[0048] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0049] Embodiment 1:

[0050] The present embodiment provides an air inlet net and a range hood, which are intended to at least to some extent solve the technical problem that oil droplets formed after condensation of oil fumes sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0051] Figure 1 is a schematic diagram of the structure of an air inlet network in this embodiment, Figure 2 for Figure 1 A front view of Figure 1 as well as Figure 2 The air inlet net of this embodiment is applied to a range hood, and the air inlet net comprises a body 1, and the body 1 is installed on the range hood in a horizontal direction, that is, the length direction of the body 1 of the air inlet net is oriented in a horizontal direction. In addition, the two sides of the body 1 in the thickness direction of this embodiment are respectively the air inlet side and the air outlet side, that is, one side in the thickness direction of the body 1 is the air inlet side, and the other side is the air outlet side. When the range hood is working, the external air including oil smoke and the like passes through the air inlet net from the air inlet side, flows to the air outlet side and enters the range hood.

[0052] Combination Figure 1 as well as Figure 2 The main body 1 of this embodiment includes a first panel 101 and a second panel 102. The first panel 101 and the second panel 102 are bent along the length direction of the main body. The opening formed by the first panel 101 and the second panel 102 faces the air inlet side, that is, when the air inlet net is assembled on the range hood, the air inlet net is overall concavely arranged on the range hood.

[0053] Combination Figure 1 as well as Figure 2 In this embodiment, a plurality of first air inlet holes 103 are provided on the second panel 102. When the fan in the range hood is working, a negative pressure zone is formed at the air inlet net of the range hood, and then the fumes generated by cooking are sucked away through the plurality of first air inlet holes 103.

[0054] Combination Figure 1 as well as Figure 2 In this embodiment, a plurality of oil leakage holes 104 are provided on the first panel 101. When the range hood is working, oil droplets formed by condensation of the oil smoke sucked away by the range hood can flow from the oil leakage groove into the inner side of the guide plate, and then flow into the oil collecting box through the guide plate, thereby improving the phenomenon in the prior art that oil droplets drip onto the user's stove along the air inlet net, thereby improving the user experience.

[0055] Furthermore, combined with Figure 1 as well as Figure 2 In this embodiment, the plurality of oil leakage holes 104 are arranged in at least two rows along the width direction of the body 1, and each row of oil leakage holes 104 is arranged at intervals along the length direction of the body 1, and the oil leakage holes 104 in two adjacent rows are arranged in a staggered manner. In the two adjacent rows of oil leakage holes 104, the projections of the two ends of an oil leakage hole 104 in one row along the length direction of the body 1 on the oil leakage holes 104 in the other row are both located on the two adjacent oil leakage holes 104 in the other row. The oil leakage holes arranged in this way can make the projections of the oil leakage holes 104 in different rows along the width direction of the first panel 101 form an oil leakage groove along the length direction of the body. When the range hood is working, the oil droplets formed by the condensation of the oil smoke sucked away by the range hood can flow from the formed oil leakage groove into the inner side of the guide plate, and flow into the oil receiving box through the guide plate, thereby improving the phenomenon that the oil droplets drip onto the user's stove along the air inlet net in the prior art, and improving the user experience.

[0056] In this embodiment, the shape of the oil leakage holes 104 can be round holes, hexagonal holes, diamond holes, special-shaped holes, etc., preferably waist-shaped holes, and the shapes of the oil leakage holes 104 in each row can be inconsistent or consistent, that is, the shape of the oil leakage holes 104 in the first row can be round holes, the shape of the oil leakage holes 104 in the second row can be hexagonal holes, and the shape of the oil leakage holes 104 in the third row can be diamond holes, etc. Of course, the shapes of the oil leakage holes 104 in each row can also be round holes, hexagonal holes, diamond holes, special-shaped holes, etc., as long as the requirements of the above-mentioned oil leakage holes are met, and this embodiment does not limit this.

[0057] Combination Figure 1 as well as Figure 2 Specifically in this embodiment, two rows of oil leakage holes 104 can be set on the first panel 101, namely a first row of oil leakage holes located at the top and a second row of oil leakage holes located at the bottom (based on the state of the range hood when in use). The shape of the first row of oil leakage holes and the second row of oil leakage holes are both waist-shaped holes, and the length direction of the waist-shaped holes is the length direction of the main body.

[0058] Further, Figure 3 for Figure 1 The enlarged schematic diagram of A in the figure is combined with Figure 3 In this embodiment, the length and width of each oil leakage hole 104 in the first row of oil leakage holes are a1 and c1 respectively, and the length and width of each oil leakage hole 104 in the second row of oil leakage holes are a2 and c2 respectively. The sizes of the oil leakage holes in the two rows can be consistent or inconsistent.

[0059] Furthermore, the parameters of each oil leakage hole in this embodiment are: 3mm≤a1(a2)≤40mm, 1.5mm≤c1(c2)≤20mm, preferably, 7mm≤a1(a2)≤20mm, 2.5mm≤c1(c2)≤12mm. The oil leakage hole with such parameter setting can not only ensure the oil guiding effect, but also make the first panel have sufficient use strength, and prevent the vibration and other problems caused by poor strength when it is installed in the whole range hood.

[0060] Specifically in this embodiment, the shapes of the two rows of oil leakage holes 104 are consistent, that is, the length and width of the two rows of oil leakage holes 104 are equal, and the oil leakage holes 104 in each row are evenly spaced, and the spacing between two adjacent oil leakage holes 104 in each row is consistent.

[0061] Furthermore, combined with Figure 1-Figure 3 In this embodiment, in two adjacent rows of oil leakage holes 104, two oil leakage holes 104 located in the same width direction have overlapping parts. When oil droplets cannot flow into the inner side of the guide plate from the upper oil leakage holes 104, they can be guided into the inner side of the guide plate through the overlapping parts of the two adjacent oil leakage holes 104 below.

[0062] Figure 4 for Figure 2 The enlarged schematic diagram of point B in the figure is combined with Figure 4 In this embodiment, the length of the oil leakage hole 104 along the length direction of the body 1 is a, the length of the overlapping part of the two oil leakage holes 104 in the same width direction is b, and the relationship between a and b is: 1 / 4≤b / a≤3 / 4, preferably, 1 / 3≤b / a≤2 / 3. The air inlet net with the oil leakage hole of this parameter has a good oil guiding effect and can prevent the vibration caused by poor strength when it is installed in the whole range hood.

[0063] Preferably, combined Figure 1 In this embodiment, the first panel 101 and the second panel 102 form a V-shape or an arc shape with the opening facing the air inlet side. That is, the connection between the first panel 101 and the second panel 102 can be directly bent or transitioned through an arc shape, which is not limited in this embodiment.

[0064] Furthermore, combined with Figure 1 , Figure 2 as well as Figure 4 In this embodiment, the multiple first air inlet holes 103 on the second panel 102 can be arranged at intervals along the length direction of the main body 1, and the length of each first air inlet hole 103 along the length direction of the main body 1 is L1, and the hole boundary of two adjacent oil leakage holes 104 along the width direction of the main body 1 is K. The relationship between L1 and K is L1<K, that is, one first air inlet hole 103 can correspond to two oil leakage holes 104 located in the same width direction of the main body 1, and the oil droplets guided by one first air inlet hole 103 are introduced into the inner side of the guide plate through the two oil leakage holes, which can further ensure the oil guiding effect.

[0065] In this embodiment, the shape of the first air inlet hole 103 can be a round hole, a hexagonal hole, a diamond hole, a special-shaped hole, etc., which is not limited in this embodiment.

[0066] Preferably, the shape of the first air inlet hole 103 of this embodiment is preferably a waist-shaped hole. When the first air inlet hole 103 is a waist-shaped hole, the length direction of the first air inlet hole 103 is the height direction of the body. Figure 4 In this embodiment, the dimension of the first air inlet 103 in the length direction is slightly smaller than the dimension of the second panel 102 in the width direction, and the opening area (width dimension) of the first air inlet 103 in the width direction is L1, wherein 3mm≤L1≤30mm, and 7mm≤L1≤15mm is the best. In this way, while ensuring that the range hood has sufficient air intake, the strength of the second panel 102 can also be improved to prevent problems such as vibration caused by poor strength when it is installed in the range hood.

[0067] In addition, this embodiment also provides a range hood. Figure 5is a schematic diagram of the structure of the range hood of this embodiment, Figure 6 for Figure 5 A front view of Figure 7 for Figure 5 Explosion diagram of . Figure 5 , Figure 6 as well as Figure 7 The range hood of this embodiment includes a housing 2, an oil receiving box 3 and the above-mentioned air inlet net, wherein the housing 2 is provided with a guide plate 4, the guide plate 4 is provided with an opening, the air inlet net is assembled at the opening of the guide plate 4, the length direction of the air inlet net (body 1) is the horizontal lateral direction of the range hood, the oil receiving box 3 is arranged at the bottom of the housing 2, and the lower side of the guide plate 4 is arranged in the oil receiving box 3.

[0068] When the range hood is working, the oil droplets formed by condensation of the oil smoke sucked away by the range hood can be directed to the first panel 101 through the second panel 102, and fall into the lower side of the guide plate 4 through the oil leakage hole 104 on the first panel 101, and then flow into the oil collecting box 3 through the guide plate 4, thereby improving the phenomenon in the prior art that the oil droplets drip along the air inlet net onto the user's stove, thereby improving the user experience.

[0069] When the air inlet net is installed on the range hood, the first panel 101 preferably has an inclination, that is, the first panel 101 is tilted in actual use, and the first panel 101 and the second panel 102 are concavely arranged, so that the second panel 102 can receive the oil droplets generated inside the range hood case 2 and guide the received oil droplets so that the oil droplets are diverted to the first panel 101 through the second panel 102, and then collected through the oil leakage holes 104 on the first panel 101 and flow into the oil collecting box 3.

[0070] Embodiment 2:

[0071] The present embodiment provides an air inlet net and a range hood, which are intended to at least to some extent solve the technical problem that oil droplets formed after condensation of oil fumes sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0072] Combination Figure 1 as well as Figure 2The air inlet net provided in this embodiment, in the case of the air inlet net shown in the first embodiment, further includes a third panel 105, the second panel 102 is arranged between the first panel 101 and the third panel 105, the second panel 102 and the third panel 105 are bent along the length direction of the body 1, the opening formed by the second panel 102 and the third panel 105 faces the air inlet side, and a plurality of second air inlet holes 106 are arranged on the third panel 105. The third panel 105 and the second panel 102 of this embodiment have similar functions, both of which can allow the air containing oil smoke to circulate, and both of which can receive the oil droplets generated inside the housing 2 of the range hood, and guide the received oil droplets, so that the oil droplets are guided to the first panel 101 through the third panel 105 and the second panel 102 in turn, and then collected and flowed into the oil receiving box 3 through the oil leakage hole on the first panel 101.

[0073] Preferably, combined Figure 1 as well as Figure 2 In this embodiment, the second air inlet hole 106 on the third panel 105 can be consistent in shape with the first air inlet hole 103, and the second air inlet hole 106 and the first air inlet hole 103 are coaxial along the center line of the body 1. Preferably, the second air inlet hole 106 and the first air inlet hole 103 are both waist-shaped holes. Figure 4 In this embodiment, the length dimension of the second air inlet hole 106 is slightly smaller than the width dimension of the third panel 105, and the opening area (width dimension) of the second air inlet hole 106 in the width direction is L2, preferably, L1=L2. In this way, while ensuring that the range hood has sufficient air intake, the strength of the second panel 102 and the third panel 103 can be improved to prevent problems such as vibration caused by poor strength when they are installed in the range hood.

[0074] Of course, the second air inlet hole 106 may also have a shape different from that of the first air inlet hole 103 , and the second air inlet hole 106 and the first air inlet hole 103 may be staggered, etc., and this embodiment does not limit this.

[0075] Combination Figure 1 as well as Figure 2 In this embodiment, the second panel 102 and the third panel 105 form a V-shape or an arc shape with the opening facing the air inlet side. That is, the second panel 102 and the third panel 105 are concavely arranged so that the second panel 102 and the third panel 105 receive the oil droplets generated inside the housing of the range hood.

[0076] As a preferred solution of the present application, the angle between the second panel 102 and the third panel 105 is an obtuse angle. That is, the angle between the second panel and the third panel is θ, wherein 90°<θ<180°, preferably, 120°≤θ≤160°, and the range hood equipped with the air inlet net of the second panel 102 and the third panel 105 having the angle can improve the oil droplet diversion effect.

[0077] On the other hand, combined Figure 5 , Figure 6 as well as Figure 7 Based on the above air inlet net, the present application further provides a range hood, which includes an air inlet net, a housing 1 provided with a guide plate 4, and an oil receiving box 3 arranged at the bottom of the housing 1. The guide plate 4 is provided with an opening, the air inlet net is assembled at the opening of the guide plate 4, and the lower side of the guide plate 4 is arranged in the oil receiving box 3.

[0078] When the range hood is working, the oil droplets formed by the condensation of the oil smoke sucked away by the range hood can be directed to the first panel 101 through the third panel 105 and the second panel 102, and fall into the lower side of the guide plate 4 through the oil leakage hole 104 on the first panel 101, and then flow into the oil collecting box 3 through the guide plate 4, thereby improving the phenomenon in the prior art that the oil droplets drip along the air inlet net onto the user's stove, thereby improving the user experience.

[0079] Figure 8 for Figure 5 Axial section view of Fig. 9 for Figure 8 The enlarged schematic diagram of C in FIG. Figure 8 and Fig. 9 In this embodiment, a first sinker 401 is provided on the open lower side of the guide plate 4, and a second sinker 107 is provided on the lower side of the first panel 101. The first sinker 401 and the second sinker 107 are butted against each other and fixedly connected by snap-fitting or bolts, that is, the lower side of the first panel 101 is assembled on the open lower side of the guide plate 4.

Figure 8 as well as Fig.10 Similarly, in this embodiment, a third sinker 402 is provided on the open upper side of the guide plate 4, and a fourth sinker 108 is provided on the upper side of the third panel 105. The third sinker 105 and the fourth sinker 108 are butted against each other and fixedly connected by snap-fitting or bolts, that is, the upper side of the third panel 105 is assembled on the open upper side of the guide plate 4, thereby completing the assembly of the air inlet net on the range hood.

[0081] In addition, combined Fig. 9 as well as Fig.10 In this embodiment, the abutting surfaces of the first sinker 401 and the second sinker 107 are both planes, and the abutting surfaces of the third sinker 402 and the fourth sinker 108 are also planes, so as to prevent oil droplets from leaking from the gap between the first sinker 401 and the second sinker 107, and the gap between the third sinker 402 and the fourth sinker 108.

[0082] In the prior art, the air inlet net is mostly divided into an upper part and a lower part, and the air inlet net and its mounting sink form many breaks, which easily produce gaps, causing oil to accumulate in the broken gaps and making them difficult to clean. Based on this, the first panel, the second panel and the third panel of the air inlet net of this embodiment can be integrally formed, which can not only improve the overall strength of the air inlet net, but also avoid the air inlet net itself from producing broken gaps, thereby avoiding oil accumulation in the broken gaps and improving the cleanliness of the range hood.

[0084] Embodiment 3:

[0085] The present embodiment provides a range hood with a shell oil guide plate, which is intended to at least to some extent solve the technical problem that oil droplets formed after condensation of oil fumes sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0087] When the range hood equipped with the above-mentioned shell oil guide plate 5 is in operation, some oil droplets formed after the oil smoke sucked away by the range hood is condensed can be gathered on the shell oil guide plate 5, and guided along the shell oil guide plate 5 to the guide plate 4, and then flow into the oil collecting box 3 through the guide plate 4, thereby improving the phenomenon in the prior art that oil droplets drip along the air inlet net onto the user's stove, thereby improving the user experience.

[0088] Preferably, combined Figure 7 as well as Fig.13 , the two sides of the shell oil guide plate 5 in the length direction of this embodiment conflict with the two horizontal longitudinal sides of the box body 2. The two horizontal longitudinal sides of the box body 2 are the front and rear sides of the box body 2, that is, the two sides of the shell oil guide plate 5 in the length direction conflict with the front and rear sides of the box body 2, which can not only improve the installation strength of the shell oil guide plate 5 inside the box body 2, and prevent it from being installed in the whole range hood due to the vibration caused by the difference in strength. In addition, the oil droplets guided by the shell oil guide plate 5 can flow along the front side of the box body 2 to the guide plate 4, and then flow into the oil receiving box 3 through the guide plate 4, and the oil droplets guided by the shell oil guide plate 5 can directly flow along the rear side of the box body 2 directly into the oil receiving box 3, thereby increasing the oil guide area and improving the oil guide effect, so as to further improve the phenomenon that the oil droplets drip onto the user's stove along the air inlet net in the prior art, and improve the user experience.

[0089] In addition, combined Fig.11 as well as Fig.12 In this embodiment, the shell oil guide plate 5 may be provided with a plurality of third air inlet holes 501. Air containing oil smoke may flow into the shell of the range hood through the plurality of third air inlet holes 503.

[0090] Furthermore, the area of ​​the plurality of third air inlet holes 503 of the present embodiment accounts for 30% to 60% of the side area of ​​the shell oil guide plate 5, so as to reduce the air intake wind resistance and ensure the air intake efficiency.

[0091] Combination Fig.11 as well as Fig.12 In this embodiment, a plurality of third air inlet holes 501 may be arranged at equal intervals on the shell oil guide plate 5, and each third air inlet hole 501 may be a waist-shaped hole, and the length direction of the waist-shaped hole may be arranged along the vertical direction of the range hood. Of course, the third air inlet hole 501 may also be in other shapes, such as a round hole, a hexagonal hole, a diamond hole or a special-shaped hole, etc., which is not limited in this embodiment.

[0092] Preferably, two shell oil guide plates 5 of this embodiment may be relatively arranged inside the box body 2. Of course, the number of shell oil guide plates 5 may be one or more, which is not limited in this embodiment.

[0093] Combination Fig.11 as well as Fig.12 In this embodiment, buckles 7 are arranged at intervals on the top of each housing oil guide plate 5, and the top of each housing oil guide plate 5 is connected to the inner side of the top of the box body 2 through the buckle 7. Of course, the housing oil guide plate 5 can also be assembled on the inner side of the top of the box body 2 by bolts or other connection methods, and this embodiment does not limit this.

[0094] Combination Figure 5 , Figure 6 , Figure 7 as well as Fig.13 The range hood of this embodiment also includes a shell 8, which is connected and arranged at the middle position of the top of the box body 2. A fan 9 for providing wind power is installed in the shell 8, and two shell oil guide plates 5 can be arranged on the outside of both sides of the shell 8 in the horizontal direction.

[0095] Preferably, the opposing surfaces of the two shell oil guide plates 5 of this embodiment are flush with the two opposing horizontal lateral sides of the shell 8, so as to avoid increasing the air intake resistance of the range hood due to the arrangement of the two shell oil guide plates 5, so as to ensure the air intake volume of the range hood.

[0096] Furthermore, combined with Fig.10 as well as Fig.11 In this embodiment, the bottom of each shell oil guide plate 5 can be provided with an oil guide fold 6. The oil guide fold 6 of this embodiment can not only receive the oil droplets condensed on the side of the shell oil guide plate 6, so that the oil droplets transition smoothly and reduce the risk of oil droplets falling and flying out, but also increase the condensation area of ​​oil smoke and improve the oil guide efficiency. Finally, the oil guide fold 6 can enhance the strength of the shell oil guide plate and reduce the vibration caused by the poor strength of the shell oil guide plate 5 installed in the whole range hood, and has a good practical value.

[0097] Combination Figure 7 , Fig.12 as well as Fig.13 Preferably, the oil guide fold 6 of this embodiment can be arranged directly below the shell 8, that is, the oil guide fold 6 is only symmetrically arranged on the shell oil guide plate 5. Since the internal structure of the shell 8 is relatively complex and easy to store oil, the oil guide fold located directly below the shell 8 can receive the oil droplets inside the shell (especially the inner walls on the left and right sides of the shell), preventing the oil droplets from penetrating the air inlet net and falling onto the user's stove, thereby improving the user experience.

[0098] In this embodiment, the two sides of the length direction of the oil guide fold 6 can preferably conflict with the horizontal longitudinal sides (i.e., the front and rear sides) of the box body 2. In this way, the oil droplets received by the oil guide fold 6 can flow into the front and rear side walls of the box body 2 through the oil guide fold 6, the oil droplets flowing to the front side wall of the box body 2 are discharged to the oil receiving box 3 through the guide plate 4, and the oil droplets flowing to the rear side wall of the box body 2 can be drained to the oil receiving box 3 through the rear side wall of the box body 2, thereby avoiding the problem of oil droplet splashing and further improving the oil guide effect.

[0099] Furthermore, combined with Fig.11 , Fig.12 as well as Fig.13The oil guide fold 6 of this embodiment can be arranged at an angle. Preferably, the front height of the bottom of the oil guide fold 6 is higher than the rear height of the bottom of the oil guide fold 6. Since the oil receiving box 3 is arranged at the bottom of the rear side of the box body 2, the inclined oil guide fold 6 can guide the oil droplets received by the oil guide fold 6 to the rear side wall of the box body 2, and then guide them to the oil receiving box 3 through the rear side wall of the box body. Compared with the solution in which the oil droplets passing through the front side wall of the box body 2 are discharged to the oil receiving box 3 through the guide plate 4, this solution can reduce the path of the oil droplets, has a better oil guiding effect, and can further reduce the risk of oil droplets falling into the user's stove.

[0100] Combination Fig.12 In this embodiment, the oil guide fold 6 can have an inclination angle α with the horizontal direction, wherein 8°≤α≤30°, and 10°≤α≤20° is the best. This angle setting can speed up the oil guide speed and prevent oil droplets from accumulating and dripping during the oil guide process and penetrating the air inlet net.

[0101] Of course, oil guide flanges 6 may also be provided on both sides of the oil guide plate 5 of the housing, and this embodiment does not limit this.

[0102] Embodiment 4:

[0103] The present embodiment provides a range hood with a box oil guide plate, which is intended to at least to some extent solve the technical problem that oil droplets formed after condensation of oil fumes sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0104] Fig.14 It is the structural diagram of the oil guide plate of the box. Fig.15 for Fig.14 A front view of Fig.16 for Fig.13 The enlarged schematic diagram of E in FIG. Figure 14-16 In this embodiment, the box oil guide plate 10 is arranged inside the box 2 along the horizontal longitudinal direction of the box 2, the upper side of the box oil guide plate 10 is against the inner side of the top of the box 2, and the lower side of the box oil guide plate 10 is against the inner side of the guide plate 4.

[0105] Since the upper side of the box oil guide plate 10 of the present embodiment rests against the inner side of the top of the box 2, and the lower side of the box oil guide plate 10 rests against the inner side of the guide plate 4, that is, the top of the box 2 and the guide plate 4 are sealed by the box oil guide plate 10, the oil droplets formed after the condensation of the oil fume sucked away by the air inlet net can be guided along the box oil guide plate 10 to the guide plate, and guided along the guide plate 4 to the oil collecting box 3, thereby being able to solve to a certain extent the technical problem that the oil droplets formed after the condensation of the oil fume sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0106] Preferably, in the present embodiment, the box oil guide plate 10 is arranged between the air inlet net and the front side of the box 2, that is, the box oil guide plate 10 is arranged on the front side of the air inlet net, and the oil droplets formed after the condensation of the oil fume sucked away by the air inlet net can be guided along the box oil guide plate 10 to the air inlet net, and guided to the oil collecting box 3 along the air inlet net and the guide plate 4, thereby being able to solve to a certain extent the technical problem that the oil droplets formed after the condensation of the oil fume sucked away by the range hood through the air inlet net may drip along the air inlet net onto the user's stove, affecting the user experience.

[0107] Combination Fig.14 , Fig.15 as well as Fig.16 The box oil guide plate 10 of this embodiment may include a first plate body 1001, a second plate body 1002 and a third plate body 1003. The first plate body 1001 is against the inner side of the top of the box body 2, and the third plate body 1003 is against the front side of the guide plate 4. Moreover, the third plate body 1003 is arranged between the air inlet net and the front side wall of the box body 2, that is, the third plate body 1003 is arranged on the front side of the air inlet net, and the first plate body 1001 and the third plate body 1003 are connected through the second plate body 1002.

[0108] Furthermore, combined with Fig.14 , Fig.15 as well as Fig.16 , the second plate 1002 of this embodiment is connected to the side of the first plate 1001 facing the rear side wall of the box 2, that is, the second plate 1002 is arranged on the rear side of the first plate 1001, and the second plate 1002 is arranged on the side of the front side wall of the third plate 1003 facing the box 2, that is, the second plate 1002 is arranged on the front side of the third plate 1003, and the front side of the third plate 1003 is projected on the top of the box 2 and is located on the first plate 1001, that is, the front side of the third plate 1003 is projected on the top of the box 2 and is located between the front side and the rear side of the first plate 1001. That is, the box oil guide plate 10 of this embodiment is in a Z shape as a whole, and the second plate 1002 is arranged obliquely, which can extend the walking path of the oil droplets on the second plate 1002 to buffer the speed of the oil droplets, and prevent the oil droplets from being transferred to the air inlet net through the second plate 1002 due to excessive speed, causing the oil droplets to directly pass through the air inlet net and fall onto the user's stove.

[0109] Combination Fig.16 In this embodiment, the rear side of the first plate body 1001 can protrude from the front side wall of the shell body 8, that is, the first plate body 1001 has a receiving portion protruding from the shell body 8. In this way, the receiving portion of the first plate body 1001 can receive the oil droplets on the front side wall of the shell body 8, and then guide them to the inner side of the guide plate 4 through the second plate body 1002 and the third plate body 1003, and then guide them to the oil collecting box 3 by the guide plate 4.

[0110] In this embodiment, a plurality of bolt holes may be arranged at intervals on the first plate body 1001, and the first plate body 1001 is assembled on the top inner side of the box body 2 through a plurality of bolts, and a plurality of bolt holes may also be arranged at intervals on the third plate body 1003, and the third plate body 1003 is also assembled on the front side of the air inlet net through a plurality of bolts to realize the assembly of the box oil guide plate 10 in the box body 2.

[0111] Furthermore, the second plate 1002 of this embodiment also includes an upper plate 10021 for connecting to the first plate 1001 and a lower plate 10022 for connecting to the third plate 1003.

At this time, the first plate 1001 is arranged horizontally, and the angle between the upper plate 10021 and the first plate 1001 is an obtuse angle, which can improve the travel path of the oil droplets, buffer the dripping speed of the oil droplets, and prevent the oil droplets from passing through the air inlet net too fast and falling onto the user's stove.

[0114] In the present embodiment, the various components constituting the box oil guide plate 10 are preferably an integrally formed structure, so that the box oil guide plate 10 has sufficient strength, thereby reducing problems such as vibration caused by poor strength when the box oil guide plate 10 is installed in the range hood. In addition, the box oil guide plate and the front side of the box can form a closed space to prevent oil smoke from entering the closed space, and control modules, motors and other mechanisms can be installed in the closed space to reduce oil pollution and increase the service life of the above-mentioned mechanisms.

[0115] It should be noted that, in some embodiments, the box oil guide plate 10 may also only include the second plate body 1002, and the upper and lower ends of the second plate body 1002 are directly welded or integrally connected to the top inner side of the box body and the inner side of the guide plate, which can also achieve the effect of this embodiment.
