Description

Technical Field

[0001] This invention belongs to the technical field of smoke purification equipment, specifically relating to a photolysis component, a purification module, and a range hood. Background Technology

[0002] Cooking fumes refer to the smoky mixture produced during food cooking and processing, consisting of volatile organic compounds and condensates from cooking oil and food at high temperatures, aerosols, water vapor, and fine particulate matter. Current range hoods only function to remove these fumes; directly releasing them into the outside air causes environmental pollution and is not environmentally friendly. Based on the formation process and composition analysis of cooking fumes, it is determined that they are a complex aerosol composed of gas, liquid, and solid phases, varying depending on cooking conditions and the type of food.

[0003] Therefore, cooking fumes must undergo powerful purification before being released into the atmosphere to reduce pollution. The primary targets are grease particles, solid particulate matter, and gaseous pollutants. Due to the high-heat stir-frying characteristic of Chinese cooking, a large amount of fumes is produced, placing higher demands on the purification devices of range hoods, requiring them to have a longer lifespan.

[0004] Currently, range hoods typically have an air inlet at the bottom of their purification module. The fumes enter the module through this inlet and flow upwards, passing through the atomizing and condensing components to liquefy the fumes and form oil stains, thus preventing them from being released into the atmosphere. However, once the fumes enter the purification module, their flow path through the atomizing and condensing components is vertically upwards, resulting in a short flow path. The atomizing and condensing components cannot completely liquefy the fumes, causing the fumes discharged into the atmosphere to still contain a large amount of harmful substances that cannot be purified and removed by the atomizing and condensing components, ultimately polluting the environment.

[0025] Example 1: like Figure 1 and 4 As shown, this embodiment provides a photolysis component 100, which is installed in the photolysis chamber 220 of the purification module 10. The photolysis component 100 includes a mounting base 110, a UV lamp 114, and a catalyst bag 115. The mounting base 110 is located in the photolysis chamber 220. The mounting base 110 has a mounting cavity 111 and a catalyst cavity 112 arranged around the mounting cavity 111. A plurality of release holes 113 are provided around the mounting base 110. The UV lamp 114 is installed in the mounting cavity 111. The catalyst bag 115 is installed in the catalyst cavity 112. When the photolysis component 100 is working, the UV lamp 114 emits ultraviolet light to irradiate the catalyst bag 115 to generate ozone. The ozone is released into the photolysis chamber 220 through the release holes 113.

[0026] It should be noted that, as Figure 12As shown, a range hood typically consists of three parts: a fume hood 20, a purification module 10, and a fan assembly. The fume hood 20, located at the bottom, captures cooking fumes, preventing them from spreading into the kitchen space and collecting grease. The purification module 10, located in the middle, purifies the fumes captured by the fume hood 20 to ensure they meet emission standards. The fan assembly, located at the top, powers the flow of cooking fumes, drawing them from the fume hood 20 to the purification module 10 for filtration. The filtered fumes are then discharged into the atmosphere through the fan assembly.

[0027] It is understood that the purification module 10 contains an atomizing component 300 and a condensing component 400. The atomizing component 300 releases water mist, which combines with some of the oil fumes to liquefy and form oil stains. The condensing component 400 can release cold ions, which partially liquefy upon contact with the oil fumes to form oil stains. In this embodiment, the purification module 10 includes a housing 200, which has a purification chamber 210, a photolysis chamber 220, and a filter chamber 230 arranged along its height. The purification chamber 210, photolysis chamber 220, and filter chamber 230 are arranged from bottom to top. The purification chamber 210 is located in... Below, the purification chamber 210 is connected to the smoke collection hood 20. The photolysis chamber 220 is located above the purification chamber 210, and the filter chamber 230 is located above the photolysis chamber 220. The oil fumes captured by the smoke collection hood 20 first enter the purification chamber 210. The atomizing component 300 and the condensing component 400 in the purification chamber 210 first undergo purification. The oil fumes purified in the purification chamber 210 then enter the photolysis chamber 220 through the confluence port 221 and are purified by the photolysis component 100. They then enter the filter chamber 230 and are purified by the filter component 500, thus realizing the purification of oil fumes by the filter module.

[0028] In this embodiment, the mounting base 110 has a mounting cavity 111 and a catalyst cavity 112 arranged around the mounting cavity 111. A plurality of release holes 113 are provided around the mounting base 110. A UV lamp 114 is installed inside the mounting cavity 111, and a catalyst bag 115 is installed inside the catalyst cavity 112. When the photolysis assembly 100 is working, the UV lamp 114 is turned on, emitting ultraviolet light into the surrounding catalyst cavity 112 to irradiate the catalyst bag 115, causing O2 molecules to decompose into oxygen atoms (O) inside the photolysis cavity 220. The oxygen atoms combine with O2 to generate ozone, thus filling the photolysis cavity 220 with ozone. After being purified by the atomizing component 300 and the condensing component 400, the oil fumes enter the photolysis chamber 220. Inside the photolysis chamber 220, ozone and oil fumes fully combine, effectively removing harmful substances from the oil fumes and ensuring that the oil fumes emitted into the atmosphere are free of harmful substances, thus avoiding environmental pollution. Furthermore, catalytic chambers 112 are arranged around the mounting chamber 111, and catalyst bags 115 are installed inside the catalytic chambers 112. This significantly improves the ozone production effect, ensuring the ozone content within the photolysis chamber 220, thereby guaranteeing the effectiveness of the photolysis component 100 in removing harmful substances from the oil fumes. As one embodiment, the catalyst bag 115 can be manganese dioxide, which provides a good catalytic effect.

[0029] like Figure 1 and 2 As shown, the cross-sectional profile of the mounting cavity 111 is rhomboid. The mounting cavity 111 has four end-to-end connected edges and a first end point 1111 and a second end point 1112 arranged opposite to each other. A catalytic cavity 112 is formed on each of the four edges away from the mounting cavity 111. A catalytic cavity 112 is also formed on the first end point 1111 and the second end point 1112 away from the mounting cavity 111, so that catalytic cavities 112 are arranged on the periphery of the mounting cavity 111.

[0030] In this embodiment, the cross-sectional profile of the installation cavity 111 is diamond-shaped. In the cross-sectional profile of the installation cavity 111, the diamond-shaped installation cavity 111 facilitates the UV lamp 114 to emit ultraviolet rays in all directions. A catalytic cavity 112 is formed in the direction away from the installation cavity 111 on each of the four edges. The left and right sides of the installation cavity 111 have a first end point 1111 and a second end point 1112. A catalytic cavity 112 is also formed in the direction away from the installation cavity 111 at the first end point 1111 and the second end point 1112. In this way, six catalytic cavities 112 surround the installation cavity 111, and the ultraviolet rays emitted by the UV lamp 114 in the installation cavity 111 can diverge to the catalytic cavities 112 on the outer periphery of the installation cavity 111. The catalyst bag 115 is installed in the catalytic cavity 112. In this way, the preparation effect of ozone can be greatly improved. Of course, the number of catalytic cavities 112 can also be adjusted according to the actual situation, more than six or less than six are both acceptable. The cross-sectional profile of the installation cavity 111 can also be other shapes, such as circular or regular polygon, as long as it can ensure that the ultraviolet rays emitted by the UV lamp 114 can be evenly diffused in all directions.

[0031] As Figure 2 shown, the cross-sectional profile of the mounting base 110 is trapezoidal in reverse. The upper side length of the mounting base 110 is w1, 38 cm ≤ w1 ≤ 42 cm. The lower side length of the mounting base 110 is w2, 28 cm ≤ w2 ≤ 32 cm. The height of the mounting base 110 is j, 10 cm ≤ j ≤ 14 cm. A number of light-transmitting holes 1113 are provided on the periphery of the installation cavity 111. The diameter of the light-transmitting hole 1113 is r1, and the diameter of the release hole 113 is r2. The diameter r1 of the light-transmitting hole 1113 and the diameter r2 of the release hole 113 satisfy: r1 < r2, where r1 ≤ 50 μm and r2 ≤ 100 μm. The material of the mounting base 110 is foam titanium plate. The plate thickness of the installation cavity 111 is b1, and the plate thickness of the catalytic cavity 112 is b2. The plate thickness b1 of the installation cavity 111 and the plate thickness b2 of the catalytic cavity 112 satisfy: b1 < b2, where b1 ≤ 8 mm and b2 ≤ 10 mm.

[0032] In this embodiment, the cross-sectional profile of the mounting base 110 is an inverted trapezoid. The upper side length of the mounting base 110 is w1, 38cm≤w1≤42cm, the lower side length of the mounting base 110 is w2, 28cm≤w2≤32cm, and the height of the mounting base 110 is j, 10cm≤j≤14cm. The cross-sectional profile of the mounting base 110 is an inverted trapezoid, with the upper side length w1 greater than the lower side length w2. Preferably, the upper side length w1 is equal to 40cm, the lower side length w2 is equal to 30cm, and the height j is equal to 12cm. With this design, when the photolysis component 100 prepares ozone, it is convenient for the prepared ozone to diffuse to both sides of the photolysis cavity 220, so as to improve the effect of removing harmful substances in the oil fume. The mounting cavity 111 has several light-transmitting holes 1113 around its periphery to ensure that the ultraviolet rays emitted by the UV lamp 114 can irradiate the surrounding catalytic cavity 112 through the light-transmitting holes 1113. The diameter r1 of the light-transmitting hole 1113 is smaller than the diameter r2 of the release hole 113, satisfying r1≤50μm and r2≤100μm. This design ensures the uniformity of the ultraviolet rays emitted by the UV lamp 114 in all directions, and that after ozone is emitted, the ultraviolet rays can diffuse smoothly through the release hole 113 into the photolysis cavity 220. Furthermore, it can effectively prevent oil fume from polluting the UV lamp 114. The mounting base 110 is made of foamed titanium board, and the edges of the mounting base 110 are edged with sheet metal. The foamed titanium board has good chemical stability. The thickness b1 of the mounting cavity 111 is less than the thickness b2 of the catalytic cavity 112, b1≤8mm, b2≤10mm. This ensures the overall structural strength of the mounting base 110 without occupying too much space in the photolysis cavity 220, thus avoiding the purification module 10 from being too large and occupying too much kitchen space.

[0033] Example 2: like Figure 3-7As shown, this embodiment provides a purification module 10, including a housing 200, an atomizing component 300, a condensing component 400, a photolysis component 100 as described in Embodiment 1, and a filtering component 500. The housing 200 has a purification chamber 210, a photolysis chamber 220, and a filtering chamber 230 in the height direction. The bottom of the purification chamber 210 has a first air inlet 211 and a second air inlet 212. The bottom of the photolysis chamber 220 has a confluence port 221, which is offset from both the first air inlet 211 and the second air inlet 212. The top of the photolysis chamber 220 has a first guide port 222 and a second guide port 222. The atomizing component 300 is installed in the purification chamber 210 and is located at the first air inlet 211 and / or the second air inlet 212; the condensing component 400 is installed in the purification chamber 210 and is disposed opposite to the confluence port 221; the photolysis component 100 is installed in the photolysis chamber 220 and is located above the confluence port 221; the filter component 500 is installed in the filter chamber 230 and is located above the first guide port 222 and the second guide port 223.

[0034] In this embodiment, the purification chamber 210, photolysis chamber 220, and filter chamber 230 are arranged from bottom to top along the height direction of the housing 200. That is, along the height direction of the housing 200, the purification chamber 210 is at the bottom and communicates with the fume hood 20. The photolysis chamber 220 is located above the purification chamber 210. The oil fumes captured by the fume hood 20 first enter the purification chamber 210 and are purified there. The purified oil fumes then pass through the confluence port 230. 21. The air enters the photolysis chamber 220 for purification. Specifically, the bottom of the purification chamber 210 has a first air inlet 211 and a second air inlet 212. The bottom of the photolysis chamber 220 has a confluence port 221, which is staggered from the first air inlet 211 and the second air inlet 212. The top of the photolysis chamber 220 has a first guide port 222 and a second guide port 223, which are staggered from the confluence port 221. When the purification module 10 purifies the oil fumes, a portion of the oil fumes entering the housing 200 through the first air inlet 211 (which is offset from the confluence port 221) repeatedly bounces and flows within the purification chamber 210 until it reaches the confluence port 221. From there, it flows into the photolysis chamber 220. The oil fumes, entering the purification chamber 210 through the first air inlet 211 and then flowing into the photolysis chamber 220, exhibit an "S"-shaped trajectory. The flow distance of the oil fumes is greatly increased. After entering the purification chamber 210, the oil fumes repeatedly bounce within the purification chamber 210. Under the conditions of water mist and cold ions released by the atomizing component 300 and the condensing component 400, the oil fumes combine with the water mist and cold ions and violently collide with the body of the purification chamber 210. During the violent collision, the oil fumes will liquefy into oil stains within the purification chamber 210 and drip and collect in the oil stain collection structure of the fume hood 20, thus achieving the purification of the oil fumes. Similarly, some of the oil fumes entering the housing 200 from the second air inlet 212 are staggered with the confluence port 221. This part of the oil fumes repeatedly bounces and flows within the purification chamber 210 until it reaches the confluence port 221, from where it flows into the photolysis chamber 220. The oil fumes bounce and flow from the second air inlet 212 into the purification chamber 210 and into the photolysis chamber 220, and its trajectory is "S". In this way, the flow distance of the oil fumes is greatly increased. After entering the purification chamber 210, this part of the oil fumes repeatedly bounces within the purification chamber 210. Under the conditions of water mist and cold ions released by the atomizing component 300 and the condensing component 400, the oil fumes combine with the water mist and cold ions and undergo violent collisions within the purification chamber 210. During the violent collision process, the oil fumes liquefy into oil stains in the first chamber and drip and collect in the oil stain collection structure of the fume hood 20, thus achieving the purification of the oil fumes.The purification module 10 is staggered from the first air inlet 211 and the second air inlet 212 by the confluence port 221, and staggered from the first guide port 222 and the second guide port 223. This greatly increases the flow distance of the fumes, optimizes the flow path of the fumes in the housing 200, improves the liquefaction effect of the oil in the fumes, and effectively avoids the pollution of the environment by the fumes.

[0035] The atomizing component 300 is installed inside the purification chamber 210 and is located at the first air inlet 211 and / or the second air inlet 212. The atomizing component 300 can release water mist. When oil fumes enter the purification chamber 210 from the first air inlet 211 and / or the second air inlet 212, the water mist released by the atomizing component 300 and the oil fumes can be fully mixed and violently impacted in the purification chamber 210 during the flow, causing the oil fumes to liquefy into oil stains, thus achieving the first step of purification of the oil fumes. The condensing component 400 is installed inside the purification chamber 210 and is positioned opposite to the confluence port 221. The condensing component 400 can emit cold ions. The cold ions combine with the oil fumes to lower the temperature of the oil fumes. When the oil fumes flow in the purification chamber 210, the lower-temperature oil fumes collide with the inner surface of the purification chamber 210 during the flow and collide, causing them to liquefy and form oil stains, thus achieving the second step of purification of the oil fumes. The photolysis component 100 is installed in the photolysis chamber 210. Inside cavity 220, with photolysis component 100 positioned above confluence port 221, photolysis component 100 generates ozone. Oil fumes purified by atomizing component 300 and condensing component 400 within purification cavity 210 enter photolysis cavity 220 through confluence port 221. Photolysis component 100, directly opposite confluence port 221, removes harmful substances from the oil fumes entering photolysis cavity 220 from confluence port 221, achieving the third step of oil fume purification. Filter component 500 is installed within the filter... Inside cavity 230, with filter assembly 500 positioned above the first guide port 222 and the second guide port 223, the e-liquid purified by photolysis assembly 100 flows towards the first guide port 222 and the second guide port 223 on both sides within photolysis cavity 220. It enters filter cavity 230 from the first guide port 222 and / or the second guide port 223. Filter assembly 500 further filters particulate matter and harmful substances from the oil fumes, achieving a fourth step in oil fume purification. Through the multiple purification processes of atomizing assembly 300, condensing assembly 400, photolysis assembly 100, and filter assembly 500, the purification effect of oil fumes is greatly improved, ensuring that the purified oil fumes meet emission standards.

[0036] The purification module 10 of this embodiment, through the photolysis component 100 of embodiment one, enables the harmful substances in the oil fume to be completely purified by the photolysis component 100, preventing the oil fume emitted into the atmosphere from containing harmful substances and effectively avoiding the pollution of the environment by harmful substances in the oil fume.

[0037] like Figure 5-7As shown, the housing 200 includes a main body 240, a diverter plate 250, a confluence assembly 260, and a guide plate 270. The diverter plate 250 is disposed at the bottom of the main body 240, so that the bottom of the main body 240 has a first air inlet 211 and a second air inlet 212. The confluence assembly 260 includes a first confluence plate 261 and a second confluence plate 262, both of which are disposed in the middle of the main body 240. A confluence port 221 is formed between the first confluence plate 261 and the second confluence plate 262. The confluence port 221 and the first air inlet 212 are connected. The air vent 211 and the second air inlet 212 are staggered; the guide plate 270 is disposed on the upper part of the main body 240 so that the upper part of the main body 240 has a first guide port 222 and a second guide port 223, and the guide plate 270 is opposite to the confluence port 221; the guide plate 270 is provided with a plurality of rows of guide holes 271 arranged along the width direction of the main body 240, the plurality of rows of guide holes 271 are arranged in parallel, the diameter of the guide holes 271 in the same row is equal, and the diameter of the guide holes 271 in the middle row gradually increases from the diameter of the guide holes 271 on both sides.

[0038] In this embodiment, the housing structure includes a main body 240, a diverter plate 250, a confluence assembly 260, and a guide plate 270. The main body 240 is an internally connected frame structure. The diverter plate 250 is disposed at the bottom of the main body 240. Specifically, the diverter plate 250 is disposed in the middle of the bottom of the main body 240, so that the diverter plate 250 divides the bottom of the main body 240. A first air inlet 211 and a second air inlet 212 are formed on both sides of the bottom of the main body 240, allowing oil fumes to enter the interior of the main body 240. The first confluence plate 261 and the second confluence plate 262 are both disposed in the middle of the main body 240. Specifically, the first confluence plate 261 and the second confluence plate 262 are disposed in the middle of the main body 240. On two opposite sides of body 240, the first confluence plate 261 faces the first air inlet 211, and the second confluence plate 262 faces the second air inlet 212. A confluence port 221 is formed between the first confluence plate 261 and the second confluence plate 262. Oil fumes enter body 240 from the first air inlets 211 and 212 on both sides of the diverter plate 250. Some oil fumes entering body 240 from the first air inlet 211 will bounce back due to the alignment of the first confluence plate 261 with the first air inlet 211. This means that some oil fumes will repeatedly bounce and flow between the first confluence plate 261 and the diverter plate 250 until they reach the confluence port 221, from which they flow to... The guide holes 271, first guide port 222, and second guide port 223 of the guide plate 270 are discharged. The oil fumes will repeatedly bounce and flow between the first confluence plate 261 and the split plate 250 and flow into the guide plate 270. The flow trajectory is in the reverse "S" shape, which greatly increases the flow distance of the oil fumes. In this way, the atomizing component 300, condensing component 400, photolysis component 100, and filter component 500 installed in the box 200 can fully purify and photolyze the oil fumes, ensuring that the oil fumes are fully purified in the box 200 and the oil fumes discharged into the atmosphere meet the standards. Similarly, some oil fumes entering the main body 240 from the second air inlet 212 are discharged because the second confluence plate 262 is directly opposite the second air inlet 212. The 62 component will have a rebound effect on the oil fumes, meaning that this portion of the oil fumes will repeatedly bounce and flow between the second confluence plate 262 and the diverter plate 250 until it flows to the confluence port 221. From the confluence port 221, it flows to the guide hole 271, the first guide port 222, and the second guide port 223 of the guide plate 270 and is discharged. The oil fumes will repeatedly bounce and flow between the second confluence plate 262 and the diverter plate 250 and flow into the guide plate 270. The flow trajectory is "S" shaped, which greatly increases the flow distance of the oil fumes. The atomizing component 300, the condensing component 400, the photolysis component 100, and the filter component 500 can fully purify and photolyze the oil fumes, ensuring that the oil fumes are fully purified in the housing 200 and that the oil fumes discharged into the atmosphere meet the standards.The housing 200, through the diversion plate 250, the merging component 260, and the guide plate 270, causes the oil fumes entering the main body 240 to move in an "S" or reverse "S" shape, which greatly increases the flow distance of the oil fumes and optimizes the flow path of the oil fumes in the housing 200. This improves the purification, photolysis, and filtration effect of the oil fumes, ensuring that the oil fumes are completely purified in the housing 200 and preventing the discharged oil fumes from polluting the environment.

[0039] A row of guide holes 271 includes several guide holes 271 with equal diameters. The guide holes 271 in the same row have equal diameters. The middle row of guide holes 271 is directly opposite the confluence port 221, and the diameter of the guide holes 271 in the middle row gradually increases towards the guide holes 271 on both sides of the guide plate 270. Preferably, the diameter of the guide holes 271 in the middle row is 3 mm, and the diameter of the outermost row of guide holes 271 is 8 mm. The outermost row of guide holes 271 is close to the first guide port 222 or the second guide port 223. After being purified by the atomizing component 300, the condensing component 400, and the photolysis component 100, the oil fumes containing fine particles flow from the central guide hole 271 to the filter chamber 230, while the oil fumes containing larger particles enter the filter chamber 230 from the guide holes 271 on both sides, or the first guide port 222, or the second guide port 223. In the filter chamber 230, the oil fumes are then filtered by the filter component 500. This design ensures that the oil fumes are evenly distributed in the filter chamber 230, and that the particles in the oil fumes are completely filtered by the filter component 500.

[0040] Furthermore, as one embodiment, the main body 240 includes an upper box structure and a lower box structure; the upper box structure is disposed above the lower box structure, the diverter plate 250 is disposed at the bottom of the lower box structure, the confluence assembly 260 is disposed at the bottom of the upper box structure, and the guide plate 270 is disposed at the upper part of the upper box structure. Both the upper and lower box structures have internal communicating spaces. The upper box structure is fixedly connected to the upper part of the lower box structure to form the main body 240. The diverter plate 250 is disposed at the bottom of the lower box structure, meaning the first air inlet 211 and the second air inlet 212 are on opposite sides of the bottom of the lower box structure, and the first air inlet 211 and the second air inlet 212 communicate with the interior of the lower box structure. The confluence assembly 260 is disposed at the bottom of the upper box structure, meaning the confluence port 221 is located at the bottom of the upper box structure, and similarly, the confluence port 221 is located at the top of the lower box structure. The inlet 221 connects the interior of the lower housing structure with the interior of the upper housing structure. The guide plate 270 is located on the upper part of the upper housing structure, that is, the first guide port 222 and the second guide port 223 are located at the top of the upper housing structure. In this way, after the oil fumes enter the lower housing structure from the first air inlet 211 and the second air inlet 212 at the bottom of the lower housing structure, they flow from the lower housing structure to the upper housing structure in sequence along the reverse "S" or "S" motion trajectory, and flow out from the guide hole 271 or the first guide port 222 or the second guide port 223 on the guide plate 270.

[0041] Of course, the main body 240 may also include a left side plate, a front side plate, a right side plate and a rear side plate. The left side plate, the front side plate, the right side plate and the rear side plate are connected in sequence to form the main body 240. The main body 240 is a frame structure. The diverter plate 250 is set at the bottom of the frame and forms a first air inlet 211 and a second air inlet 212 at the bottom of the frame. The first confluence plate 261 and the second confluence plate 262 are set in the middle of the frame and form a confluence port 221 in the middle of the frame. The guide plate 270 is set in the upper part of the frame and forms a first guide port 222 and a second guide port 223 in the upper part of the frame.

[0042] like Figure 5-7As shown, the main body 240, the diverting plate 250, and the confluence assembly 260 enclose the purification chamber 210; the main body 240, the confluence assembly 260, and the guide plate 270 enclose the photolysis chamber 220; and the main body 240 and the guide plate 270 enclose the filtration chamber 230. The main body 240 has a first side 241 and a second side 242 opposite to the first side 241; the first air inlet 211 is close to the first side 241, and the second air inlet 212 is close to the second side 242; the first confluence plate 261 is close to the first side 241, and the second confluence plate 262 is close to the second side 242; the first guide port 222 is close to the first side 241. The second guide port 223 is close to the second side 242; when the oil fume enters the housing 200, the oil fume enters the purification chamber 210 from the first air inlet 211, flows along the purification chamber 210 toward the confluence port 221, and enters the photolysis chamber 220, so that the oil fume enters the filter chamber 230 from the guide hole 271 or the first guide port 222 or the second guide port 223 of the guide plate 270; and / or, the oil fume enters the purification chamber 210 from the second air inlet 212, flows along the purification chamber 210 toward the confluence port 221, and enters the photolysis chamber 220, so that the oil fume enters the filter chamber 230 from the guide hole 271 or the first guide port 222 or the second guide port 223 of the guide plate 270.

[0043] In this embodiment, the main body 240, the diverter plate 250, and the confluence assembly 260 enclose and form a purification chamber 210. As one embodiment, the interior of the lower housing structure is the purification chamber 210, and the main body 240, the confluence assembly 260, and the guide plate 270 enclose and form a photolysis chamber 220. As another embodiment, the interior of the upper housing structure is the photolysis chamber 220, and the main body 240 and the guide plate 270 enclose and form a filter chamber 230, that is, a filter chamber 230 is formed above the upper housing structure. The main body 240 has a first side 241 and a second side 242 arranged opposite to each other. The first air inlet 211 is close to the first side 241, the second air inlet 212 is close to the second side 242, the first confluence plate 261 is close to the first side 241, the second confluence plate 262 is close to the second side 242, the first guide port 222 is close to the first side 241, and the second guide port 223 is close to the second side 242. Through this design, the oil fumes entering the main body 240 from the first air inlet 211 flow sequentially through the purification chamber 210, the confluence port 221, the photolysis chamber 220, and the guide port. The flow path of the guide hole 271 or the first guide port 222 or the second guide port 223 of the plate 270 and the filter chamber 230 is in the form of an inverted "S" shape. The oil fume entering the main body 240 from the second air inlet 212 flows through the purification chamber 210, the confluence port 221, the photolysis chamber 220, the guide hole 271 or the first guide port 222 or the second guide port 223 of the guide plate 270 and the filter chamber 230 in the form of an "S" shape. In this way, by optimizing the flow path of the oil fume in the main body 240, the purification, photolysis and filtration effect of the oil fume is improved, and the oil fume is completely purified in the purification body.

[0044] like Figure 8 As shown, in the housing 200, a rectangular coordinate system is constructed with the center of the diverter plate 250 as the origin O. The first point of the diverter plate 250 is A1, the second point of the diverter plate 250 is A2, the first point of the first air inlet 211 is B1, the second point of the second air inlet 212 is B2, the first point of the second air inlet 212 is C1, the second point of the second air inlet 212 is C2, and the first point A1 of the diverter plate 250 coincides with the second point B2 of the first air inlet 211. The second point A2 of the flow divider 250 coincides with the first point C1 of the second air inlet 212; wherein, the distance from the first point A1 of the flow divider 250 to the second point A2 of the flow divider 250 is d1, 70cm≤d1≤74cm; the distance from the first point B1 of the first air inlet 211 to the first point B2 of the first air inlet 211 is i1, and the distance from the first point C1 of the second air inlet 212 to the first point C2 of the second air inlet 212 is i2, 13cm≤i1=i2≤17cm.

[0045] The distance from the first point A1 to the second point A2 of the diverter plate 250 is d1, that is, the width of the diverter plate 250 is d1, 70cm≤d1≤74cm, preferably, the width of the diverter plate 250 is 72cm. The distance from the first point B1 to the first point B2 of the first air inlet 211 is i1, and the distance from the first point C1 to the first point C2 of the second air inlet 212 is i2, that is, the distance from the first point B1 to the second point B2 of the second air inlet 212 is i2. The width of the first air inlet 211 is i1, the width of the second air inlet 212 is i2, and the width of the first air inlet 211 and the width of the second air inlet 212 are equal, within the range of 13cm-17cm. Preferably, the width of the first air inlet 211 and the second air inlet 212 is 15cm. With this setting, on the one hand, the size of the cabinet 200 is not too large, which would occupy too much space in the kitchen, and on the other hand, the air intake volume and air intake speed of the first air inlet 211 and the second air inlet 212 are guaranteed.

[0046] like Figure 8 As shown, the first point of the first merging plate 261 is D1, the second point of the first merging plate 261 is D2, the first point of the second merging plate 262 is E1, the second point of the second merging plate 262 is E2, the first point of the merging port 221 is F1, the second point of the merging port 221 is F2, the first point F1 of the merging port 221 coincides with the second point D2 of the first merging plate 261, and the second point F2 of the merging port 221 coincides with the first point E1 of the second merging plate 262; wherein, the distance from the first point D1 of the first merging plate 261 to the first merging plate 262 is... The distance from the second point D2 of the first merging plate 261 is d2, and the distance from the first point E1 of the second merging plate 262 to the second point E2 of the second merging plate 262 is d3, 34cm≤d2=d3≤38cm; the distance from the first point F1 of the merging port 221 to the second point F2 of the merging port 221 is i3, 28cm≤i3≤32cm; the distance from the first point D1 of the first merging plate 261 to the splitting plate 250 is h1, and the distance from the second point E1 of the second merging plate 262 to the splitting plate 250 is h2, 13cm≤h1=h2≤17cm.

[0047] The distance from the first point D1 of the first merging plate 261 to the second point D2 of the first merging plate 261 is d2, and the distance from the first point E1 of the second merging plate 262 to the second point E2 of the second merging plate 262 is d3. 34cm ≤ d2 = d3 ≤ 38cm, meaning the width of the first merging plate 261 and the width of the second merging plate 262 are equal. Preferably, the width of the first merging plate 261 and the second merging plate 262 is 36cm; the first point F of the merging port 221... The distance from point D1 to the second point F2 of the confluence port 221 is i3, where 28cm ≤ i3 ≤ 32cm, meaning the width of the confluence port 221 is i3. Preferably, the width of the confluence port 221 is 30cm. The distance from the first point D1 of the first confluence plate 261 to the diverter plate 250 is h1, and the distance from the second point E1 of the second confluence plate 262 to the diverter plate 250 is h2, where 13cm ≤ h1 = h2 ≤ 17cm. Therefore, the height of the purification chamber 210 is either h1 or h2. The purification chamber 210 is 15cm high. This design ensures that, firstly, the first confluence plate 261 completely blocks the first air inlet 211, causing the fumes to bounce back between the first confluence plate 261 and the diverter plate 250 after entering the purification chamber 210 from the first air inlet 211, ultimately flowing to the confluence port 221. Similarly, the second confluence plate 262 completely blocks the second air inlet 212, allowing the fumes to enter the purification chamber 210 from the second air inlet 212. Then, the oil fumes bounce back between the second confluence plate 262 and the diverter plate 250 and flow to the confluence port 221. On the other hand, the width of the confluence port 221 is twice that of the first air inlet 211 or the second air inlet 212, ensuring that the oil fumes entering from the first air inlet 211 and / or the second air inlet 212 can receive the oil fumes flowing in from the first air inlet 211 and / or the second air inlet 212 after they flow to the confluence port 221, thus preventing the oil fumes from lingering in the purification chamber 210.

[0048] like Figure 8As shown, the first point of the guide plate 270 is G1, the second point of the guide plate 270 is G2, the first point of the first guide port 222 is H1, the second point of the first guide port 222 is H2, the first point of the second guide port 223 is I1, and the second point of the second guide port 223 is I2. The first point G1 of the guide plate 270 coincides with the second point H2 of the first guide port 222, and the second point G2 of the guide plate 270 coincides with the first point I1 of the second guide port 223. The distance from the first point G1 of the guide plate 270 to the first confluence plate 261 is h3, and the distance from the second point G2 of the guide plate 270 to the second confluence plate 262 is h4. 10cm ≤ h3 = h4 ≤ 15cm, and h3 = h4. i1=i2. The distance from the first point G1 of the guide plate 270 to the top of the main body 240 is h5, and the distance from the second point G2 of the guide plate 270 to the top of the main body 240 is h6. 8cm≤h5=h6≤12cm, and h5=h6 <h3=h4。 <h1>

[0049] The distance from the first point G1 of the guide plate 270400 to the first confluence plate 261 is h3, and the distance from the second point G2 of the guide plate 270 to the second confluence plate 262 is h4. 10cm ≤ h3 = h4 ≤ 15cm, meaning the height of the photolysis cavity 220 is h3 or h4. Preferably, the height of the photolysis cavity 220 is 12cm, and h3 = h4. i1=i2, that is, the widths of the first guide port 222 and the second guide port 223 are equal. Preferably, the widths of the first guide port 222 and the second guide port 223 are 16cm. With this design, the oil fumes in the photolysis chamber 220 can all flow to the filter chamber 230 through the guide holes 271 on the guide plate 270, thus avoiding the oil fumes from lingering in the photolysis chamber 220.<h1>

[0050] like Figure 8As shown, the distance from the first point G1 of the guide plate 270 to the top of the main body 240 is h5, and the distance from the second point G2 of the guide plate 270 to the top of the main body 240 is h6. 8cm ≤ h5 = h6 ≤ 12cm, and h5 = h6. <h3=h4。

[0051] The distance from the first point G1 of the guide plate 270 to the top of the main body 240 is h5, and the distance from the second point G2 of the guide plate 270 to the top of the main body 240 is h6. 8cm≤h5=h6≤12cm, meaning the height of the filter chamber 230 is h5 or h6. Preferably, the height of the filter chamber 230 is 10cm. The height of the filter chamber 230 is less than the height of the photolysis chamber 220, and the height of the photolysis chamber 220 is less than the height of the purification chamber 210. When using this housing 200 to purify oil fumes, the oil fumes enter the purification chamber 210 from the first air inlet 211 and the second air inlet 212. The atomizing component 300 and the condensing component 400 perform the first and second steps of purification on the oil fumes. The fumes then enter the photolysis chamber 220 from the confluence port 221. After the photolysis component 100 performs the third step of purification on the oil fumes, they enter the filter chamber through the first guide port 222 or the second guide port 223 or the guide port. In the purification chamber 230, the filter assembly 500 performs the fourth step of purification of the oil fumes. Since the oil fumes and oil stains are most concentrated in the purification chamber 210, the height of the purification chamber 210 is relatively higher than that of the photolysis chamber 220 and the filter chamber 230. This ensures that the oil fumes are fully purified in the purification chamber 210 first. After being purified by the atomizing assembly 300 and the condensing assembly 400 in the purification chamber 210, the oil stains are reduced. Therefore, the height of the photolysis chamber 220 can be smaller than that of the purification chamber 210. The photolysis assembly 100 in the photolysis chamber 220 can fully purify the oil fumes. Similarly, after being purified by the photolysis assembly 100 in the photolysis chamber 220, the oil stains and harmful substances are further reduced. The height of the filter chamber 230 can be smaller than that of the photolysis chamber 220. Thus, the thickness of the filter assembly 500 in the filter chamber 230 can be reduced to completely filter and purify the oil fumes. The housing 200 is designed such that the height of the filter chamber 230 is less than the height of the photolysis chamber 220, and the height of the photolysis chamber 220 is less than the height of the purification chamber 210. On the one hand, this ensures a reasonable internal structure arrangement of the main body 240, optimizes the flow path of oil fumes within the main body 240, and improves the purification effect of oil fumes. On the other hand, it effectively reduces the thickness of the filter component 500 in the filter chamber 230, greatly saving costs.

[0052] like Figure 4 , 9As shown in Figure 10, the atomizing assembly 300 includes an atomizer (not shown) and at least one atomizing tube 310; the atomizer is installed inside the housing 200, and the atomizing tube 310 is installed inside the purification chamber 210, with the atomizing tube 310 located at the first air inlet 211 and / or the second air inlet 212; a plurality of atomizing holes 311 are evenly arranged on the atomizing tube 310, the plurality of atomizing holes 311 being arranged along the length direction of the atomizing tube 310, and the direction of the atomizing holes 311 facing the first air inlet 211 and / or the second air inlet 212; the condensation assembly 400 includes a cold ion emitter (not shown) and at least one cold ion emission tube 410; the cold ion emitter is installed inside the housing 200, and the cold ion emission tube 410 is located at the first air inlet 211 and / or the second air inlet 212; the atomizing assembly 400 includes a cold ion emitter (not shown) and at least one cold ion emission tube 410; the cold ion emitter is installed inside the housing 200, and the cold ion emission tube 410 is located at the first air inlet 211 and / or the second air inlet 212; the atomizing assembly 400 includes a cold ion emitter (not shown) and at least one cold ion emission tube 410. 10 is installed inside the purification chamber 210, and the cold ion emission tube 410 is arranged opposite to the confluence port 221; the cold ion emission tube 410 has a first arc surface 411 and a second arc surface 412 opposite to the first arc surface 411, the first arc surface 411 is close to the first air inlet 211, the second arc surface 412 is close to the second air inlet 212, the first arc surface 411 is provided with a plurality of rows of first emission holes 4111 arranged along the length direction of the cold ion emission tube 410, the first emission holes 4111 facing the first air inlet 211, the second arc surface 412 is provided with a plurality of rows of second emission holes 4121 arranged along the length direction of the cold ion emission tube 410, the second emission holes 4121 facing the second air inlet 212.

[0053] In this embodiment, the atomizer is a common atomizer on the market, which is existing technology. The atomizer can produce water mist, and its structure and principle will not be described in detail here. The atomizing tube 310 is connected to the mist outlet of the atomizer. The water mist produced by the atomizer can be released into the purification chamber 210 through the atomizing tube 310. Specifically, the atomizing tube 310 is set at the first air inlet 211 or the second air inlet 212. Preferably, both the first air inlet 211 and the second air inlet 212 are provided with atomizing tubes 310. When the oil fumes enter the purification chamber 210 from the first air inlet 211 and the second air inlet 212, they combine with the water mist released from the atomizing tube 310 in the first instant. After the oil fumes and water mist combine, they flow in the purification chamber 210 and collide with the first collision component 600, liquefying into oil stains, so as to achieve the first step of purification of oil fumes. A plurality of atomizing holes 311 are arranged along the length of the atomizing tube 310, and the atomizing holes 311 are oriented towards the first air inlet 211 and / or the second air inlet 212. When the oil fumes enter the purification chamber 210 from the first air inlet 211 and / or the second air inlet 212, it ensures that the water mist released by the atomizing tube 310 can directly mix with the oil fumes, ensuring the liquefaction effect of the oil fumes. The cold ion emitter is a common cold ion emitter on the market, which is existing technology and can emit ions with low temperature. Its structure and principle will not be described in detail here. The cold ion emission tube 410 is connected to the cold ion emitter. The cold ions prepared by the cold ion emitter are emitted into the purification chamber 210 through the cold ion emission tube 410. When the oil fumes enter the purification chamber 210, the cold ions emitted into the purification chamber 210 combine with the oil fumes to cool them down. When the oil fumes flow in the purification chamber 210 and collide with the first collision component 600, the oil fumes with lower temperature will liquefy to form oil stains, thereby achieving the second step of purification of the oil fumes. The first emission hole 4111 of the first arc surface 411 on the cold ion emission tube 410 faces the first air inlet 211, and the second emission hole 4121 of the second arc surface 412 on the cold ion emission tube 410 faces the second air inlet 212. After the oil fumes enter the purification chamber 210 from the first air inlet 211 and / or the second air inlet 212, they flow towards the confluence port 221. The cold ions emitted from the first emission hole 4111 are directly opposite the oil fumes entering from the first air inlet 211, and the cold ions emitted from the second emission hole 4121 are directly opposite the oil fumes entering from the second air inlet 212, ensuring that the cold ions can fully combine with the oil fumes, ensuring the cooling effect of the oil fumes, and further improving the purification effect of the oil fumes.

[0054] like Figure 4 and 11As shown, the filter assembly 500 includes a filter cotton plate 510; the filter cotton plate 510 is installed in the filter chamber 230, and the cross-section of the filter cotton plate 510 is serrated so that the filter cotton plate 510 has a plurality of filter channels 511 in its width direction. The filter channels 511 extend through the length direction of the filter cotton plate 510, and the filter channels 511 are arranged opposite to the guide hole 271 and / or the first guide port 222 and / or the second guide port 223.

[0055] In this embodiment, the filter cotton plate 510 has several filter channels 511 along its width. The filter channels 511 are arranged opposite to the guide holes 271, the first guide port 222, and the second guide port 223. The filter channels 511 extend through the length of the filter panel, meaning that the guide ports in different columns are connected to the filter channels 511. When the oil fumes purified by the atomizing component 300, the condensing component 400, and the photolysis component 100 in the purification module 10 enter different filter channels 511 through different columns of guide holes 271, the first guide port 222, or the second guide port 223, the oil fumes can flow within the filter channels 511. Thus, the filter cotton plate 510 can completely filter and purify the oil fume particles, ensuring that the oil fumes meet emission standards and effectively preventing environmental pollution from the emitted oil fumes. As one embodiment, the filter cotton plate 510 is made by pressing filter cotton into a plate shape and then folding it to have several filter channels 511 arranged along its width.

[0056] like Figure 4 As shown, the purification module 10 further includes a first collision component 600 and a second collision component 700; the first collision component 600 is installed in the purification chamber 210, and the first collision component 600 includes a plurality of metal wire meshes stacked along the height direction of the purification chamber 210; the second collision component 700 is installed in the photolysis chamber 220, and the second collision component 700 includes a plurality of metal wire meshes stacked along the length direction of the photolysis chamber 220.

[0057] In this embodiment, the metal mesh of the first collision component 600 is stacked in the purification chamber 210 in the height direction. After the oil fumes enter the purification chamber 210 from the first air inlet 211 and the second air inlet 212, they flow towards the confluence port 221. In this way, the oil fumes need to pass through the horizontally stacked metal mesh during the flow process, which greatly increases the probability of the oil fumes hitting the metal mesh. Under the state of water mist and cold ions released by the atomizing component 300 and the condensing component 400, the oil fumes combine with the water mist and cold ions and then violently collide with the first collision component 600. During the violent collision process, the oil fumes liquefy into oil stains on the metal mesh of the first collision component 600, which greatly improves the liquefaction effect of the oil fumes. The metal mesh of the second collision component 700 is stacked along the length of the photolysis chamber 220. As the oil fumes flow towards both sides of the confluence port 221, when the oil fumes flow from the confluence port 221 into the first guide port 222 or the second guide port 223 on the upper sides of the photolysis chamber 220, or through the guide holes 271 on both sides of the guide plate 270, the oil fumes need to pass through the vertically stacked metal mesh during the flow process. This greatly increases the probability of the oil fumes colliding with the metal mesh, further improving the liquefaction effect of the oil fumes. Through the first collision component 600 and the second collision component 700, the purification effect of the oil fumes is greatly improved.

[0058] Example 3: like Figure 12 As shown, this embodiment provides a range hood, including a smoke collection hood 20, a purification module 10 as described in Embodiment 2, and a fan assembly (not shown in the figure); the purification module 10 is installed above the smoke collection hood 20; the fan assembly is installed above the purification module 10.

[0059] In this embodiment, the fume hood 20 is located at the bottom of the range hood. The fume hood 20 is used to capture oil fumes, prevent the oil fumes from spreading into the kitchen space, and collect oil stains. The purification module 10 is located in the middle of the range hood. The oil fumes are purified and filtered through multiple processes by the atomizing component 300, condensing component 400, photolysis component 100, and filter component 500. The oil fumes captured by the fume hood 20 enter the purification module 10 and are purified and filtered by the atomizing component 300, condensing component 400, photolysis component 100, and filter component 500 to form oil fumes that meet emission standards. The fan component is located at the top of the range hood. The fan component can provide power for the flow of oil fumes. The fan component includes at least one fan. The fan component draws the oil fumes captured by the fume hood 20 into the purification module for purification and filtration. The oil fumes after purification and filtration are discharged into the atmosphere through the fan component. This range hood, through the purification module 10 in Embodiment 2, optimizes the flow path of oil fumes and performs multiple purification and filtration processes on the oil fumes, greatly improving the purification effect of the oil fumes and ensuring that the oil fumes purified by the range hood meet emission standards.
