The fan 12 is arranged in the shell 1, when the smoke collecting device is in a working state, the first smoke inlet d1 is opened, the second smoke inlet d2 is exposed below the shell, and the fan is started to enable oil smoke to be sucked into the shell 1 from the first smoke inlet d1 and the second smoke inlet d2, so that a double smoking mode is realized.
The driver 41 and the transmission component driven by the driver 41 are arranged in the shell 1, the transmission component is in transmission connection with the smoke collecting cover 2 and the smoke collecting plate 3, under the action of the driver 41, the transmission component can synchronously drive the smoke collecting plate 3 to rotate and the smoke collecting cover 2 to lift, so that the smoke collecting plate 3 is opened to open the first smoke inlet d1 and expose the smoke collecting cover 2 below the shell, or the smoke collecting plate 3 is closed to close the first smoke inlet d1 and the smoke collecting cover 2 to be hidden in the shell, the former is the working state of the smoke collecting device, and the latter is the shutdown state of the smoke collecting device.
In this embodiment, the smoke baffle 3 and the smoke collecting hood 2 share the same driver 41 as a power source for rotation and lifting, and the same transmission assembly is used for driving.
In view of the production cost, the material cost and the processing cost of the production and manufacture can be reduced compared with the prior art in which the smoke baffle 3 and the smoke collecting hood 2 are each provided with a set of transmission mechanism and actuator 41.
From the perspective of product simplification, compare two sets of drive mechanism in prior art casing, the transmission subassembly that this embodiment set up can realize by a wide margin in the structure and refine, and the spare part of structure constitutes less, and the fault rate when then running is lower, therefore this embodiment has more reliable and stable product force than prior art.
From the perspective of space layout in the casing, in the prior art, two drivers and two transmission mechanisms need to be spatially laid out in the casing, but in this embodiment, only one driver 41 and one transmission assembly need to be spatially laid out, which not only saves space occupied in the casing 1, but also is beneficial to the positions and space layout of other parts in the casing 1, and optimizes the overall space layout in the casing 1.
From the angle of user's use experience, compare in prior art, rotation, the lift of collection petticoat pipe of keeping off the cigarette board need control alone, in this embodiment, the user only need start the rotation that driver 41 can synchronous drive keeps off cigarette board 3 and the lift of collection petticoat pipe 2, control more conveniently for the user can obtain better use experience.
Referring to fig. 3 and 4, for the transmission assembly, the transmission assembly includes a gear set and a circular arc rack 42, wherein a single gear is driven by a driver 41, one end of the circular arc rack 42 is connected with the smoke baffle 3, and the circular arc rack 42 is engaged with one gear of the gear set. The gear set drives the circular arc rack 42 to drive the smoke baffle 3 to rotate around the rotation axis of the circular arc rack 42 under the driving of the driver 41, so that the first smoke inlet d1 can be opened or the first smoke inlet d1 can be closed.
The transmission assembly may also use a single gear instead of a gear set, in which embodiment the driver 41 is coupled to the shaft of a single gear, which is in meshed engagement with the circular rack 42.
It should be noted that, in the technical scheme of the prior art about the smoke baffle driving, a telescopic push rod connected with the smoke baffle is arranged in the casing, the telescopic push rod can drive the smoke baffle to rotate through telescopic movement and rotation of the telescopic push rod, however, the smoke baffle has the requirement of smoke collection, and the maximum angle of rotation has the requirement of original length and maximum extension length of the telescopic push rod, so that in the prior art, the casing is required to be provided with matched depth space in the front-back direction for assembling the telescopic push rod, thereby leading to thicker thickness of the smoke collecting device in the front-back direction.
In the present embodiment, the circular arc rack 42 rotates around the rotation axis of the smoke baffle 3 during the transmission of the smoke baffle 3, and does not depend on the depth space in the front-rear direction, so there is no specific requirement on the thickness of the casing 1 in the front-rear direction, so that the smoke collecting device in the present embodiment can realize an ultrathin structure arrangement on the whole, and the space occupied by the smoke collecting device can be greatly compressed.
For the part of the transmission assembly for driving the fume collecting hood, in the embodiment, the transmission assembly further comprises a linear rack 43, the linear rack 43 extends vertically and is connected with the fume collecting hood 2, the linear rack 43 is in meshed connection with the other gear of the gear set in the embodiment of the transmission assembly provided with the gear set, and the linear rack 43 is in meshed connection with the single gear in the embodiment of the transmission assembly provided with the single gear. The transmission assembly of the embodiment is in meshed connection with a single gear or a gear set through the circular arc rack 42 and the linear rack 43, and can synchronously drive the rotation of the smoke baffle plate 3 and the lifting of the smoke collecting hood 2 under the condition of arranging the single driver 41.
In the prior art, since the depth space is required to be set inside the casing 1 to install the telescopic push rod, the front and rear thickness of the casing 1 is thicker, the smoke baffle 3 is not required to be set too large to avoid the risk of collision in the process of opening the smoke baffle 3 by rotation, and thus the size setting of the smoke baffle 3 is limited, i.e. the size of the first smoke inlet d1 on the bottom plate 11 of the casing 1 is also limited. In this case, the bottom plate 11 of the casing 1 has a large-area solid surface, so that during cooking, a part of the oil smoke directly enters the first smoke inlet d1 in the rising process of the oil smoke, and the other part of the oil smoke impacts the solid surface and then enters the first smoke inlet d1 along the solid surface, thereby prolonging the rising path of the oil smoke and leading to poor smoking efficiency.
Referring to fig. 3, 4 and fig. 5 in combination, in the present embodiment, the transmission mechanism of the smoke baffle 3 is based on the circular arc rack 42, so that the front and rear thickness of the casing 1 can be set thinner, that is, the structure of the casing 1 is ultrathin, on the basis, the size of the smoke baffle 3 is not limited, so that the area of the smoke baffle 3 is substantially the same as the area of the bottom plate 11 of the casing 1, and then the first smoke inlet d1 can substantially cover the bottom plate 11 of the casing 1. When cooking, the oil smoke rises in-process and can directly enter the first smoke inlet d1 along the vertical upward shortest path, so that the smoke inlet efficiency of the first smoke inlet d1 can be improved.
It should be noted that, in the prior art, since the first smoke inlet d1 and the second smoke inlet d2 are spaced apart by a large area of the solid surface on the bottom plate 11 of the chassis 1 in the front-rear direction, the smoke baffle 3 basically has a smoke collecting effect on the smoke entering the first smoke inlet d1 in the open state, and has a very small smoke collecting effect on the smoke entering the second smoke inlet d2. In this embodiment, the first smoke inlet d1 substantially covers the bottom plate 11 of the casing 1, so that the first smoke inlet d1 and the second smoke inlet d2 are adjacent in the front-rear direction, and therefore, the smoke baffle 3 has a better smoke collecting effect on the first smoke inlet d1 and the second smoke inlet d2, so as to further improve smoke inlet efficiency and avoid escape of smoke.
With continued reference to fig. 3 and 4, in the present embodiment, the transmission assembly is provided with a dual-gear set, specifically, the gear set includes a first gear 44 and a second gear 45, where the first gear 44 is engaged with the circular arc rack 42, the second gear 45 is engaged with the linear rack 43, and the driver 41 is connected with a rotating shaft of the first gear 44 or the second gear 45.
In one embodiment, the first gear 44 has a larger diameter than the second gear 45, and the driver 41 is coupled to the rotation shaft of the first gear 44. Since the diameter of the first gear 44 is larger than that of the second gear 45, the rotation speed of the rotation shaft of the first gear 44 is smaller than that of the second gear 45, so that the power requirement of the driver 41 can be reduced. In another embodiment, the second gear 45 has a larger diameter than the first gear 44, and the driver 41 is connected to the rotation shaft of the second gear 45.
In the present embodiment, the first gear 44 and the second gear 45 have a vertical positional relationship, and both may be Xu Cuokai in the front-rear direction, and only the vertical positional relationship is required. In this arrangement, the distance between the circular arc rack 42 engaged with the first gear 44 and the rotation axis of the smoke barrier 3 is maximized, that is, the arm of force is maximized, so that the power requirement of the circular arc rack 42 for pushing the smoke barrier 3 can be reduced, thereby reducing the power requirement of the driver 41.
The transmission assembly of this embodiment, through the diameter relation of the first gear 44, the second gear 45, the setting of positional relationship, can reduce the power requirement to the driver 41, not only can reduce cost, can also be more miniature model type, be favorable to the space arrangement in the casing 1.
In the present embodiment, the second gear 45 has a larger width than the first gear 44, so that the first gear 44 and the linear rack 43 are offset from each other in the left-right direction to avoid interference.
The transmission assembly is externally provided with a housing 46. In one embodiment, a single gear is disposed within the housing 46, and in another embodiment, a gear set is disposed within the housing 46. Specifically, in this embodiment, the first gear 44 and the second gear 45 are disposed in the housing 46, the housing 46 is provided with a first opening 46a and a second opening 46b, wherein a portion of the first gear 44 exposes the first opening 46a and the circular arc rack 42 to be in meshed connection, and a portion of the second gear 45 exposes the second opening 46b and the linear rack 43 to be in meshed connection. The housing 46 covers the first gear 44 and the second gear 45, so that oil stains on the first gear 44 and the second gear can be reduced, and better oil resistance is achieved.
In this embodiment, the housing 46 includes a first half shell 461 and a second half shell 462 that are assembled into the housing 46. Wherein the second half-shell 462 is provided with a connecting lug 4621, the connecting lug 4621 being connected to the inner side of the housing 1.
In the present embodiment, the driver 41 is provided as a motor which is mounted and fixed to the housing 46.
In this embodiment, one side of the smoke barrier 3 is provided with a rotary connecting member 31 rotatably connected to the casing 1, and the other side is connected to a circular arc rack 42. Because the arc rack 42 rotates around the rotation axis of the smoke baffle 3 in the transmission process, the acting force of the arc rack 42 on the smoke baffle 3 is always vertical to the plate surface of the smoke baffle, the arc rack 42 not only plays a role in pushing the smoke baffle 3 to rotate, but also plays a supporting role on the smoke baffle 3 after the smoke baffle 3 is opened, and therefore, the smoke baffle 3 only needs to be provided with the rotating connecting piece 31 to match the rotation of the rotating connecting piece. In the prior art, based on the action mode of the telescopic push rod on the smoke baffle plate 3, the smoke baffle plate 3 is further required to be provided with a supporting arm structure for supporting the smoke baffle plate 3, and compared with the prior art, the embodiment is more simplified in structure.
The biting teeth of the circular arc rack 42 are formed on the outer arc surface thereof, at least one side of the circular arc rack 42 is provided with a step structure 421, the step structure 421 extends along the extending direction of the circular arc rack, in one embodiment, the step structure 421 can be abutted against the side surface of the gear, and in another embodiment, the step structure 421 can be abutted against the corresponding gear side surface of the gear set. Specifically, in this embodiment, the step structure 421 may abut against a side surface of the first gear 44, so as to limit the axial relative displacement between the circular arc rack 42 and the first gear 44, so as to avoid occurrence of a situation that the circular arc rack 42 and the first gear 44 mesh and slip, in this embodiment, the circular arc rack 42 is only provided with the step structure 421 on one side far away from the connecting piece 31, or may be provided with the step structure 421 on the other side of the circular arc rack 42, or both sides of the circular arc rack 42 are provided with the step structure 421. One end of the circular arc rack 42 is provided with a connecting seat 422, and the connecting seat 422 is connected to the inner surface of the smoke barrier 3.

The third smoke inlet d3 communicated with the inside and the outside of the smoke collecting cover 2 is formed in the upper groove wall of the smoke collecting groove 21, and the smoke entering the smoke collecting groove 21 enters the smoke collecting cover 2 through the third smoke inlet d3, so that the smoke collecting cover 2 has a good smoke collecting effect. In addition, the third smoke inlet d3 is arranged on the upper groove wall of the smoke collecting groove 21, so that a user can not observe the smoke collecting groove during cooking, and the smoke collecting cover 2 is attractive in whole.
Referring to fig. 2, in this embodiment, a vertically extending slide rail 51 is disposed in the casing 1, and at least one sliding connector 52 slidably connected to the slide rail 51 is disposed on the fume collecting hood 2, so that the fume collecting hood 2 can move up and down along the casing 1, and the sliding connector 52 can be single, so that a certain length of the single sliding connector 52 is required, and a plurality of sliding connectors can also be disposed, and vertically spaced apart. In addition, the slide rail 51 may be provided to the hood 2, and the slide connector 52 may be provided to the housing 1.
