Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of kitchen appliances, and in particular to a range hood. Background Art
[0002] As a kitchen appliance, a range hood is widely used in daily life. A stove is arranged under the range hood or in a corresponding area thereof. When a user cooks on the stove, oil smoke is generated, and the range hood absorbs the oil smoke.
[0003] In one implementation, an oil net is provided in the range hood corresponding to the two stoves. When any one stove or both stoves are operated, the range hood is turned on to absorb the oil smoke generated by the stoves.
[0004] However, a single oil net corresponds to two stoves. When one stove, for example, the left stove, is turned on, or when two stoves are turned on at the same time but the oil fumes generated by the two stoves are quite different, for example, the left stove generates more oil fume and the right stove generates less oil fume. After the range hood is turned on, the oil net parts corresponding to the left stove and the right stove have the same ability to absorb oil fumes, so that the oil fume corresponding to the right stove cannot be completely absorbed, and the absorption capacity of the range hood in the areas corresponding to the two stoves cannot be individually and specifically adjusted, and the oil fume absorption effect of the range hood cannot be improved.

[0038] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.
[0039] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and other forms thereof, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open, inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the present embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics described may be included in any one or more embodiments or examples in any appropriate manner.
[0040] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.
[0041] “At least one of A, B, and C” has the same meaning as “at least one of A, B, or C” and both include the following combinations of A, B, and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B, and C.
[0042] Additionally, the use of “based on” is meant to be open and inclusive, as a process, step, calculation, or other action “based on” one or more stated conditions or values may, in practice, be based on additional conditions or values beyond those stated.
[0043] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within the acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism may be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity may also be, for example, a deviation within 5°.

[0044] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the areas of the regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are conceivable. Therefore, the exemplary embodiments should not be interpreted as being limited to the shapes of the regions shown herein, but include shape deviations due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of the regions of the device, and are not intended to limit the scope of the exemplary embodiments.
[0045] like Figure 1 to Figure 4 As shown, the embodiment of the present disclosure provides a range hood 100, which includes a housing 10 and an oil net assembly 20. The housing 10 is surrounded by a structure with an inner cavity, and the housing 10 has a smoke inlet, which is used to absorb external oil smoke into the housing 10.
[0046] The housing 10 includes a guide plate 11 disposed opposite to the smoke inlet. The oil smoke entering the housing 10 through the smoke inlet flows into the housing 10 after being guided by the guide plate 11.
[0047] like Figure 1 As shown, the oil net assembly 20 is connected to the housing 10 to cover the smoke inlet. For example, the oil net assembly 20 is connected to the housing 10 on two opposite sides or around. The oil net assembly 20 covers the smoke inlet, so that the oil smoke entering the housing 10 must pass through the oil net assembly 20.
[0048] Specifically, combined Figure 3 and Figure 4 The oil net assembly 20 includes: an outer oil net 21, a first inner net 22, a second inner net 23, at least two sets of reset assemblies 24, at least two sets of guide rail assemblies 25 and a drive assembly 26.
[0049] The outer oil net 21 is relative to the inner oil net, and is located outside the range hood 100. The outer oil net 21 is connected to the housing 10, and includes a first sub-section 211 and a second sub-section 212 that are connected to each other. The first sub-section 211 and the second sub-section 212 are an integral structure. The first sub-section 211 and the second sub-section 212 both have outer mesh holes 28. The outer mesh holes 28 are passages for oil smoke to pass through the outer oil net 21.
[0050] For example, the number of external oil holes on the first sub-section 211 is multiple. The number of external oil holes on the second sub-section 212 is multiple. The shapes of the external oil holes on the first sub-section 211 and the second sub-section 212 can be the same, for example, both are long strips. The multiple long strip-shaped external oil holes are arranged in parallel and spaced in sequence.
[0051] like Figure 4 and Figure 5 As shown, the inner oil net includes a first inner net 22 and a second inner net 23. The first inner net 22 is located on a side of the first sub-section 211 close to the guide plate 11, and the first inner net 22 is arranged corresponding to the first sub-section 211. The first inner net 22 and the second inner net 23 are located on the same plane.
[0052] The second inner net 23 is located on one side of the second sub-portion 212 close to the guide plate 11, and is disposed correspondingly to the second sub-portion 212. The first inner net 22 has a plurality of inner oil holes, and the second inner net 23 has a plurality of inner oil holes.
[0053] The first inner net 22 and the second inner net 23 both have inner net holes 27. The shapes of the inner oil holes on the first inner net 22 and the second inner net 23 can be the same, and the shape of the inner net holes 27 is, for example, a long strip.
[0054] For example, the size of the inner mesh 27 and the size of the outer mesh 28 can be the same. The number of the inner mesh 27 on the first inner mesh 22 is the same as the number of the outer mesh 28 on the first sub-section 211, and the spacing between two adjacent inner meshes 27 on the first inner mesh 22 is the same as the spacing between two adjacent outer meshes 28 on the first sub-section 211. Thus, the plurality of inner meshes 27 on the first inner mesh 22 and the plurality of outer meshes 28 on the first sub-section 211 can be directly opposite (e.g., Figure 5 The first intranet 22 in the network).
[0055] The number of inner mesh holes 27 on the second inner net 23 is the same as the number of outer mesh holes 28 on the second sub-section 212, and the spacing between two adjacent inner mesh holes 27 on the second inner net 23 is the same as the spacing between two adjacent outer mesh holes 28 on the second sub-section 212. Thus, the plurality of inner mesh holes 27 on the second inner net 23 and the plurality of outer mesh holes 28 on the second sub-section 212 can be directly opposite (e.g., Figure 6 The second intranet 23).
[0056] The range hood 100 provided in the embodiment of the present disclosure includes a shell 10 and an oil net assembly 20, wherein the oil net assembly 20 includes an outer oil net 21, a first inner net 22 and a second inner net 23, the outer oil net 21 includes a first sub-portion 211 corresponding to the first inner net 22, and a second sub-portion 212 corresponding to the second inner net 23, thereby dividing the smoke inlet of the range hood 100 into two, so that the oil smoke in the area corresponding to the first sub-portion 211 can enter the shell 10 from the first sub-portion 211 and the first inner net 22, and the oil smoke in the area corresponding to the second sub-portion 212 can enter the shell 10 from the second sub-portion 212 and the second inner net 23, so that the range hood 100 presents two smoke inlet channels, and the smoke inlet is separated, so that the oil fume extraction operation can be performed in different areas.
[0057] like Figure 3 As shown, the number of reset components 24 can be multiple groups, such as two groups or four groups. At least one group of reset components 24 abuts against one end of the first inner net 22, for example, the reset component 24 abuts against one end of the first inner net 22 away from the second inner net 23. At least one group of reset components 24 abuts against one end of the second inner net 23, for example, the reset component 24 abuts against one end of the second inner net 23 away from the first inner net 22.
[0058] When there are four groups of reset components 24 , two groups of reset components 24 abut against the same end of a first inner net 22 , and the other two groups of reset components 24 abut against the same end of a second inner net 23 .
[0059] There may be multiple groups of guide rail assemblies 25. At least two groups of guide rail assemblies 25 are located on the inner side of the outer oil net 21. Here, the inner side of the outer oil net 21 refers to the side of the outer oil net 21 close to the inner oil net.
[0060] Exemplarily, when the range hood 100 includes two sets of guide rail assemblies 25, the two sets of guide rail assemblies 25 are respectively located on opposite sides of the outer oil net 21, for example, located on the upper and lower sides of the outer oil net 21. The upper and lower sides of the first inner net 22 are respectively connected to the two sets of guide rail assemblies 25 and can slide relative to the guide rail assemblies 25, and the upper and lower sides of the second inner net 23 are respectively connected to the two sets of guide rail assemblies 25 and can slide relative to the guide rail assemblies 25.
[0061] For example, when the range hood 100 includes four sets of guide rail assemblies 25, two sets of guide rail assemblies 25 are respectively located at the upper and lower sides of the left side of the outer oil net 21, and the other two sets of guide rail assemblies 25 are respectively located at the upper and lower sides of the right side of the outer oil net 21. The upper and lower sides of the first inner net 22 are respectively connected to the two sets of guide rail assemblies 25 on the left side and can slide relative to the guide rail assemblies 25, and the upper and lower sides of the second inner net 23 are respectively connected to the two sets of guide rail assemblies 25 on the right side and can slide relative to the guide rail assemblies 25.
[0062] like Figure 5 As shown, the driving assembly 26 is connected to the guide plate 11 and is located between the first inner net 22 and the second inner net 23 .
[0063] The driving component 26 and the resetting component 24 are configured to drive the first inner net 22 to slide on the guide rail component 25 so that the inner mesh holes 27 of the first inner net 22 are opposite to or offset from the outer mesh holes 28 of the first sub-section 211; and to drive the second inner net 23 to slide on the guide rail component 25 so that the inner mesh holes 27 of the second inner net 23 are opposite to or offset from the outer mesh holes 28 of the second sub-section 212.
[0064] For example, Figure 3 As shown, the drive assembly 26 and the reset assembly 24 are configured to drive the first inner net 22 to slide on the guide rail assembly in a direction close to the second inner net 23, so that the inner mesh holes 27 of the first inner net 22 are opposite to the outer mesh holes 28 of the first sub-section 211, for example, one inner mesh hole 27 is opposite to one outer mesh hole 28, so that external oil smoke can enter the interior of the shell 10 through the outer mesh holes 28 of the first sub-section 211 and the inner mesh holes 27 of the first inner net 22.
[0065] For example, Figure 6 and Figure 7 As shown, the drive assembly 26 and the reset assembly 24 are also configured to drive the second inner net 23 to slide on the guide rail assembly in a direction close to the first inner net 22, so that the inner mesh holes 27 of the second inner net 23 are opposite to the outer mesh holes 28 of the second sub-section 212, for example, one inner mesh hole 27 is opposite to one outer mesh hole 28, so that external oil smoke can enter the interior of the shell 10 through the outer mesh holes 28 of the second sub-section 212 and the inner mesh holes 27 of the second inner net 23.
[0066] For example, Figure 6 and Figure 7 As shown, the drive assembly 26 and the reset assembly 24 are also configured to: drive the first inner net 22 to move on the guide rail assembly in a direction away from the second inner net 23, so that the inner mesh holes 27 of the first inner net 22 are partially staggered with the outer mesh holes 28 of the first sub-section 211, for example, an inner mesh hole 27 is partially opposite to an outer mesh hole 28, so that when there is less oil smoke facing the first sub-section 211, the oil smoke can enter the interior of the shell 10 through the outer mesh holes 28 of the first sub-section 211 and the inner mesh holes 27 of the first inner net 22.
[0067] For example, Figure 5As shown, the drive assembly 26 and the reset assembly 24 are also configured to: drive the second inner net 23 to move on the guide rail assembly in a direction close to the first inner net 22, so that the inner mesh holes 27 of the second inner net 23 are partially staggered with the outer mesh holes 28 of the second sub-section 212, for example, an inner mesh hole 27 is partially opposite to an outer mesh hole 28, so that when there is less oil smoke facing the second sub-section 212, the oil smoke can enter the interior of the shell 10 through the outer mesh holes 28 of the second sub-section 212 and the corresponding inner mesh holes 27 of the second inner net 23.
[0068] Therefore, the range hood 100 provided in the embodiment of the present disclosure, using the reset component 24, the drive component 26 and the guide rail component 25, can realize the movement of the first inner net 22 relative to the first sub-section 211, and the movement of the second inner net 23 relative to the second sub-section 212, and then the facing area of the outer mesh holes 28 and the inner mesh holes 27 can be adjusted, so that the oil fume absorption capacity corresponding to the first sub-section 211 and the oil fume absorption capacity corresponding to the second sub-section 212 can be independently controlled and adjusted, so that the range hood 100 has a stronger oil fume absorption capacity for areas with a larger amount of oil fume, thereby improving the oil fume absorption effect of the range hood 100.
[0069] The at least two groups of reset components 24 may include: a first reset component 241 and a second reset component 242. The first reset component 241 abuts against one end of the first inner net 22, and the second reset component 242 abuts against one end of the second inner net 23. The structure of the first reset component 241 may be the same as that of the second reset component 242. The reset component 24 is described below taking the structure of the first reset component 241 as an example.
[0070] In some examples, such as Figure 8 to Figure 10 As shown, the first resetting assembly 241 includes: a body cavity 243 , a mounting portion 244 , a guide column 245 , an elastic member 246 and a limiting member 247 .
[0071] The body cavity 243 is a hollow cavity structure. The mounting portion 244 is located on one side of the body cavity 243 close to the first inner net 22. The mounting portion 244 may be a hole-shaped structure.
[0072] One end of the guide post 245 abuts against the first inner net 22, and the other end of the guide post 245 passes through the mounting portion 244 into the body cavity 243, and the guide post 245 is slidably connected to the mounting portion 244. The axial direction of the guide post 245 is parallel to the extension direction of the guide rail assembly 25, so that the guide post 245 can drive the first inner net 22 to slide on the guide rail assembly 25.
[0073] The elastic member 246 is located in the body cavity 243, and one end of the elastic member 246 is connected to the guide post 245. The elastic member 246 can be deformed under the action of an external force, thereby driving the guide post 245 to move.
[0074] The limiting member 247 is located in the body cavity 243 and connected to the body cavity 243. The limiting member 247 is also connected to the other end of the elastic member 246. The limiting member 247 can be a columnar structure, and the limiting member 247 fixes one end of the elastic member 246.
[0075] With the above arrangement, when the first inner net 22 is driven by the driving assembly 26 to press the first reset assembly 241, the guide post 245 of the first reset assembly 241 is pressed and moves relative to the mounting portion 244 toward the inside of the body cavity 243, thereby pressing the elastic member 246, so that the elastic member 246 is compressed (such as Fig.10 When the driving assembly 26 stops driving the first inner net 22, the elastic member 246 returns to its original state (as shown in FIG. Figure 8 As shown), the guide column 245 is driven to move in the mounting portion 244 toward the outside of the main body cavity 243, and the guide column 245 drives the first inner net 22 to move, thereby realizing the driving of the first inner net 22 by the guide column 245, and realizing the movement of the first inner net 22 relative to the first sub-portion 211, so that the facing area of the outer mesh hole 27 and the inner mesh hole 28 changes, thereby adjusting the smoke intake of the first sub-portion 211 and the first inner net 22, and adjusting or controlling the smoke extraction effect of the range hood 100.
[0076] For example, Figure 8 to Figure 10 As shown, the elastic member 246 includes a spring. Thus, the elastic member 246 can be easily obtained, the cost of the elastic member 246 is relatively low, and the elasticity of the spring is easy to recover.
[0077] In some examples, such as Figure 8 As shown, the guide column 245 includes a guide portion 2451 and a stop portion 2452 that are connected to each other.
[0078] The guide portion 2451 passes through the mounting portion 244, and the stop portion 2452 is located in the body cavity 243, and the stop portion 2452 is connected to the spring. The radial dimension of the guide portion 2451 is smaller than the radial dimension of the stop portion 2452. Therefore, the stop portion 2452 is used to limit the moving distance of the guide portion 2451, so as to prevent the elastic force of the elastic member 246 from being too large and completely pushing the guide portion 2451 out of the body cavity 243.
[0079] In some examples, such as Fig.10 As shown, the first resetting assembly 241 further includes a fixing member 2411 . The fixing member 2411 includes a screw and a first mounting hole 2413 .
[0080] like Figures 11 to 17As shown, the outer oil net 21 includes: a mounting member 213 located on the side of the first sub-section 211 away from the second sub-section 212, the mounting member 213 has a first sub-mounting member 2131 connected to the first sub-section 211, and a second sub-mounting member 2132 connected to the first sub-mounting member 2131. The second sub-mounting member 2132 is parallel to the first sub-section 211. Fig.17 As shown, the first sub-mounting member 2131 and the second sub-mounting member 2132 are both flat plate structures, and the first sub-portion 211, the first sub-mounting member 2131, and the second sub-mounting member 2132 are roughly in a "U" shape.
[0081] like Fig.12 As shown, a second mounting hole 2133 is provided on the second sub-mounting member 2132 .
[0082] like Fig.17 As shown, a portion of the main body cavity 243 in the first reset component 241 is located between the second sub-mounting member 2132 and the first sub-portion 211, the first mounting hole 2413 is directly opposite to the second mounting hole 2133, and the screw passes through the second mounting hole and extends into the first mounting hole 2413, thereby installing the first reset component 241 on the outer oil net 21, so that the connection between the first reset component 241 and the outer oil net 21 is more firm.
[0083] The at least two groups of guide rail assemblies 25 may include: a first guide rail assembly 25 and a second guide rail assembly 25. The first inner net 22 is slidably connected to the first guide rail assembly 25, and the second inner net 23 is slidably connected to the second guide rail assembly 25. The structure of the first guide rail assembly 25 may be the same as that of the second guide rail assembly 25. The guide rail assembly 25 is described below by taking the structure of the first guide rail assembly 25 as an example.
[0084] For example, Fig.13 As shown, the first guide rail assembly 25 includes a guide rail portion 251 connected to the inner side of the outer oil net 21 .
[0085] For example, the guide rail portion 251 is connected to the outer oil net 21 by screws. Fig.18 and Fig.19 As shown, the guide rail portion 251 extends in the horizontal direction, and the cross-sectional shape of the guide rail portion 251 in a direction perpendicular to the extending direction thereof is substantially "U"-shaped or "C"-shaped.
[0086] like Fig.18 As shown, the first inner net 22 includes: an inner net portion 221 and a sliding member 222 , the sliding member 222 is connected to the inner net portion 221 , and the sliding member 222 is slidably connected to the guide rail portion 251 .
[0087] For example, the sliding member 222 includes a sliding head and a connecting portion connected to each other, the sliding head is slidably connected to the guide rail portion 251, and the connecting portion is fixedly connected to the inner net portion 221. The diameter of the sliding head is larger than the diameter of the connecting portion, and the diameter of the sliding head matches the size of the guide rail portion 251.
[0088] In some examples, such as Fig.13 As shown, the first guide rail assembly 25 further includes a limiting portion 252 .
[0089] The limiting portion 252 is located on one side of the guide rail portion 251 close to the driving assembly 26 and is connected to the guide rail portion 251. The limiting portion 252 protrudes from the guide rail portion 251. When the sliding member 222 slides to the limiting portion 252, the limiting portion 252 blocks the sliding member 222 from sliding further. The limiting portion 252 is used to limit the sliding displacement of the sliding member 222 to prevent the sliding member 222 from escaping from the slide rail.
[0090] In some examples, such as Fig.21 As shown, the first inner net 22 further includes: an abutment portion 223. The abutment portion 223 may be a groove-shaped structure.
[0091] When the first inner net 22 holes of the first inner net 22 are directly opposite to the outer net holes 28 of the first sub-section 211, the abutting portion 223 abuts against the limiting member 247. Thus, the first inner net 22 can be prevented from shaking relative to each other.
[0092] In some examples, such as Figure 5 As shown, the driving assembly 26 includes a rocker arm 261 and a driving portion 262 .
[0093] like Fig. 20 As shown, the rocker arm 261 has a first rod 263 and a second rod 264 connected to each other, and there is a certain angle between the first rod 263 and the second rod 264. The first rod 263 is close to the first inner net 22, and the first rod 263 extends in a direction close to the first inner net 22. The second rod 264 is close to the second inner net 23, and the second rod 264 extends in a direction close to the second inner net 23.
[0094] The driving part 262 is connected to the rocker arm 261. The driving part 262 is used to drive the first rod 263 of the rocker arm 261 to move in a direction close to the first inner net 22, and drive the first inner net 22 to move. The driving part 262 is also used to drive the second rod 264 of the rocker arm 261 to move in a direction close to the second inner net 23, and drive the second inner net 23 to move.
[0095] For example, when the two stoves corresponding to the range hood 100 are turned on, oil smoke will be generated in the area corresponding to the first sub-section 211 and the second sub-section 212. For example, the left stove generates more oil smoke, while the right stove generates less oil smoke. The smoke inlet corresponding to the left stove needs to absorb more oil smoke, and the first rod 263 of the rocker arm 261 of the driving component 26 does not contact the first inner net 22, and does not apply driving force to the first inner net 22. The guide column 245 of the reset component 24 abuts against the first inner net 22, or there is no force between the guide column 245 and the first inner net 22, and they only contact each other, the elastic member 246 is in a stretched state or original state, and the inner mesh hole 28 of the first inner net 22 is opposite to the outer mesh hole 27 of the first sub-section 211, so that more oil smoke can enter the housing 10 through the outer mesh hole 27 of the first sub-section 211 and the inner mesh hole 28 of the first inner net 22, so that the range hood 100 has a better oil smoke absorption effect.
[0096] The smoke inlet corresponding to the right stove needs to absorb less oil smoke, and the second rod 264 of the rocker arm 261 of the driving assembly 26 applies a horizontal leftward driving force to the second inner net 23, and the second inner net 23 slides to the left on the guide rail assembly 25. The guide column 245 of the reset assembly 24 abuts against the second inner net 23, and the elastic member 246 is compressed. The inner mesh holes 28 of the second inner net 23 are partially staggered with the outer mesh holes 27 of the second sub-section 212, and the smoke intake area is reduced, so that less oil smoke enters the shell 10 through the outer mesh holes 27 of the first sub-section 211 and the inner mesh holes 28 of the first inner net 22, thereby avoiding waste of power consumption of the range hood 100.
[0097] Of course, when the amount of oil smoke that needs to be sucked out of the smoke inlet corresponding to the right stove increases, the second rod 264 of the rocker arm 261 of the driving assembly 26 moves away from the second inner net 23 and separates from the second inner net 23. At the same time, the elastic member 246 returns to its original shape, pushing the second inner net 23 to slide rightward on the guide rail assembly 25, so that the inner mesh holes 28 of the second inner net 23 are directly opposite to the outer mesh holes 27 of the second sub-section 212, so that more oil smoke enters the housing 10 through the outer mesh holes 27 of the first sub-section 211 and the inner mesh holes 28 of the first inner net 22. In this way, the smoke intake of the first sub-section 211 and the second sub-section 212 is controlled separately, so that the range hood 100 consumes a large amount of energy and improves the oil smoke suction effect of the range hood 100.

Any changes or substitutions that can be thought of by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure.
