Description

[Technical Field]

[0001] This invention relates to a small, portable wall fan that is easy to carry. [Background technology]

[0002] A conventional portable fan of this type is described, for example, in Utility Model Registration No. 3253221. This conventional portable fan includes an air duct provided inside an air duct housing, a motor base mounted on the axis of the air duct, and a peripheral wall of the motor base extending radially outward to form air guide vanes, each of which includes a parallel section and an inclined section, the parallel section being adjacent to the exhaust port and parallel to the axis of the exhaust port, the inclined section being adjacent to the air inlet, the inclined section being offset from the plane of the parallel section and having its extending surface intersecting the axial direction of the wind-driven vane group 5, and a wind-collecting cover covering the exhaust port. According to this device, the wind-driven vane group, the wind guide vanes, the pressure-boosting surface, and the wind-collecting cover work together to accelerate pressure buildup, eliminate turbulence, and reduce noise before being blown outward.

[0004] However, the conventional portable fans are only meant to be held in the hand and are not meant to be attached to a wall or placed on a desk, etc. In other words, the conventional portable fans are primarily designed to be used outdoors, not indoors, and are always meant to be held in the hand and cannot be placed in a desired location.

[0005] Furthermore, there are no openings on either side of the fan, and air intake is limited to the rear side, making it difficult to take in air if the fan is placed against a wall.

[0006] The present invention was made in consideration of the above points, and its purpose is to provide a portable wall-mounted fan that can be placed anywhere desired and easily carried when used indoors, especially in rooms where there is a nearby wall or a place to put the portable fan, such as a desk.The present invention also aims to provide a portable wall-mounted fan that can take in air well through the air intake section formed by the support member (spacer) formed on the side, even if the back of the fan, which is the main air intake, is in contact with the wall and the amount of air that can be taken in is limited.

DETAILED DESCRIPTION OF THE INVENTION

[0021] An embodiment of a portable wall-mounted fan according to the present invention will now be described with reference to the drawings. Figure 1 is a front view of the portable wall-mounted fan according to the present invention, Figure 2 is a rear view, Figure 3 is a side view, Figure 4 is a rear perspective view, and Figure 5 is an enlarged view of the connecting member that allows the fan housing to be raised and lowered.

[0022] 1 to 5, portable wall-mounted fan A comprises a case X in which a front panel 10 made of a thin, approximately rectangular plate and a back panel 11 of similar size and shape are fixed at a predetermined distance with spacers 12, 13 attached between the front panel 10 and the back panel 11, and a fan housing 20 housed within the case X. The fan housing 20 is made up of a substantially planar front guard 21 and a substantially hemispherical rear guard 22, and a motor (not shown) is housed in the center of the rear guard 22 and is connected to a fan 23.

[0023] Cylindrical spacers 12, 12 made of synthetic resin are attached to both ends of the upper portions of the front plate 10 and the rear plate 11 by fixing means such as screws, and a cubic box that houses a control member (not shown) for the fan 23, a storage battery (not shown), etc. is attached to the lower portions of the front plate 10 and the rear plate 11 as the spacer 13. A USB port 13a is provided on the side of the spacer 13.

[0024] The case X is formed, for example, with dimensions of about 200 mm in length and 150 mm in width, and a thickness of about 30 mm to 60 mm, but a thickness of about 45 mm is suitable for hanging on a wall W.

[0025] The front panel 10 has a storage hole 10a in its center that can store the fan housing 20, and a gripping recess 10b is formed at the upper edge of the storage hole 10a to allow the fan housing 20 to be gripped with fingers. Meanwhile, the back panel 11 has an open hole 11a of the same size as the storage hole 10a, which functions as an air intake when the portable wall-mounted fan A is used upright. Also, a hook hole 11b is formed at the top of the back panel 11 to receive a hook F, which will be described later.

[0026] A substantially cylindrical rotating connecting member 30 is provided on the lower part of the front panel 10 to support the fan housing body 20 so that it can rotate freely. The rotating connecting member 30 is formed by connecting a tip end (arm tip end) 32 of an arm 31 provided on the lower part of the fan housing body 20 to a rotating base 32 that rotates by itself so that the tip end 32 can rise and fall freely. The rotating base 33 is also connected to the spacer 13, and is formed so that the control member (not shown) and a motor (not shown) provided in the center of the rear guard body 22 are connected by a conductor 34.

[0027] FIG. 6 is a side perspective view showing the portable wall-mounted fan A hung on a wall, FIG. 7 is a perspective view showing the portable wall-mounted fan A with the fan storage section raised, and FIG. 8 is a perspective view showing the portable wall-mounted fan A hung on a wall with the fan storage section 20 raised and further rotated.

[0028] Because the portable wall-mounted fan A has the above-mentioned configuration, it is lightweight and compact, and can be installed and used by hanging the hook F from the storage hole 10a on the wall W of a room or a small space such as a toilet, as shown in Figures 6 to 8. Also, as shown in Figure 7, the fan housing 20 can be raised and the angle of the fan 23 can be set to a suitable position. Furthermore, as shown in Figure 8, the fan housing 20 can be rotated and the angle of the fan 23 can be set to a suitable position.

[0029] 6 to 8, when the portable wall-mounted fan A is hung on a wall W, the back panel 11 is in contact with the wall W, limiting the intake of air from the back, but a large air intake Y is formed on the side between the spacers 21, 12, and 13, allowing for adequate air intake even when hung on the wall W. The thickness of the portable wall-mounted fan A is also set to approximately 30 to 60 mm, so there is little protrusion when it is hung on the wall W, allowing for compact use.

[0030] In this embodiment, the hook F attached to the wall W is hung on the storage hole 10a, but it is also possible to attach a plate magnet to the back panel 11 and configure it so that it can be attached to a board to which a magnet can be attached.

[0031] 1 and 2, the portable wall-mounted fan A may be placed upright with the spacer 13 facing downwards, or may be placed with the back panel 11 facing downwards. When the spacer 13 is placed downwards, the air can be efficiently taken in through the holes 11a in the back panel 11. When the back panel 11 is placed downwards, the back panel 11 has a flat surface that faces the wall W. Therefore, the fan can be placed in a suitable position on a desk or the like, and the fan housing 20 can be raised and lowered and rotated to set the fan in a suitable position.

[0032] In this embodiment, the back plate 11 is formed in a flat plate shape as a flat surface that contacts the wall surface W, but the flat surface may be formed only on a part of the back plate 11.

[0033] Furthermore, in this embodiment, the spacer 13 is integrally formed as a cubic box housing the control member, but the spacer and the member housing the control member may be formed as separate members. [Explanation of symbols]
