Description

[0001] This application is a divisional application of the invention patent application filed on October 3, 2019, entitled "Blower" and with application number 201980066510.X. Technical Field

[0002] This application relates to blowers such as circulators. Background Technology

[0003] Previously, as a blower capable of swinging up and down, there was a known circulator with a structure in which the housing of the blower section was supported by two support legs (see Patent Document 1).

[0004] The circulator described in Patent Document 1 has the following structure: two support legs are erected in the base with a gap wider than the width of the air supply section, and the air supply fan is pivotally supported between the two support legs. Therefore, the width of the base section must be larger than that of the air supply section, making it difficult to achieve miniaturization of the device.

[0005] Therefore, a circulator has been proposed in which a slit is provided in the housing of the air supply section, and a support foot provided in the base section is inserted into the slit, so that the air supply section is supported inside the housing by the support foot (see Patent Document 2).

[0006] If the structure is set like this, the looper can be designed compactly.

[0010] Patent Document 2: Japanese Patent No. 6363811 Summary of the Invention

[0011] The problem the invention aims to solve

[0012] However, although the circulator described in Patent Document 2 can be designed compactly, the movable area of ​​the up-and-down swing head is limited to an angle range from the horizontal direction to the upward tilting direction. Therefore, when the circulator is installed on a shelf or window frame, it cannot deliver air downwards beyond the horizontal direction.

[0013] Thus, the previous structure could not achieve a more downward (tilt) head movement than the horizontal direction while simultaneously pursuing a more compact device.

[0014] This application provides a blower that can deliver air downwards more than horizontally while pursuing a compact device.

[0016] According to one aspect of this application, a blower is provided, comprising: an air supply section having a housing having a slit extending in an upward and downward direction; and a support section having a support foot inserted into the slit and pivotally connected to the air supply section in a manner that allows the air supply section to rotate in an upward and downward direction. The air supply mechanism is configured such that, in a horizontal position where the air supply direction of the air supply section is horizontal, a gap is formed between the lower end of the slit and the support foot, so that the air supply section can rotate in a manner where the air supply direction of the air supply section is more downward than the horizontal direction.

[0017] According to another aspect of this application, a blower is provided, comprising: an air supply section having a housing having a slit extending in an upward and downward direction; a support section having a support foot that is inserted into the slit and pivotally connected to the air supply section in a manner that allows the air supply section to rotate in an upward and downward direction, the air supply section having a locking portion protruding in the direction of its rotation axis, the blower further comprising an angle adjustment mechanism, the angle adjustment mechanism comprising a plurality of locking recesses formed in the locking portion, a pressing pin received in the support foot, and a rebound portion that applies force by pressing the pressing pin against the locking recesses, the support foot having a slit formed in a manner that allows the locking portion to move, within which the pressing pin is pressed against one of the plurality of locking recesses.

[0018] According to another aspect of this application, a blower is provided, comprising: an air supply section having a housing having a slit extending in an upward and downward direction; a support section having a support leg that is inserted into the slit and pivotally connected to the air supply section in a manner that allows the air supply section to rotate in an upward and downward direction; a pivoting mechanism provided to suppress the disengagement of the pivot connection between the air supply section and the support leg; the pivoting mechanism having a locking portion protruding from the air supply section in a direction toward its rotation axis, a flange portion formed at the front end of the locking portion, a slit provided on the support leg and movably fitted with the flange portion, and a protrusion provided in the slit; the air supply mechanism is configured such that the protrusion and the flange portion rotate the support leg in a manner opposite to each other in the direction of the rotation axis, thereby suppressing the support leg from disengaging from the shaft portion of the air supply section.

However, it should be noted that the drawings are schematic, and the relationship between thickness and planar dimensions, the ratio of thicknesses of each layer, etc., differ from reality.

[0053] [summary]

[0054] By using the structure of the circulator that supports the air supply unit 2 inside the cover (housing) 20 with the support foot 33, it is possible to swing the head downwards more than in the horizontal direction.

[0055] [Appearance]

[0056] Figures 1 to 5 This is an external view showing the blower 1 of this application. Figure 1 It's a 3D image. Figure 2 This is the main view. Figure 3 It is the right view. Figure 4 It is a top view. Figure 5 This is a rear view. The blower 1 is constructed to enhance airflow through a spherical grid structure and appears compact through an evolved spherical shape design.

[0057] Specifically, such as Figures 1 to 5 As shown, the blower 1 of this application includes an air supply section 2 and a support section 3. The air supply section 2 has a grille 23 forming an air supply port 2a on the front side, and the support section 3 supports the air supply section 2.

[0058] Regarding the grille 23, multiple air guide vanes 24 are arranged in a vortex shape. The inner end portion 24b of the multiple air guide vanes 24, near the center O of the vortex, protrudes further in the airflow direction F than the outer end portion 24c connected to the air outlet 2a. In other words, relative to the outer end portion 24c of the portion 24a forming the multiple air guide vanes 24 within the grille 23, the inner end portion 24b protrudes in the airflow direction F. Furthermore, the portion 24a forming the multiple air guide vanes 24 refers to the portion of the grille 23 from which the cover 25 located at the center O of the vortex is removed. The inner end portion 24b refers to the inner end side near the center O of the vortex, including the vicinity of the inner end. The outer end portion 24c refers to the portion connected to the outer end side of the air outlet 2a. As a result, the air can be concentrated (converged) at the center, and the air velocity at the center in the airflow direction can be increased. In addition, the arrival distance of the air (spiral airflow) blown out from the air outlet 11 can be extended. As a result, the indoor air can be reliably agitated, the indoor temperature can be uniformized, and energy saving can be achieved. In addition, the air outlet 2a of the air supply section 2 is formed in a circular shape.

[0059] In the blower 1 of this application, the air supply section 2 is rotatably supported by the support section 3. That is, the blower 1 of this application includes the air supply section 2 and the support section 3 that rotatably supports the air supply section 2.

[0060] The air supply unit 2 preferably has a cover (housing) 20, which has a slit 210 extending in the upward and downward direction. Furthermore, the support unit 3 preferably has a support leg 33 that is inserted into the slit 210 and pivotally connected to the air supply unit 2 in a manner that allows it to rotate in the upward and downward direction. Thus, the air supply unit 2 can be supported inside the cover (housing) 20 by the support leg 33, and the air supply fan 1 can be made more compact.

[0061] At this time, the preferred configuration is that the air supply direction F of the air supply section 2 is in a horizontal position (in the horizontal direction). Figures 1 to 5 In the posture shown, a gap D1 is formed between the lower end 210a of the gap 210 and the support leg 33 (see reference). Figure 14 This allows the air supply unit 2 to rotate so that its air supply direction F is more downward than the horizontal direction. Therefore, it can supply air downwards more than the horizontal direction.

[0062] Thus, by making the blower 1 compact, it can be easily placed on a shelf or window frame. Furthermore, if it can deliver air downwards beyond the horizontal plane, it can deliver air downwards from the shelf or window frame when the blower 1 is placed on it. In other words, if the blower 1 of this application is used, it can be used not only when placed on the floor surface and delivering air upwards from the floor surface, but also when placed on a shelf or window frame and delivering air downwards from the shelf or window frame, thus increasing the flexibility of its installation location.

[0063] Furthermore, the preferred configuration ensures that the air outlet 2a of the air supply unit 2 is not blocked by the support part 3 when the air supply unit 2 is rotated to its maximum downward position up to the lower limit of its rotatable range. This prevents the airflow from the air outlet 2a from contacting the support part 3 when the air supply unit 2 is rotated to the lower limit of its rotatable range. As a result, airflow reduction is suppressed throughout the entire rotatable range of the air supply unit 2.

[0064] Furthermore, the cover (housing) preferably has an arc-shaped surface 20a centered on the rotation axis C of the air supply section 2. Also, the support section 3 preferably has a gap D2 of a predetermined size (see reference). Figure 15The concave curved surface 322a faces the arcuate surface 20a. Furthermore, it is preferably configured such that the gap D2 between the arcuate surface 20a of the cover (shell) 20 and the concave curved surface 322a of the support 3 does not increase when the air supply section 2 rotates. This suppresses interference between the air supply section 2 and the support 3 when the air supply section 2 rotates. Furthermore, it also suppresses the increase in the gap between the air supply section 2 and the support 3 when the air supply section 2 rotates. As a result, it prevents objects from being trapped in the gap between the air supply section 2 and the support 3 when the air supply section 2 rotates, thus improving safety.

[0065] Furthermore, it is preferable to form ribs 212 protruding in the width direction of the slit 210 on the inner surface 212c that divides the width of the slit 210 in the cover (shell) 20. This can improve the strength of the cover (shell) 20. In addition, by forming ribs 212 in the slit 210, it is possible to prevent hands or fingers from entering the slit 210, thereby improving safety.

[0066] Furthermore, it is preferable to provide a pivoting mechanism 50 that suppresses the release of the pivot connection between the air supply section 2 and the support foot 33. In this way, with the configuration that allows the air supply section 2 to be rotated manually, even if a torsional force is applied to the cover (housing) 20, the support foot 33 can be prevented from detaching from the air supply section 2.

[0067] Furthermore, the cover (housing) 20 preferably has a front cover 21 and a rear cover 22 that can be separated at a midpoint between the front and rear of the air supply section 2. This not only simplifies the manufacture of the front cover 21 and the rear cover 22, but also facilitates the placement of parts inside the cover (housing) 20. In other words, it improves the assembly performance of the air supply section 2. Moreover, it is preferable that the slit 210 is formed from the lower surface of the rear cover 22 through its back surface to its upper surface. Thus, since the slit 210 is formed in the rear cover 22 as a single component, positional displacement of the slit due to assembly errors, etc., can be suppressed. As a result, the air supply section 2 can rotate more smoothly.

[0068] Furthermore, it is preferable that the support foot 33 is located near the rear end of the support portion 3. In this way, even if the gap 210 is formed in the rear cover 22 which is separated from the front and rear of the air supply portion 2 at the middle position, the air supply portion 2 can be rotated in such a way that the air supply direction F of the air supply portion 2 is more downward than the horizontal direction.

[0069] [Details of each section]

[0070] The following uses Figures 6 to 9 The blower 1 of this application will be described in more detail here. Figure 6 This is an exploded 3D view of the blower. Figure 7 This is an exploded perspective view of the support components of the blower. Figure 8 This is an exploded perspective view of the support legs of the support unit. Figure 9 It is an exploded perspective view of the main body of the support unit.

[0071] (Air Supply Department)

[0072] like Figure 6 As shown, the air supply section 2 has a cover (shell) 20 with a slit 210 extending in the upward and downward direction. The cover (shell) 20 has a front cover 21 and a rear cover 22 that can be separated at the middle position between the front and rear of the air supply section 2.

[0073] In addition, the blower section 2 has a grille 23. Furthermore, the air supply section 2 has: a fan blade 27 for air supply, which generates airflow; an electric motor 28, which drives the fan blade 27; and an electric motor cover 29, which is installed on the rear cover 22 while holding the electric motor 28.

[0074] like Figure 6 As shown, the front cover 21 is formed into a cylindrical shape, resembling a cut-off portion of the front half of a spherical shell, and has a circular opening 21a at the front. The front cover 21 can be formed from a synthetic resin material such as polypropylene. Furthermore, a spherical grille 23 is inserted into the circular opening 21a from the rear.

[0075] The grille 23 is a front surface panel made of, for example, a highly impact-resistant synthetic resin material. In this application, the grille 23 has a plurality of vortex-shaped air guide vanes 24, which are formed in a convex-bending shape, gradually protruding towards the center O of the vortex. Therefore, if air is supplied from the rear of the grille 23 and the airflow (wind) passes through the grille 23 in the front-rear direction, a spiral airflow is generated that moves in a straight line while forming a vortex. In this application, the grille 23 is formed such that its front surface constitutes part of a sphere.

[0076] Thus, in this application, the front hemisphere of the air supply section 2 is formed by the front cover 21 and the grille 23.

[0077] On the other hand, the rear cover 22 is formed into a hemispherical shape by a plurality of spacers 22a, covering almost the entire surface of the rear cover 22, forming a plurality of vents 21 for introducing external gas. The rear cover 22 may also be formed of a synthetic resin material such as polypropylene.

[0078] Furthermore, a spherical shape is formed by the front cover 21 and the rear cover 22, in which the grille 23 is embedded. In other words, a spherical air supply section 2 is formed by the front cover 21 and the rear cover 22, in which the grille 23 is embedded.

[0079] Therefore, if the air supply section 2 is made spherical, it will have a refined appearance, and because it has no corners, it will have a more compact appearance. In addition, it can improve the cuteness and fashion sense of the appearance.

[0080] Alternatively, it can be configured to prevent fingers from entering through the gaps between the multiple air guides 24 while also reinforcing the grille 12, and to support the multiple air guides 24 by circular rings that intersect with each air guide 13.

[0081] Furthermore, in this application, a cylindrical wind tunnel section 26 extending rearward is provided at the outer periphery of the grille 23. This wind tunnel section 26 is a cylindrical component located radially outward of the fan blade 27, and its inner diameter is approximately equal to the inner diameter of the air outlet 2a. In other words, in this application, the portion of the grille 23 where the wind tunnel section 26 is located becomes the air outlet 2a of the air supply section 2 further inward. Thus, in this application, by providing a cylindrical wind tunnel section 26 inside the air supply section 2, the directional and straight-line propagation of the airflow, which functions specifically as an circulator, can be ensured.

[0082] The electric motor 28 drives the fan blade 27 and has an electric motor body 28a and an output shaft 28b protruding from the electric motor body 28a. The fan blade 27 is mounted at the front end of the output shaft 28b, and the fan blade 27 rotates about the output shaft 28b when the electric motor 28 is driven.

[0083] Furthermore, in this application, the motor 28 is held by the motor cover 29. Specifically, with the output shaft 28b inserted into the insertion hole 291 of the motor cover 29, the motor body 28a is held by the motor cover 29. The motor cover 29 is mounted on the rear cover 22 while holding the motor 28.

[0084] Furthermore, with the motor 28 and fan 27 mounted on the rear cover 22 via the motor cover 29, an air supply section 2 with an internally assembled air supply mechanism is formed by inserting the rear cover 22 into the front cover 21 in which the grille 23 is embedded.

[0085] By configuring the air supply section 2 in such a way that when the drive motor 28 rotates the fan blade 27, external air introduced from the vent 22b of the rear cover 22 is blown out from the air supply port 2a, and the air is delivered to the front of the air supply section 2. In addition, as described above, since the airflow (wind) from the rear to the front moves forward in a straight line while forming a vortex as it passes through the grille 23, the air blown out from the air supply port 2a generates a spiral airflow while moving forward.

[0086] Furthermore, in this application, the rear cover 22 has a vent 22c at the rear of the motor, and a vent 292 is formed in the motor cover 29.

[0087] Therefore, when the motor 28 drives the fan blades 27, external air is also introduced through the air vent 21a at the rear of the motor, thus ensuring a larger airflow. Furthermore, when the motor 28 drives the fan 27, an airflow is also generated through the air vent 292. Therefore, the airflow generated by the motor 28 itself can cool the motor 28 and serve as a heat dissipation countermeasure for the motor 28.

[0088] (Support section)

[0089] The support portion 3 is placed on a surface such as a floor, and a power cord 80 is installed on the support portion 3. Furthermore, as... Figure 7 As shown, the support 3 includes: a main body portion on which an air supply portion 2 is disposed; and a pair of support feet 33, which are fixed to the main body portion and support the air supply portion 2 inside the cover (housing) 20.

[0090] Preferably, the main body of the support portion 3 is substantially the same size as, or smaller than, the size of the air supply portion 2 when viewed from above. Thus, as... Figure 4 As shown, by making the size of the blower 1 approximately the same as the size of the air supply section 2 when viewed from above, it is possible to prevent the overall size of the blower 1 from becoming too large. Furthermore, if the main body of the support section 3 is made approximately the same size as the air supply section 2 when viewed from above, it is possible to prevent the blower 1 from tipping over while simultaneously miniaturizing it. In other words, it is possible to achieve miniaturization of the blower 1 while simultaneously providing more stable mounting.

[0091] In addition, such as Figure 8 As shown, a storage portion 333 is formed in the support foot 33, and the pressing pin 41 is stored in the storage portion 333 when it is inserted into the coil spring 42. Furthermore, by covering the storage portion 333, which houses the pressing pin 41 and the coil spring 42, with the fall-inhibiting cover 34, the pressing pin 41 and the coil spring 42 are prevented from falling out of the storage portion 333.

[0092] On the other hand, such as Figure 9 As shown, the main body of the support portion 3 has a lower base portion 31 that is circular in shape when viewed from above, and an upper base portion 32 that can be fitted into the lower base portion 31. The cover forming the outer surface of both the lower base portion 31 and the upper base portion 32 can be formed, for example, from a synthetic resin material such as polypropylene.

[0093] Furthermore, the main body of the support portion 3 is hollow inside, and the circuit board 35 and the left and right tilting mechanism 60 are housed in the hollow.

[0094] Furthermore, a foot-shaped support column 33 is vertically mounted further rearward than the center of the cover of the upper base 32, and an operation panel 323 is positioned further forward than the support column 33 of the cover of the upper base 32. Moreover, the air supply unit 2 is positioned above the upper surface 322 of the support column 321 with a gap (a gap D2 of a specified size in this application) formed between it and the upper surface 322.

[0095] Therefore, it is preferable that when the height of the support column 321 and the offset from the center of the support column 321 (the center of the upper part of the base when viewed from above) are set, a space is formed between the air supply section 2 and the operation panel 323 that does not obstruct the operation of the operation panel 323 by the user or others.

[0096] The control panel 323 includes, for example, a power button for switching the power supply on / off, an airflow button for adjusting the airflow of the air supply unit 2, and a oscillation button for switching the left and right oscillations on / off.

[0097] Furthermore, upward-opening openings 322b are formed on both sides of the upper surface 322 of the support portion 321 in the width direction. By inserting the front end (lower end) of the support leg 33 into these openings 322b, the support leg 33 is held within the main body of the support portion 3. In this application, the opening 322b is formed on the rear end side of the upper surface 322 of the support portion 321. That is, in this application, the support leg 33 is located near the rear end of the support portion 3.

[0098] Furthermore, in this application, the blower 1 includes a remote control 70 for switching the power on / off, etc., and a remote control mounting portion 324 for mounting the remote control 70 is formed at the lower rear end of the support column 321 (see reference). Figure 5 (etc.). In addition, a remote control receiver 35a is mounted on the circuit board 35 to receive signals from the remote control 70. The remote control receiver 35a protrudes forward from the lower end of the front side of the support column 321.

[0099] [Up and down head swing mechanism]

[0100] In this application, the air supply unit 2 is supported on the support unit 3 in a manner that allows it to swing up and down. Hereinafter, it will be used... Figures 10 to 17 To explain the up-and-down swing structure of the air supply unit 2. Additionally, Figure 10 This is a right view showing the maximum upward posture of the blower. Figure 11 This is a right view showing the maximum downward orientation of the blower. Figure 12 This is a perspective view showing the insertion state of the support legs of the blower into the gap. Additionally, Figure 13 It is a three-dimensional diagram showing a portion of the horizontal posture of the blower. Figure 14This is a right view showing a portion of the horizontal posture of the blower. Additionally, Figure 15 The right view shows a portion of the blower's maximum downward posture. Figure 16 The right view shows a portion of the maximum upward posture of the blower. Figure 17 This is a diagram showing the maximum downward posture of the blower of this application as observed along the air supply direction.

[0101] The blower 1 of this application enables the air supply section 2 to supply air from... Figure 10 The maximum upward pose shown Figure 11 The head swings up and down within the range of the maximum downward posture shown. That is, the blower 1 of this application can make the air supply unit 2 rotate in a manner in which the air supply direction F is not only more upward than the horizontal direction, but also more downward than the horizontal direction. Specifically, the air supply unit 2 can rotate within a range of -25° to +90° between the angle θ formed by the air supply direction F and the horizontal plane.

[0102] Herein, in this application, as Figure 12 As shown, the support foot 33 is pivotally connected to the motor cover 29 fixed to the rear cover 22 when it is inserted into the slot 210 formed in the rear cover 22 extending in the upward and downward direction.

[0103] Specifically, cylindrical shaft portions 293 are formed on both sides of the motor cover 29 in the width direction, protruding outward in the width direction. An insertion hole 332 for inserting the shaft portion 293 is formed at the front end of the cover (housing) 20 located inside the support foot 33.

[0104] Furthermore, by inserting the shaft portions 293 formed on both sides of the motor cover 29 in the width direction into the insertion holes 332 of the support feet 33, the motor cover 29 can be rotatably supported in the vertical direction while it is held by a pair of support feet 33.

[0105] Furthermore, the support foot 33 inserted into the gap 210 is held in the main body of the support portion 3 by inserting its lower end (the front end located on the outside of the housing) into the opening 322b formed on the upper surface 322 of the support portion 321.

[0106] Thus, with the lower end of the support foot 33 held in the main body of the support portion 3, the motor cover 29 is rotatably supported in the vertical direction by a pair of support feet 33, and the motor cover 29 is configured to rotate relative to the support portion 3 (the main body and the support foot 33).

[0107] At this time, the rear cover 22 with the motor cover 2 fixed thereon, the motor 28 and fan blade 27 fixed to the rear cover 22 via the motor cover 29, the front cover 21 embedded in the rear cover 22, the grille 23 embedded in the front cover 21 and the wind tunnel part 26 rotate with the rotation of the motor cover 29.

[0108] In other words, in this application, the air supply unit 2 is configured to rotate as a whole relative to the support 3 (main body and support 33) by rotating the motor cover 29 pivotally connected to a pair of support feet 33 relative to the support 3 (main body and support feet 33).

[0109] At this time, from the state where the support foot 33 is located at the lower end 210a side of the gap 210 to the state where it is located at the upper end 210b of the gap 210, the air supply part 2 rotates relative to the support part 3 (main body and support foot 33).

[0110] In this application, the air supply unit 2 is configured to rotate so that the air supply direction F of the air supply unit 2 is more downward than the horizontal direction.

[0111] Specifically, such as Figure 13 and Figure 14 As shown, when the air supply direction F of the air supply section 2 is in a horizontal position, a gap D1 is formed between the lower end 210a of the gap 210 and the support foot 33.

[0112] In this application, as described above, the support foot 33 is disposed near the rear end of the support portion 3. Specifically, the support foot 33 includes: a vertical portion 336, which, when held by the support portion 3, is erected upward from the opening 322b; an inclined portion 337, which is connected to the upper end of the vertical portion 336 and inclined forward and upward; and a pivot portion 338, which is connected to the front end of the inclined portion 337 and pivotally connected to the shaft portion 293. Furthermore, the aforementioned insertion hole 332 is formed in the pivot portion 338.

[0113] Furthermore, when the support foot 33 is held near the rear end of the support portion 3, a gap 210 exists in the middle of the vertical portion 336.

[0114] Furthermore, the cover (shell) 20 is configured to be divided into a front cover 21 and a rear cover 22 at a midpoint between the front and rear of the air supply section 2 in a horizontal position, and a gap 210 is formed near the lower edge of the rear cover 22 in the horizontal position. That is, the lower end 210a of the gap 210 is located near the center of the support section 3 in the front-rear direction in a horizontal position.

[0115] Thus, with the blower 1 in a horizontal position, a gap D1 is formed between the lower end surface 211a that divides the lower end 210a of the gap 210 and the front surface of the support foot 33.

[0116] Furthermore, in a horizontal position, by forming a gap D1 between the lower end face 211a and the front surface of the support foot 33, the air supply unit 2 can rotate further downward until the front surface of the support foot 33 contacts the lower end face 211a (see reference). Figure 15 In other words, the air supply unit 2 can be rotated so that the air supply direction F of the air supply unit 2 is more downward than the horizontal direction.

[0117] Furthermore, in this application, the slit 210 is formed up to near the upper edge of the horizontally positioned rear cover 22. That is, the slit 210 is formed from the lower surface of the rear cover 22 through the back surface to the upper surface. In other words, the slit 210 is formed from the lower surface of the rear cover 22 through the back surface to the upper surface.

[0118] Therefore, the air supply unit 2 can be rotated further upward until the rear surface of the support foot 33 contacts the upper end surface 211b that divides the upper end 210b of the gap 210 (see reference). Figure 16 ).

[0119] Thus, in this application, the air supply section 2 is configured to rotate in the up-down direction within a range from the state where the support foot 33 is located on the upper end 210b side of the gap 210 to the state where it is located on the lower end 210a side.

[0120] Furthermore, the air supply unit 2 is rotated until the front surface of the support foot 33 contacts the lower end face 211a of the gap 210. Figure 15 The state shown is the maximum downward posture of the blower 1 (the state where the blower 2 rotates to the lower limit of its rotatable range). As described above, in this application, the state in which the angle θ between the air supply direction F and the horizontal plane is -25° is the maximum downward posture.

[0121] Furthermore, the air supply unit 2 is rotated until the rear surface of the support foot 33 contacts the upper end face 211b of the gap 210. Figure 16 The state shown is the maximum upward posture of the blower 1 (the state where the blower 2 rotates to the upper limit of its rotatable range). As described above, in this application, the state in which the angle θ between the air supply direction F and the horizontal plane is ±90° is the maximum upward posture.

[0122] Furthermore, in this application, a pivot portion 338 is formed at the front end of the inclined portion 337 of the support leg 33, and this pivot portion 338 serves as the rotation axis C of the air supply portion 2 (see reference). Figures 14 to 16 ).

[0123] In addition, in this application, the rotation axis C of the air supply section 2 is aligned with the center of the spherical air supply section 2 when viewed from the side (in the state observed along the rotation axis direction).

[0124] Thus, if the rotation axis C of the air supply section 2 is aligned with the center of the air supply section 2, the outer surface of the cover (shell) 20 becomes an arc-shaped surface 20a centered on the rotation axis C of the air supply section 2. In other words, in this application, the cover (shell) 20 has an arc-shaped surface 20a centered on the rotation axis C of the air supply section 2.

[0125] Furthermore, with the air supply unit 2 supported on the support unit 3, a concave curved surface 322a is formed on the upper surface 322 of the support unit 321 facing the arc-shaped surface 20a. This concave curved surface 322a becomes part of a spherical surface concentric with the arc-shaped surface.

[0126] By forming an arc-shaped surface 20a and a concave curved surface 322a on the air supply section 2 and the support section 3, the concave curved surface 322a faces the arc-shaped surface 20a with a gap D2 of a predetermined size. Furthermore, the structure is configured such that when the air supply section 2 is rotated, the gap D2 between the arc-shaped surface 20a and the concave curved surface 322a of the support section 3 does not increase.

[0127] Therefore, when the air supply section 2 is rotated, interference between the air supply section 2 and the support section 3 can be suppressed. In addition, even when the air supply section 2 is rotated, the outline of the blower 1 (the outline shape of the blower 1 when viewed from the side) hardly changes.

[0128] Furthermore, if the gap D2 between the arc-shaped surface 20a and the concave curved surface 322a of the support portion 3 does not widen, it is possible to prevent objects from being trapped in the gap between the air supply portion 2 and the support portion 3 when the air supply portion 2 rotates, thereby improving safety.

[0129] In addition, the arc-shaped surface 20a can be formed at least in the part that faces the concave curved surface 322 when the air supply part 2 is rotated within the rotatable range, and it is not necessary to make the entire outer surface of the air supply part 2 an arc-shaped surface 20a.

[0130] Additionally, in this application, such as Figure 17 As shown, in the maximum downward posture where the air supply unit 2 rotates to the lower limit of its rotatable range, the air outlet 2a of the air supply unit 2 is not blocked by the support unit 3. That is, when the blower 1 is viewed along the air supply direction F, the lower end of the circular air outlet 2a is configured to be located at the same position as the upper front end of the support column 321, or at a position higher than the upper front end of the support column 321.

[0131] Thus, even when the blower 1 is set to its maximum downward position, the air discharged from the air outlet 2a can be prevented from contacting the support 3. In other words, the air discharged from the air outlet 2a can be prevented from being diffused by the support 3.

[0132] [Angle Adjustment Mechanism]

[0133] Furthermore, in this application, the blower 1 includes an angle adjustment mechanism 40, which, when the blower 2 rotates within its rotatable range, maintains the blower 2 at predetermined angles in stages. Hereinafter, [the following will be used] Figure 18 The angle adjustment mechanism 40 of this application will be described. Furthermore, Figure 18 This is a cross-sectional view showing the angle adjustment mechanism of the blower.

[0134] The angle adjustment mechanism 40 of this application includes: a pressing pin 41, which is abutted by the motor cover 29 to restrict the rotation of the motor cover 29; and a coil spring 42, which is inserted into the pressing pin 41 and applies force to the pressing pin 41 toward the motor cover 29.

[0135] As described above, the pressing pin 41 and the coil spring 42 are housed within the housing 333 of the support foot 33.

[0136] Furthermore, on both sides of the motor cover 29 in the width direction, arc-shaped locking portions 294 centered on the rotation axis C are formed in a manner that protrudes outward in the width direction. On the rotation axis C side of the locking portion 294, a plurality of locking recesses 294a are formed at predetermined intervals along the rotation direction. These plurality of locking recesses 294a correspond to the range of rotation (-25° to +90°) of the up and down swing head of the air supply unit 2.

[0137] Furthermore, with the support foot 33 holding the motor cover 29 in place, the front end of the pressing pin 41, which is housed in the storage portion 333, contacts the locking recess 294a. At this time, the coil spring 42 is housed in the storage portion 333 in a more contracted state than in the free state, and the pressing pin 41 applies force to the locking recess 294a side through the coil spring 42.

[0138] Therefore, when the user moves the air supply unit 2 in the up and down direction, the pressing pin 41 moves past the locking recess 294a with a click sound. Furthermore, if the user stops rotating the air supply unit 2 while the pressing pin 41 is in contact with one of the locking recesses 294a, the pressing pin 41 can lock the pressing pin 41 into the locking recess 294a with appropriate strength because the locking recess 294a is pressed by the pressing pin 41.

[0139] Thus, the angle adjustment mechanism 40 of this application consists of a pressing pin 41, a coil spring 42, a storage portion 333 for storing the pressing pin 41 and the coil spring 42, and a plurality of locking recesses 294a pressed by the pressing pin 41. Furthermore, any one of the plurality of locking recesses 294a is locked by the pressing pin 41.

[0140] If such an angle adjustment mechanism 40 is provided, the angle of the air supply unit 2 (the angle of the air supply direction F relative to the horizontal direction) can be changed manually and in stages.

[0141] Additionally, a gap 334 is formed at the connection between the inclined portion 337 and the pivot portion 338. This gap 334 is used to prevent the locking portion 294 from interfering with the support foot 33 when the motor cover 29 rotates relative to the support portion 3. This gap 334 is also formed in an arc shape centered on the rotation axis C.

[0142] [Gap Reinforcement Structure]

[0143] Furthermore, in this application, it is possible to suppress the reduction in strength caused by the formation of a gap 210 from the lower surface to the upper surface of the rear cover 22. Hereinafter, using... Figures 19 to 21 To illustrate the reinforcing structure of the gap 210 in this application. Furthermore, Figure 19 This is a rear view showing the rear cover of the blower. Figure 20 It is a three-dimensional view showing the support legs of the blower. Figure 21 It is a cross-sectional view of the support feet of the blower inserted into the gap.

[0144] In this application, as Figure 19 As shown, a pair of slits 210 extending in the upward and downward directions are formed on both sides of the rear cover 22, which is formed by connecting multiple spacers 22a. Furthermore, in this application, each slit 210 is formed from the lower surface to the upper surface of the rear cover 22.

[0145] At this time, if a gap 210 is formed only from the lower surface to the upper surface of the rear cover 22, the strength of the rear cover 22 will be reduced, and the cover (shell) 20 may deform when the air supply part 2 is rotated.

[0146] Therefore, in this application, as Figure 19 and Figure 21 As shown, within the inner surface 211 of the dividing slit 210, a rib 212 protruding in the width direction of the dividing slit 210 is formed on the inner surface 212c of the dividing slit 210. In this application, the rib 212 is formed over approximately the entire range from the lower end to the upper end of the inner surface 211c of the dividing slit 210.

[0147] By providing ribs 212 like this, the strength of the periphery of the gap 210, which is a low-strength area, can be increased in the rear cover 22, and deformation of the cover (shell) 20 can be suppressed when the air supply unit 2 is rotated. In addition, the inner surface 211 dividing the gap 210 has a lower end surface 211a, an upper end surface 211b, and an inner surface 212c.

[0148] In addition, in this application, a recess 331 is formed at the location of the support leg 33 corresponding to the rib 212.

[0149] Thus, by forming a recess 331 at the location of the support foot 33 corresponding to the rib 212, the relatively thick support foot 33 can move in the gap 210 without interfering with the rib 212.

[0150] Therefore, it is possible to strengthen the cover 22 while suppressing the reduction in strength of the support foot 33.

[0151] Furthermore, when the air supply section 2 is rotated, the lower part of the recess 331 is positioned below the rib 212. Specifically, as shown... Figure 21 As shown, the lower inner surface of the recess 331 is made approximately parallel to the rib 212. In this way, when the cover (housing) 20 is subjected to excessive force, the relative movement between the cover (housing) 20 and the support foot 33 can be more reliably suppressed because the rib 212 is in contact with the lower part of the recess 331.

[0152] [Pivot Mechanism]

[0153] Furthermore, in this application, the blower 1 includes a pivoting mechanism 50, which can prevent the support leg 33 from disengaging from the blower 2 when the blower 2 is rotated. Hereinafter, using... Figure 22 and Figure 24 The pivot mechanism of this application will be explained below. Additionally, Figure 22 This is a perspective view showing the state before the shaft of the motor cover of the blower is inserted into the insertion hole of the support foot. Figure 23 This is a perspective view showing the state after the shaft of the motor cover of the blower is inserted into the insertion hole of the support foot. Furthermore, Figure 24 This is a cross-sectional view showing the pivoting mechanism of the blower.

[0154] In this application, a locking piece 293a protruding radially outward is formed at the axial front end of the shaft portion 293 of the motor cover 29. The locking piece 293a is formed in an arc shape at a portion of the axial front end of the shaft portion 293.

[0155] Furthermore, in the insertion hole 332 of the support foot 33, an arc-shaped protrusion 332a protruding inward is formed with a portion having a cut. Also, in the inner circumference of the insertion hole 332, the portion where the arc-shaped protrusion 332a is not formed becomes a cut portion 332b. This cut portion 332b has a degree to which the locking piece 293a can pass through when the support foot 33 moves axially relative to the motor cover 29.

[0156] Therefore, in this application, when installing the support foot 33 onto the motor cover 29, firstly, as Figure 22 As shown, with the locking piece 293a and the notch 332b facing each other, the insertion hole 332 is inserted into the shaft portion 293, thus becoming... Figure 23 The state shown.

[0157] Then, in Figure 23 After the state shown, move the motor cover 29 along... Figure 23 Rotate in the direction indicated by the middle arrow so that the arc-shaped protrusion 332a and the locking piece 293a face each other axially.

[0158] Thus, at least when the air supply unit 2 is rotated within its rotatable range, when the support leg 33 moves in the direction of disengaging from the motor cover 29, the arc-shaped protrusion 332a contacts the locking piece 293a, preventing the support leg 33 from disengaging from the motor cover 29 (see reference). Figure 23 ).

[0159] Furthermore, in this application, a flange portion 294b protruding radially outward is formed at the axial front end of the locking portion 294 formed in the motor cover 29. This flange portion 294b is formed on the entire arc-shaped locking portion 294.

[0160] Furthermore, when the air supply unit 2 is rotated, the flange portion 294b also moves within the gap 334 of the support foot 33. Additionally, a protrusion 334a is provided within the gap 334 of the support foot 33, and at least when the air supply unit 2 is rotated within its rotatable range, the protrusion 334a and the flange portion 294b face each other axially.

[0161] Therefore, at least when the air supply unit 2 is rotated within its rotatable range, when the support leg 33 moves in the direction of disengagement from the motor cover 29, the protrusion 334a contacts the flange portion 294b, thus preventing the support leg 33 from disengaging from the motor cover 29 (see reference). Figure 23 ).

[0162] Thus, in this application, the pivoting mechanism 50 is composed of an arc-shaped protrusion 332a, a locking piece 293a, a protrusion 334a, and a flange 294b.

[0163] [Left and right head tilting structure]

[0164] Furthermore, in this application, as described above, the blower 1 includes a left-right swinging mechanism 60, enabling the blower 1 to swing in the left-right direction. Hereinafter, using... Figure 25 and Figure 26 Let's explain the left and right head-swinging structure. Furthermore... Figure 25 This is a cross-sectional view showing the left and right tilting mechanism of the blower. Figure 26 This is an exploded 3D view of the blower from the rear side.

[0165] like Figure 25 As shown, the support portion 3 has an internal cavity, and a left-right oscillating mechanism 60 is housed within this cavity. This left-right oscillating mechanism 60 includes: a resin mounting plate 61 fixed to the upper part 32 of the base; a central shaft 62 integrally formed with the mounting plate 61 via insert molding; and a oscillating motor 63 fixed to the upper surface of the mounting plate 61. Furthermore, the left-right oscillating mechanism 60 includes a resin bearing component (sleeve) 64 inserted into the lower end of the central shaft 62. A locking pawl 64a is integrally formed on the inner circumference of the lower end of the bearing component 64. Additionally, a notch 62a is formed on the outer circumference of the lower end of the central shaft 62, and the locking pawl 64a is pressed into this notch 62a.

[0166] Furthermore, regarding the support portion 3, as described above, its interior is hollow, and a left-right tilting mechanism 60 is housed within this hollow (see reference). Figure 26 The left and right oscillating mechanism 60 includes: a fixed plate 61; and a motor 63 for oscillating (see reference). Figure 25 The eccentric cam 65 is fixed to the output shaft 63a of the oscillating motor 63; the fixed shaft 66 is fixed to the lower part 31 of the base; and the bow-shaped connecting rod 67 is pivotally connected at one end to the eccentric cam 65 and at the other end to the fixed shaft 66.

[0167] Additionally, the fixing plate 61 is fixed to the upper part 32 of the base, and the central shaft 62 is rotatably inserted into the bearing component 64. The motor 63 for the oscillating head (including an eccentric cam 65 fixed to the output shaft 63a) and the fixing shaft 66 are respectively located away from the central shaft 62.

[0168] Furthermore, a cylindrical bearing component 64 with a locking claw 64a formed on its lower inner circumference is inserted into a shaft insertion hole 69 that is opened in the lower part 31 of the base. A central shaft 62 is inserted into the bearing component 64. In addition, a notch 62a is formed on the lower outer circumference of the central shaft 62, and the locking claw 64a, which serves as a locking piece, is pressed into the notch 62a. Furthermore, the opening 31b on the lower surface of the lower part 31 of the base is covered by a bottom cover 68.

[0169] Furthermore, insert molding is performed on the upper ends of the fixing plate 61 and the central shaft 62, connecting the upper part 32 and the lower part 31 of the base via the central shaft 62, and fixing the bearing component 64 of the central shaft 62 to the lower part 31 of the base. At this time, the central shaft 62 is inserted into the shaft insertion hole 69 via the bearing component 64, thus eliminating the gap between the central shaft 62 and the shaft insertion hole 69, preventing wear of the shaft insertion hole 69 caused by the rotation of the central shaft 62 or the generation of noise caused thereby, and making the rotation of the upper part 32 of the base (air supply part 2) centered on the central shaft 62 smooth.

[0170] Furthermore, if the user presses the swing button on the control panel 323 to activate the left and right swing, the eccentric cam 65, which is fixed to the output shaft 63a of the motor 63 for swinging, rotates eccentrically, and one end of the connecting rod 67 pivotally connected to the eccentric cam 65 moves in a circular motion. At this time, the other end of the connecting rod 67 is pivotally connected to the fixed shaft 66 fixed to the lower part 31 of the base. Therefore, through this circular motion, the upper part 32 of the base and the air supply part 2 installed thereon rotate (swish) in the left and right directions with the central axis 62 as the center, according to the radius of the circular motion.

[0171] Thus, the blower 1 of this application is connected to the lower base 31 and the upper base 32, which is rotatably mounted on the lower base 31, via a central shaft 62. The blower 1 has an air supply section 2 mounted on the upper base 32. A bearing component 64 is inserted into the lower base 31, and the central shaft 62 is rotatably inserted into the bearing component 64. The fixing plate 61 mounted on the upper base 32 and the upper end of the central shaft 62 are fitted together. This ensures the strength of the connection while reducing the number of parts and lowering costs.

[0172] Additionally, a fixing plate 61, formed of resin, is provided on the upper part 32 of the base. This prevents damage to the wiring when it comes into frictional contact with the edge (corner) of the fixing plate 61.

[0173] Furthermore, a locking pawl 64a is integrally molded from resin on the lower inner circumference of the bearing component 64 of the central shaft 62. Thus, the locking pawl 64a functions in place of the E-ring, thereby reducing the number of parts and lowering costs by eliminating the need for an E-ring.

[0174] Additionally, the upper part 32 of the base (air supply part 2) slides on the track (travel path) R via a ball (rolling body) B installed on the upper part 32 of the base, and rotates (oscillates) in the left and right directions (refer to) Figure 9 ).

[0175] [Cable wiring structure]

[0176] Furthermore, in this application, the wiring of cable 91 is led out from the shaft portion 293 of the swing head. Hereinafter, it will be used... Figure 27 and Figure 28 This section will explain the cable wiring structure. Furthermore, Figure 27 It is a 3D diagram showing the wiring configuration of the cables provided by the blower. Figure 28 This is a three-dimensional view of the cable wiring configuration of the blower, viewed from the rear side.

[0177] In this application, as Figure 27 and Figure 28 As shown, the motor cover 29 is held from both sides by a pair of support feet 33 that stand up from the support part 3. The position of this holding is used as the rotation axis C of the up and down swinging head, and the air supply part 2 swings up and down relative to the support part 3.

[0178] Furthermore, the cylindrical shaft portion 293 formed in the motor cover 29 serves as the rotation axis C of the up and down swing head.

[0179] Therefore, in this application, the cable 91 connected to the motor 28 is led out from the shaft (shaft portion 293) of the up and down swing head, which is used to drive the fan blades 27 housed in the motor cover 29.

[0180] Furthermore, the cable 91, which is led out from the shaft (shaft portion 293) of the swing head, is pulled outward through the insertion hole 34a of the fall suppression cover 34 and is housed in the recess 335 formed in the support foot 33.

[0181] In addition, in this application, with the support foot 33 held in the main body of the support portion 3, the recess 335 communicates with the cavity in the main body of the support portion 3, so that the cable 91 is disposed in the recess 335 and led out from the communication portion to the cavity in the main body.

[0182] Additionally, in this application, such as Figure 27 As shown, a hook-shaped rib 61a protruding upward is formed on the upper part of the fixing plate 61, and the cable 91 leading out from the connecting part to the hole in the main body is hooked on the hook-shaped rib 61a.

[0183] Furthermore, the cable 91 is led out to the lower part of the fixing plate 61 in a state of being hooked on the hook rib 61a, and the front end of the cable 91 led out to the lower part of the fixing plate 61 is electrically connected to the connector 92 mounted on the circuit board 35.

[0184] At this time, as Figure 28 As shown, a downward protruding rib 61b is formed at the lower part of the fixed plate 61. This rib 61b can prevent the bent part of the cable 91 from contacting the linkage mechanism of the left and right swing head mechanism 60 and breaking the cable.

[0185] If the wiring of cable 91 is configured as described above, no torque will be applied to cable 91 when it swings up and down, thus more reliably preventing cable 91 from breaking.

[0186] [An example of usage]

[0187] Next, an example of using the aforementioned blower 1 will be explained. Furthermore, Figure 29 This is a perspective view showing an example of the operating state of the blower 1.

[0188] like Figure 29 As shown, the blower 1 of this application can be used, for example, mounted on a shelf 101 formed in a household toilet 100. Thus, when the blower 1 is mounted on the shelf 101, it is preferable to use the blower 2 in a state where the airflow direction F is rotated downwards more than the horizontal direction. This allows the airflow from the blower 1 to be directed towards the toilet bowl 102, which is located below the shelf 101.

[0189] Alternatively, the blower 1 of this application can be disposed, for example, on a shelf in a changing room, and blow air in a manner that is more downward than horizontal.

[0190] [Variation Example]

[0191] Furthermore, the blower is not limited to the configuration of blower 1 described above, and may also be configured as follows: Figure 30 The blower 1A is shown. Additionally... Figure 30 This is a perspective view showing a first modified example of the blower.

[0192] Regarding the blower 1A, as follows Figure 30 As shown, a switch 322A that is operated manually is formed. Specifically, Figure 30 The blower 1A shown is switched on / off by manually rotating switch 322A and the air volume of the air supply unit 2 is adjusted.

[0193] Furthermore, the blower 1A, like the blower 1 shown in the above embodiment, can be configured such that the air supply section 2 can rotate in a manner in which the air supply direction F of the air supply section 2 is more downward than the horizontal direction.

[0194] Alternatively, the blower can be set as follows: Figure 31 The blower 1B is shown. Additionally... Figure 31 This is a perspective view showing a second modified example of the blower.

[0195] like Figure 31As shown, the blower 1B is a circulator with a planar grille structure. That is, a planar grille 23 is provided in the air supply section 2, which has a generally drum-shaped shape, and a circular air supply port 2a that opens at the front.

Claims

1. A blower, comprising: An air supply unit having a housing having a slit extending in a vertical direction; The support portion has a support foot that is inserted into the gap and is pivotally connected to the air supply portion in a manner that allows the air supply portion to rotate about a rotation axis in an up-down direction. The air supply unit is provided with a locking part that protrudes in the direction of its rotation axis; The blower also includes an angle adjustment mechanism, which consists of a plurality of locking recesses formed in the locking portion, a pressing pin housed in the support foot, and an elastic component for applying force to the pressing pin toward the locking recesses. The support foot has a gap for the locking part to move within it, and the pressing pin is pressed into one of the plurality of locking recesses by the action of the elastic member.

2. A blower, comprising: An air supply unit having a housing having a slit extending in a vertical direction; The support portion has a support foot that is inserted into the gap and is pivotally connected to the air supply portion in a manner that allows the air supply portion to rotate about a rotation axis in an up-down direction. A pivoting mechanism is provided to prevent the pivoting state between the air supply unit and the support leg from being released. The pivoting mechanism includes: a locking portion protruding from the air supply portion toward its rotation axis, a flange portion formed at the front end of the locking portion, a gap formed in the support foot and allowing the flange portion to move therein, and a protrusion provided in the gap. When the air supply section rotates, the protrusion and the flange face each other in the direction of the rotation axis, thereby restricting the axial movement of the support foot and preventing the support foot from disengaging from the shaft of the air supply section.
