Specifically: First, some of the oil fumes and moisture are intercepted and condensed as they pass through the air inlet on the front panel. The condensed grease and water adhere to the end face of the front panel near the filter assembly and then flow under gravity, eventually being guided into the oil cup through the first oil guide. Then, most of the grease and moisture are intercepted by the filter assembly. The condensed grease and water adhere to the filter assembly and flow under gravity, eventually flowing into the oil cup. Throughout this process, the filter assembly intercepts and purifies the oil fumes and moisture. Furthermore, the filter assembly, in conjunction with the first oil guide, forms multiple oil paths to guide the condensed grease and water, preventing them from flowing out of the oil cup. This improves the collection efficiency of grease and water, enhances the performance of the countertop range hood, and ensures a better user experience.

[0046] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] The tabletop range hood provided in this embodiment includes: a front panel 100, a filter assembly 200, a housing 300, an oil cup 400, and a fan assembly 500. The front panel 100 covers the open end of the housing 300.

[0048] Both the filter assembly 200 and the fan assembly 500 are housed within the housing 300, with the filter assembly 200 located between the front panel 100 and the fan assembly 500.

[0049] A first oil guide 110 is provided on the end face of the front plate 100 near the filter assembly 200. An oil cup 400 is disposed inside the housing 300 and located below the first oil guide 110. Grease and water collected in the front plate 100 are collected in the oil cup 400 through the first oil guide 110.

[0050] Specific combination Figures 1 to 4As shown, during the use of the tabletop range hood, the fan assembly 500 starts, creating negative pressure at the air inlet of the front panel 100. Oil fumes and water vapor enter the tabletop range hood through the air inlet and are processed. Specifically: firstly, a portion of the oil fumes and water vapor are intercepted and condensed as they pass through the air inlet on the front panel 100. The condensed grease and water adhere to the end face of the front panel 100 near the filter assembly 200, and then flow under gravity, eventually being guided into the oil cup 400 through the first oil guide 110. Then, most of the grease and water vapor are intercepted by the filter assembly 200. The condensed grease and water adhere to the filter assembly 200 and flow under gravity, eventually flowing into the oil cup 400. Throughout the process, the filter component 200 intercepts and purifies the oil fumes and water vapor airflow; in addition, the filter component 200 works with the first oil guide component 110 to form multiple oil paths, which guide the condensed grease and water to prevent grease and water from flowing outside the oil cup 400, thereby improving the collection effect of grease and water and the performance of the tabletop range hood, and enhancing the user experience.

[0051] In the optional technical solution of this embodiment, a partition 310 is provided between the filter assembly 200 and the fan assembly 500. A second oil guide 311 is provided on the end face of the partition 310 near the filter assembly 200, and the oil cup 400 is located below the second oil guide 311.

[0052] Specific combination Figures 1 to 4 As shown, when the amount of oil fumes to be processed during the use of the tabletop range hood is too large, the filter assembly 200 cannot filter and intercept all the oil fumes. Therefore, a small amount of oil fumes may pass through the filter assembly 200 and reach the fan assembly 500. Since the baffle 310 separates the filter assembly 200 from the fan assembly 500, it can prevent oil fumes from reaching the fan assembly 500, further improving the performance and service life of the fan assembly 500. Moreover, when a small amount of oil fumes that are not intercepted by the filter assembly reach the baffle 310, they are condensed. The condensed grease and water adhere to the baffle 310 and flow downwards under gravity, finally being guided into the oil cup 400 by the second oil guide 311. The first oil guide 110 and the second oil guide 311 work together to further reduce the probability of grease and water flowing outside the oil cup 400.

[0053] In the optional technical solution of this embodiment, the first oil guide 110 and the second oil guide 311 extend in a long strip along the width direction of the tabletop range hood, and both the first oil guide 110 and the second oil guide 311 are inclined downward along the height direction of the tabletop range hood.

[0054] Specific combination Figures 1 to 4As shown, with this configuration, the first oil guide 110 can guide all the grease and water adhering to the front plate 100 into the oil cup 400, preventing grease and water from accumulating between the first oil guide 110 and the front plate 100; the second oil guide 311 guides all the grease and water adhering to the partition 310 into the oil cup 400, preventing grease and water from accumulating between the first oil guide 110 and the partition 310. This further improves the guiding effect and reduces the probability of grease and water flowing outside the oil cup 400.

[0055] In the optional technical solution of this embodiment, the partition 310 divides the interior of the housing 300 into a first receiving cavity 320 and a second receiving cavity 330 along the depth direction of the housing 300. The second receiving cavity 330 is disposed opposite to the front plate 100. The fan assembly 500 is fixedly disposed in the first receiving cavity 320, and the filter assembly 200 is disposed in the second receiving cavity 330.

[0056] Specific combination Figures 1 to 4 As shown, this configuration avoids interference between the fan assembly 500 and the filter assembly 200, and also prevents grease and water adhering to the filter assembly 200 from affecting the fan assembly 500, thereby ensuring the performance and user experience of the tabletop range hood.

[0057] In the optional technical solution of this embodiment, the tabletop range hood also includes an installation component 240, which is disposed in the second receiving cavity 330. The installation component 240 is provided with a filter cavity 241, and the rear wall of the filter cavity 241 is provided with an installation opening. The second oil guide component 311 extends into the filter cavity 241 through the installation opening.

[0058] The filter assembly 200 is disposed in the filter chamber 241, and the oil cup 400 is disposed below the filter chamber 241.

[0059] Specific combination Figures 1 to 4 As shown, a slot is provided on the end face of the partition 310 opposite to the first receiving cavity 320, and a buckle is provided on the rear wall of the mounting member 240. The mounting member 240 is installed on the partition 310 by engaging with the slot through the buckle. Since the mounting member 240 is provided with a filter screen cavity 241 and the rear wall of the filter screen cavity 241 is provided with an installation opening, when the mounting member 240 is installed on the partition 310, the installation opening of the second oil guide member 311 extends into the filter screen cavity 241. With this configuration, the grease and water adhering to the filter assembly 200 eventually drip onto the bottom wall 2410 of the filter chamber 241. The grease and water adhering to the partition 310 are guided by the second oil guide 311 and also eventually drip onto the bottom wall 2410 of the filter chamber 241. The grease and water collected on the bottom wall 2410 of the filter chamber eventually flow into the oil cup 400 located below the filter chamber 241, preventing grease and water from flowing outside the oil cup 400 and ensuring a good user experience.

[0060] In addition, besides the snap-fit ​​method mentioned above, the mounting component 240 can also be connected to the partition plate 310 by threaded fasteners, adhesive bonding, welding, etc.

[0061] In this embodiment, the bottom wall 2410 of the filter chamber 241 is inclined along the height direction of the tabletop range hood.

[0062] Specific combination Figures 1 to 4 As shown, with this configuration, when grease and water collect at the bottom wall 2410 of the filter chamber, due to the inclined design of the bottom wall 2410, the grease and water can flow into the oil cup 400 under the action of gravity, avoiding accumulation on the bottom wall 2410 of the filter chamber, thereby further improving the collection effect of grease and water and the performance of the tabletop range hood.

[0063] In the optional technical solution of this embodiment, the bottom wall 2410 of the filter chamber is inclined towards the bottom wall 340 of the housing 300 along the direction from the housing 300 to the front plate 100.

[0064] Specific combination Figures 1 to 4 As shown, the inclination direction of the bottom wall 2410 of the filter chamber can be set to be inclined towards the bottom wall 340 of the housing along the direction from the housing 300 to the front plate 100, or it can be set to be inclined away from the bottom wall 340 of the housing along the direction from the housing 300 to the front plate 100. The specific setting method is selected according to specific needs, and the technical effect of facilitating the flow of grease and water collected on the bottom wall 2410 of the filter chamber to the oil cup 400 and preventing grease and water from accumulating on the bottom wall 2410 of the filter chamber is acceptable. In this embodiment, the bottom wall 2410 of the filter chamber is inclined towards the bottom wall 340 of the housing along the direction from the housing 300 to the front plate 100.

[0065] In the optional technical solution of this embodiment, a first oil-blocking rib 2411 is provided on the side of the bottom wall 2410 of the filter chamber near the front plate 100, and a second oil-blocking rib 2412 is provided on the side of the bottom wall 2410 of the filter chamber near the partition 310, and the second oil-blocking rib 2412 abuts against the partition 310.

[0066] An oil leakage groove 2413 is provided on the bottom wall 2410 of the filter chamber, and the oil leakage groove 2413 is located near the first oil-blocking rib 2411.

[0067] Specific combination Figures 1 to 4As shown, the first oil-blocking rib 2411 and the second oil-blocking rib 2412 cooperate with the bottom wall 2410 of the filter chamber and the two side walls of the filter chamber 241 to form an oil collection groove. The second oil-blocking rib 2412 abuts against the partition plate 310, and the oil leakage groove 2413 is set near the first oil-blocking rib 2411 on the bottom wall 2410 of the filter chamber. With this arrangement, when the grease and water adhering to the filter assembly 200 and the partition plate 310 flow to the bottom wall 2410 of the filter chamber under the action of gravity, the oil collection groove can prevent the grease and water from flowing outside the bottom wall 2410 of the filter chamber, thereby preventing the grease and water from flowing outside the oil cup 400. The oil leakage groove 2413 is set on the bottom wall 2410 of the filter chamber so that the grease and water collected in the oil collection groove can flow into the oil cup 400 through the oil leakage groove 2413, preventing the grease and water from overflowing from the oil collection groove.

[0068] In the optional technical solution of this embodiment, a guide member 2414 is provided on the end face of the bottom wall 2410 of the filter screen cavity away from the filter screen cavity 241, and the guide member 2414 surrounds the outer periphery of the oil leakage groove 2413.

[0069] Specific combination Figure 4 As shown, the guide member 2414 is cylindrical, with one end fixedly connected to the end face of the bottom wall 2410 of the filter chamber away from the filter chamber 241, and the other end extending towards the oil cup 400 and surrounding the outer periphery of the oil drain groove 2413. With this configuration, when grease and water collected on the bottom wall 2410 of the filter chamber flow through the oil drain groove 2413 to the oil cup 400, the guide member 2414 can prevent the grease and water from spreading on the end face of the bottom wall 2410 away from the filter chamber 241, thereby preventing grease and water from flowing outside the oil cup 400 and further improving the user experience.

[0070] In the optional technical solution of this embodiment, the filter assembly 200 includes a pre-filter 210, a primary filter 220 and a main filter 230. The pre-filter 210 is disposed on the front panel 100 corresponding to the air inlet on the front panel 100. The primary filter 220 and the main filter 230 are both disposed in the filter cavity 241. The primary filter 220 is disposed close to the front panel 100, and the main filter 230 is disposed between the primary filter 220 and the partition 310.

[0071] Specific combination Figures 1 to 6As shown, with this configuration, during the use of the tabletop range hood, the oil fumes and water vapor are successively intercepted and purified by the pre-filter 210, the primary filter 220, and the main filter 230 before being discharged from the top air outlet of the entire unit. Specifically, large grease particles are first intercepted and condensed by the pre-filter 210, then flow under gravity and are guided into the oil cup 400 by the first oil guide 110; most of the grease and water vapor are intercepted by the primary filter 220 and the main filter 230, and the condensed grease and water flow under gravity, eventually flowing into the oil cup 400 through the oil drain trough 2413; a small amount of water vapor that is not intercepted by the primary filter 220 and the main filter 230 is condensed at the baffle 310, flows to the bottom wall 2410 of the filter chamber through the second oil guide 311, and is then guided into the oil cup 400 through the oil drain trough 2413. Throughout the process, the pre-filter 210, primary filter 220, and main filter 230 work together to form a complete filtration and purification system, comprehensively intercepting and purifying oil fumes and water vapor. Furthermore, the pre-filter 210, primary filter 220, and main filter 230, in conjunction with the first oil guide 110, the second oil guide 311, and the bottom wall 2410 of the filter chamber, form multiple oil paths to guide the condensed grease and water, preventing them from flowing outside the oil cup 400, thereby improving the user experience. In this embodiment, the primary filter 220 is a static cotton mesh covered with a mesh, and the main filter 230 is a HEPA dual-effect filter. The filter is made of dual-effect filter material through folding, gluing, and edge sealing.

[0072] In addition, in this embodiment, the primary filter element 220 is attached to the filter chamber 241 by a hook, and the hook is detachably set in the filter chamber 241. With this setting, when the primary filter element 220 is damaged, the damaged primary filter element 220 can be removed and a new primary filter element 220 can be attached to the hook to complete the replacement. The operation is convenient, and there is no need to replace the entire filter assembly 200 and the mounting part 240, saving maintenance costs.

[0073] In the optional technical solution of this embodiment, the distance from the first bottom wall 221 of the primary filter element 220 to the top wall of the filter cavity 241 is less than the distance from the second bottom wall 233 of the main filter element 230 to the top wall of the filter cavity 241.

[0074] Specific combination Figure 3 , Figure 4 and Figure 6 and Figure 7As shown, when the distance from the first bottom wall 221 to the top wall of the filter cavity 241 is greater than or equal to the distance from the second bottom wall 233 to the top wall of the filter cavity 241, grease and water collected in the main filter element 230 may be blocked by the primary filter element 220, preventing the grease and water on the main filter from flowing out. Therefore, in this embodiment, the distance from the first bottom wall 221 to the top wall of the filter cavity 241 is set to be less than the distance from the second bottom wall 233 to the top wall of the filter cavity 241. This setting avoids the primary filter element 220 from affecting the main filter element 230 while ensuring the respective performance of the primary filter element 220 and the main filter element 230, thereby further improving the grease and water collection effect and the performance of the tabletop range hood.

[0075] In the optional technical solution of this embodiment, the main filter element 230 includes a frame 231 and a plurality of pleats 232. The plurality of pleats 232 are spaced apart on the frame 231 along the width direction of the frame 231 and all extend along the height direction of the tabletop range hood. The second bottom wall 233 is inclined to correspond to the bottom wall 2410 of the filter cavity.

[0076] Specific combination Figure 2 , Figure 4 and Figure 5 As shown, multiple pleats 232 are evenly spaced and fixedly arranged in the frame 231 along the width direction of the second bottom wall 233, and all extend along the height direction of the frame 231. Grease and water intercepted by the main filter element 230 adhere to the multiple pleats 232 and flow downwards along them under gravity, eventually collecting at the bottom wall 2410 of the filter chamber for further processing. This arrangement ensures consistent filtration efficiency throughout the main filter element 230 and prevents grease and water from accumulating on the multiple pleats 232. Inclining the second bottom wall 233 relative to the bottom wall 2410 of the filter chamber further prevents grease and water accumulating on the sides from accumulating on the sides of the frame 231, thus improving the collection efficiency.

[0077] In the optional technical solutions of this embodiment, α=β, and / or, 13°≤α≤20°, and / or, 13°≤β≤20°, and / or, 5mm≤L≤10mm;

[0078] α is the tilt angle of the side of the frame 231, β is the tilt angle of the bottom wall 2410 of the filter cavity, and L is the difference between the distance from the first bottom wall 221 to the top wall of the filter cavity 241 and the distance from the second bottom wall 233 to the top wall of the filter cavity 241.

[0079] Specific combination Figures 4 to 7As shown, when the inclination angle β of the bottom wall 2410 of the filter cavity is set to 0°, the bottom wall 2410 of the filter cavity is parallel to the horizontal plane. During the process of the grease and water collected on the bottom wall 2410 flowing from the oil drain 2413 to the oil cup 400, some grease and water may remain on the bottom wall 2410, thus affecting the collection effect and the performance of the tabletop range hood. Therefore, β is set to 13°-20°. Since the side of the frame 231 abuts against the bottom wall 2410 of the filter cavity, to prevent grease and water from remaining on the side of the frame 231, the inclination angle α of the side of the frame 231 is set to 13°-20° corresponding to β. This setting ensures that the grease and water collected on the side of the frame 231 and the bottom wall 2410 of the filter cavity can flow into the oil cup 400 under gravity, thus ensuring the collection effect and the performance of the tabletop range hood. In addition, to prevent grease and water from accumulating between the bottom wall 2410 of the filter chamber and the side of the frame 231, in this embodiment, the tilt angle β of the bottom wall 2410 of the filter chamber is set to be equal to the tilt angle α of the side of the frame 231, and both are set to 14°, that is, α=β=14°.

[0080] When the distance from the first bottom wall 221 to the top wall of the filter cavity 241 is greater than or equal to the distance from the second bottom wall 233 to the top wall of the filter cavity 241, grease and water collected in the main filter element 230 may be blocked by the primary filter element 220, preventing the grease and water on the main filter from flowing out. Therefore, in this embodiment, the distance from the first bottom wall 221 to the top wall of the filter cavity 241 is set to be less than the distance from the second bottom wall 233 to the top wall of the filter cavity 241, and the difference L is set to 5mm-10mm. This avoids the primary filter element 220 from affecting the main filter element 230 while ensuring the respective performance of the primary filter element 220 and the main filter element 230, thereby further improving the grease and water collection effect and the performance of the tabletop range hood. In this embodiment, L can be set to 8mm.

[0081] In the optional technical solution of this embodiment, a limiting member 2415 is provided on the end face of the bottom wall 2410 of the filter cavity near the filter cavity 241. The limiting member 2415 is located between the first oil-blocking rib 2411 and the frame 231.

[0082] Specific combination Figures 1 to 4As shown, the number of limiting members 2415 can be appropriately increased or decreased according to specific needs, achieving the technical objective of limiting the relative position of the main filter element 230, preventing the main filter element 230 from moving forward and blocking the oil leakage groove 2413, thereby ensuring the oil collection effect. In this embodiment, two limiting members 2415 are provided between the first oil-blocking rib 2411 and the frame 231. The two limiting members 2415 are respectively located close to the two side walls of the filter screen cavity 241, and the oil leakage groove 2413 is located between the two limiting members 2415. This arrangement prevents the main filter element 230 from moving forward and blocking the oil leakage groove 2413, affecting the oil collection effect, and ensures that the water and grease collected on the bottom wall 2410 of the filter screen cavity flow smoothly from the oil leakage groove 2413 to the oil cup 400.

[0083] In the optional technical solution of this embodiment, the tabletop range hood also includes a protective grille 600, which is disposed on the partition 310 corresponding to the filter assembly 200, and a condenser is disposed on the protective grille 600.

[0084] Specific combination Figure 1 and Figure 2 As shown, an air inlet is provided on the partition 310 corresponding to the fan assembly 500. A protective grille 600 is provided at the air inlet, and a condenser is provided on the side of the protective grille 600 facing away from the fan assembly 500. The protective grille 600 provides a certain degree of protection, preventing accidental injury due to the start-up of the fan assembly 500 after the initial filter 220 and main filter 230 are removed. The condenser has a condensing effect on the water vapor passing through the air inlet. The condensed water is guided to the bottom wall 2410 of the filter chamber through the second oil guide 311, and finally enters the oil cup 400 through the oil drain trough 2413 for treatment. The condenser can be made of a material with condensing effect. In this embodiment, the condenser is an aluminum foil sheet.
