[0001] This application claims the benefit and priority of Indian Patent Application No. 202541021434, filed on March 10, 2025, the disclosure of which is incorporated herein by reference in its entirety. field

[0002] The present invention generally relates to the field of housings for accommodating engines and generators. background

[0003] Generator sets (“generator sets”, including, for example, diesel generator sets) are used to generate physical power in a variety of applications, such as mining applications. A generator set typically includes a diesel engine and a generator coupled to the engine. The engine is configured to mechanically drive the generator, which in turn generates electricity. The engine and generator may be housed within a casing that allows the generator set to operate outdoors and withstand extreme environments and factors such as temperature, humidity, and precipitation (e.g., rain, snow, ice, etc.). Overview

[0004] In some embodiments, a housing for a generator set includes a shell, a plurality of openings, and a plurality of louvers. The shell defines a partially enclosed space. The plurality of openings are formed on one side of the shell. The louvers are connected to the same side of the shell as the plurality of openings. Each louver includes a first leg and a second leg, the first leg having a vertical upper end and a vertical lower end, and the second leg having a vertical upper end and a lower end. The vertical upper end of the second leg is connected to the vertical upper end of the first leg. The lower end of the second leg is configured to guide air downwards.

[0005] In some embodiments, the multiple openings are defined by multiple louvers.

[0006] In some embodiments, the housing includes a base plate that defines an external portion of a space that is at least partially enclosed from the generator and engine.

[0007] In some embodiments, each venetian blind includes a plurality of legs, each leg including a vertical upper end.

[0008] In some embodiments, each louver extends upward at an angle relative to at least one side of the housing.

[0009] In some embodiments, each louver extends downward at an angle relative to at least one side of the housing.

[0010] In some embodiments, the plurality of blinds includes a first blind and a second blind below the first blind. A first leg of the first blind extends vertically downward beyond the first leg of the second blind, thereby restricting airflow into the space.

[0011] In some embodiments, the number of louvers included in the plurality of louvers corresponds to the target amount of airflow restriction by the plurality of louvers.

[0012] In some embodiments, the distance between each of the plurality of louvers corresponds to the target amount of airflow restriction imposed by the plurality of louvers.

[0013] In some embodiments, each of the plurality of blinds is vertically aligned with the other blinds in the plurality of blinds.

[0014] In some embodiments, each louver is partially flush with the housing.

[0015] In some embodiments, each louver is configured to guide dust downward toward the base plate of the housing.

[0016] In some embodiments, an airflow system for a generator set includes a housing, at least one opening, and a louver assembly coupled to the at least one opening. The louver assembly forms multiple airflow paths to deflect airflow into the housing.

[0017] In some embodiments, the venetian blind assembly includes a first venetian blind and a second venetian blind positioned below the first venetian blind. Each of the first and second venetian blinds directs airflow toward the other of the first and second venetian blinds.

[0018] In some embodiments, the louver assembly creates multiple airflow paths, causing dust in the air to deposit on the surface of the louver assembly facing the exterior of the housing.

[0019] In some embodiments, each venetian blind includes a first leg and a second leg. The first leg is longer than the second leg and is positioned to extend outward from the second leg relative to the space.

[0020] In some embodiments, a diesel generator set includes an engine, a generator, a housing, and a plurality of louvers. The engine provides mechanical power. The generator uses the mechanical power from the engine to provide electricity. The housing defines a space and ventilation openings, the space being at least partially enclosed by the housing and including an outer portion adjacent to the housing and an inner portion extending inward from the outer portion, the engine and the generator being located in the inner portion. The plurality of louvers are positioned at the ventilation openings and extend into the enclosed space. Each louver is configured to redirect airflow from the outside of the enclosed space toward the inner portion of the space in a first direction to the surface of one or more louvers and / or the outer portion of the space, thereby causing dust to deposit on each louver.

[0021] In some embodiments, each venetian blind includes a first leg and a second leg, and the upper end of the first leg is attached to the upper end of the second leg.

[0022] In some embodiments, the surface faces outward from the housing to collect dust redirected by multiple louvers.

[0023] In some embodiments, multiple louvers direct air downward toward the base plate of the housing.

In the drawings, like reference numerals generally identify like parts unless the context otherwise indicates. The illustrative embodiments described in the detailed description, drawings, and claims are not intended to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein.

Detailed description

[0032] The embodiments described herein generally relate to methods and apparatus for minimizing dust entry into an enclosure (e.g., a diesel generator set enclosure) due to ventilation air intake. In particular, the embodiments described herein generally relate to a louver assembly comprising a plurality of louvers disposed near ventilation air intakes of the enclosure. Enclosures typically include openings to facilitate the exchange of ventilation air between the interior of the enclosure and the surrounding environment, which cools internal components during operation. However, openings also provide pathways for dust and other solid matter particles in the environment to enter the enclosure. For this purpose, enclosures typically include deflectors (e.g., louvers, baffles, etc.) in the intake path to prevent dust from entering the enclosure. Deflectors typically increase the restriction along the flow path entering the enclosure. The louvers and / or louver assemblies according to this disclosure can redirect (e.g., deflect, reflect, etc.) air multiple times toward surfaces configured to collect and guide dust as it enters the enclosure. Each louver defines a flow path that can be adjusted to optimize air movement restriction within the enclosure.

[0033] In some embodiments, the position of the louvers can be adjusted. This allows for more effective air movement restriction, which causes airborne particles to settle (e.g., fall from the air). Furthermore, the louvers help provide a surface for collecting settled particles. Advantageously, dust is collected through the louvers, preventing particles from entering the housing. The various concepts described above and discussed in more detail below can be implemented in any of many ways, as the described concepts are not limited to any particular implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

[0034] Figure 1 This is a perspective view of a diesel generator set 100 according to an exemplary embodiment. Figure 2This is a side view through the sidewall of the diesel generator set 100. The diesel generator set 100 includes an engine 200, a generator 210, a housing 110, and two airflow assemblies. In some embodiments, a different number of airflow assemblies may be provided. According to an exemplary embodiment, the engine 200 is a diesel engine configured to burn diesel fuel to generate mechanical power. In some other embodiments, the engine 200 may be a gasoline engine, a natural gas engine, a dual-fuel engine, a biodiesel engine, an E85 engine, a flexible fuel engine, a gas turbine, or other types of internal combustion engine or drive. In various embodiments, the engine 200 may be a high-horsepower (HHP) engine capable of providing power in the range of 500 hp to 4500 hp or greater. The generator 210 may be an electric generator, an alternator, etc. In one embodiment, the engine 200 is coupled to the generator 210, for example, via a drive shaft (not shown). In operation, the engine 200 drives the generator 210 to generate electricity (e.g., power). For example, the engine 200 is configured to provide mechanical power, and the generator 210 is configured to use the mechanical power from the engine to provide electricity. Embodiments of this disclosure are also applicable to various types of prime movers (mechanical, electrical, hydraulic and / or fuel cell types) with various power intensities (low, medium and high horsepower).

[0035] like Figures 1-2As shown, housing 110 includes end walls (e.g., container walls, side walls, etc.) defining an internal volume (e.g., enclosed space, hollow area, etc.) for accommodating engine 200, generator 210, and other diesel generator set components. Housing 110 defines at least partially enclosed spaces and ventilation openings. The end walls include a housing bottom plate 112, a housing top plate 114, and housing side walls 116, which are arranged in a substantially perpendicular orientation relative to the housing bottom plate 112 and housing top plate 114. Housing bottom plate 112 and housing top plate 114 are connected to the edges of housing side walls 116 at their lateral edges. One or more doors may be provided in one or both of the housing side walls 116 to allow operators of the diesel generator set 100 (e.g., maintenance or repair personnel) to enter and access the internal volume defined by housing 110. A pair of outer shell end walls 118 are positioned at the longitudinal ends of the outer shell 110 and connected to the corresponding edges of the outer shell bottom plate 112, the outer shell top plate 114, and the outer shell side wall 116 to seal and isolate the outer shell 110 from the surrounding environment. The outer shell bottom plate 112, outer shell top plate 114, outer shell side wall 116, and outer shell end walls 118 can be formed of any suitable material (e.g., corrugated weathering steel). Furthermore, the outer shell 110 can have the dimensions of a standard ISO container (e.g., a length of approximately 6.1 meters, 12.2 meters, 14.6 meters, or approximately 16.2 meters and a height of approximately 2.59 meters, 2.9 meters, or approximately 3.2 meters). In some other embodiments, the outer shell 110 may include a non-ISO container, such as any non-standard sized ISO container. The outer shell 110 can be formed of a flat sheet metal or a non-metallic material (e.g., wood, plastic, reinforced polymer, cement, concrete, fiberglass, carbon fiber, etc.).

[0036] In some embodiments, the housing 110 may be disposed on the ground. In other embodiments, the housing 110 may be mounted on a fuel tank (not shown) disposed on the ground, or on a carriage (not shown) disposed on the ground. In other embodiments, the housing 110 may be positioned on a roof above the ground or at another suitable location.

[0037] The housing 110 is configured to provide airflow therethrough to cool the diesel generator set 100 and to provide air intake for the engine 200. For example... Figures 1 to 2 As shown, the housing 110 includes a ventilation air opening, which includes a ventilation air inlet and a ventilation air outlet. The ventilation air inlet includes a louver assembly 120 such that the louver assembly 120 is arranged at the ventilation opening. The ventilation air outlet is shown as an outlet assembly 130. In at least one embodiment, each of the louver assembly 120 and the outlet assembly 130 is defined in either of the housing end walls 118 and fluidly connects the internal volume of the housing 110 to the environment surrounding the housing 110. Figures 1-2 In the illustrated embodiment, the louver assembly 120 and the outlet assembly 130 are arranged on opposite ends of the housing 110, with the louver assembly 120 positioned on the housing end wall 118 closest to the generator 210 and the outlet assembly 130 positioned on the housing end wall 118 closest to the engine 200. In other embodiments, the louver assembly 120 and the outlet assembly 130 may be located at another location along the housing 110 (e.g., the housing top plate 114 and / or housing side wall 116). In some embodiments, the louver assembly 120 and the outlet assembly 130 may include louvers or other elements that allow air to enter the housing 110 while redirecting water (e.g., due to rainfall) and / or dust or other particles from the housing 110 or directing them to predefined discharge or collection areas of the housing 110. These predetermined discharge and / or collection areas are located in positions determined not to affect the operation of the diesel generator set 100. Dust entering the housing 110 can lead to system malfunctions of the diesel generator set 100 and dust accumulation on components housed within the housing 110. For example, if dust accumulates at the air intake of engine 200, engine 200 may draw in air less efficiently, thus limiting the operation of engine 200 and generator 210. Water entering housing 110 can negatively affect the performance of diesel generator set 100. For example, with significant exposure to water, the operation of generator 210 and / or engine 200 may be limited and / or malfunction (i.e., functional degradation). In some embodiments, housing 110 includes a collection and / or discharge area disposed in housing base plate 112. In some embodiments, the collection and / or discharge area is positioned near a corner of the internal volume of housing 110 (e.g., a junction between one of housing sidewalls 116, one of housing endwalls 118, and housing base plate 112), wherein the corner is recessed so that collected water and dust contained in the water exit housing 110.

[0038] In various embodiments, the inner surfaces of the housing bottom plate 112, housing top plate 114, housing sidewalls 116, and housing endwalls 118 may be lined with an acoustic damping material (e.g., an acoustic lining), which is configured to absorb and attenuate noise generated by the diesel generator set 100. Noise may be generated by internal components such as the engine 200, generator 210, etc. Alternatively or in combination, noise may be generated by airflow through the housing 110 via the louver assembly 120 and the outlet assembly 130.

[0039] The louver assembly 120 is a ventilation opening located at one of the end walls 118 of the housing. For example... Figures 1-2As shown, the louver assembly 120 is mechanically connected to one of the end walls 118 of the housing. In this way, a plurality of openings are formed on at least one side of the housing. In some embodiments, the plurality of louvers of the louver assembly 120 define a plurality of openings on at least one side of the housing. Figures 1-2 In some embodiments, the louver assembly 120 is an air inlet assembly configured to reflect air near the louver assembly 120 into the housing 110. In some embodiments, the louver assembly 120 is configured to deflect air as it moves into the housing 110. An outlet assembly 130 is mechanically coupled to a housing end wall 118 disposed on the end of the housing 110 opposite to the louver assembly 120. The outlet assembly 130 is an air outlet assembly configured to reflect air near the outlet assembly 130 out of the housing 110. Figures 1-2 As shown, each of the louver assembly 120 and the outlet assembly 130 is coupled to a corresponding housing end wall 118 to be substantially flush with the housing end wall 118. Figures 1-2 In some embodiments, each of the veil assembly 120 and the outlet assembly 130 is coupled to the housing 110 at all edges of the veil assembly 120 and the outlet assembly 130. In some embodiments, the veil assembly 120 and the outlet assembly 130 may be coupled to the housing 110 via fasteners, such that the outlet assembly 130 and the veil assembly 120 may be selectively removed from the housing 110. In other embodiments, the veil assembly 120 and the outlet assembly 130 may be hingedly coupled to the housing 110, such that the veil assembly 120 and the outlet assembly 130 may rotate about the connection point.

[0040] The venetian blind assembly 120 may be made of metals such as aluminum, carbon steel, plastic, and / or another rigid material or a combination of materials. In some embodiments, the venetian blind assembly 120 may be made of the same material as the housing 110, as referenced above. Figures 1-2 In some embodiments, the venetian blind assembly 120 may be made of an air-reflective material.

[0041] The outlet component 130 may be made of a metal such as aluminum, carbon steel, plastic, and / or another rigid material or a combination of materials. In some embodiments, the outlet component 130 may be made of the same material as the housing 110, as referenced above. Figures 1-2 As stated above.

[0042] In some embodiments, the outlet assembly 130 and the veil assembly 120 may be made of the same material, such that air exhibits substantially similar behavior at each of the veil assembly 120 and the outlet assembly 130. In other embodiments, the veil assembly 120 and the outlet assembly 130 may be made of different materials. For example, the veil assembly 120 may be made of a textured material to collect dust from the air entering the housing 110, while the outlet assembly 130 may be made of a smooth material to reduce friction experienced by the air leaving the housing 110.

[0043] In some embodiments, the diesel generator set 100 may include an airflow system. For example... Figures 1-2 As shown, the airflow system may include a housing 110, at least one opening on at least one side of the housing, and a louver assembly 120, wherein the louver assembly 120 is coupled to at least one opening and configured to guide air into the housing 110.

[0044] Figure 3 This is a side sectional view of a venetian blind assembly 120 according to an embodiment. The venetian blind assembly 120 includes a top, shown as a top 122 of the venetian blind assembly. The top 122 of the venetian blind assembly includes a first leg 124 and a second leg 126. Figures 3-5 As shown, the first leg 124 is disposed near the exterior of the housing 110, allowing it to interact with the environment surrounding the housing 110. In some embodiments, the top 122 of the venetian blind assembly is configured such that the vertical portions of the first leg 124 and the second leg 126 extend downward substantially parallel to the housing end wall 118. Figure 3 As shown, a portion of the first leg 124 extends into the housing 110 at a substantially upward angle relative to the housing base plate 112. In some embodiments, the vertical portion of the first leg 124 is configured such that it is substantially flush with the housing end wall 118 in which it is situated. In this configuration, the top 122 of the louver assembly is positioned such that there is no large gap between the louver assembly 120 and the housing end wall 118. In this way, air entering the housing 110 must come into contact with the louver assembly 120 to enter the housing 110.

[0045] The venetian blind assembly 120 includes one or more venetian blinds 300. As shown, each venetian blind 300 extends into an enclosed space defined by the housing 110. In some embodiments, each venetian blind 300 is configured to minimize dust ingress into the housing. In some embodiments, each venetian blind 300 of the venetian blind assembly 120 is arranged to cooperate with at least one other venetian blind 300 of the venetian blind assembly 120 to restrict airflow and minimize dust ingress into the housing 110. According to an exemplary embodiment, each venetian blind 300 is configured to collect dust entering the housing 110. In some embodiments, each venetian blind 300 of the venetian blind assembly 120 is coupled to the frame 128 such that each venetian blind 300 of the venetian blind assembly 120 is positioned in a substantially vertical linear configuration. In this way, each venetian blind 300 of the venetian blind assembly 120 is vertically aligned with all other venetian blinds 300 of the venetian blind assembly 120. In some embodiments, each louver 300 may be slidably coupled to the frame 128 such that each louver 300 can be vertically repositioned by the operator of the diesel generator set 100. In this configuration, the operator of the diesel generator set 100 can reposition any number of louvers 300 from the outside or inside of the housing 110. For example, when it is determined that the temperature inside the housing 110 is above a target range, the operator can vertically slide any number of louvers 300 in the louver assembly 120 away from other louvers 300 in the louver assembly 120 to increase the open surface area (i.e., the surface area in the louver assembly 120 not occupied by the louvers 300), thereby reducing the restriction of airflow into the housing 110 and increasing the amount of cooling air passing through the housing 110. In some embodiments, the louver assembly 120 is adjustable to include any number of louvers 300 to achieve at least one of a target airflow restriction value, a target temperature of the diesel generator set 100, or a target open surface area of ​​the louver assembly 120. In some embodiments, the distance between each louver 300 of the louver assembly 120 is adjustable to achieve at least one of a target airflow limit value, a target temperature of the diesel generator set 100, or a target open surface area of ​​the louver assembly 120.

[0046] In some embodiments, each louver 300 is rotatably coupled to either side of the frame 128 such that the louver 300 can rotate about the connection point between the louver 300 and the frame 128. For example, when it is determined that the engine 200 requires additional air intake, an operator can rotate any number of louvers 300 inward toward the housing 110 to increase the amount of open surface area, thereby reducing the restriction on air entering the housing 110 and increasing the air intake of the engine 200.

[0047] In some embodiments, each louver 300 is movably and rotatably coupled to the frame 128 such that each louver 300 can be moved and rotated by the operator of the diesel generator set 100. For example, when it is determined that the diesel generator set 100 needs more air to enter the housing 110, the operator can slide any number of louvers 300 of the louver assembly 120 vertically away from the other louvers 300 of the louver assembly 120, and subsequently rotate any number of louvers 300 inward toward the housing 110 to increase the amount of open surface area, thereby reducing the restriction on air entering the housing 110.

[0048] In some embodiments, each veneer 300 may be made of a metal such as aluminum, carbon steel, plastic, and / or another rigid material or a combination of materials. In some embodiments, each veneer 300 may be made of the same material as the veneer assembly 120. In some embodiments, each veneer 300 may be made of the same material as the housing 110, as referenced. Figures 1-2 As described above. In some embodiments, each louver 300 may be made of an air-reflective material.

[0049] like Figures 3-4 As shown, each louver 300 includes a first leg 310 and a second leg 320 coupled to the first leg 310. In some embodiments, each louver 300 is configured such that the first leg 310 is significantly longer than the second leg 320. In some embodiments, the first leg 310 and the second leg 320 are mechanically coupled (e.g., fused, welded, bonded with an adhesive product, etc.) such that the first leg 310 and the second leg 320 function as a single component. In some embodiments, the first leg 310 and the second leg 320 are detachably coupled (e.g., using magnetic coupling, using fastener coupling, etc.) such that the second leg 320 can be selectively removed from the first leg 310, thereby reducing airflow restriction into the housing 110 and facilitating airflow cooling of the intake of the diesel generator set 100 and the engine 200. In some embodiments, the louver 300 may be integrally formed such that the first leg 310 and the second leg 320 are a single component.

[0050] In some embodiments, each of the first leg 310 and the second leg 320 is made of the same material, such that the first leg 310 and the second leg 320 exhibit similar behavior, thereby allowing for predictable projection and uniform airflow. In some embodiments, the first leg 310 and the second leg 320 may be made of different materials to behave differently from each other.

[0051] like Figures 3-5As shown, the first leg 310 includes a lower end 312 and an upper end 314. In some embodiments, the lower end 312 and the upper end 314 are substantially vertical and parallel to each other, and parallel to the housing end wall 118. For example, the upper end 314 and the lower end 312 of the first leg extend vertically. Figures 3-4 As shown, the lower end 312 is positioned substantially flush with the vertical portion of the first leg 124, thereby substantially flush with the end wall 118 of the housing. In this way, the first leg 310 is at least partially flush with the wall of the housing 110. For example, the lower end 312 is the outermost portion of each louver 300 of the louver assembly 120 and is the first part of the louver 300 that comes into contact with the environment surrounding the housing. In this example, air entering the housing 110 from the environment surrounding the housing via the louver assembly 120 will first contact the lower end 312 upon entering the housing 110. In some embodiments, a portion of the first leg 310 extends into the housing 110 at a substantially upward angle relative to the housing base plate 112 between the lower end 312 and the upper end 314. For example, the first leg 310 extends at least partially at an upward angle to at least one side of the housing 110. This angled portion of the first leg 310 provides a site for accumulating and collecting dust and other particles contained in the air entering the housing 110. In this way, each veneer 300 is configured to collect dust entering the housing 110. In some embodiments, the veneer assembly 120 is configured such that the angled portions of each first leg 310 are accessible from the outside of the housing 110, thereby allowing the operator to easily clean (e.g., remove dust, etc.) the veneers 300.

[0052] Still referencing Figures 3 to 5The first leg 310 has a top surface. In some embodiments, the top surface of the first leg 310 is configured to collect dust and redirect air. When air is redirected and its movement is restricted, dust in the air settles. At the lower end 312, the top surface of the first leg 310 redirects air entering the housing 110 outwards, away from the housing 110. At the angled portion between the lower end 312 and the upper end 314, the top surface of the first leg 310 redirects air entering the housing 110 upwards, away from the first leg 310. At the upper end 314, the top surface of the first leg 310 redirects air upwards, away from the first leg 310. In some embodiments, the upper end 314 reflects air outwards, away from the housing 110. For example, when air enters the housing 110 and contacts the top surface of the first leg 310, the air can be redirected upwards and outwards from the housing 110, thereby substantially restricting the movement of the incoming air. When air movement is restricted, dust particles contained in the air can fall out of the air and settle on the top surface of the first leg 310. In some embodiments, the top surface of the first leg 310 is accessible from the outside of the housing 110, allowing the operator of the diesel generator set 100 to remove dust collected on the top surface of the first leg 310 from the outside of the housing 110. The first leg 310 has a bottom surface. In some embodiments, the bottom surface of the first leg 310 is configured to redirect dust and air entering the housing 110. At the lower end 312, the bottom surface of the first leg 310 redirects air from the first leg 310 into the housing 110. At the angled portion between the lower end 312 and the upper end 314, the bottom surface of the first leg 310 redirects air entering the housing 110 downwards and into the housing 110. In this way, each louver 300 is configured to direct air downwards. In some embodiments, at the upper end 314, the bottom surface of the first leg 310 is connected to the upper end 324 of the second leg 320.

[0053] Still referencing Figures 3-5 The second leg 320 includes a lower end 322 and an upper end 324. In some embodiments, the upper end 324 is substantially vertical and parallel to the lower end 312, the upper end 314, and the housing end wall 118. For example, the upper end 324 extends vertically. Figures 3-5 As shown, the upper end 314 of the first leg 310 is connected to the upper end 324 of the second leg 320. In some embodiments, the upper end 324 is mechanically connected to the upper end 314. In some embodiments, the upper end 324 is detachably connected to the upper end 314.

[0054] In some embodiments, a portion of the second leg 320 extends into the housing 110 at a substantially downward angle relative to the housing top 114 between the upper end 324 and the lower end 322. For example, the second leg 320 extends at least partially to at least one side of the housing 110 at a downward angle. Figure 3 As shown, the lower end 322 extends into the housing at a greater downward angle than the angled portion between the upper end 324 and the lower end 322. In this way, dust entering the housing 110 and contacting the lower end 322 is redirected toward the housing base plate 112 to avoid substantially affecting the operation of the diesel generator set 100. For example, the lower end 322 of the second leg 320 is configured to guide air downwards.

[0055] like Figures 3-5 As shown, the second leg 320 has a bottom surface. In some embodiments, the bottom surface of the second leg 320 is configured to redirect air and dust entering the housing 110. At the upper end 324, the bottom surface of the second leg 320 is connected to the upper end 314 of the first leg 310. At the angle between the lower end 322 and the upper end 324, the bottom surface of the second leg 320 redirects air downwards and away from the second leg 320. At the lower end 322, the bottom surface of the second leg 320 reflects air downwards and into the housing 110. The second leg 320 has a top surface. In some embodiments, the top surface of the second leg 320 is configured to redirect dust falling into the housing 110 toward a predetermined collection area in the housing bottom plate 112. In some embodiments, the second leg 320 acts as a barrier between dust falling into the housing 110 and air entering the housing 110. In this way, falling dust is not further carried into the housing 110 by the incoming air.

[0056] like Figure 3 As shown, the venetian blind assembly 120 includes a plurality of venetian blinds. In the illustrated configuration, there is a first venetian blind 300 positioned near the top 122 of the venetian blind assembly, and a second venetian blind 300 positioned below the first venetian blind 300. In the illustrated embodiment, the lower end 312 of the first venetian blind 300 extends vertically beyond the upper end 314 of the second venetian blind 300, thereby preventing incoming air from having a direct (i.e., unrestricted, etc.) path into the housing 110. The vertical orientation of the upper end 314 of the second venetian blind 300 prevents water or other liquids used for cleaning the venetian blind assembly 120 from entering the housing 110. In some embodiments, each of the first venetian blind 300 and the second venetian blind 300 is configured to guide air at least partially toward the other of the first venetian blind 300 and the second venetian blind 300. For example, the louver assembly 120 includes a first louver and a second louver located below the first louver, such that a first leg of the first louver extends vertically downward, at least partially beyond the first leg of the second louver, thereby restricting airflow.

[0057] Now for reference Figure 4 The diagram shows views of a first venetian blind 300 and a second venetian blind 300 according to an embodiment. (Refer to the above...) Figure 3Briefly disclosed, a flow path 400 is shown. The flow path 400 is formed by the louver assembly 120 and allows dust in the air entering the housing to be collected before entering the housing 110. (See attached image.) Figure 4 As shown, flow path 400 is an indication of the path of air and thus airborne particles (e.g., dust, etc.) into housing 110. The dashed lines of flow path 400 indicate the flow path. Figure 4 Further including multiple dust particles 410. The louver assembly 120 is configured such that air entering the housing 110 is reflected (e.g., redirected, etc.) upon contact with the louvers 300 of the louver assembly 120. In this way, the louver assembly 120 causes multiple redirections of air entering the housing 110, thereby restricting air movement. Restriction of air movement causes airborne particles to settle (e.g., fall from the air, etc.), thereby preventing a large number of particles (e.g., dust) from entering the housing 110. For example, the louver assembly 120 is coupled to the housing 110 and configured such that it forms a flow path 400 for guiding air into the housing, wherein the louver assembly 120 is configured to deflect air as it moves into the housing 110.

[0058] When air first enters the housing 110, it travels around the lower end 312 of each of the first and second louvers 300 to the first position 401. Once it approaches the first position 401, the air can travel toward the interior of the housing, and then inside the housing, the air can reach the second position 402.

[0059] At the second position 402, air and dust particles 410 can come into contact with the top surface of the first leg 310 of the second louver 300. In some embodiments, dust particles 410 will begin to accumulate on the first leg 310 at the second position 402. In some embodiments, dust particles 410 will continue to travel into the housing 110 and be redirected toward the bottom surface of the first louver 300. In some embodiments, dust particles 410 and air will travel toward the third position 403.

[0060] like Figure 4 As shown, the third position 403 is defined by the upper end 314 of the second louver 300. At the third position 403, a number of dust particles 410 accumulate while air continues to be redirected. In some embodiments, the upper end 314 of the second louver 300 redirects air and dust particles 410 upwards and away from the second louver 300 toward the first louver 300, as shown in the flow path 400. In some embodiments, the air and dust particles 410 will travel toward the fourth position 404.

[0061] The fourth position 404 is defined by the connection point between the first leg 310 and the second leg 320 of the first louver 300. In some embodiments, the angle formed by the connection of the first leg 310 and the second leg 320 of the louver 300 defines the redirection caused at the fourth position 404. At the fourth position 404, air and a plurality of dust particles 410 are redirected downward and enter the housing 110, as shown in the flow path 400. After reaching the fourth position 404, the air and dust particles 410 travel downward and enter the housing 110. In some embodiments, the air and dust particles 410 will travel toward the fifth position 405.

[0062] like Figure 4 As shown, the fifth position 405 is partially defined by the second leg 320 of the second louver 300. As shown in the first position 401, air and dust particles 410 at the fifth position 405 are guided downwards by the second leg 320 of the second louver 300 and into the housing 110. The redirection of the second leg 320 of the second louver 300 directs air into the housing 110 and directs dust particles 410 downwards and toward a predetermined collection area inside the housing 110. Figure 4 As shown, the first louver 300 and the second louver 300 are configured to direct air at least partially toward another of the first louver 300 and the second louver 300.

[0063] Now for reference Figure 5 The image shows a perspective view of a portion of a venetian blind assembly 120 according to an embodiment. The venetian blind assembly 120 may include a frame 128. In some embodiments, the frame 128 includes a top 122 of the venetian blind assembly. In some embodiments, the top 122 of the venetian blind assembly is configured to connect the venetian blind assembly 120 to a housing 110. Figure 5 As shown, the venetian blind assembly 120 may include one or more fasteners 500 configured to engage the venetian blind assembly 120 with the housing 110. In some embodiments, the venetian blind assembly 120 and the housing end wall 118 may include a plurality of holes to receive one or more fasteners 500. Figure 5 As shown, the top surface of the first leg 310 of each louver 300 can collect dust particles 410 that enter the housing 110.
