Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and are not to be construed as limiting the present utility model.

The following disclosure provides many different embodiments, or examples, for implementing different features of the utility model. In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the utility model. Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present utility model provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.

Referring to fig. 1 and 2, a smoke evacuation system 100 according to an embodiment of the utility model is used in a cooking apparatus 200. The fume extraction system 100 includes a fume extraction assembly 110 and a purification assembly 120. The fume extractor assembly 110 includes a blower 111. The fan 111 is used to guide the flow of the soot. The cleaning assembly 120 includes a supergravity structure 121 and an electrostatic structure 141. The supergravity structure 121 communicates with the electrostatic structure 141. The electrostatic structure 141 communicates with the blower 111. The super gravity structure 121 is formed with an adsorption region. The electrostatic structures 141 are used to collect charged oil droplets in the soot. In the case where the oil smoke passes through the adsorption area in the first direction, oil droplets in the oil smoke are adsorbed by the liquid droplets in the adsorption area and fall down in the second direction. The first direction and the second direction are different.

Above-mentioned smoke evacuation system 100 can collect charged oil drop granule in the oil smoke through static structure 141, can reduce the oil drop content in the oil smoke, through forming adsorption area, when the oil smoke passes through adsorption area along first direction, the oil drop in the oil smoke can be adsorbed by the liquid drop and increase self weight, and then makes the gravity of oil drop be greater than self buoyancy and fall along the second direction to separate the oil drop from the oil smoke, realize the comprehensive purifying effect to the oil smoke.

Referring to fig. 1 and 2, a smoke evacuation system 100 includes a smoke port 101. The blower 111 may be activated so as to draw the cooking fumes generated by the cooking apparatus 200 into the fume exhaust system 100 from the fume exhaust port 101 and guide the flow of the fumes within the fume exhaust system 100. During the flow of the oil smoke, the oil smoke may flow through the electrostatic structure 141 and the super-gravity structure 121 in sequence, so that the electrostatic structure 141 and the super-gravity structure 121 can sequentially purify oil drops in the oil smoke. The plurality of smoking openings 101 can be sequentially arranged along the arc concave surface, so that the plurality of smoking openings 101 can be close to a smoke source for generating the oil smoke on the cooking device 200, and the smoking openings are favorable for sucking all the oil smoke discharged by the cooking device 200.

Specifically, referring to fig. 3, fig. 3 illustrates some relevant components of the supergravity structure 121. In fig. 3, the supergravity structure 121 includes a supergravity inlet 1212 and a supergravity outlet 1213. In the case where the oil smoke passes through the super gravity structure 121, the oil smoke may flow into the super gravity structure 121 along the super gravity inlet 1212 and flow out of the super gravity structure 121 along the super gravity outlet 1213. In fig. 3, a space corresponding to a dotted line frame is an adsorption area, and the adsorption area is denoted by M.

During the flow of the soot from the high gravity inlet 1212 to the high gravity outlet 1213, it passes through the adsorption region located within the high gravity structure 121. Referring to fig. 4, a large number of droplets are uniformly distributed in the adsorption area, and when the oil smoke passes through the adsorption area along the first direction, the droplets in the oil smoke collide with the droplets and can be adsorbed on the droplets, so that the overall weight of the droplets can be increased under the condition of consuming the kinetic energy of the droplets. Finally, the oil drops can fall down along a second direction different from the first direction due to the fact that the integral weight is larger than the self buoyancy, so that the oil drops are separated from the oil smoke, the content of the oil drops in the oil smoke is reduced finally, and the effect of purifying the oil smoke is achieved. In fig. 4, oil droplets in the oil smoke are denoted by S1, liquid droplets located in the adsorption region are denoted by S2, and oil droplets adsorbed by the liquid droplets are denoted by S3. The first direction is denoted A1 and the second direction is denoted A2.

In addition, purifying the oil smoke through the adsorption area can also be beneficial to reducing pm2.5 of the oil smoke, and the temperature of the discharged oil smoke can be reduced, so that the device can be suitable for application scenes with higher requirements on oil smoke emission.

In addition, the first direction and the second direction are different, and an included angle formed by the first direction and the second direction may be greater than or equal to a first preset angle. In some embodiments, referring to fig. 4, the first direction is vertically upward, the second direction is vertically downward, and an included angle formed by the first direction and the second direction is 180 degrees. In other embodiments, the first direction may be a horizontal direction, the second direction may be a vertical downward direction, and an included angle formed by the first direction and the second direction is 90 degrees. On the basis of the above, the first preset angle may be 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, 180 degrees. It will be appreciated that the flow direction of the oil smoke may be changed by the specific configuration of the supergravity structure 121, and the drop direction of the oil droplets may be substantially determined, so that the included angle formed by the first direction and the second direction may be adjusted according to specific requirements.

Referring to fig. 2 and 5, in some embodiments, the electrostatic structure 141 includes a charging member 142 and a collecting member 143. The charging member 142 is configured to provide a first charge to oil droplets passing through the charging member 142. The collecting member 143 is used for collecting oil droplets having a first charge in the oil smoke. The collector 143 is charged with a second electric charge. The first charge is one of positive and negative charges, and the second charge is the other of positive and negative charges.

Thus, the content of fine particles of the lampblack can be reduced.

Specifically, referring to fig. 2 and 5, the electrostatic structure 141 may be connected to the blower 111 through the charging member 142, and the charging member 142 and the collecting member 143 may be connected to each other. In the case where the oil smoke is guided by the blower 111 to flow into the charging member 142, the charging member 142 may provide a first charge to oil droplets in the oil smoke so that the oil droplets in the oil smoke are charged. In the case of passing through the collecting member 143, the charged droplets are adsorbed in the collecting member 143 due to the second charge of the collecting member 143 opposite to the first charge, so that the collecting member 143 can collect the charged droplets. The first charge is a positive charge and the second charge is a negative charge, or alternatively, the first charge is a negative charge and the second charge is a positive charge.

It will be appreciated that for smaller sized particles, where they are charged, they tend to deviate from the original trajectory due to the attractive interaction of the opposite charges. By arranging the charging member 142 and the collecting member 143, oil drops with smaller size in the oil smoke can be separated out, which is beneficial to reducing the content of fine particles (PM 2.5) of the oil smoke.

Referring to fig. 5, in some embodiments, the charging member 142 includes a flow guiding surface 144. The flow guide surface 144 is disposed obliquely in the charging member 142. The flow guide surface 144 serves to guide the flow of the soot through the collecting member 143.

Thus, the collection efficiency of charged oil droplets can be improved.

Specifically, in fig. 5, the flow direction of the oil smoke flowing into the charging member 142 is denoted as B1, and the flow direction of the oil smoke flowing into the collecting member 143 is denoted as B2. The inclined direction of the flow guide surface 144 is toward the set collector 143. Under the condition that the oil smoke flows into the charging member 142, the oil smoke directly impacts the guide surface 144, so that the oil drops provided with the first electric charge by the charging member 142 can flow along the inclined direction of the guide surface 144, and can move towards the collecting member 143 more easily, so that the collecting member 143 can collect the charged oil drops conveniently, and the collecting efficiency of the charged oil drops can be improved.

Referring to fig. 2, in some embodiments, the decontamination module 120 includes a diversion adapter 145. The flow guiding adaptor 145 communicates the hypergravity structure 121 and the electrostatic structure 141. The flow guiding adaptor 145 is used for changing the flow direction of the oil smoke flowing from the static structure 141 to the super gravity structure 121.

Thus, the purifying effect of the adsorption area on oil drops can be improved.

It can be understood that by changing the flow direction of the oil smoke flowing from the electrostatic structure 141 to the supergravity structure 121, the flow speed of the oil smoke can be reduced due to the change of the flow direction, and the oil smoke can more easily and gently pass through the adsorption area under the condition of entering the supergravity structure 121, so that the residence time of the oil drops in the oil smoke in the adsorption area is longer and the oil drops are more easily adsorbed by the liquid drops to separate the oil smoke, thereby being beneficial to improving the purifying effect of the adsorption area on the oil drops.

In the embodiment shown in fig. 2, the flow direction of the soot flowing out of the static structure 141 forms an angle of 90 degrees with the flow direction of the soot flowing into the supergravity structure 121. In other embodiments, the angle formed by the flow direction of the oil smoke flowing out of the static structure 141 and the flow direction of the oil smoke flowing into the super gravity structure 121 may be 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, 95 degrees, 100 degrees. The angle formed by the flow direction of the oil smoke flowing out of the static structure 141 and the flow direction of the oil smoke flowing into the super gravity structure 121 can be adjusted by changing the specific structure of the diversion adaptor 145.

Referring to fig. 3, in some embodiments, the supergravity structure 121 includes a rotating mesh 1214. The rotary web 1214 is capable of rotating along an axis of rotation. The axis of rotation is substantially parallel to the first direction. When the liquid film is attached to the rotary web 1214, the liquid film is dispersed into a plurality of liquid droplets by the rotation drive of the rotary web 1214, and is distributed in the adsorption region.

In this way, the effect of dispersing the liquid droplets in the adsorption region can be advantageously achieved.

Specifically, in fig. 3, the rotation axis is denoted as L. With the liquid film attached to the rotating mesh 1214, the smoke evacuation system 100 may control the rotating mesh 1214 to begin rotating along the axis of rotation such that the liquid film follows the rotation of the rotating mesh 1214 and generates centrifugal force. The liquid film eventually breaks off from the rotating mesh 1214 due to centrifugal force and breaks up into droplets smaller in size than the liquid film and disperses in the adsorption zone during the break-off process. The liquid drops are small in size and can reach micron-sized, the liquid drops can hover in the adsorption area after stopping moving, and a large number of liquid drops can be dispersed in the adsorption area under the condition that the rotary net 1214 breaks up a large number of liquid films into liquid drops, so that the oil drops in the oil smoke are conveniently adsorbed. In some embodiments, the liquid film may be attached to the rotating web 1214 by spraying.

In addition, the rotation axis is substantially parallel to the first direction, and an included angle formed by the rotation axis and the first direction may be smaller than or equal to a second preset angle. Referring to fig. 4, the rotation axis is parallel to the first direction, and an included angle formed by the rotation axis and the first direction is 0 degrees. On the basis of the above, the second preset angle may be 0 degree, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees. It will be appreciated that the rotary web 1214 may enable adjustment of the axis of rotation by adjustment of corresponding structures so that the axial direction of the axis of rotation may be adjusted according to particular needs.

Further, in fig. 3, a support 1218 is provided between two adjacent rotary webs 1214. The end of the support 1218 on one side is connected to one of the rotary webs 1214 and the end of the support 1218 on the other side is connected to the other rotary web 1214. In the case that the rotary net 1214 rotates, another rotary net 1214 may be driven to rotate synchronously by the support 1218, so that a problem of dynamic balance caused by inconsistent rotation when a plurality of rotary nets 1214 rotate may be avoided.

In addition, the rotary mesh 1214 may include a filler for purging. The packing may include pall rings, raschig rings. In fig. 3, the supergravity structure 121 further comprises a motor 1217.

Referring to fig. 3, in some embodiments, the supergravity structure 121 includes a spray structure 122. The spray structure 122 is used to spray the solution such that the solution adheres to the rotating web 1214 and forms a liquid film.

In this way, the extent to which droplets are uniformly distributed in the adsorption zone can be advantageously increased.

Specifically, in fig. 3, the spray structure 122 is disposed proximate to the rotating web 1214. Spray structure 122 has a plurality of spray holes 1221 formed therein. The plurality of orifices 1221 are correspondingly oriented toward the rotary web 1214. In the case where the fume exhaust system 100 pumps the solution toward the spray structure 122, the solution will be ejected toward the rotating web 1214 in response to the orientation of the nozzle 1221. As the solution approaches the rotating web 1214, the solution may break up into smaller portions, each of which may eventually adhere to the rotating web 1214 and form a liquid film.

It can be appreciated that by spraying the solution through the spraying structure 122, the liquid film attached to the rotary net 1214 can be more dispersed, so that all the liquid films can be broken up into droplets with similar sizes, and the distribution of the droplets in the adsorption area can be more uniform.

In some embodiments, the plurality of spray orifices 1221 may be uniformly spaced on the spray structure 122, which may facilitate uniform spraying of the solution onto the rotating web 1214.

Additionally, in some embodiments, the solution may include at least one of water, a surfactant, a deodorizing agent.

Referring to fig. 3, in some embodiments, the number of rotating webs 1214 is at least two. The spray pattern 122 is located between two of the rotating webs 1214. Spray structure 122 includes a plurality of spray orifices 1221. Some of the orifices 1221 are disposed adjacent one of the rotary webs 1214 and some of the orifices 1221 are disposed adjacent the other rotary web 1214.

Thus, the efficiency of purifying oil drops can be advantageously improved.

Specifically, in fig. 3, the plurality of spray holes 1221 are distributed in two rows on the spray structure 122, wherein one row of spray holes 1221 is located at one end of the spray structure 122 and the other row of spray holes 1221 is located at the other end of the spray structure 122 along the axial direction of the rotation axis. Both ends of the spray structure 122 face toward a corresponding one of the rotating webs 1214.

In one embodiment, the spray structure 122 is generally cylindrical in shape and the generatrix is parallel to the axis of rotation, with the orifices 1221 distributed in a row being disposed circumferentially around the surface of the spray structure 122 in an axial direction about the axis of rotation.

It will be appreciated that by providing the spray structure 122 at the spacing between the two rotary webs 1214, the spray structure 122 can spray the solution to both rotary webs 1214 at the same time, and the solution can be more intensively dispersed into droplets in the space between the two rotary webs 1214, thereby increasing the density of droplets in the adsorption area, and the droplets are more easily adsorbed by the droplets, thereby facilitating the improvement of the efficiency of purifying the droplets. Furthermore, it is not necessary to provide a shower structure 122 for each rotary screen 1214, which is advantageous in terms of simplification of the structure.

Referring to fig. 3, in some embodiments, the supergravity structure 121 includes a reservoir 1215. The reservoir 1215 is used to store a solution. The reservoir 1215 communicates with the adsorption zone. The reservoir 1215 is positioned in a second direction relative to the adsorption zone.

Thus, the solution can be fully utilized.

Specifically, in fig. 3, the supergravity structure 121 further includes a feed pump 1216. The feed pump 1216 is located within the reservoir 1215 and is in communication with the spray structure 122. In the event that it is desired to form droplets into the adsorption zone, the solution in the reservoir 1215 can be pumped to the spray structure 122 by controlling the liquid feed pump 1216 so that the solution is sprayed through the spray structure 122 toward the rotating web 1214.

In the case where the oil droplets are adsorbed by the liquid droplets, since the liquid storage tank 1215 is located in the second direction with respect to the adsorption region, the oil droplets adsorbed by the liquid droplets can be caused to fall into the liquid storage tank 1215 from the adsorption region in the second direction, and the solution forming the liquid droplets can fall back into the liquid storage tank 1215 again.

It can be appreciated that the liquid feeding pump 1216 can continuously pump the solution to the spraying structure 122 for adsorbing oil drops in the oil smoke, so that the solution adsorbs as many oil drops as possible by forming liquid drops, and the problem that the solution is wasted due to single use caused by direct discharge after one adsorption is avoided, thereby being beneficial to fully utilizing the solution.

Referring to fig. 6, in some embodiments, the decontamination module 120 includes a smoke evacuation adapter 123. The smoke exhausting adaptor 123 is communicated with the hypergravity structure 121. The smoke exhausting adaptor 123 is used for changing the flowing direction of the oil smoke after flowing out of the super gravity structure 121.

Thus, the recovery of the residual steam in the oil fume can be facilitated.

Specifically, in fig. 6, the smoke exhaust adaptor 123 includes a first adaptor section 1231, a second adaptor section 1232, and a smoke exhaust port 1233. The first transition segment 1231 extends along the direction A3, one end of the first transition segment 1231 is connected to the supergravity outlet 1213 and the other end is connected to the second transition segment 1232. The second adapting section 1232 extends along the A4 direction, and one end of the second adapting section 1232 is communicated with the first adapting section 1231 and the other end is communicated with the smoke outlet 1233. The A3 direction and the A4 direction form an angle such that a corner is formed at a position where the first and

second transition sections

1231 and 1232 communicate.

After the oil smoke flows out of the super-gravity structure 121 from the super-gravity outlet 1213, the oil smoke flows to the corner along the direction A3 in the first transition section 1231, flows to the smoke outlet 1233 along the direction A4 in the second transition section 1232, and finally is discharged along the smoke outlet 1233.

It can be appreciated that in the process of the fume from the supergravity outlet 1213 to the fume outlet 1233, the flow direction of the fume is changed due to the rotation angle between the first transition section 1231 and the second transition section 1232, so that the residual water vapor in the fume can be inhibited, the water vapor in the fume can be condensed into a liquid state in the fume exhaust adaptor 123, thereby being beneficial to recovering the water vapor in the fume, and the discharged fume can be prevented from being directly contacted by a user, and the trouble caused by the contact of the fume by the user can be reduced.

Additionally, in some embodiments, the smoke evacuation adapter 123 includes a water return structure (not shown). The return water structure can be arranged at the corner between the first transition section 1231 and the second transition section 1232, so that water vapor in the oil smoke can be condensed at the return water structure, and the return water structure can discharge condensed water formed by condensing the water vapor into the liquid storage tank 1215, so that the condensed water can be used for purifying oil drops instead of directly discharging the condensed water, and the full utilization of the condensed water is facilitated.

Referring to fig. 1 and 7, a cooking apparatus 300 according to an embodiment of the present utility model includes a cooking device 200 and the smoke evacuation system 100 according to any one of the above embodiments. The smoke evacuation system 100 is used to suck the smoke generated by the cooking device 200.

Above-mentioned cooking equipment 300 can collect the charged oil drop granule in the oil smoke through static structure 141, can reduce the oil drop content in the oil smoke, through forming adsorption area, when the oil smoke passes through adsorption area along first direction, the oil drop in the oil smoke can be adsorbed by the liquid drop and increase self weight, and then makes the gravity of oil drop be greater than self buoyancy and fall along the second direction to separate the oil drop from the oil smoke, realize the oil smoke purifying effect to the oil smoke.

Specifically, in fig. 7, two cooking apparatuses 200 are included in the cooking apparatus 300. One of the cooking devices 200 may include an automatic wok and the other cooking device 200 may include a kitchen range. The fume extraction system 100 includes a fume extraction assembly 110 and a purification assembly 120. The smoke evacuation system 100 may absorb the smoke generated by a corresponding one of the cooking devices 200 through the smoke evacuation assembly 110 and guide the absorbed smoke to flow to the purification assembly 120 so that the purification assembly 120 purifies the smoke. In other embodiments, the cooking apparatus 200 in the cooking device 300 may be only one, i.e., the cooking apparatus 200 is an automatic wok or a kitchen range.
