Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and in particular to an oil dripping prevention technology for side-smoking range hoods. Background Art

[0002] At present, the smoke outlet of the upper range hood on the market is usually opened by a flap. During use, before the oil smoke is sucked into the interior of the range hood, some of the oil smoke will condense into oil droplets on the inner side of the flap. The accumulation of oil on the inner side of the flap may cause the risk of oil dripping, which may drip directly onto the stove, increasing the user's cleaning work and affecting the user experience.

[0003] To avoid the risk of oil dripping, some manufacturers install oil collecting and guiding devices on the inner side of the flap of the side-suction range hood. For example, the Chinese invention patent with publication number CN108240645A discloses an oil collecting and unloading device for the smoke guide plate of a close-suction range hood. When the smoke guide plate is opened, the oil on the back of the smoke guide plate is received by the oil collecting part. When the smoke guide plate is closed, the oil collecting part is driven to rotate by the rotation of the motor, so that the oil in the oil guide part is guided into the lower panel and finally flows into the oil cup. The structure of the oil collecting and unloading device is relatively complex, occupies a large volume, and is expensive. Summary of the Invention

[0004] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, the present invention proposes an anti-drip oil side smoking machine, which has a simple and ingenious structure and effectively solves the risk of oil dripping when the flap of the side smoking machine is opened.

[0005] According to the above-mentioned anti-drip oil side smoking hood, it is achieved through the following technical solutions:

[0006] The smoke extractor is a smoke extractor with an anti-drip oil function, comprising a smoke collecting hood with a smoke inlet, a flap and a driving mechanism, wherein the flap is rotatably arranged at the smoke inlet, the driving mechanism is arranged on the smoke collecting hood and connected to the flap, and further comprising an anti-drip oil device, the anti-drip oil device comprising an upwardly opening oil collecting box and an oil leakage channel, the oil collecting box being mounted on the lower back side of the flap, at least part of the oil leakage channel being arranged in the oil collecting box and being provided with an overflow port connected to the oil collecting box, the overflow port being located between the bottom surface of the oil collecting box and the upper end surface of the side wall; when the flap is opened, oil droplets on the back side of the flap are collected in the oil collecting box, and the maximum oil storage capacity of the oil collecting box when the flap is open is greater than its maximum oil storage capacity when the flap is closed.

[0007] In some embodiments, a gap is left between the inner wall of the oil leakage channel and the inner wall of the oil collecting box, and the outer wall of the oil leakage channel abuts against the outer wall of the oil collecting box, or the outer wall of the oil leakage channel constitutes a partial outer wall of the oil collecting box.

[0008] In some embodiments, the anti-drip oil device also includes an oil baffle, the overflow port is arranged at the top of the oil leakage channel, the oil baffle is arranged at the upper end of the overflow port and its projection on the overflow port covers the overflow port, and a gap for oil drips to pass through is formed between the oil baffle and the outer wall of the oil collecting box.

[0009] In some embodiments, the oil baffle is a guide plate, one side of the guide plate is connected to the outer side wall of the oil collecting box or the oil leakage channel, and the other side extends obliquely upward.

[0010] In some embodiments, the oil baffle is formed by cutting a portion of the outer wall of the oil collecting box and bending the portion toward the top of the overflow port, and the gap between the oil baffle and the outer wall of the oil collecting box forms the pore.

[0011] In some embodiments, the upper end of the oil leakage channel is closed, and the overflow port is provided at the upper end of the side wall of the oil leakage channel.

[0012] In some embodiments, the top surface of the oil leakage channel is a guide surface that is an inclined surface or an arc surface.

[0013] In some embodiments, a V-shaped or U-shaped groove is provided at the upper end of the inner side wall of the oil collecting box, and the lowest point of the groove is higher than the overflow port.

[0014] In some embodiments, the oil leakage channel is arranged in the oil collecting box and is integrally formed with the oil collecting box. An opening is provided on the bottom surface of the oil collecting box at a position corresponding to the oil leakage channel. The opening constitutes the outlet of the oil leakage channel. When the flap is closed, the outlet of the oil leakage channel is connected to the interior of the smoke hood.

[0015] In some embodiments, an oil cup is further included, which is arranged on the outer side of the bottom of the smoke hood. An oil leakage hole is provided at a position on the bottom of the smoke hood corresponding to the position where the oil cup is provided, and the oil leakage hole is connected to the oil cup.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. In the side-mounted smoker of the present invention, the oil collection box is connected to the oil leakage channel through the overflow port. The oil collection box is designed so that the maximum oil storage capacity when the flap is open is greater than the maximum oil storage capacity when the flap is closed. This effectively ensures that the oil in the oil collection box will only flow from the overflow port into the oil leakage channel when the flap is closed, preventing oil from dripping onto the stovetop when the flap is opened. This solves the risk of oil dripping when the flap of the side-mounted smoker is opened, and improves the user experience.

[0018] 2. Compared with the existing oil collecting and unloading devices, the anti-drip oil device of the present invention has a simpler and more ingenious structure, high reliability, small space occupation, lower manufacturing and user costs, and improves product competitiveness.

[0027] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0028] Example 1

[0029] like Figure 1-7As shown, this embodiment provides a side-mounted smoke hood with an anti-drip oil feature, comprising a smoke hood 1, a flap 2, an anti-drip oil device 3 mounted on the lower back side of the flap 2, and a drive mechanism 5. The front of the smoke hood 1 is provided with a smoke inlet 101 and a curved smoke guide plate 11 located below the smoke inlet 101. The flap 2 is rotatably mounted at the smoke inlet 101 for opening or closing the smoke inlet 101. The drive mechanism 5 is mounted on the smoke hood 1 and connected to the flap 2, for driving the flap 2 to rotate to open or close the smoke inlet 101. The anti-drip oil device 3 includes an upwardly opening oil collecting box 31 and an oil leakage channel 32. The oil collecting box 31 is installed on the lower side of the back of the flap 2 to collect oil droplets on the back of the flap 2; at least part of the oil leakage channel 32 is arranged in the oil collecting box 31 and it is provided with an overflow port 321 connected to the oil collecting box 31. The overflow port 321 is located between the bottom surface and the upper end surface of the side wall of the oil collecting box 31. In this way, when the oil storage amount in the oil collecting box 31 reaches the overflow port 321, it flows into the oil leakage channel 32 from the overflow port 321. Preferably, when the flap 2 is opened, the oil droplets on the back of the flap 2 are directly collected in the oil collecting box 31. When the flange 2 is closed, the outlet 322 of the oil leakage channel 32 is connected to the interior of the smoke hood 1, and the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is open is greater than its maximum oil storage capacity when the flap 2 is closed. In this way, it is effectively ensured that the oil in the oil collecting box 31 can only flow out from the overflow port 321 when the flap 2 is closed, and flow into the interior of the smoke hood 1 through the oil leakage channel 32.

[0030] As can be seen, in the side-mounted smoker of this embodiment, the oil collection box 31 is connected to the oil leakage channel 32 through the overflow port 321, and the oil collection box 31 is designed so that the maximum oil storage capacity when the flap 2 is open is greater than its maximum oil storage capacity when the flap 2 is closed. This effectively ensures that the oil in the oil collection box 31 can only flow from the overflow port 31 into the oil leakage channel 32 when the flap 2 is closed, preventing oil from dripping onto the stove when the flange 2 is opened. This solves the risk of oil dripping from the flange 2 of the side-mounted smoker and improves the user experience. In addition, compared to existing oil collection and oil unloading devices, the anti-drip oil device 3 of the present invention has a simpler and more ingenious structure, high reliability, small space occupation, lower manufacturing and user costs, and improves product competitiveness.

[0031] In this embodiment, the front of the side smoking machine is taken as the front, the side walls of the oil collecting box 31 and the oil leakage channel 32 close to the flange 2 are the outer walls, and correspondingly, the side walls of the oil collecting box 31 and the oil leakage channel 32 away from the flange 2 are the inner walls.

[0032] Preferably, the outer wall of the oil collection box 31 in this embodiment is fixedly attached to the lower back side of the flange 2 by bonding. This increases the effective contact area between the oil collection box 31 and the back side of the flange 2, thereby enhancing the securement and reliability of the connection between the oil collection box 31 and the flange 2. Furthermore, the length of the oil collection box 31 is slightly smaller than the width of the flange 2, and the bottom surface of the oil collection box 31 is flush with the bottom surface of the flange 2. This ensures that the oil collection box 31 catches nearly all oil dripping from the back side of the flap 2, preventing oil dripping from the back side of the flange 2 from dripping onto the stovetop when the flange 2 is opened. This also prevents the oil collection box 31 from interfering with the flipping and opening and closing movement of the flange 2.

[0033] like Figure 2-3 As shown, preferably, there is a distance between the inner wall of the oil leakage channel 32 and the inner wall of the oil collecting box 31, and the outer wall of the oil leakage channel 32 constitutes a partial outer wall of the oil collecting box 31. In this way, not only the outer wall of the oil leakage channel 32 can be omitted, manufacturing materials can be saved, and costs can be reduced, but also the maximum oil storage capacity of the oil collecting box 31 when the flange 2 is opened can be further increased, ensuring that the oil inside the oil collecting box 31 will not drip onto the stove, thereby improving the user experience.

[0034] In other embodiments, the outer wall of the oil leakage channel 32 may be configured to abut against the outer wall of the oil collecting box 31 , or a distance may be left between the outer wall of the oil leakage channel 32 and the outer wall of the oil collecting box 31 .

[0035] Preferably, the top of the oil leakage channel 32 has an upward opening, and the upward opening of the oil leakage channel 32 constitutes an overflow port 321. Thus, by arranging the overflow port 321 at the top of the oil leakage channel 32, the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is opened is further increased (see FIG. Figure 5 ), on the other hand, it increases the oil inlet area of each oil leakage channel 32 and reduces the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is closed (see Figure 7 ), thereby increasing the difference in the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is opened and closed, ensuring that the oil droplets in the oil collecting box 31 will only flow out from the overflow port 321 near the outside of the flange 2 when the flap 2 is opened, solving the risk of oil dripping in the side-mounted smoking machine.

[0036] More preferably, the oil leakage channel 32 is disposed within the oil collecting box 31 and is integrally formed therewith. The bottom surface of the oil collecting box 31 is provided with an opening corresponding to the oil leakage channel 32. This opening constitutes an outlet 322 of the oil leakage channel 32. When the flap 2 is closed, the outlet 322 of the oil leakage channel 32 communicates with the interior of the fume hood 1. Thus, the integral formation of the oil leakage channel 32 within the oil collecting box 31 not only facilitates the rapid fabrication of the anti-drip device 3 but also improves the seal between the oil leakage channel 32 and the oil collecting box 31, preventing oil dripping at the connection between the two.

[0037] In this embodiment, oil leakage channels 32 arranged in a row along the length direction are integrally formed inside the oil collecting box 31. All the oil leakage channels 32 are evenly spaced and arranged side by side, and each oil leakage channel 32 is connected to the oil collecting box 31 through the overflow port 321. In this way, the unit oil discharge area and automatic oil discharge capacity of the oil collecting box 31 are improved by using a plurality of evenly spaced and side-by-side oil leakage channels 32, which effectively ensures that when the flap 2 is opened, the oil in the oil collecting box 31 will not flow out from the overflow port 321 and drip, thereby ensuring the oil dripping capacity of the anti-drip device 3 when the flap 2 is opened.

[0038] like Figure 2-3 、 Figure 5 and Figure 7 As shown, further, the anti-drip oil device 3 also includes an oil baffle 33, and an oil baffle 33 is arranged above each overflow port 321. The projection of the oil baffle 33 on the overflow port 321 covers the overflow port 321, and is used to prevent the oil droplets on the back of the flap 2 from directly flowing into the overflow port 321 when the flap 2 is opened, thereby eliminating the condition where the oil droplets on the back of the flap 2 drip onto the stove to form the risk of oil dripping. A gap 301 for oil droplets to pass through is formed between the oil baffle 33 and the outer wall of the oil collecting box 31. The gap 301 is connected to the interior of the oil storage box 31. In this way, when the oil droplets on the back of the flap 2 flow down from above the oil baffle 33, they are affected by the oil baffle 33 and cannot directly enter the overflow port 321. Instead, they flow into the oil collecting box 31 from the gap 301 between the oil baffle 33 and the outer wall of the oil collecting box 31. When the flap is closed and the oil storage amount inside the oil storage box 31 exceeds the liquid level line, the oil will flow into the oil leakage channel 32 from the overflow port 321 and rely on its own gravity to flow to the interior of the smoke collecting hood 1, that is, the back of the smoke guide plate 11.

[0039] Preferably, the oil baffle 33 is a guide vane, one side of which is connected to the outer wall of the oil collecting box 31 or the oil leakage channel 32, and the other side of which extends diagonally upward. Apertures 301 are formed between both sides of the guide vane and the outer wall of the oil collecting box 31. Thus, by designing the oil baffle 33 as a guide vane, oil droplets that drip onto the oil baffle 33 are better guided into the apertures 301 on both sides of the oil baffle 33, flowing into the oil collecting box 31. This effectively prevents oil droplets on the back of the flange 2 from flowing directly into the overflow port 321, thereby resolving the oil leakage problem in side-mounted smokers.

[0040] More preferably, each oil baffle 33 (i.e., guide plate) is formed by cutting a portion of the outer wall of the oil collecting box 31 and then bending it diagonally upward. The gap between the oil baffle 33 and the outer wall of the oil collecting box 31 forms the aperture 301. This facilitates rapid molding of the oil baffle 33, improves the utilization rate of the partial outer wall of the oil collecting box 31, and also saves manufacturing materials and reduces the number of steps required to connect the oil baffle 33 to the oil collecting box 31. In addition, after the partial outer wall of the oil collecting box 31 is bent diagonally upward to form the oil baffle 33, a "U"-shaped notch that narrows from top to bottom is formed on the outer wall of the oil collecting box 31. This further facilitates the diversion of oil droplets on the back of the flap 2 from the "U"-shaped notch to the aperture 301.

[0041] like Figure 4 As shown, the smoke hood 1 further includes an oil cup 4, which is arranged on the outside of the bottom of the smoke hood 1. An oil leakage hole 102 is provided at the bottom of the smoke hood 1 at a position corresponding to the position of the oil cup 4, and the oil leakage hole 102 is connected to the oil cup 4. When the flap 2 is closed and the oil storage volume inside the oil storage box 31 exceeds the liquid level line, the oil flows from the overflow port 321 into the oil leakage channel 32, flows into the interior of the smoke hood 1 by its own gravity, and is guided downward along the back of the smoke guide plate 11 to the inner bottom of the smoke hood 2, and flows into the oil cup 4 from the oil leakage hole 102. This prevents oil stains from the side-mounted smoke hood from dripping onto the stove, reduces the user's workload of cleaning the stove, and improves the user experience.

[0042] The following combination Figure 4-7 To illustrate the oil droplet path of the side smoking hood of this embodiment:

[0043] like Figure 4-5 As shown, the flap 2 is in the open state, and the overflow port 321 is lower on the side away from the oil baffle 33. Since the side of the oil collecting box 31 away from the flap 2 is lower than the side close to the flap 2, the oil storage capacity of the oil collecting box 31 increases when the flap 2 is opened, ensuring that the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is open is greater than the maximum oil storage capacity when the flap 2 is closed. When the oil smoke condenses into oil droplets on the back of the flap 2, the oil droplets are guided downward along the back of the flap 2 to the "U"-shaped recess, and flow into the oil collecting box 31 from the pores 301 on both sides of the oil baffle 33. Due to the blocking effect of the oil baffle 33, the oil droplets on the back of the flap 2 cannot directly enter the overflow port 321, thereby preventing the oil droplets from dripping directly onto the stove, effectively solving the oil dripping problem of the side-mounted smoker and improving the user experience.

[0044] like Figure 6-7As shown, the flap 2 is in a closed state, the overflow port 321 is lower on the side close to the oil baffle 33, and the outlet 322 of the oil leakage channel 32 is connected to the inside of the smoke hood 1. Moreover, since the side of the oil collecting box 31 away from the flap 2 is upturned and higher than the side close to the flap 2, the oil storage capacity of the oil collecting box 31 is reduced when the flap 2 is closed, ensuring that the maximum oil storage capacity of the oil collecting box 31 when the flap 2 is closed is lower than the maximum oil storage capacity when the flap 2 is opened. In this way, when the amount of oil in the oil collecting box 31 exceeds the high liquid line, it flows from the overflow port 321 into the oil leakage channel 32, flows from the outlet 322 of the oil leakage channel 32 to the back of the smoke guide plate 11, flows to the oil leakage hole 102 under the guidance of the smoke guide plate 11, and flows into the oil cup 4 from the oil leakage hole 102, thereby realizing the unified collection and dumping of oil by the oil cup 4.

[0045] Example 2

[0046] like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the structure of the oil leakage channel 32 is different. Specifically, the upper end of the oil leakage channel 32 is closed, and the overflow port 321 is provided at the upper end of the rear side wall of the oil leakage channel 32. Preferably, the overflow port 321 of this embodiment is provided close to the top of the oil leakage channel 32 to increase the oil storage capacity of the oil collecting box 31 when the flap 2 is opened and closed. The top surface of the oil leakage channel 32 is a guide surface in the form of an inclined surface or an arc surface, so as to guide the oil droplets dripping to the top of the oil leakage channel 32 into the oil collecting box 31, thereby avoiding the accumulation of oil droplets at the top of the oil leakage channel 32. In other embodiments, the overflow port 321 can also be provided at the upper end of the left side wall and / or right side wall of the oil leakage channel 32.

[0047] In addition, a V-shaped or U-shaped groove 311 is provided at the upper end of the inner sidewall of the oil collecting box 31. The lowest point of the groove 311 is higher than the overflow port 321. The groove 311 is located directly above the top of the oil leakage channel 32. This effectively guides oil droplets flowing from the back of the flap 2 through the groove 311 to the top of the oil leakage channel 32, and then flows into the oil collecting box 31 through the gap between the top of the oil leakage channel 32 and the outer sidewall of the oil collecting box 31. All other parts are the same as those in Example 1.

[0048] When flap 2 is open, oil droplets on the back of flap 2 flow downward along the back of flap 2, are guided through slot 311 to the top surface of oil leakage channel 32, and then flow into oil collection box 31 through the gap between the top surface of oil leakage channel 32 and the outer wall of oil collection box 31. When flap 2 is closed, the flow path of oil inside oil collection box 31 is the same as in Example 1 and will not be further described here.

[0049] It can be seen that by closing the top of the oil leakage channel 32 and setting the overflow port 321 at the upper end of the front side wall of the oil leakage channel 32 and close to its top surface, there is no need for the oil baffle as described in Example 1, so as to prevent the oil droplets on the back of the flap 2 from flowing directly out of the overflow port 321 and prevent the oil droplets from falling onto the stove, effectively solving the risk of oil dripping from the side smoking machine; at the same time, the overflow port 321 is set at the upper end of the front side wall of the oil leakage channel 32 and close to its top surface, so that the oil storage capacity of the oil collecting box 31 is larger when the flap 2 is closed.

[0050] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
