Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an air conditioning fresh air sterilization and deodorization device. Background Technology

[0002] Both air conditioning and fresh air systems need to bring outside air into the room. To ensure the purity of the incoming air, germicidal lamps are usually installed in air conditioning and fresh air systems to sterilize and deodorize the air.

[0003] For example, the integrated fresh air conditioner proposed in the invention application with application number CN202111495888.7, through the cooperation of filter plate, collection chamber, spring, cam and ultraviolet lamp, can achieve sterilization and dust filtration of fresh air while completing the unified collection and treatment of dust.

[0004] However, the ultraviolet light coverage area of ​​ultraviolet lamps is small, and the sterilization and deodorization range is limited. At the same time, because air passes directly through the ultraviolet light coverage area, the sterilization and deodorization time is short and the sterilization and deodorization effect is poor. Summary of the Invention

[0005] In view of this, it is necessary to provide an air conditioning fresh air sterilization and deodorization device to solve the problems of small ultraviolet coverage area and limited sterilization and deodorization range of ultraviolet lamps, as well as short sterilization and deodorization time and poor sterilization and deodorization effect due to the air directly passing through the ultraviolet coverage area.

[0006] This invention provides an air conditioning fresh air sterilization and deodorization device, including a housing, a flow guiding component, and a sterilization component. The housing has an air inlet on one side and an air outlet on the other side. The flow guiding component includes a flow distribution box, two first baffle plates, and a second baffle plate. The flow distribution box is fixedly disposed within the housing and faces the air inlet. The flow distribution box divides the interior of the housing into two flow distribution channels staggered from the air inlet. The two first baffle plates are respectively disposed in the two flow distribution channels, and the second baffle plate is disposed at the air outlet. The sterilization component is built into the housing, and the ultraviolet light emitted by the sterilization component covers the two flow distribution channels.

[0007] Furthermore, a V-shaped surface is formed on the side of the distribution box near the air inlet, and the V-shaped surface gradually expands in the direction away from the air inlet, with two distribution channels formed on both sides of the V-shaped surface.

[0008] Furthermore, the diversion box includes a V-shaped plate, two side plates, and a rear plate arranged sequentially along the direction from the air inlet to the air outlet. The top and bottom of the V-shaped plate are fixedly connected to the inner wall of the outer casing. The V-shaped plate gradually widens in the direction away from the air inlet. The two sides of the V-shaped plate are fixedly connected to the two side plates respectively. The top and bottom of the two side plates are fixedly connected to the inner wall of the outer casing. The side of the two side plates away from the V-shaped plate is fixedly connected to the two sides of the rear plate respectively. The top and bottom of the rear plate are fixedly connected to the inner wall of the outer casing. The opposite sides of the two first baffle plates are fixedly connected to the inner wall of the outer casing. The opposite sides of the two first baffle plates are fixedly connected to the connection between the V-shaped plate and the two side plates respectively.

[0009] Furthermore, two first turbulence cavities are formed between the two first turbulence perforated plates near the air inlet, between the V-shaped plate and the inner wall of the outer shell, and on both sides of the air inlet. A direct illumination cavity is formed between the two first turbulence perforated plates away from the air inlet, between the two side plates and the inner wall of the outer shell. A second turbulence cavity is formed between the second turbulence perforated plate, the rear plate and the inner wall of the outer shell. The first turbulence cavity, the direct illumination cavity and the second turbulence cavity are sequentially connected to form the diversion channel.

[0010] Furthermore, the two side panels are arranged parallel to each other, and the rear panel is arranged perpendicular to the direction from the air inlet to the air outlet.

[0011] Furthermore, the second flow-deflecting plate has multiple through holes, and the size of the through holes on the second flow-deflecting plate gradually decreases from its central position to both sides.

[0012] Furthermore, the second perforated plate is arranged perpendicular to the direction from the air inlet to the air outlet.

[0013] Furthermore, a reflective layer is provided on the outer wall of the diversion box near the diversion channel.

[0014] Furthermore, the sterilization component includes multiple sterilization lamp groups, which are arranged sequentially on the inner walls of both sides of the housing in the direction from the air inlet to the air outlet.

[0015] Furthermore, the germicidal lamp assembly includes a circuit board and a plurality of germicidal lamps arranged sequentially in a vertical direction, and the plurality of germicidal lamps are electrically connected to the circuit board.

[0016] Compared with existing technologies, by using a diversion box fixed in the outer casing and facing the air inlet, the straight flow direction of the airflow from the air inlet to the air outlet is changed to a bent flow direction along the two diversion channels on both sides. Through the first baffle plate set in the diversion channel, the airflow introduced from the air inlet is obliquely blown towards the first baffle plate. A portion of the airflow passes through the first baffle plate, while the remaining airflow is blown along the oblique direction towards the non-perforated areas of the first baffle plate and flows against the first baffle plate to the inner wall of the outer casing, forming turbulence, thereby prolonging the airflow's passage through the outer casing. During this time, the airflow passing through the first baffle plate is blown along the diversion channel to the second baffle plate. Part of the airflow passes through the second baffle plate and is discharged from the air outlet, while the rest of the airflow blows into the non-perforated areas of the second baffle plate, thus forming turbulence in opposite directions or at an angle. This further prolongs the time the airflow passes through the outer shell, thereby improving the bactericidal and deodorizing effect of the sterilization component on the airflow. At the same time, the ultraviolet light emitted by the sterilization component covers both diversion channels, and the large ultraviolet coverage area further enhances the bactericidal and deodorizing effect.

[0022] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figure 1As shown, the present invention provides an air conditioning fresh air sterilization and deodorization device, including a housing 100, a flow guiding component 200, and a sterilization component 300. The housing 100 has an air inlet 110 on one side and an air outlet 120 on the other side. The flow guiding component 200 includes a diversion box 210, two first baffle plates 220, and a second baffle plate 230. The diversion box 210 is fixedly disposed in the housing 100 and is positioned directly opposite the air inlet 110. The diversion box 210 divides the interior of the housing 100 into two diversion channels 240 that are staggered from the air inlet 110. The two first baffle plates 220 are respectively disposed in the two diversion channels 240, and the second baffle plate 230 is disposed at the air outlet 120. The sterilization component 300 is built into the housing 100, and the ultraviolet light emitted by the sterilization component 300 covers the two diversion channels 240.

[0024] In practice, by fixing a diversion box 210 in the outer casing 100 and facing the air inlet 110, the straight flow direction of the airflow from the air inlet 110 to the air outlet 120 is changed to a bent flow direction along the two diversion channels 240 on both sides. Through the first turbulence perforated plate 220 set in the diversion channel 240, the airflow introduced from the air inlet 110 is blown obliquely towards the first turbulence perforated plate 220. A part of the airflow passes through the first turbulence perforated plate 220, and the rest of the airflow is blown along the oblique direction towards the non-perforated part of the first turbulence perforated plate 220, and flows against the first turbulence perforated plate 220 to the inner wall of the outer casing 100 to form turbulence, thereby prolonging the airflow through the outer casing. During the 100-second interval, the airflow passing through the first baffle plate 220 is blown along the diversion channel 240 to the second baffle plate 230. Part of the airflow passes through the second baffle plate 230 and is discharged from the air outlet 120, while the remaining airflow blows onto the non-perforated areas of the second baffle plate 230, thus forming a turbulence with opposite or inclined directions. This further prolongs the time the airflow passes through the outer casing 100. By prolonging the time the airflow passes through the outer casing 100, the bactericidal and deodorizing effect of the bactericidal component 300 on the airflow is improved. At the same time, the ultraviolet light emitted by the bactericidal component 300 covers both diversion channels 240, and the ultraviolet coverage area is large, which improves the bactericidal and deodorizing effect.

[0025] like Figure 5 As shown, in this embodiment, the housing 100 is installed inside the duct of an air conditioning or fresh air system. Specifically, an air inlet 110 is formed on one side of the housing 100, and an air outlet 120 is formed on the other side. As airflow enters the housing 100 through the air inlet 110 and exits through the air outlet 120, the sterilization component 300 in the housing 100 sterilizes and deodorizes the air.

[0026] In this embodiment, the outer shell 100 adopts a box-type structure, i.e., a cuboid structure. Of course, in other embodiments, a cube or an arc-shaped cylinder may also be used. The shape of the outer shell 100 is not limited in this embodiment of the invention, as long as it can be adapted to the internal shape of the pipe.

[0027] In this embodiment, the airflow guiding component 200 defines the airflow path within the housing 100 to increase the airflow time within the housing 100. The airflow guiding component 200 includes a flow divider box 210, two first baffle plates 220, and a second baffle plate 230. The flow divider box 210 is fixedly disposed within the housing 100 and directly opposite the air inlet 110. The flow divider box 210 divides the interior of the housing 100 into two flow channels 240 that are staggered from the air inlet 110. The two first baffle plates 220 are respectively disposed in the two flow channels 240, and the second baffle plate 230 is disposed at the air outlet 120.

[0028] In order to smoothly guide the airflow entering the housing 100 from the air inlet 110 into the two diversion channels 240, in one embodiment, a V-shaped surface 211 is formed on the side of the diversion box 210 near the air inlet 110. The V-shaped surface 211 gradually expands in the direction away from the air inlet 110, and the two diversion channels 240 are formed on both sides of the V-shaped surface 211.

[0029] In other embodiments, the side of the diversion box 210 near the air inlet 110 can also form an arc-shaped surface, which gradually expands away from the air inlet 110, and two diversion channels 240 are formed on both sides of the arc-shaped surface. Of course, the side of the diversion box 210 near the air inlet 110 can also adopt other shapes. This embodiment of the invention does not limit this, as long as the airflow introduced by the air inlet 110 smoothly transitions into the two diversion channels 240 and is perpendicular to the first turbulence hole group in the inclined direction.

[0030] like Figure 2 As shown, the diversion box 210 in this embodiment includes a V-shaped plate 212, two side plates 213, and a rear plate 214 arranged sequentially along the direction from the air inlet 110 to the air outlet 120. The top and bottom of the V-shaped plate 212 are fixedly connected to the inner wall of the outer shell 100. The V-shaped plate 212 gradually expands in the direction away from the air inlet 110. The two sides of the V-shaped plate 212 are fixedly connected to the two side plates 213 respectively. The top and bottom of the two side plates 213 are fixedly connected to the inner wall of the outer shell 100. The side of the two side plates 213 away from the V-shaped plate 212 is fixedly connected to the two sides of the rear plate 214 respectively. The top and bottom of the rear plate 214 are fixedly connected to the inner wall of the outer shell 100. The opposite sides of the two first turbulence perforated plates 220 are fixedly connected to the inner wall of the outer shell 100. The opposite sides of the two first turbulence perforated plates 220 are fixedly connected to the connection between the V-shaped plate 212 and the two side plates 213 respectively.

[0031] Among them, two first turbulence perforated plates 220 are formed on the side of the air inlet 110, between the V-shaped plate 212 and the inner wall of the outer shell 100, forming two first turbulence cavities 241 respectively on both sides of the air inlet 110; two first turbulence perforated plates 220 are formed on the side of the air inlet 110, between the two side plates 213 and the inner wall of the outer shell 100, forming a direct illumination cavity 242; and a second turbulence cavity 243 is formed between the second turbulence perforated plate 230, the rear plate 214 and the inner wall of the outer shell 100. The first turbulence cavity 241, the direct illumination cavity 242 and the second turbulence cavity 243 are connected in sequence to form a diversion channel 240.

[0032] In one embodiment, the two side panels 213 are arranged parallel to each other, and the rear panel 214 is arranged perpendicular to the air inlet 110 and pointing towards the air outlet 120. Of course, the two side panels 213 can also be arranged at an angle, which does not affect the implementation of the embodiment of the present invention.

[0033] like Figure 3 As shown, it can be understood that the first baffle plate 220 is a flat plate with multiple through holes evenly arranged on it. The size of the multiple through holes can be the same or different, and this embodiment of the invention does not limit this. When the airflow introduced by the air inlet 110 blows onto the first baffle plate 220 along the V-shaped plate 212, part of the airflow passes through the through holes of the first baffle plate 220, and the remaining part of the airflow blows towards the non-hole areas of the first baffle plate 220 along the inclined direction and flows along the first baffle plate 220. This part of the airflow interferes with the airflow passing through the through holes in its flow path, affecting the speed of the airflow passing through the first baffle plate 220 and prolonging the time of the airflow flowing through the outer shell 100. At the same time, this part of the airflow flows along the first baffle plate 220 to the inner wall of the outer shell 100, forming a swirling turbulence, further prolonging the time of the airflow flowing through the outer shell 100. The above describes the flow state of the airflow in the first baffle cavity 241.

[0034] like Figure 3As shown, the airflow passing through the first turbulence perforation plate 220 flows into the second turbulence cavity 243 after passing through the direct illumination cavity 242. It can be understood that the second turbulence perforation plate 230 is a flat plate with multiple through holes evenly arranged on it. The size of the multiple through holes can be the same or different. This embodiment of the present invention does not limit this. The airflow hits the second perforated plate 230. A portion of the airflow passes through the through-holes in the second perforated plate 230 and exits through the outlet 120. The remaining airflow blows through the non-perforated areas of the second perforated plate 230, thus forming turbulence in opposite directions or at an angle. Part of the airflow moves along the direction close to the inner wall of the outer casing 100, forming a swirling turbulence, while another part moves away from the inner wall of the outer casing 100. During this movement, it interferes with the airflow passing through the through-holes in its flow path, affecting the speed at which the airflow passes through the second perforated plate 230 and prolonging the time the airflow spends flowing through the outer casing 100. Simultaneously, this portion of airflow, guided by the two branch channels 240, flows in opposite directions, further creating turbulence after interacting with each other. Finally, it passes through the second perforated plate 230 and exits through the outlet 120. The above describes the flow state of the airflow in the second turbulence cavity 243.

[0035] To further extend the time the airflow passes through the outer casing 100, in one embodiment, the second turbulence perforated plate 230 is provided with multiple through holes. The size of the through holes on the second turbulence perforated plate 230 gradually decreases from its middle position to both sides. The airflow flowing from the direct illumination cavity 242 into the second turbulence cavity 243 flows from both sides of the second turbulence perforated plate 230 towards the middle. Therefore, by setting the size of the through holes on the second turbulence perforated plate 230 to gradually decrease from its middle position to both sides, the airflow of the second turbulence perforated plate 230 gradually increases from both sides towards the middle, thereby allowing more airflow to flow from both sides of the second turbulence perforated plate 230 to its middle position, thus extending the time the airflow passes through the outer casing 100.

[0036] In order to ensure that the two airflows introduced into the second baffle plate 230 by the two diversion channels 240 are evenly distributed on the second baffle plate 230, in one embodiment, the second baffle plate 230 is set perpendicular to the direction from the air inlet 110 to the air outlet 120.

[0037] Of course, in other embodiments, the second flow-dispersing perforated plate 230 may also be inclined, which does not affect the implementation of the embodiments of the present invention.

[0038] The sterilization component 300 in this embodiment emits ultraviolet light. This ultraviolet light can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing cell death during growth and / or regeneration, thus achieving sterilization and disinfection. Simultaneously, pollutants undergo a chemical reaction under the synergistic effect of the ultraviolet light beam and the generated ozone, being photolyzed and oxidized, completely degrading into low-molecular-weight compounds, carbon dioxide, and water, removing irritating odors from the flue gas. To improve the sterilization effect, the sterilization component 300 is built into the outer casing 100, and the ultraviolet light emitted by the sterilization component 300 covers two diversion channels 240.

[0039] like Figure 4 As shown, in order to improve the sterilization effect, in one embodiment, a reflective layer is provided on the outer wall of the diversion box 210 near the diversion channel 240 so that the ultraviolet light in the diversion channel 240 is reflected and spreads throughout the entire diversion channel 240, so that the ultraviolet light illumination is uniform and there are no dead angles.

[0040] Understandably, the reflective layer can be a structure with reflective capabilities, such as a mirror or a reflective coating.

[0041] At the same time, the ultraviolet light facing the V-shaped surface 211 is reflected to pass through the air inlet 110, and pre-sterilizes and deodorizes the air that does not enter the air inlet 110.

[0042] In one embodiment, the sterilization component 300 includes multiple sterilization lamp groups, which are arranged sequentially on the inner walls of both sides of the housing 100 in a direction from the air inlet 110 to the air outlet 120. Each sterilization lamp group includes a circuit board and multiple sterilization lamps arranged sequentially in a vertical direction, with the lamps electrically connected to the circuit board.

[0043] Compared with the prior art: By fixing the diversion box 210 in the outer casing 100 and facing the air inlet 110, the straight flow direction of the airflow from the air inlet 110 to the air outlet 120 is changed to a bent flow direction along the two diversion channels 240 on both sides. Through the first turbulence perforated plate 220 set in the diversion channel 240, the airflow introduced by the air inlet 110 is blown obliquely towards the first turbulence perforated plate 220. A part of the airflow passes through the first turbulence perforated plate 220, and the rest of the airflow is blown along the oblique direction towards the non-perforated part of the first turbulence perforated plate 220, and flows against the first turbulence perforated plate 220 to the inner wall of the outer casing 100 to form turbulence, thereby prolonging the airflow path. During the time it takes for the airflow to pass through the outer casing 100, the airflow passing through the first baffle plate 220 is blown along the diversion channel 240 to the second baffle plate 230. A portion of the airflow passes through the second baffle plate 230 and is discharged from the air outlet 120, while the remaining portion of the airflow blows onto the non-perforated areas of the second baffle plate 230, thereby forming a turbulence with opposite or inclined directions. This further prolongs the time it takes for the airflow to pass through the outer casing 100. By prolonging the time it takes for the airflow to pass through the outer casing 100, the sterilization and deodorization effect of the sterilization component 300 on the airflow is improved. At the same time, the ultraviolet light emitted by the sterilization component 300 covers both diversion channels 240, and the ultraviolet light coverage area is large, which improves the sterilization and deodorization effect.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
