Description

Technical Field

[0001] This invention belongs to the field of smoke purification equipment technology, specifically relating to 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 oil stains, thus polluting the environment. Summary of the Invention

[0024] Example 1: like Figure 1-5 As shown, this embodiment provides a purification module 10, including a housing 100 and a first collision component 200; the housing 100 has a first space 110 and a second space 120 arranged along its height direction; the bottom of the first space 110 has a first air inlet 111 and a second air inlet 112; the bottom of the second space 120 has a confluence port 121, which is offset from the first air inlet 111 and the second air inlet 112; the top of the second space 120 has a first guide port 122 and a second guide port 123; the first collision component 200 is installed in the first space 110, and the first collision component 200 includes a plurality of metal wire meshes stacked along the height direction of the first space 110.

[0025] It should be noted that a range hood typically consists of three parts: a fume hood 20, a purification module 10, and a fan assembly. The fume hood 20 is located at the bottom of the range hood; it captures cooking fumes to prevent them from spreading into the kitchen and also collects grease. The purification module 10 is located in the middle of the range hood; it purifies the fumes captured by the fume hood 20 to ensure they meet emission standards. The fan assembly is located at the top of the range hood; it 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.

[0026] It is understood that the purification module 10 contains an atomizing module and a condensing module. The atomizing module releases water mist, which combines with some of the oil fumes to liquefy and form oil stains. The condensing module can release cold ions, which partially liquefy upon contact with the oil fumes to form oil stains. In this embodiment, the housing 100 has a first space 110 and a second space 120 arranged along its height direction. The first space 110 and the second space 120 are arranged from bottom to top, with the first space 110 at the bottom and communicating with the fume hood 20. The second space 120 is located above the first space 110. The fumes captured by the fume hood 20 first enter the first space 110, where they undergo purification. The purified fumes then enter the second space 120 for further purification via the confluence port 121. Specifically, the bottom of the first space 110 has a first air inlet 111 and a second air inlet 112, and the bottom of the second space 120 has a confluence port 121. The confluence port 121 is staggered from both the first air inlet 111 and the second air inlet 112. The top of the second space 120 has a first guide port 122 and a second guide port. 123. When the purification module 10 purifies the fumes, a portion of the fumes entering the main body 140 from the first air inlet 111 is offset from the confluence port 121. This portion of the fumes repeatedly bounces and flows within the first space 110 until it reaches the confluence port 121, from where it flows into the second space 120. The fumes bounce and flow from the first air inlet 111 into the first space 110 and then into the second space 120, their trajectory being "S"-shaped. This greatly increases the flow distance of the fumes. Due to the first collision component 2... The 00 includes several metal wire meshes stacked along the height direction of the first space 110. After the oil fumes enter the first space 110, they undergo repeated rebound motion within the first space 110. Under the conditions of water mist and cold ions released by the atomizing component 400 and the condensing component 500, the oil fumes combine with the water mist and cold ions and violently collide with the first collision component 200. During the violent collision, the oil fumes liquefy into oil stains on the metal wire mesh of the first collision component 200 and drip and collect in the oil stain collection structure of the fume hood 20, thereby purifying the oil fumes.Similarly, the oil fumes entering the main body 140 from the second air inlet 112 are staggered with the confluence port 121. This portion of the oil fumes repeatedly bounces and flows within the first space 110 until it reaches the confluence port 121, from where it flows into the second space 120. The oil fumes entering the first space 110 from the second air inlet 112 and then flowing into the second space 120 exhibit an "S"-shaped trajectory, thus significantly increasing the flow distance. After entering the first space 110, this portion of the oil fumes undergoes repeated bouncing motion within the first space 110, and the water mist and condensate released by the atomizing component 400 and the condensing component 500 further contribute to its flow. In the ionized state, the oil fumes combine with water mist and cold ions and then violently collide with the first collision component 200. During the violent collision, the oil fumes liquefy into oil stains on the metal wire mesh of the first collision component 200 and drip and collect in the oil stain collection structure of the fume hood 20, thus purifying the oil fumes. Furthermore, in the height direction of the first space 110 where the metal wire mesh is stacked, after the oil fumes enter the first space 110 from the first air inlet 111 and the second air inlet 112, they flow towards the confluence port 121. In this way, during the flow, the oil fumes need to pass through the horizontally stacked metal wire mesh, which greatly increases the probability of the oil fumes colliding with the metal wire mesh and improves the liquefaction effect of the oil fumes. In this purification module 10, the confluence port 121 is staggered from both the first air inlet 111 and the second air inlet 112. The stacked metal wire mesh is arranged in the height direction of the first space 110, which greatly increases the flow distance of the oil fumes and optimizes the flow path of the oil fumes in the box 100. After violently colliding with the first collision component 200, the oil stains are fully liquefied, which improves the liquefaction effect of the oil stains in the oil fumes and effectively avoids oil fume pollution of the environment.

[0027] like Figure 2 As shown, the purification module 10 further includes a second collision component 300; the second collision component 300 is installed in the second space 120, and the second collision component 300 includes a plurality of metal wire meshes stacked along the length direction of the second space 120.

[0028] In this embodiment, the oil fumes purified by the first space 110 enter the second space 120 through the confluence port 121. The oil fumes flow to both sides of the confluence port 121. The second collision component 300 is installed in the second space 120. The metal mesh of the second collision component 300 is stacked and arranged in the length direction of the second space 120. When the oil fumes flow from the confluence port 121 to the first guide port 122 and the second guide port 123 on both sides above the second space 120, 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 hitting the metal mesh and further improves the liquefaction effect of the oil fumes.

[0029] like Figure 2 and5 As shown, the housing 100 also has a third space 130; the third space 130 is located above the second space 120; the second space 120 is connected to the third space 130 through the first guide port 122 and the second guide port 123; the purification module 10 also includes an atomizing component 400, a condensing component 500, a photolysis component 600, and a filter component 700; the atomizing component 400 is installed in the first space 110, and the atomizing component 400 is located in the first space 110. The air inlet 111 and / or the second air inlet 112 are located at the following locations: the condenser assembly 500 is installed in the first space 110 and is disposed opposite to the confluence port 121; the photolysis assembly 600 is installed in the second space 120 and is located above the confluence port 121; the filter assembly 700 is installed in the third space 130 and is located above the first guide port 122 and the second guide port 123.

[0030] In this embodiment, the third space 130 is located above the second space 120. The first space 110 and the second space 120 are connected through a confluence port 121. The second space 120 and the third space 130 are connected through a first guide port 122 and a second guide port 123. The fumes can enter the first space 110 from the first air inlet 111 and / or the second air inlet 112, flow to the confluence port 121 in the first space 110, enter the second space 120 through the confluence port 121, and then flow from the second space 120 to the first guide port 122 and the second guide port 123, and finally enter the third space 130. This allows the fumes to flow in an "S" or reverse "S" shape within the housing 100, increasing the flow path of the fumes within the housing 100 and ensuring that the fumes are fully purified within the housing 100. This purification module 10 also includes an atomizing component 400, a condensing component 500, a photolysis component 600, and a filtering component 700. Specifically, the atomizing component 400 is installed in the first space 110 and is located at the first air inlet 111 and / or the second air inlet 112. The atomizing component 400 can release water mist. When oil fumes enter the first space 110 from the first air inlet 111 and / or the second air inlet 112, the water mist released by the atomizing component 400 and the oil fumes can be fully mixed, and during the flow process, the first... The oil fumes violently collide within space 110 and with the first collision component 200, liquefying the oil fumes into oil stains, thus achieving the first step of purification. A condensation component 500 is installed within the first space 110 and is positioned opposite the confluence port 121. The condensation component 500 emits cold ions, which combine with the oil fumes to lower their temperature. As the oil fumes flow through the first space 110, the cooled oil fumes collide with the inner surface of the first space 110 or the first collision component 200 during the flow and collision process. The process involves liquefaction to form oil slicks, achieving a second step in the purification of the fumes. The photolysis component 600 is installed within the second space 120, positioned above the confluence port 121. This component generates ozone. The fumes, purified by the atomizing component 400 and condensing component 500 in the first space 110, enter the second space 120 through the confluence port 121. The photolysis component 600, directly opposite the confluence port 121, removes harmful substances from the fumes entering the second space 120, thus achieving purification of the fumes. The third step of purification involves installing the filter assembly 700 within the third space 130, positioned above the first guide port 122 and the second guide port 123. The e-liquid purified by the photolysis assembly 600 flows through the second space 120 towards the first guide port 122 and the second guide port 123 on both sides, entering the third space 130 from the first guide port 122 and / or the second guide port 123. The filter assembly 700 can further filter particulate matter and harmful substances in the oil fumes, thus achieving the fourth step of purification for the oil fumes.Through multiple purification processes including atomizing component 400, condensing component 500, photolysis component 600, and filtration component 700, the purification effect of oil fumes is greatly improved, ensuring that the purified oil fumes meet emission standards.

[0031] like Figure 3-5 As shown, the housing 100 includes a main body 140, a diverter plate 150, a confluence assembly 160, and a guide plate 170. The diverter plate 150 is disposed at the bottom of the main body 140, so that the bottom of the main body 140 has a first air inlet 111 and a second air inlet 112. The confluence assembly 160 includes a first confluence plate 161 and a second confluence plate 162, both of which are disposed in the middle of the main body 140. A confluence port 121 is formed between the first confluence plate 161 and the second confluence plate 162, and the confluence port 121 is connected to the first air inlet 170. The first and second air inlets 111 and 112 are staggered. The guide plate 170 is disposed on the upper part of the main body 140 so that the upper part of the main body 140 has a first guide port 122 and a second guide port 123. The guide plate 170 is opposite to the confluence port 121. The guide plate 170 is provided with several rows of guide holes 171 arranged along the width direction of the main body 140. The several rows of guide holes 171 are arranged in parallel. The guide holes 171 in the middle row are directly opposite the confluence port 121. The diameter of the guide holes 171 in the middle row gradually increases towards the diameter of the guide holes 171 on both sides.

[0032] In this embodiment, the housing 100 structure includes a main body 140, a diverter plate 150, a confluence assembly 160, and a guide plate 170. The main body 140 is an internally connected frame structure. The diverter plate 150 is disposed at the bottom of the main body 140. Specifically, the diverter plate 150 is disposed in the middle of the bottom of the main body 140, so that the diverter plate 150 divides the bottom of the main body 140. A first air inlet 111 and a second air inlet 112 are formed on both sides of the bottom of the main body 140, allowing oil fumes to enter the interior of the main body 140. The first confluence plate 161 and the second confluence plate 162 are both disposed in the middle of the main body 140. Specifically, the first confluence plate 161 and the second confluence plate 170 are disposed in the middle of the main body 140. Plate 162 is disposed on two opposite sides of the main body 140. The second confluence plate 162 is directly opposite the second air inlet 112. A confluence port 121 is formed between the first confluence plate 161 and the second confluence plate 162. That is, the fumes enter the main body 140 from the first air inlet 111 and the second air inlet 112 on both sides of the diverting plate 150. The fumes entering the main body 140 from the first air inlet 111 will have a rebound effect due to the first confluence plate 161 being directly opposite the first air inlet 111. That is, the fumes will repeatedly bounce and flow between the first confluence plate 161 and the diverting plate 150 until they flow to the confluence port 121, and from the confluence port 121 they will flow to the guide plate 170. The fumes are discharged through the flow holes 171, the first guide port 122, and the second guide port 123. The fumes repeatedly bounce and flow between the first confluence plate 161 and the splitter plate 150, eventually flowing into the guide plate 170. The flow trajectory is an inverted "S" shape, greatly increasing the flow distance of the fumes. Thus, the atomizing component 400, condensing component 500, photolysis component 600, and filter component 700 installed in the housing 100 can fully purify and photolyze the fumes, ensuring that the fumes are fully purified within the housing 100 and that the fumes discharged into the atmosphere meet standards. Similarly, some fumes entering the main body 140 from the second air inlet 112 are affected by the second confluence plate 162 being directly opposite the second air inlet 112. The second confluence plate 162 will... The fumes exhibit a rebound effect, meaning that this portion of the fumes repeatedly bounces and flows between the second confluence plate 162 and the diverter plate 150 until it reaches the confluence port 121. From the confluence port 121, it flows to the guide holes 171, the first guide port 122, and the second guide port 123 of the guide plate 170 for discharge. The fumes repeatedly bounce and flow between the second confluence plate 162 and the diverter plate 150 and flow into the guide plate 170, with a flow trajectory in an "S" shape. This greatly increases the flow distance of the fumes. The atomizing component 400, the condensing component 500, the photolysis component 600, and the filtering component 700 can fully purify and photolyze the fumes, ensuring that the fumes are fully purified in the housing 100 and that the fumes discharged into the atmosphere meet the standards.The chamber 100, through the diversion plate 150, the merging component 160, and the guide plate 170, causes the oil fumes entering the main body 140 to move in an "S" and reverse "S" shape, which greatly increases the flow distance of the oil fumes and optimizes the flow path of the oil fumes within the structure of the purification chamber 100. This improves the purification, photolysis, and filtration effects of the oil fumes, ensuring that the oil fumes are completely purified within the chamber 100 and preventing the discharged oil fumes from polluting the environment. In addition, the guide plate 170 is provided with several rows of guide holes 171 arranged along the width direction of the main body 140. The middle row of guide holes 171 is directly opposite the confluence port 121, and the diameter of the guide holes 171 in the middle row gradually increases towards the guide holes 171 on both sides. Preferably, the diameter of the guide holes 171 in the middle row is 3mm, and the diameter of the guide holes 171 in the outermost row is 8mm. After the oil fume is photolyzed by the photolysis component 600, the oil fume containing fine particles flows from the middle guide hole 171 to the third space 130, while the oil fume containing larger particles enters the third space 130 from the guide holes 171 on both sides, or the first guide port 122, or the second guide port 123. In the third space 130, it is then filtered by the filter component 700. Through this design, it is ensured that the oil fume is evenly distributed in the third space 130, and that the particles in the oil fume can be completely filtered by the filter component 700.

[0033] In one embodiment, the main body 140 includes an upper housing structure and a lower housing structure. The upper housing structure is located above the lower housing structure, the diverter plate 150 is located at the bottom of the lower housing structure, the confluence assembly 160 is located at the bottom of the upper housing structure, and the guide plate 170 is located at the upper part of the upper housing structure. Both the upper and lower housing structures have communicating spaces inside. The upper housing structure is fixedly connected to the upper part of the lower housing structure to form the main body 140. The diverter plate 150 is located at the bottom of the lower housing structure, that is, the first air inlet 111 and the second air inlet 112 are on both sides of the bottom of the lower housing structure, and the first air inlet 111 and the second air inlet 112 communicate with the interior of the lower housing structure. The confluence assembly 160 is located at the bottom of the upper housing structure, that is, the confluence port 121 is located at the bottom of the upper housing structure, and similarly, the confluence port 121 is located at the top of the lower housing structure, through confluence... The opening 121 connects the interior of the lower housing structure with the interior of the upper housing structure. The guide plate 170 is located on the upper part of the upper housing structure, that is, the first guide port 122 and the second guide port 123 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 111 and the second air inlet 112 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" and "S" shaped movement trajectories, and flow out from the guide hole 171, the first guide port 122 or the second guide port 123 on the guide plate 170.

The main body 140 has a first side 180 and a second side 190 opposite to the first side 180. The first air inlet 111 is close to the first side 180, and the second air inlet 112 is close to the second side 190. The first confluence plate 161 is close to the first side 180, and the second confluence plate 162 is close to the second side 190. The first guide port 122 is close to the first side 180. The second guide port 123 is located near the second side 190; when the fumes enter the housing 100, the fumes enter the first space 110 from the first air inlet 111, flow along the first space 110 toward the confluence port 121, and enter the second space 120, so that the fumes enter the third space 130 from the guide hole 171, the first guide port 122, or the second guide port 123 of the guide plate 170; and / or, the fumes enter the first space 110 from the second air inlet 112, flow along the first space 110 toward the confluence port 121, and enter the second space 120, so that the fumes enter the third space 130 from the guide hole 171, the first guide port 122, or the second guide port 123 of the guide plate 170.

[0036] In this embodiment, the main body 140, the diverter plate 150, and the merging assembly 160 enclose a first space 110. As one embodiment, the interior of the lower housing 100 structure is the first space 110, and the main body 140, the merging assembly 160, and the guide plate 170 enclose a second space 120. As another embodiment, the interior of the upper housing 100 structure is the second space 120, and the main body 140 and the guide plate 170 enclose a third space 130, that is, a third space 130 is formed above the upper housing 100 structure. The main body 140 has a first side 180 and a second side 190 arranged opposite to each other. The first air inlet 111 is close to the first side 180, the second air inlet 112 is close to the second side 190, the first confluence plate 161 is close to the first side 180, the second confluence plate 162 is close to the second side 190, the first guide port 122 is close to the first side 180, and the second guide port 123 is close to the second side 190. Through this design, the fumes entering the main body 140 from the first air inlet 111 flow sequentially through the first space 110, the confluence port 121, the second space 120, and the guide plate. The flow path of the oil fumes entering the main body 140 from the second air inlet 112 is reverse "S" shaped. The oil fumes flow through the first space 110, the confluence port 121, the second space 120, the flow path of the guide plate 170 from the guide plate 170 from the second air inlet 112, and the third space 130 in sequence, and the flow path is "S". In this way, by optimizing the flow path of the oil fumes in the main body 140, the purification, photolysis and filtration effect of the oil fumes is improved, and the oil fumes are completely purified in the body.

[0037] like Figure 6 As shown, in the housing 100, a rectangular coordinate system is constructed with the center of the diverter plate 150 as the origin O. The first endpoint of the diverter plate 150 is A1, the second endpoint of the diverter plate 150 is A2, the first endpoint of the first air inlet 111 is B1, the second endpoint of the second air inlet 112 is B2, the first endpoint of the second air inlet 112 is C1, and the second endpoint of the second air inlet 112 is C2. The first endpoint A1 of the diverter plate 150 coincides with the second endpoint B2 of the first air inlet 111. The second endpoint of the flow divider 150, A2, coincides with the first endpoint of the second air inlet 112, C1; wherein, the distance from the first endpoint A1 to the second endpoint A2 of the flow divider 150 is d1, 70cm≤d1≤74cm; the distance from the first endpoint B1 to the first endpoint B2 of the first air inlet 111 is i1, and the distance from the first endpoint C1 to the first endpoint C2 of the second air inlet 112 is i2, 13cm≤i1=i2≤17cm.

[0038] The distance from the first endpoint A1 to the second endpoint A2 of the diverter plate 150 is d1, that is, the width of the diverter plate 150 is d1, 70cm≤d1≤74cm, preferably, the width of the diverter plate 150 is 72cm. The distance from the first endpoint B1 to the first endpoint B2 of the first air inlet 111 is i1, and the distance from the first endpoint C1 to the first endpoint C2 of the second air inlet 112 is i2, that is, the distance from the first endpoint B1 to the second endpoint B2 of the second air inlet 112 is i2, that is, the distance from the first endpoint B1 to the second endpoint C2 of the second air inlet 112 is i2, that is, the distance from the first endpoint B1 to the second endpoint A ... The width of the air inlet 111 is i1, the width of the second air inlet 112 is i2, and the widths of the first air inlet 111 and the second air inlet 112 are equal, within the range of 13cm-17cm. Preferably, the widths of the first air inlet 111 and the second air inlet 112 are 15cm. This arrangement avoids the cabinet 100 from being too large and occupying too much space in the kitchen, while ensuring the air volume and air speed of the first air inlet 111 and the second air inlet 112.

[0039] like Figure 6 As shown, the first endpoint of the first merging plate 161 is D1, the second endpoint of the first merging plate 161 is D2, the first endpoint of the second merging plate 162 is E1, the second endpoint of the second merging plate 162 is E2, the first endpoint of the merging port 121 is F1, the second endpoint of the merging port 121 is F2, the first endpoint F1 of the merging port 121 coincides with the second endpoint D2 of the first merging plate 161, and the second endpoint F2 of the merging port 121 coincides with the first endpoint E1 of the second merging plate 162; wherein, the distance from the first endpoint D1 of the first merging plate 161 to the first merging plate 162 is... The distance from the second endpoint D2 of the merging plate 161 is d2, and the distance from the first endpoint E1 of the second merging plate 162 to the second endpoint E2 of the second merging plate 162 is d3, 34cm≤d2=d3≤38cm; the distance from the first endpoint F1 of the merging port 121 to the second endpoint F2 of the merging port 121 is i3, 28cm≤i3≤32cm; the distance from the first endpoint D1 of the first merging plate 161 to the splitting plate 150 is h1, and the distance from the second endpoint E1 of the second merging plate 162 to the splitting plate 150 is h2, 13cm≤h1=h2≤17cm.

[0040] The distance from the first endpoint D1 of the first merging plate 161 to the second endpoint D2 of the first merging plate 161 is d2, and the distance from the first endpoint E1 of the second merging plate 162 to the second endpoint E2 of the second merging plate 162 is d3. 34cm ≤ d2 = d3 ≤ 38cm, meaning the width of the first merging plate 161 and the width of the second merging plate 162 are equal. Preferably, the width of the first merging plate 161 and the second merging plate 162 is 36cm; the first end of the merging port 121... The distance from point F1 to the second endpoint F2 of the merging port 121 is i3, where 28cm ≤ i3 ≤ 32cm, meaning the width of the merging port 121 is i3. Preferably, the width of the merging port 121 is 30cm. The distance from the first endpoint D1 of the first merging plate 161 to the splitting plate 150 is h1, and the distance from the second endpoint E1 of the second merging plate 162 to the splitting plate 150 is h2, where 13cm ≤ h1 = h2 ≤ 17cm, meaning the height of the first space 110 is h1 or h2. 2. Preferably, the height of the first space 110 is 15cm. With this design, on the one hand, the first confluence plate 161 can completely block the first air inlet 111, and cause the fumes to enter the first space 110 from the first air inlet 111 and then bounce back between the first confluence plate 161 and the diverter plate 150 to the confluence port 121. Similarly, the second confluence plate 162 can completely block the second air inlet 112, and cause the fumes to enter the first space from the second air inlet 112. After 110, the oil fumes bounce back between the second confluence plate 162 and the diverter plate 150 and flow to the confluence port 121. On the other hand, the width of the confluence port 121 is twice that of the first air inlet 111 or the second air inlet 112, ensuring that the oil fumes entering from the first air inlet 111 and / or the second air inlet 112 can receive the oil fumes flowing in from the first air inlet 111 and / or the second air inlet 112 after flowing to the confluence port 121, thus avoiding the oil fumes from lingering in the first space 110.

[0041] like Figure 6As shown, the first endpoint of the guide plate 170 is G1, the second endpoint of the guide plate 170 is G2, the first endpoint of the first guide port 122 is H1, the second endpoint of the first guide port 122 is H2, the first endpoint of the second guide port 123 is I1, and the second endpoint of the second guide port 123 is I2. The first endpoint G1 of the guide plate 170 coincides with the second endpoint H2 of the first guide port 122, and the second endpoint G2 of the guide plate 170 coincides with the first endpoint I1 of the second guide port 123. The distance from the first endpoint G1 of the guide plate 170 to the first confluence plate 161 is h3, and the distance from the second endpoint G2 of the guide plate 170 to the second confluence plate 162 is h4. 10cm ≤ h3 = h4 ≤ 15cm, and h3 = h4. i1=i2. The distance from the first end point G1 of the guide plate 170 to the top of the main body 140 is h5, and the distance from the second end point G2 of the guide plate 170 to the top of the main body 140 is h6. 8cm≤h5=h6≤12cm, and h5=h6 <h3=h4。 <h1>

[0042] The distance from the first endpoint G1 of the guide vane 170400 to the first confluence plate 161 is h3, and the distance from the second endpoint G2 of the guide vane 170 to the second confluence plate 162 is h4. 10cm ≤ h3 = h4 ≤ 15cm, meaning the height of the second space 120 is h3 or h4. Preferably, the height of the second space 120 is 12cm, and h3 = h4. i1=i2, that is, the widths of the first guide port 122 and the second guide port 123 are equal. Preferably, the widths of the first guide port 122 and the second guide port 123 are 16cm. With this design, the oil fumes in the second space 120 can all flow to the third space 130 through the guide port 122 or the second guide port 123 or the guide hole 171 on the guide plate 170, so as to avoid the oil fumes from lingering in the second space 120.<h1>

[0043] like Figure 6As shown, the distance from the first end point G1 of the guide plate 170 to the top of the main body 140 is h5, and the distance from the second end point G2 of the guide plate 170 to the top of the main body 140 is h6. 8cm ≤ h5 = h6 ≤ 12cm, and h5 = h6. <h3=h4。

[0044] The distance from the first end point G1 of the guide plate 170 to the top of the main body 140 is h5, and the distance from the second end point G2 of the guide plate 170 to the top of the main body 140 is h6. 8cm ≤ h5 = h6 ≤ 12cm, meaning the height of the third space 130 is h5 or h6. Preferably, the height of the third space 130 is 10cm. The height of the third space 130 is less than the height of the second space 120, and the height of the second space 120 is less than the height of the first space 110. When this housing 100 is used to purify oil fumes, the oil fumes enter the first space 110 from the first air inlet 111 and the second air inlet 112. The atomizing component 400 and the condensing component 500 perform the first and second steps of purification on the oil fumes, which then enter the second space 120 from the confluence port 121. After the photolysis component 600 performs the third step of purification on the oil fumes, they enter the third space through the first guide port 122, the second guide port 123, or the guide port. 130. The filter assembly 700 performs the fourth step of purification for the oil fumes. Since the first space 110 contains the most oil fumes and grease, its height is relatively higher than that of the second and third spaces 120. This ensures that the oil fumes are fully purified in the first space 110. After being purified by the atomizing assembly 400 and the condensing assembly 500 in the first space 110, the oil fumes have less grease. Therefore, the height of the second space 120 can be slightly lower than that of the first space 110. The photolysis assembly 600 in the second space 120 can fully purify the oil fumes. Similarly, after being purified by the photolysis assembly 600 in the second space 120, the oil fumes have further reduced grease and harmful substances. The height of the third space 130 can be slightly lower than that of the second space 120. Thus, the filter assembly 700 in the third space 130 can be thinner to completely filter and purify the oil fumes. By designing the third space 130 of the housing 100 to be less than the height of the second space 120, and the second space 120 to be less than the height of the first space 110, the internal structure of the main body 140 is arranged reasonably, the flow path of oil fumes in the main body 140 is optimized, and the purification effect of oil fumes is improved. On the other hand, the thickness of the filter component 700 in the third space 130 is effectively reduced, which greatly saves costs.

[0045] like Figure 2 and 7As shown, the atomizing assembly 400 includes an atomizer (not shown) and at least one atomizing tube 410; the atomizer is installed inside the housing 100, the atomizing tube 410 is installed inside the first space 110, and the atomizing tube 410 is located at the first air inlet 111 and / or the second air inlet 112; a plurality of atomizing holes 411 are uniformly arranged on the atomizing tube 410, the plurality of atomizing holes 411 are arranged along the length direction of the atomizing tube 410, and the direction of the atomizing holes 411 is towards the first air inlet 111 and / or the second air inlet 112.

[0046] 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 410 is connected to the mist outlet of the atomizer. The water mist produced by the atomizer can be released into the first space 110 through the atomizing tube 410. Specifically, the atomizing tube 410 is set at the first air inlet 111 or the second air inlet 112. Preferably, both the first air inlet 111 and the second air inlet 112 are provided with atomizing tubes 410. When the oil fumes enter the first space 110 from the first air inlet 111 and the second air inlet 112, they combine with the water mist released from the atomizing tube 410 in the first instant. After the oil fumes and water mist combine, they flow in the first space 110 and collide with the first collision component 200, liquefying into oil stains, so as to achieve the first step of purification of oil fumes. A number of atomizing holes 411 are arranged along the length of the atomizing tube 410, and the atomizing holes 411 are oriented toward the first air inlet 111 and / or the second air inlet 112. When the oil fumes enter the first space 110 from the first air inlet 111 and / or the second air inlet 112, it is ensured that the water mist released by the atomizing tube 410 can be directly mixed with the oil fumes, thus ensuring the liquefaction effect of the oil fumes.

[0047] like Figure 2 and 8 As shown, the condensation assembly 500 includes a cold ion emitter (not shown) and at least one cold ion emission tube 510; the cold ion emitter is installed inside the housing 100, and the cold ion emission tube 510 is installed inside the first space 110, with the cold ion emission tube 510 facing the confluence port 121; the cold ion emission tube 510 has a first arc surface 511 and a second arc surface 512 opposite to the first arc surface 511, the first arc surface 511 being close to the first air inlet 111, and the second arc surface 512 being close to the second air inlet 112; the first arc surface 511 is provided with a plurality of rows of first emission holes 5111 arranged along the length direction of the cold ion emission tube 510, the first emission holes 5111 facing the first air inlet 111; the second arc surface 512 is provided with a plurality of rows of second emission holes 5121 arranged along the length direction of the cold ion emission tube 510, the second emission holes 5121 facing the second air inlet 112.

[0048] In this embodiment, the cold ion emitter is a commercially available cold ion emitter, 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 510 is connected to the cold ion emitter. The cold ions prepared by the cold ion emitter are emitted into the first space 110 through the cold ion emission tube 510. When the oil fume enters the first space 110, the cold ions emitted into the first space 110 combine with the oil fume to cool it down. When the oil fume flows in the first space 110 and collides with the first collision component 200, the oil fume with lower temperature will liquefy to form oil stains, thereby achieving the second step of purification of the oil fume. The first emission hole 5111 of the first arc surface 511 on the cold ion emission tube 510 faces the first air inlet 111, and the second emission hole 5121 of the second arc surface 512 on the cold ion emission tube 510 faces the second air inlet 112. After the oil fumes enter the first space 110 from the first air inlet 111 and / or the second air inlet 112, they flow towards the confluence port 121. The cold ions emitted from the first emission hole 5111 are directly opposite the oil fumes entering from the first air inlet 111, and the cold ions emitted from the second emission hole 5121 are directly opposite the oil fumes entering from the second air inlet 112, 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.

[0049] like Figure 2 and 9 As shown, the photolysis assembly 600 includes a mounting base 610, a UV lamp 620, and a catalyst bag 630; the mounting base 610 is installed in the second space 120 and is located above the confluence port 121; the mounting base 610 has a mounting cavity 611 and a catalyst cavity 612 arranged around the mounting cavity 611, the UV lamp 620 is installed in the mounting cavity 611, and the catalyst bag 630 is installed in the catalyst cavity 612; a plurality of release holes 613 are provided around the mounting base 610.

[0050] In this embodiment, the catalyst bag 630 can be manganese dioxide. Ozone is generated by irradiation with UV lamp 620. When the oil fume purified by the atomizing component 400 and the condensing component 500 in the first space 110 enters the second space 120 from the confluence port 121, the mounting base 610 is located above the confluence port 121. The ozone generated by UV lamp 620 and catalyst bag 630 is directly mixed with the oil fume entering the second space 120 from the confluence port 121 to remove harmful substances in the oil fume, thereby achieving the third step of purification of the oil fume.

[0051] like Figure 2 and 10As shown, the filter assembly 700 includes a filter cotton plate 710; the filter cotton plate 710 is installed in the third space 130, and the cross-section of the filter cotton plate 710 is serrated so that the filter cotton plate 710 has a plurality of filter channels 711 arranged along its length direction, and the filter channels 711 are all arranged opposite to the first guide port 122, the second guide port 123 and the guide hole 171.

[0052] In this embodiment, the filter cotton plate 710 is made by pressing filter cotton into a plate shape and then folding it to have several filter channels 711 arranged along the length direction. When the oil fume purified by the photolysis component 600 in the second space 120 enters the third space 130 through the guide hole 171 in the middle of the guide plate 170, this part of the oil fume is first filtered and purified by the filter cotton plate 710, while the oil fume containing larger particles enters through the guide holes 171 on both sides of the guide plate 170 or the first guide port 122. Alternatively, the oil fume can enter the third space 130 through the second guide port 123, where the filter cotton plate 710 filters the oil fume to achieve the third step of purification. The filter channel 711 is arranged opposite to the first guide port 122, the second guide port 123, and the guide hole 171. After the oil fume containing larger particles enters the third space 130 through the larger guide holes 171 on both sides of the guide plate 170, or the first guide port 122 or the second guide port 123, it can flow in the filter channel 711, ensuring that all the oil fume can be filtered and purified by the filter cotton plate 710.

[0053] Example 2: like Figure 11 As shown, this embodiment provides a range hood, including a smoke collection hood 20, a purification module 10 as described in Embodiment 1, 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.

[0054] 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 them from spreading into the kitchen space, and collect oil stains. The purification module 10 is located in the middle of the range hood. The fume fumes are purified and filtered through multiple processes by the atomizing component 400, condensing component 500, photolysis component 600, and filter component 700. The oil fumes captured by the fume hood 20 enter the purification module 10 and are purified and filtered by the atomizing component 400, condensing component 500, photolysis component 600, and filter component 700 to form oil fumes that meet emission standards. The fan component is located at the top of the range hood. The fan component provides power for the flow of oil fumes. The fan component draws the oil fumes captured by the fume hood 20 into the purification module for purification and filtration. The purified and filtered oil fumes are then discharged into the atmosphere through the fan component. This range hood, through the purification module 10 in Embodiment 1, 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.
