Description

[Technical Field]

[0001] The present invention relates to a blower such as a circulator. [Background technology]

[0002] Conventionally, a known blower device is an electric fan that includes a fan section (corresponding to the blower section of the present invention), a base section that is placed on the floor, and a frame section that has a pair of arms that are rotatably attached to the left and right sides of the fan section and are supported so that they can swing freely on the left and right sides of the base section, and that can take a free-standing position in which the arms rise up from the base section to lift the fan section, or a folded position in which the arms and base section are parallel and the overall shape is flat (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3191871 Publication Summary of the Invention [Problem to be solved by the invention]

[0004] However, with this type of fan, the fan and base are aligned side by side when folded, requiring a large amount of space for storage. Furthermore, when trying to direct the airflow upward, the frame gets in the way, limiting the airflow direction.

[0005] The present invention aims to solve the above problems and provide a blower that can be folded more compactly, requires less space when stored, and can blow air in a wide range of directions. [Means for solving the problem]

[0006] The blower device described in claim 1 of the present invention comprises a front guard, a rear guard, a blower section consisting of a fan arranged in a space defined by the front guard and the rear guard, a motor arranged on the rear side of the blower section and driving the fan, a motor section accommodating the motor, and a main body and support member supporting the blower section, wherein the motor section has a first connection section, the main body has a second connection section and a third connection section, the support member has a fourth connection section, the main body has a first grounding section, the support member has a second grounding section, a first swinging section which swingably connects the first connection section and the second connection section, and a second swinging section which swingably connects the third connection section and the fourth connection section, and the second swinging section is configured to ground the first grounding section and the second grounding section on the installation surface when the main body and the support member are opened at a predetermined angle by the second swinging section, thereby supporting the blower section.

[0007] The blower device according to claim 2 of the present invention is the same as claim 1, wherein the first oscillating portion is provided at the axial center of the main body, and the second oscillating portion is provided at both axial ends of the main body.

[0008] Furthermore, the blower device described in claim 3 of the present invention is the same as claim 1 or claim 2, in which the central axis of the first oscillating part and / or the central axis of the second oscillating part is positioned so as to intersect with the central axis of the motor part.

[0009] Furthermore, the cooking device according to claim 4 of the present invention is the cooking device according to claim 1, wherein an anti-slip member is attached to the first ground contact portion and / or the second ground contact portion. [Effects of the Invention]

[0010] The blower device described in the present invention is configured as described above, and the second swinging part opens the main body and the support member to a predetermined angle, and the first and second grounding parts contact the installation surface, thereby supporting the blower unit. The first swinging part also allows the blowing direction of the blower unit to be changed over a wide range. The second swinging part also allows the main body and the support member to be closed, and the first swinging part allows the blower unit to be moved to a stored position, allowing for space-saving storage.

[0011] Furthermore, by providing the first swinging portion at the axial center of the main body and the second swinging portion at both axial ends of the main body, the size of the first connecting portion can be reduced. Also, the width of the second grounding portion of the support member can be increased, so the blower unit can be supported more stably.

[0012] Furthermore, since the central axis of the first oscillating part and / or the central axis of the second oscillating part is located at a position that intersects with the central axis of the motor, when the air blowing direction is directed straight up, the center of gravity of the air blowing part is located approximately in the center between the first ground contact part and the second ground contact part, thereby providing more stable support.

[0013] Furthermore, by attaching an anti-slip member to the first ground contact portion and / or the second ground contact portion, the main body and the support member are less likely to slip on the floor surface, thereby more stably supporting the blower unit.

[Figure 7] FIG. [Figure 8] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. In the description of the embodiment, the lower left direction in Fig. 1 will be referred to as the front, the upper right direction as the rear, the lower right direction as the right, and the upper left direction as the left.

[0016] The blower of the present invention is designated by 1. This blower 1 is composed of a blower section 2, a motor section 3, a main body 4, and a support member 5.

[0017] The blower 2 is made up of a front guard 6, a rear guard 7, and a fan 8 disposed in a space defined by the front guard 6 and the rear guard 7. The outer periphery of the front guard 6 is a cylindrical ring portion 9. A lattice portion 10 made of metal wire is fixed to this ring portion 9. A decorative plate 11 is fixed to the center of the lattice portion 10. The front guard 6 has a cylindrical shape with a bottom and an open rear side. A fixing member 12 is attached to the underside of the ring portion 9 so as to be able to swing relative to the ring portion 9.

[0018] The rear guard 7 is composed of a lattice portion 13 made of metal wire and a handle 14 also made of metal wire. The handle 14 is fixed by welding or the like to the upper rear side of the rear guard 7. The lattice portion 13 has a cylindrical shape with a closed bottom and an open front side.

[0019] The front guard 6 and the rear guard 7 have a detachable structure. The front guard 6 and the rear guard 7 are fixed by engaging a hook provided on the ring portion 9 and a hook on the fixing member 12 with the lattice portion 13, respectively. Then, by rotating the fixing member 12, which is attached so as to be swingable relative to the ring portion 9, downward, the hook of the ring portion 9 is disengaged from the lattice portion 13. Then, by disengaging the hook provided on the ring portion 9 from the lattice portion 13, the front guard 6 can be detached from the rear guard 7. When the front guard 6 is attached to the rear guard 7, the central axis of the bottomed cylindrical shape of the front guard 6 and the central axis of the bottomed cylindrical shape of the rear guard 7 are on a center line X1. The motor unit 3 is disposed behind the rear guard 7. The motor unit 3 is a hollow cylinder that houses a motor (not shown) for driving the fan 8. The rear guard 7 and the motor unit 3 are fixed together with a fixing screw or the like. At this time, the central axis of the motor unit 3 and the central axis of the housed motor are aligned on the center line X1. The central axis of the cylindrical, bottomed shape of the rear guard 7 and the central axis of the motor unit 3 are also aligned on the center line X1.

[0020] The rotation shaft of the motor housed in the motor unit 3 protrudes along the center line X1 into the space defined by the front guard 6 and the rear guard 7.

[0021] The fan 8 is an axial flow fan that has a cylindrical hub at its center and multiple blades on the peripheral wall of the hub. The fan 8 is attached to the rotating shaft of the motor with mounting screws or the like. At this time, the central axis of the fan 8 and the rotating shaft of the motor are on the center line X1. That is, the central axis of the fan 8 and the central axis of the motor unit 3 are also on the center line X1.

[0022] In summary, the central axis of the motor unit 3, the central axis of the front guard 6, the central axis of the rear guard 7, and the central axis of the fan 8 are aligned on the center line X1.

[0023] Furthermore, because the central axes of the components constituting the blower unit 2 and the motor unit 3 are aligned on the center line X1 and because of the weight relationship between the components, the center of gravity when the blower unit 2 and the motor unit 3 are combined is near the connection point between the motor unit 3 and the rear guard 7 on the center line X1.

[0024] An operation unit 15 and a display unit 16 are provided above the motor unit 3. By pressing this operation unit 15, the blower 1 can be turned on and off, and by rotating it, the rotation speed of the fan 8 can be changed, and the air volume can be adjusted.

[0025] Furthermore, the display unit 16 uses LEDs arranged in the motor unit 3 that light up when the fan device 1 is in the ON state, and the number of lights that light up changes depending on the air volume. In this embodiment, one LED lights up when the air volume is minimum, and the number of lights increases as the air volume increases, until four lights up when the air volume is maximum. When the fan device 1 is in the OFF state, the LEDs are turned off.

[0026] A first connection part 17, which has a shape that is a combination of a semicircle and a square and extends in the left-right direction in a side view, is provided at the center of the rear of the motor part 3. This first connection part 17 has a recess 18 in its center and protrusions 19, 19 on both sides, so that it has a U-shape when viewed from a direction perpendicular to the center line X1 and a center line X2 (described later). In addition, an abutment part 26 is provided on the upper surface of the recess 18.

[0027] The main body 4 has a plate-like shape, and the upper and lower ends are semicircular when viewed from the side. A second connection portion 21 and third connection portions 22, 22 are provided on the upper side of the main body 4. The second connection portion 21 is provided in the center of the upper side of the main body 4, with recesses 20, 20 provided on the left and right sides thereof. The third connection portion 22 is provided near the left and right sides of the upper side of the main body 4. A DC jack (not shown) is attached to the left side of the main body 4, and power is supplied by connecting an AC adapter (not shown).

[0028] Then, the motor unit 3 and the main body 4 are connected together such that the second connection part 21 is inserted into the recess 18 of the first connection part 17, and at the same time, the convex parts 19, 19 of the first connection part 17 are inserted into the recesses 20, 20 of the main body 4.

[0029] The protrusions 19, 19 and the second connection portion 21 are connected using a torque hinge. This forms a first swinging portion 23 that swings the motor portion 3 and the main body 4. In this embodiment, the center point of the semicircle of the first connection portion 17 and the center point of the semicircle at the upper end of the main body 4 coincide when viewed from the side. If a line extending from these center points in the left-right direction is defined as center line X2, the central axis of the first swinging portion 23 is located on center line X2. In other words, the first swinging portion 23 is located in the center of the direction of center line X2. Furthermore, this center line X2 intersects with center line X1.

[0030] Since a torque hinge is used for the first swinging part 23, the angle between the motor part 3 and the main body 4 can be fixed at an angle desired by the user. In other words, the air blowing direction of the blower part 2 can be fixed at an angle desired by the user. In the case of this embodiment, the angle can be adjusted within a range from the angle at which the bottom surface 24 of the motor part 3 abuts against the front surface 25 of the main body 4 to the angle at which the abutment part 26 of the first connecting part 17 abuts against the protrusion 27 provided on the back side of the main body 4.

[0031] An anti-slip member 28 is attached to the underside of the main body 4. This anti-slip member 28 is made of an elastic material such as silicone, and acts as a non-slip member on the floor surface. The anti-slip member 28 is a first ground contact portion 29, which comes into contact with the installation surface F.

[0032] The fourth connection portion 30 of the support member 5 is attached to the third connection portion 22 of the main body 4. The support member 5 has the fourth connection portions 30, 30, connecting portions 31, 31, and leg portions 32. The support member 5 has a symmetrical shape, with the fourth connection portions 30, 30 connected to the leg portions 32 extending horizontally via the connecting portions 31, 31, which are slightly bent in a dogleg shape. In addition, an anti-slip member 33 is attached to the leg portions 32. Like the anti-slip member 28, the anti-slip member 33 is made of an elastic material such as silicone and acts as an anti-slip device on the floor surface. The anti-slip member 33 serves as a second grounding portion 34 and comes into contact with the installation surface F.

[0033] The third connecting portion 22 and the fourth connecting portion 30 are swingably connected by a swing mechanism provided in the third connecting portion 22. This forms second swinging portions 35, 35 that swingably move the support member 5 relative to the main body 4. The central axes of the second swinging portions 35, 35 are located on the center line X2. That is, the central axis of the first swinging portion 23 and the central axes of the second swinging portions 35, 35 are both located on the center line X2. The second swinging portions 35, 35 are located at both ends in the direction of the center line X2. In addition, a rotation prevention structure is provided inside the third connection part 22. As shown in Fig. 5, if the angle between the main body 4 and the upper side of the connecting part 31 is θ, in this embodiment, it is configured to swing within a range of θ = 0° to θ = 70°.

[0034] The second oscillating unit 35 may be configured to stop the angle θ at a desired angle by the user using a torque generating mechanism such as a torque hinge. Alternatively, the second oscillating unit 35 may not include a torque generating mechanism. In the former case, the user can freely determine the angle θ as long as the angle θ is such that the blower unit 2 can be supported when using the blower device 1, allowing use even in small installation spaces. In the latter case, the blower device 1 is used at the angle θ stopped by the aforementioned anti-rotation structure (70° in this embodiment). This angle is maintained by the weight of the blower unit 2 and the aforementioned anti-rotation structure, supporting the blower unit 2. Therefore, since the blower unit 2 can be supported without using a torque generating mechanism, the number of components in the second oscillating unit 35 can be reduced, thereby reducing manufacturing costs.

[0035] When storing the air blower 1, as shown in FIG. 7, the support member 5 is folded (the angle θ=0°) and the bottom surface 24 of the motor unit 3 and the front surface 25 of the main body 4 are placed parallel to each other. In other words, the main body 4 and the center line X1 are placed perpendicular to each other. This allows the air blower 1 to be stored by leaning it against the wall or laying it down in the space between pieces of furniture. It can also be stored in a small space such as a closet.

[0036] As described above, the central axis of the first oscillating portion 23 and the central axis of the second oscillating portion 35 are on the center line X2. The center line X2 is perpendicular to the center line X1.

[0037] Because of this positional relationship, when the air blowing direction of the air blowing unit 2 is directed straight up, the center of gravity of the air blowing unit 2 and the motor unit 3 combined is near the center between the first connection part 17 and the second grounding part 34, so the air blowing device 1 can be installed stably and the risk of it falling over can be reduced.

[0038] The present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the gist of the invention. For example, in the present embodiment, the central axes of the first swinging portion 23 and the second swinging portion 35 are both located on the center line X2, but the second swinging portion may be located near the center of the side surface of the main body 4 instead of on the center line X2.

[0039] Furthermore, although the first oscillating portion 23 is provided at the upper center of the main body 4 and the second oscillating portion 35 is provided on the upper left and right side surfaces of the main body 4, the first oscillating portion may be provided on the upper left and right side surfaces of the main body 4 and the second oscillating portion may be provided at the upper center of the main body 4.

[0040] Furthermore, anti-slip members 28, 33 are attached to the first ground contact portion 29 and the second ground contact portion 34, respectively, but an anti-slip member may be attached only to the first ground contact portion 29, or no anti-slip member may be used, and the leg portion 32 of the support member 5 may be used as the second ground contact portion, and a portion that serves as the first ground contact portion may be provided on the main body 4.

[0041] Furthermore, the protrusion 27 is provided on the main body 4 so that the air blowing direction of the air blowing unit 2 stops directly above, but it is also possible to direct the air blowing direction of the air blowing unit 2 toward the rear without providing a protrusion.
