Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of smoke purification equipment, and particularly relates to an oil fume purification equipment. BACKGROUND

[0002] Oil fume refers to smoke composed of volatile matter, condensate, aerosol, water vapor and fine particulate matter of edible oil and food under high temperature in the process of food cooking and processing. The current range hood can only function to discharge oil fume, and directly discharging oil fume into the outside air will cause environmental pollution and is not environmentally friendly. According to the formation process and component analysis of oil fume, it is concluded that oil fume is a kind of aerosol mixed with gas, liquid and solid phases, and the composition is very complex and changes with different cooking conditions and food materials.

[0003] Therefore, the oil fume generated in cooking must be effectively purified before being discharged into the atmosphere to reduce pollution. The target is mainly aimed at oil particles, solid particles and gaseous pollutants. Due to the characteristics of fierce fire and stir-frying of Chinese cooking, the amount of oil fume is large, and the purification device of the range hood needs to have a longer service life.

[0004] The range hood usually has a smoke collecting hood to collect oil fume, and a fan assembly to suck the oil fume collected by the smoke collecting hood into a purification module. After the oil fume is purified in the purification module, the oil fume is discharged through the fan assembly. The existing purification module of the range hood usually has an air inlet at the bottom, and the oil fume flows upward after entering the purification module from the air inlet and passes through the atomization assembly and the condensation assembly in the purification module to liquefy the oil fume and form oil dirt, so as to avoid discharging the oil dirt into the atmosphere. However, the flow path of the oil fume passing through the atomization assembly and the condensation assembly is vertically upward after the oil fume enters the purification module, the flow path is short, and the atomization assembly and the condensation assembly cannot completely liquefy the oil fume, so that the oil fume discharged into the atmosphere still contains a large amount of oil dirt and harmful substances, causing environmental pollution.

[0032] The atomizing component 220 is installed inside the purification chamber 211 and is located at the first air inlet 2111 and / or the second air inlet 2112. The atomizing component 220 can release water mist. When oil fumes enter the purification chamber 211 from the first air inlet 2111 and / or the second air inlet 2112, the water mist released by the atomizing component 220 and the oil fumes can be fully mixed. During the flow, they violently collide within the purification chamber 211, causing the oil fumes to liquefy into oil stains, thus achieving the purification of oil fumes. The first step of purification involves a condenser assembly 230 installed inside the purification chamber 211, positioned opposite the confluence port 2121. The condenser assembly 230 emits cold ions, which combine with the oil fumes to lower their temperature. As the oil fumes flow through the purification chamber 211, the cooled fumes collide with the inner surface of the chamber, liquefying and forming oil stains, thus achieving the second step of purification. A photolysis assembly 240 is installed inside the photolysis chamber 212. Within the 12th chamber, the photolysis component 240 is located above the confluence port 2121. The photolysis component 240 generates ozone. The oil fumes purified by the atomizing component 220 and the condensing component 230 in the purification chamber 211 enter the photolysis chamber 212 from the confluence port 2121. The photolysis component 240, directly opposite the confluence port 2121, removes harmful substances from the oil fumes entering the photolysis chamber 212 from the confluence port 2121, thus achieving the third step of oil fume purification. The filter component 250 is installed in the filter chamber 212. Within chamber 212, with filter assembly 250 positioned above the first guide port 2122 and the second guide port 2123, the e-liquid purified by photolysis assembly 240 flows towards the first guide port 2122 and the second guide port 2123 on both sides within the photolysis chamber 212. It enters the filter chamber 213 from the first guide port 2122 and / or the second guide port 2123. Filter assembly 250 further filters particulate matter and harmful substances from the oil fumes, achieving a fourth step in the purification of the oil fumes. Through the multiple purification processes of atomizing assembly 220, condensing assembly 230, photolysis assembly 240, and filter assembly 250, the purification effect of the oil fumes is greatly improved, ensuring that the purified oil fumes meet emission standards.

The diverter plate 215 is disposed at the bottom of the main body 214, so that the bottom of the main body 214 has a first air inlet 2111 and a second air inlet 2112. The confluence assembly 216 includes a first confluence plate 2161 and a second confluence plate 2162, both of which are disposed in the middle of the main body 214. A confluence port 2121 is formed between the first confluence plate 2161 and the second confluence plate 2162, and the confluence port 2121 is connected to the first air inlet 2111 and the second air inlet 2112. The air vent 2111 and the second air inlet 2112 are staggered; the guide plate 217 is disposed on the upper part of the main body 214 so that the upper part of the main body 214 has a first guide port 2122 and a second guide port 2123, and the guide plate 217 is opposite to the confluence port 2121; the guide plate 217 is provided with a plurality of rows of guide holes 2171 arranged along the width direction of the main body 214, the plurality of rows of guide holes 2171 are arranged in parallel, the diameter of the guide holes 2171 in the same row is equal, and the diameter of the guide holes 2171 in the middle row gradually increases towards the guide holes 2171 on both sides.

[0034] In this embodiment, the housing structure includes a main body 214, a diverter plate 215, a confluence assembly 216, and a guide plate 217. The main body 214 is an internally connected frame structure. The diverter plate 215 is located at the bottom of the main body 214. Specifically, the diverter plate 215 is located in the middle of the bottom of the main body 214, so that the diverter plate 215 divides the bottom of the main body 214. A first air inlet 2111 and a second air inlet 2112 are formed on both sides of the bottom of the main body 214, allowing oil fumes to enter the interior of the main body 214. The first confluence plate 2161 and the second confluence plate 2162 are both located in the middle of the main body 214. Specifically, the first confluence plate 2161 and the second confluence plate 2162 are located in the middle of the main body 214. On two opposite sides of 214, the first confluence plate 2161 faces the first air inlet 2111, and the second confluence plate 2162 faces the second air inlet 2112. A confluence port 2121 is formed between the first confluence plate 2161 and the second confluence plate 2162. Oil fumes enter the main body 214 from the first air inlet 2111 and the second air inlet 2112 on both sides of the diverter plate 215. Some of the oil fumes entering the main body 214 from the first air inlet 2111 will bounce back due to the first confluence plate 2161 facing the first air inlet 2111. This means that some of the oil fumes will repeatedly bounce and flow between the first confluence plate 2161 and the diverter plate 215 until they reach the confluence port 2121. The fumes flow through the guide holes 2171, first guide port 2122, and second guide port 2123 of the guide plate 217 and are discharged. The fumes repeatedly bounce and flow between the first confluence plate 2161 and the splitter plate 215, flowing into the guide plate 217 in a reverse "S" shape. This significantly increases the flow distance of the fumes. Thus, the atomizing component 220, condensing component 230, photolysis component 240, and filter component 250 installed in the housing 210 can effectively purify and photolyze the fumes, ensuring thorough purification within the housing 210 and that the fumes discharged into the atmosphere meet standards. Similarly, some fumes entering the main body 214 from the second air inlet 2112 are discharged because the second confluence plate 2162 is directly opposite the second air inlet 2112. Plate 2162 has a rebound effect on the oil fumes, meaning that some of the oil fumes will repeatedly bounce and flow between the second confluence plate 2162 and the diversion plate 215 until they flow to the confluence port 2121. From the confluence port 2121, they flow to the guide holes 2171, the first guide port 2122, and the second guide port 2123 of the guide plate 217 and are discharged. The oil fumes will repeatedly bounce and flow between the second confluence plate 2162 and the diversion plate 215 and flow into the guide plate 217. The flow trajectory is "S" shaped, which greatly increases the flow distance of the oil fumes. The atomizing component 220, the condensing component 230, the photolysis component 240, and the filter component 250 can fully purify and photolyze the oil fumes, ensuring that the oil fumes are fully purified in the housing 210 and that the oil fumes discharged into the atmosphere meet the standards.

[0035] The housing 210 uses a diversion plate 215, a merging assembly 216, and a guide plate 217 to make the oil fumes entering the main body 214 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 210. This improves the purification, photolysis, and filtration effect of the oil fumes, ensures that the oil fumes are completely purified in the housing 210, and avoids the pollution of the environment by the discharged oil fumes.

[0036] A row of guide holes 2171 includes several guide holes 2171 with equal diameters. The guide holes 2171 in the same row have equal diameters. The middle row of guide holes 2171 is directly opposite the confluence port 2121, and the diameter of the guide holes 2171 in the middle row gradually increases towards the guide plates 217. Preferably, the diameter of the guide holes 2171 in the middle row is 3 mm, and the diameter of the outermost row of guide holes 2171 is 8 mm. The outermost row of guide holes 2171 is close to the first guide port 2122 or the second guide port 2122. 23; After being purified by the atomizing component 220, the condensing component 230 and the photolysis component 240, the oil fumes containing fine particles flow from the central guide hole 2171 to the filter chamber 213, while the oil fumes containing larger particles enter the filter chamber 213 from the guide holes 2171 on both sides, or the first guide port 2122 or the second guide port 2123. In the filter chamber 213, the oil fumes are then filtered by the filter component 250. This design ensures that the oil fumes are evenly distributed in the filter chamber 213, and that the particles in the oil fumes can be completely filtered by the filter component 250.

[0037] Furthermore, as one embodiment, the main body 214 includes an upper box structure and a lower box structure; the upper box structure is disposed above the lower box structure, the diverter plate 215 is disposed at the bottom of the lower box structure, the confluence assembly 216 is disposed at the bottom of the upper box structure, and the guide plate 217 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 214. The diverter plate 215 is disposed at the bottom of the lower box structure, meaning the first air inlet 2111 and the second air inlet 2112 are located on both sides of the bottom of the lower box structure, and the first air inlet 2111 and the second air inlet 2112 communicate with the interior of the lower box structure. The confluence assembly 216 is disposed at the bottom of the upper box structure, meaning the confluence port 2121 is located at the bottom of the upper box structure, and similarly, the confluence port 2121 is located at the top of the lower box structure, allowing for confluence... The inlet 2121 connects the interior of the lower housing structure with the interior of the upper housing structure. The guide plate 217 is located on the upper part of the upper housing structure, that is, the first guide port 2122 and the second guide port 2123 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 2111 and the second air inlet 2112 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 2171 or the first guide port 2122 or the second guide port 2123 on the guide plate 217.

[0038] Of course, the main body 214 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 214. The main body 214 is a frame structure. The diverter plate 215 is set at the bottom of the frame and forms a first air inlet 2111 and a second air inlet 2112 at the bottom of the frame. The first confluence plate 2161 and the second confluence plate 2162 are set in the middle of the frame and form a confluence port 2121 in the middle of the frame. The guide plate 217 is set in the upper part of the frame and forms a first guide port 2122 and a second guide port 2123 in the upper part of the frame.

[0039] like Figures 6-9As shown, the main body 214, the diverting plate 215, and the confluence assembly 216 enclose the purification chamber 211; the main body 214, the confluence assembly 215, and the guide plate 217 enclose the photolysis chamber 212; and the main body 214 and the guide plate 217 enclose the filtration chamber 213. The main body 214 has a first side 2141 and a second side 2142 opposite to the first side 2141. The first air inlet 2111 is close to the first side 2141, and the second air inlet 2112 is close to the second side 2142. The first confluence plate 2161 is close to the first side 2141, and the second confluence plate 2162 is close to the second side 2142. The first guide port 2122 is close to the first side 2141, and the second air inlet 2111 is close to the first side 2142. Two guide ports 2123 are located near the second side 2142; when oil fumes enter the housing 210 from the fume collection hood 10, the oil fumes enter the purification chamber 211 from the first air inlet 2111, flow along the purification chamber 211 toward the confluence port 2121, and enter the photolysis chamber 212, so that the oil fumes enter the filter chamber 213 from the guide hole 2171 or the first guide port 2122 or the second guide port 2123 of the guide plate 217; and / or, oil fumes enter the purification chamber 211 from the second air inlet 2112, flow along the purification chamber 211 toward the confluence port 2121, and enter the photolysis chamber 212, so that the oil fumes enter the filter chamber 213 from the guide hole 2171 or the first guide port 2122 or the second guide port 2123 of the guide plate 217.

[0040] In this embodiment, the main body 214, the diverter plate 215, and the confluence assembly 216 enclose a purification chamber 211. As one embodiment, the interior of the lower housing structure is the purification chamber 211, and the main body 214, the confluence assembly 216, and the guide plate 217 enclose a photolysis chamber 212. As another embodiment, the interior of the upper housing structure is the photolysis chamber 212, and the main body 214 and the guide plate 217 enclose a filter chamber 213, that is, a filter chamber 213 is formed above the upper housing structure. The main body 214 has a first side 2141 and a second side 2142 arranged opposite to each other. The first air inlet 2111 is close to the first side 2141, the second air inlet 2112 is close to the second side 2142, the first confluence plate 2161 is close to the first side 2141, the second confluence plate 2162 is close to the second side 2142, the first guide port 2122 is close to the first side 2141, and the second guide port 2123 is close to the second side 2142. Through this design, the oil fumes entering the main body 214 from the first air inlet 2111 flow sequentially through the purification chamber 211, the confluence port 2121, and the photolysis chamber 212. The flow path of the oil fumes entering the main body 214 from the second air inlet 2112 is reversed "S" shaped. The oil fumes flow through the purification chamber 211, the confluence port 2121, the photolysis chamber 212, the flow path of the guide plate 217, and the filter chamber 213 in sequence, and the flow path of the guide plate 217 is reversed "S". In this way, by optimizing the flow path of the oil fumes in the main body 214, the purification, photolysis and filtration effects of the oil fumes are improved, and the oil fumes are completely purified in the purification chamber.

[0041] like Figure 10 As shown, in the housing 210, a rectangular coordinate system is constructed with the center of the diverter plate 215 as the origin O. The first point of the diverter plate 215 is A1, the second point of the diverter plate 215 is A2, the first point of the first air inlet 2111 is B1, the second point of the second air inlet 2112 is B2, the first point of the second air inlet 2112 is C1, the second point of the second air inlet 2112 is C2, and the first point A1 of the diverter plate 215 coincides with the second point B2 of the first air inlet 2111. The second point A2 of the flow divider 215 coincides with the first point C1 of the second air inlet 2112; wherein, the distance from the first point A1 of the flow divider 215 to the second point A2 of the flow divider 215 is d1, 70cm≤d1≤74cm; the distance from the first point B1 of the first air inlet 2111 to the first point B2 of the first air inlet 2111 is i1, and the distance from the first point C1 of the second air inlet 2112 to the first point C2 of the second air inlet 2112 is i2, 13cm≤i1=i2≤17cm.

[0042] The distance from the first point A1 to the second point A2 of the diverter plate 215 is d1, that is, the width of the diverter plate 215 is d1, 70cm≤d1≤74cm, preferably, the width of the diverter plate 215 is 72cm. The distance from the first point B1 to the first point B2 of the first air inlet 2111 is i1, and the distance from the first point C1 to the first point C2 of the second air inlet 2112 is i2, that is, the distance from the first point B1 to the second point C2 of the second air inlet 2112 is i2. The width of the first air inlet 2111 is i1, the width of the second air inlet 2112 is i2, and the widths of the first air inlet 2111 and the second air inlet 2112 are equal, within the range of 13cm-17cm. Preferably, the widths of the first air inlet 2111 and the second air inlet 2112 are 15cm. With this setting, on the one hand, the size of the cabinet 210 is avoided from being too large and occupying too much space in the kitchen, and on the other hand, the air volume and air speed of the first air inlet 2111 and the second air inlet 2112 are guaranteed.

[0043] like Figure 10 As shown, the first point of the first merging plate 2161 is D1, the second point of the first merging plate 2161 is D2, the first point of the second merging plate 2162 is E1, the second point of the second merging plate 2162 is E2, the first point of the merging port 2121 is F1, the second point of the merging port 2121 is F2, the first point F1 of the merging port 2121 coincides with the second point D2 of the first merging plate 2161, and the second point F2 of the merging port 2121 coincides with the first point E1 of the second merging plate 2162; wherein, the distance from the first point D1 of the first merging plate 2161 to the first... The distance from the second point D2 of the merging plate 2161 is d2, and the distance from the first point E1 of the second merging plate 2162 to the second point E2 of the second merging plate 2162 is d3, 34cm≤d2=d3≤38cm; the distance from the first point F1 of the merging port 2121 to the second point F2 of the merging port 2121 is i3, 28cm≤i3≤32cm; the distance from the first point D1 of the first merging plate 2161 to the splitting plate 215 is h1, and the distance from the second point E1 of the second merging plate 2162 to the splitting plate 215 is h2, 13cm≤h1=h2≤17cm.

[0044] The distance from the first point D1 of the first merging plate 2161 to the second point D2 of the first merging plate 2161 is d2, and the distance from the first point E1 of the second merging plate 2162 to the second point E2 of the second merging plate 2162 is d3. 34cm ≤ d2 = d3 ≤ 38cm, meaning the width of the first merging plate 2161 and the width of the second merging plate 2162 are equal. Preferably, the width of the first merging plate 2161 and the second merging plate 2162 is 36cm; the first point of the merging port 2121... The distance from F1 to the second point F2 of the confluence port 2121 is i3, where 28cm ≤ i3 ≤ 32cm, meaning the width of the confluence port 2121 is i3. Preferably, the width of the confluence port 2121 is 30cm. The distance from the first point D1 of the first confluence plate 2161 to the diverter plate 215 is h1, and the distance from the second point E1 of the second confluence plate 2162 to the diverter plate 215 is h2, where 13cm ≤ h1 = h2 ≤ 17cm. Preferably, the height of the purification chamber 211 is h1 or h2. The height of the purification chamber 211 is 15cm. This design ensures that, on the one hand, the first confluence plate 2161 completely blocks the first air inlet 2111, and causes the fumes entering the purification chamber 211 from the first air inlet 2111 to bounce back and flow between the first confluence plate 2161 and the diverter plate 215 to the confluence port 2121. Similarly, the second confluence plate 2162 completely blocks the second air inlet 2112, and causes the fumes entering the purification chamber 211 from the second air inlet 2112 to... The oil fumes bounce off between the second confluence plate 2162 and the diverter plate 215 and flow to the confluence port 2121. On the other hand, the width of the confluence port 2121 is twice that of the first air inlet 2111 or the second air inlet 2112, ensuring that the oil fumes entering from the first air inlet 2111 and / or the second air inlet 2112 can receive the oil fumes flowing in from the first air inlet 2111 and / or the second air inlet 2112 after they flow to the confluence port 2121, thus preventing the oil fumes from lingering in the purification chamber 211.

[0045] like Figure 10As shown, the first point of the guide plate 217 is G1, the second point of the guide plate 217 is G2, the first point of the first guide port 2122 is H1, the second point of the first guide port 2122 is H2, the first point of the second guide port 2123 is I1, and the second point of the second guide port 2123 is I2. The first point G1 of the guide plate 217 coincides with the second point H2 of the first guide port 2122, and the second point G2 of the guide plate 217 coincides with the first point I1 of the second guide port 2123. The distance from the first point G1 of the guide plate 217 to the first confluence plate 2161 is h3, and the distance from the second point G2 of the guide plate 217 to the second confluence plate 2162 is h4. 10cm ≤ h3 = h4 ≤ 15cm, and h3 = h4. i1=i2. The distance from the first point G1 of the guide plate 217 to the top of the main body 214 is h5, and the distance from the second point G2 of the guide plate 217 to the top of the main body 214 is h6. 8cm≤h5=h6≤12cm, and h5=h6 <h3=h4。 <h1>

[0046] The distance from the first point G1 of the guide plate 217400 to the first confluence plate 2161 is h3, and the distance from the second point G2 of the guide plate 217 to the second confluence plate 2162 is h4. 10cm ≤ h3 = h4 ≤ 15cm, meaning the height of the photolysis cavity 212 is h3 or h4. Preferably, the height of the photolysis cavity 212 is 12cm, and h3 = h4. i1=i2, that is, the widths of the first guide port 2122 and the second guide port 2123 are equal. Preferably, the widths of the first guide port 2122 and the second guide port 2123 are 16cm. With this design, the oil fumes in the photolysis chamber 212 can all flow to the filter chamber 213 through the guide holes 2171 on the guide plate 217, so as to avoid the oil fumes from being retained in the photolysis chamber 212.<h1>

[0047] like Figure 10As shown, the distance from the first point G1 of the guide plate 217 to the top of the main body 214 is h5, and the distance from the second point G2 of the guide plate 217 to the top of the main body 214 is h6. 8cm ≤ h5 = h6 ≤ 12cm, and h5 = h6. <h3=h4。

[0048] The distance from the first point G1 of the guide plate 217 to the top of the main body 214 is h5, and the distance from the second point G2 of the guide plate 217 to the top of the main body 214 is h6. 8cm≤h5=h6≤12cm, meaning the height of the filter chamber 213 is h5 or h6. Preferably, the height of the filter chamber 213 is 10cm. The height of the filter chamber 213 is less than the height of the photolysis chamber 212, and the height of the photolysis chamber 212 is less than the height of the purification chamber 211. When this housing 210 is used to purify oil fumes, the oil fumes enter the purification chamber 211 from the first air inlet 2111 and the second air inlet 2112. The atomizing component 220 and the condensing component 230 perform the first and second steps of purification on the oil fumes. The fumes then enter the photolysis chamber 212 from the confluence port 2121. After the photolysis component 240 performs the third step of purification on the oil fumes, they enter the purification chamber 212 through the first guide port 2122 or the second guide port 2123 or the guide port. The oil fumes enter the filter chamber 213, where the filter assembly 250 performs the fourth step of purification. Since the oil fumes and oil stains are most concentrated in the purification chamber 211, the height of the purification chamber 211 is relatively higher than that of the photolysis chamber 212 and the filter chamber 213. This ensures that the oil fumes are fully purified in the purification chamber 211 first. After being purified by the atomizing assembly 220 and the condensing assembly 230 in the purification chamber 211, the oil stains are reduced. Therefore, the height of the photolysis chamber 212 can be slightly smaller than that of the purification chamber 211. The photolysis assembly 240 in the photolysis chamber 212 can fully purify the oil fumes. Similarly, after being purified by the photolysis assembly 240 in the photolysis chamber 212, the oil stains and harmful substances are further reduced. The height of the filter chamber 213 can be slightly smaller than that of the photolysis chamber 212. Thus, the thickness of the filter assembly 250 in the filter chamber 213 can be slightly smaller to completely filter and purify the oil fumes. The housing 210 is designed such that the height of the filter chamber 213 is less than the height of the photolysis chamber 212, and the height of the photolysis chamber 212 is less than the height of the purification chamber 211. On the one hand, this ensures a reasonable internal structure arrangement of the main body 214, optimizes the flow path of oil fumes within the main body 214, and improves the purification effect of oil fumes. On the other hand, it effectively reduces the thickness of the filter component 250 in the filter chamber 213, greatly saving costs.

[0049] like Figure 6 , 11As shown in Figure 12, the atomizing assembly 220 includes an atomizer (not shown) and at least one atomizing tube 221; the atomizer is installed inside the housing 210, and the atomizing tube 221 is installed inside the purification chamber 211, with the atomizing tube 221 located at the first air inlet 2111 and / or the second air inlet 2112; a plurality of atomizing holes 2211 are evenly arranged on the atomizing tube 221, the plurality of atomizing holes 2211 being arranged along the length of the atomizing tube 221, and the direction of the atomizing holes 2211 facing the first air inlet 2111 and / or the second air inlet 2112; the condensation assembly 230 includes a cold ion emitter (not shown) and at least one cold ion emission tube 231; the cold ion emitter is installed inside the housing 210, and the cold ion emission tube 231 is installed inside the purification chamber 211. Inside the purification chamber 211, the cold ion emission tube 231 is disposed opposite to the confluence port 2121; the cold ion emission tube 231 has a first arc surface 2311 and a second arc surface 2312 opposite to the first arc surface 2311. The first arc surface 2311 is close to the first air inlet 2111, and the second arc surface 2312 is close to the second air inlet 2112. The first arc surface 2311 is provided with a plurality of rows of first emission holes 23111 arranged along the length direction of the cold ion emission tube 231, and the first emission holes 23111 face the first air inlet 2111. The second arc surface 2312 is provided with a plurality of rows of second emission holes 23121 arranged along the length direction of the cold ion emission tube 231, and the second emission holes 23121 face the second air inlet 2112.

[0050] 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 221 is connected to the mist outlet of the atomizer. The water mist produced by the atomizer can be released into the purification chamber 211 through the atomizing tube 221. Specifically, the atomizing tube 221 is set at the first air inlet 2111 or the second air inlet 2112. Preferably, both the first air inlet 2111 and the second air inlet 2112 are provided with atomizing tubes 221. When the oil fumes enter the purification chamber 211 from the first air inlet 2111 and the second air inlet 2112, they combine with the water mist released from the atomizing tube 221 immediately. After the oil fumes and water mist combine, they flow and collide in the purification chamber 211, liquefying into oil stains, so as to achieve the first step of purification of oil fumes. A number of atomizing holes 2211 are arranged along the length of the atomizing tube 221, and the atomizing holes 2211 are oriented toward the first air inlet 2111 and / or the second air inlet 2112. When the oil fumes enter the purification chamber 211 from the first air inlet 2111 and / or the second air inlet 2112, it is ensured that the water mist released by the atomizing tube 221 can be directly mixed with the oil fumes, thus ensuring the liquefaction effect of the oil fumes.

[0051] The cold ion emitter is a common type of cold ion emitter on the market and is an existing technology. It can emit ions with low temperature. Its structure and principle will not be described in detail here. The cold ion emission tube 231 is connected to the cold ion emitter. The cold ions prepared by the cold ion emitter are emitted into the purification chamber 211 through the cold ion emission tube 231. When the oil fume enters the purification chamber 211, the cold ions emitted into the purification chamber 211 combine with the oil fume to cool it down. When the oil fume flows and collides in the purification chamber 211, the oil fume with lower temperature will liquefy to form oil stains, thus achieving the second step of purification of the oil fume. The first emission hole 23111 of the first arc surface 2311 on the cold ion emission tube 231 faces the first air inlet 2111, and the second emission hole 23121 of the second arc surface 2312 on the cold ion emission tube 231 faces the second air inlet 2112. After the oil fumes enter the purification chamber 211 from the first air inlet 2111 and / or the second air inlet 2112, they flow towards the confluence port 2121. The cold ions emitted from the first emission hole 23111 are directly opposite to the oil fumes entering from the first air inlet 2111, and the cold ions emitted from the second emission hole 23121 are directly opposite to the oil fumes entering from the second air inlet 2112, 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.

[0052] like Figure 6 and 13 As shown, the photolysis assembly 240 includes a mounting base 241, a UV lamp 242, and a catalyst bag 243. The mounting base 241 is located within the photolysis chamber 212. The mounting base 241 has a mounting cavity 2411 and a catalyst chamber 2412 arranged around the mounting cavity 2411. A plurality of release holes 2413 are provided around the mounting base 241. The UV lamp 242 is mounted within the mounting cavity 2411. The catalyst bag 243 is mounted within the catalyst chamber 2412. The cross-section of the mounting cavity 2411 is... The mounting cavity 2411 has a rhomboid shape. In the cross-sectional outline of the mounting cavity 2411, the mounting cavity 2411 has four end-to-end connected edges and a first end point 24111 and a second end point 24112 arranged opposite to each other. A catalytic cavity 2412 is formed on each of the four edges away from the mounting cavity 2411. A catalytic cavity 2412 is also formed on the first end point 24111 and the second end point 24112 away from the mounting cavity 2411, so that catalytic cavities 2412 are arranged on the periphery of the mounting cavity 2411.

[0053] In this embodiment, the mounting base 241 has a mounting cavity 2411 and a catalyst cavity 2412 arranged around the mounting cavity 2411. A plurality of release holes 2413 are provided around the mounting base 241. A UV lamp 242 is installed inside the mounting cavity 2411, and a catalyst bag 243 is installed inside the catalyst cavity 2412. When the photolysis assembly 240 is working, the UV lamp 242 is turned on, emitting ultraviolet light into the surrounding catalyst cavity 2412 to irradiate the catalyst bag 243, causing O2 molecules to decompose into oxygen atoms (O) inside the photolysis cavity 2412. The oxygen atoms combine with O2 to generate ozone, thus filling the photolysis cavity 2412 with ozone. After being purified by the atomizing component 220 and the condensing component 230, the oil fumes enter the photolysis chamber 212. Ozone and oil fumes fully combine within the photolysis chamber 212, effectively removing harmful substances from the fumes and ensuring that the fumes emitted into the atmosphere are free of harmful substances, thus avoiding environmental pollution. Furthermore, catalytic chambers 2412 are arranged around the mounting chamber 2411, and catalyst bags 243 are installed within each catalytic chamber 2412. This significantly improves the ozone production effect, ensuring the ozone content within the photolysis chamber 212, and consequently ensuring the effectiveness of the photolysis component 240 in removing harmful substances from the oil fumes. As one embodiment, the catalyst bag 243 can be manganese dioxide, which provides a good catalytic effect.

[0054] like Figure 14 As shown, the cross-sectional profile of the mounting cavity 2411 is rhomboid. This rhomboid shape facilitates the UV lamp 242's emission of ultraviolet light in all directions. A catalytic cavity 2412 is formed on each of the four edges away from the mounting cavity 2411. The left and right sides of the mounting cavity 2411 have a first endpoint 24111 and a second endpoint 24112. Similarly, a catalytic cavity 2412 is formed on each of the first and second endpoints away from the mounting cavity 2411. Thus, there are six catalytic cavities 2412. The installation cavity 2411 is surrounded by a UV lamp 242. The ultraviolet light emitted by the UV lamp 242 inside the installation cavity 2411 can diffuse to the catalytic cavity 2412 on the outer periphery of the installation cavity 2411. A catalyst bag 243 is then installed inside the catalytic cavity 2412. In this way, the ozone preparation effect can be greatly improved. Of course, the number of catalytic cavities 2412 can be adjusted according to the actual situation. More than six or less are both acceptable. The cross-sectional outline of the installation cavity 2411 can also be other shapes, such as circles or regular polygons, as long as it can ensure that the ultraviolet light emitted by the UV lamp 242 can diffuse evenly in all directions.

[0055] like Figure 14As shown, as an embodiment, the cross-sectional profile of the mounting base 241 is an inverted trapezoid. The upper side length of the mounting base 241 is w1, where 38 cm ≤ w1 ≤ 42 cm. The lower side length of the mounting base 241 is w2, where 28 cm ≤ w2 ≤ 32 cm. The height of the mounting base 241 is j, where 10 cm ≤ j ≤ 14 cm. A number of light-transmitting holes 2414 are provided on the peripheral side of the mounting cavity 2411. The diameter of the light-transmitting hole 2414 is r1, and the diameter of the release hole 2413 is r2. The diameter r1 of the light-transmitting hole 2414 and the diameter r2 of the release hole 2413 satisfy: r1 < r2, where r1 ≤ 50 μm and r2 ≤ 100 μm. The material of the mounting base 241 is a foam titanium plate. The plate thickness of the mounting cavity 2411 is b1, and the plate thickness of the catalytic cavity 2412 is b2. The plate thickness b1 of the mounting cavity 2411 and the plate thickness b2 of the catalytic cavity 2412 satisfy: b1 < b2, where b1 ≤ 8 mm and b2 ≤ 10 mm. The cross-sectional profile of the mounting base 241 is an inverted trapezoid, and the upper side length w1 is greater than the lower side length w2. Preferably, the upper side length w1 is equal to 40 cm, the lower side length w2 is equal to 30 cm, and the height j is equal to 12 cm. With such a design, when the photolysis component 240 prepares ozone, it is convenient for the prepared ozone to diffuse to both sides of the photolysis chamber 212, so as to improve the effect of removing harmful substances in the oil fume. A number of light-transmitting holes are provided on the peripheral side of the mounting cavity 2411 to ensure that the ultraviolet rays emitted by the UV lamp 242 can irradiate the surrounding catalytic cavity 2412 through the light-transmitting holes. The diameter r1 of the light-transmitting hole is less than the diameter r2 of the release hole 2413, and r1 ≤ 50 μm and r2 ≤ 100 μm. With such a design, the uniformity of the ultraviolet rays emitted by the UV lamp 242 to the surrounding is ensured, and after the ozone is generated, it can smoothly diffuse to the photolysis chamber 212 through the release hole 2413; and it can effectively avoid the oil fume from polluting the UV lamp 242. The material of the mounting base 241 is a foam titanium plate, and the edge of the mounting base 241 is edged with sheet metal. The foam titanium plate has good chemical stability, and the plate thickness b1 of the mounting cavity 2411 is less than the plate thickness b2 of the catalytic cavity 2412, where b1 ≤ 8 mm and b2 ≤ 10 mm. While ensuring the overall structural strength of the mounting base 241, it will not occupy too much space in the photolysis chamber 212, and thus can avoid the purification module 20 from being too large in volume and occupying too much kitchen space.

[0056] As Figure 6 and 15As shown, the filter assembly 250 includes a filter cotton plate 251; the filter cotton plate 251 is installed in the filter chamber 213, and the cross-section of the filter cotton plate 251 is serrated so that the filter cotton plate 251 has a plurality of filter channels 2511 in its width direction. The filter channels 2511 extend through the length direction of the filter cotton plate 251, and the filter channels 2511 are arranged opposite to the guide hole 2171 and / or the first guide port 2122 and / or the second guide port 2123.

[0057] In this embodiment, the filter cotton plate 251 has several filter channels 2511 along its width. These filter channels 2511 are positioned opposite to the guide holes 2171, the first guide port 2122, and the second guide port 2123. The filter channels 2511 extend through the length of the filter panel, meaning that different columns of guide ports communicate with the filter channels 2511. When the oil fumes purified by the atomizing component 220, the condensing component 230, and the photolysis component 240 within the purification module 20 enter different filter channels 2511 through different columns of guide holes 2171, the first guide port 2122, or the second guide port 2123, the oil fumes can flow within the filter channels 2511. Thus, the filter cotton plate 251 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 251 is made by pressing filter cotton into a plate shape and then folding it to have several filter channels 2511 arranged along its width.

[0058] like Figure 6 As shown, the purification module 20 further includes a first collision component 260 and a second collision component 270; the first collision component is installed in the purification chamber 211, and the first collision component 260 includes a plurality of metal wire meshes stacked along the height direction of the purification chamber 211; the second collision component 270 is installed in the photolysis chamber 212, and the second collision component 270 includes a plurality of metal wire meshes stacked along the length direction of the photolysis chamber 212.

[0059] In this embodiment, the metal mesh of the first collision component 260 is stacked in the purification chamber 211 along the height direction. After the oil fumes enter the purification chamber 211 from the first air inlet 2111 and the second air inlet 2112, they flow towards the confluence port 2121. 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 220 and the condensing component 230, the oil fumes combine with the water mist and cold ions and then violently collide with the first collision component 260. During the violent collision process, the oil fumes liquefy into oil stains on the metal mesh of the first collision component 260, which greatly improves the liquefaction effect of the oil fumes. The metal mesh of the second collision component 270 is stacked along the length of the photolysis chamber 212. As the oil fumes flow towards both sides of the confluence port 2121, when the oil fumes flow from the confluence port 2121 towards the first guide port 2122 or the second guide port 2123 on the upper sides of the photolysis chamber 212, or towards the guide holes 2171 on both sides of the guide plate 217, 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 260 and the second collision component 270, the purification effect of the oil fumes is greatly improved.

[0060] like Figure 1 and 2 As shown, the fan assembly 30 includes at least one fan 310, which is located above the filter assembly 250.

[0061] In this embodiment, the fan assembly 30 includes at least one fan 310. Preferably, the fan 310 is a turbine fan. Turbine fans have the advantages of high efficiency and energy saving, compact structure and strong applicability, and provide power for the fume hood 10 to capture and collect oil fumes, for the oil fumes to flow in the purification module 20 and for the emission of purified oil fumes.
