Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a range hood and a range hood. Background Art

[0002] Existing range hoods are equipped with a filter layer to filter and intercept harmful particles in the smoke. For example, porous filters (such as metal mesh covers, grilles, etc.) are used to intercept particles in the smoke. When the smoke passes through these filters, larger particles will collide with the filter surface under the action of inertia and be intercepted. However, this filter has a low efficiency in intercepting harmful particles, resulting in a large amount of harmful particles still being discharged after the smoke passes through the filter, affecting environmental health. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model proposes a fume micro-buffer structure, which can improve the interception efficiency of harmful particulate matter.

[0004] The technical solution of the utility model is achieved in this way:

[0005] A fume micro-buffer structure comprises a filter layer and a buffer layer. The buffer layer is arranged on the upper side and / or lower side of the filter layer. The surface and interior of the buffer layer are covered with small holes. The small holes are interconnected to form a channel for the fume to pass through.

[0006] Preferably, the small holes are arranged irregularly.

[0007] Preferably, the sizes of the small holes are different.

[0008] Preferably, the shape of the small hole is one or more of circular, quasi-circular, and irregular.

[0009] Preferably, the buffer layer is made of molecular sieve material and / or activated carbon.

[0010] Preferably, the inner wall of the small hole is coated with a photocatalyst material.

[0011] Preferably, the buffer layer has a plate-like or wavy shape.

[0012] A range hood comprises a fume duct, in which at least one fume micro-buffer structure is arranged.

[0013] Preferably, the oil fume micro-buffer structure is arranged obliquely in the oil fume channel.

[0014] Preferably, the oil fume micro-buffer structure is detachably arranged in the oil fume passage.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the oil fume micro-buffering structure includes a filter layer and a buffer layer, the buffer layer is arranged on the upper side and / or the lower side of the filter layer, the surface and the interior of the buffer layer are covered with small holes, and the small holes are interconnected to form a channel for oil fume to pass through. When the oil fume passes through the buffer layer of the oil fume micro-buffering structure, the small holes of the buffer layer can increase the collision between the harmful particles and the body, and the number of collisions is greater than that of ordinary pore filters, which plays a micro-buffering effect, thereby being able to temporarily intercept the oil fume, so that the oil fume can fully flow in the channel formed between the small holes, and the harmful particles are trapped in the small holes, thereby improving the interception efficiency of the harmful particles.

[0023] Embodiment 1

[0024] See also Figure 1 This embodiment provides a fume micro-buffering structure 1, a filter layer 11 and a buffer layer 12, wherein the buffer layer 12 is arranged on the lower side of the filter layer 11, and the surface and interior of the buffer layer 12 are covered with small holes 121, and the small holes 121 are interconnected to form a channel for the fume to pass through. When the fume passes through the fume micro-buffering structure 1, the fume first enters the buffer layer 12, and the small holes of the buffer layer 12 can increase the collision between the harmful particles and the buffer layer 12, and the number of collisions is greater than that with ordinary pore filters, which plays a micro-buffering effect, thereby being able to temporarily intercept the fume, so that the fume can fully flow in the channel formed between the small holes 121, and the harmful particles are trapped in the small holes 121, thereby improving the interception efficiency of the harmful particles, and then the fume enters the filter layer 11, and the filter layer 11 further filters the fume, thereby improving the fume purification effect through the fume micro-buffering structure 1.

[0025] The habitual flow of oil smoke will cause the oil smoke to escape or be incompletely adsorbed, and may increase the workload of the range hood, resulting in increased energy consumption. In this embodiment, the small holes 121 are irregularly arranged. The irregularly arranged small holes 121 are conducive to increasing the disorder of the oil smoke when it passes through, and can avoid the formation of a habitual oil smoke flow direction, increase the number of collisions of harmful particles, and thus further improve the interception efficiency of harmful particles. The surface and interior of the buffer layer 12 are covered with small holes 121. The small holes 121 are irregularly arranged to form a porous structure like an ant nest, which is conducive to increasing the number of collisions of harmful particles in the buffer layer 12, improving the buffering effect of the oil smoke micro-buffer structure 1, so that harmful particles can be effectively intercepted.

[0026] Preferably, the small holes 121 have different sizes. The small holes 121 of different sizes can also increase the turbulence of the oil smoke when it passes through, and can avoid forming a habitual oil smoke flow direction, increase the number of collisions of harmful particles, and thus can further improve the interception efficiency of harmful particles.

[0027] Among them, the shape of the small hole 121 is one or more of circular, quasi-circular, and irregular. When using multiple hole types, the flow disorder of the oil fume can be increased, thereby improving the interception effect of the oil fume micro-buffer structure 1 on harmful particles. Among them, the irregularly designed small hole 121 can improve the flow state of the oil fume, and thus can provide better interception performance. Reasonable hole design can reduce the blockage and wear of the small hole 121, reduce the frequency of maintenance and replacement, and thus reduce the cost of use. Therefore, the arrangement of multiple hole types can be designed according to needs.

[0028] The filter layer 11 is an activated carbon cotton filter, an activated carbon filter, a glass fiber filter or a mesh plate coated with a photocatalyst, which is used to purify oil smoke.

[0029] Preferably, the buffer layer 12 is made of molecular sieve material and / or activated carbon, so that harmful particles in the oil fume can be adsorbed by the molecular sieve material and / or activated carbon when passing through the channel formed by the small holes 121, ensuring the filtering and interception effect of the oil fume micro-buffer structure 1.

[0030] Preferably, the inner wall of the small hole 121 is coated with a photocatalyst material. When illuminated, the photocatalytic reaction of the photocatalyst can produce hydroxyl free radicals and release negative ions. These substances have strong oxidizing properties and can effectively decompose bacteria, viruses and the endotoxins produced after their death. At the same time, they can decompose the malodorous gases produced by organic matter, such as ammonia, hydrogen sulfide, etc., to achieve the effects of air purification, sterilization and deodorization.

[0031] In the present embodiment, the shape of the buffer layer 12 is plate-shaped, and the molding is simpler. In other embodiments, the shape of the buffer layer 12 is wavy. The wavy buffer layer 12 increases the surface area of ​​the buffer layer 12, thereby increasing the area of ​​filtration and interception, so that the oil smoke has more opportunities to contact with the oil smoke micro-buffer structure 1 when passing through the oil smoke micro-buffer structure 1, thereby improving the efficiency of filtration and interception. At the same time, when the oil smoke passes through the wavy buffer layer 12, its flow direction will change multiple times. This change helps to make more harmful particles in the oil smoke contact with the buffer layer 12 and be effectively intercepted, thereby improving the interception efficiency of harmful particles. In addition, the wavy design helps to optimize the flow path of the oil smoke when entering the buffer layer 12, reduce the flow resistance, and allow the oil smoke to enter the small holes 121 of the buffer layer 12 more smoothly.

[0032] Preferably, the buffer layer 12 and the filter layer 11 are fitted together. When the buffer layer 12 is plate-shaped, the filter layer 11 is also plate-shaped, which facilitates the fitting between the buffer layer 12 and the filter layer 11. When the buffer layer 12 is wavy in shape, the side of the filter layer 11 in contact with the buffer layer 12 is preferably wavy, which can better fit the buffer layer 12.

[0033] Embodiment 2

[0034] See also Figure 2 This embodiment provides an oil fume micro-buffering structure 1, a filter layer 11 and a buffer layer 12, wherein the buffer layer 12 is arranged on the upper side of the filter layer 11, and the surface and interior of the buffer layer 12 are covered with small holes 121, and the small holes 121 are interconnected to form a channel for the oil fume to pass through. When the oil fume passes through the oil fume micro-buffering structure 1, the oil fume first enters the filter layer 11, and the filter layer 11 filters the oil fume, and the oil fume discharged from the filter layer 11 enters the buffer layer 12. The small holes of the buffer layer 12 can increase the collision between the harmful particles and the buffer layer 12, and the number of collisions is greater than that with ordinary pore filters, which plays a micro-buffering effect, thereby being able to temporarily intercept the oil fume, so that the oil fume can fully flow in the channel formed between the small holes 121, and the harmful particles are trapped in the small holes 121, thereby improving the interception efficiency of the harmful particles.

[0035] In other embodiments, the buffer layer 12 can be simultaneously arranged on the upper and lower sides of the filter layer 11, that is, the oil fume micro-buffer structure 1 has a three-layer structure, from bottom to top are the buffer layer 12, the filter layer 11 and the buffer layer 12. The setting of the two buffer layers 12 is beneficial to further enhance the retention effect of harmful particulate matter.

[0036] Embodiment 3

[0037] See also Figure 3 This embodiment provides a range hood, comprising a fume duct 2, in which at least one fume micro-buffer structure 1 as described in the first embodiment is arranged. Figure 2 The oil fume channel 2 of the range hood is provided with three oil fume micro-buffer structures 1. The setting of multiple oil fume micro-buffer structures 1 can effectively improve the interception effect of the range hood on harmful particles, ensuring that fewer harmful particles are removed to avoid polluting environmental health.

[0038] In this embodiment, the oil fume micro-buffer structure 1 is horizontally arranged in the oil fume channel 2. The horizontally placed oil fume micro-buffer structure 1 can ensure that the oil fume is evenly distributed on the entire oil fume micro-buffer structure 1, avoiding the problem of excessive or insufficient local filtering load caused by uneven distribution of oil fume, and helping to improve the overall interception efficiency. In addition, the horizontally placed oil fume micro-buffer structure 1 is more stable in structure and is not easily displaced or deformed due to the impact of oil fume, which helps to maintain the overall structural stability of the oil fume micro-buffer structure 1.

[0039] In other embodiments, the oil fume micro-buffer structure 1 is tilted in the oil fume channel 2. The tilted oil fume micro-buffer structure 1 is conducive to guiding grease or water to the lower end of the oil fume micro-buffer structure 1, and then flows out along the inner wall of the oil fume channel 2, which is conducive to shortening the retention time of grease or water in the small hole 121.

[0040] Preferably, the oil fume micro-buffer structure 1 is detachably arranged in the oil fume channel 2, so as to facilitate regular removal and replacement of the oil fume micro-buffer structure 1 and to more conveniently adjust the oil fume micro-buffer structure 1 during installation, thereby avoiding the troublesome disassembly when installation errors occur.

[0041] During actual use, the range hood equipped with the oil fume micro-buffer structure 1 needs to regularly replace the oil fume micro-buffer structure 1, with a replacement frequency of once every 5 to 6 months. It does not need to be cleaned and has low maintenance difficulty, while an ordinary porous filter needs to be cleaned once every 2 to 3 months and has high maintenance difficulty.

[0042] When the oil fume micro-buffer structure 1 in the oil fume channel 2 contains a photocatalyst material, a light source should also be provided in the oil fume channel 2 so that the photocatalyst can undergo a photocatalytic reaction.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
