Description

  The present invention relates to a fan that has a remote control and is used by being placed on a floor.

  Many modern fans are equipped with a remote control to improve usability. Since the remote control is used to operate from a remote location, it is generally at hand when used. Further, since the remote control is often taken out or stored at the time of starting or stopping the operation, it is desirable that the remote control storing portion is provided in an upper portion that can be taken in and out without squatting and on the back side that is difficult to see when stored.

  In addition, since electric fans are generally placed in a living room, there is an increasing tendency to emphasize design. In particular, the emphasized design is adopted for the outer parts such as the motor cover, and as a result, the outer parts tend to be designed larger than the built-in components. Therefore, a dead space is created inside the motor cover and is wasted.

  In order to prevent the remote controller from being lost, a separate remote controller holder is often attached to the support column of the fan, and the remote controller is stored therein (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2003-293983 (FIG. 1)

  In recent years, a fan equipped with a remote control has a separate remote control holder attached to the column of the fan as in Patent Document 1, and the remote control can be stored there. The mounting position can be changed in the vertical direction. However, the fan has a protective guard that surrounds the blades in front of the upper part of the support, and this protective guard interferes with remote control removal and storage, so it is not possible to place the remote control holder on the upper part of the support. Can not. For this reason, the remote control holder has to be placed at a relatively low position, and a dedicated remote control holder made of a separate member is provided so that the mounting position can be changed. There was the difficulty that workability was bad, such as not getting.

  As another remote control storage method, there is a type in which the remote control holder is hooked on the handle of the motor cover, but this method similarly requires a dedicated part made of a separate member. Note that, in the attachment type in which the remote control holder is hooked on the handle, the remote control storage portion is disposed above, so that the posture of the remote control can be taken out and stored easily. However, if the remote control holder is hung beside the motor cover, the design will be lost. In addition, the problem remains that the workability is poor because the remote control holder is in an unstable state due to hanging.

  The present invention has been made to solve at least one of the problems as described above, and an object of the present invention is to eliminate the need for a dedicated part for housing the remote control and to reduce the number of parts. .

  The electric fan according to the present invention is a electric fan having a remote controller, and the electric motor is covered with an electric motor cover, and the electric motor cover is recessed from an outer peripheral surface of a portion where a space exists inside the electric motor cover. A remote control storage unit for storing the remote control is provided.

  In the electric fan according to the present invention, since the electric motor cover and the remote control storage unit are integrated, a dedicated part for storing the remote control becomes unnecessary, the number of parts can be reduced, and the cost can be reduced.

FIG. 8 is a cross-sectional view of the rear cover of the electric motor cover of the electric fan according to the embodiment of the present invention as viewed from the right side and an enlarged view of the abutting portion of the front cover.
The motor cover 20 is formed by a bottomed cylindrical front cover 2 and a rear cover 6 as shown in FIGS. 3 and 4, and the front cover 2 and the rear cover 6 are attached to each other on the opening side ends. The state is separably coupled. The front cover 2 and the rear cover 6 each have a surface shape opposite to the abutting portion. On these surfaces, the front cover 2 is the motor 1 and the rear cover 6 is the gear box (swing mechanism) 8. Respectively. That is, the front cover 2 has an electric motor fixing hole 2b through which the front cover fixing male screw 9 is inserted on the bottom side and a protective guard fixing male screw portion 2a on the bottom side as shown in FIGS. 3 and 5, and the electric motor fixing hole 2b. It is fixed to the electric motor 1 by a front cover fixing male screw 9 inserted into the protective cover 11, and a protective guard 11 surrounding the blade 12 is fixed to the protective guard fixing male screw portion 2a. Further, as shown in FIGS. 3, 4 and 8, the rear cover 6 is fixed by a rear cover fixing male screw 10 which is inserted into the rear cover fixing hole 6f and fixed to the screw hole on the gear box 8 side. Yes. In addition, the rear cover 6 is recessed from the outer peripheral surface of the portion where the dead space 6a exists as shown in FIGS. 3, 4, 6, and 8, so that the rectangular remote controller 30 is provided. Is provided with a remote control storage portion 6c. Further, the front cover 2 is provided with a handle 5 as shown in FIGS. 3 to 5 and FIG. 7, and the abutting portion between the front cover 2 and the rear cover 6 is the handle 5 as viewed in plan. It is supposed to be covered by.

  The remote control housing 6c has one inner wall surface constituted by the bottom wall 6e of the rear cover 6, and a plurality of guide ribs 6b extending in the depth direction are provided on the inner surface of the remote control housing formed by the bottom wall 6e. The remote controller 30 can be sandwiched and held between the plurality of guide ribs 6b and the wall surface 6g facing the plurality of guide ribs 6b.

The bottom wall 6e of the rear cover 6 is formed in a dish shape that curves inwardly as shown in FIG.
As a result, the strength can be secured with a shape that does not impair the design, the mold is not complicated, and the cost can be reduced.

  In addition, the depth direction dimension of the remote control housing 6c is set so as to substantially match the short direction dimension of the rectangular remote controller 30.

FIG. 9 is a rear view showing a state where the remote controller is housed in the remote controller housing portion of the electric motor cover of the electric fan according to the embodiment of the present invention. FIG. 10 is a top view showing a state where the remote controller is housed in the remote controller housing portion of the electric motor cover of the electric fan according to the embodiment of the present invention.
As described above, the rear cover 6 is formed in a bottomed cylindrical shape, the remote controller 30 is formed in a symmetric rectangular shape, and the depth direction dimension of the remote control storage portion 6c is the short direction of the rectangular remote controller 30. It is set to almost match the dimensions. For this reason, when the remote controller 30 is housed in the remote controller housing 6c, the remote controller 30 becomes almost invisible as shown in FIGS. 9 and 10, and the appearance is improved. Further, when the remote controller is taken out, both corners of the remote controller 30 are out of the storage portion, so that both corners can be easily picked up with fingers.

Next, details of the attaching portion between the front cover 2 and the rear cover 6 will be described with reference to FIGS. 6 to 8 with reference to FIGS. FIG. 11 is a perspective cross-sectional view showing a further enlarged portion of the front cover and the rear cover of the electric motor cover of the electric fan according to the embodiment of the present invention. FIG. 12 is an exploded perspective cross-sectional view further enlarging and showing the attachment portion of the front cover and the rear cover of the electric motor cover of the electric fan according to the embodiment of the present invention.
As shown in FIGS. 11 and 12, an arcuate flange 7 into which the opening side end 4 of the front cover 2 can be fitted is formed on the attachment portion of the rear cover 6 so as to protrude outward. A taper 7a is formed in which the inner edge of the arc has an acute angle. Further, a flange 3 with which the end of the arc-shaped flange 7 can come into contact with the rear cover 6 of the front cover 2 is formed to protrude outward, and the end of the arc-shaped flange 7 of the flange 3 is formed. A taper groove 3a that matches the taper 7a of the arcuate flange 7 is provided on the end face on which can be contacted.

  Therefore, when the front cover 2 and the rear cover 6 are attached and joined together, the taper 7a at the end of the arcuate flange 7 of the rear cover 6 is fitted into the taper groove 3a of the flange 3 of the front cover 2. Then, the front cover 2 is sandwiched and restrained between the flange 3 and the opening-side end 4 so that the abutting portions of the front cover 2 and the rear cover 6 are integrated. For this reason, when the product is lifted by the handle 5 provided on the motor cover 20, the opening side end portion 4 of the front cover 2 fitted in the arc-shaped flange 7 is lifted upward, that is, lifted by the load. Even if it is deformed in the direction, the arcuate flange 7 is also pushed upward along with it, and these are deformed as a unit, and it is possible to prevent the attachment part from being displaced or coming off. .

  Further, since the arc-shaped flange 7 of the rear cover 6 and the flange 3 of the front cover 2 are formed so as to protrude outward, the thickness in the direction in which the abutting portion deforms (in the radial direction of the cylinder) increases. As a result, the strength can be increased and the deformation itself can be kept small. Furthermore, this effect is combined with the restraining effect of the taper 7a of the arc-shaped flange 7 by the taper groove 3a of the flange 3 described above to increase the strength of the handle 5 and to hold the product when the handle 5 is lifted. The deformation of the hand 5 can also be suppressed small. For this reason, it becomes possible to ensure the strength without screwing the vicinity of the handle 5 to the built-in object. Furthermore, since the arc-shaped flange 7 and the flange 3 that are formed to protrude outward are covered with the handle 5 in a plan view and become inconspicuous, strength can be ensured without impairing the design, and the degree of freedom in design Will also increase.

  Further, when the product falls backward, an impact is generated in which the rear cover 6 is strongly pressed against the front cover 2 side. However, as described above, the taper 7a at the end of the arc-shaped flange 7 of the rear cover 6 is The rear cover 6 is inserted into the tapered groove 3a of the flange 3 of the front cover 2 and is sandwiched and restrained between the flange 3 of the front cover 2 and the opening side end portion 4, so that the rear cover 6 is located inside the front cover 2. The rear cover 6 is prevented from entering the front cover 2 or coming out of the front cover 2. At this time, the rear cover 6 also protects the remote control 30 housed in the remote control housing portion 6c provided on the outer peripheral surface of the portion where the dead space 6a exists in the rear cover 6 so as to be recessed from the surface. Is done.

  A similar effect can be obtained by mechanically fixing to the electric motor 1 or the gear box (swing mechanism portion) 8 or the like housed in the vicinity of the joint portion of the front and rear covers 2 and 6. Therefore, it is necessary to form a fixing structure on the opening side of the bottomed cylindrical front cover 2 and rear cover 6 having a closed surface on one side, which complicates the mold structure, increases the mold cost, and assembles. The productivity becomes worse with the increase in complexity and cost of parts. By adopting the configuration as described above, it is not necessary to form a fixing structure on the opening side of the bottomed cylindrical front cover 2 and rear cover 6, and strength is achieved while realizing the same cost and assembling performance as in the past. Can be secured.

  Since the electric fan 100 according to the embodiment of the present invention is configured as described above, the electric motor cover 20 and the remote control storage unit 6c are integrated, so that a dedicated component for storing the remote control is not necessary, and the number of components is reduced. And cost reduction is possible. Further, since the remote control storage 6c is provided on the outer peripheral surface of the portion where the space exists in the motor cover 20 so as to be recessed from the surface, not only the remote control 30 to be stored, but also the remote control storage 6c. The number of exposed portions is reduced, and the design can be ensured accordingly. Furthermore, since the remote control housing 6c is disposed above the support column 21, the remote controller 30 can be easily taken in and out, and the workability is improved.
