[0002] Integrated stoves are often integrated with the stove and hood, and can be used to extract the generated fumes during cooking. However, in different cooking scenarios, the speed and amount of fumes generated are different. Especially in the case of high-heat stir-frying, the speed of fumes generated is fast and the amount of fumes is large. The integrated stove cannot extract the fumes in a short time, resulting in fumes overflowing, polluting the kitchen environment and causing harm to the human body. Currently, there are integrated stoves with top suction structures (CN204285565U), but since the top suction structure is set on the integrated stove body, it can only act on the fumes below the top of the integrated stove, and cannot act on the fumes that have reached the top of the integrated stove or have overflowed above the top of the integrated stove, and the anti-overflow effect is poor.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present application. In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0034] When a numerical range is disclosed herein, the above range is deemed to be continuous and includes the minimum and maximum values ​​of the range, as well as each value between such minimum and maximum values. Further, when a range refers to an integer, each integer between the minimum and maximum values ​​of the range is included. In addition, when multiple ranges are provided to describe features or characteristics, the ranges can be merged. In other words, unless otherwise indicated, all ranges disclosed herein should be understood to include any and all sub-ranges included therein. For example, a specified range from "1 to 10" should be deemed to include any and all sub-ranges between a minimum of 1 and a maximum of 10. Exemplary sub-ranges of ranges 1 to 10 include, but are not limited to, 1 to 6.1, 3.5 to 7.8, 5.5 to 10, etc.

[0035] Because a large amount of oil smoke is generated in a short period of time in certain cooking scenarios such as stir-frying over high heat, the smoke outlet often cannot suck all the generated oil smoke into the smoke passage in time, causing the oil smoke to overflow the integrated stove and cause damage to the ceiling and other cooking facilities. If the oil smoke permeates the cooking area, it will also have an adverse effect on the health of the cook. Therefore, in order to further improve the oil smoke absorption capacity of the integrated stove, increase the amount of smoke in a short period of time, and reduce the possibility of oil smoke overflowing the integrated stove, the present application provides an anti-smoke overflow integrated stove.

[0036] like Figure 1 As shown, an anti-smoke overflow integrated stove provided in the present application has the following structure: an integrated stove body 1, a smoke collecting structure 2, a smoke partition plate 11, a non-smoke partition plate, a base 13, a lighting lamp 14, a top suction fume extraction device 15, and a top suction fume detection device 16; the non-smoke partition plate includes a front plate 121, a back plate, a column 123, a light board 125, and a top 124 of the integrated stove body. Exemplarily, the top 124 of the integrated stove body can be a top plate, wherein the smoke partition plate 11, the front plate 121, the back plate and the column 123 are connected to the base 13, and the light board 125 is arranged inside the integrated stove body 1, and a lamp chamber 1251 formed between the light board 125 and the front plate 121, the smoke partition plate 11, and the top plate isolates the fume, and a lighting lamp 14 is arranged in the lamp chamber 1251.

[0037] In some possible embodiments, the anti-smoke overflow integrated stove includes an integrated stove body 1 and a smoke collection structure 2, and the smoke collection structure 2 is arranged on the top 124 of the integrated stove body;

[0038] The integrated stove body 1 comprises a smoke-isolating plate 11 and a non-smoke-isolating plate, a top suction channel is formed between the smoke-isolating plate 11 and the non-smoke-isolating plate, and the non-smoke-isolating plate is a plate member of the integrated stove body 1 other than the smoke-isolating plate 11;

[0039] Optionally, the connection between the smoke collecting structure 2 and the integrated stove body 1 can be a detachable connection or a fixed connection, or the smoke collecting structure 2 can be independently placed on the top 124 of the integrated stove body, and the inlet of the smoke collecting structure 2 is arranged opposite to the place where the cooking oil smoke is emitted on the integrated stove body 1. When the cooking oil smoke overflows to the inlet of the smoke collecting structure 2, it can enter the top suction channel through the inlet, thereby achieving the effect of preventing the oil smoke from overflowing. The smoke partition 11 is used to divide the side suction channel and the top suction channel, so that the oil smoke entering through the side suction channel and the oil smoke entering through the top suction channel do not contact each other.

[0040] The top suction channel includes a first top suction channel 17 and a second top suction channel 19 which are connected to each other. The outlet of the smoke collecting structure 2 is connected to the inlet 12211 of the first top suction channel. The cross-sectional area of ​​the first top suction channel 17 is greater than the cross-sectional area of ​​the second top suction channel 19.

[0041] It should be noted that the first top suction channel 17 is located at the upper part of the top suction channel. The oil smoke overflowing to the smoke collection structure 2 is sucked into the top suction channel through the inlet 12211 of the first top suction channel and then flows downward. Since this part of the oil smoke has overflowed to the top of the integrated stove, if it is not completely absorbed, it will overflow to the area outside the integrated stove and will not be able to be sucked through the integrated stove. Therefore, it is necessary to absorb all of this part of the oil smoke in a short time. The cross-sectional area of ​​the first top suction channel 17 is set to be larger than the cross-sectional area of ​​the second top suction channel 19, which can ensure that a larger amount of oil smoke can pass through in a short time.

[0042] The embodiment of the utility model arranges a smoke collecting structure on the top of the integrated stove, and the outlet of the smoke collecting structure is connected with the inlet of the top suction channel, so that when the oil smoke overflowing from the top of the integrated stove reaches the smoke collecting structure, it can be collected by the smoke collecting structure and then sucked into the top suction channel, thereby blocking the oil smoke from overflowing outside the integrated stove. The top suction channel is arranged to have a first top suction channel and a second top suction channel with different cross-sectional areas, and the cross-sectional area of ​​the first top suction channel is larger than that of the second top suction channel, thereby increasing the smoke intake and the speed of extracting the oil smoke through the top suction channel, so that the oil smoke near the smoke collecting structure can be quickly sucked away by the top suction channel in a short time. Through the above arrangement, the oil smoke extraction efficiency of the integrated stove is improved, and oil smoke overflow is effectively prevented.

[0043] See also Figure 2 , Figure 3 , Figure 3 is based on Figure 2 In the view obtained through the AA section, in some possible embodiments, at least one top suction range fume extraction device 15 for sucking the fumes into the top suction channel is provided inside the top suction channel, and at least one top suction range fume detection device 16 is provided on the top 124 of the integrated stove body, and the at least one top suction range fume extraction device 15 is electrically connected to the at least one top suction range fume detection device 16.

[0044] Optionally, the top-suction oil fume detection device 16 can be an oil fume sensor, an oil fume detector or other device, which is used to detect whether there is oil fume near the top of the integrated stove body 1. For example, a preset threshold indicating the maximum amount of oil fume can be set for the oil fume sensor. When it is detected that the amount of oil fume is greater than or equal to the preset threshold, the oil fume sensor sends a signal to control the top-suction oil fume extraction device 15 to perform oil fume extraction operation.

[0045] Furthermore, the number of the top suction range fumes extraction devices 15 can be 1, 2, 3, 4 or more. Preferably, when there are 2 top suction range fumes extraction devices 15, the number of the top suction range fumes detection devices 16 is also 2, and the top suction range fumes extraction devices 15 can be placed on the left and right sides of the first top suction channel 17, respectively, and the top suction range fumes detection devices 16 can be placed on the left and right sides of the top 124 of the integrated stove body, respectively. When the top suction range fumes detection devices 16 on either the left or right side detect the fumes, the corresponding top suction range fumes extraction devices 15 are independently controlled to absorb the fumes, and the top suction range fumes extraction devices 15 and the top suction range fumes detection devices 16 correspond one to one, and the corresponding top suction range fumes extraction devices 15 independently control the top suction range fumes detection devices 16.

[0046] The embodiment of the utility model arranges a top suction oil fume detection device on the top of the integrated stove body, and arranges a top suction oil fume extraction device electrically connected to the top suction oil fume detection device inside the top suction channel. When the top suction oil fume detection device detects oil fume, a signal is sent to control the corresponding top suction oil fume extraction device to extract oil fume. The top suction oil fume extraction device is turned on only when oil fume is detected, and there is no need to keep the top suction oil fume extraction device turned on continuously. Since the top suction oil fume detection device is arranged at different positions, the top suction oil fume extraction device at a suitable position can be flexibly controlled according to the actual oil fume monitoring situation, avoiding energy waste caused by opening multiple top suction oil fume extraction devices at the same time, thereby improving the economy of electricity use, saving energy, reducing energy consumption, and improving the intelligence of the integrated stove oil fume extraction control and the pertinence of the oil fume extraction operation.

[0047] See also Figure 4 The oil smoke flow process of the anti-smoke overflow integrated stove provided by the utility model is as follows Figure 4As shown, for the fumes generated at the place where cooking fumes are emitted, under the action of the side suction fume extraction device 5, most of the fumes enter the side suction channel 3 through the inlet 31 of the side suction channel on the front plate 121. If there is a small amount of fumes overflowing to the top of the integrated stove body, it enters the channel 23 of the smoke collection structure 2, and is guided by the second top cover plate 212. It enters the first top suction channel 17 through the inlet 12211 of the first top suction channel set on the top of the first back plate 1221, and enters the second top suction channel 19 with a smaller cross-sectional area through the transition channel 18. The second top suction channel 19 and the side suction channel 3 are connected to the total smoking channel 4, and the sum of the cross-sectional area of ​​the second top suction channel 19 and the cross-sectional area of ​​the side suction channel 3 is equal to the cross-sectional area of ​​the total smoking channel 4.

[0048] See also Figure 3 , Figure 4 , Figure 5 In some possible embodiments, the non-smoke isolation plate includes a front plate 121, a side suction channel 3 is formed between the front plate 121 and the smoke isolation plate 11, an inlet 31 of the side suction channel is arranged on the front plate 121, and the ratio of the cross-sectional area of ​​the second top suction channel 19 to the cross-sectional area of ​​the side suction channel is a preset ratio.

[0049] The side suction channel is used to absorb most of the oil smoke emitted from cooking oil smoke. Optionally, the cross-sectional area of ​​the side suction channel needs to be set to a larger value to ensure that the entrance of the side suction channel can absorb more oil smoke in the same time, reduce the oil smoke overflowing to the top of the integrated stove body 1, and prevent oil smoke overflow.

[0050] It should be noted that the second top suction channel 19 is located at the lower part of the top suction channel, and the oil smoke passing through the inlet 12211 of the first top suction channel 17 flows downward through the second top suction channel 19. The sum of the cross-sectional area of ​​the second top suction channel 19 and the cross-sectional area of ​​the side suction channel is the total smoking channel cross-sectional area. When the total smoking channel cross-sectional area is a preset value, the sum of the cross-sectional areas of the second top suction channel 19 and the side suction channel is determined. When the cross-sectional area of ​​the second top suction channel 19 increases, the cross-sectional area of ​​the side suction channel decreases. Since the second top suction channel 19 does not need to inhale a large amount of oil smoke in a short time, reducing the channel cross-sectional area of ​​the second top suction channel 19 and increasing the cross-sectional area of ​​the side suction channel can ensure that the side suction channel inhales a large amount of oil smoke and prevent the phenomenon of oil smoke overflow caused by incomplete absorption of oil smoke.

[0051] Optionally, the ratio of the cross-sectional area of ​​the second top suction channel 19 to the cross-sectional area of ​​the side suction channel is a preset ratio, and the preset ratio is less than 1. Preferably, the preset ratio may be 1 / 5, 1 / 4, 1 / 3, etc.

[0052] The embodiment of the utility model limits the ratio of the cross-sectional area of ​​the second top suction channel and the cross-sectional area of ​​the side suction channel to a preset ratio, so that the cross-sectional area of ​​the second top suction channel is significantly smaller than the cross-sectional area of ​​the side suction channel, thereby ensuring that the inlet cross-sectional area of ​​the side suction channel is large enough. Under the action of the range fumes extraction device, the amount of oil smoke extracted in the same period of time is greater and the speed of inhaling oil smoke is faster. The cross-sectional area of ​​the top suction channel is reduced from the cross-sectional area of ​​the first top suction channel to the cross-sectional area of ​​the second top suction channel. Under the premise of ensuring that the first top suction channel inhales oil smoke quickly and in a large amount of oil smoke, the space occupied by the side suction channel is reduced, thereby ensuring the effect of the side suction channel in absorbing oil smoke, reducing the amount of oil smoke overflowing to the top of the integrated stove from the source, and reducing the amount of oil smoke that needs to be inhaled by the top suction channel, thereby forming a virtuous circle between the functional realization of the top suction channel and the side suction channel, which is more conducive to preventing oil smoke overflow.

[0053] See also Figure 6 , Figure 7 , Figure 7 The appearance of the integrated stove body 1 when the smoke isolation plate 11 is not installed is shown. Figure 6 The appearance of the integrated stove body 1 after the smoke isolation plate 11 is installed on the integrated stove body 1 is shown, and the top suction range fumes extraction device 15 is hidden behind the smoke isolation plate 11. Please continue to refer to Figure 1 , Figure 3 , Figure 5 As shown in the figure, in some possible embodiments, the smoke isolation plate 11 includes a first straight plate 111, a connecting plate 112 and a second straight plate 113, and the first straight plate 111 and the second straight plate 113 are connected by the connecting plate 112.

[0054] Optionally, the smoke isolation board 11 is an integral board, and the manufacturing process can be integral pressing. Preferably, the smoke isolation board 11 is an irregular integral board, and according to the shape and size characteristics, the smoke isolation board 11 includes three parts, namely, a first straight board 111, a connecting board 112 and a second straight board 113.

[0055] On the integrated stove body 1, one end of the first straight plate 111 is connected to the top 124 of the integrated stove body, and the other end is connected to one end of the connecting plate 112, the first straight plate 111 is parallel to the back plate, the second straight plate 113 is parallel to the first straight plate 111, one end of the second straight plate 113 is connected to the other end of the connecting plate 112, and the other end of the second straight plate 113 is connected to the base, the line segment distance obtained by drawing a perpendicular line from any point on the first straight plate 111 to the back plate is the first distance, and the line segment distance obtained by drawing a perpendicular line from any point on the second straight plate 113 to the back plate is the second distance, and the second distance is smaller than the first distance.

[0056] The embodiment of the utility model sets the smoke shield plate as an irregular one-piece plate, so that the cross-sectional area of ​​the top suction channel formed by the smoke shield plate installed in the integrated stove is more in line with actual needs. By setting the first distance between the first straight plate and the back plate to be greater than the second distance between the second straight plate and the back plate, the cross-sectional area of ​​the first top suction channel is greater than that of the second top suction channel, so that the entrance of the top suction channel can absorb a larger amount of oil smoke in the same time, thereby more quickly and effectively suppressing the oil smoke that is about to overflow from the top of the integrated stove.

[0057] Please continue to see Figure 3 , Figure 4 , Figure 5 As shown in the figure, in some possible embodiments, the non-smoke barrier panel also includes a back panel, and the back panel includes a first back panel 1221 and a second back panel 1222. The entrance 12211 of the first top suction channel 17 is set on the top of the first back panel 1221. The first top suction channel 17 is formed between the first back panel 1221 and the first straight panel 111, and the second top suction channel 19 is formed between the second back panel 1222 and the second straight panel 113.

[0058] The first back plate 1221 and the second back plate 1222 are detachably connected, and the first back plate 1221 and the second back plate 1222 can be connected via a snap-fit ​​structure.

[0059] The first top suction channel 17 is provided with a top suction range fumes device 15. For example, the top suction range fumes device 15 can be a fan assembly. Since it is necessary to reserve space for installing the top suction range fumes device 15, the cross-sectional area of ​​the side suction channel must be large enough. The top suction range fumes device 15 of the top suction channel is at the top. The second top suction channel 19 is only used for flowing oil smoke. Therefore, it is not necessary to reserve installation space, and the cross-sectional area of ​​the second top suction channel 19 does not need to be too large. The cross-sectional area of ​​the first top suction channel 17 is larger than the cross-sectional area of ​​the second top suction channel 19. On the one hand, the first top suction channel 17 is used to absorb the overflow oil smoke in a short time, and on the other hand, it is used to provide the top suction range fumes device 15 with an installation space to flow out.

[0060] The embodiment of the utility model divides the top suction channel into a first top suction channel and a second top suction channel by setting the cross-sectional area of ​​the channel between the back plate and the smoke partition plate. By setting the cross-sectional area of ​​the first top suction channel to be larger than the cross-sectional area of ​​the second top suction channel, there is space in the first top suction channel to set a top suction fume extraction device, which can enhance the suction capacity of overflowing oil fume, and reduce the cross-sectional area of ​​the second top suction channel, which can reduce the crowding out of the side suction channel, ensure the channel cross-sectional area of ​​the side suction channel, and enhance the fume extraction capacity of the side suction channel.

[0061] Please continue to see Figure 3 , Figure 4 , Figure 5As shown in the figure, in some possible embodiments, a transition channel 18 is formed between the connecting plate 112 and the back plate, and the first top suction channel 17 and the second top suction channel 19 are connected through the transition channel 18.

[0062] Optionally, the connecting plate 112 between the first straight plate 111 and the second straight plate 113 can be a curved plate or a straight plate. The channel formed between the connecting plate 112 and the back plate connects the first top suction channel 17 and the second top suction channel 19. On the one hand, the connecting plate 112 can complete the transition of the cross-sectional area of ​​the top suction channel from a large cross-sectional area to a small cross-sectional area, thereby forming a buffer for the oil smoke. On the other hand, the connecting plate 112 is conducive to guiding the oil droplets to slide off.

[0063] Furthermore, the curvature of the connecting plate 112 may be determined according to the size of the top suction range fume extraction device 15 disposed in the first top suction channel 17 .

[0064] The embodiment of the utility model arranges a connecting plate to form a transition channel between the connecting plate and the back plate, thereby achieving a transition between the cross-sectional area of ​​the first top suction channel and the cross-sectional area of ​​the second top suction channel, so that the cross-sectional area of ​​the first top suction channel is larger, which is more suitable for inhaling as much oil fume as possible in a short time, ensuring that the oil fume overflowing to the top of the integrated stove is sucked, and at the same time ensuring that the second top suction channel does not occupy the cross-sectional area of ​​the side suction channel, ensuring that the side suction channel continues to inhale a large amount of oil fume, and minimizing the oil fume overflowing to the top of the integrated stove, thereby forming a good coordination between the side suction channel and the top suction channel, and enhancing the side suction effect and the top anti-overflow effect of the anti-overflow integrated stove.

[0065] Please continue to see Figure 3 , Figure 4 , Figure 5 As shown in the figure, in some possible embodiments, the smoke collection structure 2 includes a top cover plate and a side cover plate 22, the top cover plate includes a first top cover plate 211, the first top cover plate 211 is arranged parallel to the top 124 of the integrated stove body, and the angle between the first top cover plate 211 and the side cover plate 22 is greater than 90°.

[0066] Taking the shape of the integrated stove when it is normally placed as a reference, preferably, the top cover plate of the smoke collecting structure 2 is used to collect the oil smoke that is about to overflow the integrated stove. This requires that the top cover plate has a strong force to collect the oil smoke. By arranging the side cover plate 22 which is tilted relative to the top of the integrated stove body 1 instead of being placed vertically, the smoke collecting structure 2 arranged on the top 124 of the integrated stove body can be narrow at the top and wide at the bottom, so that the oil smoke entering the smoke collecting structure 2 is gathered, reducing the possibility of oil smoke diffusion and overflow.

[0067] Optionally, the distance between the line where the side cover plate 22 contacts the top 124 of the integrated stove body and the side edge of the top of the integrated stove body 1 is a preset distance, and the side edge of the top of the integrated stove body 1 is the edge on the top of the integrated stove body 1 parallel to the air inlet direction of the smoke collection structure 2. Exemplarily, when the preset distance is 0, the smoke collection structure 2 covers the entire top 124 of the integrated stove body; when the preset distance is not 0, the smoke collection structure 2 partially covers the top 124 of the integrated stove body.

[0068] Furthermore, the surface area of ​​the first top cover plate 211 may be larger than the surface area of ​​the top 124 of the integrated stove body, and one end of the first top cover plate 211 close to the surface of the integrated stove may extend out of the top 124 of the integrated stove body, or may not extend out of the top 124 of the integrated stove body.

[0069] Furthermore, the angle between the first top cover panel 211 and the side cover panel 22 can be 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, etc.

[0070] Further, the first surface is a surface perpendicular to the air inlet direction of the smoke collecting structure 2. The side cover plate 22 includes a first side cover plate 22 and a second side cover plate 22 respectively arranged on both sides of the top cover plate.

[0071] On the first surface, the cross-section of the structure formed between the smoke collecting structure 2 and the top 124 of the integrated stove body is a trapezoid, the first top cover plate 211 of the smoke collecting structure 2 is the first parallel side of the trapezoid, the top 124 of the integrated stove body is in contact with the first side cover plate 22 and the second side cover plate 22 respectively to form a first line segment and a second line segment, and on the first surface, the first line segment and the second line segment respectively form a first intersection point and a second intersection point, the distance between the first intersection point and the second intersection point is the second parallel side of the trapezoid, and the plate body of the first side cover plate 22 and the plate body of the second side cover plate 22 themselves are the two waists of the trapezoid on the first surface.

[0072] The embodiment of the utility model arranges a first top cover plate parallel to the top of the integrated stove body on the top of the integrated stove body, and arranges a side cover plate with an angle greater than° between the side cover plate and the first top cover plate, so that a structure that is narrow at the top and wide at the bottom is formed between the smoke collecting structure and the top of the integrated stove body, which is beneficial for collecting oil smoke overflowing to the top of the integrated stove, enhancing the smoke collecting effect of the smoke collecting structure, and absorbing the oil smoke overflowing to the top of the integrated stove body into the top suction channel through the smoke collecting structure, thereby enhancing the anti-smoke overflow effect of the anti-smoke overflow integrated stove.

[0073] Please continue to see Figure 3 , Figure 4 , Figure 5As shown in the figure, in some possible embodiments, the top cover plate also includes a second top cover plate 212, and the end of the second top cover plate 212 away from the entrance of the smoke collection structure 2 is connected to the top of the first back plate 1221, and the angle between the second top cover plate 212 and the first top cover plate 211 is greater than 90°.

[0074] In some possible embodiments, the distance between the first top cover plate 211 and the top 124 of the integrated stove body is a first distance, and the distance between the second top cover plate 212 and the top 124 of the integrated stove body is a second distance, and the second distance is less than or equal to the first distance.

[0075] See also Figure 2 or Figure 3 From the right side view of the integrated stove, one end of the second top cover plate 212 close to the entrance of the smoke collecting structure 2 is connected to one end of the first top cover plate 211. The position of the second top cover plate 212 is obtained by rotating the first top cover plate 211 clockwise at an acute angle. The first top cover plate 211 is parallel to the top 124 of the integrated stove body, and the second top cover plate 212 forms an acute angle with the top 124 of the integrated stove body. The closer the distance between any point on the second top cover plate 212 and the top of the first back plate 1221, the shorter the vertical line segment from the any point to the top 124 of the integrated stove body. The distance between any point on the line segment formed by the second top cover plate 212 and the top of the first back plate 1221 and the top 124 of the integrated stove body is the minimum second distance.

[0076] The embodiment of the utility model sets the angle between the second top cover plate and the first top cover plate to be greater than 90°, so that after the oil smoke enters the smoke collection structure, the size of the channel is tightened, and the cross-sectional area of ​​the channel formed between the second top cover plate, the top of the integrated stove body and the side cover plates gradually becomes smaller, thereby guiding and strengthening the collection of the oil smoke, allowing the oil smoke to be smoothly introduced into the first top suction channel, which can increase the speed of extracting the oil smoke and further enhance the effect of absorbing the oil smoke and preventing the oil smoke from overflowing.

[0077] In some possible embodiments, the sum of the cross-sectional area of ​​the second top suction channel 19 and the cross-sectional area of ​​the side suction channel 3 is the cross-sectional area of ​​the total smoking channel 4 .

[0078] See also Figure 8 ,like Figure 8As shown, a smoke collecting structure 2 is arranged on the top 124 of the integrated stove body of the anti-smoke overflow integrated stove provided in the present application, and the smoke collecting structure 2 is arranged opposite to the place where the cooking fume is emitted on the integrated stove body 1. A top suction fume detection device 16 is arranged on the top 124 of the integrated stove body, and is also arranged opposite to the place where the cooking fume is emitted. The inlet 31 of the side suction channel is arranged on the front plate 121. Most of the fume generated at the place where the cooking fume is emitted is sucked into the side suction channel 3. When the top suction fume detection device 16 detects that part of the fume is overflowing, it sends a top suction fume extraction control signal to the top suction fume extraction device 15 to control the top suction fume extraction device 15 to perform the fume extraction operation.

[0079] The embodiment of the utility model sets a one-to-one corresponding top suction oil fume detection device and a top suction oil fume extraction device, so that the top suction oil fume detection device can independently control the top suction oil fume extraction device corresponding thereto, and control the top suction oil fume extraction device at the appropriate position to extract oil fume according to the specific situation of the oil fume amount at different positions, thereby improving the pertinence of controlling the extraction of oil fume at different positions, and only controlling the corresponding top suction oil fume extraction device to extract oil fume when oil fume is detected, and not starting the top suction oil fume extraction device when oil fume is not detected, thereby avoiding energy waste and improving the concentration and efficiency of energy utilization. When oil fume is concentrated in a certain position, it can be detected by the top suction oil fume detection device near the position, and the nearest top suction oil fume extraction device can be controlled to extract oil fume, thereby improving the accuracy of controlling the extraction of oil fume, and further strengthening the anti-overflow effect of the anti-overflow integrated stove.

[0080] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
