The invention provides a filter assembly.

In an embodiment of the present invention, referring to fig. 4 and 5 in combination, the filter assembly 10 includes:

a filter element 11, the filter element 11 having a rotation axis, a first filter segment 111 and a second filter segment 112 arranged along the rotation axis, the first filter segment 111 and the second filter segment 112 each having a plurality of filter holes 1121; and the number of the first and second groups,

a plurality of guide vanes 12 connected to the filter member 11 and disposed at the first filter stage 111, the guide vanes 12 extending along the rotation axis, and a plurality of the guide vanes 12 being arranged around the rotation axis.

In the present embodiment, the first filter segment 111 and the second filter segment 112 each extend along the rotation axis in an elongated structure. Specifically, the first filter segment 111 and the second filter segment 112 are both filter cartridges and have a generally circular cylindrical structure. Optionally, the axis of the first filter segment 111 and the axis of the second filter segment 112 are located on the same line. In addition, the first filter segment 111 and the second filter segment 112 may also be square tubular structures; alternatively, the first filter stage 111 and the second filter stage 112 may have a spiral structure.

In one embodiment, the first filter stage 111 and the second filter stage 112 are disposed adjacent to each other and connected to each other. Of course, the first filter segment 111 and the second filter segment 112 may be of unitary construction. In other embodiments, other filter segments may be disposed between the first filter segment 111 and the second filter segment 112.

The guide vanes 12 may be connected to the circumferential wall of the first filter segment 111, or an end cover may be provided on the end surface of the first filter segment 111, and the guide vanes 12 are connected to the end cover. The guide vane 12 has a substantially elongated plate-like structure, and has a small thickness to have a light weight, thereby facilitating rotation. The guide vanes 12 act as a force-bearing member for the air flow, which directly acts on the guide vanes 12, thereby pushing the first filter segment 111 to rotate, and thus rotating the entire filter assembly 10. Optionally, the filter assembly 10 includes at least three guide vanes 12, which effectively ensure the free rotation of the filter assembly 10.

In the invention, the guide vanes 12 provide a stressed surface for the airflow, so that the airflow acts on the guide vanes 12, and after the airflow is blocked by the surface of the guide vanes 12, the airflow pushes the guide vanes 12 to rotate, thereby driving the whole filter assembly 10 to rotate. In the process that the airflow pushes the guide vane 12 to rotate, the airflow passes through the filter holes 1121 on the filter assembly 10, and the filter assembly 10 rotates to continuously collide with the airflow, so that particulate matters in the airflow, such as grease and the like, are intercepted by the filter holes 1121, i.e., the first filter section 111 and the second filter section 112, and the collision process can fully filter the airflow, enhance the filtering effect, and reduce the probability of the fan 30 being polluted by oil smoke.

In addition, grease in the oil smoke is caught on the filter assembly 10, and although the filter assembly 10 can throw out most of the oil by rotating itself, a small amount of the grease remains on the filter assembly 10. The longer the filter assembly 10 is in use, the more grease that accumulates and the greater the weight of the filter assembly 10 itself. When the gear of the lampblack purification device is low and the back pressure of the pipeline is high, the larger the mass of the filter assembly 10 is, the larger the inertia is, and the difficulty in starting the filter assembly 10 is caused, namely the filter assembly 10 is difficult to rotate under the action of the airflow. In view of the above, in the embodiment of the present invention, the guide vanes 12 are only partially disposed on the filtering structure of the filtering assembly 10, that is, the guide vanes 12 are disposed on the first filtering segment 111, and the guide vanes 12 are not disposed on the second filtering segment 112, so that the number of the guide vanes 12 can be reduced, the overall weight of the filtering assembly 10 can be further reduced, the rotational inertia of the filtering assembly 10 can be reduced, and the filtering assembly 10 can be conveniently started.

In one embodiment, the guide vane 12 is located on the outer surface of the first filter segment 111, and a plurality of guide vanes 12 are arranged around the first filter segment 111, such that the axis of the first filter segment 111 coincides with the rotation axis. Specifically, in the embodiment where the first filter segment 111 is a filter cartridge, the guide vanes 12 are disposed on the outer circumferential surface of the first filter segment 111, and the plurality of guide vanes 12 are arranged along the circumferential direction of the first filter segment 111. After the guide vane 12 is disposed on the outer surface of the first filtering section 111, the airflow blows the guide vane 12 first, and then is filtered through the filtering holes 1121, and since the power of the airflow is not lost by the filtering holes 1121 before contacting the guide vane 12, the kinetic energy of the airflow is large when contacting the guide vane 12, so that the rotation speed of the guide vane 12 is faster, which is beneficial to driving the whole filtering assembly 10 to rotate.

In other embodiments, the guide vane 12 may also be disposed inside the first filter segment 111, such that the first filter segment 111 wraps the guide vane 12, that is, when the airflow passes through the first filter segment 111, the airflow first collides with the first filter segment 111 and then contacts the guide vane 12, so that the first filter segment 111 rotates freely. The outermost side of the first filtering section 111 is beneficial to throwing out oil on the first filtering section 111 without being blocked by other parts, and the outermost side of the first filtering section 111 can increase the surface area and increase the collision probability with oil smoke. The whole outer surface of the first filter section 111 is in a cylindrical shape, so that the appearance is more integral, and the user can conveniently unpick and wash the filter.

In one embodiment, the first filter segment 111 and the second filter segment 112 are both filter cartridges, and the diameter D of the first filter segment 111 is smaller than the diameter D of the second filter segment 112. In this embodiment, the diameter d of the first filtering section 111 is smaller, so that the weight of the first filtering section 111 is lighter, and after the first filtering section 111 and the guide vane 12 are combined, the overall weight of the first filtering section 111 and the guide vane is lighter and closer to the second filtering section 112 with a larger diameter, so that the weights of the two ends of the filtering assembly 10 are equivalent, and the filtering assembly 10 can be prevented from shaking due to unbalanced weights of the left end and the right end when rotating.

The guide vane 12 has an outer edge 121 and an inner edge 122 extending in a length direction, the outer edge 121 and the inner edge 122 are disposed opposite to each other, and the inner edge 122 is disposed near an outer circumferential surface of the first filter segment 111, and the outer edge 121 is disposed far from the outer circumferential surface of the first filter segment 111. Optionally, the outer edge 121 is flush with the outer circumferential surface of the second filter segment 112. In this embodiment, the guide vanes 12 are not disposed beyond the outer peripheral surface of the second filtering section 112, which is equivalent to making the rotation radius of the whole filtering assembly 10 the radius of the second filtering section 112, and the rotation radius is smaller, and the overall rotation torque is small, so that the self-rotation of the filtering assembly 10 is facilitated. In addition, it is possible to prevent a user from bending the guide vanes 12 when cleaning or taking the filter assembly 10. In other embodiments, the outer edge 121 of the guide vane 12 may be disposed lower than the outer circumferential surface of the second filter segment 112.

In one embodiment, a plurality of guide vanes 12 are radially distributed on the first filter segment 111, and specifically, the guide vanes 12 have an inner edge 122 and an outer edge 121 distributed along the width direction thereof. This structure can guarantee to arrange more guide vane 12 on first filter stage 111, increases filter area to also make and form the field angle between adjacent guide vane 12 and do benefit to the air current and enter into between two adjacent guide vane 12.

Alternatively, the guide vane 12 is curved in the width direction. The curved guide vanes 12 have a larger frontal area and thus receive a larger thrust than a straight plate. In addition, after the arc design is adopted, the width direction of the guide vane 12 gradually deviates from the radial direction of the first filter section 111, that is, the width direction of the guide vane is more deviated to the circumferential direction of the first filter section 111, so that the air flow pushes the guide vane and moves more smoothly along the plate surface.

In one embodiment, the filter member 11 further includes a first support disc 13 and a second support disc 14, and the guide vanes 12 are respectively disposed on the first support disc 13 and the second support disc 14 at two ends along the length. Thus, both ends of the guide vane 12 are fixed, and the guide vane 12 can be effectively prevented from shaking during rotation. The guide vanes 12 are arranged on the first supporting disk 13 and the second supporting disk 14, when the guide vanes 12 need to be cleaned, the whole first supporting disk 13 and the second supporting disk 14 can be taken out, and the guide vanes 12 do not need to be detached individually for cleaning.

The first support disc 13 and said second support disc 14 are substantially circular discs which facilitate the rotation and are stressed more evenly throughout the rotation. Optionally, the axis of rotation of the filter assembly 10 coincides with the axis of the first support disc 13 and said second support disc 14. And, a plurality of guide vanes 12 on the same first supporting disk 13 are evenly arranged in the supporting disk circumference. The first support disc 13 and the second support disc 14 in the embodiment of the present invention have the same or similar structures, or the first support disc 13 and the second support disc 14 may have different structures.

Referring to fig. 5 to 8 again, in order to facilitate the disassembly and assembly, the guide vane 12 in the embodiment of the present invention is detachably connected to the first supporting plate 13 and the second supporting plate 14. In one embodiment, the first supporting plate 13 and the second supporting plate 14 are provided with insertion holes 131, and the guide vanes 12 are inserted and matched with the insertion holes 131. In other embodiments, the guide vane 12 may also be connected to the first support disk 13 and the second support disk 14 by a screw, or the guide vane 12 may also be clamped to the first support disk 13 and the second support disk 14 by a snap structure, etc.

Specifically, the circumferential surfaces of the first supporting disk 13 and the second supporting disk 14 are both provided with mounting notches 132 communicating with the insertion holes 131; the guide vane 12 is inserted into the insertion hole 131 from the installation notch 132, and the end of the guide vane 12 is provided with a limit flange 123, and the limit flange 123 is connected with the corresponding first support disc 13 or second support disc 14, so as to limit the guide vane 12 from moving along the rotation axis.

In one embodiment, the first support disc 13 and the second support disc 14 are removably connected to the filter element 11, respectively. The first supporting disk 13 is close to the second filter segment 112 and is arranged around the first filter segment 111, and the inner diameter of the first supporting disk 13 is larger than the outer diameter of the first filter segment 111; and/or the presence of a gas in the gas,

the second support disc 14 is located at the end face of the first filter segment 111 facing away from the second filter segment 112.

In this embodiment, since the inner diameter of the first supporting disk 13 is larger than the outer diameter of the first filter segment 111, when the first supporting disk 13 is separated from other components on the filter assembly 10, the first supporting disk 13 can slide on the outer circumferential surface of the first filter segment 111 and be separated from the first filter segment 111 in a direction away from the second filter segment 112. Since the second support plate 14 is located at the end surface of the first filter segment 111, when the second support plate 14 is separated from other components on the filter assembly 10, when the second support plate 14 is moved along the rotation axis in a direction away from the first filter segment 111, the guide vanes 12 connected to the second support plate 14 can be moved together with the first support plate 13, so that all the guide vanes 12 are taken out, and the first filter segment 111 and the guide vanes 12 can be cleaned conveniently.

In one embodiment, the second support plate 14 is circular plate-shaped and abuts against the end face of the first filter segment 111. Of course, in other embodiments, the second supporting disk 14 may also be circular and may be sleeved on the first filtering section 111.

Referring to fig. 5, 9 and 10, in an embodiment, two ends of the first filter segment 111 and two ends of the second filter segment 112 are respectively provided with a connecting disc 15, adjacent ends of the first filter segment 111 and the second filter segment 112 are connected to the same connecting disc 15, and the connecting disc 15 covers an end of the corresponding first filter segment 111 or the second filter segment 112. Specifically, the connecting disc 15 has a mounting disc surface 151, a connecting ring rib 152 is arranged on the mounting disc surface 151, end surfaces of the first filtering section 111 and the second filtering section 112 respectively abut against the corresponding mounting disc surface 151 of the connecting disc 15, and the first filtering section 111 and the second filtering section 112 are sleeved on an outer peripheral surface of the connecting ring rib 152, so that the first filtering section 111 and the second filtering section 112 are limited to move along the radial direction and the circumferential direction. And the first filter segment 111 and the second filter segment 112 can be restricted from moving axially by providing two connection discs 15 at both ends of the first filter segment 111 and the second filter segment 112, respectively. In addition, the connecting ring rib 152 may not be provided on the mounting plate surface 151, and the first filter segment 111 and the second filter segment 112 are directly sleeved on the outer peripheral surface of the connecting plate 15. For example, the connecting ring rib 152 is arranged on the connecting disc 15 (shown in fig. 9) of the first filter segment 111, the connecting ring rib 152 is not arranged on the connecting disc 15 (shown in fig. 10) of the second filter segment 111, and the connecting disc 15 covers the end parts of the first filter segment 111 and the second filter segment 112 to prevent the air flow from entering from the end parts. The sharing of the one connecting disc 15 by the adjacent ends of the first filter segment 111 and the second filter segment 112 is advantageous in simplification of structure and can reduce weight. The diameter of the common connecting plate 15 is large so that the end face of the second filter stage 112 can be covered. And the other connecting disc 15 on the first filter segment 111 has a smaller diameter and is similar to the diameter of the first filter segment 111.

In this embodiment, the first support disc 13 and the second support disc 14 are connected to the adjacent connection disc 15, respectively. Namely, the first support disc 13 and the second support disc 14 are also arranged near the end of the first filter segment 111, and the first support disc 13 and the second support disc 14 are limited by the connecting disc 15. The first support disc 13 and the second support disc 14 are respectively clamped, screwed or plugged with the corresponding connection disc 15, and the like. Of course, the first support disc 13 and the second support disc 14 may also be connected to the first filter segment 111 by themselves, for example, using an interference fit or the like. First supporting disk 13 with second supporting disk 14 is connected the back with adjacent connection pad 15, can prevent first supporting disk 13 with second supporting disk 14 rocks on first filter segment 111, so first supporting disk 13 with guide vane 12 on the second supporting disk 14 and first filter segment 111 are relative static to it can drive first filter segment 111 synchronous rotation to have guaranteed guide vane 12.

Referring to fig. 11, in an embodiment, the filter assembly 10 further includes a support rod 16 extending along an axial direction of the filter segment, the support rod 16 penetrates the filter element 11, and a rotation shaft 17 is disposed at an end of the support rod 16. By providing the support rod 16 to connect the rotation shafts 17, the coaxiality of the rotation shafts 17 at both ends of the filter assembly 10 can be ensured.

Optionally, the support bar 16 comprises two support bars 161, the support bars 161 extend along the axial direction of the filter segment, and the long sides of the two support bars 161 are connected with each other. In one embodiment, the support bars 161 have an L-shaped cross section, and the two support bars 161 form a cross-shaped cross section structure. Of course, the cross section of the support bars 161 may be in a straight shape, and the two support bars 161 may be connected to form a cross shape or an L shape.

Referring to fig. 9 and 10 again, the connecting disc 15 is provided with a yielding hole 153, the yielding hole 153 has two connecting sections, and the two support bars 161 are correspondingly inserted into the two connecting sections. For example, in the structure in which the cross-section of the support bar 16 is cross-shaped, the two connection sections of the receding hole 153 are also cross-shaped. With this structure, the support lever 16 and the connection plate 15 can be restricted from rotating relative to each other. In other embodiments, the cross-section of the support rod 16 may also be oval or triangular, etc. And a cross-shaped or L-shaped structure is adopted, so that the supporting rod 16 is lighter in weight and convenient to rotate. In addition, the two ends of the support rod 16 are respectively provided with a mounting flange 162, and the mounting flanges 162 and the connecting plate 15 are fixed through screws.

Optionally, a limiting groove is formed in the rotating shaft 17, the limiting groove is provided with two limiting sections which are arranged in a crossed mode, and the two connecting sections of the supporting rod 16 are correspondingly inserted into the two limiting sections, so that the rotating shaft 17 is prevented from rotating relative to the supporting rod 16.

The invention also provides an oil fume purification device which is a range hood or an integrated stove, and for the dust collection stove, the dust collection stove comprises the range hood and a stove body, wherein the range hood is arranged on the stove body, and the range hood and the stove body are combined to form an integrated dust collection stove.

This fan 30 is centrifugal fan 30 for the wind pressure is bigger, and the oil absorption cigarette effect is better. The dotted lines in fig. 2 are only used to illustrate the division between the air inlet 231 and the air outlet 232, but in other embodiments, the air inlet 231 and the air outlet 232 may be divided from other positions.

Specifically, for the range hood, the housing 20 includes a decorative cover and a smoke collecting cover, the decorative cover is hollow, optionally, the decorative cover is substantially square, a smoke outlet 22 is further provided at the top of the decorative cover, and a check valve is provided at the smoke outlet 22. Of course, the trim cover may also be cylindrical or irregularly shaped, etc. The smoke collecting cover is arranged below the decorative cover and is provided with a smoke suction port 21, and the cooking smoke is sucked into the air duct 23 from the smoke suction port 21 and is discharged from the smoke discharge port 22 under the action of the centrifugal fan 30. Specifically, the housing 20 further includes a front panel 24, the front panel 24 forming a part of the smoke collecting hood, and the smoke suction port 21 is provided on the front panel 24. The range hood and the dust collection range each have a front panel 24 and a back panel 25, the front panel 24 being a panel body facing a user, and the back panel 25 being a panel body disposed against a wall.

In the embodiment of the present invention, the lampblack purification device further includes a filter assembly 10, the filter assembly 10 is rotatably disposed in the air duct 23, and the filter assembly 10 is the filter assembly 10 as described above. Optionally, the filter assembly 10 is disposed at the intake section 231. Referring to fig. 12, in an embodiment, a supporting seat 26 is disposed on the housing 20, a supporting groove is formed on the supporting seat 26, and the rotating shaft 17 of the filtering assembly 10 is rotatably engaged with the supporting groove. In order to facilitate the rotation of the filter assembly 10 and reduce the resistance, a bearing 27 is installed on the support base 26, and the rotation shaft 17 of the filter assembly 10 is connected to the bearing 27.

In one embodiment, the filter assembly 10 can be driven by a fan 30 to rotate, the fan 30 drives the flue gas to move in the air duct 23, and the flue gas pushes the filter assembly 10 to rotate integrally. The filtering component 10 can realize self-rotation only by being pushed by smoke without being driven by a motor, and is beneficial to the simplification of the structure and the reduction of the cost. In one embodiment, a power source may be separately provided to drive the filter assembly 10 to rotate, for example, a motor may be additionally provided to drive the filter assembly 10 to rotate, so as to ensure the smoothness of rotation.

In the invention, the filtering component 10 is arranged in the oil fume purification device, and the filtering component 10 can rotate, so when the smoke flows through the filtering component 10 from the filtering holes 1121, the filtering component 10 rotates to continuously collide the smoke, particulate matters such as grease and the like in the smoke are intercepted by the filtering component 10, and the collision process can fully filter the smoke and enhance the filtering effect. Since the filter assembly 10 is disposed at the air inlet section 231, the smoke can be filtered before entering the fan 30, and therefore, the probability of the fan 30 being polluted by oil smoke can be reduced.

In one embodiment, the filter assembly 10 extends along the length of the oil suction opening, and the rotation axis of the filter assembly 10 is along the length thereof, i.e., the rotation axis of the filter assembly 10 is along the left-right direction. Specifically, the housing 20 includes a front panel 24 and a back panel 25 disposed opposite to the front panel 24, the front panel 24 is provided with the smoke suction port 21, and the smoke suction port 21 refers to a lower smoke suction port 21 for a side-suction and top-suction range hood. The filter assembly 10 is disposed between the front panel 24 and the back panel 25, so as to ensure that the smoke is filtered by the filter assembly 10 and then flows into the fan 30. In addition, filter element 10 sets up between front panel 24 and backplate 25, and the cavity that extends along left and right direction that forms here does benefit to filter element 10 and extends from side to side, and both are more matcing in the shape, consequently can better adapt to filter element 10's setting to guarantee filter element 10 as far as possible and separate wind channel 23 for upper and lower two parts, the gaseous air of significantly reducing is not filtered through filter element 10 and is gone towards fan 30 promptly. In addition, a plurality of filter assemblies 10 may be disposed in the housing 20, and the plurality of filter assemblies 10 may be arranged along the length direction of the smoking opening 21.

In this embodiment, the filter assembly 10 is located downstream of the smoke flow of the smoke port 21. For the range hood, the filter assembly 10 is located above the smoke suction port 21. In the case of the dust collection range, the filter assembly 10 is located below the smoking opening 21. A freely rotatable filter assembly 10 is provided between the fan 30 and the mouthpiece 21. After the cigarette machine is started, airflow flowing through the smoke suction port 21 basically contacts the filtering component 10 to push the filtering component 10 to rotate, the filtering component 10 rotates to continuously collide with oil smoke, grease in the oil smoke is intercepted by the filter screen, and the probability that the fan 30 is polluted by the oil smoke is reduced.

Alternatively, the axis of the fan 30 is in the front-rear direction, and the rear end of the fan 30 is a main air inlet, and the air flow flows into the centrifugal volute from the rear end of the fan 30. In the range hood, the effect of direct suction and direct discharge is achieved by utilizing the matching of the smoke suction port 21 at the lower side and the rear main air inlet of the fan 30, and the resistance of the forward airflow of the fan 30 is reduced. In the integrated stove, the effect of direct suction and direct discharge is achieved by matching the smoke suction port 21 at the upper side with the front main air inlet of the fan 30. Because the main air inlet of the fan 30 is arranged backwards in the scheme, most of the air flow rises along the plane of the back plate 25 after entering the smoking port 21. When the air current flows through the filter assembly 10, the air current passes through the filter holes 1121 to push the wind blocking plate to rotate the filter assembly 10, and the filter assembly 10 filters the soot through the filter holes 1121 whose surface is continuously rotated. Optionally, the distance between the filter assembly 10 and the front panel 24 is smaller than the distance between the filter assembly 10 and the back panel 25. Therefore, most of the smoke runs to the rear side, and flows upwards from the rear side to the main air inlet of the fan 30, so that the direct-suction and direct-discharge effect is achieved.

For the conventional oil smoke purifying device, since the filter screen is fixed at the position of the smoke suction port 21, the oil smoke pollution probability is high, and in order to avoid the condensed grease from blocking the filter holes 1121, the size of the filter screen grating or the through holes is generally large. The through hole rate of the filter screen is increased, the surface area is reduced, the area for the filter screen to collide with and intercept oil smoke is also reduced, and the oil-fat separation degree is reduced relatively. In addition, for the design of the filter screen, the surface of the filter screen is uneven after the filter screen is pressed into a certain shape in general.

In view of the above problems, in the embodiment of the present invention, the filter screen is disposed at the smoke suction port 21, the filter assembly 10 is disposed in the air duct 23, and the aperture of the filter hole 1121 of the filter screen is larger than the aperture of the filter hole 1121 of the filter assembly 10, so that the filter screen primarily filters the oil smoke to filter large particles, the aperture of the filter assembly 10 is smaller, and the filter assembly 10 can freely rotate, thereby further filtering small particles and further increasing the oil smoke filtering efficiency. Because of adopting the form of double filtration, the filtration hole 1121 of the filtration net at the smoking port 21 can be larger, which ensures the smooth flow of the air current, and meanwhile, the filtration area is not required to be increased by compression; the internal filtering component 10 can ensure high oil separation degree, thereby achieving double filtering effect.

Referring to fig. 3, in an embodiment, the first filtering section 111 of the filtering assembly 10 is disposed corresponding to the fan 30. Optionally, two filter assemblies 10 are disposed in the air intake section 231, the two filter assemblies 10 are arranged along the length direction of the smoke suction port 21, the first filter sections 111 of the two filter assemblies 10 are adjacently disposed, and the fan 30 is disposed corresponding to the adjacent ends of the two first filter sections 111. In this embodiment, the first filtering section 111 corresponds to the fan 30, which means that in the range hood, the smoke suction port 21 is located below the fan 30, the first filtering section 111 corresponds to the bottom of the fan 30, at least, the first filtering section 111 and the fan 30 are distributed along the vertical direction, and the second filtering section 112 deviates from the fan 30 along the horizontal direction. In addition, when two filter assemblies 10 are employed, the fan 30 is disposed between the two first filter stages 111. In addition, in the integrated oven, the smoke suction port 21 is located above the fan 30, the first filter segment 111 is disposed corresponding to the top of the fan 30, at least, the first filter segment 111 and the fan 30 are distributed along the up-down direction, and the second filter segment 112 is deviated from the fan 30 along the left-right direction. In other embodiments, one filter assembly 10 may be disposed in the air intake section 231, and a single filter assembly 10 may include two or more first filter sections 111 distributed along the rotation axis, with a plurality of first filter sections 111 disposed adjacent to each other. Alternatively, a plurality of filter assemblies 10 may be further disposed at the air intake section 231, the plurality of filter assemblies 10 are radially arranged, and the plurality of first filter sections 111 are disposed near the central radiation point.

The filter assembly 10 is arranged above the smoke suction port 21 (which refers to a range hood, for a dust collection stove, the filter assembly 10 is arranged below the smoke suction port 21) in two sections, and the fan 30 is positioned in the middle of the whole machine in the left-right direction. As can be seen from fig. 3, although the filter assembly 10 can cover the left and right ends of the smoke port 21, most of the air flow passes through the space below the fan 30 after the fan 30 is started, and the air flow is relatively small at the left and right sides, i.e. the air speed is larger in the middle area of the smoke port 21 than at the two sides. In the embodiment of the present invention, by adjusting the position of the guide vane 12 on the filter assembly 10, that is, the guide vane 12 is disposed in the region of the filter assembly 10 facing the fan 30 in the vertical direction, the guide vane 12 is only disposed on one side with a high wind speed, and the second filter segment 112 is disposed at other positions without the guide vane 12, so that the filter assembly 10 matches the air intake mode of the fan 30 of the whole machine, the number of the guide vanes 12 and the overall weight of the filter assembly 10 can be reduced, the rotational inertia of the filter assembly 10 is reduced, and the filter assembly 10 is convenient to start.

In the embodiment of the invention, after the fan 30 of the range hood or the integrated cooker is started, the filtering component 10 is driven to rotate automatically, so that the oil smoke filtering efficiency is increased. In addition, the filter assembly 10 is lightened by optimizing the position of the guide vane 12, so that the rotational inertia of the filter assembly 10 is reduced, and the filter assembly 10 can normally work under smaller pipeline back pressure with larger gears.

Referring to fig. 2 and 12 again, in order to facilitate the removal of the filter assembly 10, in an embodiment, the housing 20 is provided with a mounting opening 28 communicating with the air duct 23, the housing 20 further includes an opening and closing panel 29 for opening and closing the mounting opening 28, the filter assembly 10 is disposed on the opening and closing panel 29, and the filter assembly 10 is rotatably connected to the opening and closing panel 29. When the opening and closing panel 29 is opened, the filter assembly 10 is opened and exposed together following the movement of the opening and closing panel 29, thereby facilitating the user to wash and disassemble the filter assembly 10. Optionally, the opening and closing panel 29 is rotatably connected, clamped or slidably connected with the front panel 24.

Referring again to fig. 12, in an embodiment, the opening and closing panel 29 includes a panel frame 291 and a panel body 292, the panel frame 291 is disposed on a surface of the panel body 292 facing the air duct 23, and the filter assembly 10 is disposed on the panel frame 291. By splitting the opening and closing panel 29 into the panel frame 291 and the panel body 292, the panel frame 291 can be used as a structural member and made of a material with high strength, thereby enhancing the overall strength of the opening and closing panel 29.

In order to open and close the opening and closing panel 29 in this embodiment, the panel frame 291 has fixing lugs 2911 on the left and right sides, and the fixing lugs 2911 have circular holes for mating connection with through holes in the middle of the rotating bases fixed on the left and right side plates, that is, the opening and closing panel 29 can rotate around the axis of the through holes to open and close.
