Abstract

A stand type electric fan (except a sirocco fan type tower type electric fan) having a propeller can be operated in an easy posture while standing. In a propeller type fan (excluding a sirocco fan type tower type fan), the remote controller 8 can be operated to the top of the fan (above the top of the propeller guard and the motor cover 3 is equal to or higher than the top of the propeller cover). Operability and visibility can be improved by installing using the holder 9 separate from the electric fan. If unnecessary, it is possible to prioritize the design by removing the holder 9.

Description

The present invention relates to a propeller-type fan that has an operation unit and is used on a floor (excluding a sirocco fan-type tower fan and a fan without a wing).

Many of the general electric fans composed of propeller guards, electric motors, props, and bases are equipped with an operating section on the base, and it is necessary to bend when operating the switch or to bend the waist and press the switch near the floor. For example, there was an unreasonable attitude. It is desirable that such a fan can be operated in an easy posture while standing .

For this purpose, it is desirable that the operation unit be provided at a position and an angle that can be easily operated with a finger with good visibility when standing in front of the electric fan.

   In order to improve the operability and visibility of the electric fan, the operation unit is moved from the base to the support (see, for example, FIGS. 1, 5, and 6 of Patent Document 1), a wireless operation unit (hereinafter referred to as a remote controller) (Refer to FIG. 1 of Patent Document 2, reference numeral 30 of FIG. 2 and FIG. 1 of Patent Document 3).

JP-A-10-61588 JP 2013-185562 A Utility model No. 2539988

The present invention makes it possible to operate the fan in an easy posture and with good visibility while standing the switch operation of the electric fan.

  A general electric fan is mainly provided with an operation unit on the base, but in recent years, an electric fan on the upper surface of a support or a motor cover has been released. However, these fans are good in design but not enough in operability. Among the types of electric fans, there is a sirocco fan type tower type electric fan, and a wired switch is provided on the upper surface. This is because the wiring design is easy, and a general propeller type fan has not been implemented because it is difficult to set a switch on the top of the fan.

  In addition to the operation part of the base, in the case of a fan with a remote control, it can be attached to the support, stored in the center of the propeller cover (Patent Document 2), or stored on the rear surface of the motor cover (Patent Document 3). However, it is a storage method that prioritizes design and is not sufficient in operability.

  The remote control is convenient because it can be placed at hand, but when it is removed from the fan, it often forgets where it was placed, and it is often found that it is operated with the fan body switch.

  The propeller fan according to the present invention (excluding a sirocco fan tower fan) is installed in a state where the remote controller can be operated on the upper part of the fan.

  In the electric fan which concerns on this invention, visibility and operativity are excellent compared with the conventional machine by the remote control operation part being provided in the upper part of the electric fan.

1 to 5 show an embodiment of the present invention, which is a specific example in the case where an operation unit is provided in a fan. As shown in the figure, in order to improve operability, an operating portion is provided in the vicinity of the top of the electric fan, above the propeller guards 1 and 2 or the motor cover 3.

When attaching the operating part to the propeller guard, most guards are made of thin metal wires. 6 to 9 are detailed views of a method of fixing the operation unit using a wire. As shown in the figure, there can be various places to be provided, but here, as a representative example, four examples in the case of being attached to the front surface of the propeller guard in FIG. 1 will be described.

As shown in FIG. 6 , a remote controller that does not require wiring is suitable for the operation unit, and may be an infrared method, a wireless method, or anything else. In order to attach to the propeller guard, the holder 9 is required, and the holder 9 is provided with a fixing claw 11 for fixing to the propeller guard according to the pitch of the wire. A positioning slit 10 is also provided to prevent the holder from moving left and right. Further, as a method of fixing the remote control to the holder, a recess 15 on the side of the remote control is provided and the remote control is held using the projection 14 of the fixing claw 13 of the holder 9.
The convex 12 is for positioning the remote control, and the back of the remote control is concave. The holder fixing claw shown in the figure is an example, and the position, quantity, and shape are not limited to this.

FIG. 7 shows an embodiment in which a holder is provided as a general-purpose part to a commercially available fan. Since the propeller guards of commercially available electric fans have different wire spacings and diameters depending on the manufacturer, the holder needs to cope with them. The slider 21 solves this problem. The holder 9 is attached to the guide hole 22 from the left and right. Concave portions are provided on the slider surface at regular intervals, and the widths of the left and right sliders 21 can be adjusted by fitting with the convex portions provided inside the guide holes 22. The slider 21 is provided with a hook 24 for fixing the wire, and after being attached to the propeller guard, the slider is narrowed so as to be aligned with the interval of the wire and the holder is fixed. Since the shape of the remote controller for a commercial fan varies depending on the manufacturer, the adhesive mat 23 is used for fixing to the holder. Although this mat is fixed at the time of operation in order to adsorb the remote control appropriately with a weak adhesive material, it can be easily removed and used.

FIG. 8 is for fixing the holder 9 from the back side of the propeller guard using screws 32. In order not to be affected by the fixed strength and the wire spacing, the holder 9 has screw holes 31 opened at regular intervals to accommodate various spacings, and can be attached to most guards. As for the method of attaching the guard, it is also possible to attach it to the guard by sandwiching it with a holder without using the screw 32. The remote control can be placed in the box using the recess 33 of the holder. It can also be fixed by the adsorption mat 24.

For FIG. 9 , the propeller guard 1 is almost always made of metal. If a metal plate 41 is molded on the upper surface of the guard during the manufacturing process and a remote controller 42 with a built-in magnet is installed, the remote controller can be fixed without using a holder as an accessory. The convex 43 is for positioning, and a concave is formed on the back surface of the remote control.

FIGS. 6 to 9 show examples of attaching the remote controller to the propeller guard, but the combination of the electric fan and the holder, and the remote controller and the holder are arbitrary.

FIG. 10 shows a propeller guard used in a DC electric motor fan that has been recently released. Many of the upper surfaces are cylindrical, and most are made of resin. For this reason, the shape of attaching the holder can be freely integrally molded, so various installations can be considered, but an example is shown. The claw 52 of the propeller guard 6 is fitted into the groove 51 provided in the remote control.

11 and 12 show an embodiment in which the motor cover is installed on the upper surface. Motor cover can be almost easily attached by forming as the shape for mounting the remote control holder for a resin shown in Figure 11. The remote controller 8 and the holder 70 may be integrated or separated, and the notch 71 of the holder 70 and the hook 72 of the motor cover 3 are fitted and fixed.

FIGS. 13 and 14 (detailed drawings) show examples of attachment when the handle 7 is formed on the motor cover 3. In this case, the holder 70 may be attached to the upper surface of the motor cover 3 as shown in FIG. 13 , but the holder 80 may be attached using the handle 7. As an example of the attachment method, there is a method in which a hook 82 is provided on the side surface of the handle 7 and a notch 81 formed in the holder 80 is inserted and fitted from above.
