cannot escape along the edge of the smoke guide plate 123 due to the obstruction of the smoke-blocking structure 1254. When the obstructed and disrupted oil fumes swirl in the air, they can be sucked into the suction duct 121a by the suction device 140, thereby improving the smoke extraction effect of the range hood.

[0045] Please continue reading. Figure 1 , Figure 3 as well as Figure 4 Specifically, in some embodiments, the mounting plate 1252 has a rectangular plate-like structure. The length direction of the mounting plate 1252 is parallel to the length direction of the smoke guide plate 123, and the width direction of the mounting plate 1252 is parallel to the width direction of the smoke guide plate 123. The smoke-blocking structure 1254 surrounds at least a portion of the edge of the mounting plate 1252 in the circumferential direction, including a first smoke-blocking structure 1254a, a second smoke-blocking structure 1254b, a third smoke-blocking structure 1254c, and a fourth smoke-blocking structure 1254d. The first smoke-blocking structure 1254a, the second smoke-blocking structure 1254b, the third smoke-blocking structure 1254c, and the fourth smoke-blocking structure 1254d are all elongated structures, and the first smoke-blocking structure 1254a, the third smoke-blocking structure 1254c, the second smoke-blocking structure 1254b, and the fourth smoke-blocking structure 1254d are connected end to end in the circumferential direction around the edge of the mounting plate 1252, thereby forming a closed square frame structure.

[0046] The first smoke-blocking structure 1254a and the second smoke-blocking structure 1254b are respectively connected to opposite sides of the mounting plate 1252 in the width direction. The first smoke-blocking structure 1254a is located on the side of the mounting plate 1252 near the connection end between the smoke guide plate 123 and the outer casing 121, and extends longitudinally along the first direction. The length of the first smoke-blocking structure 1254a is approximately the same as the length of the mounting plate 1252. The second smoke-blocking structure 1254b is located on the side of the mounting plate 1252 away from the connection end between the smoke guide plate 123 and the outer casing 121, and extends longitudinally along the first direction. The length of the second smoke-blocking structure 1254b is approximately the same as the length of the mounting plate 1252.

[0047] The third smoke-blocking structure 1254c and the fourth smoke-blocking structure 1254d are located on opposite sides of the mounting plate 1252 along its length. The third smoke-blocking structure 1254c is connected between one end of the first smoke-blocking structure 1254a and one end of the second smoke-blocking structure 1254b. The third smoke-blocking structure 1254c extends longitudinally along the width of the mounting plate 1252, and its length is approximately the same as the width of the mounting plate 1252. The fourth smoke-blocking structure 1254d is connected between the other end of the first smoke-blocking structure 1254a and the other end of the second smoke-blocking structure 1254b. The fourth smoke-blocking structure 1254d extends longitudinally along the width of the mounting plate 1252, and its length is approximately the same as the width of the mounting plate 1252.

[0048] like Figure 1 As shown, during the operation of the range hood, the smoke guide plate 123 is in the open state to open the smoke inlet 121b. Most of the oil fumes enter the suction duct 121a along trajectory a under the suction force of the suction device 140. Some of the oil fumes that attempt to escape along the surface of the smoke guide plate 123 enter the suction duct 121a along trajectory b under the obstruction of the second smoke baffle structure 1254b. Another part of the oil fumes that may escape enter the suction duct 121a along trajectory c under the obstruction of the first smoke baffle structure 1254a. The remaining oil fumes that may escape can also enter the suction duct 121a under the obstruction of the third smoke baffle structure 1254c and the fourth smoke baffle structure 1254d.

[0049] As can be seen, the multiple barriers of the smoke guide plate 123, the first smoke-blocking structure 1254a, the second smoke-blocking structure 1254b, the third smoke-blocking structure 1254c, and the fourth smoke-blocking structure 1254d effectively prevent the oil fumes at the smoke inlet 121b from escaping outwards, allowing more oil fumes to enter the suction duct 121a, thereby improving the smoke extraction effect of the range hood.

[0050] It is understood that the smoke-blocking structure 1254 may include any one or more of the first smoke-blocking structure 1254a, the second smoke-blocking structure 1254b, the third smoke-blocking structure 1254c, and the fourth smoke-blocking structure 1254d. The length and width of the smoke-blocking structure 1254 can be selected to be as large as possible while meeting assembly requirements, thereby increasing the contact area with the oil fumes and thus achieving a better blocking effect on the oil fumes. For example, in some embodiments, the smoke-blocking structure 1254 may only include the first smoke-blocking structure 1254a, and in other embodiments, the smoke-blocking structure 1254 may only include the first smoke-blocking structure 1254a and the second smoke-blocking structure 1254b, both of which can play a certain role in preventing the escape of oil fumes.

[0051] Please refer to it again. Figure 2 , Figure 3 as well as Figure 4In some embodiments, the first smoke-blocking structure 1254a extends downward at an angle from one end of the connecting mounting plate 1252 to the end away from the mounting plate 1252. It also extends at an angle towards the second smoke-blocking structure 1254b. Thus, when the smoke guide plate 123 is in the closed state and closes the smoke inlet 121b, the first smoke-blocking structure 1254a extends obliquely downward towards the oil cup 127. Residual oil generated by the range hood module 100 during operation can drip onto the first smoke-blocking structure 1254a, which can guide the oil droplets into the oil cup 127.

[0052] It is understood that the specific shape of the first smoke-blocking structure 1254a is not limited. Specifically, in some embodiments, the first smoke-blocking structure 1254a is formed by splicing two inclined surfaces with different slopes in its inclined extension direction. The two inclined surfaces with different slopes can be formed by bending, so the manufacturing process is relatively simple. In other embodiments, the first smoke-blocking structure 1254a may also be a smooth arc surface extending downward.

[0053] In some embodiments, from one end of the connecting mounting plate 1252 to the end away from the mounting plate 1252, the second smoke-blocking structure 1254b extends obliquely away from the first smoke-blocking structure 1254a. Thus, when the smoke guide plate 123 is in the closed state and the smoke inlet 121b is closed, the second smoke-blocking structure 1254b extends obliquely downward toward the oil cup 127, and residual oil generated by the range hood module 100 during operation can drip onto the second smoke-blocking structure 1254b, which can guide the oil droplets into the oil cup 127.

[0054] It is understood that the specific shape of the second smoke-blocking structure 1254b is not limited. In some embodiments, the second smoke-blocking structure 1254b is formed by splicing two inclined surfaces with different slopes in its inclined extension direction. The two inclined surfaces with different slopes can be formed by bending, so the manufacturing process is relatively simple. In other embodiments, the second smoke-blocking structure 1254b may also be a smooth arc surface extending downward.

[0055] In some embodiments, an adhesive layer is provided between the mounting plate 1252 and the smoke guide plate 123. The adhesive layer can be formed by curing an adhesive, thereby fixing the blocking member 125 relative to the smoke guide plate 123 so as to rotate synchronously with the fixing plate. It is understood that the fixing method of the blocking member 125 and the smoke guide plate 123 is not limited. In other embodiments, the blocking member 125 and the smoke guide plate 123 can also be connected by snap-fit ​​connection, fastener connection, or other methods.

[0056] Furthermore, the mounting plate 1252 has a protrusion 1252a protruding toward the smoke guide plate 123. The protrusion 1252a contacts the smoke guide plate 123 to provide support. A gap exists between the part of the mounting plate 1252 without the protrusion 1252a and the smoke guide plate 123 to leave a filling space for the adhesive layer. Thus, the adhesive layer fills the gap between the mounting plate 1252 and the smoke guide plate 123, which increases the bonding strength while preventing glue overflow.

[0057] In a preferred embodiment, the mounting plate 1252 has a plurality of protrusions 1252a, each protrusion 1252a having a circular cross-section, and the plurality of protrusions 1252a are spaced apart on one side surface of the mounting plate 1252 body. It is understood that the number, shape, and position of the protrusions 1252a are not limited and can be configured as needed to meet different requirements.

[0058] The aforementioned smoke guiding device 120, range hood module 100, and range hood, by setting a blocking member 125 on the smoke guiding plate 123 of the smoke guiding device 120, can effectively prevent the oil fumes generated during cooking from escaping along the surface of the smoke guiding plate 123, and at the same time guide the oil stains into the oil cup 127, effectively preventing oil fume leakage and improving the environment of the kitchen where the range hood is located.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
