[0056] See also Figures 1 to 8, an embodiment of the utility model provides a kitchen appliance, which may be a household appliance with a smoking function, such as a side-suction range hood, an integrated stove, and an integrated range hood. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection assembly 10, the smoke collection assembly 10 includes a fixed smoke collection hood 11, a movable smoke collection hood 12, and a wind shield assembly 13, and the movable smoke collection hood 12 is movably connected to the fixed smoke collection hood 11. In some embodiments, the kitchen appliance includes a housing 100 and a smoke collection structure, the smoke collection structure includes a smoke collection assembly 10 and a wind guide assembly 20, the smoke collection assembly 10 includes a fixed smoke collection hood 11, a movable smoke collection hood 12, and a wind shield assembly 13, and the movable smoke collection hood 12 is movably connected to the fixed smoke collection hood 11.

[0057] The fixed smoke hood 11 has a smoke collecting cavity with a front opening, and the movable smoke hood 12 is movably arranged at the opening of the smoke collecting cavity. The front surface of the movable smoke hood 12 is provided with a first smoke inlet 121 connected to the smoke collecting cavity. When opened, the movable smoke hood 12 protrudes from the front side of the fixed smoke hood 11. In this embodiment, the wind shield assembly 13 is arranged on the movable smoke hood 12 and blocks the first smoke inlet 121, and an air inlet channel 130 connected to the first smoke inlet 121 is defined between the wind shield assembly 13 and the movable smoke hood 12. In other embodiments, the wind shield assembly 13 is arranged on the fixed smoke hood 11 and blocks the first smoke inlet 121, and an air inlet channel 130 connected to the first smoke inlet 121 is defined between the wind shield assembly 13 and the movable smoke hood 12.

[0058] The wind shield assembly 13 is fixedly or movably connected to the movable smoke collecting hood 12; or, the wind shield assembly 13 is fixedly or movably connected to the fixed smoke collecting hood 11. When fixedly connected, the structure is stable. When movably connected, the size of the air inlet channel 130 is easy to adjust.

[0059] In some embodiments, the fixed smoke hood 11 includes a smoke hood rear plate, and the wind shield assembly 13 is fixedly connected or movably connected to the smoke hood rear plate. In some embodiments, the wind shield assembly 13 is movably connected to the fixed smoke hood 11; during the movement of the movable smoke hood 12, the wind shield assembly 13 and the movable smoke hood 12 move synchronously on at least part of the path; and / or, on at least part of the path, the wind shield assembly 13 and the movable smoke hood 12 have relative movement.

[0060] When opened, the movable smoke hood 12 protrudes from the front side of the fixed smoke hood 11, so that the movable smoke hood 12 and the fixed smoke hood 11 form a larger smoke collection area, and the first smoke inlet 121 on the movable smoke hood 12 is closer to the stove, improving the smoking effect. The wind shield component 13 can cool down and block and slow down the oil smoke entering the first smoke inlet 121, so that the oil smoke can be more easily adsorbed by negative pressure. When closed, the movable smoke hood 12 is located inside the fixed smoke hood 11, with a neat appearance and strong integrity.

[0061] The air inlet channel 130 is the space between the windshield component 13 and the first smoke inlet 121. There is a certain interval between the windshield component 13 and the first smoke inlet 121, so that the oil smoke can enter the first smoke inlet 121, that is, the air inlet channel 130 connected with the first smoke inlet 121 is formed. The air inlet channel 130 is located at the circumferential edge of the windshield component 13, and the air inlet channel 130 can be formed only on the lower side of the windshield component 13, or on the lower side and left and right sides of the windshield component 13. In this embodiment, the air inlet channel 130 is arranged in a ring shape around the circumference of the windshield component 13, and has a larger air inlet area.

[0062] The air inlet channel 130 can be evenly distributed or unevenly distributed around the circumference of the wind shield assembly 13. In this embodiment, the air inlet area of ​​the air inlet channel 130 gradually decreases from top to bottom. The air inlet area at the top is large, and the air inlet area at the bottom is small, so that a negative pressure area is formed below the wind shield assembly 13, which improves the smoking efficiency. The smoke enters the first smoke inlet 121 from the bottom of the air inlet channel 130, and part of the smoke enters the first smoke inlet 121 from the top or the left and right sides of the air inlet channel 130. Figure 8 The middle arrow shows the direction of gas flow. In other embodiments, the air inlet area of ​​the air inlet channel 130 gradually increases from top to bottom; or, the air inlet area of ​​the air inlet channel 130 gradually decreases or increases from left to right.

[0063] When the movable smoke collecting hood 12 is opened, a slope gradually tilted backward from top to bottom is formed, covering the upper part of the cooker. The first smoke inlet 121 is opened on the slope, and the wind shielding component 13 shields the first smoke inlet 121 .

[0064] In one embodiment, the wind shield assembly 13 includes a wind shield 131, and an air inlet channel 130 is defined between the circumferential edge of the wind shield 131 and the movable smoke collecting hood 12. The wind shield 131 has a large wind shielding area, and can cool down and block and slow down the oil smoke entering the first smoke inlet 121, and part of the oil smoke can condense on the wind shield 131.

[0065] In this embodiment, the wind shield 131 is located in front of the first smoke inlet 121. When in use, the wind shield 131 is close to the cooker, which can shorten the smoke flow path and improve the condensation effect.

[0066] In this embodiment, the windshield 131 is connected to the movable smoke collecting hood 12. In order to make full use of the space, part of the front surface of the movable smoke collecting hood 12 is recessed inward to form a receiving cavity, the first smoke inlet 121 is provided on the bottom wall of the receiving cavity, and the windshield 131 is arranged in the receiving cavity. The receiving cavity provides space for the windshield 131, so that the windshield 131 does not protrude from the movable smoke collecting hood 12, thereby ensuring the appearance of the integrated structure.

[0067] The windshield 131 is detachably connected to the movable smoke collecting hood 12, which is convenient for installation, removal and replacement. It can be a snap connection, a threaded connection or a magnetic connection. Figures 5 to 7 As shown, one end of the windshield 131 is rotatably connected to the movable smoke collecting hood 12, and the other end of the windshield 131 is snap-fitted with the movable smoke collecting hood 12. Specifically, the lower part of the movable smoke collecting hood 12 is provided with an insertion port 124, one end of the windshield 131 is provided with a protrusion 1311, the protrusion 1311 is inserted into the insertion port 124 and can rotate in the insertion port 124, the upper part of the movable smoke collecting hood 12 is provided with a bayonet 125, and the other end of the windshield 131 is provided with a clamping protrusion 1312, and the clamping protrusion 1312 is snap-fitted with the bayonet 125. During installation, the protrusion 1311 is first inserted into the insertion port 124, and then the clamping protrusion 1312 is snap-fitted with the bayonet 125.

[0068] In other embodiments, the windshield 131 is connected to the movable smoke hood 12 by at least two buckles. Specifically, a slot is provided on the movable smoke hood 12, and a buckle is provided on the windshield 131, and the buckle is connected to the slot. During installation, the windshield 131 is pressed onto the movable smoke hood 12 so that the buckle is connected to the slot.

[0069] In some embodiments, see Figures 17 to 19 The movable smoke collecting hood 12 is provided with a magnetic base 14 , and a magnetic member is provided on the magnetic base 14 , and the top of the wind shield 131 is magnetically connected to the magnetic member. Specifically, the magnetic base 14 is located at the upper part of the first smoke inlet 121 .

[0070] Typically, the shape of the windshield 131 matches the shape of the first smoke inlet 121. In this embodiment, the first smoke inlet 121 is rectangular, and the windshield 131 is a rectangular plate.

[0071] The front surface of the movable smoke collecting hood 12 is provided with at least two first smoke inlets 121, and a set of wind shielding components 13 is provided corresponding to each first smoke inlet 121. In this embodiment, there are two first smoke inlets 121, corresponding to the left and right burners of the stove. A set of wind shielding components 13 is provided corresponding to each first smoke inlet 121.

[0072] In one embodiment, a fence hole is provided on the wind shield 131. The fence hole increases the air intake of the wind shield 131 and improves the smoking effect. The fence hole can be provided at any position of the wind shield 131 as required. For example, the fence hole is provided at the bottom of the wind shield 131 to increase the air intake at the bottom of the wind shield 131. The fence hole can be circular, oval or long.

[0073] In another embodiment, the wind shield assembly 13 includes a wind shield 131 and an oil net, and an air inlet channel 130 is defined between the circumferential edge of the wind shield 131 and the movable smoke collecting hood 12. The oil net is arranged at the rear side of the wind shield 131, and the oil net covers the air inlet channel 130; and / or, the oil net covers the first smoke inlet 121. The oil net can filter the oil smoke. Since the external oil smoke enters the first smoke inlet 121 from the air inlet channel 130, the oil net is arranged to cover the air inlet channel 130 and / or the first smoke inlet 121, so that all the oil smoke entering the first smoke inlet 121 can be filtered.

[0074] When the oil net covers the air inlet channel 130, the oil net may be annular. The wind shield 131 is defined to extend in the first plane, and the oil net may extend parallel to the first plane, or may extend perpendicular to the first plane, or may even be arranged at an acute angle to the first plane. Alternatively, part of the oil net extends parallel to the first plane, and part of the oil net extends perpendicular to the first plane.

[0075] When the oil net covers the first smoke inlet 121, the coverage area of ​​the oil net is larger and it is also easy to install. The oil net can extend parallel to the first plane; or part of the oil net extends parallel to the first plane and part of the oil net extends perpendicular to the first plane.

[0076] When the oil net covers the air inlet channel 130 and the first smoke inlet 121 , part of the oil net may extend parallel to the first plane, and part of the oil net may extend perpendicular to the first plane.

[0077] The oil screen can be provided with one layer, or two layers or more.

[0078] When an oil net is provided, the oil net is connected to the wind shield 131; or, the oil net is connected to the fixed smoke hood 11; or, the oil net is connected to the movable smoke hood 12. When the wind shield 131 is connected to the oil net, the wind shield 131 and the oil net can be fixed as one, and can be snap-connected, threaded, or magnetically connected. When the wind shield 131 is connected to the oil net, the wind shield 131 can be removed separately or as a whole with the oil net. After the wind shield 131 is removed separately, the oil net can filter the oil smoke at the first smoke inlet 121. When the wind shield 131 is connected to the oil net, the oil net and the wind shield 131 can be movably connected, and the distance between the oil net and the wind shield 131 is adjustable.

[0079] When the oil net is connected to the fixed smoke hood 11, the fixed smoke hood 11 and the oil net can be fixedly connected or movably connected. The fixed connection can be a snap connection, a threaded connection or a magnetic connection, and the movably connected can be a sliding connection or a rotating connection. In some embodiments, the fixed smoke hood 11 includes a smoke hood rear plate, and the oil net is connected to the smoke hood rear plate. Specifically, the smoke hood rear plate is the rear plate of the fixed smoke hood 11.

[0080] When the oil net is connected to the movable smoke collecting hood 12, the movable smoke collecting hood 12 and the oil net can be fixedly connected or movably connected. The fixed connection can be a snap connection, a threaded connection or a magnetic connection, and the movable connection can be a sliding connection or a rotating connection.

[0081] In some embodiments, the angle of the windshield assembly 13 is adjustable around the left and right direction of the fixed smoke hood 11; and / or the position of the windshield assembly 13 is adjustable along the front and rear direction of the fixed smoke hood 11. The windshield assembly 13 can be driven to move by an existing cylinder or motor drive transmission mechanism.

[0082] In some embodiments, the position of the wind shield 131 is adjustable along the front-to-back direction of the movable smoke collecting hood 12 to change the air intake area of ​​the air intake channel 130. When the wind shield 131 is connected to the movable smoke collecting hood 12, the adjustment structure for adjusting the position is arranged between the wind shield 131 and the movable smoke collecting hood 12; when the wind shield 131 is connected to the oil net, the adjustment structure for adjusting the position is arranged between the wind shield 131 and the oil net.

[0083] The adjustment structure includes a screw rod, which passes through the wind shield 131 and is connected to the threaded hole on the movable smoke collecting hood 12 or the oil net. By rotating the screw rod, the length of the screw rod outside the threaded hole can be changed, thereby changing the position of the wind shield 131. Generally, the longer the length of the screw rod outside the threaded hole, the farther the wind shield 131 is from the first smoke inlet 121, and the larger the air inlet area of ​​the air inlet channel 130.

[0084] It is understandable that a mounting hole is provided on the windshield 131, and a screw rod is passed through the mounting hole. In order to limit the windshield 131, a limiting sleeve can be sleeved on the screw rod, and the limiting sleeve and the head of the screw rod clamp the windshield 131. The limiting sleeve can be an elastic ring sleeved on the screw rod.

[0085] In order to further adjust the position of the windshield 131, two limiting sleeves can be provided on each screw rod, and the two limiting sleeves are distributed on the front and rear sides of the windshield 131 to clamp the windshield 131. The position of the windshield 131 can be changed not only by rotating the screw rod, but also by sliding the two limiting sleeves on the screw rod, so that the position of the windshield 131 is larger in adjustment range.

[0086] In some embodiments, the angle of the wind shield 131 is adjustable around the left and right directions of the movable smoke collecting hood 12 to change the air intake area of ​​the air intake channel 130. In other words, the wind shield 131 is rotatable, and the rotation axis of the wind shield 131 extends along the left and right directions of the movable smoke collecting hood 12, so that the angle of the wind shield 131 is adjustable, thereby changing the air intake area of ​​the air intake channel 130. The air intake channels 130 can be evenly distributed around the circumference of the wind shield assembly 13, or can be unevenly distributed.

[0087] Specifically, the windshield 131 is rotatably connected to the movable smoke collecting hood 12 or the oil net through a rotating shaft, and the windshield 131 and the movable smoke collecting hood 12 or the oil net can be locked by a locking member. When the angle of the windshield 131 needs to be adjusted, the locking member is loosened, the windshield 131 is rotated to a desired position, and then the locking member is locked.

[0088] The locking member can be a bolt and a nut. A first mounting hole for passing the bolt is provided on the wind shield 131, and a second mounting hole for passing the bolt is provided on the movable smoke collecting hood 12 or the oil net. Both the first mounting hole and the second mounting hole are long holes, which facilitate alignment after adjusting the angle of the wind shield 131. The bolt is locked with the nut after passing through the first mounting hole and the second mounting hole.

[0089] On the premise that the first smoke inlet 121 is provided on the front surface of the movable smoke collecting hood 12, further smoke inlets may be added. Fig. 9 and Fig.10 As shown, the top surface of the movable smoke collecting hood 12 is provided with a second smoke inlet 122 connected to the smoke collecting chamber. When the movable smoke collecting hood 12 is closed, it is located inside the fixed smoke collecting hood 11, and the second smoke inlet 122 is located inside the fixed smoke collecting hood 11, which can protect the first smoke inlet 121 and prevent dust accumulation. When the movable smoke collecting hood 12 is opened, it protrudes from the front side of the fixed smoke collecting hood 11 and the second smoke inlet 122 is located outside the fixed smoke collecting hood 11. Fig.10 The arrows in the middle show the direction of gas flow.

[0090] In this embodiment, the second smoke inlets 122 extend in a long strip shape along the left and right direction of the movable smoke collecting hood 12 to fully utilize the space on the top surface of the movable smoke collecting hood 12 so that the second smoke inlets 122 are evenly distributed and have a larger smoking area.

[0091] In some embodiments, the second smoke inlet 122 is circular, elliptical or polygonal. The second smoke inlet 122 can be a plurality of smoke inlet holes distributed along the left and right directions of the movable smoke collecting hood 12. The shapes of the plurality of smoke inlet holes can be the same or different, and the flow areas of the respective smoke inlet holes can be the same or different.

[0092] In some embodiments, Fig.11 As shown, a third smoke inlet 123 is provided on the left side and / or the right side of the movable smoke collecting hood 12, and the third smoke inlet 123 connects the outside with the smoke collecting chamber. The first smoke inlet 121, the second smoke inlet 122 and the third smoke inlet 123 exist at the same time, forming a uniform negative pressure zone inside the smoke collecting assembly 10 to the maximum extent. At the same time, adding the third smoke inlet 123 on the left side and / or the right side of the movable smoke collecting hood 12 can increase the negative pressure on the left and right sides, thereby improving the smoke leakage on the left and right sides.

[0093] The moving path of the movable smoke hood 12 can be a straight line or a curve; in the present embodiment, the movable smoke hood 12 rotates around a fixed axis, and the movable smoke hood 12 flips forward while approaching the stove below. Specifically, the bottom end of the movable smoke hood 12 is rotatably connected to the fixed smoke hood 11. A pin or a rotating shaft is provided at the rotating connection. In other embodiments, the movable smoke hood 12 can move along a first straight line, and the first straight line extends downwardly from the back to the front, so that the movable smoke hood 12 moves downward while protruding from the front side of the fixed smoke hood 11, approaching the stove below.

[0094] In this embodiment, the cross section of the movable smoke collecting hood 12 along the front-to-back direction is substantially in the shape of an inverted triangle, which facilitates the rotation of the movable smoke collecting hood 12. The front surface of the movable smoke collecting hood 12 gradually tilts backward from top to bottom.

[0095] Normally, the front surface of the fixed smoke hood 11 is an inclined surface. In order to facilitate the complete retraction of the movable smoke hood 12 into the fixed smoke hood 11 in the closed state, the front surface of the movable smoke hood 12 gradually tilts backwards from top to bottom. When the movable smoke hood 12 is retracted into the fixed smoke hood 11, the body of the movable smoke hood 12 is thinner and no longer occupies space in the kitchen. When opened, the movable smoke hood 12 protrudes from the front side of the fixed smoke hood 11, so that the movable smoke hood 12 and the fixed smoke hood 11 form a larger smoke collecting area, and the movable smoke hood 12 is closer to the stove, which can shorten the oil smoke path, smoke out faster, and improve the smoking effect.

[0096] The angle between the front surface of the movable smoke hood 12 and the front surface of the fixed smoke hood 11 is greater than or equal to 0 degrees and less than or equal to 90 degrees. In the closed state, the front surface of the movable smoke hood 12 can be parallel to the front surface of the fixed smoke hood 11. In the open state, the front surface of the movable smoke hood 12 protrudes from the front surface of the fixed smoke hood 11, can be closer to the stove, can shorten the oil smoke path, smoke faster, and thus improve the smoking effect. In this embodiment, the angle between the front surface of the movable smoke hood 12 and the front surface of the fixed smoke hood 11 is greater than or equal to 0 degrees and less than or equal to 20 degrees.

[0097] In the open state, the bottom end of the front surface of the movable smoke collecting hood 12 is located inside the fixed smoke collecting hood 11 and above the oil cup 30 , so that oil and dirt can flow into the oil cup 30 .

[0098] See also Figures 1 to 4 , Figure 8 and Fig.10 The air guide assembly 20 includes an air guide plate 21, which is movably connected to the fixed smoke collecting hood 11. The fixed smoke collecting hood 11 supports the movable smoke collecting hood 12 and the air guide plate 21, and the fixed smoke collecting hood 11 is connected to the housing 100. A fan is provided in the housing 100 to absorb the oil smoke and discharge it through the smoke guide channel in the housing 100.

[0099] In the closed state, the movable smoke hood 12 is located inside the fixed smoke hood 11, and at least part of the air guide plate 21 covers the movable smoke hood 12, with a neat appearance and strong integrity; when switching from the closed state to the open state, the air guide plate 21 flips forward, the movable smoke hood 12 flips forward and protrudes from the front side of the fixed smoke hood 11, and the air guide plate 21, the movable smoke hood 12 and the fixed smoke hood 11 form a smoke collecting cavity. Since the movable smoke hood 12 protrudes from the front side of the fixed smoke hood 11, the movable smoke hood 12 is closer to the stove, improving the smoking effect; there is no need to reduce the distance between the smoke collecting cavity and the stove countertop, and the smoking effect is guaranteed under the premise of avoiding the smoke collecting structure from affecting the user's cooking operation and cooking utensils.

[0100] In this embodiment, one air guide plate 21 is provided. At least part of the air guide plate 21 covers the movable smoke collecting hood 12, and the air guide plate 21 may be completely covered by the movable smoke collecting hood 12, or part of the air guide plate 21 may be covered by the movable smoke collecting hood 12. In other embodiments, two or more air guide plates 21 may be provided. When two or more air guide plates 21 are provided, at least one air guide plate 21 may cover the movable smoke collecting hood 12, and the remaining air guide plates 21 may not cover the movable smoke collecting hood 12.

[0101] The air guide plate 21 covers the movable smoke collecting hood 12 , and may completely cover the movable smoke collecting hood 12 , or may partially cover the movable smoke collecting hood 12 .

[0102] When closed, the air guide plate 21 is retracted and covers the movable smoke hood 12, at least partially covering the fixed smoke hood 11. It can be that the air guide plate 21 covers the left and right edges of the fixed smoke hood 11 in the left and right directions. After the air guide plate 21 is retracted, the front surface of the smoke collecting structure is a plane, that is, the air guide plate 21 is flush with part of the fixed smoke hood 11, so as to ensure a neat appearance and strong integrity.

[0103] When in use, the position of the kitchen appliance is set as needed so that the smoke collecting chamber formed in the open state is just above the stove, so as to form a negative pressure area above the stove, which can effectively absorb the oil smoke into the smoke collecting chamber, thereby improving the smoke extraction effect of the range hood. Usually, the bottom of the smoke collecting chamber is the air inlet, which faces downward to face the stove, and the smoke flows into the smoke collecting chamber from bottom to top.

[0104] The smoke collecting chamber includes a first smoke chamber 201 located at the bottom and a second smoke chamber 202 located at the top. The first smoke chamber 201 and the second smoke chamber 202 are connected through a narrowing opening 203. When the air guide plate 21 is opened, a larger space is formed between the air guide plate 21 and the fixed smoke collecting hood 11. The space covers the top of the cooker. Since the air guide plate 21 is flipped forward, the cross-section of the space is basically fan-shaped along the front and rear directions of the fixed smoke collecting hood 11. Since the movable smoke collecting hood 12 is flipped forward and protrudes from the front side of the fixed smoke collecting hood 11, the movable smoke collecting hood 12 forms a convex structure in the space, which separates the space into the first smoke chamber 201 and the second smoke chamber 202.

[0105] A narrowing 203 is formed between the first smoke chamber 201 and the second smoke chamber 202, so that the smoke chamber is in the shape of a gourd. The volume of the upper second smoke chamber 202 is smaller than the volume of the lower first smoke chamber 201, so the smoke chamber includes two smoke chambers, one smaller on the top and one larger on the bottom, in the shape of a gourd. It can be understood that the gas passes through the narrowing 203 from the first smoke chamber 201 to the second smoke chamber 202, and the narrowing 203 accelerates the gas, so the gas flow rate in the second smoke chamber 202 is greater than the gas flow rate in the first smoke chamber 201. The arrow in the figure shows the direction of gas flow. During the gas flow process, the pressure in the second smoke chamber 202 is less than the pressure in the first smoke chamber 201, so that the smoke flows rapidly to the second smoke chamber 202. Since the pressure in the second smoke chamber 202 is relatively small, the negative pressure in the second smoke chamber 202 acts on the first smoke chamber 201 through the narrowed opening 203, making the negative pressure in the first smoke chamber 201 larger, and the smoke chamber just covers the top of the cooker, thereby improving the smoke extraction effect of the range hood.

[0106] The smoke enters the second smoke chamber 202 through the first smoke chamber 201 and the narrowed opening 203. In order to prevent the second smoke chamber 202 from leaking smoke, the air guide assembly 20 further includes two shielding plates 22, which are located on the inner surface of the air guide plate 21 and are arranged at intervals. The two shielding plates 22 respectively shield the left and right ends of the second smoke chamber 202. As a result, the smoke can only enter the second smoke chamber 202 from the narrowed opening 203, and the second smoke chamber 202 can be formed into a relatively closed space with single-sided air intake, thereby increasing the pressure and wind speed at the second smoke inlet 122, thereby strengthening the negative pressure of the first smoke chamber 201 and improving the smoking effect.

[0107] In this embodiment, the front surface of the movable smoke hood 12 and the air guide plate 21 form a first smoke chamber 201, the top surface of the movable smoke hood 12, the air guide plate 21 and the fixed smoke hood 11 form a second smoke chamber 202, and the junction between the front surface and the top surface of the movable smoke hood 12 and the air guide plate 21 form a narrowed opening 203.

[0108] In some embodiments, the top surface of the movable smoke collecting hood 12 is parallel to the air guide plate 21 and extends toward the stove, so that the second smoke inlet 122 is closer to the stove, improving the smoking effect.

[0109] The air guide plate 21 and the movable smoke collecting hood 12 can both move relative to the fixed smoke collecting hood 11 , and the two can move independently of each other, or share a driving mechanism, or can be linked to each other.

[0110] In some embodiments, the air guide plate 21 and the movable smoke collecting hood 12 move independently of each other, so that the size of the smoke collecting chamber can be adjusted. The air guide plate 21 and the movable smoke collecting hood 12 move independently of each other, and the size of the smoke collecting chamber can be adjusted by the cooperation of the air guide plate 21 and the movable smoke collecting hood 12, so as to adapt to various usage scenarios and ensure the smoking effect under different oil smoke concentrations.

[0111] Specifically, the first driving mechanism drives the air guide plate 21 to move, and the second driving mechanism drives the movable smoke collecting hood 12 to move, and the first driving mechanism and the second driving mechanism are independent of each other. When opening, the first driving mechanism is turned on, and after driving the air guide plate 21 to fully open or after the first driving mechanism is turned on for a set time, the second driving mechanism is turned on, and drives the movable smoke collecting hood 12 to open, so as to prevent the air guide plate 21 from interfering with the movable smoke collecting hood 12.

[0112] The first driving mechanism may adopt a conventional mechanism for driving the air guide plate 21 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 hinged to the fixed smoke hood 11, the other end of the first connecting rod is hinged to the air guide plate 21, the body of the first push rod motor is hinged to the fixed smoke hood 11, and the push rod of the first push rod motor is hinged to the rod body of the first connecting rod. The extension or shortening of the push rod of the first push rod motor can drive the first connecting rod to rotate, thereby driving the air guide plate 21 to flip.

[0113] The movable smoke collecting hood 12 is fixedly connected to the first rotating shaft, and the first rotating shaft is rotatably connected to the fixed smoke collecting hood 11. The second driving mechanism can adopt a mechanism that can drive the first rotating shaft to rotate. In some embodiments, the second driving mechanism includes a motor, a driving gear and a driven gear, the driven gear is arranged on the first rotating shaft, the driving gear is arranged on the motor shaft of the motor, the driving gear is meshed with the driven gear, the motor drives the driving gear to rotate, and then the first rotating shaft can be driven to rotate through the driven gear.

[0114] In some embodiments, the air guide plate 21 and the movable smoke collecting hood 12 share a driving mechanism, and the driving mechanism is configured to drive the air guide plate 21 and the movable smoke collecting hood 12 to open or close synchronously, so that the movements of the two are coordinated with each other, ensuring the stability of the movement and improving the switching efficiency.

[0115] In some embodiments, Figures 12 to 16As shown, the air guide plate 21 is linked with the movable smoke collecting hood 12. When the air guide plate 21 is opened, it flips forward to drive the movable smoke collecting hood 12 to protrude from the front side of the fixed smoke collecting hood 11, and the air guide plate 21, the movable smoke collecting hood 12 and the fixed smoke collecting hood 11 form a smoke collecting cavity; when the air guide plate 21 is closed, it drives the movable smoke collecting hood 12 to be retracted into the fixed smoke collecting hood 11, and the air guide plate 21 covers the movable smoke collecting hood 12.

[0116] The smoke collecting structure includes a pushing mechanism and a linkage mechanism 40. The pushing mechanism is configured to drive the air guide plate 21 to move. The linkage mechanism 40 connects the movable smoke collecting hood 12 and the air guide plate 21. The linkage mechanism 40 can be linked with the air guide plate 21 to drive the movable smoke collecting hood 12 to move. When opening, the pushing mechanism pushes the air guide plate 21 to open, and the air guide plate 21 flips forward to drive the linkage mechanism 40 to move. The linkage mechanism 40 transmits the movement to the movable smoke collecting hood 12, thereby driving the movable smoke collecting hood 12 to protrude from the front side of the fixed smoke collecting hood 11.

[0117] The ejection mechanism may adopt a conventional mechanism for driving the air guide plate 21 to flip. In some embodiments, the ejection mechanism includes a push rod motor and a connecting rod, one end of the connecting rod is hinged to the fixed smoke hood 11, the other end of the connecting rod is hinged to the air guide plate 21, the body of the push rod motor is hinged to the fixed smoke hood 11, and the push rod of the push rod motor is hinged to the rod body of the connecting rod. The extension or shortening of the push rod of the push rod motor can drive the connecting rod to rotate, thereby driving the air guide plate 21 to flip.

[0118] The linkage mechanism 40 includes a linkage member 41, which is disposed between the movable smoke collecting hood 12 and the air guide plate 21. One of the movable smoke collecting hood 12 and the air guide plate 21 is rotatably connected to the linkage member 41, and the other is slidably connected to the linkage member 41. When the air guide plate 21 is opened, the air guide plate 21 flips forward to drive the linkage member 41 to move, so that one end of the linkage member 41 slides along the air guide plate 21 or the movable smoke collecting hood 12, thereby driving the movable smoke collecting hood 12 to protrude from the front side of the fixed smoke collecting hood 11.

[0119] In this embodiment, one end of the linkage member 41 is rotatably connected to the top surface of the movable smoke collecting hood 12, and the other end of the linkage member 41 is slidably connected to the inner surface of the air guide plate 21. When the air guide plate 21 is opened, the air guide plate 21 flips forward to drive the linkage member 41 to move, so that one end of the linkage member 41 slides along the air guide plate 21, thereby driving the movable smoke collecting hood 12 to protrude from the front side of the fixed smoke collecting hood 11. The linkage member 41 and the movable smoke collecting hood 12 can be connected by a hinge.

[0120] The inner surface of the air guide plate 21 is provided with a slideway 23, and the end of the linkage member 41 is provided with a roller 42, which is arranged in the slideway 23. By setting the roller 42 to roll along the slideway 23, the sliding friction is converted into rolling friction, the friction force is reduced, and the sliding is smooth.

[0121] The first smoke chamber 201 is located below the linkage member 41, and the second smoke chamber 202 is located above the linkage member 41. In order not to affect the connection between the first smoke chamber 201 and the second smoke chamber 202, in some embodiments, the linkage member 41 includes two linkage rods arranged at intervals, and the two linkage rods are arranged at intervals along the left and right directions of the movable smoke collecting hood 12, and a slideway 23 is provided for each linkage rod. In some embodiments, the linkage member 41 is a partition, and a connecting hole is provided on the partition, and the first smoke chamber 201 and the second smoke chamber 202 are connected through the connecting hole.
