Referring to fig. 1, a nozzle 100 of the present invention includes a connecting plate 10 and an oil receiving plate 20. The connection plate 10 is provided with a plurality of first through holes 11, and the plurality of first through holes 11 are arranged at intervals. One end of the oil receiving plate 20 is connected to the connection plate 10, and the oil receiving plate 20 is disposed obliquely downward from the connection plate 10 to guide the oil droplets 50 to flow to a side far from the connection plate 10.

According to the oil nozzle 100 of the embodiment of the invention, the plurality of first through holes 11 are formed in the connecting plate 10, and the air flow is guided to pass through the plurality of first through holes 11, so that turbulence is reduced, oil drops 50 are prevented from flying out under the action of turbulence, oil smoke attached to the oil nozzle 100 is reduced, in addition, the plurality of first through holes 11 are formed in the connecting plate 10, the area of the connecting plate 10, to which the oil smoke can be attached, is reduced, oil drops 50 condensed on the connecting plate 10 are reduced, and the probability of the oil drops 50 condensed on the connecting plate 10 is reduced.

Specifically, the oil nozzle 100 is used for kitchen appliances, when the fan assembly 500 of the kitchen appliance sucks oil smoke, oil drops 50 formed by oil smoke condensation exist in the fan assembly 500, the oil drops 50 are condensed, gathered and drop downwards under the action of gravity, at this time, the oil nozzle 100 can guide the oil drops 50 flowing out of the fan assembly 500, guide the oil drops 50 to a preset oil drop 50 collecting position, and reduce the drop of the oil drops 50 to a cooking bench, a cooker and other positions.

Referring to fig. 2, in the prior art, the oil nozzle is only provided with a through hole for connecting with the volute of the fan assembly, so that when the fan assembly operates, turbulent flow is generated at the oil nozzle by flowing air, and the probability that oil drops on the oil nozzle fly out of the oil nozzle under the action of the turbulent flow and drop on a cooking bench, a cooker and the like is increased; in addition, the area of the oil nozzle is larger, and the coagulation position of the oil supply drops is larger, so that the oil drops are easier to coagulate on the oil nozzle, and the oil drops are easier to drop.

According to the oil nozzle 100 in the embodiment of the invention, the plurality of first through holes 11 are formed in the connecting plate 10, and the air flow passes through the plurality of first through holes 11, so that the probability of turbulent flow generated by the impact of the air flow on the connecting plate 10 is reduced, the time of the air flow in the vicinity of the connecting plate 10 to wander is also reduced, the probability of oil smoke condensation on the connecting plate 10 is reduced, and in addition, the plurality of first through holes 11 are formed in the connecting plate 10, the area of the connecting plate 10 is reduced, and the area of the connecting plate 10, which can be attached by the oil smoke, is reduced.

The oil nozzle 100 is used for being mounted on the volute 300 of the fan assembly 500, when the oil nozzle 100 is mounted on the volute 300, the connecting plate 10 can extend along the vertical direction, the connecting plate 10 can also have an included angle of 10 °, 20 °, 30 °, 40 ° or the like with the vertical direction, the connecting plate 10 can also partially extend along the vertical direction, the included angle of 10 °, 20 °, 30 °, 40 ° or the like with the vertical direction, and the extending direction of the connecting plate 10 can guide the oil drops 50 moving downwards under the action of gravity onto the oil receiving plate 20, which is not particularly limited herein.

The number of the first through holes 11 is very large and may be 2, 3, 4, 5, 10, 20, etc., and the number of the first through holes 11 is adjusted according to factors such as the size of the connection plate 10, the size of the first through holes 11, the rigidity of the material of the connection plate 10, etc., and is not particularly limited herein.

The shape of the first through hole 11 is many, and it may be circular, square, trapezoid, oval, etc., and the shape of the first through hole 11 may be adjusted according to whether it is convenient to produce, use effect, etc., and is not particularly limited herein. Specifically, referring to fig. 1, in one embodiment, the first through hole 11 is formed with a rectangular shape and a semicircular shape. Referring to fig. 6, in a certain embodiment, the first through hole 11 is triangular in shape.

It should be noted that the shapes of the plurality of first through holes 11 may be all the same, the shapes of the plurality of first through holes 11 may be all different, and the shapes of the plurality of first through holes 11 may be partially the same or partially different. The sizes of the plurality of first through holes 11 may all be the same. In this way, it is convenient to produce a plurality of first through holes 11. The sizes of the plurality of first through holes 11 may all be different. In this way, the larger first through holes 11 may be disposed at the position with better turbulence reducing effect, and the smaller first through holes 11 may be disposed at the position with worse turbulence reducing effect, so as to balance the turbulence reducing and the strength of the connecting plate 10. The sizes of the plurality of first through holes 11 may be partially the same or partially different, and will not be described in detail herein.

The plurality of first through holes 11 may be uniformly distributed on the connection plate 10, and the plurality of first through holes 11 may be randomly distributed on the connection plate 10, which is not particularly limited herein.

The material of the connection plate 10 may be metal, plastic, etc., and is not particularly limited herein. The material of the oil receiving plate 20 may be metal, material, etc., and is not particularly limited herein.

There are many ways to produce the connection plate 10 and the oil receiving plate 20. Specifically, the connection plate 10 may be separately disposed with the oil receiving plate 20, and fixedly connected by welding, bonding, or the like. Thus, the connecting plate 10 and the oil receiving plate 20 can be conveniently produced according to the needs, and the shapes of the connecting plate 10 and the oil receiving plate 20 can be independently adjusted. The connection plate 10 may also be integrally formed with the oil receiving plate 20, for example, the connection plate 10 is injection molded with the oil receiving plate 20; for another example, the connecting plate 10 and the oil receiving plate 20 are formed by bending a plate. Thus, no gap exists between the connecting plate 10 and the oil receiving plate 20, so that the oil drops 50 are prevented from dripping through the gap, and the oil drops 50 are prevented from being stored in the gap to corrode the connecting plate 10 or the oil receiving plate 20.

The oil receiving plate 20 is used for guiding the oil droplets 50 flowing down from the connection plate 10 to guide the oil droplets 50 to a position where the oil droplets 50 are preset to be collected, for example, a side of the oil receiving plate 20 away from the connection plate 10 is located directly above an oil cup of a kitchen appliance. In the case that the kitchen appliance is provided with an oil cup, the length and the inclination angle of the oil receiving plate 20 can be adjusted according to the relative positional relationship between the connecting plate 10 and the oil cup, and detailed description thereof will be omitted.

It should be noted that, the oil droplets 50 can be guided by both sides of the oil receiving plate 20.

There are many processes for manufacturing the nozzle tip 100. Specifically, in one embodiment, the nozzle tip 100 is manufactured by metal stamping, such as sheet metal, sheet metal spraying, and the like. In one embodiment, the nozzle tip 100 is cast, such as by zinc alloy casting, aluminum alloy casting, or the like. In one embodiment, the nipple 100 is manufactured by injection molding. This is the case. The oil nozzle 100 has a fireproof and oil-proof effect.

In some embodiments, referring to fig. 1 and 3, the plurality of first through holes 11 are arranged along a straight line.

In this way, it is convenient to provide a plurality of first through holes 11.

Specifically, the plurality of first through holes 11 may be arranged along the width direction of the connection plate 10, and the plurality of first through holes 11 may be arranged at an angle to the direction along the length direction of the connection plate 10, which is not particularly limited herein.

Further, referring to fig. 1 and 3, a plurality of first through holes 11 are arranged along the length direction of the connection plate 10.

Thus, the first through holes 11 are not only convenient to arrange, but also the total area of the plurality of first through holes 11 can be conveniently enlarged.

Specifically, compared with the case where the difference between the length and the width of the first through hole 11 is large, that is, the first through hole 11 is long and thin, the difference between the length and the width of the first through hole 11 is less convenient for production. Thus, the plurality of first through holes 11 are arranged along the length direction of the connection plate 10, and the plurality of first through holes 11 with small length and width differences are conveniently arranged.

In some embodiments, referring to fig. 3, the interval n between two adjacent first through holes 11 is twice or more the thickness of the connecting plate 10.

In this way, the plurality of first through holes 11 are conveniently arranged, and the problem of insufficient rigidity of the connecting plate 10 caused by too small gaps among the plurality of first through holes 11 is also avoided.

Specifically, the interval between the adjacent two first through holes 11 may be twice, three times, four times, etc. the thickness of the connection plate 10, without being particularly limited herein.

It should be noted that, in some embodiments, the interval n between the two first through holes 11 is less than or equal to four times the thickness of the connection plate 10. In this way, it is possible to avoid excessive oil droplets 50 flowing down on the interval between the two first through holes 11, reducing the probability of the oil droplets 50 dripping from the connection plate 10. Specifically, the smaller oil drop 50 is not easy to drop, the larger oil drop 50 is easy to drop under the action of gravity, the interval between the two first through holes 11 is reduced, the formation of the larger oil drop 50 between the two first through holes 11 is avoided, in addition, when the larger oil drop 50 passes through the space between the two first through holes 11, the width and the interval of the oil drop 50 are equal, namely the width of the oil drop 50 is reduced, the volume of the oil drop 50 is unchanged, so that the length of the oil drop 50 is increased, the contact area between the oil drop 50 and the connecting plate 10 is increased, the friction force between the connecting plate 10 and the oil drop 50 is increased, and the dropping probability of the oil drop 50 is reduced.

In some embodiments, referring to fig. 3, the connection plate 10 includes a fixing portion 101 and a connecting portion 102, the connecting portion 102 connects one end of the oil receiving plate 20 and one end of the fixing portion 101, a plurality of first through holes 11 are disposed in the connecting portion 102, and a distance between the first through holes 11 and an edge of the connecting portion 102 is twice a thickness of the connection plate 10.

In this way, the shortage of strength of the connection plate 10 due to the excessively large number of the first through holes 11 is avoided, and the poor effect of eliminating turbulence due to the excessively small number of the first through holes 11 is also avoided.

Specifically, the fixing portion 101 may be used to connect with the scroll case 300 of the fan assembly 500 to fix the nozzle 100. The connection portion 102 may serve to guide the oil droplets 50 flowing down by the fixing portion 101 to the oil receiving plate 20.

The fixing portion 101 and the connecting portion 102 may be separately provided, and thus, the fixing portion 101 and the connecting portion 102 may be fixedly connected by welding, bonding, or the like. The fixing portion 101 and the connecting portion 102 may be integrally formed, so that the fixing portion 101 and the connecting portion 102 are convenient to produce.

Further, referring to fig. 3, 4 and 6, the fixing portion 101 is provided with a fixing hole 1011.

In this manner, the nipple 100 may be connected to the scroll 300 of the fan assembly 500 through the fixing portion 101.

Specifically, there are many ways in which the nipple 100 can be connected to the scroll 300. In a certain embodiment, the scroll case 300 may be provided with a hook, and the fixing hole 1011 is penetrated through the hook in a state that the nozzle tip 100 is mounted to the scroll case 300. In a certain embodiment, the scroll case 300 may be provided with screw holes, and screws are fitted through the fixing holes 1011 to the screw holes to achieve connection of the nozzle tip 100 and the scroll case 300. In one embodiment, the nipple 100 and the scroll 300 are welded through the fixing hole 1011.

In some embodiments, referring to fig. 1, 4 and 5, the connecting plate 10 is further provided with a second through hole 12, and the second through hole 12 is disposed obliquely.

In this way, when the oil drops 50 drop downwards from the connecting plate 10 under the action of gravity, the oil drops 50 can enter the inner side of the oil receiving plate 20 through the second through holes 12, so that the problem that the oil drops 50 drop from the oil receiving plate 20 is avoided, in addition, the second through holes 12 can guide air flow to pass through the second through holes 12, turbulence is reduced, the oil drops 50 are prevented from flying out under the action of turbulence, the area of the connecting plate 10, which can be attached by oil smoke, can be reduced by the second through holes 12, and the oil drops 50 condensed on the connecting plate 10 are reduced.

The included angle between the second through hole 12 and the vertical direction may be 5 °, 10 °, 15 °, 20 °, etc., which is not particularly limited herein. It should be noted that the plurality of first through holes 11 may be disposed obliquely. In this way, the oil droplets 50 can flow into the inner side of the oil receiving plate 20 through the plurality of first through holes 11, and the oil droplets 50 are prevented from dripping from the outer side of the oil receiving plate 20.

In some embodiments, referring to fig. 3, the distance m between the second through hole 12 and the edge of the connection plate is four times the thickness of the connection plate 10. In this way, it is difficult to manufacture the connection plate 10 provided with the second through holes 12 neither because the second through holes 12 are too large nor because the second through holes 12 are too small, so that the oil droplets 50 are difficult to fall from the second through holes 12 onto the oil receiving plate 20.

In some embodiments, referring to fig. 5, the angle α between the oil receiving plate 20 and the horizontal direction is greater than or equal to 8 °.

In this way, it is ensured that the oil droplets 50 can flow under the guidance of the oil receiving plate 20, and the phenomenon that the oil droplets 50 adhere to the oil receiving plate 20 and cannot flow due to insufficient inclination angle is avoided.

Specifically, the included angle α between the oil receiving plate 20 and the horizontal direction is greater than or equal to 8 ° when the nipple 100 is in the mounted state. The larger the inclination angle of the oil receiving plate 20 is, the more smoothly the oil droplets 50 slide on the oil receiving plate 20. It should be noted that, in some embodiments, the angle α between the oil receiving plate 20 and the horizontal direction is less than or equal to 30 °. In this way, the volume occupied by the spout 100 is reduced, and the dripping of the oil droplets 50 due to too fast a flow is avoided.

In some embodiments, referring to fig. 1, 4 and 5, the oil nozzle 100 further includes two oil baffles 30, and the two oil baffles 30 are respectively mounted on two sides of the oil receiving plate 20.

Thus, the oil baffle 30 blocks the oil droplets 50 from flowing out of the oil receiving plate 20.

Specifically, when the oil droplets 50 flow on the oil receiving plate 20, the oil droplets 50 may flow out from two sides of the oil receiving plate 20, thereby affecting the user experience, and by providing two oil baffles 30 on two sides of the oil receiving plate 20, even if the oil droplets 50 move to two sides of the oil receiving plate 20, the oil droplets will remain on the oil baffles 30 under the action of the oil baffles 30 until being guided to the side of the oil baffles 30 away from the connecting plate 10.

It should be noted that, in some embodiments, the side of the oil receiving plate 20 connected to the connecting plate 10 is not provided with the oil baffle 30. In this way, in general, most of the oil droplets 50 of the oil receiving plate 20 flow down from the connecting plate 10, so that the side provided with the connecting plate 10 can be regarded as an oil inlet, and if the oil baffle 30 is arranged at the oil inlet, the oil inlet is blocked, so that the problem that the oil receiving plate 20 cannot receive the oil droplets 50 flowing down from the connecting plate 10 under the blocking of the oil baffle 30 is avoided. In some embodiments, the side of the oil deflector 30 remote from the connection plate 10 is not provided with an oil deflector 30. In this way, the oil baffle 30 does not block the oil droplets 50 from flowing out of the side, and the situation that the oil droplets 50 cannot flow out of the side of the oil baffle 30 away from the connecting plate 10 under the obstruction of the oil baffle 30 is avoided.

Further, referring to fig. 1 and 6, the oil nozzle 100 further includes a pin 40, one end of the oil baffle 30 is connected to the oil receiving plate 20, and the other end of the oil baffle 30 is connected to the pin 40.

In this manner, the nozzle tip 100 may be mated with the volute 300 of the fan assembly 500 through the pin 40, thereby enabling installation of the nozzle tip 100 with the volute 300.

Referring to fig. 7 to 10, a fan assembly 500 is provided according to an embodiment of the present invention, including the nozzle tip 100, the fan 200, and the volute 300 as described in the above embodiments. The volute 300 is provided with a containing cavity 310, an air inlet 320 and an air outlet, wherein the air inlet 320 and the air outlet are communicated with the containing cavity 310, the fan 200 is installed in the containing cavity 310, and the oil nozzle 100 is installed at the bottom of the volute 300 and is positioned at the lower end of the air inlet 320.

In the fan assembly 500 according to the embodiment of the invention, the plurality of first through holes 11 are formed in the connecting plate 10, and the air flow is guided to pass through the plurality of first through holes 11, so that turbulence is reduced, oil drops 50 are prevented from flying out under the action of turbulence, and oil smoke attached to the oil nozzle 100 is reduced.

Specifically, the fan 200 includes, but is not limited to, a motor and an impeller assembly, where the impeller assembly may include a plurality of blades, and the impeller assembly is driven by the motor to rotate, so that a pressure difference is generated near the fan 200, and an air flow enters the fan 200 from the air inlet 320 and is discharged from the air outlet under the action of the pressure difference.

During the process of sucking the oil smoke by the blower assembly 500, the air flow with the oil smoke particles continuously enters the accommodating chamber 310 of the scroll case 300 and contacts the chamber wall of the accommodating chamber 310 and the blower 200, so that the oil droplets 50 are condensed on the chamber wall of the accommodating chamber 310 and the blower 200, and the oil droplets 50 condensed inside the accommodating chamber 310 may flow out from the air inlet 320, and thus the oil nozzle 100 is mounted at the lower end of the air inlet 320 to guide the oil droplets 50 flowing out from the air inlet 320. In addition, in order to facilitate the outflow of the oil droplets 50 in the accommodating chamber 310, an oil drain hole may be further provided at the bottom of the scroll case 300, and the oil drain hole may be located above the oil receiving plate 20 of the oil nozzle 100, so that the oil nozzle 100 receives and guides the oil droplets 50 flowing out from the oil drain hole.

In some embodiments, referring to fig. 10, the nozzle 100 includes a pin 40, and a limit groove 330 is formed at the bottom of the volute 300 to match the pin 40.

In this way, the pin 40 is inserted into the limiting groove 330 to limit the oil nozzle 100, so that the oil nozzle 100 can be mounted at the bottom of the volute 300.

Specifically, referring to fig. 1, the oil nozzle 100 may include a connection plate 10, an oil receiving plate 20 connected to the connection plate 10, and two oil baffles 30 located at two sides of the oil receiving plate 20. One end of the oil baffle 30 is connected to the oil receiving plate 20, and the other end of the oil baffle is connected to the pin 40.

The connecting plate 10 of the oil nozzle 100 may be provided with a fixing hole 1011, the oil nozzle 100 is matched with the volute 300 through the fixing hole 1011 and a screw, and the extending direction of the limiting groove 330 may be consistent with the opening direction of the fixing hole 1011. So, the installation direction of the pin 40 and the limit groove 330 is consistent with the opening direction of the fixing hole 1011, after the pin 40 is inserted into the limit groove 330, the screw penetrates through the limit hole and is fixed on the volute 300, so that the screw not only can limit the oil nozzle 100, but also can prevent the pin 40 from separating from the limit groove 330, so that the oil nozzle 100 is more firmly connected with the volute 300, in addition, when the oil nozzle 100 needs to be detached from the volute 300, the screw is detached, and the pin 40 of the oil nozzle 100 can be conveniently separated from the limit groove 330, thereby realizing the detachable connection of the oil nozzle 100 and the volute 300.

Embodiments of the present invention provide a kitchen appliance including a blower assembly 500 as described in the above embodiments.

According to the kitchen appliance, the plurality of first through holes 11 are formed in the connecting plate 10, and air flow is guided to pass through the plurality of first through holes 11, so that turbulence is reduced, oil drops 50 are prevented from flying out under the action of turbulence, oil smoke attached to the oil nozzle 100 is reduced, in addition, the plurality of first through holes 11 are formed in the connecting plate 10, the area of the connecting plate 10, which can be attached by the oil smoke, is reduced, oil drops 50 condensed on the connecting plate 10 are reduced, and the probability of the oil drops 50 condensed on the connecting plate 10 is reduced.
