Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to a machine head and an integrated stove. Background Art

[0002] An integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection.

[0003] The head of an existing integrated stove usually includes a head body, which includes a smoke guide plate located on the operating side and a back plate located on the opposite operating side. The smoke guide plate and the back plate are connected and define a smoking channel. Under the negative pressure provided by the fan, the oil smoke generated during cooking can be sucked into the smoking channel. However, the existing heads usually have the following problems during use:

[0004] 1) Due to the high temperature characteristics of the oil smoke itself, the temperature of the related components located in the oil smoke path will increase significantly. Even after the integrated stove is used, the temperature of the related components of the machine head can only cool down slowly. During this period, the oil stains attached to the machine head, especially the inner surface of the channel wall of the smoking channel, are difficult to condense into oil droplets in time. Instead, they are more likely to form wall accumulation, which is easy to produce odor and affect the user experience after long-term use.

[0005] 2) The upper edge of the smoke guide plate guides the oil smoke to the smoke inlet and enters the smoking channel. Therefore, the upper edge of the smoke guide plate is the only way for the oil smoke. There is serious oil accumulation, which is easy to flow to the outer surface of the smoke guide plate and even to the countertop of the stove. It is laborious to clean and affects the appearance.

[0006] 3) Some machine heads also include a storage table located above the main body of the machine head.

[0048] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions, and the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0052] Please refer to Figures 1 to 6 The present embodiment provides an integrated stove, which includes a head 100, a gas stove 300 and a frame 200, wherein the head 100 and the gas stove 300 are both arranged above the frame 200. The gas stove 300 is used for cooking, and the head 100 is used for collecting and discharging oil smoke generated during cooking.

[0053] Specifically, the integrated stove further includes a smoke exhaust fan 500 disposed inside the frame 200, and the head 100 includes a head body 1, and the head body 1 includes a smoking passage 11, and the smoking passage 11 has a smoke inlet 12 connected to the outside. Under the action of the negative pressure provided by the smoke exhaust fan 500, the oil smoke generated during cooking can enter the smoking passage 11 through the smoke inlet 12, and then be discharged into the smoke exhaust duct.

[0054] Optionally, the integrated stove further includes a functional module 400 installed on the frame 200, and the functional module 400 may be a functional device such as a disinfection cabinet, a steamer, an oven, etc. By integrating different functional modules 400 in the integrated stove, different functions can be integrated into the integrated stove to meet different needs of users.

[0055] During the use of the integrated stove in the prior art, the high temperature characteristics of the oil smoke itself will cause the temperature of the related components located in the path of the oil smoke to increase significantly. Even after the integrated stove is used, the temperature of the related components of the machine head can only be cooled slowly. During this period, the oil stains attached to the machine head, especially the inner surface of the channel wall of the smoking channel, are difficult to condense into oil droplets in time. Instead, they are more likely to form wall accumulation, which is likely to produce odor and affect the user experience after long-term use.

[0056] For this, please refer to Figure 2 , Figure 4 and Figure 6 In this embodiment, the head body 1 includes an air cooling channel 21 where the smoking channel 11 is located. In this way, heat exchange can be performed between the air with a lower temperature in the air cooling channel 21 and the channel wall of the smoking channel 11 located in the air cooling channel 21, so as to reduce the channel wall temperature of the smoking channel 11, thereby causing the oil stains attached to the inner surface of the channel wall of the smoking channel 11 to condense into oil droplets, which can effectively avoid the generation of odor and improve user experience.

[0057] Optionally, the air cooling channel 21 has a first air inlet 22 communicating with the outside, and the air with a lower temperature in the outside can enter the air cooling channel 21 through the first air inlet 22 to continuously cool the channel wall of the smoking channel 11 .

[0058] In order to ensure that the outside air can continuously enter the air cooling channel 21, a condensing fan can also be provided, and the input end of the condensing fan is connected to the air cooling channel 21. Under the drive of the condensing fan, the air with a lower temperature in the outside can enter the air cooling channel 21 through the first air inlet 22. Alternatively, the input end of the smoke exhaust fan 500 is connected to the air cooling channel 21 and the smoking channel 11 at the same time, and the smoke exhaust fan 500 can provide negative pressure to the air cooling channel 21 and the smoking channel 11 at the same time, which can effectively reduce the number of fans used and effectively simplify the structure of the integrated stove.

[0059] In addition, the number of the first air inlet 22 can be set according to actual needs, and can be set to one or more. For example, the first air inlet 22 can be set to a long strip of large holes, or can be set to be along the left and right directions of the integrated stove (such as Figure 3 direction as indicated by arrows ab) or height direction (as shown in Figure 3 It is composed of a plurality of small holes arranged at intervals (in the direction indicated by the arrow cd).

[0060] It should be noted that the air entering the air cooling channel 21 from the first air inlet 22 can be ambient air or cold air provided by a refrigeration mechanism, and the temperature of this part of air is lower than the temperature of the fumes generated during the cooking process. Among them, in this embodiment, an exemplary scheme is given in which the air entering the air cooling channel 21 from the first air inlet 22 is ambient air. Preferably, the first air inlet 22 is disposed on the side or rear of the head body 1, so that the air entering from the first air inlet 22 can be prevented from being affected by the heat emitted during the cooking process. Specifically, in this embodiment, an exemplary scheme is given in which the first air inlet 22 is disposed on the side of the head body 1.

[0061] In this embodiment, the smoking passage 11 is entirely located in the air cooling passage 21, and the smoking passage 11 can be entirely wrapped by the air cooling passage 21. The air flowing through the air cooling passage 21 can perform heat exchange on the entire passage wall of the smoking passage 11 in all directions, so as to fully ensure the cooling effect on the passage wall of the smoking passage 11. In other embodiments, a part of the smoking passage 11 can also be located in the air cooling passage 21 as required. For example, the air cooling passage 21 may include a plurality of sub-passages, and the plurality of sub-passages are evenly spaced and distributed along the outer periphery of the smoking passage 11, and each sub-passage is used to cool a part of the passage wall of the smoking passage 11, so as to ensure the cooling effect on the passage wall of the smoking passage 11.

[0062] Optionally, a plurality of fins are convexly provided on the outer surface of the channel wall of the smoking channel 11, and the plurality of fins are evenly distributed along the circumference of the smoking channel 11. Such a configuration can effectively increase the heat exchange area between the air in the air cooling channel 21 and the smoking channel 11, so as to further enhance the cooling effect on the channel wall of the smoking channel 11.

[0063] It should be noted that the number of the smoking passages 11 provided in the head body 1 may be one or more. When the number of the smoking passages 11 is more than one, the number of the air cooling passages 21 may be the same as the number of the smoking passages 11, and the passage walls of the more than one smoking passages 11 may be cooled down through the more than one air cooling passages 21, or the number of the air cooling passages 21 may be less than the number of the smoking passages 11, in which case at least a portion of the air cooling passages 21 cools down the passage walls of the more than one smoking passages 11 at the same time.

[0064] As an alternative solution, a condensing component is used to provide cooling to the channel wall of the smoking channel 11. The condensing component includes a compressor, a condenser, a throttle valve and an evaporator. The compressor, the condenser, the throttle valve and the evaporator constitute an air-conditioning circuit. The evaporator can be arranged in the smoking channel 11, and the cooling dissipated by the evaporator is used to cool the smoke flowing through the smoking channel 11. Alternatively, the evaporator can also be arranged outside the smoking channel 11. The condensing component also includes a fan. The fan faces the evaporator, and the fan blows the cooling dissipated by the evaporator to the channel wall of the smoking channel 11 to cool the channel wall of the smoking channel 11.

[0065] Optionally, see Figures 2 to 5 The head 100 further includes a storage table 4 disposed above the head body 1, and electronic components 9 disposed on the storage table 4. The storage table 4 is used to place condiments, tableware and other items. The electronic components 9 can be lighting, touch screens, control buttons or sensors, etc. Specifically, the number and types of the electronic components 9 can be set according to actual needs.

[0066] In the existing integrated stove, during the use of the integrated stove, the electronic components on the storage table are easily exposed to a high temperature environment, which will reduce the service life of the electronic components.

[0067] In this regard, in this embodiment, the storage table 4 includes a heat dissipation channel 42 connected to the air cooling channel 21, the heat dissipation channel 42 has a second air inlet 43 connected to the outside, and the electronic component 9 is partially located in the heat dissipation channel 42. In this arrangement, under the drive of the condensing fan, air can also enter the heat dissipation channel 42 through the second air inlet 43 and perform heat exchange with the electronic component 9 to reduce the temperature of the electronic component 9, avoid the electronic component 9 from working at high temperature, and thus extend the service life of the electronic component 9.

[0068] The storage table 4 in this embodiment includes a storage table housing 41, and the heat dissipation channel 42 is located in the storage table housing 41. Specifically, the storage table housing 41 includes a connecting portion 411 extending in the vertical direction, and a supporting portion 412 connected to the top of the connecting portion 411, the bottom end of the connecting portion 411 is connected to the head body 1, the supporting portion 412 is horizontally arranged, and the supporting portion 412 is used to support items. The electronic component 9 is arranged on the supporting portion 412, and the heat dissipation channel 42 is formed by the supporting portion 412 and the connecting portion 411.

[0069] Specifically, the rear end of the support portion 412 of the storage platform housing 41 is connected to the connection portion 411, and the front end is suspended and extends forward, so that the storage platform 4 has not only the storage function but also the function of collecting cigarettes. In other embodiments, the storage platform 4 can also be configured to have only the storage function but not the function of collecting cigarettes, or the storage platform 4 can have only the function of collecting cigarettes but not the storage function.

[0070] It should be noted that the air entering from the second air inlet 43 can be ambient air at room temperature or cold air provided by a refrigeration mechanism. In this embodiment, the air entering from the second air inlet 43 is exemplarily provided as ambient air at room temperature.

[0071] In this embodiment, the number of second air inlets 43 can be set according to actual needs, and can be set to one or more. For example, the second air inlet 43 can be set to a large long hole, or it can be set to be composed of multiple small holes arranged at intervals along the left and right directions of the integrated stove.

[0072] Optionally, see Figure 3 , the second air inlet 43 is disposed at the top of the heat dissipation channel 42; and / or, the second air inlet 43 is disposed at the rear end of the heat dissipation channel 42. Such an arrangement can avoid or reduce the influence of the heat generated during cooking on the temperature of the air entering the heat dissipation channel 42 from the second air inlet 43, thereby making the temperature of the air entering the heat dissipation channel 42 from the second air inlet 43 close to normal temperature. In other embodiments, the second air inlet 43 can also be disposed at the side end of the heat dissipation channel 42.

[0073] Optionally, the second air inlet 43 is disposed adjacent to the electronic component 9 , or facing the electronic component 9 , which can fully ensure the cooling effect on the electronic component 9 .

[0074] Optionally, the total area of ​​the first air inlet 22 and the second air inlet 43 is S 1 , the cross-sectional area of ​​the air cooling channel 21 is S 2 , 0.5≤S 1 / S 2 ≤1. Specifically, S 1 / S 2 The value of can be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95 or 1. Such a configuration can effectively introduce enough ambient air at room temperature into the air cooling passage 21 without generating whistling, thereby ensuring the cooling effect on the passage wall of the smoking passage 11.

[0075] Optionally, the cross-sectional area of ​​the smoking channel 11 is S 3 , 0<S 2 / S 3 ≤0.5. Specifically, S 2 / S 3The value of can be 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45 or 0.5. In this configuration, especially when the smoke exhaust fan 500 provides negative pressure to the air cooling channel 21 and the smoking channel 11 at the same time, the channel wall of the smoking channel 11 can be cooled down by the ambient air at normal temperature entering the air cooling channel 21, while fully ensuring that the smoke exhaust effect of the smoking channel 11 is not affected.

[0076] Optionally, see Figures 1 to 5 The head body 11 includes a smoke guide plate 13 located in front of the smoking channel 11, and the smoke guide plate 13 is used to smoothly guide the smoke to the smoke inlet 12 to improve the smoke exhaust capacity of the integrated stove. Figure 3 As shown by the arrow ef.

[0077] Specifically, in this embodiment, the head body 11 also includes a back plate 14 spaced apart from the smoke guide plate 13 in the front-to-rear direction, and two side plates 15 connected between the smoke guide plate 13 and the back plate 14. The smoke guide plate 13, the back plate 14 and the two side plates 15 enclose an air cooling channel 21, and the smoking channel 11 is located in the air cooling channel 21.

[0078] Furthermore, the smoke inlet 12 is located at the top of the smoking passage 11, and the smoke guide plate 13 is roughly L-shaped, with a smooth transition at the corner. The smoke guide plate 13 first guides the oil smoke to flow in the vertical direction and then smoothly transitions to the horizontal direction, and continues to guide the oil smoke to flow in the horizontal direction to the top of the smoke inlet 12, so that the oil smoke smoothly enters the smoking passage 11, so as to ensure the smoke guide plate 13's ability to guide the oil smoke. In other embodiments, the smoke inlet 12 can also be opened horizontally toward the front, or opened obliquely upward.

[0079] In the existing integrated stove, the upper edge of the smoke guide plate guides the oil smoke to the smoke inlet and enters the smoking channel. Therefore, the upper edge of the smoke guide plate is the only way for the oil smoke to pass, and oil is seriously accumulated. It is easy to flow to the outer surface of the smoke guide plate and even to the countertop of the stove, which is laborious to clean and affects the appearance.

[0080] For this, please refer to Figure 7 and Figure 8In this embodiment, the head 100 further includes an oil guide channel 5 connected to the smoking channel 11. The oil guide channel 5 penetrates the smoke guide plate 13. The oil guide channel 5 has an oil collection port 51 and an oil discharge port 52. In the vertical direction, the oil collection port 51 is located above the oil discharge port 52. The oil collection port 51 is used to collect the oil flowing on the smoke guide plate 13, and the oil discharge port 52 is used to discharge the oil into the smoking channel 11. When the oil flows downward along the smoke guide plate 13, it will flow into the oil guide channel 5 when passing through the oil collection port 51, and then flow into the smoking channel 11 through the oil guide channel 5 and from the oil discharge port 52, so as to prevent the oil from flowing to the table of the stove, facilitate cleaning, and ensure beauty.

[0081] Optionally, in this embodiment, along the vertical direction, the oil collection port 51 is located between the oil discharge port 52 and the smoke inlet 12, so that when the oil accumulated at the smoke inlet 12 flows downward along the smoke guide plate 13, it can be collected through the oil collection port 51 and transported to the smoking channel 11 through the oil guide channel 5.

[0082] It can be understood that the oil guide channel 5 is arranged at an angle, and the height of the oil guide channel 5 gradually decreases from front to back. Therefore, after the oil enters the oil guide channel 5 from the front oil conduit 51, it can flow to the oil discharge port 52 at the rear end of the oil guide channel 5 under the action of the oil's own gravity.

[0083] Preferably, the oil collection port 51 is close to the top of the smoke guide plate 13, and the oil collection port 51 is far away from the bottom of the smoke guide plate 13. In this way, when the user cleans the integrated stove, he only needs to clean a small area above the oil collection port 51, which can improve the cleaning efficiency and further improve the aesthetics.

[0084] Optionally, please continue to refer to Figure 7 and Figure 8 The upper end of the smoke guide plate 13 connected to the oil guide channel 5 is extended with an oil guide plate 6, and the bottom end of the oil guide plate 6 extends obliquely into the oil guide channel 5. By providing the oil guide plate 6, all the oil flowing down from the smoke guide plate 13 can be guided into the oil guide channel 5, ensuring the oil discharge effect.

[0085] Optionally, see Figure 7 The upper end of the oil guide channel 5 connected to the smoking channel 11 is extended with a wind shield 7, and the bottom end of the wind shield 7 extends obliquely into the smoking channel 11. In the case where the wind shield 7 is not provided, the airflow entering the smoking channel 11 will flow from top to bottom along the smooth inner wall of the smoking channel 11 and form a "wind wall". The "wind wall" at the position of the oil discharge port 52 will block the liquid oil in the oil guide channel 5 from flowing into the smoking channel 11 from the oil discharge port 52. By providing the wind shield 7 at the oil discharge port 52, the formation of the "wind wall" can be disrupted, and a wind wall gap (such as a gap) can be formed at the oil discharge port 52. Figure 7As shown by the arrow in the middle), the liquid oil in the oil guide channel 5 is guided to flow from the oil discharge port 52 into the smoking channel 11.

[0086] Optionally, please continue to refer to Figure 7 The oil guide channel 5 is arranged in the air cooling channel 21. In this way, the air cooling channel 21 can also cool the oil smoke entering the oil guide channel 5, so as to prompt the oil stains attached to the inner surface of the channel wall of the oil guide channel 5 to condense into oil droplets in time to avoid the formation of wall accumulation.

[0087] Optionally, see Figure 7 and Figure 8 , the head 100 also includes a flow-blocking protrusion 81 protruding from the inner surface of the oil guide channel 5. By providing the flow-blocking protrusion 81 on the inner surface of the oil guide channel 5, the flow of gas in the oil guide channel 5 can be blocked, so as to reduce the flow of gas entering the oil guide channel 5 from the oil confluence port 51, thereby reducing the pressure loss in the smoking channel 11 and ensuring the exhaust effect; at the same time, since the oil confluence port 51 is opened toward the front, when the integrated stove is working, under the influence of the heat emitted by the gas stove 300, the air temperature in front of the smoke guide plate 13 is relatively high, which can prevent a large amount of high-temperature gas from entering the smoking channel 11 through the oil guide channel 5, thereby preventing a large amount of high-temperature gas from entering the smoking channel 11 and affecting the cooling effect on the channel wall of the smoking channel 11; in addition, reducing the high-temperature gas in front of the smoke guide plate 13 from entering the oil guide channel 5 can reduce the heat loss near the gas stove 300 during cooking to ensure the cooking effect. Preferably, the flow-blocking protrusion 81 is a rectangular parallelepiped structure, and the end face of the flow-blocking protrusion 81 is perpendicular to the flow direction of the smoke flow in the oil guide channel 5.

[0088] The number of the flow-blocking protrusions 81 can be set according to actual needs. Specifically, in this embodiment, a solution in which the number of the flow-blocking protrusions 81 is set is exemplarily provided.

[0089] Among them, a plurality of flow-blocking protrusions 81 can be arranged at intervals along the flow direction of the smoke flow in the oil guide channel 5. For details, please refer to Figure 8 Any two adjacent flow-blocking protrusions 81 are arranged alternately along the flow direction of the smoke flow in the oil-conducting channel 5. With such arrangement, after the smoke enters the oil-conducting channel 5 from the oil-converging port 51, it will meet the multiple flow-blocking protrusions 81 in sequence as the smoke flows, and change the flow direction under the obstruction of the flow-blocking protrusions 81, which plays a role in obstructing the flow of the airflow and avoiding the pressure loss in the smoking channel 11.

[0090] In addition, the plurality of flow-blocking protrusions 81 can also be arranged into a plurality of flow-blocking strips 8, and the plurality of flow-blocking strips 8 are arranged at intervals along the flow direction of the smoke flow in the oil guide channel 5, and each flow-blocking strip 8 includes a plurality of flow-blocking protrusions 81 arranged at intervals along the left and right directions of the integrated stove. Figure 8, any two adjacent blocking strips 8 are arranged in an interlaced manner along the flow direction of the smoke flow in the oil guide channel 5. In this way, a maze structure can be formed. Specifically, when the oil smoke enters the guide channel from the oil confluence port 51, the oil smoke first encounters the first blocking strip 8, and passes through the gaps between the multiple blocking protrusions 81 in the first blocking strip 8, and reaches the second blocking strip 8. Since the second blocking strip 8 and the first blocking strip 8 are interlaced with each other, the oil smoke will be blocked by the blocking protrusions 81 of the second blocking strip 8, and will be forced to bypass the blocking protrusions 81 from both sides and continue to flow to the third blocking strip 8. By analogy, the third blocking strip 8 and subsequent blocking strips 8 will also block the oil smoke to hinder the flow of airflow and avoid pressure loss in the smoking channel 11; and, through the collision between the blocking protrusions 81 and the oil smoke, the oil in the oil smoke will be helped to adhere to the blocking protrusions 81, which is convenient for the oil to be separated from the smoke and improves the oil smoke separation effect.

[0091] As an alternative solution, a labyrinth channel may be directly provided in the oil guiding channel 5 to replace the flow-blocking protrusion 81 . The labyrinth channel can also achieve the effect of blocking the airflow passing through the oil guiding channel 5 .

[0092] Optionally, see Figure 7 and Figure 8 The flow-blocking protrusion 81 is provided with a groove 811, and the groove 811 is connected to the smoking channel 11. In this way, by providing the groove 811, on the one hand, the total heat exchange area between the oil guide channel 5 and the air in the air cooling channel 21 can be increased, and at the same time, the flow-blocking protrusion 81 can directly exchange heat with the air in the air cooling channel 21, which can improve the condensation effect of the oil in the oil smoke contacting the flow-blocking protrusion 81, so as to further improve the oil smoke separation effect.

[0093] Preferably, the flow-blocking protrusion 81 and the oil-conducting channel 5 are integrally arranged. Such an arrangement can effectively reduce the number of parts. Specifically, the flow-blocking protrusion 81 can be formed on the oil-conducting channel 5 by a stamping process.

[0094] In this embodiment, the oil guide channel 5 includes a top wall 53 and a bottom wall 54 spaced apart along the up and down directions, and two side walls 55 spaced apart along the left and right directions of the integrated stove. The two side walls 55 are connected between the top wall 53 and the bottom wall 54. The oil guide channel 5 is surrounded by the top wall 53, the bottom wall 54 and the two side walls 55.

[0095] For details, please refer to Figure 7 and Figure 8In this embodiment, the flow-blocking protrusion 81 is protruding from the top wall 53 of the oil guide channel 5, and the flow-blocking protrusion 81 is spaced apart from the bottom wall 54 of the oil guide channel 5. In this way, there is a gap between the flow-blocking protrusion 81 and the bottom wall 54, which facilitates the oil to flow smoothly from the oil confluence port 51 to the oil discharge port 52 along the bottom wall 54. Of course, in other embodiments, the flow-blocking protrusion 81 can also be provided on the bottom wall 54 as needed, or the flow-blocking protrusion 81 can be provided on both the bottom wall 54 and the top wall 53.

[0096] Optionally, the area of ​​the oil confluence port 51 is S a , the area of ​​the oil discharge port 52 is S b , 0.5≤S a / S b ≤1, specifically, S a / S b The value of can be 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95 or 1. In this way, the area of ​​the oil discharge port 52 is smaller than the area of ​​the oil confluence port 51, which can reduce the flow rate of the gas in the oil guide channel 5 when passing through the oil discharge port 52, thereby reducing the external gas from entering the smoking channel 11 through the oil guide channel 5, so as to further reduce the pressure loss in the smoking channel 11; it can also further avoid the heat loss near the gas stove 300 during cooking; and further avoid the external high-temperature gas from entering the smoking channel 11 in large quantities, affecting the cooling effect on the channel wall of the smoking channel 11. Preferably, along the extension direction of the oil guide channel 5, the distance between the top wall 53 and the bottom wall 54 of the oil guide channel 5 gradually decreases from the oil confluence port 51 to the oil discharge port 52.

[0097] Optionally, the oil guide channel 5 includes an inlet section 56 near the oil confluence port 51, an outlet section 57 near the oil discharge port 52, and an intermediate section 58 connected between the inlet section 56 and the outlet section 57, and a plurality of flow-blocking protrusions 81 are all arranged in the intermediate section 58, and the curvature of the intermediate section 58, the curvature of the inlet section 56, and the curvature of the outlet section 57 are different. In this way, the oil guide channel 5 becomes tortuous, which can further hinder the flow of oil smoke inside it and further avoid the pressure loss in the smoking channel 11. At the same time, the tortuous oil guide channel 5 has a larger heat exchange area with the air in the air cooling channel 21 compared with the oil guide channel 5 extending in a straight direction, so as to further enhance the condensation effect of air on the oil smoke inside the oil guide channel 5. Specifically, in this embodiment, the curvature of the inlet section 56 is smaller than the curvature of the outlet section 57, and the intermediate section 58 is linear. In other embodiments, the curvatures of the inlet section 56, the intermediate section 58, and the outlet section 57 can also be set as needed.

[0098] Optionally, see Figure 2 and Figure 4The head 100 further includes a plurality of ventilation pipes 3 penetrating the oil guide channel 5 in the vertical direction, and both ends of the ventilation pipes 3 are connected to the air cooling channel 21. Due to the setting of the oil guide channel 5, the air flow of the air cooling channel 21 located at the upper and lower sides of the oil guide channel 5 will be hindered. By setting the ventilation pipes 3, the air at the upper and lower sides of the oil guide channel 5 can be guaranteed to flow normally to a certain extent, thereby ensuring a balanced cooling effect on the smoking channel 11; at the same time, the ventilation pipes 3 penetrate the oil guide channel 5, and the part of the ventilation pipes 3 located in the oil guide channel 5 can also hinder the flow of smoke in the oil guide channel 5, so as to further enhance the blocking effect on the smoke and further avoid the pressure loss of the smoking channel 11; in addition, the airflow in the air cooling channel 21 flows through the ventilation pipes 3, which can fully cool the ventilation pipes 3, thereby enhancing the oil smoke separation effect in the oil guide channel 5.

[0099] The ventilation pipe 3 can be made of metal material, such as hollow rivets, etc. The number of ventilation pipes 3 can also be set as needed. In this embodiment, a plurality of ventilation pipes 3 are provided, and the plurality of ventilation pipes 3 are spaced apart in the left-right direction.

[0100] Optionally, the ventilation pipe 3 is arranged at a position adjacent to the bottom end of the oil guiding channel 5 and away from the top end of the oil guiding channel 5, that is, the ventilation pipe 3 is adjacent to the oil discharge port 52. In this arrangement, the ventilation pipe 3 is close to the smoke exhaust fan 500 or the condensing fan, and the pressure loss of the negative pressure provided by the fan when it is transmitted to the ventilation pipe 3 is relatively small, which can ensure that the air in the upper sub-channel 23 enters the lower sub-channel 24 through the ventilation pipe 3. Specifically, the ventilation pipe 3 is arranged at the outlet section 57.
