Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a stainless steel UV fume hood. Background Technology

[0002] Traditional commercial kitchen fume hoods generally use mechanical filters to intercept grease, which has drawbacks such as low purification efficiency, rapid grease buildup, and incomplete odor removal. Grease adheres to the surface of the metal filter, easily forming stubborn grease deposits. Frequent disassembly and cleaning not only increases labor costs but also easily leads to filter deformation and failure. At the same time, volatile organic compounds (such as aldehydes and ketones) and microbial aerosols generated by low- and medium-temperature cooking are difficult to physically intercept, resulting in unpleasant odors from exhaust ventilation and environmental pollution. Although some equipment has introduced ultraviolet purification technology, the complex fixing method of UV lamps (requiring the removal of bolts or the entire module) and the lack of a synergistic mechanism between multi-stage physical interception and photochemical oxidation make system maintenance difficult and purification efficiency unstable.

[0003] Therefore, a stainless steel UV fume hood is being developed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, this utility model provides a stainless steel UV fume hood.

[0005] The technical solution of this utility model is:

[0006] A stainless steel UV fume hood includes a fume hood with a limiting groove on the rear side inside. A filter plate is slidably connected to the lower part of the fume hood, and an oil collection frame is slidably provided in the lower part of the fume hood. Locking components are rotatably provided on both the left and right sides of the fume hood, and the locking components are used to lock and limit the oil collection frame. A mounting bracket is slidably connected to the upper part of the fume hood, and the rear side of the mounting bracket contacts the limiting groove. A UV lamp tube is snapped onto the mounting bracket, and the UV lamp tube can be disassembled by pushing it backward to detach it from the mounting bracket.

[0007] In one embodiment, the oil collecting frame has assist grooves on both the left and right sides.

[0008] In one embodiment, the oil collecting frame has inclined structures on both the left and right sides.

[0009] In one embodiment, the top of the fume hood has a reserved opening, and the reserved opening has a mounting hole.

[0010] In one embodiment, the mounting bracket is provided with a limiting plate, which is used to guide and limit the UV lamp tube.

[0011] In one embodiment, the front side of the fume hood is rotatably connected with four blocking members, which are used to limit and block the mounting bracket and the filter plate respectively.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a sliding filter plate to efficiently intercept large grease particles, significantly reducing the load on subsequent processing units. The quickly detachable UV lamps, aided by a snap-fit ​​limiting structure, stimulate deep ultraviolet photolysis, working in conjunction with ozone oxidation to thoroughly decompose odor molecules and organic pollutants while efficiently inactivating microorganisms. The one-piece molded stainless steel structure combines excellent mechanical strength and corrosion resistance, ensuring continuous and stable operation of the equipment in harsh kitchen environments.

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] A stainless steel UV fume hood, such as Figures 1-5As shown, the device includes a smoke hood 1, a limiting groove 11 on the rear side of the smoke hood 1, a filter plate 2 slidably connected to the lower part of the smoke hood 1, an oil collection frame 3 slidably connected to the lower part of the smoke hood 1, assisting grooves on both the left and right sides of the oil collection frame 3, inclined structures 31 on both the left and right sides of the oil collection frame 3, locking parts 4 rotatably connected to both the left and right sides of the smoke hood 1, the locking parts 4 are used to lock and limit the oil collection frame 3, a reserved opening 5 is opened at the top of the smoke hood 1, the reserved opening 5 has a mounting hole, a mounting bracket 6 slidably connected to the upper part of the smoke hood 1, the rear side of the mounting bracket 6 contacts the limiting groove 11, a UV lamp tube 7 is snapped onto the mounting bracket 6, a limiting plate 8 is provided on the mounting bracket 6, the limiting plate 8 is used to guide and limit the UV lamp tube 7, the UV lamp tube 7 can be disassembled by pushing it backward to detach from the mounting bracket 6, and four blocking parts are rotatably connected to the front side of the smoke hood 1, which are used to limit and block the mounting bracket 6 and the filter plate 2 respectively.

[0022] It should be noted that the cooking fumes are forcefully drawn into the air inlet of the fume hood 1 under the negative pressure of the fan. At this time, the filter plate 2, which is slidably installed at the bottom of the fume hood 1, immediately plays a primary interception role. Its precision-woven metal mesh or special composite filter material can efficiently capture most of the large oil particles, solid food residues, and some suspended matter, significantly reducing the load on subsequent processing units and extending the overall maintenance cycle of the equipment. The airflow that has passed the initial filtration continues to flow upward and contacts the core purification unit. The mounting bracket 6 ensures the absolute stability of the structure through the precise fitting of its rear side with the rear limiting groove 11 inside the fume hood 1 and the effective locking of the four blocking parts on the front side. The specific wavelength high-intensity UV lamp tube 7 (usually in the range of 185 nm to 254 nm) clipped on the mounting bracket 6 is stably lit. Its front and rear ends are precisely guided and constrained by the limiting plates 8 on the mounting bracket 6. The ultraviolet irradiation has a dual purification effect:

[0023] On the one hand, short-wave ultraviolet light can directly destroy the DNA / RNA structure of bacteria, viruses, and other microorganisms when it penetrates the cooking fumes, effectively inactivating pathogens. On the other hand, ultraviolet light of specific wavelengths can excite oxygen molecules in the air, causing them to generate ozone, which has a strong oxidizing ability. Freshly generated ozone can quickly undergo a deep chain oxidation reaction with residual organic compounds (such as fatty acids, aldehydes, ketones, and other gaseous pollutants) and stubborn odor molecules, gradually degrading them into harmless carbon dioxide, water molecules, or other low-molecular-weight stable compounds, thus achieving fundamental removal of odors rather than simply masking them. The carefully designed inclined structure 31 on both sides of the oil collection frame 3, which is slidably installed in the lower part of the fume hood 1, is crucial.

[0024] Liquid grease that has been captured but not completely degraded, oil mist droplets that have been cracked by ultraviolet radiation and then re-condensed, and some particles that have not been completely oxidized, when the airflow passes above the oil collection frame 3, their kinetic energy is suddenly reduced due to the collision with the inclined surface. Under the combined action of surface tension and gravity, these oil droplets slide smoothly down the inclined surface and eventually converge at the bottom of the oil collection frame 3 to form a liquid oil film, achieving efficient centralized recycling. At the same time, after the oil collection frame 3 is fully pushed into place, the locking part 4 is manually rotated to form a mechanical locking state, ensuring the stability of the oil collection frame 3 during equipment operation and preventing accidental displacement caused by vibration or airflow impact. During cleaning, the operator only needs to first remove the obstruction part in the area corresponding to the mounting bracket 6 on the front side of the fume hood 1 to release the front limit of the mounting bracket 6, and then smoothly pull out the mounting bracket 6 and the UV lamp tube 7 integrated on it along the slide rail for routine cleaning of the accumulated dust.

[0025] If the lamp tube needs to be replaced, there is no need to disassemble the entire mounting bracket 6. Simply push the rear of the UV lamp tube 7 backward in the specific direction designed by the limiting plate 8, so that it slides backward and is freed from the front end buckle constraint. The old lamp tube can be easily removed. The new lamp tube is pushed in the opposite direction along the track of the limiting plate 8 until a click is heard. This design greatly improves the replacement efficiency of key consumables. For the maintenance of the oil collection frame 3, manually unscrew the locking parts 4 on the left and right sides to release it from the assist groove. The operator can use both hands to insert into the assist groove to provide a stable force point, and completely pull out the oil collection frame 3 filled with waste oil along the slide rail to clean and wipe it. The reserved opening 5 and matching mounting holes on the top of the fume hood 1 provide standardized connection points for external exhaust ducts or fan units, ensuring the smooth exhaust of the system.
