Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to an oil net component and an integrated stove. Background Art

[0002] Integrated stoves are essential appliances for modern home life. They can discharge the fumes and harmful gases generated during cooking, clean the kitchen environment, and enhance the cooking experience. Existing integrated stoves are all equipped with an oil net assembly, which includes an oil net. When the fumes pass through the oil net, they will contact the oil net, so that part of the heat of the fumes is absorbed by the oil net, and then the fumes are condensed and filtered by the oil net, achieving the effect of oil separation and reducing the amount of fumes discharged.

[0003] In order to ensure the oil net's effect of separating grease, in the prior art, multiple oil nets are arranged at intervals in the smoking chamber. However, while the oil nets separate grease, they also hinder the passage of oil fume airflow. In order to take into account the efficiency of oil fume extraction, in the prior art, multiple oil nets are rotatably arranged in the cavity of the smoking chamber. During the cooking process, the multiple oil nets are synchronously rotated to a suitable angle according to the requirements of oil fume extraction efficiency. However, the rotation of the oil net in the smoking chamber will cause the distance between the periphery of the oil net and the cavity of the smoking chamber to change. Specifically, the distance between the periphery of the oil net and the cavity of the smoking chamber increases with the increase of the hood gear, which will result in the higher the fan gear, the worse the filtering effect of the oil net assembly on oil fume will be.

Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0053] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0055] This embodiment provides an integrated range hood, which can be applied to dining places such as kitchens and hotels. The integrated range hood can integrate multiple functions such as a smoke machine, a cooker, a disinfection cabinet, and a steam oven.

[0056] Please refer to Figures 1 to 4 , the integrated range hood includes a body 10, a machine head 20, an air box 30, a fan 40, a burner 50, and an oil screen assembly 60. The burner 50 and the machine head 20 are both arranged above the body 10. The air box 30 is arranged inside the body 10, and the fan 40 is arranged inside the air box 30. The oil screen assembly 60 includes a plurality of oil screens and a smoke collecting cavity 4. The smoke collecting cavity 4 includes a first direction (such as Figure 2A first smoking channel 41, an intermediate smoking channel 42, and a second smoking channel 43 that are connected in sequence in the direction indicated by arrow ab. The first smoking channel 41 is disposed within the machine head 20. The machine head 20 is further provided with a smoke inlet 44 that communicates with the first smoking channel 41. The intermediate smoking channel 42 and the second smoking channel 43 are both disposed within the air box 30. A plurality of oil meshes are disposed within the intermediate smoking channel 42. Among them, the burner 50 is used to heat the cooking appliance, and thus the cooking appliance can be used to cook food materials. The oil fume generated during the cooking process, under the negative pressure provided by the blower 40, enters the first smoking channel 41 through the smoke inlet 44, then enters the air box 30 and successively passes through the intermediate smoking channel 42 and the second smoking channel 43, and is discharged from the integrated stove through the blower 40. When the oil fume passes through the intermediate smoking channel 42, part of the heat of the oil fume is absorbed by the plurality of oil meshes, and thus the oil fume is condensed and filtered by the plurality of oil meshes, achieving the effect of oil-gas separation and reducing the amount of discharged oil fume.

[0057] Optionally, the machine body 10 is further provided with a smoke exhaust port 101. Under the drive of the blower 40, the oil fume is discharged from the smoke exhaust port 101 out of the machine body 10. Among them, the output end of the blower 40 and the smoke exhaust port 101 can be connected through a corrugated pipe, or the output end of the blower 40 partially extends out of the machine body 10 through the smoke exhaust port 101.

[0058] Optionally, the integrated stove further includes a knob 80 disposed on the machine body 10. The knob 80 is used to control the fire power of the burner 50. It should be noted that the number of burners 50 can be set according to actual needs. For example, it can be set to one, two, or three, etc. Correspondingly, the number of knobs 80 is set to be the same as the number of burners 50, and the two are set in one-to-one correspondence.

[0059] Optionally, the integrated stove further includes a gas inlet interface 90 disposed on the machine body 10. The gas inlet interface 90 is used to communicate with a gas supply pipeline and supply gas to the burner 50.

[0060] Optionally, the integrated stove further includes feet 100 disposed below the machine body 10, and a kick plate 110 disposed below the machine body 10 and at the front end of the machine body 10. The integrated stove is supported on the ground by the feet 100, and the rear feet 100 are shielded by the kick plate 110 to keep the integrated stove beautiful.

[0061] Optionally, the integrated stove further includes a steam oven 120 integrated into the machine body 10, and a control panel 70 disposed on the machine body 10. The control panel 70 is used to control the steam oven 120. In other embodiments, the steam oven 120 can also be replaced with a disinfection cabinet, an oven, a steamer, etc.

[0062] Optionally, the integrated stove further includes an oil collecting box 130 disposed at the bottom of the machine body 10, and the oil collecting box 130 is used to collect the oil liquid collected in the steam oven 120 and the air box 30.

[0063] Optionally, please refer to Figures 2 to 8 , in this embodiment, the oil mesh assembly 60 specifically includes two oil meshes, which are the first oil mesh 1 and the second oil mesh 2 respectively. The first oil mesh 1 and the second oil mesh 2 are arranged at intervals in the first direction, and both the first oil mesh 1 and the second oil mesh 2 are arranged in the middle smoke suction channel 42. When the oil fume passes through the middle smoke suction channel 42, the oil fume first passes through the first oil mesh 1 and then through the second oil mesh 2. The oil fume can contact the first oil mesh 1 and the second oil mesh 2 respectively, so that the oil fume can be fully cooled and the effect of oil fume separation can be improved. In other embodiments, the oil mesh assembly 60 can also include multiple first oil meshes 1 and one second oil mesh 2 as needed. Among them, the multiple first oil meshes 1 and one second oil mesh 2 are arranged at intervals in sequence in the first direction.

[0064] It should be noted that in this embodiment, the oil mesh assembly 60 is not limited to being applied to the integrated stove. In other embodiments, the oil mesh assembly 60 can also be applied to a top suction range hood, a side suction range hood, etc.

[0065] Optionally, in this embodiment, the first direction is specifically the vertical direction, that is, the first smoke suction channel 41, the middle smoke suction channel 42, and the second smoke suction channel 43 all extend in the vertical direction. The second oil mesh 2 is located below the first oil mesh 1, so that the grease separated by the first oil mesh 1 and the second oil mesh 2 can directly drip downward into the air box 30. Preferably, both the first oil mesh 1 and the second oil mesh 2 are arranged at an angle with the horizontal plane, which helps the grease collected on the first oil mesh 1 and the second oil mesh 2 to smoothly drip into the air box 30. In other embodiments, the extending directions of the first smoke suction channel 41, the middle smoke suction channel 42, and the second smoke suction channel 43 can also be set according to actual needs.

[0066] Optionally, the outer periphery of the first oil mesh 1 fits with the inner wall of the middle smoke suction channel 42. With this setting, it is ensured that all the oil fume entering the middle smoke suction channel 42 needs to pass through the first oil mesh 1 to further ensure the stable filtering effect of the oil mesh assembly 60 on the oil fume.

[0067] Optionally, the outer periphery of the second oil mesh 2 is in clearance fit with the inner wall of the smoke suction channel. When the oil fume passes through the first oil mesh 1, it directly blows towards the second oil mesh 2. A part of the oil fume can directly pass through the second oil mesh 2, and another part can also flow downward through the gap between the second oil mesh 2 and the inner wall of the second smoke suction channel 43, which can effectively reduce the wind resistance of the oil mesh assembly 60 and increase the air volume passing through per unit time.

[0068] In the prior art, multiple oil nets are rotatably arranged in the smoking channel. During the cooking process, the multiple oil nets are synchronously rotated to a suitable angle according to the demand for oil fume suction efficiency. This will cause the distance between the outer periphery of the oil net and the channel wall of the smoking channel to change as the oil net rotates in the smoking channel. Specifically, the distance between the outer periphery of the oil net and the channel wall of the smoking channel increases as the range hood gear is increased. Therefore, the higher the fan gear is, the worse the filtering effect of the oil net assembly on oil fume will be.

[0069] For this, please refer to Figures 2 to 7 In this embodiment, the center line of the middle smoking channel 42 and the center line of the second smoking channel 43 are along the second direction (eg Figure 2 The first and second directions are arranged at intervals (in the direction indicated by the arrow cd in the middle), and the first direction is perpendicular to the second direction; the first oil net 1 is fixedly arranged in the middle smoking channel 42; the second oil net 2 is arranged at intervals with the first oil net 1 along the first direction, and the second oil net 2 is rotatably connected to the inner wall of the middle smoking channel 42 through the rotating shaft 25, and the rotating shaft 25 is centrally arranged in the middle smoking channel 42 along the second direction; the driving mechanism 3 is transmission-connected to the second oil net 2, and the driving mechanism 3 can drive the second oil net 2 to rotate around the axis of the rotating shaft 25. With such arrangement, the angle of the second oil net 2 relative to the first oil net 1 can be adjusted by rotating the second oil net 2, so that the oil smoke has different moving paths when passing through the first oil net 1 and the second oil net 2, and thus has different wind resistances, so as to adapt to the requirements of different cooking conditions for oil fume suction efficiency; in addition, the position of the first oil net 1 relative to the smoking channel remains unchanged, so that the oil fume can all pass through the first oil net 1, and most of the oil fume can also pass through the second oil net 2, thereby ensuring that the oil net assembly 60 can always filter the oil fume stably, thereby achieving a balance between the oil fume suction efficiency and the oil fume filtering effect under different fan 40 gears.

[0070] Optionally, the rotating shaft 25 is indirectly mounted on the second oil net 2, and the second oil net 2 is rotatably connected to the middle smoking channel 42 via two rotating shafts 25. Specifically, the second oil net 2 is provided with two connecting blocks 24, and the rotating shaft 25 is mounted on both connecting blocks 24. Two limit blocks 27 are fixed to the inner wall of the middle smoking channel 42, and the two rotating shafts 25 are rotatably connected to the two limit blocks 27, respectively, so as to ensure the stability of the rotation of the second rotating shaft 25. In other embodiments, the rotating shaft 25 can also be directly mounted on the second oil net 2.

[0071] The angle of the second oil net 2 relative to the first oil net 1 can be adjusted by rotating the second oil net 2, so that the oil smoke has different moving paths when passing through the first oil net 1 and the second oil net 2, and thus has different wind resistances to meet the requirements of different cooking conditions for oil smoke extraction efficiency. The principle is as follows:

[0072] On the one hand, if Figure 4As shown, the center line of the middle smoke extraction channel 42 is L1, and the center line of the second smoke extraction channel 43 is L2. L1 and L2 are arranged at intervals along the second direction. Therefore, during the process that the oil fume passes through the middle smoke extraction channel 42 and enters the second smoke extraction channel 43, the center of the oil fume airflow will shift.

[0073] On the other hand, the first oil screen 1 has a first fixed end 141 and a second fixed end 142 located at both ends in the second direction, and the second oil screen 2 has a first movable end 261 and a second movable end 262 located at both ends in the second direction. L2, the first fixed end 141 and the first movable end 261 are all located on the left side of L1, and the second fixed end 142 and the second movable end 262 are all located on the right side of L1. The driving mechanism 3 can drive the second oil screen 2 to rotate reciprocally so that the second oil screen 2 has a first extreme position, a parallel position and a second extreme position. As Figure 5 shown, when the second oil screen 2 is in the first extreme position, the first oil screen 1 and the second oil screen 2 are arranged at an angle. The distance between the first fixed end 141 and the first movable end 261 is the smallest, and the distance between the second fixed end 142 and the second movable end 262 is the largest. The distance between the first fixed end 141 and the first movable end 261 is less than the distance between the second fixed end 142 and the second movable end 262, that is, it is narrower between the first fixed end 141 and the first movable end 261, and wider between the second fixed end 142 and the second movable end 262, making the air resistance between the first fixed end 141 and the first movable end 261 greater than the air resistance between the second fixed end 142 and the second movable end 262. After the oil fume passes through the first oil screen 1, most of the oil fume will enter the second oil screen 2 between the second fixed end 142 and the second movable end 262, and a small part of the oil fume will enter the second oil screen 2 between the first fixed end 141 and the first movable end 261. Overall, the main movement path of the oil fume between the two oil screens is located on the right side of L1, that is, it needs to bypass the rotating shaft 25. As Figure 6 shown, when the second oil screen 2 is in the parallel position, the first oil screen 1 and the second oil screen 2 are parallel to each other. The distance between the first fixed end 141 and the first movable end 261 is equal to the distance between the second fixed end 142 and the second movable end 262, that is, the air resistance at each part between the first oil screen 1 and the second oil screen 2 is the same. Overall, the main movement path of the oil fume between the two oil screens approximately follows L1. As Figure 7As shown, when the second oil screen 2 is in the second extreme position, the first oil screen 1 and the second oil screen 2 are arranged at an angle. The distance between the first fixed end 141 and the first movable end 261 is the largest, and the distance between the second fixed end 142 and the second movable end 262 is the smallest. The distance between the first fixed end 141 and the first movable end 261 is greater than the distance between the second fixed end 142 and the second movable end 262. That is, it is more open between the first fixed end 141 and the first movable end 261, and more narrow between the second fixed end 142 and the second movable end 262, making the air resistance between the first fixed end 141 and the first movable end 261 less than the air resistance between the second fixed end 142 and the second movable end 262. After the oil fume passes through the first oil screen 1, most of the oil fume will enter the second oil screen 2 between the first fixed end 141 and the first movable end 261, and a small part of the oil fume will enter the second oil screen 2 between the second fixed end 142 and the second movable end 262. Overall, the main movement path of the oil fume between the two oil screens is on the left side of L1 and there is no need to bypass the rotating shaft 25. Therefore, by rotating the second oil screen 2, it is possible to make the oil fume have different lengths of movement paths when passing between the first oil screen 1 and the second oil screen 2.

[0074] Therefore, considering the above two aspects, by adjusting the position of the second oil screen 2, it is possible to make the oil fume have different moving lengths when passing through the middle oil fume suction channel and entering the second oil fume suction channel, and thus have different air resistances, which can meet the suction efficiency requirements of the oil fume under different fan 40 gears.

[0075] Optionally, the center lines of the first smoke suction channel 41 and the middle smoke suction channel 42 are arranged at intervals in the second direction, and in the second direction, the center lines of the first smoke suction channel 41 and the second smoke suction channel 43 are both on the same side of the center line of the middle smoke suction channel 42. Specifically, please refer to Figure 4 , the center line of the first smoke suction channel 41 is L3. Both L2 and L3 are on the left side of L1, and L3 is between L1 and L2. During the process of the oil fume passing from the first smoke suction channel 41 through the middle smoke suction channel 42 and entering the second smoke suction channel 43, the length of the movement path of the oil fume can continuously change with the rotation of the second oil screen 2. Specifically, as the second oil screen 2 rotates from the first extreme position to the second extreme position, the length of the movement path of the oil fume passing from the first smoke suction channel 41 through the middle smoke suction channel 42 and entering the second smoke suction channel 43 gradually becomes smaller.

[0076] Specifically, during the process that the cooking fume passes through the first smoking channel 41, the intermediate smoking channel 42 and enters the second smoking channel 43, when the second oil screen 2 is at the first extreme position, the center of the cooking fume airflow first transfers from L3 to the right side of L1, and then transfers to L2, and the length of the moving path of the cooking fume is the largest; when the second oil screen 2 is at the parallel position, the center of the cooking fume airflow first transfers from L3 to L1, and then transfers to L2, and the length of the moving path of the cooking fume is moderate; when the second oil screen 2 is at the second extreme position, the center of the cooking fume airflow transfers from L3 to the left side of L1 (specifically between L2 and L3 in this embodiment), and then transfers to L2, and the length of the moving path of the cooking fume is the shortest.

[0077] Optionally, when controlling the integrated range hood, when the blower 40 is at a low fan speed, the second oil screen 2 is at the first extreme position, and the length of the moving path of the cooking fume passing through the first smoking channel 41, the intermediate smoking channel 42 and entering the second smoking channel 43 is the largest, and the air intake is tortuous and unsmooth; when the blower 40 is at a high fan speed, the second oil screen 2 is at the parallel position, and the length of the moving path of the cooking fume passing through the first smoking channel 41, the intermediate smoking channel 42 and entering the second smoking channel 43 is moderate, and the air intake is relatively smooth; when the blower 40 is at a stir-fry fan speed, the second oil screen 2 is at the second extreme position, and the length of the moving path of the cooking fume passing through the first smoking channel 41, the intermediate smoking channel 42 and entering the second smoking channel 43 is the shortest, and the air intake is the smoothest, so as to adapt to the air volume requirements at different gears.

The first direction, the second direction, and the third direction are perpendicular to each other in pairs; the first mesh hole 13 has a first input port 131 and a first output port 132 located at both ends in the first direction, and the cross-sectional area of the first mesh hole 13 gradually decreases from the first input port 131 to the first output port 132. With such a setting, when the cooking fume passes through the first oil screen 1, the cooking fume enters the corresponding first mesh hole 13 from each first input port 131 and is discharged from the corresponding first output port 132. Since the cross-sectional area of the first mesh hole 13 gradually decreases from the first input port 131 to the first output port 132, the first mesh hole 13 has a constricted structure, so that the first mesh hole 13 can play a guiding role in the passing cooking fume, enabling the airflow to be guided smoothly when the cooking fume passes through the first oil screen 1, and improving the cooking fume exhaust effect; in addition, the first mesh hole 13 has a constricted structure, which can also enhance the reflection effect of the hole wall of the first mesh hole 13 on sound waves and can effectively reduce noise. In other embodiments, the multiple first mesh holes 13 of the first oil screen 1 can also be arranged in a multi-row and multi-column array.

[0079] It can be understood that along the direction from the first input port 131 to the first output port 132, the cross-sectional area of the first rib 12 gradually increases, so that the cross-sectional area of the first mesh hole 13 between two adjacent first ribs 12 can gradually decrease.

[0080] Optionally, the first rib 12 is provided with a first groove 121, and the opening of the first groove 121 faces the second oil screen 2. With such a setting, when the sound wave is transmitted into the first groove 121, the reflection through the side wall of the first groove 121 can reduce the noise to a certain extent; in addition, the weight of the first rib 12 can also be reduced, which is beneficial to the lightweight design of the whole machine.

Since the cross-sectional area of the second mesh hole 23 gradually decreases from the second input port 231 to the second output port 232, the second mesh hole 23 has a constricted structure, so that the second mesh hole 23 can play a guiding role in the passing cooking fume, enabling the airflow to be guided smoothly when the cooking fume passes through the second oil screen 2, and improving the cooking fume exhaust effect; in addition, the second mesh hole 23 having a constricted structure can also enhance the reflection effect of the hole wall of the second mesh hole 23 on sound waves and effectively reduce noise. In other embodiments, the plurality of second mesh holes 23 of the second oil screen 2 can also be arranged in a multi-row and multi-column array.

[0084] It can be understood that along the direction from the second input port 231 to the second output port 232, the cross-sectional area of the second rib 22 gradually increases, so that the cross-sectional area of the second mesh hole 23 between two adjacent second ribs 22 can gradually decrease.

[0085] Optionally, the second rib 22 is provided with a second groove 221, and the opening direction of the second groove 221 is the same as that of the first groove 121.
