One side of the smoke guide plate 210 is rotatably installed at the housing 200 such that the smoke guide plate 210 can be turned over to cover the smoke outlet 221 and turned over to open the smoke outlet 221. The smoke guide plate 210 may be disposed at any side of the smoke outlet 221, and for convenience of understanding, in the following embodiments, the smoke guide plate 210 is disposed on the upper side of the smoke outlet 221 in a movable manner, that is, the smoke guide plate 210 has a movable stroke of being turned up and down. When the smoke guide plate 210 is opened to a set angle relative to the smoke outlet 221, the smoke guide plate 210 and the smoke collection cavity 220 together form a negative pressure region, so that smoke generated at the cooking bench can be sucked into the smoke collection cavity 220.
The flap mechanism 100 is disposed on the housing 200 and is used to drive the smoke guide 210 to switch between opening the smoke outlet 221 and closing the smoke outlet 221.
Since the main utility model of the present invention is an improvement of the plate turnover mechanism 100, the plate turnover mechanism 100 will be mainly explained with reference to the drawings.
Referring to fig. 2 and fig. 4, in the present embodiment, the plate turnover mechanism 100 includes a base 110, a piston rod 120, a connecting pipe 130 and a driving assembly 140, wherein the base 110 is configured to be mounted to a smoke collection cavity 220, and the base 110 is provided with a first opening 111, a second opening 112 and a piston cavity communicating the first opening 111 and the second opening 112; one end of the piston rod 120 is slidably mounted in the piston cavity from the first opening 111 and forms a sealing fit with the inner cavity wall of the piston cavity, and the other end of the piston rod 120 is used for being connected with the smoke guide plate 210, so that when the piston rod 120 slides relative to the piston cavity, the smoke guide plate 210 is driven to open or close the smoke exhaust port 221; the connecting pipe 130 is connected with the second opening 112 in a sealing manner and is communicated with the piston cavity; the driving assembly 140 is used for adjusting the pressure in the connecting tube 130 so that the piston rod 120 slides relative to the piston cavity. Wherein, at least part of the connecting tube 130 can be bent.
In the technical solution provided by the present invention, the connecting pipe 130 can divide the panel turnover mechanism 100 into two installation components, namely, a seat body 110, a piston rod 120 and a driving assembly 140, which are mutually matched; by defining the specific shape of the connecting tube 130, the two mounting members can be respectively mounted at different orientations, and then the flap mechanism 100 is suitable for different mounting scenes; and the two mounting components can be respectively mounted at different positions, which is beneficial to reducing the space occupation of the smoke collecting cavity 220 by the flap mechanism 100, thereby being beneficial to improving the structural universality and the mounting convenience of the flap mechanism 100.
It can be understood that the seat body 110 can be installed at any suitable position in the smoke collecting cavity 220, but based on the consideration of reducing the space occupation and simplifying the structure, the seat body 110 in this embodiment is disposed as close to the smoke guide plate 210 as possible, so that the size and the moving stroke of the piston rod 120 can be effectively shortened, and the requirements on the structural strength and the dynamic strength of the piston rod 120 can be reduced. Specifically, when the smoke guide plate 210 is disposed above the smoke discharge port 221, the flap mechanism 100 may be optionally disposed on the upper cavity wall of the smoke collection cavity 220; and further, the upper chamber wall of smoke collecting cavity 220 can be set up to be the slope setting downwards gradually along the flue gas circulation direction, can form the water conservancy diversion face of an slope, concentrates on with the flue gas water conservancy diversion downwards, helps improving the exhaust efficiency of flue gas, and can avoid the backward flow of flue gas to a certain extent.
The specific installation manner between the seat body 110 and the upper cavity wall of the smoke collecting cavity 220 is not limited, for example, a threaded hole may be provided at one of the joints of the seat body and the smoke collecting cavity, and a screw fitting adapted to the threaded hole may be provided at the other joint for screw fastening; or a clamping part is arranged at one of the connection parts of the two parts, and a clamping groove or a clamping hole matched with the clamping part is arranged at the other part for clamping and fixing; or one of the two connecting parts is provided with a magnetic attraction piece, and the other one is provided with a fitting piece which is attracted by the magnetic attraction piece to adsorb and fix and the like.
The specific representation form of the seat body 110 is not limited by the design, and the seat body 110 can be set to any suitable shape and size according to the actual requirement. In this embodiment, the outer contour of the seat body 110 is substantially cylindrical and has an arc-shaped outer surface, thereby helping to reduce the flow resistance of the passing smoke.
The specific opening positions of the first opening 111 and the second opening 112 on the seat body 110 are also not limited, and the specific opening positions of the first opening 111 and the second opening 112 can substantially determine the extending direction of the piston cavity, that is, the sliding direction of the piston rod 120. In a particular application, the first opening 111 may be disposed closer to the smoke guide plate 210 than the second opening 112, which helps to reduce the distance between the piston rod 120 and the smoke guide plate 210.
The piston rod 120 has a piston end and a driving end which are oppositely arranged, the driving end of the piston rod 120 is connected to the smoke guide plate 210, and the piston end of the piston rod 120 is installed in the piston cavity. In order to achieve a sealing fit between the piston rod 120 and the piston cavity, in an embodiment, an outer dimension and a shape of the piston end of the piston rod 120 may be set to be correspondingly adapted to the dimension and the shape of the piston cavity, taking the piston end of the piston rod 120 as an example, a cross-sectional shape of the piston end may be specifically set to be circular, oval, polygonal or other irregular shapes, and in this embodiment, a cross-section of the piston end of the piston rod 120 is set to be substantially circular. In another embodiment, the piston end of the piston rod 120 may be made of an elastic material, and have an elastic deformation capability, so as to apply a certain abutting force to the inner cavity wall of the piston cavity.
One end of the connecting tube 130 is hermetically connected to the second opening 112 of the seat body 110 and is communicated with the piston cavity. Specifically, one end of the connecting tube 130 can be sleeved with the seat body 110 adjacent to the second opening 112, for example, the connecting tube 130 is inserted into the second opening 112; a sealing ring can be further arranged at the sleeve joint of the two, so that the sealing effect is enhanced; alternatively, the connecting pipe 130 may be connected to the second opening 112 via a connecting ring, and similarly, a sealing ring may be disposed at the joint of the three.
In an embodiment, at least a portion of the connecting tube 130 is bendable, wherein the bendable portion of the connecting tube 130 can be embodied to be bent at least a specific angle, such as the first bending state, the second bending state and the third bending state shown in fig. 4 to 6; it may also be shown as being adjustable at will over a range of angles, for example, fig. 4 and as shown in fig. 6, to any one of the first and third bending states.
The flexible arrangement of the connecting tube 130 makes the installation orientation between the housing 110 and the piston rod 120, and the driving assembly 140 have more options, which is suitable for smoke collecting cavities 220 with different expressions; moreover, the base 110, the piston rod 120 and the driving element 140 have more innovative freedom in structural design.
In order to realize the flexible arrangement of the connection tube 130, in an embodiment, the connection tube 130 is made of a flexible material. The flexible material can be elastic material or any other material capable of bending and deforming. For example, it may be made of rubber, silicone, oilpaper, etc. The flexible material makes the local deformation degree of the connection tube 130 different according to the magnitude and direction of the stress, for example, when one side wall of the connection tube 130 is pressed and the other side opposite to the side wall is pulled, the connection tube 130 is bent and deformed toward the pressed side. The specific mechanism is not described in detail here.
The ability of a material to resist bending deformation within the elastic limit can be characterized by the flexural modulus, also known as the flexural modulus, which refers to the bending stress versus the strain resulting from bending. It can be understood that when the connection pipe 130 is made of a material having a small bending modulus, the material property of the material itself is sufficient to support the connection pipe 130 to perform bending deformation in a large angle range, such as a hose made of rubber; on the contrary, when the bending modulus of the material of the connecting pipe 130 is large, the bending angle of the connecting pipe 130 is limited, and therefore, the connecting pipe 130 may further have at least two side wall sections sequentially connected along the length direction thereof, and each two adjacent side wall sections may be foldable, so as to further enhance the bending effect, such as corrugated pipes and other pipes.
Further, referring to fig. 4 to 5, in an embodiment, the connecting tube 130 includes a first tube segment 131, a second tube segment 132, and a bent tube segment 133 connecting the first tube segment 131 and the second tube segment 132; the first pipe segment 131 is in communication with the second opening 112, and the second pipe segment 132 is connected to the driving assembly 140. Specifically, the first tube segment 131 and the second tube segment 132 may be arranged to form a crossing arrangement with a set included angle according to actual needs (see fig. 4 and 5), or may be arranged to form a parallel arrangement with a space (see fig. 6). The segmented connecting tube 130 facilitates different functional or structural features at different tube segments, e.g., the first tube segment 131 may be shaped to conform to the shape of the wall along the upper wall of the smoke collection chamber 220; the second pipe section 132 can be disposed according to the specific installation orientation between the driving assembly 140 and the seat body 110; the bent pipe section 133 may achieve the above-described bent arrangement of the connection pipe 130. In addition, the connecting pipe 130 is provided in segments, so that the first pipe segment 131, the second pipe segment 132 and the bent pipe segment 133 are independent of each other and can be independently disassembled and replaced without affecting the rest pipe segments.
Based on the above, further, in an embodiment, the bending modulus of the first pipe segment 131 and the second pipe segment 132 is set to be greater than the bending modulus of the bent pipe segment 133. With the arrangement, the bending pipe section 133 can realize that the connecting pipe 130 can be bent according to actual needs; meanwhile, the freedom of movement of the first pipe section 131 and the second pipe section 132 is reduced, so that the bent pipe section 133 is sufficiently supported, and the overall structural stability of the panel turnover mechanism 100 is improved.
In addition, the piston end of the piston rod 120 divides the piston cavity into a first chamber disposed near the driving end of the piston rod 120 and a second chamber disposed in communication with the connecting tube 130. The driving assembly 140 is configured to act on the connection pipe 130, so that the pressure inside the connection pipe 130 changes, and thus the pressure in the second chamber of the piston chamber changes, and a pressure action or a pulling action is applied to the piston end of the piston rod 120, so that the piston rod 120 slides relative to the piston chamber.
It should be noted that, when the pressure inside the connecting pipe 130 is lower than the external pressure, a pulling force is applied to the piston end of the piston rod 120, so that the smoke guide plate 210 covers the smoke outlet 221; on the contrary, when the pressure inside the connection pipe 130 is higher than the external pressure, the piston end of the piston rod 120 is pressurized, so that the smoke guide plate 210 opens the smoke outlet 221. That is, the driving assembly 140 may drive the piston rod 120 to slide back and forth, but for convenience of understanding, the following description will take the driving assembly 140 to drive the piston rod 120 to slide in one direction, for example, the driving piston rod 120 moves to drive the smoke guide plate 210 to open the smoke outlet 221; it should be noted that the moving stroke of the piston rod 120 driving the smoke guide plate 210 to cover the smoke outlet 221 may be realized by the driving of the driving assembly 140, or may be realized by manual operation of a user.
In one embodiment, the driving assembly 140 may include an air pump having an air transmission port, and the connecting tube 130 is communicated with the second opening 112 and the air transmission port respectively and forms a sealing fit, so that the connecting tube 130 and the second chamber of the piston chamber have sufficient air tightness. When the air pump is controlled to blow air into the connecting pipe 130, pressure can be applied to the piston end of the piston rod 120, so that the piston rod 120 slides to drive the smoke guide plate 210 to open the smoke outlet 221.
In one embodiment, the connection tube 130 contains hydraulic oil; the driving assembly 140 is configured to drive the hydraulic oil to move toward the piston rod 120, so as to push the piston rod 120 to slide relative to the piston cavity. In this case, the driving assembly 140 may be the air pump described above, and will not be described in detail herein; the push plate can also be composed of a driver and a push plate movably installed in the connecting pipe 130, specifically, the push plate can divide the connecting pipe 130 into two pipe sections, wherein the pipe section communicated with the piston cavity contains hydraulic oil, and the driver drives the push plate to move along the length direction of the connecting pipe 130, so as to push the hydraulic oil to move towards the piston cavity. The driver can be a linear air cylinder, or a driving motor and a transmission component such as a gear rack mechanism, and the details are not described here.
In one embodiment, the driving assembly 140 is formed with a fluid passage port for passing hydraulic fluid therethrough; the connecting tube 130 is respectively communicated with the second opening 112 and the liquid passing port. At this time, the driving assembly 140 may include a driving motor, a hydraulic pump and a hydraulic oil tank, and under the driving of the driving motor, the hydraulic pump draws hydraulic oil from the hydraulic oil tank and discharges the hydraulic oil into the connecting pipe 130 through the liquid port, so as to push the piston rod 120.
Further, in an embodiment, the flap mechanism 100 further includes a reversing assembly 150, and the reversing assembly 150 is configured to be connected to the piston rod 120 and the smoke guide plate 210, respectively, so as to convert the sliding of the piston rod 120 relative to the piston cavity into the sliding of the smoke guide plate 210 to open or close the smoke exhaust port 221. Because the sliding of the piston rod 120 relative to the piston cavity is linear, when the piston rod 120 is directly connected with the smoke guide plate 210, the smoke guide plate 210 can only be driven to turn over to a certain angle; through setting up switching-over subassembly 150, can convert the linear activity of piston pipe into the arc activity of leading cigarette board 210 for the upset angle scope increase of leading cigarette board 210 helps improving the practicality of integrated kitchen.
The specific scheme of the reversing assembly 150 is various, for example, the reversing assembly 150 can be provided as a crank-slider mechanism; in this embodiment, the reversing assembly 150 includes a plurality of links pivotally connected to each other, which helps to simplify the structural complexity of the turnover mechanism and reduce the manufacturing cost. Specifically, referring to fig. 2 and fig. 3, the reversing mechanism includes a first connecting rod 151 and a second connecting rod 152, wherein one end of the first connecting rod 151 is pivotally connected to the driving end of the piston rod 120; one end of the second link 152 is pivotally connected to the panel surface of the smoke guide 210, the other end of the second link 152 is pivotally connected to the housing 200, and the first link 151 is movably connected to a position of the second link 152 close to the smoke guide 210. The second link 152 may be disposed in an arc shape to reduce interference with the smoke guide 210 and the housing 200.
When the panel turnover mechanism 100 is mounted on the integrated stove, in an embodiment, the housing 200 is further formed with a mounting cavity 230, and the mounting cavity 230 is provided with a mounting hole communicated to the smoke collecting cavity 220; the base 110 and the piston rod 120 are accommodated in the smoke collecting cavity 220, the driving assembly 140 is accommodated in the mounting cavity 230, and the connecting pipe 130 is inserted into the mounting hole and is in sealing fit with the mounting hole. The installation cavity 230 may be, for example, an existing cavity for installing an electric control system and a display device of the integrated cooker, or an additionally formed cavity. The seat body 110, the piston rod 120 and the driving component 140 are separately installed, so that on one hand, the occupied space of the whole smoke collection cavity 220 of the panel turnover mechanism 100 can be reduced, and on the other hand, the pollution of oil smoke and the damage to the driving component 140 can be avoided.
Further, in one embodiment, the connection tube 130 forms a sealing fit with the connection of the mounting hole. Specifically, the outer diameter of the connection tube 130 may be slightly larger than the bore diameter of the mounting hole, so that an interference fit is formed between the connection tube 130 and the mounting hole; the connecting part of the connecting pipe 130 and the mounting hole can be further made of elastic materials, so that when elastic deformation is generated, a butting force is generated on the hole wall of the mounting hole, and the sealing effect of the connecting pipe and the mounting hole is strengthened; of course, a sealing ring may be directly added at the connection between the connection tube 130 and the mounting hole, and will not be described in detail here.
