Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification for household range hoods, in particular to a no-cleaning range hood. Background Art

[0002] As people's living standards improve, more and more attention is paid to the cleanliness of the kitchen environment. Although traditional range hoods can absorb most of the fumes during cooking, they still have some limitations:

[0003] High cleaning frequency: After a period of use, a large amount of grease will accumulate inside the traditional range hood, which requires regular cleaning. This is not only time-consuming and labor-intensive, but may also affect the service life and performance of the range hood due to improper cleaning.

[0004] High maintenance cost: The cleaning and maintenance of the range hood need to be performed by professionals, which not only increases the financial burden on the family, but also increases the time cost.

[0005] Environmental pollution: The oil smoke sucked in by the range hood is discharged directly to the outdoors, which will cause certain air pollution.

[0006] Therefore, further optimization design is needed. Utility Model Content

[0007] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art and provide a range hood that does not require cleaning, so that the oil smoke can be decomposed and completely purified inside the range hood, thus avoiding the accumulation of grease inside the range hood and achieving the effect of no need for cleaning and exhausting oil smoke-free.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0009] A no-clean range hood includes a housing, an air intake grille, a high-voltage discharge plate, and a composite ultraviolet wave tube. The air intake grille is positioned at the housing's air inlet, and the high-voltage discharge plate is positioned behind the air passage of the air intake grille. The composite ultraviolet wave tube is positioned behind the air passage of the high-voltage discharge plate. Oil fume particles in the oil fume drawn into the housing first pass through the air intake grille. The high-voltage electric shock from the high-voltage discharge plate breaks down large particles into tiny ones, while the majority of the oil fume particles are rapidly degraded and carbonized. The remaining small particles are then irradiated by ultraviolet light from the composite ultraviolet wave tube. Ultraviolet light has powerful bactericidal and decomposing capabilities, further breaking down oil molecules while simultaneously killing bacteria and mold that may grow, thereby maintaining a clean and hygienic interior of the range hood.

[0010] Preferably, the high-voltage discharge plate is an 8KV discharge plate. By setting up an 8KV high-voltage discharge plate, large particles of oil smoke can be quickly decomposed and most of them can be carbonized.

[0011] Preferably, the high-voltage discharge plate is a multi-layer structure to enhance the decomposition effect of high-voltage electric shock.

[0012] Preferably, a safety switch for the high-voltage discharge plate is provided at the installation location of the air intake grille. When the air intake grille is removed, the safety switch of the high-voltage discharge plate is activated to disconnect the high-voltage discharge plate, thereby preventing the user from being injured by accidentally touching the high-voltage discharge plate when removing the air intake grille due to forgetting to disconnect the power.

[0013] Preferably, the composite ultraviolet wave tube comprises a plurality of ultraviolet lamps to enhance the decomposition effect of ultraviolet rays on tiny particles of oil smoke.

[0014] Preferably, the composite UV light tube includes UV lamps emitting wavelengths of 185nm and 275nm, capable of generating ozone. Ozone has a strong oxidizing effect on organic matter and is highly effective in removing cooking fumes and their odors. The emission of 185nm photons increases the efficiency by approximately 90% at the same power consumption, resulting in a service life of up to 10,000 hours. For kitchen fume purification, it offers high oil removal efficiency, excellent odor removal, and prevents oil accumulation on the interior walls.

[0015] Preferably, a safety switch for the composite UV light tube is provided at the installation position of the air intake grille. When the air intake grille is removed, the safety switch of the composite UV light tube is activated to cut off the power supply to the composite UV light tube, thereby preventing the user from forgetting to cut off the power supply and being injured by ultraviolet rays when removing the air intake grille.

[0016] Preferably, aluminum-based oil-isolating nets are provided on both sides of the composite ultraviolet wave tube.

[0017] Preferably, an oil collecting box is provided below the air intake grille, and the oil stains on the outer surface of the air intake grille flow into the oil collecting box under the action of gravity and can be cleaned regularly.

[0018] Preferably, the high-voltage discharge plate is a bipolar discharge plate, comprising a positive plate, a double-layer ground plate and a bipolar discharge head arranged on the positive plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The utility model arranges a high-voltage discharge plate and a composite ultraviolet wave tube in the casing, so that the oil smoke is decomposed and completely purified in the range hood, avoiding the accumulation of grease inside the range hood, and achieving the effect of no need to clean the inside of the casing and exhausting gas without oil smoke.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 3As shown, a no-clean range hood includes a housing 1, an air intake grille 2, a high-voltage discharge plate 3, and a composite UV wave tube 4. The air intake grille 2 is positioned at the air inlet of the housing 1. The high-voltage discharge plate 3 is positioned behind the air passage of the air intake grille 2. The composite UV wave tube 4 is positioned behind the air passage of the high-voltage discharge plate 3. Oil fume particles drawn into the housing first pass through the air intake grille 2. The high-voltage electric shock of the high-voltage discharge plate 3 breaks down large particles into tiny ones, rapidly degrading and carbonizing most of the oil fume particles. The remaining small particles are then irradiated by ultraviolet light from the composite UV wave tube 4. Ultraviolet light has powerful bactericidal and decomposing properties, further breaking down oil molecules while simultaneously killing any bacteria and mold that may grow, thereby maintaining a clean and hygienic interior of the range hood. The high-voltage discharge plate 3 is an 8kV discharge plate. By providing an 8kV high-voltage discharge plate 3, large oil fume particles can be quickly decomposed and a large portion of them carbonized. The high-voltage discharge plate 3 features a multi-layer structure to enhance the effectiveness of high-voltage electric shock dissipation. A safety switch for the high-voltage discharge plate 3 is located at the mounting location of the air intake grille 2. When the air intake grille 2 is removed, the safety switch activates, disconnecting the high-voltage discharge plate 3. This prevents injuries from the user accidentally touching the high-voltage discharge plate 3 while removing the air intake grille 2 due to forgetting to disconnect the power.

[0030] like Figure 2 As shown, the composite UV light tube 4 includes multiple UV lamps to enhance the UV light's effectiveness in decomposing fine oil fume particles. The composite UV light tube 4 includes UV lamps emitting wavelengths of 185nm and 275nm, which generate ozone. Ozone has a strong oxidizing effect on organic matter and is highly effective in removing oil fumes and their odors. The power of the emitted 185nm photons is increased by approximately 90% at the same power consumption, resulting in a service life of up to 10,000 hours. For kitchen fume purification, it features high oil removal efficiency, excellent odor removal, and prevents oil accumulation on the interior walls. A safety switch for the composite UV light tube 4 is installed at the mounting location of the air intake grille 2. When the air intake grille 2 is removed, the safety switch activates, shutting off the power to the composite UV light tube 4. This prevents users from forgetting to turn off the power and being exposed to UV rays when removing the air intake grille 2. Aluminum-based oil screens are installed on both sides of the composite UV light tube 4 to enhance the UV light's effectiveness in decomposing fine oil fume particles, ensuring complete removal.

[0031] An oil collecting box is provided below the air intake grille 2. The oil on the outer surface of the air intake grille 2 flows into the oil collecting box under the action of gravity and can be cleaned regularly.

[0032] like Figure 4 As shown, the high-voltage discharge plate 3 is a bipolar discharge plate, comprising a positive plate 3-1, a double-layer ground plate 3-2 and a bipolar discharge head 3-3 arranged on the positive plate 3-1.

[0033] The utility model disposes a high-voltage discharge plate 3 and a composite ultraviolet wave tube 4 in the casing 1, so that the oil smoke is decomposed and completely purified in the range hood, avoiding the accumulation of grease inside the range hood, and achieving the effect of no need to clean the inside of the casing 1 and exhausting gas without oil smoke.
