Description

Technical Field

[0001] The present invention relates to blowers, and more specifically, to a blower in which the housing disposed on the upper side of a base rotates based on the base. Background Technology

[0002] A blower is a device that supplies air to a localized area in a concentrated manner.

[0003] In order to adjust the direction of the air discharged from the blower, the blower body needs to rotate, and the blower can be equipped with bearings to support the rotation of the body.

[0004] In the blower, the structure on the upper side of the base can rotate with respect to the base located on the ground. At this time, the motor that rotates the blower is mounted on the base, which allows the upper structure to rotate.

[0005] Korean Patent No. 10-1370267 discloses a structure in which a motor is mounted on a base and a structure located on the upper side of the base rotates. In this structure, when the printed circuit board or other components that regulate the operation of the motor mounted on the base are separately mounted from the base, there is a problem that the internal structure of the base becomes larger.

[0006] In this structure, if the printed circuit board used to operate the fan is located on the upper side of the base, there is a problem that a printed circuit board for operating the motor needs to be placed inside the base. Furthermore, if the printed circuit board is located in the upper structure of the base, there may be issues with kinking of wires connected to the motor.

[0007] To ensure stable rotation of the blower, if an electrical control device is installed in the structure above the base, the wiring arrangement inside the base can be altered. However, this altered wiring arrangement within the base may lead to problems such as wire contact or kinking. Such kinking or contact can cause blower malfunctions. Summary of the Invention

[0008] The problem to be solved by the present invention is to provide a blower that uses an electronic device disposed inside a rotating blower to stably supply power.

[0009] Another objective of the present invention is to provide a blower that prevents wire kinking or interference between wires due to the rotation of the blower.

[0010] Another objective of this invention is to provide a blower capable of integrated management of electrical components.

[0011] The subject matter of this invention is not limited to the subject matter mentioned above, and those skilled in the art can clearly understand other subject matters not mentioned from the following description.

[0012] To achieve the above-mentioned objectives, the blower of the present invention includes: a base; a housing disposed on the upper side of the base, having an inlet and an outlet; and a rotating plate disposed on the lower side of the housing, rotatably disposed on the base, so that the rotating plate and the housing can rotate on the upper side of the base.

[0013] Additionally, the blower includes: an electrical wire, a portion of which protrudes to the outside of the base and the remainder extends through the base to the upper side of the rotating plate; and an electrical wire retainer, fixedly disposed on the rotating plate, fixing one side of the electrical wire extending from the inside of the base to the upper side of the rotating plate, thereby stably maintaining the arrangement of the electrical wire extending to the upper side of the base.

[0014] The base includes: a wire fixing protrusion for fixing the other side of the wire extending from the outside into the inner space of the base; and a wire guide rib for fixing a portion of the wire whose arrangement changes in the inner space of the base as the rotating plate moves, thereby limiting the range of movement of the wire whose arrangement changes in the inner space of the base.

[0015] The base includes a lower body forming an inner space and an upper body disposed on the upper side of the inner space. A wire guide rib protruding toward the lower body is disposed on the lower surface of the upper body, thereby fixing a portion of the wire arrangement.

[0016] The wire guide rib includes: an outer guide rib that restricts the wire from moving radially outward; and an inner guide rib that is spaced apart from the outer guide rib and fixes a portion of the wire arrangement.

[0017] The outer guide rib forms a cutout area for arranging the wire in the area where the wire fixing protrusion is configured, so that the wire extending from the outside to the inside of the base can be arranged on the inside of the outer guide rib.

[0018] The inner guide rib includes: a first inner guide rib spaced apart from the outer guide rib by a predetermined interval; and a second inner guide rib whose spacing from the outer guide rib can be increased, thereby providing a structure that fixes the arrangement of wires extending from the outside to the inside of the base and can change the arrangement of wires extending to the wire holder.

[0019] The second inner guide rib is further spaced from the wire fixing protrusion than the first inner guide rib, thereby securing the arrangement of the base extending from the outside into the inner space of the base.

[0020] The first inner guide rib and the second inner guide rib can be arranged separately in the circumferential direction.

[0021] It also includes additional ribs disposed between the wire fixing protrusion and the rotation center of the upper plate, thereby preventing contact between wires arranged in varying ways in the inner space of the base and wires extending from the outside to the inside of the base.

[0022] The additional rib extends from one end of the outer guide rib and can divide the wires extending from the outside into the inner space of the base and the wires connected to the wire holder.

[0023] The wire includes: a first wire fixed to the outer guide rib and the inner guide rib; and a second wire extending from the first wire to the wire holder; the second wire is longer than the first wire, which can expand the rotation range of the blower.

[0024] A wire hole is formed on one side of the lower body for the wire to pass through. The wire is fixedly protruding at the position formed by the wire hole and is disposed on the upper body, which can fix one side of the wire extending from the outside to the inside of the base.

[0025] The wire retainer includes: an upper panel fixed to the rotating plate and having a wire through hole for the wire to pass through; a lower panel spaced downward from the upper panel; and a connecting wall connecting the upper panel and the lower panel. A wire fixing member is disposed on the lower panel on one side for fixing the wire. When the rotating plate rotates, the wire fixing member disposed in the inner space of the base also rotates, thus stably maintaining the arrangement of the wire disposed on the upper side of the rotating plate.

[0026] A fastening rib that engages with the rotating plate is provided on the upper side of the top plate. In the wire retainer, with the fastening part installed on the fastening rib, the top plate is engaged with the fastening part by a fastening member, thereby allowing the rotating plate and the wire retainer to rotate as a whole.

[0027] A shaft bearing supporting the rotation of the rotating plate is disposed between the rotating plate and the bearing, and the wire retainer is fastened to the rotating plate inside the shaft bearing, thereby restricting the movement of the wire extending upward toward the base.

[0028] The blower of the present invention includes: a base; a housing disposed on the upper side of the base, having an inlet and an outlet; a fan disposed inside the housing, forming an airflow from the inlet to the outlet; a rotating plate disposed on the lower side of the housing and rotatably disposed on the base; a drive unit mounted on the rotating plate, contacting the base to rotate the rotating plate relative to the base; a control device disposed on the upper side of the rotating plate and electrically connected to the drive unit or the fan; and a wire, a portion of which protrudes outside the base, and the remainder extends through the base to the fan disposed on the housing. The control device on the upper side of the rotating plate; and the wire retainer, including an upper body and a lower body, the upper body being fixedly disposed on the rotating plate, the lower body being disposed in the inner space of the base, fixing one side of the wire extending toward the upper side of the rotating plate; the base including: a wire fixing protrusion, fixing the other side of the wire extending from the outside toward the inner space of the base; an outer guide rib, restricting the wire from moving radially outward; and an inner guide rib, spaced apart from the outer guide rib, fixing a portion of the wire arrangement, thereby restricting changes in the arrangement of the wire disposed inside the base.

[0029] The wire holder rotates together with the rotating plate, and a wire fixing member is arranged on the lower surface of the lower body to fix one side of the wire. The arrangement of the wire can be varied within the internal space of the base.

[0030] As the rotating plate rotates, the interval between the wire fixing member and the wire fixing protrusion changes.

[0031] The wire retainer includes: an upper panel fixed to the rotating plate and having a wire through hole for the wire to pass through; a lower panel spaced downward from the upper panel; and a connecting wall having a hollow column shape and connecting the upper panel and the lower panel, wherein the wire extends upward through the internal space of the connecting wall.

[0032] Detailed descriptions of other embodiments are provided in the accompanying drawings.

[0033] The blower according to the present invention has one or more of the following effects.

[0034] First, the area where the wiring arrangement changes due to the rotation of the blower is located in the inner space of the base, and the area where the electronic devices located inside the blower are located is located on the upper side of the rotating plate of the base, thus having the advantage that the wiring can be stably connected to the electronic devices even when the blower rotates.

[0035] Secondly, by arranging wire guide ribs, which are part of the wires, in the space inside the base where the wire arrangement varies, wire kinking or contact between wires is prevented, thus preventing blower malfunctions. Additionally, it has the advantage of preventing wire twisting caused by rotation by having the wires pass through the center of the wire holder.

[0036] Third, the electronic devices are centrally located on the upper side of the rotating plate, thus also having the advantage of enabling integrated management of electrical components connected by wires.

[0037] The effects of the present invention are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned from the following description. Attached Figure Description

[0073] The advantages and features of the present invention, as well as methods of implementing them, will become clear with reference to the following accompanying drawings and detailed description of embodiments. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided only to complete the disclosure of the invention and to fully inform those skilled in the art to which this invention pertains. The invention is defined only by the scope of the claims. Throughout this specification, the same reference numerals refer to the same constituent elements.

[0074] The present invention will now be described with reference to the accompanying drawings of a blower used to illustrate embodiments thereof.

[0075] Reference Figures 1 to 5 First, let me explain the overall structure of the blower 1.

[0076] The blower 1 of this invention includes a housing 100 with a defined shape. The housing 100 includes: a lower housing 210 with a filter 220 disposed thereon; and a tower housing 140 that discharges air via the Coanda effect.

[0077] The tower shell 140 includes a first tower 110 and a second tower 120, which are configured as two columnar structures separated from each other. Figure 1 Based on this, the first tower 110 can be configured on the right side, and the second tower 120 can be configured on the left side.

[0078] The first tower 110 and the second tower 120 are separated from each other, and an air supply space 105 is formed between the first tower 110 and the second tower 120.

[0079] The front, rear and top openings of the air supply space 105, and the left and right intervals of the upper and lower ends of the air supply space 105 can be formed to be the same.

[0080] The tower shell 140, which includes the first tower 110, the second tower 120, and the air supply space 105, can have a truncated conical shape.

[0081] Air is discharged into the air supply space 105 through outlets 117 and 127 formed in the first tower 110 and the second tower 120, respectively. When it is necessary to distinguish the outlets, the outlet formed in the first tower 110 is referred to as the first outlet 117, and the outlet formed in the second tower 120 is referred to as the second outlet 127.

[0082] The first outlet 117 and the second outlet 127 can extend vertically in the air supply space 105, and the direction that crosses the air supply space 105 is defined as the air discharge direction.

[0083] Since the first tower 110 and the second tower 120 are arranged in the left-right direction, the air discharge direction can be formed in the front-back direction.

[0084] That is, the air discharge direction that traverses the air supply space 105 can be defined as the first air discharge direction S1 formed in the horizontal direction.

[0085] Furthermore, as the Coanda breaker 400 (described later) moves, the air discharge direction through the air supply space 105 can also be formed in the vertical direction. In this case, the air discharge direction traversing the air supply space 105 can be defined as a second air discharge direction S2 formed in the vertical direction.

[0086] The air flowing in the first air discharge direction S1 is called the horizontal airflow, and the air flowing in the second air discharge direction S2 is called the updraft.

[0087] Horizontal airflow does not mean that air flows only horizontally, but rather that a greater volume of air flows horizontally. Similarly, upward airflow does not mean that air flows only upward, but rather that a greater volume of air flows upward.

[0088] The upper and lower gaps of the air supply space 105 can be the same. However, the upper gap of the air supply space 105 can also be narrower or wider than the lower gap.

[0089] By maintaining a constant left and right width of the air supply space 105, the airflow in front of the air supply space 105 can be formed more evenly.

[0090] For example, if the width of the upper side and the width of the lower side are different, the flow velocity on the wider side may be lower, resulting in a velocity deviation based on the vertical direction. When this vertical airflow velocity deviation occurs, the supply of purified air can vary depending on the vertical position of the emitted air.

[0091] The air discharged from the first outlet 117 and the second outlet 127 can be combined in the air supply space 105 and then supplied to the user.

[0092] That is, the air discharged from the first outlet 117 and the air discharged from the second outlet 127 are combined in the air supply space 105 and then supplied to the user without flowing to the user separately.

[0093] The air supply space 105 can be used as a space for the exhaust air to converge and mix. In addition, by exhausting the air into the air supply space 105, the air behind the air supply space 105 can also flow into the air supply space 105.

[0094] The air discharged from the first outlet 117 and the second outlet 127 converge in the air supply space 105, thereby improving the straightness of the discharged air. In addition, by converging the air discharged from the first outlet 117 and the second outlet 127 in the air supply space 105, the air around the first tower 110 and the second tower 120 can also be guided to flow in the direction of air discharge.

[0095] by Figure 2 Based on this, the first air discharge direction S1 is formed from the rear to the front, and the second air discharge direction S2 is formed from the lower side to the upper side.

[0096] To form the second air discharge direction S2, the upper end 111 of the first tower 110 and the upper end 121 of the second tower 120 are spaced apart from each other in the left-right direction. That is, the air discharged along the second air discharge direction S2 will not interfere with the housing 100 of the blower 1.

[0097] In order to form the first air discharge direction S1, the front end 112 of the first tower 110 and the front end 122 of the second tower 120 are separated from each other in the left-right direction, and the rear end 113 of the first tower 110 and the rear end 123 of the second tower 120 are also separated from each other in the left-right direction.

[0098] The surfaces of the first tower 110 and the second tower 120 that face the air supply space 105 are defined as the inner surfaces, and the surfaces that do not face the air supply space 105 are defined as the outer surfaces.

[0099] The outer sidewall 114 of the first tower 110 and the outer sidewall 124 of the second tower 120 are configured to face each other, and the inner sidewall 115 of the first tower 110 and the inner sidewall 125 of the second tower 120 are formed to face each other.

[0100] When it is necessary to distinguish between the inner sidewalls 115 and 125, the inner side of the first tower 110 is defined as the first inner sidewall 115, and the inner side of the second tower 120 is defined as the second inner sidewall 125.

[0101] Similarly, when it is necessary to distinguish between the outer sidewalls 114 and 124, the outer side of the first tower 110 is defined as the first outer sidewall 114, and the outer side of the second tower 120 is defined as the second outer sidewall 124.

[0102] The first tower 110 and the second tower 120 can be formed in a streamlined shape relative to the direction of air flow.

[0103] Specifically, the first inner wall 115 and the first outer wall 114 may be streamlined relative to the front-back direction, and the second inner wall 125 and the second outer wall 124 may be streamlined relative to the front-back direction.

[0104] The first outlet 117 is formed on the first inner wall 115, and the second outlet 127 is formed on the second inner wall 125.

[0105] The shortest distance between the first inner wall 115 and the second inner wall 125 is defined as B0. The discharge outlets 117 and 127 may be located on the rear side than the shortest distance B0.

[0106] The distance between the front end 112 of the first tower 110 and the front end 122 of the second tower 120 is defined as the first separation distance B1, and the distance between the rear end 113 of the first tower 110 and the rear end 123 of the second tower 120 is defined as the second separation distance B2.

[0107] The first separation distance B1 and the second separation distance B2 can be the same. However, one of the separation lengths of the first separation distance B1 and the second separation distance B2 can also be longer.

[0108] The first discharge port 117 and the second discharge port 127 can be formed between the position formed by the shortest distance B0 and the position formed by the second distance B2.

[0109] The first outlet 117 and the second outlet 127 are preferably formed at positions closer to the rear end 113 of the first tower 110 and the rear end 123 of the second tower 120 than the position formed by the shortest distance B0.

[0110] The closer the outlets 117 and 127 are to the rear end 113 and 123, the easier it is to control the airflow caused by the Coanda effect, which will be described later.

[0111] The inner wall 115 of the first tower 110 and the inner wall 125 of the second tower 120 directly provide the Coanda effect, while the outer wall 114 of the first tower 110 and the outer wall 124 of the second tower 120 indirectly provide the Coanda effect.

[0112] The inner walls 115 and 125 directly guide the air discharged from the outlets 117 and 127 to the front ends 112 and 122. That is, the inner walls 115 and 125 guide the air discharged from the outlets 117 and 127 to form a horizontal airflow.

[0113] Due to the Coanda effect generated in the air supply space 105, horizontal airflow is formed, thus indirect airflow is also generated on the outer walls 114 and 124.

[0114] The outer walls 114 and 124 induce the Coanda effect on the aforementioned indirect airflow and guide the aforementioned indirect airflow to the front ends 112 and 122.

[0115] The Coanda breaker 400, described later, can switch the horizontal airflow through the air supply space 105 into an upward airflow, which can flow towards the open upper side of the air supply space 105. The upward airflow prevents the exhaust air from flowing directly towards the user and can activate indoor air convection. In addition, by adjusting the width of the exhaust air that converges in the air supply space 105, the flow rate of the exhaust air blown from the blower 1 can be adjusted.

[0116] A first panel slit 119 for the Coanda destroyer 400 to move is formed extending vertically in the first tower 110, and a second panel slit 129 for the Coanda destroyer 400 to move is formed extending vertically in the second tower 120. Panel slits 119 and 129 can be formed on the inner sidewalls 115 and 125, respectively, and can open into the internal space of towers 110 and 120. Panel slits 119 and 129 are formed at positions closer to the front end 112 of the first tower 110 and the front end 122 of the second tower 120 than the position formed by the shortest distance B0.

[0117] By making the vertical length of the first discharge port 117 and the second discharge port 127 longer than the horizontal width B0, B1, B2 of the air supply space 105, the air discharged from the first discharge port 117 and the air discharged from the second discharge port 127 can be guided to converge in the air supply space 105.

[0118] The housing 100 of the blower 1 includes: a lower housing 210, in which a filter 220 is disposed; and a tower housing 140, disposed on the upper side of the lower housing 210 and supported by the lower housing 210. The lower housing 210 can form the appearance of an air supply unit 200, which includes a series of devices for drawing in outside air and supplying it upward.

[0119] The tower shell 140 forms the appearance of the first tower 110 and the second tower 120.

[0120] The tower shell 140 may include a tower base 130 connecting the first tower 110 and the second tower 120, and the tower base 130 may be assembled to the lower shell 210. The tower base 130 may be integrally formed with the first tower 110 and the second tower 120.

[0121] Unlike this embodiment, the first tower 110 and the second tower 120 can be directly assembled to the lower shell 210 without the tower base 130, or they can be made into one piece with the lower shell 210.

[0122] The lower housing 210 forms the lower part of the blower 1, and the tower housing 140 forms the upper part of the blower 1. A filter 220 can be disposed inside the lower housing 210, which filters out foreign matter contained in the air flowing in through the air inlet 211 formed along the outer peripheral surface of the lower housing 210.

[0123] The blower 1 draws in ambient air through the air inlet 211 formed in the lower housing 210, filters the air drawn in by the intake filter 220, and discharges the filtered air from the tower housing 140. The tower housing 140 can discharge air at a position higher than the lower housing 210.

[0124] The blower 1 can have a cylindrical shape with its diameter gradually decreasing towards the top, and the blower 1 as a whole can have a conical or truncated cone shape. With the cross-section narrowing towards the top, it has the advantage of a lower center of gravity and reduced risk of tipping over due to external impacts. However, unlike this embodiment, it can also have a shape where the cross-section does not narrow towards the top.

[0125] For ease of assembly, the lower housing 210 and the tower housing 140 can be manufactured as separate components and then assembled. However, unlike this embodiment, the lower housing 210 and the tower housing 140 can also be formed as a single unit. For example, the base housing and the tower housing can also be manufactured as a single unit, forming a front and rear housing, and then assembled.

[0126] The lower shell 210 can be formed in a shape where the diameter gradually decreases as it approaches the upper end, and the tower shell 140 can also be formed in a shape where the diameter gradually decreases as it approaches the upper end.

[0127] The outer surfaces of the lower shell 210 and the tower shell 140 can form a continuous surface. The lower end of the tower base 130 and the upper end of the lower shell 210 can be in close contact, and the outer surfaces of the tower base 130 and the lower shell 210 can form a continuous surface. For this purpose, the diameter of the lower end of the tower base 130 can be equal to or slightly smaller than the diameter of the upper end of the lower shell 210.

[0128] The lower housing 210 and the tower housing 140 are rotated in the circumferential direction by a drive unit 700 disposed on the lower side of the lower housing 210. The drive unit 700 can rotate the entire blower 1 body, including the housing 100, the air supply unit 200, and the towers 110 and 120. When the blower 1 is rotated by the drive unit 700, the direction of the horizontal airflow discharged from the blower 1 through the air supply space 105 can be switched.

[0129] The tower base 130 distributes filtered air supplied from the interior of the lower housing 210, and the distributed air is provided to the first tower 110 and the second tower 120.

[0130] The tower base 130 connects the first tower 110 and the second tower 120, and the air supply space 105 is formed on the upper side of the tower base 130.

[0131] An outlet 117 and 127 are formed on the upper side of the tower base 130, and rising airflow and horizontal airflow are formed on the upper side of the tower base 130.

[0132] To minimize friction with the air, the upper surface 131 of the tower base 130 can be formed as a curved surface. The upper surface 131 can be formed as a downwardly concave curved surface that can extend in the front-rear direction. One side 131a of the upper surface 131 can be connected to the first inner wall 115, and the other side 131b of the upper surface 131 can be connected to the second inner wall 125.

[0133] Reference Figure 5 When viewed from above, the first tower 110 and the second tower 120 are symmetrical about the center line L-L'. The first outlet 117 and the second outlet 127 are also symmetrical about the center line L-L'.

[0134] The centerline L-L' is a virtual line between the first tower 110 and the second tower 120. In this embodiment, it is formed along the front-back direction and passes through the upper side surface 131.

[0135] Unlike this embodiment, the first tower 110 and the second tower 120 can also be formed in an asymmetrical shape. However, with the center line L-L' as the reference, symmetrically arranging the first tower 110 and the second tower 120 can evenly distribute the flow within the air supply space 105, which is more advantageous in controlling horizontal and upward airflow.

[0136] The following is for reference Figures 6 to 8 This describes the internal structure of the blower 1.

[0137] The blower 1 includes: a filter 220 disposed inside the housing 100; and a fan assembly 300 disposed inside the housing 100, which directs air drawn in through the air inlet 211 to the outlets 117 and 127. The filter 220 and the fan assembly 300 may be disposed inside the lower housing 210.

[0138] The lower housing 210 may be formed in the shape of a truncated cone and open on the upper side. The air supply unit 200, which includes the filter 220 and the fan device 300, includes a lower housing 210 surrounding the filter 220 and the fan device 300, and a plurality of air inlets 211 communicating with the inner and outer sides of the lower housing 210 are formed along the circumferential direction of the lower housing 210.

[0139] The lower housing 210 can be formed into a truncated cone shape with openings on the upper and lower sides. The lower housing 210 can be manufactured separately into two parts, which can be assembled to form the aforementioned truncated cone shape. The two parts can be divided into a front housing (not shown) that separates towards the front of the blower 1 and a rear housing (not shown) that separates towards the rear. The filter 220 disposed inside the lower housing 210 can be brought out by separating one of the two parts.

[0140] The filter 220 can be formed as a cylinder with a hollow 221 extending in the vertical direction inside, and the outer surface of the filter 220 can face the air inlet 211.

[0141] Outside air from the blower 1 flows from the outside to the inside of the filter 220, during which foreign objects or harmful gases in the air can be removed.

[0142] The fan device 300 can be configured on the upper side of the filter 220 to blow the air passing through the filter 220 to the first tower 110 and the second tower 120.

[0143] The fan assembly 300 includes a fan housing 360, a fan motor 310 disposed inside the fan housing 360, and a fan 320 rotated by the fan motor 310.

[0144] The fan motor 310 can be positioned above the fan 320, and the motor shaft of the fan motor 310 can be connected to the fan 320, which is positioned below. A motor housing 330 for mounting the fan motor 310 can be positioned above the fan 320.

[0145] The motor housing 330 may have a shape that surrounds the entire fan motor 310. Since the motor housing 330 surrounds the entire fan motor 310, the flow resistance between it and the air flowing from the bottom to the top can be reduced. Unlike this embodiment, the motor housing 330 may be formed to only surround the lower part of the fan motor 310.

[0146] The motor housing 330 may include a lower motor housing 332 and an upper motor housing 334. At least one of the lower motor housing 332 and the upper motor housing 334 may be coupled to the housing 100, and the lower motor housing 332 may be coupled to the housing 100. After the fan motor 310 is disposed on the upper side of the lower motor housing 332, the fan motor 310 may be surrounded by covering the upper motor housing 334.

[0147] The motor shaft of the fan motor 310 can pass through the lower motor housing 332 and be assembled to the fan 320 located on the lower side.

[0148] The fan 320 may include: a hub, which is coupled to the motor shaft of the fan motor 310; a shroud, which is spaced apart from the hub; and a plurality of blades connecting the hub and the shroud.

[0149] Air is drawn into the inside of the shroud through filter 220 and then pressurized and flowed by the rotating blades. The hub is disposed above the blades, and the shroud is disposed below the blades. The hub may be formed into a downwardly recessed bowl shape, and a portion of the lower part of the lower motor housing 332 may be inserted into the hub.

[0150] Fan 320 can use a diagonal flow fan. A diagonal flow fan is characterized by drawing in air around a rotating axis and expelling air radially, with the expelled air being formed at an angle relative to the axial direction.

[0151] Because the airflow moves from bottom to top, a significant flow loss occurs due to the change in flow direction when air is ejected radially, as is the case with a typical centrifugal fan.

[0152] Because the diagonal-flow fan ejects air radially upwards, it minimizes airflow loss.

[0153] A diffuser 340 may be configured on the upper side of the fan 320, and the diffuser 340 guides the airflow caused by the fan 320 in an upward direction.

[0154] The diffuser 340 performs the function of further reducing the radial component and strengthening the upward airflow component in the airflow blown from the fan 320.

[0155] The fan housing 360 is cylindrical, with openings on its upper and lower sides. A diffuser 340 can be positioned above the openings of the fan housing 360. A motor housing 330 can be positioned between the diffuser 330 and the fan 320.

[0156] To minimize the vertical height of the motor housing, the lower end of the motor housing 330 is inserted into the fan 320, allowing it to overlap with the fan 320. Conversely, the upper end of the motor housing 330 is inserted into the diffuser 340, also allowing it to overlap with the diffuser 340. The lower end of the motor housing 330 can be configured to be higher than the lower end of the fan 320, and the upper end of the motor housing 330 can be configured to be lower than the upper end of the diffuser 340.

[0157] To optimize the mounting position of the motor housing 330, the upper side of the motor housing 330 is disposed inside the tower base 130, and the lower side of the motor housing 330 can be disposed inside the lower housing 210. In contrast to this embodiment, the motor housing 330 can be disposed inside either the tower base 130 or the lower housing 210.

[0158] An intake grille 350 may be disposed inside the lower housing 210. When the filter 220 is separated, the intake grille 350 prevents the user's fingers from entering the fan 320 side. The intake grille 350 may be disposed on the lower side of the fan housing 360. The intake grille 350 and the fan housing 360 may be manufactured as an integral part, or they may be manufactured as separate parts from the fan housing 360 and assembled therefrom.

[0159] The intake grille 350 can be made into a structure that allows air to pass through, and the intake grille 350 can be made into a grille, a circle, or other shapes.

[0160] The filter 220 can be configured on the lower side of the intake grille 350, and the fan 320 can be configured on the upper side. A plurality of through holes are formed in the intake grille 350 in the vertical direction to allow airflow.

[0161] The space between the intake grille 350 and the discharge outlets 117 and 127 inside the housing 100 is defined as the blowing space 102. The internal space of the first tower 110 and the second tower 120, which have discharge outlets 117 and 127 formed inside the housing 100, is defined as the discharge space 103. The discharge space 103 can be divided into a first discharge space 103a, which represents the internal space of the first tower 110, and a second discharge space 103b, which represents the internal space of the second tower 120.

[0162] After the external air of the blower 1 flows into the filter cavity 221 through the air inlet 211, it passes through the blowing space 102 and the discharge space 103 and is discharged to the outside of the blower 1 through the discharge outlets 117 and 127.

[0163] A substrate cover 230 for accommodating control devices 232 and 233 may be disposed on the lower side of the filter 220. The filter 220 may be disposed on the upper side of the substrate cover 230, and may be placed on the top surface of the substrate cover 230.

[0164] A space 230s for accommodating control devices 232 and 233 is formed inside the substrate cover 230. The control devices 232 and 233 can be divided into: a first control device 232, which controls the operation of the drive unit 700 and the drive of the Coanda destroyer 400; and a second control device 233, which controls the drive of the fan device 300.

[0165] At least a portion of the drive motor 710 can be disposed within the internal space 230s of the substrate cover 230. The drive motor 710 can rotate within the substrate cover 230. The control devices 232, 233 and the drive motor 710 are disposed on the upper side of the rotating plate 500. Therefore, the control devices 232, 233 and the drive motor 710 can rotate together with the rotating plate 500.

[0166] The control devices 232 and 233 and the drive motor 710 are electrically connected and arranged together in the internal space 230s of the substrate cover 230, thereby enabling integrated management of electrical components.

[0167] A drive unit 700 for rotating the blower 1 in a circumferential direction can be disposed on the lower side of the substrate cover 230. The drive unit 700 can rotate the lower housing 210, substrate cover 230, filter 220, fan device 300, first tower 110, and second tower 120 in a circumferential direction. The drive unit 700 can simultaneously rotate all structures disposed in the air supply space 201 inside the lower housing 210 and all structures disposed inside the tower housing 140.

[0168] An air guide 160 may be configured in the discharge space 103, which switches the flow direction of upward-flowing air to a horizontal direction. A plurality of air guides 160 may be configured vertically spaced apart.

[0169] The air guide 160 can switch the flow direction of air flowing from the bottom to the top to a horizontal direction. The air whose flow direction has been switched can be discharged to the outside of the blower 1 through the discharge ports 117 and 127.

[0170] When it is necessary to distinguish between air guides, the air guide disposed inside the first tower 110 is referred to as the first air guide 161, and the air guide disposed inside the second tower 120 is referred to as the second air guide 162.

[0171] When viewed from the front, the first air guide 161 may be attached to the inner wall 115 and / or the outer wall 114 of the first tower 110.

[0172] In order to guide the air flowing from the lower side to the first outlet 117, the first air guide 161 may have an upper convex curved shape with the front side lower than the rear side.

[0173] The rear end 161b of the first air guide 161 can be configured adjacent to the first discharge port 117 and can be connected to the rear end 113 of the first tower 110.

[0174] At least a portion of the left end 161c of the first air guide 161 may be in close contact with or connected to the left side wall 114 of the first tower 110. At least a portion of the right end 161d of the first air guide 161 may be in close contact with or connected to the right side wall 115 of the first tower 110.

[0175] The second air guide 162 is formed to be symmetrical to the first air guide 161, therefore, the description of the second air guide 162 can also be applied to the description of the first air guide 161. Specifically, the rear end 161b of the first air guide 161 can correspond to the rear end of the second air guide 162b, the left end 161c of the first air guide 161 can correspond to the left end 162c of the second air guide 162, and the right end 161d of the first air guide 161 can correspond to the right end 162d of the second air guide 162.

[0176] The first outlet 117 is formed between the front end 112 and the rear end 113 of the first tower 110, closer to the rear end 113. The air discharged from the first outlet 117 can flow along the first inner wall 115 through the Coanda effect and can flow towards the front end 112.

[0177] The first discharge port 117 includes: a first boundary 117a, forming an air discharge side (front end in this embodiment) edge; a second boundary 117b, forming a side (rear end in this embodiment) edge opposite to the air discharge side; an upper boundary 117c, forming an upper edge of the first discharge port 117; and a lower boundary 117d, forming a lower edge of the first discharge port 117.

[0178] The first boundary 117a and the second boundary 117b can be formed to be parallel to each other, and the upper boundary 117c and the lower boundary 117d can be formed to be parallel to each other.

[0179] The first boundary 117a and the second boundary 117b can be formed to be inclined relative to the vertical direction V, and the rear end 113 of the first tower 110 can also be formed to be inclined relative to the vertical direction V.

[0180] The inclination a1 of the first boundary 117a and the second boundary 117b relative to the vertical direction V can be four degrees, and the inclination a2 of the rear end 113 can be three degrees. That is, the inclination a1 of the outlet 117 can be greater than the inclination a2 of the rear end 113 of the first tower 110.

[0181] The second outlet 127 can be formed to be approximately symmetrical to the first outlet 117, and the description of the second outlet 127 can also be applied to the first outlet 117. Therefore, the second outlet 127 and the rear end 123 of the second tower 120 can be formed to be inclined relative to the vertical direction V, and the inclination angle a1 of the second outlet 127 can be formed to be greater than the inclination angle a2 of the rear end 123 of the second tower 120.

[0182] The following is for reference Figure 9 and Figure 10 This describes the structure that induces the Coanda effect in the air supply space 105 and the Coanda disruptor 400 structure that switches the flow direction of the air discharged through the outlets 117 and 127.

[0183] The first outlet 117 of the first tower 110 can be configured to face the second tower 120, and the second outlet 127 of the second tower 120 can be configured to face the first tower 110.

[0184] Air discharged from the first outlet 117 flows along the inner wall 115 of the first tower 110 due to the Coanda effect. Air discharged from the second outlet 127 flows along the inner wall 125 of the second tower 120 due to the Coanda effect.

[0185] The towers 110 and 120 of the blower 1 may further include a first discharge housing 170 and a second discharge housing 180. Although not shown, the first discharge housing 170 may be made as an inner housing disposed inside the first tower 110, and an air guide (not shown) may be disposed inside the first discharge housing 170. The second discharge housing 180 may also be made as an inner housing disposed inside the second tower 120, and an air guide (not shown) may be disposed inside the second discharge housing 180.

[0186] When the first ejection housing 170 and the second ejection housing 180 are made in the form of an inner housing, the air in the blowing space 102 can be directly received.

[0187] The first discharge port 117 can be formed in the first discharge housing 170, and the first discharge housing 170 can be assembled into the first tower 110. The second discharge port 127 can be formed in the second discharge housing 180, and the second discharge housing 180 can be assembled into the second tower 120.

[0188] The first discharge shell 170 can be configured to penetrate the inner wall 115 of the first tower 110, and the second discharge shell 180 can be configured to penetrate the inner wall 125 of the second tower 120.

[0189] The first tower 110 may have a first discharge opening 118 provided with a first discharge housing 170, and the second tower 120 may have a second discharge opening 128 provided with a second discharge housing 180.

[0190] The first discharge housing 170 may include: a first discharge guide 172 forming a first discharge outlet 117 and disposed on the air discharge side of the first discharge outlet 117; and a second discharge guide 174 forming the first discharge outlet 117 and disposed separately from the first discharge guide 172.

[0191] The outer surfaces 172a and 174a of the first ejection guide 172 and the second ejection guide 174 can form part of the inner wall 115 of the first tower 110.

[0192] The inner side of the first discharge guide 172 is connected to the first discharge space 103a, and the outer side is connected to the air supply space 105. The inner side of the second discharge guide 174 is connected to the first discharge space 103a, and the outer side is connected to the air supply space 105.

[0193] The outer surface 172a of the first ejection guide 172 can be formed as a curved surface, and the outer surface 172a can be formed as a surface continuous with the first inner sidewall 115.

[0194] The outer surface 174a of the second discharge guide 174 can be formed as a surface continuous with the first inner wall 115, and the inner surface 174b of the second discharge guide 174 can be formed as a curved surface. The inner surface 174b can be formed as a curved surface continuous with the inner surface of the first outer wall 115. With this structure, the air in the first discharge space 103a can be guided to flow toward the first discharge guide 172.

[0195] A first discharge port 117 is formed between the first discharge guide 172 and the second discharge guide 174, and the air in the first discharge space 103a can be discharged into the air supply space 105 through the first discharge port 117.

[0196] Specifically, air in the first discharge space 103a is discharged between the outer surface 172a of the first discharge guide 172 and the inner surface 174b of the second discharge guide 174, and the distance between the outer surface 172a of the first discharge guide 172 and the inner surface 174b of the second discharge guide 174 is defined as the discharge interval 175. The first discharge guide 172 and the second discharge guide 174 form a defined channel.

[0197] The discharge interval 175 can be configured such that the width of the middle portion 175b is narrower than that of the inlet 175a and the outlet 175c. The middle portion 175b is defined as the shortest distance between the second boundary 117b and the outer surface 172a.

[0198] The cross-sectional area gradually narrows from the inlet 175a of the discharge interval 175 to the middle section 175b, and then the cross-sectional area widens again from the middle section 175b to the outlet 175c. The middle section 175b is located inside the first tower 110, and when viewed from the outside, the outlet 175c of the discharge interval 175 can be regarded as the discharge outlet 117.

[0199] In order to induce the Coanda effect, the radius of curvature of the inner side 174b of the second ejection guide 174 can be formed to be larger than the radius of curvature of the outer side 172a of the first ejection guide 172.

[0200] The center of curvature of the outer surface 172a of the first ejection guide 172 is located in front of the outer surface 172a and is formed inside the first ejection space 103a. The center of curvature of the inner surface 174b of the second ejection guide 174 is located on the side of the first ejection outlet 117 and is formed inside the first ejection space 103a.

[0201] The second discharge housing 180 may include: a first discharge guide 182 forming a second discharge outlet 127 disposed on the air discharge side of the second discharge outlet 127; and a second discharge guide 184 forming a second discharge outlet 127, disposed spaced apart from the first discharge guide 182, with a discharge gap 185 formed between the first discharge guide 182 and the second discharge guide 184.

[0202] The second ejection housing 180 can be configured to be approximately symmetrical to the first ejection housing 170, and the description of the first ejection housing 170 can also be applied to the second ejection housing 180.

[0203] The blower 1 may also include an air flow converter 400 that switches the flow direction of the air flowing in the air supply space 105.

[0204] The Coanda Destroyer 400 can switch the horizontal airflow in the air supply space 105 into an upward airflow.

[0205] The Coanda breaker 400 includes a first Coanda breaker 401 disposed in the first tower 110 and a second Coanda breaker 402 disposed in the second tower 120. The first Coanda breaker 401 and the second Coanda breaker 402 can be configured symmetrically from left to right, and their configurations can be identical.

[0206] The Coanda breaker 400 includes: a guide board 410 disposed in towers 110 and 120 and protruding toward the air supply space 105; a guide motor 420 providing driving force for moving the guide board 410; a power transmission member (not shown) transmitting the driving force generated by the guide motor 420 to the guide board 410; and a panel guide 440 disposed inside towers 110 and 120 to guide the movement of the guide board 410.

[0207] The guide panel 410 can be hidden inside the towers 110 and 120, and at least a portion of it can protrude into the air supply space 105 when the guide motor 420 is running.

[0208] The guide panel 410 includes a first guide panel 411 disposed on the first tower 110 and a second guide panel 412 disposed on the second tower 120.

[0209] A panel slit 119 is formed that penetrates the inner wall 115 of the first tower 110, and a panel slit 129 is formed that penetrates the inner wall 125 of the second tower 120, so that the guide panel 410 protrudes into the air supply space 105.

[0210] The panel slot formed on the first tower 110 is called the first panel slot 119, and the panel slot formed on the second tower 120 is called the second panel slot 129.

[0211] The first panel slit 119 and the second panel slit 129 can be formed symmetrically from left to right, and the first panel slit 119 and the second panel slit 129 can be formed to extend relatively long in the vertical direction. The first panel slit 119 and the second panel slit 129 can be configured to be inclined relative to the vertical direction V.

[0212] The front end 112 of the first tower 110 can be tilted at three degrees, and the first panel slit 119 can be tilted at four degrees. The front end 122 of the second tower 120 can be tilted at three degrees, and the second panel slit 129 can be tilted at four degrees.

[0213] The guide panel 410 can be formed as a flat or curved plate shape, can be extended in a long vertical direction, and can be positioned in front of the air supply space 105.

[0214] The guide panel 410 blocks the horizontal airflow of air flowing in front of the blower 1 through the air supply space 105, and switches the air flowing in the air supply space 105 to flow in an upward direction.

[0215] The inner ends 411a of the first guide panel 411 and the inner ends 412a of the second guide panel 412 block the airflow in front of the blower 1 by contacting or approaching each other, thereby guiding the airflow upward. In contrast, a single guide panel 410 may be placed in close contact with the opposite side of the tower and perform the above-described function.

[0216] When the Coanda breaker 400 does not protrude into the air supply space 105, the inner end 411a of the first guide panel 411 can close the first panel slit 119, and the inner end 412a of the second guide panel 412 can close the second panel slit 129.

[0217] When the Coanda breaker 400 is in operation and protrudes into the air supply space 105, the inner end 411a of the first guide panel 411 can pass through the first panel slit 119 and protrude into the air supply space 105, and the inner end 412a of the second guide panel 412 can pass through the second panel slit 129 and protrude into the air supply space 105.

[0218] The first guide panel 411 and the second guide panel 412 can protrude into the air supply space 105 by rotation. In contrast, at least one of the first guide panel 411 and the second guide panel 412 can also slide linearly and protrude into the air supply space 105.

[0219] When viewed from above, the first guide panel 411 and the second guide panel 412 may be arc-shaped. The first guide panel 411 and the second guide panel 412 form a predetermined radius of curvature, with the center of curvature located within the air supply space 105.

[0220] The panel guide 440 can be assembled to the outer walls 114 and 124 of the towers 110 and 120. The panel guide 440 can be arranged radially outward with reference to the guide panel 410. This structure can reduce the frictional resistance generated in the air flowing in the discharge space 103.

[0221] The following is for reference Figure 11 and Figure 12 This describes the internal structure of the air supply unit 200.

[0222] The fan housing 360 may include a flare 363 that directs air passing through the filter 220 to the fan 320.

[0223] The flare 363 can be configured on the upper side of the filter 220, and the intake grille 350 can be configured between the filter 220 and the flare 363.

[0224] The flare 363 can be an annular shape with a defined inner diameter BD, and the inner side can be open in the vertical direction. The inner diameter BD can be understood as the diameter of the inner circumferential surface 363a of the flare 363, and an airflow channel toward the fan 320 can be formed on the inner side of the flare 363.

[0225] The fan 320, connected to the rotating shaft 311, generates suction force on the air in the hollow filter 221 by rotating. The air in the hollow filter 221 can flow to the fan housing 360 through the suction grille 350 and the horn 363.

[0226] The filter 220 can be a cylindrical shape with a filter cavity 221. Air flowing into the lower housing 210 through the air inlet 211 can flow into the filter cavity 221 through the outer peripheral surface 220a and the inner peripheral surface 220b of the filter 220. The inflowing air can flow from the outer peripheral surface 220a to the inner peripheral surface 220b of the filter 220 while passing through the pre-filter, high-efficiency air filter, and deodorizing filter disposed between the outer peripheral surface 220a and the inner peripheral surface 220b, and flow into the filter cavity 221 with the contained foreign matter filtered out.

[0227] The filter 220 can be supported by a filter frame 222 that restricts the movement of the filter 220 in the radially outward direction. The filter frame 222 can extend vertically and can contact the outer peripheral surface 220a of the filter 220. A plurality of filter frames 222 can be arranged circumferentially, up to three. The filter 220 can be introduced and removed through the area where no filter frame 222 is provided. The lower housing 210 can be detachably disposed in the drive unit 700, allowing the user to remove and clean the filter 220 after separating the lower housing 210.

[0228] The filter frame 222 can be connected to the substrate cover 230 disposed on the lower side of the filter 220. The substrate cover 230 contacts the bottom surface of the filter 220 and can support the filter 220. The substrate cover 230 may include an outer wall 231 that extends in a circumferential direction and is supported by the drive unit 700.

[0229] The outer wall 231 of the cover may include: a top surface 231a of the outer wall of the cover extending in a circumferential direction; a frame connecting portion 231b protruding upward from the top surface 231a of the outer wall of the cover; and a fastening hole 231c formed in the frame connecting portion 231b.

[0230] The filter frame 222 can be connected to the outer wall 231 of the cover via a specified fastening member (not shown) through the fastening hole 231c, and can be fixed by the base plate cover 230.

[0231] A drive unit 700 for rotating the blower 1 is disposed on the lower side of the substrate cover 230. The drive unit 700 includes: a base 600 in contact with the ground; and a rotating plate 500 rotatably disposed on the upper side of the base 600.

[0232] The substrate cover 230 can be disposed on the upper side of the rotating plate 500, and the rotating plate 500 can rotate while supporting the load of all structures 100, 110, 120, 130, 140, 200, 210, 220, 230, 300 disposed on the upper side of the substrate cover 230 and rotating.

[0233] The following is for reference Figures 13 to 23 This describes the structure and operation of the rotating plate 500 and the base 600 according to an embodiment of the present invention.

[0234] Reference Figure 14 The blower 1 includes: a base 600; a rotating plate 500 connected to the housing 100 and rotatably disposed on the upper side of the base 600; and a drive unit 700 that causes the rotating plate 500 to rotate on the upper side of the base 600.

[0235] Reference Figure 17 The blower 1 includes: a shaft bearing 560, disposed between the base 600 and the rotating plate 500, supporting the rotation of the rotating plate 500; and a wire retainer 570, fixedly disposed on the rotating plate 500, for fixing the wire disposed on the upper side of the rotating plate 500.

[0236] The rotating plate 500 is rotatably disposed on the upper side of the base 600 and supported by the base 600. When the rotating plate 500 rotates, the base 600 supports the normal stress and shear stress generated by all structures disposed on the upper side of the base 600, including the rotating plate 500.

[0237] Reference Figure 13 The rotating plate 500 includes: a plate 510; an outer peripheral cover 520 extending downward from the outer periphery of the plate 510; and a shaft body 530 disposed at the rotation center of the plate 510, protruding toward the base 600, and supporting the rotation of the plate 510.

[0238] Reference Figure 14 and Figure 15 The overall shape of plate 510 can be circular, with a through-hole 512 opening vertically at its center. Rotating plate 500 has a through-hole 512 opening vertically at its center in the shaft body 530. The following wires can be arranged through the through-hole 512.

[0239] Reference Figure 13The shaft body 530 extends downward from the plate 510. The shaft body 530 may have a hollow annular shape. A shaft through-hole 512 is formed inside the shaft body 530. The shaft body 530 includes a first shaft body 532 forming the outer periphery of the shaft through-hole 512 and a second shaft body 534 disposed on the outer periphery of the first shaft body 532. The first shaft body 532 protrudes downward more than the second shaft body 534. Therefore, the first shaft body 532 and the second shaft body 534 are formed in a stepped manner relative to each other.

[0240] The outer peripheral surface 532a of the first shaft body 532 is configured to contact the inner peripheral surface 562a of the shaft bearing 560. The lower surface 534a of the second shaft body 534 can be configured to contact the upper surface 562b of the shaft bearing 560. Therefore, the shaft bearing 560 can be stably configured by means of the first shaft body 532 and the second shaft body 534.

[0241] Reference Figure 13 The overall shape of the shaft bearing 560 can be cylindrical, and a portion of the shaft body 530 can extend through the inner side of the shaft bearing 560. (Refer to...) Figure 13 The first shaft body 532 is configured to pass through the inner side of the shaft bearing 560.

[0242] Reference Figure 14 A pair of fastening parts 536 facing each other can be formed in the shaft through-hole 512. The fastening parts 536 can be fastened to the wire retainer 570 by fastening members 537 such as bolts.

[0243] A portion of the central part of the fastening part 536 is formed by inserting into the shaft through-hole 512. The fastening part 536 has a cylindrical shape extending in the vertical direction and can be configured to protrude into the shaft through-hole 512.

[0244] Reference Figure 14 A motor mounting portion 514 for fixing the drive motor 710 of the drive unit 700 is disposed on the upper surface of the plate 510. The motor mounting portion 514 may have a structure for mounting the drive motor 710. The drive motor 710 can be fastened to the rotating plate 500 by an additional fastening device (not shown) while it is mounted in the motor mounting portion 514. The drive motor 710 may be disposed at a position radially spaced from the rotation center of the plate 510.

[0245] Reference Figure 16 A plurality of ball bearings 540 are disposed on the lower surface 510b of the plate 510 to support the load applied to the rotating plate 500. The plurality of ball bearings 540 are disposed at a position spaced radially from the shaft body 530.

[0246] The ball bearing 540 may be arranged radially outward from the base gear 642 of the base 600 described below. A bearing retainer 542 for fixing the arrangement of the ball bearing 540 is provided on the lower surface 510b of the plate 510. The bearing retainer 542 is configured to protrude from the lower surface 510b of the plate 510 toward the base 600, thereby fixing the arrangement of the ball bearing 540.

[0247] The ball bearing 540 may have a spherical shape that allows it to rotate freely in the bearing retainer 542. The ball bearing 540 is configured to contact the upper part of the base 600 located on the lower side. Therefore, when the rotating plate 500 rotates, the ball bearing 540 contacts the upper part of the base 600, which can distribute the load applied to the rotating plate 500.

[0248] Reference Figure 16 A plurality of ball bearings 540 are disposed on the lower surface 510b of plate 510. The plurality of ball bearings 540 may be spaced apart in the circumferential direction. (Refer to...) Figure 16 The plurality of ball bearings 540 are arranged at equal intervals from the rotation center of the rotating plate 500. However, this is only one embodiment, and the plurality of ball bearings 540 may also be arranged at different intervals from the rotation center of the rotating plate 500.

[0249] Reference Figure 16 A plurality of support bearings 550 are provided on the lower surface 510b of the plate 510, and the plurality of support bearings 550 prevent one side of the housing 100 from tilting off the base 600.

[0250] The plurality of support bearings 550 are arranged radially further away from the rotation center of the rotating plate 500 than the plurality of ball bearings 540. The plurality of support bearings 550 may be arranged between the corner ribs 644 of the base 600 and the outer peripheral cover 520 of the rotating plate 500.

[0251] Reference Figure 13 The support bearing 550 may include: a support protrusion 552 formed to protrude downward from the rotating plate 500; a support shaft 554 connected to the support protrusion 552; and a wheel 556 through which the support shaft 554 passes.

[0252] The support protrusion 552 may have an insertion hole (not shown) for the support shaft 554 to be inserted into the support protrusion 552 from above.

[0253] The support shaft 554 can support the wheel 556 and can be used with screws or pins. The support shaft 554 can be inserted into and fixed to the support protrusion 552 to support the wheel 556 and prevent the wheel 556 from falling downward.

[0254] Wheel 556 can be rotatably disposed between support protrusion 552 and support shaft 554. Wheel 556 can use rollers, and wheel 556 can rotate about support shaft 554 as the axis of rotation.

[0255] The wheel 556 may be positioned below the outer periphery of the upper body 630 of the base 600. The wheel 556 may be positioned below the outer rib 648 of the base 600 described below. Therefore, when the housing 100 vibrates or is subjected to external force, the upper surface 556a of the wheel 556 contacts the lower surface 648a of the outer rib 648, which can prevent one side of the housing 100 from vibrating upwards.

[0256] When the rotating plate 500 rotates and the wheel 556 contacts the outer rib 648 of the base 600, the wheel 556 can rotate about the support shaft 554 as the axis of rotation. This can also be expressed as the wheel 556 rotating on its own axis about the support shaft 554 and revolving around the center of rotation O.

[0257] Reference Figure 13 The shaft bearing 560 may include: a first layer 562 that rotates integrally with the rotating plate 500; and a second layer 564 configured to surround the first layer 562 and rotate integrally with the base 600.

[0258] The first layer 562 may be arranged radially inward compared to the second layer 564, and the outer peripheral surface of the first layer 562 may contact the inner peripheral surface of the second layer 564. The second layer 564 may be arranged radially inward compared to the rotating shaft cover 636 of the base 600, and the outer peripheral surface of the second layer 564 may contact the inner peripheral surface of the shaft body 530.

[0259] The first layer 562 can rotate together with the rotating plate 500. Conversely, the second layer 564 can be fixedly disposed in the rotating shaft cover 515, or it can remain stationary while the rotating plate 500 rotates. The first layer 562 can support the rotation of the shaft body 530, and the second layer 564 can support the rotation of the first layer 562. Therefore, lubricating oil can be injected between the first layer 562 and the second layer 564.

[0260] The shaft bearing 560 can be disposed on the rotating plate 500 to surround the outer peripheral surface 532a of the shaft body 530, and can be disposed on the base 600 in such a way as to be fixed to the inner peripheral wall 638 of the rotating shaft cover 515.

[0261] The base 600 is in contact with the ground and can be fixedly mounted on the ground. The base 600 may have a bowl shape forming a space for housing electrical wires inside. The base 600 may have a structure to prevent the overall structure of the blower 1 from being inverted.

[0262] Reference Figure 15The base 600 may include: a lower body 610 forming an inner space 610s; an upper body 630 disposed on the upper side of the lower body 610 and on the upper side of the inner space of the lower body 610; and a bottom body 620 disposed on the lower side of the lower body 610 and in contact with the ground.

[0263] Reference Figure 13 The overall shape of the lower body 610 can be bowl-shaped, forming an inner space 610s.

[0264] The lower body 610 may include: a lower plate 612; and an outer wall 614 extending obliquely upward from the edge of the lower plate 612.

[0265] The overall shape of the lower plate 612 can be circular. The outer wall 614 of the main body can extend in the circumferential direction and can be formed inclined radially outward. An electrical wire hole 614a through which the power supply line 10 passes can be formed on one side of the outer wall 614 of the main body.

[0266] Reference Figure 13 The base body 620 may include: a base plate 622 formed to contact the ground; a support platform 62 disposed at the edge of the base plate 622 to prevent the blower 1 from being overturned; and a fastening boss 623 extending upward from the base plate 622 and fastened to the lower plate 612.

[0267] The base plate 622 can be formed to approximately the same size as the lower plate 612. The support platform 62 can have a structure that slopes towards the ground from the edge of the lower plate 612 to prevent the entire structure of the blower 1 from tipping over. The support platform 62 can be formed in a ring shape at the outer periphery of the base plate 622.

[0268] The support platform 62 includes: an inner support platform 626 extending upward from the edge of the base plate 622; and an outer support platform 628 configured to slope downward from the inner support platform 626. The inner support platform 626 may be configured to contact the edge portion of the lower plate 612 at its upper end. The outer support platform 628 extends radially outward, and its outer peripheral end may be formed to contact the ground.

[0269] Reference Figure 15 The upper body 630 may include: an upper plate 632; a rotating shaft cover 636 disposed at the center of the upper plate 632 and protruding toward the rotating plate 500; a corner rib 644 extending upward from the edge of the upper plate 632; and a base gear 642 protruding upward from the upper part of the upper plate 632 and forming a gear on one side in a manner that meshes with the drive unit 700.

[0270] The upper plate 632 may have a generally circular shape. A shaft insertion port 634 with an opening in the vertical direction is formed at the center of the upper plate 632. A rotating shaft cover 636 may be disposed on the outer periphery of the shaft insertion port 634.

[0271] Reference Figure 13 The overall shape of the rotating shaft cover 636 can be cylindrical. The rotating shaft cover 636 can provide space for the shaft body 530 to be inserted inside. The rotating shaft cover 636 can be configured to protrude upward from the upper plate 632. The rotating shaft cover 636 may include: an inner peripheral wall 638 forming a space for the shaft body 530 to be inserted; and an inner protrusion 640 protruding radially inward from the lower end of the inner peripheral wall 638.

[0272] A shaft bearing 560 may be disposed inside the rotating shaft cover 636. The rotating shaft cover 636 supports the shaft bearing 560 and can prevent the shaft bearing 560 from separating from the shaft body 530.

[0273] The inner peripheral wall 638 can be configured to contact the outer peripheral surface of the second layer 564 of the shaft bearing 560. The inner protrusion 640 can support the lower part of the shaft bearing 560. The upper surface of the inner protrusion 640 can contact the lower surface of the second layer 564 of the shaft bearing 560.

[0274] Reference Figure 15 The base gear 642 has a ring shape and can be configured to protrude from the upper side of the upper plate 632. The center of the base gear 642 can be formed to be the same as the center of the rotating shaft cover 636 and larger than the radius of the rotating shaft cover 636.

[0275] Reference Figure 15 and Figure 17 The base gear 642 may have a gear formed along its outer peripheral surface that meshes with the drive gear 720 of the drive unit 700, which will be described later. The base gear 642 may be fixedly mounted on the upper plate 632. Therefore, the rotation of the drive gear 720 along the outer peripheral surface of the base gear 642 can cause the rotating plate 500 to rotate.

[0276] Reference Figure 13 The base gear 642 can be configured between the rotating shaft body 530 and the corner rib 644. The base gear 642 can be configured between the shaft bearing 560 and the ball bearing 540.

[0277] Reference Figure 13 The corner rib 644 has a structure that extends upward from the edge of the upper plate 632. The corner rib 644 contacts the support bearing 550, thereby preventing one side of the edge portion of the rotating plate 500 from tilting upward.

[0278] The edge rib 644 includes: an annular vertical rib 646 protruding upward from the outer periphery of the upper plate 632; and an outer rib 648 extending radially outward from the upper end of the vertical rib 646. The outer rib 648 can be positioned higher than the wheel 556 of the support bearing 550. Therefore, when the edge of the rotating plate 500 moves upward, the upper surface 556a of the wheel 556 of the support bearing 550 and the lower surface 648a of the outer rib 648 can come into contact.

[0279] Reference Figures 17 to 18A The upper body 630 includes: a gear support rib 650 to strengthen the rigidity of the base gear 642; a rigid rib 652 to strengthen the rigidity of the upper plate 632; a wire fixing protrusion 654 to fix the wires disposed in the wire holes 614a of the lower body 610; and a wire guide rib 660 to prevent interference from the wires 10 disposed on the lower side of the upper plate 632.

[0280] The gear support rib 650 protrudes upward from the upper plate 632 and is disposed on the inner side of the base gear 642. The gear support rib 650 can be connected to the inner circumferential surface of the base gear 642 to enhance the rigidity of the base gear 642.

[0281] Reference Figure 17 The gear support rib 650 can be disposed on a portion of the inner circumferential surface of the base gear 642. The gear support rib 650 can be disposed on the inner side of the base gear 642 within the range of movement of the gear 720 driven by the drive motor 710. However, as another embodiment, the gear support rib 650 can also be disposed on the entire inner circumferential surface of the base gear 642.

[0282] Reference Figure 17 Rigid rib 652 can be disposed on the upper side of upper plate 632. Rigid rib 652 can be disposed in the space between base gear 642 and rotating shaft cover 636. Rigid rib 652 includes: first rigid rib 652a, extending radially from rotating shaft cover 636; and second rigid rib 652b, configured as a ring shape with a radius larger than that of rotating shaft cover 636.

[0283] Reference Figure 13 The wire fixing protrusion 654 protrudes from the portion of the lower body 610 where the wire hole 614a is formed, towards the lower side of the upper plate 632. Therefore, the wire fixing protrusion 654 can fix the wire passing through the wire hole 614a. The wire 10 is also shaped to be mounted on the wire fixing protrusion 654, so that the position of the portion mounted on the wire fixing protrusion 654 can be fixed. Therefore, it is possible to prevent the length of the wire 10 exposed to the outside through the wire hole 614a from becoming longer or shorter.

[0284] The wire guide 660 is disposed on the lower surface of the upper plate 632. The wire guide 660 can prevent the wires disposed between the lower body 610 and the upper body 630 from interfering with each other.

[0285] One side of the wire 10, which is disposed between the lower body 610 and the upper body 630, is fixed to the wire fixing protrusion 654, and the other side is fixed to the wire fixing member 578 of the wire retainer 570. Therefore, the length of the wire 10 disposed between the lower body 610 and the upper body 630 can be maintained constant.

[0286] However, as the wire retainer 570 rotates together with the rotating plate 500, the distance between the wire fixing member 578 and the wire fixing protrusion 654 of the wire retainer 570 can change, thereby potentially altering the arrangement of the wires 10 positioned between the lower body 610 and the upper body 630. The wire guide rib 660 secures a portion of the wire arrangement between the lower body 610 and the upper body 630, thus preventing interference between the wires.

[0287] The wire guide rib 660 is configured to protrude downward from the lower part of the upper plate 632.

[0288] Reference Figure 18A The wire guide 660 in the first embodiment may include an outer guide 662, an inner guide 664, and an additional 666.

[0289] The outer guide rib 662 may have a ring shape with one side cut open. The outer guide rib 662 may form a cut area for arranging the wire 10 in the area where the wire fixing protrusion 654 is provided.

[0290] The inner guide rib 664 is positioned further radially inward than the outer guide rib 662. The inner guide rib 664 may be shorter than the outer guide rib 662.

[0291] The inner guide rib 664 can be formed by a single component. The inner guide rib 664 can be divided into a first inner guide rib 664 spaced apart from the outer guide rib 662 by a predetermined interval and a second inner guide rib 664 that can be expanded by a predetermined interval from the outer guide rib 662. The first inner guide rib 664 can be disposed in the area adjacent to the wire fixing protrusion 654.

[0292] The inner guide rib 664 and the outer guide rib 662 can have an arc shape. The central angle θ2 of the arc formed by the inner guide rib 664 can be smaller than the central angle θ1 of the arc formed by the outer guide rib 662.

[0293] The additional rib 666 can be disposed between the wire fixing protrusion 654 and the rotation center of the upper plate 632. The additional rib 666 can extend from one end of the outer guide rib 662. The additional rib 666 extends in the direction in which the inner guide rib 664 is disposed, and the closer it is to the inner guide rib 664, the closer it extends to the rotation center of the upper plate 632. The additional rib 666 can prevent contact between the wires 10.

[0294] The additional rib 666 is disposed between the wire fixing protrusion 654 and the rotation center of the upper plate 632, which can prevent the wires extending from the wire fixing protrusion 654 and the wires extending to the wire retainer 570 from contacting each other.

[0295] Reference Figure 18B In the second embodiment, the wire guide 660 can be composed of an outer guide 662 and an inner guide 664.

[0296] The outer guide rib 662 may have the same shape as the outer guide rib 662 in the first embodiment.

[0297] The inner guide ribs 664 can be arranged in multiples spaced apart in the circumferential direction.

[0298] The inner guide rib 664 includes: a first inner guide rib 664a, disposed adjacent to the wire fixing protrusion 654; and a second inner guide rib 664b, disposed circumferentially spaced from the first inner guide rib 664a. The first inner guide rib 664a may be formed parallel to the outer guide rib 662. The first inner guide rib 664a and the outer guide rib 662 may maintain a constant interval between them. Therefore, a portion of the wire disposed between the lower body 610 and the upper body 630 may be configured to be fixed between the outer guide rib 662 and the first inner guide rib 664a.

[0299] As the second inner guide rib 664b moves away from the first inner guide rib 664a, it can extend in a direction closer to the rotation center of the upper plate 632. That is, the interval between the second inner guide rib 664b and the outer guide rib 662 can increase as it moves away from the first inner guide rib 664a.

[0300] The wire retainer 570 is fixed to the rotating plate 500 and rotates together with the rotating plate 500, fixing the wire 10 on one side. The wire retainer 570 includes: an upper panel 572 fixed to the rotating plate 500; a lower panel 574 spaced downward from the upper panel 572; and a connecting wall 576 connecting the upper panel 572 and the lower panel 574.

[0301] The upper panel 572 is fixed to the shaft body 530 of the rotating plate 500. (See reference...) Figure 13The upper panel 572 can be fastened to the fastening part 536 disposed inside the shaft body 530 by means of the fastening member 537. Therefore, the wire retainer 570 is fixedly disposed on the rotating plate 500 and can rotate together with the rotating plate 500.

[0302] The top panel 572 can have a wire through hole 572a through which a power supply line passes.

[0303] A fastening rib 579, which engages with the fastening part 536, is disposed on the upper side of the top panel 572. The fastening rib 579 protrudes upward from the upper surface of the top panel 572. The fastening rib 579 forms a groove for the fastening part 536 to be inserted, thereby securing the arrangement of the fastening part 536. When the fastening part 536 is inserted into the groove formed in the fastening rib 579, the fastening part 536 can be fastened to the wire retainer 570 by an additional fastening member.

[0304] Reference Figure 15 The fastening rib 579 may include a first fastening rib 579a and a second fastening rib 579b disposed spaced apart from the first fastening rib 579a. The fastening portion 536 may be disposed between the first fastening rib 579a and the second fastening rib 579b.

[0305] The first fastening rib 579a and the second fastening rib 579b can have different shapes from each other. This is based on the structure of the wire through hole 572a. The first fastening rib 579a and the second fastening rib 579b can also have symmetrical shapes.

[0306] The connecting wall 576 may have a generally cylindrical shape. The connecting wall 576 may extend downward from the outer periphery of the upper panel 572. The interior of the connecting wall 576 may be hollow.

[0307] The lower plate 574 may have a structure extending radially outward from the lower end of the connecting wall 576. The lower plate 574 is disposed below the upper plate 632. The upper plate 632 may have a groove formed upward on the portion where the lower plate 574 is disposed. The lower surface of the upper plate 632 and the upper surface of the lower plate 574 may be configured to be spaced apart from each other. Therefore, the wire retainer 570 can rotate stably without contacting the upper plate 632. A wire fixing member 578 for fixing one side of the wire 10 is disposed below the lower plate 574. The wire fixing member 578 can fix the arrangement of the wire below the lower plate 574.

[0308] Reference Figure 19A and Figure 19B This describes the arrangement of wires based on the rotation of the rotating plate 500.

[0309] Even if configured as follows Figure 19A Such a first position P1 or as Figure 19BIn such a second position P2, the arrangement of the wires 10 between the outer guide rib 662 and the inner guide rib 664 can also be fixed.

[0310] Reference Figure 19A The wire 10 disposed between the lower body 610 and the upper body 630 can be divided into: a third wire 10a extending from the wire fixing protrusion 654 to the outer guide rib 662, a first wire 10b disposed between the outer guide rib 662 and the inner guide rib 664, and a second wire 10c extending from the first wire 10b to the wire retainer 570.

[0311] Even if configured in the first position P1, such as 19A, or as... Figure 19B The arrangement of the second position P2, the third wire 10a, and the first wire 10b can also be fixed.

[0312] Reference Figure 19A When the wire fixing protrusion 654 and the wire fixing member 578 are located at a first position P1, arranged at a distance, the ends of the wire fixing protrusion 654 and the inner guide rib 664 are arranged adjacent to each other. (Refer to...) Figure 19A When the wire fixing protrusion 654 and the wire fixing member 578 are in the first position P1, the second wire 10c can form a steep curvature along the direction in which the inner guide rib 664 is arranged. At this time, the inner guide rib 664 can prevent the second wire 10c from contacting the first wire 10b.

[0313] Reference Figure 19B When the wire fixing protrusion 654 and the wire fixing member 578 are located in the second position P2, which is arranged in close proximity, the ends of the wire fixing protrusion 654 and the inner guide rib 664 can be configured in a distant position. (Refer to...)

[0314] Reference Figure 20 The drive unit 700 is configured on the upper and lower sides of the rotating plate 500, which minimizes the space occupied by the drive unit 700 inside the blower 1.

[0315] Reference Figure 21The drive unit 700 includes: a drive motor 710 that generates driving force to rotate a drive shaft; a drive gear 720 that is connected to and rotates the drive shaft 714, causing the rotating plate 500 to rotate; and a bracket 740 that supports the drive shaft 714. The drive unit 700 includes a gear bearing 730, which is disposed between the bracket 740 and the drive shaft 714 or the drive gear 720 to minimize friction between the bracket 740 and the drive shaft 714 or the drive gear 720.

[0316] The drive motor 710 can be disposed on the upper side of the rotating plate 500. A motor slot (not shown) with an opening in the vertical direction can be formed in the rotating plate 500. The drive motor 710 can be fixedly disposed on the motor mounting portion 514 disposed on the upper part of the rotating plate 500. Therefore, the drive motor 710 is fixed to the rotating plate 500 and can rotate together with the rotating plate 500. The drive motor 710 is fixed to the motor mounting portion 514 of the rotating plate 500 and can be supported by the rotating plate 500.

[0317] The overall shape of the drive motor 710 can be cylindrical.

[0318] The drive motor 710 includes: a motor body 712; and a drive shaft 714 extending from the motor body 712 and connected to a drive gear 720.

[0319] The motor body 712 is fixed to the motor fastening part 536. The motor body 712 has a generally cylindrical shape and a fastening protrusion 716 connected to the motor fastening part 536 is formed on one side.

[0320] The drive shaft 714 can rotate when the drive motor 710 is running. A drive gear 720 can be disposed at the end of the drive shaft 714. The drive shaft 714 is configured to pass through a motor slot (not shown). The drive shaft 714 has a strip shape with a circular cross-section. The portion of the drive shaft 714 connected to the drive gear 720 may have a structure in which a portion forms a straight surface. The portion of the drive shaft 714 connected to the drive gear 720 may have a structure with a polygonal cross-section. Therefore, the drive gear 720 can rotate together with the drive shaft 714 when it is connected to the end of the drive shaft 714.

[0321] The drive gear 720 can be configured on the underside of the rotating plate 500. The drive gear 720 can be a spur gear or a pinion.

[0322] Reference Figure 22 and Figure 23The drive gear 720 includes: a gear plate 722, on which a gear is formed on its outer peripheral surface and has a circular plate shape; a gear boss 724, extending from the center of the gear plate 722 toward the drive motor 710, forming a shaft groove 724a for the drive shaft 714 to be inserted; and a gear protrusion 726, extending from the center of the gear plate 722 in the opposite direction to the gear boss 724, and inserted into the center hole 732 of the gear bearing 730.

[0323] The gear boss 724 is connected to one end of the drive shaft 714, allowing the drive gear 720 to rotate together with the drive shaft 714. The cross-section of the shaft groove 724a formed inside the gear boss 724 can have the same shape as the cross-section of the connecting end of the drive shaft 714.

[0324] The gear plate 722 has a circular plate shape and can have a gear shape in which the outer peripheral surface meshes with the base gear 642.

[0325] A bearing groove 722a for arranging the gear bearing 730 can be formed in the lower part of the gear plate 722.

[0326] The gear bearing 730 is inserted into the bearing groove 722a and can rotate. The gear bearing 730 can have a central hole 732 formed at the center of rotation for the gear protrusion 726 to be inserted.

[0327] One side of the gear bearing 730 can contact the drive gear 720, and the other side can contact the bracket 740. The gear bearing 730 can be configured to rotate with the drive gear 720 in the area where it contacts the drive gear 720, and be fixed to the bracket 740 in the area where it contacts the bracket 740.

[0328] The bracket 740 is fixedly mounted on the rotating plate 500 and can support the drive shaft 714. The bracket 740 directly supports the drive shaft 714, or indirectly supports the drive shaft 714 through the drive gear 720 and the gear bearing 730.

[0329] Reference Figure 22 and Figure 23 The bracket 740 includes a fixed plate 746 fixed to the rotating plate 500 and a support plate 742 supporting the drive shaft 714. A pair of fixed plates 746 can be provided at both ends of the support plate 742. The fixed plates 746 can be used to secure the bracket 740 to the rotating plate 500 using additional fastening components (not shown). Therefore, when the rotating plate 500 rotates, the bracket 740 can also rotate together.

[0330] The support plate 742 can be configured between a pair of fixed plates 746. The support plate 742 forms a step at the portion where it connects with the fixed plates 746, which can create space for the drive gear 720 to be configured.

[0331] The support plate 742 includes: a bearing shaft support 744, which contacts the outer peripheral surface of the gear bearing 730 and supports the gear bearing 730; and a bearing plate support 745, which is disposed at the lower part of the gear bearing 730 to prevent the gear bearing 730 from detaching from the outside. The bearing shaft support 744 protrudes from the support plate 742 toward the direction in which the drive gear 720 is disposed. The bearing shaft support 744 can support the drive shaft 714.

[0332] The bearing shaft support 744 can contact the outer peripheral surface of the gear bearing 730, thereby preventing the gear bearing 730 from moving. This prevents movement of the drive gear 720 and drive shaft 714 connected by the gear bearing 730.

[0333] The bearing plate support 745 is disposed on the lower side of the gear bearing 730 to prevent the gear bearing 730 from detaching from the bracket 740. The bearing plate support 745 may be configured to contact the lower surface of the gear bearing 730. The bearing plate support 745 is configured to be perpendicular to the bearing shaft support 744.

[0334] When the rotating plate 500 rotates due to the operation of the drive motor 710, the overall structure of the blower 1 can rotate. In addition, when the rotation direction of the rotating plate 500 changes due to the operation of the drive motor 710, the drive shaft 714 may twist because the inertial force of the overall load of the blower 1 is different from the direction of movement of the drive motor 710. However, the above problem can be solved by supporting the drive shaft 714 with the bracket 740.

[0335] The bearing shaft support 744 may include a plurality of bearing shaft supports 744 protruding from the support plate 742. The plurality of bearing shaft supports 744 may be arranged circumferentially spaced along the outer peripheral surface of the gear bearing 730.

[0336] While the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. It is obvious to those skilled in the art that various modifications and implementations can be made without departing from the spirit of the invention as claimed in the claims, and such modifications and implementations should not be understood separately from the technical concept or prospect of the present invention.
