[0047] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0048] Embodiment 1

[0049] See also Figures 1 to 8 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 collection component, and the smoke collection component includes a smoke hood, a windshield 221, and a filter 222. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection structure, and the smoke collection structure includes a smoke collection component and an air guide component, and the smoke collection component includes a smoke hood, a windshield 221, and a filter 222. The air guide component includes an air guide plate 310, and the air guide plate 310 is movably connected to the smoke hood. A fan is provided in the housing 100 or in the smoke hood to absorb oil smoke and discharge it through the smoke guide channel in the housing 100.

[0050] The front side of the smoke hood is provided with an air inlet 2102; the windshield 221 and the filter 222 are connected to form an integral structure 220, which is arranged at the air inlet 2102, and an air inlet channel 201 is formed between the windshield 221 and the air inlet 2102. The air inlet channel 201 is connected with the air inlet 2102, and the windshield 221 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 221, thereby increasing the negative pressure around the entire smoke collection area. At the same time, the oil smoke speed can be reduced after colliding with the windshield 221, making it easier to be adsorbed by the negative pressure, thereby significantly improving the smoking effect. The windshield 221 also cools and condenses the oil smoke, so that the oil in the oil smoke condenses on the windshield 221. The filter 222 is used to filter the oil smoke at the air inlet 2102. The combination of the two significantly improves the oil adsorption and filtering effect.

[0051] The air inlet channel 201 is the space between the air shield 221 and the air inlet 2102. When there is a certain distance between the air shield 221 and the air inlet 2102, the air inlet channel 201 is formed. When the air shield 221 moves relative to the air inlet 2102, the air inlet area of ​​the air inlet channel 201 changes.

[0052] The windshield 221 can be arranged at the front side of the filter 222, or at the rear side of the filter 222. When the windshield 221 is arranged at the front side of the filter 222, the oil smoke first contacts the windshield 221 to be decelerated and condensed, and is more convenient to be adsorbed by negative pressure. When the windshield 221 is arranged at the rear side of the filter 222, the oil smoke first contacts the filter 222, and then contacts the windshield 221 to be decelerated and condensed after being filtered. In this embodiment, the windshield 221 is arranged at the front side of the filter 222.

[0053] In this embodiment, the air inlet port of the air inlet channel 201 is arranged in a ring shape around the periphery of the wind shield plate 221. The air inlet port of the air inlet channel 201 is the distance between the circumferential edge of the wind shield plate 221 and the air inlet 2102.

[0054] The air inlet ports of the air inlet channel 201 can be evenly distributed or unevenly distributed around the circumference of the wind shield 221. 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 overall structure 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.

[0055] In this embodiment, the wind shield 221 is fixedly connected to the filter 222, so the air inlet space between the wind shield 221 and the filter 222 is fixed. In this embodiment, the air inlet space is arranged in a ring shape around the periphery of the wind shield 221, and the air inlet area of ​​the air inlet space gradually decreases from top to bottom.

[0056] The windshield 221 and the filter 222 may be connected by one or both of the following methods: plug-in connection, snap-on connection, threaded connection, or magnetic connection. Exemplarily, one end of the windshield 221 and the filter 222 are plugged in, and the other end is magnetically connected. In other embodiments, the windshield 221 and the filter 222 are movably connected, and the air inlet area of ​​the air inlet channel 201 is adjustable. Alternatively, a drive assembly may be provided between the windshield 221 and the filter 222 to drive the windshield 221 and the filter 222 to move relative to each other, and the drive assembly may be a conventional electric push rod, a cylinder, a hydraulic cylinder, or the like.

[0057] The smoke collecting assembly also includes a driving member 230, which is connected to the overall structure 220 to drive the overall structure 220 to move relative to the air inlet 2102. For example, one end of the driving member 230 is movably connected to the smoke collecting hood, the other end of the driving member 230 is movably connected to the overall structure 220, the lower end of the overall structure 220 is connected to the movable bracket 240, and the movable bracket 240 is movably connected to the smoke collecting hood. Alternatively, one end of the driving member 230 is movably connected to the smoke collecting hood, the other end of the driving member 230 is movably connected to the overall structure 220, and the bottom of the overall structure 220 is rotatably connected to the smoke collecting hood around the first axis. The driving member 230 itself is retractable and can be an electric push rod, a cylinder, a hydraulic cylinder, etc. Among them, the movable connection can be hinged or connected by a pin shaft, which has a simple structure and is easy to implement. The movable connection can also be both relatively slidable and relatively rotatable.

[0058] The overall structure 220 moves relative to the air inlet 2102 so that the wind shield 221 can switch between a use state and a non-use state. In the non-use state, the wind shield 221 closes the air inlet 2102, so that the air inlet channel 201 is closed and cannot communicate with the outside world and the air inlet 2102; in the use state, the air inlet channel 201 is opened, and the air inlet 2102 communicates with the outside world through the air inlet channel 201. Specifically, in the use state, the wind shield 221 is located in front of the air inlet 2102; or at least part of the wind shield 221 is located behind the air inlet 2102.

[0059] Since the purpose of the wind shield 221 in the non-use state is to close the air inlet 2102, the area of ​​the wind shield 221 can be set to be larger than the area of ​​the air inlet 2102, that is, the width of the wind shield 221 in the left-right direction is larger than the width of the air inlet 2102, and the height of the wind shield 221 in the up-down direction is larger than the height of the air inlet 2102, so that the wind shield 221 can completely cover the air inlet 2102 in the non-use state to close the air inlet 2102. In the case where the area of ​​the wind shield 221 is larger than the area of ​​the air inlet 2102, the wind shield 221 cannot pass through the air inlet 2102, so when switching from the non-use state to the use state, the wind shield 221 can only move in front of or behind the air inlet 2102, so that in the use state, the wind shield 221 is located in front of or behind the air inlet 2102.

[0060] In some embodiments, in the non-use state, the wind shield 221 is attached to the front side or the rear side of the air inlet 2102. When switching from the non-use state to the use state, the wind shield 221 moves to the front or rear side of the air inlet 2102. In the use state, the wind shield 221 is located in front of or behind the air inlet 2102.

[0061] In some embodiments, the width of the windshield 221 in the left-right direction is smaller than the width of the air inlet 2102, and the height of the windshield 221 in the up-down direction is greater than the height of the air inlet 2102. In the non-use state, the windshield 221 is attached to the front side of the air inlet 2102. In the use state, the windshield 221 is located in front of the air inlet 2102; or, at least part of the windshield 221 is located behind the air inlet 2102. That is, when switching from the non-use state to the use state, the windshield 221 preferably moves to the front of the air inlet 2102, or it can move to the rear of the air inlet 2102, or it can be obliquely arranged in the air inlet 2102.

[0062] In other embodiments, the area of ​​the wind shield 221 is smaller than the area of ​​the air inlet 2102, and in the non-use state, the wind shield 221 is completely contained in the air inlet 2102. When switching from the non-use state to the use state, the wind shield 221 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 obliquely arranged in the air inlet 2102.

[0063] If the wind shield 221 is switched from the non-use state to the use state, at least part of the wind shield 221 passes through the air inlet 2102, that is, during the movement of the wind shield 221, at least part of the wind shield 221 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 221 moves from the rear side of the air inlet 2102 to the front side of the air inlet 2102.

[0064] In the use state, at least part of the windshield 221 is located behind the air inlet 2102, so that the oil on the windshield 221 flows to the rear of the air inlet 2102. Alternatively, the top of the windshield 221 is located in front of the air inlet 2102, and the bottom of the windshield 221 is located behind the air inlet 2102.

[0065] The filter 222 may be located in front of or behind the air inlet 2102 or may be completely contained within the air inlet 2102 . The filter 222 may be attached to the front side or the rear side of the air inlet 2102 .

[0066] The filter 222 is completely contained in the air inlet 2102. The width of the filter 222 in the left-right direction is smaller than the width of the air inlet 2102, and the height of the filter 222 in the up-down direction is smaller than the height of the air inlet 2102. During the movement of the filter 222, the filter 222 can move forward to the front of the air inlet 2102, can move backward to the air inlet 2102, or can be obliquely inserted into the air inlet 2102.

[0067] During the movement of the wind shield 221 relative to the air inlet 2102, at least part of the filter 222 passes through the air inlet 2102, that is, at least part of the filter 222 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 filter 222 moves from the rear side of the air inlet 2102 to the front side of the air inlet 2102.

[0068] During the movement of the overall structure 220 relative to the air inlet 2102, it is possible that the filter 222 is located behind the air inlet 2102 and the wind shield 221 is located in front of the air inlet 2102; it is also possible that the filter 222 is located behind the air inlet 2102 and the wind shield 221 is attached to the front side of the air inlet 2102; it is also possible that the filter 222 is completely accommodated in the air inlet 2102 and the wind shield 221 is located in front of the air inlet 2102; it is also possible that at least part of the filter 222 is located in front of the air inlet 2102, and the wind shield 221 is located in front of the air inlet 2102.

[0069] Preferably, the windshield 221 is located in front of the air inlet 2102, and the filter 222 is completely contained in the air inlet 2102. The oil smoke first contacts the windshield 221 to be decelerated and condensed, then passes through the filter 222 to be filtered, and finally enters the smoke collecting hood.

[0070] In this embodiment, the smoke collecting hood includes a first smoke collecting hood 211 and a second smoke collecting hood 212, and the second smoke collecting hood 212 is movably connected to the first smoke collecting hood 211. In this embodiment, the first smoke collecting hood 211 is fixedly arranged, and the second smoke collecting hood 212 is movably connected to the first smoke collecting hood 211 and can move between an open position and a closed position. An air inlet 2102 is provided on the front side of the second smoke collecting hood 212. In the open position, the air inlet 2102 is closer to the stove.

[0071] In other embodiments, the first smoke collecting hood 211 and the second smoke collecting hood 212 are both movably arranged relative to the smoke collecting hood rear plate, and the smoke collecting hood rear plate can be fixed on a wall or a cabinet. The first smoke collecting hood 211 and the second smoke collecting hood 212 can move independently or in conjunction.

[0072] In this embodiment, the first smoke hood 211 is fixedly arranged and has a smoke collecting cavity with a front opening, and the second smoke hood 212 is movably arranged at the opening of the smoke collecting cavity, that is, the first smoke hood 211 is sleeved on the periphery of the second smoke hood 212, and the front side of the second smoke hood 212 is provided with an air inlet 2102 connected to the smoke collecting cavity, and the second smoke hood 212 can move between an open position and a closed position. In other embodiments, the second smoke hood 212 is sleeved on the periphery of the first smoke hood 211, the first smoke hood 211 has a smoke collecting cavity with a front opening, and the front side of the second smoke hood 212 is provided with an air inlet 2102, and the air inlet 2102 is connected to the smoke collecting cavity.

[0073] In the open position, the second smoke hood 212 protrudes from the front side of the first smoke hood 211, so that the second smoke hood 212 and the first smoke hood 211 form a larger smoke collection area, and the air inlet 2102 on the second smoke hood 212 is closer to the stove, which improves the smoke collection effect. When closed, the second smoke hood 212 is located inside the first smoke hood 211, with a neat appearance and strong integrity. Alternatively, when the second smoke hood 212 is in the open position, the front surface of the second smoke hood 212 is flush with the front surface of the first smoke hood 211.

[0074] The overall structure 220 and the second smoke collecting hood 212 are driven separately. During the movement of the overall structure 220 relative to the air inlet 2102, the overall structure 220 and the second smoke collecting hood 212 move synchronously on at least a portion of the path; and / or, the overall structure 220 and the second smoke collecting hood 212 move relative to each other on at least a portion of the path.

[0075] In this embodiment, when the second smoke hood 212 is in the closed position, the filter 222 is located behind the air inlet 2102, the top of the windshield 221 is located in front of the air inlet 2102, and the bottom of the windshield 221 is located inside the air inlet 2102 or at the rear of the air inlet 2102, so that the oil on the windshield 221 can flow into the first smoke hood 211. In other embodiments, when the second smoke hood 212 is in the closed position, the filter 222 is located behind the air inlet 2102, and the windshield 221 is attached to the front of the air inlet 2102. In other embodiments, when the second smoke hood 212 is in the closed position, the filter 222 is located behind the air inlet 2102, and the windshield 221 is located in front of the air inlet 2102.

[0076] When the second smoke hood 212 moves from the closed position to the open position, the wind shield 221 switches from the use state to the non-use state. When the second smoke hood 212 is in the open position, the wind shield 221 can switch between the use state and the non-use state. For the case where a plurality of air inlets 2102 are provided on the second smoke hood 212, some or all of the air inlets 2102 can be opened as needed. In the non-use state, the wind shield 221 closes the air inlet 2102, and in the use state, the wind shield 221 is located in front of the air inlet 2102.

[0077] In this embodiment, when the second smoke hood 212 is in the open position and the wind shield 221 is in use, the filter 222 is completely contained in the air inlet 2102. In other embodiments, when the second smoke hood 212 is in the open position and the wind shield 221 is in use, the filter 222 is attached to the rear side of the air inlet 2102.

[0078] In this embodiment, the integral structure 220 is movably connected to the first smoke collecting hood 211. Therefore, when the windshield 221 switches between the non-use state and the use state, the windshield 221 moves relative to the first smoke collecting hood 211, and the windshield 221 and the second smoke collecting hood 212 may move synchronously or relatively.

[0079] In this embodiment, when the overall structure 220 moves relative to the air inlet 2102, the upper end and the lower end of the overall structure 220 both move away from or towards the air inlet 2102. That is, when the wind shield 221 switches from the non-use state to the use state, the upper end and the lower end of the overall structure 220 both move away from the air inlet 2102, and when the wind shield 221 switches from the use state to the non-use state, the upper end and the lower end of the overall structure both move towards the air inlet 2102.

Among them, the movable connection can be hinged or connected by a pin shaft, which has a simple structure and is easy to implement. The movable connection can also be relatively slidable and relatively rotatable.

[0081] 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 overall structure 220 is fixedly connected to the movable bracket 240, and the overall structure 220 is driven to move by the extension of the driving member 230. The rotation axis of the overall structure 220 is the hinge axis of the movable bracket 240 and the first smoke hood 211. In one embodiment, the driving member 230 rotates around the hinge axis between itself and the first smoke hood 211, and the overall structure 220 is hinged to the movable bracket 240. The overall structure 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 extend along the left and right directions of the first smoke hood 211.

[0082] In this embodiment, the driving member 230 itself is retractable, and the overall structure 220 is fixedly connected to the movable bracket 240. Specifically, the bottom end of the driving member 230 is hinged to the first smoke collecting hood 211, the top end of the driving member 230 is hinged to the upper part of the filter screen 222, the movable bracket 240 is located at the bottom of the overall structure 220, the upper end of the movable bracket 240 is connected to the overall structure 220, and the lower end of the movable bracket 240 is hinged to the first smoke collecting hood 211.

[0083] The movable bracket 240 connects the windshield 221 and the filter 222, so that the windshield 221 and the filter 222 are connected to form an integral structure 220. For example, the movable bracket 240 is provided with a first pin 241, the windshield 221 is provided with a first mounting plate 2211, the first mounting plate 2211 is provided with a first socket, and the first pin 241 is plugged into the first socket.

[0087] A magnetic seat 260 is provided between the windshield 221 and the filter 222, and the windshield 221 and the filter 222 are connected through the magnetic seat 260. The provision of the magnetic seat 260 ensures that the air inlet space between the windshield 221 and the filter 222 is fixed. It can be that one end of the magnetic seat 260 is magnetically attracted to the windshield 221, and the other end of the magnetic seat 260 is magnetically attracted to the filter 222; it can also be that one end of the magnetic seat 260 is fixed to the windshield 221, and the other end of the magnetic seat 260 is magnetically attracted to the filter 222; it can also be that one end of the magnetic seat 260 is magnetically attracted to the windshield 221, and the other end of the magnetic seat 260 is fixed to the filter 222.

[0088] See also Figure 3 When the second smoke hood 212 is in the closed position, the filter 222 is located behind the air inlet 2102, the top of the windshield 221 is suspended in front of the air inlet 2102, and the bottom of the windshield 221 is located behind the air inlet 2102, so that all the oil on the windshield 221 can be introduced into the first smoke hood 211 without oil dripping. When the second smoke hood 212 is opened, the driving member 230 gradually extends. Figure 4When the second smoke collecting hood 212 is in the open position, the windshield 221 is attached to the front side of the air inlet 2102, and the filter 222 is located behind the air inlet 2102. When the windshield 221 is switched from the non-use state to the use state, the driving member 230 continues to extend. Figure 5 After the driving member 230 extends outward, the wind shield 221 is located in front of the air inlet 2102, and the filter screen 222 is completely accommodated in the air inlet 2102.

[0089] When shutting down, the driving member 230 retracts and drives the overall structure 220 to return to the position where the wind shield 221 is attached to the front side of the air inlet 2102, and the filter 222 is located behind the air inlet 2102. As the second smoke hood 212 is closed, the driving member 230 continues to retract. When the second smoke hood 212 is retracted into the first smoke hood 211, the overall structure 220 returns to its initial position.

[0090] The smoke collecting assembly also includes an oil cup 250, which is arranged at the bottom of the smoke collecting hood to facilitate the flow of oil into the oil cup 250. The surface of the windshield 221 and / or the filter 222 forms an oil guide surface, which guides the oil to flow into the oil cup 250. The windshield 221 has a cooling and condensing effect on the oil smoke, so that the oil in the oil smoke condenses on the windshield 221; the filter 222 has a filtering effect on the oil smoke, and part of the oil smoke condenses on the filter 222 during the filtering process; the condensed oil flows downward along the windshield 221 and / or the filter 222 into the oil cup 250, and the oil guide surface plays an oil guide role, which can improve the cleanliness of the surface of the smoke collecting assembly. The front and rear surfaces of the windshield 221 can be used as oil guide surfaces. The front and rear surfaces of the filter 222 can be used as oil guide surfaces.

[0091] In this embodiment, a receiving cavity 2101 is provided on the front surface of the second smoke collecting hood 212, and an air inlet 2102 is provided on the bottom wall of the receiving cavity 2101; when the wind shield 221 is located in front of the air inlet 2102, the outer peripheral edge of the wind shield 221 and the inner wall of the receiving cavity 2101 form an air guide channel 202 connected to the air inlet channel 201. The gas enters the air inlet channel 201 from the air guide channel 202, and the air guide channel 202 guides the gas. The wind shield 221 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 wind shield 221, so that the negative pressure radiates to the air guide channel 202, thereby increasing the negative pressure around the entire smoke collecting area.

[0092] In this embodiment, the second smoke hood 212 is in the open position, the filter 222 is contained in the air inlet 2102, the air inlet channel 201 between the wind shield 221 and the air inlet 2102 is open, and the outer peripheral edge of the wind shield 221 and the inner wall of the accommodating chamber 2101 form an air guide channel 202 connected to the air inlet channel 201. The gas enters the air inlet channel 201 from the air guide channel 202, passes through the filter 222, and enters the first smoke hood 211. The air guide channel 202 is the distance between the outer peripheral edge of the wind shield 221 and the inner wall of the accommodating chamber 2101.

[0093] The cross-sectional area of ​​the accommodating cavity 2101 gradually decreases from front to back, playing the role of guiding wind and collecting pressure, increasing wind speed and thus improving smoking efficiency. The air inlet area of ​​the air guide channel 202 changes as the wind shield 221 moves relative to the air inlet 2102, which can adapt to different smoking conditions.

[0094] During the movement of the overall structure 220, at least part of the overall structure 220 does not extend beyond the front side of the accommodating cavity 2101. By providing the accommodating cavity 2101, it is possible to provide an accommodating space for the overall structure 220, thereby preventing the overall structure 220 from blocking the operating line of sight when the overall structure 220 is opened. Specifically, the front surface of the second smoke hood 212 extends downwardly from the front to the rear, providing space for the operator to operate on the cooker.

[0095] At least part of the oil guide surface guides the oil to flow through the side wall of the accommodating cavity 2101 and enter the oil cup 250. Figure 4 , the second smoke collecting hood 212 is in the open position, the wind shield 221 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 221, and the oil stains flowing down from the wind shield 221 flow through the side wall of the accommodating chamber 2101 and enter the oil cup 250. Figure 5 When the wind shield 221 is in use, the wind shield 221 is located in front of the air inlet 2102, and the bottom of the wind shield 221 is located in the accommodating chamber 2101. The oil flowing down from the wind shield 221 flows through the side wall of the accommodating chamber 2101 and enters the oil cup 250; the filter screen 222 is completely accommodated in the air inlet 2102, and the oil flowing down from the filter screen 222 flows through the side wall of the accommodating chamber 2101 and enters the oil cup 250.

[0096] In order to prevent the overall structure 220 from interfering with the second smoke collecting hood 212 during movement, an avoidance groove or avoidance hole may be provided at a corresponding position of the second smoke collecting hood 212 .

In this embodiment, two air inlets 2102 are provided, corresponding to the left and right burners of the stove. A group of integral structures 220 is provided corresponding to each air inlet 2102. The air inlet channels 201 corresponding to the two air inlets 2102 can be both opened, or both closed, or one opened and the other closed. Specifically, when only the left burner is used, the air inlet channel 201 on the left is opened, that is, the wind shield 221 on the left is located in front of the air inlet 2102, and the wind shield 221 on the right is attached to the front side of the air inlet 2102; when only the right burner is used, the air inlet channel 201 on the right is opened, and when both burners are used, both air inlet channels 201 are opened. The position of the integral structure 220 can be adjusted by the stroke of the driving member 230.

[0098] The moving path of the second smoke hood 212 can be a straight line or a curve; in the present embodiment, the second smoke hood 212 rotates around a fixed axis, and the second smoke hood 212 flips forward while approaching the stove below. Specifically, the bottom end of the second smoke hood 212 is rotatably connected to the first smoke hood 211. A pin or a rotating shaft is provided at the rotating connection. In other embodiments, the second smoke hood 212 can move along a first straight line, and the first straight line extends downwardly from the back to the front, so that the second smoke hood 212 moves downward while protruding from the front side of the first smoke hood 211, approaching the stove below.

[0099] When the air guide plate 310 is provided, the air guide plate 310 is movably connected to the first smoke collecting hood 211. The air guide plate 310 flips forward when opened, and at least a part of the air guide plate 310 covers the overall structure 220 when closed, so that the appearance is neat and the integrity is strong. When in use, the air guide plate 310 and the second smoke collecting hood 212 can be opened simultaneously or successively. Figure 4 As shown, the air guide plate 310 is in an open state, the second smoke hood 212 is in an open position, and the wind shield 221 is in a non-use state. When at least two integral structures 220 are provided, part or all of the integral structures 220 can be opened according to the use requirements. It can be that the air guide plate 310 is in an open state, the second smoke hood 212 is in an open position, one wind shield 221 is in a non-use state, and the other wind shield 221 is in a use state. When not in use, the second smoke hood 212 and the wind shield 221 can be closed simultaneously or successively, and then the air guide plate 310 can be closed; or the three can be closed at the same time.

[0100] In this embodiment, one wind deflector 310 is provided. At least part of the wind deflector 310 shields the overall structure 220, and the wind deflector 310 may shield the overall structure 220 in its entirety or partially. In other embodiments, two or more wind deflectors 310 may be provided. When two or more wind deflectors 310 are provided, at least one wind deflector 310 may shield the overall structure 220, and the remaining wind deflectors 310 may not shield the overall structure 220.

[0101] When closed, the air guide plate 310 is retracted and blocks the overall structure 220, and at least covers a portion of the second smoke collecting hood 212. It can be that the air guide plate 310 covers the left and right edges of the second smoke collecting hood 212 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 a portion of the first smoke collecting hood 211, so as to ensure a neat appearance and strong integrity.

[0102] The air guide plate 310 and the second smoke collecting hood 212 can both move relative to the first smoke collecting hood 211. The two can move independently of each other, share a driving mechanism, or be linked to each other. The driving mechanism can adopt a conventional mechanism for driving the air guide plate 310 and the second smoke collecting hood 212 to flip, which will not be described in detail here.

[0103] Embodiment 2

[0104] Figures 9 to 15 Embodiment 2 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 2 and Embodiment 1 are described. The difference is that the overall structure 220 is movably connected to the second smoke hood 212. Therefore, when the windshield 221 is switched between the non-use state and the use state, the windshield 221 and the second smoke hood 212 move relative to each other. In the process of opening the second smoke hood 212, the windshield 221 and the second smoke hood 212 may move synchronously or relative to each other.

[0105] In the non-use state, the windshield 221 is attached to the front side of the air inlet 2102, and the filter 222 is located behind the air inlet 2102. When switching from the non-use state to the use state, the windshield 221 moves toward the front of the air inlet 2102, and the filter 222 moves forward accordingly. In the use state, the windshield 221 is located in front of the air inlet 2102, and the filter 222 is accommodated in the air inlet 2102.

[0106] In this embodiment, the air inlet ports of the air inlet channel 201 are distributed on the upper part and the left and right sides of the wind shield 221, and the cross-sectional shape of the air inlet channel 201 is V-shaped. The air inlet area of ​​the air inlet channel 201 gradually decreases from top to bottom. 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 overall structure 220, thereby improving the smoking efficiency.

[0107] The plane where the wind shield plate 221 is located and the plane where the air inlet 2102 is located form an angle α, and the value of α can be set according to actual needs.

[0108] In this embodiment, when the overall structure 220 moves relative to the air inlet 2102, the overall structure 220 rotates around the first axis located at the lower part thereof relative to the air inlet 2102. When the wind shield 221 switches from the non-use state to the use state, the upper end of the overall structure 220 moves forward away from the air inlet 2102.

[0109] Exemplarily, the smoke collecting assembly further includes a driving member 230, one end of the driving member 230 is movably connected to the first smoke collecting hood 211, the other end of the driving member 230 is movably connected to the filter screen 222, the bottom of the overall structure 220 is rotatably connected to the second smoke collecting hood 212 around the first axis, and the driving member 230 can be extended to drive the overall structure 220 to move. The driving member 230 can be an electric push rod, a cylinder, a hydraulic cylinder, etc.

[0110] Specifically, the top of the driving member 230 is hinged to the first smoke hood 211, the bottom of the driving member 230 is hinged to the upper part of the filter 222, and the bottom of the overall structure 220 can be directly connected to the second smoke hood 212, or indirectly connected to the second smoke hood 212. Exemplarily, a third mounting plate 2212 is provided on the windshield 221, and the third mounting plate 2212 is bent and extended to form a first arc-shaped hole, and a support shaft 270 is provided on the filter 222, and the first arc-shaped hole is sleeved on the support shaft 270, and a fourth mounting plate 2121 is provided on the second smoke hood 212, and the fourth mounting plate 2121 is bent and extended to form a second arc-shaped hole, and the second arc-shaped hole is sleeved on the support shaft 270. The support shaft 270 extends along the first axis.

[0111] It may be that a limiting member is provided on the second smoke hood 212. When the second smoke hood 212 is in the open position, as the driving member 230 extends, the wind shield 221 and the filter 222 rotate forward at the same time. When the wind shield 221 or the filter 222 abuts against the limiting member, it limits the overall structure 220, so that the wind shield 221 remains in use.

[0112] like Fig.10As shown, the second smoke collecting hood 212 is in a closed position, the wind guide plate 310 is in a closed state, the wind shield 221 is located in front of the air inlet 2102, and the filter 222 is accommodated in the air inlet 2102.

[0113] When the machine is turned off, the driving member 230 retracts to drive the wind shield 221 back to a non-use state, and then the wind guide plate 310 is retracted, driving the second smoke hood 212 to be retracted into the first smoke hood 211. During the retraction of the second smoke hood 212, the driving member 230 continues to retract to keep the wind shield 221 in a non-use state.

[0114] In order to prevent the wind shield 221 from interfering with the second smoke collecting hood 212 during movement, an avoidance groove or avoidance hole may be provided at a corresponding position of the second smoke collecting hood 212 .

[0115] When two air inlets 2102 are provided on the second smoke collecting hood 212, a group of integral structures 220 are provided corresponding to each air inlet 2102. The two air inlet channels 201 may be arranged in a ring shape around the periphery of the corresponding windshield 221, or may be distributed on the upper part and left and right sides of the corresponding windshield 221, or one air inlet channel 201 may be arranged in a ring shape around the periphery of the corresponding windshield 221, and the other air inlet channel 201 may be distributed on the upper part and left and right sides of the corresponding windshield 221.

[0116] In other embodiments, the integral structure 220 is fixedly connected to the first smoke hood 211, and during the movement of the second smoke hood 212, the integral structure 220 and the air inlet 2102 move relative to each other. Alternatively, the first smoke hood 211 includes a smoke hood rear plate, and the integral structure 220 is fixedly connected to the smoke hood rear plate.

When the second smoke collecting hood 212 moves from the closed position to the open position, the wind shield 221 remains in front of the air inlet 2102, and the filter 222 is attached to the air inlet 2102 from the front of the air inlet 2102 or contained in the air inlet 2102.

[0118] In other embodiments, the smoke hood is fixedly arranged, and the overall structure 220 is fixedly connected to the smoke hood; or, at least one of the wind shield 221 and the filter 222 is movable relative to the smoke hood.
