Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to a smoke collecting mechanism and a range hood having the same. Background Art

[0002] At present, the range hoods on the market that promote the selling points of partitioned air intake or smoking generally have two or more air inlets. By partitioning the smoke collecting hood with a filter screen or a condensation plate, a multi-faceted air intake form is formed. However, after the number of air inlets increases, the following deficiencies will occur:

[0003] 1. The noise generated when the air cabinet inside the range hood body operates will radiate out from the air inlet, disturbing the user;

[0004] 2. The droplets inside the cabinet are easy to drip through the air inlet and directly drip onto the stove top, affecting the user experience;

[0005] 3. During the cooking process, when the amount of oil fume generated on both sides of the cooker is uneven, that is, the oil fume on one working station is large and the oil fume on the other side is small, the air volume cannot be accurately distributed to the two air inlets on both sides, resulting in the inability to quickly exhaust the oil fume on the side with large oil fume, and ultimately resulting in oil fume overflow. Summary of the Invention

[0042] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific implementation manners of the present invention or making equivalent substitutions for some technical features without departing from the spirit of the present invention's solution shall be covered within the scope of the technical solution claimed by the present invention.

[0043] Example 1

[0044] Reference Figure 1 and Figure 6 In this embodiment, a smoke collecting mechanism is provided, which is applied to a range hood. The smoke collecting mechanism includes a smoke collecting component 1, a driving component 2, a lever component 3, and a reset component 4. The smoke collecting component 1 is used to prevent oil fume from escaping from the side of the range hood. The driving component 2 is used to provide a power source. One end of the lever component 3 is connected to the driving component 2, and the other end is located near the smoke collecting component 1. The driving component 2 can drive the lever component 3 to flip in the opening direction or the reset direction. When the lever component 3 moves in the opening direction, it can push the smoke collecting component 1 to move in the opening direction, so that the smoke collecting component 1 extends outwards to block the oil fume from escaping from the side of the range hood, thereby facilitating the enhancement of the smoking effect. The reset component 4 is connected to the smoke collecting component 1. When the driving component 2 drives the lever component 3 to flip in the reset direction, the reset component 4 can pull the smoke collecting component 1 to move in the reset direction, so that the smoke collecting component 1 retracts inwards.

[0045] It can be seen that in the smoke collecting mechanism of this embodiment, by connecting one end of the lever component 3 to the driving component 2 and designing the other end near the smoke collecting component 1, and connecting the reset component 4 to the smoke collecting component 1, the structure is simple and occupies a small space. The smoke collecting component 1 can move in the opening direction under the push of the lever component 3 to prevent the oil fume from escaping from the side of the range hood, thereby enhancing the smoking effect. And the smoke collecting component 1 can move in the reset direction under the pull of the reset component 4, so that the smoke collecting component 1 can be hidden inside the range hood.

[0046] Furthermore, the smoke collecting mechanism further includes a sliding component 5, which is slidably connected to the smoke collecting component 1. One end of the reset component 4 is connected to the smoke collecting component 1, and the other end can be designed to be connected to the sliding component 5 or to the inner side of the top of the smoke collecting hood of the range hood. Thus, by slidably connecting the smoke collecting component 1 and the sliding component 5, it effectively ensures that the movement of the smoke collecting component 1 is smoother and prevents the smoke collecting component 1 from getting stuck due to different synchronization on both sides.

[0047] Reference Figure 1-2 In this embodiment, the smoke collecting component 1 includes a smoke collecting plate 11 and a sliding seat 12. The smoke collecting plate 11 is designed below the lever component 3 and is used to prevent the oil fume from escaping from the side of the range hood. The sliding seat 12 is arranged between the smoke collecting plate 11 and the lever component 3 and is fixedly connected to the upper end of the smoke collecting plate 11, while the opposite ends of the sliding seat 12 are respectively slidably connected to the sliding component 5. Thus, through the arrangement of the sliding seat 12, a reliable sliding connection between the smoke collecting plate 11 and the sliding component 5 is achieved.

[0048] The sliding seat 12 is provided with a clamping groove 121 opening towards the smoke collecting plate 11. The clamping groove 121 is clamped on the outer surface of the upper end of the smoke collecting plate 11 and fixedly connected to the smoke collecting plate 11, so that the connection between the smoke collecting plate 11 and the sliding seat 12 is more stable and reliable.

[0049] On one side of the top surface 120 of the sliding seat 12 away from the driving component 2, there is a stop portion 101 extending upwards or obliquely upwards. When the lever component 3 moves towards the opening direction until it abuts against the top surface 120 (i.e., the top of the sliding seat 12), the end of the lever component 3 abutting against the top surface 120 is located between the stop portion 101 and the top of the smoke collecting plate 11. At this time, the stop portion 101 and the top surface 120 limit the lever component 3, increasing the contact area between the lever component 3 and the entire sliding seat 12, ensuring that the lever component 3 can reliably push the sliding seat 12 towards the opening direction. Furthermore, the sliding seat 12 synchronously drives the smoke collecting plate 11 towards the opening direction to prevent oil fume from escaping from the side of the range hood and improve the smoking effect of the range hood. In addition, at the middle position of the top surface 120, there is a lug 102 extending upwards, which is used to connect with the reset component 4.

[0050] At opposite ends of the sliding seat 12, there are two flanges 122 extending integrally upwards. On each flange 122, there is one or two connecting portions 123 extending outwards, and the connecting portions 123 are used for sliding connection with the sliding component 5. In this embodiment, taking each flange 122 having two connecting portions 123 as an example, in pairs of two, through two pairs of connecting portions 123, the connection between the sliding seat 12 and the sliding component 5 is made more reliable.

[0051] Reference Figure 1-2 In this embodiment, the driving component 2 includes a biaxial driver 21 and a fixed bracket 22. The biaxial driver 21 is used to be installed inside the smoke collecting hood of the range hood through the fixed bracket 22. One output end of the biaxial driver 21 is connected to the lever component 3 to push the lever component 3 to perform a flipping motion. The other output end of the biaxial driver 21 is used to connect to the condensation plate component of the range hood. Thus, through the two output ends of the biaxial driver 21, the condensation plate component and the smoke collecting component 1 connected to the same driver 21 can move downwards or upwards simultaneously, realizing the linkage between the condensation plate component and the smoke collecting component 1, and the production cost is lower.

[0052] In other embodiments, two single-axis drivers can be used to replace the biaxial driver 21 in this embodiment. The output end of one single-axis driver is used to connect to the lever component 3, and the output end of the other single-axis driver is used to connect to the condensation plate component of the range hood.

[0053] Reference Figure 3 and Figure 6, in this embodiment, the lever assembly 3 includes a lever 31 and a cam 32. The opposite ends of the lever 31 are respectively connected to the output end of the driver of the drive assembly 2 and the cam 32. The cam 32 is located above the slide 12 of the smoke collecting assembly 1, and when the cam 32 moves towards the slide 12, it can push the smoke collecting assembly 1 towards the open direction. Thus, the drive assembly 2 realizes pushing the smoke collecting assembly 1 towards the open direction through the connected lever 31 and cam 32. Compared with mechanical transmission methods such as gear transmission, turbine and worm transmission, or crank and connecting rod transmission, the overall structure of the lever assembly 3 in this embodiment is simpler, occupies less space, and has lower production costs.

[0054] The lever 31 is provided with a connection hole 211 opening towards the double-shaft driver 21. The output end of the double-shaft driver 21 facing the lever 31 is inserted into the connection hole 211 and fixedly connected to the lever 31. The cam 32 and the lever 31 are connected in an "L" shape. They can be integrally formed or fixedly connected by welding or other means. A flat position hole is provided inside the cam 32 to reduce the weight of the cam 32 itself and ensure that the lever 31 can more easily drive the cam 32 to perform a flipping motion. When the cam 32 rotates towards the open direction until it abuts against the top surface 120 of the slide 12, the cam 32 is located between the stop portion 101 and the top surface 120.

[0055] Reference Figure 1 , in this embodiment, the reset assembly 4 is preferably an elastic member 41. One end of the elastic member 41 is connected to the lug 102 of the smoke collecting assembly 1, and the other end is connected to the sliding assembly 5. Thus, when the smoke collecting assembly 1 moves towards the open direction, it synchronously drives the elastic member 41 to move downward, causing the elastic member 41 to deform and increase. When the smoke collecting assembly 1 moves to the fully open state, the lever assembly 3 tightly abuts against the top of the smoke collecting assembly 1. At this time, the restoring force of the elastic member 41 cannot overcome the downward thrust of the lever assembly 3 on the smoke collecting assembly 1, and the smoke collecting assembly 1 remains in the fully open state. See Figure 7 . When the lever assembly 3 is driven to move in the reset direction, the abutting relationship between the lever assembly 3 and the smoke collecting assembly 1 is released. Under the action of the restoring force of the elastic member 41, the smoke collecting assembly 1 is pulled to move in the reset direction, so that the smoke collecting assembly 1 retracts into the inside of the smoke collecting hood. See Figure 6 .

[0056] In other embodiments, the end of the elastic member 41 far from the smoke collecting assembly 1 can also be designed to be connected to the inner side of the top of the smoke collecting hood of the range hood.

[0057] Reference Figure 4, in a modified embodiment of the reset assembly 4, the reset assembly 4 may be changed to include a reset driver 42, a winding disc 43, and a traction member 44. One end of the traction member 44 is connected to the lug 102 of the smoke collecting assembly 1, and the other end is wound around the winding disc 43. Both the reset driver 42 and the winding disc 43 are adapted to be installed inside the smoke collecting hood of the range hood. The output end of the reset driver 42 is connected to the winding disc 43, and is at least used to drive the winding disc 43 to take in the line when the smoke collecting assembly 1 moves in the reset direction. Of course, it can also be designed to be further used to drive the winding disc 43 to pay out the line when the smoke collecting assembly 1 moves in the opening direction. Thus, by taking in or paying out the line of the winding disc 43, it is ensured that the traction member 44 not only does not hinder the opening of the smoke collecting assembly 1, but also pulls the smoke collecting assembly 1 to perform a reset movement when the smoke collecting assembly 1 needs to be reset.

[0058] Reference Figure 1 and Figure 5-6 , in this embodiment, the sliding assembly 5 includes a slide rail bracket 51 and at least two pulleys 52. The slide rail bracket 51 has two guide rods 511 arranged side by side. The two guide rods 511 are located on the opposite outer sides of the smoke collecting assembly 1. At least one chute 501 arranged in the height direction is provided on each guide rod 511. The number of pulleys 52 corresponds to the number of chutes 501 one by one. Each pulley 52 is rotatably connected to the connecting portion 123 of the sliding seat 12, and each pulley 52 is slidably connected to the corresponding chute 501. Thus, through the cooperation of the chute 501 and the pulley 52, compared with the inner and outer slide rails, the sliding assembly 5 of this embodiment occupies less space, ensures that the sliding assembly 5 can be completely hidden inside the smoke collecting hood, improves the aesthetics, and at the same time can prevent the smoke collecting assembly 1 from jamming due to non-synchronization on both sides.

[0059] In this embodiment, the opposite ends of the sliding seat 12 respectively have a pair of connecting portions 123, and a freely rotatable pulley 52 is installed on each connecting portion 123. Each guide rod 511 is arranged in the middle of a pair of connecting portions 123. Each guide rod 511 has a vertically arranged chute 501 on one side of the corresponding connecting portion 123, and each chute 501 is slidably connected to the corresponding pulley 52. Thus, through the cooperation of two pairs of pulleys 52 and two guide rods 511, the movement of the smoke collecting assembly 1 is more flexible and smoother.

[0060] The guide rod 511 includes a vertical section and a horizontal section connected into a "7" shape. Two chutes 501 arranged oppositely are provided on the vertical section of the guide rod 511. A limiting portion 502 is provided at the upper end and / or the lower end of the corresponding chute 501 on the vertical section. The limiting portion 502 is used to prevent the pulley 52 from disengaging from the chute 501. An installation plate 503 is provided at one end of the horizontal section away from the vertical section. The installation plate 503 is used to be firmly connected to the side wall of the smoke collecting hood. Through the installation plate 503, the installation of the guide rod 511 is facilitated, and the connection strength between the guide rod 511 and the smoke collecting hood is ensured.

[0061] refer to Figure 5-6 In this embodiment, the slide rail bracket 51 also has a connecting rod 512, the opposite ends of which are respectively connected to the upper ends of the two guide rods 511, and a hook 504 is provided in the middle of the connecting rod 512. One end of the elastic member 41 is connected to the lug 102 at the top of the smoke collecting assembly 1, and the other end is connected to the hook 504. Thus, the two guide rods 511 are connected into one body through the connecting rod 512, which is not only convenient for disassembly and transportation, but also effectively strengthens the overall strength of the slide rail bracket 51, and the connecting rod 512 plays the role of receiving and connecting the elastic member 41.

[0062] Example 2

[0063] refer to Figure 6-9 A range hood of this embodiment includes a smoke collecting hood 6 and the smoke collecting mechanism as described in Example 1. The bottom of the smoke collecting hood 6 is provided with an air inlet 601 for oil smoke to pass through, and a channel 602 located outside the air inlet 601, and the channel 602 connects the inside and outside of the smoke collecting hood 6. The bottom of the smoke collecting hood 6 of this embodiment has two air inlets 601 arranged side by side on the left and right and two channels 602 arranged side by side on the left and right. The two air inlets 601 correspond to the smoke sources of the double stoves of the stove to realize double-cavity double suction. The two channels 602 are respectively located on the left and right outer sides of the two air inlets 601, and each channel 602 is used for the smoke collecting plate assembly 1 of the smoke collecting mechanism to move through.

[0064] The number of smoke collecting mechanisms is two. The two smoke collecting mechanisms are respectively installed on the left and right sides of the inside of the smoke collecting hood 6, the bottom of the slide rail bracket 51 abuts against the edge of the corresponding channel 602, and the mounting plate 503 of the slide rail bracket 51 is tightly connected to the side wall of the smoke collecting hood close to it, so as to ensure that the slide rail bracket 51 is firmly and reliably installed inside the smoke collecting hood 6, thereby ensuring that the rest of the smoke collecting mechanism is also reliably installed inside the smoke collecting hood. The smoke collecting plate assembly 1 of each smoke collecting mechanism can move through the corresponding channel 602, and when each smoke collecting assembly 1 is pushed to move in the opening direction, the smoke collecting plate 11 assembly can pass through the channel 602 and extend out of the smoke collecting hood 6 to prevent oil smoke from escaping from the outside of the smoke collecting hood 6, or when the smoke collecting assembly 1 is pulled to move in the resetting direction, the smoke collecting plate 11 assembly can pass through the channel 602 and retract into the smoke collecting hood 6.

[0065] It can be seen that by adding two smoke collecting mechanisms inside the smoke collecting hood 6, the smoke collecting component 1 of each smoke collecting mechanism can move between extending out of the smoke collecting hood 6 and retracting into the smoke collecting hood 6. The smoke collecting mechanism of this embodiment has a simple structure and occupies a small space. According to the situation of oil smoke generation, one or two smoke collecting components 1 can be driven to extend out of the smoke collecting hood 6 to expand the negative pressure area outward, thereby preventing oil smoke from escaping from the outside of the smoke collecting hood 6, thereby significantly improving the smoke collecting effect.

[0066] Further, the range hood further includes a condensate plate assembly 7. The condensate plate assembly 7 is movably disposed below each air inlet portion 601 and is used to open or close the corresponding air inlet portion 601. In this embodiment, when the condensate plate assembly 7 is in the closed state, it can completely close the air inlet portion 601 or not completely close the air inlet portion 601, that is, there is a minimum gap for the flue gas to pass between the edge of the condensate plate assembly 7 and the air inlet portion 601. Thus, the setting of the condensate plate assembly 7, on the one hand, prevents the liquid drops inside the range hood from dripping through the air inlet 102 directly onto the cooking surface, and on the other hand, through logical control of the opening or closing of the two condensate plate assemblies 7 according to the oil fume generation situation, to match the oil fume sizes in different orientations to achieve intelligent smoke extraction, and by adjusting the opening degree of each condensate plate assembly 7, the smoke inlet resistance is reduced and the noise of the air inlet portion 601 is lowered.

[0067] Reference Figure 9 , in this embodiment, the opening of each condensate plate assembly 7 and the smoke collecting assembly 1 on its same side adopt the same power source so that the two move simultaneously. The double-axis driver 21 has two relatively arranged output ends. The double-axis driver 21 is installed inside the smoke collecting hood 6, and one output end of the double-axis driver 21 is connected to the lever assembly 3 of the smoke collecting mechanism, and the other output end is connected to the front side of the condensate plate assembly 7 through the swing arm assembly 8, while the rear side of the condensate plate assembly 7 is hinged or slidably connected to the smoke collecting hood 6. Thus, through the same double-axis driver 21, the condensate plate assembly 7 is connected to the smoke collecting mechanism, ensuring that when the range hood drives the smoke collecting assembly 1 to extend out of the smoke collecting hood 6, the condensate plate assembly 7 on the same side is synchronously driven to open downward, realizing an increase in the unit smoke inlet area while preventing the oil fume from escaping from the side, and significantly improving the smoke collecting effect.

[0068] The smoke extraction machine can perform logical control on the two smoke collecting assemblies 1 and the two condensate plate assemblies 7 according to the oil fume generation situation. The specific control logic is as follows:

[0069] When only the left side or the right side needs to extract smoke, in this embodiment, it is taken as an example that the left side needs to extract smoke. Reference Figure 7-9 and Figure 11 , the left double-axis driver 21 pushes the left condensate plate assembly 7 to flip downward through the swing arm assembly 8 to open the air inlet portion 601. At the same time, the left double-axis driver 21 drives the left lever assembly 3 to flip and move in the opening direction. When the left lever assembly 3 moves in the opening direction, it pushes the left smoke collecting assembly 1 to move in the opening direction, so that the left smoke collecting assembly 1 extends out through the corresponding channel 602, that is, extends out of the smoke collecting hood 6, to block the oil fume from escaping from the side and enhance the smoke extraction effect.

[0070] Reference Figure 6 , Figure 9 and Figure 10, when it is necessary to close the left air inlet part 601, the left double-axis driver 21 drives the left condensing plate assembly 7 to turn upwards through the swing arm assembly 8 to close the air inlet part 601. At the same time, when the left lever assembly 3 is driven to move in the reset direction, under the restoring force of the left elastic member 41, the left smoke gathering assembly 1 is pulled to move in the reset direction, so that the left smoke gathering assembly 1 retracts into the smoke collecting hood.

[0071] When only the left and right sides need to smoke, the movement modes of the smoke gathering assemblies 1 and the condensing plate assemblies 7 on both sides refer to the movement modes of a single side.

[0072] In other embodiments, two single-axis drivers can be used to replace the double-axis driver 21, so that the opening of the condensing plate assembly 7 and the power source of the smoke gathering assembly 1 on the same side are different. At this time, the output end of one single-axis driver is connected to the lever assembly 3, and the output end of the other single-axis driver is connected to the condensing plate assembly 7. Thus, the condensing plate assembly 7 can be independently controlled to be opened or closed according to the generation of oil fume, and the smoke gathering assembly 1 on the same side or the two smoke gathering assemblies 1 can be determined whether to open according to the size of the oil fume concentration, that is, the condensing plate assembly 7 and the condensing plate assembly 7 on the same side can be synchronized or asynchronous.

[0073] Embodiment 3

[0074] The difference between this embodiment and Embodiment 2 is that the numbers of the air inlet part 601 and the condensing plate assembly 7 are different. In this embodiment, only one air inlet part 601 for oil fume to pass through is provided at the bottom of the smoke collecting hood 6, and a switchable condensing plate assembly 7 is provided below the air inlet part 601. When the condensing plate assembly 7 is in the closed state, it can completely close the air inlet part 601 or not completely close the air inlet part 601.

[0075] Smoke gathering mechanisms are respectively provided on the left and right sides inside the smoke collecting hood 6. The smoke gathering assembly 1 of each smoke gathering mechanism can move between extending out of the smoke collecting hood 6 and retracting into the smoke collecting hood 6, and each smoke gathering mechanism is not linked with the condensing plate assembly 7, that is, the power source of the condensing plate assembly 7 is different from the power source for opening the smoke gathering assembly 1. At this time, the condensing plate assembly 7 can be independently controlled to be opened or closed according to the generation of oil fume, and the smoke gathering assemblies 1 on both sides can also be determined whether to open respectively according to the generation position of the oil fume and the size of the oil fume concentration.

[0076] When the oil fume concentration on one side is large and no oil fume is generated on the other side, the smoke gathering assembly 1 on the side with a large oil fume concentration can be controlled to extend out of the smoke collector 6, or the two smoke gathering assemblies 1 can be controlled to extend out of the smoke collecting hood 6. When the oil fume concentrations on both sides are large, the two smoke gathering assemblies 1 are controlled to extend out of the smoke collecting hood 6 to block the escape of oil fume from the side and enhance the smoke absorption effect.

[0077] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
