[0036] The embodiments disclosed in this specification will now be described in detail with reference to the accompanying drawings, and the same or similar structural elements will be given the same reference numerals regardless of the drawing numbers, and repeated descriptions thereof will be omitted.

[0037] In describing the embodiments disclosed in this specification, if it is determined that a detailed description of related well-known technologies would obscure the spirit of the embodiments disclosed in this specification, a detailed description thereof will be omitted. Furthermore, the accompanying drawings are only for ease of understanding of the embodiments disclosed in this specification; the technical concepts disclosed in this specification are not limited by the drawings and should be understood to encompass all modifications, equivalents, and even substitutions included within the scope of the present invention.

[0038] Terms containing ordinal numbers, such as "first" and "second," can be used to describe multiple constituent elements, but the constituent elements are not limited by these terms. These terms are used only for the purpose of distinguishing one constituent element from others.

[0039] The directional markings shown in the accompanying drawings, such as U (upper), D (lower), Le (left), Ri (right), F (front), and R (rear), are for illustrative purposes only, and the technical concept of the present invention is not limited by these directional markings.

[0040] Reference Figure 1 The blower 1 can extend long in the vertical direction. The blower 1 can be equipped with a base 2, a lower body 3, and upper bodies 10 and 20.

[0041] The base 2 can form the bottom surface of the blower 1 and can be placed on the floor of an indoor space. The base 2 can be formed in the shape of a circular plate.

[0042] The lower body 3 can be disposed on the upper side of the base 2. The lower body 3 can form the lower side of the blower 1. The lower body 3 can be formed in a cylindrical shape. For example, the diameter of the lower body 3 can gradually decrease as it approaches the upper part from the lower part of the lower body 3. As another example, the diameter of the lower body 3 can remain constant in the vertical direction. The suction port 3a can be formed through the side of the lower body 3. For example, a plurality of suction ports 3a can be evenly arranged along the circumference of the lower body 3. Thus, air can flow from the outside to the inside of the blower 1 through the plurality of suction ports 3a.

[0043] The upper bodies 10 and 20 can be configured on the upper side of the lower body 3. The upper bodies 10 and 20 can provide flow paths that communicate with the internal space of the lower body 3.

[0044] Referring to the accompanying drawings, for example, the upper bodies 10 and 20 may be provided with a first upper body 10 and a second upper body 20 spaced apart from each other.

[0045] As another example, the upper bodies 10 and 20 can be a single upper body. In this case, the upper bodies 10 and 20 can extend long in the vertical direction from the upper side of the lower body 3, or they can be formed into a circular (elliptical) or track-shaped ring or open ring shape. The position of the single upper body 10 and 20 relative to the lower body 3 can be determined by considering the shape of the upper bodies 10 and 20, the position, shape, and number of slits formed on the surface of the upper bodies 10 and 20 as air vents.

[0046] For the sake of brevity, the following explanation will be based on the case where the main bodies 10 and 20 are provided with a first upper body 10 and a second upper body 20. Furthermore, the explanation can be applied to cases where the number of upper bodies 10 and 20 is two, as long as it is not limited to cases where the number of upper bodies 10 and 20 is two.

[0047] The first upper body 10 and the second upper body 20 can be disposed on the upper side of the lower body 3. The first upper body 10 and the second upper body 20 can form the upper side of the blower 1. The first upper body 10 and the second upper body 20 can extend long in the vertical direction and be spaced apart from each other in the horizontal direction. On the other hand, the first upper body 10 can be referred to as the first tower or the first nozzle tower, and the second upper body 20 can be referred to as the second tower or the second nozzle tower.

[0048] A gap S can be formed between the first upper body 10 and the second upper body 20, and can provide an airflow path. The gap S can be open in the front-to-back direction. Alternatively, the gap S can be referred to as a blowing space, valley, or channel.

[0049] The first upper body 10 may be separated from the second upper body 20 to the left. The first upper body 10 may extend elongated in the vertical direction. The first upper body 10 may include a first panel 12 forming the surface of the first upper body 10. The first panel 12 may include: a first inner panel 121 facing the gap S; and a first outer panel 122 facing the first inner panel 121.

[0050] The first inner panel 121 can protrude from the first upper body 10 in the direction toward the gap S, i.e., to the right. For example, the first inner panel 121 can extend long in the vertical direction. The first outer panel 122 can protrude from the first upper body 10 in the direction opposite to that toward the gap S, i.e., to the left. For example, the first outer panel 122 can extend at a predetermined angle (acute angle) relative to the vertical line extending in the vertical direction toward the gap S, i.e., to the right.

[0051] At this time, the curvature of the first outer panel 122 can be greater than the curvature of the first inner panel 121. Furthermore, the first outer panel 122 can intersect with the first inner panel 121 to form an edge. This edge can be formed by a first front end 10F and a first rear end 10R of the first upper body 10. For example, the first front end 10F can extend rearward at a predetermined angle (acute angle) relative to a vertical line extending in the vertical direction. Similarly, the first rear end 10R can extend forward at a predetermined angle (acute angle) relative to a vertical line extending in the vertical direction.

[0052] The second upper body 20 may be separated from the first upper body 10 to the right. The second upper body 20 may extend elongated in the vertical direction. The second upper body 20 may include a second panel 22 forming the surface of the second upper body 20. The second panel 22 may include: a second inner panel 221 facing the gap S; and a second outer panel 222 facing the second inner panel 221.

[0053] The second inner panel 221 can protrude from the second upper body 20 in the direction toward the gap S, i.e., to the left. For example, the second inner panel 221 can extend long in the vertical direction. The second outer panel 222 can protrude from the second upper body 20 in the direction opposite to that toward the gap S, i.e., to the right. For example, the second outer panel 222 can extend at a predetermined angle (acute angle) relative to the vertical line extending in the vertical direction toward the gap S, i.e., to the left.

[0054] At this time, the curvature of the second outer panel 222 can be greater than the curvature of the second inner panel 221. Furthermore, the second outer panel 222 can intersect with the first inner panel 221 to form an edge. This edge can be formed by the second front end 20F and the second rear end 20R of the second upper body 20. For example, the second front end 20F can extend rearward at a predetermined angle (acute angle) relative to a vertical line extending in the vertical direction. Similarly, the second rear end 20R can extend forward at a predetermined angle (acute angle) relative to a vertical line extending in the vertical direction.

[0055] On the other hand, the first upper body 10 and the second upper body 20 can be symmetrical from left to right with a gap S between them. Furthermore, the surfaces of the first outer panel 122 and the second outer panel 222 can be located on an imaginary curved surface extending along the surface of the lower body 3. In other words, the surfaces of the first outer panel 122 and the second outer panel 222 can be seamlessly connected to the surface of the lower body 3. Additionally, the top surface 121u of the first upper body 10 and the top surface 221u of the second upper body 20 can be horizontal surfaces. In this case, the blower 1 can be formed in an overall truncated cone shape. This reduces the risk of the blower 1 tipping over due to external impacts.

[0056] The groove 31 may be located between the first upper body 10 and the second upper body 20, and extend elongated in the front-rear direction. The groove 31 may be a downwardly recessed curved surface. The groove 31 may include: a first side 31a, connected to the lower side of the first inner panel 121; and a second side 31b, connected to the lower side of the second inner panel 221. The groove 31, together with the first inner panel 121 and the second inner panel 221, may define the boundary of the gap S. Alternatively, the groove 31 may be referred to as a connecting groove or a connecting surface.

[0057] Reference Figure 2 The lower body 3 can provide internal space for the filter 4, control unit 5, fan 6 and air guide 7, which will be described later.

[0058] The filter 4 can be detachably disposed within the interior space of the lower body 3. The filter 4 can be formed in a generally cylindrical shape. That is, the filter 4 can include a hole 4P formed through the filter 4 in a vertical direction. Indoor air can be drawn in through the intake hole 3a (see reference 6) by the operation of the fan 6. Figure 1 The air flows into the interior of the lower body 3. Then, the indoor air flowing into the interior of the lower body 3 can be purified as it flows from the outer peripheral surface of the filter 4 to the inner peripheral surface, and flows to the upper side of the filter 4 through the hole 4P.

[0059] The control unit 5 can be installed inside the lower main body 3. The control unit 5 can be electrically connected to each component of the blower 1 and can control the operation of the blower 1.

[0060] The fan 6 can be disposed within the interior space of the lower body 3 and positioned above the filter 4. The fan 6 can generate a flow of air that flows into the interior of the blower 1 and then exits to the exterior of the blower 1. The fan 6 may include a fan housing 6a, a fan motor 6b, a hub 6c, a shield 6d, and moving blades 6e. Alternatively, the fan 6 can be referred to as a fan assembly or a fan module.

[0061] The fan housing 6a can form the appearance of the fan 6. The fan housing 6a can be formed in a generally cylindrical shape. A bell mouth can be located at the lower end of the fan housing 6a. An intake port (not marked) can be formed inside the bell mouth and supply air to the shroud 6d described later.

[0062] A fan motor 6b provides rotational force. The fan motor 6b can be a centrifugal fan motor or a mixed-flow fan motor. The fan motor 6b can be supported by a motor cover 7b (described later). In this case, the rotational shaft of the fan motor 6b can extend from the fan motor 6b towards its underside and can penetrate the bottom surface of the motor cover 7b. A hub 6c can be fixed to the rotational shaft and rotate with it. A shroud 6d can be spaced from the hub 6c towards its outer side. A plurality of moving blades 6e can be disposed between the hub 6c and the shroud 6d.

[0063] Thus, when the fan motor 6b is driven, air can flow in through the intake port along the axial direction of the fan motor 6b and be expelled radially and upward toward the fan motor 6b.

[0064] The air guide 7 can be positioned above the fan 6, i.e., downstream of the fan 6, and can provide a flow path 7P for the airflow exhausted from the fan 6. For example, the flow path 7P can be an annular flow path. The air guide 7 can include a guide body 7a, a motor cover 7b, and a stationary blade 7c. Alternatively, the air guide 7 can be referred to as a diffuser.

[0065] The guide body 7a can form the appearance of the air guide 7. The motor cover 7b can be disposed in the center of the air guide 7. For example, the guide body 7a can be formed in a cylindrical shape. The motor cover 7b can be formed in a bowl shape. In this case, the aforementioned annular flow path 7P can be formed between the guide body 7a and the motor cover 7b. A plurality of stationary blades 7c can be disposed in the annular flow path 7P and spaced apart from each other along the circumferential direction of the guide body 7a. Each of the plurality of stationary blades 7c can extend from the outer surface of the motor cover 7b to the inner circumferential surface of the guide body 7a. Thus, the plurality of stationary blades 7c can direct the air supplied from the fan 6 to the flow path 7P toward the upper side of the air guide 7.

[0066] The distribution unit 8 can be configured between the air guide 7 and the upper bodies 10 and 20. The distribution unit 8 can provide a flow path 8P for the air passing through the air guide 7. The air passing through the air guide 7 can be distributed to the first upper body 10 and the second upper body 20 by the distribution unit 8. Alternatively, the distribution unit 8 can be referred to as a splitter, intermediate body, inner body, tower base, or nozzle tower base.

[0067] The first upper body 10 can provide a first flow path 10P for a portion of the air passing through the air guide 7 and the distribution unit 8. The first flow path 10P can be formed in the internal space of the first upper body 10. The second upper body 20 can provide a second flow path 20P for the remaining air in the air passing through the air guide 7 and the distribution unit 8. The second flow path 20P can be formed in the internal space of the second upper body 20. That is, the first flow path 10P and the second flow path 20P can communicate with the flow path 8P of the distribution unit 8 and the flow path 7P of the air guide 7.

[0068] Reference Figure 1 and Figure 3 In addition to the aforementioned first inner panel 121 and first outer panel 122, the first upper body 10 may also be provided with a first wall 11. The first wall 11 may be located between the first inner panel 121 and the first outer panel 122. That is, the first panel 12 may surround the first wall 11. The first wall 11 may include a first inner wall 111 facing the inner side of the first inner panel 121 and a first outer wall 112 facing the inner side of the first outer panel 122.

[0069] The first inner wall 111 can be detachably attached to the inner side of the first inner panel 121. The first outer wall 112 can be detachably attached to the inner side of the first outer panel 122. The first inner wall 111 and the first outer wall 112 can be joined together and can form a first flow path 10P. Furthermore, the first inner panel 121 can be joined or fixed to a groove body 30 provided with grooves 31.

[0070] Thus, the first panel 12 can form the surface of the first upper body 10, and the first wall 11 can provide a first flow path 10P for airflow.

[0071] In addition to the aforementioned second inner panel 221 and second outer panel 222, the second upper body 20 may also be provided with a second wall 21. The second wall 21 may be located between the second inner panel 221 and the second outer panel 222. That is, the second panel 22 may surround the second wall 21. The second wall 21 may include a second inner wall 211 facing the inner side of the second inner panel 221 and a second outer wall 212 facing the inner side of the second outer panel 222.

[0072] The second inner wall 211 can be detachably attached to the inner side of the second inner panel 221. The second outer wall 212 can be detachably attached to the inner side of the second outer panel 222. The second inner wall 211 and the second outer wall 212 can be joined together and can form a second flow path 20P. In addition, the second inner panel 221 can be joined or fixed to the groove body 30 provided with the groove 31.

[0073] Thus, the second panel 22 can form the surface of the second upper body 20, and the second wall 21 can provide a second flow path 20P for airflow.

[0074] Reference Figure 4 A first vane 16 may be disposed on the first flow path 10P. The first vane 16 may be coupled to the inner side of the first wall 11. For example, the first vane 16 may be located on the first inner wall 111 and the first outer wall 112 (see reference). Figure 3 Between the two, the right end of the first stationary blade 16 can be attached to or fixed to the inner surface of the first inner wall 111.

[0075] The first stationary blade 16 may be adjacent to the first slit 10SL of the first upper body 10, which will be described later. The first stationary blade 16 may be in an upwardly convex shape. The rear end of the first stationary blade 16 may be located above the front end of the first stationary blade 16. For example, the first stationary blade 16 may include a plurality of first stationary blades 16a, 16b, 16c spaced apart from each other in the vertical direction.

[0076] On the other hand, the second vane 26a can be provided in the second flow path 20P, and the aforementioned description of the first vane 16 can be applied in the same way (see...). Figure 5 ).

[0077] Thus, the first stationary blade 16 can smoothly guide the air rising in the first flow path 10P to the rear. The second stationary blade 26 can smoothly guide the air rising in the second flow path 20P to the rear.

[0078] Reference Figure 5 The first connecting member 13 may be located in the first flow path 10P and connected to the rear end of the first stationary blade 16.

[0079] The first connecting member 13 can extend rearward and to the left at an incline from the first inner wall 111. Furthermore, the first connecting member 13 can be adjacent to the first rear end 10R of the first upper body 10 and separated from the first outer wall 112. In this case, a portion of the first opening LO can be located between the first connecting member 13 and the first outer wall 112, and formed forward and to the right at an incline. Here, the first opening LO can communicate with the first flow path 10P. Alternatively, the first opening LO can be referred to as the first discharge port or the first outlet.

[0080] Therefore, the air flowing in the first flow path 10P can be guided to the rear by the first stationary blade 16 and flow into the inlet of the first opening LO.

[0081] The first slit 10SL may be adjacent to the first rear end 10R of the first upper body 10 and formed through the first inner panel 121. The first slit 10SL may be formed elongated along the first rear end 10R of the first upper body 10. The first slit 10SL may be the outlet of the first opening LO. Thus, the first slit 10SL may discharge air flowing in the first flow path 10P into the gap S. Alternatively, the first slit 10SL may be referred to as the first discharge hole.

[0082] The second connecting member 23 may be located in the second flow path 20P and connected to the rear end of the second stationary blade 26.

[0083] The second connecting member 23 can extend rearward and to the right at an incline from the second inner wall 211. Furthermore, the second connecting member 23 can be adjacent to the second rear end 20R of the second upper body 20 and separated from the second outer wall 212. In this case, a portion of the second opening RO can be located between the second connecting member 23 and the second outer wall 212, and formed forward and to the left at an incline. Here, the second opening RO can communicate with the second flow path 20P. Alternatively, the second opening RO can be referred to as a second discharge port or a second outlet.

[0084] Therefore, the air flowing in the second flow path 20P can be guided to the rear by the second stationary blade 26 and flow into the inlet of the second opening RO.

[0085] The second slit 20SL may be adjacent to the second rear end 20R of the second upper body 20 and formed through the second inner panel 221. The second slit 20SL may be formed elongated along the second rear end 20R of the second upper body 20. The second slit 20SL may be the outlet of the second opening RO. Thus, the second slit 20SL can discharge air flowing in the second flow path 20P into the gap S. On the other hand, the second slit 20SL may be referred to as the second discharge hole.

[0086] For example, the first connecting member 13 and the second connecting member 23 can be symmetrical, and the first slit 10SL and the second slit 20SL can face each other. In this case, the first opening LO can be tilted or bent in front of the second slit 20SL. The second opening RO can be tilted or bent in front of the first slit 10SL. On the other hand, the first slit 10SL and the second slit 20SL will not be affected by the blower 1 (refer to...). Figure 1 This is what users looking from the front and back see.

[0087] First slot 10H (refer to) Figure 1The first air vent 10H can be formed adjacent to the first front end 10F of the first upper body 10 and extends through the first inner panel 121. The first air vent 10H can be formed elongated along the first front end 10F. The first air vent 19 can be disposed in the first space 19S and extend elongated along the first air vent 10H. The first air vent 19 can have an arc-shaped cross-section. The first moving component (not shown) can be disposed in the first space 19S and move the first air vent 19 in the circumferential direction of the first air vent 19. Thus, the first air vent 19 can close the first air vent 10H and allow passage through the first air vent 10H.

[0088] Second slot 20H (refer to) Figure 1 The second damper 20H can be formed adjacent to the second front end 20F of the second upper body 20 and penetrates the second inner panel 221. The second damper 20H can be formed elongated along the second front end 20F. The second damper 29 can be disposed in the second space 29S and extend elongated along the second damper 20H. The second damper 29 can have an arc-shaped cross-section. The second moving component (not shown) can be disposed in the second space 29S and move the second damper 29 in the circumferential direction of the second damper 29. Thus, the second damper 29 can close the second damper 20H and allow passage through the second damper 20H.

[0089] For example, the second damper 29 can be symmetrical to the first damper 19. The second moving component can be symmetrical to the first moving component.

[0090] For example, the first or second moving component may be provided with a rack-and-pinion gear connection structure, a pulley-and-belt connection structure, or a connecting member connection structure, etc., capable of transmitting the rotational force of the electric motor to the first damper 19 or the second damper 29. As another example, the first or second moving component may be provided with a connecting structure, etc., capable of transmitting the driving force of the actuator to the first damper 19 or the second damper 29.

[0091] Alternatively, the aforementioned second slot 20H, second damper 29, and second moving assembly can be omitted. In this case, the first damper 19 can move towards or away from the second upper body 20. For example, the end of the first damper 19 in the first position may be adjacent to or side-by-side with the surface of the first inner panel 121 of the first upper body 10. For example, the end of the first damper 19 in the second position may be adjacent to or in contact with the second inner panel 221 of the second upper body 20. The first damper 19 can move between the first position and the second position.

[0092] Alternatively, the aforementioned first slot 10H, first damper 19, and first moving assembly can be omitted. In this case, the second damper 29 can move towards or away from the first upper body 10. For example, the end of the second damper 29 in the first position may be adjacent to or side-by-side with the surface of the second inner panel 221 of the second upper body 20. For example, the end of the second damper 29 in the second position may be adjacent to or in contact with the first inner panel 121 of the first upper body 10. The second damper 29 can move between the first position and the second position.

[0093] Reference Figure 5 and Figure 6 The second slit 20SL can expel air flowing in the second flow path 20P into the gap S. The second slit 20SL can be adjacent to the second rear end 20R of the second upper body 20 and is formed through the second inner panel 221. The second slit 20SL can extend elongatedly along the second rear end 20R. At this time, the second slit 20SL can be tilted forward at a predetermined angle (acute angle) relative to the vertical line V extending in the vertical direction.

[0094] For example, the second slit 20SL may be parallel to the second rear end 20R. As another example, the second slit 20SL may not be parallel to the second rear end 20R. In this case, the second slit 20SL may be tilted relative to the vertical line V at a first angle θ1 (e.g., 4 degrees), and the second rear end 20R may be tilted relative to the vertical line V at a second angle θ2 (e.g., 3 degrees) less than the first angle θ1.

[0095] On the other hand, the first slit 10SL and the second slit 20SL can face each other and be symmetrical in the left-right direction.

[0096] Reference Figure 7 The first inner panel 121 and the second inner panel 221 can face each other and form the left and right boundaries of the gap S. The gap between the first inner panel 121 and the second inner panel 221 can first decrease and then increase as it approaches the front from the rear. The gap can be the width of the gap S.

[0097] The first interval B1 can be the interval between the first front end 10F of the first upper body 10 and the second front end 20F of the second upper body 20. The second interval B2 can be the interval between the first rear end 10R of the first upper body 10 and the second rear end 20R of the second upper body 20. The second interval B2 can be the same as or different from the first interval B1. The reference interval B0 can be the smallest among the intervals between the first inner panel 121 and the second inner panel 221.

[0098] Reference Figure 7 and Figure 8In the first state of the blower 1, the end of the first damper 19 can be inserted into the first slot 10H or hidden, and the end of the second damper 29 can be inserted into the second slot 20H or hidden. In this case, the end of the first damper 19 can form a continuous surface with the surface of the first inner panel 121, and the end of the second damper 29 can form a continuous surface with the surface of the second inner panel 221. On the other hand, the end of the first damper 19 can be inserted into the first slot 10H or hidden, the second damper 29 can be omitted, and the second slot 20H can be blocked. Alternatively, the end of the second damper 29 can be inserted into the second slot 20H or hidden, the first damper 19 can be omitted, and the first slot 10H can be blocked.

[0099] Air can interact with fan 6 (see reference) Figure 2 The action of the air ejected from the first slit 10SL and the second slit 20SL into the gap S. Afterward, the air ejected into the gap S can flow forward along the surface of the first inner panel 121 and the surface of the second inner panel 221.

[0100] This airflow can create an airflow that causes the air around the upper body 10, 20 to flow into the gap S (entrainment) or move forward along the surface of the first outer panel 122 and the second outer panel 222.

[0101] Therefore, blower 1 can provide users with sufficient airflow.

[0102] Reference Figure 9 and Figure 10 In the second state of the blower 1, a portion of the first damper 19 can pass through the first slot 10H and be located in the gap S, and a portion of the second damper 29 can pass through the second slot 20H and be located in the gap S. In this case, the ends of the first damper 19 and the second damper 29 can abut or be adjacent to each other. Alternatively, a portion of the first damper 19 can pass through the first slot 10H and be located in the gap S, the second damper 29 can be omitted, and the second slot 20H can be blocked. Or, a portion of the second damper 29 can pass through the second slot 20H and be located in the gap S, the first damper 19 can be omitted, and the first slot 10H can be blocked.

[0103] Air can interact with fan 6 (see reference) Figure 2 The action of the air ) corresponds to the air being expelled from the first slit 10SL and the second slit 20SL into the gap S. Afterward, the air expelled into the gap S can flow forward along the surface of the first inner panel 121 and the surface of the second inner panel 221, and rises as it is blocked by the first damper 19 and the second damper 29.

[0104] Therefore, the blower 1 can provide an upward airflow and circulate the air in the indoor space where the blower 1 is installed.

[0105] Reference Figure 11 and Figure 12 The second damper 29 can extend long along the second groove 20H. The second damper 29 can be configured in a second space 29S (refer to) which is the space between the second wall 21 and the second panel 22. Figure 5 ), and it penetrates the second slot 20H.

[0106] The foregoing and subsequent descriptions of the second damper 29, the configuration for moving the second damper 29, and the configuration combined with the second damper 29 are equally applicable to the first damper 19 (see reference). Figure 5 The configuration for moving the first damper 19 and the configuration for engaging with the first damper 19.

[0107] Reference Figure 13 The length of the second damper 29 can be greater than the width of the second damper 29. For example, the length of the second damper 29 can be approximately 15 times greater than the width of the second damper 29.

[0108] The upper end 29U of the second damper 29 can be called the first short side, and the lower end 29D of the second damper 29 can be called the second short side. The front end 29F of the second damper 29 can be called the first long side, and the rear end 29R of the second damper 29 can be called the second long side.

[0109] At this time, refer to Figure 9 and Figure 10 In the second state of the aforementioned blower 1, the front end 29F of the second damper 29 can contact the front end of the first damper 19.

[0110] The upper holder 296 may be adjacent to the upper end 29U and the rear end 29R of the second damper 29 and is fixed to the inner surface of the second damper 29. The lower holder 297 may be adjacent to the lower end 29D and the rear end 29R of the second damper 29 and is fixed to the inner surface of the second damper 29.

[0111] Reference Figure 14 The upper retainer 296 may include an upper fixing part 2960, an upper rack 2961, an upper horizontal rib 2962, and an upper vertical rib 2963.

[0112] Upper fixing holes 2960a and 2960b can be formed by passing through the upper fixing part 2960. Fastening components such as screws can pass through the upper fixing holes 2960a and 2960b and be fastened to the second damper 29 (see reference). Figure 13 The inner surface of ).

[0113] The upper rack 2961 can be formed on the inner surface of the upper fixing part 2960. The upper rack 2961 can be located between the first upper fixing hole 2960a and the second upper fixing hole 2960b. The upper rack 2961 can be positioned according to the second damper 29 (see reference). Figure 5 The curvature of the curve is bent.

[0114] The upper horizontal rib 2962 can protrude horizontally from the inner surface of the upper fixing part 2960. The upper horizontal rib 2962 can be located on the upper side of the upper rack 2961.

[0115] The upper vertical rib 2963 can extend upward from the end of the upper horizontal rib 2962. The upper vertical rib 2963 can be bent according to the curvature of the upper rack 2961.

[0116] Reference Figure 14 and Figure 15 The upper guide 294 may include a first upper guide 294a and a second upper guide 294b.

[0117] The mounting portion 294a1 of the first upper guide 294a can be located in the second space 29S (refer to...). Figure 5 ) Fixed to the outer surface of the second wall 21 (refer to Figure 17 For example, an upper guide groove (not shown) may be formed on the bottom surface of the first upper guide 294a and guide the movement of the upper vertical rib 2963.

[0118] The second upper guide 294b may be opposite to the first upper guide 294a relative to the upper vertical rib 2963. The second upper guide 294b may be detachably coupled to the first upper guide 294a. For example, an upper guide rib 294c may be formed on the top surface of the second upper guide 294b and guide the movement of the upper vertical rib 2963. In this case, the upper guide rib 294c may be bent according to the curvature of the upper vertical rib 2963. In addition, the second upper guide 294b may include a plate 294d supporting the bottom surface of the upper horizontal rib 2962.

[0119] On the other hand, the first shaft retainer 294e can protrude downward from the bottom surface of the second upper guide 294b. The first hole 294ea can be formed inside the first shaft retainer 294e.

[0120] Reference Figure 16 and Figure 17The motor 298 can be engaged with the second upper guide 294b on the lower side of the second upper guide 294b. For example, the first engagement portions 294b1 and 294b2 can be formed on one side of the second upper guide 294b, and the second engagement portions 298b1 and 298b2 can be formed on one side of the motor 298. In this case, the second engagement portions 298b1 and 298b2 can be fastened to the first engagement portions 294b1 and 294b2.

[0121] Furthermore, the rotating shaft 298a of the motor 298 can protrude from the top surface of the motor 298 towards the second upper guide 294b. The drive gear 292b can be fixed to the rotating shaft 298a. The first pinion 292a can mesh with the drive gear 292b and is fixed to the outer circumferential surface of the shaft 291S adjacent to the upper end of the shaft 291S. Additionally, the first pinion 292a can mesh with the upper rack 2961 (see reference). Figure 14 Engagement. Here, shaft 291S can extend long along the second damper 29. The upper end of shaft 291S can be inserted into the first hole 294ea (see reference). Figure 15 It can be rotatably coupled to the first shaft retainer 294e (see reference). Figure 15 ).

[0122] In this case, the length axis of the second damper 29, the length axis of shaft 291S, the rotation center axis of the first pinion 292a, the rotation center axis of the drive gear 292b, and the rotation axis 298a can be parallel to each other. For example, the length axis of shaft 291S can be inclined at a specified angle θ (acute angle) relative to the vertical line VL. Angle θ can be perpendicular to the vertical line VL and the second groove 20H (see reference). Figure 1 The angles between them are essentially the same.

[0123] Reference Figure 18 The lower retainer 297 may include a lower fixing part 2970, a lower rack 2971, a lower horizontal rib 2972, and a lower vertical rib 2973.

[0124] The lower fixing holes 2970a and 2970b are formed by passing through the lower fixing part 2970. Fastening components such as screws can pass through the lower fixing holes 2970a and 2970b and be fastened to the second damper 29 (see reference). Figure 13 The inner surface of ).

[0125] The lower rack 2971 can be formed on the inner surface of the lower fixing portion 2970. The lower rack 2971 can be located between the first lower fixing hole 2970a and the second lower fixing hole 2970b. The lower rack 2971 can be positioned according to the second damper 29 (see reference). Figure 5 The curvature of the curve is bent.

[0126] The lower horizontal rib 2972 ​​can protrude horizontally from the inner surface of the lower fixing part 2970. The lower horizontal rib 2972 ​​can be located on the lower side of the lower rack 2971.

[0127] The lower vertical rib 2973 can extend downward from the lower end of the lower fixing part 2970 and intersect with the lower horizontal rib 2972. The lower vertical rib 2973 can be bent according to the curvature of the rack 2971.

[0128] Reference Figure 18 and Figure 19 The lower guide 295 can be engaged with the lower retainer 297 on the lower side of the lower retainer 297.

[0129] The mounting part 295a of the lower guide 295 can be installed in the second space 29S (see reference). Figure 5 ) Fixed to the outer surface of the second wall 21 (refer to Figure 20 For example, a lower guide groove 295c can be formed on the top surface of the lower guide member 295 and guide the movement of the lower vertical rib 2973. In this case, the lower guide groove 295c can be bent according to the curvature of the lower vertical rib 2973. Additionally, a portion of the lower guide member 295 can support the bottom surface of the lower horizontal rib 2972.

[0130] On the other hand, the second shaft retainer 295d can protrude upward from the top surface of the lower guide 295. The second hole 295da can be formed inside the second shaft retainer 295d.

[0131] Reference Figure 19 and Figure 20 The lower end of shaft 291S can be inserted into the second hole 295da and rotatably engaged with the second shaft retainer 295d. The second pinion 293 can be fixed to the outer circumferential surface of shaft 291S adjacent to the lower end of shaft 291S. Furthermore, the second pinion 293 can mesh with the lower rack 2971.

[0132] In this case, the rotation center axis of the second pinion 293 can be coaxial with the length direction axis of the shaft 291S.

[0133] Therefore, in motor 298 (refer to) Figure 17 When driven, the second damper 29 can be in the first state of the blower (refer to...) Figure 7 Figure 8 ) and second state (refer to) Figure 9 and Figure 10 The first damper 19 can also move between the two states. Similarly, the first damper 19 can also be in the first state of the blower (see reference). Figure 7 and Figure 8 ) and second state (refer to) Figure 9 and Figure 10 Move between ).

[0134] Reference Figure 21 and Figure 22 The second air door 29 may include upper protrusions 29a and 29b (upper boss) and lower protrusions 29c and 29d (lower boss).

[0135] The upper protrusions 29a and 29b may be adjacent to the upper end 29U and the rear end 29R of the second damper 29, and may be formed on the inner surface and / or outer surface of the second damper 29. The first upper protrusion 29a may be connected to the first upper fixing hole 2960a of the upper fixing portion 2960 (see reference). Figure 14 Alignment. The second upper protrusion 29b can be aligned with the second upper fixing hole 2960b of the upper fixing part 2960 (see reference). Figure 14 Alignment. That is, fastening components such as screws can pass through the upper fixing holes 2960a and 2960b (refer to...). Figure 14 They are fastened to the upper protrusions 29a and 29b.

[0136] The lower protrusions 29c and 29d may be adjacent to the lower end 29D and the rear end 29R of the second damper 29, and may be formed on the inner and / or outer surface of the second damper 29. The first lower protrusion 29c may be connected to the first lower fixing hole 2970a of the lower fixing portion 2970 (see reference). Figure 18 Alignment. The second lower protrusion 29d can be aligned with the second lower fixing hole 2970b of the lower fixing part 2970 (refer to...). Figure 18 Alignment. That is, fastening components such as screws can pass through the lower fixing holes 2970a and 2970b (refer to...). Figure 18 They are fastened to the lower protrusions 29c and 29d.

[0137] The bar 299 may extend elongatedly along the rear end 29R of the second damper 29. The bar 299 may be attached to the rear end 29R of the second damper 29. For example, the second damper 29 may be made of resin. For example, the bar 299 may be made of a metal such as iron (Fe) or aluminum (Al). Thus, the bar 299 can improve the rigidity of the second damper 29.

[0138] The portion of the second damper 29 corresponding to the upper protrusions 29a and 29b can pass through the upper retainer 296 (see reference). Figure 13 To improve rigidity, the portion of the second damper 29 corresponding to the lower protrusions 29c and 29d can be secured by the lower retainer 297 (see reference). Figure 13 This can be used to improve rigidity. In this case, the upper end of strip 299 can be adjacent to the upper protrusions 29a and 29b, and the lower end of strip 299 can be adjacent to the lower protrusions 29c and 29d. That is, the portion of the second damper 29 located between the upper protrusions 29a and 29b and the lower protrusions 29c and 29d can have its rigidity improved by strip 299.

[0139] Therefore, the overall rigidity of the second damper 29 can be improved. On the other hand, the strip 299 can be referred to as an edge cover, strip, or reinforcement part.

[0140] Refer again Figure 3 and Figure 21 The first outer wall 112 may include a first base wall 1121 and a first mounting wall 1122. The first base wall 1121 may face the first inner wall 111 and form the boundary of the first flow path 10P. The first mounting wall 1122 may extend upward from the first base wall 1121 and is adjacent to the upper retainer 196.

[0141] In this case, the upper end of the strip 199 fixed to the rear end 19R of the first damper 19 can be located on the upper side of the first base wall 1121 (see reference). Figure 21 (d11). Thus, strip 199 can not only strengthen the portion of the first damper 19 corresponding to the first flow path 10P (i.e., located from the first slit 10SL (refer to d11)). Figure 4 (The part of the airflow path that is expelled and passes through the gap S) can also strengthen the rigidity of other parts of the first damper 19.

[0142] On the other hand, the foregoing can also be applied to the second damper 29 and the associated strip 299. Alternatively, one pair of the second damper 29 and strip 299 and the first damper 19 and strip 199 can be omitted.

[0143] Reference Figure 23 and Figure 24 The second damper 29 can be bent. The radius of curvature r20 of the outer surface 292 of the second damper 29 can be greater than the radius of curvature r10 of the inner surface 291 of the second damper 29. That is, the curvature of the outer surface 292 of the second damper 29 can be less than the curvature of the inner surface 291 of the second damper 29.

[0144] Strip 299 may be elastic. Strip 299 may include a first portion 299a, a second portion 299b, and a third portion 299d. The first portion 299a may face the rear end 29R of the second damper 29. The second portion 299b may bend from the first portion 299a and face the outer surface 292 of the second damper 29. The third portion 299d may bend from the first portion 299a and face the inner surface 291 of the second damper 29. That is, a portion of the second damper 29 may be located between the second portion 299b and the third portion 299d.

[0145] Furthermore, the length of the second portion 299b relative to the first portion 299a can be longer by a predetermined length d30 than the length of the third portion 299d relative to the first portion 299a. That is, in the thickness direction of the second damper 29, a portion of the second portion 299b can overlap with the third portion 299d.

[0146] The protrusion 29t can protrude from the outer surface 292 of the second damper 29 toward the second portion 299b and is adjacent to the rear end 29R of the second damper 29. The protrusion 29t can extend elongatedly along the length direction of the second damper 29. The protrusion 29t can be integrally formed with the second damper 29. The protrusion 29t may include an inclined portion 29t1, a horizontal portion 29t2, and a vertical portion 29t3. The inclined portion 29t1 can be formed relative to the boundary between the protrusion 29t and the second damper 29 (see reference). Figure 24 The dashed line is inclined. The horizontal portion 29t2 can be connected to the inclined portion 29t1 and is parallel to the boundary. The vertical portion 29t3 can be connected to the horizontal portion 29t2 and is perpendicular to the boundary.

[0147] The engaging portion 299c can protrude from the end of the second part 299b toward the second damper 29. During the engagement of the second damper 29 with the strip 299, the engaging portion 299c can slide on the inclined portion 29t1 and the horizontal portion 29t2 and then engage with the vertical portion 29t3, and the third part 299d can contact the inner surface 291 of the second damper 29. During the separation of the second damper 29 and the strip 299, the strip 299 can open, and the engaging portion 299c can disengage from the constraint of the vertical portion 29t3.

[0148] Thus, strip 299 can be detachably attached to the second damper 29. For example, the end of the engaging portion 299c can be formed to be curved. In this case, the engaging portion 299c can smoothly engage and disengage from the protrusion 29t.

[0149] The rigid portion 299e can be formed by applying pressure from the inner surface of the third portion 299d outwards. A first gap g10 can be formed between the inner surface 291 of the second damper 29 and the rigid portion 299e. The rigid portion 299e can increase the rigidity of the strip 299, thereby increasing the rigidity of the second damper 29. Alternatively, according to an embodiment, in addition to the rigid portion 299e, the strip 299 may also be additionally provided with rigid portions formed on the first portion 299a, the second portion 299b, and / or the third portion 299d.

[0150] Reference Figure 25A second gap g20 can be formed between the outer surface 292 and the second portion 299b of the second damper 29. An inner protrusion 299f can protrude from the inner surface of the second portion 299b toward the outer surface 292 of the second damper 29 and is located in the second gap g20. The end of the inner protrusion 299f can contact the outer surface 292 of the second damper 29 and improve the rigidity of the second damper 29.

[0151] For example, the inner protrusion 299f may extend long along the protrusion 29t. As another example, the inner protrusion 299f may include a plurality of inner protrusions spaced apart from each other in the length direction of the protrusion 29t.

[0152] Reference Figure 22 and Figure 26 Pins 29g can be formed on the outer surface 292 of the second damper 29. For example, pins 29g can include a plurality of pins 29g1, 29g2, 29g3 spaced apart from each other along the length of the second damper 29. In this case, protrusions 29t can include a plurality of protrusions spaced apart from each other across pins 29g. A second portion 299b can cover pins 29g. Pins 29g can be referred to as gates.

[0153] Reference Figure 27 The guide protrusion 299g can protrude from the inner surface of the second part 299b to the third part 299d and is located on the upper end of the protrusion 29t.

[0154] Therefore, the guide protrusion 299g can guide the strip 299 to be attached to the second damper 29. That is, the user can attach the strip 299 to the second damper 29 while the guide protrusion 299g is in contact with the upper end of the protrusion 29t.

[0155] Reference Figures 1 to 27 The blower includes: a fan that generates airflow; a lower body that provides an internal space for housing the fan and has an intake port; a first upper body located above the lower body and communicating with the internal space of the lower body, having a side with a first exhaust port; a first damper extending through the side of the first upper body and movably coupled to the first upper body, having one end facing the outside of the first upper body and another end opposite to the one end; and a first strip extending along the other end of the first damper and coupled to the other end of the first damper.

[0156] The blower may further include: a second upper body located above the lower body and communicating with the internal space of the lower body, having a side with a second discharge hole formed thereon; and a gap formed between the side of the first upper body and the side of the second upper body, wherein the first damper is movable in a direction close to or away from the side of the second upper body.

[0158] The blower may further include: a second one extending along the other end of the second damper and engaging with the other end of the second damper.

[0159] The first damper and the second damper may be symmetrical to each other with respect to the gap.

[0160] The direction of movement of the first damper may be opposite to that of the second damper, and one end of the first damper may face the end of the second damper in the direction of movement of the first damper.

[0161] The first section may further include: a first portion facing the other end of the first damper; a second portion bending from one end of the first portion and facing the outer surface of the first damper; and a third portion bending from the other end of the first portion and facing the inner surface of the first damper; a portion of the first damper may be located between the second portion and the third portion.

[0162] The first damper may have an arc-shaped cross-section and be movable along the length of the arc. The first strip may be elastic and separably coupled to the first damper.

[0163] The radius of curvature of the outer surface of the first damper may be greater than the radius of curvature of the inner surface of the first damper. The first damper may also include a protrusion that protrudes from the outer surface of the first damper toward the second portion and is adjacent to the rear end of the first damper. The first damper may also include an engaging portion that protrudes from the end of the second portion toward the first damper and engages with the protrusion.

[0164] The protrusion may further include: an inclined portion formed to be inclined relative to the boundary between the protrusion and the first damper; a horizontal portion connected to the inclined portion and parallel to the boundary; and a vertical portion connected to the horizontal portion, perpendicular to the boundary, and engaging with the engaging portion.

[0165] The end of the engaging portion can be formed to be curved.

[0166] The first section may also include a guide protrusion that protrudes from the inner surface of the second portion toward the third portion and is located above the protrusion.
