In order that the present invention may be better understood in those skilled in the art, technical solution of the present invention is further illustrated with reference to the accompanying drawings and examples.
As Figure 1-4, a kind of jetting type degreasing unit, side is used primarily in absorb on smoke exhaust ventilator, it includes the blower fan 2 being sequentially connected, steam generating means 3 and send vapour nozzle 4, wherein blower fan 2 and steam generating means 3 are all disposed within the lower section of cooktop 5, vapour nozzle 4 is sent to be arranged on the anterior top of cooktop 5 of the kitchen range top, and connect steam generating means 3 by the vertical steam delivery tube road 7 positioned at the top of cooktop 5 and positioned at the horizontal steam delivery tube road 6 of the lower section of cooktop 5, send flat ligule spout 41 of the vapour nozzle 4 provided with injection steam, the front end of spout 41 is inner circle arc, the two side 43 of spout 41 is flared outwardly to create certain angle, steam is ejected with certain radiation angle, spout 41 sprays vapour direction and absorbs mouth 1 towards side, the collocation work of mouth 1 is absorbed with side.
Shown in Fig. 4, the angle that the two side 43 of spout 41 is formedIt is preferably limited in the range of 90 ° ~ 120 °, such setting can enable the large range of pot face 8 covered when cooking of steam for sending vapour nozzle 4 to spray（Dotted line circular arc shown in Fig. 4）, the edge for substantially reducing oil smoke is escaped.It is worth noting that, the angle that two side 43 is formed is too small, can cause steam can not large range of covering pot face 8, it is excessive if, the manufacture difficulty of spout 41 is bigger than normal, and two side spray vapour effects are not fine.Water vapor injection during different angles is calculated below by Fig. 2 can cover the scope in pot face 8.
By taking family expenses frying pan as an example, frying pan diameter D on the market（Radius is r）Typically in 28-34cm, 34cm is taken here, if the angle that two side 43 is formed is, it is simplified operation, as shown in fig. 5, it is assumed that spout 41 is a particle A, it is with radiation angleSize goes out water vapor injection, wherein AB extended lines and the scope that the angle of AC extended lines formation is water vapor injection, then the scope S that water vapor injection is covered on pot face 8（Shaded area shown in figure）For：
Scope S accounts for the ratio of pot surface areaFor：
When=90 °, i.e.,When,；
When=120 °, i.e.,When,。
As can be seen that when the size of spout 41 is not-time, its steam sprayed can at least cover the area of the top of pot face 8 81.8%, it is seen that such design has been able to make most of oil smoke on pot face to be limited by wind screen, can be with oil smoke assimilation effect.
The actually front end of spout 41 is provided with the inner circle arc for coordinating the kitchen range top, as shown in figure 4, therefore the spout 41 has certain arc length s, in order to ensure that pot face 8 does not influence to send the work of vapour nozzle 4, the edge of pot face 8 should keep certain radial distance, d with the spout 41（Here we take 5cm）, therefore in Fig. 4 spout 41 the equivalent particle A particle As more equivalent than Fig. 5 spout 41 further from pot face edge, can simply infer in water vapor injection radiation angleIn the case of identical, its area ratio for covering pot face 8 can be improved further, and following result is obtained by calculating us：
As shown in figure 4, if it is desired that send vapour nozzle 4 spray steam all covering pots 8, when=90 °, D=34cm, during d=5cm, the inner circle arc length s of spout front end will at least have 4.3cm；When=120 °, D=34cm, during d=5cm, arc length s random lengths can meet requirement, therefore the angle formed in the two side 43 of spout 4190 ° of satisfaction≤In the case of≤120 °, as long as the inner circle arc length of the front end of spout 41 ensures at least 4.3cm length, so that it may so that the steam sprayed covers whole pot face 8.
As shown in Figure 6 and Figure 7, preferred embodiment can be provided with level and the Falling Wedge partition 42 extended to spout internal at spout 41, the partition 42 can be sprayed the steam for entering vertical steam delivery tube road 7 from spout 41 with two different vapour directions of sending, to mitigate weight, the inside of partition 42 can be set to cavity.Under the effect of partition 42, the steam of ejection forms twice wind screen on pot face 8, to oil smoke formation multilayer limitation, so that it is guaranteed that the oil smoke produced is absorbed, the oil and the relatively low organic matter of boiling point of volatilization simultaneously can also be with steam by multiple condensation, ensure oil smoke enter flue after can quickly with vapor deposition under, so as to mitigate the work load of oil-filtering apparatus in flue.
Embodiment more preferably be further send be provided with vapour nozzle 4 can opposed vertical steam delivery tube road 7 swing up and down the device of regulation, the neck of vapour nozzle 4 is such as sent to be fixed with the vertical top sidewall both sides of steam delivery tube road 7 by pin, so operator the injection direction of steam can be adjusted according to the size of oil smoke concentration when cooking, certainly in the specific implementation, vapour nozzle 4 is sent to swing up and down adjustable scope it should be ensured that the direction that spout 41 sprays steam absorbs mouth 1 without departing from side.When oil smoke is less, the water vapor injection elevation angle is improved；When oil smoke is more, the water vapor injection elevation angle is reduced so that oil smoke can be quickly sucked away.
Switch is first opened when in use, the work of steam generating means produces steam, under fan action, steam is sprayed from sending the spout of vapour nozzle, the steam of ejection forms wind screen on the pot face when cooking, the oil smoke for cooking generation can be limited in below wind screen, oil smoke can also be drained into side and absorb mouth by steam, so as to improve oil smoke assimilation effect.When the oil and the relatively low organic matter of boiling point that are volatilized in oil smoke touch the steam ejected, it can enter flue quickly with condensation vapor into drop in the presence of side absorption mouth, eventually pass deposition and be flowed into oil collection box.
The present invention not only can carry out space limitation and direction drainage by way of water vapor injection to oil smoke, and oil smoke can be made quickly to be liquefied with steam, convenient deposition is collected, and greatly strengthen the deoiling effect of oil smoke, mitigate oil-filtering apparatus operating pressure simultaneously, improve service life of structure.
The jetting type degreasing unit that the present invention is provided is described in detail above.The explanation of specific embodiment is only intended to help and understands the method for the present invention and its core concept.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, some improvement and modification can also be carried out to the present invention, these are improved and modification is also fallen into the protection domain of the claims in the present invention.
