Description

Technical Field

[0001] The present invention relates to electric power equipment, and more particularly to electric power equipment having a structure capable of first removing dust mixed in a fluid used for cooling and then efficiently discharging the dust to the outside. Background Art

[0002] Power equipment refers to devices that can connect to external power sources and loads, converting and transmitting electricity. Power equipment can receive electricity from an external power source, step up or down the voltage, and then transmit it to the external load.

[0003] To perform the functions described above, various electrical devices are installed within power equipment. As these devices operate, heat is generated within the equipment. If this heat is retained within the equipment, it could damage the electrical devices.

[0004] Therefore, general power equipment includes components for cooling installed electrical devices. As an example, power equipment can cool installed electrical devices using external air or the like in a form of air cooling.

[0005] However, the outside air may contain various foreign matter such as dust and powder. If the outside air flows into the interior of the power equipment without a separate filtering process, there is a possibility that the installed electrical devices will be damaged by the foreign matter mixed in the outside air for air cooling.

[0006] To prevent this phenomenon, a filter is installed at a portion of the electric power equipment that communicates with the outside. The filter is configured to filter the incoming outside air, thereby filtering out foreign matter mixed in the outside air.

[0007] As power equipment is used, a large amount of foreign matter accumulates in the filters. This makes it difficult for outside air to flow smoothly, and the reliability of the filtration process may be reduced. Furthermore, the filter replacement cycle is shortened, which may increase the time and cost required to operate the power equipment.

[0008] On the other hand, even if foreign matter mixed with the incoming fluid is removed, a method for discharging the foreign matter back to the outside is required. In other words, if the removed foreign matter remains inside the power equipment, it not only hinders the flow of the incoming fluid but also poses a risk of damaging the power equipment due to the retained foreign matter.

[0009] Korean Patent No. 10-1476003 discloses a housing including a module having a thermosyphon cooler arrangement. Specifically, the housing includes a module having a thermosyphon cooler arrangement capable of guiding the flow of incoming cooling air using an additional first opening for receiving the cooling air flow.

[0010] However, the box disclosed in the prior art only provides a solution for guiding the flow of cooling air, but does not provide a solution for filtering foreign matter mixed in the air.

[0011] Korean Patent No. 10-0896777 discloses a multi-power supply device with improved installability, and more specifically, discloses a multi-power supply device having an additional cooling fan and capable of flowing cooling air for cooling the power devices.

[0012] However, the multi-power supply device proposed in the above-mentioned prior art document only proposes a solution for allowing the cooling air to flow into the interior, and does not propose a solution for filtering foreign matter mixed in the cooling air.

[0013] Furthermore, the above-mentioned prior art does not provide a solution for preventing the filtered foreign matter from being retained in the device when the foreign matter is filtered.

[0015] Korean Patent No. 10-0896777 (May 11, 2009) Summary of the Invention

[0042] Effects of the Invention

[0043] According to the above configuration, the electric power equipment according to the embodiment of the present invention can effectively remove foreign matter mixed in the fluid flowing in for cooling.

[0044] The power equipment is equipped with a purification module. The purification module includes multiple vortex-forming components that shape the flow of fluid entering from the outside into a vortex. As the fluid flows through the purification module, foreign matter and other particles in the fluid are radially moved outward by centrifugal force and centrifugally separated.

[0045] A foreign matter discharge portion is formed through the periphery of the purification module. Centrifugally separated foreign matter and the like are discharged into a space within the frame portion through the foreign matter discharge portion. The fluid from which the foreign matter and the like are separated can flow into the interior of the power equipment through the filter element.

[0046] Therefore, foreign matter mixed in the external fluid can be effectively removed.

[0047] Furthermore, according to the above configuration, the power equipment according to the embodiment of the present invention can adjust the number of components for removing foreign matter according to the capacity.

[0048] The purification module provided in the purification part can be detachably coupled to the purification cover. The number of the purification modules can be adjusted according to the capacity of the power equipment, that is, the heat generated by the devices provided inside the power equipment.

[0049] In one embodiment, the number of purification modules and the number of coupling openings formed in the purification cover can be changed according to the capacity of the power equipment. Alternatively, a sufficient number of coupling openings can be formed in the purification cover, and purification modules can be coupled to only a portion of the plurality of coupling openings.

[0050] Therefore, the number of purification modules can be adjusted according to the capacity of the power equipment, thereby increasing the degree of design freedom and enabling proactive response based on the capacity of the power equipment.

[0051] Furthermore, according to the above configuration, the electric power equipment according to the embodiment of the present invention can easily handle foreign matter separated from the fluid.

[0052] The purification module is partially housed within the purification main body. The hollow space within the module communicates with the interior of the purification main body, i.e., the purification main body space, through a dust discharger. The dust discharger extends through the underside of the purification main body, radially surrounding the hollow space within the module. This allows centrifugally separated foreign matter to flow easily into the purification main body space.

[0053] The main purification space is enclosed by a purification cover. A cover communication hole is formed through the first purification cover, which surrounds the main purification space from one side. The cover communication hole connects the cover space with the main purification space. A flow path, which forms a flow path for discharging foreign matter, is coupled to the cover communication hole and communicates with the main purification space.

[0054] A discharge section is provided below the purification unit. The purification unit and discharge section are connected and joined by a flow path. The discharge section includes an exhaust fan assembly, which applies suction to foreign matter trapped in the main purification unit space, which is connected to the flow path. When the exhaust fan assembly is activated, foreign matter trapped in the main purification unit space flows out through the flow path into the discharge section.

[0055] Therefore, the foreign matter separated from the fluid can move to the discharge unit without being retained in the purification unit. As a result, the foreign matter separated from the fluid can be easily processed.

[0056] Furthermore, according to the above configuration, the electric power device according to the embodiment of the present invention can easily discharge foreign matter separated from the fluid.

[0057] The exhaust part includes the exhaust fan assembly and an exhaust frame for supporting the exhaust fan assembly. The exhaust frame includes a support frame for supporting the exhaust fan assembly. The exhaust fan assembly is placed on the exhaust frame and supported by the support frame.

[0058] A support space is formed inside the support frame. In addition, a support communication portion is formed through a surface of the support frame that surrounds the support space in a radial direction. The support communication portion is configured to connect the support space with the outside.

[0059] A portion of the exhaust frame (ie, the third exhaust frame) is coupled to the exhaust fan assembly. A discharge opening is formed through the interior of the exhaust frame, thereby connecting the exhaust fan assembly and the support space.

[0060] Therefore, foreign matter and the like moved to the discharge portion by the conveying force applied by the discharge fan assembly can be discharged to the outside of the electric equipment after sequentially passing through the discharge fan assembly, the support space, and the support connecting portion.

[0061] Furthermore, according to the above configuration, the electric power equipment according to the embodiment of the present invention can be prevented from being damaged by foreign matter separated from the fluid.

[0062] As described above, the external fluid can flow into the interior of the electric device after the foreign matter etc. is removed. Therefore, the components of the electric device will not be damaged due to cooling of the inflowing fluid.

[0063] Furthermore, foreign matter separated from the fluid can be discharged to the outside of the power equipment through the discharge unit without remaining in the purification unit. Therefore, problems caused by the remaining foreign matter, such as a decrease in the separation efficiency of the foreign matter, can be prevented.

[0064] This can prevent damage to electric equipment caused by foreign matter separated from the fluid.

[0065] The effects of the present invention are not limited to the above-described effects, but should be understood to include all effects that can be derived from the configurations of the invention described in the detailed description of the present invention or the claims.

The electric power device 1 may be any device capable of connecting to an external power source or load and performing a predetermined function. In one embodiment, the electric power device 1 may be an ESS (Energy Storage System).

[0098] Various components (not shown) may be installed inside the electric power equipment 1. These components (not shown) may be configured to be energized by an external power source or load and to perform various functions.

[0099] The power device 1 may be in any form that can perform a predetermined function. In the illustrated embodiment, the power device 1 is in the shape of a polygonal column having a length in the left-right direction longer than in the front-back direction and having a height in the top-bottom direction.

[0100] The power device 1 according to the present embodiment can utilize an external fluid to cool the heat generated during the operation of the components (not shown). In this case, the external fluid can be flowed into the power device 1 after removing any foreign matter mixed in it. This prevents damage to the components (not shown) or malfunction of the power device 1 caused by foreign matter.

[0101] Furthermore, the power device 1 according to the embodiment of the present invention can discharge separated foreign matter, etc. to the outside. Therefore, the separated foreign matter, etc., does not remain inside the power device 1, and thus does not transfer to the components (not shown) of the power device 1 or hinder the operation of other components (not shown).

[0102] In the illustrated embodiment, the electric power device 1 includes a housing portion 10 , a purification portion 20 , a discharge portion 30 , and a flow path portion 40 .

[0103] The housing 10 forms the outer shape of the power device 1. The housing 10 has a space therein for accommodating other components of the power device 1. In the illustrated embodiment, the housing 10 includes a purification unit 20, a discharge unit 30, and a flow path 40.

[0104] The space of the housing 10 is electrically connected to the outside. The structure (not shown) housed in the space of the housing 10, that is, the electrically operated structure (not shown), can be electrically connected to an external power source or load.

[0105] The cover 10 may have any shape that can accommodate the configuration of the electric power device 1. In the illustrated embodiment, the cover 10 has a polygonal column shape, similar to the outer shape of the electric power device 1.

[0106] In the illustrated embodiment, the cover portion 10 includes a first outer surface 11 , a second outer surface 12 , a window 13 , and a cover space 14 .

[0107] The first outer surface 11 forms one side, ie, the front side, of the cover body 10 in the illustrated embodiment. The first outer surface 11 surrounds the cover body space 14 from the one side, ie, the front side in the illustrated embodiment.

[0108] The first outer surface 11 may be formed in accordance with the shape of the cover body 10. In the illustrated embodiment, the first outer surface 11 is a quadrilateral plate having a width in the left-right direction, a height in the up-down direction, and a thickness in the front-back direction.

[0109] The first outer surface 11 is continuous with the second outer surface 12 .

[0110] The second outer surface 12 forms the other side of the cover portion 10, ie, the width direction surface in the illustrated embodiment. A pair of second outer surfaces 12 surround the cover space 14 from the other side, ie, the left and right sides in the illustrated embodiment.

[0111] The second outer surface 12 may be formed in accordance with the shape of the cover body 10. In the illustrated embodiment, the second outer surface 12 is a quadrilateral plate having a width in the front-to-back direction, a height in the up-down direction, and a thickness in the left-to-right direction.

[0112] The second outer surface 12 is disposed adjacent to the first outer surface 11. In the illustrated embodiment, the front end portion of the second outer surface 12 is disposed adjacent to the left end portion and the right end portion of the first outer surface 11, respectively.

[0113] A window 13 is provided on the first outer surface 11 .

[0114] The window 13 forms a flow path for external fluid to flow into the housing space 14. At least a portion of the window 13 can be open, while another portion can be closed. The window 13 connects the outside with the housing space 14. In the illustrated embodiment, the window 13 can be provided in the form of a blind.

[0115] The windows 13 may be formed of a plurality of windows. In the illustrated embodiment, the windows 13 are biased toward the upper side of the interior of the first outer surface 11 and are located on the left and right sides respectively.

[0116] A space partially surrounded by the first outer surface 11 and the second outer surface 12 may be defined as a cover space 14 .

[0117] The housing space 14 is a space formed inside the housing portion 10. The housing space 14 accommodates the components of the power device 1, namely, the purification unit 20, the discharge unit 30, and the flow path unit 40. Furthermore, the housing space 14 can be electrically connected to the components of the power device 1 described above (i.e., the components electrically connectable to an external power source or load).

[0118] A portion of the cover space 14 is partially surrounded by the first outer surface 11, and another portion is partially surrounded by the second outer surface 12. In the illustrated embodiment, the front side of the cover space 14 is surrounded by the first outer surface 11, and the left and right sides of the cover space 14 are respectively surrounded by the second outer surface 12.

[0122] Refer again Figures 1 to 4 The power equipment 1 according to the embodiment of the present invention includes a purification unit 20 .

[0123] The purifying unit 20 filters the external fluid flowing into the housing 10. The external fluid can be separated from foreign matter and the like while passing through the purifying unit 20, and then flow into the electric power device 1.

[0124] The purifying unit 20 may be any type capable of removing relatively large dust mixed in the external fluid. In the illustrated embodiment, the purifying unit 20 may be configured to separate the dust mixed in the external fluid by centrifugation separation.

[0125] The purification unit 20 is coupled to the housing 10. Specifically, the purification unit 20 is housed within the housing space 14 formed within the housing 10. In this case, the purification unit 20 can be positioned toward one side in the height direction of the housing space 14, i.e., toward the upper side in the illustrated embodiment. In other words, the purification unit 20 is positioned upward relative to the discharge unit 30.

[0126] Thus, the foreign matter separated in the purification unit 20 is not only dropped by the exhaust fan assembly 600 provided in the exhaust unit 30 described later, but also dropped by gravity.

[0127] The purification unit 20 is disposed adjacent to the discharge unit 30. Foreign matter and the like separated by the purification unit 20 can be discharged to the discharge unit 30. The purification unit 20 and the discharge unit 30 are in communication with each other.

[0128] The purification unit 20 is coupled to the flow path unit 40 . A space formed inside the purification unit 20 communicates with the flow path unit 40 , so that foreign matter separated in the purification unit 20 can flow out to the discharge unit 30 through the flow path unit 40 .

[0129] Below, refer to Figures 5 to 16 , the purification unit 20 is described in detail. In the illustrated embodiment, the purification unit 20 includes a purification frame 100, a purification cover 200, a purification body 300 and a purification module 400.

[0130] The purification frame 100 forms a main body of the purification unit 20. A space is formed inside the purification frame 100 to accommodate the purification main body 300 and the purification module 400.

[0131] The purification frame 100 is housed in the housing space 14 and is partially surrounded by the first outer surface 11 and the second outer surface 12. In the illustrated embodiment, the front side of the purification frame 100 is surrounded by the first outer surface 11, and the left and right sides of the purification frame 100 are respectively surrounded by the second outer surface 12.

[0132] The clean frame 100 is coupled to the clean cover 200. The clean cover 200 covers the space formed inside the clean frame 100 from one side and is coupled to the clean frame 100. In the illustrated embodiment, the clean cover 200 is coupled to the front side of the clean frame 100.

[0133] The purification frame 100 is combined with the purification body 300 and the purification module 400. As described later, the purification body 300 and the purification module 400 are respectively combined with the purification cover 200. Therefore, it can be understood that the purification frame 100 is combined with the purification body 300 and the purification module 400 through the purification cover 200.

[0134] The purification frame 100 is in communication with the outside. Specifically, the purification frame 100 is in communication with the outside through the cover space 14 . External fluid can flow into the internal space of the purification frame 100 through the cover space 14 .

[0135] In the illustrated embodiment, the purification frame 100 includes a receiving frame 110 , a first purification frame 120 , a second purification frame 130 , and a third purification frame 140 .

[0136] The receiving frame 110 forms a part of the outer shape of the purification frame 100. The receiving frame 110 forms the skeleton of the purification frame 100 and is respectively combined with other components of the purification frame 100, namely the first purification frame 120, the second purification frame 130 and the third purification frame 140 in the illustrated embodiment.

[0137] The receiving frame 110 may be formed in accordance with the shape of the housing space 14. In the illustrated embodiment, the receiving frame 110 is in the shape of a quadrangular prism having a height in the vertical direction, a width in the horizontal direction, and a length in the front-rear direction.

[0138] One side of the receiving frame 110 in the height direction, that is, the upper side in the illustrated embodiment, is coupled to the first purification frame 120. Each side of the receiving frame 110 in the width direction, that is, the left and right sides in the illustrated embodiment, is coupled to the second purification frame 130. The other side of the receiving frame 110 in the height direction, that is, the lower side in the illustrated embodiment, is coupled to the third purification frame 140.

[0139] In the illustrated embodiment, the receiving frame 110 includes a receiving space 111 and a communication opening 112 .

[0140] The accommodation space 111 is a space formed inside the accommodation frame 110. The accommodation space 111 accommodates the purification body 300 and the purification module 400 coupled to the purification cover 200. The accommodation space 111 communicates with the housing space 14 and the outside.

[0141] The accommodating space 111 is partially surrounded by the first to third cleansing frames 120, 130, and 140. In the illustrated embodiment, the upper side of the accommodating space 111 is surrounded by the first cleansing frame 120, the left and right sides of the accommodating space 111 are surrounded by the second cleansing frame 130, and the lower side of the accommodating space 111 is surrounded by the third cleansing frame 140.

[0142] The receiving space 111 may have a shape corresponding to the receiving frame 110. In the illustrated embodiment, the receiving space 111 is formed in a quadrangular prism shape having a width in the left-right direction, a height in the up-down direction, and a depth in the front-back direction.

[0143] The side of the accommodation space 111 , which faces the first outer surface 11 , ie, the front side in the illustrated embodiment, is open.

[0144] The other side of the accommodating space 111 opposite to the one side, ie, the rear side in the illustrated embodiment, communicates with the outside through the communication opening 112 .

[0145] The communication opening 112 accommodates the purification body 300. The communication opening 112 is formed through the other side of the surface of the receiving frame 110 opposite the first outer surface 11, that is, the rear side in the illustrated embodiment. The communication opening 112 connects the receiving space 111 with the outside on the other side, that is, the rear side.

[0146] The communication opening 112 may be any shape that can accommodate the purification body 300. In the illustrated embodiment, the communication opening 112 is formed as a quadrilateral plate-shaped opening having a width in the left-right direction, a height in the up-down direction, and a thickness in the front-back direction.

[0147] The communication openings 112 may be formed in a plurality. The plurality of communication openings 112 may be formed at different positions on the other side surface of the receiving frame 110. In the illustrated embodiment, the communication openings 112 include a first communication opening 112a, a second communication opening 112b, a third communication opening 112c, and a fourth communication opening 112d.

[0148] In the illustrated embodiment, the first communication opening 112a is biased toward the upper left, the second communication opening 112b is biased toward the upper right, the third communication opening 112c is biased toward the lower left, and the fourth communication opening 112d is biased toward the lower right.

[0149] The number and configuration of the communication openings 112 may vary depending on the number and configuration of the purification bodies 300. Specifically, in the illustrated embodiment, it is understood that the purification cover 200, the purification body 300, and the purification module 400 each have four, and therefore the communication openings 112 are also formed by four.

[0150] The first purification frame 120 forms another part of the outer shape of the purification frame 100. The first purification frame 120 is coupled to one side in the height direction of the receiving frame 110, that is, the upper side in the illustrated embodiment. The first purification frame 120 surrounds the receiving space 111 from the upper side.

[0151] The first purification frame 120 can be formed to correspond to the shape of the side surface of the receiving frame 110, that is, the upper side surface in the illustrated embodiment. In the illustrated embodiment, the first purification frame 120 is formed into a quadrilateral plate having a thickness in the vertical direction and a length extending in the left-right direction longer than in the front-back direction.

[0152] Each end portion of the first purification frame 120 in the extension direction, ie, the left end portion and the right end portion in the illustrated embodiment, is disposed adjacent to the second purification frame 130 .

[0153] The second cleanroom frame 130 forms another portion of the cleanroom frame 100's exterior. There are multiple second cleanroom frames 130, each attached to each widthwise side of the receiving frame 110 (i.e., the left and right sides in the illustrated embodiment). The second cleanroom frames 130 surround the receiving space 111 from these sides. A pair of second cleanroom frames 130 are arranged facing each other, sandwiching the receiving frame 110 between them.

[0154] The second purification frame 130 can be formed to correspond to the shapes of the side surfaces of the receiving frame 110, namely, the left and right sides in the illustrated embodiment. In the illustrated embodiment, the second purification frame 130 is formed into a quadrilateral plate having a length extending in the front-to-back direction that is shorter than its length extending in the vertical direction and having a thickness in the horizontal direction.

[0155] The second clean frame 130 is disposed adjacent to each widthwise end of the first clean frame 120 at its upper end in the height direction (i.e., the vertical end in the illustrated embodiment). The second clean frame 130 is disposed adjacent to each widthwise end of the third clean frame 140 at its lower end in the height direction (i.e., the vertical end in the illustrated embodiment).

[0156] The third purification frame 140 forms the rest of the outer shape of the purification frame 100. The third purification frame 140 is coupled to the other side of the receiving frame 110 in the height direction, that is, the lower side in the illustrated embodiment. The third purification frame 140 surrounds the receiving space 111 from the other side, that is, the lower side.

[0157] The third purification frame 140 supports the receiving frame 110 and the first and second purification frames 120 and 130 coupled thereto. The third purification frame 140 is positioned on the discharge frame 500 provided at the discharge unit 30. That is, the third purification frame 140 is located between the receiving frame 110 and the discharge frame 500.

[0158] The third purification frame 140 may be in any shape capable of supporting the receiving frame 110. In the illustrated embodiment, the third purification frame 140 has a fork shape with an opening formed on the rear side and continuous front, left, and right sides.

[0159] Reference Figures 7 to 10 The purification unit 20 of the illustrated embodiment includes a purification cover 200 .

[0160] The purification cover 200 forms a portion of the outer shape of the purification unit 20. The purification cover 200 may have a through hole formed therein, and the purification module 400 may be inserted through the through hole.

[0161] The purification cover 200 is combined with the purification body 300. The purification cover 200 forms a space therebetween and is combined with the purification body 300. The purification module 400 can be partially accommodated in the space. In addition, the fluid passing through the purification module 400 can flow in the space.

[0162] The purification cover 200 can be tightly coupled to the purification body 300. Specifically, the space between the purification cover 200 and the purification body 300 can be sealed by the purification cover 200 and the purification body 300, thereby cutting off any external communication. Therefore, external fluid must pass through the purification module 400 before it can flow into the space between the purification cover 200 and the purification body 300.

[0163] The purification cover 200 is combined with the purification module 400. The purification module 400 is integrated through the purification cover 200. A portion of the purification module 400 can be exposed to the outside of the purification cover 200, and the other portion can be accommodated in the space formed inside the purification body 300 combined with the purification cover 200.

[0164] The purification cover 200 is arranged to overlap with the purification body 300 and the purification module 400 in its thickness direction, that is, in the front-to-back direction in the illustrated embodiment.

[0165] There may be a plurality of purification covers 200. The plurality of purification covers 200 may be combined with a plurality of purification bodies 300 and purification modules 400, respectively. Figures 1 to 4 In the illustrated embodiment, there are four purification covers 200 , which are respectively combined with four purification bodies 300 and four groups of purification modules 400 .

[0166] In the illustrated embodiment, the purification cover portion 200 includes a first purification cover 210 coupled to the first purification body 310 and a second purification cover 220 coupled to the first purification body 310 and the second purification body 320 , respectively.

[0167] The first purification cover 210 forms the outermost side of the purification unit 20. In the illustrated embodiment, the first purification cover 210 forms the front end of the purification unit 20. In other words, the first purification cover 210 is located closest to the first outer surface 11 of the purification unit 20.

[0168] The first purification cover 210 is coupled to the first purification body 310. Specifically, the first purification cover 210 covers the first purification body space 312 formed within the first purification body 310 from the outside, i.e., the front side in the illustrated embodiment, and is coupled to the first purification body 310. As described above, in one embodiment, the first purification cover 210 and the first purification body 310 can be tightly coupled.

[0169] The first clean cover 210 is coupled to the second clean cover 220. In the illustrated embodiment, the first clean cover 210 and the second clean cover 220 are coupled to each other by a plurality of fastening members (not labeled) located inside the outer periphery of the first clean cover 210. The first clean cover 210 is disposed so as to face the second clean cover 220 across the first clean body 310.

[0170] The first purge cover 210 is coupled to the purification module 400. The first purge cover 210 is configured to support a portion of the purification module 400, specifically the front side in the illustrated embodiment. This is achieved by the purification module 400 being coupled through a first coupling opening 212 formed in the first purge cover 210. In the illustrated embodiment, the first purge cover 210 supports the module body 410 of the purification module 400.

[0171] The first purification cover 210 can be of any shape that is combined with the first purification body 310, seals the first purification body space 312, and partially supports the purification module 400. In the illustrated embodiment, the first purification cover 210 is a polygonal plate with a plurality of corners.

[0172] Specifically, in the illustrated embodiment, the first purge cover 210 includes a first portion located at the upper side and extending horizontally; and a pair of second portions extending downward from each end of the first portion and including a bent portion protruding outward. Furthermore, in the illustrated embodiment, the first purge cover 210 includes a third portion extending vertically downward from each end of the second portion, and a fourth portion extending between the ends of the third portion.

[0173] In the illustrated embodiment, the first purification cover 210 includes a first purification plate 211 , a first combining opening 212 , and a cover communication hole 213 .

[0174] The first purification plate 211 forms the main body of the first purification cover 210. The first purification plate 211 has a plate shape and is coupled to the first purification body 310. The first purification plate 211 is configured to cover the first purification body space 312 formed inside the first purification body 310.

[0175] The first purification plate 211 can be divided into a plurality of parts. In the illustrated embodiment, the first purification plate 211 includes a first part 211a located at a relatively upper side and covering the first space 312a of the first purification main body space 312, and a second part 211b located at a relatively lower side and covering the second space 312b of the first purification main body space 312.

[0176] At this time, the first portion 211a and the second portion 211b can be formed to correspond to the shapes of the first space 312a and the second space 312b. In the illustrated embodiment, the first portion 211a is formed to have an overall hexagonal cross-section with its upper corners extending longer than the hexagonal corners. Furthermore, the second portion 211b is formed to have a quadrilateral cross-section with a length extending in the left-right direction longer than in the vertical direction.

[0177] The shapes of the first portion 211 a and the second portion 211 b may be changed according to the shapes of the first space 312 a and the second space 312 b .

[0178] A plurality of through holes are formed inside the first purification plate 211. In the illustrated embodiment, a first coupling opening 212 and a cover communication hole 213 are formed inside the first purification plate 211.

[0179] The first coupling opening 212 is a space through which the purification module 400 passes. Specifically, the module body 410 coupled to the purification module 400 passes through the first coupling opening 212 .

[0180] The first coupling opening 212 is formed through the thickness of the first purification plate 211, connecting the housing space 14 with the first purification main space 312. This allows communication between the outside and the first purification main space 312. The purification module 400, which is coupled to the first coupling opening 212, can extend into the first purification main space 312.

[0181] The first coupling opening 212 can be sealed by the purification module 400. In other words, the first coupling opening 212, which passes through the purification module 400, is sealed, thereby isolating any communication between the outside and the first purification main body space 312. In other words, the purification module 400 is sealed and coupled at the first coupling opening 212. To this end, a member such as an O-ring (not shown) can be provided in the purification module 400.

[0182] Therefore, external fluid can flow into the first purification main space 312 through the hollow space formed inside the module main body 410 of the purification module 400 .

[0183] The first coupling opening 212 may be any shape that allows the purification module 400 to penetrate and couple therethrough. In the illustrated embodiment, the purification module 400, ie, the module body 410, has a circular cross-section, so the first coupling opening 212 also has a circular cross-section.

[0184] The first combination openings 212 may be formed in a plurality and may be spaced apart from each other. The purification modules 400 may be respectively connected to the first combination openings 212 .

[0185] In the illustrated embodiment, the first coupling openings 212 are adjacently arranged radially inward of each corner of the first purification plate 211. Here, a virtual line extending along the outermost plurality of first coupling openings 212 has a hexagonal shape.

[0186] In other words, the plurality of first combining openings 212 are arranged in a total of five rows (columns), with three first combining openings 212 formed in the top and bottom rows, four first combining openings 212 formed in the next top and bottom rows, and five first combining openings 212 formed in the center row.

[0187] In the embodiment, the plurality of first coupling openings 212 and the plurality of purification modules 400 passing therethrough can be evenly distributed in the left-right direction or the up-down direction. Therefore, the path of the fluid flowing into the interior of the housing 10 through the purification modules 400 can also be formed evenly relative to the cross-section of the first purification plate 211.

[0188] The number and arrangement of the plurality of first combining openings 212 may be changed.

[0189] The cover communication hole 213 connects the first purification main space 312, specifically the second space 312b, with the outside. The cover communication hole 213 extends through the thickness of the first purification plate 211, connecting the outside with the second space 312b. Foreign matter separated from the fluid during passage through the purification module 400 can be discharged to the outside via a suction device (not shown) inserted into the cover communication hole 213.

[0190] In particular, the power device 1 of the embodiment of the present invention has a connecting flow path 700 , described below, incorporated into the cover connecting hole 213 . Thus, the connecting flow path 700 communicates with the first purification main space 312 , allowing separated foreign matter to flow along the flow path 40 toward the discharge portion 30 .

[0191] The cover communication hole 213 may be any shape that can be inserted into the suction device (not shown). In the illustrated embodiment, the cover communication hole 213 is formed to have a circular cross section.

[0192] The cover communication hole 213 can be formed at any position that is combined with the communication flow path portion 700 and can connect the second space 312b with the outside. In the illustrated embodiment, the cover communication hole 213 is formed on the lower side of the first combination opening 212, that is, the second portion 211b of the first purification plate 211.

[0193] The second purification cover 220 is disposed facing the first purification cover 210 with the first purification body 310 interposed therebetween.

[0194] The second purification cover 220 forms a portion of the inner side of the purification unit 20. In the illustrated embodiment, the second purification cover 220 is located between the first purification body 310 and the second purification body 320, forming a middle portion of the purification unit 20.

[0195] The second purification cover 220 is disposed to face the first purification cover 210 across the first purification body 310. In addition, the second purification cover 220 is disposed to face the third purification body 330 across the second purification body 320.

[0196] The second purification cover 220 is coupled to the first purification body 310. Specifically, the second purification cover 220 covers the first purification body space 312 formed within the first purification body 310 from one side, i.e., the rear side in the illustrated embodiment, and is coupled to the first purification body 310. In one embodiment, the second purification cover 220 can be tightly coupled to the first purification body 310.

[0197] The second purification cover 220 is coupled to the second purification body 320. Specifically, the second purification cover 220 covers the second purification body space 322 formed inside the second purification body 320 from the other side, i.e., the front side in the illustrated embodiment, and is coupled to the second purification body 320. In one embodiment, the second purification cover 220 can be tightly coupled to the second purification body 320.

[0198] The second purification cover 220 is coupled to the purification module 400. The second purification cover 220 is configured to support the other portion of the purification module 400, namely, the rear portion in the illustrated embodiment. This is achieved by the purification module 400 being coupled through a second coupling opening 222 formed in the second purification cover 220. In the illustrated embodiment, a second vortex-forming member 430 is coupled to the second purification cover 220.

[0199] The second purification cover 220 can be of any shape, combined with the first purification body 310 and the second purification body 320, respectively, to seal the first purification body space 312 and the second purification body space 322, and to partially support the purification module 400. In the illustrated embodiment, the second purification cover 220 is a quadrilateral plate with four corners.

[0200] The second purification cover 220 is arranged to overlap with the first purification cover 210 and the purification body 300 along the thickness direction thereof, that is, the front-to-back direction in the illustrated embodiment.

[0201] In the illustrated embodiment, the second purge cover 220 includes a second plate 221 and a second coupling opening 222 .

[0202] The second plate 221 forms the main body of the second purification cover 220. The second plate 221 has a plate shape and is coupled to the first purification body 310 and the second purification body 320. The second plate 221 is configured to cover the first purification body space 312 formed within the first purification body 310 and the second purification body space 322 formed within the second purification body 320.

[0203] A plurality of through holes are formed inside the second plate 221. In the illustrated embodiment, a second coupling opening 222 is formed inside the second plate 221.

[0204] The second coupling opening 222 is a space through which the purification module 400 passes. Specifically, the second vortex forming member 430 coupled to the purification module 400 passes through the second coupling opening 222 .

[0205] The second opening 222 is formed through the thickness of the second plate 221 to connect the first purification main space 312 with the second purification main space 322. The purification module 400 connected to the second opening 222 can extend into the first purification main space 312 or the second purification main space 322.

[0206] The second joint opening 222 can be sealed by the purification module 400. In other words, the second joint opening 222, which passes through the purification module 400, is sealed, thereby cutting off the connection between the first purification main body space 312 and the second purification main body space 322. In other words, the purification module 400 is sealed and connected to the second joint opening 222. To this end, a sealing member (not shown) can be additionally provided in the purification module 400.

[0207] Therefore, the fluid flowing into the module body 410 of the purification module 400 can flow into the second purification main body space 322 only through the second vortex forming member 430 .

[0208] The second opening 222 can be any shape that can be penetrated by the purification module 400. In the illustrated embodiment, the purification module 400, that is, the boss portion 433 of the second vortex forming member 430 is formed to have a circular cross section, so the second opening 222 is also formed to have a circular cross section.

[0209] The second coupling openings 222 may be formed in a plurality and spaced apart from each other. The purification modules 400 may penetrate and be coupled to the second coupling openings 222 , respectively.

[0210] In the illustrated embodiment, the second coupling openings 222 are adjacently arranged radially inward of each corner of the second plate 221. Here, a virtual line extending along the outermost plurality of second coupling openings 222 has a hexagonal shape.

[0211] In other words, the plurality of second combining openings 222 are arranged in a total of five rows (columns), with three second combining openings 222 formed in the top and bottom rows, four second combining openings 222 formed in the next top and bottom rows, and five second combining openings 222 formed in the center row.

[0212] In the embodiment, the plurality of second coupling openings 222 and the plurality of purification modules 400 passing therethrough can be evenly distributed in the left-right direction or the up-down direction. Therefore, the path of the fluid flowing into the interior of the housing 10 through the purification modules 400 can also be formed evenly relative to the cross-section of the second plate 221.

[0213] It is understood that the number and arrangement of the plurality of second coupling openings 222 described above correspond to the number and arrangement of the plurality of first coupling openings 212. The plurality of second coupling openings 222 and the plurality of first coupling openings 212 can be arranged to overlap along the thickness direction of the purification cover 200, i.e., the front-to-back direction in the illustrated embodiment.

[0214] The number and arrangement of the plurality of second coupling openings 222 may be changed according to the number and arrangement of the plurality of first coupling openings 212 .

[0215] The purification cover 200 is combined with the purification body 300 .

[0216] The purification body 300 forms another portion of the outer shape of the purification unit 20. A space is formed within the purification body 300, communicating with the through-holes of the purification cover 200. This space can accommodate the purification module 400 or allow fluid passing through the purification module 400 to flow. In other words, the purification body 300 forms both a space for accommodating the purification module 400 and a space for fluid to flow.

[0217] The purification body 300 is combined with the purification cover 200. The purification body 300 forms a space therebetween and is combined with the purification cover 200. The purification module 400 may be accommodated in the space or a fluid having passed through the purification module 400 may flow therethrough.

[0218] The purification body 300 can be tightly coupled to the purification cover 200. Specifically, the space between the purification body 300 and the purification cover 200 can be sealed by the purification body 300 and the purification cover 200, thereby cutting off any external communication. Therefore, as described above, external fluid can only flow into the space between the purification body 300 and the purification cover 200 after passing through the purification module 400.

[0219] The purification body 300 is arranged to overlap the purification cover 200 along its thickness direction, that is, the front-to-back direction in the illustrated embodiment. In addition, the purification body 300 partially accommodates the purification module 400 therein.

[0220] There may be a plurality of purification bodies 300. The plurality of purification bodies 300 may be combined with a plurality of purification covers 200 and purification modules 400, respectively. Figures 1 to 4In the illustrated embodiment, there are four purification bodies 300 , which are respectively combined with four purification covers 200 and four groups of purification modules 400 .

[0221] In the illustrated embodiment, the purification body 300 includes a first purification body 310 , a second purification body 320 , a third purification body 330 , and a suction fan 340 .

[0222] The first purification body 310 is located between the first purification cover 210 and the second purification cover 220, and is respectively coupled to the first purification cover 210 and the second purification cover 220. The second purification body 320 is located between the second purification cover 220 and the third purification body 330, and is respectively coupled to the second purification cover 220 and the third purification body 330. The third purification body 330 is located between the second purification body 320 and the suction fan 340, and is respectively coupled to the second purification body 320 and the suction fan 340.

[0223] Therefore, it can be understood that the purification cover 200 and the purification body 300 are alternately arranged with each other along the stacking direction thereof.

[0224] The first purification body 310 forms part of the purification section 20. Furthermore, the first purification body 310 forms part of the purification body 300. In the illustrated embodiment, the first purification body 310 is located between the first purification cover 210 and the second purification cover 220, forming the front side of the purification body 300. In other words, the first purification body 310 is positioned closest to the first outer surface 11 of the purification body 300.

[0225] The first purification body 310 is coupled to the first purification cover 210. Specifically, the space formed inside the first purification body 310 (i.e., the first purification body space 312) is covered by and coupled to the first purification cover 210. In one embodiment, the first purification body 310 can be tightly coupled to the first purification cover 210.

[0226] The first purification body 310 is combined with the second purification cover 220. Specifically, the first purification body space 312 formed inside the first purification body 310 is covered and combined with the second purification cover 220. In one embodiment, the first purification body 310 and the second purification cover 220 can also be tightly combined.

[0227] That is, the first purification body 310 is disposed between the first purification cover 210 and the second purification cover 220. The first purification body 310 is disposed so as to overlap with the first purification cover 210 and the second purification cover 220.

[0228] The first purification body 310 partially accommodates the purification module 400. Specifically, the first purification body 310 accommodates a portion of the module body portion 410 and a portion of the second vortex forming member 430 in a first purification body space 312 formed therein.

[0229] The first purification body 310 can be any shape that is combined with the first purification cover 210 and the second purification cover 220, accommodates the purification module 400, and can cut off any communication between its internal space and the outside. In the illustrated embodiment, similar to the first purification cover 210, the first purification body 310 is formed to have a polygonal cross-section with multiple corners and a thickness in the front-to-back direction.

[0230] Due to the shape of the first purification body 310, foreign matter and the like separated from the fluid passing through the purification module 400 can be captured on one side of the interior of the first purification body 310. Furthermore, the captured foreign matter and the like can pass through the flow path 40 and be discharged to the outside via the discharge unit 30. This will be described in detail later.

[0231] In the illustrated embodiment, the first purification body 310 includes a first purification module body periphery 411 , a first purification body space 312 , a purification body communication hole 313 , and a purification body cap 314 .

[0232] The first purification module body periphery 411 forms the outer shape of the first purification body 310. The first purification module body periphery 411 surrounds the first purification body space 312 from the outside. In other words, the first purification module body periphery 411 can be defined as the outer surface of the first purification body 310.

[0233] The outer periphery of the first purification module body 411 can be divided into a plurality of sections. The plurality of sections are continuous with each other, and the outer periphery of the first purification module body 411 can form a closed loop. In the illustrated embodiment, the outer periphery of the first purification module body 411 includes a first section arranged on the upper side and formed into a hexagonal cross-sectional shape, and a second section arranged on the lower side and formed into a quadrilateral cross-sectional shape.

[0234] The first portion is configured to surround a first space 312 a of the first purification main body space 312 , and the second portion is configured to surround a second space 312 b of the first purification main body space 312 .

[0235] As described above, due to the shape of the first portion, the plurality of purification modules 400 can be arranged in equal numbers along the extension direction of the first purification module body outer periphery 411 , thereby allowing external fluid to flow into the plurality of purification modules 400 evenly.

[0236] In this case, the lateral portions of the corners of the first portion, i.e., the left and right portions in the illustrated embodiment, which are continuous with the second portion (the lower portion in the illustrated embodiment), preferably extend downwardly in an inclined direction. Due to this shape, foreign matter that flows into the first space 312a can fall and be captured in the second space 312b without being retained in the first portion.

[0237] A purification body communication hole 313 may be formed on the outer periphery 411 of the first purification module body. The purification body communication hole 313 may be opened and closed by a purification body cap 314, thereby allowing or blocking communication between the first purification body space 312 and the outside.

[0238] The space surrounded by the outer periphery 411 of the first purification module body is defined as the first purification body space 312 .

[0239] The first purification body space 312 is a space formed inside the first purification body 310. The purification module 400 is partially accommodated in the first purification body space 312. In addition, foreign matter separated from the purification module 400 can be accommodated in the first purification body space 312.

[0240] The first purification main body space 312 is surrounded and defined by the first purification module main body outer periphery 411. In the illustrated embodiment, the first purification main body space 312 is formed as a space having a polygonal cross-section formed radially inside the first purification module main body outer periphery 411.

[0241] The thickness direction of the first purification main body space 312 can be enclosed by the first purification cover 210 and the second purification cover 220. That is, in the illustrated embodiment, the front side of the first purification main body space 312 is enclosed by the first purification cover 210. In addition, the rear side of the first purification main body space 312 is enclosed by the second purification cover 220.

[0242] The first purification main body space 312 is connected to the purification module 400. Specifically, the first purification main body space 312 is connected to the module body hollow space 413 through a dust exhaust portion 416 formed in the purification module 400. Foreign matter and the like separated from the fluid flowing through the purification module 400 can flow into the first purification main body space 312 through the dust exhaust portion 416.

[0243] The first purification main body space 312 is connected to the exhaust unit 30. Specifically, the first purification main body space 312 is connected to the exhaust fan assembly 600 via the communication flow path 700 and the exhaust flow path 800. Foreign matter and the like trapped in the first purification main body space 312 can be discharged outside the power equipment 1 through the exhaust fan assembly 600 and the exhaust frame 500.

[0244] The first purification body space 312 can be connected or disconnected with the cover body space 14. Specifically, the first purification body space 312 can be connected to the cover body space 14 through the purification body connecting hole 313. If the purification body cap 314 is inserted and coupled to the purification body connecting hole 313, the connection between the first purification body space 312 and the cover body space 14 can be cut off.

[0245] The first purification main space 312 can be divided into a plurality of spaces. In the illustrated embodiment, the first purification main space 312 includes a first space 312a located at the upper side and having a hexagonal cross-section, and a second space 312b located at the lower side and communicating with the first space 312a and having a quadrangular cross-section.

[0246] First space 312a partially houses purification module 400. Specifically, first space 312a houses a portion of module body 410. First space 312a communicates with module body hollow space 413 via dust exhaust 416, allowing separated foreign matter to flow into first space 312a. First space 312a communicates with second space 312b.

[0247] The first space 312a can communicate with the outside through the purification body communication hole 313. A component for cleaning the first space 312a, such as a blower, can enter the first space 312a through the purification body communication hole 313.

[0248] Second space 312b accommodates foreign matter that has flowed into and fallen from first space 312a. Second space 312b is connected to first space 312a and is located below first space 312a. Therefore, even without applying any external force, foreign matter that has flowed into first space 312a can fall due to its own weight and be captured in second space 312b.

[0249] The second space 312b can communicate with the outside through the cover communication hole 213. A member for removing foreign matter trapped in the second space 312b, such as a suction member, can enter the second space 312b through the cover communication hole 213.

[0250] The purification body connecting hole 313 connects the first purification body space 312 with the outside. The purification body connecting hole 313 is formed through the outer periphery 411 of the first purification module body.

[0251] The purification body connecting hole 313 can be formed at any position that can connect the first purification body space 312 with the outside. In the illustrated embodiment, the purification body connecting hole 313 is formed in the upper part of the first part of the first purification module body outer periphery 411, that is, the part extending obliquely toward the lower side and the outside.

[0252] In the embodiment, a blower or the like penetrating the purification body communication hole 313 may spray the fluid for cleaning from the upper portion toward the lower portion of the first space 312 a .

[0253] The purification body communication hole 313 may be any shape that can connect the first purification body space 312 with the outside. In the illustrated embodiment, the purification body communication hole 313 is formed to have a circular cross-section.

[0254] The purification body connecting holes 313 may be formed in a plurality. The plurality of purification body connecting holes 313 may be formed at different locations, respectively connecting the first purification body space 312 with the outside. In the illustrated embodiment, the purification body connecting holes 313 include a first connecting hole 313a formed on the left side and a second connecting hole 313b formed on the right side.

[0255] The purification body cap 314 may be inserted and coupled to the purification body communication hole 313 in a removable manner.

[0256] The purification body cap 314 is coupled to the purification body communicating hole 313 to seal the purification body communicating hole 313. Thus, the communication between the first purification body space 312 and the outside can be cut off.

[0257] The purification body cap 314 can be inserted and coupled to the purification body communication hole 313 in a removable manner. In other words, the purification body cap 314 can be detachably coupled to the purification body communication hole 313.

[0258] The purification body cap 314 can be formed from a predetermined deformable material. This is to store restoring force through the deformation of the purification body cap 314 and to maintain a stable connection with the purification body connecting hole 313. In one embodiment, the purification body cap 314 can be formed from a rubber material.

[0259] The purification body cap 314 may have any shape that can be inserted and coupled to the purification body communication hole 313. In the illustrated embodiment, the purification body cap 314 has a circular cross-section according to the shape of the purification body communication hole 313 and is formed to extend in one direction.

[0260] There may be a plurality of purification body caps 314. The plurality of purification body caps 314 may be detachably coupled to the plurality of purification body communication holes 313. In the illustrated embodiment, the purification body caps 314 include a first cap 314a inserted into the first communication hole 313a and a second cap 314b inserted into the second communication hole 313b.

[0261] The second purification body 320 forms another part of the purification unit 20. In addition, the second purification body 320 forms another part of the purification body 300. In the illustrated embodiment, the second purification body 320 is located between the second purification cover 220 and the third purification body 330, forming the central part of the purification body 300.

[0262] The second purification body 320 is coupled to the second purification cover 220. Specifically, the space formed inside the second purification body 320 (i.e., the second purification body space 322) is covered by and coupled to the second purification cover 220. In one embodiment, the second purification body 320 can be tightly coupled to the second purification cover 220.

[0263] The second purification body 320 is coupled to the third purification body 330. Specifically, the second purification body 320 and the third purification body 330 are coupled so that the second purification body space 322 formed within the second purification body 320 communicates with the purification cavity 331 formed within the third purification body 330. In one embodiment, the second purification body 320 and the third purification body 330 may also be tightly coupled.

[0264] That is, the second purification body 320 is disposed between the second purification cover 220 and the third purification body 330. The second purification body 320 is disposed so as to overlap with the second purification cover 220 and the third purification body 330.

[0265] The second purification body 320 partially accommodates the purification module 400. Specifically, the second purification body 320 accommodates a portion of the second vortex flow forming member 430 in a second purification body space 322 formed therein.

[0266] The second purification body 320 is in communication with the purification module 400 . The fluid from which foreign matter and the like are separated when passing through the purification module 400 can flow into the second purification body space 322 .

[0267] The second purification body 320 is connected to the third purification body 330. The fluid flowing into the second purification body space 322 can be discharged to the outside of the purification unit 20 through the purification cavity 331, thereby cooling the components installed in the power equipment 1.

[0268] The second purification body 320 can be of any shape, combined with the second purification cover 220 and the third purification body 330, and connected to the purification module 400, capable of guiding the incoming fluid into the purification cavity 331. Furthermore, the second purification body 320 can be of any shape, as long as any connection between its interior and the exterior can be cut off. In the illustrated embodiment, similar to the first portion 211a of the second purification cover 220, the second purification body 320 is formed to have a hexagonal cross-section and a thickness in the front-to-back direction.

[0269] Due to the shape of the second purification body 320, the fluid passing through the purification module 400 coupled to the first portion 211a of the second purification cover 220 can flow into the second purification body space 322. This will be described in detail later.

[0270] In the illustrated embodiment, the second purification body 320 includes a second purification body outer periphery 321 and a second purification body space 322 .

[0271] The second purification body outer periphery 321 forms the outer shape of the second purification body 320. The second purification body outer periphery 321 is formed to surround the second purification body space 322 from the outside. In other words, the second purification body outer periphery 321 can be defined as the outer surface of the second purification body 320.

[0272] The outer periphery of the second purification body 321 can be divided into a plurality of sections. The plurality of sections are continuous with each other, so that the outer periphery of the second purification body 321 can form a closed loop. In the illustrated embodiment, the outer periphery of the second purification body 321 is formed to have a hexagonal cross-section.

[0273] The shape of the second purification body outer periphery 321 may correspond to the shape of the first portion 211a of the second purification cover 220 coupled with the purification module 400. Thus, the fluid separated from foreign matter and the like when passing through the purification module 400 may flow uniformly into the second purification body space 322.

[0274] The space surrounded by the second purification body outer periphery 321 is defined as the second purification body space 322 .

[0275] The second purification body space 322 is a space formed inside the second purification body 320. The purification module 400 is partially accommodated in the second purification body space 322. The fluid that has passed through the purification module 400 (i.e., the fluid from which foreign matter and the like have been removed) can flow in the second purification body space 322.

[0276] The second purification body space 322 is surrounded and defined by the second purification body outer periphery 321. In the illustrated embodiment, the second purification body space 322 is formed as a space having a polygonal cross-section formed radially inside the second purification body outer periphery 321.

[0277] One side of the second purification main body space 322 in the thickness direction may be closed by the second purification cover 220 . In the illustrated embodiment, the front side of the second purification main body space 322 is closed by the second purification cover 220 .

[0278] The other side of the second purification body space 322 in the thickness direction may be covered by the third purification body 330 . In the illustrated embodiment, the rear side of the second purification body space 322 is partially closed by the third purification body 330 .

[0279] The second purification main body space 322 is communicated with the second vortex forming member 430 provided in the purification module 400 . The fluid from which foreign matter and the like have been removed can flow into the second purification main body space 322 through the second vortex forming member 430 .

[0280] The second purification main body space 322 is in communication with the purification module 400. Specifically, the second purification main body space 322 is in communication with the module main body hollow space 413 of the purification module 400 through the vortex hollow space 434 of the second vortex forming member 430. The fluid from which foreign matter and the like are removed can flow into the second purification main body space 322 through the vortex hollow space 434.

[0281] Although not shown, a filter element (not shown) can be provided in the second purification main space 322 to further filter the fluid, such as foreign matter. In this case, the fluid can flow into the second purification main space 322 after the foreign matter has been centrifuged. Therefore, relatively large foreign matter particles will not remain in the filter element (not shown), thereby increasing the durability of the filter element (not shown).

[0282] The third purification body 330 forms another portion of the purification unit 20. Furthermore, the third purification body 330 forms the remainder of the purification body 300. In the illustrated embodiment, the third purification body 330 is located between the second purification body 320 and the suction fan 340, forming the rear portion of the purification body 300.

[0283] The third purification body 330 is coupled to the second purification body 320. Specifically, the third purification body 330 is coupled to the second purification body 320 so that a purification cavity 331 formed within the third purification body 330 covers the second purification body space 322. The purification cavity 331 is connected to the second purification body space 322. In one embodiment, the third purification body 330 can be tightly coupled to the second purification body 320.

[0284] The third purification body 330 is combined with the suction fan 340. The third purification body 330 can communicate with the suction fan 340 to form a fluid discharge path. The third purification body 330 is located between the second purification body 320 and the suction fan 340.

[0285] The third purification body 330 can be any shape that can be combined with and communicate with the second purification body 320 and the suction fan 340. In the illustrated embodiment, the third purification body 330 is a hexagonal plate having a cross-section similar to the outer periphery 321 of the second purification body.

[0286] In the illustrated embodiment, the third purification body 330 includes a purification hollow 331 .

[0287] The purification cavity 331 is a space formed inside the third purification body 330. The purification cavity 331 extends through the thickness of the third purification body 330, that is, the front-to-back direction in the illustrated embodiment. The purification cavity 331 connects the second purification body space 322 with the suction fan 340.

[0288] The purification cavity 331 may be any shape that can connect the second purification main space 322 and the suction fan 340. In the illustrated embodiment, the purification cavity 331 is formed as a disk-shaped space having a circular cross-section and a thickness in the front-to-back direction.

[0289] The suction fan 340 provides a conveying force that allows external fluid to be discharged through the housing space 14 and the purification module 400 through the suction fan 340. The suction fan 340 is coupled to the third purification body 330. The suction fan 340 is arranged to face the second purification body 320 across the third purification body 330. In other words, the suction fan 340 is arranged farthest from the first outer surface 11.

[0290] The suction fan 340 is connected to the housing space 14, the second purification main space 322 and the purification module 400. Specifically, the suction fan 340 is connected to the second purification main space 322 through the purification cavity 331, thereby connecting to the purification module 400 and the housing space 14.

[0291] The suction fan 340 may be any type that can provide a conveying force for causing the external fluid to flow into the electric power device 1. In one embodiment, the suction fan 340 may be provided in the form of a sirocco fan.

[0292] In order to control the operation of the suction fan 340 , the suction fan 340 may be electrically connected to a power source (not shown) or a control unit (not shown).

[0293] Refer again Figure 7 and Figure 8 , the power equipment 1 of the embodiment of the present invention includes a purification module 400 .

[0294] The purification module 400 separates and removes foreign matter mixed in the external fluid. In one embodiment, due to the purification module 400, relatively large-sized particles in the dust mixed in the fluid can be separated.

[0295] Therefore, the blockage of the fluid inflow path caused by the large-sized particles is prevented, and the external fluid can flow smoothly in. As a result, the components provided in the electric power equipment 1 can be cooled effectively.

[0296] The purification module 400 may be any type that can separate and remove foreign matter mixed in the fluid. In the illustrated embodiment, the purification module 400 is configured to separate and remove foreign matter mixed in the fluid by centrifugal separation.

[0297] Specifically, when the fluid flows in a vortex, particles mixed in the fluid are subjected to centrifugal force and move radially outward. These moving particles can be discharged outside the purification module 400 and captured inside the purification body 300. Furthermore, particles captured inside the purification body 300, i.e., foreign matter separated from the fluid, can pass through the flow path 40 and be discharged outside the power device 1 via the discharge unit 30.

[0298] The purification module 400 is combined with the purification cover 200. Specifically, the purification module 400 is respectively combined with the first purification cover 210 and the second purification cover 220. As described above, the first purification cover 210 and the second purification cover 220 are arranged facing each other with the first purification body 310 interposed therebetween and are spaced apart from each other.

[0299] Therefore, it can be understood that the purification module 400 penetrates the first purification body 310 and extends between the first purification cover 210 and the second purification cover 220. In the illustrated embodiment, the purification module 400 is formed to extend in the front-to-back direction.

[0300] One end of the purification module 400 in the extending direction, i.e., the front end in the illustrated embodiment, is exposed to the outside (i.e., the front side) of the first purification cover 210 and communicates with the cover space 14. External fluid can flow into the interior of the purification module 400 through the cover space 14 and the opening formed at the end of the purification module 400.

[0301] The other end of the purification module 400 in the extending direction, i.e., the rear end in the illustrated embodiment, is exposed to the rear side of the second purification cover 220 and communicates with the second purification main body space 322. After foreign matter and the like are removed, external fluid can flow into the second purification main body space 322 through the opening formed in the end of the purification module 400.

[0302] The purification module 400 extends inside the first purification main body space 312. The purification module 400 extends along the thickness direction of the first purification main body space 312, that is, the front-to-back direction in the illustrated embodiment.

[0303] The purification module 400 is in communication with the first purification main body space 312. Due to the purification module 400, foreign matter and the like separated from the fluid can be discharged into the first purification main body space 312. This will be described in detail later.

[0304] There may be a plurality of purification modules 400. The plurality of purification modules 400 may be coupled to the plurality of first coupling openings 212 formed in the first purification cover 210 and the plurality of second coupling openings 222 formed in the second purification cover 220, respectively. To this end, the plurality of first coupling openings 212 and the plurality of second coupling openings 222 may be arranged on the same line along the extension direction of the purification module 400.

[0305] The number of purification modules 400 can be varied. That is, the number of purification modules 400 can be varied according to the amount of heat generated by the operation of the power equipment 1. In this case, the number of first and second coupling openings 212 and 222 formed in the first and second purification covers 210 and 220, respectively, can also be varied according to the number of purification modules 400.

[0306] Alternatively, the number of the first and second openings 212 and 222 may be greater than the number of the purification modules 400. In the embodiment, the first or second openings 212 and 222 not connected to the purification module 400 may be sealed by a sealing member (not shown).

[0307] In the illustrated embodiment, the purification module 400 includes a module body 410 , a first vortex flow forming member 420 , and a second vortex flow forming member 430 .

[0308] The module body 410 forms the main body of the purification module 400. A space communicating with the outside is formed inside the module body 410. External fluid can flow through the space and be separated from mixed foreign matter.

[0309] The module body 410 extends in a direction that can be defined as the same direction in which the purification cover 200 and the purification body 300 are stacked. In the illustrated embodiment, the module body 410 extends in a front-to-back direction.

[0310] One side of the module body 410's extension direction is coupled to the first purge cover 210. In the illustrated embodiment, the front side of the module body 410 extends through the first coupling opening 212 of the first purge cover 210 and couples to it. The front end of the module body 410 is exposed to the outside of the first purge cover 210, allowing external fluid to flow into the module body 410.

[0311] The other side of the module body 410 in the extending direction is connected to the second purification cover 220. In the illustrated embodiment, the rear side of the module body 410 is connected to the second plate 221 of the second purification cover 220 via the second vortex forming member 430. Therefore, the rear end of the module body 410 is closed by the second vortex forming member 430.

[0312] The rest of the module body 410 is housed in the first purification body space 312 of the first purification body 310. The interior space of the module body 410 communicates with the first purification body space 312 via a dust discharger 416 to be described later.

[0313] The module body 410 can be any shape that allows fluid to flow through the first and second purge covers 210 and 220, respectively. In the illustrated embodiment, the module body 410 has a cylinder shape with a hollow, ring-shaped cross-section formed inside and extending in the front-to-back direction. The shape of the module body 410 can be changed depending on the shapes of the first and second coupling openings 212 and 222.

[0314] In the illustrated embodiment, the module body portion 410 includes a module body outer periphery 411 , a module body inner periphery 412 , a module body hollow 413 , a first module body end 414 , a second module body end 415 , a dust discharge portion 416 , and a guide protrusion 417 .

[0315] The module body periphery 411 forms the periphery of the module body portion 410. The module body periphery 411 can be defined as the outer surface of the module body portion 410. As described above, the module body portion 410 is a cylindrical shape with a hollow interior, and the module body periphery 411 can be referred to as the side surface of the module body portion 410.

[0316] The module body outer periphery 411 is the portion where the module body 410 and the first purge cover 210 are joined. If the module body 410 extends through the first joining opening 212, the module body outer periphery 411 can be tightly joined to the inner circumference surrounding the first joining opening 212. To this end, the outer diameter of the module body outer periphery 411 and the inner diameter of the first joining opening 212 can be the same.

[0317] The module body inner periphery 412 forms the inner periphery of the module body portion 410. The module body inner periphery 412 may be defined as an inner surface of the module body portion 410.

[0318] The module body inner periphery 412 is the portion where the module body portion 410 and the first vortex forming member 420 are combined. Figure 14 and Figure 15 As shown, the radial end of the first vortex flow forming member 420 may be coupled to the module body inner circumference 412. That is, it can be understood that the module body inner circumference 412 supports the first vortex flow forming member 420.

[0319] The module body hollow space 413 is a space formed inside the module body portion 410. The module body hollow space 413 may be defined as a space surrounded by the module body inner periphery 412.

[0320] The module body hollow space 413 extends along the direction in which the module body portion 410 extends. In the illustrated embodiment, the module body hollow space 413 extends in the front-to-back direction. Each end of the module body hollow space 413 in the extension direction, namely, the front end and the rear end in the illustrated embodiment, are open. In other words, the module body hollow space 413 is formed within the module body portion 410 and extends through the module body portion 410 in the extension direction.

[0321] The module body hollow space 413 is connected to the outside through the front end portion, and external fluid can flow into the module body hollow space 413 through the front end portion of the module body hollow space 413 .

[0322] The rear end of the module body hollow space 413 is sealed by the second vortex forming member 430. The fluid flowing into the module body hollow space 413 can flow in the form of a vortex when passing through the first vortex forming member 420, then flow in the opposite direction after colliding with the second vortex forming member 430, and then flow into the second purification main space 322 through the second vortex forming member 430.

[0323] The module body hollow 413 is connected to the first purification main space 312. Specifically, the module body hollow 413 is connected to the module body hollow 413 through the dust discharge portion 416, and foreign matter separated from the fluid can be discharged into the first purification main space 312.

[0324] The first vortex forming member 420 is accommodated in the hollow space 413 of the module body. Figure 14 and Figure 15 In the illustrated embodiment, the first vortex forming member 420 is disposed adjacent to the outer side of the hollow portion 413 of the module body, ie, the front end portion.

[0325] The second vortex forming member 430 is housed in the hollow portion 413 of the module body. Figure 21 and Figure 22 The second vortex forming member 430 is arranged behind the module body hollow 413 and spaced apart from the module body inner circumference 412. Therefore, the diameter of the module body hollow 413, that is, the diameter of the module body inner circumference 412, can be formed to be larger than the outer diameter of the second vortex forming member 430.

[0326] The module body hollow space 413 may be of any shape suitable for accommodating the first vortex-forming member 420 and forming a passage for separating foreign matter and the like from the fluid and for allowing the fluid to flow. In the illustrated embodiment, the module body hollow space 413 is formed as a cylindrical space having a circular cross-section and extending in the front-to-rear direction.

[0327] The first module body end portion 414 forms one end portion of the module body portion 410 in the extending direction. In the illustrated embodiment, the first module body end portion 414 forms a front end portion of the module body portion 410 extending in the front-rear direction.

[0328] The first module body end portion 414 is exposed to the outside of the first purge cover 210. In the illustrated embodiment, the first module body end portion 414 is exposed to the front side of the first purge cover 210.

[0329] The first module body end portion 414 is configured to surround one side of the module body hollow portion 413, i.e., the front end in the illustrated embodiment. External fluid can flow into the interior of the module body portion 410 through the end of the module body hollow portion 413 surrounded by the first module body end portion 414.

[0330] The second module body end portion 415 forms the other end portion of the module body portion 410 in the extending direction. In the illustrated embodiment, the second module body end portion 415 forms the rear end portion of the module body portion 410 extending in the front-rear direction.

[0331] The second module body end portion 415 is accommodated in the first purification body space 312 . In addition, the second module body end portion 415 is coupled to the second vortex flow forming member 430 .

[0332] The dust discharge portion 416 connects the module body hollow 413 and the first purification main body space 312 . Foreign matter and the like separated from the fluid can be discharged into the first purification main body space 312 through the dust discharge portion 416 .

[0333] The dust discharge portion 416 is formed through a portion of the module body outer periphery 411 and the module body inner periphery 412. Figure 14 and Figure 15 The dust discharge portion 416 is formed at the lower portion behind the module body outer periphery 411 and the module body inner periphery 412 .

[0334] Therefore, foreign matter and the like centrifugally separated from the fluid flowing in the vortex form in the module body hollow 413 can be discharged into the first purification main body space 312 through the dust discharge portion 416 formed on the lower rear side.

[0335] The dust discharge portion 416 may be any shape that can connect the module body hollow 413 and the first purification body space 312. In the illustrated embodiment, the dust discharge portion 416 is formed in an arc shape extending along the module body outer circumference 411 and the module body inner circumference 412.

[0336] The process in which the separated foreign matter and the like are discharged into the first purification main body space 312 through the dust discharge unit 416 and the foreign matter and the like contained in the first purification main body space 312 are discharged into the discharge unit 30 will be described in detail later.

[0337] The guide protrusion 417 limits the distance the module body 410 can be inserted into the purification cover 200 and the purification body 300. In other words, the guide protrusion 417 is configured to limit the distance the module body 410 can move toward the rear. Therefore, the module body 410 can only be inserted until the second module body end 415 is in close contact with the second vortex-forming member 430.

[0338] The guide protrusions 417 are formed on the module body outer periphery 411. The guide protrusions 417 protrude radially outward from the module body outer periphery 411 and extend circumferentially. Thus, the outer diameter of the guide protrusions 417 is larger than both the outer diameter of the module body outer periphery 411 and the inner diameter of the first coupling opening 212.

[0339] Therefore, as the insertion of the module body part 410 proceeds, the guide protrusion 417 comes into contact with the first purification plate 211 , so that the coupling length of the purification module 400 may be limited.

[0340] The first vortex forming member 420 causes the fluid flowing into the module body hollow 413 to flow in a vortex form. The inflowing fluid forms a vortex under the action of the first vortex forming member 420 and flows, so that mixed foreign matter and the like can be centrifugally separated.

[0341] The first vortex flow forming member 420 is accommodated in the interior of the module body portion 410. Specifically, the first vortex flow forming member 420 is accommodated in the module body hollow 413.

[0342] The first vortex-forming member 420 can be positioned toward one end of the module body hollow space 413. In the illustrated embodiment, the first vortex-forming member 420 is positioned toward the front end of the module body hollow space 413. Thus, the first vortex-forming member 420 can be positioned so as to be exposed to the outside. In other words, the first vortex-forming member 420 is positioned upstream of the flow of the fluid formed within the module body 410.

[0343] The end portion serves as an inlet for external fluid to flow into the hollow portion 413 of the module body, so that the external fluid flowing in may flow in the form of a vortex when passing through the first vortex forming member 420 .

[0344] The first vortex flow forming member 420 is coupled to the module body 410 . Specifically, each end portion of the first vortex flow forming member 420 in the radiation direction, ie, each end portion of a blade 422 to be described later, is coupled to the module body inner circumference 412 .

[0345] The first vortex forming member 420 may be in any form that can form the flow of the passing fluid into a vortex. In the illustrated embodiment, the first vortex forming member 420 is in the form of a vane.

[0346] In the illustrated embodiment, the first vortex forming member 420 includes a vortex shaft 421 and vanes 422 .

[0347] The vortex shaft 421 forms the center of the first vortex forming member 420. The vortex shaft 421 is combined with the plurality of blades 422 to form a portion of a path of the fluid passing through the first vortex forming member 420.

[0348] The vortex axis 421 can extend along the extension direction of the module body 410, that is, the front-to-back direction in the illustrated embodiment. The vortex axis 421 can extend along the central axis of the module body 410. Therefore, it can be understood that the vortex axis 421 is disposed along the central axis of the first and second joint openings 212, 222.

[0349] The blades 422 are coupled along the radial direction of the vortex axis 421 .

[0350] The blades 422 substantially form a vortex in the fluid flowing through the first vortex forming member 420. The blades 422 are respectively coupled to the vortex axis 421 and the module body inner circumference 412. That is, the blades 422 extend between the vortex axis 421 and the module body inner circumference 412.

[0351] The blades 422 may be formed so that their outer surfaces have a curved shape. The curved surface may be formed to have different curvatures along the extension direction of the module body 410, that is, the front-to-back direction in the illustrated embodiment. This allows the inflowing fluid to flow in a vortex shape.

[0352] There may be a plurality of blades 422. The plurality of blades 422 may be spaced apart from each other along the circumferential direction of the vortex axis 421. The plurality of blades 422 may form the flow of the fluid passing therethrough into a vortex shape.

[0353] The flow of the fluid passing through the first vortex flow forming member 420 and the separation process of foreign matter and the like will be described in detail later.

[0354] The second vortex forming member 430 reshapes the flow of the fluid formed by the first vortex forming member 420 (i.e., the flow in a vortex shape) and discharges the fluid into the second purification main body space 322. Due to the second vortex forming member 430, the vortex flow of the fluid is strengthened, thereby further effectively centrifuging mixed foreign matter and the like.

[0355] The second vortex flow forming member 430 is accommodated in the interior of the module body portion 410. Specifically, the second vortex flow forming member 430 is accommodated in the module body hollow 413.

[0356] The second vortex-forming member 430 can be positioned toward the other end of the module body hollow space 413. In the illustrated embodiment, the second vortex-forming member 430 is positioned toward the rear end of the module body hollow space 413. Thus, the second vortex-forming member 430 is not exposed to the outside. In other words, the second vortex-forming member 430 is positioned downstream of the flow of the fluid formed within the module body 410.

[0357] The end portion may be defined as the downstream end of the fluid flowing in the module body hollow 413. Therefore, the fluid flowing in the module body hollow 413 may collide with the second vortex forming member 430 at the other end portion and flow back upstream, and then flow into the second purification main body space 322 through the vortex hollow 434 formed inside the second vortex forming member 430.

[0358] The second vortex forming member 430 is coupled to the second purification cover 220. Specifically, one end portion of the second vortex forming member 430 in the extending direction, ie, the rear end portion in the illustrated embodiment, is inserted into the second coupling opening 222 of the second purification cover 220.

[0359] At this time, the second vortex forming member 430 can tightly connect the second connection opening 222 . Therefore, the fluid flowing in the module body hollow 413 can flow into the second purification main body space 322 only after passing through the vortex hollow 434 .

[0360] The second vortex forming member 430 can be arranged to have the same central axis as the central axis of the module body 410. Furthermore, the second vortex forming member 430 is spaced apart from the module body inner periphery 412. In other words, the maximum outer diameter of each component of the second vortex forming member 430 is smaller than the inner diameter of the module body inner periphery 412.

[0361] Therefore, a space in which the fluid can flow in a vortex form is formed between the outer peripheral surface of the second vortex flow forming member 430 and the inner periphery 412 of the module body.

[0362] The second vortex forming member 430 may be any shape capable of forming a vortex in the fluid flowing in the space separated from the module body inner periphery 412. In the illustrated embodiment, the second vortex forming member 430 is in the shape of a circular truncated cone whose diameter decreases toward the first vortex forming member 420, i.e., toward the front side.

[0363] In the illustrated embodiment, the second vortex flow forming member 430 includes a base 431 , a neck 432 , a boss portion 433 , and a vortex flow hollow portion 434 .

[0364] The base 431 forms a portion of the second vortex flow forming member 430. The base 431 is a portion where the second vortex flow forming member 430 and the second purification cover 220 are combined.

[0365] The base 431 is a portion where the module body 410 and the second vortex forming member 430 are connected. The base 431 supports the second module body end 415 of the module body 410, ie, the rear end in the illustrated embodiment.

[0366] The base 431 can be any shape that is combined with the second purification cover 220 and the module body 410 and can support them. In the illustrated embodiment, the base 431 is formed into a circular plate with a circular cross-section and a thickness in the extension direction of the module body 410, that is, the front-to-back direction.

[0367] The base 431 is continuous with the neck 432. The neck 432 is formed to extend from one side of the base 431, ie, the front side in the illustrated embodiment, toward a direction opposite to the base 431, ie, the front side.

[0368] The module body 410 is mounted on the base 431. The module body inner periphery 412 is spaced apart from the neck outer periphery 432a of the neck 432. That is, the module body 410 is mounted on the base 431 so that the module body inner periphery 412 radially surrounds the neck outer periphery 432a.

[0369] In the illustrated embodiment, the base 431 includes a first base surface 431 a and a second base surface 431 b .

[0370] The first seating surface 431 a forms one side of the base 431 . In the illustrated embodiment, the first seating surface 431 a forms the front side of the base 431 .

[0371] The first seating surface 431a may be formed in a shape corresponding to the shape of the seating 431. In the illustrated embodiment, the first seating surface 431a is in the shape of a truncated cone in which the radial inner portion is more convex toward the front than the outer portion.

[0372] The module body 410 is placed on the first seating surface 431a. The second module body end 415 can be tightly coupled to the first seating surface 431a.

[0373] The neck portion 432 is continuous with the first seating surface 431a and extends from the radially inner side of the second module body end portion 415 coupled to the first seating surface 431a toward a direction opposite to the first seating surface 431a, ie, the front side in the illustrated embodiment.

[0374] The first seating surface 431 a and the second seating surface 431 b are arranged opposite to each other.

[0375] The second seating surface 431 b forms the other side of the base 431 . In the illustrated embodiment, the second seating surface 431 b forms the rear side of the base 431 .

[0376] The second base surface 431b may be formed to extend along the outer periphery of the base 431 and have a predetermined thickness along the radial direction. Figure 16 As shown, the second seating surface 431 b is formed to protrude from the first seating surface 431 a toward the rear side, and its protruding length may be shorter than the boss portion 433 .

[0377] The second seating surface 431b is coupled to the second purification cover 220. Specifically, when the second vortex forming member 430 is coupled to the second purification cover 220, the second seating surface 431b surrounds the second coupling opening 222 from the radially outer side and is coupled to the front surface of the second plate 221.

[0378] Therefore, the second seating surface 431 b may be defined as a portion of the second vortex flow forming member 430 supported by the second purification cover 220 .

[0379] A boss portion 433 is formed radially inside the second seating surface 431 b. The second seating surface 431 b is formed to be spaced apart from the boss portion 433 along the radial direction and surround the boss portion 433.

[0380] Neck 432 is a portion that reshapes the flow of fluid entering the module body hollow space 413 into a vortex. Neck 432 is separated from the module body inner periphery 412, allowing the fluid to flow in a vortex in the space formed between them. In other words, neck 432 is contained within the hollow space formed within the vortex-shaped flow pattern formed by the fluid.

[0381] The neck portion 432 is continuous with the base portion 431. The neck portion 432 is formed to extend from the first base surface 431a toward the first module body end portion 414, that is, toward the front side in the illustrated embodiment.

[0382] The neck portion 432 is housed within the module body hollow space 413. Specifically, one end of the neck portion 432, in the illustrated embodiment, is coupled to the base 431. Furthermore, the other end of the neck portion 432, in the illustrated embodiment, is housed within the module body hollow space 413. The front end is spaced from the module body inner periphery 412 and remains suspended.

[0383] The neck 432 can be any shape that can form the flow of the fluid into a vortex form together with the module body 410. In the illustrated embodiment, the neck 432 has a circular cross-section and is in the shape of a truncated cone with a diameter decreasing in the direction opposite to the base 431, i.e., the front side.

[0384] A vortex cavity 434 extending through the base 431 is formed inside the neck 432 , so that the separated fluid, including foreign matter, can flow into the second purification main space 322 .

[0385] The neck portion 432 is disposed adjacent to the dust discharge portion 416 . In the illustrated embodiment, the neck portion 432 may be located above the dust discharge portion 416 , and foreign matter separated from the fluid may be discharged into the first purification main space 312 through the dust discharge portion 416 .

[0386] In the illustrated embodiment, the neck 432 includes an outer neck periphery 432a and an inner neck periphery 332b.

[0387] The neck periphery 432a forms the periphery of the neck 432. The neck periphery 432a can be defined as the outer surface of the neck 432. As described above, the neck 432 is a truncated cone with the vortex hollow 434 passing through it, so the neck periphery 432a can be called the side surface of the neck 432.

[0388] The neck outer periphery 432a is separated from the module body inner periphery 412 to form a space. Fluid flowing in from the outside can flow in the space. As described above, the fluid flows in a vortex shape when passing through the first vortex forming member 420.

[0389] The fluid formed at this time collides with the second purification cover 220 when passing through the space formed between the neck outer periphery 432 a and the module body inner periphery 412 , and then moves back toward the first vortex forming member 420 .

[0390] The neck inner periphery 332b forms the inner periphery of the neck 432. The neck inner periphery 332b can be defined as the inner surface of the neck 432. The neck inner periphery 332b is formed opposite to the neck outer periphery 432a. The neck inner periphery 332b partially surrounds the vortex hollow 434.

[0391] The neck inner circumference 332b may be formed so that the diameter of its cross section changes along the extending direction of the neck 432. In the illustrated embodiment, the cross-sectional diameter of the neck inner circumference 332b is formed so as to increase from the front side toward the rear side, that is, toward the base 431.

[0392] The neck inner circumference 332b partially surrounds the vortex hollow 434 formed therein. At this time, as described above, the diameter of the cross section of the neck inner circumference 332b changes along the extension direction of the neck 432, so it can be understood that the diameter of the cross section of the vortex hollow 434 also changes along its extension direction.

[0393] The neck inner periphery 332b surrounds the fluid flowing in the vortex hollow 434 from the radial direction. The fluid flowing in the vortex hollow 434 flows in a vortex form through the neck inner periphery 332b and does not flow out randomly in the radial direction.

[0394] The boss portion 433 is a portion for coupling the second vortex flow forming member 430 to the second purification cover 220 , and is inserted into and coupled to the second coupling opening 222 formed in the second purification cover 220 .

[0395] In one embodiment, the boss portion 433 can be sealed and inserted into the second coupling opening 222. In this embodiment, the fluid flowing into the purification module 400 can flow into the second purification main body space 322 only after passing through the vortex cavity 434 and the second coupling opening 222.

[0396] The boss portion 433 is continuous with the base 431. Figure 16 In the illustrated embodiment, the boss portion 433 is formed to protrude from the radial inner side of the second seating surface 332 b toward a direction opposite to the neck portion 432 , ie, toward the rear side.

[0397] The boss portion 433 may extend along the outer circumference of the base 431. Here, the boss portion 433 extends circumferentially radially inwardly of the second base surface 431b. Therefore, the boss portion 433 is formed to have an annular cross-section with a diameter smaller than that of the second base surface 431b.

[0398] The boss portion 433 extends toward the second purge cover 220, that is, toward the rear side in the illustrated embodiment, by a predetermined length. The boss portion 433 may be formed to extend longer than the second seating surface 431b.

[0399] Therefore, the second vortex forming member 430 and the second purification cover 220 may be configured such that the boss portion 433 is inserted and coupled to the second coupling opening 222 and the second seating surface 431 b contacts the front surface of the second plate 221 .

[0400] A vortex cavity 434 is partially formed inside the boss portion 433 .

[0401] The vortex cavity 434 serves as a channel for the fluid flowing in a vortex form again through the second vortex forming member 430 to flow out of the second purification main body space 322. The vortex cavity 434 extends along the extension direction of the second vortex forming member 430, that is, the front-to-back direction in the illustrated embodiment.

[0402] The vortex cavity 434 is open at each end in its extension direction, i.e., the front end and the rear end in the illustrated embodiment. The front end of the vortex cavity 434 communicates with the module body cavity 413. The rear end of the vortex cavity 434 communicates with the second coupling opening 222.

[0403] That is, the vortex hollow 434 is formed through the inside of the second vortex forming member 430. The fluid flowing in through the front end of the vortex hollow 434 can flow into the second purification main body space 322 via the rear end of the vortex hollow 434.

[0404] The vortex hollows 434 may be partially formed inside various components constituting the second vortex forming member 430. In the illustrated embodiment, the vortex hollows 434 are formed through the base 431, the neck 432, and the boss 433.

[0405] The vortex hollow 434 can be formed so that the cross-sectional area changes along its extending direction. Figure 12 As shown, the vortex hollow 434 is formed so that the cross-sectional area increases in the direction toward the second purification cover 220 .

[0406] The vortex cavity 434 may be any shape that allows fluid to flow in a vortex pattern and flow out to the second purification main space 322. In the illustrated embodiment, the vortex cavity 434 is formed in a circular truncated cone shape with a cross-sectional area increasing toward the rear.

[0407] Reference Figure 17 and Figure 18 The electric power device 1 according to the embodiment of the present invention includes a discharge unit 30 .

[0408] The discharge unit 30 discharges foreign matter and the like separated from the external fluid when passing through the purification unit 20 to the outside of the electric power equipment 1 . The discharge unit 30 communicates with the purification unit 20 via the flow path 40 .

[0409] The exhaust unit 30 may be any type capable of providing a conveying force for the foreign matter captured in the purification unit 20 to flow outside the power equipment 1. In the illustrated embodiment, the exhaust unit 30 includes an exhaust fan assembly 600 for providing a conveying force for the captured foreign matter.

[0410] The discharge unit 30 is coupled to the housing 10. Specifically, the discharge unit 30 is housed within the housing space 14 formed within the housing 10. In this case, the discharge unit 30 can be positioned toward the other side of the housing space 14 in the height direction, i.e., the lower side in the illustrated embodiment. In other words, the discharge unit 30 is positioned further downward than the purification unit 20.

[0411] Thus, as described above, foreign matter and the like captured in the purification unit 20 can smoothly flow toward the discharge unit 30 .

[0412] The discharge unit 30 is disposed adjacent to the purification unit 20. Foreign matter and the like separated by the purification unit 20 can be discharged to the discharge unit 30. The discharge unit 30 and the purification unit 20 are in communication.

[0413] The discharge unit 30 is connected to the flow path unit 40 . The space formed inside the discharge unit 30 can communicate with the flow path unit 40 , so that foreign matter and the like captured in the purification unit 20 can flow into the space formed inside the discharge unit 30 .

[0414] Below, refer to Figure 17 and Figure 18 , the exhaust unit 30 will be described in detail. In the illustrated embodiment, the exhaust unit 30 includes a exhaust frame 500 and an exhaust fan assembly 600.

[0415] The discharge frame 500 forms a main body of the discharge portion 30. A space is formed inside the discharge frame 500 to accommodate the discharge fan assembly 600.

[0416] The discharge frame 500 is housed in the housing space 14 and is partially surrounded by the first outer surface 11 and the second outer surface 12. In the illustrated embodiment, the front side of the discharge frame 500 is surrounded by the first outer surface 11, and the left and right sides of the discharge frame 500 are respectively surrounded by the second outer surface 12.

[0417] The exhaust frame 500 is combined with the exhaust fan assembly 600. The exhaust frame 500 accommodates the exhaust fan assembly 600 therein.

[0418] The exhaust frame 500 communicates with the outside. Specifically, the exhaust frame 500 communicates with the outside through a support passage 542 formed in the support frame 540. Foreign matter and the like that reaches the exhaust portion 30 can be discharged to the outside of the power equipment 1 through the exhaust fan assembly 600, the support space 541, and the support passage 542.

[0419] In the illustrated embodiment, the discharge frame 500 includes a first discharge frame 510 , a second discharge frame 520 , a third discharge frame 530 , and a support frame 540 .

[0420] The first exhaust frame 510 forms a portion of the outer shape of the exhaust frame 500 . The first exhaust frame 510 forms one side in the height direction of the exhaust frame 500 , ie, the upper side in the illustrated embodiment. The first exhaust frame 510 is located above the exhaust fan assembly 600 .

[0421] The first exhaust frame 510 may be in contact with the third purification frame 140. That is, in the embodiment, the first exhaust frame 510 is configured to support the purification frame 100.

[0422] The first discharge frame 510 can be of any shape, forming the upper portion of the discharge frame 500 and capable of supporting the purification frame 100. In the illustrated embodiment, the first discharge frame 510 has a fork shape, with an opening formed at the rear and continuous front, left, and right sides. The shape of the first discharge frame 510 can be modified to correspond to the shape of the third purification frame 140.

[0423] Each end of the first exhaust frame 510 in the extending direction, i.e., the left end and the right end in the illustrated embodiment, is respectively arranged adjacent to the second exhaust frame 520. In addition, the first exhaust frame 510 is arranged to face the third exhaust frame 530 and the support frame 540 with the exhaust fan assembly 600 interposed therebetween.

[0424] The second exhaust frame 520 forms another portion of the outer shape of the exhaust frame 500. There are a plurality of second exhaust frames 520, which are coupled to each widthwise side of the first exhaust frame 510, namely, the left and right sides in the illustrated embodiment. The second exhaust frames 520 surround the space housing the exhaust fan assembly 600 from these sides. A pair of second exhaust frames 520 are arranged facing each other, sandwiching the exhaust fan assembly 600 between them.

[0425] The second discharge frame 520 is coupled to the first discharge frame 510 and the third discharge frame 530. One side of the second discharge frame 520 in the height direction, i.e., the upper side in the illustrated embodiment, is coupled to the first discharge frame 510. The other side of the second discharge frame 520 in the height direction, i.e., the lower side in the illustrated embodiment, is coupled to the third discharge frame 530.

[0426] The second exhaust frame 520 can be any shape that is combined with the first exhaust frame 510 and the second exhaust frame 520 and can partially surround the exhaust fan assembly 600. In the illustrated embodiment, the second exhaust frame 520 is a quadrilateral plate having a width in the front-to-back direction, a height in the up-down direction, and a thickness in the left-to-right direction.

[0427] The third exhaust frame 530 forms a component of the exhaust frame 500. The third exhaust frame 530 is coupled to the exhaust fan assembly 600 and supports the exhaust fan assembly 600.

[0428] The third discharge frame 530 may be formed in accordance with the shape of the support frame 540 or the support space 541. In the illustrated embodiment, the third discharge frame 530 is a quadrilateral plate having a length in the left-right direction longer than in the front-back direction and a thickness in the top-bottom direction.

[0429] The third exhaust frame 530 is disposed facing the first exhaust frame 510. In the illustrated embodiment, the third exhaust frame 530 is disposed facing the first exhaust frame 510 across the exhaust fan assembly 600. The third exhaust frame 530 is disposed spaced apart from the first exhaust frame 510 along its thickness direction, i.e., in the vertical direction.

[0430] The third discharge frame 530 is coupled to the second discharge frame 520. In the illustrated embodiment, each end portion of the third discharge frame 530 in the longitudinal direction, ie, the left end portion and the right end portion, is coupled to the second discharge frame 520, respectively.

[0431] The third discharge frame 530 is coupled to the support frame 540. The third discharge frame 530 covers the support space 541 formed in the support frame 540 from one side in its height direction, i.e., the upper side in the illustrated embodiment, and is coupled to the support frame 540. This seals the support space 541 from one side, i.e., the upper side, so that dust flowing into the support space 541 can only be discharged from the support space 541 through the support connection portion 542.

[0432] In the illustrated embodiment, the third discharge frame 530 includes a discharge opening portion 531 .

The exhaust opening 531 connects the exhaust fan assembly 600 coupled to the third exhaust frame 530 with the support space 541.

[0434] The discharge opening 531 can be of any shape that allows the exhaust fan assembly 600 to communicate with the support space 541. In the illustrated embodiment, the discharge opening 531 is formed as a quadrilateral plate-shaped space having a quadrilateral cross-section and a thickness in the vertical direction. The position and shape of the discharge opening 531 can be changed depending on the shape of the second discharge cover 612 provided in the exhaust fan assembly 600.

[0441] One side of the support space 541 in the height direction, i.e., the upper side in the illustrated embodiment, is open, thereby communicating with the exhaust fan assembly 600 through the exhaust opening 531. The other side of the support space 541 in the height direction, i.e., the lower side in the illustrated embodiment, is open, so that any foreign matter that enters the support space 541 can be captured on the ground, etc., where the power equipment 1 is placed.

[0442] Alternatively, the other side of the support space 541 may be closed or provided with an additional drawer or the like, so that trapped foreign matter or the like can be easily removed.

[0443] Each end portion of the support space 541 in the longitudinal direction, ie, the front side and the rear side end portion in the illustrated embodiment, is communicated with the outside through the support communication portion 542 .

[0444] The support passage 542 connects the support space 541 to the outside. The support passage 542 extends through one of the surfaces of the support frame 540 that surround the support space 541 from the outside, namely, the surface that surrounds the support space 541 from the front in the illustrated embodiment.

[0507] 3. Description of the Flow Process of the Fluid Flowing into the Power Equipment 1 in the Embodiment of the Present Invention

[0508] The power device 1 of the embodiment of the present invention can form the flow of the external fluid into a vortex shape through the above-mentioned structure. The fluid flowing into the power device 1 can flow in a vortex shape, and mixed foreign matter can be centrifugally separated and removed.

[0509] Furthermore, the separated foreign matter and the like are discharged to the outside and do not stay or accumulate inside the electric power device 1. Thus, the components of the electric power device 1 can be cooled efficiently, and damage to the components caused by the separated foreign matter and the like can be prevented.

[0510] Below, refer to Figures 21 to 24 , a process of forming a fluid flow inside the electric power equipment 1 and separating foreign matter mixed in the fluid based on the flow and discharging the separated foreign matter to the outside according to an embodiment of the present invention is described in detail.

[0511] The term "first flow F1" used in the following description refers to the flow of fluid formed in the module body hollow space 413 toward the second purge cover 220, that is, toward the rear side in the illustrated embodiment. The first flow F1 is formed in the module body hollow space 413 and outside the second vortex forming member 430.

[0512] The term "second flow F2" used in the following description refers to the flow of fluid formed in the module body hollow space 413 and directed in the direction opposite to the second purge cover 220, that is, the forward direction in the illustrated embodiment. The second flow F2 is also formed in the module body hollow space 413 and outside the second vortex forming member 430.

[0513] At this time, it can be understood that the first flow F1 corresponds to the relatively upstream side in the flow of the fluid, and the second flow F2 corresponds to the relatively downstream side in the flow of the fluid.

[0514] In addition, the term "dust flow FD" used in the following description refers to the flow of foreign matter and the like that is originally mixed in a fluid and then centrifugally separated by the flow of the fluid and separated from the fluid.

[0515] Reference Figure 21 and Figure 22 , which shows the flow process of the fluid formed inside the power equipment 1 according to an embodiment of the present invention. The flow process of the fluid shown in the figure can be performed by the operation of the suction fan 340 provided in the purification body 300.

[0516] First, the external fluid flows through the cover space 14 and the front side end of the purification module 400 into the module body hollow space 413. In this case, the purification module 400 has multiple modules, which are arranged at different positions. The external fluid flows into the multiple module body hollow spaces 413 formed inside the multiple purification modules 400.

[0517] At this time, the external fluid flows into the module body hollow space 413 after passing through the first vortex-forming member 420, which is located adjacent to the front end of the purification module 400. Therefore, the first flow F1 is formed as a vortex-shaped vortex and flows through the module body hollow space 413. It can be understood that the direction of the first flow F1 is from the first vortex-forming member 420 toward the second vortex-forming member 430.

[0518] Since the first flow F1 is formed as a vortex, a centrifugal force is generated in the fluid in a radially outward direction, that is, in a direction toward the module body inner periphery 412. As a result, foreign matter and the like move radially outward.

[0519] After reaching the second vortex-forming member 430 and colliding with the second purge cover 220, the fluid flows back toward the first vortex-forming member 420. At this point, due to the shape of the second vortex-forming member 430, the second flow F2 also forms a vortex. This generates centrifugal force in the fluid toward the module body inner circumference 412, causing foreign matter and the like to move radially outward.

[0520] A dust discharge portion 416 is formed through the module body outer periphery 411 and the module body inner periphery 412, connecting the module body hollow space 413 with the first purification main body space 312. In one embodiment, the dust discharge portion 416 can be formed on the lower side of the module body 410. Thus, foreign matter separated from the fluid passes through the dust discharge portion 416 and is discharged into the first purification main body space 312.

[0521] That is, the dust flow FD extends from the radial outside of the module body hollow 413 to the first purification main body space 312 via the dust discharge portion 416 .

[0522] On the other hand, the second flow F2 extends along the neck portion 432 of the second vortex-forming member 430 toward the first vortex-forming member 420, that is, toward the front side in the illustrated embodiment. The second flow F2 extending to the front end of the neck portion 432 flows into the open vortex cavity 434. The fluid flowing into the vortex cavity 434 flows into the second purification main body space 322 connected to the vortex cavity 434.

[0523] Then, the fluid flows into the internal space of the electric power device 1 via the suction fan 340 , and cools the components of the electric power device 1 .

[0524] Reference Figure 23 and Figure 24 , which shows the flow process of foreign matter and the like formed inside the power equipment 1 according to the embodiment of the present invention. The flow process of foreign matter and the like shown can be performed by the operation of the exhaust fan member 630 provided in the exhaust fan assembly 600.

[0525] First, the separated foreign matter and other particles are captured in the second space 312b of the first main purification space 312. When the exhaust fan assembly 630 is activated, suction is applied to the second space 312b along the flow path 40 connected to and in communication with the exhaust fan assembly 600. In other words, the suction acts as a conveying force that propels the foreign matter and other particles contained in the second space 312b toward the exhaust section 30.

[0526] Foreign matter trapped in the second space 312b flows into the communication flow paths 710 and 720 through the communication ends 711, 712, 721, and 722. The foreign matter flowing into the communication flow paths 710 and 720 flows out to the connection flow path 830 through the discharge flow paths 810 and 820.

[0527] Foreign matter and the like that flows into the connecting flow path portion 830 passes through the discharge communication hole 621 and flows out to the support space 541 via the internal space of the discharge cover 610. The support space 541 is connected to the outside through the support communication portion 542, so that the foreign matter and the like that flows into the support flow path portion 830 can flow out to the outside through the support communication portion 542.

[0528] Therefore, foreign matter and the like separated and captured from the fluid by the purification unit 20 can be discharged to the outside without being retained inside the purification unit 20 .

[0529] Although the embodiments of the present invention have been described, the concept of the present invention is not limited to the embodiments given in this specification. Those skilled in the art who understand the concept of the present invention can easily propose other embodiments within the scope of the same concept by adding, changing, deleting, or appending constituent elements, which also falls within the scope of the concept of the present invention.
