Abstract

The present invention provides a smoke collection structure and a range hood, which relate to the technical field of kitchen appliances. The baffle in this solution is arranged on the inside of the smoke hood rather than the outside, so the baffle will not block the user's line of sight. In addition, the oil stains on the baffle will also fall from top to bottom along the surface of the baffle into the inside of the smoke hood and then flow into the oil cup, rather than falling on the stove, thereby making the stove cleaner. Secondly, the baffle is movably connected to the smoke hood, and the smoke intake of the smoke collection structure can be changed by changing the state of the baffle to adapt to different cooking scenarios. In addition, in order to prevent the baffle from directly contacting the rear panel when in the second state, causing the oil stains on the rear panel to flow onto the front of the baffle, in this application, a partition structure is provided between the baffle and the rear panel, so that the oil stains flowing down the rear panel can flow into the oil cup below the smoke hood through the first oil guide gap formed between the baffle and the rear panel.

Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a smoke collecting structure and a range hood. Background Art

[0002] The range hood has become one of the essential appliances in the kitchen. The range hood consists of a fume hood, a baffle and a fan assembly. The baffle is connected to the fume hood and acts as a guide to guide the fume into the fan assembly.

[0003] Currently, the baffles on range hoods on the market are typically located outside the fume hood. This type of machine has two drawbacks: First, the baffle obstructs vision, reducing user satisfaction. Second, during use, oil stains adhering to the surface of the baffle can flow down to the bottom of the panel, creating a risk of oil dripping over time. Summary of the Invention

[0004] The object of the present invention is to provide a smoke collection structure and a range hood to alleviate the technical problems in existing range hoods, such as the outward-turned baffle blocking the view and the oil stains on the baffle dripping onto the stove.

[0005] In a first aspect, the present invention provides a smoke collection structure comprising: a smoke collection hood and a baffle, wherein the smoke collection hood has a front panel and a rear panel, the front panel is provided with a smoke inlet communicating with the outside; the baffle is located on the inner side of the smoke inlet;

[0006] The baffle is movably connected to the smoke collecting hood, and the baffle has a first state and a second state. In the first state and the second state, the baffle and the smoke inlet respectively form a first smoke inlet channel and a second smoke inlet channel, and the air intake of the first smoke inlet channel is less than the air intake of the second smoke inlet channel.

[0007] A partition structure is provided on the smoke collecting hood and / or the baffle. In the second state, the partition structure is located between the baffle and the rear panel and is used to separate a first oil guide gap between the baffle and the rear panel.

[0008] Furthermore, a rotary drive mechanism is provided on the smoke hood, and the back of the baffle has a support arm extending in the up and down directions, and the movable end of the rotary drive mechanism is connected to the bottom end of the support arm; when the baffle is in the second state, the top end of the support arm abuts against the rear panel.

[0009] Furthermore, along a direction perpendicular to the front panel, a lower edge of a projection of the baffle toward the front panel is located below the smoke inlet.

[0010] Furthermore, when the baffle is in the first state, the baffle is spaced apart from the front panel along a direction perpendicular to the front panel.

[0011] Furthermore, the smoke collection structure includes a rotation drive mechanism and a translation drive mechanism; the translation drive mechanism is connected to the smoke collection hood, and the rotation drive mechanism is connected to the movable end of the translation drive mechanism; the movable end of the rotation drive mechanism is connected to the bottom of the baffle, and the rotation drive mechanism drives the baffle to swing in the front-to-back direction to switch it between the first state and the second state;

[0012] The translation drive mechanism is used to drive the rotation drive mechanism and the baffle to translate toward or away from the front panel of the smoke collecting hood, so that the baffle can fit with the back of the front panel to completely close the smoke inlet.

[0013] Furthermore, the smoke collection structure further includes a fan assembly and a filter, and the filter is located between the fan assembly and the smoke collection hood.

[0014] Furthermore, the rear edge of the filter is connected to the rear panel, and from front to back, the filter is inclined downward.

[0015] Furthermore, an oil scraping assembly is provided on the back of the baffle, and the oil scraping assembly includes a scraper spaced apart from the baffle;

[0016] The surface that the top of the scraper passes through during the switching of the baffle from the first state to the second state is consistent with the shape of the bottom surface of the filter, so that the top of the scraper abuts against the bottom surface of the filter during the state switching process;

[0017] A second oil guide gap is formed between the scraper and the back surface of the baffle, and when the baffle is in the second state, the scraper is spaced apart from the rear panel under the support of the partition structure.

[0018] Furthermore, the back of the fan assembly has an air inlet, and from top to bottom, the fan assembly is tilted forward.

[0019] In a second aspect, the present invention provides a range hood comprising the above-mentioned smoke collecting structure.

[0020] The present invention has at least the following advantages or beneficial effects:

[0021] The smoke collecting structure provided by the present invention includes: a smoke collecting hood and a baffle, the smoke collecting hood having a front panel and a rear panel, the front panel being provided with a smoke inlet connected to the outside world; the baffle being located on the inner side of the smoke inlet; the baffle being movably connected to the smoke collecting hood, the baffle having a first state and a second state, in the first state and the second state, the baffle and the smoke inlet respectively form a first smoke inlet channel and a second smoke inlet channel, and the air intake volume of the first smoke inlet channel is smaller than the air intake volume of the second smoke inlet channel; a partition structure is provided on the smoke collecting hood and / or the baffle, in the second state, the partition structure is located between the baffle and the rear panel, and is used to separate a first oil guide gap between the baffle and the rear panel.

[0022] First, unlike the prior art, the baffle in this solution is set on the inside of the smoke hood instead of the outside, so the baffle will not block the user's line of sight. In addition, the oil stains on the baffle will also fall from top to bottom along the surface of the baffle into the inside of the smoke hood and then flow into the oil cup, instead of falling on the stove, thereby making the stove cleaner. Secondly, the baffle is movably connected to the smoke hood. By changing the state of the baffle, the smoke intake of the smoke collection structure can be changed to adapt to different cooking scenarios. In addition, in order to prevent the baffle from directly contacting the rear panel when in the second state, causing the oil stains on the rear panel to flow to the front of the baffle, in this application, a partition structure is set between the baffle and the rear panel, so that the oil stains flowing down the rear panel can flow into the oil cup below the smoke hood after passing through the first oil guide gap formed between the baffle and the rear panel.

[0023] The range hood provided by the present invention includes the above-mentioned smoke collecting structure.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figure 1-Figure 4 As shown, the smoke collection structure provided by the present invention includes: a smoke collection hood 100 and a baffle 200. The smoke collection hood 100 has a front panel 110 and a rear panel 120. From top to bottom, the front panel 110 can be tilted toward the rear side; the rear panel 120 is used to connect to the wall and is in a vertical state.

[0051] like Figure 3 and Figure 4 As shown, the front panel 110 is provided with a smoke inlet 111 connected to the outside. Under the action of the fan assembly 510, the oil smoke enters the smoke hood 100 through the smoke inlet 111. The baffle 200 is located on the inner side of the smoke inlet 111. The oil smoke entering the smoke hood 100 will flow along the front of the baffle 200.

[0052] The baffle 200 is movably connected to the smoke hood 100, and can be a rotating connection or a sliding connection. The baffle 200 has a first state and a second state, and the user can change the state of the baffle 200 to match different cooking scenes.

[0053] Specifically, such as Figure 3 As shown, in the first state, the baffle 200 can be located directly behind the smoke inlet 111, parallel to the front panel 110, and at a certain distance from the back of the front panel 110, for example, 8mm-12mm. Under the obstruction of the baffle 200, a first annular smoke inlet channel 130 ( Figure 3 The negative pressure is concentrated around the ring, and when cooking with low smoke, the smoke can be sucked and exhausted by simply starting the fan and without turning the baffle 200. Figure 4 As shown, in the second state, the baffle 200 can move in a direction away from the smoke inlet 111, thereby reducing the shielding ability of the baffle 200 on the smoke inlet 111, and the air intake volume of the second smoke inlet channel 140 formed by the smoke inlet 111 and the baffle 200 is greatly increased, which is suitable for cooking conditions with a lot of oil smoke such as stir-frying. In addition, the baffle 200 can play a diversion role, guiding the oil smoke toward the fan assembly 510 above.

[0054] A partition structure may be provided on the smoke hood 100 or the baffle 200, or both of them may have a partition structure. Figure 4 As shown, in the second state, the partition structure is located between the baffle 200 and the rear panel 120, and is used to separate a first oil guide gap 610 between the baffle 200 and the rear panel 120. Since the baffle 200 needs to move toward the side of the rear panel 120 in the second state, in order to prevent the upper edge of the rear panel 120 from directly contacting the rear panel 120, a partition structure is added between the baffle 200 and the rear panel 120. In this embodiment, the partition structure is provided on the back side of the baffle 200. In other embodiments, the partition structure may also be provided on the rear panel 120. The partition structure may be a vertical strip structure or a small block structure.

[0055] In this embodiment, the number of partition structures can be two, and the two partition structures are arranged at intervals on the left and right sides of the back of the baffle 200. When the baffle 200 is rotated backward to the maximum angle, the baffle 200 is not in direct contact with the rear panel 120, but is pressed against the rear panel 120 through the partition structure. A first oil guide gap 610 is formed between the baffle 200, the two partition structures and the rear panel 120, and the oil on the rear panel 120 can flow downward along the gap into the oil cup 700.

[0056] Unlike existing technologies, the baffle 200 in this solution is located inside the fume hood 100 rather than outside. Therefore, the baffle 200 does not block the user's view. Furthermore, oil stains on the baffle 200 will flow down the surface of the baffle 200 into the fume hood 100 and then into the oil cup 700, rather than onto the stovetop, thus keeping the stovetop cleaner. Secondly, the baffle 200 is movably connected to the smoke hood 100. By changing the state of the baffle 200, the smoke intake of the smoke collection structure can be changed to adapt to different cooking scenarios. In addition, in order to avoid the baffle 200 directly abutting the rear panel 120 when in the second state, causing the oil stains on the rear panel 120 to flow to the front of the baffle 200, in this application, a partition structure is set between the baffle 200 and the rear panel 120, so that the oil stains flowing down from the rear panel 120 can pass through the first oil guide gap 610 formed between the baffle 200 and the rear panel 120, and flow into the oil cup 700 under the smoke hood 100.

[0057] like Figure 6 As shown, the smoke hood 100 is provided with a rotary drive mechanism, and the back of the baffle 200 has a support arm 210 extending in the up and down directions, and the movable end of the rotary drive mechanism is connected to the bottom end of the support arm 210; when the baffle 200 is in the second state, the top end of the support arm 210 abuts against the rear panel 120.

[0058] In this embodiment, Figure 6-Figure 8 As shown, the baffle 200 is driven to swing back and forth by a rotary drive mechanism, wherein the rotary drive mechanism can be a reduction motor 300 fixedly connected to the smoke hood 100. The reduction motor 300 can be set at the bottom position outside the smoke collecting chamber of the smoke hood 100, and the shaft of the reduction motor 300 passes through the circular through hole on the side wall of the smoke hood 100. The reduction motor 300 is connected to the smoke hood 100 by screws. Figure 8As shown, the rotating shaft of the reduction motor 300 is cylindrical as a whole, with limiting planes 310 added on both sides, similar to an elliptical cylinder. A support arm 210 is fixedly connected to the left and right sides of the back of the baffle 200, with a symmetrical design. Flanges are provided on the two short sides of the baffle 200, and a countersunk hole is provided in the middle of the flange, and a circular through hole is designed at the position where it cooperates with the reduction motor 300. The support arm 210 is provided on the inner side of the flange, and a countersunk threaded hole is designed at the position corresponding to the countersunk hole on the flange of the baffle 200, which forms a whole with the baffle 200 after being tightened. An elliptical hole 211 is provided on the support arm 210 where it cooperates with the rotating shaft of the reduction motor 300, and the two have the same shape. Therefore, when the reduction motor 300 rotates, it drives the support arm 210 to rotate, thereby causing the baffle 200 to flip. When the baffle 200 is in the second state, the top of the support arm 210 abuts against the rear panel 120. Therefore, the support arm 210 plays the role of fixing the reduction motor 300 and can also play the role of separating the baffle 200 and the rear panel 120. The thickness of the support arm 210 in the front-to-back direction can be 13mm-17mm.

[0059] like Figure 5 As shown, no matter in the first state or the second state, along the direction perpendicular to the front panel 110, the lower edge of the projection of the baffle 200 toward the front panel 110 is located below the smoke inlet 111, and the oil stains on the baffle 200 can flow along the front or back of the baffle 200 to the bottom position of the smoke collecting chamber of the smoke hood 100, and then flow into the oil cup 700 without dripping onto the stove.

[0060] In this embodiment, when the baffle 200 is in the first state, the baffle 200 is spaced apart from the front panel 110 in a direction perpendicular to the front panel 110. In other practicable solutions, the baffle 200 in the first state may also be completely in contact with the back surface of the front panel 110, thereby completely blocking the smoke inlet 111.

[0061] The smoke collecting structure further includes a fan assembly 510 and a filter 520 . The filter 520 is located between the fan assembly 510 and the smoke collecting hood 100 . The filter 520 cools a portion of the oil smoke, reduces the cooling of oil pollution in the fan assembly 510 , and extends the service life of the fan assembly 510 .

[0062] In this embodiment, Figure 9As shown, the filter 520 is flat and has upward first flanges 521 on all four sides to prevent oil from flowing out from the sides. The filter 520 has multiple strip-shaped holes, and upward second flanges 522 are provided at the edges of the holes, thereby increasing the contact area with the oil smoke and making it easier for the oil smoke to be cooled and liquefied on the filter 520. An oil leakage hole 523 can be provided on the first flange 521 on the rear side of the filter 520. The rear edge of the filter 520 is connected to the rear panel 120, and the filter 520 is tilted downward from front to back, with the tilt angle generally set to 10-20 degrees. The oil on the filter 520 flows out from the oil leakage hole 523 and flows onto the rear panel 120. The oil flows along the rear panel 120 and through the first oil guide gap 610 into the oil cup 700.

[0063] like Figure 4 As shown, the back of the fan assembly 510 has an air inlet, and from top to bottom, the fan assembly 510 is tilted forward. The fan assembly 510 is a fully top-mounted structure, with the back as the main air inlet, and is tilted backward, forming a shape with a small top and a large bottom with the rear panel 120. After the baffle 200 flips inward to the second state, a large cavity is formed in the inner cavity of the smoke hood 100, and the volume increases, forming a negative pressure chamber, where the oil smoke stays briefly. The baffle 200 is tilted toward the rear panel, so a main channel is formed from the smoke inlet 111 to the air inlet of the fan assembly 510. The oil smoke continues to rise along the baffle 200 and finally enters the fan assembly 510, and the oil smoke path is shorter.

[0064] Example 2

[0065] The difference from Example 1 is that, in this embodiment, the baffle 200 can not only swing in the front-to-back direction, but also translate in a direction perpendicular to the front panel 110 , so that the baffle 200 can switch between three different states.

[0066] Specifically, the smoke collection structure includes a rotation drive mechanism and a translation drive mechanism (not shown in the figure), wherein the rotation drive mechanism can be a reduction motor 300, and the reduction motor 300 can be arranged inside the smoke collection hood 100. Similarly, the translation drive mechanism can be a push rod motor, which is also arranged inside the smoke collection hood 100. The translation drive mechanism is fixedly connected to the smoke collection hood 100, and the rotation drive mechanism is connected to the movable end of the translation drive mechanism. The movable end of the rotation drive mechanism is connected to the bottom of the baffle 200. The rotation drive mechanism drives the baffle 200 to swing in the front-to-back direction so that it switches between the first state and the second state. Its motion state is the same as that in Example 1 and will not be repeated here.

[0067] The difference from Example 1 is that the translation drive mechanism can drive the rotation drive mechanism and the baffle 200 to translate toward or away from the front panel 110 of the smoke hood 100, so that the baffle 200 can fit against the back of the front panel 110, completely sealing the smoke inlet 111 and making the range hood more beautiful. In this way, the baffle 200 can have the following features:

[0068] Closed state, such as Figure 10 As shown, the smoke inlet 111 is completely closed;

[0069] The first state, such as Figure 11 As shown, the baffle 200 is located at the rear side of the smoke inlet 111 and forms an annular first smoke inlet channel 130;

[0070] The second state, such as Figure 12 As shown, the baffle 200 rotates to the maximum angle toward the rear side, the partition structure abuts against the rear panel 120, and the smoke inlet 111 is opened to the maximum.

[0071] Example 3

[0072] like Figure 13 and Figure 14 As shown, different from the form of the filter 520 in Example 1, the filter 520 in this embodiment can be arc-shaped and cooperate with the scraper 800 on the baffle 200 to achieve daily automatic cleaning of the filter 520 when the baffle 200 switches states.

[0073] Specifically, an oil scraping assembly is provided on the back of the baffle 200, and the oil scraping assembly includes a scraper 800 arranged at a distance from the baffle 200. The scraper 800 is connected to the back of the baffle 200 through two connecting arms arranged on the left and right, and the top of the scraper 800 is slightly higher than the upper edge of the baffle 200.

[0074] When the baffle 200 switches from the first state to the second state, the surface that the top of the scraper 800 passes through is consistent with the shape of the bottom surface of the filter 520, so that the top of the scraper 800 abuts the bottom surface of the filter 520 during the state switching process. For the baffle 200 that swings back and forth, the bottom surface of the filter 520 is arc-shaped, and the material of the scraper 800 can be an elastic material, such as silicone. The scraper 800 always abuts the arc-shaped filter 520 above it. During the back and forth swinging process, the scraper 800 can scrape off the oil stains on the bottom surface of the filter 520. When the oil stains on the scraper 800 accumulate to a certain extent, they will fall on the back of the baffle 200 and enter the oil cup 700.

[0075] As the baffle 200 swings forward, oil gradually accumulates in front of the scraper 800, forming a second oil-guiding gap 900 between the scraper 800 and the back of the baffle 200. The oil accumulated in front of the scraper 800 falls through the second oil-guiding gap 900 onto the back of the baffle 200. It should be noted that when the baffle 200 is in the second position, supported by the partition structure, the scraper 800 is spaced apart from the rear panel 120. In other words, the scraper 800 does not directly contact the rear panel 120, and thus does not affect the downward flow of oil on the rear panel into the oil cup 700.

[0076] The range hood provided by the present invention includes the above-mentioned smoke collecting structure. Since the range hood provided by the present invention adopts the above-mentioned smoke collecting structure, the range hood provided by the present invention also has the advantages of the smoke collecting structure.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
