The Sidewall Height of the separate inner walls side used in the examples is lower than close to oil scupper close to inner walls side Sidewall Height, can not only play the role of degreasing, but also can play and excessively overflow；Traditional blowdown Mode or by the way of being expelled directly out or by the way of regularly replacing cleaning solution does not need setting oil scupper；But Above scheme otherwise with after long-time service adsorption effect decline or a large amount of detergent can be expended, however aforesaid way is real It applies but very easy, which save the expense of structure and material, can be used to make up detergent in a long time clear Clean cost of use, and without the sealing problem after the welding and welding in consideration small space when design, but exist to suction Attached ineffective phenomenon, designer, will not be using increasing cost and design difficulty under the premise of meeting environmental protection standard Mode is further reduced the problem of being likely to occur.

In addition, greasy dirt inherently swims in the surface of circulation solution, oil directly can be discharged in side wall setting outage Dirt, and the bottom in absorption storehouse is arranged in drainpipe, itself need not this mode for increasing cost of setting oil scupper to carry out Mixed solution is recycled；However it has been found that will appear greasy dirt amount shakiness during cooking during actual experiment Fixed phenomenon, greasy dirt amount is fluctuated, if greasy dirt cannot be discharged in time, will appear drainpipe lower part and sucks again The phenomenon that greasy dirt is recycled, but kitchen ventilator will not be damaged in a short time, but after being used for a long time, so that kitchen ventilator is originally Be not in occur greasy dirt on greasy dirt component, then can seriously affect the adsorption effect of smoke machine, but for those skilled in the art For, influence of this greasy dirt to smoke extractor be it is negligible, will not influence the normal use of smoke extractor, but will affect its length Phase using effect.

It channel steel and is directly used in addition, the oil extraction slot structure used can be purchased in market, this mode naturally can will be oily Dirt is discharged, but it can still bring a new technical problem, how to be sealed, how to guarantee in small space The stability of greasy dirt discharge, actually uses by inventor and finds, be arranged and be not provided with not having obvious effects on difference, for this For the technical staff of field, due to not having obvious effects on, and increase cost, therefore those skilled in the art will not to herein into Row improves, and does not have motivation to being improved again herein naturally；And inventor is using channel steel by pondering deeply and inferring On the basis of, one side wall is increased so that greasy dirt from channel steel height compared in low sidewall along enter oil scupper in after, due to higher oil extraction The blocking of slot is so that even high speed will not generate sling liquid and enter in absorbing cabin, thus really into the greasy dirt in oil scupper The effect of oil extraction dirt is protected；In addition, circulation solution can also be isolated in higher side wall, so that drainpipe lower absorbent Greasy dirt is not present in circulation solution upper surface as far as possible, it is ensured that the effect of circulation, when circulating water chennel water level is high, although absorbing cabin Lower part water level is high, but due to the blocking of dirt discharge groove, prevent greasy dirt is from interfering drainpipe；But also oil scupper can Quickly discharge or temporary greasy dirt quickly reduce the greasy dirt content in circulating water chennel, so that mixed solution will not be very dirty, it is ensured that Adsorption effect when circulation solution uses；In general for oil scupper, main function is exactly and the knot in order to be discharged greasy dirt Structure can not only exclude greasy dirt, but also can keep in greasy dirt, and mixed solution is avoided to splash, while can also will be more Remaining solution discharge, can reduce the content of greasy dirt in mixed solution, it is ensured that clear in present apparatus operational process to greatest extent Clean effect, this is that those skilled in the art are not readily conceivable that.

Example IV

As Figure 7-8, the difference with embodiment three is: the quantity of the maze board 3 is three pieces, before first piece of maze board End tilts down and first piece of maze board rear end is connected with 1 rear wall of shell, is arranged in second piece below first piece of maze board Maze board rear end is connected with the water curtain plate 10, and setting is below second piece of maze board and mutual with first piece of maze board The third block maze board being arranged in parallel on 1 rear wall of shell.

The trough plate 301 that the maze board 3 is stacked by muti-piece forms.

The two sidewalls of the trough plate and the angle of bottom panel are 40 °.

The mode that three pieces of maze boards used in the examples are staggered, enables to oil smoke on the channel of exclusion, Many places vortex is formed, oil smoke residence time is extended；In addition, the flute profile board group that the maze board used is stacked by muti-piece At enabling soot gas during rising, not only due to vortex can be formed at maze board, and fan can also be passed through Trough plate is staggered in the plate of palace, forms multibarrier, so that droplet is repeatedly collided, further improves oil smoke suction The effect of receipts can be reduced further to extraneous pollution.

In addition, the fume-exhausting of conventional range hood all has the upper limit, it will appear two problems after reaching, first is It cannot continue to keep very high adsorption effect, second cannot be improved again in medium altitude, and in the embodiment, when this dress It sets improving 8% adsorption effect by labyrinth board stacking and by way of using special trough plate, if being only arranged one piece The mode of entire trough plate in practical effect, only improves only 1% adsorption effect, and if the layer of trough plate setting When number is more than two layers, it is found only through overtesting can increase 3% adsorption effect, it can be seen that, only use labyrinth in the implementation When plate mode and the trough plate two sidewalls used and bottom panel angle is 40 °, additional 8% addition could be obtained, to obtain 98% adsorption effect.

In addition, applicant uses the trough plate mode being stacked in many experiments, industry is generally acknowledged that this set In order to increase the oil mixing with water gas of rising and the contact area of trough plate, natural contact area is the bigger the better mode, but applies People has found in the course of the research, and oil smoke is due to itself containing certain temperature, so that it is after cascade, most oil smoke Form mixture with detergent or water, form mixed solution and enter in circulating water chennel, and some can not be melted or The soot gas escaped out forms the small water mist of numerous greasy dirt by atomizing mouth, rises to maze board region, carried out by maze board Stop and to be recombinated between greasy dirt particle, condenses into larger mixed solution water droplet, and flow downward out along trough plate, collect Into circulating water chennel, however since soot gas is in uphill process, as the increase of collision frequency and new entrance are wherein oily The collision and enrichment of flue gas body so that condensed originally or and the water droplet of enrichment bring new energy, and then keep its heavy New gasification enters in oil smoke, so that the effect to degrease does not rise anti-drop；Applicant by attempting discovery many times, only In two pieces of the lower part trough plate that the present invention is arranged, three pieces of trough plates are arranged in top, and work as trough plate two sidewalls and bottom panel When angle is 40 °, adsorption effect can be improved to greatest extent, adsorption effect is enabled to increase by 8% on the original basis Adsorption effect.

When two pieces of trough plates are arranged in turn, are found by applicant's practical study, only increase 2% suction Attached effect, same contact surface and quantity, if setting position and mode difference if also will appear effect difference the phenomenon that, this It is that institute is unexpected in actual use by user of the invention.

For the embodiment optimum efficiency further elucidated above, applicant's changing section data obtain following technical effect:

Number	The maze board number of plies and plate number	Trough plate cross sectional shape	The angle of trough plate two sidewalls and bottom surface	Increase the adsorption effect (%) of oil smoke
					1	1 layer and one piece	"-" type	90°	1
2	2 layers and three pieces	It is just Chinese character pin-shaped	90°	1.5
					3	2 layers and five pieces	It is just Chinese character pin-shaped	90°	1.6
4	3 layers and six pieces	It is just Chinese character pin-shaped	90°	1.8
					5	2 layers and three pieces	It is Chinese character pin-shaped	90°	3.5
6	3 layers and six pieces	It is Chinese character pin-shaped	90°	3.8
					7	4 layers and ten pieces	It is Chinese character pin-shaped	90°	4
8	2 layers and three pieces	It is Chinese character pin-shaped	60°	4.2
					9	3 layers and six pieces	It is Chinese character pin-shaped	60°	3.1
10	4 layers and ten pieces	It is Chinese character pin-shaped	60°	2.3
					11	2 layers and three pieces	It is Chinese character pin-shaped	50°	3.6
12	2 layers and three pieces	It is Chinese character pin-shaped	40°	8
					13	2 layers and three pieces	It is Chinese character pin-shaped	30°	2.7
14	2 layers and three pieces	It is Chinese character pin-shaped	43°	4.4
					15	2 layers and three pieces	It is Chinese character pin-shaped	41°	4.4
16	2 layers and three pieces	It is Chinese character pin-shaped	40°	8
					17	2 layers and three pieces	It is Chinese character pin-shaped	39°	3.8
18	2 layers and three pieces	It is Chinese character pin-shaped	36°	3.6
					19	2 layers and three pieces	It is Chinese character pin-shaped	35°	3.9

As can be seen from the above table, trough plate just Chinese character pin-shaped it can be seen from 1-4 setting, with the maze board number of plies and plate number Increase, the contribution that effect is made is slowly increased, but effect is unobvious；Then inventor readjusts thinking and uses The trough plate layout type of product word, such as 5-7, although with the increase of the maze board number of plies and plate number effect can also be made it is slow Slow increase, but effect is still not obvious enough；But relative to just Chinese character pin-shaped structure, effect has apparent increasing trend, in Be that applicant thinks to improve trough plate two sidewalls when layout has limitation so that two sidewalls and trough plate bottom plate it Between at 60 ° of angles, such as 8-10, by the way of the different numbers of plies and block number, discovery not as the number of plies and plate number increase so that Effect exponentially rises, but same contrast effect is best when plate number and the number of plies are two layers and three pieces；Then applicant from Continue to set about the angle of trough plate two sidewalls, change angle, finds when angle is adjusted to 40 °, effect most preferably 8%, Inventor think its may with the reduction of angle increased effect, in being to continue with reduction angle, but find to treat as 30 ° of timeliness Fruit is only 2.7%, is fallen in cliff of displacement formula, and then for applicant's emphasis to being tested within the scope of 40 °, discovery is either greater than 40 ° Also it is less than the range of 40 ° of angles, effect is unobvious and the order of magnitude that differs greatly with 40 ° of angles, in order to continue to verify Technical effect brought by 40 ° of angles is not that those skilled in the art obtain by rationally inferring, has been carried out following subsequent Comparative test.

Applicant further adjusts the angle of the two sidewalls of trough plate and bottom plate, and employing mode is as follows with effect Shown in table:

20	2 layers and three pieces	It is Chinese character pin-shaped	40.3°	4.5
					21	2 layers and three pieces	It is Chinese character pin-shaped	40.2°	4.3
22	2 layers and three pieces	It is Chinese character pin-shaped	40.1°	4.6

Even if it was found that reduce angle infinitely close to 40 degree angles when, there is no significantly surge phenomenon yet；Then applicant is from 40 ° The effect for carrying out test acquisition downwards is as shown in the table:

23	2 layers and three pieces	It is Chinese character pin-shaped	39.9°	3.85
					24	2 layers and three pieces	It is Chinese character pin-shaped	39.8°	3.9
25	2 layers and three pieces	It is Chinese character pin-shaped	39.7°	4.2

As can be seen from the above table, even if when below 40 ° of angles unlimited close mode upwards, also swash without obvious appearance effect The phenomenon that increasing, it can be seen that the optimum implementation in the present embodiment is not to get sth into one's head and obtain, and is that inventor is testing With the unexpected technical effect to stumble in summary.

The course of work of the invention: corresponding exhausting air-valve is opened as needed, and opens exhaust fan, in exhaust fan Under the action of gravitation, so that air inlet of the soot gas from upper part of the housing close to water curtain plate enters in shell, and water curtain plate was listened It enters at the atomizing mouth of lower part of the housing, by entering maze board area thereafter, oil residues is captured, so that being discharged into air upwards In gas, contain minimal amount of oil smoke；In addition, the modes such as dish washing liquid or washing powder can be added in oil scupper or vibration means for main pipe for supplying water road Improve the effect of oil suction.

The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications It should be regarded as protection scope of the present invention.
