[0049] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0050] Embodiment 1

[0051] See also Figures 1 to 6 The embodiment of the utility model provides a kitchen appliance, which may be a household appliance with a smoke-inhaling function such as a range hood, an integrated stove, or an integrated range hood. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collecting assembly, and the smoke collecting assembly includes a smoke collecting hood 210 and a wind shield 220. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collecting structure, and the smoke collecting structure includes a smoke collecting assembly and a wind guide assembly, and the smoke collecting assembly includes a smoke collecting hood 210 and a wind shield 220, and the wind guide assembly includes an air guide plate 310, and the air guide plate 310 is movably connected to the smoke collecting hood 210. The smoke collecting hood 210 supports the air guide plate 310, and the smoke collecting hood 210 is connected to the housing 100. A fan is provided in the housing 100 or in the smoke collecting hood 210, which is used to absorb oil smoke and discharge it through the smoke guide channel in the housing 100.

[0052] At least a portion of the front surface of the smoke hood 210 is recessed backward to form a accommodating cavity 2101, and an air inlet 2102 is provided on the bottom wall of the accommodating cavity 2101; the wind shield 220 is movably connected to the smoke hood 210, and an air inlet channel 201 is formed between the wind shield 220 and the air inlet 2102. The wind shield 220 can move between an open position and a closed position to open or close the air inlet channel 201. During the movement of the wind shield 220, at least a portion of the wind shield 220 does not exceed the front side of the accommodating cavity 2101.

[0053] The air inlet channel 201 is connected to the air inlet 2102, and the windshield 220 compresses the negative pressure at the air inlet 2102 toward the air inlet channel 201, effectively distributing and diffusing the negative pressure area from the air inlet 2102 to the periphery of the windshield 220, thereby increasing the negative pressure around the entire smoke collection area. At the same time, the oil smoke can reduce its speed after colliding with the windshield 220, effectively preventing the oil smoke from escaping from both sides, and significantly improving the smoking effect. The windshield 220 also cools and condenses the oil smoke entering the air inlet 2102, so that the oil stains in the oil smoke condense on the windshield 220, thereby increasing the oil stain adsorption and filtering effect.

[0054] The front surface of the smoke hood 210 extends downwardly from the front to the rear, providing space for the operator to operate on the cooker. In some embodiments, the accommodating cavity 2101 includes a first accommodating cavity and a second accommodating cavity arranged in a stepped manner, the front surface of the smoke hood 210 is recessed backward to form the first accommodating cavity, the upper surface of the bottom wall of the first accommodating cavity continues to be recessed backward to form the second accommodating cavity, and the air inlet 2102 is arranged on the bottom wall of the second accommodating cavity.

[0055] By providing the accommodating cavity 2101, it is possible to provide an accommodating space for the windshield 220, so as to avoid blocking the operating line of sight when the windshield 220 is opened. It can be that when the windshield 220 is in the open position, the entire windshield 220 does not exceed the front side of the accommodating cavity 2101. It can also be that when the windshield 220 is in the open position, the top of the windshield 220 exceeds the front side of the accommodating cavity 2101, and the bottom of the windshield 220 does not exceed the front side of the accommodating cavity 2101.

[0056] When the wind shield 220 is in the closed position, the air inlet channel 201 is closed. When the wind shield 220 moves from the closed position to the open position, the air inlet channel 201 is opened, and as the wind shield 220 moves to the open position, the air inlet area of ​​the air inlet channel 201 changes. When the air inlet channel 201 is in the closed state, in principle, the air inlet 2102 is completely blocked, but if the sealing effect of the air inlet 2102 is very good, noise is likely to occur during negative pressure suction, so when the air inlet channel 201 is in the closed state, the wind shield 220 blocks most of the air inlet area of ​​the air inlet 2102, and there may be a small gap.

[0057] The air inlet channel 201 is the space between the wind shield 220 and the air inlet 2102. Since the wind shield 220 can move relative to the air inlet 2102, the air inlet channel 201 is formed when there is a certain interval between the wind shield 220 and the air inlet 2102. When the wind shield 220 moves relative to the air inlet 2102, the air inlet area of ​​the air inlet channel 201 changes to adapt to different smoking conditions.

[0058] The wind shield 220 can move relative to the air inlet 2102, and can be movable in at least one of the front-to-back direction, the left-to-right direction, or the up-to-down direction. For example, it can move in the front-to-back direction, or it can move in both the front-to-back direction and the left-to-right direction, or it can move in both the front-to-back direction and the up-to-down direction, or it can move in both the left-to-right direction and the up-to-down direction, which are not listed here one by one.

[0059] Optionally, when the wind shield 220 is in the closed position, the wind shield 220 is located inside the accommodating cavity 2101 and fits against the front side of the air inlet 2102, or, the wind shield 220 is located outside the accommodating cavity 2101 and fits against the rear side of the air inlet 2102; or, the wind shield 220 is completely contained in the air inlet 2102.

[0060] In this embodiment, when the windshield 220 is in the closed position, the windshield 220 is located in the accommodating cavity 2101 and is attached to the front side of the air inlet 2102. Since the purpose of the windshield 220 in the closed position is to close the air inlet channel 201, the area of ​​the windshield 220 can be set to be larger than the area of ​​the air inlet 2102, that is, the width of the windshield 220 in the left-right direction is larger than the width of the air inlet 2102, and the height of the windshield 220 in the up-down direction is larger than the height of the air inlet 2102, so that the windshield 220 can completely cover the air inlet 2102 in the closed position to block the air inlet 2102. In the case where the area of ​​the windshield 220 is larger than the area of ​​the air inlet 2102, the windshield 220 cannot pass through the air inlet 2102, so when moving from the closed position to the open position, the windshield 220 can only move in front of the air inlet 2102. In the open position, the wind shield 220 is located in front of the air inlet 2102, so that the wind shield 220 is closer to the stove, thereby improving the smoking effect.

[0061] The windshield 220 is located in front of the air inlet 2102, and the windshield 220 and the inner wall of the accommodating cavity 2101 form a wind guide channel 202 that is connected to the air inlet channel 201. The gas enters the air inlet channel 201 from the wind guide channel 202 and then enters the air inlet 2102. The wind guide channel 202 guides the gas, and the windshield 220 compresses the negative pressure at the air inlet 2102 toward the air inlet channel 201, effectively distributing and diffusing the negative pressure area from the air inlet 2102 to the periphery of the windshield 220, so that the negative pressure radiates to the wind guide channel 202, thereby increasing the negative pressure around the entire smoke collection area.

[0062] The cross-sectional area of ​​the accommodating cavity 2101 gradually decreases from front to back, playing a role in guiding and compressing the air, increasing the wind speed and thus improving the smoking efficiency. The air inlet area of ​​the air guiding channel 202 changes as the wind shield 220 moves relative to the air inlet 2102, and can adapt to different smoking conditions.

[0063] In other embodiments, the width of the windshield 220 in the left-right direction is smaller than the width of the air inlet 2102, and the height of the windshield 220 in the up-down direction is greater than the height of the air inlet 2102. In the closed position, the windshield 220 is attached to the front side of the air inlet 2102. In the open position, the windshield 220 is located in front of the air inlet 2102, or at least part of the windshield 220 is located behind the air inlet 2102. That is, when moving from the closed position to the open position, the windshield 220 preferably moves to the front of the air inlet 2102, or may move to the rear of the air inlet 2102, or may be obliquely arranged in the air inlet 2102.

[0064] In other embodiments, the area of ​​the wind shield 220 is smaller than the area of ​​the air inlet 2102, and in the closed position, the wind shield 220 is completely contained in the air inlet 2102. When moving from the closed position to the open position, the wind shield 220 can move to the front of the air inlet 2102, can also move to the rear of the air inlet 2102, and can also be arranged in the air inlet 2102 at an angle.

[0065] If the wind shield 220 moves from the closed position to the open position, at least part of the wind shield 220 passes through the air inlet 2102, that is, during the movement of the wind shield 220, at least part of the wind shield 220 moves from the front side of the air inlet 2102 to the rear side of the air inlet 2102, or, at least part of the wind shield 220 moves from the rear side of the air inlet 2102 to the front side of the air inlet 2102.

[0066] In the open position, at least part of the wind shield 220 is located behind the air inlet 2102. Alternatively, in the open position, the top of the wind shield 220 is located in front of the air inlet 2102, and the bottom of the wind shield 220 is located behind the air inlet 2102; or, in the open position, the top of the wind shield 220 is located behind the air inlet 2102, and the bottom of the wind shield 220 is located in front of the air inlet 2102.

[0067] In this embodiment, in the closed position, the wind shield 220 is located in the accommodating cavity 2101 and is attached to the front side of the air inlet 2102. When moving from the closed position to the open position, the upper and lower ends of the wind shield 220 both move forward away from the air inlet 2102, so that the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the wind shield 220.

[0068] The air inlet ports of the air inlet channel 201 can be evenly distributed around the circumference of the wind shield 220, or can be unevenly distributed. In this embodiment, the air inlet area of ​​the air inlet channel 201 gradually decreases from top to bottom, that is, the air inlet port at the upper end of the air inlet channel 201 is large, and the air inlet port at the lower end of the air inlet channel 201 is small. The upper air inlet area is large, and the lower air inlet area is small, so that a negative pressure area is formed below the wind shield 220, thereby improving the smoking efficiency. In other embodiments, the air inlet area of ​​the air inlet channel 201 gradually increases from top to bottom; or, the air inlet area of ​​the air inlet channel 201 gradually decreases or increases from left to right.

[0069] See also Figure 3 and Figure 4 When moving from the closed position to the open position, the upper and lower ends of the windshield 220 both move in a direction away from the air inlet 2102, and the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the windshield 220. Exemplarily, the smoke collecting assembly further includes a driving member 230, one end of the driving member 230 is movably connected to the smoke collecting hood 210, the other end of the driving member 230 is movably connected to the windshield 220, the lower end of the windshield 220 is connected to the movable bracket 240, the movable bracket 240 is movably connected to the smoke collecting hood 210, and the driving member 230 can drive the windshield 220 to move. Among them, the movable connection can be hinged or connected by a pin shaft, which has a simple structure and is easy to implement.

[0070] In one embodiment, the driving member 230 itself is retractable, and the driving member 230 can be an electric push rod, a cylinder, a hydraulic cylinder, etc. The windshield 220 is fixedly connected to the movable bracket 240, and the windshield 220 is driven to move by the extension of the driving member 230. The rotation axis of the windshield 220 is the hinge axis of the movable bracket 240 and the smoke hood 210. In one embodiment, the driving member 230 rotates around the hinge axis between itself and the smoke hood 210, and the windshield 220 is hinged to the movable bracket 240. The windshield 220 is driven to move by the rotation of the driving member 230, which is equivalent to a four-bar linkage. Among them, the hinge axes all extend in the left and right directions of the smoke hood 210.

[0071] In this embodiment, the driving member 230 is retractable, and the wind shield 220 is fixedly connected to the movable bracket 240. Specifically, the bottom end of the driving member 230 is hinged to the smoke hood 210, the top end of the driving member 230 is hinged to the upper part of the wind shield 220, the movable bracket 240 is located at the bottom of the wind shield 220, the upper end of the movable bracket 240 is connected to the wind shield 220, and the lower end of the movable bracket 240 is hinged to the smoke hood 210. Figure 3 , when the wind shield 220 is in the closed position, the driving member 230 is in the retracted state; see Figure 4 , the driving member 230 extends outward, so that the wind shielding member 220 is in the open position.

[0072] The windshield 220 and the movable bracket 240 may be plug-in, snap-in, threaded or magnetically connected. For example, the movable bracket 240 is provided with a pin 241, the windshield 220 is provided with a first mounting plate 221, the first mounting plate 221 is provided with a socket 2211, the pin 241 is plugged with the socket 2211, and during the rotation of the movable bracket 240, the windshield 220 and the movable bracket 240 rotate synchronously. In order to ensure stability, at least two pins 241 may be provided, and at least two corresponding sockets 2211 may be provided.

[0073] Specifically, the lower end of the movable bracket 240 is rotatably connected to the smoke hood 210, and the pin 241 is arranged at the upper end of the movable bracket 240 and extends upward, so as to be inserted into the jack 2211 from bottom to top. A guide portion is arranged at the top of the pin 241 to guide the pin 241 to be inserted into the jack 2211.

[0074] The upper end of the movable bracket 240 is provided with a support leg 242, one end of the support leg 242 extends forward, and the pin 241 is located at the front end of the support leg 242 to avoid the smoke hood 210.

The windshield has a large windshield area, and can cool down and block the oil smoke entering the air inlet 2102, and some of the oil smoke can condense on the windshield. The edge of the windshield can be bent backward to form a flange 223, so that when the windshield blocks the air inlet 2102, the flange 223 abuts against the smoke hood 210.

The space between the wind shield 220 and the air inlet 2102 is the air inlet channel 201. The filter screen is arranged on the front side or the rear side of the wind shield 220. When the wind shield 220 is in the closed position, the wind shield 220 blocks the air inlet 2102. When the wind shield 220 is in the open position, the filter screen is attached to the front side or the rear side of the air inlet 2102, or the filter screen is completely contained in the air inlet 2102.

[0078] The smoke collecting assembly also includes an oil cup 250, which is arranged at the bottom of the smoke collecting hood 210 to facilitate the oil to flow into the oil cup 250. The surface of the windshield 220 forms an oil guide surface, which guides the oil to flow into the oil cup 250. The windshield 220 has a cooling and condensing effect on the oil smoke, so that the oil in the oil smoke condenses on the windshield 220, and the condensed oil flows downward along the windshield 220 into the oil cup 250. The windshield 220 plays an oil guide role, which can improve the cleanliness of the surface of the smoke collecting assembly.

[0079] The front surface of the smoke hood 210 in this embodiment is provided with a receiving cavity 2101, and at least part of the oil guide surface guides the oil to flow through the side wall of the receiving cavity 2101 and enter the oil cup 250. Specifically, the front surface and the rear surface of the windshield 220 can both play an oil guiding role and can serve as an oil guide surface.

[0080] See also Figure 3 When the wind shield 220 is in the closed position, the wind shield 220 is located in the accommodating chamber 2101 and is attached to the front side of the air inlet 2102. The accommodating chamber 2101 provides an accommodating space for the wind shield 220. The oil and dirt flowing down from the wind shield 220 flows through the side wall of the accommodating chamber 2101 and enters the oil cup 250. Figure 4When the wind shield 220 is in the open position, the bottom of the wind shield 220 is located in the accommodating cavity 2101 , and the oil flowing down from the wind shield 220 flows through the side wall of the accommodating cavity 2101 and enters the oil cup 250 .

[0081] In order to prevent the wind shield 220 from interfering with the smoke collecting hood 210 during movement, an avoidance groove or avoidance hole may be provided at a corresponding position of the smoke collecting hood 210 .

[0082] The smoke hood 210 includes at least two air inlets 2102, and a group of windshields 220 are provided corresponding to each air inlet 2102, and each windshield 220 moves independently or at least two windshields 220 are linked. When each windshield 220 moves independently, it can be synchronous movement or can move successively. In this embodiment, there are two air inlets 2102, corresponding to the left and right burners of the stove. A group of windshields 220 are provided corresponding to each air inlet 2102. The two air inlets 2102 can be both opened, both closed, or one opened and the other closed. Specifically, when only the left burner is used, the air inlet 2102 on the left is opened, when only the right burner is used, the air inlet 2102 on the right is opened, and when both burners are used, both air inlets 2102 are opened. The opening position of the windshield 220 can be adjusted by the stroke of the driving member 230, so the air inlet area of ​​the air inlet channel 201 can be adjusted according to actual needs.

[0083] When the air guide plate 310 is provided, the air guide plate 310 is movably connected to the smoke collecting hood 210. When the air guide plate 310 is opened, it flips forward. When the air guide plate 310 is closed, at least part of the air guide plate 310 shields the wind shield 220. The appearance is neat and the integrity is strong. When in use, the air guide plate 310 is first opened, so that the air guide plate 310 switches from the closed state to the open state. Figure 3 As shown, the wind deflector 310 is in an open state and the wind shield 220 is in a closed position. When at least two wind shields 220 are provided on the smoke hood 210, some or all of the wind shields 220 can be opened according to the use requirements. It can be that the wind deflector 310 is in an open state, one wind shield 220 is in an open position, and the other wind shield 220 is in a closed position. When not in use, the wind shield 220 can be closed first, and then the wind deflector 310; the wind shield 220 and the wind deflector 310 can also be closed at the same time.

[0084] In this embodiment, one wind guide plate 310 is provided. At least part of the wind guide plate 310 covers the wind shield 220, and the wind guide plate 310 may be completely covered by the wind shield 220, or part of the wind guide plate 310 may be covered by the wind shield 220. In other embodiments, two or more wind guide plates 310 may be provided. When two or more wind guide plates 310 are provided, at least one wind guide plate 310 may cover the wind shield 220, and the other wind guide plates 310 may not cover the wind shield 220.

[0085] When closed, the air guide plate 310 is retracted and covers behind the wind shield 220, covering at least part of the smoke hood 210. It can be that the air guide plate 310 covers the left and right edges of the smoke hood 210 in the left and right directions. After the air guide plate 310 is retracted, the front surface of the smoke collecting structure is a plane, that is, the air guide plate 310 is flush with part of the smoke hood 210, so as to ensure a neat appearance and strong integrity.

[0086] Specifically, the first driving mechanism drives the air guide plate 310 to move. When opening, the first driving mechanism is turned on, and after driving the air guide plate 310 to be fully opened, the driving member 230 drives the wind shield 220 to open. Among them, the first driving mechanism can adopt a conventional mechanism for driving the air guide plate 310 to flip. In some embodiments, the first driving mechanism includes a first push rod motor and a first connecting rod, one end of the first connecting rod is movably connected to the smoke hood 210, the other end of the first connecting rod is movably connected to the air guide plate 310, the body of the first push rod motor is movably connected to the smoke hood 210, and the push rod of the first push rod motor is movably connected to the rod body of the first connecting rod.

[0087] Embodiment 2

[0088] Figures 7 to 11 The second embodiment is shown, wherein the components identical or corresponding to the first embodiment are marked with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment are described. The difference is that when moving from the closed position to the open position, the wind shield 220 rotates around the first axis located at the bottom thereof, and the air inlet ports of the air inlet channel 201 are distributed at the upper part and the left and right sides of the wind shield 220. When opening, the upper end of the wind shield 220 moves forward away from the air inlet 2102, so that the cross-sectional shape of the air inlet channel 201 is V-shaped.

[0089] The plane where the windshield 220 is located forms an angle with the plane where the air inlet 2102 is located, and as the windshield 220 moves toward the open position, the angle gradually increases. In the open position, the angle formed by the plane where the windshield 220 is located and the plane where the air inlet 2102 is located is α, and the size of α can be set according to actual needs.

[0090] Exemplarily, the smoke collecting assembly further includes a driving member 230, one end of the driving member 230 is movably connected to the smoke collecting hood 210, the other end of the driving member 230 is movably connected to the wind shield 220, the bottom of the wind shield 220 is rotatably connected to the smoke collecting hood 210 around the first axis, and the driving member 230 can be extended to drive the wind shield 220 to move. The driving member 230 can be an electric push rod, a cylinder, a hydraulic cylinder, etc.

[0091] Specifically, the top of the driving member 230 is movably connected to the smoke hood 210, the bottom of the driving member 230 is movably connected to the upper part of the wind shield 220, and the bottom of the wind shield 220 can be directly connected to the smoke hood 210 or indirectly connected to the smoke hood 210. Exemplarily, a first mounting plate 221 is provided on the wind shield 220, and the first mounting plate 221 is bent and extended to form an arc hole 2212. A support shaft 270 is provided on the smoke hood 210, and the arc hole 2212 is sleeved on the support shaft 270, and the support shaft 270 extends along the first axis. In order to ensure stability, two first mounting plates 221 can be provided.

[0092] Exemplarily, a fixing bracket 260 is provided on the smoke hood 210, and the bottom of the wind shield 220 is rotatably connected to the fixing bracket 260 around the first axis. A first mounting plate 221 is provided on the wind shield 220, and the first mounting plate 221 is bent and extended to form an arc-shaped hole 2212. A support shaft 270 is provided on the fixing bracket 260, and the arc-shaped hole 2212 is sleeved on the support shaft 270, and the support shaft 270 extends along the first axis.

[0093] like Figure 7 As shown, the wind shield 220 is in the closed position, the wind deflector 310 is in the closed state, and the driving member 230 is in the retracted state. Figure 8 As shown, the wind deflector 310 is in an open state, the wind shield 220 is in a closed position, and the driving member 230 is in a retracted state. Fig. 9 As shown, the wind guide plate 310 is in an open state, and the driving member 230 extends outward, so that the wind shielding member 220 is in an open position.

[0094] In order to prevent the wind shield 220 from interfering with the smoke collecting hood 210 during movement, an avoidance groove or avoidance hole may be provided at a corresponding position of the smoke collecting hood 210 .

[0095] When two air inlets 2102 are provided on the smoke hood 210, a set of windshield members 220 is provided corresponding to each air inlet 2102. When the two windshield members 220 are both in the open position, the two air inlet channels 201 can be arranged in a ring shape around the periphery of the corresponding windshield member 220, or can be distributed on the upper part and left and right sides of the corresponding windshield member 220, or one air inlet channel 201 can be arranged in a ring shape around the periphery of the corresponding windshield member 220, and the other air inlet channel 201 can be distributed on the upper part and left and right sides of the corresponding windshield member 220.

[0096] Embodiment 3

[0097] Fig.12 and Fig.13 Embodiment 3 is shown, in which the parts identical or corresponding to those in Embodiment 1 are marked with the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences between Embodiment 3 and Embodiment 1 are described. The difference is that when the wind shield 220 is in the closed position, the wind shield 220 is located outside the accommodating cavity 2101 and fits against the rear side of the air inlet 2102. The front space of the smoke hood 210 is not occupied. Since the purpose of the wind shield 220 in the closed position is to close the air inlet channel 201, the area of ​​the wind shield 220 can be set to be larger than the area of ​​the air inlet 2102, so that the wind shield 220 can completely cover the air inlet 2102 in the closed position to block the air inlet 2102.

[0098] When the area of ​​the windshield 220 is larger than the area of ​​the air inlet 2102, the windshield 220 cannot pass through the air inlet 2102. Therefore, when moving from the closed position to the open position, the windshield 220 can only move to the rear of the air inlet 2102. In the open position, the windshield 220 is located behind the air inlet 2102. The windshield 220 is far away from the stove, which prolongs the path for the gas to reach the windshield 220. After passing through the air inlet 2102, the gas collides with the windshield 220. The windshield 220 compresses the negative pressure at the air inlet 2102 toward the air inlet channel 201, effectively distributing and diffusing the negative pressure area from the air inlet 2102 to the periphery of the windshield 220, and increasing the negative pressure around the entire smoke collecting chamber area. At the same time, the collision of oil smoke with the windshield 220 can reduce the oil smoke speed, making it easier to be adsorbed by the negative pressure, effectively preventing the oil smoke from escaping from both sides, and significantly improving the smoking effect.

[0099] In other embodiments, the width of the windshield 220 in the left-right direction is smaller than the width of the air inlet 2102, and the height of the windshield 220 in the up-down direction is greater than the height of the air inlet 2102. In the closed position, the windshield 220 is attached to the rear side of the air inlet 2102. In the open position, the windshield 220 is located in front of the air inlet 2102, or at least part of the windshield 220 is located behind the air inlet 2102. That is, when moving from the closed position to the open position, the windshield 220 preferably moves to the rear of the air inlet 2102, or may move to the front of the air inlet 2102, or may be obliquely arranged in the air inlet 2102.

[0100] In this embodiment, in the closed position, the wind shield 220 is located outside the accommodating cavity 2101 and is attached to the rear side of the air inlet 2102. When moving from the closed position to the open position, the upper and lower ends of the wind shield 220 both move to the rear away from the air inlet 2102, so that the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the wind shield 220.

[0101] See also Fig.13 When moving from the closed position to the open position, the upper and lower ends of the windshield 220 both move in a direction away from the air inlet 2102, and the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the windshield 220. Exemplarily, the smoke collecting assembly further includes a driving member 230, one end of the driving member 230 is movably connected to the smoke collecting hood 210, the other end of the driving member 230 is movably connected to the windshield 220, the lower end of the windshield 220 is connected to the movable bracket 240, the movable bracket 240 is movably connected to the smoke collecting hood 210, and the driving member 230 can drive the windshield 220 to move. The driving principle of the driving member 230 can be the same as that of the first embodiment, and will not be repeated here.

[0102] like Fig.12 As shown, the wind deflector 310 is in an open state, the wind shield 220 is in a closed position, and the driving member 230 is in an extended state. Fig.13 As shown, the wind guide plate 310 is in the open state, and the driving member 230 is retracted inwardly, so that the wind shielding member 220 is in the open position.

[0103] When two air inlets 2102 are provided on the smoke collecting hood 210, a set of windshield members 220 is provided corresponding to each air inlet 2102. When both windshield members 220 are in the open position, both windshield members 220 may be opened forward, both windshield members 220 may be opened backward, or one windshield member 220 may be opened forward and the other windshield member 220 may be opened backward.

[0104] Embodiment 4

[0105] Figures 14 to 16The fourth embodiment is shown, and the same or corresponding parts as the above embodiments are marked with corresponding reference numerals.

When opening, the upper end of the wind shield 220 moves to the rear away from the air inlet 2102.

[0106] The plane where the windshield 220 is located forms an angle with the plane where the air inlet 2102 is located, and as the windshield 220 moves toward the open position, the angle gradually increases. In the open position, the angle formed by the plane where the windshield 220 is located and the plane where the air inlet 2102 is located is α, and the size of α can be set according to actual needs.

The driving member 230 can be an electric push rod, a cylinder, a hydraulic cylinder, etc.

[0108] Specifically, the top of the driving member 230 is movably connected to the smoke hood 210, the bottom of the driving member 230 is movably connected to the upper part of the wind shield 220, and the bottom of the wind shield 220 is rotatably connected to the smoke hood 210 around the first axis. Exemplarily, the wind shield 220 is provided with a first mounting plate 221, the first mounting plate 221 is bent and extended to form an arc-shaped hole 2212, and the smoke hood 210 is provided with a support shaft 270, the arc-shaped hole 2212 is sleeved on the support shaft 270, and the support shaft 270 extends along the first axis.

[0111] When two air inlets 2102 are provided on the smoke hood 210, a set of windshield members 220 is provided corresponding to each air inlet 2102. When the two windshield members 220 are both in the open position, the air inlet ports of the two air inlet channels 201 can be arranged in a ring around the periphery of the corresponding windshield member 220, or can be distributed on the upper part and left and right sides of the corresponding windshield member 220, or the air inlet port of one air inlet channel 201 can be arranged in a ring around the periphery of the corresponding windshield member 220, and the air inlet port of the other air inlet channel 201 can be distributed on the upper part and left and right sides of the corresponding windshield member 220.
