Description

Technical Field

[0001] The utility model relates to a range hood, in particular to an oil dripping prevention structure of the range hood. Background Art

[0002] Range hoods are electrical appliances used in home kitchens to remove fumes produced during cooking. They should not only perform their functional roles well, but also have decorative concepts that integrate with the modern kitchen layout. With the development of range hoods, range hoods are no longer limited to simple tools for removing kitchen fumes, but have added more entertainment functions and usage functions, such as entertainment range hoods with TV monitors, range hoods with security systems integrated with smart homes, and network range hoods with network control.

[0003] The existing range hood generally comprises a shell and a fan connected in the shell, the shell is provided with a smoke outlet, and the fan outlet is connected to the smoke outlet of the shell; the front side of the shell is connected with a lower baffle and an upper baffle edge, a smoke inlet is formed between the lower baffle and the upper baffle edge on the front side of the shell, and the shell is rotatably connected with the smoke inlet; when in use, by opening the fan and the upper baffle plate, the oil smoke produced by cooking enters the shell from the smoke inlet, and then is discharged from the smoke outlet through the guidance of the fan. After long-term use, the oil smoke carries oily substances, and the oil smoke is easy to form oil on the fan, and the oil liquid drips downward from the bottom of the fan shell under the force of gravity. Because the existing upper baffle plate is generally outward-opening, the upper baffle plate is generally flipped toward the outside of the shell. Therefore, when the oil liquid drips downward from the bottom of the fan shell, the oil liquid is easy to directly pass through the smoke inlet and drip onto the stove, or even pass through the smoke inlet and directly drip into the dishes being cooked, which brings customers a very poor user experience. Utility Model Content

[0004] The utility model aims to solve the technical problem of providing a range hood oil dripping prevention structure which can prevent oil from dripping from a smoke inlet.

[0005] In order to solve the above technical problems, the technical solution of the oil dripping prevention structure of a range hood in the utility model is:

[0006] The smoke exhaust gas fan of the present invention is connected with the smoke exhaust gas fan of the present invention, and the smoke exhaust gas fan of the present invention is connected with the smoke exhaust gas fan of the present invention.

[0007] The lower baffle is provided with a first abutment surface inclined downward from front to rear along the front side of the bottom end; the upper end of the lower baffle is provided with a second abutment surface matching the first abutment surface; the first abutment surface abuts against the rear side of the second abutment surface.

[0008] The rotating device includes a hinge; the left and right sides of the shell are both connected with rotating shafts, and the two rotating shafts are coaxial; the left and right sides above the upper baffle are both connected with hinges; the two hinges are rotatably connected to the two rotating shafts respectively.

[0009] The hinge is connected with the upper baffle through bolts.

[0010] The rear side of the lower baffle is connected to a second guide plate; the second guide plate is inclined downward from front to back; the front side of the rear wall of the shell is connected to a third guide plate; the third guide plate is inclined downward from back to front; the oil collecting box is located directly below the second guide plate and the third guide plate.

[0011] The guide seat is connected to two connecting ears; the two connecting ears are connected to the fan through bolts.

[0012] The technical effect that the utility model can achieve is: during use of the utility model, a range hood oil dripping prevention structure of the utility model, when oil is formed on the fan, the oil falls onto the guide seat through the oil leakage hole, and because the bottom wall of the guide seat is inclined downward from back to front, the oil will move forward along the bottom wall of the guide seat and fall onto the front upper side wall of the shell, and flow along the front upper side wall of the shell to the upper baffle edge, because the upper end of the upper baffle is located outside the shell, and the height of the upper end of the upper baffle is higher than the height of the lower end of the upper baffle edge, so the oil located on the upper baffle edge will fall onto the rear side wall of the upper baffle, and flow downward along the rear side wall of the upper baffle to the first guide plate, and then fall along the first guide plate to the lower part of the shell and finally be collected by the oil collecting box. Through the design of the upper baffle, the utility model makes it difficult for the oil to fall directly out of the smoke inlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 7 .

[0023] A range hood oil dripping prevention structure comprises a shell 1 and a fan 2 connected to the shell 1, a smoke outlet 3 is provided on the shell 1, the air outlet of the fan 2 is connected to the smoke outlet 3 of the shell 1, a lower baffle 9 and an upper baffle 10 are connected to the front side of the shell 1, and a smoke inlet is formed between the lower baffle 9 and the upper baffle 10 on the front side of the shell 1; an upper baffle 4 is rotatably connected to the smoke inlet of the shell 1, the upper end of the upper baffle 4 is rotatably connected to the shell 1 through a rotating device, and the upper baffle 4 is rotated into the shell 1 through the rotating device when in use; specifically, the rotating device comprises a hinge 21, and a rotating shaft 22 is connected to both left and right sides of the shell 1, and the two rotating shafts 22 are coaxial; hinges are connected to both left and right sides above the upper baffle 4 21, the two hinges 21 are rotatably connected to the two rotating shafts 22 respectively. More specifically, the hinges 21 are connected to the upper baffle plate 4 by bolts; the upper end of the upper baffle plate 4 is located outside the shell 1, and the upper end height of the upper baffle plate 4 is higher than the lower end height of the upper baffle edge 10; the lower end of the upper baffle plate 4 is connected with a lower baffle edge 11 to prevent the lower end of the upper baffle plate 4 from turning outward from the shell 1; specifically, a first abutment surface 12 inclined downward from front to rear is provided on the front side of the bottom end of the lower baffle edge 11, and a second abutment surface 13 matching the first abutment surface 12 is provided on the upper end of the lower baffle plate 9, and the first abutment surface 12 abuts against the rear side of the second abutment surface 13; the utility model can prevent the lower end of the upper baffle plate 4 from turning outward from the shell 1 through the lower baffle edge 11 (reference Figure 1 , Figure 4 ).

[0024] An oil leakage hole 5 is provided under the fan casing of the fan 2, and a guide seat 6 is connected to the bottom of the fan 2. The guide seat 6 is located directly below the oil leakage hole 5, and the bottom wall of the guide seat 6 is inclined downward from back to front; specifically, two connecting ears 33 are connected to the guide seat 6, and the two connecting ears 33 are connected to the fan 2 by bolts; a first guide plate 7 is connected to the bottom of the upper baffle 4, and the bottom of the first guide plate 7 is inclined downward from front to back, and an oil collecting box 8 is connected to the bottom of the casing 1.

[0025] Preferably, a second guide plate 31 is connected to the rear side of the lower baffle 9, and the second guide plate 31 is inclined downward from front to back; a third guide plate 32 is connected to the front side of the rear wall of the shell 1, and the third guide plate 32 is inclined downward from back to front; the oil collecting box 8 is located directly below the second guide plate 31 and the third guide plate 32.

[0026] When the utility model is in use, the fan 2 is turned on, and the upper baffle 4 is rotated toward the shell 1 to open the smoke inlet. At this time, the oil smoke enters the shell 1 through the smoke inlet and is discharged from the smoke outlet 3 through the guidance of the fan 2. When oil is formed on the fan 2, the oil is generally formed in the shell of the fan 2, and is discharged outward through the oil leakage hole 5 below the shell of the fan 2, and drips onto the guide seat 6. Because the bottom wall of the guide seat 6 is inclined downward from the back to the front, the oil on the guide seat 6 will flow along the bottom wall of the guide seat 6 and then drip out from the front end of the guide seat 6, and drip onto the front upper side wall of the shell 1 (reference Figure 1 ), and then flows along the front upper side wall of the shell 1 to the upper baffle 10. Because the upper end of the upper baffle 4 of the utility model is located outside the shell 1, and the upper end height of the upper baffle 4 is higher than the lower end height of the upper baffle 10 (reference Figure 3 ), so when the oil drips from the upper baffle 10, the oil generally drips directly on the rear side of the upper baffle 4, and does not directly drip out from the smoke inlet between the lower baffle 9 and the upper baffle 10 on the front side of the shell 1 (that is, the utility model can prevent the oil from dripping from the smoke inlet through the setting of the upper baffle 4). This method does not affect the cleanliness of the stove, and it is relatively clean; and when the oil drips onto the rear side of the upper baffle 4, the oil will go down along the rear side of the upper baffle 4. The oil flows until it flows onto the first guide plate 7, and falls downward along the first guide plate 7, and the oil falls on the rear side wall of the lower baffle plate 9 or the second guide plate 31 or the third guide plate 32, and is finally collected in the oil collecting box 8 through the guidance of the rear side wall of the lower baffle plate 9 or the second guide plate 31 or the third guide plate 32. The utility model adopts the above design so that the oil is not easy to drip out from the smoke inlet between the lower baffle plate 9 and the upper baffle edge 10 on the front side of the shell 1, and it is cleaner when used.
