Abstract

PURPOSE:To share parts by providing a base removable from a main body and a stanchion removably connecting the main body to the base below the main body having a blade, a motor and guards. CONSTITUTION:A base 23 removable from a main body 18 is provided below the main body 18 having a head 6, a blade 4, a motor 5 and guards 1, 3. The main body 18 and the base 23 are removably connected with a stanchion 19. The main body 18 is taken out from a tube body 20 and connected directly to the base 23, thus this fan can be changed from one for use on floor to another for use on desk. Accordingly, one set of a product can be used for many purposes, and parts can be shared.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure of an electric fan that can cope with a change in capacity of 2%.

[Conventional technology]

Figures 15 and 16 are 2, for example, Meikai Sho 52-1039.
FIG. 48 is a perspective view showing a conventional rocky shore shown in Publication No. 48.

In the figure, (1) is a column, and a groove (2) is formed at the upper end to which a main body (not shown) consisting of a blade, a movable groove, a guard, etc. is attached. (3) is a switch box in which the lower side of the support (1) is formed to extend in one direction, and (4) is a base, in which a fitting groove (5) is formed in the center portion along the longitudinal direction.

The conventional electric fan is constructed as described above, with the switch box (3) inserted into the fitting #+51 of the base (4), and the support (1)
The electric fan is assembled by attaching the main body to the groove (2) of the fan.

Usually, there are various types of electric fans, such as those for tatami rooms and those for tabletops.
The height of the pillar (1) differs depending on the purpose. Pillar (
1) There are some that have adjustable lengths, but there are limits to this.It is well known that special supports (1) are used for tatami room and tabletop use.

[Problem that the invention seeks to solve]

The problem with the conventional scrap machine mentioned above is that it is necessary to use a special support (1) depending on the purpose, so it is not possible to use a tatami room type for a tabletop use, or a tabletop type for a tatami room use. There is. Another problem is that each part is dedicated and cannot be shared to increase productivity.

This invention was made to solve the above problems, and it can be used for sitting mosquitoes, tabletops, floors, etc. with one product.
Another object of the present invention is to provide an electric fan that can improve productivity by sharing parts.

[Failure to solve the problem]

The electric fan according to the present invention includes a main body having one blade, an 'iac motor, and a guard, a base disposed below the main body and removably connected to the main body, and one support that removably connects the main body and the base. It has been established.

[Effect]

In this invention, one main body and the base are removably connected directly or via a support, so if the two main bodies and the base are directly connected, the overall height of the electric fan can be reduced.

If they are connected via struts, the overall height will be increased.

[Embodiment] Figures 1 to 14 are diagrams showing one embodiment of the present invention, in which Figure 1 is a front view of a 1-tist machine for tatami rooms, Figure 2 is a right side view, and Figures 3 to 14 are diagrams showing examples of the present invention.

(72) is a B ring fitted into the tip of screw Qυ, (
73) is screw 2! Fitted into υ, tube body ■ and fixing plate (71)
A pressure spring (75) is fixed to the inside of the lower end of the pipe body (2) and has a female thread on the inside that is similar to the female thread of the pipe support (64); This is a cord case cover provided on the lower surface of the bottom plate (2).

In the electric fan configured as described above, when power is supplied to the single blade electric motor (5), the two blades (4) are rotated to blow air through the front guard (1).

On the other hand, when power is supplied to the two-head oscillating motor (4η).

The crank iron rotates and causes the rod (51) to reciprocate.

This movement is transmitted to N (55). As a result, the arm (55) performs a rocking movement about its axis, and the arm (55)
The spindle (
45) and the neck piece (9) to swing the support (to). With this, the two heads (6) make nine swing movements. Also.

When the main body Ql is rotated in the horizontal direction, the ball (68) rolls on the uneven surface (64c) of the 'a support (64),
Do 9 double head movements. In addition, when one head (6) is tilted forward or backward, the neck piece (9) is given an appropriate return force by the tension spring (40) of the elevation adjustment plate (end), and the neck piece (9) is It is held in a predetermined position by the action of the ball Q4).

Although the above configuration is for use in a tatami room, it can also be used as a tabletop by removing the two main bodies (I8) from the pipe body 4 and directly connecting the two main bodies α to the base (2).

Attachment and detachment of the tube body (2) in this case will be explained.

First, as shown by the solid line in Fig. 1, the fixing plate (71) is placed in a position away from the inner wall of the tube body (4), and the groove (64d) and screw (66) are secured to the main body α barrel. Insert the lower end of the locked tube support (64) into the upper end of the tube (1). Then, when the screw Qυ is rotated, the fixed plate (71) is guided by the guide (70) and moves to the right in the figure.
The tip of the tube engages the hole (64e) of the tube support (64) as shown by the dashed line. The tube support (64) is now fixed to the tube body (a), and is prevented from being pulled out upwards. The operation when removing the main body Ql is the reverse of the above. After removing the pipe body ■, insert the pipe support (6) directly into the center hole of the base (C), and tighten the pipe fixing screw (4) with the pipe support (6) female thread (
64b), it can be used as a tabletop as shown in FIGS. 8 and 9.

Note that the cord (2) is pulled out from the tube support (64) through the support u9 and the base @, as shown in FIGS. 10 and 11.

The electric fan is packaged as shown in FIGS. 12 to 14. That is, the whole is divided into three parts: the main body αυ, the support α9, and the four bases, and is stored in an outer box (81) with a packaging material (82) interposed therebetween. At this time, unlike conventional electric fans, 9
Since there is no rearward protruding portion of the head 9+61, packaging can be done in close contact, and the outer box (81) can be made smaller.

As mentioned above, the support post +1 (l) can be attached and detached, and one product can be used in two types, one for a tatami room and one for a tabletop.

If a longer support is used, it can also be used on the floor and can be applied to a wide variety of models.

〔Effect of the invention〕

As explained above, in this invention, it is not for two blades and two blades.
A main body having a sJJm and a guard, a base disposed below the main body and removably connected to the main body, and a support that removably connects the two main bodies and the base are provided.
One product can be used for tabletop and floor use, and productivity can be improved by sharing parts.
This has the effect of making the packaging box smaller.
