Referring to fig. 1 to 3, a smoke exhausting structure 100 according to an embodiment of the application includes a housing 10, an opening and closing panel 20, and a driving mechanism 30.

The smoke evacuation structure 100 may be applied to one of an air conditioning extractor 200, an extractor and an integrated oven, and may be applied to other devices using the smoke evacuation structure 100.

The shell 10 is provided with an air inlet 11 and an air inlet cavity 12 communicated with the air inlet 11.

It should be noted that the smoke exhaust structure 100 generally has a fan, which can provide a suction force for the air intake chamber 12, so that the smoke in the kitchen is sucked into the air intake chamber 12 through the air intake 11 and discharged to the outside.

The opening and closing panel 20 is disposed in the housing 10, and the driving mechanism 30 is disposed in the housing 10 and connected to the opening and closing panel 20 for driving the opening and closing panel 20 to open or shield the air inlet 11.

The opening and closing panel 20 is generally provided outside the housing 10. When the smoke exhaust structure 100 works, the opening and closing panel 20 can open the air inlet 11, and then form a smoke inlet area with the side of the shell 10 where the air inlet 11 is positioned, so that the smoke cage effect is better, the escape of smoke can be prevented, and the smoke exhaust effect of the smoke exhaust structure 100 is improved; when the smoke discharging structure 100 does not work, the opening and closing panel 20 can close the air inlet 11, so that the smoke discharging structure 100 is neat and attractive in appearance, and the smoke of the public flue can be prevented from flowing backwards.

The opening and closing panel 20 can rotate relative to the housing 10 to rotate to a position for opening the air inlet 11 or a position for shielding the air inlet 11 under the driving action of the driving mechanism 30. In other embodiments, the opening and closing panel 20 may perform translational movement, rotational movement, or a combination of translational movements with respect to the housing 10, which is not particularly limited.

Wherein, the housing 10 is also formed with a receiving chamber 13 separated from the air inlet chamber 12, and the driving mechanism 30 is disposed in the receiving chamber 13.

The accommodating cavity 13 separated from the air inlet cavity 12 refers to that the air inlet cavity 12 and the accommodating cavity 13 are separated by a certain blocking structure, and the two cavities are not communicated basically, but a small gap can be allowed for the two cavities to communicate, such as a fit gap and the like. In other ways, the air inlet cavity 12 and the accommodating cavity 13 are not communicated with each other.

Therefore, in the smoke exhaust structure 100 of the embodiment of the application, the accommodating cavity 13 separated from the air inlet cavity 12 is formed in the casing 10, and the driving mechanism 30 is arranged in the accommodating cavity 13, so that the smoke can be concentrated in the air inlet cavity 12 for circulation, and the accumulation of the smoke on the driving mechanism 30 is reduced, thereby enabling the driving mechanism 30 to be normally used for a long time, and prolonging the service life of the driving mechanism 30.

In particular, in the embodiment of the present application, the smoke exhaust structure 100 further includes an oil baffle 40, where the oil baffle 40 is disposed on one side of the air inlet 11 along a direction intersecting the flow direction of the smoke and is disposed inside the housing 10, so as to define a receiving cavity 13 between the side facing away from the air inlet 11 and the housing 10.

The oil baffle 40 is a plate body structure that functions as an oil baffle. The oil baffle 40 may be an integrally formed plate body, or may be assembled by a plurality of plate body structures. The oil baffle 40 may serve as a barrier separating the air intake chamber 12 from the receiving chamber 13.

The flow direction of the flue gas refers to the flow direction of the flue gas in the air inlet cavity 12 after the flue gas enters from the air inlet 11, specifically, the flow direction of the flue gas is a vertical upward direction shown in fig. 3, and the direction intersecting with the flow direction of the flue gas may be a horizontal direction shown in fig. 3 or other directions. In the embodiment of the present application, the air inlet 11 is provided in front of the housing 10, and one side of the air inlet 11 refers to the left side or the right side of the air inlet 11, specifically, the left side and the right side as shown in fig. 3.

The fact that the oil baffle 40 delimits the receiving space 13 between the side facing away from the air inlet 11 and the housing 10 means that the oil baffle 40 can form a space wall of the receiving space 13 between the side facing away from the air inlet 11 and the inner wall of the housing 10.

The mode of defining the accommodating cavity 13 for accommodating the driving mechanism 30 between one side deviating from the air inlet 11 and the shell 10 by arranging the oil baffle 40 is simple, and the oil baffle 40 is simple in structure, does not occupy the space inside the excessive shell 10, and is effective in blocking oil smoke due to blocking on one side of the air inlet 11.

Further, the driving mechanisms 30 include two opposite driving mechanisms, each driving mechanism 30 is connected to the opening and closing panel 20, the oil baffle 40 includes two opposite driving mechanisms, the two oil baffles 40 are respectively located at two opposite sides of the air inlet 11 along the direction intersecting the flow direction of the flue gas, one side of each oil baffle 40 facing away from the air inlet 11 is located between the casing 10 to define a containing cavity 13, and an air inlet cavity 12 is defined between the two oil baffles 40 and the casing 10.

Specifically, the two oil baffles 40 are located on opposite sides of the air inlet 11, respectively, which means the left and right sides of the air inlet 11 as shown in fig. 3.

By arranging two driving mechanisms 30 to drive the opening and closing panel 20 simultaneously, the stability of the opening and closing panel 20 relative to the shell 10 can be improved, and by arranging two corresponding oil baffles 40, two accommodating cavities 13 separated from the air inlet cavity 12 can be formed, and then two driving mechanisms 30 are correspondingly accommodated, so that the two driving mechanisms 30 can reduce oil smoke accumulation.

In some embodiments, the oil baffle 40 and the housing 10 further define an air inlet chamber 12 therebetween, and the air inlet chamber 12 and the accommodating chamber 13 are respectively located on opposite sides of the oil baffle 40.

That is, the side of the oil baffle 40 facing the air inlet 11 is the air inlet chamber 12.

So, through oil baffle 40, can separate between air inlet chamber 12 and hold chamber 13, simplified the setting of separation structure to oil baffle 40 has also been acted as the chamber wall in air inlet chamber 12, when can guide the oil smoke smooth and easy flow, also makes casing 10 inner structure set up compacter.

When the oil baffle 40 includes two opposite oil baffles 40, the air inlet cavity 12 may be formed between the two opposite oil baffles 40, so that the two oil baffles 40 serve as the cavity walls of the air inlet cavity 12 at the same time, so that the oil smoke flows smoothly, and the internal structure of the housing 10 is more compact.

Optionally, two oil baffles 40 are symmetrically disposed inside the housing 10.

Through setting up the symmetry setting of two oil baffles 40 for the oil smoke that gets into from air intake 11 can receive the simultaneous guide of two oil baffles 40, and the oil smoke can flow in air inlet chamber 12 more smoothly fast.

Specifically, the two oil baffles 40 are symmetrically disposed inside the housing 10, and the center of symmetry coincides with the center of the air intake 11.

In this way, the two oil baffles 40 can guide the oil smoke more uniformly, and further the oil smoke can flow in the air inlet chamber 12 more smoothly.

In some embodiments, the oil baffle 40 is circumferentially connected to the inner wall of the housing 10.

It should be noted that the connection referred to herein may be understood as an abutting connection, a fixed connection, for example, a fastening connection by a fixing member such as a bolt, or a connection in which the oil deflector 40 is attached to the inner wall of the housing 10.

Specifically, the oil baffle 40 may be continuously connected to the inner wall of the housing 10 in the circumferential direction thereof, and there may be a certain gap between the oil baffle 40 and the inner wall of the housing 10, so that the oil baffle 40 is not continuously connected to the inner wall of the housing 10. It should be noted that, in order to reduce the oil smoke from the gap between the oil baffle 40 and the inner wall of the housing 10 into the accommodating chamber 13, it is preferable that the oil baffle 40 is continuously connected to the inner wall of the housing 10 along the circumferential direction thereof, but in some cases, for example, when the connection between the bottom of the oil baffle 40 and the inner wall of the housing 10 is lower than the position of the air inlet 11, a proper gap may be left, and this part of the gap does not affect the blocking of the oil smoke by the oil baffle 40, because the oil smoke flows into the air inlet chamber 12 above after entering the air inlet 11, but does not flow through the space below the air inlet 11, usually under the suction effect of the fan.

In some embodiments, the inner wall of the housing 10 has a locating groove, and at least a portion of the edge of the oil baffle 40 has a locating rib protruding into the locating groove.

Through when oil baffle 40 locates in casing 10, make the location bead at the edge of oil baffle 40 stretch into in the constant head tank of casing 10 inner wall, on the one hand can not only fix a position the position of oil baffle 40 relative casing 10, on the other hand also can be that the connection is inseparabler between oil baffle 40 and the inner wall of casing 10, reduces the oil smoke and gets into and hold chamber 13.

In other embodiments, the inner wall of the housing 10 may also have a positioning rib, at least part of the edge of the oil baffle 40 has a positioning groove, and the positioning rib protrudes into the positioning groove. In this way, the same technical effects as described above can be achieved, and the description thereof will be omitted.

In other embodiments, it is also possible to provide the inner wall of the housing 10 with both a positioning groove and a positioning rib, and likewise, at least part of the edge of the oil baffle 40 with both a positioning rib and a positioning groove, which are mutually matched.

Further, a sealing element is arranged between the positioning convex rib and the positioning groove. The seal may be an elastic seal, in particular an elastic sealing strip, such as a silicone sealing strip, a rubber sealing strip or the like.

Referring to fig. 4, in an embodiment of the present application, the housing 10 includes a front plate 14, a rear plate 15, a top plate 16, a bottom plate 17, and side plates 18. The front plate 14 has an air inlet 11, the front plate 14 is opposite to the rear plate 15, the top plate 16 is opposite to the bottom plate 17, the oil baffle 40 is opposite to the side plate 18 and is arranged at intervals, the oil baffle 40 is connected between the front plate 14 and the rear plate 15 and between the top plate 16 and the bottom plate 17, and the accommodating cavity 13 is formed by enclosing the front plate 14, the rear plate 15, the top plate 16, the bottom plate 17, the side plate 18 and the oil baffle 40 together.

Since the air inlet 11 has a relatively large area, and the internal support structure is relatively small and is easily deformed by impact, the oil baffle 40 is connected between the front plate 14 and the rear plate 15 and between the top plate 16 and the bottom plate 17, so that the oil baffle can be supported inside the housing 10, the structural strength of the housing 10 is enhanced, and the deformation caused by impact of the housing 10 during packaging and transportation is reduced.

When the smoke exhaust structure 100 includes two oil baffle plates 40 disposed opposite to each other, the two oil baffle plates 40 can be connected between the front plate 14 and the rear plate 15, and between the top plate 16 and the bottom plate 17, and the two oil baffle plates 40 uniformly support two sides of the air inlet 11 of the housing 10, so that the structural strength of the housing 10 is further enhanced, and the deformation caused by impact of the housing 10 during packaging and transportation is reduced.

In some embodiments, the oil baffle 40 is perpendicular to the front and rear plates 14, 15. The front plate 14 and the rear plate 15 are two plate structures with large areas, and are therefore susceptible to deformation due to impact, and the oil baffle 40 is arranged perpendicular to the front plate 14 and the rear plate 15, so that the oil baffle 40 can be strongly supported between the front plate 14 and the rear plate 15 to effectively resist the deformation of the front plate 14 and the rear plate 15 due to impact.

In the embodiment of the present application, two oil baffle plates 40 are disposed opposite to each other so as to be perpendicular to the front plate 14 and the rear plate 15.

The flange 42 is an edge structure that is folded with respect to the oil deflector main body 41. The flange 42 is typically integrally formed with the oil deflector body 41, such as by stamping.

By providing the flange 42, not only the area of adhesion between the oil baffle 40 and the inner wall of the housing 10 can be increased, but also the structural strength of the housing 10 can be enhanced, and on the other hand, a connection position can be provided for connection between the oil baffle 40 and the inner wall of the housing 10.

Specifically, the flange 42 is provided with a connection hole, and the connection hole can penetrate through the connection piece to be connected with the inner wall of the housing 10. The connection may be a bolt, rivet, or the like. In other embodiments, the oil baffle 40 may be welded or bonded to the inner wall of the housing 10 by the flange 42, which is not particularly limited.

In the embodiment of the application, the burring 42 is provided in pairs on the oil deflector main body 41, for example, two burring 42 are provided opposite to each other in the width direction of the oil deflector main body 41. In this way, the two sides of the oil baffle main body 41 are uniformly stressed, and the connection with the inner wall of the shell 10 is more reliable.

Further, the paired burring 42 may include a plurality of pairs, the plurality of pairs of burring 42 being disposed apart from each other in the length direction of the oil deflector body 41. In this way, the connection between the oil baffle 40 and the inner wall of the housing 10 can be made tighter, and the structural strength of the housing 10 can be further enhanced.

In some embodiments, the driving mechanism 30 includes a push rod motor 31 and a push rod 32, the push rod motor 31 is connected to the push rod 32, and the push rod 32 is connected to the opening and closing panel 20.

Further, the driving mechanism 30 further includes a push rod motor bracket 33, the push rod motor bracket 33 is fixed on the inner wall of the housing 10, and the push rod motor 31 is mounted on the push rod motor bracket 33.

Through setting up push rod motor support 33, can support push rod motor 31 better, strengthen the intensity of casing 10, and avoid casing 10 atress deformation and lead to push rod motor 31 position offset, and then influence the accurate opening and shutting of panel 20.

Further, the smoke exhaust structure 100 further includes a rotating bracket 50, the rotating bracket 50 is rotatably disposed on the housing 10, and the push rod 32 is connected to the rotating bracket 50. Thus, under the action of the push rod motor 31 and the push rod 32, the opening and closing panel 20 can rotate to open or shield the air inlet 11.

Specifically, the rotating bracket 50 is disposed on the inner wall of the housing 10, one end of the rotating bracket 50 is connected to the push rod 32, and the other end is connected to the opening/closing panel 20.

It should be noted that, since the push rod 32 is disposed in the accommodating cavity 13 of the housing 10 and the opening and closing panel 20 is disposed at the outer side of the housing 10, in order to avoid the interference of the rotating bracket 50 with the housing 10 during the rotating motion, in the embodiment of the present application, the housing 10 is provided with a communication hole 19 for communicating the accommodating cavity 13 with the outside, and the rotating bracket 50 is disposed through the communication hole 19.

Further, in order to prevent the oil smoke from entering the accommodating chamber 13 from the communication hole 19, some sealing structure may be added thereto to block the gap between the inner wall of the communication hole 19 and the rotating bracket 50.

In some embodiments, the oil baffle 40 includes at least a first baffle 43, a second baffle 44 and a third baffle 45 sequentially connected along a direction away from the air inlet 11, the second baffle 44 is connected between the first baffle 43 and the third baffle 45, a first bending portion is formed between the second baffle 44 and the first baffle 43, a second bending portion is formed between the second baffle 44 and the third baffle 45, the first baffle 43 is adjacent to one side of the push rod 32, and at least part of the push rod motor 31 is accommodated between the second baffle 44 and the third baffle 45.

So set up, can make between first baffle 43 and the push rod 32 more press close to, second baffle 44 and third baffle 45 also can be more close to with push rod motor 31, reduced the space waste who holds chamber 13 to make the space in air inlet chamber 12 bigger, improved the smoking effect.

In particular, in the embodiment of the present application, the first baffle 43 is recessed toward one side of the accommodating chamber 13 with respect to the third baffle 45.

Specifically, the first barrier 43, the second barrier 44, and the third barrier 45 are arranged in a zigzag shape. Specifically, the first baffle 43 is parallel or not parallel to the third baffle 45, and the second baffle 44 is disposed obliquely with respect to the first baffle 43 and the third baffle 45. More specifically, the angle α1 between the first baffle 43 and the second baffle 44 is greater than 90 degrees, and the angle α2 between the second baffle 44 and the third baffle 45 is greater than 90 degrees.

Further, the air intake chamber 12 further includes an air intake plate 60, the oil baffle 40 further includes a fourth baffle 46, the fourth baffle 46 is connected to a side of the first baffle 43 near the air intake 11, a third bending portion is formed between the fourth baffle 46 and the first baffle 43, and one end of the air intake plate 60 extends to the fourth baffle 46.

The air inlet plate 60 is typically disposed on the opposite side of the air inlet 11, and is capable of directing the oil fumes entering the air inlet chamber 12 from the air inlet 11, and also capable of directing the oil fumes into the underlying oil cup.

In order to achieve better guiding effect, the length of the air inlet plate 60 generally has a certain design requirement, so the position of the oil baffle 40 is just located at one side of the air inlet 11 along the direction intersecting with the flowing direction of the flue gas, therefore, the oil baffle 40 is provided with the fourth baffle 46, and a third bending part is formed between the fourth baffle 46 and the first baffle 43, so that interference of the oil baffle 40 on the air inlet plate 60 in the length direction of the air inlet plate 60 can be reduced. In addition, since one end of the air inlet plate 60 extends to the fourth baffle 46, the air inlet plate can be well connected with the fourth baffle 46, and the oil smoke is reduced from flowing away from the gap between the air inlet plate 60 of the kitchen ventilator and the fourth baffle 46, so that the smoking effect is improved.

In particular, in the embodiment of the present application, the fourth baffle 46 is recessed toward one side of the accommodating chamber 13 with respect to the first baffle 43.

In some embodiments, the oil baffle 40 is configured to gradually narrow the air intake chamber 12 in the direction of the flue gas flow.

The gradual narrowing of the air intake chamber 12 refers to the gradual decrease in the size of the air intake chamber 12 in a direction perpendicular to the flow direction of the flue gas, i.e., in the horizontal direction as shown in fig. 3.

The oil baffle 40 is configured to gradually narrow the air inlet chamber 12, which may be represented by the fact that the oil baffle 40 is inclined toward the center of the air inlet chamber 12 to gradually narrow the air inlet chamber 12, or the oil baffle 40 itself may be specially configured to be biased toward the center of the air inlet chamber 12 to gradually narrow the air inlet chamber 12.

Optionally, the oil baffle 40 is stepped in the direction of the flue gas flow to gradually narrow the air inlet chamber 12.

Specifically, the distance between the oil baffle 40 and the side plate 18 increases gradually in the direction of the flow of the flue gas so as to narrow the air intake chamber 12 gradually. For example, the distance between the fourth baffle 46 and the side plate 18 is smaller than the distance between the first baffle 43 and the side plate 18, and the distance between the first baffle 43 and the side plate 18 is smaller than the distance between the third baffle 45 and the side plate 18.

In other embodiments, the oil baffle 40 may be provided as a whole inclined plate-like structure inclined in a direction away from the air inlet 11.

By arranging the baffle 40 along the flow direction of the smoke, the air inlet cavity 12 is gradually narrowed, so that the smoke can be guided to gather in a direction away from the air inlet 11, the smoke is more favorable for sucking, and the smoke sucking effect is better.

In some embodiments, the oil baffle 40 is further provided with a via hole 47, and the via hole 47 is used for routing the driving mechanism 30.

Specifically, the via hole 47 may be formed on the third baffle 45. The wire through hole 47 is used for penetrating the power wire of the driving mechanism 30.

Further, in order to reduce the entry of soot from the via hole 30 into the accommodating chamber 13, a sealing structure may be provided between the inner wall of the via hole 30 and the wiring of the driving mechanism 30. Specifically, a rubber plug is provided between the inner wall of the via hole 30 and the wiring of the driving mechanism 30. The rubber plug is simple in mode, convenient to install and good in sealing effect.

Based on the same inventive concept, the present application also provides a smoke machine, including the smoke exhaust structure 100 in any of the above embodiments.

The smoke ventilator, namely the smoke ventilator, can suck the kitchen fume or the indoor fume and discharge the fume to the external space.

In addition, the application also provides an air conditioner smoke machine 200, which comprises the smoke discharging structure 100 in any embodiment.

The air conditioning ventilator 200 may also include an air conditioning structure that is capable of cooling the kitchen.

In addition, the application also provides an integrated kitchen range, which comprises the smoke exhausting structure 100 in any embodiment.

The integrated kitchen can also include kitchen body, sterilizer, air conditioner structure etc..

In the above-mentioned range hood, air conditioner range hood 200 and integrated kitchen, through forming the holding chamber 13 separated from the air inlet chamber 12 in the casing 10 of the smoke exhaust structure 100, and placing the driving mechanism 30 in the holding chamber 13, the smoke can be concentrated in the air inlet chamber 12 for circulation, and the smoke is reduced to accumulate on the driving mechanism 30, so that the driving mechanism 30 can be used normally, and the service life of the driving mechanism 30 is prolonged.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
