Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically to a range hood that prevents oil dripping. Background Technology

[0002] Range hoods are an important kitchen appliance. Their main function is to help remove fumes, steam, and odors produced during cooking, thereby maintaining fresh air and a hygienic environment in the kitchen. During cooking, especially when stir-frying, a lot of fumes are produced. Range hoods usually use a fan to suck up the fumes from the air and then exhaust them outdoors through an exhaust pipe, or they use a built-in filter to purify and recirculate the fumes.

[0003] Chinese Patent Publication No. CN108775609A discloses an easy-to-clean range hood, comprising a range hood body, an oil filter, and a panel. The oil filter is installed at an angle relative to the horizontal plane at the lower end of the range hood body. An oil guide plate is provided on the outer side of the lower end of the oil filter on the range hood body, with a certain distance maintained between the oil filter and the oil guide plate. The panel is located outside the oil filter and is slidably mounted on the range hood body parallel to the oil filter to control the opening and closing of the oil filter. This invention maintains a certain distance between the lower end of the oil filter and the oil guide plate, so that the grease on the oil filter drips directly onto the oil guide plate, preventing grease accumulation, thus facilitating cleaning, ease of use, and high oil drainage efficiency.

[0004] The aforementioned patent mentions that the grease adhering to the oil filter of the range hood can quickly drip from the bottom of the oil filter to the oil guide plate, and then be guided by the oil guide plate into the oil collection area at the bottom of the oil collection tank, and then collected into the oil cup through the oil leakage hole. However, because oil mist sometimes adheres to the oil filter and drips due to gravity, and the oil mist has poor flow after adhering to the oil filter, some oil mist easily condenses into large drops of grease that stay above the oil filter and are difficult to drip to the oil guide plate, causing oil droplets to accumulate above the oil filter and easily drip directly into the pot. Therefore, we propose a range hood that prevents grease from dripping. Utility Model Content

[0005] To address the aforementioned issues, a range hood designed to prevent oil dripping is provided. A displacement system drives the oil-absorbing component to reciprocate along the surface of the smoke extraction panel, allowing it to absorb large oil droplets remaining on the panel surface. This prevents these large droplets from dripping directly into the pot, solving the problem of oil mist easily condensing into large droplets that remain above the oil filter and fail to drip onto the guide plate, causing oil droplets to accumulate above the oil filter and easily drip directly into the pot.

[0006] To address the problems of existing technologies, this utility model provides a range hood that prevents oil dripping, comprising a range hood body, a smoke extraction panel on the range hood body, an oil collection cover on the side of the range hood body near the smoke extraction panel, an oil-absorbing component on the outer side of the smoke extraction panel for absorbing oil stains on the surface of the smoke extraction panel; a connecting rod for supporting the oil-absorbing component and maintaining its cylindrical shape; a displacement system between the range hood body and the connecting rod for driving the connecting rod to move the oil-absorbing component; and a clamping mechanism on the connecting rod for confining the oil-absorbing component to the outer side of the connecting rod.

[0007] Preferably, the displacement system includes a reciprocating sleeve and a reciprocating lead screw; the reciprocating sleeve is rotatably mounted on the connecting rod; the reciprocating lead screw is rotatably mounted on the range hood body, and the reciprocating lead screw is connected to the reciprocating sleeve.

[0008] Preferably, the displacement system further includes a transmission mechanism and a rotation mechanism; the transmission mechanism is disposed between the range hood body and the reciprocating screw, and the transmission mechanism is used to synchronously drive the reciprocating screw to rotate; the rotation mechanism is disposed between the range hood body and the reciprocating sleeve, and the rotation mechanism is used to drive the oil suction component to rotate.

[0009] Preferably, the transmission mechanism includes a sprocket assembly and a power component; the sprocket assembly is rotatably mounted on the range hood body, and the working end of the sprocket assembly is connected to one end of the reciprocating lead screw; the power component is mounted on the range hood body, and the output end of the power component is connected to the working end of one side of the sprocket assembly.

[0010] Preferably, the rotating mechanism includes a toothed disc and a rack; the toothed disc is fixedly connected to a connecting rod, and the toothed disc is rotatably connected to a reciprocating sleeve; the rack meshes with the toothed disc, and the rack is fixedly connected to the main body of the range hood.

[0011] Preferably, the connecting rod is provided with a clamping mechanism, which is used to restrict the oil-absorbing component to the outside of the connecting rod. The clamping mechanism includes a connecting plate, a connecting pad, and a conical block. The connecting plate is rotatably mounted on the connecting rod. The connecting pad is fixedly connected to the connecting rod and the connecting plate respectively. The conical block is fixedly connected to the side of the connecting plate away from the connecting pad.

[0012] Preferably, the clamping mechanism further includes a locking assembly for restricting the connecting plate to the outside of the connecting rod. The locking assembly includes a locking strip and a locking plate; the locking strip is fixedly connected to the connecting plate; the locking plate abuts against the locking strip and is fixedly connected to the connecting rod.

[0013] Preferably, one end of the connecting plate has a groove that runs through both sides of the connecting plate. The groove is used to cooperate with the connecting plate to drive the locking strip to disengage from the locking plate.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. The oil-absorbing component is driven by a displacement system to move back and forth along the surface of the smoke extraction panel, allowing it to absorb large drops of oil residue left on the surface of the smoke extraction panel. This prevents large drops of oil from dripping directly into the pot, thus solving the problem that some oil mist easily condenses into large drops of oil that remain above the oil mesh and are difficult to drip onto the oil guide plate, causing oil droplets to accumulate above the oil mesh and easily drip directly into the pot.

[0016] 2. The clamping mechanism enables quick disassembly and replacement of the oil suction component from the connecting rod, improving the convenience and efficiency of the oil suction component replacement operation. This solves the technical problems of cumbersome oil suction component replacement operation, low disassembly efficiency, resulting in insufficient maintenance convenience and high cleaning and maintenance costs of the range hood.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1-4 As shown, a range hood designed to prevent oil dripping includes a main body 1, a smoke extraction panel 11 on the main body 1, an oil collection hood 12 on the side of the main body 1 near the smoke extraction panel 11, and an oil-absorbing component 2 on the outer side of the smoke extraction panel 11 for absorbing oil stains on the surface of the smoke extraction panel 11. The oil-absorbing component 2 is equipped with a connecting rod 21 for supporting the oil-absorbing component 2 and maintaining its cylindrical shape. A displacement system is provided between the main body 1 and the connecting rod 21 for driving the connecting rod 21 to move the oil-absorbing component 2. The connecting rod 21 is equipped with a clamping mechanism for... The oil-absorbing component 2 is confined to the outside of the connecting rod 21; the displacement system includes a reciprocating sleeve 22 and a reciprocating lead screw 23; the reciprocating sleeve 22 is rotatably mounted on the connecting rod 21; the reciprocating lead screw 23 is rotatably mounted on the range hood body 1, and the reciprocating lead screw 23 is connected to the reciprocating sleeve 22; the displacement system also includes a transmission mechanism and a rotation mechanism; the transmission mechanism is located between the range hood body 1 and the reciprocating lead screw 23, and the transmission mechanism is used to synchronously drive the reciprocating lead screw 23 to rotate; the rotation mechanism is located between the range hood body 1 and the reciprocating sleeve 22, and the rotation mechanism is used to drive the oil-absorbing component 2 to rotate.

[0026] Specifically, the oil-absorbing component 2 uses oil-absorbing cotton strips as the implementing element. The reciprocating sleeve 22 and the reciprocating lead screw 23 form a transmission guide pair.

[0027] When the range hood is running, some of the oil mist condenses into large droplets of grease on the surface of the smoke extraction panel 11. At this time, the oil-absorbing component 2 is fixed to the outside of the connecting rod 21 using a clamping mechanism, and then the two reciprocating screws 23 are synchronously driven to rotate through a transmission mechanism. Since the reciprocating sleeve 22 and the reciprocating screw 23 form a transmission guide pair, the reciprocating sleeve 22 can move back and forth linearly along the reciprocating screw 23, thereby causing the reciprocating sleeve 22 to move the connecting rod 21. The connecting rod 21 drives the oil-absorbing component 2 to move back and forth linearly, allowing the oil-absorbing component 2 to wipe the surface of the smoke extraction panel 11. Thanks to the use of oil-absorbing cotton strips as the implementing element, and the oil-absorbing properties of the oil-absorbing cotton strips, the oil-absorbing component 2 can effectively remove the grease from the surface of the smoke extraction panel 11. In addition, during the movement of the oil-absorbing component 2, the rotating mechanism drives the oil-absorbing component 2 to rotate, so that the oil-absorbing component 2 rotates in the opposite direction while moving in a straight line, which makes it easier for the oil stains on the surface of the smoke extraction panel 11 to be thoroughly removed, avoids cleaning dead corners, improves the cleaning efficiency of the oil-absorbing component 2, and prevents large drops of oil stains from dripping directly into the pot.

[0028] See Figures 1-6As shown, the transmission mechanism includes a sprocket assembly 24 and a power component 25; the sprocket assembly 24 is rotatably mounted on the range hood body 1, and the working end of the sprocket assembly 24 is connected to one end of the reciprocating screw 23; the power component 25 is mounted on the range hood body 1, and the output end of the power component 25 is connected to the working end of one side of the sprocket assembly 24; the rotating mechanism includes a gear plate 26 and a rack 27; the gear plate 26 is fixedly connected to the connecting rod 21, and the gear plate 26 is rotatably connected to the reciprocating sleeve block 22; the rack 27 meshes with the gear plate 26, and the rack 27 is fixedly connected to the range hood body 1.

[0029] Specifically, the sprocket assembly 24 consists of meshing sprockets and chains. The power unit 25 uses an electric motor as the implementing element.

[0030] When the range hood is running, the power unit 25 starts synchronously, and the output end of the power unit 25 drives the sprocket on one side of the sprocket assembly 24 to rotate. Since the sprocket assembly 24 is composed of meshing sprockets and chains, the rotational power of the power unit 25 can be transmitted to the reciprocating screws 23, causing the two reciprocating screws 23 to rotate synchronously. During the rotation of the reciprocating screws 23, the reciprocating sleeve block 22 that cooperates with them drives the connecting rod 21 to perform reciprocating linear motion. At the same time, the reciprocating sleeve block 22 drives the gear plate 26 to move along the rack 27. Since the gear plate 26 and the rack 27 are meshed, the gear plate 26 drives the connecting rod 21 to rotate during the movement. In this way, the connecting rod 21 can drive the oil suction component 2 to rotate while performing reciprocating linear motion, thereby improving the cleaning effect of the oil suction component 2 on the smoke extraction panel 11. Furthermore, deformable folding covers can be fitted at both ends of the reciprocating screw 23, and the deformable folding covers are connected to the reciprocating sleeve block 22. When the reciprocating sleeve block 22 moves, the deformable folding covers extend or retract accordingly, thereby preventing oil stains from adhering to the surface of the reciprocating screw 23. The sprocket assembly 24 is located inside the range hood body 1 and will not be affected by oil stains.

[0031] See Figures 3-4 As shown, the clamping mechanism includes a connecting plate 28, a connecting pad 29, and a conical block 210. The connecting plate 28 is rotatably mounted on the connecting rod 21. The connecting pad 29 is fixedly connected to both the connecting rod 21 and the connecting plate 28. The conical block 210 is fixedly connected to the side of the connecting plate 28 away from the connecting pad 29. The clamping mechanism also includes a locking assembly, which is used to restrict the connecting plate 28 to the outside of the connecting rod 21. The locking assembly includes a locking strip 211 and a locking plate 212. The locking strip 211 is fixedly connected to the connecting plate 28. The locking plate 212 is mated with the locking strip 211 and fixedly connected to the connecting rod 21. One end of the connecting plate 28 has a groove 213 that runs through both sides of the connecting plate 28. The groove 213 is used to cooperate with the connecting plate 28 to drive the locking strip 211 to disengage from the locking plate 212.

[0032] Specifically, the connecting pad 29 is made of deformable rubber and maintains compressive contact with the smoking panel 11. The card plate 212 is made of deformable plastic.

[0033] When the oil-absorbing component 2 needs to be fixed to the outside of the connecting rod 21, use a tool or your finger to hold the groove 213 and pull the connecting plate 28 outward to provide the user with convenient rotation opening conditions. After the connecting plate 28 is rotated open, it presses the two sides of the oil-absorbing component 2 into contact with the conical block 210, causing the conical block 210 to penetrate the oil-absorbing component 2. Then, press the connecting plate 28 to drive the locking strip 211 to press and connect with the locking plate 212. During this process, the locking strip 211 simultaneously pushes the oil-absorbing component 2 and the locking plate 212 to press against each other. Because the card plate 212 is made of deformable plastic material, it bends under force. When the card strip 211 enters the inside of the card plate 212, the card plate 212 returns to its initial shape, thereby forming a restrictive constraint relationship between the card strip 211, the oil-absorbing component 2 and the card plate 212, realizing the stable fixation of the oil-absorbing component 2 on the outside of the connecting rod 21, so that the oil-absorbing component 2 can move with the connecting rod 21. Because the connecting pad 29 is made of deformable rubber material, and the connecting pad 29 maintains a squeezing contact with the smoke extraction panel 11, the wiping operation of the oil on the smoke extraction panel 11 is completed.

[0034] When the oil suction component 2 needs to be replaced, the user can simply pull the connecting plate 28, which will cause the connecting plate 28 to move the locking strip 211 away from the locking plate 212. At the same time, the connecting plate 28 can be rotated open, thereby realizing the quick disassembly and replacement of the oil suction component 2 from the connecting rod 21, improving the convenience and efficiency of the oil suction component 2 replacement operation.

[0035] Working principle: When the range hood is running, the conical block 210 passes through both sides of the oil-absorbing component 2 and presses down on the connecting plate 28, thus firmly fixing the oil-absorbing component 2 to the outside of the connecting rod 21. Then, the range hood body 1 and the power component 25 start synchronously. The power component 25 drives the two reciprocating screws 23 to rotate synchronously, thereby causing the connecting rod 21 to perform reciprocating linear motion. At the same time, the connecting rod 21 drives the oil-absorbing component 2 to rotate and wipe the oil stains on the surface of the smoke extraction panel 11, thereby improving the cleaning effect of the oil-absorbing component 2 on the smoke extraction panel 11.

[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
