The other end of the vane 134 located relatively lower than the one end of the vane 134 is opposite to the one end of the vane 134 located relatively lower. The position is the same as or lower than the one end, and the vane is positioned relatively higher. The position of the other end opposite to the one end may be the same as or higher than the one end.

[0093] As a result, the second vane 134 directs the air rising in the second flow passage 130p through the second slot. It can be smoothly guided to the 130s.

[0094] As shown in FIGS. 5 and 6, the damper 210 is mounted on the first upper body 120 and / or The damper 210 can be movably coupled to the second upper body 130. From the first upper body 120 and / or the second upper body 130 to the space 109 The damper 210 may be flat or curved. For example, the damper 210 can be an outwardly bulging plate. For example, the damper 210 includes a first damper 210a and a second damper 210b. It is possible.

[0095] The first damper 210a passes through the first slot 120h (see FIG. 7) and enters the space 1 09 or passes through the first slot 120h to the first upper body 120. The first damper 210a can be inserted into the first slot 120h. In addition, the air flowing through the first flow passage 120p leaks to the outside through the first slot 120h. Here, the first slot 120h is formed so that the first upper body 12 120f of the first upper body 120. The first slot 120h can be formed in the first upper body 120. The front end 120f of the casing 120 may be elongated along the front end 120f.

[0096] For example, the first slot 120h can be parallel to the front end 120f. For example, the first slot 120h is not parallel to the front end 120f, but is angled at a second angle relative to the vertical. The inclination of the first slot 120h can be greater than the inclination of the front end 120f. The first slot 120h can be referred to as the first board slit.

[0097] The second damper 210b passes through the second slot 130H (see FIG. 7) and enters the space 1 09 or passes through the second slot 130h to the second upper body 130. The second damper 210b can be inserted inside the second slot 130h. In addition, the air flowing through the second flow passage 130p leaks to the outside through the second slot 130h. Here, the second slot 130h is provided for the second upper body 13 130f of the second upper body 130. The second slot 130h can be formed in the second upper body 130. The front end 130f of the casing 130 may be elongated along the front end 130f.

[0098] For example, the second slot 130h can be parallel to the front end 130f. For example, the second slot 130h is not parallel to the front end 130f, but is angled at a first angle relative to the vertical. The inclination of the second slot 130h can be greater than the inclination of the front end 130f. The second slot 130h can be referred to as a second board slit.

[0099] The first slot 120h and the second slot 130h face each other and are The first damper 210a and the second damper 210b can be in contact with each other or spaced apart.

[0100] As a result, the first damper 210a and the second damper 210b are positioned in the space 109. In this case, the first damper 210a and the second damper 210b are located in the front part of the space 109. They may be at least partially covered or closed.

[0101] On the other hand, the damper 210 is passively operated by the user to move the first upper body 120 and / or The damper 210 can be moved relative to the second upper body 130. The blower 100 is automatically driven by a motor and a power transmission member 246 (see FIG. 12) provided inside the blower 100. The first upper body 120 and / or the second upper body 130 are moved relative to each other. It can be done.

[0103] The first boundary surface 121 of the first upper body 120 and the second boundary surface 122 of the second upper body 130 The two boundary surfaces 131 face each other and can form the left and right boundaries of the space 109. The first boundary surface 121 of the first upper body 120 bulges to the right, and the second upper body The second boundary surface 131 of the body 130 can bulge to the left. a first interface 121 of the upper body 120 and a second interface 122 of the second upper body 130; The distance between the 131 and the rear gets smaller and smaller as you go forward. Alternatively, the gap can be the width of the space 109.

[0104] The first distance B1 is the distance between the front end 120f of the first upper body 120 and the front end 120f of the second upper body 120. The second distance B2 can be defined as the distance between the front end 130f of the first The rear end 120r of the first upper body 120 and the rear end 120r of the second upper body 130 For example, the second interval B2 can be defined as the interval between the first interval B1 and The reference interval B0 may be the first interval of the first upper body 120. The gap between the first boundary surface 121 of the first upper body 130 and the second boundary surface 131 of the second upper body 130 For example, the reference interval B0 can be 20 to 30 mm. Cut.

[0105] For example, in the front-rear direction, the center of the first boundary surface 121 of the first upper body 120 and the center of the second boundary surface 121 of the first upper body 120 are The distance between the center of the second boundary surface 131 of the upper body 130 is the reference distance B0. In another example, the first boundary surface 12 of the first upper body 120 in the front-rear direction The portion of the second upper body 130 located forward of the center of the first upper body 130 and the second boundary surface 131 of the second upper body 130 The distance between the center and the portion located forward may be the reference distance B0. If the first upper body 120 is lowered, the rear of the center of the first boundary surface 121 of the first upper body 120 in the front-rear direction. and a portion located rearward of the center of the second boundary surface 131 of the second upper body 130. The distance between the placed parts may be a reference distance B0.

[0106] In this case, the width of the rear part of the space 109 is the second interval B2. The width of the central portion is the reference interval B0, and the width of the space 109 becomes The width of the front part of the space 109 can be as small as the first interval B1. The width of the space 109 can be increased from the center to the front. .

[0107] As a result, part of the air circulated by the fan 150 (see FIG. 4) passes through the first slit. The remaining part is discharged through the second slit 130s into the space 109. It is discharged into the space 109, where it can be mixed with air. Due to the coanda effect, the air discharged into the space 109 The first boundary surface 121 of the first upper body 120 and the second boundary surface 122 of the second upper body 130 It can flow forward along the interface 131.

[0109] As a result, the air discharged into the space 109 in response to the operation of the fan 150 (see FIG. 4) Air flows forward along the boundary surfaces 121, 131 of the upper bodies 120, 130. At this time, the air flowing forward flows along the curvature of the boundary surfaces 121 and 131. The air flow can be dispersed to the left and right. 0, 130 surrounding air is entrained into the space 109 or It is possible to form an airflow that moves forward along the surfaces 122 and 132. The device 100 can provide a user with a large volume of airflow.

[0110] As shown in FIGS. 10 and 11, when the fan 100 is in the second state, the first damper 210a A part of the damper 210 passes through the first slot 120h and is positioned in the space 109. A portion of b can pass through the second slot 130h and be positioned in the space 109. In this case, the front end 210f of the first damper 210a and the front end 210f of the second damper 210b and can abut against each other.

[0111] As a result, the air discharged into the space 109 in response to the operation of the fan 150 (see FIG. 4) Air flows forward along the boundary surfaces 121, 131 of the upper bodies 120, 130. The air is blocked by the first damper 210a and the second damper 210b along the way and rises upward. It is possible.

[0112] On the other hand, the length of the damper 210 protruding from the slot 120h or the length extending in the front-rear direction The position of the front end 210f of the damper 210 relative to the reference line LL' is adjusted to The direction of the air being expelled can be adjusted.

[0113] As shown in FIG. 12, the grill 173 is disposed between the filter 103 and the fan 150. The grill 173 prevents foreign matter from entering the inside of the fan 150. Once the filter 103 is separated from the lower body 110, the grill 173 can be This can prevent fingers from entering the inside of the fan 150.

[0114] As shown in FIGS. 13 to 15, the grill assembly 170 includes the grill 173, It can be equipped with a bell mouth (171) and a supporter 172. At this time, the bell mouth 171 and the supporter 172 are integrated into one body. They can be formed or provided separately and joined together.

In the air flow direction, the diameter of the suction port 170a becomes smaller from upstream to downstream. Air can smoothly flow into the fan 150 through the intake port 170a. The 171 is made of plastic or ABS resin (Acrylonitrile Butadiene Rubber). It may contain a (styrene) resin material.

[0116] The grooves (171a) are recessed from the lower surface of the bell mouth 171 to the upper side. The grooves are formed so as to be spaced apart from one another in the circumferential direction of the bell mouth 171. The 171a may be formed to be long in the front-rear direction.

[0117] The supporter 172 extends in the radial direction of the bell mouth 171 on the outer peripheral surface of the bell mouth 171. The support 110 may be connected or coupled to the inner circumferential surface of the lower body 110. The supporter 172 may be formed in a ring shape. For example, the supporter 172 may be Plastic or ABS resin (Acrylonitrile Butadiene S The material may include tyrene resin.

The number of the second wires 174 can be greater than the number of the second wires 175. A portion of the ear 175 is disposed on each end of the first wire 174, and the remainder is disposed on the first wire 175. 4.

[0121] The first wire 174 and the second wire 175 are connected to each other by welding or the like. In this case, the second wire 175 is connected to the upper side of the first wire 174. For example, the grill 173 may be connected or secured to the first wire 174. The first wire 174 may include a metal material. At this time, the diameter of a portion of the first wire 174 is set to the groove 17a. The width of the first wire 174 is larger than the width of the groove 171a, and a portion of the first wire 174 is coupled to the groove 171a in an interference fit manner. That is, the groove 171a can be formed to allow the first wire to pass through the bell mouth 171. It can guide the bonding of 174.

[0122] The leg 174a can be formed on a portion of the first wire 174. 4a is bent toward the inner part 172a at the end of the first wire 174. At this time, the length of the leg 174a is the inner length relative to the bell mouth 171. The height of the step of the part 172a can be substantially the same as that of the ring 174b. 174a and can be connected to the inner part 172a. The ring 174b is hung on a hook (not shown) provided on the lower side of the inner part 172a. In another example, a fastening member such as a screw can be used to fasten the collar 174b. The inner part 172a is fastened to a hole (not shown) formed on the lower side of the inner part 172a. On the other hand, the hook or the hole can be referred to as a fastening portion.

[0123] As a result, the lower end of the grille 173 inserted into the groove 171a is It can be positioned higher or at the same height as the lower end of the bell mouth 171.

The column 180 can be fastened to the column 180. 180 can be fixed to the base 102 .

[0143] As shown in FIGS. 17 and 18, the column 180 and at least one holder 1024 , can be positioned outside the entry or exit path of the filter 103 relative to the base 102. Here, the filter 103 moves from the upper side of the base 102 to the rear side, and It can be attached to the base 102 and moved forward to be separated from the base 102. The portion of the ram 180 that contacts the filter 103 is flush with the longitudinal axis of the filter 103. The columns can be arranged within a 180-degree range in the circumferential direction of the filter 103. For example, 80 can be positioned to the left, right, and rear of the filter 103.

[0144] The first column 181 is disposed at the rear portion of the upper surface 1022a of the upper body 1022.

The curvature of the first inner wall 1812 can be substantially the same as the curvature of the inner circumferential surface of the disk 110. The first inner wall faces the filter 103 and can contact the outer circumferential surface of the filter 103. The curvature of 1812 can be substantially the same as the curvature of the outer circumferential surface of filter 103 .

[0146] The second column 182 is disposed on the left side of the upper surface 1022a of the upper body 1022. The holder 1024 is provided on the left side of the upper surface of the upper body 1022. and can be combined into a second column 182. That is, the second column 182 is disposed on the left side of the filter 103 and fixed to the upper side of the base 102 via a holder 1024. At this time, the second column 182 is positioned along the outer circumferential surface of the filter 103. Specifically, the second column 182 can extend between a second outer wall 1821 and a second and an inner wall 1822.

[0147] The second outer wall 1821 is joined to the second inner wall 1822 on the left side of the second inner wall 1822. The second outer wall 1821 faces the lower body 110 and is The curvature of the second outer wall 1821 may be adjacent to or in contact with the inner circumferential surface of the lower body. The curvature of the inner circumferential surface of the second inner wall 1822 can be substantially the same as that of the inner circumferential surface of the first inner wall 1822. A part of the second inner wall 1822 contacts the outer circumferential surface of the filter 103. In this case, the curvature of the part of the second inner wall 1822 can be adjusted to the outside of the filter 103. It can be substantially the same as the curvature of the peripheral surface.

[0148] The third column 183 is disposed on the right side of the upper surface 1022a of the upper body 1022. The holder 1024 is provided on the right side of the upper surface of the upper body 1022. and can be combined into the third column 183. That is, the third column 183 is disposed on the right side of the filter 103 and fixed to the upper side of the base 102 via a holder 1024.

The third inner wall 1832 may have a curvature substantially identical to that of the inner circumferential surface of the filter 110. A part of the third inner wall 1832 contacts the outer circumferential surface of the filter 103. In this case, the curvature of the part of the third inner wall 1832 can be adjusted to the outside of the filter 103. It can be substantially the same as the curvature of the peripheral surface.

[0150] This allows the filter 103 to be rear-ended between the second column 182 and the third column 183. In this case, the first column 181 can be moved to the side and mounted on the base 102. The first column 182 and the third column 183 support the outer circumferential surface of the filter 103. That is, the column 180 can absorb the vibration generated by the fan 150 (see FIG. 16). The column 180 can minimize vibration of the filter 103 due to movement or the like. 2 to minimize the positional variation of the filter 103 relative to the filter 103. Increased dynamic resistance or reduced filtration efficiency can be minimized.

[0151] On the other hand, the control unit (not shown) is disposed in the internal space (not shown) of the upper part 1022. The control unit is electrically connected to the components of the fan 100 to control the fan. The operation of the blower 100 can be controlled by a cable (not shown). can be connected to provide power and signals.

[0152] In this case, the cable is placed inside the column 180, and the cable and filter In other words, the interference between the filter 103 and the base 102 can be prevented. During assembly or disassembly, the filter 103 or the cable may be damaged by contact with each other. The filter 103 is connected to the base 102 by the cable. For example, the cable can be attached to the first column 181. can be placed inside the

[0153] The first partition wall 1813 is disposed between the first outer wall 1811 and the first inner wall 1812. The first partition wall 1813 is located inside the first inner wall 1812 and between the first outer wall 1811 and the first inner wall 1812. The first partition wall 1813 can extend toward the first outer wall 1811 and the first inner wall 1812. The space between the wall 1812 can be divided into two or more sub-spaces. The column 181 may be formed long in the longitudinal direction.

[0154] For example, the first partition 1813 includes a first middle partition 1813a, a first left partition 1813b, a b, and a first right partition wall 1813c. a can be disposed at the center of the first column 181. The first left partition 1813b can be disposed between the first intermediate partition wall 1813a and the left frame of the first column 181. The first right partition wall 1813c is connected to the right of the first intermediate partition wall 1813a and the first column 181. The first intermediate partition wall 1813a, the first left partition wall 1813b, and the second left partition wall 1813c can be disposed between the side frames. The partition wall 1813b and the first right partition wall 1813c are connected to the first outer wall 1811 and the first inner wall 1812. The space between the power supply and the power cable can be divided into four sub-spaces. The signal cables are placed in two of the four sub-spaces. It can be arranged in a subspace.

[0155] The first intermediate partition wall 1813a is located inside the first inner wall 1812 and is connected to the first outer wall 181. 1 and can contact the inside of the first outer wall 1811. The wall 1813b extends toward the first outer wall 1811 inside the first inner wall 1812. The first right partition wall 1813c can be spaced apart from the inside of the outer wall 1811. The wall 1812 extends toward the first outer wall 1811 from the inside of the wall 1812 and is spaced apart from the inside of the first outer wall 1811. It can be done in a while.

[0156] The thickness of the first intermediate partition wall 1813a is the same as that of the first left partition wall 1813b. The thickness of the boss 1813d can be larger than that of the right partition wall 1813c. The first outer wall 1811 and the first inner wall 1812 are disposed inside the intermediate partition wall 1813a. It can guide the bonding of

[0157] As shown in FIGS. 18 and 19, a portion of the second inner wall 1822 of the second column 182 is Although the filter 103 is in contact with the outer peripheral surface thereof, the remaining portion is spaced apart from the filter 103. This can be done.

[0158] The support section L1 is a part of the second inner wall 1822 and extends in an arc. The support section L1 is connected to the rear end 182b of the second column 182, and the filter In other words, the curvature of the support section L1 is The curvature of the outer peripheral surface of the groove 03 can be substantially the same as that of the groove 03.

[0159] The approach section L2 is the remaining part of the second inner wall 1822 and extends in a straight line. The approach section L2 is connected to the front end 182a of the second column 182 and includes a filter 1. 03. That is, the approach section L2 is in front of the support section L1. can be placed in

[0160] The thickness of the second column 182 at the position of the support section L1 is The thickness of the rear end 182b of the second column 182 can be greater than the thickness of the rear end 182b of the second column 182. The thickness of the front end 182a of the second column 182 can be approximately twice or more. The thickness of the rear end 182b of the second column 182 is 10 mm, and the thickness of the front end The thickness of 182a can be 4 mm. This allows the filter 103 to be It is easy to enter the L2 area.

[0161] The third column 183 and the second column 182 can be symmetrical to each other. Each of the second column 182 and the third column 183 generally forms a wedge. For example, the approach section L2 of the second column 182 and the approach section L3 of the third column 183 can be formed in the shape of a The distance between the approach section of Ram 183 can increase from the rear to the front. As another example, in the front-rear direction, the approach section L2 of the second column 182 and the approach section L3 of the third column The spacing between the approach sections of 183 can be constant.

[0162] In addition, a virtual straight line P extending along the boundary between the approach section L2 and the support section L1 is The straight line P can intersect with the first central axis Ob. Here, the first central axis Ob is a longitudinal axis of the base 102 and a longitudinal axis of the lower body 110. The first central axis Ob can be coaxial with the direction axis. It can be coaxial with the central axis of rotation of the fan 150.

[0163] That is, the front end 182a of the second column 182 and the front end 183a of the third column 183 The first interval P1 is the interval between the rear end 182b of the second column 182 and the rear end 182b of the third column The distance P2 between the first end 183b and the rear end 183b of the first The spacing P1 can be equal to or greater than the outer diameter of the filter 103. The spacing P2 between the two can be smaller than the outer diameter of the filter 103.

[0164] The inner radius F1 of the filter 103 is the distance from the second central axis Of to the inner surface of the filter 103. The outer radius F2 of the filter 103 is the distance from the second central axis Of to the outer edge of the filter 103. Here, the second central axis Of can be the distance to the side of the filter 103. In this case, the thickness t of the filter 103 is the distance from the outer radius F2 to the inner radius F3. On the other hand, the second column 182 and the third column 183 may be The left side of an imaginary line that intersects the first central axis Ob and the second central axis Of and extends in the front-to-rear direction It can be mirrored to the right.

[0165] As shown in FIGS. 20 to 22, the first central axis Ob and the second central axis Of are spaced apart from each other. The second central axis Of is aligned with the first central axis Ob in the front-to-rear direction, and the first In other words, the second central axis Of can be positioned in front of the first central axis Ob. 1 can be offset forward with respect to the central axis Ob of the base 102. This prevents interference from the column 180 during assembly and disassembly of the filter 103. The front-to-back width of the filter 103 can be greater than the left-to-right width of the filter 103 .

[0166] The distance G between the first central axis Ob and the second central axis Of in the front-rear direction is 3 to 7 mm. If the gap G is less than 3 mm, the diameter of the filter 103 can be increased sufficiently. If the gap G exceeds 7 mm, the filter 103 may be stuck to the inside of the lower body 110. It may not take up enough space.

[0167] Alternatively, the interval G may be set to 1.5 to 2 times the outer diameter of the filter 103 (i.e., twice the outer radius F2). If the gap G is less than 1.5% of the outer diameter of the filter 103, If the gap G is too large, it may be difficult to increase the diameter of the filter 103. If the outer diameter exceeds 3.5%, the filter 103 will not be able to fully fill the internal space of the lower body 110. It may not be occupyable.

[0168] As shown in FIGS. 18 and 23, the second central axis Of is inclined forward relative to the first central axis Ob. By making the filter 103 eccentric, the volume of the filter 103 can be maximized. The distance between the first inner wall 1812 of the column 180 can be F3.

[0169] As shown in FIG. 23, the second central axis Of′, which is the longitudinal axis of the filter 103′, is aligned with the first The filter 103' is coaxial with the central axis Ob of the filter 103, and is supported by a first column 181. And the outer radius of the filter 103' can be the same as F3. For example, the outer diameter of the filter 103' can be 190 mm.

[0170] As shown in FIG. 18, the second central axis Of is eccentric to the front of the first central axis Ob, The filter 103 includes a first column 181, a second column 182, and a third column 183. The outer radius of the filter 103 is F which is larger than F3. 2. Here, the difference between F2 and F3 is the difference between the second central axis Of and the first central axis O b. For example, the gap G is 5 mm, and the gap The outer diameter of the rotor 103 can be 200 mm.

[0171] This increases the outer diameter and thickness of the filter 103, improving the filtering efficiency. It can be improved.

[0172] Further referring to FIGS. 20 and 21, the bell mouth 171 is located on the upper side of the filter 103. In this case, the air flowing into the lower body 110 is filtered. The water flows from the outer peripheral surface 103b of the filter 103 to the inner peripheral surface 103a, and is purified. The air can flow into the intake port 170a of the air mouth 171 (see FIG. 13).

[0173] The inner end of the bell mouth 171 forms the boundary of the suction port 170a, and the bell mouth The first part 1711 of the intake port 170 (see FIG. 16) may be the end of the intake port 170. The diameter BD of a is smaller than the inner diameter of the filter 103 (i.e., twice the inner radius F1). Half the difference between the diameter BD of the suction port 170a and the inner diameter of the filter 103 is The distance G between the first central axis Ob and the second central axis Of can be larger than the distance G between the first central axis Ob and the second central axis Ob. The suction port 170a of the filter mouth 171 is located above the hole 103p of the filter 103. In other words, the entire area of the suction port 170a overlaps with the hole 103p in the vertical direction. It can be.

[0174] As a result, even if the second central axis Of is eccentric forward with respect to the first central axis Ob, the suction port The entire area of 170a is located above the hole 103p, and the air is guided from the filter 103 to the fan 150. This minimizes the air flow resistance towards the

[0175] The distance between the inner end of the bell mouth 171 and the outer end of the supporter 172 is The width Bw of the supporter 172 can be the width Bw of the assembly 170 (see FIG. 13). The side end is the outer part 172b of the supporter 172 (see FIG. 13). The thickness t of the filter 103 is smaller than the width Bw of the grill assembly 170. Half the difference between the thickness t of the filter 103 and the width Bw of the grill assembly 170 is It can be larger than the distance G between the second central axis Of and the first central axis Ob. The portion between the inner peripheral surface 103a and the outer peripheral surface 103b of the filter 103 is a bell mouth 171. and the outer end of the supporter 172. In other words, the distance between the inner circumferential surface 103a and the outer circumferential surface 103b of the filter 103 in the vertical direction is All parts are the part between the inner end of the bell mouth 171 and the outer end of the supporter 172. Can overlap.

[0176] This allows the filter to be inserted even if the second central axis Of is offset forward relative to the first central axis Ob. The inner peripheral surface 103a of the filter 103 is disposed outside the inner end of the bell mouth 171, and the filter 1 The outer peripheral surface 103b of the filter 103 is disposed inside the outer end of the supporter 172, and the filter 103 This minimizes the interference of air flow passing through the nozzle.
