Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a stepped fume extraction system and an integrated stove. Background Art

[0002] At present, with the improvement of people's living standards, the requirements for kitchen appliances are getting higher and higher. In this case, integrated stoves are gradually entering every household as a new kitchen equipment. The integrated stove is to embed the gas stove into the stove, and the range hood is installed on the upper back of the stove. The fan system of the range hood is located below the stove and set in the box, which shortens the distance between the range hood and the stove, thereby improving the range hood's efficiency in absorbing fumes.

[0003] However, existing integrated stoves generally use side suction to absorb oil smoke. When a large amount of oil smoke is generated instantly, part of the oil smoke often escapes at the top, seriously affecting the user experience. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, one of the objects of the present invention is to provide a stepped distributed oil fume extraction system, which can set oil fume extraction ports at different heights on the shell and be used in conjunction with different air ducts to improve the oil fume extraction efficiency.

[0005] The second object of the present invention is to provide an integrated stove, wherein the oil fume suction system on the stove top can be provided with oil fume suction ports at different heights and used in conjunction with different air ducts to improve the oil fume suction efficiency.

[0006] One of the purposes of the present invention is achieved by the following technical solution:

[0008] Furthermore, there are two flues and two oil-intake ports; one of the flues is the first flue and the other is the second flue; one of the oil-intake ports is the first oil-intake port; the other oil-intake port is the second oil-intake port, and the first oil-intake port and the second oil-intake port are spaced apart in the height direction of the shell; the first oil-intake port is connected to the top of the first flue, and a first smoke outlet is provided at the bottom of the second flue, and the first smoke outlet is connected to the main flue; the second oil-intake port is connected to the top of the second flue, and a second smoke outlet is provided at the bottom of the second flue; the adjustment plate is pivotally connected to the main flue, and the adjustment plate can reciprocate between the first smoke outlet and the second smoke outlet.

[0009] Furthermore, the adjustment plate is pivotally connected to the main flue; and the adjustment plate driving member is used to drive the adjustment plate to rotate.

[0010] Furthermore, an oil fume sensor is provided in the first oil fume suction port, and the oil fume sensor is used to detect the amount of oil fume; and the adjustment plate driving member is used to drive the adjustment plate to move according to the amount of oil fume.

[0011] Furthermore, a fan is provided in the main flue, and the fan is used to receive the oil smoke signal to adjust the fan air volume.

[0012] Furthermore, a fume filter is provided at the bottom end of the main flue.

[0013] Furthermore, a first oil guide plate is provided on the bottom side wall of the main flue; the first oil guide plate is gradually inclined inward from top to bottom.

[0014] Furthermore, a second oil guide plate is provided on the bottom side wall of the main flue, and the second oil guide plate is provided on a side of the main flue away from the first oil guide plate, and the first oil guide plate and the second oil guide plate are distributed in sequence at intervals in the height direction of the main flue.

[0016] The second object of the present invention is achieved by adopting the following technical solution:

[0017] The integrated stove comprises a stove top and the stepped-distributed oil fume extraction system; the shell is installed at the rear end of the stove top.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When extracting oil smoke, since the oil smoke intake ports are arranged at different heights on the shell body, when there is less oil smoke, the adjustment plate can be driven by the adjustment plate driving member to face the flue smoke outlet corresponding to the higher position of the oil smoke intake port, that is, the oil smoke intake port used as the main flue is relatively low, and the other flue is used as an auxiliary flue; and when there is more oil smoke, the adjustment plate can be driven by the adjustment plate driving member to face the flue smoke outlet corresponding to the lower position of the oil smoke intake port, that is, the oil smoke intake port used as the main flue is relatively high, and the other flue is used as an auxiliary flue. In this way, different air ducts can be used according to the amount of oil smoke to improve the oil smoke extraction efficiency.

[0019] 2. Each flue is relatively independent, which effectively prevents mutual interference and prevents smoke exhaust from being blocked in the flue, making smoke exhaust smoother. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0026] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Embodiment 1,

[0029] like Figure 1 as well as Figure 2 The ladder-distributed oil fume extraction system shown includes a housing 10, in which a main flue 11, at least two flues, an adjustment plate 16 and an adjustment plate driving member 17 are arranged. In addition, at least two oil fume suction ports are arranged on the housing 10, and the at least two oil fume suction ports are spaced apart in the height direction of the housing 10, and each oil fume suction port is connected to the top of each flue, and a smoke outlet is arranged at the bottom of each flue, and each smoke outlet is connected to the main flue 11. The above-mentioned adjustment plate 16 is arranged in the main flue 11, and the adjustment plate 16 can reciprocate between each smoke outlet, and the adjustment plate driving member 17 can drive the adjustment plate 16 to move.

[0030] On the basis of the above structure, when the stepped distributed oil fume extraction system of the present invention is used, when the oil fume extraction operation is performed, since the oil fume extraction ports are arranged at different heights on the shell 10, when there is less oil fume, the adjustment plate 16 can be driven by the adjustment plate driving member 17 to face the flue smoke outlet corresponding to the higher position of the oil fume extraction port, that is, the oil fume extraction port used as the main flue is relatively low, and the other flue is used as an auxiliary flue; and when there is more oil fume, the adjustment plate 16 can be driven by the adjustment plate driving member 17 to face the flue smoke outlet corresponding to the lower position of the oil fume extraction port, that is, the oil fume extraction port used as the main flue is relatively high, and the other flue is used as an auxiliary flue. In this way, different air ducts can be used according to the amount of oil fume to improve the oil fume extraction efficiency.

[0031] In addition, the above-mentioned flues are relatively independent, which effectively prevents mutual interference and prevents smoke exhaust from being blocked in the flue, making smoke exhaust smoother.

[0032] In the present embodiment, there are two flues and two oil-intake ports, one of which is a first flue 12, the other is a second flue 13, and one of the oil-intake ports is a first oil-intake port 14; the other is a second oil-intake port 15, and the first oil-intake port 14 and the second oil-intake port 15 are spaced apart in the height direction of the shell 10. Specifically, the first oil-intake port 14 can be set at the top of the shell 10, and the second oil-intake port 15 can be set at the side of the shell 10.

[0033] On the basis of the above structure, the first oil suction port 14 is connected with the top of the first flue 12, the bottom end of the second flue 13 is provided with a first smoke outlet, and the first smoke outlet is connected with the main flue 11; the second oil suction port 15 is connected with the top of the second flue 13, and the bottom end of the second flue 13 is provided with a second smoke outlet; the adjustment plate 16 is pivotally connected in the main flue 11, and the adjustment plate 16 can reciprocate between the first smoke outlet and the second smoke outlet; the adjustment plate 16 is used to cover or partially cover the first smoke outlet or the second smoke outlet when moving between the first smoke outlet and the second smoke outlet.

[0034] In this way, when extracting oil smoke, when the oil smoke in the pot is sprayed out at a higher speed or a higher position, if the amount of oil smoke is large, the amount of oil smoke will rise in large quantities, and smoking will be mainly done by inhaling from above. At this time, the adjusting plate driving member 17 can drive the adjusting plate 16 to move close to the smoke outlet of the second flue 13, and the adjusting plate 16 can relatively cover the smoke outlet part of the second flue 13, that is, the first flue 12 is the main flue, and the second flue 13 is the auxiliary flue. The rising oil smoke can be extracted from the first flue 12, and the second flue 13 can assist in extracting the oil smoke from the side.

[0035] When the oil smoke in the pot gushes out at a slower speed or at a lower position, the oil smoke is mainly sucked from the side. At this time, the adjusting plate driving member 17 can drive the adjusting plate 16 to move close to the smoke outlet of the first flue 12, and the adjusting plate 16 can relatively cover the smoke outlet part of the first flue 12. At this time, the first flue 12 is used as an auxiliary flue, and the second flue 13 is the main flue.

[0036] It should be noted that the first oil fume suction port can be used for top smoking, and the second oil fume suction port can be used for side smoking, thereby making up for the insufficient oil fume suction of traditional integrated stoves.

[0037] The regulating plate 16 can be adjusted according to the actual amount of oil smoke, so as to maximize the smoke extraction efficiency and prevent the oil smoke from overflowing.

[0038] It should be noted that the above-mentioned oil fume outlets are provided with two, so there are only one oil fume outlet at the top and one oil fume outlet at the side. In other cases, three or more flues can be provided, and three or more corresponding oil fume suction outlets can also be provided. One oil fume suction outlet is provided at the top, and at least two are provided in the height direction of the side of the shell 10, so that there are more options for the oil fume inlet.

[0039] More specifically, the adjustment plate 16 is pivotally connected to the main flue 11, and the adjustment plate driving member 17 is used to drive the adjustment plate 16 to rotate. In the case where two flues are provided, the adjustment plate 16 can be provided between the smoke outlets of the first flue 12 and the second flue 13, and the adjustment plate driving member 17 can be used to drive the adjustment plate 16 to rotate toward different smoke outlets. When the adjustment plate 16 is rotated to different positions, the opening and closing angles of the smoke outlets of the first flue 12 or the second flue 13 can be adjusted, and the adjustment range is more flexible.

[0040] Of course, when there are multiple flues, an adjustment plate 16 can be provided between two adjacent flues, and the adjustment plate 16 can be rotated between the smoke outlets of the two adjacent flues.

[0041] In addition, the adjustment plate 16 may also be in linear motion, and the adjustment plate 16 may be extended or retracted in the main flue 11 . However, the use of linear motion relative to rotational motion requires a larger movement space, thereby increasing the volume of the shell 10 .

[0042] Furthermore, an oil fume sensor 141 is provided in the first oil fume suction port 14, and the oil fume sensor 141 can detect the amount of oil fume, and the adjustment plate driving member 17 can drive the adjustment plate 16 to move according to the amount of oil fume.

[0043] When the amount of oil smoke in the first flue 12 is small, the adjusting plate driving member 17 can drive the adjusting plate 16 to rotate close to the smoke outlet of the first flue 12, cover the part of the first flue 12, and the second flue 13 can be opened to a greater extent and used as the main flue. When the oil smoke concentration increases significantly, that is, the oil smoke volume of the first flue 12 increases, the adjusting plate driving member 17 can drive the adjusting plate 16 to rotate according to the oil smoke volume, and can move the adjusting plate 16 toward the smoke outlet of the second flue 13, so that the smoke outlet of the first flue 12 can be opened to a greater extent, and the power of the variable frequency fan is automatically increased, and the first flue 12 can discharge a larger amount of oil smoke.

[0044] When the oil fume concentration exceeds the limit value of the oil fume sensor, the adjustment plate driving part 17 can drive the adjustment plate 16 to rotate close to the smoke outlet of the second flue 13 and completely cover the second flue. The smoke outlet of the first flue 12 is opened to the maximum value. At this time, the air suction volume of the first flue 12 is equal to that of the main flue 11. At the same time, the power of the variable frequency fan is automatically adjusted to the maximum value to discharge the oil fume to the greatest extent.

[0045] Furthermore, a fan may be provided in the main flue 11, and the fan is used to receive the oil fume signal. In the present embodiment, the fan may be a variable frequency fan in the prior art. When the amount of oil fume is large, the variable frequency fan may adjust the frequency of the fan according to the oil fume signal detected by the oil fume sensor 141, thereby increasing the speed, increasing the wind pressure, and enhancing the suction force to ensure that no smoke is missed. When the oil fume concentration is significantly reduced, the speed of the variable frequency fan is reduced, and the wind pressure is automatically reduced, thereby effectively saving energy and reducing noise. In this way, maximum energy saving can be achieved.

[0046] Of course, a control panel and a controller may be provided at the top of the shell 10. The control panel may receive the detection result of the oil fume sensor 141, and then the controller may control the variable frequency fan and the adjusting plate driving member 17 in a timely manner according to the detection structure.

[0047] Furthermore, an oil fume filter 18 is provided at the bottom end of the main flue, that is, after the oil fume is discharged from multiple flues to the main flue, the oil fume can be filtered through the oil fume filter 18, and the oil in the oil fume can be filtered out through the oil fume filter 18, so that the smoke discharged from the smoke-oil system is more environmentally friendly and reduces the oil fume adhering to the outlet.

[0048] Furthermore, a first oil guide plate 111 is provided on the bottom side wall of the main flue 11, and the first oil guide plate 111 is gradually inclined inward from top to bottom, so that the first oil guide plate 111 can block the oil in the main flue 11 and guide the oil droplets to be discharged downward through the outlet.

[0049] More specifically, a second oil guide plate 112 may be provided on the bottom side wall of the main flue 11. The second oil guide plate 112 is provided on a side of the main flue 11 away from the first oil guide plate 111. The first oil guide plate 111 and the second oil guide plate 112 are spaced apart in sequence in the height direction of the main flue 11. The second oil guide plate 112 can pour oil on the opposite side of the first oil guide plate 111. The first oil guide plate 111 and the second oil guide plate 112 can guide oil droplets out in different directions and guide the oil centrally, which is convenient for centralized cleaning later.

[0050] Furthermore, the shell 10 in this embodiment includes a first panel 20, a second panel 30 and two side panels 40, and the first panel 20 and the second panel 30 are arranged at intervals; the two side panels 40 are respectively connected to the two sides of the first panel 20 and the second panel 30, so that a smoking space can be enclosed by the first panel 20, the second panel 30 and the two side panels 40, and partitions are arranged in the first panel 20 and the second panel 30 to separate them into a flue. In this way, a flue can be formed by simply assembling different panels through a screw structure, which is convenient for disassembly and cleaning and easy to process.

[0051] In addition, the top of the first panel 20 is bent toward the second panel 30 to form a bent plate 21, and the bent plate 21 can be spaced apart from the top of the second panel 30. The bent plate 21 is provided with an oil smoke suction port, and the bent plate 21 can block the rising oil smoke and guide it out through the oil smoke suction port on the bent plate 21. In addition, the top of the second panel 30 and the partition plate provided between the first panel 20 and the second panel 30 can also be spaced apart to form an oil smoke suction port, without the need for an additional opening on the second panel 30, and the processing is also convenient.

[0052] Embodiment 2,

[0053] like Figure 1-4 The integrated stove shown includes a stove top 60 and the stepped fume extraction system in Example 1, and the housing 10 is installed at the rear end of the stove top 60 .

[0054] In this way, when cooking is performed, the stove on the stove table 60 can heat the pot and cook, and the generated oil smoke can be extracted through the oil smoke extraction system.

[0055] Specifically, the stepped distributed oil fume extraction system includes a housing 10, in which a main flue 11, at least two flues, an adjustment plate 16 and an adjustment plate driving member 17 are arranged. In addition, at least two oil fume extraction ports are arranged on the housing 10, and the at least two oil fume extraction ports are spaced apart in the height direction of the housing 10, and each oil fume extraction port is connected to the top of each flue, and a smoke outlet is arranged at the bottom of each flue, and each smoke outlet is connected to the main flue 11. The adjustment plate 16 is arranged in the main flue 11, and the adjustment plate 16 can reciprocate between each smoke outlet, and the adjustment plate driving member 17 can drive the adjustment plate 16 to move.

[0056] When extracting oil fume, since the oil fume intake ports are arranged at different heights on the shell 10, when there is less oil fume, the adjustment plate 16 can be driven by the adjustment plate driving member 17 to face the flue smoke outlet corresponding to the higher position of the oil fume intake port, that is, the oil fume intake port used as the main flue is relatively low, and the other flue is used as an auxiliary flue; and when there is more oil fume, the adjustment plate 16 can be driven by the adjustment plate driving member 17 to face the flue smoke outlet corresponding to the lower position of the oil fume intake port, that is, the oil fume intake port used as the main flue is relatively high, and the other flue is used as an auxiliary flue. In this way, different air ducts can be used according to the amount of oil fume to improve the oil fume extraction efficiency.

[0057] In addition, the above-mentioned flues are relatively independent, which effectively prevents mutual interference and prevents smoke exhaust from being blocked in the flue, making smoke exhaust smoother.

[0058] In the present embodiment, there are two flues and two oil-intake ports, one of which is a first flue 12, the other is a second flue 13, and one of the oil-intake ports is a first oil-intake port 14; the other is a second oil-intake port 15, and the first oil-intake port 14 and the second oil-intake port 15 are spaced apart in the height direction of the shell 10. Specifically, the first oil-intake port 14 can be set at the top of the shell 10, and the second oil-intake port 15 can be set at the side of the shell 10.

[0059] On the basis of the above structure, the first oil suction port 14 is connected with the top of the first flue 12, the bottom end of the second flue 13 is provided with a first smoke outlet, and the first smoke outlet is connected with the main flue 11; the second oil suction port 15 is connected with the top of the second flue 13, and the bottom end of the second flue 13 is provided with a second smoke outlet; the adjustment plate 16 is pivotally connected in the main flue 11, and the adjustment plate 16 can reciprocate between the first smoke outlet and the second smoke outlet; the adjustment plate 16 is used to cover or partially cover the first smoke outlet or the second smoke outlet after moving between the first smoke outlet and the second smoke outlet.

[0060] In this way, when extracting oil smoke, when the oil smoke in the pot is sprayed out at a higher speed or a higher position, if the amount of oil smoke is large, the amount of oil smoke will rise in large quantities, and smoking will be mainly done by inhaling from above. At this time, the adjusting plate driving member 17 can drive the adjusting plate 16 to move close to the smoke outlet of the second flue 13, and the adjusting plate 16 can relatively cover the smoke outlet part of the second flue 13, that is, the first flue 12 is the main flue, and the second flue 13 is the auxiliary flue. The rising oil smoke can be extracted from the first flue 12, and the second flue 13 can assist in extracting the oil smoke from the side.

[0061] When the oil smoke in the pot gushes out at a slower speed or at a lower position, the oil smoke is mainly sucked from the side. At this time, the adjusting plate driving member 17 can drive the adjusting plate 16 to move close to the smoke outlet of the first flue 12, and the adjusting plate 16 can relatively cover the smoke outlet part of the first flue 12. At this time, the first flue 12 is used as an auxiliary flue, and the second flue 13 is the main flue.

[0062] The regulating plate 16 can be adjusted according to the actual amount of oil smoke, so as to maximize the smoke extraction efficiency and prevent the oil smoke from overflowing.

[0063] It should be noted that the above-mentioned oil fume outlets are provided with two, so there are only one oil fume outlet at the top and one oil fume outlet at the side. In other cases, three or more flues can be provided, and three or more corresponding oil fume suction outlets can also be provided. One oil fume suction outlet is provided at the top, and at least two are provided in the height direction of the side of the shell 10, so that there are more options for the oil fume inlet.

[0064] More specifically, the adjustment plate 16 is pivotally connected to the main flue 11, and the adjustment plate driving member 17 is used to drive the adjustment plate 16 to rotate. In the case where two flues are provided, the adjustment plate 16 can be provided between the smoke outlets of the first flue 12 and the second flue 13, and the adjustment plate driving member 17 can be used to drive the adjustment plate 16 to rotate toward different smoke outlets. When the adjustment plate 16 is rotated to different positions, the opening and closing angles of the smoke outlets of the first flue 12 or the second flue 13 can be adjusted, and the adjustment range is more flexible.

[0065] Of course, when there are multiple flues, an adjustment plate 16 can be provided between two adjacent flues, and the adjustment plate 16 can be rotated between the smoke outlets of the two adjacent flues.

[0066] In addition, the adjustment plate 16 may also be in linear motion, and the adjustment plate 16 may be extended or retracted in the main flue 11 . However, the use of linear motion relative to rotational motion requires a larger movement space, thereby increasing the volume of the shell 10 .

[0067] Furthermore, a fume sensor 141 is provided in the first fume suction port 14, and the fume sensor 141 can detect the amount of fume. The adjustment plate driving member 17 can drive the adjustment plate 16 to move according to the amount of fume, and adjust the power of the variable frequency fan at the same time.

[0068] When the amount of oil smoke in the first flue 12 is small, the adjusting plate driving member 17 can drive the adjusting plate 16 to rotate close to the smoke outlet of the first flue 12, cover the part of the first flue 12, and the second flue 13 can be opened to a greater extent and used as the main flue. When the oil smoke concentration increases significantly, that is, the oil smoke volume of the first flue 12 increases, the adjusting plate driving member 17 can drive the adjusting plate 16 to rotate according to the oil smoke volume, and can move the adjusting plate 16 toward the smoke outlet of the second flue 13, so that the smoke outlet of the first flue 12 can be opened to a greater extent, and the power of the variable frequency fan is automatically increased, and the first flue 12 can discharge a larger amount of oil smoke.

[0069] When the oil fume concentration exceeds the limit value of the oil fume sensor, the adjustment plate driving part 17 can drive the adjustment plate 16 to rotate close to the smoke outlet of the second flue 13 and completely cover the second flue. The smoke outlet of the first flue 12 is opened to the maximum value. At this time, the air suction volume of the first flue 12 is equal to that of the main flue 11. At the same time, the power of the variable frequency fan is automatically adjusted to the maximum value to discharge the oil fume to the greatest extent.

[0070] Furthermore, a fan may be provided in the main flue 11, and the fan is used to receive the oil fume signal. In the present embodiment, the fan may be a variable frequency fan in the prior art. When the amount of oil fume is large, the variable frequency fan may adjust the fan frequency, increase the speed, increase the wind pressure, and enhance the suction force according to the oil fume signal detected by the oil fume sensor 141, thereby ensuring that no smoke is missed. When the oil fume concentration is significantly reduced, the speed of the variable frequency fan is reduced, and the wind pressure is automatically reduced, thereby effectively saving energy and reducing noise. In this way, maximum energy saving can be achieved.

[0071] Of course, a control panel and a controller may be provided at the top of the shell 10. The control panel may receive the detection result of the oil fume sensor 141, and then the controller may control the variable frequency fan and the adjusting plate driving member 17 in a timely manner according to the detection structure.

[0072] Furthermore, an oil fume filter 18 is provided at the bottom end of the main flue, that is, after the oil fume is discharged from multiple flues to the main flue, the oil fume can be filtered through the oil fume filter 18, and the oil in the oil fume can be filtered out through the oil fume filter 18, so that the smoke discharged from the smoke-oil system is more environmentally friendly and reduces the oil fume adhering to the outlet.

[0073] Furthermore, a first oil guide plate 111 is provided on the bottom side wall of the main flue 11, and the first oil guide plate 111 is gradually inclined inward from top to bottom, so that the first oil guide plate 111 can block the oil in the main flue 11 and guide the oil droplets to be discharged downward through the outlet.

[0074] More specifically, a second oil guide plate 112 may be provided on the bottom side wall of the main flue 11. The second oil guide plate 112 is provided on a side of the main flue 11 away from the first oil guide plate 111. The first oil guide plate 111 and the second oil guide plate 112 are spaced apart in sequence in the height direction of the main flue 11. The second oil guide plate 112 can pour oil on the opposite side of the first oil guide plate 111. The first oil guide plate 111 and the second oil guide plate 112 can guide oil droplets out in different directions and guide the oil centrally, which is convenient for centralized cleaning later.

[0075] Furthermore, the shell 10 in this embodiment includes a first panel 20, a second panel 30 and two side panels 40, and the first panel 20 and the second panel 30 are arranged at intervals; the two side panels 40 are respectively connected to the two sides of the first panel 20 and the second panel 30, so that a smoking space can be enclosed by the first panel 20, the second panel 30 and the two side panels 40, and partitions are arranged in the first panel 20 and the second panel 30 to separate them into a flue. In this way, a flue can be formed by simply assembling different panels through a screw structure, which is convenient for disassembly and cleaning and easy to process.

[0076] In addition, the top of the first panel 20 is bent toward the second panel 30 to form a bent plate 21, and the bent plate 21 can be spaced apart from the top of the second panel 30. The bent plate 21 is provided with an oil smoke suction port, and the bent plate 21 can block the rising oil smoke and guide it out through the oil smoke suction port on the bent plate 21. In addition, the top of the second panel 30 and the partition plate provided between the first panel 20 and the second panel 30 can also be spaced apart to form an oil smoke suction port, without the need for an additional opening on the second panel 30, and the processing is also convenient.

[0077] In the above structure, when the shell and the stove are assembled, the first panel and the second panel of the shell can be assembled on the stove, and the flue between the first panel and the second panel can pass through the interior of the stove to discharge oil smoke.

[0078] Furthermore, a waterproof baffle 50 can be provided on the inner side of the second panel. The waterproof baffle can be installed between the assembly gap between the second panel and the top surface of the stove, which can effectively prevent water stains from entering the flue through the assembly gap during operation of the stove, thereby achieving a better waterproof effect.

[0079] More specifically, a sealing ring may be clamped between the waterproof baffle and the second panel and the end surface of the stove, thereby achieving a better waterproof effect.

[0080] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
