Description

The present invention relates to, for example, a fan powered by a rechargeable battery pack for a power tool.

A fan using a rechargeable battery pack does not need to be connected to, for example, an AC 100V household power supply. Therefore, it can be carried and used in various places such as construction sites. At construction sites and the like, battery packs for power tools are used as power sources for power tools such as electric drills and screw tighteners. By making the battery pack for power tools available for the electric fan, the convenience of the electric fan will be enhanced.

Patent Document 1 discloses an electric fan using a battery pack for a power tool. The pedestal described in Patent Document 1 has legs that stand up against the installation surface. Battery packs with output voltages of, for example, 14.4V, 18V, etc. are mounted in the space between the pedestal and the installation surface along the bottom surface of the pedestal. Since the battery pack is located below the pedestal and the main body, the center of gravity of the fan is located below the installation surface. Therefore, the posture of the fan installed or installed on the installation surface is stable.

In recent years, battery packs for larger power tools having an output voltage of 36 V or the like have been provided. By making it possible to use a large battery pack, the convenience of the electric fan will be improved. However, in order to mount a large battery pack on the battery mounting portion of Patent Document 1, it is necessary to provide long legs. Therefore, the stability of the posture of the fan becomes low. Further, for example, a battery pack having an output voltage of 14.4V, 18V, etc. is attached to a fan having long legs. This creates a dead space between the battery pack and the installation surface. Therefore, it is difficult to make the fan compact.

As mentioned above, there was room for various improvements in the battery-powered fan so that a large battery pack could be attached. Therefore, a battery-powered fan to which a battery having a large capacity can be attached has been conventionally required.

According to one feature of the present disclosure, the battery-powered fan has an electric motor, blades rotated by the electric motor, and a main body housing for accommodating the blades. The battery-powered fan has a pedestal and a battery mount. The pedestal supports the main body housing upright against the installation surface. The battery mounting portion is provided on the rear surface of the pedestal on the upstream side of the blower of the blade, and the battery that supplies electric power to the electric motor can be attached and detached along the rear surface of the pedestal.

Therefore, the battery mounting portion is provided on the pedestal that is installed or mounted on the installation surface to stabilize the posture. Therefore, the posture of the battery-powered fan is stable when the battery is attached to the battery attachment portion and used. Since the battery mounting portion is provided on the rear surface of the pedestal and the battery can be attached and detached along the rear surface of the pedestal, a large size battery can be mounted.

According to other features of the present disclosure, the pedestal has a pedestal body, left and right legs, and a connecting portion. In a posture in which the pedestal is located below the main body housing, the pedestal main body rotatably supports the main body housing in the left-right direction or the up-down direction. The left and right legs extend from both the left and right sides of the pedestal body, and the distance between them increases in the left-right direction as they go downward. The connecting portion connects the left and right legs below the pedestal body. Therefore, the left and right legs have a so-called divergent shape in which the distance becomes wider toward the bottom. Therefore, the postures of the main body housing and the pedestal with respect to the installation surface can be more stabilized. Furthermore, the strength of the pedestal is increased by connecting the left and right legs with the connecting portion. This makes it possible to improve the stability of the posture of the pedestal.

According to other features of the present disclosure, the pedestal body has a saddle shape in which the central portion is located below the left and right sides in the front view. Here, the saddle shape refers to a shape such as a V-shape or a U-shape that is convex downward when viewed from the front. Therefore, the main body housing is supported by the pedestal main body at a position close to the installation surface in the central portion of the pedestal main body. Therefore, the position of the center of gravity of the battery-powered fan becomes low. This makes it possible to improve the stability when installing or mounting the battery-powered fan on the installation surface.

According to another feature of the present disclosure, the battery mounting portion is configured to be mounted by sliding the battery from top to bottom, and overhangs below the pedestal body. Therefore, the battery can be easily mounted with the battery-powered fan installed or mounted on the installation surface. By extending the battery mounting portion below the pedestal body, the position of the center of gravity of the battery-powered fan is lowered. As a result, the stability of the installation of the battery-powered fan can be improved even when a large and heavy battery is installed.

According to another feature of the present disclosure, a handle having an uneven shape is provided in the lower surface front region of the pedestal body. Therefore, when the user holds the handle and holds the battery-powered fan, the battery does not interfere with the grip of the handle. Moreover, the battery is located on the lower side when gripping the handle. Therefore, the center of gravity of the battery-powered fan to which the battery is attached is located near the lower part of the handle. This makes it possible to have a good balance with respect to the weight of the battery.

According to other features of the present disclosure, the left and right legs extend vertically to support the pedestal body at a distance from the installation surface, and the left and right standing legs and the lower end of each standing leg along the installation surface. It has left and right installation legs that extend both front and back. Therefore, it is possible to achieve a good balance in the left-right direction. Furthermore, it can be installed in a well-balanced and stable posture in the front-back direction.

According to other features of the present disclosure, the connecting portion connects the left and right installation legs. The pedestal body, the left and right legs, and the connecting portion have an isosceles trapezoidal shape with the connecting portion as the long side when viewed forward. Therefore, the main body housing can be supported by a pedestal that has high strength and can be installed in a stable posture with respect to the installation surface.

According to another feature of the present disclosure, the main body housing has a front housing and a rear housing that can be separated in the front-rear direction, and a plurality of recesses arranged side by side along the outer circumference. Therefore, a finger can be hooked on the recess when separating the front housing and the rear housing. Therefore, the front housing and the rear housing can be easily separated.

According to another feature of the present disclosure, the battery is a rectangular box-shaped rechargeable battery pack that can be used as a power source for power tools. Therefore, the battery for power tools can also be applied to a battery-powered fan. Also, because it is a rechargeable battery pack, it can be used repeatedly. Therefore, the convenience of the battery-powered fan is increased. Since the battery has a rectangular box shape, it can be arranged compactly. Therefore, the battery-powered fan can be installed on various installation surfaces.

According to other features of the present disclosure, the left and right legs extend vertically to support the pedestal body at a distance from the installation surface, and the left and right standing legs and the lower end of each standing leg along the installation surface. It has left and right installation legs that extend both front and back. The connecting portion connects the left and right installation legs. The pedestal body, the left and right legs, and the connecting portion have an isosceles trapezoidal shape with the connecting portion as the long side when viewed forward. The battery is a rectangular box-shaped rechargeable battery pack that can be used as a power source for power tools. Therefore, the battery-powered fan can be installed in a well-balanced and stable posture in the left-right direction and the front-back direction. In addition, the main body housing can be supported by a pedestal that has high strength and can be installed in a stable posture with respect to the installation surface. Rechargeable and reusable batteries for power tools can also be applied to battery-powered fans. Further, since the battery has a rectangular box shape, it can be arranged compactly. Therefore, the battery-powered fan can be installed on various installation surfaces.

As shown in FIGS. 1, 2, and 7, the central portions of the left and right installation legs 24 are connected by a plate-shaped connecting portion 25 extending in the left-right direction. The pedestal body 21, the left and right leg portions 22, and the connecting portion 25 form an isosceles trapezoidal shape when viewed from the front. The connecting portion 25 has a plate thickness direction in the vertical direction. The connecting portion 25 overlaps with the main body housing 13 in the vertical direction. The connecting portion 25 has stepped portions 25b whose height changes when viewed in the left-right direction on both the left and right sides. The central portion of the connecting portion 25 sandwiched between the left and right stepped portions 25b is lowered to substantially the same height as the lower surface of the installation leg portion 24. A plurality of circular holes 25a are provided between the left and right stepped portions 25b so as to penetrate the connecting portion 25 in the plate thickness direction. The connecting portion 25 can be attached to, for example, a tripod by utilizing the circular hole 25a. As a result, the fan 1 can be attached to the tripod.

As described above, the electric fan 1 has an electric motor 11, a blade 12 rotated by the electric motor 11, and a main body housing 13 for accommodating the blade 12, as shown in FIG. The fan 1 has a pedestal 20 and a battery mounting portion 26. The pedestal 20 supports the main body housing 13 by standing up against the installation surface F. The battery mounting portion 26 is provided on the rear surface 21d of the pedestal 20 on the upstream side of the blower of the blade 12, and the battery 27 that supplies electric power to the electric motor 11 is detachable along the rear surface 21d of the pedestal 20.

Therefore, the battery mounting portion 26 is provided on the pedestal 20 which is installed or mounted on the installation surface and whose posture is stable. Therefore, the posture of the fan 1 when the battery 27 is attached to the battery attachment portion 26 and used is stable. Since the battery mounting portion 26 is provided on the rear surface 21d of the pedestal 20 and the battery 27 is detachable along the rear surface 21d of the pedestal 20, a large size battery 27 can be mounted.

As shown in FIGS. 1 and 2, the pedestal 20 has a pedestal main body 21, left and right leg portions 22, and a connecting portion 25. In a posture in which the pedestal 20 is located below the main body housing 13, the pedestal main body 21 rotatably supports the main body housing 13 in the left-right direction or the up-down direction. The left and right legs 22 extend from both the left and right sides of the pedestal body 21 and are spaced downward from each other in the left-right direction. The connecting portion 25 connects the left and right leg portions 22 below the pedestal main body 21. Therefore, the left and right leg portions 22 have a so-called divergent shape in which the distance becomes wider toward the bottom. Therefore, the postures of the main body housing 13 and the pedestal 20 with respect to the installation surface F can be more stabilized. Further, the strength of the pedestal 20 is increased by connecting the left and right legs with the connecting portion 25. This makes it possible to improve the stability of the posture of the pedestal 20.

As shown in FIG. 2, the pedestal body 21 has a saddle shape in which the central portion is located below the left and right sides when viewed forward. Therefore, the main body housing is supported by the pedestal main body 21 at a position close to the installation surface F in the central portion of the pedestal main body 21. Therefore, the position of the center of gravity of the fan 1 becomes low. This makes it possible to improve the stability when installing or mounting the fan 1 on the installation surface F.

As shown in FIGS. 4 and 5, the battery mounting portion 26 is configured to be mounted by sliding the battery 27 from the top to the bottom, and extends below the pedestal main body 21. Therefore, the battery 27 can be easily mounted with the fan 1 installed or mounted on the installation surface F. By projecting the battery mounting portion 26 below the pedestal body 21, the position of the center of gravity of the fan 1 is lowered. As a result, even when a large and heavy battery 27 is attached, the stability of the installation of the fan 1 can be improved.

As shown in FIG. 7, a handle 21f having an uneven shape is provided in the lower surface front region of the pedestal main body 21. Therefore, when the user grips the handle 21f and holds the fan 1, the battery 27 does not interfere with the grip of the handle 21f. Moreover, the battery 27 is located on the lower side when gripping the handle 21f. Therefore, the center of gravity of the fan 1 to which the battery 27 is attached is located near the lower part of the handle 21f. As a result, the battery 27 can be held in a well-balanced manner with respect to the weight of the battery 27.

As shown in FIGS. 2 and 5, the left and right leg portions 22 extend in the vertical direction and support the pedestal body 21 at a distance from the installation surface F. It has left and right installation legs 24 that extend both front and rear along the installation surface F. Therefore, it is possible to achieve a good balance in the left-right direction. Furthermore, it can be installed in a well-balanced and stable posture in the front-back direction.

As shown in FIGS. 2 and 7, the connecting portion 25 connects the left and right installation leg portions 24. The pedestal body 21, the left and right leg portions 22, and the connecting portion 25 have an isosceles trapezoidal shape with the connecting portion 25 as the long side when viewed forward. Therefore, the main body housing can be supported by the pedestal 20 which has high strength and can be installed in a stable posture with respect to the installation surface F.

As shown in FIGS. 5 and 6, the main body housing 13 has a front housing 13a and a rear housing 13b that can be separated in the front-rear direction, and a plurality of recesses 13h arranged side by side along the outer periphery. Therefore, a finger can be hooked on the recess 13h when separating the front housing 13a and the rear housing 13b. Therefore, the front housing 13a and the rear housing 13b can be easily separated.

As shown in FIGS. 3 and 5, the battery 27 is a rectangular box-shaped rechargeable battery pack that can be used as a power source for a power tool. Therefore, the battery 27 for power tools can also be applied to the electric fan 1. Also, because it is a rechargeable battery pack, it can be used repeatedly. Therefore, the convenience of the electric fan 1 is increased. Since the battery 27 has a rectangular box shape, it can be arranged compactly. Therefore, the fan 1 can be installed on various installation surfaces F.

Various changes can be made to the fan 1 described above. The battery 27 is not limited to the illustrated output voltage, and may have an output of, for example, 10.8V or 14.4V. The battery mounting portion 26 may be configured to attach / detach the battery 27 in the left-right direction. The connecting portion 25 may be, for example, a columnar shape, a cylindrical shape, a rod shape, or the like. It can also be applied to a fan that does not have a swing mechanism 28. Further, it may be applied to a fan having no rotation mechanism of the main body housing 13 by the left-right rotation support portion 15c or the up-down tilt support portion 15b. Instead of the detachable structure of the front housing 13a and the rear housing 13b by the removal button 14, for example, the front housing 13a may be rotated in the circumferential direction to be screw-engaged with the rear housing 13b.
